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 short...

Ankle Joint

Ankle 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...

Summary

This summary is machine-generated.

Percutaneous interlocking screws for medial column nails in Charcot foot reconstruction pose risks to nearby nerves and tendons. Surgeons must consider these anatomical risks during the procedure.

Area of Science:

Orthopedic Surgery
Anatomy
Biomedical Engineering

Background:

Medial column nails offer strong fixation for Charcot's neuroarthropathy reconstruction.
Percutaneous screw placement may risk injury to surrounding soft tissues.

Purpose of the Study:

To identify anatomical structures at risk during medial column nail interlocking screw placement.
To inform surgical technique and minimize iatrogenic injury.

Main Methods:

Ten cadaveric limbs underwent medial column nail insertion.
Kirschner wires simulated interlocking screws at proximal, middle, and distal locations.
Distances from wires to anatomical structures were measured and risk levels assigned.

Main Results:

Proximally, deltoid ligament, posterior tibial tendon, and saphenous vein were at risk.
The medial dorsal cutaneous nerve and medial marginal vein were at risk at the middle screw.
The medial dorsal cutaneous nerve was at high risk at the distal screw.

Conclusions:

Percutaneous interlocking screws for medial column nails present significant risks to neurovascular and musculotendinous structures.
Surgeons must be aware of anatomical relationships to mitigate injury during Charcot foot reconstruction.
