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.

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.

OBJECTIVETo explore clinical presentations and the operational opportunity of traumatic cervical disc herniation.

METHODSFrom June 2002 to June 2009,40 patients with traumatic cervical disc herniation were treated. There were 24 males and 16 females, with an average age of 43.2 years old ranging from 30 to 56 years. There were 36 patients with single intervertebral disc herniation and 4 patients with double. The injury level of those patients were at C3,4 in 16 cases, C4,5 in 10 cases, C5,6 in 12 cases and C6,7 in 6 cases. Among them, 18 patients showed spinal cord signal changes by MRI, 5 patients suffered from nothing but neck and shoulder pain, 8 patients with nerve root stimulation; 10 patients with spinal cord compression, and 17 patients had both nerve root stimulation and spinal cord compression symptoms. Conservative treatment were applied to 13 patients with neck and shoulder pain and nerve root stimulation, 5 cases of which were transferred to operation in case of poor effects, and Odom criteria were used to assess operational effects. Twenty-seven patients with spinal cord compression accepted operation from 1 to 27days after their trauma, 16 of which were operated in 5 days (early operational group with an JOA score of 11.3 +/- 2.8), other 11 cases were operated from 5 to 27 days (delayed operational group with an JOA score of 11.4 +/- 2.9 ), then functional assessment of spinal cord were assessed according to JOA criteria.

RESULTSThree patients who were transferred from conservative treatment recovered excellently according to Odom criteria and the other 2 were good at final followed-up. JOA score of early operational group increased from (11.3 +/- 2.8) to (15.3 +/- 1.8) one week after operation (P < 0.01), and (15.9 +/- 1.4) at final followed-up (P < 0.01). JOA score of delayed operational group increased from (11.4 +/- 2.9) to (14.0 +/- 2.6) one week after operation (P < 0.01), and (15.3 +/- 1.5) at final followed-up (P < 0.01). The recovery ratio of JOA score of early operational group were (74.6 +/- 16.8)% 1 week after operation,and increased to (85.6 +/- 13.6)% at final followed-up; while that of delayed operational group were (50.9 +/- 17.5)% and (68.2 +/- 21.5)%, and there were significant difference between early operational group and delayed operational group both at 1 week postoperation and final followup (P < 0.05).

CONCLUSIONThere are some difference in pathological segment and imaging manifestation between traumatic cervical disc herniation and cervical spondylosis. Early operation is favorable to the recovery of neurological function in patients with spinal cord compression.

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.
