![]() This technique is simple to learn and minimally invasive, and the results are satisfactory. Our percutaneous leverage technique with DACK wire fixation can be successfully used to treat these fractures. Only one patient suffered from a superficial infection, which was resolved after the removal of the k-wires and the administration of oral antibiotics. There were no refractures and no incidences of nonunion, growth arrest in the proximal epiphysis. Cosmetic results were described as good and satisfactory by all patients. The clinical outcomes were evaluated by the modified Mayo score: 15 patients had an excellent outcome, and one patient had a good outcome. The average angulation (preoperation: 50.5° (range 40.8°–67.0°) vs postoperation: 5.0° (range 0.0°–7.0°)) significantly changed from pre to post-surgery ( P < 0.05). Bone union was achieved in all patients within a mean time of 4.2 weeks (range 4–6 weeks). Percutaneous leverage reduction and DACK wire fixation were successfully performed within an average total surgery time of 20 min (range 12–32 min). The patients included 9 girls (56.2%) and 7 boys (43.8%), with an average age of 10.8 years (range 7.5 to 14.0 years). The level of significance was set to be p < 0.05. The results were assessed using the modified Mayo score. 16 patients were followed up for a mean of 32 months (range 24–41 months). No patients were treated with open reduction. Percutaneous leverage reduction and DACK wire fixation were successfully performed for 17 patients. The injured arm, including the entire first ray, was immobilized with a thumb-spica cast for 4–6 weeks and evaluated radiologically and clinically. Methodsįrom October 2011 to September 2015, A total of 17 patients with severely angulated RW-C thumb metacarpal base fractures were treated at our hospital. We report experiences of percutaneous leverage reduction and dual antegrade crossing Kirschner (DACK) wire fixation in these fractures, aiming to assess the results using our reduction technique. Management of severely angulated Rockwood and Wilkins’ type C (RW-C) thumb metacarpal base fractures in children is challenging. ![]()
