INTRODUCTION: Gait analysis is one of the poorly understood dimensions of the functional results obtained after periacetabular osteotomy (PAO) due to dysplasia of the hip. MATERIALS AND METHODS: Spatiotemporal parameters as well as coronal and sagittal plane kinematics and moments were compared among three demographically similar groups of subjects: (i) 23 patients with excellent results according to the Harris Hip Score (HHS) (mean 6.6 years of follow-up); (ii) 12 patients with good and fair results according to the HHS (mean 9...

BACKGROUND: Total hip arthroplasty (THA) is a common procedure used to treat bony hip deformities and skeletal dysplasia in dwarfism. These surgeries are often more difficult than conventional THA as they may involve malformed joints and poor bone quality, and may require smaller prostheses. This study aims to investigate whether implant survivorship and revision rates vary among patients with and without dwarfism undergoing THA. METHODS: A retrospective case-control study was performed for 102 THAs completed between 1997 and 2014 in patients under the height threshold of 147...

METHODS: 40 healthy mixed-breed dogs were randomly divided into 2 groups, arterial ischaemia (AI) and venous congestion (VC), each containing 20 dogs. The dogs underwent a procedure where the deep femoral artery or deep femoral vein was ligated randomly on the left or right side to establish the femoral head osteonecrosis model. 13 dogs from each group, AI and VC, were randomly selected for subsequent study. 3 dogs were randomly chosen from each group to receive core decompression (CD) every 2 weeks for a total of 4 sessions...

INTRODUCTION: In the United Kingdom, over 83,000 primary total hip arthroplasties (THAs) were performed last year, of which 20% are in patients under the age of 60 years. These patients generally have a longer life expectancy and a higher activity level than an older cohort, which may potentially translate to higher revision rates. METHODS: We reviewed our Trent regional arthroplasty register to assess current surgical practice in younger patients undergoing total hip arthroplasty...

Developmental dysplasia of the hip (DDH) is the commonest 'congenital' disease of the locomotor system throughout the world. According to the World Health Organisation (WHO) Bone & Joint Decade (2000-2010) 10%-15% of patients who are under the age of 50 when they require a hip replacement do so because of infant hip dysplasia.The background; technique and common mistakes; results; debate and politics; and the challenges of infant hip sonography are reviewed.

The terminology of the wide spectrum of hip deformities seen during the neonatal, infantile and adult life period remains controversial, mainly due to the indiscriminate use of the terms dysplasia, subluxation, congenital hip disease, developmental hip disease, congenital dislocation, etc. This has a serious implication on the anticipation of clinical outcomes, complications and comparison of different reconstructive techniques when these patients are treated with total hip arthroplasty in adulthood. Journals, specialising in this field, should publish homogeneous series (type of the disease, reconstruction technique, implants) in order to clarify arguments and anticipate clinical outcomes...

INTRODUCTION: The objectives were to evaluate a technique, outcome and complications following anterior greater trochanteric with gluteus medius muscle pedicle bone graft (AMG) procedure in the treatment of adolescent and active adult hip disorders. METHODS: 20 patients (20 hips) with a mean age of 22.7 ± 15.6 (range 10.0-63.5) years who had undergone AMG and been followed up more than 12 months postoperative were retrospectively enrolled in our study. The AMG procedure was performed in conjunction with subcapital osteotomy for slipped capital femoral epiphysis in 12 and open reduction for fracture/dislocation in 8 hips...

With metal-on-metal (MoM) bearings, fluid film lubrication is disrupted when the contact patch area between the femoral head and the cup is close to the edge of the acetabular component, making the calculation of the contact patch to rim (CPR) distance a key variable in the study of the performance of MoM bearings. A few research centers have used models of varying complexity to calculate the CPR distance and determine its relationship with assessments of component wear. In this review, we aimed to summarise the current knowledge related to the application of CPR distance calculations in the study of in vivo performance of MoM bearings...

BACKGROUND: Metal-on-metal hip resurfacing (MoMHR) has been proposed as an effective surgical treatment for young and active patients with symptomatic hip disease. Recently, good clinical and radiographic outcomes have been reported by the designer surgeons at a 15.3 years follow-up; however, results at long follow-up by non-designer surgeons are less satisfactory. The aim of the study was to investigate if MoMHR can produce satisfactory clinical and radiographic results and if survival rate can be high even if the procedure is performed by non-designer surgeons...

PURPOSE: To report 3 patients operated on using medial hip arthroscopic portals, describe the surgical technique and clinical outcomes. METHODS: Three medial portals were made, the first one at the posterior edge of the adductor longus muscle (posterior medial portal), the second one at the anterior (anterior medial portal) and the third at the posterior border of the adductor longus, 5 cm distal to the inguinal crease (distal posterior medial portal). The first case was an 8-year-old boy with a lytic lesion at the posteromedial region of the femoral neck suggestive of sub-acute osteomyelitis...

