Pre-post
N=15

Population: Age range: 19-70 yr; Type of SCI: traumatic=12, non-traumatic=3; Level of injury: tetraplegia=15, paraplegia=0; Mean time since SCI: 54.2±42.8 mo; International classification of patients’ upper extremities: OCu4-OCu8 (with one patient who was exceptional).
Treatment: All patients had their extensor digiti minimi (EDM) tendon transferred to the abductor pollicis brevis (APB) through the interosseous membrane, in addition to ≥3.2 procedures to restore key pinch.
Outcome Measures: Maximum distance between the thumb and index finger tips during active or passive opening of the hand, maximum angle of palmar abduction, grip and key pinch strength, and active finger range of motion.
  1. Active thumb-index opening increased significantly from 2.5 (SEM 1.0) cm before surgery to 9.0 (SEM 0.8) cm after surgery.
  2. Nine patients without previous active opening of the first web space recovered a mean thumb-index opening of 9.1 (SEM 1.7) cm; this distance increased an average of 2.9 (SEM 0.8) cm in six patients who had active thumb-index distance of 6.3 (SEM 1.6 cm) before surgery
  3. 14/15 patients were able to direct and coordinate key pinch and perform tasks using restored APB function including five patients whose EDM strength was rated as grade 3 before the transfer.

Case Control
N=12

Population: Treatment group (n=6): Mean age: 32.2±4.9 yr (25-56); Gender: males=4, females=2; Control group (n=6): Mean age: 31.2±5.0 yr (19-52); Gender: males=4, females=2.
Treatment: Individuals in the treatment group had a brachioradialis (BR) to Flexor pollicis longus (FPL) transfer dorsal to radius through the interosseous membrane whereas the control group received traditional palmar BR to FPL.
Outcome Measures: Lateral key pinch and pronation range of motion.
  1. Post-operative active pronation was significantly greater in the dorsal transfer group in comparison to the palmar group (149±6° and 75±3°, respectively).
  2. Pinch strength was similar between both groups (1.28±0.16 kg and 1.20±0.21 kg), respectively.
  3. It is feasible to reconstruct lateral key pinch and forearm pronation simultaneously using only the BR muscle.

Case Series
NInitial=29; NFinal=24

Population: Mean age=42.9 yr; Time since injury=20.5 yr; Time since surgery=15.1 yr; Handedness: right=22, left=24; Level of Injury: 01: 6 hands; 02: 3 hands; 03: 5 hands; 0Cu2: 2 hands; 0Cu3: 6 hands; 0Cu4: 17 hands; 0Cu5: 8 hands; 0Cu6: 1 hand; tetraplegia.
Treatment: Surgery.
Outcome Measures: Lamb and Chan questionnaire with additional 10 Burwood questions; Swanson sphygmomanometer (hook grip); Preston Pinch Meter (key pinch); Quadriplegic index of Function (QIF); Digital Analyzer (key and grip pinch)
  1. Elbow Extension: bilateral surgery 9/11 subjects; Hook Grip; 17 right hands (av. Grip 46.2 mm Hg in 1991; improved slightly, not statistical significant (p=0.30)) Left hand: 15 hands: significant increase (p=<0.001), av. 28.7 mmHg to 53.2 mmHg; no statistical significance between right and left hook grip as measured by SGM and DA in 2001 (p=0.93 and p=0.97).
  2. Key Pinch: av. key pinch 20 right thumbs in 1991 25.8 N and decreased in time to av. 13.9 N (significant decrease p=<0.001); average pinch strength 18 left thumbs decreased from 17.7 to 8.8 N (significant decrease p=<0.001). Average pinch strength measured by DA, increase in key pinch when compared to 1991, significant for both right (p=0.01) and left (p=0.01) thumbs.
  3. Active Transfer Vs. Tenodeses: hook grip: active transfers 2x strength of tenodeses in 1991 (p=0.05) and 2001 (p=0.03). Pinch grip: similar to 1991 data (p=<0.001), 2001 data does not follow trend. 2001 DA data did not reach significance (p=0.06).
  4. Longitudinal Comparison: hook grip strength 25 hands with active transfers significant increase 42.1 to 60.2 mm Hg (p=<0.001) and pinch grip increase from 24.0 to 38.4 N in 31 thumbs that had active transfers using 2001 DA data (p=0.03). Hook strength obtained from a tenodesis in 7 hands did not weaken over time (p=0.05) but pinch strength in 7 thumbs significantly increased (p=<0.001) using 2001 DA data.
  5. Questionnaire results; Lamb and Chan activity measure: showed perceived improvement of functional activities significantly lower in 2001 (p=<0.001). QIF scores of current functional independence was significantly better (p=0.004). Additional Burwood questionnaire showed levels of satisfaction, perceived expectation, gratification and opportunity enhancement were maintained over time (p=0.281).

Most significant improvement in basic activities such as washing, eating and using the toilet, hold glasses and cups, wash limbs and brush hair, turn on taps, improve bladder compression, insertion of suppositories, change from complete reliance on other for self-care, more mobile, 7 able to drive a car. Improvement in UL function facilitated development of personal interests.
