OBJECTIVE: To report use of ultrasonographic examination of the coxofemoral joint, a surgical technique for repair of craniodorsal coxofemoral dislocation, and outcome. STUDY DESIGN: Clinical case reports. ANIMALS: Calves (n=4) with coxofemoral luxation. METHODS: Craniodorsal coxofemoral luxation was diagnosed by physical examination, radiographic, and ultrasonographic findings. Open surgical reduction of the femoral head was performed using a modified caudal approach. RESULTS: Craniodorsal luxation of the femoral head and the presence of an intact femoral neck were confirmed by ultrasonography. All luxations were successfully reduced and reluxation did not occur. At follow-up, 1 heifer had calved and 1 was 5 months pregnant. One calf died of bronchopneumonia 6 days after surgery. One calf had severe coxofemoral degenerative joint disease diagnosed (ultrasonography, radiography, and arthrocentesis) 3 months after surgery and confirmed by necropsy. CONCLUSION: Ultrasonography proved to be a simple and effective non-invasive technique for diagnosis of coxofemoral luxation. Immediate surgical intervention in hip dislocation in calves is necessary to avoid unnecessary trauma to subchondral structures. In calves, open instead of closed surgical reduction appears preferable because it allows access to the acetabular cavity for removal of debris. CLINICAL RELEVANCE: Ultrasonography should be considered a supplementary but not an alternative to radiographic examination for diagnosis of coxofemoral luxation and for follow-up examinations after reduction. 相似文献

Bilateral subchondral cystic lesions of the femoral head in a horse resulted in lameness. The lesions had resulted in degenerative disease in the left coxofemoral joint. The cause of lameness was confirmed by use of intra-articular anesthesia, joint fluid analysis, and radiography. Subchondral cystic lesions involving the femoral head should be considered in the differential diagnosis of equine lameness localized in the upper portion of the hind limb. 相似文献

Hip luxations have been reported in many ruminants, and several treatments have been described for them. However, successful closed reduction of hip joint luxation has not been reported in goats to date. This case report describes the closed reduction of coxofemoral luxation in a three-month-old male Saanen dairy goat. The goat showed non-weightbearing lameness and abnormal mobility of the proximal right hindlimb. Luxation of the right coxofemoral joint in craniodorsal direction was diagnosed by radiography. The femoral head was repositioned under sedation, and physiotherapy including non-weightbearing hindlimb movement and supported walking exercise was performed. Fifteen days after closed reduction the animal was discharged from the clinic. At that time the animal was sound at a slow walk but lameness was still present at faster gaits. Follow-up examinations revealed normal development of the animal, which subsequently showed no lameness and served successfully as a breeding goat. 相似文献

A 30-yr-old untamed European female brown bear (Ursus arctos arctos) with a craniodorsal luxation of the right femoral head and bilateral degenerative joint disease of the coxofemoral joint had a femoral head and neck excision following unsatisfactory conservative medical therapy. The bear was injected with zolazepam-tiletamine, and anesthesia was induced with i.v. thiopental and maintained with isoflurane in oxygen via endotracheal tube. A lumbosacral epidural injection of medetomidine-bupivacaine provided additional analgesia. Slight initial cardiorespiratory depression was counteracted with fluid and inotropic drug administration and ventilatory assistance. The bear's gluteal muscle anatomy differs from that of the dog. Recovery was uneventful. The bear was confined indoors for 6 wk and was able to ambulate normally within 6 mo. 相似文献

We report radiographic changes and clinical results seen in the proximal femur and coxofemoral joint of 7 young dogs following intramedullary pinning. Changes seen radiographically included coxa valga, a small malformed femoral head, a short thin femoral neck, and coxofemoral subluxation. Epiphyseal trauma, ischemia, and mechanical impairment of normal femoral neck growth due to presence of the intramedullary pin are discussed as possible etiologic factors. 相似文献

