Abstract
PURPOSE Coronal shear fractures of the distal humerus involving the capitellum and trochlea are rare injuries. Internal fixation with headless compression screws provides a stable construct facilitating early mobilisation. Our study aimed to identify the key determinants of both radiological and functional outcomes of patients with distal humerus coronal shear fractures treated with internal fixation. METHODS A retrospective analysis of 61 patients with distal humerus coronal shear fractures who were treated surgically was done. Demographics, fracture morphology, time to surgery, operative details such as surgical approach and implant used, quality of reduction, time to union, and associated complications from hospital records. Radiological outcomes were assessed using plain radiographs, and the functional outcomes were by Oxford Elbow Score (OES) and Mayo Elbow Performance Index (MEPI). RESULTS Patients with anatomical reduction of the fracture had better functional outcomes and range of motion. The presence of posterior comminution of capitellum resulted in poorer outcomes (p = 0.03). Delayed presentation did not alter the outcome when the anatomical reduction was achieved. Myositis ossificans was noted in nine patients and non-union in five patients. Two patients developed avascular necrosis of the capitellum and arthritis of the elbow joint. CONCLUSION Anatomical reduction and posterior comminution are the two key determinants of the functional outcome in these coronal shear fractures of the distal humerus. Early mobilisation following a stable fixation is crucial in achieving a good outcome.

Abstract
Osteochondritis dissecans of the capitellum is debilitating and is a potentially sports career-ending injury in a young and athletic population. Osteochondritis dissecans typically occurs in patients between the ages of 10 and 24 years, and boys are more commonly affected than girls. Conventional radiographs have low diagnostic accuracy, and magnetic resonance imaging (with or without contrast) or computed tomography may aid in accurate diagnosis. The primary indication for non-operative treatment is the presence of an intact cartilage cap on magnetic resonance imaging, indicating a "stable lesion." However, if operative treatment is necessary, various surgical procedures are available when operative treatment for an osteochondritis dissecans of the capitellum is considered, including open or arthroscopic removal of loose bodies, with or without microfracturing, fragment fixation, osteochondral autograft transplantation, and osteochondral allograft transplantation. The decision-making process for selecting the appropriate treatment considers factors such as the patient's characteristics, functional limitations, and lesion morphology.

Early Arthroscopic Debridement May Be More Cost-Effective Than Nonoperative Management for Symptomatic Osteochondritis Dissecans Lesions of the Capitellum. Arthrosc Sports Med Rehabil 2024; 6:100836. [PMID: 38162589 PMCID: PMC10756960 DOI: 10.1016/j.asmr.2023.100836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 10/31/2023] [Indexed: 01/03/2024] Open
Abstract
Purpose To compare the cost-effectiveness of an initial trial of nonoperative treatment to that of early arthroscopic debridement for stable osteochondritis dissecans (OCD) lesions of the capitellum. Methods A Markov Chain Monte Carlo probabilistic model was developed to evaluate the outcomes and costs of 1,000 simulated patients undergoing nonoperative management versus early arthroscopic debridement for stable OCD lesions of the capitellum. Health utility values, treatment success rates, and transition probabilities were derived from the published literature. Costs were determined on the basis of the typical patient undergoing each treatment strategy at our institution. Outcome measures included costs, quality-adjusted life-years (QALYs), and the incremental cost-effectiveness ratio (ICER). Results Mean total costs resulting from nonoperative management and early arthroscopic debridement were $5,330 and $21,672, respectively. On average, early arthroscopic debridement produced an additional 0.64 QALYS, resulting in an ICER of $25,245/QALY, which falls well below the widely accepted $50,000 willingness-to-pay (WTP) threshold. Overall, early arthroscopic debridement was determined to be the preferred cost-effective strategy in 69% of patients included in the microsimulation model. Conclusion Results of the Monte Carlo microsimulation and probabilistic sensitivity analysis demonstrated early arthroscopic debridement to be a cost-effective treatment strategy for the majority of stable OCD lesions of the capitellum. Although early arthroscopic debridement was associated with higher total costs, the increase in QALYS that resulted from early surgery was enough to justify the cost difference based on an ICER substantially below the $50,000 WTP threshold.

Abstract
Background An olecranon stress fracture (OSF) is a rare injury most commonly seen in high-level overhead throwing athletes with no clear consensus on surgical treatment. The most common surgical treatment described in the literature is cannulated screw fixation but there have been high rates of reported hardware irritation and need for subsequent hardware removal. Hypothesis/Purpose This study describes a novel surgical technique in the treatment of OSFs in high-level throwing athletes using retrograde headless compression screws. We hypothesized that patients would have excellent outcomes and decreased rates of hardware irritation postoperatively. Methods A retrospective review of competitive-level throwing athletes who sustained OSFs that were treated operatively using a novel technique using retrograde cannulated headless compression screws to avoid disruption of the triceps tendon. Postoperative outcome measures obtained included the Disabilities of the Arm, Shoulder and Hand score, Mayo Elbow Performance Score, Simple Elbow Test score, Single Assessment Numerical Evaluation score, Visual Analog Scale, arch of motion, and time to return to sport as well as level returned to. Radiographs were obtained routinely at 2-week, 6-week, 12-week, 6-month, 1-year, and 2-year follow-up. Results Five of 5 patients who met inclusion criteria were available for final follow-up. Mean age at time of surgery was 20 years (range 17-24). Mean follow-up was 17 months (range 4-33). All patients were baseball players, 4 of which were pitchers and 1 position player. All patients were able to return to sport at the same level or higher at a mean of 5.8 months (range 3-8). Postoperatively, mean arch of motion was 138°, Visual Analog Scale score was 0, Single Assessment Numerical Evaluation score was 90, Disabilities of the Arm, Shoulder and Hand score was 2.0, Mayo Elbow Performance Score was 100, and Simple Elbow Test score was 12. There was no incidence of hardware removal. Conclusion This study presents a novel surgical technique in the treatment of OSFs in high-level throwing athletes. The results presented demonstrate that this technique is safe and effective for getting athletes back to play quickly without any complications of hardware irritation which has previously shown to be a significant problem in prior literature.

Abstract
INTRODUCTION Onset of radial neck osteolysis (RNO) has been reported after radial head replacement (RHR), but data are sparse regarding impact and risk factors. We therefore conducted a retrospective study, 1) to quantify RNO after RHR, 2) to assess clinical and radiological impact, and 3) to identify risk factors. HYPOTHESIS RNO prevalence is high, but functional impact is limited. MATERIAL AND METHOD A single-center retrospective study included all patients undergoing RHR for acute radial head fracture between 2008 and 2017: 53 patients, with a mean age of 53.8±15.7 years [range, 21-85 years]. At a minimum 2 years' follow-up, patients were assessed clinically on joint range of motion and Mayo Elbow Performance Score (MEPS) and radiologically on standard radiographs. Associations between RNO and various parameters were assessed. RESULTS At a mean 46.7±19.8 months' follow-up [range, 24-84 months], RNO was found in 54.7% of cases (29/53), with mean 4.0 ±2.8mm distal extension [range, 1.2-13.4mm], corresponding to 13.4±7.3% of stem height [range, 2.7-27.7%]. RNO at last follow-up was not significantly associated with reduced flexion-extension (121.9° versus 114.0°; p=0.11), pronation-supination (152.6° versus 138.3°; p=0.25) or MEPS (84.7 versus 84.8; p=0.97), or with higher rates of postoperative complications (11/29 (37.9%) versus 7/24 (29.2%); p=0.782) or surgical revision (11/29 (37.9%) versus 10/24 (41.7%); p=0.503). RNO was significantly associated with cementless fixation (19/29 (65.5%) versus 7/24 (29.2%); p=0.01), unipolar prosthesis (21/29 (72.4%) versus 7/24 (29.2%); p=0.002), high filling-ratio, whether proximal (88% versus 77%; p=0.002), middle (84% versus 75%; p=0.007) or distal (69% versus 59%; p=0.032), and shorter radial stem (33.2mm versus 46.3mm; p=0.011). No demographic parameters showed significant association with RNO at last follow-up. CONCLUSION RNO was frequent after RHR, but without clinical or radiological impact in the present series. The risk factors identified here argue for involvement of stress shielding. LEVEL OF EVIDENCE IV, cohort study.

