Gross Anatomy of the Elbow Capsule: A Cadaveric Study

PurposeThe elbow is an inherently stable joint because of its bony articulation and surrounding capsuloligamentous structures. Anatomic and biomechanical studies have focused on the medial and lateral collateral ligamentous contributions to stability. In 1918, Gray provided a qualitative description of the elbow capsule and its fibers. Our study was performed to detail the gross anatomy of the elbow capsule.MethodsWe evaluated the elbow capsule of 6 paired, fresh-frozen cadaveric specimens to detail gross capsular anatomy.ResultsWe identified 3 distinct bands within the anterior capsule and 3 distinct bands within the posterior capsule.ConclusionsFurther study is needed to delineate the functional meaning of these anatomic findings.Clinical relevanceGreater understanding of elbow capsule gross anatomy may lead to improved understanding of acute and chronic elbow pathoanatomy and treatment modalities.
