We report a case of giant trichoblastoma, a rare benign hair germ tumor. A 73-year-old man presented with a soft-tissue mass on his upper arm. ⋯ The size of the tumor was 9.5 x 7 x 9.5 cm, one of the largest trichoblastomas ever reported. The rarity and gigantic size of the tumor, together with its misleading clinical features, prompted us to report our case.

ReviewPrevalence of popliteal cysts in children. A sonographic study and review of the literature.
Popliteal cysts in children differ from those in adults. They are considered to be less frequent and usually appear in the absence of intra-articular lesions. However, their prevalence in asymptomatic children is unknown. ⋯ A popliteal cyst could be identified in 4 patients. The prevalence of asymptomatic popliteal cysts was thus 2.4%. For 2 of these patients, we obtained magnetic resonance image of the knee which showed no concommitant intra-articular pathology.

Hip dislocation has long been one of the major complications after total hip arthroplasty (THA). From 1980 to 1994, we performed 2728 THAs (including primary and revision cases). There were 97 hips (3. 6%) with the complication of dislocation, 62 of which were followed up for at least 2 years (mean 5.3 years; range 2-12 years). ⋯ The success rate for the first attempt at closed reduction for the treatment of dislocation was 41%; the success rate decreased gradually with the number of attempts. For the recurrent dislocation group, bracing for 4-6 weeks with training was recommended for the postural type and bracing for 3 months with muscle training for the soft-tissue imbalance type. Only 15% of the dislocated hips needed re-operation, and most of the patients resolved the problem after being informed and undergoing muscle training.

Clinical TrialEffect of reaming bone grafting on treating femoral shaft aseptic nonunion after plating.
Rigid intramdullary nailing with cancellous bone grafting provided by intramedullary reaming was prospectively used to treat femoral shaft aseptic nonunions after plating. Indications for this technique were a femoral shaft nonunion with an inserted plate, no previous infection sign in the treatment course, less than 1.5 cm shortening, and no segmental bony defects. After the plate was removed, a flexible guidewire was inserted antegradely. ⋯ There were no significant complications. We conclude that for indicated cases, reaming bone grafting is a very effective technique and avoided donor site morbidity. Therefore, whenever possible, this technique could be considered first.
