Abstract
BACKGROUND Distal humerus elbow fractures are one of the most common traumatic fractures seen in pediatric patients and present as three main types: Supracondylar (SC), lateral condyle (LC), and medial epicondyle (ME) fractures. AIM To evaluate the epidemiology of pediatric distal humerus fractures (SC, LC, and ME) from an American insurance claims database. METHODS A retrospective review was performed on patients 17 years and younger with the ICD 9 and 10 codes for SC, LC and ME fractures based on the IBM Truven MarketScan® Commercial and IBM Truven MarketScan Medicare Supplemental databases. Patients from 2015 to 2020 were queried for treatments, patient age, sex, length of hospitalization, and comorbidities. RESULTS A total of 1133 SC, 154 LC, and 124 ME fractures were identified. SC fractures had the highest percentage of operation at 83%, followed by LC (78%) and ME fractures (41%). Male patients were, on average, older than female patients for both SC and ME fractures. CONCLUSION In the insurance claims databases used, SC fractures were the most reported, followed by LC fractures, and finally ME fractures. Age was identified to be a factor for how a pediatric distal humerus fractures, with patients with SC and LC fractures being younger than those with ME fractures. The peak age per injury per sex was similar to reported historic central tendencies, despite reported trends for younger physiologic development.

Abstract
Medial humeral epicondyle fractures are seen in about one-fourth of all elbow fractures in the pediatric population. Though it seems to be a common occurrence, there is still controversy existing on the treatment aspects to date. Among these fractures, about one-fourth are seen incarcerated into the elbow joint and this is managed surgically. This is a case report of an adolescent male who had a medial epicondyle fracture of the humerus with the fracture fragment incarcerated into the elbow joint, and the patient also had ulnar nerve palsy, He was surgically treated with screw fixation and had an uneventful intra-operative and post-operative period.

Abstract
Purpose Medial epicondyle fractures are among the most common pediatric elbow injuries. The management of these fractures continues to be debated. To better understand patient results with operative fixation, we reviewed the outcomes of operatively treated medial epicondyle fractures. Methods A retrospective review was performed to identify all patients less than 18 years of age at the time of injury who were treated surgically for medial epicondyle fractures. Outcomes were assessed based on the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity and Pain Interference domains, Visual Analog Scale for pain, subjective range of motion, ulnar nerve function, and requirement for secondary surgery. Results We identified a cohort of 95 patients treated for a medial epicondyle fracture with open reduction and screw fixation. Of these, 39 patients with a mean age of 12.2 years (SD, 2.2 years; range, 7.6–16.0 years) at surgery were assessed for an average follow-up of 6.3 years (SD, 3.2 years; range, 2.2–13.9 years). Outcome measures and pain scores were excellent. The mean PROMIS Upper Extremity score was 56.9, the mean Pain Interference score was 38.5, and the mean Visual Analog Scale score was 0.4.Sixteen patients (41%) required secondary surgery for symptomatic hardware removal. Seven patients (18%) developed sensory complaints and 2 (5%) developed motor complaints consistent with ulnar nerve irritability. Three patients (8%) reported dissatisfaction with elbow range of motion. Patients who required secondary surgeries had higher (worse) PROMIS Pain Interference scores. Conclusions At an average of 6.3 years after surgery, the clinical outcomes for medial epicondyle fracture were excellent. While operative treatment for medial epicondyle fractures in children leads to excellent clinical outcomes, patients and surgeons should be aware of high rates of hardware removal.

