Total Hip Arthroplasty in Patients With Postpolio Residual Paralysis: A Systematic Review.

BACKGROUND: Patients with postpolio residual paralysis can develop disabling hip arthritis in paralytic as well as a nonparalytic limb, warranting total hip arthroplasty (THA). Limited literature is available on the results of THA among these patients in the form of small series or case reports. We have undertaken a systematic review to evaluate the clinical outcome of THA in patients with poliomyelitis with hip pathologies. METHODS: A systematic search of electronic databases of PubMed, Scopus, and Web of Science pertaining to English literature was undertaken from 1945 to August 2020 to assess the results of THA in patients with poliomyelitis. Information was gathered about demographics, indication, clinical course, complications, functional outcome, survival, and need for any revision surgery in these patients. RESULTS: The literature search revealed 81 articles. Finally, after deduplication and manual selection, 16 relevant articles (128 hips) were included for evaluation. There is a paucity of literature evaluating THA in patients with poliomyelitis over the last 2 decades. The principal reason for arthroplasty was osteoarthritis of the hip in the ipsilateral (paralyzed) limb. A combination of cemented, uncemented, and hybrid implant fixation system was found to be used by surgeons. Addressing instability and perioperative management of limb length discrepancy were found to be challenging propositions. CONCLUSION: THA remains an effective intervention to relieve pain and improve quality of life in patients of poliomyelitis afflicted with either primary or secondary arthritis of the hip. The use of uncemented nonconstrained hip implant designs appears to demonstrate better results than constrained implants.
