The Sonoma HMRx™is a unique implant designed for midshaft humeral fractures. Proprietary TaperBody™ Technology facilitates a least invasive procedure with an entry portal that avoids the rotator cuff and articular surface. The device provides optional compression when actuated, and provides rigid, locked support for fracture fixation. The entire procedure is performed through small incisions, preserving the surrounding soft tissues, and minimizing loss of blood. See case studies and technical monograph for more detail.
Because traditional plating treatment of midshaft humeral fractures requires a lengthy incision, significant blood loss can result. Additionally, there is a risk of damaging the radial nerve when cutting through and detaching muscle in order to locate the plate on the midshaft fracture. Use of traditional intramedullary fixation in repairing a midshaft humeral fracture involves cutting through the rotator cuff, and inserting the device through the articular surface, which can cause impingement postoperatively. Dr. Carl Basamania offers a comparison of the Sonoma device to other types of fixation, and to non-operative treatment options.
The least-invasive approach used with the Sonoma HMRx™ device has several advantages: it avoids a large incision, spares involvement of the rotator cuff, reduces blood loss, and causes less trauma to the soft tissue around the bone. In turn, the soft tissue around the fracture is not disrupted, aiding in healing and reducing patient recovery time. See the surgical video and surgical animation demonstrating the HMRx™ in surgery.
