Fixing fractures near the top of the arm bone (the proximal humerus) has improved a lot over the past 20 years. Doctors often struggled with tricky breaks, so new tools like the variable angle 3.5mm PHMA locking plate came about to make things easier. This special plate is strong yet flexible, helping surgeons put broken pieces back together more precisely. It’s become a go-to choice for treating these tough fractures because it balances solid fixation with gentle care of surrounding tissues.
