Venous leg ulcers after hip replacement. A clinical evaluation at 5 to 12 years.
Venous ulceration is a chronic disabling complication of deep-vein thrombosis. The aim of this study was to estimate the incidence of venous leg ulcers five years or more after total hip replacement (THR) and to investigate some of the clinical features associated with their development. We carried out a postal survey of all patients who had undergone a THR 5 to 12 years previously. ⋯ The ulcers occurred more commonly on the operated side and developed at a mean of 5.8 years (18 months to 12 years) after the first arthroplasty. A mean of 1.9 arthroplasties (1 to 5) (primary and revision) were carried out before the ulcers appeared. The overall incidence of ulcers was similar to that in the general population.

Open reduction and internal fixation of comminuted fractures of the radial head using low-profile mini-plates.
Between 1996 and 2000, we treated ten patients with severely comminuted fractures of the radial head using low-profile mini-plates. Their mean age was 42 years (24 to 71). Three fractures were Mason type III and seven were Mason-Johnston type IV. ⋯ According to the Broberg and Morrey functional elbow index, the mean score was 90.7 points (73 to 100), and the outcome was excellent in three patients, good in six and fair in one. These results compare favourably with those reported previously. The technique is applicable to severely comminuted fractures of the radial head which otherwise would require excision.

Relative anterior spinal overgrowth in adolescent idiopathic scoliosis. Results of disproportionate endochondral-membranous bone growth.
We undertook a comparative study of magnetic resonance imaging (MRI) vertebral morphometry of thoracic vertebrae of girls with adolescent idiopathic thoracic scoliosis (AIS) and age and gender-matched normal subjects, in order to investigate abnormal differential growth of the anterior and posterior elements of the thoracic vertebrae in patients with scoliosis. Previous studies have suggested that disproportionate growth of the anterior and posterior columns may contribute to the development of AIS. Whole spine MRI was undertaken on 83 girls with AIS between the age of 12 and 14 years, and Cobb's angles of between 20 degrees and 90 degrees, and 22 age-matched controls. ⋯ There was also a significant positive correlation between the scoliosis severity score and the ratio of differential growth between the anterior and posterior columns for each thoracic vertebra (p < 0.01). Compared with age-matched controls, the longitudinal growth of the vertebral bodies in patients with AIS is disproportionate and faster and mainly occurs by endochondral ossification. In contrast, the circumferential growth by membranous ossification is slower in both the vertebral bodies and pedicles.

Case ReportsIntrapelvic dislocation of the head of femur through the obturator foramen associated with ipsilateral fracture femur.
We describe a case of traumatic anterior dislocation of the hip in a 14-year-old boy with associated intrapelvic displacement of the femoral head and ipsilateral fractures of the shaft of the femur and greater trochanter. There was a delay in presentation of eight days. At operation the femoral head was reduced into the acetabulum after enlarging the obturator foramen by performing an osteotomy of the superior pubic ramus.
