Abstract
BACKGROUND Several hip preserving techniques have been described for the management of osteonecrosis of the femoral head (ONFH). This systematic review identified prognostic factors in the treatment of ONFH that are associated with treatment failure and conversion to total hip arthroplasty (THA). MATERIAL AND METHODS This study followed the PRISMA guidelines. The literature search was conducted in November 2021. All clinical trials comparing two or more treatments for femoral head osteonecrosis were accessed. A multivariate analysis was performed to investigate the association between baseline characteristics and the surgical outcome. A multiple linear model regression analysis through the Pearson Product-Moment Correlation Coefficient (r) was used. RESULTS Data from 88 articles (6112 procedures) were retrieved. Female gender was associated with increased time to THA (P = 0.03) and reduced rate of THA (P = 0.03). Longer symptom duration before treatment was associated with shorter time to failure (P = 0.03). Increased pre-treatment VAS was associated with reduced time to failure (P = 0.03) and time to THA (P = 0.04). Reduced pre-treatment hip function was associated with increased rate of THA (P = 0.02) and failure (P = 0.005). Patient age and BMI, aetiology, time from surgery to full weight bearing and the side did not show evidence of a statistically significant association with the surgical outcome. CONCLUSION Male gender, longer symptom duration before treatment, higher VAS scores, and lower HHS scores were negative prognostic factors after treatment for osteonecrosis of the femoral head.

Abstract
Osteonecrosis is a degenerative bone disease brought on by a change in subchondral blood flow and characterized by the loss of bone cellular components. Other names for it include ischemic bone necrosis, aseptic necrosis, and avascular necrosis. Long bones' epiphyses in weight-bearing joints are typically impacted. In extreme cases, a joint may completely collapse or subchondral bone may be obliterated. Avascular necrosis, which most frequently affects joints, especially the femoral head, occurs when the blood supply to the bones is diminished. In this article, we will explain the clinical case of a 40-year-old man who's been complaining about hip pain for two months. The patient went to Acharya Vinobha Bhave Rural Hospital (AVBRH) with the same complaint and underwent some tests; upon inspection, it was discovered that the patient had bilateral avascular femoral head necrosis. For avascular necrosis (AVN) of the left femoral head, the patient had core decompression surgery. Once post-operative physical therapy was initiated, the condition significantly improved, and it also served to prevent additional abnormalities. The goal of this case study is to examine the therapeutic strategies essential for treating bilateral femoral head avascular necrosis.

Study on the outcome of patients with aseptic femoral head necrosis treated with percutaneous multiple small-diameter drilling core decompression: a retrospective cohort study based on magnetic resonance imaging and equivalent sphere model analysis. J Orthop Surg Res 2020; 15:264. [PMID: 32669119 PMCID: PMC7362550 DOI: 10.1186/s13018-020-01786-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Accepted: 07/06/2020] [Indexed: 11/24/2022] Open
Abstract
Background Aseptic necrosis of the femoral head (ANFH) has a high incidence in the community and causes substantial problems with health as well as economic and social stress. Core decompression is the most commonly used treatment for early ANFH. Although many studies have reported on the efficacy of femoral head core decompression surgery for ANFH, there are still some shortcomings in assessing the severity of femoral head necrosis, the location distribution, and changes in necrotic lesions before and after surgery. Magnetic resonance imaging (MRI) and equivalent sphere model analysis were used to further clarify the clinical efficacy of percutaneous multiple small-diameter drilling core decompression in patients with ANFH. Methods From July 2013 to November 2016, 24 patients (32 cases of the hip joint) with ANFH who underwent percutaneous multiple small-diameter drilling core decompression were selected, and a retrospective analysis was conducted. MRI as well as VAS, OHS-C, and HHS scores were used to evaluate joint function in all patients before and 6, 12, and 24 months after the operation. Results Twenty-four months after the operation, 10 hips were amputated. The survival rates of alcoholic femoral head necrosis (AFNH), idiopathic femoral head necrosis (IFHN), and steroid-induced femoral head necrosis (SIFHN) patients at 24 months were 100%, 85.7% (− 2 hips), and 0.0% (− 8 hips), respectively. The MRI and equivalent sphere analysis results revealed that the anterior superior medial quadrant was the area most prone to osteonecrosis, and the posterior superior medial quadrant was the area second most prone to necrosis. After the operation, the average percentage of the AFHN necrosis area in the total volume of the femoral head decreased from 14.5 to 10.3%, and the average percentage of the IFHN necrosis area decreased from 16.3 to 9.2%; however, the average percentage of the necrosis area for SIFHN increased from 30.4 to 33.1%. Conclusion Percutaneous multiple small-diameter drilling core decompression significantly reduced the lesion volume for AFHN and IFHN, but the effect on SIFHN was not good.