Abstract
INTRODUCTION AND IMPORTANCE Coronal shear fractures of the distal humerus are rare and are expected to have a high incidence of avascular necrosis (AVN) due to the avascular nature of the capitellar bone fragment and limited soft tissue attachment. However, according to the literature published thus far, AVN is infrequently reported, and some studies suggest that it does not have a significant impact on clinical outcomes. CASE PRESENTATION Two female patients, one aged 72 and the other 70, presented with coronal shear fractures of distal humerus. Both patients were diagnosed with AVN of the capitellum 7 and 10 months after undergoing open reduction and internal fixation. One patient underwent hardware removal, while the other patient declined due to the absence of discomfort. However, at their final follow-up, both patients exhibited good clinical results. CLINICAL DISCUSSION The occurrence of AVN may be related to the severity of the initial injury, including posterior comminution. While some studies suggest that AVN of the capitellum may not affect clinical outcomes, hardware removal may be required in cases where there is intra-articular protrusion of the hardware. CONCLUSION Although AVN is a rare occurrence, even when it does occur, it may not significantly affect clinical outcomes. In this study, AVN may be associated with initial injury severity, and surgical treatment may make it possible to develop AVN. Moreover, considering the timing of the occurrence of AVN, it is believed that a close follow-up of more than one year will be required.

Abstract
Coronal plane articular shear fractures of the distal humerus are a rare injury, comprising 6% of distal humerus fractures. The fracture can be easily missed on initial radiographs; therefore, a high index of suspicion is warranted. Radiographically obvious fractures are often more complex than initially appreciated, with plain radiographs often underestimating the extent of posterior comminution and trochlear involvement. Associated bony and ligamentous injuries are common. Anatomic reduction and internal fixation of displaced fractures is the standard of care because poor results have been described with nonsurgical treatment. However, the regional anatomy and the often-limited bone stock can make open reduction and internal fixation challenging. The lateral approach, with headless compression screws placed from anterior to posterior, is commonly used for simpler fracture patterns, but exposure and fixation of trochlea extension can be difficult. In the absence of posterior comminution, the anterolateral approach can enhance trochlea exposure and allow for a better trajectory for screw placement. Posterior comminution often requires locking plate fixation. Better results and lower complication rates have been reported for fractures with less fragmentation of the articular surface and those without posterior comminution. Contracture and symptomatic implants are the most common reasons for revision surgery.

Abstract
Background In a simple isolated capitellar/trochlear fracture without extensive posterior comminution, arthroscopic reduction and internal fixation (ARIF) can provide an alternative option to open reduction internal fixation. The purpose of this retrospective case series was to report on the technique and outcomes of arthroscopic reduction and internal fixation of capitellar/trochlear fractures. Methods All patients that underwent ARIF at a single upper extremity referral centre in the last twenty years were reviewed. Patient demographics, preoperative, intraoperative, and postoperative records were obtained through chart review and telephone followup. Results Ten cases of ARIF were identified over a twenty year period performed by two surgeons. The average age of patients was 37 years (17-63 years), with nine females and one male. With an average followup of eight years, nine of ten patients had a mean range of motion from 0 to 142 degrees. Their average MEPI and PREE score were 93 ± 7 and 8 ± 14, respectively. Four patients had focal cartilage collapse with three that required a reoperation. There were no infections, nonunions, or arthroscopy related complications. Conclusion ARIF offers an alternative to ORIF for capitellar/trochlear fractures producing good results while providing better visualization of the fracture reduction and minimizing soft tissue dissection.

Osteochondritis Dissecans of the Capitellum of the Elbow: Improved Outcomes in Surgically Treated Versus Nonoperatively Treated Patients at Long-Term Follow-up. Arthrosc Sports Med Rehabil 2023; 5:e435-e444. [PMID: 37101861 PMCID: PMC10123431 DOI: 10.1016/j.asmr.2023.01.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Accepted: 01/05/2023] [Indexed: 03/21/2023] Open
Abstract
Purpose To (1) report the long-term outcomes associated with both operative and nonoperative management of capitellar osteochondritis dissecans (OCD), (2) identify factors associated with failure of nonoperative management, and (3) determine whether delay in surgery affects final outcomes. Methods All patients who received a diagnosis of capitellar OCD from 1995-2020 within a geographic cohort were included. Medical records, imaging studies, and operative reports were manually reviewed to record demographic data, treatment strategies, and outcomes. The cohort was divided into 3 groups: (1) nonoperative management, (2) early surgery, and (3) delayed surgery. Delayed surgery (surgery ≥6 months after symptom onset) was considered failure of nonoperative management. Results Fifty elbows with a mean follow-up period of 10.5 years (median, 10.3 years; range, 1-25 years) were studied. Of these, 7 (14%) were definitively treated nonoperatively, 16 (32%) underwent delayed surgery after at least 6 months of failed nonoperative treatment, and 27 (54%) underwent early surgical intervention. When compared with nonoperative management, surgical management resulted in superior Mayo Elbow Performance Index pain scores (40.1 vs 33, P = .04), fewer mechanical symptoms (9% vs 50%, P < .01), and better elbow flexion (141° vs 131°, P = .01) at long-term follow-up. Older patients trended toward increased failure of nonoperative management (P = .06). The presence of an intra-articular loose body predicted failure of nonoperative management (P = .01; odds ratio, 13). Plain radiography and magnetic resonance imaging had poor sensitivities for identifying loose bodies (27% and 40%, respectively). Differences in outcomes after early versus delayed surgical management were not observed. Conclusions Nonoperative management of capitellar OCD failed 70% of the time. Elbows that did not undergo surgery had slightly more symptoms and decreased functional outcomes compared with those treated surgically. The greatest predictors of failure of nonoperative treatment were older age and presence of a loose body; however, an initial trial of nonoperative treatment did not adversely impact the success of future surgery. Level of Evidence Level III, retrospective cohort study.

Does proximal versus distal injury location of the medial ulnar collateral ligament of the elbow differentially impact elbow stability? An ultrasound-guided and robot-assisted biomechanical study. J Shoulder Elbow Surg 2022; 31:1993-2000.

