Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of Chevron osteotomy devices.
Background technology
Intoe is one of most common deformity of ankle and foot, epidemiology statistics incidence about 28.4% (Fakoor M,
Sarafan N, Mohammadhoseini P, et al. Comparison of clinical outcomes of scarf
and chevron osteotomies and the McBride procedure in the treatment of hallux
valgus deformity. Arch Bone Jt Surg . 2014;2(1):31-36).Hallux valgus often can be with pain
Bitterly, patient's wear shoes and beauty are influenced, it is serious to form ulcer or infection.Hallux valgus operative treatment is curative for effect, at present
The intoe corrective procedure mode of report is orthopedic orthopedic more than 100 kind to bone from soft tissue, but most common orthopaedy formula
Mainly Chevron osteotomies and Scarf osteotomies（Iselin LD, Munt J, Symeonidis PD, et al.
Operative management of common forefoot deformities: a representative survey
of Australian orthopaedic surgeons. Foot Ankle Spec . 2012;5(3):188-194.）.Ginseng
See that Fig. 1, black line are osteotomy line, Chevron osteotomies are first metatarsal bone distal end " V " type osteotomies, and osteotomy is with the obvious advantage：1. cutting
Mouth is small；2. osteotomy, in the cancellous bone area osteotomy of metatarsal incidence, knitting is fast；3. one piece of screw stability maintenance is good；4. in art
Correction angle is easy to measure, and prevents undercorrection or excessively orthopedic.According to preoperative measurement, about per outer shifting 1mm in art, correct outside thumb
Turn over 1 ° of angle.
But the problem of at present in Chevron osteotomies due to the stability of goose saw and patient's experience, have more concurrent
Disease：1. due to not stopping when osteotomy, osteotomy damages metatarsal heads, iatrogenic fracture occurs, influence osteotomy rear stability or
Metatarsal heads blood is transported；2. due to the swing of goose saw itself, the iatrogenic cripetura of first metatarsal bone distal end is easily caused in osteotomy, to
There is metastatic metatarsalgia.
It is there is no at present about the dedicated osteotomy device patent of Chevron osteotomies or clinical literature report.
Invention content
