Efficacy of an Abduction Brace in Preventing Initial Dislocation in the Early Postoperative Period after Primary Total Hip Arthroplasty  [PDF]
Yoshinori Ishii, Hideo Noguchi, Mitsuhiro Takeda, Junko Sato, Yoichiro Domae
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.33026
Abstract: We hypothesized that a hip brace may prevent the initial dislocation in the early postoperative period after total hip arthroplasty (THA). We performed a prospective evaluation of the efficacy of a brace in preventing dislocation in 54 primary THAs in 43 patients. All of the patients wore braces for 3 weeks postoperatively. The occurrence of dislocation was evaluated six months postoperatively. There were no cases of dislocation while wearing a brace, while two posterior dislocations occurred 8 and 12 days postoperatively while picking something up from the floor without a brace in so-called provocative positions. The results of this study suggest that a hip brace helps patients to recognize careless provocative positions and prevents the initial hip dislocation in this period instead of usual postoperative management for an average of 6 weeks after discharge, such as a high toilet seat, restricted hip flexion in the activities of daily living, use of a reacher or grabber, an abduction pillow, and a high chair.
Long Term Effects of Radiation-Induced Osteonecrosis of the Pelvis Caused Complete Failure of Total Hip Arthroplasty  [PDF]
Tigist Wodaje, Per Wretenberg
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.37074
Abstract: This case report describe severe osteonecrosis of the pelvis more than 30 years after radiation due to ovarian cancer. As orthopedic surgeon it is important to ask about previous radiation to the pelvis in case of total hip arthroplasty and also to perform CT in unclear cases.
Surgical Outcome Following Hip Fracture in Patients > 100 Years Old: Will They Ever Walk Again?  [PDF]
Sachin Patil, Bertrand Parcells, Alexis Balsted, Ronald S. Chamberlain
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.311109
Abstract: Introduction: Advances in medicine have led to a growth in the centenarian population (>100 years old). Centenarians are a largely unstudied population but as longevity increases, so will the cost of providing care for this group. Methods: One hundred and ten patients were admitted to SBMC 195 times between 2000 and 2009. Thirteen patients were treated for hip fracture. Data abstracted from the charts of these patients including age, gender, ethnicity, co-morbidities, advance directives (ADRs), functional status, length of stay (LOS), pre-operative and post-operative residential status and ambulatory status, ASA grade, type of anesthesia, duration of surgery and for complications of surgery or anesthesia. Results: The mean age was 101.2 years (100 to 104 years) with an M:F ratio of 2:11. The most common co-morbidities were hypertension, anemia, congestive heart failure (CHF) and coronary artery disease. Among the 13 patients with hip fractures, 12 had operative intervention while one was treated conservatively. The mean ASA grade was 2.75 (1 - 4). Five patients had surgery under general anesthesia and seven received spinal anesthesia. Five patients received a bi-polar hip replacement and seven patients underwent internal fixation. The mean operative time was 47.6 min (27 - 90 min). Five (41.7%) patients required a peri-operative blood transfusion. The mean post-anesthesia recovery score was 9.42 (9 - 10). All patients, except two, were returned to their pre-operative ambulatory status. Advanced directives were held by only 30.8% of patients on admission. There were 2 post-operative morbidities and 1 mortality. Conclusions: Centenarians represent a high-risk-surgical population due to their age and associated comorbidities. Hip fracture is the cause of >10% of all admissions and accounts for 29% of all surgical procedures in this age group. Despite their age and comorbidities, surgery for hip fracture is well tolerated and nearly all patients were returned to their pre-hospital ambulatory status. Education on advanced directives is lacking.
Acute Hip Pain—A Forgotten Cause  [PDF]
Tzay-Ping Fua, Yee Han Dave Lee
International Journal of Clinical Medicine (IJCM) , 2016, DOI: 10.4236/ijcm.2016.73018
Abstract: This is a case of acute left hip pain in a young male patient presenting to the Emergency Department (ED). The hip joint is painful with limited range of motion, and the patient is admitted to rule out septic arthritis of the hip. The subsequent inpatient serum uric acid level performed is elevated and the Magnetic Resonance Imaging (MRI) hip reveals a moderate hip effusion. A Computer Tomography (CT) guided hip joint aspiration confirms the diagnosis of gout with uric acid crystals seen in the hip synovial fluid analysis. The patient is treated as for gout with marked improvement in his symptoms.

