VASCULARISED SOFT TISSUE TRANSFERS AS A SALVAGE FOR INFECTED KNEE, ELBOW AND SHOULDER REPLACEMENTS AND FRACTURE FIXATIONS

Australian Orthopaedic Association Limited (AOA)



Abstract

Vascularised soft tissue transfer may be helpful in the salvage of severe sepsis involving avascular tissues hosting joint replacements or other metal work. Transferred tissue covers the exposed implants and delivers intravenous antibiotics. Twenty-one cases for the knee, elbow and shoulder are presented.

Gastrocnemius flaps were used for seven knee replacements and 10 knee fractures. Antegrade radial artery flaps were used for two elbow replacements. Pectoralis major or minor flaps were used for two shoulder replacements. All procedures were performed by an orthopaedic surgeon with supplementary plastics training. Synchronous bony surgery included revision arthroplasty in seven cases, conversion to fusion in one case and preservation of existing hardware in the remainder. Sepsis was eliminated in the longterm in 9 of 10 knee fracture fixation cases, 5 out of 7 knee replacements and both elbow replacements. Both shoulder replacements remained septic despite multiple repeat procedures. Complications included necrosis of two gastrocnemius flaps, one from pre-existing partial compartment syndrome and one when combined with fusion of the knee. One other knee replacement developed further sepsis three years post procedure. No limb required amputation.

These procedures are well within the remit of orthopaedic surgeons, the non reliance on plastics surgeons allowed prompt treatment combined with bony procedures. Results were good for the knee and elbow but disappointing for the shoulder—this, probably related to the natural mobility of the joint.
