Abstract
Distal humerus fractures are a contemporary problem because the life expectancy, autonomy and functional demands of older patients continue to grow. This is combined with surgical advances in bone reconstruction, especially in fragile patients. A distal humerus fracture in an older adult is a serious injury with an uncertain prognosis. In fact, damage to the elbow joint in this complex anatomical area overwhelmed by low-quality bone occurs in patients who often have unfavorable characteristics (fragile skin, low physiological reserves, organ failure) combined with pharmaceutical treatments that can be iatrogenic. The treatment indication must not be based solely on the conventional radiographs used for classification purposes; the fracture and bone quality must be analyzed in three dimensions. Also, the surgeon must understand the patient's needs, worries and risks fully to decide between conservative treatment and anatomical locking plate fixation or elbow arthroplasty (hemi or total). In the end, the chosen treatment must allow at least 100̊ and preferably 120̊ of flexion-extension at the elbow. In this age range, the choice between arthroplasty and plate fixation is definitive; the surgical approach must make it possible to carry out either option, with arthroplasty implants available in case the trochlear fracture cannot be plated. The aim of this lecture is to provide a fresh perspective on the anatomy of the distal humerus, its fracture and the best surgical approaches, discuss how to decide on the indication, outline the safest and most reliable ways to reconstruct and stabilize the elbow, and lastly, summarize the expected outcomes and potential complications of each treatment option. Level of evidence: V; expert opinion.

Abstract
INTRODUCTION There is no "gold standard" for the type of plate to be used for distal extra-articular humeral fractures; the most used is plating of each column. The objective was to evaluate the short-term clinical and radiological results of a Y- anatomical and innovative locking plate (YALP). HYPOTHESIS The hypothesis is: this anatomical and innovative locking plate will produce satisfactory and reliable results on extra-articular distal humerus fracture superior to double plate fixation. MATERIALS AND METHODS In a retrospective observational multicenter study, all patients with a distal humerus fracture type 13 A2.2 according to AO classification fixed with a new Y-plate (YALP) were compared to the results of double plate fixation for the same type of fracture. With a follow-up of more than 12 months, the objective and subjective clinical elbow criteria as well as the overall function of the upper limb and radiological assessment were collected. RESULTS With an average follow up of 24±11 months, 26 patients met the inclusion criteria and received a YALP and 24 patients received double plate. All patients whose fracture had healed except one were pain-free (mean VAS 0.3±0.6). All patients had good subjective results (mean SEV 96%±4). Elbow function was excellent (mean total MEPS 96±4) with normal triceps strength (23/24 patients had a triceps strength graded 5/5 and one patient 4/5) and range of motion (flexion 139±8, extension -7±8 and pronosupination greater than 155 degrees). The operating time was shorter in the YALP group (84 ± 23minutes versus 97 ± 28minutes, p=0.03). The double plate group had more complications; the overall complication rate was significantly higher (p=0.02) in the double 90-degree plate group (12/24, 50%) with four nonunions, four symptomatic ulnar nerves, three hardware removals for pain and one radial nerve injury versus 5/26 complications (19%, p=0.02) in the Y-plate group: one iliac graft for nonunion, 1 plate removal due to functional discomfort, 1 twisted YALP, 1 broke interfragmentary screw and one symptomatic ulnar nerve. DASH, SEV, MEPS scores and flexion-extension range were better in the YALP group. DISCUSSION YALP produces satisfactory results in supracondylar fractures of the distal humerus. The results of YALP appear to be better than the results with two 90° plates for the same fracture type with a shorter operative time and easier management of fractures with proximal diaphyseal extension.

Abstract
Background Open reduction and internal fixation (ORIF) is the standard treatment for multifragmentary intra-articular distal humeral fractures. Fractures not amenable by ORIF are treated with total elbow arthroplasty (TEA). In recent years, elbow hemiarthroplasty (EHA) has been used as an alternative to TEA, as weight bearing restrictions and risk of component loosening are lower. We systematically reviewed the literature reporting functional outcomes and complication rates after either EHA or ORIF for Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) type 13C fractures. Methods We searched PubMed, Embase, The Cochrane Library, and Scopus. The inclusion criteria were at least 5 patients, aged ≥50 years, AO/OTA type 13C fracture treated with ORIF or EHA, and evaluation with the Mayo Elbow Performance Score. Literature screening and data extraction were conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. The results were synthesized qualitatively using weighted means. No comparative statistical analyses were done. Results We included 27 articles, which included 96 patients treated with EHA and 535 patients treated with ORIF. We identified 1 randomized controlled trial and 26 case series. The weighted mean Mayo Elbow Performance Score was 86.9 (n = 89) in the EHA group and 84.7 (n = 535) in the ORIF group. There were 26 (33%) complications (n = 78) in the EHA group and 103 (38%) complications (n = 270) in the ORIF group. Complication rates were generally high in both groups. Conclusion We found comparable results of EHA and ORIF, which indicate that EHA is a viable treatment option for AO/OTA type 13C fractures not amenable by ORIF. Because of high risk of bias, interpretation of the results should be done with caution.

