Objective To investigate the value of posterior short segment peg-stick system plus pediele screw fixation in treatment of thoracolumbar fractures. Methods There were 38 patients invol-ving fractures at Tn in three patients, at T_(12) in 11, at L_1 in 15 and at L_2 in nine. There were three pa-tients with simple fractures of vertebral compression, 35 with burst fractures, 33 with thoracolumbar frac-tures combined with paraplegia. The patients with simple fracture of vertebral compression were treated by posterior short-segment peg-stick system plus pedicle screw fixation. While the patients with paraplegia and intraspinal occupancy were treated by posterior decompression, vertebral enlargement and bone graft-ing (between zygopophysis and transverse process) after fixation. Results All patients received a fol-low-up for average 14.5 months, which showed accurate position of pedicle screw and fine contour of the injured vertebra after reduction, with no loosening or breakage of fixators, chronic lumbar pain or loss of the height of fractured vertebra. Of all, 33 patients were accompanied by paresis. There was one patient at Grade A, six at Grade B, 16 at Grade C and nine at Grade D before operation. But there was one pa-tient at Grade A, one at Grade B, five at Grade C, 10 at Grade D and 16 at Grade E. Conclusions For thoracolumbar fractures especially vertebral burst fractures, posterior short segment speg-stick system plus pedicle screw fixation is an ideal treatment method, for it has the following advantages: no obvious loss of the height of the vertebra after operation, protection of the intact intervertebral disc under the in-jured vertebra and minor effect on range of motion of the lumbar vertebrae.

Objective To investigate the effect of intrarectal local anesthesia (IRLA) with heated oxybuprocaine gel on pain during transrectal ultrasound guided prostate biopsy (TRUSPB).Methods A total of 150 cases patients who underwent TRUSPB in Huzhou Central Hospital from January to June 2023 were prospectively taken into.The patients were randomly divided into group A (routine group),group B (oxybuprocaine gel for IRLA at room temperature) and group C (oxybuprocaine gel for IRLA at 40℃),with 50 cases in each group.Nurses who were unaware of the anesthesia type used visual analog scale (VAS) to score the pain level of patients at each stage (VAS Ⅰ:when the ultrasound probe was inserted into the rectum;VAS Ⅱ:during the biopsy;VAS Ⅲ:30 minutes after biopsy),and the incidence of complications after biopsy were compared.Results The VAS Ⅱ score of group C was lower than that of group A and group B,and the difference was statistically significant (P<0.05).There was no statistically significant difference (P>0.05) in the VAS Ⅰ,VAS Ⅲ scores,and incidence of complications after biopsy among the three groups.There was no allergic reaction to oxybuprocaine gel.Conclusion In TRUSPB,IRLA with heated oxybuprocaine gel can effectively control pain without increasing incidence of complications.
