A 2-year-old, 1.94 kg spayed female Toy Poodle was referred for revision surgery for patellar reluxation following surgery for bilateral medial patellar luxation (MPL). Intermittent non-weight-bearing lameness of the right hindlimb and weight-bearing lameness of the left hindlimb were evident on general inspection. A physical examination revealed that there was a bilateral grade 4 MPL. On radiographs, the medial and lateral trochlear ridge was bilaterally worn out. Patellar groove replacement (PGR) was performed in two stages to replace the bilateral femoral trochlea that had a severely worn out groove. Corrective femoral osteotomy with increasing anteversion angle, tibial tuberosity transposition, medial releasing, lateral imbrications and PGR were performed on the right hindlimb. Six months after surgery on the right hindlimb, a PGR prosthesis was positioned medially on the frontal plane and tibial tuberosity transposition and lateral imbrications were performed on the left hindlimb. Two weeks after surgery, reluxation of the patella occurred on the left hindlimb. The tibial tuberosity transposition was performed to realign the patella more laterally than the previous surgery, and a patellar sling was applied. Two years after the last surgery, the patient showed no pain on the stifle joint and satisfactory weight-bearing ambulation. Reluxation did not recur. PGR maybe a successful treatment for dogs with iatrogenically damaged and/or worn out patellar grooves.

Wii^® balance board (WBB) is a device that can measure and record body sway. This study was conducted to evaluate the reliability of WBB in small sized dog as inexpensive, portable and convenient tool. The center of pressure path length (CPPL) and 95% confidence ellipse area (Area 95) were evaluated with only two plates of WBB. The parameters were evaluated between no load (0 kg) and mass group (0.25-4 kg on each one plate). 23 dogs (2.3-7.3 kg) were evaluated for with hindlimb standing for 10 seconds. The mass group showed a significant value in comparison to the no load during the measurement. And intra-class correlation coefficients (ICCs) between CPPL and Area 95 revealed very high both mass and dog group. In the evaluation of medial patellar luxation (MPL) as a diagnostic tool, 80 dogs with MPL and 23 non-affected dogs were used. In studies of CPPL and Area 95, significant differences were found between non-affected and MPL groups for 10 and 30 seconds, respectively. The WBB can be used as a valid tool for evaluating hind limb standing balance and can be useful as an objective tool to present clinical results in small sized dog with MPL.

Background: Tibial tuberosity transposition (TTT) causes caudalization of the patellar ligament insertion in canine medial patellar luxation, which can lead to increases in patellofemoral contact pressure. Objectives: The purpose of this study is to confirm the effect of patellofemoral contact mechanics after craniolateral and caudolateral transposition of tibial tuberosity in normal canine hindlimbs. Methods: Craniolateral and caudolateral transposition of tibial tuberosity was performed in 5 specimens, respectively. The pressure was measured in the specimen before TTT, and then in the same specimen after TTT. In this process, data was obtained in 10 specimens. The measurement results were output as visualization data through the manufacturer's software and numerical data through spreadsheet. Based on these 2 data and the anatomical structure of the patellofemoral joint (PFJ) surface, whole measurement area was analysed by dividing into medial, lateral and central area. Results: In craniolateralization of tibial tuberosity, total, medial, central contact pressure was decreased and lateral contact pressure was not statistically changed lateral contact pressure than normal PFJ. In caudolateralization of tibial tuberosity, total, lateral contact pressure was increased and medial contact pressure was not statistically changed than normal PFJ. Although not statistically significant changed, central contact pressure in caudolateralization of tibial tuberosity was increased in all 5 specimens. Conclusions: These results imply that traditional TTT, prone to caudal shift of patellar tendon, can increase retropatellar pressure may lead to various complications and diseases of the stifle joint.

A 4 years old male mixed breed dog, which weighed 25.5 kg, referred to Veterinary Teaching Hospital at College of Veterinary Medicine in Chonnam National University, because of chronic hindleg lameness. Click sound by flexion and extension of stifle joint, positive reaction by cranial drawer movement, fat pad sign and tibial position in cranial drawer position on the lateral radiographic view, medial patellar luxation (grade II), and lameness score 2.5 at standing and 2 at walking in right hindleg were showed. Under general anesthesia with enflurane, after medial arthrotomy, it was performed to remove remnants of cranial cruciate ligament and torn medial menisci and joint closed. In modified retinacular imbrication technique, one lateral fabellar/tuberosity suture, one medial fabellar/tuberosity suture, and one imbrication suture adjacent to the patella were placed. At 9 days after operation, lameness score 0 was observed and general condition was excellent.

