All Suture Biceps Tenodesis Has Greater Biomechanical Strength Than Metal Button Fixation.

Purpose: To evaluate the maximal load to failure, cyclic displacement, stiffness, and modes of failure of onlay subpectoral biceps tenodesis with an intramedullary unicortical metal button (MB) versus an inlay, all-suture Caspari-Weber (CW) technique.

Methods: Sixteen matched paired human cadaveric proximal humeri were randomly allocated for subpectoral BT with either CW or MB using a high-strength suture (N = 16; 8 male, 8 female, mean age = 82.5 years, range 62-99 years).

Biomechanical Comparison of Anterior Cervical Plate Fixation Versus Integrated Fixation Cage for Anterior Cervical Discectomy and Fusion.

Study Design: Cadaveric, biomechanic study.

Objective: To compare the range of motion profiles of the cervical spine following one-level anterior cervical discectomy and fusion (ACDF) constructs instrumented with either an interbody cage and anterior plate or integrated fixation cage in a cadaveric model.

Summary Of Background Data: While anterior plates with interbody cages are the most common construct of fixation in ACDF, newer integrated cage-plate devices seek to provide similar stability with a decreased implant profile.

Surgical Intervention vs. Radiation Therapy: The Shifting Paradigm in Treating Metastatic Spinal Disease.

The spine is one of the most common sites to which metastatic cancer is likely to spread and is one of the leading causes of morbidity and mortality in cancer patients. While no medical treatments have been definitively shown to extend the life expectancy of patients with spinal metastasis, interventional options may be the only viable option in improving outcomes. Currently, two main options exist: surgical resection and radiotherapy, with radiotherapy being the primary treatment modality.
