Abstract
Articular fractures of the distal humerus are rare, and even rarer are fractures involving the trochlea and capitellum in a single fragment, with no associated comminution. These fractures are classified as 2a according to the Dubberley classification and are rarely described in the literature. Two cases of Dubberley 2a fractures were treated at our hospital. The first case, involving a 68-year-old patient, was treated with a medial and a lateral approach, combined with posteroanterior fixation using 3 Herbert screws. In the 2nd case, a 16-year-old male was treated with a single lateral approach, permitting fixation with two Herbert screws. One of the two screws is inserted into the bone at the edge of the cartilage, with an anteroposterior trajectory that leaves the cartilage intact. We opted mainly for posteroanterior screw fixation in subchondral bone, which is less damaging to articular cartilage and soft tissues and has already demonstrated its reliability. No associated lesions were found, and no complications were encountered. Results were excellent, with Mayo Elbow Performance Index (MEPI) scores of 95 and 100 respectively. Herbert screw fixation therefore appears to be an option of choice for these fractures, although comparative studies are needed to evaluate the different treatments available.

Abstract
Fractures around the elbow are often challenging to treat and in most cases require an extensive approach. Since the development of elbow arthroscopy, most authors have pointed out the potential advantages of a less invasive technique that can be useful for visualization and reduction of the articular fragments with an eventual percutaneous fixation. Arthroscopic techniques provide a limited exposure that may lead to a faster wound healing, lower rate of complications and thus, better recovery of range of motion. However, elbow arthroscopy is also a demanding technique, especially in a swollen and fractured joint, and it is not exempt of risks. The overall rate of complications has been rated from 1.5% to 11% and nerve injury rates from 1.26-7.5%.The objective of this review is to present the arthroscopic setup and general surgical technique for the management of elbow trauma and to define some clear indications. Patient positioning and operating room display is key in order to obtain success. In addition to the arthroscopic equipment, fluoroscopy is almost always necessary for percutaneous fixation and precise preparation is mandatory. In the last decade, literature regarding new portals or surgical tips for arthroscopic treatment of elbow fractures have been published.The main indications for fracture arthroscopic-assisted fixation are those articular fractures involving the coronoid, distal humerus shear fractures in the coronal plane (trochlear and capitellum fractures) and, more controversially, those affecting the radial head. The treatment of these type of fractures all arthroscopically is exponentially demanding as it might also require ligament repair. For coronoid fractures, it can be useful in Morrey type II and III, and O´Driscoll anteromedial facet fractures associated to a posteromedial instability pattern that also require a repair of the LCL. Although excellent results have been published, comparative series are scarce. Radial head fractures can also be approached arthroscopically in simple non-comminute fractures that can be fixed percutaneously.In conclusion, arthroscopy of the elbow is an excellent tool to better understand and visualize articular fractures of the elbow. However, despite the advances in surgical technique, whether it improves clinical and radiological results is still to be proven.

Abstract
Arthroscopic-assisted fracture fixation can be used for some adult elbow fractures. In particular, for articular fractures of the anterior elbow (coronoid/capitellum), elbow arthroscopy can provide excellent visualization of fracture fragments using a less invasive surgical exposure. Meticulous adherence to safe techniques and utilization of specialized equipment can help maximize safety and facilitate reproducible surgical results.

Abstract
Background Capitellum fractures are rare coronal fractures of the distal humerus which accounts for 6% of all distal humeral fractures and only 1% of all elbow fractures. The purpose of this study was to investigate the efficacy and complications of arthroscopically assisted reduction and fixation with absorbable screws for capitellar fracture of the humerus in children. Methods This was a retrospective case series study, which considered four patients (4 elbows), ranging from 10 to 15 years old, who were treated by arthroscopic-assisted percutaneous absorbable screw between 2018 and 2020. The elbow flexion-extension and forearm supination-pronation ranges of motion (ROM) were measured at the preoperative examination and last follow-up examination. Finally, the clinical and radiological results were assessed. Results The result of operations is satisfactory. The mean follow-up was 3.0 years (range 2-3.8 years). Average range of motion significantly improved from pre- to postoperation, with forearm supination from 60°(50°-60°) to 90°(90°) and pronation improved from 75°(70°-80°) to 90°(90°). The postoperative elbow flexion-extension range of motion was significantly higher compared with range of motion before surgery (P < 0.001; r = 0.949). At the final follow-up examination, the Mayo Elbow Performance Score was excellent. Satisfactory clinical results were achieved in all patients, and no postoperative complications were observed. Conclusions It is an effective and safe surgical option to use arthroscopic-assisted percutaneous absorbable screw fixation for treating capitellum fracture of the humerus without any complications in children. Level of evidence Level IV; case series.

