Regulatory Approval and Compliance Risks: Si-Bone operates in a highly regulated environment, and failure to obtain or maintain necessary regulatory approvals, or non-compliance with regulations, could significantly impact its operations and financial performance.

Reimbursement Coverage Uncertainty: The company's financial success heavily depends on adequate insurance coverage and favorable reimbursement policies for its procedures and devices, which can change and create uncertainty for market adoption.

Competitive Landscape Pressures: Si-Bone faces significant competition from other medical device companies offering SI joint fusion systems or alternative treatments, which could lead to pricing pressure or loss of market share.