Abstract
BACKGROUND Screw fixation is the most commonly employed fixation strategy for displaced medial epicondyle fractures, but in younger patients with minimal ossification, the fracture fragment may not accommodate a screw. In these situations, Kirschner-wires (K-wire) or suture anchors may be utilized as alternatives. The purposes of this study were to examine the biomechanical properties of medial epicondyle fractures fixed with a screw, K-wires, or suture anchors, to evaluate clinical outcomes and complications of patients 10 years of age or younger treated with these approaches, and to perform a cost-analysis. METHODS Biomechanical assessment: Immature pig forelimbs underwent an osteotomy through the medial epicondyle apophysis, simulating a fracture. These were then fixed with a screw, K-wires or suture anchors. Cyclic elongation (mm), displacement (mm), load to failure (N), and stiffness (N/mm) were assessed. Clinical assessment: a retrospective review was performed of patients 10 years of age or younger with a medial epicondyle fracture fixed with these strategies. Radiographic outcomes, postoperative data and complications were compared. These data were used to perform a cost-analysis of each treatment approach. RESULTS Biomechanically, screws were stronger (P=0.047) and stiffer (P=0.01) than the other constructs. Clinically, 51 patients met inclusion criteria (screw=27, wires=11, anchor=13). Patients treated with K-wires were younger (P<0.05) and patients treated with screw fixation had a shorter casting duration (P=0.008). Irrespective of treatment strategy, all fractures healed (100%) and only 1 patient in the screw group lost reduction. Clinical outcomes and complications were similar between groups, but the suture anchor group was less likely to require a second surgery for implant removal (P<0.05). This lower reoperation rate led to a cost-saving of 10%. CONCLUSIONS Biomechanically, all 3 approaches provided initial fixation exceeding the forces observed across the elbow joint with routine motion. The screw construct was the strongest and stiffest. Clinically, all 3 strategies were acceptable, with screw fixation offering a shorter casting duration, but greater implant removal need with higher associated costs.

Abstract
BACKGROUND There remains controversy surrounding the treatment of pediatric medial epicondyle fractures. This systematic review examines the existing literature with the aim to elucidate optimal management strategies. METHODS A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was executed. All data collection was completed by August 01, 2018. Functional outcomes, diagnostic imaging, athlete management, union rates, ulnar nerve symptoms, surgical methods, surgical positioning, and posttreatment protocols were categorized and recorded. Frequency-weighted mean values were calculated with associated SDs. RESULTS Thirty-seven studies with 1022 patients met the inclusion criteria. Functional outcomes for patients were mostly good following operative and nonoperative management. The most common complication was a slight loss of elbow extension (7.6±5.9 degrees) and flexion (13.3±5.8 degrees). Operative treatment was associated with higher union rates than nonoperative management (700/725, 96% vs. 69/250, 28%; P<0.001). Standard diagnostic imaging techniques to measure displacement were unreliable with a newly proposed axial view having high inter-rater and intrarater reliability. The most common surgical method used was open reduction and internal fixation with Kirschner wires. Whereas surgical management of patients with associated ulnar nerve symptoms led to symptom resolution, nonoperative management occasionally led to the development of these symptoms. Elbow range of motion was initiated at ~2.8±1.4 (range, 0 to 8 wk) weeks after surgery and 3.4±1.2 (range, 3 to 5 wk) weeks without surgery (P<0.001). CONCLUSIONS Although there is still no consensus on treatment of pediatric medial epicondyle fractures, both operative and nonoperative approaches result in good outcomes. LEVEL OF EVIDENCE Level IV-therapeutic.

Abstract
Background and aim of the work: Medial epicondyle fractures of the humerus account for 11–20% of all elbow injuries in children and in 30–55% of cases they are associated with an elbow dislocation. Undisplaced fractures are usually treated conservatively but literature is controversial regarding the treatment of displaced fractures (≥5mm) in paediatric fractures. In recent years, there is an emerging consensus that such patients may benefit more from open reduction and internal fixation. Authors report a case of a 15 years old nonprofessional soccer player who suffered of an elbow dislocation with an intra-articular fragment derived from avulsion of the medial epicondyle. Methods: Clinical and instrumental evaluation confirmed elbow dislocation with an intra-articular fragment derived of the medial epicondyle. After the reduction an open reduction and internal fixation with cannulated screw was performed. Results: Clinical evaluation after 90 days showed resolution of pain and almost complete ROM and complete recovery of strength and of functionality of the operated limb. Furthermore, x-rays demonstrated consolidation of the fracture. Conclusions: this case confirms that a precise evaluation of the fracture and its displacement is at the base of satisfactory outcomes. If fracture is displaced ≥5mm and patient is near skeletal maturity open reduction and fixation is indicated. (www.actabiomedica.it)

