# Gait Training with a Dislocated Hip Spacer: A Case Study and Literature Review

## TL;DR

A patient with a dislocated hip spacer successfully underwent gait training and regained limited walking ability before eventual reimplantation.

## Contribution

This case study presents a successful rehabilitation approach for a patient with a dislocated hip spacer, offering insights into conservative management.

## Key findings

- The patient achieved standing with partial weight bearing after two weeks of inpatient rehabilitation.
- Three months later, the patient could walk short distances using a walker with assistance.
- The patient eventually underwent successful reimplantation of the definitive prosthesis after one year.

## Abstract

Background/Objectives: Spacer dislocation is among the most frequent mechanical complications after revision total hip arthroplasty for periprosthetic hip infection. Spacer dislocations may be managed conservatively, but there are no guidelines on the rehabilitation of these patients, and the restriction of weight bearing is still under debate. Methods: We first report the case of a patient with hip spacer cranial dislocation, judged unfit to be surgically treated once more for a medium period, who started a rehabilitation program with partial weight bearing. Results: After two weeks of inpatient rehabilitation, the patient started to maintain the standing position with partial weight bearing on the affected side. Following hospital discharge we continued rehabilitation in the outpatient clinic. Despite the finding of the denervation of the ipsilateral quadriceps, three months after admission, she was able to walk for short distances using a walker, initially with the help of a therapist and then with supervision. About one year later, she was able to undergo the reimplantation of the definitive prosthesis. Conclusions: Despite the spacer dislocation, walking short distances is a feasible goal, even with assistance, wearing a brace and using a walker. Future research is needed to confirm and expand upon this observation and to understand the mechanisms underlying the development of neurological complications to implement effective prevention strategies.
