1. Evidence is presented which suggests that after total joint replacement bone necrosis and consequent loosening of the prosthesis may be due to the development of sensitivity to the metals used.

2. Nine patients, from a total of fourteen with loose prostheses, were found to be metal sensitive by skin-patch testing. In twenty-four patients with intact prostheses no sensitivity was demonstrated.

3. In material from the joints of sensitive patients the metal content was raised.

4. Examination of this material showed necrosis of bone and soft tissue following obliterative changes in the vascular supply.

5. Similar reactions were found following the injection of cobalt into a sensitive patient.

6. The release of metal around a prosthesis is greatest where metal rubs against itself.

7. We conclude that prostheses in which metal articulates with polyethylene should be preferred; that any patient in whom loosening or fragmentation occurs should be patch tested; and that if sensitivity is found the implant should be removed.

1. In chronic osteomyelitis grafting a cavity with split skin is a reliable method of treatment. The skin cover so obtained is durable.

2. The method may be used with good prospects of success even when the cavity is large and there is extensive disease of bone.

3. Operation is indicated for the relief of pain, to close a sinus or sinuses, to obtain healing of an ulcer or to prevent recurrent episodes of acute infection.

4. The technique of operation employed in eleven cases is described and illustrative case reports are given.

An attempt has been made to describe some of the ways in which the element of rotation, which is so important a part of the function of the normal forearm, has a bearing upon the mechanism and treatment of forearm injuries. In particular, distinction is drawn between those injuries in which the shaft of the radius remains in continuity, and those in which there is a complete fracture of the bone. In the former, rotation of the hand in the reduction will be transmitted to the upper end of the radius, and extremes of rotational movement may safely be used to obtain and hold a reduction. In the latter there is likely to be a rotational deformity between the two radial fragments, and the lower radial fragment must be placed in accurate rotational alignment with the upper. In the first group reduction, and in certain cases immobilisation, in full pronation or full supination has been shown to have a place in the treatment of those cases in which a rotation violence has shaped the pattern of the injury. Soft tissues may be used to guide and hold a reduction in a rotational injury, just as in injuries of other types. An injury caused by forced pronation should logically be treated in full supination, for only thus are the intact soft tissues on the "pronation side" of the limb used to the best advantage.

In the mechanism of injuries caused by rotation violence it is emphasized that vertical compression is usually the basic force, to which a rotation force may be added by the direction of momentum of the body weight. Such injuries may be grouped into forced rotation injuries (in which the violence applied has taken the limb beyond the normal ranges of rotational movement), and injuries occurring while the limb is pronating or supinating. In the latter group the rotational element determines the pattern of the injury: pronation and flexion are closely allied, and a fracture occurring while the forearm is pronating will develop a backward angulation: so also a supination injury will produce a forward angulation.

On the basis of these considerations injuries of the forearm may be classified as follows:

Injuries in which the shaft of the radius remains in continuity

Forced proiiation injuries:

1) Forward dislocation of the head of the radius.

2) Backward dislocation of the lower end of the ulna.

3) The anterior Monteggia fracture-dislocation.

These injuries should be reduced and immobilised in full supination to prevent recurrence of deformity. The lateral and posterior Monteggia injuries are probably variants of dislocation of the elbow and are not caused by rotation violence. In general it is considered that all dislocations of the head of the radius are best treated in full supination.

Pronation injuries:

Greenstick fractures of the radius, and of both bones of the forearm, with backward angulation. Reduction of deformity is most easily obtained by manipulating into full supination. Certain fractures may with advantage be immobilised in this position.

Supination injuries:

Greenstick fractures of the forearm with forward angulation. Reduction is best obtained by full pronation.

Injuries in which the shaft of the radius is in two separate fragments

This group includes all complete fractures of the shaft of the radius and of both bones of the forearm. There is nearly always a rotational deformity between the two radial fragments and its correction is a dominant factor in the treatment.

1. A series of 110 cases of trochanteric fractures treated by internal fixation with the Capener-Neufeld nail-plate is presented. The age incidence, mortality, complications and functional results are discussed in detail.

2. The results are compared with those of two series of cases treated conservatively: a) 101 cases treated conservatively in hospital; b) 25 cases sent home by reason of shortage of hospital beds.

3. From a consideration of these three series, and from study of similar series of cases reported in the literature, it is concluded that routine operative treatment of trochanteric fractures offers the advantages of lowered mortality, improved function, economy of hospital beds, and greater comfort and mobility of the patient.

4. Certain points in the management of cases during the operation and in the convalescent period are discussed.

1 . Anterior dislocation of the head of the radius with or without fracture of the ulna is a forced pronation injury.

2. Full supination is essential for reduction, and immobilisation in full supination is the surest safeguard against recurrence of the deformity.

1. Trochanteric fractures are classified, with special emphasis on the stability or instability of the fracture. The importance of the cortical buttress of bone on the inner side of the femoral neck and shaft is stressed.

2. Three series of cases are presented: a) one hundred and one cases treated conservatively in hospital; b) twenty-five cases sent home by reason of lack of hospital beds; c) twenty-two cases treated by fixation with a Capener-Neufeld nail-plate.

3. From consideration of these three series, and from study of similar series of cases reported in the literature, it is suggested that routine operative treatment of trochanteric fractures has the advantages of greater comfort and mobility of the patient, lowered mortality, and economy of hospital beds.

4. Certain features of the operation of internal fixation by the Capener-Neufeld nail-plate are discussed. A director, for more efficient insertion of the nail-plate, is described.

5. The importance of early mobility after operation is emphasized. Only a small proportion of Patients can be allowed early weight-bearing but almost all can be got up in a chair, and most can be taught to get about with crutches, without weight-bearing on the fractured limb, within a few days of operation.
