Summary
Simultaneous dislocations of the proximal and distal interphalangeal joints in one finger are rare and can be missed. Careful examination and imaging are crucial to avoid complications like capsular contraction requiring surgery.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Radiology
Background:
- Simultaneous dislocations of the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints in a single finger are uncommon.
- Routine evaluation may overlook one of the dislocations due to their proximity.
Observation:
- In cases of suspected phalangeal joint dislocations, obtaining adequate pre- and post-reduction roentgenographic views is essential.
- Thorough examination of the affected joints is necessary to differentiate between capsular contraction and soft-tissue interposition.
Findings:
- Failure to diagnose simultaneous PIP and DIP joint dislocations can lead to missed injuries.
- Delayed recognition can result in capsular contraction, a complication that may necessitate surgical intervention.
Implications:
- Emphasizes the importance of meticulous diagnostic procedures in hand trauma.
- Highlights potential long-term complications arising from under-recognized joint dislocations.
- Underscores the need for surgical consideration when conservative management fails due to missed diagnoses.

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.

01:10Ankle 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,...
