A Review of Current Fixation Use and Registry Outcomes in Total Hip Arthroplasty: The Uncemented Paradox

Anders Troelsen MD, PhD, DMSc, Erik Malchau MD, Nanna Sillesen MD, Henrik Malchau MD, PhD

The majority (86%) of THAs performed in the United States are uncemented. This may increase the revision burden if uncemented fixation is associated with a higher risk of revision than other approaches.

Periprosthetic Femur Fractures Treated With Modular Fluted, Tapered Stems

Matthew P. Abdel MD, David G. Lewallen MD, Daniel J. Berry MD

Treatment of periprosthetic femur fractures is challenging, and high failure and complication rates have been reported in many series. The optimal techniques and implants for the management of Vancouver B2 and B3 fractures remain in debate.

Surgical Approaches for Cam Femoroacetabular Impingement: The Use of Multicriteria Decision Analysis

Claudio Diaz-Ledezma MD, Javad Parvizi MD

Currently, three surgical approaches are available for the treatment of cam femoroacetabular impingement (FAI), namely surgical hip dislocation (SHD), hip arthroscopy (HA), and the miniopen anterior approach of the hip (MO). Although previous systematic reviews have compared these different approaches, an overall assessment of their performance is not available.

Low Rate of Dislocation of Dual-mobility Cups in Primary Total Hip Arthroplasty

Antoine Combes MD, Henri Migaud MD, Julien Girard MD, PhD, Alain Duhamel PhD, Michel Henri Fessy MD, PhD

Dual-mobility (DM) cups were introduced to minimize the risk of THA dislocation. The overall rate of dislocation of DM cups (including both large and small articulations) is controversial and ranges from 0% to 5% in previous studies.

Scheduled Analgesic Regimen Improves Rehabilitation After Hip Fracture Surgery

Raymond Ping-Hong Chin FRCS, FHKAM, FHKCOS, Chin-Hung Ho FRCSE (Orth), FHKAM, FHKCOS, Lydia Po-Chee Cheung MSN

Postoperative pain often is the limiting factor in the rehabilitation of patients after hip fracture surgery.

No Difference in Gait Recovery After THA With Different Head Diameters: A Prospective Randomized Study

Luigi Zagra MD, Federica Anasetti MSEng, Luca Bianchi MD, Vittorio Licari MD, Roberto Giacometti Ceroni MD

Larger femoral heads are commonly presumed to improve joint stability and hip biomechanics; some studies have suggested they may hasten recovery of a normal gait. To our knowledge, no gait analysis studies have compared different size head diameters in THA.

Case Reports: Anteroinferior Acetabular Rim Damage Due to Femoroacetabular Impingement

Lisa M. Tibor MD, Reinhold Ganz MD, Michael Leunig MD

The most common location of labral tears and chondral damage in the hip is the anterosuperior region of the acetabulum, which is associated with pain in flexion and rotation. We describe a case series of patients with labral tears, ganglion formation, and chondromalacia isolated to the anteroinferior acetabulum. Clinically, patients had pain in extension and internal rotation.

Two or More Impingement and/or Instability Deformities Are Often Present in Patients With Hip Pain

Lisa M. Tibor MD, Gunnar Liebert MD, Reto Sutter MD, Franco M. Impellizzeri PhD, Michael Leunig MD

Damage to the hip can occur due to impingement or instability caused by anatomic factors such as femoral and acetabular version, neck-shaft angle, alpha angle, and lateral center-edge angle (CEA). The associations between these anatomic factors and how often they occur in a painful hip are unclear but if unaddressed might explain failed hip preservation surgery.

Do Young, Active Patients Perceive Advantages After Surface Replacement Compared to Cementless Total Hip Arthroplasty?

Robert L. Barrack MD, Erin L. Ruh MS, Michael E. Berend MD, Craig J. Della Valle MD, C. Anderson Engh MD, Javad Parvizi MD, FRCS, John C. Clohisy MD, Ryan M. Nunley MD

Potential advantages suggested but not confirmed for surface replacement arthroplasty (SRA) over THA include lower frequency of limp, less thigh pain, less limb length discrepancy, and higher activity.

Spontaneous Hip Labrum Regrowth After Initial Surgical D├ębridement

Geoffrey D. Abrams, Marc R. Safran MD, Hassan Sadri MD

Anecdotal evidence from second-look hip arthroscopies and animal studies has suggested spontaneous labral regrowth may occur after d├ębridement. However, these observations have not been systematically confirmed.
