New research

  1. Apparent diffusion coefficient metrics for treatment response assessment in soft tissue sarcoma: Reproducibility and prognostic value of whole-tumor and sub-regional analysis.

    Skeletal Radiology · Jul 30 2026 · PubMed

    In 23 sarcoma patients, post-treatment whole-tumor ADC values were highly reproducible and strongly predicted pathologic response to neoadjuvant radiotherapy, whereas sub-regional and longitudinal ADC changes were less reliable.

  2. En-bloc spondylectomy at the thoracolumbar junction for primary and metastatic spinal tumors: indications, outcomes and complications in a consecutive series of 22 patients.

    European Spine Journal · Jul 24 2026 · PubMed

    In 22 patients, en-bloc thoracolumbar spondylectomy for spinal tumors achieved good oncologic control (5-year overall survival 64%) but high morbidity, with marginal margins seeming adequate while intralesional margins were linked to recurrence.

  3. Cement augmentation of pedicle screw constructs as a modifier of hardware failure risk in instrumented metastatic spine surgery: a systematic review and meta-analysis.

    European Spine Journal · Jun 03 2026 · PubMed

    Meta-analysis suggests cement-augmented pedicle screws may lower hardware failure rates versus conventional fixation in metastatic spine surgery (4.3% vs 12.5%), but evidence certainty is low.

Recent reviews

  1. The Musculoskeletal Tumor Society Clinical Practice Guideline on the Management of Metastatic Humeral Disease.

    Journal of the American Academy of Orthopaedic Surgeons · May 15 2024 · PubMed

    This AAOS-endorsed guideline offers seven evidence-based recommendations for surgical management of metastatic, myeloma, and lymphoma disease of the humerus.

  2. Endoprosthetic Reconstruction of the Upper Extremity in Oncologic Surgery.

    Journal of the American Academy of Orthopaedic Surgeons · Apr 15 2020 · PubMed

    This review shows that despite complex regional anatomy, endoprosthetic reconstruction of the scapula and humerus yields excellent mid- to long-term pain relief and function for both oncologic and non-oncologic bone loss.
