Abstract

Objectives: The magnitude of femoral head collapse (MFHC) is one of the criteria for staging osteonecrosis of the femoral head (ONFH). The present study aimed to clarify the relationship between MFHC and hip pain or functional quality of life (QOL) scores in patients with ONFH.

Methods: Seventy patients with ONFH who had femoral head collapse without osteoarthritic changes were divided into four groups based on MFHC by 1 mm. Pain was assessed using the visual analogue scale (VAS). QOL was evaluated using patient-reported outcome measures such as the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ), Oxford Hip Score (OHS), and Short Form-12 Health Survey, version 2 (SF-12v2). We also explored the relationship between MFHC and QOL.

Results: Pain score and satisfaction score in the VAS, JHEQ pain subscale, JHEQ movement subscale, and JHEQ total score were significantly associated with MFHC, and no significant differences were found between groups in any subscale or total score for OHS and SF-12v2.

Conclusion: In patients with ONFH, differences in MFHC by 1 mm were associated with deterioration of some pain VAS and QOL outcomes.
