[Treatment of chronic mallet finger with tendon flap graft. Report of 16 cases].

A series of 16 cases of chronic mallet finger deformity repaired with tendon flap from palmaris longus tendon or lateral band of extensor tendons is reported. Follow-up ranged from 1 to 4 years, the deformity has been corrected and pain disappeared in all cases. The active extention of DIP joints are 0 degrees in 12 cases and 5 degrees-15 degrees hyperextention in 4 cases. The active flexion of DIP joints are normal (65 degrees-80 degrees) in 11 cases, has 5 degrees-15 degrees flexion lag in 5 cases. The PIP and MP are normal in all cases. The anatomic basis of this procedure is narrated. The restoration of the anatomic continuity of the terminal extensor tendon reestablishes the coordinative effect between the long extensor tendon, intrinsic lateral band and oblique retinacular ligament and thus brings good long term result.

In vivo flexor tendon forces increase with finger and wrist flexion during active finger flexion and extension.

The effects of different hand motions and positions used during early protected motion rehabilitation on tendon forces are not well understood. The goal of this study was to determine in vivo forces in human flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendons of the index finger during active unresisted finger flexion and extension. During open carpal tunnel surgery (n = 12), flexor tendon forces were acquired with buckle force transducers, and finger positions were recorded on video while subjects actively flexed and extended the fingers at two different wrist angles. Mean in vivo FDP tendon forces varied between 1.3N +/- 0.9 N and 4.0 N +/- 2.9 N while mean FDS tendon forces ranged from 1.3N +/- 0.5 N to 8.5 N +/- 10.7 N. FDP force increased with active finger flexion at both wrist angles of 0 degrees or 30 degrees flexion. FDS force increased with finger flexion when the wrist was in 30 degrees flexion, but was unchanged when the wrist was in 0 degrees of flexion. Tendon forces were similar regardless of whether the fingers were moving in the flexion or extension direction. Active finger flexion and extension with the wrist at 0 degrees and 30 degrees flexion may be used during early rehabilitation protocols with limited risk of repair rupture. This risk can be further decreased for a FDS tendon repair by reducing wrist flexion angle.

Repair of digital nerve defect with autogenous vein graft during flexor tendon surgery in zone 2.

Autogenous vein graft was used to fill 18 digital nerve defects between 0.5 to 5.8 cm in length during flexor tendon surgery in zone 2. The vein was taken from the forearm and reversed to bridge the digital nerve. For nerves with defects over 2.0 cm, normal nerve slices were inserted inside vein conduits. Recovery of sensibility was evaluated by von Frey test, pin-prick detection, localization of stimulus, moving two-point discrimination and sweating on the finger pulp. Follow-up revealed excellent recovery in two digital nerves, good in nine, fair in five and poor in two. The results suggest that vein graft provides a simple and practical method to reconstruct a digital nerve defect during tendon repair in zone 2.

Tension wire fixation of avulsion fractures in the hand.

Tension band wiring is a simple, predictable method of internal fixation for avulsion fracture in the hand. These fractures include the bony gamekeeper, bony mallet, and fractures associated with proximal interphalangeal joint trauma. By the placement of a small gauge wire through the insertion of the ligament or tendon onto the fracture fragment, the tension wire technique avoids many of the pitfalls of internal fixation and also takes advantage of its physiologic and biomechanical position.

Treatment of the chronic boutonniere deformity by extensor tenotomy.

A patient with a chronic boutonniere deformity often experiences more difficulty because of the hyperextension deformity at the distal joint, rather than the lack of extension at the proximal interphalangeal joint. It is in these cases that restoration of flexion at the terminal joint by tenotomy of the terminal extensor tendon is of most value.

[Reconstructive augmentation of the metacarpal tendons].

When splitting a metacarpal pulley, a diagonal incision allows, after sliding its margins and suturing them, to restore a pulley larger than before. With a small counter incision, it is possible to have a yet larger one. It is a very proper way to treat a "trigger finger". A similar technique may be used in flexor tendons lacerations, which make possible the suture of both tendons. This technique permits the tenolysis with pulley reconstruction.

