- Discussion:
- frx of body of navicular may be associated w/
mid-tarsal joint injuries;
-
classification: 3 types:
-
coronal plane fracture w/ no angulation of the forefoot;
- displaced frx require ORIF w/ lag screw fixation;
- thru dorsomedial longitudinal incision, frx can be visualized;
-
frx line is dorsolateral to plantar medial
- forefoot is displaced medially;
- reduction is difficult to maintain, because there is frequent comminution of the plantar lateral fragment;
-
fracture is comminuted & forefoot is displaced laterally;
- results are usually poor;
- Radiographs:
- frequently navicular body frxs are only seen on lateral projection;
- Non Operative Treatment:
- if these fractures are truly non displaced, they are treated w/ a below knee walking cast for 6 weeks;
- Operative Treatment:
- if frx is even minimally displaced, closed treatment is of little value because even if reduction can be achieved,
recurrent displacement of fragments usually occurs;
- late arthritis is common;
