Traumatic boutonniere deformity of the thumb

We report three patients who presented 3 to 8 months after sustaining a closed injury to the dorsoradial aspect of the metacarpophalangeal joint of the thumb. All three patients had an extensor lag of the metacarpophalangeal joint and paradoxical hyperextension of the interphalangeal joint. There were no collateral ligament injuries. The patients required surgical treatment which included advancement and reattachment of the extensor pollicis brevis insertion and imbrication of the dorsoradial capsule to restore the anatomical alignment of the extensor pollicis longus. Surgical treatment of dorsoradial injuries to the thumb metacarpophalangeal joint may be required for injuries that result in subluxation of the extensor pollicis longus tendon and a boutonnière deformity of the thumb.     

Volar dislocation of the metacarpophalangeal joint of the thumb--a case report

A patient with a volar dislocation of the metacarpophalangeal joint of the thumb is reported in which closed reduction proved impossible because of the interposition of the dorsal capsule, extensor pollicis longus tendon and extensor pollicis brevis tendon in the metacarpophalangeal joint. The collateral ligament was also ruptured. Therefore open reduction is recommended for similar cases.     

Combined reconstruction of volar and radial instability of a thumb metacarpo-phalangeal joint

The purpose of this paper is to present a case of the combined volar and radial ligament instability of a thumb metacarpophalangeal joint secondary to trauma. A successful reconstruction of the volar capsule and the radial collateral ligament was achieved using the tendon of the extensor pollicis brevis.     

Treatment of "Gamekeeper's Thumb" by reconstruction of the ulnar collateral ligament

This study examines the treatment of 22 thumbs with symptomatic laxity of the ulnar collateral ligament of the metacarpophalangeal joint by ligament reconstruction 1 week to 10 years after injury. The existing ligament remnants were repaired in 13 thumbs and were re-attached to bone, using a bone anchor, in seven cases. Two ligaments were reconstructed using the extensor pollicis brevis tendon. Patients were reviewed at a mean of 16 months. Functional stability was regained in all patients, but two thumbs had ongoing pain in the metacarpophalangeal joint. All but one patient returned to their original work and recreational pastimes. This study suggests that ligament reconstruction for chronic laxity of the ulnar collateral ligament is likely to achieve painless stability of the metacarpophalangeal joint even when reconstruction is delayed. This makes joint fusion unnecessary in most instances.     

The 'two fleck sign' for an occult Stener lesion

We report a case of distal pull-off of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb with two fracture fragments. The more obvious fracture fragment, seen on plain X-ray to be lying adjacent to the expected location of the attachment of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb, was, in fact, unassociated with it and was part of the attachment of the adductor pollicis muscle. A second smaller fleck of bone which was attached to the displaced collateral ligament was only observed on plain X-ray on retrospective review. This second fleck of bone identified that this was a Stener lesion, requiring surgical reattachment of the ligament. Similar cases in the literature are reviewed and the use of MRI in detecting these lesions is discussed.

Reconstruction of the ulnar collateral ligament of the thumb metacarpophalangeal joint: a cadaver study

PURPOSE: The purpose of this study was to compare the stiffness and strength of the native ulnar collateral ligament with 4 methods of static ulnar collateral ligament (UCL) reconstruction at the thumb metacarpophalangeal (MCP) joint. METHODS: Eleven fresh-frozen cadaver specimens were amputated at the carpometacarpal and interphalangeal joints and all soft tissues were removed except for the extensor pollicis brevis tendon, the proper and accessory collateral ligaments, and the volar plate. Each thumb metacarpal was potted in cement and the native UCL was loaded to failure at 30 degrees of MCP flexion. Ulnar collateral ligament reconstructions as described by Strandell, Osterman, Fairhurst, and a modification of the Glickel procedure then were performed. Each specimen was again loaded to failure and the moment at failure, stiffness, and angle at failure were calculated. RESULTS: None of the reconstructions duplicated the strength or stiffness of the native UCL. The modification of the Glickel procedure with interference knot fixation had a significantly higher moment at failure and was significantly stiffer than any of the other procedures. The differences in strength and stiffness between the Strandell, Osterman, and Fairhurst reconstructions were not statistically significant. There were no significant differences in angle at failure for any of the reconstructions. CONCLUSIONS: No static ligament reconstruction restores the normal stability characteristics of the thumb UCL. The anatomic reconstruction of the UCL with interference knot fixation of the tendon graft has far better strength and stiffness than any of the other reconstructions tested. These characteristics may allow for early motion at the MCP joint.     

Chronic finger joint instability reconstructed with bone-ligament-bone graft from the iliac crest

Five patients with chronic instability of digital joints presented with instability and functional disability. Two patients had ulnar collateral ligament damage of the thumb metacarpophalangeal joint and another had chronic multidirectional instability due to radial collateral ligament, dorsal capsule and palmar plate laxity of the metacarpophalangeal joint of the thumb. The fourth patient had a lax radial collateral ligament and palmar plate of the proximal interphalangeal joint of the little finger and the fifth had chronic laxity of the ulnar collateral ligament of the interphalangeal joint of the thumb. All were reconstructed with bone-ligament-bone graft harvested from the iliac crest. The graft was fixed with screws and joint stability was achieved intra-operatively in all patients. All patients achieved a stable joint with improved functional performance at final follow-up.
