An interventional study of Direct Anterior Approach and Mini-Posterior Approach in Total Hip Replacement, sponsored by Mayo Clinic. Completed at 1 site in United States. Open to participants aged 20 Years to 100 Years. Per ClinicalTrials.gov, last updated 2018-12-05.
Sponsored by Mayo Clinic · Not applicable, Interventional, and Treatment
The primary aim of the study is to compare the results of an established, successful procedure, which is total hip arthroplasty through a mini-posterior approach to a less studied - increasingly popular procedure, which is total hip replacement through the direct anterior approach utilizing the orthopedic table.
Mayo Clinic is the lead sponsor of 3,218 studies on the registry; 670 are open to participants now.
Of its 445 completed or terminated interventional studies of FDA-regulated products, 313 (70%) have results posted.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria
An oblique incision is made over the anterior margin of the tensor muscle. The fascia of the tensor muscle is identified and incised. The muscle is swept digitally laterally and a retractor is placed over the superior aspect of the femoral neck. The hip capsule is then incised and retracted.
Procedure: Direct Anterior Approach
The surgical approach involved a 7 to 9.5 cm incision along the posterior aspect of the femur starting at the tip of the greater trochanter and proceeding distally. The fascia of the gluteus maximus was split, and blunt dissection revealed the underlying abductor and external rotator musculature. The external rotators an the hip capsule were incised and preserved as one layer, with an attempt being made to preserve the insertion of the quadratus femoris on the femur. The hip was dislocated posteriorly and the femoral neck was cut in accordance with the preoperative plan.
Procedure: Mini-Posterior Approach
Activity monitors will be worn
3 monitoring sensors will be worn by the subject.
Time frame: Baseline to 1 year
