    External skeletal fixation in the management of equine mandibular fractures: 16 cases (1988,1998)

    EQUINE VETERINARY JOURNAL, Issue 2 2001
    K. A. BELSITO
    Summary Fifty-three cases of equine mandibular fractures were managed surgically from 1988,1998, of which 16 (30%) were repaired by external skeletal fixation (ESF). Three surgical methods were utilised: transmandibular 4.76 or 6.35 mm Steinmann pins incorporated into fibreglass casting material or nonsterile dental acrylic (methyl methacrylate - MMA) bars reinforced with steel; transmandibular 9.6 mm self-tapping threaded pins ± 4.76 or 6.35 mm Steinmann pins incorporated into MMA bars reinforced with steel; and 4.5 mm or 5.5 mm ASIF cortical bone screws incorporated into MMA bars reinforced with steel or a ventral MMA splint. Fourteen horses were presented to the hospital for fixator removal at an average of 56.2 days. At removal, fractures were stable and occlusion of incisor and cheek teeth was considered adequate. Complications of the procedure occurred in 3 horses. Two horses with persistent drainage and ring sequestra from pin tracts required curettage 4 or 5 months after ESF removal. A third horse required replacement of the original fibreglass ESF with MMA bars to regain access to open, infected wounds. Another horse required removal of the second premolar at the time of fixator removal because the tooth root had been damaged in the original injury. ESF for the surgical management of mandibular fractures in horses has produced good results, with incisive and cheek tooth alignment reestablished in all horses. Horses that were managed via ESF had a rapid return to full feed and did not require any supplementation via nasogastric tube or oesophagostomy to maintain bodyweight or hydration status. [source]

    Proximal interphalangeal joint instability in the dog

    JOURNAL OF SMALL ANIMAL PRACTICE, Issue 9 2003
    M. J. Guilliard
    A prospective study into the use of transarticular external skeletal fixation in the treatment of proximal interphalangeal instability was undertaken. Only dogs with soft tissue injuries were included. All the dogs except one were greyhounds or related breeds. A hypothesis was proposed that if the articular surfaces were held in normal congruency for a period of time then the development of periarticular fibrosis would alone give sufficient joint support. Joint congruency was maintained by the application of a unilateral external skeletal fixator for approximately three weeks. Complications were common and were due to frame impingement on the neighbouring digit, pin tract infection and pin loosening, and all resolved following frame removal and antibiotic therapy. Careful pinplacement and prophylactic antibiotic treatment prevented complications in subsequent cases. All dogs returned to normal function with no lameness, with the exception of one racing greyhound which had a recurrence of the instability. [source]

    Recent advances in external skeletal fixation

    While the use of external skeletal fixation was once associated with substantial postoperative morbidity, clinical and experimental studies have led to technological advances and modifications in application techniques that have greatly improved the results obtained with this treatment modality. The past decade saw numerous advances in external skeletal fixator implants, components and instrumentation, including improvements in fixation pin design, and the development of new linear external skeletal fixation systems and economical circular external skeletal fixation systems specifically engineered for use in dogs and cats. In addition, a greater understanding of fixator biomechanics and the pathobiology of the bone-fixation pin interface have improved fixator application practices. This article reviews many of the more significant recent advances in external skeletal fixation. [source]

    HS07 TOE TRANSFER , TECHNIQUES & RESULTS

    ANZ JOURNAL OF SURGERY, Issue 2007
    L. C. Teoh
    Toe to thumb-finger transfer requires the understanding of microsurgery and reconstructive technique. The success is measured by the viability of the toe and eventually recreating the function of the original loss. In harvesting of the toe, the big and second toe follows almost the same technique. Identifying the toe artery over the first web space and then dissecting proximally into the intermetatarsal artery is the best approach. To dissect the artery from proximal to distal is often fraught with many dangers. In my cases about 50% the plantar artery is dominant. Anticipation and planning of the artery length is crucial. In toe to thumb transfer the choice can be 2nd toe, total big toe, trimmed big toe or wrap around transfer. In our local populations, 2nd toe is always a good choice. First reconstruction with flap resurfacing may be necessary if the thumb amputation is very proximal. Toe to fingers transfer is usually indicated in 4 finger loss of the hand. In toe to finger transfer I prefer the two 2nd toes transfer into the middle and ring finger position. As the transferred toes can regain less that 50% of motion, the positioning of the toes should be opposable to the thumb. The concept of total reconstruction should be closely followed. Stable skeletal fixation, tendon weave technique, good nerve repair, adequate skin coverage and primary healing are important to ensure good outcome result. [source]

    HS09 REPLANTATION SURGERY , THE RECONSTRUCTIVE APPROACH

    ANZ JOURNAL OF SURGERY, Issue 2007
    L. C. Teoh
    The function of the replanted parts can be improved if attention to reconstruction techniques is carried out. These reconstructive techniques are: 1) adequate debridement and shortening, 2) stable skeletal fixation, 3) strengthened tendon repairs, 4) quality nerve repair, 5) extensive vascular anastomosis, 6) complete skin coverable, and 7) Early intensive active rehabilitation. 1) The debridement should be generous and the shortening judicious. More than 50% of the skin should be in direct contact, and direct anastomosis of some of vessels should be possible. 2) The skeletal stabilization should be of good very quality that will allow free mobilization of the joints. 3) The repair of the tendons should take advantage of the excess length for a strengthen repair. Some degree of active mobilization should be make possible. 4) Primary nerve grafting or nerve transfer should be considered if there is loss of nerve length. 5) Vascular repair should be on the basis of as many as possible the number of arteries and veins that can be found for anastomosis. 6) Any residual skin defect should be planned for a proper resurfacing within the next 5 to 10 days. 7) Early intensive active rehabilitation should be prescribed. Gradual active ROM for tendon gliding should be instituted with in the first week. The function of the replanted digit and hand has continued to improve with the reconstructive approach. With further experience the reconstructive approach can be done in all cases with confidence. [source]
