[The pararectus approach: surgical procedure for acetabular fractures].

objectiveThe pararectus approach was rediscovered several years ago for pelvic surgery and described as an alternative approach especially for the treatment of acetabular fractures of the anterior column involving the quadrilateral plate. INDICATIONS: For optimal visualization of acetabular fractures involving the quadrilateral plate, fractures of the anterior wall and anterior column, anterior column/posterior hemitransverse fractures, and fractures with central impression of dome fragments, the pararectus approach has proven to be a useful access. CONTRAINDICATIONS: The pararectus approach is not used for posterior column fractures, posterior wall fractures, combined posterior wall and posterior column fractures, transverse fractures with displaced posterior column or in combination with posterior wall fractures, and T‑fractures with displaced posterior column or in combination with posterior wall fractures. SURGICAL TECHNIQUE: The entire pelvic ring, including the quadrilateral plate, can be accessed via the pararectus approach. The choice of the correct surgical window depends on the fracture location and the requirements of fracture reduction. POSTOPERATIVE MANAGEMENT: In general, partial weight-bearing should be maintained for 6 weeks, although earlier weight-bearing release may be possible if necessary, depending on fracture pattern and osteosynthesis. Particularly in geriatric patients, partial weight-bearing is often not possible, so that early and often relatively uncontrolled full weight-bearing has to be accepted.

resultsIn a comparative gait analysis between patients following surgical stabilization of an isolated unilateral acetabular fracture through the pararectus approach and healthy subjects, sufficient stability and motion function of the pelvis and hip during walking was already evident in the early postoperative phase.
