INTRODUCTION: Minimally invasive approaches entail an increased risk of malpositioning and peri-operative complications. Most studies analyzed these data only on plain X-ray rather than computed tomodensitometry (CT) in assessing implant positioning.
HYPOTHESIS: A Röttinger minimally invasive anterolateral (MIS-AL) approach provides rapid complication-free functional recovery with reliable implant positioning on CT-scan.
PATIENTS AND METHOD: One hundred and three primary cemented total hip replacements (THR) performed by a single surgeon using a MIS-AL approach underwent clinical assessment at six weeks and three, six and 12 months on X-ray, including CT and postoperative myoglobinemia and creatine phosphokinase (CPK).
RESULTS: Pain, on a visual analog scale, was graded less than 1 at 36 hours; canes ceased to be used at a mean three weeks; and mean Postel-Merle-D'Aubigné score at six months was 17.36 (range, 13-18). There were ten approach-related complications (9.7%: one femoral perforation, two dislocations, two femoral neck fissures, two cases of meralgia paresthetica and three of tensor tendinitis). Mean CPK level was 390.9 ± 252μg/L (range, 88-1095μg/L) at 24 hr postoperatively and 319 ± 256μg/L (95-1028 μg/L) at 48 hr. Mean postoperative myoglobinemia was 299 ± 152.6μg/L (75-914μg/L). Mean acetabular inclination and anteversion on CT were respectively 44.7° ± 4.6° (34° - 56°) and 9.2°±9.2° (-17°-35°) and mean femoral anteversion 23.5° ± 9.4° (2°-53°).
DISCUSSION: Functional recovery was quick, but with an 8.7% complications rate (excluding four cases of spontaneously resolved tendon pain). CT showed reliable cup positioning, but a wide scatter in femoral anteversion. Elevated muscle enzyme levels possibly testified to approach-related tissue attrition. The MIS-AL approach involves a learning curve to avoid femoral perforation. It provided rapid functional recovery with reliable positioning, at least for the cup, and a low rate of associated complications.
LEVEL OF EVIDENCE: III, prospective continuous study.
