Little Finger

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.

Background: The aim of this study was to assess the height of nonunion formation injuring the ulnar-side finger flexor tendon, the positional relationship between the hook of the hamate and little finger flexor tendon was evaluated on CT scans. Methods: The subjects were 20 healthy patients (40 hands) (14 males and 6 females, mean age: 28 years old). Their hands were imaged in extension and flexion of the fingers on CT. The position of the little finger flexor tendon was determined regarding the height of the hook of the hamate as 100%. Results: The heights of the flexor digitorum profundus tendons were 46 ± 6% in extension and 44 ± 9% in flexion, and those of the flexor digitorum superficialis tendons were 87 ± 8% in extension and 91 ± 9% in flexion. Conclusions: Our study suggested that 40% of the base of the hook of the hamate does not contact with the flexor tendon, suggesting that flexor tendon injury is unlikely to occur in that region.

Trigger fingers with proximal interphalangeal joint flexion contracture are suggested to have a poorer response to corticosteroid injection than those without contracture, though this has not been proven scientifically. We compared the clinical response to corticosteroid injection between trigger fingers with and without proximal interphalangeal joint contracture, and investigated the influence of the injection on the A1 pulley and flexor digitorum tendons using ultrasonography. One month after injection, pain was significantly reduced in the no contracture group, and 56% of trigger fingers with proximal interphalangeal joint contracture resolved. Before injection, relative thickening of the A1 pulley and flexor digitorum tendons, and a partial hypoechoic lesion of the flexor digitorum superficialis tendon were observed in the contracture group. One month after injection, the thickening of the tendons and the A1 pulley was reduced, but the partial hypoechoic lesion was still observed in significant numbers. We have demonstrated that the presence of a proximal interphalangeal joint contracture was associated with a reduced clinical response to corticosteroid injection, and we suggest that the pathologic change in the flexor digitorum superficialis tendon, represented by the partial hypoechoic lesion, contributed to corticosteroid injection resistance.

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.

Synovitis is a type of aseptic inflammation that occurs within joints or surrounding tendons. No previous reports have described a hypertrophic synovium eroding the tendon sheath and manifesting as synovitis within the flexor tendon. We herein report a case involving a 10-year-old girl who presented to our hospital with a 1-month history of a swollen mass and progressive inability to completely flex her left index finger. The active flexion angle of the proximal interphalangeal joint was limited to 85°. A longitudinal incision of the flexor digitorum profundus tendon was surgically performed. The synovium inside and outside the flexor digitorum profundus tendon was completely removed. After the surgical excision, normal tendon gliding returned without recurrence by the 1-year follow-up. The active flexion angle of the proximal interphalangeal joint improved to 100°. To the best of our knowledge, this is the first case of synovitis affecting the flexor tendon and leading to limited flexion of a finger. The manifestation of a double ring sign on magnetic resonance imaging is quite characteristic. Early diagnosis and monitoring of the hyperproliferation and invasiveness of the synovial tissue are required. Surgical excision can be a simple and effective tool when necessary.

The button-over-nail technique is commonly used to fix the core suture to the distal phalanx for flexor digitorum profundus repairs in zone 1. We report a retrospective study of 23 consecutive patients who had a repair of the flexor digitorum profundus tendon in zone 1 using the button-over-nail technique. Fifteen patients experienced a complication, of which ten were directly related to the button-over-nail technique. Complications included nail deformities, fixed flexion deformities of the distal interphalangeal joint, infections and prolonged hypersensitivity. Two patients required amputation of the fingertip. We recommend that the button-over-nail technique should be avoided or used only with caution and with close attention to the details of the technique.

Lacerations are the major cause of flexor tendon injury in zone I and they are most commonly missed due to incomplete examinations. We report a case of lacerated flexor tendon injury in Zone I closed without explorations and which was referred to occupational therapy with the diagnosis of stiff hand. The patient received therapy for his stiff hand following which he could flex the distal interphalangeal joint (DIP) on blocking the proximal interphalangeal joint but failed to flex his DIP joint on making a composite fist. With resistive testing the patient failed to initiate resistance on flexion. The patient was referred back to the hand surgeon and subsquently diagnosed with a flexor tendon injury.

Two cases are described with full flexion of the proximal interphalangeal joint produced by an intact short vinculum after complete laceration of both superficialis and profundus tendons. To establish the clinical diagnosis of complete flexor digitorum superficialis division, the necessity of examining the flexion strength of an injured finger is emphasized.

Congenital swan neck deformities in seven fingers of two patients were treated by transfer of the flexor digitorum superficialis tendon to a tendon graft which was attached the extensor aponeurosis over the middle phalanx. The tendon transfer is protected for at least 2 months by a modified Murphy splint.
