  • Objectives
    We evaluated the effects of carpal tunnel release with a mini-open incision by analyzing symptom improvement.
  • Methods
    We retrospectively reviewed 64 carpal tunnel syndrome patients who underwent carpal tunnel release with mini-open incisions between January 2001 and December 2010. The 22 males and 42 females had a mean age of 49 years and a mean follow-up of 12 months. We analyzed postoperative symptoms using The Michigan Hand Outcome Questionnaire.
  • Results
    Patients reported complete resolution of their symptoms, and some patients who had presented with residual symptoms improved gradually. No complications or scar hypersensitivity were observed. MHQ(Michigan Hand outcomes Questionnaire) scores improved significantly between preoperative and postoperative 6 months and 12 months.
  • Conclusions
    Carpal tunnel release with mini-open incision provides a clinically effective, reliable and safe procedure.
  • Keywords: Carpal tunnel release; Carpal tunnel syndrome; Mini-open Incision

Preoperative Versus Postoperative MHQ Scores
Scale* Mean Preoperative score Mean Postoperative score (6 month) Mean Preoperative score (12 month)
Function 58.1 69.4 83.1
Activities of daily living 62.9 76.0 83.2
Work 54.7 71.1 78.4
Pain 79.6 45.5 29.2
Satisfaction 31.5 58.1 70.9

*All of the MHQ scales are based on a score of 0 to 100. For all of the scales except pain, the higher the scores the better the patient’s hand performance. For the pain scale, the lower the score the less pain the patient experiences.
