Stryker's InSpace subacromial balloon spacer two-year, Level 1 randomized controlled clinical study published in the Journal of Bone and Joint Surgery

InSpace implant demonstrated to be a viable option for patients with massive irreparable rotator cuff tears.*

KALAMAZOO, Mich., May 3, 2022 /PRNewswire/ -- Stryker (NYSE: SYK) announced today the publication of results from a multicenter, single-blinded, randomized controlled trial comparing Stryker's InSpace implant with partial repair for the treatment of full-thickness massive irreparable rotator cuff tears (MIRCTs) in the Journal of Bone and Joint Surgery (JBJS).

The comparative study evaluated the efficacy and safety of Stryker's InSpace implant with arthroscopic partial repair in patients with irreparable, posterosuperior MIRCTs.

Results of the two-year study demonstrated the InSpace implant as an appropriate alternative to partial repair in patients with MIRCTs. The study also revealed notable patient benefits including early functional recovery and pain relief combined with a shorter operative time.

MIRCTs are one of the most common causes of shoulder dysfunction.1,2,3 The InSpace balloon implant* is a breakthrough solution in the shoulder continuum of care that addresses MIRCTs and provides a new, simple surgical treatment option, allowing surgeons to better meet the needs of their patients.

"We are excited to see the high-quality data from the U.S. InSpace trial accepted and published by one of the most prestigious orthopaedic journals," said the lead investigator in the clinical study, Nikhil Verma, M.D. "These results demonstrating InSpace as a safe and effective option with earlier functional recovery, pain relief and shorter operative times are helping us change the game in shoulder surgery and creating better care for patients."

About the clinical study

The purpose of the Level 1 InSpace pivotal study – a prospective, single-blinded, multi-center, randomized, controlled trial was to assess the safety and effectiveness of the InSpace Implant (IS) compared to Partial Repair (PR). The study evaluated 184 (n=93 IS; n=91 PR) randomized eligible patients with symptomatic massive full thickness rotator cuff tears that failed non-operative management, through 24 months of follow-up. 1

About the balloon

InSpace is a biodegradable implant designed to restore the subacromial space, providing a less invasive solution compared to other surgical treatment options that require fixation devices or grafts and has been demonstrated to improve shoulder motion and function.4

*The InSpace™ subacromial tissue spacer system is indicated for the treatment of patients with massive, irreparable full-thickness torn rotator cuff tendons due to trauma or degradation with mild to moderate gleno-humeral osteoarthritis in patients greater than or equal to 65 years of age whose clinical conditions would benefit from treatment with a shorter surgical time compared to partial rotator cuff repair.
