Abstract
BACKGROUND Radial head fractures are common elbow fractures in adults, and their treatment algorithm remains controversial. Particularly with displaced Mason III or IV radial head fractures, studies have shown mixed results when comparing outcomes between radial head arthroplasty (RHA) and open reduction internal fixation (ORIF). Although multifactorial, patient characteristics often play a large role in treatment modality. The purpose of this study was to analyze the current trend in the management of radial head fractures, complications, and need for repeat operation among these groups. MATERIALS AND METHODS We conducted a retrospective database review using the IBM Truven MarketScan Databases and analyzing all available patients treated for radial head fractures between 2015 to 2020. Patients were grouped by treatment modality, including nonoperative, ORIF, radial head excision (RHE), and RHA. Patient characteristics, complication rates, reoperation rates, and predictive factors for undergoing surgery were assessed. RESULTS Our search yielded 18,945 cases of radial head fractures that underwent treatment. The majority of patients were managed nonoperatively (16,035), and fewer were treated via ORIF, RHA, and RHE (1,636, 1,174, and 100, respectively). Of these, between 1% and 2.5% of patients in each group underwent revision surgery. CONCLUSION We found that patients who undergo RHA or RHE are typically older and have more comorbidities compared to patients who are treated nonoperatively or undergo ORIF. We found no significant difference in reoperation rates based on initial mode of treatment. Male sex, osteoporosis, coronary artery disease, and a displaced fracture are predictive of undergoing surgery for a radial head fracture. [Orthopedics. 202x;4x(x):xx-xx.].

Abstract
Background Owing to the great variety of fracture patterns and limitations of the standard radiographic investigation, all the already available classification systems for radial head and neck fractures (RHNFs) are limited by a poor-to-moderate degree of intraobserver and interobserver reliability. Although computed tomography (CT) is being increasingly used to better understand the fracture characteristics, a CT-based classification system of RHNFs is still lacking. Therefore, in this agreement study, we aimed to propose a classification system based on two-dimensional and three-dimensional (2D/3D) CT to test the hypothesis that this classification has good intraobserver and interobserver reliability. We have also provided a treatment algorithm. Methods Our proposed classification-Proximal and Articular Radial fractures Management (PARMa)-is based on 2D/3D CT imaging. It is divided into four types based on different fractures patterns. The 2D/3D scans of 90 RHNFs were evaluated in a blinded fashion by eight orthopedic and one radiology consultant, according to the proposed classification. The first phase of observation aimed to estimate the interobserver agreement. The second phase involved a new observation, 4 weeks after the first analysis, and estimated the intraobserver reliability. The standard radiographs of these 90 fractures were also evaluated by the same observers, with the same timing and methods, based on the same classification. Cohen's Kappa was applied for intraobserver agreement. Fleiss's Kappa was used both within and among the evaluators. Kendall's coefficient of concordance was employed to determine the strength of association among the appraisers' rankings. Furthermore, Krippendorff's alpha was chosen as an adjunctive analysis to assess between evaluators' agreement. Results For the intraobserver agreement, Fleiss' Kappa statistics confirmed the consistency (overall kappa values: 0.70-0.82). Cohen's Kappa statistics aligned with Fleiss' Kappa, with similar kappa values and significant P values (P < .001). For interobserver agreement, Fleiss' Kappa statistics for between appraisers showed moderate-to-substantial agreement, with kappa values ranging from 0.54 to 0.82 for different responses. The results relating to the appraisers' observation of standard radiographs showed that the overall Fleiss' Kappa values for intraobserver agreement ranged from 0.34 to 0.82, whereas Fleiss' Kappa statistics for interobserver agreement ranged from 0.40 to 0.69. Conclusions The proposed classification system is expected to be reliable, reproducible, and useful for preoperative planning and surgical management. Both 2D and 3D CT allow the identification of the magnitude and position of displacement and articular surface involvement.

Abstract
Objective We aimed to assess the recent trends in the demographics of radial head and neck fractures and their management based on displacement. Methods TriNetX was queried for cases from 1 January 2017, through 31 December 2022. ICD diagnosis codes were used to define patient cohorts with radial head or neck fractures. CPT codes were searched to determine the operative patient cohorts. All cases not included under any CPT codes were defined as the nonoperative cohort. Results A total of 103,432 patients were included. The female-to-male ratio was 4:3. The average age of individuals with radial head fractures was 43 ± 25 years, with a greater age in the replacement cohort compared to the fixation group. The incidence rates of displaced and nondisplaced fractures were similar across the years. Nonoperative management was overwhelmingly preferred over operative management. Regarding operative management, internal fixation rates were higher than replacement rates. Conclusion The trend of fracture incidence and the type of operative management has remained constant over the past 6 years. However, an increase in the number of radial head replacements is expected with an aging population. Moreover, radial head and neck fractures are among the benign injuries most frequently managed nonoperatively.

Abstract
BACKGROUND Radial head fractures (RHF) represent about one-third of all elbow fractures, comprising approximately 2%-5% of all fractures sustained. The aims of this systematic review and meta-analysis are as follows: (i) to compare complications rate in patients undergoing radial head arthroplasty (RHA) or open reduction and internal fixation as surgical treatments for Mason type 3 RHF; (ii) to compare clinical outcome and functional score in patients undergoing RHA or ORIF in Mason type 3 RHF. METHODS Following the preferred reporting items for systematic reviews and meta-analyses guidelines, a comprehensive literature systematic review of literature was conducted up to March 2024. All prospective studies were included. The analysis employed the log odds ratio (OR) and 95% confidence interval (CI) as the outcome measure. RESULTS Six studies were incorporated into the systematic review. A total of three studies, published between 2009 and 2021, were included in the meta-analysis. A cohort of 169 patients affected by Mason 3 RHFs was collected. The ORIF group included 65 patients, and 26 events of complications after ORIF were observed. RHA group, instead, consisted of 70 patients, and 8 events of complications were identified. CONCLUSION Our findings reveal that the Mason type 3 RHFs treated with open reduction and internal fixation, exhibits a higher risk of complications compared to those patients treated with RHA. Moreover, the standardized mean difference analysis suggests that the ORIF group demonstrates a lower mean Broberg and Morrey Elbow score in comparison to the RHA group, with a higher functional recovery in RHA group.

Abstract
Plate fixation is a common treatment option for radial head fractures (RHFs). Due to the benefits of less invasiveness and fewer complications of internal fixation, the application of small-diameter headless compression screws (HCSs) to treat RHFs has become a new trend. This study aimed to compare the mechanical stability of four distinct internal fixation protocols for transversely unstable RHFs via finite element analysis. Using computed tomography data from 10 patients, we developed 40 patient-specific FE models of transversely unstable RHFs fixed by parallel, crossed, and tripod HCSs and mini-T plate (MTP). Under simulated physiological loading of the elbow joint, the construct stiffness, displacement, and von Mises stresses were evaluated and verified by a biomechanical experiment. Under shear loading, the MTP group exhibited lower construct stiffness, larger displacement, and higher Von Mises stress than the HCSs group. The stiffness of tripod HCSs was greater than parallel and crossed screw fixation techniques. There was a strong relationship between apparent bone density and construct stiffness (R = 0.98 to 0.99). In the treatment of transversely unstable RHFs, HCSs have superior biomechanical stability than MTP. The tripod technique was also more stable than parallel and crossed fixation.

J Shoulder Elbow Surg 2024; 33:2022-2032.

Abstract
BACKGROUND The tripod screw configuration has been shown to offer similar stiffness characteristics to a laterally placed plate. However, concern has been raised that the construct may be prone to failure in scenarios where the screw intersects at the fracture line. We performed a finite element analysis to assess potentially ideal and unideal screw placements in the tripod construct among Mason III radial head fractures. METHODS A 3-dimensional proximal radius model was developed using a computed tomography scan of an adult male radius. The fracture site was simulated with a uniform gap in transverse and sagittal planes creating a Mason type III fracture pattern comprising 3 fragments. Three configurations were modeled with varying screw intersection points in relation to the radial neck fracture line. A fourth configuration comprising an added transverse interfragmentary screw was also modeled. Loading scenarios included axial and shear forces to simulate physiological conditions. Von Mises stress and displacement were used as outcomes for analysis. RESULTS Some variation can be seen among the tripod configurations, with a marginal tendency for reduced implant stress and greater stiffness when screw intersection is further from the neck fracture region. The construct with an added transverse interfragmentary screw demonstrated greater stiffness (2269 N/mm) than an equivalent tripod construct comprising 3 screws (612 N/mm). CONCLUSION The results from this study demonstrate biomechanical similarity between tripod screw constructs including where screws intersect at the radial neck fracture line. An added fourth screw, positioned transversely across fragments, increased construct stiffness in our model.

