Therapeutic Mechanisms of Action for Hyperbaric Oxygen on Femoral Head Necrosis
2018
Femoral head necrosis (FHN) is a disease process resulting from inadequate blood perfusion of subchondral bone. While the etiology of this disease is still not fully understood, there are multiple traumatic and atraumatic factors that are associated with the disease. Pathophysiology of the disease is characterized by the death of bone marrow and osteocytes. If left untreated, the disease may progress to joint collapse. While initial stages of the disease are asymptomatic, painful limitation of active and passive motion of the hip is eventually present. The current body of literature cannot identify an optimal treatment protocol for FHN. Postcollapse cases require surgical intervention, core decompression, or total hip arthroplasty. However, current strides in conservative management are being made. One of the possible conservative modalities that may effectively delay hip arthroplasty or even prevent the need for a surgical approach is hyperbaric oxygen (HBO 2 ) therapy. HBO 2 incre...
Hyperbaric oxygen therapy as a treatment for stage-I avascular necrosis of the femoral head
The Journal of Bone and Joint Surgery. British volume, 2003
A vascular necrosis (AVN) of the head of the femur is a potentially crippling disease which mainly affects young adults. Although treatment by exposure to hyperbaric oxygen (HBO) is reported as being beneficial, there has been no study of its use in treated compared with untreated patients. We selected 12 patients who suffered from Steinberg stage-I AVN of the head of the femur (four bilateral) whose lesions were 4 mm or more thick and/or 12.5 mm or more long on MRI. Daily HBO therapy was given for 100 days to each patient. All smaller stage-I lesions and more advanced stages of AVN were excluded. These size criteria were chosen in order to compare outcomes with an identical size of lesion in an untreated group described earlier. Overall, 81% of patients who received HBO therapy showed a return to normal on MRI as compared with 17% in the untreated group. We therefore conclude that hyperbaric oxygen is effective in the treatment of stage-I AVN of the head of the femur.
Hyperbaric Oxygen Therapy in Femoral Head Necrosis
The Journal of Arthroplasty, 2010
We evaluated hyperbaric oxygen (HBO) therapy on a cohort of patients with femoral head necrosis (FHN). This double-blind, randomized, controlled, prospective study included 20 patients with unilateral FHN. All were Ficat stage II, treated with either compressed oxygen (HBO) or compressed air (HBA). Each patient received 30 treatments of HBO or HBA for 6 weeks. Range of motion, stabilometry, and pain were assessed at the beginning of the study and after 10, 20, and 30 treatments by a blinded physician. After the initial 6-week treatment, the blind was broken; and all HBA patients were offered HBO treatment. At this point, the study becomes observational. Pretreatment, 12-month. and 7 year-follow-up magnetic resonance images were obtained. Statistical comparisons were obtained with nonparametric Mann-Whitney U test. Significant pain improvement for HBO was demonstrated after 20 treatments. Range of motion improved significantly during HBO for all parameters between 20 and 30 treatments. All patients remain substantially pain-free 7 years later: none required hip arthroplasty. Substantial radiographic healing of the osteonecrosis was observed in 7 of 9 hips. Hyperbaric oxygen therapy appears to be a viable treatment modality in patients with Ficat II FHN. Keywords: hyperbaric oxygen therapy, femoral head necrosis, hip arthroplasty.

