Core decompression and grafting has been shown to relieve pain and possibly prevent disease progression in patients with symptomatic osteonecrosis (ON) of the hip. However, there is a lack of evidence regarding the management of the asymptomatic hip with femoral head ON. The purpose of this study was to evaluate the outcome of core decompression in the asymptomatic hip with ON. We prospectively followed 37 consecutive patients with MRI confirmed ON of the hips that underwent simultaneous bilateral core decompression and bone grafting. Prior to surgery, only one of the hips was symptomatic, and the main indication for surgical decompression of the asymptomatic side was to prevent disease progression. No hip on the asymptomatic side was staged greater than Steinberg IIB classification. Serial radiographs were followed for evidence of disease progression. Six patients were lost to follow-up prior to two years. The remaining 31 patients were followed for an average of 32.6 months. There were 20 men and 11 women with an average age of 40.6 years. Ten patients with asymptomatic hips at the time of surgical decompression had disease progression requiring THA. The mean time to arthroplasty in this group was 15.1 months. Meanwhile, 13 symptomatic hips at the initial surgery progressed to THA at an average of 12.9 months following core decompression. The proportion of hips requiring conversion to THA was similar between the two groups (p=0.30), and the rate of progression to THA was not significantly faster compared to patients with symptomatic hips who subsequently required THA (p=0.18). Core decompression for asymptomatic ON of the femoral head is unpredictable. Based on our results, asymptomatic ON lesions particularly in the setting of bilateral disease should be closely observed and surgery reserved for when symptoms arise.

Abstract Background: To explore the clinical effect of robot-assisted core decompression combined with bone grafting in the treatment of femoral head necrosis involved in early stage.Methods: This study is a prospective cohort study. The study included 49 patients (78 hips) who attended the Department of Orthopedics and Joint Surgery of the Second Affiliated Hospital of Xi'an Jiaotong University from August 2019 to February 2021. All the patients suffering Association Research Circulation Osseous (ARCO) II stage of femoral head necrosis underwent core decompression and bone grafting. Among the patients undergoing surgery, 30 patients (54 hips) were treated with traditional surgical methods, and 19 patients (24 hips) were assisted by the made-in-China orthopedic robot system. All operations were performed by the same operator. The baseline data of the two groups of patients, the time of unilateral operation, the number of unilateral X-ray fluoroscopy, the Harris hip score (HHS) at the last follow-up after surgery, the visual analog score (VAS), and the collapse rate at the last follow-up were collected and compared. Results: A total of 41 patients (70 hips) were followed up, including 24 cases (42 hips) in the traditional surgery group and 17 cases in the robot-assisted group (28 hips). The average follow-up time of all cases was (13.9±3.4) months (range: 8-18 months). At the last follow-up, a total of 13 patients (13 hips) suffered femoral head surface collapse, including 11 patients in the traditional surgery group (11 hips) and 2 patients in the robot-assisted group (2 hips). The rate of femoral head collapse between the two groups had statistical difference. The average operation time of unilateral hip in the traditional operation group was (22.5±5.5) min, and (18.2±4.0) min in the robot-assisted group, with significant difference. The number of X-ray fluoroscopy of unilateral hip in the traditional operation group was (14.7±3.1) times, and (10.1±3.1) times in the robot-assisted group, with significant difference. The HHS before surgery in the traditional surgery group was (63.8±3.2) points, and (84.6±3.4) points at the last follow-up,while the preoperative HHS of the robot-assisted surgery group was (65.5±3.5) points, and (85.9±3.1) points at the last follow-up. The HHS at the last follow-up of the two groups were significantly different from those before the operation, but there was no difference between the two groups. The preoperative VAS of the traditional surgery group was (4.8±0.8) points, and (1.7±1.2) points at the last follow-up. The preoperative VAS of the robot-assisted surgery group was (5.0±0.7) points, and (0.9±0.7) points at the last follow-up. At the last follow-up of the two groups, there were significant differences in VAS, and significant difference between the two groups was also detected.Conclusion: Core decompression combined with bone grafting have a definite effect in the treatment of femoral head necrosis at early stage. Compared with traditional surgery, robot-assisted surgery can achieve better short-term results and head preservation rate.