Abstract
Medial epicondyle fractures are the 3rd most common pediatric elbow fractures. Regardless of treatment method, some degree of elbow motion loss has been reported. The purpose of our study was to determine the relationship between the amount of anterior fracture displacement and loss of elbow passive extension in an adult cadaveric medial epicondyle fracture model. Fifteen fresh frozen adult cadavers were procured to create fracture models at scenarios of 2, 5, 10 mm, and maximum displacement. Terminal elbow extension was recorded for each cadaveric model at each fracture scenario. A linear mixed model regression analysis was used to test the association between fracture displacement and loss of terminal elbow passive extension. At 2 mm of displacement, the average loss of terminal extension was 3.89°; at 5 mm, it was 7°; at 10 mm, it was 10.7°; at maximum displacement (~15 mm), it was 17°. A statistically significant positive linear association between fracture displacement and loss of terminal elbow extension was observed (5 mm of displacement = loss of ~4.7°). In our fracture model, when the medial epicondyle displaced anteriorly, we noticed a change in the tension of the medial collateral ligaments which lead to a decrease in terminal elbow extension. However, this only contributed partially to the loss of motion observed clinically in the literature. Even though our findings did not support the recommendation of surgical intervention to prevent loss of elbow motion in medial epicondyle fractures, we still encourage physicians to consider the consequence of displacement and its potential influence of elbow range of motion.

Abstract
Medial epicondyle fracture nonunions of the elbow may lead to symptomatic instability in the high-demand or overhead athlete. These injuries are challenging to treat surgically because of the small residual bony fragment, the scarred and shortened chronically injured ulnar collateral ligament (UCL), which prevents it from being mobilized and reduced to its native position. To date, most described methods aim at reducing the displaced fragment and achieving union with the humerus. This usually can only be accomplished by releasing of the scarred UCL to mobilize the fragment. The scarred and attenuated residual ligament is then repaired to restore stability but is often inadequate to sustain high-level valgus loads. We describe a technique of excision of the bony fragment and UCL reconstruction with allograft, augmented with internal brace to provide medial stability to the elbow. The described method allows proper tensioning of the graft and provides immediate and secure fixation.

Radiological, clinical and functional evaluation using the Quick Disabilities of the Arm, Shoulder and Hand questionnaire of children with medial epicondyle fractures treated surgically. INTERNATIONAL ORTHOPAEDICS 2017; 41:1447-1452.

Abstract
PURPOSE The main goal of this study was to retrospectively evaluate the clinical, functional and radiographic outcomes of displaced medial epicondyle fractures with or without associated elbow dislocation in children undergoing surgical treatment and to evaluate upper-extremity function with the Quick Disbilities of the Arm, Shoulder and Hand (Quick DASH) questionnaire. The hypothesis was that patients with associated elbow dislocation would have similar functional outcome to patients with displaced fractures with or without intra-articular entrapment of the medial epicondyle. METHODS A review of medical charts was performed to identify all children and adolescents who underwent surgical treatment for displaced medial epicondyle humeral fractures managed at a single institution. Patients with a closed fracture on plain radiographs, presence of growth cartilages and managed surgically were included in the study. Fractures were radiologically assessed on anteroposterior and lateral radiographs and rated according to Papavasiliou and Crawford classification. Functional outcome was measured with the Quick DASH questionnaire. Sixty-six patients met inclusion criteria, and 38 children presented with isolated displaced medial epicondyle fracture (Group A: type II and type III) and 28 with medial epicondyle fractures associated with elbow dislocation (Group B: type IV). RESULTS The Papavasiliou and Crawford system classified 36 fractures as type II (54.6%), two (3%) as type III and 28 as type IV (42.4%). All patients underwent open reduction. Fracture fixation was performed with K-wires in 26 (35%) children and a with single screw in 40 (65%). Mean follow-up was 37.5 months (range, 12-68). Overall complication rate was 18%. In particular, three adverse events (3/38, 8%) were recorded in Group -A and nine (9/28, 32%) in Group B (p = 0.003). Mean Quick DASH score at final follow-up was 4.6 ± 3.8 (range, 0-15.9) and was not significantly different between Groups A (5.4 ± 4.3; range, 0-15.9) and B (4.1 ± 3.5; range, 0-15.9) (p > 0.05). CONCLUSIONS Children with type II, III and IV medial epicondyle fractures undergoing surgical treatment have good radiological, clinical and functional outcome but warrant special attention to detect intra-articular entrapment of the broken epicondyle. In these cases, both patient and family should be warned of the potential risk of loss of elbow range of motion and possibly poor functional outcome, especially if treatment is delayed.

