Anterior Inferior Iliac Spine Morphology Correlates With Hip Range of Motion: A Classification System and Dynamic Model

Iftach Hetsroni MD, Lazaros Poultsides MD, Asheesh Bedi MD, Christopher M. Larson MD, Bryan T. Kelly MD

The anterior inferior iliac spine (AIIS) contributes to hip dysfunction in patients with symptomatic impingement and resection of a prominent AIIS can reportedly improve function. However, the variability of the AIIS morphology and whether that variability correlates with risk of associated symptomatic impingement are unclear.

Increase of Cortical Bone After a Cementless Long Stem in Periprosthetic Fractures

Eduardo García-Rey MD, PhD, EBOT, Eduardo García-Cimbrelo MD, PhD, Ana Cruz-Pardos MD, PhD, Rosário Madero MS

Healing and functional recovery have been reported using an extensively porous-coated stem in Vancouver B2 and B3 periprosthetic fractures; however, loss of cortical bone has been observed when using these stems in revision surgery for aseptic loosening. However, it is unclear whether this bone loss influences subsequent loosening.

Validity and Reliability of the Paprosky Acetabular Defect Classification

Raymond Yu BM, BS, HB.MedSc, M.SurgSci, Jochen G. Hofstaetter MD, Thomas Sullivan BMa&CompSc(Hons), Kerry Costi BA, Donald W. Howie BM, BS, PhD, FRACS, Lucian B. Solomon MD, PhD, FRACS

The Paprosky acetabular defect classification is widely used but has not been appropriately validated. Reliability of the Paprosky system has not been evaluated in combination with standardized techniques of measurement and scoring.

What Are Predictors for Patients’ Quality of Life After Pelvic Ring Fractures?

Joerg H. Holstein MD, Antonius Pizanis MD, Daniel Köhler MD, Tim Pohlemann MD

Data from literature on predictors for patients’ quality of life after pelvic ring fractures are conflicting and based on small study populations.

Unstable Intertrochanteric Femur Fractures: Is There a Consensus on Definition and Treatment in Germany?

Matthias Knobe MD, Gertraud Gradl MD, Andreas Ladenburger MD, Ivan S. Tarkin MD, Hans-Christoph Pape MD

Extramedullary and intramedullary implants have improved in recent years, although consensus is lacking concerning the definition and classification of unstable intertrochanteric fractures, with uncertainties regarding treatment.

Does the Extent of Osteonecrosis Affect the Survival of Hip Resurfacing?

Satoshi Nakasone MD, Masaki Takao MD, PhD, Takashi Sakai MD, PhD, Takashi Nishii MD, PhD, Nobuhiko Sugano MD, PhD

The effect of the extent of osteonecrosis on the survival of hip resurfacing for osteonecrosis of the femoral head (ONFH) has not been well documented, but is a potentially important variable in the decision to perform resurfacing.

Cumulative Revision Rate is Higher in Metal-on-Metal THA than Metal-on-Polyethylene THA: Analysis of Survival in a Community Registry

Der-Chen T. Huang MD, Penny Tatman MPH, Susan Mehle BS, Terence J. Gioe MD

Metal-on-metal (MOM) THA bearing technology has focused on improving the arc of motion and stability and minimizing wear compared with traditional metal-on-polyethylene (MOP) bearing couples. It is unclear whether this more costly technology adds value in terms of improved implant survival.

Closed Bone Graft Epiphysiodesis for Avascular Necrosis of the Capital Femoral Epiphysis

George H. Thompson MD, Ethan S. Lea MD, MS, Kenneth Chin MD, Raymond W. Liu MD, Jochen P. Son-Hing MD, Allison Gilmore MD

Avascular necrosis (AVN) of the capital femoral epiphysis (CFE) after an unstable slipped capital femoral epiphysis (SCFE), femoral neck fracture or traumatic hip dislocation can result in severe morbidity. Treatment options for immature patients with AVN are limited, including a closed bone graft epiphysiodesis (CBGE). However, it is unclear whether this procedure prevents AVN progression.

Slipped Capital Femoral Epiphysis: Relevant Pathophysiological Findings With Open Surgery

Kai Ziebarth MD, Michael Leunig MD, Theddy Slongo MD, Young-Jo Kim MD, PhD, Reinhold Ganz MD

Traditionally arthrotomy has rarely been performed during surgery for slipped capital femoral epiphysis (SCFE). As a result, most pathophysiological information about the articular surfaces was derived clinically and radiographically. Novel insights regarding deformity-induced damage and epiphyseal perfusion became available with surgical hip dislocation.

Postoperative Improvement of Femoroacetabular Impingement After Intertrochanteric Flexion Osteotomy for SCFE

Takashi Saisu MD, PhD, Makoto Kamegaya MD, PhD, Yuko Segawa MD, PhD, Jun Kakizaki MD, Kazuhisa Takahashi MD, PhD

Patients with slipped capital femoral epiphysis (SCFE) may develop cam-type femoroacetabular impingement (FAI). Early management of FAI has been advocated for patients with symptomatic FAI. The various treatment options, including reorientation surgeries, realignment procedures, and osteoplasty, remain controversial.