Abstract
Background Open reduction and plate fixation are the preferred treatment options for most distal humerus fractures in adults. However, it is often challenging for orthopedic surgeons because of the complex anatomy and the difficulty in achieving stable fixation. This multicenter study aimed to analyze the complication types and rates of patients with distal humerus fractures treated with open reduction and plate fixation, and compare the results with those found in the literature. In addition, we describe the clinical outcomes.
Methods This retrospective multicenter study was conducted between September 2001 and March 2021 and included data from four hospitals. In total, 349 elbows underwent surgical treatment at these hospitals during the study period. Patients > 17 years of age who were treated by plate fixation were included, and patients who were treated by other fixation methods were excluded. A total of 170 patients were included in the study. The following types of complications were investigated: (1) nerve related; (2) fixation and instrument related; (3) osteosynthesis related; (4) infection; and (5) others.
Results The following complications were found: (1) 26 (15.3%) cases of postoperative ulnar nerve symptoms; 4 (2.4%) of postoperative radial nerve symptoms; (2) one (0.6%) case of screw joint penetration and screw loosening; and eight (4.7%) cases of hardware removal due to instrument skin irritation; (3) seven (4.1%) cases of nonunion; (4) two (1.2%) and four (2.2%) cases of superficial and deep infection, respectively, and seven (3.9%) cases of wound complication; and (5) 37 (21.8%) cases of heterotrophic ossification, 79 (46.5%) cases of elbow stiffness (did not achieve functional range of motion [ROM]), and 41 (24.1%) cases of osteoarthritis over Broberg and Morrey Grade I. Paradoxically, the postoperative ulnar nerve symptoms were more frequent in the prophylactic ulnar nerve anterior transposition group. However, this difference was not statistically significant (p = 0.086). The mean ROM was 123.5° flexion to 9.5° extension. The average Disabilities of the Arm, Shoulder and Hand (DASH) score was 14.5 ± 15.6. Conclusions Open reduction and plate fixation for distal humeral fractures is a reasonable treatment option with acceptable complication rates and favorable clinical outcomes. Surgeons must be vigilant about ulnar nerve complications. Level of Evidence Therapeutic Level III.

Abstract
Introduction Treatment of intra-articular fractures of the distal humerus is challenging due to their complexity, comminution, and associated complications. The evolution of surgical approaches and the design of elbow-specific implants over the last decades have failed to improve clinical and radiological outcomes. Studies are sparse regarding the long-term influence of surgical treatment of these types of fractures in the upper limb function. The purpose of the current study was to retrospectively review the long-term functional outcome and complications of all intraarticular (AO type B, C) distal humerus fractures treated surgically in a university hospital during the last 25 years. Material and methods The study included patients who were surgically treated for an intra-articular distal humerus fracture between March 1991 and May 2016. Our initial search, using ICD-10 codes, identified 63 patients in the specific time period. Twelve patients had died, nine declined to participate, eight had emigrated, nine could not be located and one patient was excluded as he suffered from quadriplegia unrelated to the initial injury. The remaining 25 patients (mean age at surgery 44.2±19.67) were included in a follow-up study protocol. Functional outcome was evaluated according to Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH). Pain was assessed using the Numerical Pain Rating Scale (NPRS) and subjects were asked to rate their satisfaction. Perioperative and late complications were recorded as well. Results The average follow-up was 158.16 ± 73.73 months. The average score was 89.4 ± 12.36 for MEPS, 42.68 ± 4.03 for OES, and 8.1 ± 15.38 for the QuickDASH. The patient satisfaction was rated 3.8 ± 1.08 on average. The mean flexion of the affected elbow was 137.6 ± 12.68 degrees while extension deficit was present in 14/25 patients, with a mean of 8.6 ± 8.96 degrees. We did not observe any mal- or non-unions. The re-operation rate was 32% primarily due to stiffness and irritation from the hardware. We noticed one spontaneously resolved ulnar nerve palsy, one combined radial, and ulnar nerve palsy after extensive arthrolysis that also resolved two cases of heterotopic ossification, one case of implant failure, and two cases of infection - one superficial, which was managed with antibiotics, and the other was deep managed with surgical drainage. Conclusions In our series, we found a satisfying range of motion, good functional outcome, and adequate ability to perform daily activities at a very long follow-up. Posttraumatic arthritis, whenever present, does not seriously affect functional performance. Level of evidence: IV

Abstract
Background The aim of this study was to discuss the treatment of extra-articular distal humeral shaft fractures using ultrasound-guided preoperative localization of radial nerve. Methods Between May 2010 and December 2019, 56 patients with extra-articular distal humeral shaft fractures were retrospectively reviewed. Twenty eight patients were received examination by using preoperative localization of radial nerve guided by ultrasound-guided preoperative localization (group A) and 28 control patients without ultrasound-guided (group B). All patients were treated surgically for distal humeral shaft fractures by posterior approach techniques. Operative time, radial nerve exposure time, intraoperative bleeding volume, union time and iatrogenic radial nerve palsy rate were compared between the two groups. Elbow function was also evaluated using the Mayo Elbow Performance Score (MEPS). Results A significant difference was observed between the two groups, Operative time (113.25 min vs 135.86 min) (P < 0.001), radial nerve exposure time (20.82 min vs 32.53 min) (P < 0.001), intraoperative bleeding volume (246.80 ml vs 335.52 ml) (P < 0.001). However, iatrogenic radial nerve palsy rate (3.6% vs 7.1%) (P = 0.129), the fracture union time (13.52 months vs 12.96 months) (P = 0.796) and the MEPS score (87.56 vs 86.38) (P = 0.594) were no significantly different in both groups. Conclusions The study demonstrates that ultrasound-guided preoperative localization is an effective approach in the treatment of extra-articular distal humeral shaft fracture by revealing radial nerve, which may help reduce the operative time, radial nerve exposure time and the intraoperative bleeding volume.

