Project description:This study examined the outcomes of ultrasound-monitored Pavlik harness treatment in 25 infants (2 boys and 23 girls) representing a total of 31 cases of developmental dysplasia of the hip of Graf type IIc or more severe. For all infants, Pavlik harness treatment started after ultrasonographic diagnosis in our clinic. If there was no improvement by the third week of follow-up, the harness treatment was discontinued. Of the 25 patients (31 hips), 16 patients (18 hips) were successfully treated with the Pavlik harness. The effects of age at start of treatment, gender, side of pathology, first clinical evaluation findings, bilaterality, and Graf type on Pavlik harness treatment success were analysed. We found that the outcome of treatment with the Pavlik harness was related to Graf type, age at start of treatment, and bilaterality.

Project description:BackgroundThe Pavlik harness is the most common initial treatment for developmental dysplasia of the hip worldwide. During treatment, parents are required to re-apply the harness at home. Teaching parents how to apply the harness is therefore paramount to success. While simulated learning for medical training is commonplace, it has not yet been trialed in teaching parents how to apply a Pavlik harness.MethodsA group of parents underwent a simulated learning module for Pavlik harness application. Parents were evaluated pre- and post-exposure and at one month after testing. A validated objective structured assessment of technical skill (OSATS) and a global rating scale (GRS) specific to Pavlik harness application were used for evaluation. A control group of parents was also tested at both time points. A clinical expert group was used to determine competency. ANOVA and t tests were used to assess differences between groups and over time.ResultsParent scores on the OSATS improved to the level of expert clinicians both immediately post-intervention and at retention testing. However, on the GRS, only half were considered competent due to their inability to achieve the required hip positions. The control group did not improve nor were they considered competent.ConclusionsThe use of a simulated learning module improves both the confidence and skill level of parents in the application of the Pavlik harness. However, the challenges parents face in understanding the more detailed subtleties of medical care suggest that they still require an appropriate level of supervision by clinicians to ensure effective treatment.

Project description:PurposeSome articles have focused on the effectiveness of the Pavlik harness treatment for unstable and dislocated hips, yet data on monitoring its effectiveness with the acetabular index remains elusive. Therefore, this study aimed to assess Pavlik harness effectiveness in infants ≤6 months diagnosed with grade I developmental dysplasia of the hip using acetabular index improvement and identify the possible predictors of successful Pavlik harness treatment.MethodsA retrospective review of infants with grade I acetabular dysplasia treated with a Pavlik harness and monitored with anteroposterior pelvis X-rays at presentation and follow-up. Successful treatment was defined as achieving an acetabular index <30°.ResultsA total of 231 infants with acetabular dysplasia were treated with a Pavlik harness. A successful outcome was achieved in 135 infants (58.4%). Younger age, lower initial acetabular index, and patients with unilateral developmental dysplasia of the hip were significant predictors of a successful outcome. An age of 4.5 months or older was found to be the threshold for an unsuccessful result following Pavlik harness treatment, with a sensitivity of 65.2% and specificity of 57.3%. An initial acetabular index of 35.5° was found to be the threshold for an unsuccessful result, with a sensitivity of 83.7% and specificity of 61.5%.ConclusionPavlik Harness's success in correcting the acetabular index in acetabular dysplasia patients was related to unilateral cases, a younger age at presentation, and a lower initial acetabular index. The thresholds for unsuccessful treatment were an age of 4.5 months or greater and an acetabular index of 35.5° or higher.

Project description:BackgroundDevelopmental dysplasia of the hip (DDH) is a common musculoskeletal disorder in newborns, ranging from mild dysplasia to complete dislocation. Early detection and intervention are crucial for managing DDH. However, in some cases, standard orthopedic treatments such as the Pavlik harness fail, and alternative approaches are needed. Our study explores the possibility that manual therapy, specifically the Mézières-Bertelè Method (MBM), could be beneficial in cases of DDH that are resistant to conventional treatments.Case descriptionWe present a case of a 20-month-old female who had been suffering from persistent DDH (Graf's type IIIC on the left), pain and limping, despite previous conventional treatments, including the Pavlik harness. The patient received daily MBM sessions for six months, followed by maintenance sessions every two months.OutcomesAfter undergoing the MBM treatment, the patient showed clinical improvements, such as normal neuromotor development and restored hip joint parameters. We observed normal walking and running abilities, and X-ray parameters returned to normal levels. The patient sustained positive outcomes during long-term follow-up until the age of 7.ConclusionThe MBM manual therapy was used to treat a challenging case of DDH resistant to conventional treatment. This case report suggests a possible correlation between manual therapy and improved outcomes in resistant DDH and highlights the potential relevance of addressing the inherent musculoskeletal components of the condition.

