A few of patients with lumbar disk herniation having a separation of clinical symptoms and signs and imaging features, can be found in clinic, but the traditional theory of direct mechanical compression of nerve roots by herniated nucleus pulposus can't be used to explain this abnormal protrusion of lumbar intervertebral disc. The clinical symptoms and signs of the atypical lumbar disk herniation are affected by multiple factors. The indirect mechanical compression and distraction effect of spinal nerve roots may play an important role in the occurrence of the separation, and the appearance of abnormal clinical symptoms and signs is closely related to the migration of herniated nucleus pulposus tissue, transmission of injury information in the nervous system, and the complex interactions among the nucleus pulposus, dural sac and nerve roots. Moreover,the changes of microcirculation and inflammation secondary to the herniated nucleus pulposus tissue, the hyperosteogeny in the corresponding segment of the lumbar vertebrae and the posture changes all results in a diversity of symptoms and signs in patients with lumbar intervertebral disc herniation. Besides, there exist congenital variation of lumbosacral nerve roots and vertebral bodies in some patients, and the misdiagnosis or missed diagnosis of imaging finding may occur in some cases. However, the appearance of a separation of clinical symptoms and signs and imaging examination in patients may be caused by a variety of reasons in clinic. The exact mechanism involved in the interaction among nucleus pulposus tissue, dural sac and nerve root, secondary changes of pathophysiology and biomechanics around the nucleus pulposus, the determination of lesioned responsible segments, and how to overcome the limitations of imaging all need the further researches.

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.

OBJECTIVETo summarize the therapeutic experience of Bryan prosthetic cervical disc replacement at the 3rd years after operation and to analyze the clinical effect, incidence rate of heterotopic ossification, conditions of prosthetic fusion in order to investigate the countermeasures.

METHODSFrom December 2005 to December 2008, 54 patients with cervical syndrome (34 males and 20 females, the age was from 39 to 69 years with an average of 50.5) were treated with single level Bryan prosthetic cervical disc replacement. The patients were followed for 24-36 months with an average of 30 months. The symptoms and nerve function were evaluated according to JOA and Odom's scoring. The anterior-posterior and lateral cervical X-ray films were also taken regularly every three months for the observation of heterotopic ossification and prosthetic fusion. Meanwhile, the X-ray films of the forward bending, extending, left and right lateriflection were taken before operation and at the 1st years after operation for the measurement of the stability and rang (ROM) of replaced levels.

RESULTSThe pain symptom and neurological function of all 54 patients were improved obviously. JOA score increased with an average of 76.1%, and ROM of replaced levels also improved obviously. The incidence rate of heterotopic ossification and prosthetic fusion went up year by year, 3.7% (2/54) for the first year, 16.7% (9/54) for the second year and 22.2% (12/54) for the nearly third year.

CONCLUSIONBryan prosthetic cervical disc replacement has better mid-stage results than conventional methods. Modified surgical methods and early rehabilitation exercise may reduce the relatively high incidence rate of heterotopic ossification and prosthetic fusion.

OBJECTIVE: To explore the curative effect of surgical treatment for lumbar discogenic low back pain. METHODS: Forty-two patients with lumbar discogenic low back pain were treated with disc excision and lumbar interbody fusion: 12 of them were treated with posterior lumbar interbody fusion (PLIF), 30 with afront lumbar interbody fusion (ALIF). The clinical results were evaluated by pre- and post-operative visual analogue scale (VAS), and the fusion rates of the lumbosacral spine were evaluated by X-ray. RESULTS: The average follow-up period was 18 months, ranging from 6 to 36 months. Low back pain basically disappeared in 11 patients treated with PLIF, with mild back pain in one patient; VAS after the operation decreased significantly in comparison with that preoperatively (P<0.01). Low back pain basically disappeared in 28 patients treated with ALIF; VAS after the operation decreased significantly in comparison with that preoperatively (P<0.01). The fusion rate was 90% in patients treated with PLIF, and 93% in patients with ALIF. CONCLUSION Disc excision and interbody fusion is effective in the treatment of lumbar discogenic low back pain, but the operation indications should be paid attention to.

OBJECTIVE: To explore the relationship between spinous process deviation and lumbar disc herniation in young patients. METHODS: From March 2015 to January 2022, 30 treated young (under the age of 30) patients with lumbar disc herniation were included as the young group. In addition 30 middle-aged patients (quinquagenarian group) with lumbar disc herniation and 30 patients with non-degenerative spinal diseases (young non-degenerative group) were selected as control groups. The angle of the spinous process deviation was measured on CT and statistically analyzed by various groups. All the data were measured twice and the average value was taken and recorded. RESULTS: The average angle of spinous process deviation in the degenerative lumbar vertebra of young patients were (3.89±3.77) degrees, similar to the (3.72±2.98) degrees of quinquagenarian patients(P=0.851). The average angle of s spinous process deviation young non-degenerative group were (2.20±2.28) degrees, significantly less than young group(P=0.040). The spinous process deviation angle of the superior vertebral of the degenerative lumbar in the young group was (4.10±3.44) degrees, which similar to the (3.47±2.87) degrees in the quinquagenarian group (P=0.447). A total of 19 young patients had the opposite deviation direction of the spinous process of the degenerative lumbar vertebra and upper vertebra, while only 7 quinquagenarian patients had this condition(P=0.02). The type of lumbar disc herniation in young patients had no significant relationship with the direction of spinous process deflection of the degenerative or upper lumbar vertebra (P>0.05). CONCLUSION Spinous process deviation is a risk factor of young lumbar disc herniation patients. If the deviation directions of adjacent lumbar spinous processes are opposite, it will increase the incidence of lumbar disc herniation in young patients. There was no significant correlation between the type of disc herniation and the deviation direction of the spinous process of the degenerative or upper lumbar vertebra. People with such anatomical variation can strengthen the stability of spine and prevent lumbar disc herniation through reasonable exercise.

OBJECTIVETo investigate the correlation of premature ejaculation (PE) with central lumber intervertebral disc herniation (CLIDH) and the pathogenesis of PE, and to search for a convenient, effective and non-invasive method for the treatment of PE.

METHODSA total of 263 selected PE patients underwent CT, and those that were found with CLIDH were randomized into a treatment group (n=180) and a control (n=60), the former treated by lumbar traction and the latter with sertraline hydrochloride tablets, both for 24 weeks. CIPE-5 scores of all the patients were analyzed, and the ejaculation latency and sexual satisfaction were recorded before and after the treatment.

RESULTSAmong the 263 PE patients, CLIDH was confirmed in 240 (91%). After the treatment, CIPE-5 scores, ejaculation latency and sexual satisfaction were markedly improved in the treatment group, with significant statistic difference from pre-treatment (P < 0.01). Significant differences were also observed between the treatment and the control groups after the treatment (P < 0.05), but not in the control group between pre- and post-treatment.

CONCLUSIONCLIDH may be one of the important causes of most "unexplainable" PE cases. And lumbar traction, non-invasive, highly effective and easily manipulable, has provided a new access to the diagnosis and treatment of the PE patients with CLIDH.
