Total Hip Replacement in a patient with chronic coxofemoral joint dislocation is a challenging problem because chronic coxofemoral joint dislocation causes severe morphological changes. These challenging factors make surgery more difficult and increase the possibility of postoperative complications including cup implant dislocation and prosthetic joint luxation. All patients were diagnosed having at least 2 months of coxofemoral joint dislocation. On physical examination, crepitus was noted in the coxofemoral joint. Radiographs revealed hip joint dislocation with mild to severe degenerative changes. Total hip replacement was planned for all patients. Dorsal acetabular rim deficiency in 3 cases was augmented using a locking plate and polymethylmethacrylate bone cement. All cases have shown difficulty in prosthetic joint reduction. Pectineus and rectus femoris muscle origin were released in all cases. At 12 months follow up, all patients showed satisfactory ambulation. The issues on perioperative prosthetic joint reduction and luxation due to chronic coxofemoral joint luxation with muscle contracture and dorsal acetabular rim deficiency can be resolved by muscle releasing and dorsal acetabular rim augmentation.

Luxation of the hip is the most common luxation seen in small animals. Luxations are classified by the direction in which the femoral head lies in relation to the acetabulum and craniodorsal luxations are the most common type. Recommendations for treatment are based on the presence of preexisting disease, the type and duration of luxation and severity of concurrent injuries. In this study modified external skeletal fixation was used for craniodorsal coxofemoral luxation in 5 dogs. Luxated head Joint was reduced and fixator pins were applied into the greater trochanter, the middle point of iliac body and the lateral surface of sacroiliac joint in a closed fashion. Reduction was successful in 4 of the 5 operated limbs. Complications noted in this study included pin tract drainage, pin loosening and secondary fracture at the pin insertion site.

This study was performed in 41 dogs with unilateral or bilateral medial patella luxation (MPL) and/or cranial cruciate ligament rupture (CCLR). These dogs were classified into 4 groups according to MPL grading system. Radiographic evaluation was performed for pelvis and stifle joint in the dogs. Norberg, inclination, quadriceps and femoral varus angle were measured and analyzed with MPL grading and the existence of cranial cruciate ligament rupture. The Norberg and inclination angle showed no differences between 4 grading groups and between CCLR and no CCLR groups. However, quadriceps and femoral varus angle were statistically different between grade 1, 2 and grade 3, 4 groups. They also have shown the statistical difference between CCLR and no CCLR group. Further studies for how these parameters affect the prognosis and the results of surgical treatment of MPL should be needed.

A wild Whooper swan (Cygnus Cygnus) with limping due to an injured left pelvic limb in an accident was rescued on the seashore and transferred to the Jeju Wildlife Rescue Center on November 23rd, 2020. On physical examination, its body condition score was 1 out of 5 due to starvation and dehydration. The left coxofemoral joint was also examined by careful palpating and estimating the damage. Moderated soft tissue swelling and crepitus surrounding the hip joint were confirmed. Radiography and computed tomography (CT) were used together for an accurate diagnosis of the joint. By radiographs readings, it was difficult to accurately confirm the condition of the proximal femur due to superimposition of the synsacrum and internal organs. However, signs such as avulsion fracture of the femoral head and a few fragments around the joint were revealed by CT imaging. Besides, through three-dimensional (3D) image analysis of CT, the dislocated area and condition of the left hip joint could be accurately and easily confirmed. The diagnostic process showing in this paper could be used as a good reference for diagnosing coxofemoral joint luxation in wild swan.

A 3-year-old, 26 kg, castrated male Chow Chow was presented for assessment of weight-bearing lameness of the left hind limb. The patient had a history of triple pelvic osteotomy on the left side to correct hip dysplasia 2 years prior to his presentation of clinical signs and underwent total hip replacement on the right coxofemoral joint 1 year later. Upon physical examination, pain and crepitus were noted on the left hip joint during extension. Radiological examination revealed coxofemoral joint subluxation and moderate degenerative bone changes on the left hip joint and pelvic axis, which relates to acetabular angles that were changed after triple pelvic osteotomy (TPO). Preoperative computed tomography was used for 3-dimensional printing to establish an accurate surgical plan. The changed angles of the acetabulum after TPO were evaluated, and rehearsal surgery was performed using a 3-demensional printing bone model. Three months after the THR surgery, the function of the affected limb had improved, with no lameness. Complications, such as luxation and implant failure, were not observed until 6 months after the operation. Accurate evaluation of acetabulum angles and rehearsal surgery using a 3D-printed bone model is effective for total hip replacement after unsuccessful TPO.

