1. The importance of recognising osteochondral fractures of the femoral condyle in the adolescent knee joint is emphasised.

2. The mechanism of the formation of the fractures is discussed. Essentially, a powerful rotary and compressive force shears off cartilage and subchondral bone. The absence of lateral condylar lesions in the experimental group lends support to the theory that the patella may cause the fracture by impingement.

3. On the basis of the mechanism a clinical classification of osteochondral fractures of the femoral condyles is presented.

4. Early surgery is recommended. The arguments for removal or replacement of the fragment are discussed.

1. Nine cases of haemangiopericytoma are described and the treatment is discussed.

2. Six of the patients had a recurrence of the tumour after local excision.

3. Four patients developed metastases and died. All had been treated by surgery and cobalt 60 beam radiation.

4. Five of the patients show no further disease. Of these, two received cobalt 60 beam radiation after surgical treatment.

1. The Moe plate has been used in 256 of 270 consecutive intertrochanteric fractures of the femur. There was an operative mortality of l8·8 per cent and an overall mortality of 20·7 per cent in a group averaging 75·2 years of age.

2. The method proved satisfactory, giving secure fixation and also approximation of the fragments by the lag action of the three large screws driven into the head. There was only one case of non-union.

3. In the survivors anatomical and functional results have been satisfactory in about 70 per cent, with half of these showing full functional recovery and the other half requiring only occasional use of a stick or crutch.

4. There are a few intertrochanteric fractures of the femur too comminuted for any form of internal fixation. Traction should be used in this group.

5. A varus deformity developed in about one half of the cases. This is consistent with a good functional result.

6. The main difficulty in these aged people has been survival. The problems have been discussed with suggestions that may perhaps reduce in part a mortality that seems inherent in this injury and at this age.

1. Screw fixation of clavicle to coracoid process, with subsequent calcification and ossification along the conoid and trapezoid ligaments, creates an extra-articular fusion of the acromio-clavicular joint.

2. Though the follow-up is admittedly early, excellent results can be obtained in the young healthy adult. It is possible to return an athlete to competitive sports and a heavy labourer to full work in a surprisingly short time.

3. The operation is of doubtful value in older patients.

4. A precise operative technique is most important in producing a successful result.

5. Screw fixation introduces a new movement into the abduction mechanism of the shoulder: synchronous scapulo-clavicular rotation.

Retrosternal dislocation of the clavicle is an unusual injury. Serious complications may arise from damage to the trachea, the great vessels of the mediastinum, the oesophagus, and the thoracic duct. Operative reduction and reconstruction of the ligaments is the most reliable treatment.