Abstract
We present a new bone suture anchor technique for fractures of the medial epicondyle. The hypothesis was that the results would be similar to those with the divergent K-wire fixation. This retrospective study included 40 patients who presented with displaced fractures of the medial epicondyle: one group was treated with a Mitek(®) non-resorbable bone suture anchor (group A: n=21), the other by K-wire fixation (group B: n=19). A medial approach was taken with an anchor placed above the olecranon fossa. The epicondyle was then repositioned by bone suture. After a mean follow-up of 18.6 months, union was obtained in all epicondyles. There was no difference in flexion-extension of the elbow. The rate of hypertrophy of the medial epicondyle was similar in both groups (57%). The bone suture anchor of the medial epicondyle is an effective technique that does not require hardware removal and is an alternative treatment option to divergent K-wire fixation.

Abstract
In caring for athletes, the physician must be able to accurately diagnose and appropriately treat all forms of elbow injuries. Traumatic injuries to the elbow are common in the athlete. The late cocking phase of throwing produces tremendous valgus stress on the elbow that can lead to medial epicondyle avulsion fractures in adolescents or rupture of the medial ulnar collateral ligament in skeletally mature overhead throwers, such as baseball pitchers and javelin throwers. Common traumatic elbow injuries suffered by athletes, surgical techniques for operative repair of these injuries, as well as postoperative rehabilitation protocols and the clinical results are presented.

Abstract
Background Intra-articular incarceration of the epicondylar fragment occurs in 5–18 % of all cases of medial epicondyle fracture. It requires stable fixation to allow early motion, since elbow stiffness is the most common complication following medial epicondyle fracture. In this retrospective study, we report the clinical and functional outcomes and the complications that occurred following open reduction and screw fixation of medial epicondyle fractures with intra-articular fragment incarceration. Methods Thirteen children who had a fracture of the medial epicondyle with incarceration of the fragment in the elbow joint (type III) were surgically treated in our university hospital between 1998 and 2012. There were eight male and five female patients. The mean age at the time of injury was 13 years (range 9–16). Operative treatment consisted of open reduction and internal fixation with one or two 4.0-mm cannulated screws under fluoroscopic control. Results All of the patients were clinically reviewed at an average follow-up of 29 months. The overall range of motion limitation was about 5° for flexion–extension and 2° for pronation–supination. The score was excellent in all patients (mean 96.3). Complications occurred in four (31 %) children: two cases of symptomatic screw head prominence, irritation with partial lesion of the distal triceps myotendinous junction in one patient, and median nerve entrapment syndrome in one patient. Conclusions In conclusion, open reduction and screw fixation yielded excellent clinical and functional outcomes for the treatment of medial epicondyle fractures with intra-articular fragment incarceration. However, particular attention is should be paid when treating these potentially serious injuries in order to minimize the risk of possible complications. Level of evidence Therapeutic IV.

Abstract
Injuries of the medial epicondyle are relatively common, mostly affecting children between 7 and 15 years. The anatomical characteristics of this apophysis can make diagnosis difficult in minimally displaced fractures. In a small percentage of cases, the fractured fragment may occupy the retroepitrochlear groove. The presence of dysesthesias in the territory of the ulnar nerve requires urgent open reduction of the incarcerated fragment. A case of a seven-year-old male patient is presented, who required surgical revision due to a displaced medial epicondyle fracture associated with ulnar nerve injury. A review of the literature is also made.