Abstract
BACKGROUND The location (proximal vs. distal) of elbow medial ulnar collateral ligament (MUCL) tears impacts clinical outcomes of nonoperative treatment. The purposes of our study were to (1) determine whether selective releases of the MUCL could be performed under ultrasound (US) guidance without disrupting overlying soft tissues, (2) assess the difference in medial elbow stability for proximal and distal releases of the MUCL using stress US and a robotic testing device, and (3) elucidate the flexion angle that resulted in the greatest amount of medial elbow laxity after MUCL injury. METHODS Sixteen paired, fresh-frozen elbow specimens were used. Valgus laxity was evaluated with both US and robotic-assisted measurements before and after selective MUCL releases. A percutaneous US-guided technique was used to perform proximal MUCL releases in 8 elbows and to perform distal MUCL releases in their matched pairs. The robot was used to determine the elbow flexion angle at which the maximum valgus displacement occurred for both proximally and distally released specimens. Open dissection was then performed to assess the accuracy of the percutaneous releases. RESULTS Percutaneous US-guided releases were successfully performed in 15 of 16 specimens. The proximal release resulted in greater valgus angle displacement (11° ± 2°) than the distal release (8° ± 2°) between flexion angles of 30° and 70° (P < .0001 at 30°, P < .0001 at 40°, P = .001 at 50°, P = .005 at 60°, and P = .020 at 70°). Valgus displacement between release locations did not reach the level of statistical significance between 80° and 120° (P = .051 at 80°, P = .131 at 90°, P = .245 at 100°, P = .400 at 110°, and P = .532 at 120°). When we compared the values for the mean increase in US delta gap (stressed - supported state) from before to after MUCL release, the proximally released elbows had larger increases than the distally released elbows (5.0 mm proximal vs. 3.7 mm distal, P = .032). After MUCL release, maximum mean valgus displacement occurred at 49° of flexion. CONCLUSIONS US-guided selective releases of the MUCL can be performed reliably without violating the overlying musculature. Valgus instability is not of greater magnitude for distal releases when compared with proximal releases. This findings suggests there must be alternative factors to explain the difference in clinical prognosis between distal and proximal tears. The observed flexion angle for maximum valgus laxity could have important implications for elbow positioning during US or fluoroscopic stress examination, as well as surgical repair or reconstruction of the MUCL.

Abstract
Background Elbow trochlea osteochondritis dissecans (OCD) is rare with limited information on it. The aim of this systematic review is to assess the published evidence on trochlea OCD in terms of presenting symptoms, location of OCD and outcome of management in adolescent patients. Patient & Methods A review of the online databases MEDLINE and Embase was conducted according to PRISMA guidelines. The review was registered prospectively in the PROSPERO database. Clinical studies reporting on any aspect of trochlea OCD management were eligible for inclusion and appraised using the Methodological Index for Non-Randomized Studies (MINORS) tool. Results 16 studies were eligible for inclusion with a total of 75 elbow. Mean age was 14 years (8-19) of which 46 were males. The main presenting symptoms were pain (95%). Non-operative care was reported in 86% of elbows with resolution of symptoms in 76%. Surgical management was described in 14%. There were equal number of arthroscopic and open procedures. 94% had successfully resolution of symptoms post-operatively. Conclusion Elbow trochlea OCD is a rare pathology and one that can be managed non-operatively in the majority of cases with good resolution of symptoms. However, if this fails, operative options are available with excellent results reported. Level of evidence Level IV, Systematic review.

Abstract
Purpose This is a retrospective cohort study of type C distal humeral fractures (AO classification system) aimed at evaluating the effectiveness of current operative treatment options. Materials and methods Thirty-seven patients with type C distal humeral fractures, treated operatively from January 2002 to September 2016, were retrospectively studied. Thirty-two were eligible for inclusion. Patients were treated by open reduction using the posterior approach, olecranon osteotomy and parallel-plate two-column internal fixation. Patients were evaluated for fracture healing, functional outcomes and complications (infection, ulnar neuropathy, heterotopic ossification and need for implant removal). Restoration of the normal anatomy was defined by measuring carrying angle, posterior angulation and intercondylar distance of distal humerus. Results The mean follow-up time was 8.7 years [range 2–15.5 years, standard deviation (SD) = 3.96]. Mean time to fracture union was 8 weeks for 29 patients (90.6%) (range, 6–10 weeks). In nine cases, there was malunion of varied importance (28.1%). There was one case with postoperative ulnar neuropathy and one case with deep infection. The mean Disabilities of the Arm, Shoulder and Hand (DASH) score and mean Mayo Elbow Performance Score (MEPS) were 20 (range 0–49) and 83.3 (range 25–100), respectively. Conclusion In complex distal humerus fractures, the posterior approach with olecranon osteotomy and parallel plating of two columns, after anatomic reconstruction of the articular segment, is a prerequisite for successful elbow function.

J Hand Surg Am 2022:S0363-5023(21)00801-7. [PMID: 35153076 DOI: 10.1016/j.jhsa.2021.12.007] [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: 03/03/2021] [Revised: 10/21/2021] [Accepted: 12/02/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to compare, using a cadaveric model, the biomechanical properties of headless compression screws (HCSs) and HCSs augmented with a buttress plate (BP) in capitellar fractures. METHODS Twenty pairs of fresh-frozen humeri (mean age, 46.3 years; range, 33-58 years) were used. The soft tissue was removed, and a Dubberley type IA capitellar fracture was created. One specimen in each pair was randomly assigned to receive either two 2.5-mm HCSs (HCS group) or two 2.5-mm HCSs augmented with an anterior 2.4-mm BP (HCS + BP group). This resulted in a similar distribution of the left and right humeri between the groups. Cyclic loading was performed, and displacement of the capitellum at 50, 100, 250, 500, 1,000, and 2,000 cycles was assessed using a motion capture system. This was followed by load-to-failure testing, wherein the load at a displacement of 1 and 2 mm was recorded. Failure was defined as 2-mm displacement. RESULTS During cyclic loading, there were no significant differences in the displacement between the HCS and HCS + BP groups at any of the assessed cycles. During load-to-failure testing, no significant strength differences were observed in the load at 1-mm displacement between the HCS (mean: 449.8 N, 95% CI: 283.6-616.0) and HCS + BP groups (mean: 606.2 N, 95% CI: 476.4-736.0). However, a significantly smaller load resulted in a 2-mm displacement of the fragment in the HCS group (mean: 668.8 N, 95% CI: 414.3-923.2) compared with the HCS + BP group (mean: 977.5 N, 95% CI: 794.1-1,161.0). CONCLUSIONS Anterior, low-profile buttress plating in addition to HCSs results in a significantly higher load to failure compared with HCSs alone in a biomechanical Dubberley type IA capitellar fracture model. CLINICAL RELEVANCE The addition of an anterior BP may be considered to improve initial stability in select cases such as osteoporotic patients or when the posterolateral column is frail.

Abstract
A Monteggia fracture-dislocation involves a proximal one-third of the ulna fracture with a concomitant dislocation of the radial head proximally at the elbow. This fracture and dislocation often results from a fall on the outstretched hand (FOOSH) low-energy mechanism of injury. One must have a high index of suspicion with any ulnar fractures to look for a radial head dislocation so that the dislocation component is not missed. These injuries often require early orthopedic intervention. Any delays in treatment can lead to poor long-term outcomes including chronic valgus instability and radiocapitellar osteoarthrosis.

Abstract
Coronal shear fractures of the distal humerus are rare, frequently comminuted, and are without consensus for treatment. The aim of this paper is to review the current concepts on the diagnosis, classification, treatment options, surgical approaches, and complications of capitellar and trochlear fractures. Computed Tomography (CT) scans, along with the Dubberley classification, are extremely helpful in the decision-making process. Most of the fractures necessitate open reduction and internal fixation, although elbow arthroplasty is an option for comminuted fractures in the elderly low-demand patient. Stiffness is the most common complication after fixation, although reoperation is infrequent.

