These studies did not show a satisfactory overall survival rate
Background and purpose The aim of short-stem total hip arthroplasty is to preserve proximal bone stock for future revisions , to improve biomechanical reconstruction , and to make minimally invasive approaches easier .
It is therefore being increasingly considered to be a sound alternative to conventional total hip arthroplasty , especially for young and active patients .
However , it is still unknown whether survival rates of short-stem  hips match current st and ards .
We made a systematic summary of reported overall survival after short-stem total hip arthroplasty .
Medium Term Follow up of the Biodynamic Neck Sparing Prosthesis
Hip resurfacing ( HR ) and neck sparing prostheses ( NSP ) have been advocated for the treatment of arthritis in younger patients . Some complications following HR have been documented in the recent literature , but NSP are not yet supported by clinical follow-up studies of sufficient duration . We present an assessment of the neck sparing “ Biodynamic ” prosthesis .  153 patients were evaluated in a longitudinal cohort prospect i ve study , with survival analysis , clinical score and radiographic assessment of stability and osteointegration at 41.8 months average follow up . Survival and clinical outcome were similar to most traditional prostheses in the literature . On radiographic analysis we recorded good neck preservation and osteointegration . Only two stem failures were recorded . Poor clinical outcome was related to misalignment of prostheses implanted during the ‘ learning curve ’ . The NSP system described may be a good alternative to HR for younger patients . The system is characterized by good survival and clinical and radiographic outcome combined with bone stock preservation
