Pediatric diaphyseal forearm fractures, often caused by sports or leisure activities, require treatment based on fracture stability. While stable fractures can be managed conservatively, unstable fractures typically require surgery, with elastic stable intramedullary (IM) nailing (ESIN) being the gold standard. Bioabsorbable IM nails (BINs) offer an alternative by eliminating the need for implant removal surgery. Methods: Between May 2023 and January 2025, we consecutively managed 161 children with poly- L-lactic-co-glycolic acid (PLGA) BINs in two healthcare centers for diaphyseal forearm fracture and evaluated every reported difficulty and complication of resorbable IM nails. Results: Seven unique peri- or postoperative events occurred during the study period. Even with a high success rate, some complications occurred during the study period. Difficulties and complications were mainly dependent on the surgical technique. Iatrogenic complications such as bone cortex perforation and implant end split were evaluated, along with anatomical variations like focal and general medullary cavity stenosis narrowings that implant insertion. Secondary malalignment, one early (2 months) refracture, and one recurrent fracture (2 years) were also noted. Conclusions: Although BINs reduce the need for a second surgery, careful planning, technique, and follow-up are crucial for optimal outcomes. Further research is needed to assess long-term results and complications.
