ABSTRACT
The minimum distance between two stimulus points on the skin, which are perceived as distinct points, is defined as two point discrimination [TPD]. Among the two types of TPD, i.e., static and dynamic, static two-point discrimination [STPD] is commonly used to determine digital nerve integrity. Local flaps usually do well in maintaining sensibility of the covered area in terms of two-point discrimination in contrast to split thickness skin grafts [STSG]. Aim was to determine the frequency of sensory deficit in terms of Two Point Discrimination [TPD] in Split Thickness Skin Grafts [STSG] and local flaps for soft tissue defects of fingers three months postoperatively. Thirty-five patients underwent local flap coverage and other thirty-five had split thickness skin grafting for soft tissue defects of fingers depending upon nature of defect. Patients were followed up at 2, 4, 8 and 12 weeks. TPD, measured at 3 months of follow-up, of 7 mm was considered normal [no sensory deficit] and TPD of 8mm or more was considered as sensory deficit. The sensory deficit observed at the end of 12[th] week post operatively was 8.6% in the patients with local flap coverage [3 patients] and 45.7% with STSG [16 patients]. Patients with no sensory deficit were 91.4% [32 patients] in the local flap coverage and 54.3% [19 patients] in the STSG at 12th week of follow up. The relative ratio [RR] of sensory deficit in local flaps and STSG was 5 [>2]. Local flaps are better options in terms of TPD preservation as opposed to STSG for soft tissue defects of fingers.
