144 participants in 2 patient groups

moderate cubital tunnel syndrome

Experimental group

Description:

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.

Treatment:

Procedure: anterior intramuscular transposition

Procedure: anterior subcutaneous transposition

Procedure: simple decompression

severe cubital tunnel syndrome

Experimental group

Description:

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.

Treatment:

Procedure: anterior intramuscular transposition

Procedure: anterior subcutaneous transposition

Procedure: simple decompression
