Flexor Digitorum

In five of six cases of camptodactyly in which an abnormality of the flexor tendon was examined at operation, the flexor digitorum superficialis tendon was hypoplastic and there was no continuity of the normal tendon between the muscle belly and bony insertion. The proximal end of the flexor digitorum superficialis tendon was attached to the palmar aponeurosis and the flexor tendon sheath of the ring finger in two patients, to the palmar aponeurosis in one, to the undersurface of the transverse carpal ligament in one and to the flexor tendon sheath of the ring finger in one. The tenodesis effect of the abnormal tendon of the flexor digitorum superficialis is considered to play an important role in the cause and rapid increase of the deformity of camptodactyly.

Delayed rupture of a flexor tendon in the hand due to the presence of a retained foreign body is rare. We present the case of a late flexor pollicis longus rupture 30 years after traumatic implantation of a glass fragment. The foreign body had migrated distally a distance of 4.5 cm from the site of the original injury and eroded into the flexor tendon sheath. Thumb function was restored with a flexor digitorum superficialis tendon transfer from the ring finger with excellent results.

Spread Of Infection

Previous descriptions of the pattern of communication between the digital flexor tendon sheaths have been largely based on imaging studies. An anatomic study on 12 cadaveric hands was conducted using water soluble dye and directly observed patterns of communication between the digital flexor tendon sheaths and the radial and ulnar bursae. Four out of twelve specimens (33%) demonstrated a communication between the radial and ulnar bursae. The ulnar bursa communicated with the ring finger flexor sheath in two specimens, and the index finger flexor sheath in two specimens. One hand (8.3%) showed communication between the middle finger tendon sheath and radial bursa and between the index finger flexor tendon sheath and radial bursa. These findings show a considerable level of variation in communicating patterns between the synovial sheaths of the hand and wrist. Clinicians should be aware of the possibility of variations to the classical presentation of spread of infection through the digital flexor sheaths.

Partial Division

A case is reported where a flap cut of the radial slip of the flexor digitorum superficialis triggered on the proximal border of the A2 pulley within a healed intact tendon sheath. Shaving the flap resolved the problem. This illustrates another post-traumatic mechanical cause of triggering after partial division of flexor tendons.

A 12-year-old boy had camptodactyly of the little finger. Operative findings revealed an abnormal origin of the lumbrical muscle from the transverse carpal ligament, and abnormal insertion into the tendon sheath of the flexor digitorum superficialis tendon. No similar case has been reported in the literature.

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.

AbstractChondromas of soft tissue are benign and relatively rare lesions. Proper clinical examination supplemented by radiologic and histopathologic examination is necessary to diagnose this entity. This must be differentiated from malignant soft tissue neoplasm like chondrosarcoma to avoid unnecessary radical treatment. We came across a similar case of soft tissue enchondroma of the left-hand ring finger in a young 20-year-old male patient. It was arising from tendon sheath. Complete excision of the lesion was performed with preservation of flexor tendon and tendon sheath. The patient had an uneventful recovery with no sign of recurrence 6 months postoperatively.

Flexor Digitorum

Background: Transposition of the flexor digitorum longus tendon has been widely reported for the correction of flexible claw and hammer toe deformities. Only transposition of the flexor digitorum brevis tendon has been reported in the literature in a cadaveric study that used the dorsal and plantar approach. A search of the literature revealed no reports of transposition of the flexor digitorum brevis tendon for treatment of these conditions through a unique dorsal cutaneous incision. We performed a cadaveric study to determine whether the flexor digitorum brevis tendon is long enough to be transferred to the dorsum of the proximal phalanx of the toe from its lateral or medial aspect through a unique dorsal cutaneous incision. Methods: Transposition of the flexor digitorum brevis tendon was attempted in 156 toes of cadaveric feet (52 each second, third, and fourth toes) through a unique dorsal incision. Results: The flexor digitorum brevis tendon was long enough to be successfully transposed in 100% of the second, third, and fourth toes by the dorsal incision approach. Conclusions: Transfer of the flexor digitorum brevis tendon to the dorsum of the proximal phalanx can be performed for the correction of claw and hammer toe deformities, especially in the second, third, and fourth toes. The meticulous longitudinal incision of the flexor tendon sheath to expose the flexor digitorum brevis tendon is essential to the success of the procedure.

Distal Aspect

A six-year-old warmblood horse was presented with a longstanding frontlimb lameness with mild digital flexor tenosynovitis and swelling of the distomedial pastern. Ultrasonography and magnetic resonance revealed a dense mass lesion in the distal aspect of the digital flexor tendon sheath, with a partial lamellar architecture, absence of internal vascularization and adjacent smooth pressure osteolysis of the middle phalanx. After surgical excision, histopathology confirmed an epithelial inclusion cyst. Epithelial inclusion cysts, also known as keratinizing or follicular cysts, are expansile benign mass-like lesions of aberrant epidermal tissue. In the horse, they are known to occur in cutaneous and several non-cutaneous tissues. In the digital flexor tendon sheath, they have rarely been described. Given their often chronic presentation in this location, they may appear as an atypical dense mass on imaging, uncommon for cystic lesions. Complete tenoscopic removal, even for larger masses, is achievable and considered curative with good prognosis for return.
