This study mapped scapula bone thickness to find the best spots for internal fixation. The glenoid fossa is thickest, followed by the lateral border and spine, ideal for fracture repair.

Area of Science:

  • Orthopedic surgery
  • Anatomy
  • Biomechanics

Background:

  • Scapula fractures can be complex to treat.
  • Optimal internal fixation requires understanding bone thickness for screw purchase.

Purpose of the Study:

  • To measure and map scapula osseous thickness.
  • To identify optimal anatomical locations for internal fixation of scapula fractures.

Main Methods:

  • Utilized 18 cadaveric scapulae (9 pairs).
  • Established standardized measurement lines based on anatomical landmarks.
  • Measured bone thickness at specific intervals using 2-mm drill holes and a depth gauge.

Main Results:

  • Mean osseous thickness: Glenoid fossa (25 mm), lateral scapular border (9.7 mm), scapula spine (8.3 mm), central scapula body (3.0 mm).

  • Significant variation in thickness across different scapular regions.

    • Conclusions:

    • The lateral border, lateral base of the scapula spine, and the scapula spine itself are recommended for internal fixation.
    • Optimal screw purchase and fixation strength can be achieved by targeting these thicker regions.
