ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical and function efficacy of the treatment of Herbert B2-type scaphoid fracture through volar approach with double screws prograde internal fixation.</p><p><b>METHODS</b>From December 2005 to June 2010,18 patients with Herbert B2-type scaphoid fracture were treated with double screws prograde internal fixation through volar approach, including 14 males and 4 females with an average age of 33.11 years (ranged from 21 to 52 years). The fracture healing situation was evaluated by X-ray examination. Functional outcome was assessed by using Modified Mayo wrist score.</p><p><b>RESULTS</b>All patients were followed up with a mean time of (25.06 +/- 4.00) months. The bone healing time was (3.55 +/- 0.65) months. The pain,passive range of motion, grip of wrist were improved at 4 months after operation (P < 0.05). The Mayo wrist score were improved from preoperative 42.78 +/- 7.32 at 4 months after operation (93.89 +/- 5.83) (P < 0.05), the results were excellent in 9 cases and good in 9 cases.</p><p><b>CONCLUSION</b>Volar approach with double screws prograde internal fixation is an efficacy and safety surgical technique for Herbert B2-type scaphoid fracture.</p>