Abstract
BACKGROUND Due to the complexity of distal humerusfractures and often poor bone quality in elderly patients, these entities remain a challenge. However, because of a high rate of complications related to total elbow prostheses, reconstruction of distal humerus fractures should still be considered a therapeutic option, also in the elderly patient. The purpose of the present study was to investigate the clinical outcomes after open reduction and internal fixation and to evaluate whether the results justify reconstruction even in elderly patients. We hypothesized that despite advanced age, reasonable clinical results can be achieved, using a standardized surgical technique and aftertreatment protocol for the treatment of distal humerus fractures in elderly patients. METHODS Between 2004 and 2012, 30 patients with a mean age of 78 years at the time of injury with a recent distal humerus fracture were evaluated. All patients underwent the identical aftertreatment protocol with no weight bearing for 6 weeks and weekly increasing range of motion. Follow-up rate was 90%. 22 patients were treated with double plate, 4 with single plate, and 1 with screw fixation only. Patients were evaluated based on clinical criteria. Primary outcome measures were Mayo Elbow Performance Score, VAS and joint range of motion, secondary was radiological evaluation. RESULTS After a mean follow-up period of 3.8 years (min. 1 year, max. 9 years, SD ± 2), the average range of motion was flexion of 127° (min. 100°; max. 150°; SD ± 16.5) and average loss of extension of 20.9° (min. 5°; max. 40°; SD ± 11). Average pronation and supination was 68.3° (min. 0°; max. 90°; SD ± 25.3) and 75.3° (min. 0°; max. 90°; SD ± 19.7), respectively. Average Mayo Elbow Performance (MEPS) score was 88.7 (min. 60; max. 100; SD ± 12.1). 6 patients developed heterotopic ossification without significant effect on the clinical outcome. 7 patients had radiological evidence of at least partial non-union with one requiring revision, 2 discrete hardware dislocations were treated conservatively. There were no infections in the presented cohort. Our results regarding the surgical approach showed significantly higher patient satisfaction scores in the osteotomy group, compared to the group with Triceps-On Approach (PTOA). CONCLUSION The present data support indication for open reduction internal fixation (ORIF) even in the elderly patient. Advanced age should not be seen as a contraindication for ORIF of fractures of the distal humerus. Although the rate of complications is higher than in younger patients, complications such as non-union are often asymptomatic, patient satisfaction scores are high, and the possible devastating complications of failed elbow replacement can be evaded.

Abstract
BACKGROUND The purpose of this study was to report the functional outcomes and complications after open reduction and internal fixation (ORIF) for Arbeitsgemeinschaft für Osteosynthesefragen (AO)/Orthopaedic Trauma Association (OTA) type 13-C2 and -C3 acute distal humeral fractures with minimum 2-year follow-up. Our hypothesis was that ORIF would provide functional outcomes that are comparable to those of total elbow arthroplasty and elbow hemiarthroplasty reported in the literature. MATERIALS AND METHODS During a 6-year period, 23 patients aged > 45 years were treated with double plating for AO/OTA type 13-C2 or -C3 fractures. The mean age was 62 years (range, 46-80 years). The Oxford Elbow Score was used as the primary outcome; the Mayo Elbow Performance Score, pain severity score (on a visual analog scale), range of motion, reoperations, and complications were used as secondary outcomes. RESULTS The median Oxford Elbow Score was 42 (range, 25-48), where a score of 48 represents a normal elbow; 20 patients achieved good to excellent outcomes, and 3 achieved fair outcomes. The median Mayo Elbow Performance Score was 85 (range, 60-100), where a score of 100 represents a normal elbow; 18 patients achieved good to excellent outcomes, and 5 achieved fair outcomes. The median visual analog scale score was 2 (range, 0-5). The median flexion-extension and supination-pronation arcs were 120° (range, 70°-155°) and 160° (range, 75°-170°), respectively. Eight complications were recorded in 7 patients; 4 of them required reoperation because of fracture pseudarthrosis or elbow stiffness. Ten patients were working at the time of trauma, and nine of them returned to the same occupation. Our results are comparable to the results of previously published studies regarding the outcome of ORIF, elbow hemiarthroplasty, or total elbow arthroplasty for AO/OTA type 13-C fractures. CONCLUSION ORIF is a reliable treatment option for AO/OTA type 13-C2 and -C3 acute distal humeral fractures in middle-aged and elderly patients, despite the considerable rate of complications. Good to excellent results can be obtained in most patients.

Abstract
Approximately 4.1% of all fractures in the elderly involve the elbow. Most elbow injuries in geriatric patients occur as the result of low-energy mechanisms such as falls from standing height. Elbow injuries in elderly patients present complex challenges because of insufficient bone quality, comminution, articular fragmentation, and preexisting conditions, such as arthritis. Medical comorbidities and baseline level of function must be heavily considered in surgical decision making.

