Abstract

A 75-year-old lady presents with a 4-year history of progressive shoulder pain. She has now developed pain at night and hence seeks medical attention. She feels her shoulder has also become weaker. Clinical examination reveals pseudoparalysis with an inability to actively elevate her arm above the shoulder level, although her passive movements are preserved. Clinical examination reveals wasting of the supraspinatus and infraspinatus fossa and an inability to get her arm into the “combing” position. Patte’s sign, drop arm sign and external rotation lag sign are positive.
