title: [Pelvic clamps for controlling shock in posterior pelvic ring injuries. Application, biomechanical aspects and initial clinical results].
abstract: The antishock pelvic clamp provides direct reduction and compression of unstable posterior pelvic ring disruptions. This is effective in preventing excessive blood loss, which is common in these fractures. Comparable to a carpenter's C-clamp, this device is applied in less than 10 min and exerts transverse compression directly over the iliosacral region, reducing the displaced sacral fractures or SI joint diastasis. Early reduction closes the bleeding surfaces and restores the intrapelvic space, providing for earlier tamponade, further decreasing blood loss. The clamp does not interfere with a possible subsequent laparotomy or necessary diagnostic procedures. On 10 cadaveric pelvic specimens the bone yield under compression with the pelvic clamp ranged from 135 N to 685 N relative to the mechanical quality of the bone. This is sufficient to stabilize the posterior ring during further manipulation of the patient in the early phase. Details of the application technique and our clinical experience with the pelvic clamp in the first 17 patients are discussed.
