Transverse versus longitudinal skin incision in first extensor tendon release for radial styloid tenosynovitis: a randomized controlled trial

Transverse vs. Longitudinal Skin Incision in Surgery for De Quervain’s Tenosynovitis

Study Overview

De Quervain’s tenosynovitis causes pain and swelling near the wrist. When non-surgical treatments fail, surgery is often needed. This study compared two surgical techniques: transverse and longitudinal skin incisions, focusing on scars, pain, and recovery.

Methodology

Seventy patients were randomly assigned to either the transverse or longitudinal incision group. We evaluated:

  • Scarring: Using the Patient and Observer Scar Assessment Scale (POSAS)
  • Pain: Measured with a numerical rating scale
  • Function: Assessed with the Patient-Rated Wrist Evaluation (PRWE) questionnaire

Assessments were done at 2, 6, and 12 weeks after surgery.

Results

Both groups showed significant improvements in function and reduced pain. Key findings include:

  • The longitudinal incision group experienced less pain at 2 and 6 weeks.
  • By 12 weeks, pain levels were similar in both groups.
  • No infections occurred, and only three patients had temporary numbness.

Conclusions

Both incision techniques led to similar recovery outcomes and pain relief. The choice of incision should depend on the surgeon’s skill, the patient’s anatomy, and the surgery’s complexity. A personalized approach is essential for the best results.
