Effects of ozone on the pain and disability in patients with failed back surgery syndrome.

Introduction:: Low back pain is one of the painful disorders of higher prevalence. It has several etiologies and surgery may be indicated in the presence of neurological deficits or compression syndromes. However, in up to 40% of cases, patients develop worsening of pain and failed back surgery syndrome (FBSS), which is an important cause of chronic pain with high morbidity and disability.

Effects of ozone applied by spinal endoscopy in patients with chronic pain related to failed back surgery syndrome: a pilot study.

Introduction: In the last two decades, ozone has emerged as a treatment for low back pain, applied by means of minimally invasive techniques.

Objective: The aim of this study is to assess the effect and safety of ozone therapy applied in the epidural space for chronic pain related to failed back surgery syndrome.

Methods: The investigators studied 13 sequential patients of both sexes, between 18 and 70 years old, with persistent chronic pain (more than six months) in the lumbar region and in the lower limbs related to failed back surgery syndrome (FBSS).

[Surgical treatment of meralgia paresthetica: case report].

Meralgia paresthetica is characterized by pain, paresthesias or burning, and decreased touch and pain sensation on the anterolateral aspect of the thigh. It is due to neuropathy of the lateral femoral cutaneous nerve (LFCN). Conservative treatment is usually successful in relieving the symptoms in most of the patients.