Abstract
PURPOSE We hypothesized that multiple absorbable screws/K-wires would be effective for native head preservation in comminuted radial head fracture fixation (com-RHFs). METHODS Seventeen patients who met the inclusion criteria between 2018 and 2020 were included. Radiologic findings indicating proper union and clinical outcomes such as the range of elbow motion, visual analog scale score, and Mayo Elbow Performance Score were assessed prospectively after surgery and at least three years of follow-up. RESULTS The mean follow-up period was 4.6 years. Eleven, one, three, and two patients presented with isolated com-RHFs, type 2 (accompanied injury of medial collateral ligament), type 4 ("terrible triad") fractures, and type 5 posterior olecranon fracture-dislocations, respectively. Union was achieved after a mean of nine weeks postoperatively. The head and shaft angles did not differ significantly from the contralateral normal values (p = 0.778 and 0.872, coronal and sagittal, respectively). At the final follow-up, the mean flexion-extension/pronation-supination arcs were 126.47 ± 4.92°/135.59 ± 10.13°, and thus were significantly different from those on the contralateral side (p < 0.001, both), however the arcs were functional ranges for ordinary daily life. Also, functional status was satisfactory in all individuals. The arthritis grade and extent of heterotrophic ossification were satisfactory in all cases, and there were no serious complications requiring revision surgery. CONCLUSIONS Absorbable screw/K-wire fixation for com-RHFs is an option before radial head arthroplasty associated with a low complication rate and no need for revision.

Abstract
Background Management of radial head fractures around the elbow with open techniques can predispose to edema, postoperative pain, and adhesions. The resultant limitation in elbow range of motion negatively affects functional outcomes. Rehabilitation is then rendered a challenge in a joint with proneness to stiffness. Hypothesis Arthroscopic percutaneous fixation of Mason type 2 radial head fractures would provide satisfactory radiological and clinical outcomes. Study Design Case series; Level of evidence, 4. Methods A total of 24 patients diagnosed with isolated Mason type 2 radial head fractures at a single institution between February 1, 2021, and December 31, 2021, received arthroscopic percutaneous fixation by headless screws. Functional evaluation included Mayo Elbow Performance Score and postoperative elbow range of motion measurements. Radiological evaluation was performed using elbow radiographs and computed tomography scans. Patients were evaluated for a minimum of 24 months. Results This study included 12 male and 12 female participants with a mean age of 37.29 ± 11.93 years. At the end of the follow-up period (mean, 27.75 months; range, 24-32 months), the mean elbow flexion was 140.17° ± 8.21° and the extension deficit was 4.17° ± 3.81°. The Mayo Elbow Performance Score revealed 21 patients with excellent results and 3 patients with good results. All patients returned to preinjury activities at a mean time of 3.1 months (range, 2-6 months) postoperatively. Union was reached in all patients at a mean time of 7.63 weeks (range, 6-10 weeks). No neurological complications or reoperations were reported at the end of the follow-up period. Conclusion Arthroscopic fixation was demonstrated to be a valid and valuable technique for managing isolated Mason type 2 radial head fractures. It allowed for accurate reduction without the need for soft tissue dissection, resulting in excellent clinical outcomes.

Orthop Traumatol Surg Res 2024; 110:103593. [PMID: 36924883 DOI: 10.1016/j.otsr.2023.103593] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 02/10/2023] [Accepted: 02/23/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND The optimal treatment for different types of displaced partial articular radial head fractures is still debatable. Fractures involving the articulating portion of the radial head can be defined also as bi-articular and are often underestimated. Moreover, the complete loss of periosteal contact between fracture fragments is a marker of instability. Available classifications do not emphasize these aspects. The purpose of the present study is to describe two assessment methods to identify fractures involving the articulating portion of the radial head and complete loss of periosteal contact with the help of 2D-3D CT scan. The second purpose is to propose a classification of the displaced partial articular radial head fractures basing on these two assessment methods. HYPOTHESIS We hypothesize that the proposed classification is reliable. PATIENTS AND METHODS By observing the position of the bicipital tuberosity with respect to the ulna in reference to the coronal plane in the 3D-CT scan and by observing the location of the fracture fragment in the 2D axial scan, it is possible to understand if a displaced partial articular fracture involves the articulating portion of the radial head. Also, it is possible to understand the presence or absence of a complete loss of periosteal contact between the two fracture fragments by observing the coronal and sagittal 2D-CT scans. We identified 20 displaced partial articular radial head fractures on a series of 149 patients with radial head fractures. Following the above-described assessment methods, these 20 fractures were classified in three subgroups. Also, seven evaluators were asked to use these assessment methods to classify these 20 fractures in the three subgroups, in order to evaluate inter- and intra-observer agreement. RESULTS Eight fractures involved the non-articulating portion of the radial head with complete loss of periosteal contact, eight involved the non-articulating portion of the radial head without complete loss of periosteal contact, and four involved the articulating portion of the radial head with or without complete loss of periosteal contact. The kappa for intra-observer reliability ranged from 0.46 to 0.84. The average kappa for inter-observer reliability was 0.570 (range: 0.526 to 0.676). The Kendall's coefficient for inter-observer concordance was 0.673. DISCUSSION Prognostically, displaced partial fractures of the articulating portion of the radial head could differ from the other types, regardless of whether or not there is a complete loss of periosteal contact. Underestimating this fracture pattern can lead to poor results due to risk of forearm rotation blockage. Moreover, underestimating complete loss of periosteal contact in displaced partial fractures of the non-articulating portion of the radial head could lead to poor results. The described evaluation methods have moderate reliability, but can represent, along with other described methods, a good starting point to better understand and treat these insidious fractures. LEVEL OF EVIDENCE III; retrospective study.

Abstract
Background: The integrity of the radial head is critical to maintaining elbow joint stability. For radial head fractures requiring surgical treatment, headless compression cannulated screw fixation is a less invasive scheme that has fewer complications. The aim of this study was to compare the mechanical stability of different fixation devices, including headless compression cannulated screws and mini-T-plates, for the fixation of transversely unstable radial head fractures. Methods: Forty identical synthetic radius bones were used to construct transverse unstable radial head fracture models. Parallel, cross, and tripod headless compression cannulated screw fixation and mini-T plate fixation were applied. The structural stiffness of each group was compared by static shear loading. Afterward, cyclic loading was performed in each of the three directions of the radial head, and the shear stability of each group was compared by calculating the maximum radial head displacement at the end of the cycle. Findings: The mini-T plate group had the lowest structural stiffness (51.8 ± 7.7 N/mm) and the highest relative displacement of the radial head after cyclic loading (p < 0.05). The tripod headless compression cannulated screw group had the highest structural stiffness among all screw groups (p < 0.05). However, there was no significant difference in the relative displacement of the radial head between the screw groups after cyclic loading in different directions (p > 0.05). Interpretation: In conclusion, the biomechanical stability of the mini-T plate for fixation of transverse unstable radial head fractures is lower than that of headless compression cannulated screws. Tripod fixation provides more stable fixation than parallel and cross fixation with headless compression cannulated screws for the treatment of transversely unstable radial head fractures.

Ha C, Lee JK, Kim S, Jo S, Chung J, Han SH. Incidence and pattern of concurrent capitellum fracture associated with radial head and neck fractures. Orthop Traumatol Surg Res 2023; 109:103531. [PMID: 36572382 DOI: 10.1016/j.otsr.2022.103531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 11/02/2022] [Accepted: 12/12/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND Radial head and neck fracture is a common fracture around the elbow. It is mostly caused by axial or valgus loading after a fall in elbow extension and forearm pronation. When a radial head and neck fracture occurs, the capitellum collides with the radial head and experiences a shear force, leading to capitellum fracture. The primary aim of this study was to evaluate the incidence of concurrent capitellum fracture and analyze its patterns among patients treated for radial head and neck fractures based on computed tomography. Secondary aim is to determine factors associated with concurrent capitellum fractures. HYPOTHESIS Capitellum fractures are more common than expected in radial head and neck fractures and show a consistent pattern. With the higher the Mason type fracture, the higher the incidence of concurrent capitellum fracture will be shown. METHODS A total of 101 patients treated surgically (27 patients) or non-surgically (74 patients) for radial head and neck fractures from January 2017 to December 2020 were retrospectively analyzed. Initial computed tomography was reviewed to identify concurrent capitellum fractures. A fracture was diagnosed when the bone continuity was lost in two consecutive images in any one of the three directions of computed tomography scan images. Seventeen patients with capitellum fractures were classified as group 1 and 84 patients without capitellum fractures as group 2. Each group of patients was assessed using Mason classification, whether fracture extended to the radial neck or not, fracture location, and treatment method. To determine the fracture location, radial head was trisected using three anatomical landmarks: safe zone, posteromedial zone, and anteromedial zone. And it was determined as the location where the fracture was most comminuted. RESULTS The average age of the 101 patients was 44.6 years old. There were 54 (53.5%) males and 47 (46.5%) females. Capitellum fracture was accompanied in 17 cases. Its incidence was 16.8%. The rate of accompanying capitellum fracture was 9.5% (6/63) for Mason type 1, 25.0% (6/24) for Mason type 2, and 41.7% (5/12) for Mason type 3. The ratio of radial neck extension of fracture was significantly higher in group 2. There was no isolated radial neck fracture in group 1. However, there were 33 in group 2. After eliminating isolated radial neck fracture patients, significantly more fractures were located in the safety zone in group 1. Group 1 had a significantly higher rate of surgical treatment than group 2 (52.9% (9/17) vs. 21.4% (18/84) p=0.007). CONCLUSION For radial head and neck fractures, the higher the Mason type fracture, the higher the incidence of concurrent capitellum fracture. When the fracture extended to the radial neck, the comorbidity of the capitellum fracture was decreased. Among radial head fractures, when the fracture was located in the safe zone, the comorbidity of capitellum fracture was increased. The rate of surgical treatment was higher in radial head and neck fracture patients with concurrent capitellum fractures. LEVEL OF EVIDENCE IV; diagnostic study.

