49 stepping, lunging, and squatting. FMS proficiency has been associated with injury risk as well as in-season performance level. Sex differences in FMS scores exist in high school athletes with males scoring higher in the trunk stability push-up (TSPU) test. Differences have not been investigated in collegiate athletes. Results may aid sports medicine professionals in implementing injury prevention strategies. Methods. 275 NCAA Division II intercollegiate athletes (18-27 years; males, n=118; females, n=157) representing 15 teams were FMS assessed during their 2017-2018 pre-participation examinations using standardized procedures. Pearson Chi-square analyses were conducted to examine potential differences in the frequency of “1s” on the 7 tests between sexes, p<0.05. Results. Significant differences were found in 4/7 tests. Males showed greater dysfunction in the Shoulder Mobility (χ 2 = 10.821, p=0.001) and the Active Straight Leg Raise (χ 2 =4.034, p=0.036). Females showed greater dysfunction in the Hurdle Step (χ 2 =4.610, p=0.033) and Trunk Stability Push-up (χ 2 =84.347, p<0.001) Conclusion. Significant differences exist in movement pattern dysfunction between the sexes in collegiate athletes. Males had more scores of “1” in tests requiring mobility while females had more in tests requiring stability. Further research should be done to determine the causality of these differences. Grants.

Tibial tubercle fractures are rare, with one bilateral tubercle fracture reported among 21 case reports. Case presentation. A 14-year old Latino male arrived from a trampoline park with bilateral knee pain after landing with his knees in flexion. Physical exam demonstrated an overweight adolescent male with marked swelling and tenderness of his knees, unable to tolerate passive range of motion from a flexed position. The compartments remained soft, with sensation and pulses intact. Orthopedics emergently admitted the patient to the operating room where closed reduction under fluoroscopy was performed. The patient returned to the OR for open reduction and internal fixation to optimize approximation and was discharged a few days later. Deviation From the Expected. This is the first reported bilateral tibial tuberosity fracture that extends to the posterior cortex. Discussion. A simple avulsion fracture of the tibial tuberosity represents less than 1% of pediatric fractures, with only 21 bilateral fractures reported in published case reports. The injury is most common in males age 12-15 and occur at the ossification center. Treatment generally requires open reduction and internal fixation. Outcomes are good with frequent return to full activity. Given the marked swelling ED management must be focused on compartment syndrome. Conclusion. Tibial tubercle fractures are rare, with this case representing the first bilateral tubercle fracture with extension to the posterior cortex being reported in the literature. The diagnosis is imperative to ensure definitive treatment, optimal range of motion, and reduction of the fracture at the growth plate.

Patel College of Osteopathic Medicine, Nova Southeastern University Andrea Alvarez, Dr. Kiran C. Patel College of Osteopathic Medicine, Nova Southeastern University Harvey N. Mayrovitz, Ph.D., Professor, College of Medical Sciences, Nova Southeastern University Objective. This study was developed to obtain tissue dielectric constant (TDC) reference values in healthy individuals as a first step to further aid in the early detection of lower extremity edema due to congestive heart failure. Background. In the US about 550,000 new cases of CHF occur per year often with lower extremity edema. Once edema is visually observed the causative process is usually well established. However, there is no method that can conveniently detect the early and potentially insidious changes in fluid content of these regions. Methods. For this study skin tissue dielectric constant (TDC) was measured at 300MHz as a direct index of skin tissue water at arm, hand, lower leg and foot bilaterally in self-reported healthy persons of various ages. Parameter indicators were the ratio of the lower extremity to upper extremity TDC value. These included foot dorsum/forearm (FF), foot dorsum/hand FH), medial leg/hand (LH) and medial leg/forearm (LF). Results. A total of 44 subjects encompassing
