Table 4 Comparison of complications between subtrochanteric osteotomy (SO) and low femoral neck osteotomy (LRNO) groups.
| Complication | SO (n=36) | LRNO (n=37) | P value |
|---|---|---|---|
| LLD (cm) | 1.51±0.59 | 0.60 (0.40–0.90) | 0.000 |
| DVT | 2 (5.56%) | 2 (5.41%) | 1.000 |
| Dislocation | 1 (2.78%) | 1 (2.70%) | 1.000 |
| Nerve injury | 0 (0.00%) | 3 (8.11%) | 0.240 |
| Aseptic loosening | 1 (2.78%) | 0 (0.00%) | 0.493 |
| Nonunion | 2 (5.56%) | 0 (0.00%) | 0.240 |
| PJI | 0 (0.00%) | 1 (2.70%) | 1.000 |
| Periprosthetic fracture | 0 (0.00%) | 3 (8.11%) | 0.240 |
| DVT – deep vein thrombosis; LLD – leg length discrepancy; PJI – periprosthetic joint infection. Statistical tests: Mann-Whitney U test for LLD; Fisher exact test for categorical variables. Values are presented as mean±SD or median (IQR) for LLD, and as n (%) for categorical variables. | |||
