CASE: We report a case of a rare "floating fibula" ankle injury characterized by dislocation of the proximal tibiofibular joint (PTFJ), syndesmosis disruption, complete deltoid disruption, and tibiotalar dislocation without fibula fracture in a 44-year-old man. Imaging includes preoperative and postoperative radiographs and CT scans. Treatment involved reduction and screw fixation of the syndesmosis and PTFJ with planned screw removal. A successful clinical and radiographic outcome was achieved at the 15-month follow-up...

Current literature is limited with respect to the proximal tibiofibular joint (PTFJ) and clinical conditions relating to the PTFJ. Diagnosis and treatment of conditions that affect the PTFJ are not well described and are a topic of debate among many physicians. This manuscript aims to review and summarize the most recent literature that relates to traumatic dislocations, fractures, chronic instability, and osteoarthritis, with a focus on both diagnostic and treatment strategies of these conditions. We also review PTFJ anatomy, biomechanics, and the clinical presentation of some common PTFJ conditions...

For AO 44-B2 ankle fractures of uncertain stability, the current diagnostic standard is to obtain a gravity stress radiograph, but some have advocated for the use of weight-bearing radiographs. The primary aim was to compare measures of medial clear space (MCS) on weight-bearing cone beam computed tomography (CBCT) scans versus gravity stress radiographs for determining the state of stability of ankle fractures classified as AO SER 44-B2 or Weber B. The secondary aim was to evaluate the details offered by CBCT scans with respect to other findings that may be relevant to patient care...

PURPOSE: We determined whether naturally-occurring lenticular myopia in English Springer spaniels (ESS) has a genetic component. METHODS: Streak retinoscopy was performed on 226 related ESS 30 minutes after the onset of pharmacologic mydriasis and cycloplegia. A pedigree was constructed to determine relationships between affected offspring and parents. Estimation of heritability was done in a Bayesian analysis (facilitated by the MCMCglmm package of R) of refractive error in a model, including terms for sex and coat color...

Donor site morbidity and complication rate using the reamer-irrigator-aspirator (RIA) system for intramedullary, non-structural autogenous bone graft harvesting were investigated in a retrospective chart and radiographic review at a University affiliated Level-1 Trauma Centre. 204 RIA procedures in 184 patients were performed between 1/1/2007 and 12/31/2010. RIA-indication was bone graft harvesting in 201 (98.5%), and intramedullary irrigation and debridement in 3 (1.5%) cases. Donor sites were: femur - antegrade 175, retrograde 4, tibia - antegrade 7, retrograde 18...

Tibial plateau fractures are complex injuries that can affect both knee function and stability. In the past, surgeons have relied on radiographs, viewboxes, tracing paper, and scaled acetate templates to formulate a preoperative plan. With the advent of digital radiography, viewboxes, and standard radiographs are no longer routinely available. The availability of a digital format for preoperative planning has helped to address this, but fragment manipulation and implant templating are not features of most digital radiography systems...

BACKGROUND: Diaphyseal and distal femoral fractures are painful injuries that are frequently seen in patients requiring a trauma work-up in the hospital emergency department prior to definitive management. The purpose of this study was to determine whether a femoral nerve block administered in the emergency department could provide better pain relief for patients with femoral fractures than currently used pain management practices. METHODS: Patients who presented with an acute diaphyseal or distal femoral fracture were identified as potential candidates for this study...

OBJECTIVE: To assess the refractive state of eyes in various breeds of dogs to identify breeds susceptible to ametropias. ANIMALS: 1,440 dogs representing 90 breeds. PROCEDURES: In each dog, 1 drop of 1% cyclopentolate or 1% tropicamide was applied to each eye, and a Canine Eye Registration Foundation examination was performed. Approximately 30 minutes after drops were administered, the refractive state of each eye was assessed via streak retinoscopy...
