Reconstructive Technique

Postburn nailfold retraction often results in nail deformity and loss of distal interphalangeal joint flexion. A technique of reconstruction of the nailfold using a proximally based transposition flap is described in a patient with postburn nailfold retraction of the left thumb, index and middle fingers.

Four non-invasive tests for central slip integrity were analysed using 20 fresh frozen cadaver fingers. A pre-boutonnière deformity was simulated by dividing the central slip. A passively correctable boutonnière was simulated by dividing the central slip, triangular ligament and oblique fibres of the extensor expansion. The test described by Boyes, which evaluates distal interphalangeal joint flexion, was found not to be reliable for the diagnosis of either injury. The test described by Elson, which evaluates distal interphalangeal joint rigidity while actively extending the flexed proximal interphalangeal joint, was the only manoeuvre which was able to discern central slip integrity in both simulated injuries. The central slip tenodesis test and testing resistance of active proximal interphalangeal joint extension should be performed with the proximal interphalangeal joint in flexion to weaken the effectiveness of the lateral bands.

Purpose: This study assesses the influence of A2 pulley integrity on the strength of the repair. Method: Part 1- The flexor digitorum profundus (FDP) tendons of 72 Cobb chicken feet were severed and repaired in the region of the A2 pulley using a modified Kessler core suture and an epitendinous suture. The A2 pulley was either left intact, divided for 50% of its length, or divided in its entirety. The distal interphalangeal joint was fixed at a position of 20°, 40° or 60° of joint flexion. The load to failure, integrity of the A2 pulley and the site of tendon failure were analysed. Part 2- A further 32 chicken feet were used to exclude the effects of freezing and thawing on results and to analyse differences when using a core suture only. Results: No difference in failure load between any of the test groups or subgroups was identified. The integrity of the A2 pulley was preserved in all specimens. The most common cause of failure was distal suture pull-out. Discussion: This study does not demonstrate that release of the A2 pulley provides an advantage in increasing tendon repair strength. Division of 50% of the A2 pulley does not predispose to pulley rupture. Flexor tendon repair strength did not alter with distal interphalangeal joint flexion between 20° and 60°. Clinical Relevance: The findings of this study do not support division of the A2 pulley to prevent flexor tendon repair failure if repair methods of appropriate strength are utilised.

A prospective review was carried out to evaluate the outcome of surgically repaired open central slip (zone III) injuries which were treated with 3 weeks of proximal interphalangeal joint immobilization within a cylinder splint and then with 3 weeks of controlled mobilization within a Capener coil splint. Thirty-one fingers in 27 patients were assessed by the same independent therapist. All fingers achieved an excellent or good recovery with a mean proximal interphalangeal joint flexion of 94° (range 70–110°) and a mean distal interphalangeal joint flexion of 57° (range 30–81°). Extension deficits of the proximal interphalangeal joint were noted in five fingers (mean 6°, range 3–15°). The results show that a combination of immobilization and controlled mobilization is an effective rehabilitation regime for surgically repaired open central slip injuries.