Macedo, Carlos Alberto de Souza;Scheidt, Rodrigo Benedet;Palma, Humberto Moreira;Rosito, Ricardo;Weissheimer Junior, Walmor;Galia, Carlos Roberto;
Acta Ortopédica Brasileira , 2008, DOI: 10.1590/S1413-78522008000400006
Abstract: the objective of the study was to assess clinical-x-ray endpoint on a cohort of 48 patients (54 hips) submitted to spotorno? primary non-cemented total hip arthroplasty in the last 20 years (1985 - 2005), with mean follow-up time of 17.5 years (range: 8-20 years). in the clinical and functional evaluation, 92.7% good outcomes were achieved. osteopenia was found in 24 acetabula (44.4%) and 30 femurs (55.6%); a mean of 2 millimeters (0-5 mm) of polyethylene wear-off was present in 43 acetabula (79.6%). the statistical analysis of the results suggested that the presence of osteopenia is not associated to the clinical endpoint (p=0.75); polyethylene wear-off as well as the presence of osteopenia was more significant if patients below the age of 55 years (p<0.05). we concluded that the use of a spotorno? prosthesis on this cohort showed god outcomes, similar to those previously reported in literature.

Revista Brasileira de Ortopedia , 2009, DOI: 10.1590/S0102-36162009000600008
Abstract: objectives: our primary aim was to evaluate the occurrence of dislocation of non-cemented total hip arthroplasty, when using the posterior and the direct lateral approaches. methods: we performed a comparative retrospective study with 232 patients submitted to non-cemented total hip arthroplasty, due to the diagnosis of primary or secondary osteoarthritis. the posterior approach was used in 105 patients while direct lateral approach was used in 127 patients. there was only one prosthesis model and the same rehabilitation program and post-operative care was used for all patients. we checked the occurrence of dislocation, the acetabular positioning and also the size of the components. results: there was only one case of dislocation, treated with closed reduction successfully. this was a 47 year-old female, submitted to direct lateral approach. the mean follow-up time for both groups was 23.7 months, ranging from six to 42 months. conclusion: the authors conclude that the prevalence of total hip arthroplasty dislocation is similar for both approaches, and educational measures besides the use of a higher femoral offset seem to reduce the risk of this complication.
Evaluación clínica de resultados de prótesis total de cadera
Revista Cubana de Ortopedia y Traumatolog?-a , 1998,
Abstract: the clinical evaluation of the results of 33 hips operated on with total primary hip prothesis in 28 patients aged 28-81, who had been surgically treated more than 2 years age due to different causes, which had led to previous operations by other techniques, is presented. the scoring system used by the "hermanos mayo" clinic, in 1985, that grants a maximum of 80 points for clinical results was selected for the evaluation. the mean scoring was 67.9. 16 hips obtained a higher scoring (48.5 %). in the final result, 28 hips were between excellent and good (80-60 points), accounting for 84 %, which represents an adequate reincorporation of our patients to social life.
A late dissociation of the ceramic component of a sandwich liner cup in a total hip arthroplasty
—Case report and review of the literature

Pieter-Jan De Roo, Franky Steenbrugge, Martijn Raaijmaakers
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.22037

We present a case of a 71-year-old woman with unexplained instability of her total hip arthroplasty 12 years after implantation due to loosening of the ceramic component of a sandwich ceramic in polyethylene liner. She experienced in total 2 dislocations in 6 months. These events occurred without fracture of the ceramic liner. Sandwich ceramic liners were introduced with the idea of combining the benefits of ceramic and polyethylene bearings in total hip arthroplasty in order to reduce wear and to allow a ceramic on ceramic bearing to be used in a cup designed for polyethylene inserts only. Although some reports showed promising early results, case reports and later on retrospective analysis showed high fracture rates of the ceramic liner component. We believe that loosening of the ceramic component may precede fracture of the liner and that a ceramic on ceramic configuration is preferable.

