Incision of retinaculum

The third compartment is opened completely in line with the EPL tendon in the extensor retinaculum.
When opening the tendon sheath, be careful not to cut the tendon.

The incision is extended proximally in line with the EPL tendon.

Mobilization of extensor pollicis longus tendon

The extensor pollicis longus tendon (EPL) is freed and a vessel loop is passed around it.

The tendon is pulled towards the radial side.

Subperiosteal elevation of 4th compartment

The fourth compartment is elevated subperiosteally, leaving the compartment itself intact. The intermediate column is now exposed.

The tendons of the 4th extensor compartment are held to the ulnar side.

If necessary, the tendons of the second extensor compartment are mobilized to the radial side.

The periosteum is incised on the dorsal side of the third metacarpal and the interosseous muscles elevated subperiostally if necessary.
