OBJECTIVE: It is common to get lost during a comminuted proximal humerus surgery, and the pectoralis major insertion is always a constant. Therefore, this study aimed to do a cadaveric study on the Filipino population to assess the distance from the pectoralis major tendon to the top of the humeral head (PMT) as a reference during proximal humerus surgery. METHODS: This study dissected the shoulders of cadavers. The distance from the pectoralis major tendon insertion to the top of the humeral head (PMT) was measured using a caliper. This PMT distance was also correlated to the cadaver's height and sex. RESULTS: This study dissected 110 shoulders (55 cadavers | 24 females, 31 males). The median PMT was 5.40 cm for males and 4.90 cm for females, with a combined value of 5.40 cm overall. There was a direct and moderate correlation between the PMT with overall height. Height and PMT of both the left and right shoulder were significantly longer among males compared to females. The study showed that for every centimeter increase in the height of males, there was a corresponding 0.02 cm increase in the PMT, adding the constant factor of 1.83. A corresponding 0.04 cm increase in the PMT for females added the constant factor of -0.81. CONCLUSION; The pectoralis major tendon insertion is a consistent landmark that can accurately restore humeral length when reconstructing complex proximal humerus fractures where landmarks are otherwise lost because of comminution.

Background: In the face of the COVID-19 pandemic and a country-wide lockdown, the University of the Philippines College of Medicine halted face-to-face teaching in exchange for online learning for its students. For the Learning Unit VI students, clinical rotations shifted to hybrid activities to continue learning activities while minimizing exposure risk. The Philippine General Hospital Department of Orthopedics introduced the following hybrid activities in its curriculum for Learning Unit VI students: 1) Online Lectures, 2) Online Departmental Conference, 3) Online Division Rounds, 4) Online SGDs, 5) Written Case, 6) Online Exams, 7) Preceptorship, Demo, Return Demo, and 8) Online OSCE. The department used a variety of platforms including synchronous sessions, asynchronous pre-recorded lectures, and face-to-face teaching, as appropriate. Objectives: The study compared the faculty and student course evaluations of activities in the hybrid ORTHO 251 course. Methodology: Faculty and students were asked to evaluate each activity according to the Course Evaluation By Students (CEBS), the standard questionnaire used by the college, to determine the overall rating of each activity as well as any differences between the two groups. Results: The hybrid activities conducted in the ORTHO 251 course were rated as good or excellent by the faculty and students, with differences in a few activities. Consultants rated online exams as being less effectively integrated and that there was inadequate time allotment for online SGDs, written cases, and online exams. Meanwhile, students rated all activities higher in terms of stimulating self-directed learning. Conclusion With good to excellent outcomes, this study found that it has at least satisfactorily matched the learning platform to the learning component. While knowledge may be taught via asynchronous recorded lectures or reading materials, attitude and thinking processes are better formed through synchronous discussion. Skills in medical education, including Orthopedics, are still best taught via face-to-face demoreturn demo. With this information, the department can investigate the causes of these differences and improve on the identified weaknesses.

Introduction: Rotator cuff tears are one of the common etiologies of shoulder pain. Rotator cuff repair is recommended for a patient who failed conservative treatment. Proper knowledge of the rotator cuff footprint is needed in restoring correct anatomy during the repair. The size of the footprint is important in determining the kind of repair. Objective: This study aimed to define the average measurements of the rotator cuff footprint on the humerus in Filipino cadavers. Methods: This is a descriptive, cross-sectional study of preserved human cadaver upper extremity specimens. We measured the length, width, and shape of the supraspinatus, infraspinatus, subscapularis, and teres minor. Results: We obtained 27 upper extremity specimens. The median age of the source cadavers was 50.5 years with the equal male-to-female distribution. The mean measurement of the supraspinatus is 22.92 mm in length and 10.17 mm in width. The shape of the supraspinatus was found to be trapezoidal. The infraspinatus length was found to be 17.20 mm and the width at 10.72 mm. Its shape was found to be trapezoidal. The teres minor length was measured at 15.15 mm and the width at 11.04 mm. The shape was mostly trapezoidal but some were triangular. Finally, the subscapularis length was 17.68 mm while the width was 11.26 mm. The shape was trapezoidal or comma-shaped. Conclusion The average measurement of the rotator cuff footprint was found to be smaller in our study than reported in terms of length and width. The footprint shape was similar to the studies reported.