Project description:BackgroundDevelopmental dysplasia of the hip is characterized by abnormal acetabular and femoral geometries that alter joint loading and increase the risk of hip osteoarthritis. Current understanding of biomechanics in this population remains isolated to the hip and largely focused on level-ground walking, which may not capture the variable loading conditions that contribute to symptoms and intra-articular damage.MethodsThirty young adult females (15 with dysplasia) underwent gait analysis during level, 10° incline, and 10° decline walking while whole-body kinematics, ground reaction forces, and electromyography (EMG) were recorded. Low back, hip, and knee joint kinematics and internal joint moments were calculated using a 15-segment model and integrated EMG was calculated within the functional phases of gait. Dependent variables (peak joint kinematics, moments, and integrated EMG) were compared across groups with a one-way ANOVA with multiple comparisons controlled for using the Benjamini-Hochberg method (α = 0.05).FindingsDuring level and incline walking, patients with developmental dysplasia of the hip had significantly lower trunk flexion angles, lumbar and knee extensor moments, and erector spinae activity than controls. Patients with developmental dysplasia of the hip also demonstrated reduced rectus femoris activity during loading of level walking and increased gluteus maximus activity during mid-stance of decline walking.InterpretationPatients with developmental dysplasia of the hip adopt compensations both proximal and distal to the hip, which vary depending on the slope of walking. Furthering the understanding of multi-joint biomechanical compensations is important for understanding the mechanism of osteoarthritis development as well as secondary conditions.

Project description:We reviewed 38 hip replacements in 33 female patients (mean age 55.3 years) with developmental hip dysplasia. One patient had died and the remaining 32 patients (36 hips) had a mean follow-up of 12.2 years (range 8-19 years). All hips were replaced using the Müller cemented implant, and in 32 hips bulk femoral head autograft was used. In 33 hips the socket was reconstructed at the level of the true acetabulum. Complications included one intra-operative femoral fracture and two early dislocations. Correction of leg length discrepancy was possible in 30 patients. The post-operative mean modified Merle d'Aubigne and Postel scores for pain, movement and walking were 5.9, 5, and 5.3 respectively. One cup was revised due to aseptic loosening at ten years. All grafts united, but minor graft resorption was noticed in 24 hips, moderate in 2 hips and major in 1 hip.

Project description:The National Joint Registry for England and Wales (NJR) has become established as one of the largest repositories of clinical information about patients undergoing hip and knee replacement. The primary aim of this proposal is to examine the feasibility of adding value to that clinical information by partnering it with a DNA dataset to allow its use to be extended to the study of the underlying pathogenesis of diseases of the hip and knee, and the complications of their treatment. We will do this 1) by establishing a mechanism for accessing and linking pseudo-anonymised demographic and phenotype data between the NJR database and the proposed DNA Biobank; 2) by validating the collection of postal DNA samples from consenting NJR patients; and 3) by genotyping genome-wide 900 patients with the condition developmental dysplasia of the hip (DDH) to find variants that play a role in this heritable condition. The successful demonstration that the NJR can be used to establish a DNA Biobank will provide a powerful platform to examine the genetic basis for a wide range of joint diseases, and the complications of their treatment. This proposal is to carry out the genotyping portion of this project on the current CoreExome array

Project description:PurposeOur purpose was to analyze the impact of Pavlik Harness treatment on children motor skills development, comparing to a control group.MethodsA total of 121 children were included: 55 cases (children with Developmental Dysplasia of the Hip) and 66 healthy controls. Cases were recruited from 2017 to 2021 and followed up to 2022. Controls (healthy children without orthopedic pathology) were recruited from 2020 to 2022. The primary endpoint was the time of achievement of three gross motor milestones (sitting without support, hands-and-knees crawling, and walking independently).ResultsThe groups had no differences regarding sex distribution, gestational age, birth weight, and rate of twin pregnancy. The prevalence of positive family history of Development Dysplasia of the Hip (20.0% vs 3.0%, p < 0.003), breech presentation (38.2% vs 1.5%, p < 0.001), and C-section delivery (60.0% vs 19.7%, p < 0.001) was significantly higher in Development Dysplasia of the Hip group. Children with Development Dysplasia of the Hip achieved the three gross milestones evaluated 1 month later than healthy controls, although this was not statistically significant (p = 0.133 for sitting, p = 0.670 for crawling, and p = 0.499 for walking).ConclusionChildren with Development Dysplasia of the Hip, treated by Pavlik harness, do not have significant delays in motor skills acquisition.

Project description:Achondroplasia (ACH) is the most common form of hereditary dwarfism and presents with multiple musculoskeletal anomalies but is not normally associated with premature hip arthritis. Developmental dysplasia of the hip (DDH) is a spectrum of disease resulting in shallow acetabular depth and a propensity for chronic femoral subluxation or dislocation; it is among the most common causes of premature arthritis. This case report describes the diagnosis of symptomatic DDH in a patient with ACH and highlights difficulties of primary total hip arthroplasty (THA) as a treatment option. Intraoperative radiographic imaging is advised to ensure proper prosthesis placement. Femoral osteotomy may aid visualization, reduction, and avoidance of soft tissue injury. Concomitant ACH and DDH is a challenging problem that can be successfully treated with modified THA.
