CADAVERIC STUDY USE REFERENCE POINTS AS LANDMARK FOR LOCKING PLATE SYSTEM POSITION IN PROXIMAL HUMERAL FRACTURES
Main Article Content
Abstract
Objectives: The aim of our study was to determine the optimal plate plaCement using the first
and seCond PHILOS plate resemble by identifying the proximal portion of biCipital grooVe, the most prominent of the lesser tuberosity, and the upper border of peCtoralis major tendon as surgiCal landmarks.Methods: The study was Carried out by a Cross-seCtional on 30 shoulder of 15 CadaVeriC patients, at the Department of Anatomy, UniVersity of MediCine and PharmaCy at Ho Chi Minh City in 2020. Results: Using the proximal portion of biCipital grooVe, the most prominent of the lesser tuberosity as landmarks, distanCe from the margin of plate to the upper border of greater tuberosity when using 1st generation PHILOS plate is 7.84 ± 1.62 mm and 8.61
± 1.64 mm, respeCtiVely, and when using the 2nd generation PHILOS plate is 12.30 ± 3.26 mm and
13.50 ± 2.13 mm, respeCtiVely; distanCe from the CalCar sCrew to the inferolateral border of humeral head when using 1st generation PHILOS plate is 7.30
± 1.50 mm and 6.40 ± 1.66 mm, respeCtiVely, and when using the 2nd generation PHILOS plate is 4.81 ±
1.64 mm and 3.72 ± 1.46 mm, respeCtiVely. Conclusion: the proximal portion of biCipital grooVe, the most prominent of the lesser tuberosity, and the upper border of peCtoralis major tendon Can be used as landmark for proper position of 1st and 2nd generation PHILOS plate. The highest probability of CalCar sCrew in proper loCation when this distanCe is from 23mm to 25mm.
