There are few reports showing the results of minimally invasive total hip arthroplasty (MIS-THA) for osteoarthritis in patients with Parkinsonism. Here, we report two cases of osteoarthritis treated by MIS-THA using the anterolateral-supine approach (ALSA) in patients with Parkinsonism. The first case involved a 75-year-old woman with Parkinson syndrome who presented to our hospital with severe right hip joint pain in 2010. The patient had osteoarthritis of the hip and underwent MIS-THA utilizing ALSA in January, 2011. The surgical time was 88 min and the estimated blood loss during surgery was 495 ml. At present, 8 months postoperatively, the patient is pain free and is able to walk with a walking frame. The second case involved a 71-year-old woman with Parkinson disease who also presented to our hospital with severe right hip joint pain in 2010. The patient had osteoarthritis of the hip and underwent MIS-THA utilizing ALSA in February, 2011. The surgical time was 100 min and the estimated blood loss during surgery was 314 ml. At present, 8 months postoperatively, she is also pain free and is able to walk with a walking frame. One of the complications we should try to prevent following THA for osteoarthritis in patients with Parkinsonism is postoperative dislocation. Therefore we performed MIS-THA utilizing ALSA in these two cases, leading to good postoperative functional outcomes. It is our belief that muscle-preserving MIS-THA using ALSA is a promising strategy for osteoarthritic hips in patients with Parkinsonism.
