Bones of the Upper Limb: Radius

Bones 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.
The radius has a nail-shaped head, and a...

Area of Science:

Orthopedic surgery
Hand surgery
Congenital hand differences

Background:

Type IV radial polydactyly is a congenital hand difference characterized by a thumb with duplicated proximal and distal phalanges.
Accurate assessment is crucial for effective surgical planning and reconstruction.

Purpose of the Study:

To describe the assessment and surgical reconstruction of Type IV radial polydactyly.
To evaluate the outcomes and potential complications of surgical intervention.

Main Methods:

Surgical reconstruction involves excising the smaller, typically radial, thumb.
Restoration of thumb stability and alignment is achieved by addressing tendon insertions and joint orientation.

Main Results:

Surgical outcomes for Type IV radial polydactyly reconstruction are generally satisfying.
Complications are uncommon, but long-term issues like malalignment or instability may necessitate further surgery.

Conclusions:

Surgical reconstruction of Type IV radial polydactyly can yield good results.
Ongoing monitoring is important to address potential long-term thumb malalignment or instability.
