# Sagittal Band Disruption Following Percutaneous Retrograde Intramedullary Screw Fixation of a Metacarpal Shaft Fracture: A Case Report

## TL;DR

A man developed a rare complication called sagittal band disruption after a surgical procedure to fix a metacarpal fracture.

## Contribution

This case report highlights a rare complication of percutaneous retrograde intramedullary screw fixation.

## Key findings

- Sagittal band disruption occurred following the surgical procedure.
- The patient experienced ulnar deviation as a result of the complication.
- The report emphasizes the need for awareness and reconsideration of fixation techniques.

## Abstract

Metacarpal fractures may be managed operatively or non-operatively, with malrotation being an indication for operative management. High rates of stiffness have been reported following operative management of metacarpal fractures, and intramedullary screw fixation is a widely accepted treatment that allows early range of motion to help prevent stiffness. While there are some known complications of this treatment modality, there are limited reports of sagittal band disruption. We report the case of a man who presented with sagittal band disruption and ulnar deviation following percutaneous retrograde intramedullary screw fixation of a metacarpal shaft fracture. This report includes details of the patient’s injury, treatment, complication, and follow-up, and urges the awareness of the complication and a reconsideration in the fixation approach and technique.