Abstract
BACKGROUND Medial humeral epicondyle fracture displacement in children is difficult to quantify, as current methods suffer from significant intraobserver and interobserver variability. The aim of this study was to create a systematic approach to determine medial epicondyle fracture displacement based upon easily identifiable radiographic landmarks of the elbow. METHODS In this anatomic descriptive study, we evaluated 171 anteroposterior (AP) and lateral radiographs from children (4 to 15 years old) with a normal distal humerus. On the AP radiograph, the center of the medial epicondyle was compared with a line based upon the inferior olecranon fossa. On the lateral radiograph, the center of the medial epicondyle was compared with the posterior humeral line. RESULTS On the AP radiograph, the average location of the center of the medial epicondyle was 0.5 mm inferior to the olecranon line (SD, 2.0 mm). On the lateral radiograph, the average location of the center of the medial epicondyle was 1.2 mm anterior to the posterior humeral line (SD, 1.2 mm). CONCLUSIONS Our findings demonstrated a consistent radiographic position of the medial humeral epicondyle with little variation throughout skeletal maturation. CLINICAL RELEVANCE This study may be helpful in assessing fracture displacement in pediatric medial epicondyle fractures.

Abstract
PURPOSE Displaced medial humeral epicondyle fractures with or without elbow dislocation have been treated with open reduction and fixation using K-wires or screws. The purpose of this study is to evaluate the clinical and radiological outcomes of surgical treatments of medial humeral epicondyle fracture without elbow dislocation according to the fixation methods. MATERIALS AND METHODS Thirty-one patients who had undergone open reduction and fixation of the displaced medial humeral epicondyle fracture without elbow dislocation were included. Group I consisted of 21 patients who underwent fixation with K-wires, and Group II comprised 10 patients who underwent fixation with cannulated screws. Immediate postoperative, final follow- up and normal anteroposterior radiographs were compared and the clinical outcome was assessed using the final Japanese Orthopaedic Association (JOA) elbow assessment score. RESULTS On the immediate postoperative radiographs, the distal humeral width in Group II was larger than that in Group I. On the final follow-up radiographs, the epicondylar position in Group I was lower than that in Group II. There was no significant difference in the distal humeral width, epicondylar position and joint space tilt between the immediate postoperative, final follow-up radiographs and the normal side within each group. There was no significant difference in the final JOA score between groups. CONCLUSION Open reduction followed by K-wire fixation or screw fixation of the displaced medial humeral epicondyle fracture without elbow dislocation in older children and adolescents resulted in improved radiologic outcome and good elbow function in spite of diverse radiologic deformities.

Abstract
Displaced medial epicondyle fractures are common injuries encountered in pediatric orthopaedic practice. Many practitioners have successful personal experience treating these fractures through nonoperative and operative techniques. This article discusses evidence-based medicine principles related to medial epicondyle fractures. There is a dearth of high-level evidence, and yet we are constantly faced with the need for clinical decision making in the face of uncertainty. Although highly susceptible to bias, pertinent background information (current pediatric fracture textbooks) and meta-analysis of clinical research with a particular focus on harm (and number needed to harm) support surgical recommendations for most patients.

Alternative technique for open reduction and fixation of displaced pediatric medial epicondyle fractures. J Child Orthop 2012; 6:105-9. [PMID: 23730340 PMCID: PMC3364344 DOI: 10.1007/s11832-012-0395-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2011] [Accepted: 03/06/2012] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To describe an alternative positioning technique for the fixation of pediatric medial epicondyle fractures which offers some significant advantages over traditional supine positioning. METHODS At our institution, 27 patients with a displaced medial epicondyle fracture requiring open reduction and fixation were positioned prone for the procedure. The internally rotated operative arm lies on the hand table with the elbow in a natural flexed, pronated position. The elbow can be brought into extension and flexion for appropriate intraoperative radiographs. The fracture is then reduced with the arm in flexion and pronation, without having to pull excessively on the fragment. After reduction, the fragment is held easily in place for surgical fixation. A similar group of patients from the same time period positioned supine was also examined and compared to the patients who had the surgery prone. RESULTS The average age of the 27 patients was 11.2 years (range 5.1-16.9 years). Indications for operative treatment were displaced medial epicondyle fracture (14), medial epicondyle fracture with associated elbow dislocation (12), and medial epicondyle fracture with ulnar nerve symptoms (1). At a mean of 4.5 months of follow up (1-11 months), 7 patients required the removal of hardware for screw irritation. There were no infections in the 27 surgeries and there were no other intraoperative or postoperative complications. Mild loss of flexion and extension was common in the group. Patients who had surgery in the supine position were similar with regards to patient demographics and postoperative complications, including the need for screw removal. CONCLUSIONS While displaced medial epicondyle fractures can be treated successfully with traditional positioning, placing patients prone for the fixation of pediatric medial epicondyle fractures offers some significant advantages over supine positioning.

