Case ReportsPopliteal cyst accompanied by an intra-articular cartilage lesion in a child.
The case of an 11-year-old girl presenting with a symptomatic popliteal cyst is described. There was no previous knee trauma nor could any inflammation be found. ⋯ Whereas in adults popliteal cysts are generally accompanied by intra-articular lesions, the presence of a concomitant intraarticular lesion in children is an extremely rare finding. We conclude that intraarticular lesions in the presence of popliteal cysts might have been underestimated as most of the studies regarding popliteal cysts in children were undertaken before the advent of arthroscopy, ultrasound, or MRI.

Rotational acetabular osteotomy for the treatment of dysplastic hips with end-stage osteoarthrosis--a biological alternative to total hip arthroplasty?
We evaluated the results of rotational acetabular osteotomy (RAO) for the treatment of dysplastic hips with end-stage osteoarthrosis. Sixteen patients, aged 15-45 years at the time of surgery, were reviewed at a mean follow-up of 8 years (range 3-17 years). ⋯ A subsequent total hip arthroplasty, however, was done within 2 years after RAO in two other patients who had had large bone cysts in the femoral head and acetabulum. We suggest that RAO may be the procedure of choice for selected young patients, especially teenage patients, to postpone total hip arthroplasty.

We studied a rare case of old dorsal displacement fracture of the trapezoid. Favorable results were obtained with sugical reduction, despite the fracture being old.

Case ReportsWrist pain with triangular fibrocartilage thickening.
We review the case of a patient who had wrist pain with synovial proliferation due to triangular fibrocartilage (TFC) thickening, whose pain was relieved by total TFC resection. This suggested that TFC thickening should be considered in the evaluation of patients with wrist pain.

Comparative StudyEffects of essential amino acids and lactose on bony fractures and defects in rabbits: a preliminary histomorphometric study.
An experimental study was performed in order to test the possibility of improving bone repair with the administration of a drug (Calciofix, Farmaceutici Damor SpA, Naples, Italy) containing essential amino acids and lactose. Fifty rabbits were submitted to an open transversal fracture of the left fibula and to a right femoral condyle defect. They were left untreated or treated daily with the drug orally and were divided into subgroups depending on the experimental time: 15, 30, 40, 50, 60 days. ⋯ Secondly, after 15 days the defect area was significantly smaller in treated animals than in the untreated ones (P < 0.01). At 30 and 40 days, respectively, significant differences existed between the two subgroups in connective tissue and mature bone percentages (P < 0.01 and P < 0.001). Our results seem to demonstrate that the drug significantly accelerates the rate of bone formation in fractures and bone defects in rabbits.
