چکیده (انگلیسی):

Introduction: Distal radius fracture (DRF) accompanied by intra-articular volar displaced fragment is
difficult to reduce. This volar fragment remains when treated with a simple buttress effect alone, and Vshaped
deformity may remain on the articular surface. We attempted to improve dorsal rotational deviation
of volar fragment by osteosynthesis applying the condylar stabilizing technique. We report the
surgical procedure and results.
Materials and methods: The subjects were 10 cases of DRF accompanied by intra-articular volar displaced
fragments surgically treated (mean age: 69 years old). The fracture type based on the AO classification
was B3 in 1 case, C1 in 4, C2 in 2, and C3 in 3 cases. All cases were treated with a volar locking plate.
Reduction was applied utilizing the angle stability of the volar locking plate, similarly to the condylar
stabilizing technique. On the final follow-up, we evaluated clinical and radiologic evaluation. To evaluate
V-shaped valley deformity of the articular surface, the depth of the lunate fossa of the radius was
measured using computed tomography (CT).
Results: The duration of postoperative follow-up was 11 (6e24) months. Mayo wrist score was 93
(Excellent in 10 cases). No general complication associated with a volar locking plate was noted in any
case. Volar tilt on radiography were 11 (4e14). The depth of the lunate fossa on CT was 3.9 ± 0.7 mm in
the patients.
Conclusion: This procedure may be useful for osteosynthesis of distal radius fracture accompanied by
intra-articular volar displaced fragments.
