1. Because of socio-medical deficiencies, osteitis in some parts of the world still conforms to the classical pattern seen before the introduction of antibiotics.

2. One of many complications is loss of continuity from widespread destruction of tubular bone.

3. Twelve patients with this complication are described. The most satisfactory treatment, when practicable, is the transference of an adjoining normal bone into the remnants of the defective one.

4. Two neonates each with a massive defect of the femur are described. This complication of osteitis at this age has not been reported before.

5. The long-term prognosis of lower limb defects is poor when there is failure of bone growth. Nevertheless, reconstructive procedures are still worth attempting because later amputation, if necessary, can be conservative, and prosthetic difficulties may thus be eased.

1. An account is given of twenty patients who had sustained accidental division of one or more foot tendons (other than tendo calcaneus).

2. Severe deformities occur when these injuries are neglected in children.

1. A large proportion of fractures were poorly reduced in this series either because the method used was inadequate or because it was inexpertly applied. At first it was thought that immobilisation in plaster gave adequate fixation but it was impossible to be certain that the reduction was not sometimes lost in the interval between manipulation and the check radiograph taken immediately after plaster had been applied. This suggested that in some cases fixation might be lost early although late redisplacement was not seen.

2. The late subjective results in patients with unreduced fractures were good, but there was some loss of thumb mobility partly due to varus deformity of the metacarpal bone and partly due to incomplete compensation for generalised stiffness in and around the joint.

3. Since loss of movement caused little disability and joint involvement rarely produced symptoms due to osteoarthritis, it seems doubtful whether the use of complex methods of treatment is justifiable.

4. Women seem to be predisposed to painful symptoms at the carpo-metacarpal joint of the thumb whether they occur after fracture or in association with non-traumatic osteoarthritis of the joint.