Femoral head ostectomy was performed in six horses, three ponies, and four cattle for treatment of fractures of the femoral capital physis, coxofemoral luxation, fractured acetabulum, or severe degenerative joint disease. The procedures were performed via a cranial approach that did not involve osteotomy of the greater trochanter. A dorsal approach for femoral head ostectomy via osteotomy of the greater trochanter was evaluated in three healthy adult ponies. Three animals (2 ponies, 1 calf) were euthanatized within a month and one horse was euthanatized at year 2 due to postoperative complications. Nine animals were discharged to owners and six of them fulfilled their intended functions of breeding, milking, and being kept as companions. One horse was lost to follow-up and two horses died of causes unrelated to the surgery. All surviving animals had a residual lameness that was described by owners as mild to moderate. None of the horses were used as riding animals. The mean age and weight of 10 animals that regained weight-bearing locomotion was 3.1 months and 84 kg; for three unsuccessful cases it was 34 months and 174 kg. We concluded that femoral head ostectomy was a viable salvage procedure for large animals with capital femoral physeal fracture, chronic coxofemoral luxation, or acetabular fracture. Surgical prognosis appeared to be favorable in young cattle and fair in young horses or ponies weighing less than 100 kg. Osteotomy of the greater trochanter resulted in superior exposure of the intact coxofemoral joint and allowed easier, less traumatic surgical luxation of the joint to facilitate femoral head ostectomy. 相似文献

An abnormality of the coxofemoral joint is recognized when the articular cartilage sliding interface between the femoral head and the acetabulum is interrupted. The article considers the pathologic conditions that may affect the normal coxofemoral articulation and are responsive to excision arthroplasty. Techniques of excision arthroplasty and the biceps femoris muscle sling technique are described. 相似文献

OBJECTIVE: To report the use of arthroscopy and total hip arthroplasty (THA) for management of intermediate grade fibrosarcoma of the femoral head in a dog. STUDY DESIGN: Clinical case report. ANIMAL: A 6-year-old spayed female Rottweiler presented for evaluation of acute-onset of lameness of the right pelvic limb of approximately 10 days duration. METHODS: Coxofemoral arthroscopy was performed to obtain fine needle aspiration and Jamshidi biopsy of a lytic lesion of the femoral head. A cemented THA was performed removing as much of the femoral neck and proximal femur as possible while not compromising implant or joint stability. RESULTS: Histologic evaluation of specimens from the femoral head and neck remnants confirmed an intermediate grade fibrosarcoma. Fifteen months after THA, subjectively there was normal use of the right limb with only limited decrease in range of motion and mild muscular atrophy. Radiographs demonstrated stationary positioning of the THA implants. CONCLUSIONS: Arthroscopy of the coxofemoral joint is an effective diagnostic tool for evaluation of disease of the articular structures and canine total hip replacement may be an appropriate means of limb salvage in rare cases of disease of the femoral head. CLINICAL RELEVANCE: This case provides support for the use of coxofemoral arthroscopy as a diagnostic tool as well as an aid in acquiring representative intraarticular tissue samples. Additionally, the case presented demonstrates the potential use of THA as a limb sparing technique in cases of disease affecting the femoral head of dogs. 相似文献

An arthroscopic procedure for examination of the coxofemoral joint was developed in nine foals (four cadavers, five anesthetized) to determine if access was sufficient for evaluation and surgical treatment of intra-articular lesions. The joint was distended and the arthroscope inserted through the notch (incisura trochanterica) between the cranial and caudal parts of the greater trochanter. This portal allowed examination of the cranial, lateral, and caudal aspects of the joint. Mechanical distraction of the joint through an instrument portal located 2 to 4 cm cranial and 1 to 2 cm ventral to the arthroscope portal allowed examination of the ligament of the head of the femur, the femoral head, and articular and nonarticular surfaces of the acetabulum. Adduction and rotation of the limb improved visualization of the craniomedial and caudomedial portions of the femoral head. Traction applied to the distal limb allowed visualization of the same structures that were observed when mechanical distraction was used. Traction also created space for placement of surgical instruments into the joint through the instrument portal. Access to most regions of the joint was adequate, but access to the caudal and medial aspects of the joint was limited. Three foals were killed while they were anesthetized, and their coxofemoral joints were dissected. Two foals were allowed to recover from anesthesia and were observed for 30 days after surgery. One foal was mildly lame for 2 days after surgery. The other foal was not lame after surgery. The incisions healed, and the coxofemoral joints were radiographically normal by postoperative day 30. 相似文献

Dogs with CHD are born with normal hips that subsequently undergo varying degrees of subluxation of the coxofemoral joint. Although the etiology of CHD is multifactorial, the pathogenesis or stages of change within the affected coxofemoral joint(s) are similar regardless of cause. With the onset of the disease, there are progressive structural changes including joint laxity and femoral head subluxation; swelling, stretching, fraying, and eventual rupture of the teres ligament; a shallow, flattened acetabulum, deformity of the head; erosion of articular cartilage, eburnation of subchondral bone, DJD; and periarticular osteophyte formation. 相似文献