Abstract
BACKGROUND The purpose of this study is to evaluate the clinical outcomes of the elderly with coronal shear fractures (CSFs) of the distal humerus who had undergone open reduction and internal fixation (ORIF). METHODS Between April 2002 and March 2019, eight elderly patients (76.3 ± 5.1 years)with CSFs of the distal humerus were investigated retrospectively. Postoperative complications, the range of motion (ROM) of the elbow joint, and functional elbow scoring (Mayo elbow performance score; MEPS) were assessed. RESULTS The mean follow-up duration was 23.6 ± 13.9 months. CSFs were treated by a buried implantable headless screw or Kirshner wires or bioresorbable screw with/without lateral locking plates. There were no superficial or deep infections, or elbow joint instability. Seven patients obtained fracture healing, but one patient showed non-union. Osteochondritis dissecans was present in one patient. Three patients showed step-off deformity (> 2 mm) of the articular surface. Two patients displayed a collapse of the fractured articular surface. A patient with severe comminution of both the capitellum and the trochlear showed the collapse of the whole articular surface with osteonecrosis of the capitellum and trochlea. Mean the range of motion of the elbow were flexion, 116.3±12.7° and extension, -28.8±14.1°. The mean MEPS was 78.8±10.2 points, representing patients who scored an excellent (n=1), good (n=3), and fair (n=4). CONCLUSION ORIF yielded satisfactory outcomes for theelderly with noncomminuted CSF of the distal humerus. However, the cases with comminuted articular fragment or complex posterior fractures were still challenging.

Some outcomes of patients treated operatively for distal humerus fractures are affected by hand dominance. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 31:1507-1513. [PMID: 33660048 DOI: 10.1007/s00590-021-02915-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Accepted: 02/12/2021] [Indexed: 10/22/2022]
Abstract
PURPOSE This study sought to compare postoperative outcomes and complications between patients with distal humerus fractures treated with open reduction and internal fixation (ORIF) of their non-dominant versus dominant arm. METHODS A retrospective review of all patients who sustained a distal humerus fracture treated operatively with ORIF at one academic institution between 2011 and 2015 was performed. Measured outcomes included complications, time to fracture union, painful hardware, removal of hardware, Mayo Elbow Performance Index (MEPI), and elbow range of motion. Differences in outcomes between patients who underwent surgery of their dominant upper extremity and those who underwent surgery of their non-dominant extremity were assessed. RESULTS Sixty-nine patients met inclusion criteria. Forty (58.0%) underwent ORIF of a distal humerus fracture on their non-dominant arm and 29 (42.0%) on their dominant arm. Groups did not differ with respect to demographics, injury information, or surgical management. Mean overall follow-up was 14.1 ± 10.5 months, with all patients achieving at least 6 months follow-up. The non-dominant cohort experienced a higher proportion of postoperative complications (P = 0.048), painful hardware (P = 0.018), and removal of hardware (P = 0.002). At latest follow-up, the non-dominant cohort had lower MEPI scores (P = 0.037) but no difference in elbow arc of motion (P = 0.314). CONCLUSION Patients who sustained a distal humerus fracture of their non-dominant arm treated with ORIF experienced more postoperative complications, reported a greater incidence of painful hardware, underwent removal of hardware more often, and had worse functional recovery in this study. Physicians should emphasize the importance of physical therapy and maintaining arm movement especially when the non-dominant arm is involved following distal humerus fracture repair.

Correlation between modified trochleocapitellar index and post-traumatic elbow stiffness in type C2-3 distal humeral fractures among adults. J Shoulder Elbow Surg 2020; 29:1876-1883. [PMID: 32446760 DOI: 10.1016/j.jse.2020.02.016] [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: 09/28/2019] [Revised: 02/16/2020] [Accepted: 02/20/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND The purpose of this study was to propose the modified trochleocapitellar index (mTCI), assess its reliability, and evaluate its correlation with post-traumatic elbow stiffness in type C2-3 distal humeral fractures among adults. METHODS From January 2013 to June 2017, a total of 141 patients with type C2-3 distal humeral fractures were included. The mTCI was calculated as the ratio between the modified trochlear and capitellar angles relative to the humeral axis (mTCI-HA), lateral humeral line (mTCI-LHL), and medial humeral line (mTCI-MHL) from anteroposterior radiographs taken immediately after the operation. The patients were divided into group A (with elbow stiffness) and group B (without elbow stiffness) based on follow-up results. To determine risk factors for elbow stiffness, univariate and logistic regression analyses were performed on each radiographic parameter separately, together with other clinical variables. Interrater reliability was assessed for all measurements. RESULTS Specific optimal ranges of value were identified for mTCI-HA (0.750-0.875), mTCI-LHL (0.640-1.060), and mTCI-MHL (0.740-0.900), beyond which the likelihood of elbow stiffness significantly increased (P < .001). By multivariate analysis, mTCI-HA (odds ratio [OR] 26.22, 95% confidence interval [CI] 3.39-203.07, P = .002), mTCI-LHL (OR 5.37, 95% CI 2.17-13.28, P < .001), and mTCI-MHL (OR 5.95, 95% CI 1.91-18.56, P = .002) values beyond the optimal ranges were identified as the independent risk factors for elbow stiffness. The interrater reliability of mTCI-HA, mTCI-LHL, and mTCI-MHL was 0.986, 0.983, and 0.987, respectively. CONCLUSION The mTCI measurement method is reliable. Either too small or too large mTCI values were associated with post-traumatic elbow stiffness among adult patients with type C2-3 distal humeral fractures. The mTCI-HA showed a better predictive value than mTCI-LHL and mTCI-MHL.

Abstract
INTRODUCTION Working hypothesis: The distal humeral bone density influences supracondylar fracture threshold. The aim of this study was first to develop a reproducible model of intra-articular distal humeral fractures and second to establish a relationship between bone mineral density (BMD) and the fracture threshold of the humerus. MATERIALS AND METHODS An original model of the fracture was developed using ten sawbones. After obtaining a reproducible and clinically relevant fracture model, we tested 21 cadaveric distal humeri for which the BMD was known with a stainless-steel custom-made proximal ulna jig. Fractures were created using a servo hydraulic-testing machine in axial compression to simulate a fall onto an outstretched hand. Fracture lines, load to failure, and rigidity of the bone were recorded based on the stress-strain curves. RESULTS The fracture generation was reliable, reproducible, and clinically relevant (type B2). A significant correlation between the BMD and the fracture threshold was found. Mean threshold was 901.86 N/m2. Mean distal humerus BMD was 0.9097 g/cm2 (r = 0.7321). CONCLUSIONS We developed a reproducible articular fracture of the distal humerus model and found a correlation between the fracture threshold and bone mineral density.

