OBJECTIVETo investigate the operative management and surgical techniques for lumber disc herniation (LDH) in aged patients (>or=65 years).

METHODSFrom 2005 to 2010,the data of 43 patients with LDH underwent surgical treatment were retrospectively analyzed. There were 25 males and 18 females,aged from 65 to 70 years old with an average of 67.6 years. The course of disease was from 6 weeks to 7 years with an average of 10.2 years. Fenestratiodn discectomy or extended fenestration discectomy and unilateral or bilateral fenestration were used according to the conditions of location,type of herniated macleos polposus and nerve root compression. Among the patients,the nerve root canal was enlarged,hyperplastic osteophyma and soft tissue were removed, bilateral articular process was reserved in order to maintain the stability of the lumbar segment.

RESULTSAll the patients were followed up from 1.2 to 5.2 years. According to the criteria of HU you-gu, 25 cases got excellent results, 15 good, 2 fair and 1 poor. No infection or nerve injury was found. Nerve function of patients had a normal or near normal recovery.

CONCLUSIONFor the treatment of LDH in aged patents,it is key that reasonably choose the operative method, completely remove the hyperplasy of diseased region and enlarge the nerve root canal, thoroughly loose the nerve root.

Compared with open surgery, percutaneous transforaminal endoscopic discectomy (PTED) for lumbar disc herniation (LDH) has advantages of minamilly invasive, little impact on stability of spine and rapid recovery. However, PTED by transforaminal approach has relatively limited indications and can not completely replace open surgery, due to different location of migrated herniated fragment, the level of pathological segment or presence of a high iliac crest. Development of new approach and ancillary equipment have become the focus and future direction of PTED. In recent years, interlaminar and transiliac approach extended the indications of PTED greatly. However, not-standard manipulation, improper selection of indications or surgical approach has been attributed to the main reason for failure in PTED surgery. In view of this, the paper summaries indications, different approaches and methods, clinical efficacy and complications of PTED.

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

Dynamic stabilization system plays an important role in the treatment of the degenerative lumbar spine. Fusion of short movement segments has little influences on the motion of lumbar spine. Meanwhile, preservation of movements of segment can prevent the degeneration of adjacent segment and maintain the possibility of disc replacement even under the condition that facet joints need to be excised. While maintaining the normal lumbar motion, dynamic stabilization system can not only decrease the load of intervertebral disc of corresponding movement segments and provide a good environment for the recovery of intervertebral disc and soft tissues, but also delay the degeneration of small facet and reconstruct the biomechanical function of spine.

OBJECTIVETo explore a operative approach and its effect to the central protrusion of lumbar intervertebral disc.

METHODSFrom February 1999 to December 2005,34 patients with central protrusion of lumbar intervertebral disc were treated with an improved operative procedure. The study involved 25 males and 9 females with an average of 46.4 years (range, 35 to 63 years). The involved level of herniation were at L4,5 in 20 cases and L5S1 in 14 cases. Pains happened on one leg fixedly and seriously with another lightly in 21 cases, on one leg initially and lightly with another seriously later in 8 cases, on bilateral legs alike in 5 cases. Preoperative CT film showed central type in 8 cases and laterocentral type in 26 cases. The corresponding spinous process was resected on the basis of unilateral fenestration. The supraspinous ligament was retained and pulled to the opposite side for revealing spinal canal, and then diskectomy was done. The above procedure was named "fenestration with the spinous process resection".

RESULTSAll the 34 patients were followed up for 1 to 5 years. The outcome was evaluated according to the standard of HOU Shu-xun, 20 cases were excellent, 11 good and 3 fair. The total rate of excellent and good was 91.2%.

CONCLUSIONThe "fenestration with the spinous process resection" not only completed decompression of spinal canal and diskectomy, but also retained opposite lamina and supraspinous ligament and maintained the stability of posterior vertebral column, which are a new improved approach for the central protrusion of lumbar intervertebral disc.

There has been rapid progress in endoscopy-and imaging technology-based minimally invasive surgery for the treatment of lumbar disc herniation (LDH). It is advategeous over conventional surgery in that it not only reduces surgical trauma but relieves sufferings of patients. However, endoscopy-and imaging technology-based minimally invasive surgery cannot completely replace traditional surgery at present because of its limited indications. How to expand the indications and solve the practical problem of lumbar reconstruction remains to be the direction of future breakthrough. This article is a summary of the progress and current situation of minimally invasive percutaneous and endoscopic techniques for the treatment of LDH.
