Musculoskeletal models with generic and subject-specific geometry estimate different joint biomechanics in dysplastic hips.

Comput Methods Biomech Biomed Engin 2019 Jan 20:1-12. Epub 2019 Jan 20.

a Department of Mechanical Engineering and Materials Science , Washington University in St Louis , St Louis , MO , USA.

Optimizing the geometric complexity of musculoskeletal models is important for reliable yet feasible estimation of joint biomechanics. This study investigated the effects of subject-specific model geometry on hip joint reaction forces (JRFs) and muscle forces in patients with developmental dysplasia of the hip (DDH) and healthy controls. For nine DDH and nine control subjects, three models were created with increasingly subject-specific pelvis geometry, hip joint center locations and muscle attachments. Read More

Statistical shape modeling of femur shape variability in female patients with hip dysplasia.

J Orthop Res 2019 Jan 17. Epub 2019 Jan 17.

Program in Physical Therapy, Washington University School of Medicine in St. Louis, St. Louis, Missouri.

Although increasing evidence suggests that abnormal femur geometry in developmental dysplasia of the hip (DDH) may contribute to intra-articular damage and the development of hip osteoarthritis, a comprehensive 3D description of femoral abnormalities in DDH remains incomplete. Statistical shape modeling (SSM) was used to quantify three-dimensional (3D) geometric variation among femurs in female patients with DDH and control subjects. SSM correspondence points (n = 8,192) were placed on each femur using a gradient descent energy function to derive mean DDH and control femoral shapes and principal component analysis (PCA) was then used to describe shape variation.

Gonadal shield: is it the Albatross hanging around the neck of developmental dysplasia of the hip research?

J Child Orthop 2018 Dec;12(6):606-613

Department of Orthopaedics & Traumatology, Chinese University of Hong Kong, Shatin, Hong Kong.

Purpose: Prospective randomized controlled trials and long-term studies are essential future directions for building -evidence-based practices in developmental dysplasia of the hip (DDH), however, sufficient attrition in data (> 20%) can introduce bias deteriorating research quality. Pelvic radiography is synonymous with DDH assessment and so are -Gonadal Shield (GS) recommendations with pelvic radiography. -Nonetheless, losses to diagnostic information and inadequate protection have been increasingly implicated to GS usage, with significantly worse implications in female patients.

Prediction of mechanical behavior of cartilaginous infant hips in pavlik harness: A subject-specific simulation study on normal and dysplastic hips.

J Orthop Res 2019 Jan 3. Epub 2019 Jan 3.

Department of Radiology and Diagnostic Imaging, University of Alberta, 2A2.41 WMC, 8440-112 Street, Edmonton, Alberta, T6G 2B7, Canada.

In dysplastic infant hips undergoing abduction harness treatment, cartilage contact pressure is believed to have a role in therapeutic cartilage remodeling and also in the complication of femoral head avascular necrosis. To improve our understanding of the role of contact pressure in the remodeling and the complication, we modeled cartilage contact pressure in cartilaginous infant hips undergoing Pavlik harness treatment. In subject-specific finite element modeling, we simulated contact pressure of normal and dysplastic hips in Pavlik harness at 90° flexion and gravity-induced abduction angles of 40°, 60° and 80°.

Docking of the Femoral Head Following Closed Reduction for DDH: Does it Really Occur?

J Pediatr Orthop 2018 Sep;38(8):e440-e445

Division of Orthopaedic Surgery.

Background: It has been suggested that the femoral head can "dock" deeper into the acetabulum after initial closed reduction (CR) for developmental dysplasia of the hip (DDH). The purpose of this study was to quantify the interval change in femoral head position between immediate postoperative magnetic resonance imaging (MRI) and follow-up imaging at ~3 weeks.

Methods: A retrospective review of 29 patients (30 hips) who underwent CR and spica casting for DDH was conducted. Read More

Authors:
Jon R Davids

J Pediatr Orthop 2018 Jul;38 Suppl 1:S21-S27

Shriners Hospitals for Children Northern California, Sacramento, CA.

