Definition A triceps tendon rupture occurs when the tendon tears or avulses from its insertion point on the olecranon, resulting in difficulty or inability to extend the elbow against gravity or resistance. Complete ruptures involving all three heads of the triceps tendon (long, lateral, and medial) typically require surgical intervention.
Definition Medial epicondylitis, often referred to as golfer’s elbow, involves tendinosis at the origin of the flexor-pronator mass. Despite its name, this condition is more commonly associated with racquet sports and manual labor. Anatomy The common flexor-pronator origin is located primarily on the anterior aspect of the medial epicondyle. It

Definition Lateral epicondylitis, commonly known as tennis elbow, involves tendinosis at the origin of the common wrist extensors. A more accurate term is lateral elbow tendinopathy, reflecting the condition’s degenerative nature. Anatomy The common extensor origin is located on the lateral epicondyle of the humerus. This origin includes the extensor

Definition Distal radioulnar joint (DRUJ) instability can be acute or chronic, unidirectional (volar or dorsal) or bidirectional, and isolated or associated with other injuries. Clinically significant instability is often identified by increased anteroposterior translation of the DRUJ with passive manipulation compared to the normal side. DRUJ dislocation or instability is
Definition The Triangular Fibrocartilage Complex (TFCC) is a crucial structure on the ulnar side of the wrist with several important roles: Extending the gliding surface of the radiocarpal joint Cushioning and stabilizing the ulnar carpus Stabilizing the distal radioulnar joint (DRUJ) Injuries to the TFCC can cause ulnar-sided wrist pain,

Definition An Essex-Lopresti injury, or longitudinal radioulnar dissociation (LRUD), occurs when a violent compressive load to the wrist results in a triad of injuries: disruption of the distal radioulnar joint (DRUJ), tear of the interosseous ligament complex (IOLC), and fracture of the radial head. Anatomy Pathogenesis Natural History Patient History

What is Ulnar Collateral Ligament (UCL) Reconstruction? UCL reconstruction is a surgical procedure to repair the ulnar collateral ligament, a key stabiliser on the inner side of the elbow. This ligament is crucial for elbow stability, particularly in athletes who perform overhead motions. The surgery primarily focuses on reconstructing the

What is Lateral Collateral Ligament (LCL) Reconstruction? Lateral collateral ligament (LCL) reconstruction is a surgical procedure aimed at repairing or reconstructing the LCL complex of the elbow. This ligament is crucial for maintaining elbow stability, particularly in preventing posterolateral rotatory instability (PLRI). LCL injuries often occur after significant elbow trauma,

What are Metacarpal Fractures? Metacarpal fractures refer to breaks in the bones of the hand that form the base of the fingers. These fractures can occur at the base, shaft, neck, or head of the metacarpals, leading to issues like shortening, rotation, or angulation of the bone. Since the metacarpals
What are Radial Head and Neck Fractures? Radial head and neck fractures are the most common type of elbow fractures in adults, accounting for 33% of all elbow fractures. These fractures can happen on their own or alongside other bone, cartilage, or ligament injuries. Treatment aims to restore motion and
What Are Capitellum Fractures? Capitellum fractures are rare, making up less than 1% of all elbow fractures. These fractures often occur along with radial head fractures and elbow dislocations. The capitellum is the rounded part of the elbow joint where the humerus (upper arm bone) meets the radius (forearm bone).

What is Elbow Replacement? Elbow replacement surgery involves replacing damaged parts of the elbow joint with artificial components. This surgery is typically considered for older adults who have severe elbow fractures that cannot be repaired with other methods. Why Consider Elbow Replacement? Most severe elbow fractures involve not just broken
