[Dislocation-disassembly of bipolar hip arthroplasty--case report]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Bipolar hip arthroplasty is a common procedure for treating femoral neck fractures.
• Dislocation of bipolar hip arthroplasty is an infrequent but serious complication.

Observation:

• A patient with neurological deficits experienced bipolar hip arthroplasty dislocation after a posterolateral approach for femoral neck fracture.
• During closed reduction, the bipolar prosthesis disassembled.

Findings:

• Open reduction and bipolar head exchange were required to address the dislocation and disassembly.
• Neurological deficits may be a contributing factor to hip arthroplasty complications.

Implications:

• Performing closed reduction under anesthesia with complete muscle relaxation is crucial to prevent bipolar prosthesis disassembly.
• Careful patient selection and surgical approach are important in minimizing dislocation risks in bipolar hip arthroplasty.
