# Intraoperative Abdominal Penetration of the Lag Screw: A Rare Complication During Proximal Femoral Nail Anti‐Rotation Surgery

## TL;DR

This paper reports a rare surgical complication where a lag screw used in PFNA surgery accidentally penetrates the abdomen.

## Contribution

The paper highlights a previously uncommonly reported intraoperative complication of PFNA surgery involving abdominal penetration by a lag screw.

## Key findings

- Intraoperative abdominal penetration by a lag screw is a rare but critical complication of PFNA surgery.
- Surgeons should be aware of this unique complication to prevent osteosynthesis failure.
- The case underscores the technical challenges associated with PFNA use.

## Abstract

Although the proximal femoral nail anti‐rotation (PFNA) is accompanied by several benefits, using the nail is technically challenging and may pose some errors, leading to osteosynthesis failure. Here, we report a critical presentation of an uncommon side effect of PFNA surgery. Intraoperative abdomen penetration via lag screw is a unique complication of PFNA surgery of which surgeons should be aware.
