This retrospective study is designed to compare the clinical results of tibial tuberosity transposition (TTT) and anti-rotation suture (ARS) treatments for medial patellar luxation (MPL). Medical records of 133 dogs were reviewed that had undergone surgical correction of MPL between January 2013 and May 2017. MPL correction was performed on 182 stifles, with TTT and ARS being performed on 101 stifles and 81 stifles. The common dog breeds receiving surgical treatment for MPL were Maltese, Pomeranian, Chihuahua and Poodle. Mean age of dogs with MPL was 32.6 months, and their mean body weight was 4.26 kg. Seventy dogs (52.6%) were male and 63 (47.4%) were female. Of the 182 stifles with MPL, grade II, III and IV were 18.7%, 72.0% and 9.3%. Total complications after TTT and ARS were recorded in 16.8% and 29.6%. Major complications after TTT and ARS were recorded in 5.9% and 12.3%, minor complications after TTT and ARS were recorded in 10.9% and 17.3%. The risk of complication and reluxation rate after TTT were significantly lower than that for ARS (p < 0.05). However, the rate of reluxation among dogs treated by ARS (1.2%) for grade II MPL was significantly lower than that for dogs treated by ARS (8.6%) for grade III MPL (p < 0.05). The TTT group had a shorter recovery period after surgical intervention than that in the ARS group (p < 0.001). In conclusion, TTT had a significantly lower incidence of complication and a shorter recovery period than ARS. However, ARS for grade II MPL appears to be a good surgical option for reducing the rate of reluxation after surgery. These results of this study could be used to provide therapeutic guidelines for surgical MPL correction in small-breed dogs.

Background: Minimally invasive surgery (MIS) technique of sacroiliac luxation in toy breed dogs using cannulated screws has not been described. Objectives: The purpose of this study was to evaluate the effectiveness of pelvic canal recovery, the reproducibility of successful surgery outcomes, and the acceptable difficulty of the procedure in MIS of sacroiliac luxation in toy breed dogs. Methods: MIS using 2.3-mm cannulated screws was demonstrated in 12 toy breed dog cadavers with sacroiliac luxation artificially induced. Pre and postoperative radiographs were used to evaluate the pelvic canal diameter ratio (PCDR), hemipelvic canal width ratio (HCWR), and reduction rate. Dorsoventral angle (DVA) and craniocaudal angle (CCA) of the inserted screw were obtained postoperative computed tomographic scan. Results: The statistically significant difference between the mean pre and postoperative PCDR was found (1.10 ± 0.12 and 1.26 ± 0.11, respectively; p = 0.002), and the mean HCWR close to 1.0 meaning symmetric pelvis also was obtained (0.97 ± 0.07). The mean DVA and CCA were 2.26° ± 1.33° and 2.60° ± 1.86°, respectively. Conclusions: MIS of sacroiliac luxation using 2.3-mm cannulated screws is applicable to toy breed dogs with acceptable difficulty.

In dentistry, elevator instruments are used to luxate teeth, and this technique imparts forces to tooth particles that sever the periodontal ligament around tooth roots inside the socket and expand alveolar bone around tooth particles. These effects can result in extraction of the tooth particles or facilitate systematic forceps extraction of the tooth particles. This article presents basic oral surgery techniques for applying elevators to luxate teeth. Determination of the optimal luxation technique requires understanding of the functions of the straight elevator and the Cryer elevator, the concept of purchase points, how the design elements of elevator working ends and tips influence the functionality of an elevator, application of forces to tooth particles, sectioning teeth at furcations, and bone removal to facilitate luxation. The effectiveness of tooth particle luxation is influenced by elevator tip shape and size, the magnitude and the vectors of forces applied to the tooth particle by the tip, and sectioning and bone removal within the operating field. Controlled extraction procedures are facilitated by a dental operating microscope or the magnification of binocular surgical loupes telescopes, combined with co-axial illumination.

