RESUMO
BACKGROUND: We hypothesized that minimally invasive surgery was superior to conventional surgery for total hip arthroplasty procedure. PURPOSE: To compare the results of total hip replacement (THR) made by minimally invasive lateral approach with the results of THR made by conventional lateral approach. MATERIALS AND METHODS: Prospective, randomized trial. Fifty patients were selected and then divided into two groups based on utilized approach. DATA COLLECTED: Perioperative bleeding, postoperative pain, time of recovery, components orientation, complications and functional results. Five-year follow-up. RESULTS: No differences were found in blood loss, postoperative pain, surgical time, components orientation, rate of complications or functional result. Minimally invasive lateral approach produced faster recovery with less hospital stay and earlier walking start. CONCLUSION: Our results suggested that minimally invasive lateral approach has not provided significant benefits over conventional lateral approach for the implantation of a total hip arthroplasty.

AIM: Our objective was to compare the results of PCCP (Percutaneous Compression Plate) device and Gamma 3 nail for the treatment of stable trochanteric hip fractures and to demonstrate that PCCP device is a minimally invasive system. METHOD: Prospective, randomized trial. Eighty patients aged 60 and over with stable trochanteric fracture were selected and then randomized using a table of randomized numbers. Length of time of operative procedure, hemoglobin levels at 6 and 48 h after surgery, packed cells units administered, and hospital stay were recorded. In addition, the postoperative complications in the first year after the surgery was collected. RESULTS: No differences were found in hospital stay, surgical time, blood loss, functional outcome at 1-year follow-up, neck-shaft angle, fracture collapse, and mortality. CONCLUSIONS: PCCP and Gamma 3 have not presented significant differences in any measured parameter for treatment of stable trochanteric fractures. Therefore, the PCCP system is shown to be as minimally invasive as the Gamma 3.
