WEIL OSTEOTOMY OF LATERAL METATARISTS
It is a well-known metatarsal distal oblique osteotomy that provides longitudinal decompression but may also provide medial and lateral transverse displacement.
Weil’s osteotomy is very effective in the correction of claw toes. With this technique, the correction can be performed virtually without proximal interphalangeal arthroplasty or arthrodesis, with a simple manipulation of the toe or with a plantar release of this joint.
It is a section of the first metatarsal located behind the cartilage of the head, forming a V in the dorso-plantar direction.
The current trend in France is to practice a longer line for the plantar part.
The head is pushed in translation towards the second metatarsal and then fixed by one or two oblique screws.
The bone surplus is cut. This section is suitable for moderate and medium deformations.
His advantages :
The skin incision is short (25-35 mm).
It can be considered as minimally invasive.
OSTEOTOMY OF SCARF
This is a section of the bone that can be re-oriented to correct a deformity generally Tailor bunion or bunion. The evolution in the absence of treatment is the increase of the deformation with the appearance of a red tumefaction on the side of the foot (bursitis). There is no medical treatment for this deformity. Only fitting the boot can improve comfort.
The bone is cut in half in length. The two bone fragments are displaced to correct the axis of the metatarsal and remove the deformity. The bone fragments may or may not be fixed with 1 or 2 screws or spindle depending on the needs and operative findings.
The osteotomy of the fifth metatarsal is a frequent intervention, correcting the bunion, allowing to restore a normal function of the foot after a few months.
