OBJECTIVETo study clinical effects of minimally invasive, effective and economic operational method for the treatment of medial malleolus fractures.

METHODSFrom March 2008 to August 2010, 19 patients (12 males and 7 females, ranging in age from 17 to 42 years, averaged 31.7 years) with medial malleolus fractures were reviewed. Closed reduction and percutaneous internal fixation were applied, with a hollow compression screw inserted at the centre and perpendicularly to the fracture surface. A Kirschner wire was inserted through the cortical bone of opposite side and in accordance with the axis of inner malleolus. Postoperative therapeutic effect was evaluated by Kaikkonen sprained ankle scoring system and imageology examination.

RESULTSAll the patients got primary healing of incisions and were followed up, the duration ranged from 6 to 30 months, with an average of 18.7 months. All the patients obtained bone union. Clinical healing time ranged from 2.6 to 3.8 months, averaged 3.2 months. According to Kaikkonen scoring system, the results were rated as excellent in 5 cases, good in 10 cases, moderate in 3 cases, and poor in 1 case.

CONCLUSIONIt is a minimally invasive, effective and economic method to treat medial malleolus fractures by closed reduction and percutaneous internal fixation with hollow compression screw and Kirschner wire.
