Scapula: fracture repair

Introduction

  • Supraglenoid tubercle and transverse fractures of the neck and body of the scapula can be treated by surgical methods in selected cases.

Uses

Advantages

  • Fragment resection:
    • Eliminates pain associated with movement at fracture site.
    • Reduce risk of osteoarthritis due to joint incongruity.
    • Fibrous reattachment of biceps brachii tendon may occur following removal of supraglenoid tubercle fragment, restoring tendon's role in shoulder extension.
  • Fracture reduction and internal fixation:
    • Realignment of articular surface.
    • Partial or complete tenotomy of biceps brachii tendon reduces post-operative tension on the fracture site.

Disadvantages

  • Same as scapula: fractures   Scapula: fracture  .
  • Resection of tubercle: disruption of joint surfaces with loss of part of glenoid cavity.
  • Internal fixation:
    • Strong distractive forces by biceps muscle may decrease stability of repair.
    • Large animals (>400 kg) are not good candidates.
    • Poor screw-holding ability of scapula.
    • Difficult to achieve good anatomic reduction.

Prognosis

  • Supraglenoid tubercle fractures: fair, provided good anatomic alignment of articular surface.
  • Transverse fractures of the neck/body: fair in young horses; guarded in adults.
  • Depends on degree of articular damage, and duration of prior nerve paralysis - maybe prolonged but eventual recovery of recovery of supraspinatus and infraspinatus muscle mass.
