The prevalence of OCD of the humeral capitellum, including latent cases, was 3.4% among adolescent baseball players. Players with OCD lesions began playing baseball at earlier ages, had played for longer periods, and had experienced more elbow pain. The player's current baseball position may not be related to the existence of OCD lesions in adolescents.
A healthy 33-year-old man presented with a short history of viral infection and recent petechiae. Examination of the blood showed a profound thrombocytopenia. He was diagnosed as having cytomegalovirus infection by serological examination. A high level of platelet-associated immunoglobulins was demonstrated suggesting an immune basis for the thrombocytopenia and we, therefore, treated the patient with bolus methylprednisolone and gamma-globulin, resulting in prompt recovery. Recognition for CMV-induced thrombocytopenia is important for early diagnosis.
Slipped capital femoral epiphysis (SCFE) is a common disease of adolescent and the epiphysis is positioned more posteromedially in relation to the femoral neck shaft with varus SCFE; however, posterolateral displacement of the capital epiphysis, valgus SCFE, occurs less frequently. We report a case of valgus SCFE in a 17-year-old boy with hypopituitarism. After falling down, he experienced difficulty in walking. The radiographs were inconclusive; however three-dimensional computed tomography images showed lateral displacement of the epiphysis on the right femoral head. Valgus SCFE was diagnosed. The patient underwent in situ pinning of both sides. In situ pinning on the left side was performed as a prophylactic pinning because of endocrine abnormalities. At the 1-year follow-up, he could walk without any difficulty and there were no signs of pain. The epiphysis is commonly positioned more posteromedially in relation to the femoral neck shaft with most SCFE, but, in this case, the epiphysis slipped laterally. Differential diagnosis included femoral neck fracture (Delbet-Colonna type 1); however, this was less likely due to the absence of other clinical signs. Therefore, we diagnosed the patient as SCFE. When children complain of leg pain and limp, valgus SCFE that may not be visualized on anteroposterior radiographs needs to be considered.

Aim
To describe the novel hybrid fixation technique for paediatric femoral supracondylar fracture during circular external fixation of the lower limb.
Background
The Ilizarov external fixator is commonly used for various orthopaedic conditions. Difficulties associated with external fixation have previously been described. A fall while using a circular external fixator can cause ipsilateral fracture. Such fractures are ideally treated conservatively, but it is difficult to fix the frame itself. No study has reported the treatment of paediatric femoral supracondylar fracture during circular external fixation. Herein, we describe a novel hybrid fixation technique that was successfully used to treat paediatric femoral supracondylar fracture in three paediatric patients with circular external fixators.
Technique
The fracture was manually manipulated and reduced by slight hyperextension of the lower extremity under general anaesthesia. After confirmation of good reduction, a stockinette, a cast padding, and a thin core cast were applied to the ipsilateral thigh. The hinge parts were attached to the medial and lateral sides of the proximal ring. The rods were connected to the medial and lateral hinges, and the half ring was connected to the ventral side of the proximal end. Under fluoroscopic confirmation, the thin core cast of the thigh and rods were connected by cast rolled in a figure-of-eight manner. The hinges were locked with the knee joint slightly flexed.
Conclusion
The minimally invasive hybrid fixation technique enables conservative treatment of paediatric femoral supracondylar fracture during circular external fixation of the lower limb with no complications, and early exercise and recovery.
Clinical significance
This novel hybrid fixation technique will be an effective method for paediatric femoral supracondylar fracture in patients with a circular external fixator.
