BACKGROUND: Periacetabular osteotomy (PAO) is an established treatment for symptomatic acetabular dysplasia, which is a well-recognized cause of hip pain, functional limitations, and secondary osteoarthritis. The purpose of this study was to describe the demographics of patients undergoing PAO, the baseline patient-reported outcome measures for this population, and the types of adjunctive procedures performed at the time of PAO surgery. METHODS: Demographics, disease characteristics, and patient-reported functional measures were prospectively collected from all patients who underwent PAO performed by 12 surgeons from 2008 to 2013...

BACKGROUND: Developmental dysplasia of the hip is effectively treated with a Pavlik harness (PH) within the first 6 months of life. Over 80% of unstable hips in the newborn period will naturally stabilize by 2 months of age. If there is no difference in the effectiveness of initiating PH treatment at 1 week compared with 4 weeks of age, waiting may allow the hips to naturally stabilize and avoid treatment. The purpose of this study is to evaluate whether the timing of PH implementation influences its effectiveness in the treatment of developmental dysplasia of the hip...

The purpose was to examine the effects of a standard treatment (ST) walking program compared to a ST walking program enhanced (Enhanced Treatment, ET) on cardiovascular health outcomes among Korean-Chinese female migrant workers in Korea. A quasi-experimental sequential design was used. A total of 132 Korean-Chinese women without contraindications to physical activity participated in the study. Both ST and ET groups had monthly goal settings and the ET group received text messages to encourage walking adherence and acculturation...

Metal-on-metal (MOM) hip resurfacing has recently been a popular prosthesis choice for the treatment of symptomatic arthritis, but results in the release of cobalt and chromium ions into the circulation that can be associated with adverse clinical effects. The mechanism underlying these effects remains unclear. While chromosomal aneuploidy and translocations are associated with this exposure, the presence of subtle structural epigenetic modifications in patients with MOM joint-replacements remains unexplored...

Background and purpose - Telemedicine could allow patients to be discharged more quickly after surgery and contribute to improve fast-track procedures without compromising quality, patient safety, functionality, anxiety, or other patient-perceived parameters. We investigated whether using telemedicine support (TMS) would permit hospital discharge after 1 day without loss of self-assessed quality of life, loss of functionality, increased anxiety, increased rates of re-admission, or increased rates of complications after hip replacement...

OBJECTIVE: In this study, we set out to investigate the relationship between angiotensin-converting enzyme ( ACE) I/D polymorphism, serum ACE activity and bone mineral density (BMD) in older Chinese. METHODS: A standardized, structured, face-to-face interview was performed to collect demographic information. BMD was measured using dual-energy X-ray absorptiometry (DXA). I/D genotypes of ACE were determined by polymerase chain reaction (PCR) amplification. Serum ACE activity was determined photometrically by a commercially available kinetic kit...

BACKGROUND: Hip fractures cause increased mortality and disability and consume enormous healthcare resources. Only 46% of hip fracture patients have osteoporosis at the total hip according to dual-energy X-ray absorptiometry (DXA) measurement. Cortical porosity increases with ageing and is believed to be important for bone strength. OBJECTIVE: To investigate whether older women with hip fracture have higher cortical porosity than controls, and if so whether this difference is independent of clinical risk factors and areal bone mineral density (aBMD)...

The iliopsoas of the rat is composed of two muscles - the psoas major muscle and the iliacus muscle. The psoas major muscle arises from all the lumbar vertebrae and the iliacus muscle from the fifth and sixth lumbar vertebrae and ilium. Their common insertion point is the lesser trochanter of the femur, and their common action is the lateral rotation of the femur and flexion of the hip joint. Unlike humans, the rat is a quadruped and only occasionally rises up on its hind legs. Therefore, it is expected that the fibre type composition of the rat iliopsoas muscle will be different than that of humans...

The dual mobility cup (DMC) is an increasingly important tool not only in primary but also in revision total hip arthroplasty to prevent dislocation and eventually reduce postoperative complication rates. Various studies have shown survival rates with DMCs of up to 100% with an average dislocation rate of less than 1.5% after primary hip arthroplasty and a follow-up of 10 years. In revision surgery, survival rates of up to 99% were reported with dislocation rates between 0 and 10% after an average of 5 years after implantation...

Correct component placement is of significant importance to ensure optimal outcomes in total hip arthroplasty (THA). Traditionally, the Lewinnek plane has been referenced as an adequate "safe zone", formed between the anterior superior iliac spines and public tubercles to optimize acetabular orientation. However, recent evidence shows that the positioning of this plane may vary due to the biomechanical relationship between the lumbar spine and hip. Therefore, the plane acquired intraoperatively may not accurately recreate the actual functional plane and acetabular orientation encountered outside of the intraoperative environment...

BACKGROUND: Lateral interbody cages have been proven useful in spinal fusions. Spanning both lateral cortical rims while sparing the Anterior Longitudinal Ligament, the lateral interbody cages restore and maintain disc height while adding stability prior to supplemental fixation. The standard approach for their insertion is by a 90-degree lateral transpsoas method. This is relatively bloodless compared to other techniques although has its limitations, requiring neuro-monitoring and being, at times, very difficult at L4/5 due to iliac crest obstruction or an anterior plexus position...

In 1960s, toxic heart failure due to cobalt poisoning was firstly reported from Canadian industrial worker. Following development of bearing materials in hip arthroplasties, using cobalt-chrome alloy in bearing surface, there were rarely reported of systemic affect toxic cobaltism include toxic heart failure due to articulation wear in Western countries. It could be happened more easily by third body wear from ceramic particle especially revision total hip replacement (THR) surgery using cobalt-chrome alloy following ceramic articulation breakage which index surgery performed by ceramic on ceramic bearing...

Periprosthetic joint infection (PJI) of the hip can be difficult to treat and can lead to a number of problems including: i) severe functional decline of the hip joint and ii) increasing financial burden for patients due to long treatment periods and the need for repeated surgical interventions. Because there is risk of inadequate control of infection or relapse of a preexisting infection following the treatment of PJI through surgery, it is important to closely observe clinical symptoms such as systemic fever...

A case of a female patient with local and systemic complications of metallosis, following catastrophic wear of a revised hip arthroplasty, is presented. The patient had a history of a fractured ceramic-on-ceramic implant, exchanged with a metal-on-polyethylene prosthesis. Systemic complications included sarcoidosis-like reactions, presenting as granulomatous lung disease, along with chorioretinitis, erythema nodosum, and cardiomyopathy. High local and circulating cobalt and chromium levels established the diagnosis...

Idiopathic chondrolysis of the hip usually develops in adolescents and is a disease characterized by gradual degenerative changes of the hyaline cartilage surrounding the head of the femur. It eventually decreases the hip joint space and causes limitations in the hip joint range of motion due to pain. The authors had experienced an unusual case of bilateral idiopathic chondrolysis of the hip in an 54 year-old male; thus, we report the treatment results and literature reviews in this case report.
