Objective: To report the use of tarsometatarsal intramedullary pin stabilization for arthrodesis of the tarsometatarsal joint.
Study Design: Case series.
Animals: Dogs (n = 12) and cats (n = 2) with tarsometatarsal instability.
Methods: Medical records (January 2004-February 2011) were reviewed for dogs and cats with tarsometatarsal instability repaired with intramedullary pin stabilization. After a dorsal approach to the tarsometatarsal joint, the articular surface was removed, and intramedullary pins were inserted through the metatarsal bones into the distal tarsal bones. Stabilization was supplemented with external coaptation until healing occurred. The intramedullary pins were removed after radiographic evidence of arthrodesis.
Results: Radiographic evidence of bony fusion across the tarsometatarsal joint occurred in all animals. One major complication occurred, with skin necrosis at a single pin site requiring surgical debridement at the pin site. Follow-up (mean, 107 weeks) was available for 13 cases; 12 were reported to be completely sound, and 1 dog was ambulating normally at a walk but favored the leg when running.
Conclusion: Tarsometatarsal intramedullary pin stabilization can be used for the treatment of tarsometatarsal instability with a low risk of major complications.

Surgical intervention in preschoolers with femoral shaft fractures has increased due to the evolving lifestyle. This study aimed to analyze and compare the efficacy of elastic intramedullary nailing and external fixation in treating femoral shaft fractures in children aged 2-5. Ninety-nine pediatric patients were categorized into the external fixator (EF) and the elastic intramedullary nail (ESIN) group based on surgical techniques.

Objective: To assess the biomechanical parameters of intact tibiotarsi (INT) and tibiotarsi with a 5-mm segmental diaphyseal defect repaired using four osteosynthesis techniques: a locking plate (LP), a plate-rod combination, an external skeletal fixator (one end-threaded positive-profile pin per fragment) with an intramedullary pin tie-in (TIF 1), and an external skeletal fixator (two end-threaded positive-profile pins per fragment) with an intramedullary pin tie-in (TIF 2).
Study Design: Sixty tibiotarsi from 30 adult laying hens were allocated into five groups for nondestructive dynamic torsion and four-point bending tests, followed by failure tests. Nondestructive dynamic tests evaluated stiffness over time in torsion and bending.

Background: Radial neck fractures account for 1% of all pediatric fractures and 5% to 10% of pediatric elbow fractures. The mechanism of injury is typically a fall with the elbow in hyperextension and the forearm in supination. A valgus force compresses the radial head against the capitellum, causing a radial neck fracture.

Four adult female patients were treated with an intramedullary Steinmann pin for an unstable extra-articular distal ulnar fracture associated with a distal radial fracture treated with plate osteosynthesis. All showed good radiographic and functional outcomes. One patient required removal of the Steinmann pin.

Background: To investigate the effects of remimazolam and surgery on cognitive function and neuropathology.
Methods: We performed intramedullary pin fixation of tibial fractures in wild-type male (12-13-week-old) C57BL/6J mice under intraperitoneal anesthesia with remimazolam. Age-matched wild-type control mice received either saline or remimazolam without surgery.