[Soft tissue reconstruction of the finger with free, posterior ramus of the anterior interosseous artery-based septo-cutaneous flap. Anatomy--technique--case examples].

In cases of larger soft-tissue defects of the fingers which cannot be covered with local or regional flaps, pedicled or even free flaps can be used. Pedicled flaps and most free flaps are too bulky and need several trimmings before a cosmetically and functionally satisfactory result is achieved. Free flaps used for soft-tissue reconstruction in digits should be thin and should have a low donor-site morbidity. The free flaps based on the anterior interosseous artery, especially the one based on the dorsal branch, are ideal for soft-tissue reconstruction of single digits. They are very thin and can be harvested in the same operative field. Donor-site morbidity is usually low. The clinical usefullness of this flap is shown in the reconstruction of three consecutive cases of severely damaged fingers.

MR imaging of the finger tendons: normal anatomy and commonly encountered pathology.

MR imaging has emerged as a powerful tool in the evaluation of soft tissue structures such as the tendons of the hand and finger due to its excellent soft tissue contrast and multiplanar imaging capabilities. In the finger and hand, perhaps more than in any other location in the body, a detailed and intimate understanding of anatomy is crucial for lesion localization, directing clinical management and predicting long-term prognosis. These issues are of paramount importance to both the clinician and imager, both faced with the challenge of the complex anatomy and pathology associated with these delicate structures. The anatomy of the finger including intrinsic and extrinsic muscles, retinacular structures, and tendons will be discussed. The MR imaging features of common lesions of the tendons of the hand and finger will be reviewed.

Reverse neurovascular homodigital island flap.

We describe a homodigital island flap with a reverse vascular pedicle based on the anastomoses between the radial and ulnar digital arteries. These anastomotic branches lie between the posterior wall of the tendon sheath and the periosteum to form the three digitopalmar arches. The vascularization of the reverse homodigital island flap is obtained using the middle transverse palmar arch. This flap was performed in 11 patients as a neurovascular "sensitive" flap, including the digital nerve in the pedicle, which was then sutured to the contralateral one at the defect. This technique achieves cover of the tactile pad in one operative stage and provides well-vascularized skin, allowing early mobilization. The quality of skin cover was confirmed in all the patients at follow-up ranging from 7 to 43 months postoperatively. We believe that the benefits of the procedure outweigh the disadvantages related to the section of the digital nerve and artery.

The effects of a shortened postoperative mobilization programme after flexor tendon repair in zone 2.

The effects of a shortened post-operative mobilization programme following flexor tendon repair in zone 2 in the hand were examined in a prospective, randomized study. 91 digits in 82 patients were included in the study. All injured tendons were repaired within 24 hours and all patients were subjected to the same mobilization programme during the first 6 weeks using a passive flexion-active extension régime. After 6 weeks the patients were randomized into two groups; in group A full activity was allowed after 8 weeks while in group B unrestricted use of the injured hand was not allowed until 10 weeks after the tendon repair. Functional results were compared using the Louisville, Tsuge and Buck-Gramcko assessment systems. Grip-strength was measured 16 weeks after repair, subjective assessment of hand function was recorded on a visual analogue scale, and absence from work was registered. No significant differences were observed between the groups regarding functional results, rupture rates, grip strength or subjective assessment, but absence from work was reduced by 2.1 weeks with the shorter mobilization programme. Using the described régime, full activity can be encouraged 8 weeks after flexor tendon repair in zone 2 of the hand without adverse effects on functional results or increased risk of rupture of the repair.

A combined regimen of controlled motion following flexor tendon repair in "no man's land".

A program of controlled motion following repair of flexor tendons in the hand is presented. This regimen incorporates the features of active extension against rubber band passive flexion, as well as those of controlled passive extension and passive flexion. In this prospective study, 44 digits with complete lacerations of the flexor digitorum profundus and flexor digitorum superficialis in zone 2 were treated. Using the Strickland formula of total active motion of the interphalangeal joints, 36 fingers (82 percent) were rated "excellent"; 7 fingers (16 percent) were rated "good"; 1 finger (2 percent) was rated "fair"; none was rated "poor". There was no statistical difference between the results of delayed primary repair and immediate primary repair.