Radiographic findings of degenerative joint disease (DJD) in the coxofemoral joints were studied in 108 dogs referred to Veterinary Medical Teaching Hospital, College of Veterinary Medicine, Seoul National University. Radiographic findings were identified with a extended ventrodorsal projection. Clinical signs such as pain in the affected joint, exercise intolerance, lameness, crepitation on flexion and extension of the joint and decreased range of motion, were shown in 40% and radiographic changes of bilateral coxofemoral joints were identified in 69% of a group of dogs. There are no sex predilections. Thirty-seven dogs were diagnosed as canine hip dysplasia (CHD; 10 cases), avascular necrosis of the femoral head (Legg-Calves-Perthes disease [LCPD]; 12 cases), fracture of the acetabulum (1 case), luxation(10 cases) and subluxation (15 cases), however, luxation and subluxation were identified in 11 dogs affected with CHD and LCPD. Causes of DJD in others (71case) were not identified. Radio-graphic findings identified included osteophyte formation at the attachment of the joint capsule (70%), sclerosis of the subchondral bone of the cranial acetabular edge (47%), remodeling of the femoral head (34%), thickening of the femoral neck(31%), perichondral osteophyte formation (31%), joint laxity (30%) and so on. All of the dogs diagnosed as CHD were large breed such as Retriever, Germain Shepherd, and Weimaraner and their age was under 1 year. This condition occurred bilaterally in 70% of affected animals. Dogs diagnosed as LCPD were young (under 1 year), small breed dogs. The incidence of LCPD is greater in Yorkshire Terrier, Miniature Pinscher and Poodle. This condition occurred unilaterally in 67% of affected animals. Clinical signs of dogs with unknown cause were shown in 15% and this condition occurred bilaterally in 75% of affected animals. Radiographic findings varied with patient's age and breed, however, the most common finding was osteophyte formation at the attachment of the joint capsule.

Background: The TightRope System is a device developed to provide extracapsular stabilization of the cranial cruciate ligament (CCL) rupture in canine stifles. I was then also employed for the extra-articular treatment of shoulder instability and for the intra-articular treatment of hip luxation in dogs and cats. Objectives: To evaluate the feasibility of the Mini-TightRope (mTR) System for the intraarticular treatment of CCL rupture in small breed dogs. Methods: A cadaveric canine model was used to record the steps of the surgical procedure. Five client owned dogs weighing from 8 to 10 kg and from 2 to 12 years of age were enrolled in the prospective study in which the mTR device was implanted in the stifle joint to replace the ruptured CCL. The dogs were graded using the Bologna Healing Stifle Injury Index (BHSII) and radiographic osteoarthritis (OA) scores. Results: The outcomes obtained at the time of the surgery (T0) and for the following 12 months (T12) showed an improvement in the functional parameters (BHSII from a median of 74.3 [range, 58.1-82.4] at T0 to 95.6 [range, 94.1-99.3] at T12]). The OA did not change in 3 dogs and increased by only 1 point in 2 dogs. Conclusions: In this preliminary study, the mTR was a successful and repeatable intraarticular surgical procedure for all dogs. Additional studies related to the clinical application of the technique in medium-large dogs should be encouraged.

관절염은 증상 발현 이후 치료 효과가 매우 더디게 나타나기 때문에 조기 발견과 그에 따른 적절한 처치가 무엇보다도 중요하다. 따라서 많은 연구자들은 관절염 질환모델을 통한 조기 진단 인자의 발견을 위해 그 동안 지속적으로 연구해 오고 있는 실정이다. 개에서 고관절 탈구와 이형성은 정형외과에서 흔한 질병으로 고관절의 관절염과 관련이 있는 것으로 알려져 있다. 관절염 유발을 위해서는 흔히 대퇴골두인대의 절단이 필요한데 이는 대퇴골두인대의 절단을 통해 관절의 움직임을 극대화 시키기 위한 방법이다. 지금까지 유발 관절염에 대한 관절액의 분석을 위해서 프로테오믹스를 이용한 연구는 매우 드물다. 실험동물은 열 마리의 건강한 수컷 비글견을 사용하였으며, 나이는 2-3세 (평균 $2.57{\pm}0.20$ 살), 몸무게는 10 - 16kg (평균 $11.90{\pm}1.68 kg$) 이었다. 실험 기간 동안 방사선검사, 일반혈액검사, 혈청화학검사상 특이사항이 없었다. 실험동물은 술 후 평균 일주일에 보행을 하였다. Proteomic 검사 상, 관절액의 단백질 변화가 보여졌으며 단백질의 변화의 유의성검증을 위해 ANOVA (p < 0.05)테스트를 실시하였다. 실험 결과로는 프로테오믹스 검사에서는2개의 단백질 점(Vitamin D-binding protein precursor, ANOVA (p < 0.004); Kinogen-1, ANOVA (p < 0.039))이 유의성 있게 증가되는 모습이 확인하였다(ANOVA (p < 0.05)). 이 두 단백질은 류마티스 관절염, 혹은 퇴행성 관절염에서도 증가하는 경향이 있는 것으로 알려져 있다. 이 실험에서 관절염 유발 방법으로 이용한 대퇴골두인대의 절단은 관절염 유발에 적절한 모델이었으며 또한 고관절에서 관절액 단백질의 변화를 유도할 수 있는 적합한 방법이라고 생각된다. 따라서 관절염 유발 모델에서 프로테오믹스를 이용한 관절액 변화의 관찰은 실제 임상에 있어서 관절염 조기 진단방법으로 매우 유용성이 있을 것으로 생각된다.
