Myxopapillary Ependymoma of the Sacrum.

Myxopapillary ependymoma presenting as a highly destructive lesion in the sacrum is rare but should be included in the differential diagnosis.

Intraoperative Brachytherapy Combined With Adjuvant Radiotherapy Shows Equal Results in the Treatment of Leiomyosarcoma on the Extremities Compared to Adjuvant Radiotherapy Only - A Multicentric Retrospective Analysis.

Background/aim: Leiomyosarcomas account for 2-10% of all extremity soft tissue sarcomas. The role of intraoperative brachytherapy as an additive booster therapy is not clearly defined. This study focused on the additive value of brachytherapy in the treatment of leiomyosarcomas on the extremities.

Chondroid Lipoma Mimicking Malignancy.

A chondroid lipoma is a rare benign adipocytic neoplasm, containing a chondromyxoid matrix, that may mimic a myxoid liposarcoma and myxoid chondrosarcoma.

The Influence of Personalised Sarcoma Care (PERSARC) Prediction Modelling on Clinical Decision Making in a Multidisciplinary Setting.

Background: With soft-tissue sarcoma of the extremity (ESTS) representing a heterogenous group of tumors, management decisions are often made in multidisciplinary team (MDT) meetings. To optimize outcome, nomograms are more commonly used to guide individualized treatment decision making.

Purpose: To evaluate the influence of Personalised Sarcoma Care (PERSARC) on treatment decisions for patients with high-grade ESTS and the ability of the MDT to accurately predict overall survival (OS) and local recurrence (LR) rates.

Immune Checkpoint Inhibitory Therapy in Sarcomas: Is There Light at the End of the Tunnel?

Soft tissue and bone sarcomas are a very heterogeneous group of tumors with many subtypes for which diagnosis and treatment remains a very challenging task. On top of that, the treatment choices are limited, and the prognosis of aggressive sarcomas remains poor. Immune checkpoint inhibitors (ICIs) have drawn a lot of attention last years because of their promising response rates and their durable effects.

Outcome and EBRA migration analysis of a reconstruction cage in acetabular revision arthroplasty: a clinical and radiological study.

Purpose: Restoration cages and bone allografts have been proposed to manage severe acetabular bone defects. We aimed to investigate the migration behaviour of a restoration cup and impacted allograft bone in severe acetabular defects with Einzel-Bild-Röntgen-Analyse (EBRA).

Methods: Applying a retrospective study design, 64 cases treated between 2009 and 2016 were reviewed.

Follow-up Strategies for Primary Extremity Soft-tissue Sarcoma in Adults: A Systematic Review of the Published Literature.

Aim: Follow-up strategies for primary extremity soft-tissue sarcomas (eSTS) in adults were evaluated in a systematic review of the published literature.

Material And Methods: The published literature was reviewed using PubMed. Of 136,646 studies published between 1985 and 2019, 78 original articles met the inclusion criteria.

Clinical Outcome of Surgically Treated Leiomyosarcoma of the Extremities: A Retrospective Overview.

Aim: This study was interested in extremity leiomyosarcoma with focus on clinical outcome after surgery with or without adjuvant therapy.

Patients And Methods: A retrospective case series of all patients with leiomyosarcoma, surgically treated between 2000 and 2015 and a minimum follow-up of 2 years, was drawn from institutional databases in Belgium and the Netherlands. Postoperative complications were reported with the Radiation Therapy Oncology Group (RTOG) and the Henderson classification.

The Anatomical Course of the Lateral Femoral Cutaneous Nerve in Relation to Various Skin Incisions Used for Primary and Revision Total Hip Arthroplasty With the Direct Anterior Approach.

Background: Although the direct anterior approach (DAA) has become a standard for primary and revision total hip arthroplasty, it involves a high risk of injuring the lateral femoral cutaneous nerve (LFCN). The aim of this study is to examine the course of the LFCN in relation to various skin incisions and approach extensions used for the DAA.

Methods: We obtained 44 limbs and hemipelves from 22 formalin-preserved cadavers, in which LFCN was identified.

Femoral anteversion measurement : evaluation of inter- and intraobserver reliability.

The aim of this study was to evaluate the inter- and intraobserver reliability of a CT-based femoral anteversion measurement. 17 CT scans showing an abnormal anteversion on one side were presented to 6. Three measurements of all scans were obtained : two bilateral measurements and a third measurement with a flipped CT scan.

Pioneer Female Orthopedic Surgeons as Role Models.

Maud Forrester-Brown in the United Kingdom (1921), Marika Daniilidou in Greece (1932), Ruth Jackson in the United States (1932), Loris Figgins in Australia (1957), and Evalina Burger in South Africa (1993) all chose to specialize in orthopedics. Although there are dynamic female leaders in orthopedic surgery, the field continues to present obstacles to women. Role models, mentors, and exposure to the field have been lacking for women.