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.

Abstract
BACKGROUND Fractures of the capitellum are uncommon and difficult to treat surgically. Capitellar open reduction-internal fixation uses a lateral open approach with posterior-to-anterior or anterior-to-posterior screw fixation. We investigated the use of an anterior portal for placement of anterior-to-posterior screw fixation through cadaveric measurement of the anatomic relationships from an anteriorly to posteriorly placed Kirschner wire (K-wire) to anterior elbow structures and calculated the percentage of articular surface accessed from the anterior portal. METHODS Eight fresh-frozen cadaveric elbows without radiographic or cutaneous evidence of prior trauma or surgery were used for this study. An arthroscopic proximal anteromedial portal was cannulized, and the radiocapitellar joint was evaluated. A single 1-cm portal was placed 1 cm distal to the elbow flexion crease and based lateral to the biceps tendon. The location of the portal was confirmed with a spinal needle, and blunt dissection with a hemostat was performed down to capsular tissue and for arthrotomy. A spinal needle sheath was threaded over a blunt switching stick and served as a cannula for placement of a 0.062 K-wire. Articular mapping was performed with cartilage scraping by the K-wire; the K-wire was then placed at the perceived center along the proximal-to-distal and radial-to-ulnar axis of the capitellum. Fluoroscopic confirmation of the wire's location was performed. Under loupe magnification, anatomic dissection was performed and the shortest distance measurements were recorded with digital calipers from the K-wire to the dissected structures. Capitellar articular measurements were recorded, in addition to the articular area defined by the K-wire. Data analysis was performed, and the average distance and standard deviation (in millimeters) were calculated. For structures that were pierced by or touching the K-wire, the distance was recorded as 0.1 mm. RESULTS The average distance from the K-wire to the radial, lateral antebrachial cutaneous, and median nerves was 1.8 mm, 11.5 mm, and 28.0 mm, respectively. The average distance from the median cubital vein and biceps tendon was 3.7 mm and 13.4 mm, respectively. The pin track pierced the brachioradialis and supinator muscles in all but 1 specimen. The average capitellar articular surface marked was 39.1% of the calculated articular footprint of the capitellum. CONCLUSIONS The anterior portal to the capitellum is directly adjacent to the radial nerve and lateral antebrachial cutaneous nerve, where each is susceptible to injury. We recommend blunt dissection and insertion of a cannula to allow drilling and placement of internal fixation in a relatively safe manner with respect to neurovascular structures.

Abstract
INTRODUCTION Open reduction and internal fixation (ORIF) of comminuted coronal shear fractures of the distal humerus is challenging. When a concomitant lateral condyle fracture is present, it may be used for a trans-fracture approach to facilitate exposure and fracture reduction. This study aimed to investigate the frequency of lateral condyle fractures in coronal shear fractures of the distal humerus and analyze fracture reduction, fracture union and clinical results following ORIF through a trans-fracture approach. MATERIALS AND METHODS All adult patients who underwent treatment for an acute distal humerus fracture during a three-year period in our level-one trauma center were identified. All fractures were classified according to the Orthopaedic Trauma Association (OTA/AO) fracture classification system and all B3 fractures were classified according to the Dubberley classification. B3 fractures with a concomitant radial condyle fracture were identified. The clinical and radiological results, (Mayo Elbow Performance Score = MEPS, Visual Analogue Scale = VAS, range of motion), complications and revision surgeries were analyzed. RESULTS 53 patients (mean age 52 ± 19 years) were identified. 13 fractures (24.5%) were B3 fractures. Four of them (30.8%) had a concomitant radial condyle fracture. All of these patients underwent ORIF with headless cannulated compression screws and a (postero-)lateral locking plate through a trans-fracture approach. At a minimum follow-up of 24 months, the MEPS was 88 ± 12 points, the VAS was 2 ± 1 and the range of motion was 118° ± 12°. All fractures showed anatomic reduction. One patient developed partial avascular necrosis and underwent arthrolysis at 6 months. One patient underwent partial hardware removal and lateral collateral ligament bracing at 6 months. CONCLUSIONS Lateral condyle fractures are present in about one third of coronal shear fractures of the distal humerus. This injury can be used for a trans-fracture approach to facilitate exposure and to reliably achieve anatomic fracture reduction.