Abstract
PURPOSE Osteochondritis dissecans (OCD) of the capitellum is often treated by marrow stimulation techniques with good long-term outcomes. Magnetic resonance imaging (MRI) can be used to characterize the healing of cartilage repair tissue. However, no formal system exists for assessment of cartilage healing after marrow stimulation in capitellar OCD. The aims of this study were to describe the postoperative MRI appearance of capitellar repair cartilage after debridement and marrow stimulation for capitellar OCD and assess differences between symptomatic and asymptomatic patients. METHODS This was a retrospective study of patients with capitellar OCD who underwent arthroscopic debridement and marrow stimulation and had a postoperative MRI to assess healing. The classification system developed by Marlovits and colleagues (Magnetic Resonance Observation of Cartilage Repair Tissue) was used to quantitatively profile the cartilage repair tissue in comparison to adjacent "normal" cartilage. Study participants completed an online survey to correlate outcomes with cartilage appearance. RESULTS Eleven patients who underwent MRI for routine evaluation (asymptomatic), and 18 who underwent MRI for symptoms were identified. Overall, 59% of defects were completely filled, and in 83%, the cartilage surface had ulcerations or fibrillations. The cartilage variables were similar between symptomatic and asymptomatic patients. Capitellar subchondral bone edema was observed on the MRI of every patient who underwent a reoperation and was present in only 62% of those who did not. Clinical scores did not correlate with MRI cartilage findings, but the small sample size limited conclusions regarding clinical outcomes related to postoperative cartilage features seen on MRI. CONCLUSIONS This detailed assessment of cartilage appearance by MRI after marrow stimulation for capitellar OCD demonstrated that incomplete cartilage fill was common in both symptomatic and asymptomatic patients. Those requiring a second surgery were more likely to demonstrate subchondral bone edema. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic IV.

Abstract
PURPOSE Outcome measures that lack sensitivity for the detection of clinical changes early after surgery for capitellar osteochondritis dissecans (OCD) make it difficult to determine the optimal treatment for these defects. We sought to evaluate the early responsiveness of patient-reported outcomes measurement information system (PROMIS) scores in a cohort of patients operatively treated for capitellar OCD. METHODS Four PROMIS questionnaires (mobility, upper extremity [UE], pain interference, and peer relations) were electronically administered to patients treated for capitellar OCD at a single tertiary academic medical center between January 1, 2015, and July 1, 2018. The questionnaires were administered at the initial preoperative outpatient clinic visit as well as at the 2-week, 6-week, and final return-to-play (RTP) visits. RESULTS Twenty-nine patients (31 elbows, mean age 12.9 years) with available preoperative and postoperative PROMIS data were included. The mean final follow-up period was 26 weeks. Compared with that before surgery, there was a significant improvement in the mobility, pain interference, and UE scores at 6 weeks following surgery. The scores improved most significantly by 6 weeks, reached a relative plateau, and remained significantly improved through the RTP visit thereafter. Patients with preoperative, intra-articular loose bodies scored significantly better than those without them during the 6-week and RTP visits. Patients with lesions >1 cm2, compared with those with lesions ≤1 cm2, demonstrated greater improvement in the UE scores during the RTP visit. CONCLUSIONS In patients undergoing operative treatment for capitellar OCD, a significant improvement in the PROMIS domains of mobility, pain interference, and UE can be expected early in the postoperative period, with majority of patients reaching their greatest improvement in scores by 6 weeks following surgery. CLINICAL RELEVANCE This is important information for preoperative counseling. In addition, this information is helpful in confirming that PROMIS scores are responsive in the detection of changes in outcomes during the early postoperative period in this population.

Abstract
Fractures of the capitellum and trochlea are uncommon fractures of the elbow and can be challenging to treat due to their size, location, and articular nature. Because of their intra-articular nature and predilection toward displacement, these fractures are typically treated operatively. Furthermore, capitellum fractures have high rates of associated injuries, including radial head fractures or lateral collateral ligament injury in ~30% to 60% of patients. In addition to open reduction internal fixation, operative options include fragment excision, arthroscopic assisted reduction and fixation, and elbow arthroplasty. In this article, we undertake a comprehensive literature review of capitellum fractures of the distal humerus, in an attempt to summarize the existing body of evidence and propose areas of future study.

Abstract
Objective The aim of this study is to analyze the efficacy of open reduction and Herbert screw fixation for coronal fractures of the capitellum via the anterior approach in adolescents. Methods We retrospectively analyzed the clinical and imaging data of 15 adolescents with capitellar fractures who were admitted to our hospital from May 2014 to May 2019. The fracture was reduced through the cubital crease incision via the anterior approach and was internally fixated with Herbert screws. A follow-up was conducted after the operation to examine fracture healing and elbow function. The postoperative functional recovery of patients was evaluated with the Mayo Elbow Performance index (MEPI) and the Broberg-Morrey rating system. Results Patients underwent surgery 3.7 days after injury on average. Intraoperative fracture reduction was satisfactory. No vascular injury or nerve injury occurred. Bony union occurred in an average of 6 weeks after the operation. All adolescents completed a 12- to 36-month follow-up. At the last follow-up, the Mayo Elbow Performance index was considered excellent in 12 patients and good in three patients. The Broberg-Morrey score was considered excellent in 12 patients, good in two patients, and fair in one patient. Conclusion Open reduction with Herbert screw fixation via the anterior approach is a feasible surgical method for the treatment of coronal fractures of the capitellum in adolescents.

Abstract
➤ Osteochondritis dissecans occurs most frequently in the active pediatric and young adult populations, commonly affecting the knee, elbow, or ankle, and may lead to premature osteoarthritis. ➤ While generally considered an idiopathic phenomenon, various etiopathogenetic theories are being investigated, including local ischemia, aberrant endochondral ossification of the secondary subarticular physis, repetitive microtrauma, and genetic predisposition. ➤ Diagnosis is based on the history, physical examination, radiography, and advanced imaging, with elbow ultrasonography and novel magnetic resonance imaging protocols potentially enabling early detection and in-depth staging. ➤ Treatment largely depends on skeletal maturity and lesion stability, defined by the presence or absence of articular cartilage fracture and subchondral bone separation, as determined by imaging and arthroscopy, and is typically nonoperative for stable lesions in skeletally immature patients and operative for those who have had failure of conservative management or have unstable lesions. ➤ Clinical practice guidelines have been limited by a paucity of high-level evidence, but a multicenter effort is ongoing to develop accurate and reliable classification systems and multimodal decision-making algorithms with prognostic value.

Abstract
PURPOSE Magnetic resonance imaging (MRI) is a helpful tool in the evaluation of osteochondritis dissecans (OCD) of the humeral capitellum. The relationship between MRI appearance and clinically relevant intraoperative findings is incompletely understood. The goal of this study was to evaluate capitellar OCD lesions via preoperative MRI and to determine its accuracy in predicting lesion characteristics including lesion size and capitellar lateral wall integrity. METHODS Patients surgically treated for capitellar OCD between January 2010 and June 2018 were reviewed. Preoperative MRI images were assessed by a musculoskeletal radiologist with documentation of lesion size, location, violation of the lateral wall, and stage, in accordance with previously established criteria. These data were compared with intraoperative findings. Involvement of the lateral wall of the capitellum was defined using 2 methods: (1) subchondral edema or articular cartilage disruption in the lateral third of the capitellum (lateral third method) or (2) disruption of the proximal-distal subchondral line along the lateral border of the capitellum descending vertically before the subchondral bone turns horizontally to form the radiocapitellar articulation (capitellar lateral wall sign method). Diagnostic test characteristics were compared for both methods. RESULTS We reviewed the preoperative MRIs of 33 elbows with capitellar OCD and found no significant difference in mean lesion size between preoperative MRI (1.12 cm2) and intraoperative measurement (1.08 cm2). For detection of lateral wall integrity, preoperative MRI evaluation using the capitellar lateral wall sign method had an accuracy of 93%, sensitivity of 80%, specificity of 96%, positive predictive value of 80%, and negative predictive value of 96%. CONCLUSIONS Preoperative MRI is a valid predictor of lesion size. The capitellar lateral wall sign method is highly accurate in the identification of lateral wall involvement, which may influence preoperative planning. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic II.

