Table 5 Comparison of perioperative outcomes and laboratory changes between subtrochanteric osteotomy (SO) and low femoral neck osteotomy (LRNO) groups.
| Parameter | SO (n=36) | LRNO (n=37) | P value |
|---|---|---|---|
| Operation time (min) | 165.00 (135.00–196.25) | 115.00 (100.00–150.00) | 0.000 |
| Blood loss (mL) | 700.00 (500.00–900.00) | 350.00 (300.00–600.00) | 0.002 |
| Blood transfusion volume (mL) | 250.00 (0.00–400.00) | 0.00 (0.00–0.00) | 0.000 |
| Blood plasma transfusion (mL) | 0.00 (0.00–200.00) | 0.00 (0.00–0.00) | 0.003 |
| Incision length (cm) | 23.00 (21.00–24.25) | 14.00 (12.00–16.00) | 0.000 |
| Δ Albumin (g/L) | 10.72 (7.58–14.42) | 7.32 (3.87–10.30) | 0.000 |
| Δ WBC (×10/L) | 4.11 (3.18–4.67) | 4.11 (2.85–5.74) | 0.736 |
| Δ Hb (g/L) | 28.35 (20.40–37.93) | 19.30 (10.50–25.20) | 0.000 |
| Δ ESR (mm/h) | 60.50 (45.75–73.00) | 46.00 (33.00–76.00) | 0.275 |
| Δ D-dimer (mg/L) | 1.43 (0.93–2.59) | 1.26 (0.46–2.30) | 0.480 |
| WBC – white blood cell count; Hb – hemoglobin; ESR – erythrocyte sedimentation rate; D-dimer – a fibrin degradation product. 1. Operation time, blood loss, blood transfusion volume, blood plasma transfusion, and incision length were directly compared between groups. 2. Laboratory parameters (albumin, WBC, Hb, ESR, D-dimer) were compared using absolute change values (|postoperative-preoperative|). Δ indicates the absolute change from preoperative to postoperative values (|postoperative minus preoperative|). 3. Due to non-normal distribution, data are presented as median (IQR), and between-group comparisons were performed using Wilcoxon rank-sum test. | |||
