| Abstract |
|
Radioulnar synostosis is a rare but well-recognized and functionally disabling complication of forearm fracture. There is a paucity of data about post-traumatic radioulnar synostosis, an unusual but serious complication of forearm fractures. Particularly if the dominant arm is affected, the functional disability that result is considerable. The factors associated with the synostosis are the fractures at the same level, the application of onlay grafts, one incision approach, severe comminution of the fractures with interosseous membrane tear, biceps tendon injury at the insertion portion and children with displaced radial neck fracture. Treatment methods have included excision of the synostosis with interposition of fat, muscle, silicone rubber sheets or absorbable gelatine sponge, excision of the proximal radius, insertion of a transosseous screw to separate the bones after excision and derotational osteotomy have been described as other treatment method. In our cases, we present seven cases of successful radioulnar synostosis excision with interposition of soft tissue. The result of the average active range of motion was 80¡Ædegree pronation and 60¡Ædegree supination. |
