What is the next step in evaluation? 1-MRI b/l tibiae; 2- Venous doppler US; 3-Non-invasive arterial vascular studies; 4- Comprtmnt pres msrmnt; 5-Bone scan

During strenuous exercise, muscle fibers can swell up to 20 times their resting size, leading to 20% increase in the muscle volume and weight. When the blood flow is insufficient to meet the requirements of the muscle, the patient experiences pain. Measuring the intracompartmental pressures at rest and post-exercise have been shown to be the best method of confirming the diagnosis of CECS, diagnostic criteria: 1) preexercise pressure = 15mm Hg, 2) a 1 minute postexercise pressure of =30 mm Hg, or 3) a 5 minute postexercise pressure = 20 mm Hg.Ans4

(GIRD), = posterior cuff & capsular contracture. Biomechanical studies -> humerus is translated in a posterosuperior direction during the cocking phase of throwing in the setting of a posterior capsular contracture, increased ER may be attributable to inc'd hum retroversion, while the IR deficit is caused by soft tissue adaptations.Ans1
