Ulnar Abutment Syndrome in the Athlete

Area of Science:

• Orthopedics
• Sports Medicine
• Biomechanics

Background:

• Ulnar abutment syndrome, or ulnocarpal impaction, is a common cause of ulnar-sided wrist pain in athletes.
• It involves excessive load transfer across the triangular fibrocartilage complex and ulnocarpal joints, leading to degenerative changes.
• This condition is often associated with static or dynamic ulnar positive variance.

Purpose of the Study:

• To review the presentation, biomechanics, and treatment options for ulnar abutment syndrome in athletes.
• To highlight the importance of tailoring treatment to individual athletes and their specific sporting demands.

Main Methods:

• Literature review focusing on ulnar abutment syndrome in athletic populations.
• Analysis of biomechanical factors contributing to ulnocarpal impaction.
• Evaluation of current and emerging surgical and non-surgical treatment strategies.

Main Results:

• Ulnar abutment syndrome is characterized by degenerative changes in the ulnocarpal joint and triangular fibrocartilage complex.
• Ulnar positive variance is a key factor contributing to the condition.
• Surgical interventions, such as metaphyseal closing wedge osteotomy, can effectively unload the ulnocarpal joint.

Conclusions:

• Ulnar abutment syndrome requires a personalized treatment approach for athletes.
• Addressing ulnar variance is crucial for successful management and unloading of the ulnocarpal joint.
• Further research into the biomechanics and long-term outcomes of various treatment options is warranted.
