Surgical procedures: extensile lateral approach (a), dissect and expose the fracture site (b), the fragment is comminuted and dissociative sometimes (c), “on-table” technique was used for this type of fractures (d), temporary fixation with Kirschner wires after the fracture anatomical reduction (e, f), observe the quantity of fracture reduction with intraoperative fluoroscopy (g, h), countersunk screws were used to fixate from the anterior side to the posterior side of articular surface (i, j), mini-plate were adhered beneath the articular surface of the capitellum for the anti-sliding fixation, without the of the obstruction of humeroradial joint (k, l), use two mini-plate for some Dubberley B type fractures, one is placed on anterolateral side and another is placed on posterolateral side (m, n), intraoperative fluoroscopy is used to determine the fracture reduction again and the placement of implants (o, p)
