Case Report: Osteoid Osteoma of the Acetabulum Treated With Arthroscopy-assisted Radiofrequency Ablation

Damiano Ricci MD, Guido Grappiolo MD, Matthew Franco BA, Federico Della Rocca MD

Osteoid osteomas consist of a nidus surrounded by reactive sclerotic bone. The diagnosis typically is based on imaging and clinical presentation involving nocturnal pain. Removal of the lesion is essential and currently is performed mainly with image-guided, minimally invasive techniques. We describe a case involving an osteoid osteoma of the acetabular fossa, treated with arthroscopy-assisted radiofrequency ablation.

Unstable SCFE: Review of Treatment Modalities and Prevalence of Osteonecrosis

Ira Zaltz MD, Geneva Baca PhD, John C. Clohisy MD

The treatment of unstable slipped capital femoral epiphysis (SCFE) is rapidly evolving with the ability to correct epiphyseal alignment using the modified Dunn technique. Adopting a new treatment method depends on confirming that it achieves its goals, produces few, nonserious complications with no lasting sequelae, and improves the natural history of the disorder compared with known treatment methods. As such, the rates of osteonecrosis and complications after current treatments of unstable SCFE must be compared with those of newer surgical techniques.

The Fate of Hips That Are Not Prophylactically Pinned After Unilateral Slipped Capital Femoral Epiphysis

Yaser M. K. Baghdadi MD, A. Noelle Larson MD, Rafael J. Sierra MD, Hamlet A. Peterson MD, Anthony A. Stans MD

The indications for prophylactic pinning of the contralateral hip after unilateral slipped capital femoral epiphysis (SCFE) remain controversial in part because the natural history of the contralateral hip is unclear.

New Radiographic Index for Evaluating Acetabular Version

Hiroshi Koyama MD, Hironobu Hoshino MD, PhD, Daisuke Suzuki MD, Shoichi Nishikino MD, Yukihiro Matsuyama MD, PhD

Several qualitative radiographic signs have been described to assess acetabular retroversion. However, quantitative assessment of acetabular version would be useful for more rigorous research purposes and perhaps to diagnose and treat hip disorders.

Case Report: Painless Chronic Liner Dissociation of a Total Hip Arthroplasty

Jorm M. Nellensteijn MD, David R. Nellensteijn MD, Tjitte Jong MD

Dislocation or liner dissociation of a total hip prosthesis usually results in pain and discomfort. Although several reports describe chronic dislocation and its treatment, chronic liner dissociation is an unreported complication.

Smoking May Be a Harbinger of Early Failure With Ultraporous Metal Acetabular Reconstruction

Adolph V. Lombardi MD, Keith R. Berend MD, Joanne B. Adams BFA, Ryan C. Jefferson BS, Michael A. Sneller BS

Smoking is considered a risk factor for surgical complications in total hip arthroplasty (THA) and has been linked to a higher rate of aseptic loosening in uncemented acetabular components. Acetabular reconstruction with newer ultraporous metals in both complex primary and revision THA has increased survivorship but it is unclear whether smoking affects survival of these implants.

Growth Plate Alteration Precedes Cam-type Deformity in Elite Basketball Players

Klaus A. Siebenrock MD, Anna Behning MD, T. Charles Mamisch MD, Joseph M. Schwab MD

Vigorous sporting activity during the growth years is associated with an increased risk of having a cam-type deformity develop. The underlying cause of this osseous deformity is unclear. One may speculate whether this is caused by reactive bone apposition in the region of the anterosuperior head-neck junction or whether sports activity alters the shape of and growth in the growth plate. If the latter is true, then one would expect athletes to show an abnormal shape of the capital growth plate (specifically, the epiphyseal extension) before and/or after physeal closure.

The Shape of the Proximal Femur Influences Acetabular Wear Patterns Over Time

Jonathan J. Streit MD, Ari Levine MD, Ian J. Barrett BS, Daniel R. Cooperman MD, Victor Goldberg MD

Femoroacetabular impingement has been proposed as a cause of early osteoarthritis, but it is not known how this develops over time or whether the shape of the proximal femur influences this risk.

Is Limited Incision Better Than Standard Total Hip Arthroplasty? A Meta-analysis

Joseph T. Moskal MD, Susan G. Capps PhD

The literature comparing limited incision and standard incision THAs is confusing regarding whether limited incision THA improves short-term recovery without compromising long-term durability and survival. Further, previously published meta-analyses cannot conclude that limited incision THA is better. With new data, we seek to discover if the answers now exist.

Case Reports: Acetabular Damage After Mild Slipped Capital Femoral Epiphysis

Cara Beth Lee MD, Travis Matheney MD, Yi-Meng Yen MD, PhD

Slipped capital femoral epiphysis (SCFE) is a common hip problem in adolescents that results in a cam-type femoroacetabular impingement (FAI) deformity. Although the treatment for mild (slip angle of 0°–30°) and moderate (slip angle of 31°–60°) SCFE has historically been in situ fixation, recent studies have demonstrated impingement-related articular damage, irrespective of slip severity. Our series confirms previous reports that acetabular chondral injury occurs in mild to low-moderate (slip angle of ≤ 40°) SCFE.
