Through-knee amputation in high-risk patients with vascular disease: indications, complications and rehabilitation.

During a 10-year period 104 patients (mean age 72 years) had 106 through-knee amputations. Indications for surgery were: limb gangrene, 67 (64 per cent); ischaemic ulceration, 22 (21 per cent); rest pain, 9; knee contractures, 6. Thirty patients had had previous unsuccessful vascular reconstructive surgery and five had had a failed femoral embolectomy. The through-knee disarticulation used lateral skin flaps. The mortality was 21 (20 per cent). Of the 83 survivors, 59 (71 per cent) underwent uncomplicated primary wound healing; 36 (43 per cent) of the survivors were unsuitable for rehabilitation on a prosthesis. The remaining 47 (57 per cent) were walking before discharge 30-130 days (mean 68 days) after amputation. Through-knee amputation is a rapid, relatively bloodless, amputation and is a useful debridement procedure. The many surgical and functional advantages, in conjunction with the recent reports of better rehabilitation compared with the above-knee or Gritti-Stokes amputation, suggests that the through-knee amputation deserves greater consideration.

Post-amputation pneumatic walking aid.

A pneumatic walking training aid is described that has been developed by the Biomechanical Research and Development Unit, Roehampton, from the original design by Little. The new design has been used in the management of 87 amputations, including 44 patients over the age of 70. Ninety-four per cent of these patients were rehabilitated to walking independently on a pylon or prosthesis.

Long posterior flap amputation in geriatric patients with ischaemic disease.

A series of 165 primary amputations performed on 148 patients at Queen Mary's Hospital, Roehampton, from 1967 to 1975 is reported. The average age of these patients was 70 years, the oldest being 95. Those aged 70 years and over are considered in special detail. The problems of management of these elderly patients are complex, involving medical, surgical, and social problems. The object of treatment is to restore these patients to their previous way of life with the shortest possible time in hospital. Every patient is assessed with a view to arterial surgery, and amputation is avoided where possible by a lumbar sympathetic block or direct arterial surgery. When amputation cannot be avoided a below-knee level is selected if possible. A long posterior flap technique is used which forms a myoplasty of the gastrocnemius muscle; thus the ischaemic anterior tibial skin is avoided. Before the operation the patient is assessed by a specialist team and the management is discussed in detail. Every patient is kept in hospital until rehabilitation is achieved to the point of independence inside the home. Of the 90 patients in the group aged 70 years and over, 22% had above-knee amputations and 75% had below-knee amputations, with the result that 69% of the latter were discharged home walking. This result is contrasted with the smaller number who had an above-knee amputation. Below-knee amputation gives the elderly patient a better chance of walking because of the use of the patellar tendon bearing prosthesis. When followed up 36% of those patients with below-knee amputation were fully independent for periods exceeding six months. The price of a below-knee level of amputation is a longer hospital stay, but the quality of function and mobility obtained by the patient makes this worth while.

Immediate operative fitting of upper limb prosthesis at the time of amputation.

Three patients are described--2 with an above-elbow amputation and 1 with a through-wrist amputation--in whom a temporary prosthesis was applied on the operating table and in all of whom function was rapidly established. The patients did not become one-handed, with the result that they have all continued to wear their prosthesis throughout their working hours and use their artificial hand for all everday functions. The value of this technique in making the patient accept the prosthesis and therefore to make full use of it suggests that this procedure should be more widely applied in patients who require upper limb amputation.
