A 6-month-old, 4.1 kg female Dachshund dog presented with intermittent non-weight bearing lameness of the right thoracic limb. Radiographs revealed caudolateral luxation of the right radial head and a shortened right ulna compared to the contralateral limb. Bone lengthening by distraction of the ulna using the Ilizarov technique was performed following ulnar osteotomy. The rate of distraction was 1.5 mm per day, adjusted a total of 3 times daily for a total distraction distance of 10 mm. The Ilizarov fixator was removed four weeks after surgery. The patient showed knuckling due to radial nerve injury that occurred during limb-lengthening. Corrective osteotomy was performed using a plate and pin for the luxation and deformity of the right radial head. The luxation of the radial head was successfully reduced following surgery. However, the knuckling persisted after surgery. Rehabilitation for radial nerve injury was performed using heat therapy, massage, a passive range of motion exercises, water treadmill exercises, neuromuscular electrical stimulation, leash-walking, and acupuncture. 15 months after surgery, the patient showed satisfactory weight-bearing ambulation without recurrence of lameness. The use of the Ilizarov technique is a good surgical option for the treatment of a patient with congenital elbow luxation.

An eight-month old female mixed breed dog was presented to the at Gyeongsang National University Animal Hospital, for tarsocrural arthrodesis. Previously the dog had been presented to a local animal clinic. Orthopedic and blood examinations were conducted. There was absent response of conscious proprioception on the right tarsocrural articulation. The dog stood knuckled onto the digits and had hock dropped but showed normal values in WBC, RBC, Hb, PCV, BUN, creatine, glucose, cholesterol, AST and ALT analyses. The dog was anesthetized and prepared for aseptic surgery. Steinmann pin and Joshi external fixators were applied(bilaterally). 11 weeks after the operation, the external fixators were removed from the bones. The hock dropped was well stabilized, but mild knuckling of distal metatarsopharangeal joint was remained.

Chloramphenicol주사에 의한 좌골신경손상을 유발한 후 Prednisolone을 이용한 약물처치군, 전침군 및 전침과 약물을 병용한 군에서 각각 회복속도를 비교하였다. 정상보행 횟수, pinching을 통한 감각신경의 통감반응,그리고 병리조직소견 등을 죠사한 결과를 요약 하면 다음과 같다. Enrofloxacin, cefazolin, cephalexin, penicillin 등의 좌골신경주위 주사게 서는 신경마비가 관찰되지 않았으나 chloramphenicol을 주사할 경우에는 좌골신경손상으로 인한 편측성 후지마비가 유발되어 knuckling 반응을 보였다. Chloramphenicol을 투여한후 좌골신경손상에 대한 각 처치에서 정상보행 횟수는 8-12주까지는 침술처치군이 약간 중가하 였으나, 처리군간 유의성은 관찰되지 않았다. 실험기간동안 chloramphenicol 에 의한 신경손 상에 대한 각 처치군별 병리조직 소견은 호전양상이 관찰되지 아니하였다.

A male, 11-month-old, Shih-tzu dog weighing 5.2kg showing knuckling secondary to severe cranial bowing of left antebrachium with valgus deformity of the carpus was presented to the Veterinary Medicine Teaching Hospital of Seoul National University. Radiographic findings were a premature closure of the distal ulnar physis, a cranial bowing of the radius, subluxation of the elbow joint, and degenerative changes in the carpal joint. The patient was treated by performing an oblique osteotomy of the radius and ulna, followed by application of External Skeletal Fixations. At 18 weeks postoperatively, the radius was healed. An incongruency of the elbow joint and radial angular deformity was corrected.

The aim of this study is to clarify the therapeutic effect of hemodialysis (HD) on acute renal failure in dogs experimentally induced by ethylene glycol (EG) ingestion in experiment 1(HD on 12 and 36 hours after EG injestion) and experiment 2(HD on 24 and 48 hours after EG injestion). Clinical signs such as vomiting, depression, ataxia and knuckling were improved on experiment 1 and 2. White blood cell (WBC) and platelets (PLT) were decreased, and packed cell volume (PCV) was increased after hemodialysis, however, no significant differences were observed in experiment 1 and 2. BUN, creatinine and phosphorus was significantly decreased in experiment 1 and 2, respectively. These results suggested that hemodialysis was effective for acute renal failure in dogs induced by EG ingestion.

A 2-year-old male, 3 kg body weight Japanese Chin was injured in the automobile accident three months ago. The dog became antebrachiocarpal joint instability, and performed pancarpal arthrodesis using 3 K-wires in localanimal hospital. But, the result was failure. Therefore the dog was referred to Chonbuk Animal Medical Center, Chonbuk National University. In physical examination, right carpal joint instability, knuckling sign and pain were evident. In radiography, sclerosis was observed on the 4th carpal bone. Complete blood count (CBC), serum chemistry and urinalysis finding were within reference ranges. Pancarpal arthrodesis was re-performed using 7-hole plate. However, mild skin and muscle defects was appeared by skin tension of extremity. We expected that granulation would fill the defect, but inflammation was continued on the lesions for 3 days. So, operation which is filling it was done by using the muscle flap and tubed skin flap. The donor muscles were flexor carpi radialis and superficial digital flexor muscles. After 7 days, the muscle flap was survived, but tubed skin flap was necrosed. After 20 days, the skin defect was substituted with granulation tissues. The flexor carpi radialis muscle and superficial digital flexor muscle transposition can be a useful procedure for reconstructing soft tissue defects in the carpal and metacarpal areas.

A 3-year-old castrated male Maltese dog, weighing 4.8 kg was referred with hindlimb ataxia and right forelimb proprioceptive deficits were shown for 20 months. Chiari-like malformation and syringomyelia diagnosed through MRI at a local animal hospital and Knuckling of right forelimb and reluctance to walk were managed with steroid. The medical management was getting ineffective to manage for the symptoms one month before referred. Physical and neurological examinations, radiography, computed tomography, and magnetic resonance imaging were performed and diagnoses of caudal occipital malformation syndrome (COMS) and subsequent syringomyelia (SM) were made. Given that pharmacological treatment was previously ineffective, surgical intervention was recommended. Foramen magnum decompression with duraplasty using $Lyoplant^{(R)}$ was performed. Three days post-surgery, the dog showed improved gait and activity. After 2 months, the dog received no additional prescription medications. At the 12-month follow-up after surgery, the dog showed no clinical problems or recurrences, despite complete cessation of pharmacological treatment. In present report, we applied $Lyoplant^{(R)}$ as a dural graft has been carried out in a dog with COMS. Surgical decompression with $Lyoplant^{(R)}$ was an effective long-term (12-month) treatment for COMS without the need for any pharmacological treatment.
