Combined open bipolar Monteggia and Galeazzi fracture: a case report with a 1-year follow-up.

Monteggia and Galeazzi fractures account for 1-5% of total forearm fractures. A combined Monteggia and Galeazzi fracture is an extremely rare injury. We present a case of a Gustillo-Henderson type 2 open combined bipolar Monteggia and Galeazzi fracture, as well as fracture of the ulnar coronoid process in a 49-year old male.

Peripheral and spinal motor reorganization after nerve injury and repair.

Functional recovery after peripheral nerve injury depends on the amount as well as on the accuracy of reinnervation by regenerative axons. In this study, the rat sciatic nerve was subjected to crush injury or complete transection repaired by either (1) straight nerve suture, (2) crossed nerve suture of tibial and peroneal fascicles, or (3) silicone tubulization leaving a gap of 4 mm. The compound muscle action potentials (CMAP) of gastrocnemius, tibialis anterior and plantar muscles were recorded 90 days post operation to assess functional reinnervation and Fast Blue, Fluoro Gold and DiI were applied to the nerve branches projecting into these muscles to quantify morphological reinnervation.

Elastic stable intramedullary nailing of midclavicular fractures with a titanium nail.

This study presents the results of a minimally invasive operative treatment for markedly displaced midclavicular fractures. In all patients a flexible titanium nail was inserted in an unreamed technique from the sternal end of the clavicle. The result of surgery was determined with clinical and radiographic controls.

Compartment syndrome of the foot.

The hindfoot compartment syndrome occurs in 10% of cases after calcaneal fracture. We analyzed the pathological anatomical reasons for this syndrome using the 10 feet from cadavers plastinated and cut into 4-mm thick sequential sections. CT scans of patients with calcaneal fractures were then compared with the anatomical findings.

Superior muscle reinnervation after autologous nerve graft or poly-L-lactide-epsilon-caprolactone (PLC) tube implantation in comparison to silicone tube repair.

Recovery after peripheral nerve injury depends not only on the amount of reinnervation, but also on its accuracy. The rat sciatic nerve was subjected to an 8 mm long gap lesion repaired either by autograft (AG, n = 6) or tubulization with impermeable silicone tube (SIL, n = 6) or permeable tube of poly-L-lactide-epsilon-caprolactone (PLC, n = 8). Recordings of the compound muscle action potential (CMAP) from gastrocnemius (mGC), tibialis anterior (mTA) and plantar (mPL) muscles were performed 90 days after injury to assess the amount of muscle reinnervation.
