BACKGROUND: Taper corrosion at the modular junctions of total hip arthroplasty (THA) femoral stems are known to cause locally destructive adverse local tissue reaction (ALTR). However, the implants at risk remain to be fully elucidated. CASE REVIEW: We report the case of a 76-year-old woman with hip pain, abductor weakness, and sciatic nerve symptoms 2 years following metal-on-polyethylene THA. Serum cobalt levels were elevated, while chromium levels were normal...

BACKGROUND: Culture negative prosthetic joint infections (PJI) still remain an issue even with the advantages of the new diagnostic tools for PJI. This is why some orthopedic surgeons have reservations relative to the use of preoperative antibiotic prophylaxis when a PJI is suspected. The purpose of the present study was to evaluate the influence of preoperative antibiotic prophylaxis on intraoperative cultures. MATERIAL AND METHODS: An enhanced diagnostic protocol for PJI (Zimmerli criteria) was used for the inclusion criteria in order to collect all PJI that were seen in a university hospital...

BACKGROUND: Staged revision for periprosthetic infection of the hip is an accepted and widely used technique by many surgeons. However, single-stage exchange of the hip prosthesis remains an attractive option to others because of the advantages of reduced morbidity, shorter treatment time and hospital stay in addition to the reduced cost of treatment. HYPOTHESIS: Single-stage revision for periprosthetic hip infection can achieve excellent results if a specific protocol for patients' selection and management is followed...

INTRODUCTION: Proximal plate fixation in periprosthetic femur fractures can be improved by plate anchorage in the greater trochanter (lateral tension band principle) or bicortical locking screw placement beside the prosthesis stem in an embracement configuration. Both concepts were compared in a biomechanical test using a femoral hook plate (hook) or a locking attachment plate (LAP). METHODS: After bone mineral density (BMD) measurement in the greater trochanter, six pairs of fresh frozen human femora were assigned to two groups and instrumented with cemented hip endoprostheses...

INTRODUCTION: The presence of postoperative seromadesis is common, corresponding to the presence of serum in the subcutaneous tissue post a surgical event. Erythromycin has been reported as sclerosing, although not in orthopedic surgery. We report a case of erythromycin seromadesis in orthopedic surgery. CASE PRESENTATION: We present a case of a 63-year-old woman having undergone femoral prosthesis surgery and total hip replacement with a subfacial seroma without findings of infection, refractory to standard treatment of compression bandages, massage and cleaning surgery in two oportunities...

INTRODUCTION: The everyday life of a non-ambulatory adolescent or young adult with cerebral palsy can be severely impaired by a painful or stiff hip. The usual surgical solutions such as proximal femoral resection (PFR) are not entirely satisfactory for pain relief, and are mutilating. HYPOTHESIS: A retrospective study assessed the impact of total hip replacement (THR) on such impairment, on the hypothesis that it is more effective than PFR in relieving pain, without aggravating disability...

Hip arthroplasty is commonly performed on patients with debilitating hip disease to relieve symptoms and improve quality of life. Generally, long-term success rates are excellent. However, a subset of patients requires revision due to prosthesis failure. A wide array of microscopic findings can be seen in surrounding tissues and many of the findings are etiologically nonspecific. The aim of this review is to discuss the etiologies and accompanying adverse tissue reactions seen with prosthesis failure, including the findings seen in aseptic lymphocyte-dominated vasculitis-associated lesion...

INTRODUCTION: Total hip replacement is a successful procedure with long survival records compared to other joint arthroplasties. Cemented implants have been available for many years, however the complications associated with loosening and, ultimately, failure over time has led to the development of cementless stems and implants.The ideal prosthesis should recreate a biomechanically normal hip joint, allow pain-free function and last the patient's life span without requiring revision. Optimal results with uncemented femoral stems rely on obtaining initial stability, osseointegration, biological fixation, and uniform stress transfer to the proximal bone...

Sloped walking requires altered strategies for maintaining dynamic balance relative to level-ground walking, as evidenced by changes in sagittal-plane whole-body angular momentum (H) in able-bodied individuals. The ankle plantarflexor muscles are critical for regulating H, and functional loss of these muscles from transtibial amputation affects this regulation. However, it is unclear if a powered prosthesis, which more closely emulates intact ankle function than a passive energy-storage-and-return prosthesis, affects H differently during sloped walking...

BACKGROUND: A head that is "clinically cold welded" to a stem is one of the commonest reasons for unplanned removal of the stem. It is not clear which hip designs are at greatest risk of clinical cold welding. METHODS: This was a case-control study of consecutively received hip implant retrievals; we chose the design of hip that had the greatest number of truly cold-welded heads (n = 11). For our controls, we chose retrieved hips of the same design but without cold welding of the head (n = 35)...
