Total Hip Arthroplasty Versus Hemiarthroplasty for Displaced Femoral Neck Fractures: Meta-analysis of Randomized Trials

Ligang Yu MM, Yan Wang MD, Jiying Chen MD

Most patients with displaced femoral neck fractures are treated by THA and hemiarthroplasty, but it remains uncertain which if either is associated with better function and lower risks of complications.

Measuring Acetabular Component Version After THA: CT or Plain Radiograph?

Benjamin McArthur MD, Michael Cross MD, Christina Geatrakas MD, David Mayman MD, Bernard Ghelman MD

Although cross-table lateral radiographs are commonly used to measure acetabular component version after THA, recent studies suggest that CT-based measurement is more accurate. This has been attributed to variations in pelvic tilt, pelvic rotation, and component inclination. Furthermore, it has been suggested, based on limited data, that even with ideal positioning of the cross-table lateral radiograph, CT remains the more accurate modality.

High Survival of Dome Pelvic Osteotomy in Patients with Early Osteoarthritis from Hip Dysplasia

Takashi Sakai MD, PhD, Takashi Nishii MD, PhD, Masaki Takao MD, PhD, Kenji Ohzono MD, PhD, Nobuhiko Sugano MD, PhD

The Chiari osteotomy reportedly has a 60% to 91% survival rate at a minimum 20 years followup. The dome pelvic osteotomy (DPO) has the advantage of allowing a larger weightbearing surface, and congruity in the sagittal plane presumably would reduce the joint contact stress and perhaps increase longevity.

High Rate of Ceramic Sandwich Liner Fracture

Ronny Lopes MD, Jean M. Philippeau MD, Norbert Passuti MD, PhD, François Gouin MD, PhD

Ceramic bearing surfaces for THA were introduced to reduce the risk of wear. However, owing to liner fracture in some of the early series and presumption that the fractures were the result of the modulus mismatch of the implant and the bone, a ceramic sandwich liner with lower structural rigidity was introduced. Fractures of these devices also were reported subsequently, although the incidence is unclear and it is unknown whether there are any risk factors associated with the fractures.

Is Helical Blade Nailing Superior to Locked Minimally Invasive Plating in Unstable Pertrochanteric Fractures?

Matthias Knobe MD, Wolf Drescher MD, PhD, Nicole Heussen MD, Richard Martin Sellei MD, Hans-Christoph Pape MD

Technical advancements have produced many challenges to intramedullary implants for unstable pertrochanteric fractures. Helical blade fixation of the femoral head has the theoretical advantages of higher rotational stability and cutout resistance and should have a lower rate of reoperation than a locked plating technique.

Anatomic Mapping of Short External Rotators Shows the Limit of Their Preservation During Total Hip Arthroplasty

Yoshiaki Ito MD, Isao Matsushita MD, PhD, Hiroki Watanabe MD, PhD, Tomoatsu Kimura MD, PhD

The direct anterior approach in THA requires no detachment of muscle insertions. However, damage to the short external rotator muscles may occur when attempting to elevate the femur for exposure. Although the anatomic insertions of these muscles are approximately known, there are no quantitative data regarding their locations.

High Rates of Sexual and Urinary Dysfunction After Surgically Treated Displaced Pelvic Ring Injuries

Adekoyejo A. Odutola FRCS(Orth), Omar Sabri FRCS(Orth), Ruth Halliday, Timothy J. S. Chesser FRCS(Orth), Anthony J. Ward FRCS

Pelvic ring injuries may be associated with genitourinary injury (GUI) and result in urinary or sexual dysfunction.

Operating Room Traffic is a Major Concern During Total Joint Arthroplasty

Pedram Panahi MBBS, Mitchell Stroh BS, David S. Casper BS, Javad Parvizi MD, FRCS, Matthew S. Austin MD

Periprosthetic joint infection (PJI) is a challenging complication associated with total joint arthroplasty (TJA). Traffic in the operating room (OR) increases bacterial counts in the OR, and may lead to increased rates of infection.

Which is the Best Alternative for Displaced Femoral Neck Fractures in the Elderly?: A Meta-Analysis

Hongwei Gao MD, Zhonghao Liu MD, Deguo Xing MD, Mingzhi Gong MD, PhD

Treatment of displaced femoral neck fractures includes internal fixation and arthroplasty. However, whether arthroplasty or internal fixation is the primary treatment for displaced femoral neck fractures in elderly patients remains a subject for debate. The literature contains conflicting evidence regarding rates of mortality, revision surgery, major postoperative complications, and function in elderly patients with displaced femoral neck fractures treated either by internal fixation or arthroplasty (either hemiarthroplasty or THA).

Persistent Impairment After Surgically Treated Lateral Compression Pelvic Injury

Martin F. Hoffmann MD, Clifford B. Jones MD, Debra L. Sietsema RN, PhD

Recently, fixation of lateral compression (LC) pelvic fractures has been advocated to improve patient comfort and to allow earlier mobilization without loss of reduction, thus minimizing adverse systemic effects. However, the degree of acceptable deformity and persistence of disability are unclear.
