小夹板外固定术在野生动物骨折治疗中的应用

动物园中野生动物由于季节发情、领地或者群体地位争夺等原因,时常出现打架、碰撞而造成骨折现象。这种骨折多为单纯长骨性骨折,骨折情况并不复杂。因此,根据野生动物恢复力强等特性,对于这种情况多采用中国传统中医治疗骨折手法,通过手法复位、小夹板固定、中药治疗,更倾向于无创治疗,最大限度地保护骨折端软组织,促进骨折快速愈合,恢复功能。     

Surgical Repair of a Comminuted Distal Femoral Fracture in a Dog

This case illustrates that good results may be achieved with fractured femur that was severely comminuted (i.e. a "Humpty Dumpty" fracture). The blood supply at the fracture site must be carefully preserved. The bony architecture must be reestablished with perfect reduction of the articular surfaces, preferably with interfragmentary compression between the bone fragments. These fragments are held in place with screws and Kirschner wires. Some of the screws and pins were left in place as the trauma incurred to retrieve them would have done more harm than good due to bony overgrowth.     

Multiple Rib Fracture Repair in a Neonatal Holstein Calf

Objectives— To report rib fracture repair in a neonatal calf using the Securos^® Cranial Cruciate Ligament Repair System (SCCLRS).
Study Design— Case report.
Animals— A 2-day-old female Holstein calf with fracture of right ribs 4–10.
Methods— On the day of admission the calf was anesthetized and rib fractures were repaired using open reduction and the SCCLRS.
Results— Rib fractures were successfully stabilized and the calf discharged from the hospital 8 days postoperatively.
Conclusions— Modification of previously reported use of the SCCLRS to repair rib fractures in foals was required because of the different anatomy in the calf. This new technique was rapidly and easily performed for a large number of fractured ribs in this case.
Clinical Relevance— Effective rib fracture repair in calves can be readily performed using the SCCLRS with modification of the technique reported in foals.     

Repair of an Ulnar Fracture With Radial Luxation in a Horse

An ulnar fracture with radial luxation (Monteggia fracture) was repaired in a horse. Reduction of the radial luxation was difficult, requiring 2 incisions, limb traction, neuromuscular blockade, and direct radial manipulation. The ulnar fracture was repaired by use of a dynamic compression plate. Three months postoperatively, the horse was free of any apparent lameness.     

Cranial Approach to the Humerus for Repair of Fractures in Horses and Cattle

A cranial approach to the humerus was developed for application of a compression plate for repair of comminuted humeral fractures in a weanling foal, a calf, a heifer, and a mature cow. An incision was made from the cranial portion of the greater tubercle of the humerus to the radius. The cranial aspect of the humerus was exposed by retraction of the brachiocephalicus muscle and blunt dissection between the biceps brachii and brachialis muscles. A second plate was applied laterally in the heifer and cow by retraction of the brachialis muscle and elevation of the extensor carpi radialis muscle. Successful fracture reduction, alignment, and stabilization were achieved in all four animals.     

Proximal Radius Fracture in a Horse: Angle Blade Plate Repair

The repair of a comminuted fracture of the proximal radius in a 300-kg horse was achieved using an angle blade plate and a dynamic compression plate. Placement of an angle blade plate required adequate preoperative preparation to ensure successful use and to avoid joint damage. The horse has been returned to atheletic performance and has remained sound.     

Surgical Repair of a Pelvic Fracture in a Ferret (Mustela putorius furo)

A 9-month-old, chemically spayed female ferret (Mustela putorius furo) presented after a fall (5.5 m) from the first floor of an apartment building. The animal was nonambulatory, with pain localized in the pelvic region. Radiographic examination revealed a bilateral fracture of the iliac body with medial displacement of the left hemipelvis and narrowing of the pelvic canal. Rib fractures, pulmonary contusions, and pleural effusion were also present on thoracic radiographic images. After emergency stabilization of the patient, the fracture of the left iliac body was successfully repaired using a composite internal fixation system with K-wires and polymethylmethacrylate. The implants allowed fracture healing despite loosening of one of the K-wires. Bony healing was achieved within 25 days, including the restoration of pelvic rigidity and maintenance of the diameter of the pelvic canal. Orthopedic examination was unremarkable 4 months following the surgical procedure. To the authors’ knowledge, this is the first described open reduction of a pelvic fracture in a ferret.
