Abstract:
OBJECTIVE:To compare the effects of bilateral vertebral puncture guided by an angle-adjustable linear laser auxiliary device versus free-hand bilateral vertebral puncture.
METHODS:A retrospective analysis was conducted on the clinical data of 47 patients who underwent thoracolumbar percutaneous kyphoplasty(PKP) from July 2022 to July 2023. All patients received bilateral percutaneous kyphoplasty, among whom 27 cases underwent conventional free-hand puncture (conventional puncture group) and 20 cases underwent puncture guided by a laser auxiliary device (auxiliary puncture group). In the conventional puncture group, there were 11 males and 16 females, with an average age of (69.6±5.1) years and a disease duration of (6.5±3.8) days;the fractured vertebrae were T11-T12 in 13 cases and L1-L2 in 14 cases. In the auxiliary puncture group, there were 7 males and 13 females, with an average age of (70.8±5.6) years and a disease duration of (6.4±3.8) days;the fractured vertebrae were T11-T12 in 7 cases and L1-L2 in 13 cases. The operation time, total blood loss, intraoperative fluoroscopy times, fluoroscopy duration, radiation dose, puncture success rate, and surgical complications were compared between the two groups. The visual analogue scale (VAS) was used to evaluate low back pain before surgery, 2 days after surgery, and 1 year after surgery.
RESULTS:All patients achieved successful puncture, with good postoperative wound healing and no complications. The operation time of the auxiliary puncture group was (12.1±2.6) minutes, which was shorter than that of the conventional puncture group (14.1±2.8) minutes. The total blood loss of the auxiliary puncture group was (228.5±35.8) ml, less than that of the conventional puncture group (257.0±48.3) ml. The fluoroscopy times, fluoroscopy duration, and radiation dose of the auxiliary puncture group were (5.4±1.3) times, (15.9±3.3) seconds, and (159.4±37.4) μSv, respectively, all lower than those of the conventional puncture group (6.4±1.6) times, (18.8±4.6) seconds, (192.2±48.5) μSv, with statistically significant differences(P<0.05). There were no statistically significant differences in low back VAS scores between the two groups before surgery, 2 days after surgery, or 1 year after surgery(P>0.05).
CONCLUSION:Both laser auxiliary device-guided vertebral puncture and free-hand vertebral puncture have high success rates and similar postoperative curative effects. However, the laser auxiliary device-guided puncture has shorter operation time, less blood loss, and lower radiation hazard.
