Giant-cell tumour of the tendon sheath, also called pigmented villonodular synovitis, is a benign tumour with a high incidence of recurrence. We have tried to identify risk factors for recurrence. Of the 48 patients included in the study, 14 received radiotherapy after surgery. Only two (4%) had a recurrence. This compares favourably with previously reported incidences of between 25% and 45%.

A prospective, randomised, controlled trial was performed to compare the outcome of treatment of unstable trochanteric fractures with either a short proximal femoral nail antirotation (PFNA) or dynamic hip screw (DHS). Eighty one patients with unstable fracture of the proximal part of the femur were randomised, at the time of admission, for fixation with either a short PFNA (n=42) or DHS (n= 39). The primary outcome measure was reoperation within the first postoperative year and mortality at the end of one year. Operative time, fluoroscopy time, blood loss, and any intra-operative complication were recorded for each patient. Clinical and radiological follow-up was undertaken for a minimum of 36 months. Any changes in the position of the implant or fixation failure were recorded. Hip range of motion, pain in the hip or thigh and return to work were used to compare the outcomes. There was no significant difference between 1 year mortality rates for the two groups. The mean operative time was significantly less in PFNA group (25 min) than in the DHS group (38 min). Patients treated with a PFNA experienced a shorter fluoroscopy time and less blood loss. Six patients in DHS group had implant failure while none experienced this in PFNA group. The PFNA group had a better functional outcome than the DHS group.

purpose. To review outcomes of 106 patients after complete excision of the giant cell tumour of the tendon sheath of the hand, with or without postoperative radiotherapy. Methods. Records of 77 women and 29 men aged 11 to 61 (mean, 31) years who underwent excision of giant cell tumours of the tendon sheath of the hand were reviewed. All patients presented with gradually progressive swelling; only 3 of them also presented with pain. The lesions were located on the dorsal aspect (n=11), the palmar aspect (n=66), both aspects (n=10), or circumferentially (n=14). No patient had multiple lesions. Five patients had bony erosion and 3 had neurovascular bundle involvement. results. The mean follow-up period was 12 (range, 4-22) years. 56 patients with well-encapsulated giant cell tumour in the palmer and/or dorsal aspects were classified as at low risk of recurrence. The remaining 50 patients were classified as at high risk of recurrence and underwent postoperative radiotherapy. None of Giant cell tumour of the tendon sheath of the hand