Abstract
OBJECTIVE To explore the clinical outcomes of MasonII/III radial head fractures without the neck involvement treated with pre-curved metacarpal plates. METHODS Ninety cases of Mason typeII/III radial head fractures without the neck involvement were retrospectively collected from the department of orthopaedics of our hospital from September 2015 to May 2021. Group A (n = 44) underwent open reduction and internal fixation with pre-curved metacarpal plate, and Group B (n = 46) were fixed by traditional T-shaped plates. The operation time and the incision length were recorded during the operation. The Mayo Elbow Performance Score (MEPS), Disability of Arm, Shoulder and Hand (DASH) score, visual analogue scale (VAS) for pain, range of motion (ROM) and post-operative complications were evaluated at the last follow-up. RESULTS All the patients were followed up for at least 12 months. There were no significant difference between two groups regarding operation time (54.2 ± 12.1 v.s 51.3 ± 7.2, mins), MEPS (88.9 ± 4.2 v.s 87.8 ± 4.4), DASH score (7.3 ± 4.6 v.s 9.0 ± 4.0), VAS (1.6 ± 0.8 v.s 1.7 ± 0.7), and ROM. However, the incision length was shorter in Group A (5.6 ± 0.5 v.s 6.6 ± 0.5, cm, P < 0.01). The postoperative complication rate was also lower in Group A (1/44 v.s 8/46, P = 0.02). CONCLUSION Masson II/III radial head fractures without the neck involvement treated with pre-curved metacarpal plates could achieve satisfactory outcomes comparable to traditional T-shaped plates. Moreover, the invasiveness and postoperative complications are less in patients with pre-curved metacarpal plates. LEVEL OF EVIDENCE III, retrospective comparison study.

Treatment of comminuted radial head fractures with personalized radial head prosthesis produced with 3-dimensional printing technology. J Shoulder Elbow Surg 2023; 32:463-474. [PMID: 36403925 DOI: 10.1016/j.jse.2022.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 09/30/2022] [Accepted: 10/12/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND The radial head is the forearm's pivot point for supination-pronation. Although radial head resection can be performed in comminuted radial head fractures, radial head prosthesis has gained popularity in order to prevent possible complications such as progressive valgus instability in the elbow and secondary ulnocarpal impaction that may develop due to proximal displacement of the radius. As for radial head prostheses, standard prosthetic designs do not provide the same results in everyone, and the alignment of the radial head and radial neck angle cannot be fully achieved. We believe that the radial head must be reconstructed with a complete anatomical implant. We designed and applied personalized prostheses to our patients, and in this study, we wished to share the 2-year results of these patients. METHODS In this study, 23 patients who had comminuted radial head fractures had personalized radial head prostheses inserted. Preoperative variables such as type of injury, age, side, additional ligament injury, operation time, number of radial head parts, neck angle of individual prosthesis, stem length, and stem diameter were noted. The mean operating time was 26 ± 9 minutes. One month postoperatively, after physical therapy, elbow range of motion, loss of strength compared to the opposite joint, Mayo elbow scores, QuickDASH scores, and patient satisfaction were evaluated. Patients were evaluated 2 years postoperatively. RESULTS QuickDASH and Mayo elbow scores were satisfactorily good (mean QuickDASH score: 9.091, mean Mayo score: 91.08). According to the results of the patient satisfaction questionnaire, 16 of the 23 patients reported excellent satisfaction, 5 patients good satisfaction, and 2 patients moderate satisfaction. None of the patients reported poor results. DISCUSSION Since personalized radial head prosthesis consists of a single monoblock, its surgical application consists of a single step and has a short operating time. As the applications in the literature increase and more studies are conducted, this subject will be better understood. Our study demonstrated that these patients, whose anatomies were individually replicated, achieved good range of motion and patient satisfaction. In fact, none of the patients reported negative results. In comminuted radial head fractures, surgical implantation of personalized radial head prosthesis is a treatment modality with easy application, short operating time, and good functional results.

Abstract
Introduction The objectives of this study were to assess long-term outcomes, complications, and reoperations after open reduction internal fixation (ORIF) of radial head fractures. Materials and Methods 35 adult patients, who underwent ORIF of an isolated, displaced radial head fracture without elbow instability (Mason classification type II or III) at two tertiary care referral centers from 2000 to 2017, were identified. Patient satisfaction, pain, and QuickDASH scores were assessed by telephone follow-up at median 12.9 years. Results The mean age of the 35 patients in our study was 39 years, and 54% were women. The median length of clinical follow-up was 175 days. Postoperative complications occurred in 54% of patients, and reoperations in 23% of patients. Multivariable logistic regression identified fixation with plate and screws versus screws alone as a risk factor for complications and reoperations. The long-term telephone follow-up response rate was 54%. At 13-year median follow-up, the average patient satisfaction was 9.6/10, the average patient-reported pain was 0.7/10, and the average QuickDASH score was 10.5. Conclusion The long-term outcomes of ORIF of Mason classification type II and III radial head fractures are favorable; however, rates of complication and reoperation are notable and may be higher with plate-and-screw fixation.

J Shoulder Elbow Surg 2022; 31:2506-2513. [PMID: 36115618 DOI: 10.1016/j.jse.2022.07.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 07/14/2022] [Accepted: 07/29/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND Radial head arthroplasty (RHA) is an important tool in the acute treatment of comminuted radial head and neck fractures. RHA is also performed in a delayed manner after failed open reduction and internal fixation, for fracture malunion or nonunion, and other chronic post-traumatic elbow disorders where restoration of the lateral column of the elbow is considered necessary. The relative efficacy and longevity of acute vs. delayed RHA is unknown. We sought to compare clinical, radiographic, and patient-reported outcomes between these groups. METHODS We identified patients ≥18 years old who underwent an RHA between 2000 and 2018 and then extracted 135 total elbows with a mean follow-up of 2.3 years that sustained isolated radial head fractures (30%), terrible triad injuries (66%), or Essex-Lopresti injuries (4%). The acute cohort (RHA: <12 weeks) contained 101 elbows that underwent surgery at a mean of 0.6 weeks (range, 0 days to 7 weeks, 96% <2 weeks) from injury, whereas the delayed cohort (RHA: 12 weeks to 2 years) contained 34 elbows that underwent surgery at a mean of 36 weeks (range, 14-82 weeks) from injury. Patients in the acute group had a higher percentage of terrible triad injuries (75% vs. 40%, P < .001) and Mason 3 fractures (98% vs. 45%, P < .001). RESULTS At the final follow-up, 13 of 101 patients in the acute cohort (13%) and 7 of 34 patients in the delayed cohort (21%) required implant revision or resection. A total of 25 patients (25%) in the acute cohort and 12 patients (35%) in the delayed cohort required a reoperation. Kaplan-Meier 2-year survival estimates free of implant resection or revision (90% acute, 86% delayed) and reoperation (76% acute, 70% delayed) were similar between groups. In patients with 5-year follow-up, there was an increased rate of revision or resection in the delayed group (30% vs. 13%). Two-year survival estimates free of radiographic loosening were 80% in the acute cohort vs. 57% in the delayed cohort (P = .04). Mayo Elbow Performance Score at 2 years demonstrated mean scores of 83 and 79 in the acute and delayed groups, respectively, with 71% of the acute cohort and 64% of the delayed cohort achieving good or excellent scores. CONCLUSIONS Our results demonstrated that although 2-year Kaplan-Meier survival free of revision or resection estimates and reoperation rates was equivalent between the groups, the delayed group experienced worse Mayo Elbow Performance Score outcomes, a higher revision or resection rate at 5 years, and an increased rate of radiographic loosening.

Abstract
PURPOSE The aim of this prospective study was to assess the clinical and functional results of radial head reconstruction with an autologous bone graft from distal humerus in 12 patients, with a follow-up for a period of 24 months. METHODS From March 2017 to June 2018, we surgically treated 12 patients using an autologous bone graft from the lateral distal metaphysis of the homolateral humerus. Patients were divided into two groups: -Group A consisted of patients with previous failed ORIF for radial head fracture. Patients underwent revision surgery at an average time of 7 months (between 6 to 8 months) from the first surgery. All the patients reported pain during the elbow range of motion with no gross clinical signs or instability of the joint. They all presented standard X-ray and CT-scan of the elbow suggestive of non-union fracture. None of them presented osteoarthritic modification at the time of surgery. -Group B consisted of patients reporting acute irreparable radial head fractures. Patients were evaluated clinically at 6-, 12-, and 24-months duration according to Disabilities of the Arm. Shoulder and Hand (DASH), Mayo Elbow Performance Score (MEPS), and Visual analogue score for pain (VAS);, range of motion (ROM) was evaluated at 6 and 24 months after surgery. Plain radiographs on anteroposterior and lateral views of the elbow were evaluated at final follow-up. RESULTS In both, groups (A and B) patients showed a significant improvement with regards to VAS, MEPS, and DASH at each follow-up (p < 0.05). X-rays showed complete bone healing in all patients with no sign of mobilisation or loosening of the screws. One case in group A presented asymptomatic partial ossification of LUCL. No cases of fracture or residual pain at the donor site. Furthermore, no other complications such as infection, wound issues, elbow instability, elbow stiffness, ulnar neuritis, graft non-union were reported. CONCLUSIONS Distal humerus bone graft should be considered a reliable option for the treatment of acute fractures that are unrepairable fractures or revision surgery for failed ORIF of the radial head, especially among young patients where prosthesis may be reserved as a salvage procedure, and radial head resection is a damaging and is not considered desirable.

