PRACTICAL RELEVANCE: Maxillofacial and traumatic dentoalveolar injuries can cause pain and inflammation, and reduce function of the mouth, impacting a cat's quality of life. Many traumatically induced feline fractures have been reported to involve the mandible or skull and, in cats with maxillofacial trauma, traumatic dentoalveolar injuries are particularly prevalent. Traumatic dentoalveolar injuries can also often be found in otherwise healthy cats.
Fracture Fixation and Implants
A 4 · 5-month-old, 13 · 8 kg, female neutered mixed breed dog was presented for evaluation of acute non-weight bearing right pelvic limb lameness. Radiographs revealed a tibial tuberosity avulsion fracture for which open reduction/internal fixation was performed. Asymmetrical premature closure of the cranial aspect of the proximal tibial physis ensued with a tibial plateau angle of -12°. Abnormal stifle biomechanics resulted in lameness and caudal cruciate ligament fraying.
A two-year-old Rottweiler presented for acute onset of a right hindlimb lameness 20 weeks after a cementless total hip replacement (THR) and 16 weeks after open reduction to address luxation of the THR. Radiographs revealed periosteal proliferation of the medial acetabulum and a stable implant. Synovial fluid cytology was consistent with inflammatory joint fluid. Treatment consisted of surgical debridement and intravenous and oral antibiotics. THR implants were not removed. Culture of tissue removed from the THR site yielded growth of Pseudomonas and Staphylococcus species.
To document the results of management of feline distal tibial fractures with circular-linear hybrid external skeletal fixators.
Retrospective examination of case records and radiographs of cats with distal tibial fractures managed with hybrid external skeletal fixators. Signalment, pre-operative fracture conformation, post-operative fracture reduction, implant complications, time to tibial and fibular fracture healing and time to hybrid external skeletal fixators removal were analysed.
The aim of this study was to report the outcome of acute antebrachial angular and rotational limb deformity (AARLD) correction using a standard radial ostectomy, an unarticulated type 1b external skeletal fixator (ESF) and intra-operative alignment with no pre-operative planning.
This report describes the successful management of a carpal hyperextension injury in a cat using combined temporary transarticular internal and external skeletal fixation, without performing an arthrodesis. To our knowledge, there have been no previous reports of management of feline carpal hyperextension injuries in this fashion.
Objective-To evaluate the proportion of and risk factors for open fractures of the appendicular skeleton in dogs and cats that were a result of acute trauma. Design-Cross-sectional and case-control study. Animals-84,629 dogs and 26,675 cats. Procedures-Dogs and cats examined at Purdue University Veterinary Teaching Hospital from January 1993 through February 2013 were identified; the proportion of open fractures was estimated from the medical records.
To evaluate the incidence and risk factors for occurrence of osteosarcoma (OSA) following tibial plateau levelling osteotomy (TPLO).
A four-year old male Labrador Retriever was admitted with head trauma after being hit by a car. The dog had sustained multiple nasal, maxillary, and frontal bone fractures that resulted in separation of the maxilla from the base of the skull. A severely comminuted left zygomatic arch fracture was also present. These fractures were all repaired using a point contact, locking titanium plate system, in a single procedure that resulted in excellent postoperative occlusion and immediate function. Healing was uneventful.
To compare the biomechanical properties of clamp rod internal fixation (CRIF)/rod and LC-DCP/rod constructs in a canine femoral gap model.
