Challenging elbow deformities like fishtail deformity can arise from distal humerus fractures. These may result from suboptimal fracture reduction and can lead to permanent loss of motion.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Upper Extremity Surgery

Background:

  • Distal humerus fractures can lead to challenging deformities including nonunion, cubitus varus/valgus, and fishtail deformity.
  • While closed reduction is common for supracondylar humerus fractures, suboptimal outcomes can result in significant long-term issues.
  • Fishtail deformity, a consequence of avascular necrosis of the trochlea, presents unique challenges due to its potential irreversibility.

Purpose of the Study:

  • To discuss the challenging upper extremity deformities that can arise from distal humerus fractures.
  • To highlight the development and implications of fishtail deformity following distal humerus fractures.
  • To review the limitations of traditional treatments for these complex deformities.

Main Methods:

Related Experiment Videos

  • Review of clinical presentations and outcomes associated with distal humerus fractures.
  • Discussion of the pathophysiology leading to specific deformities such as fishtail deformity.
  • Analysis of treatment options and their efficacy for complex elbow deformities.

Main Results:

  • Suboptimal reduction or loss of reduction in distal humerus fractures can lead to nonunion, cubitus varus, cubitus valgus, and fishtail deformity.
  • Fishtail deformity, resulting from avascular necrosis of the trochlea, is a severe complication that may not be correctable with standard osteotomy.
  • While flexion contractures can be managed, a bony block from fishtail deformity may result in permanent loss of elbow motion.

Conclusions:

  • Fishtail deformity is a serious, potentially irreversible complication of distal humerus fractures, often leading to permanent motion loss.
  • Early and accurate reduction of distal humerus fractures is crucial to prevent the development of these challenging deformities.
  • Management of established fishtail deformity is limited, emphasizing the importance of preventative strategies.
