一例犬桡尺骨骨折内固定的病例报告

正骨折是指骨结构的连续性完全或部分断裂。有研究表明,桡尺和尺骨骨折占犬、猫骨折总数的8.5%～18%~([1])。临床上90%以上的病例都是桡骨和尺骨同时骨折,以横骨折和斜骨折多发[2]。临床上治疗多以骨板内固定为主,在大型犬需要对桡骨和尺骨分别进行固定,在小型犬只需要固定桡骨,但小型犬远端桡骨的血供比大型犬少,骨远端周围的软组织也较少,如果植入物选择不当或者操作过程中对软组织损伤严重,容易造成骨不愈合或愈合延迟。笔者在临床上多次使用骨板内

Multiple Intramedullary Wire Fixation of a Radial Fracture in a Dog

Multiple intramedullary wire fixation infrequently can be used as an alternative technique to plating, transfixation devices, single intramedullary pinning, or external coaptation for some radius and ulna fractures.
This report describes a comminuted fracture of the radius and ulna with fissures and comminution extending too far into the proximal radius for effective application of a bone plate or Kirschner-Ehmer apparatus. Resulting fracture instability and collapse prohibited effective use of external coaptation as a primary means of fixation. The radial fracture was repaired and stabilized with full cerclage wires and multiple intramedullary Kirschner wires. The dog was using the leg normally 12 months following surgery.     

Fractures of the radius and ulna.

Fractures of the radius and ulna are common in the dog and cat. If treated inappropriately, complications may result. These include delayed union, nonunion, malunion, and growth deformities. ESF is a versatile method of fixation for fractures of the radius and ulna. Types that are applicable range from the simple type I to the complex type III fixator. In general, the more unstable the fracture, the more rigid the assembly must be to counteract fracture forces. There are three basic phases to consider when using ESF: (1) preoperative planning, (2) application of the ESF, and (3) long-term management. A deficiency in any one of these phases can lead to complications and an unsatisfactory clinical outcome. Although ESF can be used on many types of fractures, the technique is especially well suited for open or highly comminuted fractures when internal fixation is not applicable. In these cases, close attention must be paid to the integrity of the soft tissues. In addition, cancellous bone grafts should be placed either at the time of initial repair or in a delayed fashion after adequate vascularity has been established. Staged or complete removal of the ESF should be individualized to each fracture case. In general, staged disassembly or "dynamization" can begin when the bone and fixator begin to function as a composite as determined by radiographs. Complete fixator removal should be considered when the fracture exhibits clinical and radiographic evidences of union.     

Repair of fracture of the proximal portion of the radius and ulna in a llama

Repair of a comminuted fracture of the proximal portion of the radius and ulna in a 4-month-old llama was achieved by use of internal fixation. An 8-hole narrow dynamic compression plate was applied to the lateral aspect of the radius and a 7-hole narrow dynamic compression plate was applied to the cranial aspect of the radius. One year after surgery, the llama had a normal gait and the cosmetic appearance of the limb was excellent.     

Treatment of fractures in avian species.

External fixation, with coaptation or Kirschner-Ehmer splints, is a viable treatment for many fractures in captive and wild birds. Important considerations in selecting a device are the weight and size of the device, location of the fracture relative to joints, and prognosis associated with location of the fracture(s). A variety of materials, not limited to traditional medical materials, may be used in coaptation splinting. Straws, plastic spoons, and rubber balls can serve as effective splints. Type I and II Kirschner splints are typically used in birds, although large birds may require a type III splint on leg fractures. The most useful configuration for wing fractures is the type Ia single bar splint using epoxy or acrylic for the connecting bar. This splint is lightweight, positioned close to the patient, and stable for most fractures. The type II splint is an excellent choice for leg fractures at the level of the tibiotarsus and below. The destructive character of psittacines requires all splints be protected from the beak of the bird. Clavicular-furcular and coracoid fractures in small birds may be effectively managed with coaptation splinting. In birds over 400 g body weight, open reduction is needed for best results. Since fractures of the foramen triosseum are usually not surgically repairable, they can be stabilized with coaptation splints. Although humeral fractures may be managed with coaptation in some circumstances, firm stabilization with a type I Kirschner-Ehmer splint or internal fixation is best. Single bone fracture(s) of the radius or ulna can usually be managed with minimal treatment, brailling, or figure-of-eight wraps. Fractures of both the radius and the ulna require a type I Kirschner-Ehmer splint for internal fixation. Coaptation splinting alone is usually indicated for carpal or carpometacarpal injuries. Femoral fractures in small birds may be managed with coaptation splinting, although fractures in large birds or unstable fractures require internal fixation or a type I Kirschner-Ehmer splint. Tibiotarsal fractures, in many species, may be managed with internal fixation or a type II Kirschner-Ehmer splint. Tarsometatarsal fractures can be cast or stabilized with a type II Kirschner-Ehmer splint. Phalangeal fractures are best managed with coaptation splinting.     

