What Is A Spinal Surgery?

What Is a Spinal Surgery? A Direct Definition

"Spinal Surgery" certification, in the context this site covers, refers specifically to Certification in Spine Surgery administered by the American Board of Spine Surgery (ABSS). It is not a generic label for the specialty of performing spine operations - it is a formal, two-part credentialing process built around a written examination and an oral examination, both of which a candidate must pass to hold full ABSS certification.

Because several credentials in medicine share overlapping abbreviations, it's worth being precise: this article, and every other resource on this site, describes the ABSS pathway only. If you're comparing programs, always confirm you're looking at ABSS materials directly through americanboardofspinesurgery.org or the exam administration page at Prometric.

For a broader conceptual walkthrough, see What Is Spinal Surgery? and Spinal Surgery Meaning, which unpack the terminology in more depth than this overview.

Two Exams, One Credential: Part I and Part II

ABSS certification is structured in sequence. You cannot skip ahead or take Part II before passing Part I, and full certification isn't awarded until both are complete.

Part I: The Written Examination

Part I is a computerized, proctored, closed-book exam administered by the Professional Testing Corporation through Prometric testing centers. A detail worth internalizing before test day: unscheduled breaks do not stop the exam clock. If you step away, your allotted time keeps running, so pacing discipline matters as much as content knowledge.

Part II: The Oral Examination

Part II requires that you've already passed Part I and accumulated two years of active practice. It uses an oral case review format, and the board describes a virtual delivery model - meaning candidates should expect a remote, conversational case-based assessment rather than a multiple-choice format. This is a fundamentally different skill set from Part I: you're demonstrating clinical reasoning and judgment in real time rather than selecting answers from a list.

Because the two parts test such different skills, candidates researching How Hard Is the Spinal Surgery Exam? Complete Difficulty Guide 2026 should treat Part I preparation and Part II preparation as separate projects, not one continuous study block.

The Four Domains Tested on the Written Exam

The ABSS written outline is organized into four official top-level sections. Knowing these domains by name - and by what they actually test - is the single most useful thing you can do before opening a study resource.

For a section-by-section breakdown with more granular topic lists, see Spinal Surgery Exam Domains 2026: Complete Guide to All 4 Content Areas.

Who Can Sit for the Exam

ABSS eligibility is deliberately narrow - this isn't an open-entry exam. To qualify, candidates generally need:

• Approved spine fellowship training of at least 12 months, or accepted equivalent residency training
• An unrestricted medical license, subject to the published federal-service exception
• Qualifying orthopedic or neurological surgery credentials
• Two supporting letters

There's a useful nuance here: passing the relevant primary-board written examination can satisfy the entry credential requirement at the time of application, but full qualifying primary-board certification must be in hand before ABSS certification is actually awarded. In other words, you may be able to sit for the ABSS written exam while your primary-board process is still finishing, but you won't receive your ABSS certificate until that primary certification is complete.

This eligibility structure is detailed further in Spinal Surgery Requirements 2026: Eligibility, Prerequisites & How to Qualify, which is worth reading before you invest in Part I registration.

Registration, Delivery, and Fees

The financial and logistical mechanics are straightforward once broken down:

Staying Certified: Recertification

ABSS certification is valid for 10 years, not indefinitely. To maintain it, certificants must complete a recertification process that includes:

• A formal application
• A $250 recertification fee
• Continuing education documentation
• Current, valid medical licensure
• Three professional references
• A written or oral assessment component

This is a meaningfully lighter lift than the initial certification process, but it still requires planning - particularly gathering references and continuing education records well ahead of your renewal window rather than scrambling near the ten-year mark.

Who Actually Looks for This Credential

ABSS certification signals to hospital credentialing committees, spine-focused practice groups, and surgical partners that a surgeon has completed dedicated spine fellowship training and passed a structured, spine-specific assessment beyond general orthopedic or neurosurgical board certification. It functions as an additional layer of subspecialty verification rather than a replacement for primary board certification.

Surgeons researching career impact often ask whether the credential changes hiring conversations or compensation discussions. For a grounded look at that question, see Spinal Surgery Salary Guide 2026: Complete Earnings Analysis and Is the Spinal Surgery Certification Worth It? Complete ROI Analysis 2026. If you're evaluating job postings and want to understand how the credential is referenced in practice listings, Spinal Surgery Jobs covers that landscape directly.

Mapping a Study Plan to the Content Outline

Because the written exam is organized around four fixed domains, the most efficient preparation approach is to build your schedule around those sections rather than a generic week-by-week template. Allocate more time to Surgical Sciences and Clinical Sciences early, since they carry the heaviest clinical-reasoning load, then reserve later weeks for Basic Sciences review and General Topics, which tend to reward focused, shorter review sessions closer to test day.