Abstract
BACKGROUND The purpose of this study was to identify complications after operative treatment of distal humerus fractures with anatomic, pre-contoured, locking distal humeral plates. We hypothesized that these fractures have high complication rates despite the use of these modern implants. MATERIALS AND METHODS Between 2010 and 2018, 43 adult patients with a distal humerus fracture underwent open reduction and internal fixation (ORIF) at a Level I trauma center. Pre-operative variables, including medical comorbidities, mechanism of injury, open or closed fracture, AO/OTA fracture classification (Type A, B, or C), and nerve palsy, were recorded. Intra-operative variables including surgical approach, ulnar nerve transposition, and plate configuration were recorded. Anatomic, pre-contoured, locking distal humeral plates were used in all patients. Various plating systems were used based on surgeon preference and fracture pattern. Post-operative complications including infection, nonunion, malunion, painful implants, nerve palsy, heterotopic ossification, stiffness, and post-traumatic arthritis were recorded. RESULTS Most fractures were Type C (53%). The posterior olecranon osteotomy approach (51%) and parallel plate configuration (42%) were used in most cases. At a mean follow-up of 15 months, the complication rate was 61% (26/43 patients). Among all patients, 49% (21/43 patients) required a reoperation. Elbow stiffness (19%) was the most common complication followed by nerve palsy (16%). There were four fracture nonunions (9%), deep infections (9%), painful implants (9%), post-traumatic arthritis (9%), and heterotopic ossification (9%). CONCLUSIONS Distal humerus fractures treated with ORIF utilizing anatomic, pre-contoured, locking distal humeral plates have a high complication rate, with many requiring reoperation.

Abstract
To elucidate the clinical outcomes of nonsurgical treatment for transcondylar fractures of the humerus.From April 2010 to March 2018, 32 elbows with AO classification 13A-2.3 transcondylar fractures of the humerus (extra-articular fracture, metaphyseal simple, transverse, transmetaphyseal) in adult patients were treated in our hospital and related facilities. Fifteen of 32 elbows were treated nonsurgically by immobilization with a long-arm cast or splint. Of these, 14 elbows that were followed up for >3 months were investigated. The patients comprised 6 men and 8 women with a mean age at the time of injury of 78 years. We investigated the follow-up period, duration until bone union, complications at final follow-up, radiological evaluation, elbow range of motion (ROM), total elbow joint range (Arc), and clinical outcome (Mayo Elbow Performance Score [MEPS]).The mean follow-up period was 8 months. The mean duration until bone union was 7 weeks. No significant complications were observed at the final examination. The ROM of the injured elbow joint was obtained in 13 patients. At the final follow-up, the mean extension and flexion of the injured elbow was -19.2° and 121.2°, respectively. The mean Arc of the injured elbow joint was 102.3°. Joint contracture (<120° flexion) was observed in 6 of the 13 elbows for which ROM was obtained. No patients complained of residual pain of the elbow joint. The mean MEPS was 93.1 points.There is no objection to the fact that displaced transcondylar fractures of the humerus should be treated surgically. However, significant numbers of intraoperative and postoperative complications of plate osteosynthesis have been reported. Until recently, although few clinical reports regarding nonsurgical treatment for these fractures have been published, several studies have indicated that nonsurgical treatment might be an alternative option for these fractures caused by low-energy trauma. In this study, we presented the radiographic and clinical outcomes of nonsurgical treatment for transcondylar fractures of the humerus. Our study suggests that nonsurgical treatment can be a good option for transcondylar fractures of the humerus.

Abstract
BACKGROUND Primary prosthetic replacement has become an accepted method for the treatment of complex distal humeral fractures. The present study investigated implant survival and adverse events related to this procedure based on available Swedish registries and examined the completeness of the Swedish Elbow Arthroplasty register. MATERIALS AND METHODS Patients treated in Sweden with a primary elbow replacement due to a distal humeral fracture between 1999 and 2014 were identified through 3 different registries: The Swedish Elbow Arthroplasty Register, National Board of Health and Welfare inpatient register, and local registries of all orthopedic departments. Prosthetic survival was examined using Cox regression analysis with Kaplan-Meier plots. Adverse events, defined as medical treatment of the affected elbow besides revision, were analyzed separately. The study included 406 elbows in 405 patients, and no register was complete. RESULTS Implant survival at 10 years was 90% (95% confidence interval, 85%-96%), but only 45 patients had an observation time of 10 years or more because 46% of the patients had died, resulting in a mean observation time of 67 (standard deviation, 47) months. An increase in the use of hemiarthroplasties and a proportional decrease of total elbow arthroplasties was detected. There were 18 revisions (4%), and 26 patients (6%) experienced an adverse event, of whom 16 (4%) required surgery. The completeness of the Swedish Elbow Arthroplasty Register regarding primary arthroplasty was 81%. CONCLUSION Primary arthroplasty as treatment of distal humeral fractures produces reliable results with regards to revisions and other adverse events.

