Proximal Humerus Fracture — Non-Operative

Dr. Michael C. Fu MD (Hospital for Special Surgery) · Michael C. Fu, MD, MHS

Weight-Bearing

NWB (arm) initially; progressive loading after fracture healing confirmed

Key Restrictions

Unstable: 4 wks full immobilization; Stable: 2-4 wks; no active motion until cleared; pain <3/10 at all times; no sensation of motion at fracture site

Timeline & Phases

Unstable: Phase I (4-8 wks, sling + passive ROM to 140 flex/40 ER) -> Phase II (8-12 wks, full PROM, wean sling) -> Phase III (12+ wks, AROM + strengthening). Stable: Phase I (2-4 wks) then aligns with unstable phases.

Notes

Distinguishes stable vs unstable fractures with separate timelines; radiographic clearance required to progress each phase
