1/101. Conversion of hip arthrodesis to total joint arthroplasty.Conversion of a hip arthrodesis to a total joint arthroplasty is an uncommon procedure compared to the standard or revision total hip replacement. In this report, two illustrative cases are presented in which conversion to a total joint arthroplasty was performed, and a review of the literature for indications, complications, contraindications, and outcomes of this procedure is provided.- - - - - - - - - - ranking = 1keywords = hip (Clic here for more details about this article) |
2/101. Intrahepatic hemorrhage after use of low-molecular-weight heparin for total hip arthroplasty.Low-molecular-weight heparin (LMWH) has become a popular agent for prophylaxis against deep vein thrombosis and thromboembolic disease after total joint arthroplasty. LMWH allows for consistent dosing in postoperative patients without the need for laboratory monitoring. hemorrhage is an uncommon but documented adverse reaction when using LMWH; however, intrahepatic hemorrhage has not been previously reported in conjunction with LMWH therapy. We report the case of a woman who suffered intrahepatic hemorrhage presenting with acute abdominal pain and vomiting after the use of enoxaparin for total hip arthroplasty.- - - - - - - - - - ranking = 0.83333333333333keywords = hip (Clic here for more details about this article) |
3/101. A new case of NSAID-induced infertility.A 38-year-old woman on piroxicam for hip osteoarthritis secondary to hip dysplasia developed secondary sterility. Ova collected for in vitro fertilization were immature and failed to fertilize. A further attempt done after piroxicam discontinuation produced seven mature ova that fertilized, allowing embryo implantation. Nonsteroidal antiinflammatory drugs may induce infertility by reducing the production of prostaglandins, most notably via inhibition of the enzyme cyclooxygenase 2. The impact of nonsteroidal antiinflammatory drug therapy on reproductive function needs to be evaluated.- - - - - - - - - - ranking = 0.33333333333333keywords = hip (Clic here for more details about this article) |
4/101. Total hip arthroplasty after failed intertrochanteric valgus osteotomy for advanced osteoarthrosis.Thirty hips that had undergone conversion total hip arthroplasty because of failed intertrochanteric valgus osteotomy for advanced osteoarthrosis were analyzed clinically and radiographically for more than 2 years. The average followup after total hip arthroplasty was 7 years (range, 2-18 years). The average age of the patients at the time of valgus osteotomy was 42 years (range, 30-63 years). The average age of the patients at the time of conversion total hip arthroplasty was 57 years (range, 43-76 years), and the average period between valgus osteotomy and conversion was 14 years (range, 3-24 years). Perioperative complications in conversion total hip arthroplasties were minimal, and intramedullary reaming was performed easily. Of the 30 conversion total hip arthroplasties, 12 cemented and 18 cementless components were used, respectively. Kaplan-Meier's survival analysis indicated that survivorship of cemented stems was significantly higher than that of conventional cementless stems. Cemented stems are preferable for conversion total hip arthroplasty after failed femoral valgus osteotomy.- - - - - - - - - - ranking = 2keywords = hip (Clic here for more details about this article) |
5/101. Penetrating bladder injury caused by a medially placed acetabular screw.Cancellous bone screws are frequently used to improve the early stability of HA coated acetabular components during total hip arthroplasty. Avoidance of the anterosuperior and anteroinferior quadrants is recommended for transacetabular screw placement to minimize the risk of injury to intrapelvic structures. Revision arthroplasty in rheumatoid patients presents additional hazards in that the acetabular bone is often soft and deficient, and the protective depth of obturator internus and psoas is usually reduced. I report a case of delayed, but fatal, perforation of the bladder associated with a medially placed acetabular screw during revision arthroplasty in a rheumatoid patient. Unless directed safely into the superior pubic ramus, anterior quadrant screws should be avoided in these circumstances.- - - - - - - - - - ranking = 0.16668421887929keywords = hip, injury (Clic here for more details about this article) |
6/101. liposarcoma in association with total hip replacement.A possible relation between joint replacement and malignancy has previously been suggested in a few cases. In the majority of these cases, the authors found either malignant fibrous histiocytomas or osteosarcomas. We hereby report the first case of a liposarcoma in the vicinity of a joint prosthesis.- - - - - - - - - - ranking = 0.66666666666667keywords = hip (Clic here for more details about this article) |
