We report a case of Klippel-Trenaunay-Weber syndrome in a 31-year-old woman who presented with hypertrophy of the left leg. She had severe osteoarthritic changes in the left hip joint secondary to the lack of acetabular coverage of the femoral head as the result of lateral inclination of the pelvis owing to leg-length discrepancy of 4 cm. The centre-edge angle (coverage ratio of the acetabulum to the femoral head) was improved from 15° to 33° after a foot lift. She underwent osteotomy and lengthening of the normal contralateral tibia using a Taylor spatial frame. Hip arthroplasty could be avoided as osteoarthritic changes of the hip joint had improved.

Background: Hip dysplasia (HD) is the most common non-traumatic orthopedic disease in large breed dogs. Treatment is chosen according to the severity of the condition, the age of the dog and the involvement of osteoarthritis (OA). For puppies up to 20-weeks-old, surgical treatment by the juvenile pubic symphysiodesis (JPS) technique can be performed. This procedure promotes the ventrolateral rotation of the acetabulum over the femoral head, which improves hip joint congruence and stability. The objective of this study is to report the case of a young dog with HD treated with JPS and pectineus myectomy. Clinical and radiographic outcomes were assessed for up to one year after surgery.Case: A 17-week-old Saint Bernard puppy was attended at the University Veterinary Hospital showing abnormal weight bearing and lameness in pelvic limbs, without history of previous trauma. On orthopedic examination, there was a marked hypotrophy of the pelvic limb muscles, severe pain and laxity in the hip joints, and positive feature in the Ortolani test. The hip joint subluxation angle (SA) and reduction angle (RA) were measured. A radiographic study was carried out to evaluate the hip joints and measure the Norberg angle (NA), distraction index (DI), acetabular angle (AA) and dorsal acetabular rim angle (DARA). The 20-week-old dog underwent surgical treatment by JPS technique. A ventral surgical approach to the pubis was performed and the pubic symphysis was cauterized with electrocautery. Partial pectineus myectomy technique was also performed. Drug therapy and restriction of physical activities were indicated in the early postoperative. The dog was evaluated by clinical and radiographic examinations at 4 months and 1 year after the surgical procedure. In the reassessment after 4 months of surgical treatment, the patient showed improvement in clinical signs, with mild lameness and absence of painful sensitivity in the movement of the hip joints. Radiographically, hip joint incongruity was observed, but with progressive improvement in the values of the measured variables. In the clinical examination 1 year after the procedure, the dog showed satisfactory weight bearing with slight lameness in pelvic limbs in the running gait. There was improvement in the thigh muscles and no painful signs were observed in the hip joints, but a positive result was detected in the Ortolani test. In the radiographic examination, bilateral articular incongruity was still observed, however, there was a mild improvement in the coverage of the acetabulum over the femoral head. The measured angles and indices showed favorable results regarding the recovery of hip joint stability and proper development.Discussion: Studies evaluating the JPS technique for the treatment of HD have shown to be a relatively simple and effective procedure, which allows altering the acetabular coverage, reducing the development of HD and the progression of OA. The need for an early diagnosis of this condition is essential, so that the JPS technique can be used in young dogs and offer effective results. In the present report, in the late postoperative period, the dog showed improvement in clinical signs, with favorable weight bearing and ambulation in pelvic limbs, recovery of limb muscles, absence of pain in the hip joints and decrease in RA and SA. Radiographically, the reduction in joint subluxation, improvement in acetabular coverage over femoral heads, increase in NA and AA, reduction in DI and DARA are evidence of the favorable outcome of ventrolateral rotation of the acetabulum after surgical treatment. The surgical technique used was effective, which enabled the dog to recover the functional use of the pelvic limbs and improve the quality of life.Keywords: hip dysplasia, juvenile pubic symphysiodesis, hip joint, osteoarthritis, dog.Título: Sinfisiodese púbica juvenil associada à miectomia do pectíneopara tratamento de displasia coxofemoral em cãoDescritores: displasia coxofemoral, sinfisiodese púbica juvenil, coxofemoral, osteoartrite.

