Table 4.
Summary of low, normal, and high offset classifications in select studies.
| Study | Decreased | Restored | Increased |
|---|---|---|---|
| Cassidy et al.,28 2012 | femoral offset >5 mm less than that of contralateral hip | femoral offset ± 5 compared to contralateral hip | femoral offset >5 mm greater than that of contralateral hip |
| Liebs et al.,14 2014 | actual offset >5 mm less than height adjusted offseta | actual offset within 5 mm of height adjusted offseta | actual offset > 5 mm greater than height adjusted offseta |
| Mahmood et al.,25 2016b | Postoperative offset > 5 mm less than that of contralateral hip | Postoperative offset within 5 mm of that of Contralateral Hip | Postoperative offset >5 mm greater than that of contralateral hip |
| Sariali et al.,26 2014 | minimum decrease of 15% in femoral offset postoperatively | femoral offset within 15% of preoperative offset | minimum increase of 15% in femoral offset postoperatively |
Height adjusted offset = 6.96 + 0.28 × height.
Used global offset = femoral offset + cup offset.