Symptomatic medial epicondyle nonunion: treatment by open reduction and fixation with a tension band construct. J Shoulder Elbow Surg 2011; 20:455-60. [PMID: 21397795 DOI: 10.1016/j.jse.2010.12.017] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2010] [Revised: 12/10/2010] [Accepted: 12/12/2010] [Indexed: 02/01/2023]
Abstract
HYPOTHESIS Nonunion of the medial epicondyle can cause symptoms of pain and instability in certain high-demand individuals. Problems with open reduction and internal fixation (ORIF) have led some to recommend excision of the nonunited fragment, followed by soft tissue repair. This study tests the hypothesis that patients with symptomatic nonunion of the medial epicondyle can be successfully treated with ORIF using a tension band construct. METHODS Five male patients were identified who underwent ORIF of a chronic, nonunited medial epicondyle fracture. Patients were a mean age of 15.8 years at presentation. The time since the original injury averaged 24 months. RESULTS At an average follow-up of 31 months, all patients reported satisfaction with their surgery. All nonunions healed, and the average postoperative extension improved significantly compared with preoperative values (P < .05). Disabilities of Arm, Shoulder and Hand scores were low (mean, 0.8) and Mayo Elbow Performance scores were high (mean, 100) at follow-up. No patient complained of prominent hardware or ulnar nerve irritation. All patients were able to return to high levels of physical activity, including one who qualified for the US Marine Corps. DISCUSSION Nonunion of the medial epicondyle can be symptomatic in certain high loading individuals. Surgical repair of the united fragment is difficult due to anatomical and biomechanical factors. CONCLUSION We believe that ORIF of chronic medial epicondyle nonunions using a tension band construct is a viable option in the symptomatic, high-demand patient.

Abstract
Traumatic dislocation of the elbow is rare in children with an incidence of 3-6% of all elbow injuries. In the literature the outcome after elbow dislocation in childhood is rarely discussed. In the present study 33 children treated in our clinic from 2001 to 2008 with an acute traumatic dislocation of the elbow were retrospectively included. All events were unilateral whereby 1 child (3%) showed a recurrence of elbow dislocation after 9 weeks, 30% had a pure dislocation, 70% had a concomitant fracture, 55% showed a fracture of the medial epicondyle, 6% a fracture of the lateral epicondyle and 9% a further fracture. Of the fractures 83% required open reduction with osteosynthesis. After an average of 4.5 years 20 children (61%) were clinically examined. There were no instabilities of the joint and only minor clinical limitations of the range of motion. The established Mayo elbow performance score showed good to excellent results for all children. Despite severe joint trauma with frequently accompanying fractures, post-traumatic functional deficits are rarely limiting, independent of the accompanying fracture. The frequency of recurrence is low and instabilities were not seen.

