Cementless femoral neck endoprosthesis SPIRON in men in aspects of clinical status and quality of life in an average 7-year follow-up

BMC Musculoskelet Disord. 2022 Aug 3;23(1):739. doi: 10.1186/s12891-022-05710-1.


BACKGROUND: We report the clinical evaluation, quality of life and pain assessment in patients who had a femoral neck SPIRON endoprosthesis.

METHODS: The study group consisted of 27 men in whom 35 femoral neck endoprosthesis were implanted (8 on the left side, 12 on the right side and 7 bilateral) due to idiopathic osteoarthritis of the hip (20 patients) or avascular femoral osteonecrosis (7 patients) in a mean 7-year follow-up.

RESULTS: The median pre-operative Harris Hip score (HHS) was 35.5 and post-operative 98.5 (p < 0.001). The median WOMAC HIP score was pre-operatively 57 and post-operatively 0 (p < 0.001). The median SF-12 score was pre-operatively 4 and post-operatively 33 (p < 0.001). The median pain assessment in VAS scale was 7 pre-operatively and 0 post-operatively (p < 0.001).

CONCLUSIONS: The results of all examined patients have changed significantly in every category showing that SPIRON endoprosthesis improved their quality of life and statistically reduced pain ailments. Moreover we have proved that higher BMI (> 30) is associated with worse operation outcomes.
