MSK II Exam 2 STUDY GUIDE QUESTIONS AND ANSWERS GRADED A 2024

main pain generator for general elbow conditions... soft tissue what are grades 1 and 2 mobilizations used for? pain relief types of traction progressions at the humeroulnar joint (2) HUJ extension HUJ flexion types of glides used at the humeroulnar joint (3) medial lateral lateral flexion ROM exam upon suspicion of elbow fx full extension of the elbow vs full ROM in the sagittal plane elbow has better sn/sp on ruling in fx what is the best imaging study for a complex elbow fx? CT or 3D reconstructed CT scan - CT scan is also best for small/ subtle fxs or etiologies w/i the elbow best exam study for chondral defects w/i the elbow ROM - if it is true cartilage defect you will have a consistency of the pattern (same pain at the same point of ROM in time) best imaging study for chondral defects w/i the elbow? (2) MRI and CTA are best - US; depends on location can help w/ plica typical elbow triad 1.) numb capsular pattern 2.) pain moves around and isn't consistent 3.) pseudo-locking best exam study for ulnar collateral ligament pathology? dynamic valgus stress test sn: 100% sp: 75% - not much of anything for the lateral collateral best imaging study for ulnar collateral ligament pathology? MRI is best for a full tear MRA (arthrogram) is best for a partial tear best imaging study for RCL/LUCL pathology? most imaging studies of ligaments involve MR or MRA, however; no studies for this pathology (RCL is rare) (LUCL is oblique and hard to image) best exam study for RCL/LUCL pathology Pivot shift test is best ("when used during pt. sedation vs when the pt. is alert") - Dr. D best imaging study for epicondylitis MRI (will give you more information whether it is an "itis" or "osis") US is good as well best imaging for ulnar nn neuropathy/cubital tunnel pathology? nerve conduction study + US is best best exam study for ulnar nn neuropathy/cubital tunnel pathology? combined pressure and flexion provocation sn: 98% sp: 95% why must we as PTs correlate exam findings w/ imaging for elbow pathologies? b/c there is a high incidence for FALSE positives in the elbow in asymptomatic population what do we particularly see w/ overhead athletes w/i the medial and lateral compartments of the elbow? medial: changes in the soft tissue lateral: accelerated degenerative changes practice guidelines for when to request an x-ray? - trauma - suspected physical abuse - metabolic disease - neoplasm - primary bone pathology - infection - arthropathies - pre/post operative - pain image views available for the elbow?