Abstract
PURPOSE There is ongoing debate about the management of medial epicondyle fractures in the pediatric population. This systematic review evaluated non-operative versus operative treatment of medial epicondyle fractures in pediatric and adolescent patients over the last six decades. METHODS A systematic review of the available literature was performed. Frequency-weighted mean union times were used to compare union rates for closed versus open treatments. Moreover, functional outcomes and range-of-motion variables were correlated with varying treatment modalities. Any complications, including ulnar nerve symptoms, pain, instability, infection, and residual deformity, were cataloged. RESULTS Fourteen studies, encompassing 498 patients, met the inclusion/exclusion criteria. There were 261 males and 132 female patients; the frequency-weighted average age was 11.93 years. The follow-up range was 6-216 months. Under the cumulative random effects model, the odds of union with operative fixation was 9.33 times the odds of union with non-operative treatment (P < 0.0001). There was no significant difference between operative and non-operative treatments in terms of pain at final follow-up (P = 0.73) or ulnar nerve symptoms (P = 0.412). CONCLUSIONS Operative treatment affords a significantly higher union rate over the non-operative management of medial epicondyle fractures. There was no difference in pain at final follow-up between operative and non-operative treatments. As surgical indications evolve, and the functional demands of pediatric patients increase, surgical fixation should be strongly considered to achieve stable fixation and bony union.

Abstract
In the pediatric population, medial humeral epicondylar fractures account for nearly 12% of all elbow fractures. There is ongoing debate about the surgical management of medial epicondyle fracture cases. Our technique in the operative management of medial epicondyle fractures uses the external application of an Esmarch bandage, as well as provisional fixation with needle rather than K-wire fixation. This technique decreases the need for soft-tissue release and, therefore, theoretically, maintains soft-tissue vascularity of the small fracture fragments. Moreover, it preserves the soft-tissue tension medially. It involves the use of a bandage that is universally available in orthopedic operating rooms, including those in developing nations. It is easy to apply by either the principal or assisting surgeon. With practice, it cuts down operative time and can help substitute for an assistant. This relatively simple operative technique makes for a more seamless operative process, improved reduction, and key preservation of soft-tissue vascularity.

Abstract
There is little data evaluating the risk factors, demographics, and prognoses for nonunions in children. Previous literature has reviewed time periods when contemporary techniques of internal fixation and management of open injuries had not been available. The purpose of this retrospective study was to evaluate a large consecutive series of pediatric nonunions treated at a level I trauma center. Between 1985 and 2000, 43 nonunions in 42 pediatric patients with a mean age of 9 years and 9 months (range, 3-14 years) were identified at our level I trauma center. Eleven of the original 43 fractures were open and 5 presented with active infection. Patients were observed until union or a minimum of 1 year with a mean follow-up of 50 months. Twenty of 43 nonunions (47%) were located around the elbow. Seventeen of 43 nonunions (39%) were diaphyseal. The operative fractures required a mean of 3.6 surgeries (range, 1-19 surgeries) to achieve bony union. All secondary attempts to achieve union were successful at last follow-up. Although nonunions in the pediatric population are rare, these data underscore the importance of careful evaluation and treatment of these fractures at risk for nonunion.

Abstract
Condylar and epicondylar fractures differ from other pediatric upper extremity fractures because of the anatomy and ossification of the distal humerus. These fractures are prone to nonunion,and initial deformities do not remodel well. Radiographic diagnosis and severity are difficult to determine, and adjunct studies, particularly arthrography and MRI, often are needed. The correlation of an intact cartilaginous hinge and subsequent fracture stability has helped identify fractures at risk for displacement and nonunion,prompting closer follow-up or more aggressive initial treatment. Although many humeral condylar fractures can be treated successfully with cast immobilization, operative treatment often is warranted. Specific treatment recommendations continue to evolve. The general trend is toward treating more fractures and nonunions with surgical fixation while using less invasive techniques.

Abstract
We identified 5 patients with valgus instability of the elbow due to nonunion of a previous fracture of the medial epicondyle. There were 4 male patients and 1 female patient with a mean age of 35 years (range, 15-54 years). The original avulsion fracture of the medial epicondyle had occurred a mean of 10.1 years previously (range, 4 months to 25 years), and all patients had had their initial fracture treated nonoperatively. After the development of medial epicondyle nonunion, 3 patients had been treated nonoperatively and 2 had undergone unsuccessful attempts at osteosynthesis. All patients were treated with excision of the medial epicondyle, advancement of the medial collateral ligament, and fixation to the distal humerus with suture anchors. The mean Mayo Elbow Performance Score improved from 66 preoperatively to 91 postoperatively (P <.05), and all patients were satisfied with the increased stability provided by the procedure. On the basis of our experience with these 5 patients, it appears that excision of the nonunion fragment and repair of the medial collateral ligament to the distal humerus can provide satisfactory outcomes in these patients.

