An early analysis of polyetheretherketone (PEEK) plates for the surgical stabilization of rib fractures: A pilot study

Background: Surgical stabilization of rib fractures (SSRF) is a viable treatment option for rib fracture patients. Polyetheretherketone (PEEK) plates have become available for SSRF. The objective of this pilot study was to examine the use of PEEK plates for SSRF.

Methods: A prospective, observational, multi-center study of patients undergoing SSRF with PEEK plates from 4/23 through 2/24. Standard indications for SSRF were followed and the decision to use PEEK plates was left to the discretion of the treating surgeon. Basic demographics were obtained. Outcomes included the number of rib fractures stabilized with PEEK plates, complications related to SSRF, and 6-month follow-up with chest computed tomography (CT) to assess healing of PEEK repaired fracture sites, identified as complete or incomplete union. Patients also answered a five-question quality-of-life survey regarding mobility, self-care, usual activities, chest pain/discomfort, and anxiety/depression. Answers were scaled 1 to 5 (1=worse condition possible; 5=best possible condition). Patients rated their health on a scale of 0 to 100 (100=closet to their health preinjury). All data was reported as descriptive.

Results: Forty-six patients were included. Average age was 57(±16) years; 82.6 % were male. Median ISS was 18 (IQR 14,29) and median chest-AIS was 4 (IQR 3,4). 219 rib fractures were stabilized with PEEK plates. Sixteen (34.8 %) had a combination (PEEK + titanium) procedure. Three patients had a complication: one required a second surgery for additional SSRF, and two patients were readmitted. Twenty-seven patients were surveyed at 6 months, and 19 agreed to CT scan. Eighty PEEK repaired rib fractures were assessed for healing. 80 % of fractures had complete union and no hardware failure. Quality-of-life survey averaged >4.5/category and mean overall health was 89.

Conclusion: PEEK plates for SSRF are safe and effective, allowing for adequate rib fracture healing and are associated with positive patient reported outcomes.