Abstract
OBJECTIVE To evaluate the long-term outcome in patients after radial head resection surgery for isolated Mason type III radial head fractures. DESIGN An observational retrospective case series. SETTING A Hand and Upper-Extremity Surgery Unit in a tertiary care center. PATIENTS Data were collected from files of patients who were operated between the years 1980 and 2020. Of 352 patients who underwent surgery for radial head fractures, 25 patients were eligible and were enrolled in the study. INTERVENTION All participants underwent radial head resection surgery and a follow-up clinical and radiographic evaluation by 2 senior orthopaedic surgeons. OUTCOME MEASUREMENTS Objective evaluation included active range of motion of the elbow and wrist joints, ulnohumeral angle, key pinch and grip measurements, and radiographic imaging of elbow and wrist joints. Subjective evaluation included visual analog scale measurements, disability of arm shoulder and hand questionnaire, Mayo wrist score, Michigan hand outcome, and Oxford elbow score. RESULTS The mean follow-up was 18 years. Mean elbow range of motion and mean grip strength were lower in the operated hand, as compared to the contralateral hand. Mean proximal radial migration was 1.6 mm. Mean results of visual analog scale, disability of arm shoulder and hand, Mayo wrist score, Michigan hand outcome, and Oxford elbow score indicated good functional outcome and high patient satisfaction. CONCLUSIONS In our study population, long-term functional outcomes after radial head resection were encouraging. Thus, this procedure may be considered as a surgical alternative when radial head reconstruction or replacement fails. LEVEL OF EVIDENCE Therapeutic Level IV.

A hybrid technique combining intramedullary pinning with extramedullary plate fixation in unstable and comminuted radial head fractures following on-table reconstruction. BMC Musculoskelet Disord 2021; 22:613. [PMID: 34243755 PMCID: PMC8272375 DOI: 10.1186/s12891-021-04498-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Accepted: 06/30/2021] [Indexed: 11/10/2022] Open
Abstract
Background Management of comminuted radial fractures remains controversial. Currently, the emergence of on-table reconstruction technique has made fixation in comminuted radial head fractures more viable. However, the present study reported an intro-operative unstable displacement from the reconstructed radial head to the neck during plate fixation, characterized by a poor radiocapitellar contact and incongruity between the radial head and neck. A hybrid technique combining with intramedullary pining was performed in our study to restore the normal alignment and maintain the stability of fixation. Therefore, the purpose of this article aimed to prove the feasibility of unstable comminuted radial head fractures treated with the extramedullary plate and intramedullary pinning fixation using titanium elastic nails. Methods The clinical, functional and radiographic outcomes of the groups were compared during follow-up. The radiographic examination was conducted to evaluate the status of bone union, heterotopic ossification and post-traumatic arthritis. The functional assessment was performed to evaluate clinical effects, which included measurements of range of motion (ROM) in the elbow, Visual Analog Scale (VAS) score, Elbow Self-Assessment score (ESAS), Mayo Elbow Performance score (MEPS), and Disabilities of the Arm, Shoulder, and Hand (DASH)Outcome Measure score. Results Thirteen patients with unstable fractures were participated with an average follow-up of (38.6 ± 4.5) months for the experimental group and (32.0 ± 6.3) months for the control group, respectively. The functional outcomes in the experimental group, including MEPS and DASH, were significantly superior to the control group. However, no significant difference was observed in the elbow ROM and VAS score between two groups. In the last follow-up, one patient with post-traumatic arthritis rated as grades 1 and two with heterotopic ossifications were observed in the experimental group. In the control group, degenerative changes were observed in three cases (grade 1 in two cases and grade 2 in one case) and heterotopic ossifications rated as grade I were found in two patients. Conclusion Collectively, intramedullary pinning with extramedullary plate fixation is feasible in unstable comminuted radial head fractures, which can be considered as a remedial surgery for on-table reconstruction technique.

Management strategies of pediatric ipsilateral olecranon with associated radial neck fractures based on multicenter experience. J Orthop Surg Res 2021; 16:232. [PMID: 33785028 PMCID: PMC8008540 DOI: 10.1186/s13018-021-02373-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Accepted: 03/21/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The ipsilateral olecranon with associated radial neck fractures does not include in the Bado classification of Monteggia fractures and equivalent lesions. The primary aims of this retrospective multicenter study were to characterize this type of injury and, noting its unique properties, evaluate the results of the treatment, determine the prognostic factors that influence the radiological and clinical outcome, and also give treatment strategies. METHODS Between July 2011 and July 2016, forearm fracture patient charts were retrospectively reviewed from seven pediatric trauma centers. Patients diagnosed with ipsilateral olecranon with associated radial neck fractures and followed up for at least 24 months were included. Fracture characteristics, treatment, outcome, and complications were assessed. The clinical outcome of treatments was evaluated by the Mayo Elbow Performance Score (MEPS) and the Flynn criteria. Fisher's exact test and ANOVA test were used; significance was defined as P < 0.05. RESULTS One hundred thirty-seven consecutive patients (54 girls and 83 boys) from 8292 forearm fractures patients, the mean age of 7.5 years (1.5 to 14.8), with fractures of the ipsilateral olecranon with associated radial neck fractures were identified. One hundred twenty-five patients had radiologic and clinical follow-up. According to a simplified classification system with "operate" and "don't operate" groups, including five subtypes proposed in this study, ipsilateral olecranon with associated radial neck fractures subtypes could be classified with significantly different characteristics and outcome in treatment and complications. CONCLUSIONS Fractures of the ipsilateral olecranon associated with the radial neck are not so rare as previously reported. Complications and poor outcomes were easy to encounter without knowing this type of fracture. Appropriate treatment strategies could be made according to a simple classification system based on the treatment result of follow-up. LEVEL OF EVIDENCE Retrospective comparative study; Level III.

[PMID: 32798123 DOI: 10.1016/j.jhsa.2020.05.029] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 04/24/2020] [Accepted: 05/25/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE We aimed to study the epidemiology of radial head fractures within a single national registry database while analyzing trends in available treatments. METHODS A retrospective analysis of data from 2007 to 2016 provided by a national inpatient database registry was performed using the International Classification of Diseases code for radial head fractures and associated German Procedure Classification (OPS) codes. All surgical interventions were evaluated according to fracture type, patient sex and age, and distribution differences over the last decade to detect changes in the treatment trends. The number of major revision procedures was identified and the revision burden for each procedure calculated. RESULTS Overall, 70,118 radial head fractures were included, with the annual number rising over 20% during this period. Women were significantly older than men (peak incidence, 55-64 years vs 30-39 years) and more frequently injured (women-to-men, 1.3:1). Surgical interventions increased during the study period, with locking plate fixation of comminuted fractures and radial head arthroplasty (RHA) becoming increasingly performed while radial head resections decreased. The revision burden differed significantly between the fixation techniques, with an increased occurrence of RHA revision procedures more recently. CONCLUSIONS The data show a higher number and incidence of surgical procedures, especially for comminuted radial head fractures over the study period. Open reduction and internal fixation remains the most frequently used option, with the use of new fixation devices (eg, locking plates) increasing. The use of RHA more than doubled over the past 10 years while the number of radial head resections decreased. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Abstract
BACKGROUND Radial head arthroplasty (RHA) has been commonly adopted for irreparable radial head fractures while little information is addressed on valgus type injury. The purpose of this study is to report long-term outcomes and radiographic analysis in RHA for valgus type injury with comparison to fracture dislocation injury. METHODS A retrospective cohort study was conducted in patients receiving unilateral RHA with loose-fit, modular metal prosthesis for irreparable radial head fractures between 2004 and 2012. Totally, 33 patients with a mean follow up of 9 years (range, 7 to 15 years) were enrolled and divided into two groups including 14 valgus injuries and 19 fracture-dislocations. Demographics of the patients, injury details, clinical and radiographic outcomes, and correlation analysis were investigated and compared between two groups. RESULTS In patient demographics, significant difference was noted in sex distribution (p = 0.001), lateral collateral ligament involvement (p = 0.000) and time from injury to RHA (p = 0.031) between two groups. No patient underwent subsequent removal or revision of prosthesis. Good to excellent results according to Mayo Elbow Performance Score (MEPS) was achieved in 13 and 14 patients in group A and B respectively. Final motion range and Disabilities of the Arm, Shoulder, and Hand score was significantly better in valgus injury group. Radiographic analysis demonstrated fewer patients in valgus injury group presented periprosthetic osteolysis with weak to moderate negative correlation between radiolucency score and MEPS. CONCLUSIONS With an average of 9 years follow-up, RHA using loose-fit, modular metal prosthesis achieves encouraging outcomes for both valgus injury and fracture dislocation. In valgus type injury, better motion range, lower disability score and lower incidence of periprosthetic osteolysis is noted while correlation analysis of radiolucency score suggests extended, long-term investigation.

