Abstract:A thumb lacking intrinsic muscle function but having extrinsic flexion will hyperflex in the interphalangeal joint giving a positive Froment's sign. This can effectively be prevented with split flexor pollicis longus tenodesis. The mean postoperative range of motion in the IP joint of 39 hands was 28 (18) degrees and 23 (20) degrees six and 12 months postoperatively. The procedure makes arthrodesis (temporary or permanent) superfluous. This procedure can be recommended strongly.
“…Researching the literature, we found 2 previous reports on functional surgery in NT tetraplegia. One patient operated in our unit (patient number 5) was mentioned in a series of flexor pollicis longus distal thumb tenodesis, but no details of the overall surgical concept and result of the bilateral reconstruction were given (21). landi and co-workers (22) reported a highly exceptional case of a boy with incomplete paralysis after transverse myelitis in whom upper extremity surgery ultimately led to deterioration of his overall functional level.…”
Individuals with stable non-traumatic tetraplegia benefit from surgical rehabilitation of their upper extremities. The number of non-traumatic spinal cord injuries is likely to increase as lifespan increases worldwide, and further research into the functional rehabilitation of this population will therefore become increasingly relevant.

“…12 Reconstructive arm and hand surgery has the potential to improve both passive and active function in the arm and hand in patients with cervical SCI. 13,14 The basis for treatment is the patient's needs and desires as well as the remaining motor and sensory functions in the upper extremities, with no restrictions related to age or time since injury. 15 Even though hand function is of the utmost importance for independence in ADL, the evaluation of reconstructive hand surgery has hitherto been focused more on assessing function than activity.…”

Hyperflexion of the thumb interphalangeal (IP) joint interferes significantly with pinching between the thumb and the index finger in a paralyzed hand. The extensor pollicis longus-loop-knot (ELK) procedure was used successfully in 7 tetraplegic patients to balance the IP joint between strong restored flexor function and lacking or weak antagonism of the thumb extensors. A V-shaped incision was made over the extensor hood at the level of the IP joint, the extensor pollicis longus (EPL) tendon was elevated, a loop was formed, secured by sutures, and then turned proximally onto the EPL tendon itself and fixed on both sides. The operation reliably limited the maximum range of IP flexion at 20 to 30 degrees from neutral. Postoperative problems did not occur. The ELK procedure is easy and quick and secures the optimal setting of IP flexion with limited flexibility, which is advantageous compared with rigid bony arthrodesis. It also avoids certain disadvantages of the commonly used flexor pollicis longus split tenodesis and is therefore a valuable alternative for the correction of Froment's sign due to intrinsic or extrinsic paralysis of the thumb.