Comparison of double screw fixation versus tension-band fixation after olecranon osteotomy for complex distal humerus fractures. Orthop Traumatol Surg Res 2021; 107:102641. [PMID: 33129752 DOI: 10.1016/j.otsr.2020.02.022] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 01/23/2020] [Accepted: 02/18/2020] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Supra- and intercondylar elbow fractures are surgically challenging given the intra-articular comminution. Various surgical approaches have been described. Among these-olecranon osteotomy-provides optimal joint exposure but is associated with several complications. Tension band wiring (TBW) is the most commonly used fixation method. We hypothesized that double screw fixation would lead to fewer surgical revisions than TBW (all causes included) after olecranon osteotomy. METHODS We carried out a single-center retrospective study of 39 patients, treated between January 2007 and April 2016, for a supra- or intercondylar elbow fracture using the transolecranon exposure. There were 34 type C fractures (13 C1, 6 C2 and 15 C3), 3 type B fractures and 2 type A fractures, based on the AO classification. Fourteen patients received double screw fixation and 25 received TBW. The primary outcome measure was the number of surgical revisions, regardless of cause. Secondary outcome measures were the number of surgical revisions for olecranon nonunion, fixation failure or fixation device removal due to pain. RESULTS There were significantly more surgical revisions in the TBW group than in the double screw fixation group: 3 (21%) versus 14 (56%) (p=0.049, Fisher test). The three main reasons for revision in the TBW and double screw fixation groups were removal of the fixation device due to soft tissue impingement (11 [44%] versus 2 [14%]; p=0.08), failure of the olecranon fixation (6 [24%] versus 1 [7%] p=0.38), and olecranon nonunion (4 [16%] versus 0 [0%] p=0.27). DISCUSSION There are no published studies on the outcomes of this surgical technique. The posterior transolecranon approach provides the best exposure at the elbow joint. TBW fixation is associated with multiple complications. Double screw fixation for olecranon fractures yields good clinical and radiological outcomes. CONCLUSION Based on our findings, double screw fixation of the olecranon results in fewer surgical revisions (all causes combined) than TBW in supra- and intercondylar elbow fractures operated by a transolecranon approach.

Abstract
OBJECTIVE Tennis is a popular sport with high levels of participation. This article aims to describe how upper extremity overuse injuries occur in relation to tennis biomechanics and to review their imaging characteristics and implications for management. In particular, we will review the imaging patterns of internal impingement, scapular dyskinesis, lateral and medial epicondylitis, ulnar collateral ligament insufficiency, valgus extension overload, capitellar osteochondritis dissecans, extensor carpi ulnaris tendinosis and instability, tenosynovitis, triangular fibrocartilage complex injuries, and carpal stress injuries. CONCLUSION Tennis is a complex and physically demanding sport with a wide range of associated injuries. Repetitive overloading commonly leads to injuries of the upper extremity. An understanding of the underlying mechanisms of injury and knowledge of these injury patterns will aid the radiologist in generating the correct diagnosis in both the professional and recreational tennis athlete.

Abstract
İntroduction: Avascular necrosis of humeral trochlea is a very rare condition and was described by Hegemann in 1957. We reported two cases of avascular necrosis of humeral trochlea and also performed a literature review of the reported cases. We expect that this case report will assist clinicians to make timely diagnosis when encountering similar clinical scenarios. MATERIALS AND METHODS We presented 11-year-old and 14 year-old two cases with avascular necrosis of humeral trochlea. The common etiology was idiopathic because there were no recent trauma history and sports activity. Also there was no history of drug use. We discussed the clinical and radiologic findings of these cases. RESULTS These cases were diagnosed as Hegemann's disease with clinical and radiologic outcomes. We found the etiology of both two cases is idiopathic. Both two cases were boys and teenagers. The number of previously reported cases in the literature is limited to 63. In our study there was a lateral crest in one of our two cases and a posteromedial involvement in another. The radiograph of two trochlea of these two cases showed irregularity and granular appearance. In our case, heterogeneous signal changes and irregularities are accompanied by hypointense changes on T1-weighted images. Also hyperintense changes on proton density sequences were detected. CONCLUSION Radiological evaluation plays an important role in the diagnosis and evaluation of response to treatment in avascular necrosis of the humeral trochlea. Avascular necrosis should be one of the differential of lesions involving the trochlea. Recognition of avascular necrosis in the trochlea may prevent unnecessary biopsy.

Abstract
Gartland type III posterolateral (IIIB) supracondylar humerus fractures are common among the pediatric population and can lead to concomitant injury, including compromise of the brachial artery and median nerve and long-term deformity, such as cubitus varus. These fractures can be difficult to reduce, and there is little consensus regarding the optimal technique for closed reduction and percutaneous pinning. Here, we discuss the management of Gartland III posterolateral supracondylar humerus fractures, including an in-depth technical description of the methods of operative fixation. We describe a lateral pin-only fixation technique for Gartland III posterolateral supracondylar humerus fractures that uses the intact periosteum during reduction of the distal fragment to assist in realigning the medial and lateral columns anatomically. We also discuss a safe method for placing a medial-based pin if there is persistent rotational instability at the fracture site after placement of the laterally based pins.

Abstract
CASE A 14-year-old girl sustained a posterior elbow dislocation and presented with a proximal radioulnar translocation (PRUT) and a displaced fracture of the radial head. Reduction of the elbow dislocation and the proximal radioulnar translocation were achieved by external manipulation in the operating room. The radial head was not amenable to closed reduction and remained entrapped in the anteromedial compartment of the elbow. So open reduction and internal stabilization was carried out. CONCLUSIONS In PRUT, closed reduction should be attempted. The radial head should be preserved even if it is fully dislocated from metaphysis. Retrograde intramedullary radial nailing provides enough stability of the fracture to promote early mobilization and facilitate union.

Abstract
Background: Elbow dislocation is the second common dislocation in adults, after the shoulder. The anatomical proximity to the joint of the brachial artery could lead to concomitant vascular injuries, even if their occurrence remains very rare. Method: It is reported the case of a right-hand-dominant 42-year-old man who sustained a simple closed posterior elbow dislocation of his left elbow, associated to a complete brachial artery rupture. He urgently underwent the reduction of the joint dislocation and an artery-repairing surgical procedure using a graft from ipsilateral saphenous vein. Results: The full functional capacity of the elbow was obtained. Conclusions: The abundance of the brachial artery collateral network may hide the presence of a vascular injury, potentially associated to a closed elbow dislocation. Therefore, a high index of suspicious should be maintained. The Emergency Team plays a crucial role in its early diagnosis, which is essential to avoid irreversible ischemia related damages. A prompt reduction of the joint dislocation and the vascular injury surgical repair are required. Regarding the treatment of the concomitant collateral ligaments and capsular injuries, the indication to proceed to the simultaneous ligaments reconstruction is still controversial in literature.

