Background: Minimally invasive surgery (MIS) has had a progressive development in recent years, due to its advantages in terms of: reducing the rates of complications, infection, surgical time and bleeding. Total hip arthroplasty (THA) has not been exempt from this current. Since of the first descriptions in 90´, several different techniques has been described to achieve smaller incisions and better results in primary THA, however, there is not enough statistical evidence to widely recommend MIS-THA, defined as an incision < 8 cm.
Materials and Methods: We retrospective reviewed a cohort of 173 THA, 55 men and 118 women, between January 2016 and October 2019, in an advanced trauma hospital, all performed by the same surgeon. An independent team, blinded to the primary diagnosis, performed a standardized clinical and radiological evaluation at 2, 6 and 12 weeks.
Results: The average length of the incision was 71 mm (48 - 84 mm). The average surgical time was 68 minutes (42 - 175). Hematocrit decreased by an average of 3.8% (2.2 - 8.1%). Average blood loss was 335 ml (120 - 950 ml). Preoperative Harris Hip Score was 67 (45 - 76) and postoperatively at 12 weeks of 92 (82 - 97). Three cases of perioperative complications where reported: 1 case of calcar fracture with extended approach (84 mm) and cerclage fixation, 1 case of prosthetic dislocation and 1 postoperative periprosthetic fracture Vancouver B2. No cases of neurovascular injury, infection or misalignment of components were reported.
Conclusion: These results with a locally developed technique, achieved satisfactory clinical and radiological outcomes, with minimum incisions up to 48 mm, with an average reduction of 50% to the standard approach (13 - 15 cm).
