An 11-month-old, 5.6 kg, grade 4 on a 5-point scale body condition score, castrated male Korean short hair cat was presented with right hindlimb lameness for 3 days without trauma. On physical examination, severe pain with crepitation was elicited at the hip region but not at the stifle. Radiographic examination and computed tomography revealed a Salter-Harris type 1 fracture of the femoral capital physis and dysplasia of the proximal tibial epiphysis. Spontaneous femoral capital physeal fracture was suspected and femoral head and neck osteotomy was performed. Treatment for proximal tibial dysplasia was not performed. On histopathologic examination of femoral head, a cluster of chondrocytes in a proliferative zone at the epiphyseal plate was observed. Therefore, spontaneous femoral capital physeal fracture was diagnosed. The patient recovered his gait, and no related clinical signs were observed during 6 months of follow-up.

A 8 months old female dog with the combination of a fracture of the proximal tibia (Salter-Harris type I) with an avulsion of the tibial tuberosity was repaired with cross intramedullary pin for proximal tibial physeal fracture, and intramedullary pin combined with tension band wire for avulsion fracture of tibial tuberosity, resulted in complete healing. At 45 days after operation, on the radiological views, there was premature closure of growth plate of proximal tibia and tibial tuberosity, but at 7 months no developing growing deformities.

An anterior cruciate ligament (ACL) avulsion fracture is an uncommon injury that occurs predominantly in the pediatric and adolescent population. Accurate reduction and fixation of an avulsed fragment are necessary to restore and maintain the length of the ACL and normal knee biomechanics. Several techniques are available to repair an ACL avulsion fracture. On the other hand, treatment is controversial in skeletally immature patients due to risk of physeal injury. This paper reports a case of an ACL avulsed fracture in a skeletally immature patient treated with arthroscopic all-inside suture bridge repair, in which an excellent result and firm stability were obtained without physeal injury.

An 8-month-old, 3.5 kg intact female Toy Poodle was presented for non-weight-bearing lameness on left hindlimb. In radiological testing, left proximal tibal type II Salter-Harris physeal fracture and fibular fracture were seen. Following open reduction, the fracture was stabilized with cross-pins, tension band wires, and a hinged transarticular external skeletal fixator (HTAESF). The range of the HTAESF was increased to $25^{\circ}$ at 7 days postsurgery and to $70^{\circ}$ at 14 days post-surgery. The HTAESF was removed 3 weeks after surgery. At 6 weeks post-surgery, the fracture was successfully healed with no complications and the patient recovered a normal gait. Seven months post-surgery, the patient had a normal gait and a normal stifle joint range of motion compared to the contralateral normal limb. This is a case in which the combined use of cross-pins, tension band wires, and HTAESF was successful for treatment of a proximal tibial physeal fracture in a dog. It is thought that these methods are beneficial for stability of fracture site and recover of joint's normal range of motion through early joint movement.

A one-month-old, male Hanwoo calf was presented to Chonbuk Animal Medical Center with non-weight bearing lameness on its right hindlimb. The radiograph and CT scan showed a Salter-Harris III fracture at the distal tibia. Following open reduction, the fracture was stabilized by cross-pins. A temporal external skeletal fixator was used as an additional support for 5 weeks. 5 weeks after surgery, bone fracture had successfully healed with no complication. At 2 years after surgery, the calf could walk almost normally although intermittent weight-bearing lameness after active exercise. This is a rare case that the combined use of temporal external fixation and cross-pins fixation was sufficiently effective for treating a distal tibial physeal fracture in a calf.

Vitamin D plays a major role in bone metabolism, and its deficiency has an impact on fracture risk and healing. Low vitamin D levels are a cause of poor bone mineralization and have been associated with a significantly higher risk of physeal injury in children. This paper presents a case of a 13-year-old boy with a vitamin D deficiency, who sustained multiple sequential epiphyseal injuries at various areas. This report suggests that vitamin D deficiency is not only a significant cause of the clinical disease itself, but also an important factor affecting the successful recovery of injuries.

Purpose: To evaluate the short-term clinical outcomes of total ankle arthroplasty for the post-traumatic osteoarthritis. Materials and Methods: Fourteen patients who had undergone total ankle arthroplasty from February 2005 to June 2006 were reviewed. Eleven patients were male and three patients were female. The mean age was 52.8 years (range, 33 to 69 years). The mean follow-up duration was 15.9 months (range, 12 to 24 months). Primary injuries were pilon fractures in eight cases, malleolar fractures in three, ankle syndesmotic injury in one, talus fracture and dislocation in one, and distal tibial physeal injury in one. Visual analogue scale (VAS), Range of motion (ROM), American Orthopaedic Foot and Ankle Society (AOFAS) score and complications were evaluated. Results: The mean VAS improved from 8.6 preoperatively to 2.6 at last follow-up. The mean ROM improved from 24.6 degrees preoperatively to 33.1 degrees postoperatively. The mean AOFAS score improved from 44.5 points preoperatively to 75.1 points postoperatively. Radiographically, all components were stable, but there were component malpositions in two cases, including one varus malposition of tibial component and one increased anterior translation of talar component. Complications were deep infection in one case, intraoperative malleolar fracture in three, marginal wound necrosis in two, and heterotopic ossification in one. One prosthesis was revised because of deep infection. Conclusion: Total ankle arthroplasty for the post-traumatic osteoarthritis is believed to be an useful method for preservation of the motion, relief of the pain and high satisfaction of patients in short-term results.
