A case of neuropathic arthropathy of the elbow with early loosening after total elbow arthroplasty.

We reported the case of a 65-year-old woman who presented with neuropathic arthropathy of the elbow and had undergone cervical spinal cord tumour resection at 32 years of age. Open synovectomy with free-body resection was performed; however, the instability of the elbow joint rapidly progressed. Therefore, we performed total elbow arthroplasty using a linked-type prosthesis. However, the humeral stem severely loosened 1 year after arthroplasty. Further, a peri-prosthetic humeral fracture developed due to a minor trauma. Revision total elbow arthroplasty using a long-stem prosthesis was performed 4 years after the primary total elbow arthroplasty. Radiographs taken 2 years after the revision surgery showed no evidence of implant loosening. In this case, early post-operative loosening occurred despite the use of a linked-type prosthesis and an appropriate cementing technique, suggesting that normal implants may not provide sufficient fixation for neuropathic arthropathy of the elbow. Since surgery for neuropathic arthropathy generally has a poor prognosis, surgical interventions including total elbow arthroplasty should be carefully considered.