Abstract
Two surgical approaches, an anterolateral and a posterolateral approach, have been advocated for lateral condylar fractures (LCFs) of the humerus in children. The purpose of this study was to evaluate the radiographic and clinical outcomes of the 2 surgical approaches. METHODS We retrospectively analyzed the data of consecutive patients <15 years of age with an LCF treated via open reduction and internal fixation through 1 of 2 surgical approaches during the period of April 2000 to March 2019. Patients were classified into the anterolateral (AL) and posterolateral (PL) groups, according to the surgical approach used. Postoperative complications and radiographic and clinical findings (including range of motion and findings on the basis of the Flynn criteria) were investigated. To investigate humeral deformity, the Baumann angle and the carrying angle were measured on anteroposterior radiographs. RESULTS Sixty-one of 82 patients met the inclusion criteria. The AL group included 17 patients (13 male, 4 female), and the PL group included 44 patients (28 male, 16 female). In the PL group, 7 patients had cubitus varus deformity, 3 had malunion due to unacceptable reduction of fracture fragments, and 6 had elbow joint contracture. In the AL group, the overall clinical results were excellent for 15 patients and good for 2. In the PL group, the clinical results were excellent for 12 patients, good for 14, fair for 6, and poor for 12. CONCLUSIONS An anterolateral approach would be the optimal approach for an LCF in pediatric patients. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Background The pattern of transcondylar fracture of the humerus is unique and the incidence rate is very low. Stable internal fixation may be difficult to achieve, and complications have been reported at a higher rate. The purpose was to report the outcomes of open reduction and internal fixation (ORIF) for transcondylar fractures of the humerus. Methods Seventeen patients were included between January 2014 and December 2017. ORIF was performed using anatomic distal humerus plates. Results were evaluated by range of motion, Mayo Elbow Performance Score (MEPS), and complications. We analyzed the results according to ulnar nerve transposition status and fixation pattern. Results The mean range of elbow motion was 117° flexion and 20° extension. The MEPS was excellent in 12, good in 3, fair in 1, and poor in 1. There were in total 5 cases of complications among 17 patients: 1 with nonunion, 1 with ulnar neuropathy, 2 with delayed union, and 1 with heterotopic ossification. The results according to ulna nerve transposition and fixation pattern showed no difference. Conclusions For reliable and good results, rigid fixation using anatomic plates and appropriate immobilization of the fracture site are key factors in the treatment. In our case series, the overall outcome was good and there were 2 major complications. The ORIF using anatomic plates can be a reliable treatment option for transcondylar humeral fractures.

Abstract
Background Hegemann disease and fishtail deformity are classified as growth disturbances in the physeal plate of the humeral trochlea. It is questionable if these 2 diseases should be considered as 2 distinct conditions. The aims of this study are to (1) point out similarities between both conditions, (2) discuss etiology, and (3) provide diagnostic tools. Methods In a multicenter prospective cohort study, 19 patients with growth disturbance of the humeral trochlea were included. Assessment consisted of a detailed history, physical examination, and standard radiographs in 2 directions. The radiographs were evaluated for skeletal age, carrying angles, and trochlear notch angles. Statistical analysis was performed using Stata. Results A total of 19 patients were included: 2 males (11%) and 17 females (89%). The mean age of the patients was 12.8 years. In 17 patients (89%), a traumatic injury of the elbow was reported, before presentation. Decreased trochlear notch angle (<104°) was seen in 16 patients (84%). Accelerated closure of the growth plate of the affected elbow was seen in all skeletally immature patients. Conclusions The main risk factor for both Hegemann disease and fishtail deformity is an injury of the elbow with open growth plates. Imaging studies support the hypothesis that both diseases are likely to be a continuum of the same process. Therefore, we propose to use 1 nomenclature for this pathologic process: post-traumatic disturbance of the epiphysis of the humeral trochlea.

Abstract
The shape and size of the radial head is highly variable but correlates to the contralateral side. The radial head is a secondary stabilizer to valgus stress and provides lateral stability. The modified Mason-Hotchkiss classification is the most commonly used and describes three types, depending on the number of fragments and their displacement. Type 1 fractures are typically treated conservatively. Surgical reduction and fixation are recommended for type 2 fractures, if there is a mechanical block to motion. This can be done arthroscopically or open. Controversy exists for two-part fractures with >2 mm and <5 mm displacement, without a mechanical bloc as good results have been published with conservative treatment. Type 3 fractures are often treated with radial head replacement. Although radial head resection is also an option as long-term results have been shown to be favourable. Radial head arthroplasty is recommended in type 3 fractures with ligamentous injury or proximal ulna fractures. Failure of primary radial head replacement may be due to several factors. Identification of the cause of failure is essential. Failed radial head arthroplasty can be treated by implant removal alone, interposition arthroplasty, revision radial head replacement either as a single stage or two-stage procedure.

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.

The anterior limited approach of the elbow for the treatment of capitellum and trochlea fractures: Surgical technique and clinical experience in eight cases. Injury 2020; 51 Suppl 1:S103-S111.

Abstract
When a coronal fracture affects the capitellum and the trochlea, the Kocher lateral approach may be inadequate for the correct visualisation, reduction and fixation of the fracture. In such cases an associated medial elbow approach may be required, or a posterior transolecranon approach may be preferred. The anterior limited approach to the elbow (ALAE) could be a valid option when treating these types of fracture, as it does not involve the detachment of any muscle group or ligament, thereby facilitating the recovery process. We can also treat associated injuries such as fractures of the radial head or coronoid process with this approach. We describe the surgical technique and the functional outcome of eight patients with a mean of 66 years of age (range, 53-76) who where treated with open reduction and internal fixation for capitellar and trochlear fractures through the ALAE. Patient outcomes were assessed with physical and radiological evaluation, range-of-motion measurements with a follow-up from 24 to 60 months. Two different quality of life questionnaires were carried out: the EuroQol Five Dimensions Questionnaire (EQ-5D) and the patient-answered questionnnaire of the Liverpool Elbow Score patient (PAQ-LES). Four fractures involved the capitellum, one involved the capitellum with the lateral ridge of the trochlea, and three involved the capitellum and trochlea as separate fragments. The patients presented a favorable clinical evolution at a median of 33 months (range, 24-60), with an average of motion of 10-138°. Four patients presented a fracture of the head of the radius (Mason type 2) and 3 fractures of the coronoid (Bryan-Morrey Type 1) associated. All the patients presented radiological consolidation without signs of osteonecrosis, being the average EQ-5D 0.857 (range, 0.36-1.0) and the PAQ-LES of 35 (range 17 to 36). Patients with isolated capitellar fractures had better results than those with trochlear involvement. The presence of associated fractures does not seem to worsen the results. We believe that the ALAE is a technical option to consider for the open surgical treatment of a capitellar fracture with or without involvement of the trochlea. LEVEL OF EVIDENCEIS: Therapeutic Level III.

[PMID: 31303364 DOI: 10.1016/j.jhsa.2019.05.014] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Revised: 03/27/2019] [Accepted: 05/10/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE Autologous bone grafting is commonly used in reconstructive hand surgery. Various sources of nonvascularized autologous bone grafts have been described in the literature. However, in some situations, a vascularized bone graft may be needed. Popular vascularized bone grafts are taken from the distal radius, iliac crest, and medial femoral condyle. The purpose of this study was to examine the feasibility of harvesting a free vascularized bone flap from the proximal ulna. METHODS Latex was injected via the brachial artery to facilitate visualization of perforators in 10 cadaveric specimens. Dissections were performed of the olecranon; all periosteal perforators were noted, and their lengths and diameters recorded. Corticocancellous bone flaps with their supplying pedicles were harvested. Three additional fresh specimens were injected with india ink via the pedicles to demonstrate perfusion of the harvested bone flap. RESULTS Consistent vascular anatomy supplied the olecranon. A perforator from the posterior ulnar recurrent artery supplied the proximal ulna and olecranon, from which a vascularized bone flap can be harvested. Branches to the flexor carpi ulnaris muscle may allow chimeric flaps to be harvested. Average pedicle length was 5.8 cm and average pedicle diameter was 2.4 mm. India ink injection of the pedicles showed perfusion of the periosteum as well as intraosseous cancellous bone. CONCLUSIONS A vascularized olecranon free flap can be harvested based on the posterior ulnar recurrent artery. Vascular anatomy is consistent and flap harvest is simple and straightforward in all cadaveric specimens. CLINICAL RELEVANCE A vascularized olecranon free flap represents a potential new surgical option when vascular bone flap reconstruction is considered.

