- 175 questions in four ~44-question blocks, roughly 4 hours total, one testing date each August.
- Registration and application fees are $800 each; late fees add $160 per item, non-refundable.
- Since 2025, ABS diplomates route through ABPS alongside ABPS diplomates for the Hand Subspecialty Certificate.
- No penalty for guessing - every one of the 175 items should get an answer.
Exam Mechanics at a Glance
The Hand Surgery Examination (HSE) is jointly developed by the Joint Committee on Hand Surgery, representing the American Boards of Orthopaedic Surgery and Plastic Surgery. The American Board of Plastic Surgery (ABPS) issues the Hand Subspecialty Certificate, while the American Board of Orthopaedic Surgery (ABOS) handles scoring and analysis. If you only remember one structural fact for exam day, remember this: 175 multiple-choice questions, split into four blocks of approximately 44 questions each, administered at 60-minute intervals.
Total seated testing time runs about 4 hours, with an optional 15-minute tutorial before the first block and an optional 15-minute break somewhere in the middle. The exam is computer-delivered at Pearson Professional Centers on a single annual date in August - there is no rolling window, no retake next month if you miss it. No notes, textbooks, personal electronics, or scratch paper are allowed at the workstation.

Fees, Deadlines, and the Application Timeline
Money and paperwork trip up candidates almost as often as content gaps do. Here's the full fee structure in one place:
| Item | Amount | Notes |
|---|---|---|
| Exam registration fee | $800 | Non-refundable, credit card only |
| Application fee | $800 | Non-refundable, credit card only |
| Late fee (per item) | $160 | Applies to registration or application separately |
| Withdrawal fee | $520 | Charged if you withdraw after registering |
| Hand recertification/renewal fee | $500 | Separate from Continuous Certification fee |
| ABPS Continuous Certification | $410 | Required to keep the certificate active |
All fees are non-refundable and must be paid by credit card - there's no invoicing or check option. A full breakdown of how these costs stack up over a career, including recertification cycles, is available in HSE Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Since 2025, candidates can sit for the HSE immediately after completing a 12-month ACGME-accredited hand fellowship - before primary board certification is even finalized - but only after a Preliminary Fellowship Program Director Recommendation unlocks the registration form.
Also new as of the 2024 ABMS ruling: the American Board of Surgery is now a qualifying board under ABPS, so from 2025 onward, ABS diplomates pursue the Hand Subspecialty Certificate through ABPS just like plastic surgery diplomates, without needing to maintain primary general surgery certification separately. If you're unsure whether you meet the underlying eligibility chain - fellowship length, practice months, case list window, peer review - read HSE Requirements 2026: Eligibility, Prerequisites & How to Qualify before you spend a single study hour.
The Seven Domains, Distilled
The HSE draws from seven content domains. Knowing the exact domain names - and which subtopics live inside each - lets you map your weak spots instead of studying blindly. A full breakdown of weighting and subtopics is in HSE Exam Domains 2026: Complete Guide to All 7 Content Areas, but here's the condensed version.
Domain 1: Basic Science
Anatomy, biomechanics, biology/physiology/healing, pathology and tumors, and diagnostic reasoning form the foundation layer - expect questions that test structural relationships as much as memorized facts.
- Intrinsic/extrinsic muscle anatomy and pulley systems
- Tendon and bone healing timelines
- Soft tissue tumor differentials of the hand
Domain 2: Bone and Joint
Fractures and dislocations dominate this domain, but arthritis, contractures, wrist instability patterns, and osteonecrosis (Kienböck's, Preiser's) all show up regularly.
- Scaphoid and distal radius fracture management decision points
- Perilunate and SLAC/SNAC progression staging
- Dupuytren's contracture staging and treatment options
Domain 3: Nerve - Muscle - Tendon
Peripheral nerve injury classification, central nervous system considerations, brachial plexus patterns, and muscle-tendon pathology are tested with an emphasis on localization and timing of intervention.
- Seddon and Sunderland nerve injury classifications
- Brachial plexus birth palsy vs. traumatic patterns
- Tendon transfer principles for nerve palsies
Domain 4: Wound Management
Physical agents, coverage options, nailbed/fingertip injuries, and amputation-level decision-making are core here.
- Flap selection hierarchy by defect size and location
- Nailbed repair technique and prognosis
- Replantation vs. revision amputation criteria
Domain 5: Vascular
Injury and repair, reconstruction, ischemia, vascular malformations, replantation, and lymphedema round out a domain that rewards precise anatomic knowledge.
- Ischemia time thresholds by tissue type
- Vascular malformation classification (Mulliken/Glowacki)
- Replantation indications and contraindications
Domain 6: Rehabilitation
Prosthetics, orthotics, and physical modalities/therapy are smaller in volume but consistently appear, especially around post-operative protocols.
- Splinting positions after tendon repair vs. nerve repair
- Prosthetic options for partial hand vs. wrist disarticulation
Domain 7: Miscellaneous
Congenital anomalies, infection, dystrophy/pain (including CRPS), ethics and professionalism, and anesthetics are grouped here - don't underweight this domain just because it's labeled "miscellaneous."
