TRIGGER FINGER CAUSED BY AN OLD PARTIAL FLEXOR TENDON LACERATION: A CASE REPORT

We report a rare case of trigger finger caused by an old partial laceration of the flexor digitorum superficialis. The triggering occurred five months after injury. This case was the latest presentation of triggering in the literature. The patient was managed by incising the A1 pulley and suturing the flexor tendon flap after trimming. He was relieved of triggering and there was no recurrence.

Surgical treatment for trigger finger involves division of the A1 pulley. Some surgeons perform an additional step of traction tenolysis by sequentially bringing the flexor digitorum superficialis and flexor digitorum profundus tendons out of the wound gently with a Ragnell retractor. There is currently no study which states whether flexor tendon traction tenolysis should be routinely performed or not. The objective of this study is to compare the outcome in patients who have traction tenolysis performed (A group) versus those who did not have traction tenolysis (B group) performed. It was noted that even though the mean total active motion (TAM) for the B group in our study was lower preoperatively, it was consistently higher than the A group in all the 3 post-operative visits demonstrating a better outcome in the B group. Even though it was not statistically significant, our data also showed that patients with traction tenolysis appeared to have more postoperative pain compared to those without.

A 59-year-old man suffered from subcutaneous rupture of the flexor tendon of the little finger associated with fracture of the hook of hamate. He could not flex his little finger completely at the distal interphalangeal joint, but incomplete flexion of the proximal interphalangeal joint was possible. Surgical exploration revealed anomaly of the flexor digitorum superficialis of the little finger, as it originated from the palmar aspect of the carpal ligament, and a small portion of the muscle belly was traversed toward the A1 pulley over the profundus tendon and then it ran into the A1 pulley as a normal superficialis tendon. The flexor digitorum superficialis of the little finger is well known to show variations, but our case is extremely rare, and furthermore there are no reports in the available literatures about the function of this anomalous muscle.

A 39-year-old woman sustained a small wound on the palm of her right hand, which quickly healed naturally; however, a month later pain and limited range of motion were noted in her right finger. Surgery revealed the radial half of the flexor digitorum superficialis (FDS) tendon was ruptured and formed a flap, which hooked at the entrance of the A1 pulley. The proximal stump was sutured to the remaining ulnar (normal) side of the FDS tendon. Locking occurs between the tendon flap and the tendon sheath; therefore, when there is no fibrous tendon sheath near the partially ruptured tendon, locking will not occur.

Objective: This study aims to compare the morphology of the A1 pulley and flexor tendons in idiopathic trigger finger of digits other than the thumb between in neutral position and in the position with the interphalangeal joints full flexed and with the metacarpophalangeal (MP) joint 0° extended (hook grip position). Method: A total of 48 affected digits and 48 contralateral normal digits from 48 patients who initially diagnosed with idiopathic trigger finger were studied sonographically. Sonographic analysis was focused on the A1 pulley and flexor tendons at the level of the MP joint in the transverse plane. We measured the anterior-posterior thickness of A1 pulley and the sum of the flexor digitorum superficialis and profundus tendons, and also measured the maximum radialulnar width of the flexor tendon in neutral and hook grip positions, respectively. Each measurement was compared between in neutral and in hook grip positions, and also between the affected and contralateral normal digits in each position. Results: In all the digits, the anterior-posterior thickness of flexor tendons significantly increased in hook grip position as compared with in neutral position, whereas radial-ulnar width significantly decreased. Both the A1 pulley and flexor tendons were thicker in the affected digits as compared with contralateral normal digits. Conclusion: The thickness of flexor tendons was significantly increased anteroposteriorly in hook grip position as compared with in neutral position. In trigger finger, A1 pulley and flexor tendon were thickened, and mismatch between the volume of the flexor tendon sheath and the tendons, especially in anterior-posterior direction, might be a cause of repetitive triggering.

Trigger finger was observed in a patient with a healed laceration at the palmar-digital crease of the left long finger. Examination revealed complete transection of the ulnar slip of the FDS tendon. The proximal ulnar slip was excised and the cut edge tapered, which restored a full range of motion without triggering.