Abstract
OBJECTIVES The available literature discussing optimal surgical management of Mason II and III radial head (RH) fractures without concomitant bone or ligamentous injuries is limited. We aim to help determine the appropriate management of these functionally significant injuries. DESIGN We present our retrospective cohort study of outcomes of surgically managed isolated, displaced RH fractures SETTING: Study from three trauma centres. PATIENTS/PARTICIPANTS Adults who underwent surgical treatment for isolated displaced RH fractures. INTERVENTION RH open reduction internal fixation (ORIF), replacement or excision MAIN OUTCOME MEASUREMENTS: Elbow range of motion (ROM), pain and function using Oxford Elbow Score (OES), Mayo Elbow Performance Score (MEPS), Patient-Rated Elbow Evaluation (PREE) and QuickDASH (QD). RESULTS Of 46 patients included (mean age 47 years and mean follow-up 48 months), 12 type II fractures were treated with ORIF and 34 type III injuries had ORIF (16), replacement (12) or resection (6). ROM was comparable in all groups, with mean arcs of flexion-extension of 131° and pronation-supination of 147°. Mean visual analogue score for pain was 1.3 in those treated with ORIF compared to 1.9 with arthroplasty and 2.5 with excision. Mean functional scores were 41, 92, 14 and 14 for OES, MEPS, PREE and QD, respectively. Complication rates were 39% for ORIF, 33% for arthroplasty and 33% for resection. Overall re-operation rate was 13%. CONCLUSIONS Functional outcome is similar in all groups of surgically treated patients with isolated, displaced RH fractures. Complication rates are higher than that reported previously in the literature but with low re-operation rates. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Minimally displaced or impacted radial neck fractures are commonly sustained after elbow trauma, although few require surgical treatment or result in lasting complications. Whereas they are rare, radial neck nonunion after this injury can have adverse implications for patient function and quality of life. The current study presents a case series of 8 radial neck nonunions after minimally displaced or impacted radial neck fractures. METHODS Using our institution's electronic medical record database, referred to as the Synthetic Derivative database, we performed a retrospective review of all radial neck fractures that presented to our institution over 15 years. RESULTS Of 472 minimally displaced or impacted radial neck fractures, 8 progressed to symptomatic nonunion. Average age of these patients was 54 ± 9.3 years. One patient presented with bilateral radial neck nonunions. CONCLUSIONS Nonunion after an impacted radial neck fracture is a rare yet frustrating outcome for patients and providers alike. Our results estimate the rate of symptomatic radial neck nonunion after minimally displaced or impacted radial neck fractures to be 1.7%. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
BACKGROUND Isolated intra-articular radial head (IARH) fractures in skeletally immature patients represent a rare injury. Despite their initial benign radiologic appearance, these fractures are at risk for progressive radial head subluxation and may end with degenerative irreversible changes of the radiocapitellar joint. The aim of this study is to highlight the seriousness of these injuries and the importance of early diagnosis and a proper follow-up to achieve optimal outcomes. METHODS We retrospectively reviewed 6 patients with IARH fractures treated at our institution between 2011 and 2016. All patients presented with Salter-Harris types III or IV fracture. Five of 6 fractures were initially undisplaced. Treatment, clinical, and radiographic results were analyzed. Patients were divided into 2 groups according to treatment: patients included in group A were treated conservatively, whereas patients of group B were treated with early surgery. The final functional outcome was assessed using the Oxford Elbow Score (OES). The Broberg-Morrey classification was used for the radiographic results. RESULTS Group A included 3 patients (average age, 11±2 y). They developed an initially missed posterior subluxation of the radiocapitellar joint that caused to all of them a painful elbow and limited range of motion (ROM). Despite rescue surgery, they all presented with limited ROM at the final follow-up, although no functional limitations (OES, 46.3±2.9). The radiographs showed early degenerative changes. Group B included 3 patients (average age, 11±1 y) all treated surgically within 1 week from the injury. They showed no limitation of ROM and good functional (OES, 47.7) and radiologic outcomes. CONCLUSIONS IARH fractures in skeletally immature children are deceptive injuries which are often underestimated. Surgeons should be aware of these fractures, especially when a discrepancy between the clinical signs and symptoms, and the radiologic appearance exists, as this may be the only red flag that allows their identification in the acute setting. An early and accurate diagnosis followed by prompt and more aggressive treatment when necessary is mandatory for successful results. LEVEL OF EVIDENCE Level IV-case series.

Abstract
We present three cases of proximal radioulnar translocation in adults. Although rare, it is most commonly seen in paediatric cases. There have been three previously documented cases in adults, all requiring surgery and associated with ulnohumeral dislocations. Two of our cases required operative intervention, whilst one was reduced closed and did not require stabilisation. Furthermore, we have for the first time shown that proximal radioulnar translocations can occur in isolation in adults without an ulnohumeral dislocation. LEVEL OF EVIDENCE: Level IV.

Abstract
INTRODUCTION Complex radial head fractures are difficult to treat. In cases where stable fixation cannot be achieved, radial head resection or primary arthroplasty are frequently performed. Ex situ reconstruction of comminuted fractures may also be an option. This technique has widely been neglected in the literature, and only two small case series report satisfactory results. The aim of the present case series was to determine the functional and radiological outcomes of ex situ reconstructed Mason III and Mason IV fractures. We expect that the on-table reconstruction of comminuted radial head fractures will lead to bony union with no avascular necrosis in the postoperative course, which will demonstrate that this operative procedure is a reasonable option. PATIENTS AND METHODS Two Mason type III and seven Mason type IV fractures (including four Monteggia-like lesions) were reconstructed ex situ. The mean age of the patients was 47 years (range 22-64). The clinical examination included RoM tests, elbow stability tests, and a neurological examination. The functional outcome was assessed with the MEPS and DASH score. The radiographic examination included a.p. and lateral views of the elbow to detect non-unions, inadequacy or loss of reduction, radial head necrosis, heterotopic ossifications and signs of posttraumatic arthritis. RESULTS The mean follow-up time was 39 months (range 11-64). The mean MEPS was 82 points (range 15-100), and the mean DASH score was 20 points (range 0-85). All ex situ-reconstructed radial heads survived, and no signs of avascular necrosis were observed. Bony union was achieved in all but one patient who presented with an asymptomatic non-union. Signs of posttraumatic arthritis were found in all patients. With regard to the radial head, neither secondary resection nor arthroplasty had to be performed. All patients returned to their pre-injury occupations. CONCLUSION Ex situ radial head reconstruction can be a reliable option in the surgical treatment of complex radial head fractures associated with severe elbow trauma. Even in the midterm follow-up, no signs of avascular necrosis were observed. Modern implants may even extend the indications for reconstruction in such cases.

Abstract
BACKGROUND The treatment of multifragment Mason type III fractures is challenging. Open reduction-internal fixation (ORIF), radial head arthroplasty, and in some cases, even radial head resection are the current options; however, each of these treatment methods is associated with characteristic benefits and complications. We present our experience with a radial head salvage procedure in comminuted radial head fractures irrespective of concomitant injuries, which are not accompanied by typical ORIF-related complications. METHODS The first group comprised 29 patients with multifragment Mason type III fractures treated surgically with biological radial head spacers (group S). The fragments were reduced and fixated in an extracorporeal manner, and the reconstructed radial head was placed in its anatomic position without fixation to the shaft. The second group comprised 12 patients treated with conventional ORIF using mini-fragment plates (group P). RESULTS Thirty patients were enrolled to undergo clinical and radiographic follow-up at an average of 76 months (range, 12-152 months). In group S, nonunion at the head-neck junction developed in 70% of the cases; however, the overall Mayo Elbow Performance Index averaged 94.8, which was superior to the average Mayo Elbow Performance Index of 83.1 in group P. Radiographic evaluation showed development of osteoarthritic changes in 75% of patients in group S and 62.5% in group P. None of the patients had wrist-joint pain. CONCLUSIONS Preserving the native radial head in comminuted Mason type III fractures without fixation to the radial shaft is a reliable option. Excellent functional results can be expected; however, the development of osteoarthritis cannot be impeded.

Abstract
BACKGROUND Contact stresses of radial head prostheses remain a concern, potentially leading to early capitellar cartilage wear and erosion. In particular, point contact or edge loading could have a detrimental effect. The purpose of this study was to compare 3 different types of radial head prostheses in terms of joint contact areas with each other and with the native situation. The hypothesis was that the joint contact areas would be lower after monopolar arthroplasty. METHODS Seven fresh-frozen cadaveric upper limbs were used. Radiocapitellar contact areas of a monopolar design, a straight-neck bipolar design, and an angled-neck bipolar design were compared with each other and with the native joint. After standardized preparation, polysiloxane was injected into the loaded radiocapitellar joint to create a cast from which the joint contact area was measured. Measurements were performed at 3 angles of elbow flexion and in 3 different forearm positions. RESULTS In the native elbow, contact areas were highest in supination. Elbow flexion had no significant effect on native and prosthetic joint contact areas. Contact areas were decreased for all types of arthroplasties compared with the native joint (from 11% to 53%). No significant contact area difference was found between the 3 designs. However, bipolar prostheses showed lateral subluxation in neutral forearm rotation, resulting in a significant decrease in the contact areas from pronation to the neutral position. CONCLUSIONS All types of radial head prostheses tested showed a significant decrease in radiocapitellar contact area compared with the native joint. Bipolar designs led to subluxation of the radial head, further decreasing radiocapitellar contact.