Optimal clinical decision making and surgical management of hip dysplasia in children with cerebral palsy (CP) requires an understanding of the underlying pathophysiology (pathomechanics and pathoanatomy), incidence, and natural history. The incidence of hip dysplasia in children with CP is directly related to the degree of motor impairment. A subluxated or dislocated hip in a child with CP can compromise the quality of life for both the child and their caregivers. Read More

Muscle-tendon-related abnormalities detected by ultrasonography are common in symptomatic hip dysplasia.

Arch Orthop Trauma Surg 2018 Aug 4;138(8):1059-1067. Epub 2018 May 4.

Department of Orthopaedic Surgery, Aarhus University Hospital, Tage-Hansens Gade 2, 8000, Aarhus C, Denmark.

Introduction: Hip dysplasia is characterized by reduced acetabular coverage of the femoral head leading to an increased mechanical load on the hip joint and the acting hip muscles. Potentially, the muscles and tendons functioning close to the hip joint may present with overuse-related ultrasonography findings. The primary aim was to report the prevalence of muscle-tendon-related abnormalities detected by ultrasonography in 100 patients with symptomatic hip dysplasia. Read More

A Systematic Review and Meta-analysis on the Reproducibility of Ultrasound-based Metrics for Assessing Developmental Dysplasia of the Hip.

J Pediatr Orthop 2018 Jul;38(6):e305-e311

Pediatric Orthopedics, British Columbia Children's Hospital, Vancouver, BC, Canada.

Background: The purposes of this study were to (1) perform a systematic review of articles that reported agreement or reproducibility in repeated diagnosis of developmental dysplasia of the hip (DDH) using ultrasound imaging, (2) estimate the reproducibility in the available dysplasia metrics, and (3) compare reproducibility of the available dysplasia metrics.

Methods: A systematic review of the Medline and Embase databases was performed by using a search strategy formulated from our research question: "For infants at risk of DDH, are US imaging-based diagnoses reproducible?" Two reviewers independently identified articles for inclusion in the systematic review, and then assessed the quality of the included studies using the Guidelines for Reporting Reliability and Agreement Studies guideline. Variability and agreement-related statistics in the included studies were extracted and included in a meta-analysis for summarizing the available statistics. Read More

Three-dimensional MRI Analysis of Femoral Head Remodeling After Reduction in Patients With Developmental Dysplasia of the Hip.

J Pediatr Orthop 2018 Aug;38(7):e377-e381

Department of Orthopaedic Surgery, University of Tsukuba, Tsukuba Pediatric Orthopaedic Group, Tsukuba.

Background: Previous reports on patients with developmental dysplasia of the hip (DDH) showed that the prereduced femoral head was notably smaller and more nonspherical than the intact head, with growth failure observed at the proximal posteromedial area. We evaluated the shape of the femoral head cartilage in patients with DDH before and after reduction, with size and sphericity assessed using 3-dimensional (3D) magnetic resonance imaging (MRI).

Methods: We studied 10 patients with unilateral DDH (all female) who underwent closed reduction. Read More

The anteroposterior axis of the tibia is adjusted to approximately a right angle to the anterior pelvic plane in the standing position in patients with hip dysplasia similar to normal subjects: a cross-sectional study.

J Orthop Surg Res 2018 May 2;13(1):105. Epub 2018 May 2.

Department of Orthopedic Surgery, Niigata University Medical and Dental Hospital, Niigata, 9518510, Japan.

Background: We previously described that the anteroposterior (AP) axis of the tibia is approximately perpendicular to the transverse axis of the anterior pelvic plane (APP) in the standing position in healthy subjects. The purpose of this study was to investigate the rotational alignment between the APP and clinical epicondylar axis and the AP axis of the tibia relative to pelvic coordination in the standing position in normal subjects and in women with developmental dysplasia of the hip (DDH) to aid decision making for surgeons in the alignment of implants in total hip or knee arthroplasty.

Methods: This study included 77 Japanese women. Read More