Recently dental emergency patients tend to increase and diversify because of increased living quality and acknowledgement of health care. We performed this study to understand the pattern of dental emergency and perform the adequate diagnosis and treatment. From August 1998 to July 1999, we inverstigated the rate of dental emergency, distribution according to disease pattern, monthly distribution, and types of emergency treatment from all the emergency patients that visited emergency medicine of Daejin Medical Center, Jesaeng Hospital. There were 266 dental patients(0.978%) from total 27,192 emergency patients. Types of emergency situations included lip lacerations, teeth fracture, teeth missing or avulsion, TMJ contusion, mandible fracture, tongue laceration, toothache, teeth luxation, and so forth. Dental emergency had highest frequency in July. The most common treatments included primary closure of soft tissue lacerations, fixations of luxated teeth and medications.

급격한 치아외상은 치아 경조직에 손상을 주기도 하지만 치수와 치주조직에도 손상을 입힌다. 탈구(luxation)의 경우, 외상에 의해 치근단공 부위에서 신경혈관계의 파괴가 초래되지만 치근파절의 경우에는 파절전 부위에서 이와 유사한 손상이 나타난다. 그러므로 치근파절을 파절선 상부의 치관부에 대한 일종의 탈구로 보기도 한다. 본 증례보고는 외상에 의한 치근파절의 두 가지 치유양상을 비교한 것으로, 한 증례는 특정한 치과적 처치없이 스스로 치유된 경우이고 다른 한 증례는 치아고정 및 근관치료를 포함한 치과치료후에 치유된 경우이다. 수평치근파절의 치유에는 여러 가지 요인이 관여하지만 특히 치아동요도 및 치수생활력이 큰 영향을 미친다. 본 증례에서와 같이 치아의 동요도가 있는 경우에는 고정을 통해서 치유를 촉진하고 치수의 괴사가 초래된 경우에는 근관치료를 포함한 적절한 치과치료를 통해서 치유가 일어날 수 있다. 따라서 치근이 파절된 경우에는 장기간의 관찰을 통해 파절부 치유 및 치수손상 여부를 관찰, 진단하고 그에 따른 적절한 처치를 시행해야 할 것이다.

A 5-year-old, male mixed breed dog was presented to Gyeongsang National University Animal Hospital for bilateral mandibular open fracture by bite. The dog had loss of the teeth and injury of the oral mucosa. Radio-graphic and blood examinations were conducted. Fracture lines were observed between first premolar and second premolar, but temporomandibular luxation was not observed on radiographs. In serum analysis, elevated levels of CPK and LDH were found. The dog was anesthetized and prepared for aseptic surgery. Acrylic external skeletal fixator with Kirschiner wire was applied. Pin loosening and malalignment of the right fracture line was observed at 7 weeks after surgery. We applied Kirschner-Ehmer fixator and half pins during the second surgical procedure. At 4 weeks after a second surgical procedure, the fixator and pins were removed from mandible. The fractures were healed with no complications.

This study was carried out to investigate the characteristics of 335 injured racehorses that had rested over 6 months or were retired in Seoul racecourse from 1994 to 1998. We surveyed 62,117 racing horses and incidence rate of injured horses was 0.54%. Of 335 horses, 322 horses(96.1 %) were associated with musculoskeletal disorders. The musculoskeletal disorders observed with high incidence were fracture and luxation(53.1%), tendinitis and desmitis(17.7%) in category, forelimb(92.5%) in location, below metacarpus/metatarsus(73.0%) in lesion. The prevalence rate of male, 5 years old or Ireland origin was higher than any other individual. These data would be useful standard reference for control of injuries in racing horses.

Patients with diabetes mellitus show delayed wound healing and increased susceptibility to infection. Therefore, the effects of diabetes on pulpal and periodontal healing should be taken into consideration when treating diabetic dental traumatized patients. This case presents the treatment for dental traumatized 20 yr old female with uncontrolled type II diabetes. The traumatized upper central incisors had showed pulpal healing in early days. However, 7 mon after the trauma, the teeth had been diagnosed with pulp necrosis with apical abscess. Eventually, non surgical root canal treatment on the teeth had been performed.
