Surgical Planning Associates

Surgical Planning Associates (SPA) is a Boston-based medical technology company specializing in surgical navigation and preoperative planning solutions for orthopedic procedures. The company's flagship product, the HipInsight System, is the world's first FDA-cleared mixed reality navigation platform designed specifically for total hip arthroplasty. The system utilizes Microsoft HoloLens 2 mixed reality glasses to provide surgeons with real-time 3D holographic overlays of patient-specific anatomy, surgical instruments, and preoperative plans, effectively giving surgeons "x-ray vision" during surgery. HipInsight combines cloud-based preoperative planning with intraoperative guidance, achieving accuracy within 3 degrees of target anteversion and inclination. The platform integrates seamlessly into existing surgical workflows and can be deployed in under 5 minutes in the operating room. With over 11,000 hip replacement surgeries performed using SPA's technology across four continents, the company has established itself as a leader in digital surgery solutions. SPA maintains a co-marketing partnership with Zimmer Biomet and serves hospital systems and surgical centers seeking to improve implant positioning precision and surgical outcomes.