Aims The lateral centre-edge angle (LCEA) is a plain radiological measure of superolateral cover of the femoral head. This study aims to establish the correlation between 2D radiological and 3D CT measurements of acetabular morphology, and to describe the relationship between LCEA and femoral head cover (FHC). Methods This retrospective study included 353 periacetabular osteotomies (PAOs) performed between January 2014 and December 2017. Overall, 97 hips in 75 patients had 3D analysis by Clinical Graphics, giving measurements for LCEA, acetabular index (AI), and FHC. Roentgenographical LCEA, AI, posterior wall index (PWI), and anterior wall index (AWI) were measured from supine AP pelvis radiographs. The correlation between CT and roentgenographical measurements was calculated. Sequential multiple linear regression was performed to determine the relationship between roentgenographical measurements and CT FHC. Results CT-measured LCEA and AI correlated strongly with roentgenographical LCEA ( r = 0.92; p < 0.001) and AI ( r = 0.83; p < 0.001). Radiological LCEA correlated very strongly with CT FHC ( r = 0.92; p < 0.001). The sum of AWI and PWI also correlated strongly with CTFHC ( r = 0.73; p < 0.001). CT measurements of LCEA and AI were 3.4° less and 2.3° greater than radiological LCEA and AI measures. There was a linear relation between radiological LCEA and CT FHC. The linear regression model statistically significantly predicted FHC from LCEA, F(1,96) = 545.1 (p < 0.001), adjusted R2 = 85.0%, with the prediction equation: CT FHC(%) = 42.1 + 0.77(XRLCEA) Conclusion CT and roentgenographical measurement of acetabular parameters are comparable. Currently, a radiological LCEA greater than 25° is considered normal. This study demonstrates that those with hip pain and normal radiological acetabular parameters may still have deficiencies in FHC. More sophisticated imaging techniques such as 3D CT should be considered for those with hip pain to identify deficiencies in FHC. Cite this article: Bone Jt Open 2022;3(1):12–19.

Morphological abnormalities such as cam deformity or growth disturbances can have a detrimental effect on the smooth function of the hip joint. This case reports an attempt to salvage the hip joint of a young patient with a posttraumatic growth disturbance of the femoral head using a fresh osteochondral allograft. This treatment has been used very rarely in the femoral head due to the presumed tenuous blood supply of the head and the perceived risk of nonunion or progressive avascular necrosis. The patient in this case had persistent pain and mechanical symptoms leading to hip replacement. A detailed analysis of the retrieved femoral head demonstrated durability and healing of the grafts based on gross inspection, histology of bone and cartilage, and microCT analysis. This case is the first report to our knowledge of a detailed histological and radiographic analysis of the fate of osteochondral allografts of the femoral head. We hope that this case provides justification for the use of osteochondral allografts of the femoral head for other indications such as femoral head fractures, avascular necrosis, and benign epiphyseal tumors of the femoral head in an effort to avoid arthroplasty in young patients. The authors have obtained the patient’s informed written consent for print and electronic publication of the case report.

Purpose: The anterior centre-edge angle (ACEA) describes anterior acetabular coverage on false profile radiographs. Variability associated with pelvic tilt, radiographic projection, and identifying the true anterior edge, causes discrepancies in measuring an accurate ACEA. Computed tomography (CT) has the potential of improving the accuracy of ACEA. However, because the ACEA on sagittal CT has been shown to not be equivalent to ACEA on false profile radiographs, the normal range of ACEA on CT currently remains unknown and cannot reliably be used to determine over/under coverage. We therefore asked: what is the normal variation of ACEA corrected for pelvic tilt on sagittal CT and how does this compare to dysplastic hips? Material and Methods: A retrospective review was conducted on patients 10–35 who underwent CT for non-orthopedic related issues and patients with known hip dysplasia. The ACEA was measured on a sagittal slice corresponding to the centre of the femoral head on the axial slice and adjusted for pelvic tilt. A statistical comparison was then performed. Results: A total of 320 normal patients and 22 patients with hip dysplasia were reviewed. The mean ACEA for all ages was 50° ± 8°, (range: 23–81º), with a larger mean ACEA for males (51°) than females (49°). The ACEA mean for dysplastic hips was 30° ± 11° with a statistically significant difference in mean from the normal hip group ( p < 0.0001). Conclusion: The ACEA can be reliably measured on sagittal CT and significantly differs from dysplastic hips. ACEA measurements above 66° or below 34° may represent anterior over and under coverage.
