Scaphoid - Dorsolateral Approach
The Scaphoid – Dorsolateral Approach course will teach you:
To access the scaphoid bone using a dorsolateral approach. This is most commonly indicated for fracture assessment in conjunction with a subsequent reconstruction and fixation.
Special attention is paid to the following hazards you may encounter during the Scaphoid – Dorsolateral Approach:
- Dorsal carpal branch of radial nerve injury
- Extensor tendon injury by retractors
With the following tips you might perform the Scaphoid – Dorsolateral Approach even better:
- Anatomical variation of the dorsal superficial branch of the radial nerve
- Identification of the extensor tendons by extension of the thumb
- Exposure of the proximal third of the scaphoid by deviating the hand in an ulnar direction
- Radiocarpal joint closure
After studying the Scaphoid – Dorsolateral Approach course you are familiar with the most common complications:
- Avascular osteonecrosis
- Non- union
- Degenerative changes
- Dorsal superficial branch of radial nerve injury

Identify on the skin the radial styloid process, the anatomic snuff box and the 1st metacarpal by palpation.
Mark a S-shaped line on the skin, first curve ulnar then radial, starting from the styloid process of the radius, over the anatomic snuff box and ending over the base of the 1st metacarpal.
