TEOT Ortopedia common mistakes
TEOT Ortopedia · Understand the traps and how to avoid them.
In a multiple-choice question about a limb injury, the candidate selects the diagnosis that matches the most striking finding (for example, a fixed, internally rotated leg) without first checking whether the mechanism and the neurovascular findings are consistent with that diagnosis.
Under time pressure, candidates anchor on the single most memorable sign and stop gathering the rest of the clinical picture, so they commit to a diagnosis before reading the whole stem.
What to do instead
Before looking at the answer choices, write down the mechanism, the key positive findings, and the key negative findings. Then eliminate any option that contradicts one of the negatives. Only then choose among the remaining options.
The candidate evaluates a suspected compartment syndrome by relying on the presence or absence of pain and on the distal pulses, and treats a palpable pulse as evidence against compartment syndrome.
Textbook teaching emphasizes the classic signs, but candidates forget that pulses and capillary refill can remain normal because compartment pressure damages muscle and nerve before it compromises the major vessels. Pain out of proportion is the earliest sign, and its absence does not exclude the diagnosis.
What to do instead
Memorize the hierarchy: pain out of proportion and pain on passive stretch come first, followed by paresthesia, then pallor and pulselessness late. When the clinical picture is uncertain, measure compartment pressure and act on the measured value rather than on the pulse.
The candidate interprets an ankle or knee radiograph in isolation, without applying a validated decision rule and without correlating the image with the specific point of tenderness, so a subtle fracture or a syndesmotic injury is missed.
Candidates want to reach an answer quickly and treat imaging as a shortcut. They also tend to read the image globally instead of systematically tracing the cortical lines and checking the joint spaces.
What to do instead
Use a fixed reading routine: trace every cortex, check each joint space, and compare the side that hurts with the other side when available. Apply the Ottawa rules explicitly in the stem, and correlate each imaging finding with the tenderness the stem describes.
In a pediatric case, the candidate applies adult criteria for a limp, a fracture, or a joint effusion, and therefore misses a diagnosis that depends on the child's age (developmental dysplasia of the hip, transient synovitis versus septic arthritis, a physeal injury, or a non-accidental injury).
Candidates overlearn adult patterns and do not automatically re-anchor on the age-specific differential. Growth plates also make pediatric radiographs harder to read, so candidates avoid committing to an interpretation.
What to do instead
For every pediatric stem, first state the age band and the corresponding differential list. Then apply the pediatric-specific decision tool (for example, the Kocher criteria for septic arthritis of the hip) and explicitly check for physeal involvement before deciding on a fracture pattern.
The candidate confuses the classification systems that share similar names, such as the Salter-Harris types, the Gustilo-Anderson grades, or the Garden and Pauwels classifications of femoral neck fractures, and picks a grade that does not match the described wound or displacement.
These systems are memorized as lists of numbers rather than as decisions about management, so under exam pressure the candidate retrieves the wrong list or shifts one grade up or down.
What to do instead
For each classification, memorize the management consequence attached to each grade (for example, which Gustilo grade mandates immediate debridement and which fracture pattern changes fixation). Reconstruct the grade from the consequence rather than from the number.
In an adult hip or knee case, the candidate recommends arthroplasty without first checking whether the patient's age, functional demand, bone stock, or infection status makes arthroplasty inappropriate, and without considering the non-operative or joint-preserving alternatives.
Candidates associate degenerative joint disease directly with prosthesis and skip the step of weighing indications, contraindications, and the sequence of treatment options.
What to do instead
Before choosing arthroplasty, run a checklist: age and activity level, failure of conservative treatment, bone quality, infection status, and whether an osteotomy or arthrodesis is a better option. State which criterion in the stem drives the decision.
The candidate manages a suspected bone or soft-tissue tumor by planning an immediate biopsy or excision in a non-specialist setting, without first obtaining staging imaging and without referring the patient to a reference center.
Candidates treat tumors like other surgical problems and prioritize speed over the sequence of staging, which can compromise limb salvage and survival.
What to do instead
Memorize the sequence: history and examination, then plain radiograph, then staging imaging (MRI of the whole compartment and chest imaging), then referral to a reference center, and only then biopsy, which should be performed at the center that will carry out the definitive surgery.
The candidate treats a suspected prosthetic joint infection or an osteomyelitis as a single decision (give antibiotics) and omits the steps of obtaining cultures before antibiotics, assessing the implant, and choosing between debridement with implant retention and a staged exchange.
Candidates compress a multi-step algorithm into one action, and they forget that antibiotics given before sampling reduce culture yield and change management.
What to do instead
For every infection stem, write the algorithm in order: obtain samples for culture first, then start empirical antibiotics, then decide on the surgical strategy according to the duration of symptoms, the stability of the implant, and the condition of the soft tissues.
The candidate answers a hand or wrist question using general orthopedic principles and ignores the specific anatomy and functional priorities of the hand, such as tendon zones, nerve territories, and the need for early protected mobilization.
The hand is treated as a small version of a long bone, so candidates apply generic fracture and wound rules and overlook the flexor tendon zones and the sensory territories that determine the answer.
What to do instead
Revise the hand as a separate system: draw the flexor tendon zones and the nerve sensory territories from memory, and for each injury state which structure is at risk and what rehabilitation sequence follows repair.
The candidate answers a sports medicine or rehabilitation question by recommending surgery or complete rest when the evidence favors a graded loading program, or the reverse, and does not distinguish an acute injury from an overuse injury.
Candidates conflate the severity of the imaging finding with the need for surgery, and they do not systematically classify the injury as acute or overuse before choosing the management.
What to do instead
For each sports case, first classify the injury as acute or overuse and grade its severity. Then match the treatment to the grade, favoring progressive loading and return-to-play criteria over blanket rest or early surgery, and state the criterion that would change the decision.
