Primary Outcome Measures:
  • Pain [ Time Frame: at 6 months post-operatively ] [ Designated as safety issue: Yes ]
    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)

Secondary Outcome Measures:
  • sensation [ Time Frame: at 6 months post-operatively ] [ Designated as safety issue: Yes ]
    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 [ Time Frame: at 6 months post-operatively ] [ Designated as safety issue: Yes ]
    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)

  • Muscle atrophy [ Time Frame: at 6 months post-operatively ] [ Designated as safety issue: Yes ]
    Muscle atrophy was scored with one orthopedic surgeon as follows: 0, sever; 1, moderate; 2, none

Arms Assigned Interventions
anterior submuscular transposition
it is kind of surgical method
Procedure: Anterior submuscular transposition
transposition of ulnar nerve into muscular tissue
Other Name: ASMT
Anterior subcutaneous transposition
it is kind of surgical method
Procedure: anterior subcutaneous transposition
transposition of ulnar nerve into subcutaneous bed
Other Name: ASCT

Detailed Description:
Compression of the ulnar nerve at the cubital tunnel is the most common cause of numbness on the ulnar side of the hand. We aimed to compare patient outcomes included pain, sensation, muscle strength and muscle atrophy in two methods of surgery contain Anterior Sub Cutaneous Transposition (ASCT) and Anterior Sub Muscular Transposition (ASMT) of the ulnar nerve in Cubital tunnel syndrome.

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • patients with confirmed cubital tunnel syndrome

Exclusion Criteria:

  • Significant cervical spine and shoulder disease
  • deformity or distortion of the cubital tunnel due to previous trauma to elbow
  • recurrent cubital tunnel syndrome after previous surgery.