PURPOSE: To compare the acetabular component size relative to the patient's native femoral head size between conventional THA (CTHA) approach and robotic-arm assisted THA (RTHA) to infer which of these techniques preserved more acetabular bone. METHODS: Patients were included if they had primary osteoarthritis (OA) and underwent total hip replacement between June 2008 and March 2014. Patients were excluded if they had missing or rotated postoperative anteroposterior radiographs...

The snapping hip (SH) syndrome is characterised by an audible snapping, often accompanied by pain, which usually occurs with the flexion and extension of the hip during exercise or ordinary daily activities.The causes of SH can be classified as external, internal and intraarticular. The prevalence of asymptomatic SH in the population is unknown and the incidence of symptomatic cases is not well-defined. The painless snapping in the hip is common in the general population; the symptomatic SH with debilitating pain and weakness is often seen in those who take part in activities such as ballet and running hurdles...

INTRODUCTION: The Sparing Piriformis and Internus, Repair Externus (SPAIRE) technique allows a muscle sparing mini-posterior approach to the hip. METHOD: We present in this article a description of an adaptation of the familiar posterior approach (PA) in which the only tendon released is obturator externus. Termed SPAIRE, this muscle sparing technique enables preservation of the piriformis tendon and conjoint insertion of obturator internus and the gemelli. The technical description allows for safe and reliable replication by any surgeon familiar with the posterior approach (PA) to the hip without reliance on additional equipment, and without compromising the ability to convert into a more extensile approach...

BACKGROUND: Determining the aetiology of persistent pain following total hip arthroplasty (THA) can be challenging. Impingement of the iliopsoas muscle due to a malpositioned acetabular component after THA might be a potential cause of postoperative groin pain. METHODS: We retrospectively analysed the data of 12 consecutive patients from our orthopaedic department who underwent cup revision for painful iliopsoas impingement after primary THA. RESULTS: Thorough physical examination as well as radiological assessment of the included patients revealed that malpositioning of the acetabular component provoked iliopsoas impingement...

Patients presenting with skeletal metastatic lesions requiring surgery are increasing, this is due to an ageing population and improved oncological survival following advances in medical management. Furthermore, patients are living longer with skeletal metastatic disease. The majority of bone metastases occur in the proximal femur. Robust diagnosis (Biopsy) and treatment is required to ensure that patients can mobilise fully weight bearing immediately post-surgery and that the construct should outlive the patients expected survival...

PURPOSE: Numerous salvage surgeries were popularised to halt the progression of hip osteonecrosis (ON). We aimed to compare the clinico-radiological outcomes of inverted femoral head graft (IFHG) versus standard core decompression (SCD) in treatment of nontraumatic hip ON at pre-arthritic stage. METHODS: A case review was performed at a minimum 3 years follow-up of 61 patients (71 hips; mean age 32.96 (19-50) years; mean follow-up 7.86 (3-14) years; mean body mass index 28...

BACKGROUND: Concerns arise over the early complications encountered during the learning curve for the direct anterior approach for total hip arthroplasty. PURPOSE: The purpose of this study is to examine the learning experience of a single surgeon in adapting this approach. METHODS: The 1st 500 primary total hip arthroplasties are reviewed. The patients were evaluated out to 3 months. Rates of major complications, reoperations, periprosthetic fractures, heterotopic ossification, leg length discrepancies and lateral femoral cutaneous nerve deficits were identified for each of 100 patients...

PURPOSE: Bone preservation is an important advantage of the resurfacing hip arthroplasty (RHA) concept. We hypothesised that patients' increase in physical activity level after RHA would positively relate with periprosthetic bone mineral density (BMD) changes and thus facilitate bone preservation. METHODS: BMD-changes were prospectively recorded in 38 patients after RHA. Dual-energy absorptiometry was used to quantify BMD-changes in 6 periprosthetic regions of interest preoperatively, at 6 months, 1, 2 and 3 years postoperative...

BACKGROUND: Rigid and safe transacetabular screw fixation in total hip arthroplasty (THA) is achieved by pursuing deeper bone stock and avoiding injuries to the neurovascular structures, but these efforts can be restricted by the distribution of screw-holes on cups by the manufacturer. We therefore tried to determine: (i) optimal screw-hole positions on cups to allow anatomical placement of screws; (ii) rationality of the basic 3-screw-hole cluster on commercial cups; and (iii) the optimum method for placing commercial cups in accordance with acetabular anatomy...
