This investigation examined the validity of the hypothesis that the acetabulum in congenital dislocation of the hip will develop satisfactorily provided accurate congruous and concentric reduction is obtained as early as possible, and is maintained throughout growth.

Seventy-two patients with eighty-five hips were studied. The children were more than one year old on admission and over ten years at the time of review. Acetabular development was assessed radiologically by measurement of the acetabular angle. Angles of less than 21 degrees were regarded as normal, and more than 21 degrees as indicating some failure of development. Satisfactory acetabular development occurred in 80 per cent (angles 24 degrees or below), and was unsatisfactory in 20 per cent (angles above 24 degrees).

If three errors in management, namely failure to obtain congruity, failure to maintain congruity and ischaemic necrosis secondary to manipulative reductions, are excluded from the analysis, it is found that 95 per cent of acetabula develop satisfactorily. The outcome is largely independent of the age on admission up to four years old, and of bilateral involvement. It is concluded that acetabuloplasty should not be necessary if the patient is admitted under the age of four or congruity is obtained in the functional position under four and a half years.

1. A primary subacute type of staphylococcal osteomyelitis has been described. It is the commonest form of osteomyelitis seen in East Africa, and the incidence appears to be increasing in Great Britain.

2. A review of the literature indicates that this is not a new disease but that in the past there has been some confusion in terminology.

3. The causative organism is a coagulase positive staphylococcus, but in a few instances a coagulase negative one has been isolated. The staphylococcus is thought to be of reduced virulence and in East Africa it is likely that the population has acquired an increased resistance to the staphylococcus.

4. Two radiologically distinct groups are recognised, depending on whether a bone abscess is present or not. In the first group there are two types of localised abscesses: the familiar Brodie's lesion and the less well recognised large bone abscess that occurs in the metaphysis of a long bone. While the pathology of the two types is similar, the radiological features are quite distinct. The lesions in the second group are characterised by extensive diaphysial changes, with or without metaphysial involvement, and an obvious abscess cannot usually be demonstrated.

5. The main clinical features are the long history, often weeks or months, before diagnosis; insignificant or absent general reaction to the infection and minimum physical signs.

6. Vertebral body osteomyelitis in adults is included because it generally presents as a subacute infection; the difficulties in distinguishing it from a tuberculous infection are outlined.

7. The most useful diagnostic aids are the staphylococcal antibody titres (especially in vertebral infections) and the erythrocyte sedimentation rate. A limited surgical exposure is usually required if the causative organism is to be isolated and empirical antibiotic therapy is to be avoided. The total and differential white blood count are so often normal in these patients that they are considered to be of no diagnostic value.

8. Curettage and local antibiotics together will cure the localised bone abscess. Other lesions may be effectively treated by systemic antibiotics alone, but in the later stages removal of sequestra and infected granulation tissue may be necessary. In this instance it is essential to make a planned incision and to cut a window in the bone large enough to expose the whole of the lesion; primary suture of the wound is advocated.

1. The clinical and radiological results of seventy-one osteotomies for primary osteoarthritis of the hip performed with internal fixation have been examined two to eight years after operation. Advanced cases where osteotomy would have been purely a salvage procedure were excluded.

2. The hips were divided into two groups: one in a relatively early and the other in a later intermediate stage of the disease. The two criteria for inclusion in the "early" group were a) fiexion movement of 90 degrees or more, either with the patient conscious or completely relaxed under anaesthesia, and b) no collapse of bone seen in the radiograph.

3. The clinical results show that early osteotomy seldom fails to give relief of pain, which is closely correlated with improved function and a favourable assessment of the operation by the patient. A good range of flexion, not less than 70 degrees and frequently 90 degrees, is retained when the criteria mentioned above obtain.

4. The radiological assessment was based upon examination of the joint space, the cystic appearances and the degree of collapse of bone, if any, as seen in serial films. There was convincing evidence of regression indicating arrest of the arthritic process in 70 per cent of the "early" cases.

5. Regression after osteotomy appears to be a well-defined process which is more commonly observed and more complete when the osteotomy is performed sooner rather than at a later stage of the disease. With few exceptions a good radiological result is associated with a good clinical result.

6. Some of the possible causes of failure are discussed. Osteotomy is more likely to fail if delayed till stiffness is severe and collapse of bone has begun. Large cysts, rapid advance of the disease, and a valgus osteotomy in the presence of lateral subluxation may also prejudice the results.

7. This review offers good support for Nissen's suggestion that in primary osteoarthritis of the hip osteotomy should be performed early, while the joint is still mobile and capable of repair, in order to retain good function.

8. Relief from pain is not the only consideration in deciding when to operate; the prospects of arresting the disease and of stimulating a healing reaction in the disordered cancellous bone and articular cartilage by early osteotomy should always be kept in mind.

9. In many respects the findings of this review are complementary to those of Postel and Vaillant (1962) who reported excellent results from varus osteotomy of Pauwels' type in a series of cases of subluxation of the hip with pain but without frank secondary osteoarthritic change.

1. Forty-five cases of acute osteomyelitis have been reviewed with the object of determining the causes of relapse. The importance of an early diagnosis and prompt treatment is stressed, and the question of when to stop antibiotic drugs is discussed.

2. The provisional diagnosis was anterior poliomyelitis in seventeen out of forty-five patients; acute osteomyelitis was diagnosed in twelve only. The criteria for making an early diagnosis are discussed, including the value and limitation of blood culture.

3. The place of operation is discussed and certain conclusions are set out.
