Functional disturbance of the inferior radio-ulnar joint due to hypoplasia of the lower end of the ulna.

Variations in the difference between the ulnar and radial length are described as the ulnar variance. The frequency of these variants are studied in a Greek population. It was found that the commonest is the neutral variant (51.7%) and less common the minus variant (33.6%). Five cases of an extreme bilateral minus variant is also reported. These cases were accompanied, except the hypoplasia of the ulna, by increased obliquity of the radial lower epiphysis. Functional disturbance from this abnormality was found to be minimal.

Girdlestone's operation: a follow-up study.

A study was made of 43 patients (48 hips) operated for diseases of the hip using Girdlestone's method. The follow-up time ranged from 2.5 to 13 years. For assessment of the post-operative results the following parameters were taken into consideration: pain, range of movement, gait and the patient's opinion. These were studied separately and in relation to the type of disease, the patient's age, and the time which had elapsed since the operation. Pain decreased in a considerable number of patients and range of movement and gait improved. The patients were generally in favor of the operation, and felt it had had a beneficial effect on their condition.
