Radial head dislocations in children with below-elbow deficiencies
The Journal of Hand Surgery
|September 1, 1992
Summary
Two-thirds of children with below-elbow limb deficiencies, congenital or acquired, also have radial head dislocations. This condition typically does not require surgery or prosthetic adjustments.
Area of Science:
- Pediatric Orthopedics
- Congenital Limb Differences
- Upper Extremity Anomalies
Background:
- Below-elbow limb deficiencies, whether congenital or acquired, are associated with other musculoskeletal abnormalities.
- Radial head dislocation is a frequently observed concomitant condition in these patients.
Purpose of the Study:
- To investigate the incidence and characteristics of radial head dislocations in children with below-elbow deficiencies.
- To determine the implications of radial head dislocation for surgical management and prosthetic fitting.
Main Methods:
- Review of pediatric cases with below-elbow limb deficiencies.
- Analysis of the relationship between residual limb length and the direction of radial head dislocation.
- Evaluation of the need for surgical intervention or prosthetic modification for these dislocations.
Main Results:
- A high prevalence (two-thirds) of concomitant radial head dislocations was observed in children with below-elbow deficiencies.
- The direction of radial head dislocation was found to be significantly influenced by the length of the residual limb.
- Specific surgical treatment for the dislocation was rarely indicated, and prosthetic modifications were infrequently necessary.
Conclusions:
- Radial head dislocation is a common finding in children with below-elbow limb deficiencies.
- The management of radial head dislocation in this population is generally conservative, with low requirements for surgical or prosthetic intervention.

01:19Bones of the Upper Limb: Humerus
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...
01:15Bones 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.

01:09Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
