Headless Compression and Twist-Off Screws
Surgical Technique
Osteotomy
A linear capsulotomy is then used to expose the
joint. The hypertrophic medial eminence on the 1
st
metatarsal head is then osteotomized (Figure 3).
Insert a 0.9 mm k-wire perpendicular into the center
of the first metatarsal head (Figure 3a).
A medially based long arm Chevron type osteotomy
is then created from medial to lateral. Remove
the k-wire. The capital fragment is then mobilized
and transposed laterally to correct the 1
st IMA and
impacted on the 1 st metatarsal shaft (Figure 3b).
