Summary
Pain at the index finger metacarpal tubercle is a distinct condition. Steroid injections offer initial relief, while surgical excision provides lasting pain improvement for index finger pain.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Anatomy
Background:
- The index finger metacarpophalangeal joint is a common site of hand pain.
- Existing literature lacks specific identification of the dorsoradial tubercle as a pain source.
Purpose of the Study:
- To identify and describe the dorsoradial tubercle of the index finger metacarpal as a specific pain site.
- To investigate the efficacy of treatments for pain originating from this anatomical landmark.
Main Methods:
- Retrospective review of patients with pain at the dorsoradial index finger metacarpal tubercle.
- Initial management with corticosteroid injection, followed by surgical excision if conservative measures failed.
Main Results:
- 9 out of 10 patients received steroid injections; 5 had complete pain resolution initially.
- 4 patients experienced recurrence of pain, with 3 undergoing successful surgical excision.
- Surgical excision resulted in minimal discomfort and significant pain improvement.
Conclusions:
- The dorsoradial tubercle of the index finger metacarpal can be a distinct source of hand pain.
- Subacute radial collateral ligament injury is a potential cause of pain at this tubercle.
- Corticosteroid injection is a viable initial treatment, and surgical excision offers satisfactory long-term results.

01:17Muscles of the Forearm that Move the Hand and Fingers
1.5K
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...

01:09Bones of the Upper Limb: Radius
3.2K
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.

01:15Bones of the Upper Limb: Ulna
2.9K
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...

01:19Bones of the Upper Limb: Humerus
5.0K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:10Bones of the Lower Limb: Tibia and Fibula
5.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

01:16Muscles that Move the Forearm
2.4K
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...
