Filter by:The incidence of primary hip joint prosthesis is 180 per. 100,000 inhabitants. In male patients younger than 50 years the 10-years survival of the prosthesis is 89 % and 82 % over 15 years. In women younger than 50 years the 10-years survival of the prosthesis is 87 % and 78 % over 15 years. As revision surgery is associated with higher complication risk for the patient and poorer out-come and implant survival it is necessary to examine possible methods that may increase long-term survival of the primary hip prosthesis or facilitate better outcomes after revision of hip joint prostheses for younger patients. In younger patients the prosthesis often is inserted without the use of cement. When not using cement, it is crucial for the final result, that there is a direct bone ingrowth of the prosthesis. The chance of getting bone ingrowth depends firstly on a good immediate mechanical fixation at surgery and secondly on osteoconductive abilities of the prosthetic surface. This study investigates a new bone sparing implant with a new surface compared to a conventional implant.
The aim of the study is to understand the effect of spinal deformity and altered sagittal plane parameters of lumbosacral complex on acetabular cup position in THA.
The development of minimal-incision techniques for total hip arthroplasty (THA) with preservation of soft tissue is generally associated with reduction of postoperative pain and increased patient comfort. Although this technique requires a smaller incision than other approaches used for hip surgery, adequate postoperative pain management remains crucial for enhanced recovery and early rehabilitation. The fascia iliaca block (FIB) is commonly used to enhance analgesia after hip replacement surgery, however the effect of FIB volume on analgesia quality and sensory-motor blockade have not been adequately studied. In this study, total postsurgical opioid consumption (morphine equivalents IV in hospital and oral at home) through the first postoperative week will be compared and extent and duration of sensory motor block through the 2-day inpatient stay will be evaluated.
Total Hip Arthroplasty (THA) is one of the most commonly performed orthopaedic operations worldwide. The main aim is overall improvement in levels of patient pain and mobility. Such surgery involves implantation of both an acetabular and femoral component. With the patient in the lateral decubitus position, the Orthopaedic Surgeon assumes that the pelvis is in a neutral position with respect to all three body planes at the time of acetabular component implantation. With regard to THA, the current orthopaedic literature demonstrates a clear relationship between acetabular component positioning, polyethylene wear and risk of dislocation. Problems with edge loading, stripe wear and squeaking are also associated with higher acetabular inclination angles, particularly in hard-on-hard bearing implants. The important parameters of acetabular component positioning are depth, height, version and inclination. Control of acetabular component inclination, particularly in the lateral decubitus position, is difficult and remains a challenge for the Orthopaedic Surgeon. Accurate implantation of the acetabular component within the 'safe zone' of radiological inclination is dependent on: - Operative version - Operative inclination - Pelvic position (Primarily, but not exclusively, abduction / adduction.) This study aims to investigate the effect of patient pelvic positioning and method of acetabular component insertion on acetabular component inclination during Total Hip Arthroplasty (THA).
