Background: The ipsilateral olecranon with associated radial neck fractures does not include in the Bado classification of Monteggia fractures and equivalent lesions. The primary aims of this retrospective multicenter study were to characterize this type of injury and, noting its unique properties, evaluate the results of the treatment, determine the prognostic factors that influence the radiological and clinical outcome, and also give treatment strategies.
Methods: Between July 2011 and July 2016, forearm fracture patient charts were retrospectively reviewed from seven pediatric trauma centers. Patients diagnosed with ipsilateral olecranon with associated radial neck fractures and followed up for at least 24 months were included. Fracture characteristics, treatment, outcome, and complications were assessed. The clinical outcome of treatments was evaluated by the Mayo Elbow Performance Score (MEPS) and the Flynn criteria. Fisher's exact test and ANOVA test were used; significance was defined as P < 0.05.
Results: One hundred thirty-seven consecutive patients (54 girls and 83 boys) from 8292 forearm fractures patients, the mean age of 7.5 years (1.5 to 14.8), with fractures of the ipsilateral olecranon with associated radial neck fractures were identified. One hundred twenty-five patients had radiologic and clinical follow-up. According to a simplified classification system with "operate" and "don't operate" groups, including five subtypes proposed in this study, ipsilateral olecranon with associated radial neck fractures subtypes could be classified with significantly different characteristics and outcome in treatment and complications.
Conclusions: Fractures of the ipsilateral olecranon associated with the radial neck are not so rare as previously reported. Complications and poor outcomes were easy to encounter without knowing this type of fracture. Appropriate treatment strategies could be made according to a simple classification system based on the treatment result of follow-up.

Flexible Intramedullary Nail Placement in Pediatric Humerus Fractures.

Background: Flexible intramedullary nailing is an effective method of stabilization in pediatric patients with a humeral shaft fracture when surgery is indicated. Although these fractures are most often treated nonoperatively, operative indications include open fractures, bilateral injuries, compartment syndrome, pathologic fractures, neurovascular compromise, unacceptable alignment after attempted nonoperative treatment, and ipsilateral upper-extremity injuries. The current literature on flexible intramedullary nailing of the pediatric humeral shaft lacks concise descriptions of available entry points, which directly affect the subsequent technique, and of pertinent pediatric-specific anatomy.

Management of Clavicle Implant Failure With Olecranon Bone Graft: A Case Report.

Orthopaedic Surgery, Hospital Serdang, Selangor, MYS.
Bone grafts have been important treatment tools in reconstructive orthopaedic surgery for years for traumatic osseous defects, defects resulting from resection of bone tumours, arthrodesis, and osteotomy procedures. We used an autologous olecranon bone graft to fill the bone gap due to fracture comminution in a patient with right clavicle implant failure. A 21-year-old male initially underwent primary fixation with a clavicle locking plate for a comminuted middle-third right clavicle fracture.

Background: Elbow stiffness is 1 of the most common complications after operative fixation of distal humerus fractures; however, there is relatively limited literature assessing which factors are associated with this problem. The purpose of this study is to identify risk factors associated with dysfunctional elbow stiffness in distal humerus fractures after operative fixation.
Methods: A retrospective review of all distal humerus fractures that underwent operative fixation (AO/OTA 13A-C) at a single level 1 trauma center from November 2014 to October 2021.

Case: An 18-year-old right-handed male student presented after a road-traffic-accident; he had type-II Monteggia fracture dislocation associated with ipsilateral type-I capitellum fracture and comminuted lateral condyle avulsion fracture. He underwent open reduction and fixation of ulna with 3.5 DCP with autologous olecranon bone grafting and fixation of capitellum using Herbert screw along with lateral collateral ligament (LCL) repair using fiber wire.
