# Clinical Algorithm for the Management of Ipsilateral Proximal and Shaft Femur Fractures Using Single or Dual Implants

## TL;DR

This study compares single and dual implant treatments for complex femur fractures and proposes a clinical algorithm to guide implant selection.

## Contribution

A new clinical algorithm is proposed for managing ipsilateral proximal and shaft femur fractures using single or dual implants.

## Key findings

- Both single and dual implant methods showed similar clinical outcomes with no non-union or avascular necrosis.
- The clinical algorithm helps guide implant selection based on injury patterns.

## Abstract

Purpose of the study

The current study had two goals: first, it compared the radiological and functional results of the ipsilateral shaft and proximal femur fractures treated by using two different methods, i.e., single implant vs dual implants. The second goal was to devise a clinical algorithm for guiding and managing such fractures.

Methods

This study was conducted in a level 1 trauma center and included 34 patients with concomitant ipsilateral fractures of the proximal femur and shaft of the femur. The patients were divided into two groups as per our clinical algorithm. Group I, comprising of 16 patients, were treated with a single implant like the proximal femoral nail (PFN) or proximal femoral nail antirotation (PFNA2). Group II of dual implants, comprising of 18 patients, were treated with two types of implants separately for proximal and shaft fracture.

Results

All patients were followed at monthly intervals up to six months, then at three monthly intervals up to one year, with a minimal follow-up of one year of every patient. On clinical evaluation by Friedman-Wyman criteria, in group I, seven patients had a fair outcome, eight patients had a good outcome, and one patient had a poor outcome, while in group II, eight patients had a fair outcome, nine patients had a good outcome, and one patient had a poor outcome. No patient developed non-union or avascular necrosis of the femoral head in any of the groups.

Conclusion

For concurrent ipsilateral diaphyseal and proximal femur fractures, both dual and single implants are equally effective alternatives if properly applied as per our clinical algorithm. Implant selection primarily depends on the pattern of injury, and our clinical algorithm can be a suitable guide for guiding the selection of implants.
