Comparison of postoperative outcomes between patients over 100 years of age and those in their 90s.
| Postoperative outcome | Patients aged in their 90s | Patients aged over 100 years | P-value |
|---|---|---|---|
| Waiting time (hours) | 91.5 ± 65.3 | 35.2 ± 22.7 | 0.001* |
| Surgical procedure (ORIF/BHA) | 99/38 | 9/6 | 0.320 |
| Operative time (minutes) | 55.4 ± 19.5 | 54.1 ± 18.7 | 0.816 |
| Blood loss (ml) | 121.5 ± 117.3 | 119.4 ± 97.8 | 0.896 |
| Blood transfusion volume (ml) | 460.7 ± 312.2 | 480.0 ± 374.0 | 0.761 |
| Perioperative complications (%) | 19.0 (26/137) | 13.3 (2/15) | 0.592 |
| Hospital stay (days) | 42.6 ± 20.4 | 38.3 ± 21.8 | 0.449 |
| Returned to original living environment (%) | 56.2 (77/137) | 80 (12/15) | 0.076 |
| Regained walking ability (%) | 51.4 (55/107) | 60 (6/10) | 0.603 |
| One-year survival rate (%) | 89.8 (123/137) | 93.3 (14/15) | 0.661 |
Waiting time, waiting time from visit to surgery; ORIF, open reduction and internal fixation; BHA, bipolar hip arthroplasty; Returned to original living environment, the percentage of patients who were able to return to their previous facility or home environment; Regained walking ability, the proportion of patients who regained the ability to walk independently or with minimal assistance. Data of patients who did not have the ability to walk before surgery were excluded from the calculation.
