1. Continued follow-up of the 113 children with acute osteomyelitis previously reported and a study of a further thirty-eight proven cases has not changed our opinion that the correct management is rest and effective antibiotics. Operation should be undertaken only if pus is detectable clinically.

2. Bacteriological evidence shows that the flora causing this disease are less sensitive to benzylpenicillin than ten years ago and that a proportion are also likely to become resistant to methicillin and cloxacillin.

3. The most effective antibiotic combination used was fusidic acid and erythromycin. This lowered the failure rate to 10·5 per cent in thirty-eight proven cases. Two of the four failures were in haemophilus infections. No staphylococcal infection of a long bone became chronic, and all lesions were healed within three months of onset.

4. The duration of treatment (twenty-one days) and the method of splintage (removable plaster slabs) remained the same as in the previous series.

5. Careful watch must be kept on the incidence of haemophilus infections. If it rises, increasing the erythromycin or adding ampicillin may be necessary.

6. Use of the newer aqueous suspension of fusidic acid may lower the incidence of troublesome vomiting (12 per cent in this series).

7. Only 7 per cent of staphylococcus aureus infections in this hospital, and 17 per cent of such infections in our thirty-eight cases were sensitive to benzylpenicillin. It is thought that this drug has outlived its usefulness in osteomyelitis.

8. It is recommended that, on diagnosis, fusidic acid aqueous suspension 5 millilitres should be given three times a day to children aged one to five, and 10 millilitres twice a day for children aged six to twelve, with erythromycin stearate 30 milligrams per kilogram of body weight each day in divided doses.

1. Congenital coxa vara and infantile coxa vara must be separated as distinct entities.

2. Infantile coxa vara is likely to be due to distal movement of the head fragment relative to the shaft and neck. This can result either from severe trauma in normal bone or from shearing stress on an abnormal femoral neck.

3. There is no justification for considering infantile coxa vara as congenital, developmental or due to interruption of ossification. The nature of the pathological lesion at the epiphysial line in some children is unknown.

1. The results of treatment of 186 club feet have been reviewed.

2. Early strong repeated manipulation and splintage produced correction in all, but only sixty-five out of 186 remained acceptable at three years. The other 121 relapsed.

3. Relapse occurred in the first year in eight, between twelve and eighteen months in twenty-five, between eighteen and twenty-four months in twenty-three, and between twenty-four and thirty-six months in sixty-five.

4. Relapse was slightly commoner when treatment began after the first month of life.

5. Relapse was treated either by manipulation and plaster or by soft-tissue correction, leaving fifty-two out of 121 acceptable at three years and sixty-nine which were not acceptable (this includes those in plaster after soft-tissue correction, necessitated by relapse around the ages of two and a half and three and is thus adversely loaded).

6. The three year results in 186 feet were studied: 63 per cent were acceptable and 37 per cent were not. Five year results in eighty-seven feet were studied: 87·4 per cent were acceptable and 12·6 per cent were not.

7. Soft-tissue correction is described. It produced 89 per cent acceptable feet but 11 per cent relapses in 280 operations.

We describe two siblings with congenital growth defects of the distal limb bones and their progress over four years. They bear some resemblances to a boy described in 1958 by Solonen and Sulamaa and to a father and his three sons described in 1944 by Nievergelt.

Six children who complained of pain and stiffness in the back had been treated with lumbar punctures between six and ten years before they came under observation. They were found to have intrathecal epidermoid tumours in the lumbar region which are presumed to have arisen from implanted skin fragments. The main evidence for this assumption is that since 1956 sixteen patients with lumbar epidermoid tumours in patients who had had previous lumbar punctures have been reported, in contrast to the five patients with lumbar epidermoid tumours recorded before that date. This suggests that there is an additional etiological factor.

We adduce the following conclusions from our experience of using this spring-loaded compression screw on completely displaced medial fractures of the femoral neck:

1. That this method probably eliminates non-union when the head is fully viable.

2. That primary "first-intention" osseous union occurs in approximately 33·3 per cent of cases.

3. That a vascular complication, of varying severity, undetectable by orthodox radiological tests, is revealed by extrusion of the screw in 66·6 per cent of cases.

4. That these observations disprove the idea that the main obstacle to revascularisation of an ischaemic head is the existence of forces so inclined to the axis of the femoral neck as to cause "shear."

5. That, compared with the Smith-Petersen nail used for completely displaced fractures, continuous spring compression can materially reduce the incidence of utter mechanical failure within the first year after operation. This is the result of "mushroom" impaction which itself can resist shearing strain and so can permit function as a fibrous union.

6. That early and rapid extrusion is a sensitive indication of a vascular complication in the head. Forewarned by this, activity can be restricted, or possibly other measures adopted, to anticipate or permanently postpone serious trouble.

1. Fifty-one cases of fracture of the odontoid have been analysed. Forty were reported by other surgeons; eleven were new cases first reported by us.

2. Fracture of the odontoid in young children is an epiphysial separation. It occurs up to the age of seven years. As in epiphysial separations elsewhere, it unites readily, and remodelling occurs when reduction has been incomplete, so that normal anatomy is restored.

3. In adults forward displacement is twice as common as backward displacement.

4. Immediate paralysis is commoner if backward displacement occurs, but late neurological disorders are seen only after fractures with forward displacement.

5. Failure of bony healing is not dangerous if treatment has resulted in firm fibrous union, for there is neither excessive abnormal mobility nor progressive subluxation, either of which could injure the spinal cord or medulla. Neurological disorders developing after the fracture are the result of mobility from inadequate early treatment. It is the results of inadequate early treatment which have given this fracture a sinister reputation.

6. The fracture should be reduced by skeletal traction through a skull caliper. The reduction should be maintained for six weeks by continuous traction, and this should be followed by a period of six weeks in a plaster.

7. The increasing definition of the fracture-line seen in the radiographs of some patients indicates non-union.

1. The thesis is advanced that in the treatment of fractures of the adult tibia rigid fixation is desirable.

2. The mechanical factors are discussed and a technique is described which provides a high degree of fixation without exposing more than one surface of the bone.

3. The process of healing of such fractures is described and the results in thirty-three unselected patients are given.

1. This paper reports the investigation and the results of a line of treatment in thirty feet showing the peroneal spastic flat foot deformity. The questions that have aroused controversy are discussed, the evidence for previous opinions is examined, and some phenomena in relation to this condition are described.

2. It is suggested that previous opinions on this condition have been misleading, and have in many cases been made after incomplete investigation of too few cases.

3. Peroneal spastic flat foot can occur without a developmental tarsal anomaly.

4. The presence of a tarsal anomaly does not necessarily mean that the foot is incorrigibly stiff, and some of these feet show a full range of movement under anaesthesia.

5. There is no evidence from this series of cases to suggest that organic nervous disease or psychiatric disturbances played a significant part in the production of the deformity.

6. There is no evidence to suggest that the deformity is a manifestation of generalised rheumatoid arthritis.

7. This investigation does not reveal the cause of the deformity when the tarsal skeleton is normal, nor does it help to explain the reason for the onset of symptoms in a developmentally abnormal foot.

8. It is suggested that a tarsal anomaly makes the foot more likely, under average stress, to break down in this way, and that this deformity is also assumed by architecturally normal feet under heavy stress. In view of the frequency of minor tarsal anomalies among this series of thirty feet, it seems likely that all feet presenting the deformity of peroneal spastic flatness are to some degree structurally abnormal, although the exact site of the abnormality may escape us.
