ABSTRACT
Objective:
To investigate the clinical efficacy of percutaneous kyphoplasty (PKP) through the transverse process-pedicle approach (TPPA) by comparing with PKP through the conventional transpedicle approach (CTA).Methods:
A retrospective study was conducted to analyze the data of 101 patients with single-segment osteoporotic vertebral compression fracture (OVCF) who had been treated at Department of Spine Surgery, The Fourth Hospital of Wuhan from August 2020 to August 2021. There were 31 males and 70 females, with an age of (70.3±7.6) years. Their T values of bone mineral density averaged (-3.0±0.3). They were divided into a TPPA group of 52 cases in which PKP was performed through the TPPA and a CTA group of 49 cases in which PKP was performed through the CTA. The clinical efficacy was evaluated by comparing the 2 groups in terms of operation time, frequency of intraoperative fluoroscopy, excellent to good rate of bone cement distribution, rate of bone cement leakage, refractures, and visual analogue scale (VAS), Oswestry disability index (ODI) and Beck index at preoperation, 24 hours, 3 months and 6 months postoperation.Results:
There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P>0.05). All the patients were followed up for (9.8±1.5) months. Operations were completed successfully in all patients with no complications like nerve injury or pedicle fracture. There were no significant differences in operation time, frequency of intraoperative fluoroscopy or rate of bone cement leakage between the 2 groups ( P>0.05). In the TPPA group, the excellent to good rate of bone cement distribution [92.3% (48/52)] was significantly higher than that in the CTA group [61.2% (30/49)], the VAS score [3.0 (2.0, 4.0)] and ODI (57.2±4.6) at 24 hours postoperation were significantly lower than those in the CTA group [4.0 (3.0, 4.0) and 59.2±5.3] ( P<0.05). There were no significant differences in VAS or ODI between the 2 groups at preoperation, 3 months or 6 months postoperation ( P>0.05). The VAS and ODI improved steadily within each group, showing significant differences between every 2 time points ( P<0.05). The Beck indexes [0.81 (0.69, 0.86) and 0.76 (0.67, 0.81)] at 24 hours and 6 months postoperation in the TPPA group were significantly higher than those in the CTA group [0.75 (0.71, 0.79) and 0.72 (0.68, 0.77)] ( P<0.05). The Beck indexes at 24 hours and 6 months postoperation improved significantly in all patients compared with the preoperative values ( P<0.05).Conclusions:
In the treatment of OVCF with PKP, the TPPA shows the same surgical safety as CTA does, but leads to better cement distribution, better pain relief at immediate postoperation and an advantage in restoring and maintaining the height of the injured vertebral body.
