Internal fixation of acetabular quadrilateral plate fractures in elderly patients: Could the fracture reduction quality affect their functional recovery?

Background: Osteoporotic acetabular fractures frequently involve the quadrilateral plate (QP), a flat and thin bone constituting the medial wall of the acetabulum. This study aims to assess the impact of the quality of osteoporotic QP fractures reduction on the patients' functional recovery, at 24 months follow-up.

Methods: Patients referring with osteoporotic QP fractures to our Level I trauma centre were prospectively recruited.

Reliability of forced internal rotation and active internal rotation to assess lateral instability of the biceps pulley.

Purpose: the aim of this study was to investigate the relationship between positive painful forced internal rotation (FIR) and lateral pulley instability in the presence of a pre-diagnosed posterosuperior cuff tear. The same investigation was conducted for painful active internal rotation (AIR).

Methods: a multicenter prospective study was conducted in a series of patients scheduled to undergo arthroscopic posterosuperior cuff repair.
