An appropriate approach to orthopaedics in developing countries.

Gifts of high technology and expensive buildings can constitute a disservice to a poor country when not accompanied by funding for the maintenance and running costs, since they will divert limited resources from more essential needs. The orthopaedic surgery that should be practised in many developing countries differs greatly from that in the contemporary Western world because of a different spectrum of disease, the consequences of uncontrolled disease processes and the less satisfactory conditions in which to function. Training in the home country is therefore essential and circumvents frustration and the brain drain from these countries. Poverty in material resources is not matched by poverty of intellect or resourcefulness, and we have much to learn from developing countries. Different cultures result in the needs of patients being quite different. Orthoses and prostheses need to be based on local crafts and resources, and some of these are illustrated. The Western world can best assist by having surgeons working, teaching and learning in the Developing World, using inexpensive means to treat the many and not to pamper the few.

The periosteum: its function reassessed.

A review of experimental work relating to the function of the periosteum, beginning with that of Macewen in 1912, is of special interest to clinicians. Macewen's failure to obtain new-bone formation following the subperiosteal removal of the radius was due to a technique that obliterated the space, an occurrence that is inevitable in total excision. The periosteum without an associated hematoma in contact with bone has no evident bone-forming properties. Except in avulsion fractures, the periosteum provides mechanical connection between the two bone fragments and is the vehicle for the revascularization of the contents of the periosteal tube. Loss of this continuity is one of the causes of fibrous union in avulsion fractures. In developing countries, delayed and unsatisfactory treatment of fractures provides valuable clinical information in the role of the periosteum. Destruction of the periosteum along with the bony shaft in extensive untreated osteomyelitis results in a missing segment of a major bone.

Pemberton's acetabuloplasty for congenital dislocation or subluxation of the hip.

The results obtained in a consecutive series of thirty-seven Pemberton operations for congenital dislocation or subluxation of the hip are reported. Over the period under review, 1967 to 1973, it was the only type of acetabuloplasty employed at Winford. Unless the mandatory concentric reduction could be obtained with ease, preliminary open reduction was favoured, especially in cases of primary care. Femoral rotation osteotomy was added for marked anteversion. The programme was designed to be complete inside fourteen weeks, and was so for eighteen hips. Secondary acetabuloplasty was performed on hips with instability or dislocation persisting despite previous treatment. The operations were performed from eighteen months to thirteen years of age. One initial failure required a repeat operation which was successful, but one severely dysplastic hip remained so. The average follow-up was six years.