Abstract
BACKGROUND The treatment of isolated, displaced fractures of the medial humeral epicondyle in children is controversial. Both plaster cast immobilization without reduction and open reduction and internal fixation have been advocated. The purpose of this long-term retrospective study was to analyze the functional and radiographic results of both nonsurgical and surgical management of these injuries. METHODS Forty-two patients who had had an isolated fracture of the medial humeral epicondyle with displacement of >5 mm at an average age of twelve years (range, eight to fifteen years) were evaluated at an average age of forty-five years (range, thirty to sixty-one years). The patients were divided into three groups that were comparable with regard to the amount of fracture displacement, age at the time of the fracture, age at the time of follow-up, sports activities and occupation, and duration of follow-up. In Group I (nineteen patients), the fracture had been treated with a long-arm plaster cast without reduction of the displaced medial epicondyle. In Group II (seventeen patients), open reduction and internal fixation with either Kirschner wires or a T-nail had been performed. In Group III (six patients), the epicondylar fragment had been excised with suture reattachment of the tendons and the medial collateral ligament. RESULTS According to a functional grading scale, there were sixteen good and three fair results in Group I. All but two patients were seen to have nonunion of the fragment on follow-up radiographs, but all had a normal result on valgus stress-testing of the elbow. The range of motion of the elbow was either normal or minimally decreased, and the grip strength of the ipsilateral hand was normal. There were fifteen good and two fair results in Group II. All patients had union of the medial epicondyle, with various radiographic deformities of the medial epicondyle, but the functional results were similar to those of the Group-I patients. The Group-III patients had four poor and two fair results. Four had constant pain at the elbow and paresthesias in the distribution of the ulnar nerve. One patient had a restricted range of motion of the elbow, four patients had an unstable elbow, and three patients had decreased grip strength of the ipsilateral hand. CONCLUSIONS In our study, nonsurgical treatment of isolated fractures of the medial humeral epicondyle with between 5 and 15 mm of displacement yielded good long-term results similar to those obtained with open reduction and internal fixation. The nonunion of the epicondylar fragment that was present in most patients who had been treated only with a cast did not adversely affect the functional results. Surgical excision of the medial epicondylar fragment should be avoided because the long-term results are poor.

Abstract
Nonunions about the elbow present a great challenge to the orthopaedic surgeon. Recent advances have enabled the surgeon to achieve much improved results. The current study outlines the treatment of nonunions of the distal humerus, proximal ulna (including olecranon, Monteggia, and coronoid nonunions), and radial head and neck nonunions. The historic problems of treating these nonunions included the use of inadequate fixation, the poor understanding of the role of soft tissue surgery in the treatment of the stiff elbow, and the failure of previous postoperative rehabilitation protocols. Advances made in the techniques of soft tissue treatment, modern methods of stable internal fixation, and early postoperative rehabilitation all have made an exceptional difference in the surgeon's ability to treat these most complex problems. The current study will provide the reader with a greater understanding of nonunions about the elbow, clinical and technical details for their treatment, and the expected results after treatment.

Abstract
Eight adolescent athletes (average age, 11 years; range, 9 to 15) underwent open reduction and internal fixation of acute, displaced medial epicondyle fractures. Fixation was achieved with a screw and washer. Four patients (50%) had associated elbow dislocations. Elbow motion in a brace was initiated 4 days after surgery. The brace allowed full flexion and extension but protected the elbow against valgus stress. Bracing was continued for 4 weeks. The average duration of followup was 10 months (range, 6 to 13). All fractures united, and full motion was achieved in seven patients. One patient lost 5 degrees of hyperextension compared with the opposite elbow. All eight elbows were stable to valgus stress and were pain-free. All patients returned to full sports activity.
