Abstract

Spinal stenosis is a narrowing of the spinal canal, the nerve root canals, or the neural foramina. The narrowing can be caused by the bony or soft tissue elements of the spinal canal or a combination of both. Spinal stenosis is a condition that has been understood relatively recently, having been brought to modern attention by Verbiest in 1949. His first article appeared in 1954 (Verbiest, 1954). The term spinal stenosis has been used to indicate stenosis of the entire cross-sectional area of the vertebral canal. The use of the term was based on the observation that stenosis of the central portion of the canal is almost always associated with stenosis of the lateral corners. However, the term central stenosis is used more frequently today.Crock coined the term nerve-root canal stenosis to indicate the isolated narrowing of the semitubular structure through which the nerve root runs from the thecal sac to the entrance of the intervertebral foramen; the term lateral stenosis is currently used to indicate this condition (Crock, 1981).Spinal stenosis includes primary, secondary and combined forms. Primary stenosis may be congenital, developmental. The Secondary stenosis may be degenerative, iatrogenic, spondylolytic, posttraumatic and others. Spinal stenosis may be present in isolation, with or without a disc bulge or herniation, or can be associated with degenerative spondylolythesis or degenerative scoliosis (Potacchini, 1999).In congenital and developmental stenosis the primary problem is one of an inadequate canal size. Normal canal size has been defined as a midsagittal diameter of more than 11.5 mm and an area more than 1.45cm. Although these measurements are useful as guidelines, symptoms do not always correspond to canal size; the degree of impingement on the neural element by the bony and soft tissues is more important (Kabins, 1994, 2002).Patients usually present with a history of an insidious onset of back, buttock, thigh, and calf pain. In the classic presentation, the patient describes a syndrome of neurologic claudication (Whiffen& Neuwirth, 1997). Radiographs showing decrease in the midsagittal diameter of the spinal canal and decrease in the interpedicular distance, due to short and thick pedicles (Kabins, 1994, 2002).There is conservative treatment which approved a good results for managing spinal stenosis which including: pharmacologic treatment, external support, manipulation, exercise, and traction.Operative treatment including decompressive laminectomy with its different procedures. May be including fusion and spinal instrumentation in the operative treatment (Kabins, 1994, 2002).
