Background
Elastic stable intramedullary nailing (ESIN) and plates are currently the main internal fixation for treating Pediatric Diaphyseal Femur Fractures (PDFF), and the optimal choice of internal fixation is controversial. The purpose of this meta-analysis is to compare the surgical outcomes and complications of the two fixation methods.
Materials and Methods
MEDLINE, Embase, and the Cochrane Library were systematically searched for studies published up to March, 2023, that compared ESIN and plate fixation techniques for treating PDFF. Pooled analysis identified differences in surgical outcomes between ESIN and plate, mainly regarding surgical outcomes and postoperative complications, such as time at surgery, fracture healing time, blood loss and related complications.
Results
We included 10 studies with 775 patients with PDFF in our review. Of these, 428 and 347 were treated with ESIN and Plate, respectively. In terms of postoperative complications, ESIN led to a shorter surgery time [MD = − 28.93, 95% CI (− 52.88 to − 4.98), P < 0.05], less blood loss [MD = − 66.94, 95% CI (− 87.79 to − 46.10), P < 0.001] and more fracture healing time [MD = 2.65, 95% CI (1.22–4.07), P < 0.001]. In terms of postoperative complications, ESIN led to fewer fections (RR = 0.77, 95% CI 0.37, 1.60, P = 0.48), fewer angulation deformities (RR = 0.80, 95% CI 0.35, 1.83, P = 0.60) and more prominent implants (RR = 3.36, 95% CI 1.88, 6.01, P < 0.001), more delayed unions (RR = 4.06, 95% CI 0.71, 23.06, P = 0.11).
Conclusions
ESIN and Plate have similar rates of complications besides a prominent implant rate, while ESIN has a shorter period of operation and less intraoperative bleeding. Although both options are suitable, the results of this study support the use of ESIN rather than plates in the treatment of PDFF in terms of complication rates. In clinical applications, surgeons should choose the appropriate treatment method according to the actual situation.