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
Introduction We evaluated the clinical and radiological outcomes of capitellar fractures treated with modified screw insertion (inserting the first fixation screw anteroposteriorly and the second screw posteroanteriorly), a technique that can be applied with a minimally invasive lateral elbow approach. Materials and Methods Twenty-one isolated capitellum fractures that were surgically treated were included in the study. Fixation was achieved with two headless cannulated compression screws placed in anteroposterior and posteroanterior order using the modified lateral elbow approach. The Broberg-Morrey rating system was used to assess the post-operative functional status of the patients. Results According to the Broberg-Morrey criteria, the mean score was 92.7 (77-100) and 13 cases had excellent, 7 had good, and 1 had fair results. None of the patients developed avascular necrosis or heterotopic ossification. According to the Broberg-Morrey arthrosis score, two cases had Grade 1 and one had Grade 2 arthrosis. One patient had a superficial wound site infection that was treated with antibiotics, and in one case a 60° extension loss was observed in the elbow. Conclusion Treatment of isolated capitellar fractures with 2 headless screws placed anteroposteriorly and posteroanteriorly can provide stable fixation and is less traumatic for the elbow joint.

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
BACKGROUND Coronal shear fractures of the distal humerus are rare injuries and are technically challenging to manage. Open reduction and internal fixation (ORIF) has become the preferred treatment because it provides anatomical reduction, stable internal fixation, and early motion, but the optimal surgical approach remains controversial.
CASE SUMMARY We report three cases of coronal shear fractures of the distal humerus treated successfully by ORIF via a novel surgical approach, in which lateral epicondyle osteotomy was performed based on the extended lateral approach. We named the novel surgical approach the lateral epicondyle osteotomy approach. All patients underwent surgical treatment and were discharged successfully. All patients had excellent functional results according to the Mayo elbow performance score. The average range of motion was 118° in flexion/extension and 172° in pronation/ supination. Only case 2 had a complication, which was implant prolapse.
CONCLUSION We demonstrated that the lateral epicondyle osteotomy approach in ORIF is effective and safe for coronal shear fractures of the distal humerus.

Abstract
Several articles have described arthroscopic fixation of coronal shear fractures of the distal humerus. However, not all of them have used purely arthroscopic techniques. In this Technical Note we describe another technique for intra-articular distal humeral fracture fixation using arthroscopy alone. Standard proximal anteromedial, proximal anterolateral, and posterolateral viewing portals are established with soft spot portal for reduction. During intra-articular examination, the fragment involving the capitellum and the trochlea as 1 piece is detected. Closed manipulative reduction under anesthesia is conducted with distraction, varus force, and gradual elbow extension. After closed reduction, reduction of the fragment more precisely under arthroscopic visualization using probe and elevator is performed. The fragment is temporarily fixed using 2 Kirschner wires from posterior direction. Anatomic reduction is confirmed with an image intensifier. Screw guide pin is inserted posteroanteriorly under image intensification, and a headless compression screw is placed over each wire. We describe a safe, reproducible, and minimal invasive technique for the arthroscopic treatment of coronal shear fractures of the distal humerus.

Abstract
Background To determine interobserver agreement in the classification by X-rays and by computed tomography (CT) scan of the coronal shear fractures of the capitellum and trochlea as well as the agreement between these two tests. Methods Patients with coronal shear fractures of the capitellum who were managed at our center between January 2008 and December 2017 were included. This retrospective cohort study was carried out with the approval of the ethics committee of our institution (Nº: IIBSP-Cod-2019-02, Ref. 19/070). Clinical, radiographic, and elbow-specific outcomes, including the Mayo Elbow Performance Index, were evaluated. Three observers analyzed the preoperative X-rays from all the cases. Each one of them independently classified the fractures according to the Bryan and Morrey classification (with the modification of McKee et al). The interobserver agreement was calculated by Cohen kappa coefficient. The same methodology was used to analyze the CT scan. Thereafter, one single value was determined for each X-ray and CT scan, from the good interobserver agreements. Finally, the agreement between the global X-ray classification and the global CT scan classification was calculated using the agreement percentage and the Cohen kappa coefficient. Results There were 3 males and 6 females, with a mean age of 47 years (range, 18-83). The mean follow-up period was 18 months (12-40). The average Mayo Elbow Performance Index score was 85 (range, 65-100) points. The complications were nonunion in one patient (11 %), degenerative arthritis in 7 (78 %), joint step-off in 5 (55%), and heterotopic ossification in 7 (78%). The agreement analysis between the global X-ray classification and the global CT scan classification showed a 57.1% agreement, with a kappa coefficient of −0.167. These values imply the absence of agreement. Conclusion Our results demostrated that simple X-rays do not allow for the adequate interpretation of distal humeral coronal plane fractures. Although an acceptable interobserver agreement was found, there is no agreement when the same fractures were analyzed by CT scan. The authors routinely recommend CT scan to assess the extent of the fracture and perform surgical planning.