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
The purpose of our study was to compare the treatment outcomes and complications between operatively and nonoperatively treated displaced medial epicondyle fractures. Pediatric patients treated for an acute, displaced medial epicondyle fracture between 2005 and 2015 were retrospectively reviewed. A total of 22 operative participants were matched to 22 nonoperative participants, with an average displacement of 9.7 mm in both groups. There was no statistical difference in average length of immobilization, median time to full pronation/supination and flexion/extension, proportion of patients needing physical therapy, and complications. There were no statistical differences in outcomes between operative and nonoperatively treated, moderately displaced, pediatric medial epicondyle fractures. This suggests that operative and nonoperative interventions show equivalent outcomes for these injuries.

Abstract
BACKGROUND Coronal shear fractures of the distal aspect of the humerus that involve the capitellum and the trochlea are rare; nevertheless, they are difficult to treat because of the complex fracture patterns and osteochondral nature of the fragments, limiting optimal screw placement. The use of anterior-to-posterior screw fixation by a lag technique (without countersinking) could potentially improve the strength of the construct. Our primary research question was to anatomically determine if there is a non-articulating zone for screw placement along the anterior aspect of the lateral trochlear ridge (aLTR) throughout normal elbow range of motion. METHODS Eight fresh-frozen cadaveric elbows were used. The region of interest was defined with 3 polymeric pins inserted in the inferior, middle, and superior-most aspects of the aLTR of each elbow, with use of an extensor digitorum communis (EDC) split approach. The elbows were then mounted on a magnetic resonance imaging (MRI)-compatible compression frame and subjected to high-resolution 7-T MRI at 90°, 120°, and 145° of flexion (positions of potential impingement), and at neutral and maximal pronation and maximal supination for each position of flexion. Portions of the aLTR that had free adjacent space were identified using the sagittal and coronal scans. This non-articulating region was identified as the "non-articulating zone" (NAZ). RESULTS The NAZ was found to encompass the proximal 38.2% (range, 30.2% to 48.9%) of the aLTR, measuring, on average, 5.2 mm in width. It was consistently located either directly adjacent to the apex of the ridge or just medial to it. The distal 61.8% of the aLTR articulated with either the ulna or the radial head in some of the elbows. CONCLUSIONS Our results suggest that there is a portion of the aLTR that, despite being covered with articular cartilage, is non-articulating throughout normal elbow range of motion. CLINICAL RELEVANCE In situations in which headless anterior-to-posterior and posterior-to-anterior screw insertion results in inadequate fixation of capitellar-trochlear fractures, anterior-to-posterior lag screw instrumentation along the non-articulating portion of the aLTR may provide a location for additional fixation in some patients. However, because of variation between patients, each case must be individualized.

Abstract
BACKGROUND Osteochondritis dissecans (OCD) of the humeral trochlea is very rare. It may cause pain, mechanical symptoms, and loss of elbow motion, typically in the adolescent athlete. However, little published information is available regarding this condition. PURPOSE To describe the clinical presentation, radiographic features, and prognosis of trochlear OCD. STUDY DESIGN Case series; Level of evidence, 4. METHODS Over a 10-year period, 28 patients presented to a tertiary pediatric hospital with trochlear OCD. Medical records and imaging were analyzed to characterize presentation, lesions appearances, and outcomes. RESULTS Mean ± SD age at presentation was 13.4 ± 1.6 years, and 13 of the 28 patients were male. The most common presenting symptom was pain (93%), followed by crepitus (54%). Evidence of trochlear OCD could be seen on initial radiographs in 94% of cases but was commonly missed. Coexisting capitellar OCD lesions were the most common associated abnormalities seen on magnetic resonance imaging (21%). Investigators noted 2 predominant patterns: "typical" trochlear OCD lesions (89%) were located on the lateral crista of the trochlea, 3.1 ± 4.4 mm lateral to the apex of the trochlear groove. This location corresponded to the medial tip of the capitellar epiphyseal ossification center and was not actually on the trochlear ossification center. "Atypical" trochlear OCD lesions (11%) were located more posteromedially. Trochlear OCD lesions in 4 elbows were managed surgically, while the remainder were managed nonoperatively. At mean ± SD follow-up of 13 ± 8 months, 12 patients (43%) were asymptomatic. A further 5 patients had ongoing crepitus but no pain (18%), and 4 patients (14%) underwent surgical treatment for their trochlear OCD (osteochondral fixation, n = 1; drilling/curettage, n = 3); 3 of the 4 patients experienced some improvement in pain. CONCLUSION Although rare, trochlear OCD can cause considerable elbow problems. Clinicians should be aware of this differential diagnosis. Plain radiographs should be carefully scrutinized for subtle signs of trochlear OCD, particularly in the repetitive or overhead athlete with elbow pain. Although most patients' symptoms will improve with activity modification, some may require surgery.

Abstract
BACKGROUND The vascular supply of the ulnar collateral ligament (UCL) is unknown. Previous studies reported varying success in return-to-play rates after nonoperative management of partial UCL tears and suggested a varying healing capacity as possibly related to the location of the UCL injury. PURPOSE To analyze the macroscopic vascular anatomy of the UCL of the elbow. STUDY DESIGN Descriptive laboratory study. METHODS Eighteen fresh-frozen male cadaveric elbows from 9 donors were sharply dissected 15 cm proximal to the medial epicondyle. Sixty milliliters of India ink was injected through the brachial artery of each elbow. Arms were then frozen at -10°C, radial side down, in 15° to 20° of elbow flexion. A band saw was used to section the frozen elbows into 5-mm coronal or sagittal sections. Sections were cleared for visualization with the modified Spalteholz technique. Images of the specimens were taken, and qualitative description of UCL vascularity was undertaken. RESULTS The authors consistently found a dense blood supply to the proximal UCL, while the distal UCL was hypovascular. They also observed a possible osseous contribution to the proximal UCL from the medial epicondyle in addition to an artery from the flexor/pronator musculature that consistently appeared to provide vascularity to the proximal UCL. The degree of vascular penetration from proximal to distal in the UCL ranged from 39% to 68% of the overall UCL length, with a 49% mean length of vascular penetration of the UCL. CONCLUSION This study found a difference in the vascular supply of the UCL. The proximal UCL was well vascularized, while the distal UCL was hypovascular. This difference in vascular supply may be a factor in the differential healing capacities of the UCL based on the location of injury. CLINICAL RELEVANCE An improved understanding of the macroscopic vascular supply of the UCL may aid in the clinical management of partial UCL tears and suggests an indication for these treatments with respect to location of UCL injuries.

