Fracture4
  • INTRODUCTION: There is no widely accepted standard for the classification and treatment of traumatic acromion/scapular spine fracture nonunion due to the scarcity of this condition and the confusion of terminology. (bvsalud.org)

  • For example, landing on an outstretched hand can result in a distal radius fracture (wrist fracture) or a scaphoid fracture. (coloradoinjurylaw.com)
Resection1

Humerus2
  • This narrowness is caused when the arm is being raised to shoulder height and the gap between the anterior edge of the acromion and the head of the humerus narrows. (klinik-am-ring.de)
  • During GH flexion or abduction, note excessive movement of head of humerus superiorly against acromion. (thestudentphysicaltherapist.com)
