Comparative Study
Metal ion levels and revision rates in metal-on-metal hip resurfacing arthroplasty: a comparative study.
Metal-on-metal (MoM) bearings in hip surgery are related to increased blood levels of metal ions. The nature of the relationship between ion levels and failure is still not fully understood. This study compares three cohorts of patients, 120 patients in each cohort, treated with a hip resurfacing arthroplasty, grouped by brand and diameter of femoral component on average four years postoperatively: Birmingham Hip Resurfacing ≥50 mm, Durom resurfacing ≥50 mm and Durom resurfacing <50 mm. ⋯ When similar ion levels were reported for BHR and small Durom the latter had significantly higher revision rates. This suggests ion levels do not absolutely predict the rate of HRA failure. Since MoM generation of metal ions is not the sole reason of failure, regular clinical and radiographic follow-up should also be in place for patients with these joints.

Comparative Study
Traumax screw plate vs. Gamma nail. Blood loss in pertrochanteric fractures treated by minimally invasive osteosynthesis.
This study is aimed to determine whether the Traumax dynamic hip screw reduces perioperative blood loss and transfusion rate compared to the Gamma nail in the treatment of pertrochanteric fractures. ⋯ Screw plate Traumax significantly reduces perioperative bleeding after pertrochanteric fractures. It avoids fracture gaps that tend to maintain bleeding. Given the morbidity and complications related to acute anaemia and blood transfusion, the surgical management of these elderly patients is aided by this choice of fixation.