Haasters F, Helfen T, Böcker W, Mayr HO, Prall WC, Lenich A. The value of elbow arthroscopy in diagnosing and treatment of radial head fractures. BMC Musculoskelet Disord 2019; 20:343. [PMID: 31351457 PMCID: PMC6661091 DOI: 10.1186/s12891-019-2726-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Accepted: 07/17/2019] [Indexed: 12/04/2022] Open
Abstract
Background Surgical treatment of radial head fractures is increasingly performed arthroscopically. These fractures often feature concomitant injuries to the elbow joint, which may be under-diagnosed in the radiological examinations. Little is known about the diagnostic value of arthroscopy, the treatment options that arise from arthroscopically assisted fracture fixation and clinical results. We hypothesized that arthroscopy can detect additional concomitant injuries and simultaneously expands the therapeutic options. Therefore aim of this study was to compare arthroscopic and radiologic findings, to assess the distinct arthroscopic procedures and to follow up on the clinical outcomes. Methods Twenty patients with radial head fractures were retrospectively included in two study centers. All patients underwent elbow arthroscopy due to at least one of the following suspected concomitant injuries: osteochondral lesions of the humeral capitellum, injuries of the collateral ligaments or loose joint bodies. Preoperative radiological findings were compared to arthroscopic findings. Afterwards, arthroscopic treatment options and clinical outcomes were assessed. Results Arthroscopic findings led to revision of the classified fracture type in 70% (p = 0.001) when compared to preoperative conventional radiographs (CR) and in 9% (p = 0.598) when compared to computed tomography (CT) or magnetic resonance imaging (MRI). Diagnosis of loose bodies was missed in 60% (p < 0.001) of the CR and in 18% (p = 0.269) of the CT/MRI scans. Osteochondral lesions were not identified in 94% (p < 0.001) of the CR and in 27% (p = 0.17) of the CT/MRI scans. Percutaneous screw fixation was performed in 65% and partial radial head resection in 10%. Arthroscopy revealed elbow instability in 35%, leading to lateral collateral ligament reconstruction. After a mean follow up of 41.4 ± 3.4 months functional outcome was excellent in all cases (DASH-Score 0.6 ± 0.8; MEPI-Score 98.5 ± 2.4; OES-Score 47.3 ± 1.1). Conclusions Elbow arthroscopy has a significant diagnostic value in radial head fractures when compared to standard radiological imaging. Although statistically not significant, arthroscopy also revealed concomitant injuries in patients that presented with an uneventful MRI/CT. Furthermore, all intraarticular findings could be treated arthroscopically allowing for excellent functional outcomes.

Abstract
Background With the development of indirect three-dimensional (3D) printing technology, it is possible to customise individual scaffolds to be used in bone transplantation and regeneration. In addition, materials previously limited to the 3D printing (3DP) process due to their own characteristics can also be used well in indirect 3DP. In this study, customised β-TCP/chitosan scaffolds with the shape of rabbit radial head were produced by indirect 3D printing technology. Methods Swelling ability, porosity, mechanical characterisation, and degradation rate analysis were performed, and in vitro studies were also implemented to evaluate the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells (MSCs) on the scaffolds. CCK8 cell proliferation assay kit and alkaline phosphatase (ALP) staining solution were used to study cell proliferation and early ALP content at the scaffold surface. Moreover, the osteogenic differentiation of MSCs on scaffolds was also evaluated through the scanning electron microscopy analysis. Results β-TCP/chitosan scaffold has good performance and degradation rate, and in vitro cell experiments also confirm that the scaffold has adequate cytocompatibility and bioactivity. Conclusion This study provides a promising new strategy for the design of customised scaffolds for the repair of complex damaged tissues.

Abstract
PURPOSE OF REVIEW The purposes of this review are to discuss the management of shoulder and elbow fractures in athletes to optimize the return to sport and to highlight treatment impact on the return to play. RECENT FINDINGS Fractures of the shoulder and elbow can have profound implications in an athlete career. Recent technique of fractures management trended toward to preserve soft tissue which is critical for an early recovery in athletic population. Arthroscopy presents a strong interest for the treatment of intra-articular fracture, and minimally invasive approach as developed in humeral shaft fracture can be considered to avoid soft tissue damage. Non-articular, stable, and minimally displaced fractures are mainly treated conservatively. However, we encourage a more aggressive approach in shoulder and elbow injuries in the athletes including minimally invasive and stable fixation to preserve vascularity and muscle environment.

Abstract
Monteggia-like lesions encompass a wide spectrum of fractures of the forearm and elbow associated with dislocations, subluxations and ligamentous lesions. Many attempts have been made to classify these injuries, not only to understand their pathology but also to develop optimal treatments. Unfortunately, although some of these classifications are complete, they are either complex, not immediately usable, or not exhaustive. An orthopedic surgeon who aims to rapidly treat this kind of injury needs a visual classification, and knowledge of the best surgical approach. Monteggia like lesions do not allow for mistakes during surgery, as even a minor error could be prove detrimental to performing and completing all surgical steps. In this paper, based on our extensive experience in treating these rare lesions, we suggest a practical guide to the best surgical approach for various types of Monteggia like lesions. Some technical tips and pitfalls are also described.

Objective New angle-stable plates provide more stability and better anatomical fit than previous plates. Methods 22 patients treated with an angle-stable plate were included. Postoperative the outcomes were evaluated according to the scoring systems of Morrey, Radin and Riseborough. Results 3 patients received a score of excellent, 14 good, and 5 satisfactory. We detected 3 cases of implant failure and 2 cases of postoperative neurological damage. 3 patientes received a radial head necrosis. Conclusions Our results show that the angle-stable radial head locking plate can only be used in limited cases in the treatment of multi-fragment radial head fractures.

Abstract
BACKGROUND Radial head and neck fractures are the most common elbow fracture in the general adult population; however, the optimal treatment for radial head fractures remains a topic of ongoing clinical controversy. The purpose of this study was to determine the rate of return to function, complications, and reoperation following operative management of unstable radial head fractures in a young, active patient population with intense upper extremity demands. METHODS A military health care database was queried for all US military servicemembers undergoing open reduction with internal fixation (ORIF; Current Procedural Terminology [CPT] code: 24665) and radial head arthroplasty (RHA; CPT code: 24666) between 2010 and 2015. All patients with minimum 2-year follow-up were included. Univariate and chi-square analyses were performed to evaluate the association between potential risk factors and the primary outcome measures. RESULTS A total of 67 ORIF (n = 69 elbows) and 10 RHA patients were included. The average age was 31 ± 8.0 years. At mean follow-up of 3.5 ± 1.1 years, 90% of patients overall were able to return to active military service, 96% of which with unrestricted upper extremity function. Nearly one-third (31.2%) of patients developed at least 1 postoperative complication. RHA has higher overall complication rates (70% vs 48%) when compared with ORIF, but this finding did not reach statistical significance ( P = .073). However, RHA had significantly higher rates of implant failure (20% vs 2.9%, P = .0498). Seventeen (21%) individuals required reoperation, 5 of which (6.3%) were revision procedures. Dislocation, coronoid fracture, and concomitant ligamentous repair portended a significantly increased risk of sustaining 1 or more complications ( P < .05), while dislocation and requirement for ligamentous repair independently predicted revision surgery ( P < .05). CONCLUSIONS Arthroplasty and ORIF are both viable options for treating unstable radial head fractures in a young, athletic population, offering comparable return to function despite increased complications with RHA.

Use of Osteofasciocutaneous Fibular Free Flap and Radial Head Arthroplasty in Trauma for Limb Salvage and Continued Elbow Function. Case Rep Orthop 2018; 2018:8295736.

Abstract
Reconstructive flaps have revolutionized the ability of surgeons to restore function and cosmesis for patients. While reconstructive flaps have been used to bridge large defects due to oncologic or congenital maladies necessitating large debridements, few cases have observed salvage flaps in traumas which provide additional challenges secondary to an injury trajectory. This case report details use of an osteofasciocutaneous fibular free flap and radial head prosthesis to restore forearm function in a 64-year-old female with a comminuted fracture of the proximal radius. The patient has sustained a 5.5 cm epiphyseal radial defect with an associated 20 × 15 cm overlying tissue defect after serial debridement. In review of the literature, only one nontraumatic case using a combined free flap and radial head prosthesis for proximal forearm defect to restore joint function has been reported. We suggest that, for proximal forearm fractures, this technique can be used to restore elbow joint function in limb salvage.

Abstract
BACKGROUND Nondisplaced and minimally displaced fractures of the radial head and neck are common injuries, yet the role of physical therapy (PT) in their treatment is unclear. The aim of this trial was to assess the need for formal PT following a simple fracture of the radial head or neck. METHODS Patients who had a nondisplaced or minimally displaced fracture of the radial head or neck and presented to 1 of 2 providers were enrolled prospectively between January 2014 and August 2016. Patients were randomized to receive outpatient PT or perform self-directed home exercise. The follow-up intervals were 6 weeks, 3 months, 6 months, and at least 1 year. The outcome measures were Disabilities of the Arm, Shoulder and Hand (DASH) scores; pain; time to clinical healing; and range of motion. Demographic data were analyzed using the Mann-Whitney U test and Fisher exact test. Independent-samples t tests were utilized to compare outcome measures. RESULTS Fifty-one patients were enrolled in the study. The average follow-up was 16.6 months. Twenty-five patients were randomized to a home-exercise cohort, and 26 patients were randomized to a formal-outpatient-PT cohort. There were no significant differences in demographics between cohorts. At 6 weeks, the home-exercise cohort had better function as indicated by a significantly lower mean DASH score compared with the PT cohort (p = 0.021). At 3 months, 6 months, and final follow-up, there were no significant differences between cohorts for any outcome measure. CONCLUSIONS Patients who performed home exercises after sustaining a nondisplaced or minimally displaced fracture of the radial head or neck demonstrated better early function at 6 weeks compared with patients who received formal PT. After 6 weeks, there were no significant differences in outcomes. These data suggest that prescribing PT for patients who have an isolated nondisplaced or minimally displaced fracture of the radial head or neck is not cost-effective and that instructing the patient to perform self-directed exercises will be followed by a similar outcome.