The effectiveness of ultrasound in depicting the normal anatomy of the coxofemoral joint in puppies was evaluated. Ultrasound images were obtained from twenty Springer Spaniel puppies ranging from one day to twelve weeks of age. The anatomy of the hip joint could be identified up to eight weeks of age. By twelve weeks of age the degree of ossification prevented complete hip joint evaluation. Three different views were utilized. The longitudinal and dorsolateral views were the most useful. Motion of the femoral head within the acetabulum could be observed. Measurements of the acetabulum, femoral head and joint space could be obtained however these measurements were inconsistent. The technique appears to be useful for depicting the anatomy of the neonatal coxofemoral joint however, additional studies utilizing both normal and dysplastic puppies are recommended to determine if this examination will be useful in discriminating between normal and dysplastic puppies. 相似文献

A total hip arthroplasty was performed in a small equine patient with a history of traumatic subluxation of the coxofemoral joint during infancy resulting in severe degenerative changes to the femoral head and acetabulum. The transtrochanteric surgical approach used to expose the joint, as well as the technique and technology to replace the joint, is described. The patient was weightbearing within 24 h of surgery and walking successfully without sling support 4 days post operatively. On the fifth post operative day, the patient abruptly deteriorated and succumbed to multiple pulmonary thromboemboli and a jejunal infarction. Despite the systemic complications in this case, the initial short‐term success of this treatment option indicate its potential to be considered in the management of equine coxofemoral joint disease/lesions. 相似文献

Osteochondrosis affecting the acetabula in horses is rarely reported. Osteochondrosis dissecans in foals only a few weeks old is also an uncommon finding. Lesions compatible with osteochondrosis dissecans in the acetabulum were found to be the cause of a chronic coxofemoral lameness in a 3-week-old Arabian filly. The history, physical examination findings, joint fluid analysis, gross pathologic and histopathologic findings are described. 相似文献

Avascular necrosis of the femoral head was diagnosed in a 5-month-old Schipperke, before the development of femoral head and neck collapse and resultant degenerative joint disease. External coaptation, consisting of an Ehmer sling, was used to prevent the bearing of weight during revascularization and reossification of the subchondral bone. Results of pelvic radiography (at 10 and 24 weeks) indicated that the early use of conservative treatment was successful in promoting resolution of the aseptic necrosis and in maintaining normal coxofemoral anatomic features and function. 相似文献

A 6-year-old German Shepherd dog was evaluated for hind limb lameness. When a diagnosis, could not be achieved using radiography and ultrasonography, bone scintigraphy was performed to look for occult lameness or the presence of multiostic disease. Bone scintigraphy was useful in identification of increased radiopharmaceutical uptake in the thoracic spine and right coxofemoral joint, which directed further testing leading to the diagnosis of discospondylitis, septic arthritis of the coxofemoral joint, and a urinary tract infection. 相似文献

OBJECTIVE: To determine whether dorsolateral subluxation (DLS) of the femoral head reflects osseous conformation of the coxofemoral (hip) joint and represents a property distinct from maximum passive laxity of the hip joint in dogs. ANIMALS: 14 Labrador Retrievers, 16 Greyhounds, 58 Greyhound-Labrador Retriever mixed-breed dogs, and 1 Rottweiler. PROCEDURES: DLS of the femoral head (DLS score) and passive laxity of the hip joint (distraction index) were determined radiographically in 3 groups of dogs: not treated (167 joints of 84 dogs); before and after injecting 2 ml of hyaluronan into 25 hip joints of 13 dogs; and before and after unilateral triple pelvic osteotomy in 5 dogs. Results of the 2 methods were compared for each group. RESULTS: In untreated dogs, the correlation coefficient (r) of DLS score versus distraction index was -0.73 and -0.69 for 84 left and 83 right hip joints, respectively. Mean coefficient of determination (r2) for both hips was 0.5. Mean DLS score did not differ before and after intra-articular injection of hyaluronan into either hip joint, whereas mean distraction index increased significantly after intra-articular injection. Unilateral triple pelvic osteotomy resulted in a significant increase in DLS score, compared with values obtained before surgery. However, distraction index before and after surgery did not differ significantly. CONCLUSIONS AND CLINICAL RELEVANCE: The DLS test assesses the congruity of the acetabulum and the femoral head in a canine hip joint and thus represents a characteristic distinct from maximum passive laxity. The DLS score and the distraction index evaluate different components of hip joint stability. 相似文献