7/101. indomethacin-induced postoperative psychosis.indomethacin is used commonly for the prevention of postoperatively heterotopic ossification. There have been 3 reports in the pharmacologic literature of indomethacin-induced psychosis. We describe a case of indomethacin-induced psychosis in a patient in whom indomethacin was used for the prevention of postoperative heterotopic ossification after bilateral uncemented total hip replacements.- - - - - - - - - - ranking = 0.16666666666667keywords = hip (Clic here for more details about this article) |
8/101. Femoral bone regeneration subsequent to impaction grafting during hip revision: histologic analysis of a human biopsy specimen.Cemented revision with impaction grafting shows encouraging early clinical results; postoperative biopsy specimens taken from the proximal femur in humans have demonstrated viable trabecular and cortical bone. Human radiographic studies also illustrate density changes within the proximal femur, consistent with remodeling of bone-graft. In an animal experiment, bone incorporation was shown in the proximal femur, but graft lysis was reported around the distal portion of the implant. We report on a patient who sustained a traumatic femoral fracture at the level of the tip of the femoral component 27 months after revision with impaction grafting and a collarless polished taper stem. At the time of open reduction and internal fixation of the fracture, we obtained circumferential biopsy specimens from the fracture site. Three distinct zones could be identified histologically: i) an inner zone consisting of bone-cement, fibrous tissue, and partially necrotic trabeculae with evidence of bone remodeling; ii) a middle zone consisting of viable trabecular bone and probable neocortex formation with fewer particles of bone-cement; and iii) an outer zone with viable cortex. Fibrous tissue was present around some of the incorporating bone-graft fragments, but no continuous fibrous membrane was present. Cement particles were identified, but no polyethylene debris was found by light microscopy. biopsy specimens from the distal aspect of the prosthesis may not reflect changes seen proximally, but based on the available tissue, this case illustrated histological evidence of bone-graft remodeling after impaction grafting. These results are consistent with our expectations based on radiographic findings and clinical results.- - - - - - - - - - ranking = 0.66666666666667keywords = hip (Clic here for more details about this article) |
9/101. Pathophysiology of surgical site infection in total hip arthroplasty.This article is a case report of a 69-year-old man who underwent a right total hip replacement procedure and developed a surgical site infection. Areas of concern in prevention and treatment of hip arthroplasty infection are presented, focusing on the pathophysiologic process involved. A review of the patient risk factors and the pathophysiologic action potentiating risk for infection include host immunity, nutritional status, diabetes, age, use of steroids or immunosuppressive drugs, rheumatoid arthritis, and urinary tract or other infections. The case report identifies the patient's age, multiple instrumentation of the bladder resulting in bacteriuria and the reinfusion of 400 cc of autologous shed blood via cell saver, a controversial risk subject, as the primary risk factors for surgical site infection in this patient. Readmission to the hospital on day 16 after the operation was completed on identification of 2 pathogenic organisms, methicillin-resistant staphylococcus aureus and acinetobacter calcoaceticus bio anitratus. The infection was successfully treated with oral ciprofloxacin and intravenous administration of tobramycin, preventing progression from superficial to deep infection and preserving the prosthesis.- - - - - - - - - - ranking = 1keywords = hip (Clic here for more details about this article) |
10/101. Bilateral hip arthroplasty for ochronotic arthropathy.ochronosis is a musculoskeletal manifestation of alkaptonuria, a rare hereditary metabolic disorder characterised by the absence of the enzyme homogentisic acid oxidase and associated with various systemic abnormalities related to the deposition of homogentisic acid pigment (ochronotic pigment). In this report, we describe a 53-year-old, HLA-B27( ) woman with ochronotic arthropathy. In addition to the typical clinical features of the disorder, she had bilateral hip involvement, which was improved by cementless total hip prosthesis.- - - - - - - - - - ranking = 1keywords = hip (Clic here for more details about this article) |
