Scapholunate injuries: challenging existing dogmas in anatomy and surgical techniques.

The management of scapholunate injuries and dissociation remains debatable. Traditional methods of fixation had centred around open procedures, but advances in wrist arthroscopic techniques has redefined both major anatomical findings and operative approaches. This article challenges two main existing dogmas: first, the anatomy of the scapholunate ligament and second, the management of these injuries.

Minimally Invasive Plate Osteosynthesis for a Distal Radius Fracture with Forearm Skin Problem.

In this study, we performed osteosynthesis for a distal radius fracture using a minimally invasive approach for a patient with skin disorder of the forearm and obtained favorable results. This case report may provide new findings confirming the usefulness of this surgical approach for distal radius fractures. Blister formation on the right forearm was observed in a 53-year-old female who was diagnosed with a distal fracture of the right radius and underwent splinting in a local hospital, and she was referred to our hospital 2 days after the injury.

The utility of the fluoroscopic skyline view during volar locking plate fixation of distal radius fractures.

Background Open reduction and internal fixation (ORIF) using a volar locking plate is a common method for treating displaced distal radius fractures. There is, however, the risk of extensor tendon rupture due to protrusion of the screw tips past the dorsal cortex, which cannot always be adequately seen on a lateral fluoroscopic view. We therefore wished to compare the sensitivity of an intraoperative fluoroscopic skyline view to a lateral fluorosocopic view in detecting past pointing of these screws.

Fifth carpometacarpal fracture dislocations fixed with Meta-HUS®: a series of 31 cases.

Fracture dislocations of the fifth carpometacarpal are usually treated by percutaneous K-wires despite occasional complications: displacement, stiffness, malunions, and arthritis. Our aims were to evaluate the use of locked K-wire fixation for these fracture dislocations. Our series includes 31 fracture dislocations, five extra-articular and 26 articular, 21 of which were at the base of the metacarpal, four at the hamate, and one involving both the hamate and the metacarpal.

Arthroscopic assisted percutaneous screw fixation of Bennett's fracture.

Several techniques are used for fixation of Bennett's fractures. The aim of this study was to assess a technique of arthroscopic-assisted reduction and percutaneous cannulated screw fixation of Bennett's fractures. Seven patients (mean age 29 years) with three fractures Type I and four fractures Type II according to Gedda were operated under arthroscopic lavage, fluoroscopic screw fixation, and arthroscopic control of the joint reduction.

Vascularized nail transfer from non-replantable digit: a case report.

We report the case of a traumatic amputation by circular saw of the ring and small fingers, associated with middle finger nail matrix loss and tendon, bone and joint exposure. The replantation was not attempted with patient's consent. Since the nail unit from the ring finger was intact, we decided to harvest the ring finger nail unit for major finger reconstruction.

Percutaneous fixation of first metacarpal base fractures using locked K-wires: a series of 14 cases.

The treatment of choice for first metacarpal base fractures is surgical. Open fixation is stable but causes tendinous adhesions. Percutaneous fixation is minimally invasive but is often followed by secondary displacement.

Hamate hook nonunion treated with a hook plate: case report and surgical technique.

Despite of its rarity, hamate hook nonunion can cause several complications like tendon rupture or loss of grip strength. Admitted treatments in the literature are excision of the bone fragment or its open reduction and internal fixation. We report a clinical case of a high-level baseball player with hamate hook nonunion treated with an original technique of fixation using a hook plate.

Limb replantation with two robots: a feasibility study in a pig model.

The aim of this study is to assess the feasibility of limb replantations and transplantations by telesurgery. The material consisted in a large white pig and two surgical robots (DaVinciS telemanipulators). The procedure consisted in a trans-humeral cross-section of the left thoracic limb, which was secondarily replanted.

Nerve repair in telemicrosurgery: an experimental study.

Since the development of microsurgery in the 1960s, the prognosis of peripheral nerve lesions has greatly improved. However this new technique's evolution has remained limited by human factors, in particular by physiological tremor. Telesurgery, a technique used in other surgical fields, was developed in the 1990s.
