ABSTRACT
Statistical methods were used to calculate the possible observer error in measuring cup migration in bipolar hip arthroplasty from follow-up radiographs. Finding the "tolerance limits" by such methods helped in assigning the true significance of any observed change.

Lesions produced by splinters of wood in the soft tissues and bones of the limbs are not uncommon and may be difficult to diagnose. A detailed history and a high index of suspicion are the key to making the correct diagnosis. Investigations are usually inconclusive. Complete excision results in prompt resolution.

Twenty-six cases of fractures of the proximal end of the femur were studied to assess the role of osteomalacia. Biochemical, radiological and histological investigations were carried out in all the cases. Osteomalacia, commonly subclinical, was found to be the underlying cause in 65 per cent of cases. Histological analysis of iliac crest biopsy was the only reliable way of diagnosing subclinical osteomalacia.
