OBJECTIVES:  Comparison of PennHIP and a novel method to diagnose hip laxity, called the Vezzoni modified Badertscher distension device technique. METHODS:  In a total of 10 dogs, it was first assessed whether the distraction index (DI) from the PennHIP evaluation center could be reproduced by two individual observers. In the next two steps, the DI measurements made by the individual observers and the PennHIP evaluation center were compared with the laxity index (LI) measured on the Vezzoni modified Badertscher distension device view...

BACKGROUND: Total hip arthroplasty is one of the most commonly performed surgical procedures worldwide. There are a number of surgical approaches for total hip arthroplasty and no high-level evidence supporting one approach over the other. Each approach has its unique benefits and drawbacks. This trial aims to directly compare the three most common surgical approaches for total hip arthroplasty. METHODS/DESIGN: This is a single-centre study conducted at Western Health, Melbourne, Australia; a large metropolitan centre...

Background: Although the developmental dysplasia of the hip (DDH) is well known to pediatric orthopedists, its etiology has still remained unknown and despite dedication of a vast majority of research, the results are still inadequate and confusing. The exact incidence of DDH and its relationship with known risk factors in Iran is still unknown. Here we represent the results of one year study on the incidence and related conditions of DDH. Methods: Sonography was performed on the hip joints of 1073 full term healthy newborns at Imam Khomeini Hospital from March 2013 to March 2014...

BACKGROUND: We argue that 1-stage bilaterally total hip arthroplasty (THA) could be acceptable in bilateral coxarthrosis because of high-riding developmental dysplasia of the hip (DDH). METHODS: Sixty-nine cases (51 patients) of high-riding DDH in patients who underwent THA from 2010 to 2013 were reviewed. Patients were divided into 2 groups: unilateral (group 1) and 1-stage bilateral surgery (group 2). The clinical measurements were the visual analog scale and Harris Hip Score...

PURPOSE: To investigate the arthroscopic pathoanatomy of the transverse acetabular ligament (TAL) and determine whether a TAL incision is necessary for the concentric reduction of developmental dysplasia of the hip (DDH) in infants and young children. METHODS: We retrospectively reviewed patients who underwent arthroscopic-assisted reduction for DDH between July 2008 and April 2016. The indications for this intervention included patients in whom closed reduction failed and those who did not require bone operations...

PURPOSE: Our objective was to find the best predictor of late residual acetabular dysplasia in developmental dysplasia of the hip (DDH) after closed reduction (CR) and discuss the indications for secondary surgery. METHODS: We retrospectively reviewed the records of 89 patients with DDH (mean age 16.1 ± 4.6 months; 99 hips) who were treated by CR. Hips were divided into three groups according to final outcomes: satisfactory, unsatisfactory and operation. The changes in the acetabular index (AI), centre-edge angle of Wiberg (CEA), Reimer's index (RI) and centre-head distance discrepancy (CHDD) over time among groups were compared...

BACKGROUND: Tears of the Ligamentum Teres are a common cause of groin pain. Tears of the ligament frequently co-exist alongside other bony or labral intra-articular hip lesions, which are also treated at the time of arthroscopy. For this reason, it is often difficult to assess the effect that debridement alone has on improving patient pain and function. This study aims to assess the short-term outcomes of arthroscopic debridement of isolated Ligamentum Teres tears using a validated patient-reported outcome score - the International Hip Outcome Tool (iHOT-33)...

BACKGROUND: Multiple Ephiphyseal Dysplasia (MED) is a rare autosomal dominant skeletal dysplasia that causes deformation of the epiphysis of the involved joints. The hips are invariably affected and symptoms due to incapacitating early onset degenerative hip disease often begin between the second and fourth decade of life. Literature regarding the clinical and radiographical outcomes after total hip arthroplasty in this young population are very scarce. HYPOTHESIS: In patients with multiple epiphyseal dysplasia and early onset degenerative hip disease, hybrid total hip arthroplasty is a safe and reliable procedure...

Background Patients with developmental dysplasia of the hip (DDH) may have decreased blood supply to the femoral heads. Finding a non-invasive method to evaluate whether the femoral heads in patients with DDH are ischemic is paramount for orthopedic surgeons. Purpose To identify whether parameters reflecting perfusion and diffusion in intravoxel incoherent motion (IVIM) sequences can be used to assess ischemia in femoral heads in patients with DDH after closed reduction. Material and Methods Twenty-eight patients with DDH who had undergone closed reduction were enrolled...

