Brief summary

Multicentre Prospective Randomized Clinical Trial, to evaluate patients after surgery for extra-articular tibial fractures treated with Smith& Nephew's Trigen META intramedullary nailing system; comparing two surgical techniques: Group A=standard technique(90º of knee flexion) and Group B=with the semi-extended surgical technique. (2\*100 patients) Research Objectives: The primary research objectives are to evaluate: i) anterior knee pain and ii) the nail position and overall fracture alignment Outcome Measures: 1. Nail positioning by means of intra-operative fluoroscopy and post operative x-rays. 2. Anterior Knee pain by means of VAS-scores, a Kneeling test and Subjective outcomes by means of Patient questionnaires 3. Knee-related adverse events 4. Overall fracture alignment

Detailed description

After surgery with standard intramedullary nailing technique in tibia fractures, 40-80% of the patients still complain of anterior knee pain postoperative. The expected advantages of the semi-extended nailing technique is less anterior knee pain and less malunion of the fracture. Using the semi-extended nailing technique also might give the advantage of better position of the nail by a more concentric reaming of the tibia, due to less tension on the patella tendon during reaming process.

Interventions

PROCEDURESemi-extended Surgical Technique

Surgical technique with the knee in 10-20 degrees of flexion, to implant the intramedullary tibia nail.

Th e Standard surgical techique is implanting the tibia nail with the knee in 90 degrees of flexion.

Inclusion criteria

* Patient has sustained a closed (Tscherne Classification) or open tibial fracture (Gustillo-Anderson Classification) that is amendable for operative fixation with an intramedullary nail. * Patient has an isolated tibia and fibula fracture * Skeletally mature * Patients aged between/including 18 to 70 years * Patient has given formal consent to be involved in the trial and has completed the study consent form * Patient is likely to comply with study follow-up requirements

Exclusion criteria

* Pathologic fractures * Other fractures involving the same lower extremity * Soft tissue injuries/problems that would prevent the surgeon from using both of the surgical techniques to insert an intramedullary nail * Patient having pre-existing knee joint disease causing anterior knee pain * Patient likely to have problems with follow-up * Patient unwilling to give informed consent to be included in the trial

Design outcomes

Primary

MeasureTime frameDescription
Anterior Knee Pain4, 6 and 12 months post-operativeAnterior Knee pain will be measured through a Kneeling test (time a patient is able to rest on his operated knee)

Secondary

MeasureTime frameDescription
Nail positioningOperation (day 1)Measure by means of fluoroscopy and standard x-rays during the surgery, the position of both the guide wire and the intramedullary nail.