Abstract
Articular fractures of the elbow require direct reduction and interfragmentary fixation to restore anatomic stability. The fragments are often small, with limited bone stock, hence implants are often placed through the articular surface to gain maximal purchase. Traditional techniques involve the use of countersunk cortical screws or cannulated headless compression screws. We describe a technique in which small locking screws are used independently from a plate as a substitute for headless or other traditional screws. This method of fixation negates the need for countersinking the screw head, or over drilling a guide wire, and enables the use of smaller diameter screws which provide excellent purchase in very small fragments. Independent locking screws can be considered for any fracture that previously would have been amenable to cortical or headless compression screw fixation. Locking screws from several manufacturers have been used with equal success. Screws can be used in a unicortical manner if necessary, as the grip comes from engaging the subchondral bone with the locking thread. This technique has been used on 35 consecutive articular elbow fractures with a minimum 6-month follow-up. All fractures have achieved bony union within this period, and there have been no loss of fixations or requirement for further surgeries to remove prominent metalwork.

Abstract
BACKGROUND Open reduction and internal fixation is the adequate treatment for capitellar and trochlear fractures. Given the low incidence of this type of fractures, it is difficult to constitute a universally accepted method for fixation. Thus, we hypothesised that combined use of Kirschner wires (K-wires), absorbable rods and sutures for fixation and post-operative hinged external fixator for early rehabilitation exercise can restore elbow joint function well. METHODS This retrospective study included 20 patients with a mean age of 48.3 (range 16-76) years. According to the Dubberley classification, fractures were classified on plain radiographs, computed tomography images and intra-operative findings. All patients were evaluated by the range of motion of the elbow and the Broberg-Morrey score. RESULTS All fractures had healed without non-union, and the average time was 13.6 (range 8-17) weeks. The mean follow-up was 42.5 (range 24-80) months. The mean flexion was 117.1° (range 90°-135°), and the mean extension was 17.5° (range 0°-45°). The mean pronation was 74.4° (range 45°-85°), and the mean supination was 84.3° (range 60°-90°). The average Broberg-Morrey score was 86.2 (range 68-98) points with 10 excellent, 7 good and 3 fair results. CONCLUSION K-wires, absorbable rods and sutures combined with hinged external fixator are feasible for fixation of capitellar and trochlear fractures. However, due to the absence of a control group (such as Herbert screw fixation), comparative studies are still needed to demonstrate the safety and reliability of K-wires for fixation.

Abstract
BACKGROUND Osteochondritis dissecans (OCD) of the capitellum is a rare but potentially debilitating condition. We sought to determine the healing potential of stable capitellar OCD treated nonoperatively, as well as factors predictive of successful nonoperative management. METHODS We performed a retrospective review of patients younger than 19 years who presented with stable OCD of the capitellum and were treated nonoperatively for a minimum of 2 months. The average clinical and radiographic follow-up period was 12.1 months (range, 3.1-63.7 months). A multivariable logistic regression model was used to determine independent predictors of healing. RESULTS The study included 89 patients (93 elbows), including 49 male patients (55%); the mean age was 12.7 years (range, 8.9-18.6 years). Of the 93 elbows, 50 (53.8%) had successfully healed at a mean of 8.3 months. The symptom duration was significantly shorter in the healing group than the nonhealing group (5.3 ± 4.4 months vs 8.8 ± 9.0 months, P = .02). There were no significant differences in age, physeal status, sex, hand dominance, or sport. Hefti stage I lesions had a higher rate of healing (64.3%) than stage II (31.4%, P = .004), as did OCDs without cyst-like lesions (CLLs, 62.0%) compared with those with CLLs (20.8%, P = .001). The normalized lesion area was significantly larger in the nonhealing group (26.9% vs 18.6%, P < .001). A smaller normalized area and the absence of CLLs were independent predictors of healing. CONCLUSIONS Over half of stable capitellar OCD lesions have the potential to heal with activity restriction. Smaller lesions without CLLs are more likely to heal with nonoperative treatment.

Abstract
To evaluate the clinical outcomes of an anterolateral approach for lateral humeral condylar fractures in children. The patients aged < 15 years undergoing surgery with an anterolateral approach for humeral lateral condylar fractures between April 2005 and March 2014 were investigated. Medical records and radiographs from 15 patients were reviewed. Average patient age at surgery was 6.0 years (range, 3-10 years). Based on Jakob's classification, 12 patients had type II fractures, and 3 patients had type III fractures. Based on Milch classification, 1 elbow was type I, and 14 elbows were type II. The average postoperative follow-up duration was 16.4 months (range, 6-58 months). Postoperative complications, and radiographic and clinical findings, including range of motion and Flynn criteria were evaluated. To evaluate humeral deformity, Baumann angle (BA) and the carrying angle (CA) were calculated on anteroposterior radiographs. There were no postoperative complications, including secondary displacement, deep infection, nonunion, avascular necrosis, or cubitus varus or valgus deformity. In the injured elbow, follow-up radiographs revealed an average BA of 69.1° (range, 57-84°), versus 70.9° (range, 61-83°) on the contralateral side. The average CA on the injured side was 10.3° (range, 4-20°) versus 12.3° (range, 6-24°) on the contralateral side. BA gain and CA loss (affected- compared with contralateral sides) averaged -1.4° (range, -17° to 9°) and 2.3° (range, -2° to 6°), respectively. The mean range of motion in the affected elbow averaged 4.7° (range, 0-15°) in extension and 139.7° (range, 135-140°) in flexion. Over 5° loss of range of motion in the affected elbow compared with the contralateral side was not observed. However, 2 patients experienced over 5° loss of CA in the affected elbow versus the contralateral side. Based on Flynn criteria, clinical results for both cosmetics and function were excellent in 13 patients, and good in 2. The advantages of the anterolateral approach are combining an optimal view of the anterior articular surface of the trochlea and capitellum and a limited risk of devascularization injury. We strongly recommend an anterolateral approach for these fractures in children to prevent postoperative deformity and to achieve anatomical reduction and reliable fixation.

Abstract
Background Although vascularity plays a critical role in healing after ulnar collateral ligament (UCL) reconstruction, intraosseous blood flow to the medial epicondyle (ME) and sublime tubercle remains undefined. Purpose To quantify vascular disruption caused by tunnel drilling with the modified Jobe and docking techniques for UCL reconstruction. Study Design Controlled laboratory study. Methods Eight matched pairs (16 specimens) of fresh-frozen cadaveric upper extremities were randomized to 1 of 2 study groups: docking technique or modified Jobe technique. One elbow in each pair underwent tunnel drilling by the assigned technique, while the contralateral elbow served as a control. Pregadolinium and postgadolinium magnetic resonance imaging were performed to quantify intraosseous vascularity within the ME, trochlea, and proximal ulna. Three-dimensional computed tomography (CT) and gross dissection were performed to assess terminal vessel integrity. Results Ulnar tunnel drilling had minimal impact on vascularity of the proximal ulna, with maintenance of >95% blood flow for each technique. Perfusion in the ME was reduced 14% (to 86% of baseline) for the docking technique and 60% (to 40% of baseline) for the modified Jobe technique (mean difference, 46%; P = .029). Three-dimensional CT and gross dissection revealed increased disruption of small perforating vessels of the posterior aspect of the ME for the modified Jobe technique. Conclusion Although tunnel drilling in the sublime tubercle appears to have a minimal effect on intraosseous vascularity of the proximal ulna, both the docking and modified Jobe techniques reduce flow in the ME. This reduction was 4 times greater for the modified Jobe technique, and these findings have important implications for UCL reconstruction surgery. Clinical Relevance As the rate of revision UCL reconstructions continues to rise, investigation into causes for failure of primary surgery is needed. One potential cause is poor tendon-to-bone healing due to inadequate vascularity. This study quantifies the amount of vascular insult that is incurred in the ME during UCL reconstruction. While vascular insult is only one of many factors that affects the surgical success rate, surgeons performing this procedure should be mindful of this potential for vascular disruption.
