The cases of two patients, a four-year-old boy and an eight-year-old boy, who had been incapable of active flexion of the little finger since birth, are presented. They were capable of active flexion of the metacarpophalangeal (MP) joint, but not of the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints. They were diagnosed with a defect of the flexor digitorum profundus (FDP) tendon of the little finger and underwent surgery. In both cases, the FDP tendon turned into fibrous tissue proximal to the palm and lost continuity on this side. Reconstruction was performed by making an end-to-side anastomosis of the residual proximal end of the FDP tendon to the FDP tendon of the ring finger in the palmar region. Although one patient required repeated surgery due to post-operative tendon adhesion, good outcomes were achieved, with both patients becoming capable of active flexion.

A case of rupture of flexor digitorum profundus tendon of the little finger caused by calcification of the triangular fibrocartilage (TFC) is reported. At operation, a round defect of the TFC and rupture of the flexor digitorum profundus tendon (FDP) of the little finger were observed. The defect of TFC was repaired using the palmaris tendon and FDP of the little finger was woven into FDP of the ring finger. Eleven months after operation, the patient had almost full flexion and extension of the distal and proximal interphalangeal joints.

This study was done to identify whether the dimensions of the distal phalanges allow suture anchor fixation of the flexor digitorum profundus tendon. Forty pairs of hands were dissected to measure the anteroposterior and lateral dimensions of distal phalanges of all digits. The mean anteroposterior depth of the distal phalanx at the insertion of the tendon was found to be 4.7 mm for the little finger, 5.4 mm for the ring finger, 5.9 mm for the middle finger, 5.4 mm for the index finger and 6.9 mm for the thumb respectively. The commonly available anchors and drill bits for fingers were found to be suboptimal for anchoring the flexor digitorum profundus tendon to the distal phalanx of the little finger. The drill bits used for these anchors were found to be too long for the little fingers and some ring and index fingers.

Asymptomatic pisotriquetral arthroses caused ruptures of the flexor digitorum profundus tendon of the little finger in 2 elderly patients. Ruptures occurred with unnoticeable onset, and bilateral ruptures separately occurred with interval of several years in one patient. The tendon was ruptured in zone IV with perforation of the gliding floor through which the degenerative pisiform was visible. The gliding floor was repaired followed with excision of the pisiform, and the ruptured tendon was then transferred to the profundus tendon of the ring finger. Asymptomatic pisotriquetral arthrosis in old age can be an aspect of the pathological background of flexor tendon ruptures of the little finger that occur unnoticed.

Flexor Digitorum Profundus Tendon

Flexor digitorum profundus (FDP) tendon avulsion from the distal phalanx is a well recognised injury, which usually follows a hyperextension force to a flexed distal interphalangeal (DIP) joint. It is commonly seen in contact sport athletes, with a predilection for the ring finger.2,4 Avulsion of the FDP tendon from pathological bone is an infrequent occurrence. It has, however, been reported to occur in association with an enchondroma of the distal phalanx.2,3 To our knowledge, an FDP tendon avulsion through a recurrent enchondroma has not been reported. We present the case findings of such an event.

Potential Use

Closed ruptures of the flexor digitorum profundus (FDP) tendon cause a loss of active flexion at the distal interphalangeal joint. Commonly referred to as a ‘jersey finger’ because of its association with tackling sports, the distal aspect of FDP is avulsed from its insertion on the distal phalanx in zone I, with or without a fragment of bone. Because of this classic injury mechanism and pattern, providers may not seek advanced imaging beyond plain radiographs. Although rare, injury to FDP more proximally may occur. More often this injury is associated with a weak underlying tendon because of repetitive microtrauma or anomalous anatomy, for example. We present a case of a closed rupture of the FDP in zone III, and stress the importance of maintaining a high clinical suspicion and the potential use of adjunct ultrasound imaging to localise the site of injury.

ABSTRACTClosed rupture of the FDP tendon is rare. However, whenever they occur the most common site of rupture is the tendon-bone insertion, less frequent site is at the musculo-tendinous junction. Midsubstance ruptures are even more unique and are usually due to underlying pathology such as fracture, cystic degeneration, rheumatoid arthritis, or sequel following local steroid injection. This report describes a closed rupture of FDP tendon of little finger. Mechanism of injury, diagnosis and management are discussed.

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.

The vinculum breve of the flexor digitorum profundus tendon was found to apply traction to the volar plate on flexion of the distal interphanageal joint. It was also observed that the check-rein ligaments of the joint only became taut in the hyperextended position. This may account for the greater amount of passive hyperextension that can be achieved at the distal than the proximal interphanageal joint.
