DECISION MAKING INITIAL STABILIZATION WITH EXTERNAL TEMPORARY FIXATION IN EMERGENCY AND CONVERSION TO CIRCULAR EXTERNAL FIXATION AS DEFINITIVE TREATMENT

Abstract

What was the question? The treatment of multi-injured patients requires initial stabilization of general conditions and vital parameters. The first stage in orthopedic management of the fractures in trauma involves stabilization of the bone segments to reduce blood loss and allow nursing. External fixators are fast, versatile and essential in the emergency situation in cases of multiple fractures, especially with soft tissue loss. According to damage control orthopedics (DCO) concepts, it is possible to replace an external fixator (EF) with internal synthesis (ORIF) after a period of time to reduce the risks of ORIF. However, surgery can be difficult to perform and pin sites can be the source of bone infection, in which the EF as a definitive treatment option may be considered. How did you answer the question? In trauma surgery, instability of the hardware, fractures near the joint, frame extending across the knee and the ankle, initial fixation was converted to definitive treatment with circular frames according to the Ilizarov method. Fourteen patients (2 female and 12 males; age 24 to 80 yrs, average age 43,4 y/o) were treated with various circular framses as definitive treatment: Ilizarov (2), Sheffield (7), Taylor Spatial Frame (TSF) (4) and TrueLok (1) between November 2002 and December 2007 in multiply injured patients with ISS > 20. Seven cases were femoral and seven tibial. The femoral group had four knee spanning fixator configurations and three unilateral external fixators. The tibial group had 4 unilateral frames, 1 hybrid EF, 1 across the knee EF and 1 across the ankle EF. Five patients had temporary femoral and tibial hardwares in the same side. Three patients had unilateral tibial and femoral fractures. What are the results? All patients achieved consolidation. The mean duration of femoral EF was 7.6 months (5–9 months). One bone loss in a distal femoral shaft treated with Sheffield EF had lengthening (5 cm) after acute short-hening. Two patients had a gradual distal femoral fracture reduction and a mechanical axis correction by TSF. Three patients with tibial bone loss had 2 trifocal bone transport (17,5 and 9 cm) and 1 bifocal bone transport 5 cm. The TSF had no additional pre-operative planning and major post-operative frame adjustments. The intra-operative devices was easier for the TSF. What are your conclusions? Circular frame osteosynthesis following initial EF, is a reliable and effective strategy for treatment in severe open femur and tibia fractures and post traumatic reconstruction.