Large segmental radius and ulna defect treated by bone transportation with the Ilizarov technique

An 8-year-old male Boxer with a severely contaminated open fracture of the left radius and ulna fracture, produced by a helicopter propeller, was treated using bone transport by the Ilizarov method. Extensive diaphyseal bone loss and soft-tissue vascular damage were present. The radius and ulna were stabilised with an Ilizarov ring external fixator. The bone defect was partially shortened and restored by gradual transport of a bone segment created from proximal segments of the radius and ulna. The external fixator was removed 4 fi months after the beginning of the latency period, due to instability caused by osteolysis around the wires. A cast was placed for 3 weeks. Although the bone transport had resulted in formation of approximately 4 cm of bone, the antebrachium showed approximately 50% shortening when compared to the contralateral limb. The infection was eradicated, and the dog was able to bear weight on the operated limb when walking.     

Biomechanical analysis of 3 fixation techniques in rabbit radius and humerus bones

The objective of this study was to compare the strength and stiffness of various fixation methods applied to the long bones of the rabbit forelimb. Twenty rabbit radius/ulna and 20 rabbit humeri were randomly assigned to 1 of 4 groups. Control bones remained intact, whereas all others were osteotomized to create fracture models that were fixated with locking plate and locking screws (LP), veterinary cuttable plate (VCP) with cortical screws, or external skeletal fixator constructs (ESF), and tested in 4-point bending until failure. Load/deformation curves were generated for each sample and used to calculate stiffness (slope of the curve) and strength (load to failure). Intact controls had greater strength and stiffness than any fixation techniques in the rabbit radius/ulna and humeri samples. Locking plate and VCP constructs had greater stiffness than ESF when applied to the radius, whereas locking plate constructs were stronger than VCP or ESF when applied to the humerus. Overall, the LP construct had characteristics most closely resembling those of the intact control regarding strength in the humerus. Therefore, fracture fixation with a LP would provide the greatest strength in humeral fracture repairs in the rabbit.     

Management of antebrachial deformity and shortening secondary to a synostosis in a dog

A nine-week-old labrador was presented with a deformed left forelimb causing obvious lameness. Radiographs suggested that the dog had suffered a fracture involving the radius and ulna which had healed resulting in a synostosis. There was a concurrent radial physeal injury. The dog was treated initially by osteotomy of the radius and ulna stabilised using a static external skeletal fixator. At a subsequent surgery lengthening of the limb was achieved by using an Ilizarov apparatus. Worsening carpal hyperflexion was managed by bandaging in forced extension. A successful outcome was achieved with a final result of a 24 per cent discrepancy in length between the two radii at 17 months of age. An increase in length of the ipsilateral humerus was seen in association with the shortened forelimb.     

A survey of bone fractures in the dog and cat

A survey was made of 284 canine and 298 feline fractures admitted to a metropolitan small animal hospital over a 2-year period. Approximately 80% of fractures occurred in animals less than 3-years old. Males were more commonly involved than females in both species. Road accidents were the main cause of fracture but falls and crush injuries were more common in dogs than cats. Bones most commonly affected in the cat were femur (28·2%), pelvis (24·8%) and mandible (11·4%), and in the dog radius and ulna (17·3%), pelvis (15·8%), femur (14·8), and tibia (14·8%). Forty percent of fractures were treated conservatively or by external fixation, 46·8% by internal fixation, and 13-1% were not treated. Results were satisfactory in 96·7% of treated cases.
