J Am Acad Orthop Surg April 2012 Anand Srinivasan Abstract Modular femoral components have been developed to aid in recreating native femoral version, limb length, and offset in total hip arthroplasty. Use of modular implants results in cost savings, as well. Inventory can be reduced while allowing intraoperative flexibility and …

Megan A. Swanson, JAAOS December 2011;19 (12) Abstract Altered biomechanics secondary to hip ankylosis often result in degeneration of the lumbar spine, ipsilateral knee, and contralateral hip and knee. Symptoms in these joints may be reduced with conversion total hip arthroplasty (THA) of the ankylosed hip. THA in the ankylosed …

Walter, MBBS, FRACS, PhD, Eric Yeung, FRCS (Tr+Orth) and Christina Esposito, BSc The incidence of squeaking in hip replacement varies for ceramic-on-ceramic and metal-on-metal bearings, and the implications are not fully understood. Contributing factors may include component …

J Am Acad Orthop Surg, Vol 18, No 6, June 2010 Marc R. Safran, MD The past decade has seen unprecedented growth in the number of hip arthroscopies. Acetabular labral tears are the leading indication for arthroscopy of this joint. However, labral anatomy and function, as well as the effects …

NULL J Am Acad Orthop Surg, Vol 18, No 5 Joseph T. Moskal, MD and Susan G. Capps, PhD Improper acetabular component orientation negatively affects the outcome of total hip arthroplasty through increasing dislocation rates, component impingement, bearing surface wear, and the number of revision surgeries. Leg length, hip biomechanics, …

J Am Acad Orthop Surg, Vol 18, No 4, April 2010 David M. Foulk, MD and Brian H. Mullis, MD A simple hip dislocation is one without fracture of the proximal femur or acetabulum. Complex fracture-dislocations involve the acetabulum, femoral head, or femoral neck. The incidence of posttraumatic arthritis is …
