Three common clinical scenarios leading to wrist arthroscopy

3 Common Clinical Scenariosleading to

Wrist ArthroscopyNickolaos A. Darlis, MD, PhD

To access this presentation on the web:


I am here to convince you that

Clinical Exam + Plain X-rays=80% of the indications for wrist arthroscopy

#1. Radial-sided wrist pain

Radial-sided pain DD

Scaphoid fracture

SL lig. tear

Kienbock’s

AVN Scaphoid/ Preiser’s

CMC arthritis

Occult ganglion cyst

Metacarpal boss

Radiocarpal impingement

ScaphoLunate instability

Scapholunate ballottment test

Watson’s test Wrist flexion- finger extension maneuver

Anatomic snuffbox synovial irritation

Anatomic snuffbox= synovial irritation

Dorsal SL- lunate pain

Watson’s test

X-rays 1: True PA view

900 -900 position

X-rays 1: True PA view

• SL gap> 2-3mm (static instability)

• “Shortened” scaphoid

• Cortical ring sing

X-rays 2: Pronated grip view

1. Dynamic SL diastasis

2. Ulnocarpal Impingement

3. Ulnar Variance measurements

X-rays 2: Pronated grip view

NEUTRAL GRIP

Dynamic SL instability

X-rays 3: Comparative

Radiocarpal Arthroscopy• Always Probe the SL lig.

1. Central TFCC lesions

• Poorly vascularized- healing potential minimal

• Arthroscopic debridement up to 2/3 of articular disc

Arthroscopic TFCC debridement using radiofrequency probes Darlis NA & Sotereanos DG, JHS(B)2005



• Often degenerative and associated with ulnocarpal impaction syndrome

• Ulnar recession procedure to prevent symptom recurrence

Ulnocarpal Impaction Syndrome

Clinical features:

• Ulnar sided wrist pain

• Associated degenerative changes:

– Ulnar side of the lunate

– Radial side of the ulnar dome

– TFCC central tear

– Triquetrum- LunoTriquetrum lig.

• Usually positive or neutral ulnar variance

Arthroscopic Wafer procedure

• Preferred when modest shortening needed

Open Ulna Recession Procedures• Several options…

Open Ulna Recession Procedures

Another approach: Keep it simple…

• Step-Cut Ulnar Shortening Osteotomy

Darlis& Sotereanos JHS(A), 2005

2. Peripheral (ulnar) TFCC tears

• Well vascularized

• Repairable

3. Distal Radius Fracture

• Consider in young, high demand patients

• Currently indicated in selected injuries:

– Radial styloid Fx

– Die Punch Fx

– Three & Four part Fx

– DRUJ instability or interosseous lig tear

• No metaphyseal comminution
