Segmentation by type classifies cortical bone screws into Self‑tapping, Self‑drilling, and Locking variants, each influencing market valuation differently. Self‑tapping screws, requiring pre‑drilled pilot holes, dominate the volume share because of their established use in conventional orthopedic fixation, contributing approximately 45 % of sales. Self‑drilling screws integrate a cutting tip, eliminating the pilot step; they capture around 35 % of the market, driven by operating‑room efficiency gains and reduced surgical time. Locking screws, featuring a threaded head that engages the plate, hold the premium segment at roughly 20 % of revenue, favored in complex spinal constructs where angular stability is critical. The differentiated pricing and adoption rates of these sub‑types collectively determine the total addressable market, reinforcing the importance of nuanced product‑level analysis within the broader Cortical Bone Screw market taxonomy.
