Abstract
PURPOSE Lateral humeral condyle nonunion in children is a rare condition. The treatment protocol for nonunion of lateral humeral condyle remains controversial due to the potential complication. This study reports long-term functional outcomes of the nonunion of the lateral humeral condyle fracture. In addition, we identified the prognostic factors for nonunion of the lateral humeral condyle fracture. METHODS We conducted a multicentre retrospective cohort study of nonunion of lateral humeral condyle between January 1995 and December 2022. The patient's preoperative demographic information was reviewed. Potential risk factors of poor functional outcome, such as age, duration from initial injury, and fracture displacement, were retrieved. Functional outcomes at the latest follow-up visit were evaluated using the Mayo Elbow Performance Score (MEPS). Multivariable linear regression was deployed to evaluate the association of potential risk factors with the functional outcome. RESULTS A total of 63 patients from eight medical centers were included, of which 60 were surgically treated. Patients' average age was 7.3 years old, with a mean follow-up duration of seven years. All nonunion cases were successfully treated, resulting in a normalized humeroulnar angle. The rate of AVN was 16.7%. All patients reported excellent range of motion and MEPS at the latest follow-up. Multivariable linear regression demonstrated that Fracture displacement (β = -0.88, 95% CI -1.55 to -0.22, p = 0.010) and duration from initial injury (β = -0.09, 95% CI -0.17 to -0.02, p = 0.010) were statistically significant factors influencing functional outcome of lateral humeral condyle nonunion. CONCLUSIONS Initial fracture displacement and duration from the initial injury are statistically significantly associated with elbow function in lateral humeral condyle nonunion. However, the effect size for these factors is relatively small and does not reach clinical significance. Despite this, the functional outcome is excellent in all patients, with an average follow-up duration of seven years.

Abstract
Background Traumatic dislocation of the interphalangeal of the fifth toe is an unusual foot injury. Case presentation We report the case of a 47-year-old woman who sustained a minor foot injury for more than 30 years, resulting in chronic, irreducible dislocation of the proximal interphalangeal joint of the fifth toe. The affected proximal interphalangeal joint was accessed via a dorsal incision over the unstable interphalangeal joint. It was found that the interposed interphalangeal joint capsule and attenuated lateral collateral ligament were reconstructed, and it was stabilized by temporary insertion of a Kirschner wire. The affected joint was found to be stable, well-positioned and pain-free at the 12-month post-surgical check-up. Conclusion This unusual presentation of a chronic joint dislocation responded favorably to open reduction, soft tissue reconstruction and restabilization of the affected joint. It is suggested that this approach will provide a good and functional outcome even in cases of very long-standing joint injury.

Abstract
Dysplasia epiphysealis hemimelica or Trevor's disease is a rare disorder of localised osteochondral overgrowth affecting the epiphysis of extremities. This paper reports a 12-year-old boy presenting with a large bony mass at the left ankle diagnosed as dysplasia epiphysealis hemimelica. The articular surface of the ankle joint of the patient was evaluated with preoperative and postoperative MRIs. The 2-year postoperative MRI showed early osteoarthritis of the ankle, therefore demonstrating the importance of early excision avoiding more complex resections of intra-articular lesions.

Abstract
OBJECTIVE Stable internal fixation of the humeral shaft by less invasive percutaneous plate insertion using two separate (proximal and distal) incisions, indirect reduction by closed manipulation and fixation to preserve the soft tissue and blood supply at the fracture zone. Early mobilization of the shoulder and elbow to ensure a good functional outcome. INDICATIONS Humeral shaft fractures (classified according to AO classification as: 12-A, B, C). Humeral shaft fractures extending to the proximal or distal shaft, small or deformed medullary canal or open growth plate. CONTRAINDICATIONS Humeral shaft fractures with primary radial nerve palsy. Proximal humeral shaft fractures extending to the humeral head. Distal humeral fractures extending to the elbow joint. SURGICAL TECHNIQUE Two incisions proximal and distal to the fracture zone are used. A 3-cm proximal incision lies between the lateral border of the proximal part of the biceps and the medial border of the deltoid. Distally, a 3-cm incision is made along the lateral border of the biceps. The interval between biceps and brachialis is identified. The biceps is retracted medially to expose the musculocutaneous nerve. The brachialis muscle has dual innervation, the medial half being innervated by the musculocutaneous nerve and the lateral half by the radial nerve. The brachialis is split longitudinally at its midline. The musculocutaneous nerve is retracted along with the medial half of the brachialis, while the lateral half of the brachialis serves as a cushion to protect the radial nerve. A deep subbrachial tunnel is created from the distal to the proximal incision. The selected plate is tied with a suture to a hole at the tip of the tunneling instrument for pulling the plate back along the prepared track. The plate is aligned in the correct position on the anterior surface of the humerus. Traction is applied and the fracture reduced to restore alignment by image intensifier, followed by plate fixation with at least two bicortical locking screws or three bicortical conventional screws in each fragment. RESULTS Between January 2003 and January 2006, 23 patients were operated on using the less invasive plate osteosynthesis technique. The minimum follow-up period of 12 months was completed in 20 patients. The mean healing time was 14.6 weeks, defined as three of four cortices having stable bridging callus. In one patient with delayed union, healing was observed after 28 weeks. Functional outcomes were evaluated using the Constant Score and the Hospital for Special Surgery (HSS) Score. 19 patients had good to excellent elbow function with a mean HSS Score of 93.5 points. All patients achieved satisfactory shoulder function with a mean Constant Score of 85.8 points compared to 90.6 on the healthy side. Complications observed were one paresthesia of lateral cutaneous nerve of forearm (no radial nerve injury) and one loosening of the LCP (Locking Compression Plate) screws due to technical error.

Abstract
The authors report a case of secondary femoral fracture through the sliding hip screw portal following fixation of the femoral neck fracture. The femoral neck and subtrochanteric fracture was successfully treated by superimposing a trochanteric stabilization plate (TSP) onto the regular sliding hip screw.

Abstract
The authors report two cases of an uncommon but preventable complication after fixation of intertrochanteric hip fracture, the pseudoaneurysm of the profunda femoris artery. Both cases in the present study presented as proximal thigh mass, and soft tissue sarcoma was suspicious in one case. The diagnosis was confirmed by angiographic study and the feeding vessels were successfully occluded during angiography. Proper placement of the retractors, using a shorter drill or drill guard, accurate screw length and a shorter side-plate DHS were recommended to prevent this problem.

Abstract
The purpose of this study was to evaluate the long-term results of rectus femoris transfer in cerebral palsy children with stiff-knee gait. Thirty-eight affected limbs in 24 children were evaluated preoperatively and 1 year postoperatively by gait analysis, with 26 limbs in 18 patients having final study, averaging 4.6 years postoperatively. Functional ambulatory status was evaluated based on Hoffer's criteria on ambulation. There were statistically significant improvements of 9.8 degrees in maximum swing-phase knee flexion and 7.0 degrees in total range of knee motion at 1 year, with a small loss of knee extension in stance. At final gait analysis, the improvement in the swing-phase knee flexion was maintained, but improvement in total range of knee motion was decreased. There were no significant changes in temporal parameters. Improvement in swing-phase knee flexion and foot clearance after rectus femoris transfer was associated with loss of knee extension at long-term follow-up. Hamstring lengthening in patients who develop excessive stance-phase knee flexion may be necessary.
