Rehabilitation of lower limb traumatic amputees: the Sandy Gall Afghanistan Appeal's experience.

Physical rehabilitation after lower limb traumatic amputation due to acts of war has not yet been investigated. It has been shown that patients suffering non-war injuries rehabilitate well. This study shows that despite the difficult circumstances and limited resources available in an area of conflict, good rehabilitation of war victims is possible. However, economic rehabilitation is worse than that seen in non-war populations. Given that this type of injury is very common in war zones worldwide, this failure of economic rehabilitation may represent a major healthcare issue.

Early failure of titanium alloy femoral components: a quantitative radiological analysis of osteolytic and granulomatous change.

Shot blasted titanium alloy femoral components with a coarse finish were withdrawn from use in 1987 following reports of early component failure. We reviewed all coarse titanium femoral stems used in primary total hip arthroplasty in our institution between 1985 and 1987 and compared them to a similar stem made of vitallium which was also used over the same period. We found that, at an average of 5.2 years following implantation, over two-thirds of titanium components were associated with endosteal lysis. In many of the cases the early lytic changes were asymptomatic with significant bone loss occurring prior to presentation. We discuss our findings in relation to revision surgery. We advocate that all those with coarse stem titanium components should be positively reviewed to detect early lytic change before extensive bone destruction occurs.

The Guildford elbow.

A new unconstrained elbow replacement is described and the results of 44 primary and 5 revision operations assessed. A high incidence of pain relief (82%) and functional improvement (73%) was achieved. However 23% of primary replacements later underwent loosening as assessed radiologically and 12% have undergone revision for pain. Minor complications not affecting the final result occurred in 28%. The causes and significance of the complications are analysed.

Cubital bursitis.

We describe two cases of bursitis at the insertion of the biceps tendon. They presented as swellings in the cubital fossa with symptoms of median nerve irritation. The aetiology was probably mechanical trauma; both patients were cured by operation.

Osteomyelitis in a general hospital. A five-year study showing an increase in subacute osteomyelitis.

We have reviewed 60 patients with primary bone infections; 21 of these (35%) had subacute osteomyelitis, a figure which supports other recent observations that this variant of bone infection is becoming more widespread. In this group open culture and biopsy were necessary in order to exclude bony malignancy, and a raised erythrocyte sedimentation rate proved a useful diagnostic aid. All the patients with acute osteomyelitis or with vertebral infection responded to primary treatment, but five of those with subacute osteomyelitis had recurrences.

The Guildford elbow joint.

The Guildford Elbow Joint prosthesis uses a non-rigid hinge articulation combined with intra-medullary stems to replace the humero-ulnar joint. The metal-on-plastic articulating surfaces are designed to allow some subluxation and accessory movements while remaining self-centering and stable under load. The intra-medullary stems are shaped to provide a good fit in the curves shafts of the ulna and humerus and should provide good fixation without the removal of large amounts of bone. The prosthesis is fixed with acrylic cement. The design follows, where possible, the normal anatomy and function of the elbow. A correct operative technique is important, but the procedure shows no particular difficulties.
