Epidemiology

 

Most common tumor of hand

- female > male

- 2nd - 4th decade

 

Etiology 

 

Unknown 

 

Location

 

Dorsal

- 70 - 80%

- scapho-lunate ligament

 

Volar

10 - 20%

- scapho-lunate ligament / STT joint

 

Retinacular - along flexor sheaths, A1 / A2 pulley

Mucoid cyst - associated with DIPJ OA and osteophyte

 

Clinical

 

Most asymptomatic and fluctuate in size

Pathology

 

Cyst cavity lined by epithelium

Contents - viscous mucin / hyaluronic acid

Nonoperative management

 

Natural history

 

Dias et al J Hand Surg Eur 2007

- 60% (23/55) of dorsal ganglion resolved spontaneously

 

Dearden et al J Hand Surg Am 2023

- 157 ganglion in children < 18

- 60% resolved spontaneously 

 

Aspiration + cortisone injection

 

Gregoire et al Orthop Traumatol 2022

- 85 dorsal ganglions treated with aspiration + cortisone

- 73% recurrence at 3 years

- 43% of non injected 14 ganglion cyst resolved spontaneously by 3 years

 

Operative management

 

Concept

 

Excision of ganglion (open versus arthroscopic)

- find neck and dissect down to capsule

- excise capsular window

 

Dorsal scapho-lunate ligament ganglion

 

Open excision technique

 

Vumedi open excision dorsal ganglion video

 

Dorsal approach over 3/4 compartment / Lister's tubercle

- transverse incision

- open extensor retinaculum

- between 3rd and 2nd compartment

- excise cyst / neck / dorsal capsule

- dissect off the scapholunate ligament

- leave capsule open to avoid stiffness

 

Arthroscopic excision technique

Results

 

Open excision

 

Cluts et al Hand 2022

- 3 surgeons and open excision 628 ganglion

- recurrence rate dorsal: 4%

- recurrence more common in males and less experienced surgeons

 

Open versus arthroscopic excision

 

Kang et al J Hand Surg Am 2008

- RCT of 72 patients open v arthroscopic excision of dorsal wrist ganglion

- recurrence arthroscopic: 11% 

- recurrence open: 9% 

 

Crawford et al J Hand Surg Eur 2018

- systematic review of open v arthroscopic excision of dorsal wrist ganglion

- recurrence rate arthroscopic: 9%

- recurrence rate open: 20%

 

Volar STT ganglions

 

Open excision technique

 

Youtube open excision volar ganglion video

 

Volar approach

- between FRC and radial artery

- radial artery at risk

- radial artery variable location relative to cyst

- can use ultrasound to identify radial artery location

- remove cyst + stalk

- resect small capsular window

Results

 

Open

 

Cluts et al Hand 2022

- 3 surgeons and open excision 628 ganglion

- recurrence rate volar: 4%

- recurrence more common in males and less experienced surgeons

 

Arthroscopic

 

Fernandes et al Hand Surg 2014

- systematic review of arthroscopic excision of 232 volar hand ganglions

- recurrence rate 6%

- complication rate 7%

- 3 dorsal radial nerve injuries

- 2 partial median nerve injuries

- 2 radial artery injuries
