Study Status: Recruiting
Recruit Status: Unknown status
Study Type: Interventional

Official Title: Comparison of Simple Decompression Versus Anterior Subcutaneous and Intramuscular Transposition of the Ulnar Nerve for Moderate and Severe Cubital Tunnel Syndrome ：

Brief Summary: The purpose of this study is to determine which is the best surgery to treat different severity scales of cubital tunnel syndrome.

Detailed Summary: The purpose of this study is to determine which one of the simple decompression,anterior subcutaneous and intramuscular transposition of the ulnar nerve has the best outcomes for moderate and severe cubital tunnel syndrome.

Current Primary Outcome: sensation [ Time Frame: at 6 months post-operatively ]

Sensory disturbance were tested with Semmes-Weinstein filaments and sensory deficits were categorized according to the Yale sensory scale. According to standard scoring system that designed, the severity of sensation and function of the ulnar nerve was scored as follows: ---- 0, Abscent sensation; 1, Decrease or abnormal sensation; 2, Intact sensation.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Muscle strength [ Time Frame: at 6 months post-operatively ]
    Muscle strength was evaluated with the grading system from the Medical Research Council which is based upon a scale of zero to five: 0, No muscle contraction; 1,Flicker or trace of muscle contraction; 2,Limb or joint movement possible only with gravity eliminated; 3,Limb or joint movement against gravity only; 4,Power decreased but limb or joint movement possible against resistance; 5,Normal power against resistance. Then results were scored as follows: ---- 0,Poor (0-1); 1,Moderate (2-3); 2,Good (4-5)
  • pain [ Time Frame: at 6 months post-operatively ]
    Visual Analogue Scale (VAS) with scores of zero to ten (0 for no pain and 10 intolerable pain) then scored as follows: ---- 0, Sever (8-10); 1, Slight (4-7); 2, none (0-3)
  • electromyography [ Time Frame: at 6 months post-operatively ]
    Compare the result at 6 months post-operatively with the result before operation.To see if there is an improvement in the function of the ulnar nerve.0,no improvement;1,improvement.


Original Secondary Outcome: Same as current
