ABSTRACT
<p><b>OBJECTIVE</b>To study effect of shoulder joint function after rotator cuff repair of polylactic acid absorbable membrane.</p><p><b>METHODS</b>From September 2015 to December 2016, 50 patients diagnosed with rotator cuff tear were selected and divided into treatment group and control group. There were 25 patients in control group, including 12 males and 13 females, with an average age of (48.7±3.5) years old, who received simple arthroscopic rotator cuff repair. There were 25 patients in treatment group, including 11 males and 14 females, with an average age of(49.2±4.1) years old, who performed arthroscopic rotator cuff repair with implanting polylactic acid absorbable membraneon shoulder of rotator cuff. Preoperative and postoperative VAS score, ASES score and UCLA score were recorded and compared between two groups.</p><p><b>RESULTS</b>At 6 months after operation, preoperative VAS score in control group was 5.48±1.12, and decreased as 1.28±0.84 after operation; ASES score before operation was 52.24±4.64, and improved to 86.92±3.20 after operation;preoperative UCLA score improved from 14.36±1.89 before operation to 30.72±1.28 after operation. In treatment group, VAS score decreased from 5.36±1.32 before operation to 1.40±0.71 after operation;preoperative ASES score was 51.04±4.09, and improved to 88.96±2.79 after operation; UCLA score improved from 15.12±1.81 before operation to 32.12±1.33 after operation. There was no significant difference in VAS score between two groups, and ASES score, UCLA score in treatment group was obviously better than control group.</p><p><b>CONCLUSIONS</b>Application of polylactic acid absorbable medical membrane could obviously improve shoulder function, and effectively prevent acromion adhesion after arthroscopic rotator cuff repair.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical effects of over 5 year follow up of unilateral pedicle screw fixation with transforaminal lumbar interbody fusion(TLIF) in treating lumbar degenerative diseases.</p><p><b>METHODS</b>The clinical data of 24 patients with lumbar degenerative disease underwent unilateral pedicle screw fixation with transforaminal lumbar interbody fusion from March 2007 to October 2009, were retrospectively analyzed. There were 13 males and 11 females, aged from 34 to 68 years old with an average of 52 years. Postoperative pain and functional results were analyzed by the visual analogue scale(VAS) and Oswestry Disability Index(ODI). Radiological examination was obtained for each patient to assess the height of intervertebral space, postoperative intervertebral fusion conditions and general complications.</p><p><b>RESULTS</b>All patients were followed up from 5 to 8 years with an average of 6.7 years. VAS scores of low back pain and leg pain decreased from preoperative 7.82±0.71, 8.42±1.24 to postoperative 1.87±0.81, 2.23±1.62, respectively(<0.05). ODI decreased from preoperative(53.42±8.26)% to postoperative(12.45±7.67)%(<0.05). Postoperative intervertebral space height in different segments were improved than preoperative(<0.05), but in final follow up it was decreased than 3 months after operation(<0.05). There was no significant difference in the postoperative intervertebral space height between the operated side and non operated side. But at final follow up, the intervertebral space height of non operated side was obviously loss. At final follow up, the fusion rate was 95.8%. The incidence of adjacent segment degeneration was 45.8%. The paraspinal muscle fibrosis incidence was 8.3%. No complications such as secondary scoliosis, intervertebral height loss, cage slippage, screw loosening and internal fixation breakage were found.</p><p><b>CONCLUSIONS</b>Unilateral pedicle screw fixation with TLIF is a satisfactory method and can obtain good effects in treating lumbar degenerative diseases according to over 5 year follow up, however, its indications should be well considered. But the problems such as intervertebral space height of operated side loss and adjacent segment degeneration after unilateral pedicle screw fixation need further clinical study.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate curative effect of the fibrinogen gel for treating sacral canal arachnoid cyst.</p><p><b>METHODS</b>Nineteen patients with sacral canal arachnoid cysts included 7 males and 12 females; The average age was 48.4 years ranging from 19 to 68 years. The course was from 2 weeks to 7 months. Of all the patients, 9 were in level of S1, 4 were in level of S1 to S2, 5 were in level of S2, 1 was in level of S1 to S3. Cystis wall greater partial excision adopted in 11 cases, partial resection in 8, then all patients were treated by spray painting fibrinogen gel.</p><p><b>RESULTS</b>Nineteen patients were followed-up for 13 to 30 months (mean 21.3 months). The clinical symptom disappeared completely in 18 patients, and only one patient urinated incapably, but after 2 weeks returned to normal. No one found recurrence by MRI after 12 months.</p><p><b>CONCLUSION</b>This method of fibrinogen gel for treating sacral canal arachnoid cyst has advantages of easy performing, safety, achieve good results, less neck symptoms and early commencing of mobilization.</p>
