Dermotaxis v/s loop suture technique for closure of fasciotomy wounds: a study of 50 cases

Abstract

Fasciotomy incisions lead to large, unsightly, chronic wounds after surgical intervention. Classic management was to use split-thickness skin grafts, but this leads to insensate skin with reports that as many as 23% of patients are dissatisfied by the appearance of the wound. Since no skin loss has occurred with the fasciotomy incision, utilizing the dermal properties of creep, stress relaxation and load cycling, closure can be achieved in a better way. We describe using dermotaxis for skin edge approximation that is done using inexpensive equipment available readily in any standard operating room. Twenty-five patients had fasciotomy wounds closed either by dermotaxis or a loop suture technique with the inclusion criteria being closed fractures, no concomitant skin loss, fracture-related compartment syndrome and fasciotomy performed within 36 h. The fasciotomy incision was closed in a single stage by loop suture technique or gradually by dermotaxis once the oedema had settled between 3 and 5 days. Results were graded as excellent if approximation could be achieved, good if sutures had to be applied for protective care and poor if wounds needed to be skin-grafted. In the dermotaxis group, results were excellent in 15, good in 8 and poor in 2 cases. In the loop suture technique group, results were excellent in 20, good in 4 and poor in 1 case. Dermal apposition using inexpensive, readily available equipment is an alternative method for closure of fasciotomy wounds. If limb oedema has settled sufficiently, closure using a loop suture can be done in a single stage. If the limb remains oedematous, gradual closure can be done using dermotaxis.
