title: A minimally invasive approach for cubital tunnel release and ulnar nerve transposition.
abstract: The aim of the study is to introduce a new minimally invasive technique for ulnar nerve release and transposition.
  
  
  
  From January 2010 to May 2011, 51 patients with cubital tunnel syndrome were treated through a 1.5 to 2 cm incision. Limb functional recovery, scar esthetics, sensitivity of scar, numbness of the operating area, and patient satisfaction were assessed.
  
  
  
  No wound hematoma nor infection was observed in the group. The time of operation was 36 ± 17.2 minutes. At the final follow-up of 63 ± 7.3 months, 2-point discrimination of the small finger was improved from 6.3 ± 2.2 mm to 5.2 ± 2.4 mm. Grip and pinch strength of the hand were improved from 14.2 ± 7.7 kg and 3.7 ± 2.4 kg to 35.2 ± 12.7 kg and 4.1 ± 2.8 kg, respectively. The motor nerve conduction velocity was improved from 36.5 ± 11.2 to 44.6 ± 6.7 (m/sec). The Disabilities of the Shoulder, Arm, and Hand questionnaire score was improved from 37.2 ± 23.8 to 10.5 ± 9.6. No patients reported scar pain, sensitivity of scar, or numbness of the operating area. No revision surgery was needed. Michigan Hand Outcome score for aesthetics was 94.6%±5.1 and satisfaction was 92 ± 8, respectively. We obtained 33 excellent, 12 good, 5 fair, and 1 poor result.
  
  
  
  Ulnar nerve decompression with anterior transposition can be safely and effectively accomplished through the small incision. It can be an alternative technique producing good appearance.
