Practice questions
- In a retrospective study of 117 carpal tunnel release procedures, how many patients underwent nerve conduction studies (NCS)?
- In the CTS study, what was the median time from initial orthopaedic consultation to surgery among patients who had NCS?
- The median time to surgery was 206 days with NCS and 73 days without NCS in a retrospective CTS cohort. Which interpretation is best supported?
- According to the CTS study authors, when may NCS be particularly useful before surgery?
- Which methods were reported for diagnosing the 31 CTS patients who did not undergo NCS?
- A patient has a clinically convincing presentation of CTS and is being considered for release. Which conclusion best reflects the supplied study?
- A systematic review of technologies for total elbow arthroplasty reported which combination of findings compared with conventional planning methods?
- Which technology was included in the systematic review of planning and intraoperative navigation for total elbow arthroplasty?
- Which set contains only technologies assessed for total elbow arthroplasty planning or navigation in the systematic review?
- What evidence gap did the TEA technology review identify despite improved implant positioning?
- The TEA systematic review included 16 articles, 89 patients, and 55 cadaver elbows. Which interpretation of these numbers is appropriate?
- A surgeon notes that a planning technology improves implant positioning in TEA. What is the most defensible statement about patient benefit based on the review?
- Teratoid Wilms tumor is characterized in the supplied systematic review by which defining morphological feature?
- Which histological components were among the frequently documented heterologous findings in teratoid Wilms tumor?
- Among 21 TWT patients with evaluable response to neoadjuvant chemotherapy, 17 had minimal response, poor or no response, or progressive disease. What percentage did the review report for this combined outcome?
- A learner concludes that every teratoid Wilms tumor is resistant to neoadjuvant chemotherapy because most evaluable cases had limited response. Which correction is best?
- What did the TWT review identify as central to management despite frequent limited response to neoadjuvant chemotherapy?
- How many unique patients with definite teratoid Wilms tumor were identified by the patient-level systematic review?
- The review reported that 35 of 42 TWT patients with evaluable disease status had no evidence of disease at last follow-up. Which interpretation is most appropriate?
- In the meningioma cohort, what was the primary endpoint?
- Which set of preoperative measures was evaluated in the study of non-skull-base meningioma resection?
- Which finding was reported as a risk factor for non-home discharge after non-skull-base meningioma resection?
- Which combination was reported to correlate with longer postoperative stay in the meningioma cohort?
- The reported Spearman correlation between tumor volume and postoperative length of stay was rs = 0.57. What does this result support?
- In the 120-patient non-skull-base meningioma cohort, what proportion was discharged home?
- A frail older patient with a large non-skull-base meningioma and substantial edema is being assessed for resection. Which inference best fits the supplied cohort study?
- Which statement correctly describes the design and population of the supplied meningioma outcomes study?
