Total hip arthroplasty using the direct anterior approach and intraoperative neurophysiological monitoring for Crowe III hip dysplasia : surgical technique and case series.

We report a new technique to perform THA in high congenital dislocations. Between 2013 and 2015, 3 consecutive patients (4 hips) with severe hip pain and Crowe III hip dysplasia were treated. Surgeries were performed on a standard table using the DAA and intraoperative neurophysiological monitoring. At final follow-up (mean 24 months, range 15-43), all 3 patients reported excellent pain relief and significant improvement in activities of daily living. Radiographs showed the components to be solidly fixed in satisfactory position. Average postoperative leg lengthening was 24 mm (range 20-36). None of the patients experienced an acute or delayed neurologic deficit. Total hip arthroplasty for high congenital dislocations can be safely performed using the direct anterior approach and neuromonitoring. Significant lengthening could be obtained without neurological complications. PMID: 32490769 [PubMed - in process]