- Congenital hand anomaly classification systems
- Flexor tenosynovitis and deep space infection management
- Regional anesthesia blocks specific to hand procedures
High-Yield Topics You Cannot Skip
Across all seven domains, a handful of topics recur disproportionately on past exam patterns and in candidate feedback. If your study time is limited, prioritize:
- Distal radius and scaphoid fracture classification and treatment algorithms (Domain 2)
- Flexor tendon zone injuries and repair/rehab protocols (Domains 3 and 6)
- Nerve compression syndromes - carpal tunnel, cubital tunnel, radial tunnel (Domain 3)
- Flap coverage decision trees for fingertip and dorsal hand defects (Domain 4)
- Replantation indications, ischemia windows, and postoperative monitoring (Domain 5)
- Congenital anomaly classification (Domain 7)
- Infection patterns unique to the hand - felon, paronychia, flexor sheath infection (Domain 7)
These topics reward pattern recognition over rote memorization, which lines up with how the exam is written - see the next section on question style.
Question Style: What the Stem Actually Tests
The HSE is not a definitions quiz. Question stems typically present a clinical vignette - mechanism of injury, exam findings, sometimes imaging description - and ask for the best next step, most likely diagnosis, or most appropriate management. Because there's no partial credit and no penalty for guessing, the strategic move is to eliminate obviously wrong distractors first, then commit to an answer within each 60-minute block rather than leaving items blank.
For a broader discussion of how the exam's difficulty compares to other subspecialty boards and where candidates typically lose points, read How Hard Is the HSE Exam? Complete Difficulty Guide 2026. If you want data-informed context on outcomes rather than anecdote, HSE Pass Rate 2026: What the Data Shows lays out what's publicly known.
Final-Weeks Review Sequencing
Generic study techniques only matter if they're mapped to HSE content. In the final stretch before your August test date, sequence review by domain weight and personal weak spots rather than alphabetically.
Bone and Joint + Basic Science
- Drill fracture classification systems and healing timelines together since they overlap conceptually
- Use timed question blocks that mimic the 44-question/60-minute format
Nerve - Muscle - Tendon + Vascular
- Pair nerve injury classification with replantation ischemia windows - both hinge on timing thresholds
- Review brachial plexus patterns with anatomic diagrams, not just text
Wound Management + Rehabilitation
- Run flap-selection scenarios end-to-end, from injury to postoperative splinting
- Cross-reference nailbed and fingertip injury management with amputation-level decisions
Miscellaneous domain + full-length mixed blocks
- Don't skip congenital anomalies and ethics/professionalism just because volume feels lower
- Take full 175-question timed simulations to build stamina for the 4-hour session
For a structured week-by-week plan that goes deeper than this summary, see HSE Study Guide 2026: How to Pass on Your First Attempt. Running full-length timed sets on our practice test platform is the closest simulation you'll get to the actual four-block structure.
Certificate Rules Worth Memorizing
Passing the exam is only part of the certification lifecycle. A few rules catch candidates off guard:
- Exam results are valid for five years, and candidates remain admissible for five calendar years, extendable by four more, up to a nine-year ABMS limit overall.
- A failing result means repeating the entire 175-question exam - there's no partial retest of weak domains.
- The Hand Subspecialty Certificate itself is valid for five years from issuance and is contingent on ABPS Continuous Certification participation.
- The certificate expires automatically if your primary plastic surgery (or now, ABS-qualifying) certificate expires.
- You may not advertise subspecialty status until the certificate is actually issued - passing the exam alone isn't sufficient grounds to market yourself as hand-certified.
Full certification also requires a 12-consecutive-month ACGME-accredited hand fellowship with a minimum of 48 clinical weeks, at least 15 months of active hand surgery practice post-training, a 15-consecutive-month case list submitted within the two years preceding application, an unrestricted medical license, full hospital operating privileges, and peer review from a Chief of Staff or Chief of Surgery plus two hand surgeons.

Key Takeaway
ABPS does not publish a study guide - there is no official prep resource. Structured practice questions and domain-mapped review, like what's available on the main HSE practice test platform, fill that gap deliberately.
FAQ
175 multiple-choice questions total, split into four blocks of approximately 44 questions each, with 60 minutes per block - roughly 4 hours of testing time plus an optional 15-minute tutorial and 15-minute break.
No. Scoring is based purely on total correct answers, so every question should be answered even if you're unsure - leaving items blank only costs you potential points.
You must repeat the entire 175-question exam; there is no option to retest only the domains you scored poorly on. Results remain admissible for five years, extendable by four more up to a nine-year ABMS limit.
Yes, as of 2025, candidates can sit for the exam immediately after completing a 12-month ACGME-accredited hand fellowship, prior to primary certification, provided a Preliminary Fellowship Program Director Recommendation unlocks the registration form.
Registration and application fees are $800 each, with a $160 late fee applicable to either if missed, a $520 withdrawal fee if you back out, and a separate $500 recertification fee plus a $410 Continuous Certification fee to keep the certificate active long-term.
