title: Minimally invasive plate osteosynthesis in type B fibular fractures versus open surgery.
abstract: BACKGROUND
  In traumatology, the search for better surgical access points has led to the increased use of the minimally invasive plate osteosynthesis (MIPO) technique. There are few studies on the treatment of distal fibular fractures with MIPO. Locking compression plates (LCP) for distal fibular fractures is generally applied after open reduction, but may involve complications to the surgical wound. In this study, we compared two groups of patients receiving either ORIF or MIPO, in order to analyse the advantages and disadvantages of the two techniques.
  
  
  METHODS
  Two homogeneous groups of patients (18 + 18) received LCP for distal fractures of the fibula, type B, according to AO. Group A patients underwent open surgery, whereas Group B patients received plates applied with the MIPO technique. Both groups were examined physically and radiographically 1 and 3 months after the two types of procedure and then 1 year later, with functional assessment according to Olerud and Molander.
  
  
  RESULTS
  ROM Group A: 5° reduction in tibiotarsal extension in 8 patients and 5° in supination in 1 patient; Group B: 5° reduction in extension in 7 cases. Mean healing time: 3 months (range 2-4) in Group A and 2.9 (range 2-4) in Group B. Dehiscence of the surgical wound was observed in five Group A patients, but none in Group B. Functional assessment according to Olerud and Molander was 87.4 points in Group A (range 80-100) and 95.6 in Group B (range 82-100).
  
  
  CONCLUSIONS
  We believe that the MIPO technique for distal fractures of the fibula should be used more often, especially if soft tissue is in a critical condition. Healing times should be reduced in the more complex cases. It is important that the learning curve should be improved, to minimize exposure to radioscopy and possible damage to the superficial fibular nerve.