Abstract
OBJECTIVES Distal humerus fractures are challenging to treat, with significant morbidity. Precontoured distal humerus locking plates and total elbow arthroplasty implants have become available in the past 15 years, potentially offering the promise of improved outcomes. However, national data regarding the usage of and in-hospital complications associated with these implants is scarce. Therefore, we aimed to determine if the incidence of inpatients with distal humerus fractures treated with arthroplasty or open reduction and internal fixation (ORIF) changed over time. Secondarily, we sought to determine what demographic factors were associated with arthroplasty versus fixation and compare inpatient outcomes. METHODS Inpatients over 50 years old with operatively treated closed distal humerus fractures were identified between 2002 and 2014 in the Nationwide Inpatient Sample, a nationally representative, all-payer database. Patient demographic factors were associated with treatment type. Outcomes examined included complications, mortality, length-of-stay, and charges; multivariable logistic regression compared associations with treatment. RESULTS Of 56,379 inpatients undergoing surgery, the proportion undergoing arthroplasty rose 2.3-fold from 4.8% to 10.9% from 2002 to 2014 (OR 1.039/year [95% CI [1.016-1.062]). Annual patient volume remained similar. Arthroplasty patients were older than those undergoing fixation (75.5 vs. 71.0 years, p < 0.001), more likely to be female (83.1% vs. 75.4%, p < 0.001), and less likely to be treated at a rural hospital (OR 0.601, 95% CI 0.445-0.812, p < 0.001). There was no significant difference in comorbidities. Arthroplasty patients had similar inpatient medical complication (7.1% vs. 7.8%, OR 0.998, p = 0.988) and mortality rates (0.38% vs. 0.94%, OR 0.426, p = 0.102), a decreased length of stay (by 0.3 days, p = 0.032), but increased hospital charges (by $12,033, p < 0.001). CONCLUSIONS For inpatients over 50 years old with operatively-treated distal humerus fractures, use of elbow arthroplasty has expanded, albeit with increased cost. Further studies may help to delineate the long-term costs and benefits, as well as which patients may benefit from each type of implant. LEVEL OF EVIDENCE Level III, Therapeutic Study.

Abstract
Around one third of humeral fractures and 2–6% of all fractures occur to the distal part of the humerus. There is a bimodal distribution differentiating between young male patients with high-energy and elderly female patients with low-energy trauma related to osteoporosis. The AO classification and Dubberley subclassification are used in daily routine. Most fractures are diagnosed on radiographs. For further evaluation, three-dimensional computed tomography is recommended, especially for comminuted or complex fractures. Owing to the long immobilization and resultant poor functional outcome, conservative treatment is followed for inoperable patients. The operative approach and osteosynthesis depend on the fracture pattern. In A1 avulsion fractures, open reduction and screw fixation are recommended. In A2/A3 fractures, a triceps-sparing approach following a 90° double-plate construction (radial dorsal/ulnar lateral) with locking plates is favored. Partial articular B1/B2 fractures are exposed via a medial or lateral approach using unilateral locking plates to stabilize the medial/lateral column. Coronal shear fractures (B3) are classified after Dubberley and are treated via an extended Kocher approach and headless compression screws in anteroposterior direction. If there is a further posterior comminution or a lateral column fragment, stabilization is needed for the lateral/medial column with a precontoured locking plate. In solely articular fracture patterns, a dorsal approach with either a 90° or 180° double-plate construction is advised. If a reconstruction is not possible owing to fracture complexity or bone quality, total elbow arthroplasty is a viable option. However, lifelong limitation in weight-bearing up to 5 kg, limited longevity, and the potential for complicated revision surgery should be considered.

Abstract
PURPOSE In distal humerus fractures, the goal is to achieve a functional range of motion of 30°-130° which is not always possible. The aims of the study were to evaluate the functional results after distal humerus fracture operation and to investigate the risk factors for stiffness. METHODS Between 2005 and 2014, 75 patients with the mean age of 37.8 years (17-80) underwent open reduction and plate fixation for distal humerus fractures. Range of motion (ROM), Mayo elbow performance scores, and quick DASH scores were used for functional evaluation. Patients were divided into two groups according their ROM. Group 1 had > 100° of extension-flexion ROM and group 2 had < 100°. Older age (> 60), AO type C2-3 fracture, open fracture, longer injury-surgery interval, type of plating, and presence of olecranon osteotomy were investigated as risk factors for poor outcome. RESULTS At a mean follow-up of 25 months (6-80), 40 patients were in group 1 and 35 patients were in group 2. Group 1 had significantly better functional scores than group 2. AO type C2 and C3 fracture (odds ratio (OR) 16.6, p < 0.0001) and injury-surgery interval longer than 7 days (OR 2.59, p 0.047) were found as significant risk factors for stiffness. CONCLUSIONS Patients who had distal humerus fracture should be informed about the risk of elbow stiffness especially in AO type C2-C3 fractures and surgical treatment should be planned without any delay.

