Free tissue transfer in patients with systemic lupus erythematosus.

Systemic lupus erythematosus is a non-organ specific, autoimmune disease characterised by antinuclear antibodies and vasculitis. This may manifest itself with areas of cutaneous necrosis which may require extensive excision and reconstruction. Major areas of skin and soft tissue loss may require coverage with either local or microvascular free tissue transfer. This presents potential difficulties in patients with generalised vasculitis. We present the case of a professional cellist with extensive soft tissue loss in her dominant hand, successfully reconstructed with a free latissimus dorsi muscle flap, treated with peri- and postoperative anticoagulation and corticosteroids.

Digital anaesthesia through the flexor tendon sheath at the palmar level.

Sixty five patients with various traumatic lesions of the fingers have been operated on under digital anaesthesia using 3 ml of 2% Mepivacaine injected into the flexor tendon sheath. The anaesthesia was adequate for surgery in all instances except in one patient. No complications were encountered with this technique. The authors studied the mechanism of action by dissecting a cadaveric hand after injecting a tracer (Methylene blue) in place of the local anaesthesia, suggesting, but not proving, that anaesthesia is achieved by blocking the nerve in the area of the injection.
