Hypothenar hammer syndrome. A case report.

Hypothenar hammer syndrome is an uncommon injury of the ulnar artery in its passage through Guyon's canal, and has been associated with repetitive trauma. Its diagnosis requires of a high level of suspicion and a careful clinical interview. The appropriate treatment is not well defined in the literature, ranging widely from medical treatment to reconstructive surgery.

Primary care of nail traumas.

Injuries to the nail complex are common in adults and children. These complex injuries often involve the paraungueal tissues, fingertip and bone. Specialized primary care is essential to limiting the sequelea that are typically difficult to repair secondarily.

[Pedicled joint transfers in the fingers].

Objectives: We report a retrospective series of 27 cases of composite island homodigital distal interphalangeal joint to replace proximal destroyed interphalangeal joint. Results of our series are compared with other procedures available in order to specify the place of pedicled articular transfers mainly for the proximal interphalangeal joint which is recognized as the most important joint in the finger.

Methods: The series included 27 cases of destroyed proximal interphalangeal joints with preservation of the distal interphalangeal joint, the flexor tendon and vascular pedicles.

The preliminary results of treatment of symptomatic carpal boss by wedge joint resection, radial bone grafting and arthrodesis with a shape memory staple.

There is no consensus regarding the aetiology or treatment of carpal boss. Recurrences or carpometacarpal instability is reported after simple resection. Carpometacarpal arthrodesis has been proposed as a primary treatment and after failure of simple resection.

Reconstruction of fingertip defects with the neurovascular tranquilli-leali flap.

For many years, bipedicled palmar advancement flaps were used rarely in fingers because they sacrificed the dorsal branches of the digital arteries, risking dorsal skin necrosis. In 1995, a short bipedicled neurovascular VY advancement flap raised distally to the PIP flexion crease, which spared the dorsal blood supply, was described by Elliot et al. (1995).

[The ulnar longitudinal deficiency: proposition of a descriptive classification].

Ulnar longitudinal deficiency is an extended malformation sometimes involving the whole upper extremity, even including sometimes the opposite side. The clinical and radiological aspects are variable and none of the existing classifications takes into account all the possible deformities. Multiple decisive factors in the surgical indications are missing such as shoulder stability, elbow position (extension or flexion with or without pterygium), orientation of the hand (internal rotation), wrist inclination and number of digits.