Abstract
PURPOSE Optimal treatment strategies for radial head fractures remain a subject of debate. We examined national practice patterns in the management of radial head fractures to determine rates of surgical treatment, type of surgery employed, and the incidence of reoperation. METHODS Between 2007 and 2011, we identified patients with radial head fractures along with their associated injuries by International Classification of Diseases, Ninth Revision codes in a national database of orthopedic insurance records. For those who underwent surgery, the type of intervention was identified and each patient was observed to determine whether a subsequent procedure was needed by 1 and 2 years. Chi-square analysis was performed to make comparisons between groups. RESULTS A total of 58,404 radial head fractures were identified between 2007 and 2011; of these, 2,981 underwent surgical treatment (5.1%). Rates of surgical intervention were significantly higher in the context of associated injuries. Among the 2,981 radial head fractures treated surgically, 57.1% underwent open reduction internal fixation (ORIF), 37.9% were treated with radial head arthroplasty, and 4.9% underwent radial head excision. When the surgically treated radial head fracture was associated with a coronoid fracture, elbow dislocation, or proximal ulna fracture, 64.2%, 54.3%, and 47.2% were treated with arthroplasty, respectively, compared with 32.6%, 41.9%, and 52.6% treated with ORIF, respectively. After initial surgical treatment, 12.7% and 14.4% of radial head fractures that underwent ORIF required a secondary surgery at 1 and 2 years, respectively, compared with 8.6% and 10.7% of radial head arthroplasties and 8.3% and 8.4% of resections. CONCLUSIONS Rates of arthroplasty were significantly higher in the context of associated injury, particularly in the setting of a coronoid fracture or elbow dislocation. Fractures initially treated with ORIF had a higher rate of revision surgery at both 1 and 2 years after the index procedure compared with arthroplasty. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic II.

Abstract
BACKGROUND Whereas most radial head fractures are stable injuries, they sometimes occur as part of complex injury patterns with associated elbow instability. Radial head arthroplasty has been favored in patients with unreconstructable radial head fractures and unstable elbow injuries. The purpose of this study was to review radiographic outcomes, functional outcomes, and complications after radial head arthroplasty for radial head fracture in unstable elbow injuries. METHODS This study was a retrospective review of radial head fractures treated with radial head arthroplasty by a single surgeon during a 15-year period. Demographics of the patients, injury details, operative reports, radiographic and clinical outcomes, and any complications were recorded. Patients were divided into stable and unstable elbow injury groups. RESULTS A total of 68 patients were included. There were 50 unstable fractures that were compared with 18 stable fractures. Patients with unstable radial head fractures with associated elbow dislocation achieved mean flexion and mean forearm rotational arc of motion similar to that of patients with stable radial head fractures. However, supination loss was greater in the unstable group than in the stable fracture group, with a mean difference of 10°. Radiographic outcomes and complication rates did not differ between injury groups. There was no observed decrease in implant longevity in patients with unstable elbow injuries. CONCLUSIONS Radial head arthroplasty is an effective option for treatment of unstable elbow injuries, with recovery of functional elbow range of motion and no difference in complication rate or implant survivorship compared with those patients with stable injuries.

Abstract
Background: Radial head fractures are common elbow injuries in adults and are frequently associated with additional soft tissue and bone injuries. Methods: A literature search was performed and the authors’ personal experiences are reported. Results: Mason type I fractures are treated non-operatively with splinting and early mobilisation. The management of Mason type II injuries is less clear with evidence supporting both non-operative treatment and internal fixation. The degree of intra-articular displacement and angulation acceptable for non-operative management has yet to be conclusively defined. Similarly the treatment of type III and IV fractures remain controversial. Traditional radial head excision is associated with valgus instability and should be considered only for patients with low functional demands. Comparative studies have shown improved results from internal fixation over excision. Internal fixation should only be attempted when anatomic reduction and initiation of early motion can be achieved. Authors have reported that results from fixation are poorer and complication rates are higher if more than three fragments are present. Radial head arthroplasty aims to reconstruct the native head and is indicated when internal fixation is not feasible and in the presence of complex elbow injuries. Overstuffing of the radiocapitellar joint is a frequent technical fault and has significant adverse effects on elbow biomechanics. Modular design improves the surgeon’s ability to reconstruct the native joint. Two randomised controlled trials have shown improved clinical outcomes and lower complication rate following arthroplasty when compared to internal fixation. Conclusion: We have presented details regarding the treatment of various types of radial head fractures - further evidence, however, is still required to provide clarity over the role of these different management strategies.

Abstract
CASE We describe the case of a 66-year-old man who sustained a nondisplaced radial neck fracture and subsequently developed a symptomatic nonunion. After a period of unsuccessful conservative treatment, a radial head resection was performed. CONCLUSION Radial neck fractures, unlike their radial head counterparts, have a low rate of nonunion. Our patient's only positive risk factor was age, but he developed a nonunion. At the 2-year follow-up after excision of the radial head, there was a lack of proximal migration of the radius during axial loading, demonstrating a positive outcome without the need for replacement of the radial head.

Abstract
OBJECTIVE The best treatment for moderately displaced radial head fractures (Mason type II) still remains controversial. In cases of isolated fractures, there is no evidence that a fragment displacement of ≥ 2 mm gives poor results in conservatively treated fractures. PATIENTS AND METHODS We retrospectively reviewed 52 patients (31M, 21F) affected by an isolated Mason type II fracture, treated with a long arm cast for two weeks between 2008 and 2013. All patients had practiced sports before being injured. They were all either bicyclists, or baseball, boxers, basketball, rugby, tennis or football players. The mean follow-up was 36 months. Elbow and forearm range of motion were measured. The Mayo Elbow Performance Score, the Broberg and Morrey rating system and the Disabilities of the Arm, Shoulder and Hand Score (DASH score) were analyzed. Follow-up radiographs were examined for evidence of consolidation, late displacement, early arthritis and non-unions. RESULTS Flexion was slightly impaired in the injured limb when compared to the uninjured limb (137°± 6° versus 139°±5°) as were extension (-3°±6° versus 1°±4°, p < 0.05), supination (86°±6° versus 88°±3°), pronation (87°±4° versus 88°±6°) and valgus deviation (10°±4° versus 8°±3°, p < 0.05). 40 patients had no elbow complaints; 9 patients experienced occasional pain, 2 a mild instability of the elbow, and 4 a mild loss of grip strength. The DASH score was excellent in 48 patients (92.31%). In only 6 cases (11.53%) degenerative changes were greater in formerly injured elbows than in uninjured elbows. All patients returned to their previous sports activities. CONCLUSIONS Isolated Mason type II fractures can have a good or excellent mid-term functional outcome even when treated conservatively.

Abstract
BACKGROUND Radial head compression against the capitellum may cause concomitant fracture of the capitellum. The purpose of this study was to investigate if radial head fracture type is associated with a concomitant fracture of the capitellum. PATIENTS AND METHODS Data were identified from five area hospitals. We retrieved records of patients older than 18 years of age who underwent treatment for concomitant capitellum fracture and radial head fracture between January 2002 and January 2013. Patients with olecranon fractures or trochlea fractures were excluded. RESULTS A total of 10 patients with a radial head fracture and a concomitant capitellum fracture were included. Based on the operative reports, nine radial head fractures were classified as Hotchkiss modification of the Mason classification type II, and one was classified as type I. Based on the available radiographs and computed tomography, three capitellum fractures were type I, and seven were type II according to the Grantham classification. CONCLUSION Surgeons have to be alert to capitellar damage in case of a Hotchkiss type II radial head fracture. LEVEL OF EVIDENCE This is a level IV, therapeutic, retrospective study.

Abstract
BACKGROUND AND PURPOSE Elbow pain can originate from many sources yet have similar signs and symptoms, thereby presenting differential diagnostic challenges. The elbow is commonly injured, thus requiring all clinicians to possess excellent diagnostic skills. CASE DESCRIPTION A 24-year-old woman slipped and fell on her outstretched left hand, experiencing immediate elbow pain. The same day radiographs were deemed negative by her orthopedist, who referred her to physical therapy with the diagnoses of elbow sprain and contusion. Immediately after examining the patient, the physical therapist consulted with the referring orthopedist. The decision to consult was based on: the mechanism of injury, pain severity out of proportion to the referred diagnoses, significantly limited ROM, abnormal joint end feels, exquisite pain with tactile and tuning fork bony palpation, and positive elbow extension test. OUTCOMES The treating physical therapist shared the above-noted findings with the orthopedist, who overruled and recommended continuing the original prescription of non-steroidal anti-inflammatory medication and physical therapist treatment for four weeks. The physical therapist's updated plan of care at four weeks noted the patient's continued reports of pain, functional limitations, and disability. A magnetic resonance image (MRI) was then ordered, revealing a radial head fracture. DISCUSSION A thorough history and examination by the physical therapist led to clustering of signs and symptoms, allowing for the development of a differential diagnosis list which included occult radial head fracture. All clinicians should be prepared to screen for complex conditions. Timely diagnosis and improved outcomes for clinically complex patients are increasingly necessary in contemporary healthcare reimbursement models.

