AIM To investigate the effects of local and systemic administration of etanercept on the formation of epidural fibrosis. MATERIAL AND METHODS Twenty-eight rats were randomly divided into four equal groups (Control, SpongostanTM, Local etanercept and Systemic etanercept) and laminectomy was performed between T11 and L1 in all rats. SpongostanTM was soaked with saline (0.1 mg/kg), local etanerc...

The failed back surgery syndrome (FBSS) is a difficult diagnostic problem both clinically and radiologically. Forty-three patients were evaluated prospectively with magnetic resonance imaging (MRI) and forty-five scans were obtained. Fifteen patients (33%) showed recurrent disc prolapse; 15 (33%) patients postoperative epidural fibrosis; 8 (18%) both recurrent disc prolapse and epidural scarrin...

AIM Lumbar epidural fibrosis is increasingly recognized as a cause of persistent back pain. The aim of this study was to examine the effect Ankaferd Blood Stopper on epidural fibrosis following laminectomy in rat models. MATERIAL AND METHODS Twenty Sprague-Dawley male rats were randomly allocated to 2 groups of 10 each. The dura mater and nerve root were exposed after L1 unilateral laminectom...

AIM One of the most important causes of failed back surgery is the development of epidural fibrosis. Many methods and substances have been used to prevent the development of epidural fibrosis after laminectomy. In this study, effects of "manuka honey" on epidural fibrosis development after laminectomy was evaluated in rats. MATERIAL AND METHODS Subjects were divided into two groups:In Group-1...

BACKGROUND CONTEXT Postsurgical epidural adhesions and fibrosis after surgery for lumbar disc herniation are a consequence of normal wound healing. The presence of fibrosis renders reoperations risky, and in some patients fibrosis may lead to nerve root tethering. PURPOSE One approach to minimizing the risk of developing epidural adhesions is to provide a barrier between the dural membrane an...

BACKGROUND The aim of this experimental study was to investigate the effectiveness of intramuscular pentoxifylline in the prevention of postoperative fibrosis. MATERIAL/METHODS We divided 16 adult Wistar albino rats into 2 equal groups: treatment and control. Both groups underwent L1 vertebral total laminectomy to expose the dura. The intramuscular treatment group received pentoxifylline. Fou...

Epidural fibrosis is a contributing factor to the persistent pain that is associated with failed back surgery syndrome (FBSS) and other pathophysiologies, particularly as it inhibits the passage of regional medications to areas responsible for pain. Therefore, effective mechanical detachment of epidural fibrosis can contribute to pain reduction and improve function in FBSS patients. In this rep...

Tacrolimus (FK506) has been demonstrated to reduce epidural fibrosis. However, the detailed mechanism of action has not been elucidated. Aberrant miR-429 is involved in many diseases. The aim of this study was to describe the exact mechanism of FK506 induced apoptosis in fibroblasts and the prevention of epidural fibrosis. FK506 induced fibroblast apoptosis was evaluated using CCK-8 assays, flo...

BACKGROUND The association between epidural fibrosis and recurrent symptoms after lumbar spine surgery remains a matter of debate in scientific literature and the underlying pathophysiological mechanism has not been clearly elucidated. OBJECTIVE To investigate the presence of nerve fibers and the expression of osteopontin in epidural fibrous tissue after lumbar surgery in humans. STUDY DESI...

BACKGROUND Epidural fibrosis often causes serious complications in patients after lumbar laminectomy and discectomy and is associated with the proliferation of fibroblasts. Suramin is known to have an obvious inhibitory effect on the coactions of many growth factors and their receptors, but little was previously known about the effect of suramin on fibroblast proliferation and the progress of e...
