Disectomy Technique for Posterolateral L4/5 disc 

Anatomy

L4/5 disc at level of facet joints

Interlaminar space is below disc

- have to take inferior aspect of superior lamina

Pedicle and transverse process at same level

Disc usually on one side

- hemilaminotomy

- no need to remove spinous process

- this preserves stability

Definition

Benign enlargement of the common digital branch

- usually 3rd webspace

Anatomy

Found at level of or just distal to MT heads

- deep to the deep transverse MT ligament

Epidemiology

1.  Buckley etal JBJS Am 2002

Prospective multi-centred RCT

- 309 displaced intra-articular fractures

- operative v non operative management

- 2 year follow up

Findings

- used patient orientated functional outcomes

- overall VAS and SF36 not significantly different between 2 groups

Improved Operative Outcome if

- not workers compensation

- women

- < 29
