INTRODUCTION: Surgical management of younger patients requiring primary total hip arthroplasty is challenging due to increased activity levels, physical demands, and the need for longevity of implanted components. There is debate regarding the most suitable component type, and the optimal fixation, should a stemmed component be utilised. MATERIALS AND METHODS: We retrospectively reviewed a sequential group of patients, aged 55 years or younger at the time of surgery, who underwent uncemented primary total hip arthroplasty, and are currently at a minimum of 5 years post operation. Eighty-eight primary uncemented total hip replacements were performed between January 2004 and December 2006. The patient ages ranged from 18 to 55 years with a mean of 43.1 years at time of operation. At last review, eight patients (ten hips) had demised of unrelated causes and 16 patients (20 hips) were lost before completing 5 years of follow-up. RESULTS: Complications included one peri-operative mortality, ten intra-operative femoral calcar fractures, two revisions for sepsis, one dislocation and one deep vein thrombosis. All stems achieved bony fixation as per Engh's criteria. At a minimum of 5 years post operation, there were no revisions for aseptic loosening. CONCLUSION: We present our radiological results, complications, and survivorship of uncemented primary total hip replacements in patients 55 years or younger.
