6. A radio-ulnar synostosis is a rare condition which is upper limb
skeletal malformation characterized by bony fusion of the radius
and ulna.
In 1793, Sandifort provided the initial description of congenital type.
Gros described posttraumatic radioulnar synostosis in 1864.
8. For a short time, the radius and ulna share a common
perichondrium.
Abnormal events at this time can lead to a failure of segmentation.
Usually, it’s not discover until early adolescence,
About one third of cases are associated with general skeletal
abnormalities.
9. The most common cause: operatively treated forearm fracture.
Patients with high-energy, comminuted, open fractures.
Monteggia and proximal forearm fractures.
The use of bone graft and screws protruding through the opposite
cortex.
Any trauma causing hematoma formation.
12. Physical examinations:
pronation and supination blocked
both actively and passively.
Investigations:
Radiographs:
AP and lateral of forearm, elbow, and wrist.
13. non operative:
Observation.
Operative:
osteotomy with fusion.
surgical resection of synostosis, irradiation, and indomethacin.
proximal radial excision.
Postoperative rehabilitation:
Splinting in maximum pronation and supination between passive
and active physiotherapy.
