An artificially-intelligent biomeasurement system for total hip arthroplasty patient rehabilitation.
… range of movement (ROM) of the replacement hip joint in total hip arthroplasty (THA) patients. In so doing, the following original work is presented: Production of a wearable, microcontroller-equipped system which was able to wirelessly relay accelerometer sensor data of the subjects key …

In Vivo Wear Performance of Highly-crosslinked Polyethylene in Total Hip Arthroplasty
… (HXLPE) has been a major advancement in total hip arthroplasty (THA), significantly reducing wear rates and the need for revisions compared to conventional ultra-high molecular weight polyethylene. However, volumetric wear and the associated periprosthetic tissue response remain one of …

Development of clinical assessment strategies for patients undergoing total hip arthroplasty (THA)
Total hip arthroplasty (THA) is a common surgery that people suffering from hip pain and reduced mobility, generally caused by osteoartrhosis, undergo. In the surgery the head and neck of the femur bone are replaced with a prosthesis whose ball-like head fits into a cup that is inserted into the …

Dislocation Mechanics of Total Hip Arthroplasty: A Combined Experimental and Computational Analysis
<p>While total hip arthroplasty is considered a successful procedure, dislocation remains a serious complication as recurrent dislocations may require additional surgeries. Knowledge on dislocation events as they occur in vivo are limited, therefore researchers rely on experimental and …

A Virtual Method for Establishing Femoral Stem Position in Total Hip Arthroplasty
<p>Total hip arthroplasty (THA) is one of the most successful orthopedic surgeries performed, in which the hip joint is reconstructed to improve functionality and decrease pain in the joint. Despite the success of these procedures, femoral stem misalignment remains an area that influences THA …

Displaced intracapsular neck of femur fractures: dislocation rate after total hip arthroplasty
… common orthopaedic complications after primary total hip arthroplasty (THA). The reported dislocation rate in elective THR is 5 - 8%. This number increases up to 22% for THA done for neck of femur fractures. Larger femoral head sizes increase the head-neck ratio and range of motion before …

Functional Recovery After Elective Total Hip Arthroplasty Due to Osteoarthritis: The Role of Postural Stability
… months. Balance confidence, quality of life, hip function, stiffness and pain, physical activity, and overall health recovered similarly across approaches over the first three months after THA surgery. Study 3 surveyed Canadian physical therapists to characterize early postoperative …

The Effects and Analysis of Implant Type and Surgical Approach in Total Hip Arthroplasty Dislocation Resistance
<p>Total hip arthroplasty (THA) is one of the most successful orthopaedic surgeries performed, in which the hip joint is reconstructed to decrease pain and to improve the functionality to the joint. Although these surgeries are very successful, there still remain areas for improvement, such as …

An exploration into young patients’ (≤ 50 years) expectations following primary total hip arthroplasty; An Interpretative Phenomenological Analysis study.
Title: YOUNG HIP: An exploration into young patients’ (<50 years) expectations following primary total hip arthroplasty: An Interpretative Phenomenological Analysis study. Introduction. Total hip replacements (THR) are common operations performed in orthopaedics. Though initially developed to …

Radiological features of femoroacetabular impingement in patients undergoing hip resurfacing arthroplasty and total hip arthroplasty for osteoarthritis of the hip
Osteoarthritis of the hip is a common condition which in its later stages often requires arthroplasty surgery. The principle operations performed for late stage osteoarthritis are the Birmingham Hip Resurfacing (BHR) and Total Hip replacement (THR), which require implants that have been through …

Automated determination of the theoretical range of hip motion prior to total hip arthroplasty using 3D models created from pelvic CT scans
One of the major concerns following a total hip arthroplasty (THA) is the risk of dislocation: the artificial femoral head pops out of the replaced acetabulum due to a leverage effect. It affects about 4,000 patients a year in the UK, for 80,000 THA1. To prevent this complication, surgeons would …

Numerical optimisation of biomedical implant characteristics for increased service life.
… stress shielding which in turn could increase Total Hip Arthroplasty (THA) service life and reduce patient discomfort by employing a distributed stiffness along implant length. Research found that through distributing stiffness along THA stem length, significant reductions in stress shielding …

The suitability of biodegradable poly(dl-lactide-co-glycolide)75:25 microspheres for the sustained release of antibiotics
Post-operative infections resulting from total hip arthroplasty are caused by bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa entering the wound perioperatively or by haemetogenous spread from distant loci of infection. They can endanger patient health and require expensive …

An articulated drill and hybrid tracking navigation system for orthopaedic surgery
… of the THA procedure. Besides that, after the total hip arthroplasty (THA) procedure, there is also probability of the patient ending up with unequal leg lengths, which are referred to as a leg-length discrepancy (LLD). One way to reduce the risk in THA procedure is improving accurate placement …
