Abstract:
OBJECTIVE:To explore the application effect of self-developed anatomical main nail insertion guide in proximal femoral nail antirotation (PFNA) internal fixation for the treatment of intertrochanteric fractures (IFF) in elderly patients.
METHODS:A retrospective analysis was performed on 62 patients with AO31-A2 intertrochanteric fractures who underwent PFNA surgery and met the inclusion criteria from January 2022 to December 2024. They were divided into the conventional PFNA insertion group (conventional operation group) and the anatomical main nail insertion guide-assisted PFNA insertion group(guide group). The conventional operation group (PFNA) included 31 patients, 14 males and 17 females, the age ranged from 64 to 90 with an average of (75.2±11.6) years old;the guide group (PFNA) included 31 patients, 10 males and 21 females, the age ranged fron 67 to 97 with an average of (78.6±13.4) years old. The incision length of the main nail entry, the number of fluoroscopies from satisfactory reduction to before main nail insertion, operation time, intraoperative blood loss, 3-day postoperative VAS score, postoperative hip function Harris score, complications, etc. were observed and compared between the two groups.
RESULTS:All patients were followed up for a period ranging from 4 to 12 months, with an average follow-up duration of (6.8±1.6) months. Compared with the guide group, the conventional operation group showed significant differences in the following parameters:the entrance length of the main screw was (6.74±3.77) cm vs. (5.13±1.31) cm, the number of fluoroscopies before the insertion of the main screw was (10.32±3.08) times vs. (7.71±2.41) times, the operation time was (150.45±53.47) minutes vs. (127.48±30.37) minutes, and the intraoperative blood loss was (196.77±121.06) ml vs. (140.97±86.00) ml, with P<0.05 indicating statistical significance.There was no statistically significant difference in 3-day postoperative VAS between the two groups (P>0.05). There was a statistically significant difference in the Harris scores between the conventional operation group and the guided operation group one month post-surgery (60.61±6.60) vs. (65.48±5.19) points (P<0.05). and there was no statistically significant difference in hip Harris scores between the two groups at 3 months after operation (P>0.05). During the 3-month follow-up after operation, neither group had incision infection, screw loosening, cutting, pressure sores, deep vein thrombosis, etc., and there was no statistically significant difference in the complication rate between the two groups.
CONCLUSION:It is quickly and accurately to implant PFNA assisted by the anatomical major nail implant guide in treatment of osteoporotic intertrochanteric fracture in the elderly.Compared with the traditional operation, it can shorten the operation time and reduce the surgical and X-ray trauma, and beneficial to the rapid rehabilitation of patients.