Abstract
OBJECTIVE This study aimed to evaluate the functional outcomes of the surgical treatment performed with a buttress plate for the trochlear and distal capitellum fractures with posterior extension in the humerus. METHODS The data belonging to 6 female and 4 male patients with a mean age of 43.8±11.1 (34-72) years were retrospectively evaluated. The mean follow-up period was 59.6±38.79 (22-127) months. The trochlear extension and posterior comminution of the fractures were assessed through the initial X-rays and computerized tomography images. Ten patients were classified as Dubberley type B. All fractures were treated surgically, with open reduction and internal fixation using a lateral buttress plate, headless cannulated screws, and Kirschner (K)-wires. The passive flexion and extension exercises were initiated at the first postoperative day. The patients were evaluated clinically and radiographically at the final follow-up. The outcomes were quantified using the Mayo Elbow Performance Index (MEPI), visual analog scale (VAS) pain score, and the patient's opinion. RESULTS At the final follow-up, the mean elbow flexion was 137.5°±3° (132°-140°), extension was -17.9°±9.2° (10°-35°), pronation was 72.2°±2.6° (68°-75°), and supination was 78.9°±4.09 (72°-85°). The mean MEPI score was calculated as 95.5±5.98 (85-100). According to the MEPI score, 8 patients were evaluated as excellent and 2 as good. The mean VAS pain score was 0.8±1.03 (0-2). The subjective patient evaluation was recorded as excellent in 5 patients, good in 3 patients, and moderate in 2 patients. One patient developed avascular necrosis and 2 patients had elbow joint arthrosis. K-wire migration was observed in one patient. Loss of reduction, nonunion, malunion, reflex sympathetic dystrophy, or heterotopic ossification were not encountered. CONCLUSION The management of distal humeral fractures is challenging, and favorable outcomes are closely associated with early joint motion. A solid fixation grants early mobilization. An internal fixation using lateral buttress plate, headless cannulated screws, and interfragmentary K-wires provides a solid and secure construction that allows early postoperative joint motion.

Abstract
Coronal shear fractures of the distal humerus are a unique subset of distal humeral fractures which entail partial or complete articular fractures of the distal humerus without involvement of the columns. The very distal nature of these fragments, their small size and propensity for comminution render them challenging to treat surgically. The purpose of this article is to describe the classification, outcomes and surgical techniques currently used for the treatment of these fractures using the available literature and authors' clinical experience.

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.

Abstract
SUMMARY OBJECT: To explore the treatment effect of the anterior medial neurovascular interval approach to coronal shear fractures of the distal humerus. METHODS: This prospective study included two female patients who were 30-64 years old, with a mean age of 47 years. Fractures were caused by falling from a bicycle. The time between the injury and operation was 1-2 days, with a mean time interval of 1.5 days. Two patients with coronal shear fracture of the distal humerus were treated with open reduction and internal fixation using anterior neurovascular interval approach. RESULTS: There were no intraoperative and postoperative neurological and vascular complications or infections, and the fracture was united. At 12 months after the surgery, the patient returned to work without pain, and with a normal range of motion for elbow and forearm rotation. The X-rays revealed excellent fracture union, no signs of heterotopic ossification, and no traumatic arthritis. According to Mayo's evaluation standards for elbow function, a score of 100 is excellent. CONCLUSIONS: The application of the anterior neurovascular interval approach of the elbow in the treatment of shear fracture of the articular surface of the distal humerus, particularly the trochlea of the humerus, can reduce the stripping of the soft tissue.