Abstract BackgroundTo report the outcomes of the single approach to double-channel core decompression and bone grafting with structural bone support (SDBS) for osteonecrosis of the femoral head (ONFH) and define the indications.MethodsOne-hundred-and-thirty-nine hips in 96 patients (79 males, 17 females; mean age 37.53±10.31 years, range 14–58 years; mean body mass index 25.15±3.63 kg/m2) were retrospectively analysed. The Harris hip score (HHS) was used to assess hip function, and radiographs were used to assess the depth of femoral head collapse. Treatment failure was defined as the performance of total hip arthroplasty (THA). The variables assessed as potential risk factors for surgical failure were: aetiology, Japanese Osteonecrosis Investigation Committee (JIC) type, age, and Association Research Circulation Osseous (ARCO) stage. Complications were recorded.ResultsThe HHS increased from 79.00±13.61 preoperatively to 82.01±17.29 at final follow-up (P=0.041). The average HHS improvement was 3.00±21.86. The combined excellent and good rate at final follow-up (65.6%) was significantly higher than that before surgery (34.5%) (P=0.000). On radiographic evaluation, 103 (74.1%) hips remained stable, while 36 (25.9%) had femoral head collapse or aggravation of ONFH. THA was performed in 18 hips. Thus, the overall femoral head survival rate was 87.05% (121/139). The success rate was adversely affected by JIC type, but not by aetiology, age, or ARCO stage. The only complication was a subtrochanteric fracture in one patient.ConclusionThe SDBS effectively delays or even terminates the progression of ONFH, especially type B and C1. The SDBS is a good option for early-stage ONFH.

Background: Avascular necrosis (AVN) is defined as cellular death of bone components due to interruption of the blood supply; the bone structures then collapse, resulting in bone destruction, pain, and loss of joint function. AVN is associated with numerous conditions and usually involves the epiphysis of long bones, such as the femoral head. In clinical practice, AVN is most commonly encountered in the hip. Early diagnosis and appropriate intervention can delay the need for joint replacement. However, most patients present late in the disease course. Without treatment, the process is almost always progressive, leading to joint destruction within 5 years.Treatment of a vascular necrosis depends mainly on early diagnosis which mainly based on clinical findings, x-ray finding & MRI.A variety of non vascularized bone grafting techniques have been proposed with varying degrees of success as treatment alternatives for osteonecrosis of the femoral head. The success of these procedures may be enhanced using ancillary growth and differentiation factors. Objectives: To treat non traumatic hip osteonecrosis by non vascularized bone graft versus core decompression. Type of the study: A retrospective study. Methods: We retrospectively reviewed 72 patients (88 hips) with osteonecrosis of the femoral head between May 2009, and March 2014,divided into two groups . Group A include 34 patients (44 hips) with osteonecrosis of the femoral head who had non vascularized bone grafting procedures done for them . Minimum follow-up was 12 months. We compared the outcomes in this cohort to similar hip number (44 hips) in 40 patients treated with core decompression only (group B). We used Phemister technique to make a window at the posterior aspect of greater trochanter to remove necrotic bone and packed the excavated area with autogenous cancellous bone graft taken from ipsilateral iliac crest or leave it without bone graft (decompression only). Results: We report the result of treatment for femoral head avascular necrosis depending on Ficat classification stage I, II, & III. The minimum follow up was 12 months (12m-36m). The success percentage of hips in our cohort of patients with non vascularized bone grafting group A are 86% (38 of 44 hips), which is higher than group B 63% (28 of 44 hips) with core decompression alone. Conclusions: These procedures core decompression and autogenous cancellous bone graft may defer joint arthroplasty in selected patients & it is more effective than core decompression alone in treating early stages of femoral head osteonecrosis.

Abstract Background Core decompression and nonvascularized bone grafting are used in the early stage of osteonecrosis of femoral head for a period. Since the comparison of the core decompression and nonvascularized bone grafting are less reported, the purpose of our study was to investigate the clinical outcomes of two procedures in patients with earlier stages of the osteonecrosis of femoral head. Methods Between January 2018 and January 2019, 46 patients (48 hips) are divided into core decompression group and non-vascularized allogeneic fibula grafting group according to their procedures. The mean follow-up were 28.31±3.7 months (24–36 months) and 29.23±4.7months(24–36 months) respectively. the primary outcomes were VAS and HHS. Survivorship was analyzed with the collapse of femoral head or conversion to total hip arthroplasty (THA) as the endpoint. Results At the final follow-up, two hips underwent THA in core decompression group and three hips in non-vascularized allogeneic fibula grafting group. The radiographic survival rates are 76.9% and 77.3% in the two groups. Statistically significant improvements were seen in both groups on the VAS and HHS. The radiographic survival rate of hips was significantly inferior in lateral type lesion (P = 0.03; CI,0.765–2.114) and ARCO III stage (P = 0.28; CI, 1.254–58.752) in core decompression group. ARCO III stage (P = 0.02; CI, 1.351–49.344) and BMI>25 (P = 0.35; CI, 0.999–2.131) were independent risk factors for the collapse of femoral head in non-vascularized allogeneic fibula grafting group. Conclusion In this study, two procedures all can reduce the patient’s pain and improve functional activity. Arco stage III is a common risk factor for the collapse of femoral head in both groups. lateral lesion and BMI>25 are risk factors for the collapse of femoral head in core decompression group and non-vascularized allogeneic fibula grafting group, respectively. Both groups had good hip survival rates during the follow-up period.

