Headless Compression and Twist-Off Screws
Surgical Technique
Figure 1
The following surgical technique describes the use of
a Headless Compression Screw for a distal Chevron
osteotomy of the first metatarsal or various types of
osteotomies (Figure 1).
Incision
A 7 cm incision is centered over the dorsal aspect of
the first metatarsophalangeal joint, just medial and
parallel to the EHL tendon. The incision is carried
down to the subcutaneous tissues (Figure 2). Retract
the soft tissues carefully being certain to protect the
neurovascular bundle in the skin flap.
Lateral Release
If necessary, a standard lateral release is performed
through the same incision. This includes the release
of the adductor tendon and the fibular sesamoidal
ligament.
