PURPOSES: Osteonecrosis of the femoral head (ONFH) is a dramatic condition resulting in joint destruction in the late stages. Total hip arthroplasty allows function recovery with satisfactory implant survival. Recently, the use of uncemented short stems has been suggested to improve the conservation of bone stock. METHODS: We performed a retrospective study on 16 hip arthroplasties-11 patients-implanted for ONFH between 2008 and 2017. We aimed to compare the outcomes of the two types of arthroplasty-"uncemented short" vs "cemented conventional" femoral stem-in terms of pain (visual analogue scale), function (Harris Hip Score), and survival (radiography)...

Background: Nerve palsy following total hip arthroplasty (THA) is a complication that worsens the functional prognosis. The present study analyzed the risk factors of nerve palsy following THA. Methods: The subjects of this study included 6,123 cases in which primary THA was performed under spinal anesthesia with cementless implants used in the posterolateral approach. Results: Fourteen cases (0.22%) developed nerve palsy following THA, all of which involved palsy of the entire peroneal nerve region...

PURPOSE: To identify modifiable factors related to post-operative dislocation and reoperation in patients with osteonecrosis of the femoral head (ONFH) in a large cohort. METHODS: We studied 4995 hip arthroplasties: total hip arthroplasty (THA) was performed in 79% of patients; bipolar hemiarthroplasty (BP), 17%; total resurfacing arthroplasty (tRS), 3%; and hemi-resurfacing arthroplasty (hRS), 1%. A new type of BP (accounting for 49% of BPs) comprised a femoral component with a polished or smooth, small-diameter (approximately 10 mm) neck with a round or oval axial cut surface and no sharp corners...

INTRODUCTION: High-energy femoral neck fractures in young patients can be devastating, with the risk of osteonecrosis, nonunion, malunion and lifelong morbidity. The aim of this study is to define the effects of patient, fracture and surgical factors on the outcome of high-energy femoral neck fractures in patients aged from 15 to 50 years. METHODS: A retrospective review was conducted of high-energy femoral neck fractures in patients aged 15-50 managed surgically at a Level 1 Trauma Centre, using a prospectively recorded trauma database...

PURPOSE: Core decompression (CD) may be effective when performed during the early stages of osteonecrosis of the femoral head (ONFH). Tantalum may be added as a rod that would allow putting some mechanical constraints on the femoral head. We aimed to estimate the rate of total hip arthroplasty after CD and insertion of a tantalum rod during early stages of OFNH. METHODS: We searched systematically Medline via PubMed and the Cochrane Library. Our primary endpoint was the rate of patients undergoing a total hip arthroplasty after CD and insertion of a tantalum rod...

PURPOSE: We had previously established concentrated autologous bone marrow aspirate transplantation (CABMAT), a one-step, low-invasive, joint-preserving surgical technique for treating osteonecrosis of the femoral head (ONFH). This study aimed to evaluate the effects of CABMAT as a hip-preserving surgical approach, preventing conversion to total hip arthroplasty (THA) and femoral head collapse in patients with systemic lupus erythematosus (SLE). METHODS: Since 2003, 52 SLE patients (8 male, 44 female, 92 hips, mean age 35...

PURPOSE: Osteonecrosis of the femoral head (ONFH) is commonly detected in young patients and most surgeons tend to delay total hip arthroplasty (THA) until the end stage of the disease. We hypothesised that post-operative range of motion (ROM) of the hip as well as baseline ROM at the time of surgery decreases with the disease progression. The purpose of this study was to determine whether patients, who were operated at an advanced stage, have pre- and post-operative hip ROM similar to ROM of patients, who were operated at earlier stages...

Subchondral insufficiency fracture (SIF) is a fragility fracture secondary to osteoporosis that leads to collapse of the femoral head with no evidence of osteonecrosis. SIF of the femoral head has been reported in adults of varying ages and both sexes, but it has never been reported to occur in pregnant women. Herein, we describe a 40-year-old primiparous patient with pre-existing anorexia nervosa who developed SIF of the femoral head in the third trimester. At 29 weeks of gestation, the patient complained of sudden pain on walking in both hips...

PURPOSE: This study aimed to determine the correlation between the change in joint line height calculated from the resected bone and insert thickness during surgery and the change in limb alignment following unicompartmental knee arthroplasty (UKA). It was hypothesized that joint line elevation is correlated with the change in limb alignment. METHODS: A total of 74 consecutive patients diagnosed with either isolated medial compartmental osteoarthritis (38 patients) or spontaneous osteonecrosis of the knee (36 patients) were included...

Collapse of the femoral head is the most significant pathogenic complication arising from osteonecrosis of the femoral head. It is related to the disruption of the maintenance of cartilage and bone, and results in an impaired function of the vascular component. A method for predicting the collapse of the femoral head can be treated as a type of clinical index. Efforts in recent years to predict the collapse of the femoral head due to osteonecrosis include multiple methods of radiographic analysis, stress distribution analysis, finite element analysis, and other innovative methods...

