Ninety cases of fracture of the neck of the femur were seen in patients below 17 years of age out of total 763 patients of femoral neck fractures. A variety of methods of treatment e.g. close reduction and plaster, McMurray’s Osteotomy, Smith-Petersen’s Nailing were used in different cases. A vascular necrosis was the commonest complication (40 percent). Revascularization was seen in 75 percent of these cases. A vascular necrosis was found exclusively in patients suffering severe trauma and having type IV displacement of fragments. Second commonest complication was coax vara (36.6 percent). No case of pre-mature epiphyseal fusion was noted in this series. The overall results were graded as good in 69 cases, fair in 21 and poor in none of the cases.

A review of results of internal fixation of 11 cases of acute femoral neck fracture using multiple pins, with an average follow up of 36 months is presented. There was no instance of avascular necrosis. One case had non-union which healed after cancellous bone grafting. In all the cases fixation was adequate to hold the reduction till the union was achieved.

One hundred and twenty-three patients of intracapsular fracture of neck of femur were treated by intertrochanteric displacement osteotomy with or without internal fixation. Sixty-nine patients were adequately followed. Results were considered good in 256, satisfactory in 30, and poor in 14 patients. Average shortening was 2.5 cm. Union at fracture site was observed in 70 percent of the cases immobilized by plaster of Paris spica, and in 23 percent of cases treated by internal fixation.

Twenty-five specimens of intact upper end of femora obtained soon after death were subjected to varying degrees of rotational stress under different frequencies. Fatigue fractures could be produced in dead bones at all ages irrespective of the sex. The specimens from older people required lesser magnitude of stress to produce fatigue fracture.

Forty-three children with pyogenic arthritis were analysed. The morbidity following septic arthritis of major joints infants and children continues to be high. The hip was commonest joint involved, followed by the knee. Over half the patients were less than 2 years old and many presented with foci of infection elsewhere in the body. The erythrocyte sedimentation rate was a more useful index to diagnosis than the total leucocyte count. Demonstration of pus by aspiration or arthrotomy was the most specific diagnostic test. Staphylococcus aureus was the commonest offending organism. Children presenting late following treatment elsewhere had a higher percentage of negative culture. Children presenting early had a satisfactory result with good restoration of joint function. Those presenting later than one week showed radiological changes and had a larger percentage of poor results. Early diagnosis, emergency arthrotomy followed by the appropriate antibiotics, and immobilization increase the chance of obtaining a satisfactory result.

The technique of ‘manual impaction’ is described. The analysis of 60 compound fractures in 59 patients with a follow up of 2 to 5 years, revealed that the overall results of this procedure are better than those of ‘conservative method’ and ‘internal fixation’, and are comparable to those of ‘external fixation’ method. This procedure is simple and effective in the management of open fractures of tibia.

An analytical study of 25 open fractures treated by primary internal fixation in Indian population is presented. It was observed that soft tissue healing was rapid after internal fixation of fractures. Fractures could unite in the presence of infection and infection could be controlled after removal of implant or sequestrum. Internal fixation is a good procedure in selected open fractures with extensive soft tissue injuries, where results of conservative treatment are anticipated to be poor.

Treatment of open, infected fracture has been studied clinically, radiologically and histologically in rabbit tibiae with an experimental model similar to that in human beings. Out of 24 cases where study was completed, 8 belonged to group-I (fracture immobilization by intramedullary nail), 7 to group-II (fracture immobilization by plaster of Paris cast) and 9 to group-III (fracture not immobilized). In group-II animals fractures united in 71.4 percent cases while in group-I 37.5 percent united and 25 percent showed advanced stage of union. Infection was controlled in 85.7 percent cases of group-II and 75 percent cases of group-I. Fractures of group-II showed early control of infection and quicker union, but greater number of severely infected and (comminuted) fractures in group-I might have influenced the final results.

Thirty patients of fresh fractures of the humeral shaft treated by open reduction and rigid internal fixation are presented. Patients varied in their age from 15 to 60 years, with 66.6 percent being in the range of 20-40 years. All the patients showed union and none got infected. All the patients regained full movements at the elbow and the shoulder.

Fifteen cases of Paget’s disease seen during a period of 14 years are presented. Maximum number of cases were in the sixth decade. The incidence of sarcomatous complication was 26.6 percent, however, as the series is small it has no statistical significance. It is probable that Paget’s disease is prevalent in greater number among Indians than has been thought of earlier.

Experience of 8 patients with 14 anterior tibial compartments affected is presented. Two patients had the acute and 6 the chronic form of syndromes. Fasciotomy resulted in complete relief of symptoms in chronic cases. In acute cases the fasciotomy was done late resulting in partial recovery of foot drop in one case and no recovery in the other one.

Thirty Nine cases of low backache without demonstrable organic pathology, and a control group of 31 patients with low backache due to well documented organic cause were studied with respect to distribution of psychiatric symptoms and presence of psychiatric illness, using the Indian psychiatric Interview Schedule (IPIS) and Psychiatric Examination. The psychiatric symptoms, specially pain in some other parts of the body, dizziness, nausea, pathological worrying, restlessness etc. were found more frequently in the study group than the control. Psychiatric illness was also more frequent in the study group, the common disorders found being anxiety states, hysteria and hypochondriasis. Depression was frequent equally in functional and organic backaches.

Two cases of multicentric haemangioendotheliomas have been reported. In both the cases reported here only bones of axial skeleton including skull bones were involved with exclusion of long bones of the extremities which are the usual site of involvement.
