Abstract
Standard external fixators have always caused difficulties in visualising fracture fragments radiologically in both planes; for this reason multiple shots are often required, exposing patients and surgeons to high X-ray levels. Radiolucent external fixator X-calibre is composed of a new thermoplastic material reinforced by carbon fibres (PEEK-CA 30). The aim of this study is to evaluate the first 30 tibial fractures treated with this device.
Thirty external fixators X-calibre were used to treat 30 patients with tibial fractures with an average age of 40.4 years (range 21–60). According to the AO classification we have treated nine type A, 13 type B, and eight C fractures. Five were open fractures. The average follow-up was of 18 months. The time of healing was the same as seen using the standard fixator and the average time was 115 days (range 85 to 190). One tibial plafond fracture healed with 8° valgus deformity and persistence of pain during walking. There was loss of reduction on the third day after surgery due to erroneous evaluation of the fracture, which presented a butterfly fragment.
This new radiolucent fixator showed the following advantages: single use, sterile package, radiolucency, less X-ray exposure for patients and surgeons, deal mechanical performance for each use, reduced storage and sterilisation costs, less instrumentation, less weight and increased comfort for the patient, average healing time and results comparable to the existing radio-opaque system.