Background: Avascular necrosis of the femoral head is a severe disease and causes osteoarthritis of the hip joint in young adults. Early diagnosis leads to better prognosis and therapeutic success. Aim: To study pain, radiological outcome & functional outcome post hip forage procedure in patients of avascular necrosis of head of femur (Ficat and Arlet grade 1 and grade 2A). Study Design: This was a prospective observational study. Place and Duration of Study: Conducted in the Department of Orthopaedics, Dr. D.Y. Patil Medical College, Hospital and Research Centre, Nerul, Navi Mumbai over a period of 2 years from 2015 to 2017 Methodology: We included 50 patients (39 males, 11 females) with Avascular necrosis of unilateral or bilateral head of femur (Grade 1 and Grade 2A), clinical, radiological and functional(with the help of Harris hip score) examination was done at 6 months and 12 months follow up post operatively.  Results: Out of the 50 patients, pre-peratively, 60% reported moderate pain, 20% mild pain and 20% severe pain. At follow-up, 36% patients reported slight pain, 26% mild pain, 26% moderate pain, 8% marked pain, and no pain was reported by 4% patients. Pre-operatively, no limp was seen in 34% patients, while 66% patient had a limp. At follow-up, 70% patient had a limp and no limp in 30% patients. Before surgery, support (cane use) was required by 6% patients, while at follow-up, support was noted by 12% patients. Preoperative mean Harris Hip Score was 63.6, while that at follow-up it was 74.74. Radiological worsening of the disease occurred only in 38% of the patients which suggests that disease progression was delayed in most patients(62%). 2% patients had a complication of foot drop. Conclusion: Avascular necrosis of femoral head is more common in young males. Core decompression by multiple drilling and/or core decompression with fibular strut grafting are equally effective in pre collapse stages (stage 1 and stage 2A) with better functional and radiological outcomes and hence these procedures can play a vital role in delaying the disease progression.

Introduction: The aim of this study was to report the clinical and radiological outcomes for 21 patients (28 hips) treated for osteonecrosis of the femoral head using the lightbulb technique, a nonvascularised bone grafting technique. Methods: The study group included 14 men and 7 women, with a mean age of 33.2 (range 22-50) years, presenting with avascular necrosis of the femoral head of stage 4a or earlier, according to the Steinberg classification. Patients were treated using the nonvascularised lightbulb bone grafting technique. The primary clinical outcome was the Harris Hip Scores (HHS), while primary outcomes of treatment effectiveness and disease progression were based on radiographic evidence of disease progression and the need for total hip replacement. The rate of treatment success and failure was evaluated using the Kaplan-Meier survival analysis. Results: The mean HHS increased from 52.66 to 74.33 after treatment, with excellent-to-good outcomes obtained in 21 (75%) of the cases. Fair-to-poor results were obtained in 7 (25%) of the cases, with total hip arthroplasty subsequently required in 5 of these cases. The radiological failure rate was 50% among cases treated in Steinberg stage 1 (1/2), 42% in stage 3 (5/12), and 100% in stage 4 (2/2). Conclusions: The lightbulb technique can provide a clinically acceptable rate of successful treatment of osteonecrosis of the femoral head when used in the early stages of the disease, prior to collapse of the femoral head.

Introduction: Carbon monoxide poisoning may occur in several contexts.Material and Methods: Retrospective of 37 carbon monoxide poisoning cases that underwent hyperbaric oxygen during wildfires in Funchal in August 2016.Results: The studied sample included 37 patients, mean age of 38 years, 78% males. Ten were firefighters, four children and two pregnant victims. Neurological symptoms were the most reported. Median carboxyhemoglobin level was 3.7% (IQR 2.7). All received high-flow oxygen from admission to delivery of hyperbaric oxygen. Persistence of symptoms was the main indication for hyperbaric oxygen. Median time to hyperbaric oxygen was 4.8 hours (IQR 9.5), at 2.5 ATA for 90 minutes, without major complications. Discharge in less than 24 hours occurred in 92% of the cases. Thirty days follow-up: five patients presented clinical symptoms of late neurological syndrome; twelve patients were lost to follow-up. Carboxyhemoglobin levels on admission and mean time to hyperbaric oxygen were no different between those who did and did not develop the syndrome at 30 days (p = 0.44 and p = 0.58, respectively).Discussion: Late neurological syndrome at 30 days occurred in 20% and no new cases were reported at 12 months.Conclusion: Use of hyperbaric oxygen appears to have reduced the incidence of the syndrome. This seems to be the first Portuguese series reporting use of hyperbaric oxygen in carbon monoxide poisoning due to wildfires. The authors intend to alert to the importance of referral of these patients because the indications and benefits of this treatment are well documented. This is especially important given the ever-growing issue of wildfires in Portugal.
