Avascular Necrosis (AVN) of the Femoral Head is a pathologic process that results from interruption of blood supply to the bone. AVN of the hip is poorly understood, but this process is the final common pathway of traumatic or non-traumatic factors that compromise the already precarious circulation of the femoral head. Femoral head ischaemia results in the death of marrow and osteocytes and usually results in the collapse of the necrotic segment. This debilitating condition always causes severe hip pain and dysfunction. Preventing this serious condition is one of the concerned project of clinical study. The authors have reviewed and analysed 44 cases of femoral head AVN treated with FSN Acupuncture , and the result is positive and encouraging.

All 44 participants, who were diagnosed as AVN of the Femoral Head, had received FSN acupuncture treatments between July 2011 and June 2015. There were 21 males and 23 females, among them there were 61 hips involved in total. The ages of the participants were between 27 and 76, and the average age was 49. The courses of disease were between 10 months and 20 years, and the average course was 32 months. The shortest period of treatment was 1 month, and the longest was 15 months.

The treatment interventions: Find out ͞Huanji͟, the pathological tight muscles (PTM), which most commonly are the following muscles: Pectineus, Iliopsoas, Sartorius, Tensor Fasciae Latae, Gluteus Maximus, and Quadriceps etc. Insert FSN needle into the soft connective tissue layer around PTMs, then perform ͞Saosan͟—swaying manipulation and Reperfusion Approach—resistance exercise technique.

Outcomes: clinical recovered: 10 out of 44 (22.7%); effective: 21 out of 44 (70.5%); ineffective: 13 out 44 (29.5%).

Comprehension: FSN is a positive treatment of Femoral Head AVN, not only for easing off the symptoms but also for slowing down the deterioration process. Previous research has shown that Obturator, Lateral Circumfiex Femoral and Medial Circumfiex Femoral are the main arteries for the femoral head blood supply, and these blood vessels all go through the muscles surrounding the hip such as Pectineus, Iliopsoas, Sartorius, Tensor Fasciae Latae, Gluteus Maximus, and Quadriceps etc. If these muscles get pathological tightness as ͞Huanji͟ by some reason, they would compress the above arteries and result in the lack of blood supply to the femoral head and cause AVN. The stimulation of FSN to the soft connective tissue around the tight muscles can generate an electro-chemical effect and result in relaxing those muscles and reducing the pressure to the blood vessels, thence improving the blood supply to the femoral head and neck, and repairing the affected tissues and cells. Treatment combination with Reperfusion Approach technique also helps to release the tension of the tight muscles and reinforce the effect of FSN, results in relieving the pain and repairing the damage of the femoral head. In addition, patients don’t have to immobilize hip joint during the treatments, they can use their legs and hips for the weight-bearing exercise and activitiesof daily living, benefiting for their quality of life.
