The best method of treating unstable pelvic fractures that involve
the obturator ring is still a matter for debate. This study compared
three methods of treatment: nonoperative, isolated posterior fixation
and combined anteroposterior stabilization. The study used data from the German Pelvic Trauma Registry and
compared patients undergoing conservative management (n = 2394),
surgical treatment (n = 1345) and transpubic surgery, including
posterior stabilization (n = 730) with isolated posterior osteosynthesis
(n = 405) in non-complex Type B and C fractures that only involved the
obturator ring anteriorly. Calculated odds ratios were adjusted
for potential confounders. Outcome criteria were intraoperative
and general short-term complications, the incidence of nerve injuries,
and mortality.Aims
Patients and Methods
The suicidal jumper's fracture of the pelvis is a special form of sacrum fractures associated with high energy trauma. The typical H-type fracture pattern runs transforaminal on both sides with a connecting transverse component between S1 and S3. Due to the high-grade instability operative treatment is imperative. Aim of this study was to compare iliosacral double screwing (2×7,3mm canulated screw with 16mm thread) with spinopelvic internal fixation. Both methods were tested on 6 synthetic and 6 anatomical pelvises. After osteotomy and alternating osteosynthesis stability was tested with a universal testing machine (Zwick) in a simulated two-leg stand. Data were generated by a 3-dimensional computer-assisted ultrasoundsystem (Zebris©) (3 translational datasets x,y,z and 3 ankles). Testing was performed after preload of 50N and two setting cycles of 100N followed by a full load cycle of 150N. ASCII-data were then transferred to SPSS for statistical analysis.Background