Abstract
OBJECTIVE Fractures involving the capitellum can be treated surgically by excision of the fragment, or by reduction and internal fixation with screws, with or without heads. The lateral Kocher approach is the most common approach for open reduction. We believe that the limited anterior approach of the elbow, could be a valid technique for treating these fractures, as it does not involve the detachment of any muscle group or ligament, facilitating the recovery process. MATERIAL AND METHOD A description is presented of the surgical technique, as well as of 2cases with a Bryan-Morrey type 1 fracture (Dubberley type 1A). Two different final quality of life evaluation questionnaires were completed by telephone: the EuroQol Five Dimensions Questionnaire (EQ-5D), and the patient part of the Liverpool Elbow Score (PAQ-LES) questionnaire. RESULTS The 2patients showed favourable clinical progress at 36 and 24 months, respectively, with an extension/flexion movement arc of -5°/145° and -10°/145°, as well as a pronosupination of 85°/80° and 90°/90°. The 2patients showed radiological consolidation with no signs of osteonecrosis. The EQ-5D score was 0.857 and 0.910 (range: 0.36-1), and a PAQ-SLE of 35 and 35 (range: 17-36), respectively. CONCLUSIONS We believe that the limited anterior approach of the elbow is a technical option to consider for the open surgical treatment of a capitellum fracture, although further studies are needed to demonstrate its superiority and clinical safety compared to the classical lateral Kocher approach.

Abstract
Coronal shear fractures of distal humerus involving the capitellum and the trochlea are rare injuries with articular complexity, and are technically challenging for management. With better understanding of the anatomy and imaging advancements, the complex nature of these fractures is well appreciated now. These fractures involve metaphysealcomminution of lateral column and associated intraarticular injuries are common. Previously, closed reduction and excision were the accepted treatment but now preference is for open reduction and internal fixation with an aim to provide stable and congruent joint with early range of motion of joint. Various approaches including extensile lateral, anterolateral and posterior approaches have been described depending on the fracture pattern and complexity. Good to excellent outcome have been reported with internal fixations and poor results are noted in articular comminution with associated articular injuries. Various implants including headleass compression screws, minifragment screws, bioabsorbable implants and column plating are advocated for reconstruction of these complex fractures. Inspite of articular fragments being free of soft tissue attachments the rate of osteonecrosis and osteoarthritis is reported very less after internal fixation. This article summarizes the diagnostic and treatment strategies for these rare fractures and recommendations for management.

Abstract
Several types of elbow fractures are amenable to arthroscopic or arthroscopic-assisted fracture fixation, including fractures of the coronoid, radial head, lateral condyle, and capitellum. Other posttraumatic conditions may be treated arthroscopically, such as arthrofibrosis or delayed radial head excision. Arthroscopy can be used for assessment of stability or intra-articular fracture displacement. The safest portals are the midlateral (soft spot portal), proximal anteromedial, and proximal anterolateral. Although circumstances may vary according to the injury pattern, a proximal anteromedial portal is usually established first. Arthroscopy enables a less invasive surgical exposure that facilitates visualization of the fracture fragments in select scenarios.

Abstract
Fractures of the capitellum and trochlea account for a small proportion of elbow trauma. Clinicians need to be vigilant in their assessment as they are commonly associated with other injuries about the elbow. To optimize outcomes, the goals of management include a stable, anatomic reduction and early range of motion. Closed reduction of noncomminuted fractures may be successful but requires close follow-up. Open reduction and internal fixation is the preferred management of displaced capitellum-trochlear fractures. Elbow stiffness is the most commonly reported complication in operatively treated fractures. Arthroscopic-assisted reduction and internal fixation and arthroplasty are evolving management options.

Abstract
Coronal shear fractures of the distal humerus are rare, complex fractures that can be technically challenging to manage. They usually result from a low-energy fall and direct compression of the distal humerus by the radial head in a hyper-extended or semi-flexed elbow or from spontaneous reduction of a posterolateral subluxation or dislocation. Due to the small number of soft tissue attachments at this site, almost all of these fractures are displaced. The incidence of distal humeral coronal shear fractures is higher among women because of the higher rate of osteoporosis in women and the difference in carrying angle between men and women. Distal humeral coronal shear fractures may occur in isolation, may be part of a complex elbow injury, or may be associated with injuries proximal or distal to the elbow. An associated lateral collateral ligament injury is seen in up to 40% and an associated radial head fracture is seen in up to 30% of these fractures. Given the complex nature of distal humeral coronal shear fractures, there is preference for operative management. Operative fixation leads to stable anatomic reduction, restores articular congruity, and allows initiation of early range-of-motion movements in the majority of cases. Several surgical exposure and fixation techniques are available to reconstruct the articular surface following distal humeral coronal shear fractures. The lateral extensile approach and fixation with countersunk headless compression screws placed in an anterior-to-posterior fashion are commonly used. We have found a two-incision approach (direct anterior and lateral) that results in less soft tissue dissection and better outcomes than the lateral extensile approach in our experience. Stiffness, pain, articular incongruity, arthritis, and ulnohumeral instability may result if reduction is non-anatomic or if fixation fails.

