Summary
Extensor mechanism injuries in athletes require prompt repair. Centralizing the extensor tendon and repairing the sagittal band allows athletes to return to sport with full motion.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Hand Surgery
Background:
- Extensor mechanism injuries in the hand can significantly impact a professional athlete's career.
- Metacarpophalangeal (MCP) joint injuries, specifically to the extensor mechanism, require precise surgical intervention.
Purpose of the Study:
- To evaluate the efficacy of extensor tendon centralization and sagittal band repair for MCP joint extensor mechanism injuries in professional athletes.
- To determine the functional outcomes and return-to-sport rates following this surgical technique.
Main Methods:
- Retrospective review of 8 professional athletes undergoing 11 MCP joint extensor mechanism repairs.
- Surgical technique involved extensor tendon centralization and sagittal band repair; capsular repair was not performed.
- Success criteria included full range of motion, return to professional sport, and no further surgery.
Main Results:
- All 8 athletes regained full MCP joint range of motion.
- All athletes returned to professional sports within an average of 5 months post-surgery.
- No additional surgical interventions were required for any of the athletes.
Conclusions:
- Extensor tendon centralization and sagittal band repair is a highly effective treatment for MCP joint extensor mechanism injuries in athletes.
- This technique allows for successful return to high-level sports participation without the need for capsular repair.

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:16Muscles that Move the Forearm
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:16Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
