Ludloff Osteotomy for Hallux Valgus

- Discussion:
    - oblique first metatarsal osteotomy that begins dorsal-proximal and continues plantar-distal;
    - osteotomy begins dorsally 1 mm distal to the metatarsocuneiform joint at a 30 deg angle;
    - most distal portion of plantar aspect of osteotomy is left temporarily intact; 
    - initial screw fixation:
         - a 3.5 screw is placed proximally, a right angles to the osteotomy, and is gently countersunk;
    - rotation of osteotomy:
         - distal aspect of osteotomy is completed;
         - proximal screw acts as an axis for rotation of the distal metatarsal over the proximal metatarsal;
         - rotation of osteotomy is completed, and first screw is fully tightened;
    - second screw:
         - second screw is inserted plantar and distal to the first screw;
         - consider a 2.7 mm screw; 
    - complications:
         - type of intrinsically unstable osteotomy if wt bearing distracts osteotomy making stability completely dependent on fixation devices until union occurs
