Tarsometatarsal subluxation in dogs: partial arthrodesis by plate fixation     

Muir P  Norris JL 《Journal of the American Animal Hospital Association》1999,35(2):155-162

In a retrospective study of tarsometatarsal joint subluxation in eight dogs, secondary fractures were identified in six dogs, particularly of the fourth tarsal bone and the proximal fifth metatarsal bone. Common causes of tarsometatarsal joint injury included jumping or falling and direct trauma to the foot. Partial tarsal arthrodesis, with the use of bone-plate stabilization and cancellous bone grafting of joint spaces after removal of articular cartilage, led to progressive bone healing in all dogs. Implant breakage did not occur in any dog.  相似文献   

Arthrodesis of the Distal Intertarsal and Tarsometatarsal Joints in the Horse     

SPENCER M. BARBER DVM 《Veterinary surgery : VS》1984,13(4):227-235

Arthrodesis created by destruction of the articular surfaces of the distal intertarsal and tarsometatarsal joints by repeated insertion of a drill was studied in one limb of each of nine horses. Postoperatively, the horses were housed in box stalls for 8 weeks and then confined to a paddock for 19 weeks. Clinical and radiographic evaluations were performed prior to surgery, immediately following surgery, and at 2,4, 6, 8,10,12,16, 20, and 27 weeks following surgery. There was a statistically significant positive correlation between decreasing degree of lameness and increasing radiographic evidence of bony fusion; fusion of the distal intertarsal and tarsometatarsal joints was present in five horses 27 weeks after surgery. The horses lost weight during the first 8 weeks after surgery. Flexion of the treated tarsal joints was decreased significantly at the end of the experiment.
Complications encountered included fracture of the third tarsal bone (five horses), instability of the tarsus (four horses), septic arthritis (three horses), and diarrhea (four horses).
Arthrodesis, with this method of surgical drilling of the distal intertarsal and tarsometatarsal joints, is not recommended because of severe pain, prolonged convalescence, and high incidence of complications.  相似文献   

Arthrographic Analysis of Communication between the Tarsometatarsal and Distal Intertarsal Joints of the Horse     

ANN E. KRAUS-HANSEN DVM    HENRY W. JANN DVM  MS  Dipiomate ACVS    DAVID V. KERR DVM  GUSTAVE E. FACKELMAN DVM  DMedVet  Dipiomate ACVS 《Veterinary surgery : VS》1992,21(2):139-144

The intra-articular anatomy of 103 equine tarsi was studied by contrast radiography with image intensification and computerized tomography. There was communication between the tarsometatarsal and distal intertarsal joints in 21 of 55 (38%) interpretable tarsometatarsal arthrograms, and in 11 of 48 (23%) interpretable distal intertarsal arthrograms. The difference was not significant. The volume of contrast agent and the pressure of injection did not correlate with communication. Forced injection caused subcutaneous leakage of contrast medium but not communication. Communication occurred via the tarsal canal and the space between the third and the combined first and second tarsal bones. Injection of the distal intertarsal joint from the dorsomedial aspect of the limb, distal to the palpable distal border of the medial branch of the tendon of the tibialis cranialis muscle and between the central, third, and combined first and second tarsal bones, provided reliable access except in the presence of severe periosteal proliferations.  相似文献   

In Vivo Investigation of Communication Between the Distal Intertarsal and Tarsometatarsal Joints in Horses and Ponies

The frequency of communication between the tarsometatarsal and distal intertarsal joints was investigated in 27 horses and 12 ponies. After the injection of diluted latex into the tarsometatarsal joints using the plantarolateral approach, the horses and ponies were walked for 200 meters. Latex was found in the distal intertarsal joints of 19 of 73 tarsi (26% communication) at necropsy. In 3 tarsi, latex was also found in the proximal intertarsal and tar-socrural joints.  相似文献
