Objective To investigate the pathological and physiopathological difference between the ruptured” and the “degenerated” typed lumbar disc herniation (RDH and DDH) by measurement of the pressure of the herniated lumbar disc both in the herniated site and in the nucleus pulposus during the surgery, combined with the clinical,light microscopical and immunohistochemical properties. Methods Fifty seven cases of lumbar disc herniation undergone operation in the Tianjin Medical University Hospital were included in this study. The patients were divided into 2 groups. 1) Rupture typed lumbar disc herniation in which the herniated chip of the lumbar disc separated from the parent disc and was squeesed or drew out easily when the superficial posterior longitudenal ligament and anulus fibrosis were opened in the herniated site. 2) Degenerated typed lumber disc herniation in which no herniated chip of the lumber disc escaped; the herniated material can not be taken out unless the disc was resected by the instrument. Before the herniated disc was incised, the intervertebral disc pressure was measured using GENERAA710 multifunctional monitor. Both the light microscopical and the immunohistochemical difference between the RDH and the DDH was studied. Results 1) In the herniated site, the pressure in the RDH is higher than that in the DDH(P0.05). 3) In the RDH, the pressure in the herniated site is higher than that in the nucleus pulposus (P0.05). 5) The“lumbar pain score”and the pressure have obviously relationship in all of 35 patients(r=0.539,P

Objective To introduce laminar shelling decompression technique and to discuss its benefit for decompression of thoracic ossification of ligamentum flavum. Methods 102 patients were diagnosed as thoracic ossification of ligamentum flavum, 63 males and 39 females with an average age of 49.7 years (range, 33 to 71 years). 99 cases suffered with sensation disturbance, 73 cases with constriction on trunk or lower limbs, 77 cases with sphincter dysfunction. The IMSOP Standard Neurological Classification of Spinal Cord Injury was applied for localized the level of thoracic spondylopathy. The JOA lower limb motor function standard and sphincter function standard were used to evaluate the ability of lower limb motion and sphincter function respectively. In the decompression the dorsal cortex of lamina was the first layer to resect, the facet joint surface indicate the depth for removing the second layer, then thinning the ossified tissue by shaving with the motor bur until it was somewhat lucent. Finally decompress the spinal canal by moth eaten manner. Results The mean decompression length was 2.8 lamina(2 to 4 lamina). The mean follow-up duration was 18.9 months (3 to 41 months). Among 99 sensation disturbance 69 totally recovered, 30 relived. 73 cases with the feel of constriction of trunk or lower limbs were completely recovered. Postoperative JOA sphincter function score was 2.632?0.407, comparing with the preoperation score, and the difference was significant (t=15.93, P
