Brief Summary:
The aim of this study is to extend a previously reported 1 year follow-up on carpal tunnel release, in matched diabetic and non-diabetic patients,to compare outcomes 5 years after surgery.

Condition or disease
Carpal Tunnel Syndrome Diabetes Nerve Entrapment

Detailed Description:

The Follow-up investigation includes:

  1. Clinical examination of sensory and motor function
  2. Generic and disease specific self-administered questionnaires
  3. Nerve conduction study
  4. Vibration threshold testing

Study Type : Observational
Actual Enrollment : 66 participants
Observational Model: Case Control
Time Perspective: Prospective
Official Title: Five Years Follow-up After Carpal Tunnel Release in Diabetic and Non-diabetic Patients
Study Start Date : November 2010
Estimated Primary Completion Date : December 2011
Estimated Study Completion Date : December 2011

Diabetic patients operated for carpal tunnel syndrome
Non-diabetic patients operated for carpal tunnel syndrome

Primary Outcome Measures :
  1. Patient self-reported outcome questionnaire [ Time Frame: 5 years after carpal tunnel release ]
    Measured by 1). Boston Carpal Tunnel Questionnaire regarding carpal tunnel symptoms and disability. 2). Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) registering health-related quality of life. 3). Cold intolerance on a CISS score

Secondary Outcome Measures :
  1. Nerve conduction study and vibrotactile sense [ Time Frame: 5 years after carpal tunnels release ]

    Change in Median nerve function by measuring Distal motor latency and antidromic sensory conduction velocity over the carpal tunnel segment.

    Evaluate development of peripheral neuropathy by measure of sural nerve sensory conduction velocity, sural nerve amplitude and peroneal nerve motor conduction velocity.

    Vibrotactile sense of the hand measured at 7 difference frequences from 5 - 500 Hz.