Abstract
BACKGROUND The purpose of this study was to compare the clinical and radiological outcomes of multiple small diameter drilling and core decompression with fibular strut grafting in the management of non-traumatic avascular necrosis (AVN) of the femoral head. MATERIALS AND METHODS Outcomes of patients with AVN treated by multiple small diameter drilling (group 1) were compared retrospectively with patients treated by core decompression and fibular grafting (group 2). Harris hip score (HHS) was used to assess the clinical status pre- and postoperatively. Modified Ficat and Arlet classification was used to assess the radiological stage pre- and postoperatively. RESULTS Forty-six patients (68 hips) were included in this study. Group 1 consisted of 33 hips, and group 2 consisted of 35 hips. In stages I and IIB, there was no statistically significant difference in the final HHS between the two groups. However, in stages IIA and III, hips in group 2 had a better final HHS (P < 0.05). In terms of radiographic progression, there was no statistical difference between hips in stages I, IIA and stage IIB. However, in stage III, hips belonging to group 2 had better results (P < 0.05). Kaplan-Meier survivorship analysis showed better outcome in group 2 in stage III (P < 0.05). CONCLUSIONS Hips with AVN in the precollapse stage can be salvaged by core decompression with or without fibular grafting. Multiple small diameter drilling is relatively simple and carries less morbidity and hence preferred in stages I and II. However, in stage III disease, core decompression with fibular strut grafting gives better results.

Abstract
The review describes the following: (1) how traditional core decompression is performed, (2) adjunctive treatments, (3) multiple percutaneous drilling technique, and (4) the overall outcomes of these procedures. Core decompression has optimal outcomes when used in the earliest, precollapse disease stages. More recent studies have reported excellent outcomes with percutaneous drilling. Furthermore, adjunct treatment methods combining core decompression with growth factors, bone morphogenic proteins, stem cells, and bone grafting have demonstrated positive results; however, larger randomized trial is needed to evaluate their overall efficacy.

Abstract
Background: Avascular necrosis (AVN) of femoral head is one of the multifactorial pathologies, which can disturb hip joint and its range of motion. There have been several therapeutic methods for this pathology, but the results are controversial. Some studies show that core compression prevents the progress of the disease and its symptoms. This study aims to explore this issue. Materials and Methods: This clinical trial was conducted on patients who were diagnosed with AVN of femoral head stage I, IIA, at educational hospitals of Isfahan in 2010. The patients who met the inclusion criteria and suffered from AVN of femoral head stage I, IIA for any reason (primary or secondary), entered the study. Six and 12 months after surgery, final assessment in terms of range of motion, return to work, and severity of pain based on vancouver associated score (VAS) was made and recorded. The duration of hospitalization and rate of infection were also recorded. The data were entered into and analyzed by the SPSS software. Results: Mean and standard deviation of pain severity before surgery was 6.82 ± 1.74 in the participants. After 6 months, pain severity reduced to 4.05 ± 1.29, and after 12 months, it reached 2.41 ± 1.82. On the basis of analysis of variance with repeated observation, the severity of pain was significantly reduced in 1 year (P<0.001). Conclusion: It can be concluded that core decompression in patients with AVN of femoral head stage I, IIA can improve pain in hip area and increase range of motion.

Abstract
The aim of this report is to present our experience on the use of the digital subtraction angiography (DSA) in selection of the vascularized greater trochanter bone grafting for the treatment of the osteonecrosis of femoral head (ONFH) in early stages. Between January 2005 and June 2007, DSA was used to evaluate the blood perfusion of the early stages ONFH in 32 patients (45 hips). There were 18 males and 14 females with an average age of 30 years old. Twenty-one hips were in ARCO stage I, and 24 in ARCO stage II. The arterial blood supply insufficiency was found in 22 hips by DSA, and the venous stasis in 23 hips. The hips with artery blood supply insufficiency received the vascularized greater trochanter bone grafting, and the hips with the venous stasis received the core decompression. All of patients were followed-up with an average of 4.8 years (ranging 2.4-6.6 years). The preoperative Harris Hip score (HHS) in the patients with arterial blood supply insufficiency was 48.18 ± 7.81 and the postoperative HHS was 93.27 ± 3.03. The preoperative HHS in the patients with venous stasis was 44.04 ± 6.40, and the postoperative HHS 92.65 ± .93. The postoperative DSA showed an improved perfusion of the femoral head in 44 hips. Our experience showed that DSA would help to select the appropriate procedure for treatment of ONFH in the early stage.

Abstract
INTRODUCTION Single surgeon studies from specialized centers have suggested that metal-on-metal hip resurfacing in patients with osteonecrosis of hip joint provides good implant survival and function. METHOD We tested the hypothesis that multicenter results of hip resurfacing, in terms of function and survival, are similar between patients with osteoarthritis and osteonecrosis. PATIENTS 192 patients (202 hips) underwent metal-on-metal hip resurfacing at different centers around the world. We compared the revision risks in 95 patients (101 hips) with osteonecrosis and 97 patients (101 hips) with osteoarthritis. RESULTS The mean age at operation was 42 and 43 years and the preoperative and postoperative Harris hip scores were 62 and 96 and 58 and 95 for osteonecrosis and osteoarthritis groups. Survival with revision for any reason as the end point at last follow-up was 97.7% for osteonecrosis and 95.0% for osteoarthritis. CONCLUSION We conclude that hip resurfacing can be offered to patients with osteonecrosis.

