Abduction treatment in stable hip dysplasia does not alter the acetabular growth: results of a randomized clinical trial

Abstract Background The effect of bracing over stable dysplastic hips is not well known. This multicenter randomized trial aimed at demonstrating the adverse effects of abduction treatment versus continuous monitoring in infants aged 3 to 4 months of age. After 9 months and walking age, the measurement of the acetabular index on plain pelvis X-rays was used to determine persistent dysplasia. The mean u00b0 was 60. 5 b0 in the Pavlik harness group and 60. 0 u00b0 in the active surveillance network, at 12 weeks follow-up, and 60. 8 u00b0 in the active surveillance group was 60. 5 u00b0 in the Pavlik harness group. There were no treatment differences between the acetabular index at age ten months and walking age, according to an analysis of secondary results. Interpretation Pavlik's treatment of chronic, but sonographic dysplastic hips has no influence on acetabular growth. After eight weeks, eighty percent of the patients will have normal hip growth.

Biomechanical effect of metal augment and bone graft on cup stability for acetabular reconstruction of total hip arthroplasty in hip dysplasia: a finite element analysis

Abstract Background: Different methods of acetabular reconstruction with total hip arthroplasty for Crowe II and III of adult developmental dysplasia of the hip acetabular bone defect have been used clinically. Methods In the present study, autologous bone graft and metal augment were simulated in THA with several acetabular bone defect models. Using a finite element approach, the shell's contact pressure and micromotion between the shell and host bone were determined for testing shell stability. Results In the Massachusetts situation, the peak contact stress between shell and host bone was higher. For BG models, the increased load transfer path was different, while for MA models, the concentrated contact stresses were on the surface of MA.

Outcomes of computer-assisted peri-acetabular osteotomy compared with conventional osteotomy in hip dysplasia

Abstract Aim of the study The aim of the study was to determine the results after computer-assisted peri-acetabular osteotomy and conventional PAO procedures for hip dysplasia. The results of a computer-assisted PAO show that hip scores in patients with conventional PAO increased dramatically from 70. 0 points pre-operatively to 90. 7 points post-operatively, and in patients with computer-assisted PAO, from 74. 5 points pre-operatively to 94. 2 points post-operatively. The post-operative AHI and VCA angle were within the radiographic target zone in all patients with computer-assisted PAO. Some patients with conventional PAO had post-operative AHI and VCA angles outside of the target zone. Five of the 98 PAO hips underwent total hip arthroplasty, with an average follow-up period of 5. 4 years. In comparison to conventional PAO, adequate anterior and lateral coverage of the femoral head in patients with computer-asisted PAO resulted in no need for early conversion to THA, according to conventional PAO.

Acetabular deficiency in borderline hip dysplasia is underestimated by lateral center edge angle alone

Abstract Introduction The term u201cborderline hip dysplasiau201d was used in hip preservation surgery when the lateral center edge angle, which Wiberg traditionally referred to, was 18u201325u00b0. For example, the anterior and posterior wall index, and many radiographic measures have been used in recent years to determine the antero posterior coverage of the femoral head. Material and methods A retrospective analysis of 397 consecutive hips was done, all of whom were treated with triple pelvic osteotomy due to symptomatic hip dysplasia. Measured on all preoperative pelvic radiographs with a LCEA of 18u201325u00b0, acetabular index, AWI, and PWI were performed. The parameters' correlations between the intra- and interobserver correlations of the parameters was analyzed by intraclass correlation coefficients. Male acetabula seemed to be marginally more postero-laterally deficient than female acetabula, according to a Gender analysis. Male acetabula were more deficient postero-laterally than female.

Relationship between labral length and symptoms in patients with acetabular dysplasia before rotational acetabular osteotomy

ABSTRACT (About) The aim of this research was to determine the relationship between acetabular labular length and symptoms in patients with acetabular dysplasia. 218 patients with acetabular dysplasia who had undergone rotational acetabular osteotomy were identified in a retrospective medical record review. Laboratory parameters by radial magnetic resonance imaging were determined by 53 patients after implementing the inclusion and exclusion criteria, acetabular bone morphology parameters, anteroposterior pelvic radiographs, and labral parameters. There was no correlation between bone morphologic findings and JHEQ scores. In some models, the multiple linear regression results showed that anterior labral length was independently related to JHEQ subscales. Patients with symptomatic acetabular dysplasia were mainly in anterosuperior area, according to patients symptom, and not related to patientu2019s disease. A labral length can be a crucial objective image finding that can be used to determine the presence of cumulative hip instability.

Sleep quality and nocturnal pain in patients with femoroacetabular impingement and acetabular dysplasia

The aim of this study was to assess sleep quality in patients with AD and FAI syndrome. Methods The aim of this cross-sectional research involved 115 patients who complained of hip pain related to either FAI syndrome or AD. Using the Hip Outcome Score, Modified Harris Hip Score, and then Hip Pain Secondary to FAI syndrome and AD were used to determine one hundred fifteen patients with hip pain secondary to FAI syndrome and AD, as well as Hip Disability and Osteoarthritis Outcome Score. The Pittsburgh Sleep Quality Index was used to determine sleep quality. Patients with symptomatic FAI syndrome and AD have poor sleep quality, according to their conclusion. Even before the onset of osteoarthrosis of the hip, aching pain from a patient's hip pathology is linked to poor sleep. Patients with hip pains related to FAI syndrome and AD should be tested for sleep disturbances and may benefit from a multidisciplinary therapy approach.

Acetabular reconstruction with femoral head autograft in primary total hip arthroplasty through a direct anterior approach is a reliable option for patients with secondary osteoarthritis due to developmental dysplasia of the hip

Background information The direct anterior approach aims to treat developmental dysplasia with complete hip arthroplasty. Through a DAA with a minimal follow-up of 12 months, the aim of this research was to determine the potential, radiographic findings, and clinical outcomes of primary uncemented total hip arthroplasty with bulk femoral head autograft for acetabular augmentation through a DAA. Methods The objective was a retrospective, successive series of 29 primary total hip arthroplasty with acetabular graft augmentation with bulk femoral head autograft from March 2006 to March 2018 was discovered by a direct anterior approach. In both cases, the surgical indication was secondary osteoarthritis for developmental dysplasia of the hip. Conclusions Acetabular reconstruction with femoral head autograft in primary THA via a direct anterior approach seems to be a safe option for treating secondary osteoarthritis in patients with DDH Hartofilakidis grade A and B.

The “Outside-In” Lesion of Hip Impingement and the “Inside-Out” Lesion of Hip Dysplasia: Two Distinct Patterns of Acetabular Chondral Injury

Objective: To compare the acetabular chondral flap morphology observed during hip arthroscopy with medical and radiographic measurements underlying FAI and hip dysplasia. Patients undergoing hip arthroscopy by the senior author between 2013 and 2017 were included in the Outerbridge grade IV acetabular chondral flap. During an assignment into one of two radiographic groups, patients were observed with hip impingement/dysplasia, and group 1, lateral center edge angle > 20 for FAI, and group 2, LCEA u226420 with or without cam FAI. There was a strong correlation between chondral flap type and radiographic diagnosis. According to Altogether, 90% of group 1 hips had an outside-in lesion, and 88% of group 2 hips had an inside-out lesion. Conclusion: During hip arthroscopy, acetabular chondral flap type was seen, which in turn corresponds to radiographic signs of hip impingement and hip instability, according to radiographic indicators of hip impingement and hip instability.
