Early complications of operatively treated proximal humeral fractures

Abstract

Minimal information exists regarding early complications after operatively treated proximal humeral fractures. Of the 82 shoulders that hod osteosynthesis, 42 had a (nonmedical) complication, with 2 1 requiring further surgery. Of 42 shoulders with complications, 72 were related to incomplete reduction, 16 had loss of anatomic fracture fixation, 9 had delayed healing, 3 had an infection, 1 had rotator cuff failure, and 1 had loose bodies. Fixed-angle plates had lower rates of initial malpositioning and resultant malunion. Of the 22 shoulders requiring hemiarthroplasty, 14 had an early complication. Of these, 7 had complications relating to implant insertion or tuberosity malreduction at the index operation and 7 had problems with tuberosity healing. The rate of complications after operative treatment of proximal humeral fractures is high. All efforts at fracture fragment fixation with osteosynthesis and hemiarthroplasty should be directed at obtaining anatomic fracture fixation that resists displacement.
