Sensory,Intermittent paresthesias; vibratory perception normal or decreasedMotor,Measurable weakness in pinch or grip strengthTests,Elbow flexion test or Tinel's sign is positive; finger crossing may be abnormal.Treated by simple decompression,anterior subcutaneous transposition and anterior intramuscular transposition of the ulnar nerve.

Sensory,Persistent paresthesias; vibratory perception decreased; abnormal two-point discrimination(static >6 mm, moving >4 mm)Motor,Measurable weakness in pinch and grip plus muscle atrophyTests,Positive elbow flexion test or positive Tinel's sign may be present; finger crossing usually abnormal.Treated by simple decompression,anterior subcutaneous transposition and anterior intramuscular transposition of the ulnar nerve.

decompression of the ulnar nerve

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.

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)
