Our clinical experience with the tensor fasciae latae myocutaneous flap.

The tensor fasciae latae musculocutaneous flap is confirmed to be an easily designed and reliable flap. It is especially useful in the closure of trochanteric pressure sores, and has potential value in the repair of defects in the groin and lower abdomen. The gracilis flap is possibly more useful for closure of recurrent or large ischial sores, but the limits and dimensions of both flaps require further investigation. Closure of the donor area in the thigh may be difficult especially where excessive tissue calcification is present. Modification of the design of the flap may help to reduce the defect before closure. The rapidity of healing associated with the excellent blood supply to the T.E.L. flap renders it very safe and makes nursing care post-operatively relatively trouble-free.

Carcinoma associated with myelomeningocele.

A case is described of an epidermal carcinoma developing at the site of a myelomeningocele in a 50-year-old man. As in the three other cases of this condition which have been reported, the patient died, which reinforces the suggestion that possible malignant changes, though rare, should be taken into account when considering closure of such dysraphic lesions during childhood.

The place of the cross-leg flap in reconstructive surgery of the lower leg and foot: a review of 165 cases.

In a series of 165 cross-leg flaps, 94 per cent were successful. Some degree of necrosis occurred in almost half of them. Major necrosis requiring split-skin grafting occurred in less than one-fifth. Thrombo-embolic complications were rare and mainly in the older age group. The retunr of sensation was good; better in the flap than in the donor site. The long-term results were good with a low complication rate. On weight-bearing surfaces the cross-leg flap skin stands up well to wear and tear.

Simpson-Edinburgh low-pressure air bed: an early clinical evaluation.

A simple, inexpensive low-pressure air bed has been developed for use in situations where decubitus ulcers may arise. This bed is currently being evaluated in patients with spinal injuries, both in the hospital situation and in the home. Early experience is highly encouraging as regular turning of the patient can be safely omitted. We feel that widespread use of this bed could greatly decrease the incidence of pressure sores.
