Idiopathic transient osteoporosis of the hip.

We have reviewed 11 patients with idiopathic transient osteoporosis of the hip; the six who were women all developed the condition during pregnancy. Both simultaneous and sequential bilateral involvement were seen, but biochemical studies were consistently normal and one synovial biopsy showed only non-specific inflammation. Radioisotope bone scans and CT scans were useful to aid diagnosis. Treatment by limiting weight-bearing relieved symptoms, and spontaneous resolution was paralleled by radiographic remineralisation, usually within a few months. One patient developed a stress fracture of the hip and other areas of transient osteoporosis. A hip involved by the condition should be protected from overloading until bone density has recovered.

Fibular bowing due to tibial shortening in isolated fracture of the tibia: failure of late segmental fibulectomy to relieve ankle pain.

Fracture of the tibia with an intact fibula is prone to delayed and nonunion or varus malunion and, as a complication of the latter, late arthrosis of the ankle joint. A less well-known type of malunion is tibial shortening with fibular bowing due to relative fibular lengthening. We present such a case with chronic ankle pain. Late segmental fibulectomy failed to improve the symptoms. We recommend primary segmental fibulectomy in all isolated fractures of the tibial shaft in adults and adolescents, in order to forestall the early and late complications.

Traumatic ulnar variance in Kienböck's disease.

A case of unilateral ulnar minus variant, almost certainly caused by trauma to the distal ulnar growth plate, and ipsilateral Kienböck's disease is described. The contralateral wrist was normal in all respects. This constitutes additional evidence for the etiologic relationship between Kienböck's disease and the presence of the ulnar minus variant.

Crush injury to the lower limbs. Treatment of the local injury.

We treated fifteen patients who had been trapped under the masonry of collapsed buildings for various periods of time. In one group of patients who had been buried for twelve hours, treatment commenced only twenty-four hours after the injury, and the other group was treated more promptly. In the second group, the success of forced diuresis and alkalinization of the urine in preventing the renal complications of the crush syndrome was evident. A reassessment of the treatment of the local lesion was made and a scheme of treatment is proposed. The injury is essentially closed, and incomplete excision of the necrotic muscle is fraught with risk. Local rigor in the affected muscles is important.

Fracture of the transverse process of the fifth lumbar vertebra.

Fracture of the transverse process of the fifth lumbar vertebra is caused by traction through the iliolumbar ligament by the vertically and proximally or medially dislocated hemipelvis. This fracture is therefore associated with the vertical shearing force of Malgaigne's fracture-dislocation of the pelvis or the lateral crush fracture-dislocation of the pelvis. In the absence of evidence on a radiograph of a fracture through the sacroiliac area or dislocation or subluxation of the sacroiliac joint, the fracture of the transverse process of the fifth lumbar vertebra may be the only radiological evidence for posterior instability of the ipsilateral hemipelvis.

Can inguinal hernia be caused by a fractured spine?

Three patients who had suffered fractures of the body of the first lumbar vertebra reported the appearance of inguinal herniae shortly after resuming walking. It is postulated that a neurapraxia or axonotmesis of the first lumbar nerve root may weaken the conjoint tendon.

Magnetic resonance imaging in orthopaedic surgery. A glimpse into the future.

Magnetic resonance images (MRI) were obtained of 10 healthy volunteers and 70 patients suffering from various orthopaedic disorders. Selected images of soft tissue, joint, bone and spinal abnormalities are presented and their interpretation is described. Although we have been using MRI for only a very short time, it is already possible to see its advantages: it provides good images of soft-tissues, detailed pictures of bone marrow, and excellent visualisation of the spine and spinal cord. The decision-making process in surgical procedures will in the future be influenced by this technique.

External fixation in wartime limb surgery.

During the Lebanon War, 1982, limb stability was achieved by the use of external fixation in 45 severe limb injuries. The indications, advantages, techniques and results are reviewed. At follow-up after 1 year there were no cases of chronic bone infection. Two limbs had to be amputated for vascular insufficiency. The skillful, judicious use of external fixation in the treatment of war injuries is an important technical advance in the treatment of severe limb injuries.

The gastrocnemius muscle flap in the correction of severe flexion contracture of the knee.

Extreme flexion contracture of the knees due to extra-articular contracture of the knee joints is a frequent deformity in catastrophic neurological lesions such as multiple sclerosis, meningomyelocoele, paraplegia, quadriplegia, and cerebral spastic paralysis. Such gross knee contractures together with the coexisting hip flexion contractures create a severe nursing problem. Adequate perineal hygiene and positioning are very difficult to achieve and thus pressure sores frequently develop in these bed-ridden patients in spite of devoted nursing care. The orthopaedic surgeon can help alleviate the plight of these unfortunate victims: first the hip joint contractures are released by the classical methods and then, at the same session, the knee contractures: a simple one stage procedure is described. Primary cover of the large popliteal skin defect is achieved by a gastrocnemius versatile muscle flap, which is itself covered by a free split skin graft. An illustrative case is described.