BACKGROUND Coronal plane fractures of the distal humerus have special characteristics in classification, imaging, surgical approaches, materials used, treatment modalities, and complications. The purpose of this study is to comment on these topics. MATERIALS AND METHODS A retrospective analysis was done for patients with distal humeral coronal plane fractures. They were classified according to Dubberley and functionally evaluated by Mayo Elbow Performance Index (MEPI). The long-term complications were evaluated. RESULTS There were 15 patients, with type 1 fractures in 2, type 2 in 6, and type 3 in 7. All patients were treated by open reduction and internal fixation either by lateral or posterior approach. The average MEPI score was 83.3 (range, 60-100) points with 7 excellent, 2 good, and 6 fair results. The MEPI scores of type 3 fractures were significantly lower than those of types 1 and 2 fractures (P = .037 and P = .002, respectively). The complications were avascular necrosis in 4 (27%) patients, degenerative arthritis in 6 (40%), joint step-off in 6 (40%), heterotopic ossification in 7 (47%), nonunion in 1 (7%), and implant failure in 1 (7%). The presence of avascular necrosis and joint step-off were significantly associated with degenerative arthritis (P = .004 and P = .005, respectively). Heterotopic ossification was significantly associated with presence of lateral epicondyle fracture (P = .004). CONCLUSION Type 1A and 2A coronal plane fractures typically had an excellent outcome. However, type 3 and subtype B fractures are prone to developing complications which are primarily avascular necrosis, degenerative arthritis and heterotopic ossification.

Abstract
PURPOSE This study was conducted to evaluate reports of clinical outcomes of isolated capitellar fractures. MATERIALS AND METHODS We conducted a systematic review of medical databases reporting clinical outcomes of patients undergoing nonoperative and operative management of isolated capitellar fractures. RESULTS We identified 28 studies for inclusion comprising 174 patients. All included studies were level IV evidence. Capitellar fractures were more common among women than men and were more likely to involve the nondominant arm. Type I fractures (84%) were more common than type II (14%) and III fractures (2%). Operative and nonoperative management both led to satisfactory clinical outcomes. No significant difference in outcomes was observed in those undergoing operative management compared with those undergoing closed reduction and immobilization. CONCLUSIONS Nonoperative and operative management of isolated capitellar fractures leads to satisfactory clinical outcomes as determined by postoperative range of motion, improvement in pain, and a return to previous levels of function. No statistical difference in outcomes was observed between those undergoing operative management compared with those treated with closed reduction and immobilization.

Abstract
Management of coronal shear fractures of the distal humerus has evolved considerably over the past 3 decades, with an increased appreciation of the complexity of these fractures, improvements in internal fixation techniques, and the use of more extensile exposures. Nearly all of these fractures are displaced, given the paucity of soft tissue attachments and correspondingly, nonsurgical management is fraught with complications including chronic pain, mechanical symptoms, and instability and is not recommended. Good to excellent outcomes can be achieved in the majority of patients with open reduction internal fixation, particularly when the fracture is limited to the radiocapitellar joint. Outcomes are worst for those with considerable medial extension or comminution. Computed tomography is highly recommended to guide surgical planning. The presence of posterior comminution or extension to the medial column might require more extensile exposures and supplemental fixation for adequate stability. Arthroscopic reduction and fixation techniques have been described for the simple fracture. Those not amenable to fixation might do better with total elbow arthroplasty in a select population. Long-term data demonstrate the durability of these elbows following open reduction internal fixation. Complications other than stiffness are rare. Radiographic avascular necrosis does not appear to affect outcome. Radiographic mild to moderate arthritis was observed in half of patients at 17-year follow-up.