In 22 dogs with medial patellar luxation (MPL) of grade 3 or lower, resection of the vastus medialis oblique muscle, patellar anti-rotational suture, fascia lata overlap, and tibial tuberosity transposition (TTT) were undertaken to stabilize the patella without trochleoplasty. Data including signalment, clinical symptoms, details of the affected hindlimb, preoperative and postoperative patellar luxation grades, postoperative recovery time, and postoperative complications were obtained from medical records. The grade of lameness was evaluated preoperatively and postoperatively. Mean (${\pm}SEM$) grade of medial patellar luxation was $2.64{\pm}0.11$ preoperatively and $0.2{\pm}0.27$ postoperatively. Mean (${\pm}SEM$) grade of lameness was $1.73{\pm}0.27$ preoperatively and $0.18{\pm}0.15$ postoperatively. Patellar reluxation occurred in 1 of 22 (4.5%) cases requiring additional surgery. At final follow-up, 2 of the 22 (9.0%) dogs, including one with reluxation, had occasional lameness. Client-based questionnaire results demonstrated significant improvements in all parameters. Surgical treatment of MPL that included resection of the vastus medialis oblique without femoral trochlear groove deepening improved surgical outcomes in dogs with up to grade 3 MPL.

A nine-month-old male Jindo with non weight-bearing on the right forelimb in flexed position, pain and edema of the elbow, and resist elbow extension was brought to the Veterinary Teaching Hospital, Chungbuk National University. Elbow radiographs showed loss of humeroradial joint space and lateral displacement of the radius and ulna. Closed reduction was reported the best therapy in most cases of luxation of the elbow but conservative reduction was impossible. Open reduction of the luxated elbow was performed and ruptured collateral ligaments were identified. Displaced elbow was required bloody surgical operation and gentle reduction to restore elbow joint. Internal reduction of choice for elbow luxation with rupture of collateral ligament in the dog was a double locking-loop suture pattern. To ensure secure grasping of parallel bundles of ligament fibers to transverse bites of each suture were placed superficial to the longitudinal bites. All ligaments were repaired with 3-metric (size 2 USP) monofilament polypropylene suture. No complications have been noted during a five-month follow up.

세 마리의 소형견이 4단계의 내측 슬개골 탈구로 내원하였다. 세 마리 모두에서 일반적인 기존 수술 방법으로는 슬개골 탈구가 환납되지 않았다. 따라서 슬개골 탈구를 교정하기 위해 대퇴 단축 절골술이 실시되었다. 수술 후에 세 마리 모두 임상 증상이 개선되었고 합병증이나 재발은 확인되지 않았다. 대퇴 단축 절골술은 심한 골격 기형과 관련된 내측 슬개골 탈구가 있는 소형견에서 효과적인 치료 방법으로 고려될 수 있다.

본 증례는 외상으로 골유착된 견치를 탈구와 인위적 맹출 유도로 치료한 환자에 대한 것이다. 초진시에는 견치가 골유착되었다는 어떠한 증거도 발견되지 않아 하악에 가철식 장치와 악간 고무줄을 이용하여 인위적 맹출을 시도하였으나 3개월 후에도 전혀 움직임을 보이지 않았다. 이 시기에 견치는 생리적인 움직임을 전혀 보이지 않았고 타진시 날카로운 울림소리가 나는 것으로 골유착되었음을 확인하였다. 이에 골유착된 견치를 탈구시키고 인위적 맹출을 즉시 도모하여 교정적, 치주적으로 양호한 결과를 얻었기에 이에 보고하는 바이다.

8 kg, 9개월령 중성화 수컷 시바 이누견이 양측 후지의 간헐적인 파행 증상으로 내원하였다. 검사를 통해 3단계의 양측 슬개골 탈구가 진단되었다. 대퇴 사두근의 정상 배열을 회복하기 위해서 상대적으로 비침습적인 조면의 위치를 재배열하는 독특한 수술 방법을 적용하였다. 이 과정은 경골 능선을 따라 경골 조면의 내측 피질골을 절개하고, 경골 조면을 외측으로 변위시키기 위해 경골 능선의 내측에 피질골 나사못을 장착하는 방식으로 이루어졌다. 수술 후 3개월 검사에서 양측 후지의 파행과 슬개골 탈구가 개선된 것이 확인되었다. 이 수술 기법은 골격이 미성숙한 환자에서 내측 슬개골 탈구를 치료하기 위한 효과적인 방법으로 고려될 수 있다.

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.
