Company Overview

Pinnacle Spine Group is a Texas-based company established by Sowell & Company, a privately held investment firm, and led by Zach Sowell, President, and Russell W. Nelson, M.D., Chief Medical Officer. The company has pioneered the novel concept of placing bone graft material into an implanted device in situ in the spine to maximize graft material volume within the disc space to allow for optimal contact with vertebral endplates – a critical element in positive fusion outcomes.

Pinnacle Spine Group was the first company to bring to market a patented spinal fusion system with integrated in situ graft delivery capabilities. Today, the InFill® family of Interbody Fusion Systems features:

  • Larger load-bearing surface area for maximum contact with the epiphyseal ring, designed to reduce subsidence,
  • Larger graft chambers to accommodate higher volumes of bone graft material
  • A unique tooth geometry that prevents implant displacement post insertion
  • Unique graft hooks within the graft chamber to secure any pre-packed bone material
  • Vents along the anterior wall to allow for the flow of bone graft into the anterior disc space
  • A threaded port hole on the proximal end of the implant that allows for a secure connection to the inserter, and for access for the graft delivery tubes to the graft chamber
