Abstract
The purpose of this study was to evaluate early results of a new as yet not described minimal invasive posterior gluteus maximus splitting approach for total hip arthroplasty (THA) and also metal on metal hip resurfacing.
A new minimal invasive gluteus maximus splitting posterior approach is described backed up with intra-operative videos. This single incision approach allowed THA to be carried out through an incision ranging from 5.5 cm. to 9 cm. and metal on metal (MOM) resurfacing through an incision ranging from 7.5 cm. to 10 cm. Intra-operative fluoroscopy is not needed. The patients were not selected according to body mass index (BMI). All patients are suitable for this approach except for severely obese patients. 30 patients underwent THA (both cemented and uncemented) and 20 underwent MOM resurfacing. Early results at average 6 months indicate low post-operative pain scores, low blood loss (less than 5% needing transfusion), early mobilisation and discharge from hospital. Patients also returned to normal activities early with excellent cosmetic results and high patient satisfaction scores. There were no complications.
THA and MOM hip resurfacing can safely be done through a minimally invasive gluteus maximus splitting approach with excellent early results without any complication