Amaç: Femur başı avasküler nekrozu (AVN), femur başını besleyen damarların hasarlanması veya tıkanması sonucu ortaya çıkan kemik ve kemik iliği nekrozudur. Özellikle gençlerde ve orta yaşlarda görülen, büyük oranda cerrahi müdahale gerektiren bir hastalıktır. Cerrahideki gelişmelere rağmen bu hastalarda önemli oranda kalça protezi uygulaması gerekmektedir. Hiperbarik Oksijen Tedavisi (HBOT) tek başına veya cerrahi tekniklerle beraber femur başı avasküler nekrozunda bazı klinik olgularda başarılı sonuçları bildirilmiş bir tedavi yöntemidir. HBOT damar hasarına veya damar tıkanıklığına bağlı gelişen iskemik hastalıklarda da kullanılmaktadır. Enoksaparin pıhtılaşma sisteminde bulunan faktör Xaantagonistidir. Antikoagülan etkisinin yanında yapılan çalışmalarda kemik doku üzerinde osteopeni oluşturduğu, osteoblast gelişimini engellediği, osteoklast aktivitesini arttırdığı görülmüştür. Gereç ve Yöntemler: Bu çalışmada sıçanlarda deneysel olarak oluşturulan femur başı AVN'de HBOT ve Enoksaparinin etkinlikleri araştırılmıştır. Bu amaçla 64 sıçanın sol femur başlarına avasküler nekroz modeli uygulandı ve tedavilerin tek başına ve beraber uygulanmasının sonuçları araştırıldı. Bulgular: Çalışma sonucunda HBOT alan ve Enoksaparin tedavisi alan sıçanlarda yeni kemik yapımının arttığı, remodelizasyon ve kıkırdak değişikliklerinin kontrol grubuna göre daha az olduğu görülmüştür. Nekrotik dokuların temizlenme hızının HBOT ile arttığı görülmüştür. HBOT ile Enoksaparinin beraber uygulanmasıyla en iyi sonuçlara ulaşılmıştır. Sonuç: Bu çalışma HBOT'nin ve Enoksaparin tedavisinin tek başına veya kombine olarak femur başı AVN'de olumlu sonuçlar oluşturduğunu göstermektedir ve femur başı AVN hastalığı tedavisinde yapılan klinik çalışmaları desteklemektedir. Anahtar Kelimeler: Hiperbarik oksijen tedavisi, avasküler nekroz, enoksaparin Aim: Avascular necrosis of the femoral head (AVN) is the necrosis of the bone and the bone marrow resulting from the injury or the occlusion of the blood supplying vessels of the femoral head. Specially it is seen in mostly young and middle aged individuals and requiring mostly surgical procedures. Despite all advances in the surgical procedures, still a high rate of the hip prosthesis is a requirement in the treatment. Hyperbaric Oxygen Therapy (HBOT) alone or in combination with surgery is reported to be effective in some clinical AVN cases. HBOT is also a treatment method which is used in ischemic diseases resulting from vascular injuries or occlusions. Enoxaparin is an antagonist of factor Xa which is found in the coagulation system. Beside its anticoagulant effect it has been shown that it has an osteopenic effect, inhibits osteoblast maturation and increases osteoclast activity in the bone. Material and Methods: In this study effects of enoxaparin and HBOT were investigated in the treatment of experimentally formed AVN of the femoral heads of the rats. For this purpose, avascular necrosis model was applied to the left femoral heads of 64 rats and the results of the treatments alone and together were investigated. Results: In this study results have shown that an increase in the new bone formation, and remodelisation with less changes in the cartilage tissue than in the controls. An increase in the necrotic tissue clearing rate observed in the HBOT applied groups. The best results were achieved with the HBOT and enoxaparin combined applications. Conclusion: In this study HBOT alone, enoxaparin alone or combination of these two treatments have a positive effect in the experimental femoral head AVN and supporting the clinical studies in the femoral head AVN.