Abstract
INTRODUCTION The main purpose of this retrospective, non-randomized, case series study was to evaluate the clinical and radiographic outcomes of distal humerus fractures (DHFs) in a consecutive series of elderly patients operatively treated by two surgeons, and second, to identify proper indications for two elderly age ranges and two fracture pattern groups. MATERIALS AND METHODS From January 2009 to June 2014, 51 patients (pts) underwent open reduction and internal fixation (ORIF) using the locking compression plate (LCP) distal humerus plate (DHP) system at our institution. Medical records and radiographs were retrospectively assessed. Patients were divided into 3 groups according to gender, age (pts <85 years, pts ≥85 years) and AO classification (13-B1-B2-C1-C2 or 13-C3). All subjects completed MEPS, Quick-DASH and SF-36 PCS/MCS scores at final follow-up, and statistical analysis was performed. RESULTS 36 patients (20 women, 16 men), mean age 80.3 years, with AO type 13-B and 13-C DHFs were included with a mean follow-up of 56 months (range 24-92). The most common mechanism of trauma was a fall from ground level (55.6%). The mean MEPS was 78.9 points, Quick-DASH 28.4, SF-36 PCS 48.3 and MCS 48.9. There was statistically significant evidence that having a 13-C3 fracture leads to worse results in MEPS, Quick-DASH and SF-36. The female gender correlates with worse results in SF-36. The patients ≥85 years had a worse prognosis according to Quick-DASH and SF-36, while the AO 13-C3 pattern obtained the worst ROM outcomes versus AO 13 B1-B2-C1-C2 (normal ROM 0°-140°): mean ROM 24°-114° vs 10°-130°, mean flexion deficit 26° vs 10°, mean extension deficit 24° vs 10°, respectively). Complications were presents in 36.1% of patients, overall belonging to the AO type 13-C fracture pattern and to the group ≥85 years. CONCLUSION These study data seem to confirm our hypothesis that plate fixation for DHFs guarantees adequate fracture osteosynthesis and satisfactory functional outcomes at medium to long-term follow-up, not only in elderly patients, but also in octogenarian osteoporotic patients (≥85 years) with 13-C1 and 13-C2 fracture patterns, while an alternative solution should be considered for type C3 fractures, even in a primary trauma setting.

Intraoperative 3D imaging in the treatment of elbow fractures--a retrospective analysis of indications, intraoperative revision rates, and implications in 36 cases. BMC Med Imaging 2016; 16:24. [PMID: 26987661 PMCID: PMC4797343 DOI: 10.1186/s12880-016-0126-z] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2015] [Accepted: 03/14/2016] [Indexed: 11/12/2022] Open
Abstract
Background Three-dimensional (3D) imaging with a mobile C-arm has proven to be a valuable intraoperative tool in trauma surgery. However, little data is available concerning its use in the treatment of elbow fractures. The aim of the current study was to determine the intraoperative findings and consequences of 3D imaging in the treatment of elbow fractures. Methods Between 2001 and 2015, prospectively collected data of 36 patients who underwent intraoperative 3D imaging during elbow surgery were recorded. The findings and consequences of the intraoperative 3D scans were analyzed in a retrospective chart review. For clinical evaluation the analysis included the patients’ medical history, the injury pattern of the affected elbow and concomitant injuries. Intraoperative and postoperative complications and revision surgeries were evaluated as well. Results In 6 patients (16.7 %) analysis of the intraoperative 3D scan led to an immediate revision due to the detection of intra-articular screw placement (n = 3, 8.3 %) and remaining intra-articular step of >2 mm (n = 3, 8.3 %). In all of these patients, correct implant positioning and anatomical reduction could be achieved after immediate intraoperative revision, which was verified by a repeated intraoperative 3D scan. None of the 36 patients needed surgical revision based on postoperative radiological examinations due to secondary dislocation, wrong implant placement or remaining steps in the articular surface. Conclusions Intraoperative 3D imaging offers additional information about fracture reduction and implant positioning in the treatment of elbow fractures compared to conventional intraoperative 2D imaging. It may therefore reduce the need for revision surgery. The value of intraoperative 3D imaging for clinical outcomes still needs to be assessed.

Abstract
Background: The purpose of this study was to evaluate 30-day postoperative complications of open reduction and internal fixation [ORIF] and total elbow arthroplasty [TEA] for the treatment of distal humerus fractures in elderly patients using a validated national database. Methods: Review of the National Surgical Quality Improvement Program (NSQIP) Database identified all elderly patients (>65 years) who underwent TEA or ORIF for the treatment of closed intra-articular distal humerus fractures from 2007 to 2013. Bivariate and multivariate analyses of risk factors for 30-day adverse events as defined by NSQIP between ORIF and TEA groups were assessed using preoperative and intraoperative variables. Results: Among the 176 patients with distal humerus fractures, there were 33 TEA and 143 ORIF. There was no difference in age, medical comorbidities, or functional status. Total elbow arthroplasty was associated with an increased odds of severe adverse event compared to ORIF (odds ratio = 1.57, P = .16), although it did not achieve statistical significance. Infection rate was 0.7% in ORIF and 0.0% in TEA (P = .99). Insulin-dependent diabetes and functional status were significant independent predictors of postoperative adverse events. Operative time (165 minutes vs 140 minutes, P = .06) and postoperative length of stay (3.6 days vs 2.3 days, P = 0.03) were longer for TEA compared to ORIF. Conclusion: Open reduction and internal fixation and TEA have similar 30-day postoperative complications for the treatment of distal humerus fractures among elderly patients. Despite favorable trends for TEA in recent studies, additional clinical results are needed to understand complications and limitation of TEA. Level of evidence: Level III, prognostic study.