Hip Arthroscopy in Children under the Age of Ten  [PDF]
Oliver Eberhardt, Thomas Wirth, Francisco Fernandez Fernandez
Open Journal of Orthopedics (OJO) , 2013, DOI: 10.4236/ojo.2013.31009
Abstract: Arthroscopic hip surgery has become an established diagnostic and therapeutic method for addressing different hip pathologies. This paper focuses on hip arthroscopy for treating hip disorders in children under the age of 10. Arthroscopic hip surgery was performed 30 times on 24 children to address various hip pathologies. Indications were septic arthritis, benign soft tissue tumors, traumatic and congenital hip dislocation, juvenile idiopathic arthritis and osteochondroma of the acetabulum. Diagnostic arthroscopy was technically feasible in all cases. All cases of septic arthritis were successful treated using arthroscopic lavage and antibiotics. In the miscellaneous cases (benign fibrous tumor, juvenile idiopathic arthritis, osteochondroma congenital hip dislocations and traumatic hip dislocation) 4 hips had additional open surgery including surgical dislocation with synovectomy, open reduction and stabilization of the fractured posterior rim of the acetabulum, acetabulopasty and open resection of an osteochondroma with acetabuloplasty. In conclusion arthroscopic hip surgery is an additional diagnostic and therapeutic method that is suitable for treating different hip pathologies in children under the age of 10. Primary treatment of septic arthritis can be done easy by hip arthroscopy. Using cannulated mini arthroscopic hip instruments (2.7 mm), the range of application can be expanded to include treatment of very young infants. Hip arthroscopy can reduce the need of open surgery but cannot replace bony procedures in hip surgery.
Effects of Hip Arthroplasties on Bone Adaptation in Lower Limbs: A Computational Study  [PDF]
Abdul Halim Abdullah, Mitsugu Mitsugu Todo
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.34001

Gait disorders contribute to the risk of falls and successive injuries, especially to elderly populations. The risk of falls becomes higher for hip osteoarthritis (OA) and hip arthroplasties patients due to poor balancing and gait impairment. Bone adaptation and bone loss are fundamental issues in considering the changes of bone behavior and gait pattern. In this study, computational analysis of the lower limbs was conducted to estimate the bone adaptation after hip arthroplasties procedure. 3D inhomogeneous model of lower limb was developed from computed topography (CT- based) data of 79 years old patient with hip osteoarthritis problem in left limb. Two types of arthroplaties were constructed in the left limb, namely total hip arthroplasty and resurfacing hip arthroplasty using commercial biomedical software, Mechanical Finder v6.1. Prosthesis stem and acetabular cup of THA were modelled as titanium alloy material (E = 114 GPa, v = 0.34), femoral ball and bearing insert as alumina properties (E = 370 GPa, v = 0.22). Meanwhile, RHA implant was assigned as Co-Cr-Mo material (E = 230 GPa, v = 0.30). Contact between both implants and bone were considered to be perfectly bonded at the interface. A load case of quiet standing position was conducted in this analysis with 60 kg of the patients’ body weight. The load was applied at the cross sectional lumbar vertebra and fixed at the distal of femoral shafts. Results show different patterns of stress distribution in right and left (operated) limbs for hip OA, THA and RHA models. An indication of stress alteration on both limbs after arthroplasties suggested that the bone adaptation occurred. The higher percentage of change in the left limb projected that the adaptation was more critical in operated limb.
