摘要Introduction: Total hip arthroplasty is a commonly performed procedure worldwide. Instability and dislocation continue to be a significant cause of revision, with 22.5% reported by Bozlc in 2009. Neuromuscular disorder is a known risk factor for dislocation. Dual mobility articulation has been designed aiming at minimizing the risk of dislocation. This study aimed to review the dislocation rate in patients with underlying neuromuscular disorders in whom total hip arthroplasty with dual mobility articulation has been implanted.

Methodology: Patients with underlying neuromuscular disorder underwent total hip arthroplasty with dual mobility articulation implants were reviewed. Clinical results, dislocation rate and other complications were recorded.

Results and Analysis: From 2016 to 2018, four patients were identified. Underlying neuromuscular disorders included Parkinson’s disease with history of stroke, poliomyelitis, epilepsy and spinal cord injury. Three patients underwent total hip arthroplasties for hip fracture or its complications, while one patient was indicated due to hip dysplasia. In the latest review, all patients had improvement in pain and no dislocation.

Discussion and Conclusion: Compared to traditional total hip arthroplasty implants, dual mobility articulation implants achieved a lower dislocation rate. This is advantageous to high risk patient groups such as those with underlying neuromuscular disorders. For further insight of the use of dual mobility articulation implants in neuromuscular disorder patients, recruitment of more cases and longer duration of follow up is needed.