Abstract
AIM The purpose of this paper was to review the literature on the treatment of intra-articular fractures of the distal humerus in the elderly in order to evaluate the place for total elbow replacement (TER) in the light of our experience over the past 15 years. METHODS A review of the records of 11 consecutive patients over the age of 60 years who underwent primary TER for comminuted fractures of the distal humerus between 1997 and 2011 were reviewed and the surviving patients were interviewed. The Scopus database was used to perform a pragmatic review of the literature published between the mid-1990s and the present-day. RESULTS At the time of the most recent follow-up 3.5 years following surgery (range: 2-6 years) 7 patients assessed with the Mayo elbow performance index were classified as excellent, 4 were classified as good. There were no complications requiring further procedures encountered. Five surviving patients remain satisfied with the function of their TER. The number of papers recommending TER for treatment of these fractures continues to increase with time. CONCLUSIONS TER is now the treatment of choice for unreconstructable fractures of the distal humerus in the elderly. This option should therefore be available at the time of surgery for all distal humeral fractures in this patient population. A surgical approach other than olecranon osteotomy, which would preclude TER is therefore required.

Abstract
BACKGROUND Dynamic compression plate (DCP) constructs provide inadequate fixation in cases of poor bone quality and early weight-bearing. Screw locking elements (SLE) are flat locking nuts placed at the end of the screw to prevent screw stripping from the bone, improving fixation stability. The purpose of this work was to compare biomechanical and radiological evaluations of femoral ovine osteotomies fixed using DCP constructs with and without SLE. METHOD A dyaphyseal femoral osteotomy was performed in sixteen adult sheep and fixed with a DCP and cortical screws. Half of the animals were operated on with a SLE on each side of the osteotomy and the rest without the addition of SLE. Four animals of each group were euthanized after 8 weeks, and the remaining after 16 weeks. Both femora of each animal were radiographed and mechanically tested in torsion. RESULTS Radiologically femoral malalignment or screw loosening was observed in six out of the eight animals operated on without SLE. In contrast, all animals subjected to the operation with SLE showed complete radiological consolidation of the osteotomy. Seven of these eight animals showed normal femoral alignment and no osteosynthesis failure. Stiffness of the bones fixed with SLE was among 145% and 177% the value of their contralateral non-operated femurs (all animals of this group showed greater stiffness on the operated bone than its contralateral non-operated femur). However, stiffness of the bones operated on without SLE was among 58% and 87% the value of the stiffness of their contralateral non-operated bone (all animals of this group showed greater stiffness on the non-operated bone than the osteotomized ones). CONCLUSIONS Use of SLE avoided loosening of the system and stimulated stronger osteotomy consolidation. Clinical application of this improved system may thus be a feasible and cost-effective alternative to other more rigid and expensive bone fixation techniques.

Abstract
UNLABELLED Fractures of the distal humerus account for 5% of osteoporotic fractures in subjects older than 60 years. A history of osteoporosis, co-morbidities, and joint comminution make their management difficult. The therapeutic options are limited to functional treatments, osteosynthesis, or either partial or total arthroplasty. Functional treatment of distal humerus fractures in the elderly subject provide inconsistent results, often with persistence of pain with a stiff or unstable elbow. Osteosynthesis remains the reference treatment for these fractures, following the principle of stable and rigid osteosynthesis allowing early mobilization. However, joint comminution and a history of osteoporosis occasionally make it impossible to meet this objective, with a considerable rate of complications and surgical revisions. Total elbow arthroplasty remains an alternative to osteosynthesis with very satisfactory immediate results restoring a painless, stable, and functional elbow. These results seem reproducible and sustainable over time. The complication rate is not uncommon with an approximately 10% surgical revision rate. Elbow hemiarthroplasty remains to be validated in this indication. LEVEL OF EVIDENCE V.

Abstract
OBJECTIVE The objective of this study was to compare treatment results and complication rates between lateral and posterior approaches in surgical treatment of extra-articular distal humeral shaft fractures. MATERIAL AND METHODS Between June 2008 and May 2012, a total of 68 patients with extra-articular distal humeral shaft fractures were treated by lateral and posterior approaches. Of the patients, 30 were operated by a lateral approach (group I) and 26 patients were operated by a posterior approach (group II). There was no statistical significance between the two groups in sex distribution, age, the mechanism of the injury, injured arms, AO/ASIF (Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation) classification, and the time from injury to surgery (P>0.05). Operation time, intraoperative bleeding volume, hospitalisation, clinical outcomes, and complications were compared between the two groups. The elbow functional results were evaluated by the Mayo Elbow Performance Score (MEPS). RESULTS All patients were followed up. The average of follow-up in group I was 15.53±2.636 months (range, 12-22 months), and was 16.12±2.889 months (range, 12-22 months) in group II. There was no significant difference in the operation time, intraoperative bleeding time, and hospitalisation between the two groups (P>0.05). In group I, the mean time of bone union was 12.87±1.852 weeks (range, 10-16 weeks), the mean degrees of elbow flexion was 139.20°±3.274° (range, 134-146°), the mean degrees of elbow extension was 4.77°±1.906° (range, 0-8°), and the mean points of MEPS was 87.00±7.724 (range, 70-100 points). In group II, the mean time of bone union was 12.96±2.218 weeks (range, 10-16 weeks), the mean degrees of elbow flexion was 137.85°±4.076° (range, 130-145°), the mean degrees of elbow extension was 5.15°±2.327° (range, 0-9°), and the mean points of MEPS was 86.15±7.656 (range, 70-100 points). There was no significant difference in the bone union, range of elbow flexion, range of elbow extension and MEPS between the two groups (P>0.05). The overall complication rate in group I was lower than that in group II (P=0.041). CONCLUSIONS Both lateral and posterior surgical approaches acquired satisfied treatment results in the management of extra-articular distal humeral shaft fractures, and there was a lower complication rate using the lateral approach.
