Objective To compare the clinical efficacy of transforaminal lumbar interbody fusion under unilateral biportal endoscopy(UBE-TLIF)and traditional posterior lumbar interbody fusion(PLIF)in treating single-segment degenerative lumbar spondylolisthesis with lumbar spinal stenosis(DLS-LSS).Methods The clinical data of 85 patients diagnosed with DLS-LSS who underwent surgery between Jan.2020 and Jan.2022 in our hospital were retrospectively analyzed.Patients were assigned to UBE-TLIF group(46 cases)and PLIF group(39 cases)based on the surgical procedure.The general characteristics,perioperative data,radiological parameters,and clinical efficacy indicators were analyzed.Results There were no significant differences in baseline characteristics,preoperative radiological parameters,pain visual analogue scale(VAS)score,or Oswestry disability index(ODI)score between the 2 groups(all P＞0.05).Compared with the PLIF group,the UBE-TLIF group had significantly longer operation time([156.42+26.65]min vs[141.36+21.46]min,P=0.006),significantly less operation blood loss([170.15+10.87]mL vs[203.15+15.67]mL,P＜0.001),and significantly shorter hospital stay([6.73+2.42]d vs[9.61+2.56]d,P＜0.001).The UBE-TLIF group had significantly smaller lumbar lordosis and segmental angle 3 months postoperatively([42.52±8.57]° vs[46.61+7.31]°,[10.93+2.59]° vs[12.16+3.05]°)and at final follow-up([41.35+7.46]° vs[44.62+6.42]°,[10.65+2.43]° vs[11.87+2.53]°)compared with the PLIF group(all P＜0.05).The fusion rate was significantly lower in the UBE-TLIF group compared with the PLIF group 3 months after operation(34.78％[16/46]vs 58.97％[23/39],P＜0.05),with no significant difference at final follow-up(93.48％[43/46]vs 94.87％[37/39],P＞0.05).The VAS score and ODI score 3 months after operation were significantly lower in the UBE-TLIF group compared with the PLIF group(2.43+0.92 vs 3.12±1.03,26.81+9.14 vs 33.35+8.76,both P＜0.01),with no significant differences at final follow-up(both P＞0.05).Conclusion As a minimally invasive surgical technique,UBE-TLIF has the advantages of minimal trauma,fast recovery,mild postoperative pain,and a reliable fusion rate.It is an effective treatment for DLS-LSS and deserves to be promoted.

Objective To observe the efficacy of traditional Chinese medicine and intertrochanteric combination thera-py fractures. Methods From January 2009 to January 2011 in our hospital,100 cases of intertrochanteric fracture pa-tients were randomly divided into observation group and control group,50 cases in each group,the two groups were performed within PFNA fixed,observation group were simultaneously combined traditional Chinese medicine treatment,after treatment,the fracture healing time,Harris hip score,incidence of complications of two groups were compared. Results After treatment,the excellent rate of observation group was 86%,was significantly higher than the control group of 72%,the difference was statistically significant (χ2=4.127,P<0.05).The fracture healing time of observation group was significantly shorter than the control group,but Harris hip score of t observation group patients was significantly higher than the control group,the difference was statistically significant (P<0.05).The complication rate of observation group was 10%,was significantly lower than the control group of 26%,the difference was statistically significant (χ2=11.348,P<0.05). Conclusion Integrative treatment of intertrochanteric fractures with good effect,can promote healing,significantly improve hip function in patients,reduce the incidence of complications,should be promoted and applied.