Hip problems due to dysplasia are commonly associated with female athletes in sports demanding supraphysiologic motion, such as ballet, gymnastics and figure skating. However, hip problems are rarely mentioned among wrestlers, a male sport in which flexibility is advantageous. Dysplasia may have a mostly unrecognized prevalence among wrestlers that can lead to problems and benefit from reorientation periacetabular osteotomy (PAO). Study design in this research is Level 4 evidence case reports. Three consecutive intercollegiate wrestlers ages 20, 21 and 22 years underwent PAO for dysplasia and are reported...

Limited research exists on the possible association between duration of symptoms and clinical outcomes following hip arthroscopy for labral tears. The purpose of this study was to evaluate whether duration of symptoms affected clinical and patient-reported outcome (PRO) scores following hip arthroscopy for labral tears. From 2008 to 2011, data were collected prospectively on all patients undergoing primary hip arthroscopy for labral tears. Workers' compensation cases, dysplasia cases and patients with previous ipsilateral hip surgeries were excluded...

Redirective, periacetabular osteotomies (PAO) represent a group of surgical procedures for treatment of developmental dysplasia of the hip (DDH) in skeletally mature and immature patients. The ultimate goal of all procedures is to reduce symptoms, improve function and delay or prevent progression of osteoarthritis. During the last two decades, the understanding of the underlying pathomechanisms has continuously evolved. This is mainly attributable to the development of the femoroacetabular impingement concept that has increased the awareness of the underlying three-dimensional complexity associated with DDH...

CASE: A large surgical correction was required for severe hip dysplasia, which was associated with a delayed-onset sciatic nerve injury in an adolescent patient. A cortical bone spur on the outside of the acetabular fragment produced an indirect injury that became symptomatic during mobilization of the patient. CONCLUSION: The risk of direct injury to the sciatic nerve during a periacetabular osteotomy is quite low when the osteotomy is executed in extension with abduction of the hip and flexion of the knee to reduce tension on the sciatic nerve...

PURPOSE: In total hip arthroplasty, prediction of the optimal implant size is important in order to prevent perioperative complications. However, it is not easy to achieve complete agreement between the planned size and the actual size required appropriate implant fit. No previous report has adequately discussed the factors related to mismatch between predicted and actual implant sizes. The purpose was to report the results of a single surgeon case series of patients undergoing THA using computed tomography (CT)-based templating and the possible factors related to implant size mismatch...

Spondyloepimetaphyseal dysplasia with joint laxity type 1 (SEMDJL1) is a rare entity with a recessive inheritance. In this report, we describe 3 affected members of the same family who present with short stature, hyperlaxity with secondary spinal malalignment, ulnar subluxation, developmental dysplasia of the hips, and craniofacial alterations; one member also had learning difficulties. DNA analysis showed compound heterozygous variants in the B3GALT6 gene (c.901_921dup, c.511C>T) in all 3 patients, inherited from the parents...

Developmental dysplasia of the hip (DDH) in humans is a common condition that is associated with hip pain, functional limitations, and secondary osteoarthritis (OA). Surgical treatment of DDH has improved in the last decade, allowing excellent outcomes at short- and mid-term follow-up. Still, the etiology, mechanobiology, and pathology underlying this disease are not well understood. A pre-clinical animal model of DDH could help advance the field with a deeper understanding of specific pathways that initiate hip joint degeneration secondary to abnormal biomechanics...

Canine hip and elbow dysplasia are major orthopaedic problems prevalent the world over, and South Africa is no exception. Hip and elbow dysplasia phenotypic status is certified by a number of different radiographic schemes in the world. South Africa uses the Fédération Cynologique Internationale system to certify hips, and the International Elbow Working Group scheme to certify elbows. One way of reducing these often crippling conditions is by selective breeding using only dogs with no or marginal dysplastic joints...

PURPOSE: Curved periacetabular osteotomy (CPO) has been developed for the treatment of acetabular dysplasia. While several studies have reported its good clinical results, the complications of CPO include delayed union and nonunion of the superior pubic ramus. The purpose of this study is to investigate the prevalence of delayed union of the pubis one year after CPO, and to determine the risk factors for this complication. METHODS: The study examined 113 hips that underwent CPO between 2008 and 2012...
