BACKGROUND Intramedullary fixation with use of a telescopic rod with a T-piece is one of the standard methods for long-bone stabilization in growing children with osteogenesis imperfecta. However, installation and removal of this device can cause substantial damage to the distal joint, which limits its use, especially in the tibia. We devised a modification of the telescopic rod system--the int...

Background: Pantarsal arthrodesis is a salvage procedure carried out for the treatment of tarsal joint disease, including severe osteoarthritis with intractable pain in tarsocrural joint, fractures, shearing injuries, instability, and failure common calcaneal tendon. Although medial plating preferable, high incidence post-surgery complications possible. Using thin, pre-contouring or easy contou...

The humeri of eleven feline cadavers were dissected and safe anatomical areas for placing external skeletal fixator pins were determined. Relevant measurements taken of the humeral condyle enabled a determination of a safe pin diameter range of 1.5 to 2.2 mm for transcondylar pins. Further anatomical measurements allowed recommendations to be made to angle pins in the distal humerus in a distol...

This study investigated the outcomes of extra-articular distal radius fractures and simple intra-articular radial styloid fractures stabilized with a novel threaded cannulated device. This was a retrospective study of 24 distal radius fractures treated with the T-Pin device (Union Surgical LLC, Philadelphia, Pennsylvania), with a minimum of 1 year of postoperative follow-up. Outcome data includ...

BACKGROUND The optimal management of femoral fractures in adolescents is controversial. This study was performed to compare the results and complications of four methods of fixation and to determine the factors related to those complications. METHODS We conducted a retrospective cohort study of 194 diaphyseal femoral fractures in 189 children and adolescents treated with elastic stable intram...

abstract background: distal radial fracture is one of the most common fractures of the skeletal system. although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. the goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extra...

A 3-year-old wild gray wolf was referred to the Department of Veterinary Clinical Sciences of ShirazUniversity with a history of car accident. The radiographic examination showed supracondylar distal femoralfracture in right leg. The wolf was pre-medicated by acepromazine followed by induction of anesthesia usinga combination of diazepam and ketamine. Anesthesia was maintained by halothane. The...

Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here, we clarify the origin of wetting hysteresis for a liquid front advancing or receding across an isolated defect of nanometric size. Various kinds of chemical and topographical nanodefects, which represent salient features of actual heterogeneous surfaces, are investigated. The most pr...
