Abstract
ObjectiveTo compare the outcome of carpal tunnel release using the limited longitudinal palmar incision technique and mini open transverse flexor crease incision technique. Materials and methodslBetween October 2017 and September 2019, we performed Carpal Tunnel release procedures on 122 consecutive patients with unilateral idiopathic CTS. Patients in Group A (64 patients) had a palmar mini open longitudinal incision at wrist. Patients in Group B (58 patients) had a small flexor crease transverse incision. In the non palmar transverse incision group, we used a blunt ended facelift scissors to cut the flexor retinaculum after placing a dural retractor between the retinaculum and median nerve. The preoperative and postoperative (2 weeks,6 weeks,3 months, 6 months and 1 year) patient statuses were evaluated with the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ) scores, VAS, grip strength and return to work days. ResultsThe BCTSQ symptom severity scale and functional status scale showed significant improvement following surgery in Group B compared to Group A at 2 weeks,6 weeks and 3 months (p < 0.05). At 6 months and 1 year follow up, both the symptom severity and functional status scale were comparable in both the groups. Grip strength, pillar pain and scar tenderness showed significant improvement in transverse flexor incision group compared to longitudinal palmar incision group at 6 weeks and 3 months and were comparable later on. ConclusionWe conclude that the mini open transverse flexor crease incision technique using the conventional instruments is simple, safe and cost-effective mode of treatment of idiopathic CTS when compared to the limited palmar incision technique. Though the long term outcomes are comparable in both groups, the flexor crease transverse incision group patients had better pain relief, better cosmesis and shorter recovery period than the palmar incision group