Abstract
INTRODUCTION The young age of patients, total arthroplasties complications risks, and implant costs justify evaluation of the results of core decompression in the treatment of sickle-cell disease avascular necrosis of the femoral head (ONFH). HYPOTHESIS In sickle-cell disease necrosis, core decompression offers good relief from pain and delays the use of total arthroplasty in comparison to a conservatively treated control group by a simple non-weight bearing protocol. MATERIALS AND METHODS From 1994 to 2008, among 215 drepanocytic adults, 42 patients (22 genotype SS, 20 genotype SC; 15 men, 27 women) presented symptomatic ONFH. We report the data from a prospective study of two patients' groups: a non-operated group (16 patients aged 36.5+/-6.5 years, 23 hips) and an operated group (26 patients aged 30.3+/-2.8 years, 42 hips). The results were considered on the basis of change in clinical status according to the numeric evaluation of pain scale, the functional score of Merle d'Aubigné-Postel (MAP), the radiological progression of lesions, and the time delay to total arthroplasty. RESULTS Twenty-three hips were conservatively treated by discharge (a pair of canes). After a follow-up period of 13.4+/-0.5 years, no pain improvement was noted (p=0.76), and MAP score was unchanged (p=0.27). Out of 23 hips managed by discharge, 9 stage IV hips (degenerative arthritis, 39.1%) underwent arthroplasty after an average delay of 2.6+/-2.4 years. Forty-two hips were treated by core decompression. The duration of follow-up was 11.3+/-1.8 years. Postoperatively, pain reduction and MAP score improvement were significant in 39 out of 42 hips (93%, p<0.0001). Twenty-nine out of these 42 hips had a favorable evolution. Ten hips (23.8%) progressed to total arthroplasty, after a period of 7.4+/-2.7 years, longer than the one of the non-operated group (p=0.0007). By comparing the two groups (operated and non-operated), the benefit of core decompression appeared very significant (p<0.0001). In addition to allocating patients osteonecrosis stages, the Koo and Kim Index estimated the severity and evolution of necrotic lesions in both groups. It indicated decline in the non-operated group (p=0.002) and improvement for operated patients (p=0.0002). DISCUSSION Core decompression had a favorable clinical and radiological outcome superior to surgical abstention. Stages I and II ONFH remained stable after drilling, necessitating no arthroplasty (considered as a failure of drilling). The Koo and Kim Index above 30 degrees in the non-operated group was a significant indicator of lesions degradation (p=0.002). In addition to the indolence obtained by core decompression, the benefit of drilling was manifested by the prolonging the adjournment before arthroplasty end-point. It was respectively 7.4+/-2.7 years in the operated group versus 2.6+/-2.4 years in the non-operated group (difference of 4.8 years, p<0.01). CONCLUSION The technique of core decompression remains a valid option place in the treatment sickle-cell disease avascular necrosis of the femoral head (ONFH). It may be especially recommended in under-equipped regions where drepanocytosis and its osteo-articular complications are frequent. LEVEL OF EVIDENCE Level III case-control therapeutic study.

Abstract
With the advent of cell-based therapies, biologics, and pharmaceuticals for the potential treatment of osteonecrosis, it is important to conduct evaluations using scientifically accepted outcomes measures. For the treatment of osteonecrosis, most studies have focused on pain relief, surgery, or the need for surgery, disease progression (advancing stage), and change in lesion size. Quantification of imaging techniques continue to gain in sophistication but have not yet been validated for use in clinical trials. Despite recent interest in using biomarkers or genetic markers in the diagnosis and analysis of disease progression, more research is needed to determine the sensitivity and specificity of these techniques with respect to osteonecrosis.

Abstract
Core decompression procedures have been used in osteonecrosis of the femoral head to attempt to delay the joint destruction that may necessitate hip arthroplasty. The efficacy of core decompressions has been variable with many variations of technique described. To determine whether the efficacy of this procedure has improved during the last 15 years using modern techniques, we compared recently reported radiographic and clinical success rates to results of surgeries performed before 1992. Additionally, we evaluated the outcomes of our cohort of 52 patients (79 hips) who were treated with multiple small-diameter drillings. There was a decrease in the proportion of patients undergoing additional surgeries and an increase in radiographic success when comparing pre-1992 results to patients treated in the last 15 years. However, there were fewer Stage III hips in the more recent reports, suggesting that patient selection was an important reason for this improvement. The results of the small-diameter drilling cohort were similar to other recent reports. Patients who had small lesions and were Ficat Stage I had the best results with 79% showing no radiographic progression. Our study confirms core decompression is a safe and effective procedure for treating early stage femoral head osteonecrosis.

Abstract
Sixty New Zealand rabbit models with steroid-induced necrosis of femoral head were exposed to a rotating permanent magnetic field (RPMF) (group A1-2 h/d for one month and group A2-2 h/d for two months), and the changes of femoral head, blood viscosity, serum cholesterol, triglyceride, and pressure within the hip joint cavity were measured and statistically analysed compared to that of control group (B1 and B2) and sham group (C1 and C2). After RPMF treatment, the osteogenesis regeneration of the necrotic femoral head was markedly improved, as was shown by micro-CT.
