ABSTRACT
OBJECTIVE:
To explore the effect of cephalomedullary nails for elderly intertrochanteric fractures proximal femoral nail antirotation (PFNA) versus zimmer natural nail (ZNN) to provide the data support for clinical perioperative management.METHODS:
A retrospective study was used to analyze the clinical data of elderly intertrochanteric fractures cases which were treated with PFNA or ZNN fixation from May 2016 to May 2017. In the study, 59 cases were followed up completely, in which 28 cases accepted PFNA, and the other 31 cases accepted ZNN. The operation time, amount of bleeding, fracture healing time, postoperative complication, postoperative radiographic measurement (tip apex distance, TAD) and the last follow-up of hip function score were analyzed.RESULTS:
The patients were followed up for 6 to 19 months, with an average (10.8±4.0) months. In PFNA group, the operation time was (62.7±14.2) min, the amount of bleeding was (56.8±20.6) mL, the fracture healing time was (4.6±0.8) months, the postoperative complication was 3.6%, the TAD was (17.7±5.5) mm, and the last follow-up hip function score was 91.8±3.6. In ZNN group, the operation time was (73.6±18.3) min, the amount of bleeding was (68.7±31.6) mL, the fracture healing time was (4.5±0.7) months, the postoperative complication was 3.2%, the TAD was (16.5±4.7) mm, and the last follow-up hip function score was 92.2±3.8. The two groups of comparative experiments were carried out, the operation time of the PFNA group was less than that of the ZNN group (P<0.05). There was no significant difference in the amount of bleeding, fracture healing time, postoperative complication, TAD, postoperative hip score between the two groups (P>0.05).CONCLUSION:
Although group ZNN had significant longer operation time than group PFNA, both implants were useful tools in the treatment of elderly intertrochanteric fractures. The operation of PFNA was simpler,while the design of the anterior bow of ZNN might be more suitable for the patients with a large femoral anterior bow.