Abstract
BACKGROUND Recognition of patterns of traumatic elbow instability helps anticipate specific fracture characteristics and associated injuries. The objective of this study was to assess the association of fracture line distribution and location of displaced partial articular radial head fractures with specific patterns of traumatic elbow instability using fracture mapping techniques. METHODS Fracture line distribution and location of 66 acute displaced partial articular radial head fractures were identified using quantitative 3-dimensional computed tomography reconstructions that allowed reduction of fracture fragments and a standardized method to divide the radial head into quadrants with forearm in neutral position. Based on qualitative and quantitative assessment of fracture maps, the association between fracture characteristics of displaced partial articular radial head fractures and specific elbow fracture patterns was determined. RESULTS In partial articular radial head fractures, the highest fracture line intensity was located in the anterolateral quadrant near the center of the radial head. Fracture location corresponded with fracture line distribution; most fractures involved the anterolateral quadrant (n = 65; 98%), whereas parts of the posteromedial quadrant were involved in a minority of the fractures (n = 10; 15%). The association of fracture line distribution and location with overall fracture patterns of the elbow, as depicted on fracture maps, was not statistically significant. CONCLUSION Fracture maps demonstrated no association between fracture line distribution and location of displaced partial articular fractures of the radial head and overall specific patterns of traumatic elbow instability, suggesting a common fracture mechanism that involves the anterolateral part of the radial head in most patients.

Abstract
PURPOSE Exclusion or detection of non-displaced radial head fractures can be difficult in radiographs, because they might lack conclusive radiographic signs, such as fracture lines or distracted articular fragments. Based on the typical injury mechanism of a radial head fracture, causing the head to hit the capitulum and leading to a depression of the anterolateral border of the radial head, we hypothesized that even slight cortical irregularities in the transition zone of the radial neck and head result from that depression and may be a reliable radiographic sign of an underlying radial head fracture. Secondarily, we tested the null hypothesis that the lack of cortical irregularities is sufficient to exclude a fracture of the radial head. METHODS 84 patients with sets of anteroposterior and lateral radiographs of the elbow were identified from the database of a level 1 trauma center and divided into 2 groups. Group A was formed out of 42 patients with non-displaced radial head fractures, group B out of 42 patients without a history of previous elbow trauma, whose medical history also contained radiographic images. After the radial head was blackened, the transition zone of the radial neck and head was assessed by two attending orthopedic surgeons for presence of a cortical irregularity. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of cortical irregularity were calculated for the assessment of radial head fractures. The kappa measure of agreement was utilized to evaluate interrater agreement. RESULTS The specificity was 87.80 and 97.56 %, respectively, its sensitivity 86.04 and 75.61 %. A high NPV (85.71 %; 80.00 %) and PPV (96.88 %; 88.10 %.) were observed. The interrater agreement for the proposed diagnostic method was high, with a Cohen kappa score of 0.737 (p < 0.001). CONCLUSIONS A cortical irregularity in the transition zone of the radial neck and head seems to be a reliable radiographic sign of an underlying radial head fracture. The absence of the cortical irregularity can be used to correctly identify a non-fractured radial head.

Abstract
BACKGROUND The purpose of this study is to evaluate the role of radiographic and clinical exams in predicting screw penetration into the proximal radioulnar joint and ulnohumeral joint during open reduction and internal fixation of the radial head and proximal ulna. METHODS Olecranon and radial head plates were applied to 15 cadaveric elbows. Screws were assessed for intra-articular joint penetration using both clinical exam and radiographic evaluation. Clinical exam consisted of evaluation for crepitus. Radiographs demonstrating screws positioned near the joint surface were evaluated for penetration by 3 fellowship trained hand surgeons. Elbows were disarticulated and screw prominence was determined and recorded using standardized calipers. The ability of clinical and radiographic exams to correctly predict a breach in the articular surface was determined by calculating sensitivity, specificity, and predictive values. Consideration was given to screw position. RESULTS The sensitivity of crepitus was 81.1% for screws in the radial head plate and 72.6% for screws in the olecranon plate. The sensitivity of radiographs was 72.4% for the screws in the radial head plate and 55.0% for screws in the olecranon plate. Correct radiographic assessment of penetration varied but position o-2 on the olecranon plate consistently resulted in the lowest sensitivity of 30.3%. CONCLUSIONS The study evaluates sensitivity and specificity of clinical and radiographic means when assessing for articular penetration of screws during olecranon and radial head locking plate fixation. Certain screw locations are more difficult to evaluate than others and may go undetected by standard means of assessment used in a surgical setting.

Abstract
Background: Comminuted radial head fractures are often associated with secondary injuries and elbow instability. Objectives: The aim of this retrospective study was to evaluate how well the modular metallic radial head implant EVOLVE® prosthesis restores functional range of motion (ROM) and stability of the elbow in acute care. Patients and Methods: Eighty-five patients with comminuted radial head fractures and associated injuries received treatment with an EVOLVE® prosthesis between May 2001 and November 2009. Seventy-five patients were available for follow-up. On average, patients were followed for 41.5 months (33.0: 4.0 - 93.0). Outcome assessment was done on the basis of pain, ROM, strength, radiographic findings, and functional rating scores such as Broberg and Morrey, the Mayo elbow performance index (MEPI), and disabilities of the arm, shoulder and hand (DASH). Our study is currently the largest analysis of clinical outcome of a modular radial head replacement in the literature. Results: Overall, there were 2 (2.7%) Mason II fractures, 21 (28%) Mason III fractures, and 52 (69.3%) Mason IV fractures. Arbeitsgemeinschaft fur osteosynthesefragen (AO) classification was also determined. Of the 85 patients in our study, 75 were available for follow-up. Follow-up averaged 41.5 months (range, 4 - 93 months). Average scores for the cohort were as follows: Morrey, 85.7 (median 90.2; range 44.4 - 100); MEPI, 83.3 (85.0; 40.0 - 100); and DASH 26.1 points (22.5; 0.0 - 75.8). Mean flexion/extension in the affected joint was 125.7°/16.5°/0° in comparison to the noninjured side 138.5°/0°/1.2°. Mean pronation/supination was 70.5°/0°/67.1° in comparison to the noninjured side 83.6°/0°/84.3°. Handgrip strength of the injured compared to the non-injured arm was 78.8%. The following complications were also documented: 58 patients had periprosthetic radioluceny shown to be neither clinically significant nor relevant according to evaluated scores; 26 patients had moderate or severe periarticular ossification, and scored substantially worse according to MEPI and Morrey. Four patients required revisional surgery due to loosening of the prosthesis and chronic pain. In addition, one patient required a neurolysis of the ulnaris nerve, one developed a neobursa, and one had extensive swelling and blistering. The time interval between injury and treatment appeared to have an effect on results. Thirty-five patients were treated within the first 5 days after accident and showed better results than the 40 patients who were treated after 5 days. Conclusions: Comminuted radial head fractures with elbow instability can be treated well with a modular radial head prosthesis, which restores stability in acute treatment. The modular radial head arthroplasty used in this study showed promising findings in short to midterm results.

Abstract
BACKGROUND Intra-articular (IARH) and extra-articular (EARH) radial head fractures in skeletally immature patients are rare injuries that have not been well studied. The objective of this study was to investigate the rate of complications associated with IARH fractures relative to EARH fractures in pediatric patients treated at a tertiary referral children's hospital. METHODS With IRB approval, Current-Procedural Terminology codes were used to identify all patients who underwent management of radial head and/or neck fractures between 2005 and 2012. A retrospective chart review was used to collect variables related to: demographics, fracture type, treatment method(s), complications, need for physical/occupational therapy, and the need for subsequent surgery. Mid-P exact tests and logistic regression analyses were used to compare differences in the incidence of complications, need for physical therapy (PT), and need for revision surgery between the IARH and EARH fracture groups. RESULTS Among the 311 patients included in the cohort, 12 (3.86%) were affected by IARH fractures and 299 (96.14%) were affected by EARH fractures. The mean age at the time of injury was 11.46 (±3.09) years and 8.32 (±3.31) years in the IARH and EARH group, respectively. The estimated incidence of complications was significantly (P<0.0001) higher in the IARH group (50 per 100) compared with the EARH group (1.34 per 100). A significantly (P<0.0001) greater proportion of the subjects with IARH fractures also required revision surgery (25% IARH vs. 0% EARH) and PT (50% IARH vs. 19.59% EARH). CONCLUSIONS Compared with EARH fractures, IARH fractures were associated with a significantly higher rate of complications, greater need for PT, and greater need for surgical intervention. The significant complication rate associated with pediatric IARH fractures necessitates an increased awareness of this fracture pattern and prompt, aggressive diagnostic and treatment modalities. LEVEL OF EVIDENCE Therapeutic studies: Level III.
