Iran Orthopedic Surgery Board Exam common mistakes
Iran Orthopedic Surgery Board Exam · Understand the traps and how to avoid them.
On damage-control and polytrauma stems, committing to definitive internal fixation (e.g., an intramedullary nail or plate) in the same sitting as initial resuscitation, rather than staging with temporary external fixation and physiologic optimization.
Candidates pattern-match the fracture pattern to a definitive fixation technique and answer the 'best operation' question as if the patient were physiologically stable, ignoring the lethal triad and the damage-control decision tree that the stem is actually testing.
What to do instead
Before choosing an implant, explicitly state the patient's physiologic status (lactate, base deficit, temperature, coagulopathy, ISS) and ask whether the patient is 'stable, borderline, unstable, or in extremis.' For borderline/unstable patients, select staged damage-control fixation and name the trigger for conversion to definitive care.
Describing a nerve or vascular structure by name only (e.g., 'the axillary nerve') without stating its origin, course relative to a surgical landmark, and the specific injury or surgical approach that endangers it.
Anatomy is memorized as isolated labels rather than as spatial relationships, so candidates cannot transfer knowledge to the 'which structure is at risk during this approach' or 'which deficit localizes the lesion' format used on the exam.
What to do instead
Study each structure as a triad: origin/root value, course relative to named landmarks (e.g., surgical neck of humerus, quadrangular space), and the clinical/surgical consequence of injury. Practice reverse questions: given a deficit, name the nerve, level, and likely mechanism.
Selecting an arthroplasty option or bearing couple without matching it to the patient's age, activity level, bone stock, and expected survivorship, and without stating the revision implications of that choice.
Candidates anchor on the 'textbook' implant for a diagnosis (e.g., THA for displaced femoral neck fracture) and ignore modifiers in the stem such as young age, high demand, prior surgery, or poor bone quality that should shift the answer.
What to do instead
For every arthroplasty question, list the patient factors first (age, demand, BMI, bone stock, infection risk, life expectancy), then the implant/bearing options, then the survivorship and revision burden of each. Choose the option that best matches the factor profile, not the most familiar implant.
On spine stems, recommending surgery or a specific fusion construct without first classifying the pathology (e.g., degenerative vs. deformity vs. infection vs. tumor) and without stating the neurologic and stability indications that justify operative versus nonoperative care.
Spine questions are answered by pattern recognition of a diagnosis rather than by a structured algorithm of neurologic status, stability, and deformity, so candidates miss the stems where the correct answer is nonoperative or where the construct must address a specific deformity.
What to do instead
Use a fixed sequence for every spine stem: neurologic examination and red flags, stability assessment, deformity/alignment parameters, infection or tumor workup, then operative versus nonoperative decision, then construct choice. State which step drives the answer.
Treating a sports medicine or arthroscopy question as 'which operation is best' without first establishing the diagnosis through history, examination maneuvers, and imaging, and without considering nonoperative rehabilitation as a legitimate answer.
Candidates equate sports medicine with surgical procedures and skip the diagnostic reasoning step, so they miss stems where the correct answer is conservative management, a specific physical test, or a return-to-sport criterion.
What to do instead
For each sports stem, write the differential, the single best examination maneuver, and the imaging of choice before considering treatment. Then compare nonoperative and operative options against the patient's sport, level, and expectations, and state return-to-play criteria.
In pediatric orthopedics, applying adult fracture or deformity principles without accounting for physeal anatomy, growth remaining, remodeling potential, and the specific classification system (e.g., Salter-Harris, Gartland, Pavlik indications).
Adult-trained reasoning is overgeneralized to children, and candidates do not consistently identify the physis, the growth plate's contribution to remodeling, or the age-dependent treatment thresholds that the stem is testing.
What to do instead
For every pediatric stem, first state the patient's age and growth remaining, then classify the injury or deformity with the pediatric-specific system, then apply age-specific treatment thresholds. Explicitly discuss physeal risk and remodeling before choosing an intervention.
In hand and microsurgery questions, describing a tendon, nerve, or vascular repair in general terms without specifying zone, timing, technique, and rehabilitation protocol, and without recognizing which injuries require urgent versus elective management.
Candidates learn hand surgery as a list of named injuries rather than as zone-based and time-sensitive decision-making, so they cannot answer questions about flexor tendon zones, nerve gap management, or replantation indications.
What to do instead
Organize hand knowledge by zone and by urgency. For each structure, state the zone-based repair technique, the timing window, the rehabilitation implications, and the criteria for replantation or urgent exploration. Practice stems that ask 'what is the next step' rather than 'what is the diagnosis.'
On foot and ankle stems, choosing a procedure or weight-bearing status without addressing the deformity correction, the soft-tissue envelope, and the patient's comorbidity (diabetes, neuropathy, vascular status) that determine complication risk.
Candidates focus on the bony diagnosis and implant and neglect the soft-tissue and systemic factors that dominate foot and ankle decision-making, especially in diabetic and neuropathic patients.
What to do instead
For every foot and ankle question, assess the soft-tissue envelope, vascular and neurologic status, and deformity correctability before selecting treatment. State weight-bearing and immobilization plans explicitly, and name the complication most likely if the soft tissues are not respected.
On musculoskeletal oncology and metabolic bone disease stems, proceeding to biopsy or excision without first staging the lesion and without confirming whether the lesion is benign, and failing to recognize when referral to a tumor center is the correct answer.
Candidates treat oncology as 'diagnose and resect' and skip the staging, imaging algorithm, and referral thresholds, which is exactly the behavior the exam is designed to detect as unsafe.
What to do instead
Use a fixed oncology sequence: history and imaging (plain film first), determine benign versus aggressive versus malignant, stage if malignant, then decide biopsy and referral. For metabolic bone disease, confirm the biochemical diagnosis before treatment. When in doubt, the answer is referral to a specialist center before biopsy.
On infection and perioperative care stems, answering with an antibiotic or a single intervention without addressing source control, culture-directed therapy, and the host and implant factors that determine cure, and without recognizing when implant retention versus removal is indicated.
Candidates reduce infection questions to 'which antibiotic' and neglect the surgical and host factors that the stem is actually testing, leading to answers that would fail clinically even if the drug name is correct.
What to do instead
For every infection stem, state the source-control step (debridement, implant retention/removal/exchange), the culture and sensitivity strategy, the antibiotic duration and route, and the host factors affecting cure. Answer in that order before naming a drug.
