The positional signal model for specification of the cartilaginous elements in limb development has been tested by examining the effect on the humerus of grafting a polarizing region to different positions along the anteroposterior axis of the limb bud at stage 16. The humerus between the host and grafted polarizing region was largely normal though there were variations in width, particularly t...

Introduction: Supracondylar fracture humerus is one of the commonest fractures suffered in children accounting 50 to 70% around elbow children. Complications malunion or growth deformities into cubitus varus valgus necessitates accurate reduction and union along with maintaining normal range motion. Closed splintage plasters fail achieve these goals often, so percutaneous pinning k wires from l...

Osteosarcoma occurring in the humerus is often confined to the proximal part, in which case, reconstruction after excision is less daunting. When the tumour spreads down the medullary cavity distally, a total humeral replacement is often required. This is costly and beyond the means of the average patient in a developing country. An amputation is often the procedure of first resort. We report a...

The purpose of our study was to investigate which radiological parameter had the maximal detrimental effect on functional outcome following malunion of distal radius fractures. Sixty-four women over 40 years of age who had sustained low-energy wrist fractures were included in the study. The mean age of the patients was 64 years. We compared the ulnar variance, radial inclination and palmar tilt...

BACKGROUND "Chevron"-Olecranon osteotomies are commonly used for the approach to intraarticular distal humerus fractures but are often associated with procedure related complications. We studied the triceps reflecting approach (TRA) with preservation of the extensor apparatus as a safe alternative giving a sufficient exposure to the elbow joint and helping to achieve anatomical fracture reducti...

Current knowledge regarding the basic epidemiology of fractures is largely limited to a few fracture sites, notably those of the hip and distal forearm. To clarify the patterns of incidence of limb fractures in the elderly, we used data from a 5% sample of the U.S. Medicare population over age 65 years during the years 1986-1990. We identified incident fractures of the proximal humerus, other p...
