Which Implant Is Better for Treating Reverse Obliquity Fractures of the Proximal Femur: A Standard or Long Nail?

Güvenir Okcu MD, Nadir Ozkayin MD, Cemil Okta MD, Ismet Topcu MD, Kemal Aktuglu MD

Reverse obliquity fractures of the proximal femur have biomechanical characteristics distinct from other intertrochanteric fractures and high implant failure rate when treated with sliding hip screws. Intramedullary hip nailing for these fractures reportedly has less potential for cut-out of the lag screw because of their loadbearing capacity when compared with extramedullary implants. However, it is unclear whether nail length influences healing.

Is the Bone-bonding Ability of a Cementless Total Hip Prosthesis Enhanced by Alkaline and Heat Treatments?

Kazutaka So MD, PhD, Ayumi Kaneuji MD, PhD, Tadami Matsumoto MD, PhD, Shuichi Matsuda MD, PhD, Haruhiko Akiyama MD, PhD

Cementless total hip arthroplasty (THA) implants using alkaline and heat treatments were developed to enhance bone bonding. Although bone-bonding ability of the alkali- and heat-treated titanium surface has been demonstrated in animal studies, it remains unknown whether it enhances or provides durable bone bonding in humans.

The Natural History of Inflammatory Pseudotumors in Asymptomatic Patients After Metal-on-metal Hip Arthroplasty

Sulaiman A. Almousa MBBS, Nelson V. Greidanus MD, MPH, Bassam A. Masri MD, Clive P. Duncan MD, MSc, Donald S. Garbuz MD, MHSc

Although pseudotumors have been reported in 32% of asymptomatic metal-on-metal hips, the natural history of asymptomatic pseudotumors is unknown.

High Survivorship With a Titanium-encased Alumina Ceramic Bearing for Total Hip Arthroplasty

James A. D’Antonio MD, William N. Capello MD, Marybeth Naughton BS

Although ceramic-on-ceramic bearings for total hip arthroplasty (THA) show promising results in terms of bearing-surface wear, fracture of the bearing, insertional chips, and squeaking remain a concern.

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

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.
