Tendon Transfers

Description
-
Findings consistent with incomplete median nerve palsy
-
Intact flexion at proximal interphalangeal joints.
-
Loss of distal interphalangeal joint flexion of index and long finger and interphalangeal joint of thumb.
-
Loss of thumb palmar abduction.
-
Flexion present in right ring and small fingers.
-
Work-up
History
-
Age, gender, handedness, and occupation of the patient.
-
Timing and mechanism of injury
-
Trauma: Associated injuries, underlying fractures, dislocations, neurovascular insult.
-
Infection: Nature of infection (bacterial, fungal, other), operative management to date (incision and drainage), antimicrobial medications, local versus systemic signs and symptoms.
-
Tumor ablation: Tumor pathology, margins, planned radiation and chemotherapy.
-
-
Previous injury or surgery to the hand in question.
-
Manual demands of daily living and overall lifestyle.
-
Past medical and surgical history.
-
Social history including smoking status and substance abuse.
Physical examination
-
Location and type of original injury.
-
Functional deficit.
-
Motor function (discern neurologic function based on motor examination findings).
-
Sensory function.
-
-
Vascular status of hand (intact palmar arch).
Pertinent imaging or diagnostic studies
-
Standard radiography (three views of the hand).
-
Computed tomography if further detail required regarding bony structures (especially carpal bones).
Consultations
-
Physical/occupational therapy
-
If joints are not sufficiently supple, they must be loosened, preferably by hand therapy.
-
If hand therapy fails, surgical release of the joints may be required before tendon transfer.