A five‐year‐old male German shepherd dog presented with traumatic craniodorsal luxation of the right coxofemoral joint with pre‐existing moderate hip dysplasia. A femoral head and neck ostectomy was performed. The patient was sedated with acepromazine and morphine administered intramuscularly. A lumbosacral epidural was performed using a combination of morphine and ropivacaine. Intraoperatively, an infusion of medetomidine, morphine, lidocaine, and ketamine was administered intravenously, and oxygen was administered via facemask. Heart rate, respiratory rate and oscillometric arterial blood pressures were monitored. Postoperatively, carprofen was administered once subcutaneously. On the day of hospital discharge, carprofen and tramadol were administered orally every 12 hours. Twenty‐one days later, the dog was doing well and the surgical staples were removed. Sedation with acepromazine and morphine, administration of an epidural containing morphine and ropivacaine, and intraoperative sedation with medetomidine, morphine, lidocaine and ketamine were suitable for femoral head and neck ostectomy . 相似文献

Objective— To report use of a cementless total hip prosthesis in an alpaca.
Study Design— Case report.
Animals— Alpaca (n=1) with chronic craniodorsal coxofemoral luxation.
Methods— A 2.5-year-old Suri alpaca, 3 months pregnant, was admitted for evaluation of acute onset severe left hind limb lameness (grade 4/5) of 6 weeks duration. After diagnosis of craniodorsal luxation of the left femoral head, total hip replacement (THR) using a cementless implant was performed because of the poor prognosis for reduction of a chronic luxation.
Results— A press-fit prosthesis was used and the alpaca delivered a live cria 8 months later. Persistent mild mechanical lameness remained after surgery, with moderate reduction in mobility of the coxofemoral joint. The prosthesis was stable and correctly positioned at 7 weeks and at 9 months. There was mild exostosis surrounding the proximal aspect of the femur at 9 months, and Steinmann pins used to repair the trochanteric osteotomy were removed because of migration. At 1 year, the alpaca has a slight gait abnormality, remains with the herd on pasture and has been re-bred.
Conclusion— Chronic coxofemoral luxation in an alpaca can be managed by THR.
Clinical Relevance— THR is a viable treatment option in alpacas with severe coxofemoral disease. 相似文献

Radiographic evaluation of the pelvis in standing horses has been used to diagnose fractures of the pelvis, head and greater trochanter of the femur, and luxations of the coxofemoral joint. Coxofemoral luxation injuries are more common in smaller horse breeds and donkeys, but, due to their size, the standing ventrodorsal projection is not possible, as there is insufficient space to place the radiography equipment under the animal's abdomen. The objective of the study was to report the advantages and limitations of the use of an oblique radiographic projection to diagnose unilateral craniodorsal coxofemoral luxation in 3 ponies and a donkey performed with the animals standing under light sedation. All cases had severe unilateral hindlimb lameness and asymmetry of the gluteal region; 2 also had concurrent intermittent upward fixation of the patella. A standing dorsolateral 20–30° ventral oblique radiograph of the affected coxofemoral joint was performed in all cases to obtain a definitive diagnosis. Radiography of the coxofemoral joint in standing ponies and donkeys can be carried out to identify craniodorsal coxofemoral luxation avoiding the need for general anaesthesia. 相似文献

O bjectives : The objective of this study was to describe initial and long-term results of open reduction and transarticular pinning for treatment of coxofemoral luxations in cats.
M ethods : Cats were treated by open reduction and transarticular pinning for coxofemoral luxation over a five year period at two institutions. Follow-up assessment included orthopaedic examination, radiography and owner questionnaires.
R esults : Twenty cats were included in the study (14 males and six females). One cat was affected bilaterally. Mean time to follow-up was 21 months. Seventeen joints were stabilised with a 1·6 mm pin, three with 2·0 mm pins and a 1·2 mm pin was used in the remaining joint. An Ehmer sling was not utilised in any case. All transarticular pins except one were removed (mean 3·5 weeks), with all hips still in reduction The overall success rate was 77 per cent, with two reluxations and one resorbed femoral head noted on radiographs of 13 joints followed long term. All 20 owners reported good to excellent long-term functional outcome for their cats.
C linical S ignificance : Results from this study indicate that transarticular pinning for stabilisation of coxofemoral luxation in cats can provide a good long-term outcome without sacrificing the integrity of the coxofemoral joint. 相似文献
