the medical or ‘orthopedic’ treatment of a fracture of the upper end of the humerus comprises:
an immobilization phase
4 weeks in general (see 6 for some cases)
– on abduction cushion concerning the potentially unstable fractures of the major tubercle (bulky fragment), this allows the relaxation of the supraspinous tendon.
– bend to the body in internal rotation (hand on the belly) for potentially unstable fractures of the minor tubercle, this allows relaxation of the subscapularis tendon.