Osteonecrosis of the femoral head (ONFH) is a devastating condition affecting relatively young patients whereby the femoral head is necrotic, resulting in significant pain, articular surface collapse, and eventual osteoarthritis. This condition has been highly associated with chronic steroid use, alcoholism, and hip trauma, as well as other less common conditions. Without intervention, this condition has a high likelihood of progressing and developing into end-stage osteoarthritis. Unfortunately, ONFH is difficult to diagnose on plain radiographs in the early stages of the disease, and often requires more advanced imaging modalities such as MRI in order to fully assess for early degeneration...

PURPOSE: The purposes of this study were to document novel Raman spectroscopic findings in femoral heads affected by osteonecrosis and to identify molecular structure differences based on aetiology. METHODS: We obtained 13 femoral heads with osteonecrosis from 13 different patients who underwent total hip arthroplasty. Comparisons were made between the viable zones of each femoral head examined. The samples were scanned with X-ray micro-CT for structural mapping and a central coronal section slab was prepared for Raman spectroscopy and histological analyses...

PURPOSE: Short-stem hip arthroplasty has the potential advantage of femoral bone stock preservation, especially in view of the expected revisions in the often relatively young patients. Despite short-stem hip prosthesis are increasingly used for total hip arthroplasty, there are no sufficient mid- and long-term results especially for patients with avascular femoral head osteonecrosis. The present study investigates mid-term functional results as well as the revision rate following implantation of a short-stem prosthesis...

PURPOSE: As the medical treatment of systemic lupus erythematosus (SLE) has evolved, the rate of total hip arthroplasty (THA) in SLE patients has increased, with osteonecrosis (ON) being the primary indication for arthroplasty in a quarter of cases. Comparative literature evaluating outcomes following THA for patients with SLE and ON versus patients with non-SLE-related ON or patients with osteoarthritis (OA) is limited. The goal of the present study was to investigate the current trend in SLE patients undergoing THA and compare complications following THA for ON with SLE, ON without SLE, and OA...

BACKGROUND: Many studies have confirmed that the size and location of necrotic lesions are major factors that affect the prevalence of collapse and prognosis in patients with osteonecrosis of the femoral head (ONFH). Although several classification systems categorize and quantify ONFH, there is no agreement on which one is most useful for the purpose. QUESTIONS/PURPOSES: We compared the Steinberg, modified Kerboul, and Japanese Investigation Committee (JIC) classifications of ONFH in terms of (1) the correlation among the three different classification systems...

PURPOSE: For successful joint preservation in osteonecrosis of the femoral head (ONFH), it is important to understand the mechanism of collapse. The purpose of this study was to investigate the initiation of subchondral fracture in ONFH by using micro-CT imaging of the whole femoral head, focusing on the three-dimensional relationship between the subchondral fracture and the bone resorption area. METHODS: A total of 40 femoral heads from 37 patients retrieved during total hip arthroplasty for stage 3A or 3B ONFH by Japanese Investigation Committee criteria were scanned using micro-CT with a 0...

Introduction: Head and neck resection of the femur was described by Girdlestone in 1928 in the treatment of coxalgia. Very invasive at the beginning, this intervention is much less so today, but the term of "Girdlestone's operation" or "Girdlestone's procedure" has remained in use. The reported results are controversial. In resource-limited countries, Girdlestone's procedure is often indicated for lack of a better one. In this context, we report the results of a series of 24 patients operated in a regional hospital (Ouahigouya, Burkina Faso) with the aim of showing that this technique remains valid and can be benefit...

BACKGROUND: Randomized trials have shown the benefits of injecting bone marrow-derived mesenchymal stem cells (BmMSCs) after standard hip decompression in patients with osteonecrosis of the femoral head. However, the combination of BmMSCs and platelet-rich plasma (PRP) injected into the femoral head after decompression has not been reported previously. This study reports the results in a preliminary series of patients with osteonecrosis of the femoral head treated with BmMSCs plus PRP...

BACKGROUND: Hip replacements are successful in restoring mobility, reducing pain, and improving quality of life. However, the association between THA and the potential for increased life expectancy (as expressed by mortality rate) is less clear, and any such association could well be influenced by diagnosis and patient-related, socioeconomic, and surgical factors, which have not been well studied. QUESTIONS/PURPOSES: (1) After controlling for birth year and sex, are Swedish patients who underwent THA likely to survive longer than individuals in the general population? (2) After controlling for relevant patient-related, socioeconomic/demographic factors and surgical factors, does relative survival differ across the various diagnoses for which THAs were performed in Sweden? METHODS: Data from the Swedish Hip Arthroplasty Register, linked to administrative health databases, were used for this study...

We explored the mechanism of early stage osteonecrotic femoral head collapse by analyzing and comparing different regions in human osteonecrotic femoral head samples. Eight osteonecrotic femoral heads (ARCO II-III) were obtained from patients undergoing total hip arthroplasty. Bone structure was observed and evaluated by micro-computed tomography (CT) scans and pathology. Osteoblast and osteoclast activities were detected by tartrate-resistant acid phosphatase, alkaline phosphatase, and immunofluorescent staining...