Background: Core decompression (CD) has been used in the treatment of pre-collapse stages avascular necrosis (AVN) with good results. Hyperbaric oygen therapy (HBO) was used as a non-invasive treatment for pre-collapse stages osteonecrosis with favorable results. This study aimed to compare the outcomes of HBO versus CD in stage II of non-traumatic AVN of the femoral head. Methods: Data were collected retrospectively for patients with non-traumatic AVN of the femoral head that was confirmed by MRI and underwent HBO or CD between January 2010 and December 2018, with a minimum follow-up of 12 months. Oxford Hip Score (OHS), radiographic progression, and Short-Form 12(SF12) were used to assess the outcomes. Results: Nineteen patients with 23 stage II AVN of the femoral head were included, 12 (52.2%) in CD, and 11 (47.8%) in the HBO group with an average follow-up of 34.2 ± 18.4 months. 66.7% of patients in CD and 81.8% in the HBO group achieved satisfactory hip function outcome with statistically significant mean Oxford Hip Score (35.8 ± 6.7 and 35.5 ± 5.1) (P 0.009 & .003) respectively. No statistical difference of OHS and SF12 (PCS &MCS) was found between the two groups (P 0.202, 0.128 & .670 respectively). Eight (34.7%) cases progressed to a higher radiological stage at one year follow-up. The rate of progression was not statistically significant between both groups (P 0.469) with no statistical difference of OHS and SF12 (PCS & MCS) in the progressed group (P 0.747, 0.648 & 0.416) respectively. Conclusion: This study showed that the HBO is promising and as effective as CD in the treatment of non-traumatic pre-collapsed AVN of the femoral head. Hence, HBO could be used as an alternative non-invasive treatment option.
Is Hyperbaric Oxygen Therapy Effective in Patients With Avascular Necrosis of the Femur Head?
Van Medical Journal, 2021
Avascular necrosis of the femoral head (AVNFH) is an irreversible disease, which usually causes osteoarthritis of the hip joint, especially in young people. Despite the fact that the reason for the onset of the pathological process has not been fully understood, it has been demonstrated that it can develop as a result of both traumatic and nontraumatic events (1). AVNFH has been defined as a pathological process caused by decreased blood Özet Amaç: Bu çalışmanın amacı, erken evre (Ficat Evre 1 ve 2a) femur başının avasküler nekrozu hastalarında atmosfer basıncının normalden üç kat daha yükseğe çıktığı basınçlı bir odada yüksek düzeyde oksijene maruz kalmanın (Hiperbarik Oksijen Tedavisi) klinik ve radyolojik sonuçlarını araştırmaktır.

Femoral condylar necrosis: treatment with hyperbaric oxygen therapy
Arthroplasty Today
Background: Osteonecrosis of the knee (ONK) is a form of aseptic necrosis resulting from ischemia to subchondral bone tissue. Typically, treatment is invasive. Hyperbaric oxygen therapy (HBOT) may provide a noninvasive alternative by improving oxygenation and reperfusion of ischemic areas. This study evaluates the efficacy of HBOT in a series of ONK patients. Methods: This retrospective study evaluates 37 ONK patients (29 male, 8 female; mean age ± 1 standard deviation: 54 ± 14); 83.7% of patients presented with Aglietti stage I-II; 16.3% presented with Aglietti stage III. Patients were treated with HBOT once a day, 5 days a week, at 2.5 atmosphere absolute with 100% inspired oxygen by mask for an average of 67.9 ± 15 sessions. Magnetic resonance imaging was performed before HBOT, within 1 year after completion of HBOT, and in 14 patients, 7 years after treatment. Oxford Knee Scores (OKSs) were recorded before HBOT and at the end of each HBOT treatment cycle. Results: After the 30 sessions of HBOT, 86% of patients experienced improvement in their OKS, 11% worsened, and 3% did not change. All patients improved in OKS after 50 sessions. Magnetic resonance imaging evaluation 1 year after HBOT completion showed that edema at the femoral condyle had resolved in all but 1 patient. Conclusions: HBOT is beneficial for treating ONK. Patients experienced improvements in pain and mobility as demonstrated by improvement in OKS. Radiographic improvements were also seen upon post-treatment follow-up. Aglietti staging for the entire sample saw an aggregate decrease (P < .01) from 1.7 ± 0.7 to 0.3 ± 0.6.

Efficacy of Adjunctive Hyperbaric Oxygen Therapy in Osteoradionecrosis
BioResearch Open Access, 2018
Osteoradionecrosis (ORN) is a common consequence resulting from radiation in patients with cancer. Presently, hyperbaric oxygen therapy (HBOT) is proposed to have a role in improving wound healing in ORN patients. There is no strong scientific evidence to confirm the benefits of HBOT for treatment of ORN as an adjunctive treatment.
