  abstract  = {Operative treatment of ruptured pubic symphysis by plating is often accompanied by complications. Trans-obturator cable fixation might be a more reliable technique; however, have not yet been tested for stabilization of ruptured pubic symphysis. This study compares symphyseal trans-obturator cable fixation versus plating through biomechanical testing and evaluates safety in a cadaver experiment. APC type II injuries were generated in synthetic pelvic models and subsequently separated into three different groups. The anterior pelvic ring was fixed using a four-hole steel plate in Group A, a stainless steel cable in Group B, and a titan band in Group C. Biomechanical testing was conducted by a single-leg-stance model using a material testing machine under physiological load levels. A cadaver study was carried out to analyze the trans-obturator surgical approach. Peak-to-peak displacement, total displacement, plastic deformation and stiffness revealed a tendency for higher stability for trans-obturator cable/band fixation but no statistical difference to plating was detected. The cadaver study revealed a safe zone for cable passage with sufficient distance to the obturator canal. Trans-obturator cable fixation has the potential to become an alternative for symphyseal fixation with less complications.},

  abstract  = {The aim of this study was to compare two different techniques of performing one-level spondylodesis for thoracolumbar burst fractures using either an autologous iliac crest bone graft (ICBG) or a porous tantalum fusion implant (PTFI). In a prospective nonrandomized study, 44 patients (20 women, 24 men; average age 43.1 +/- 13.2 years) suffering from severe thoracolumbar burst fractures were treated with combined anterior-posterior stabilization. An ICBG was used in 21 cases, and a PTFI was used in the other 23 cases. A two-year clinical and radiographic follow-up was carried out. There were no statistically significant differences in age, sex, localization/classification of the fracture, or visual analog scale (VAS) before injury between the two groups. All 44 patients were followed up for an average period of 533 days (range 173-1567). The sagittal spinal profile was restored by an average of 11.1 degrees (ICBG) vs. 14.3 degrees (PTFI) (monosegmental Cobb angle). Loss of correction until the last follow-up tended to be higher in the patients treated with ICBG than in those treated with PTFI (mean: 2.8 degrees vs. 1.6 degrees). Furthermore, significantly better restoration of the sagittal profile was obtained with the PTFI than with the iliac bone graft at the long-term follow-up (mean: ICBG 7.8 degrees, PTFI 12.3 degrees; p < 0.005). Short-segment posterior instrumentation combined with anterior one-level spondylodesis using either an ICBG or a PTFI resulted in sufficient correction of posttraumatic segmental kyphosis. PTFI might be a good alternative for autologous bone grafting and prevent donor site morbidities.},

  abstract  = {We report on a 14 months old toddler who sustained a traumatic hemipelvectomy by being crushed between a car and a stone wall. After stabilization in the resuscitation room he was treated operatively by laparotomy, osteosynthesis of the pelvic ring, reconstruction of the both external iliac vessels and the urethra and reposition of the testicles. After 66 days he was discharged into rehabilitation. Implants were removed after eight months. 20 months after the injury, the leg was plegic, initial radiological signs of femoral head necrosis showed up but the infant was able to walk with an orthesis and a walker. Up to our knowledge, this is the youngest patient described in the literature with a survived traumatic hemipelvectomy and salvaged limb.},

  abstract  = {Hintergrund Die Symphysensprengung mit entsprechender Diastase kann durch eine Symphysenplatte stabilisiert werden. Fragestellung Welche Beckenverletzungen werden mit einer Symphysenplatte stabilisiert und wie ist das Outcome? Material und Methoden Retrospektive Auswertung von 64 Patienten {\"u}ber einen Untersuchungszeitraum von 24 Monaten. Ergebnisse Es waren 56 Patienten m{\"a}nnlich, 8 weiblich und das mittlere Alter betrug 44 Jahre (SD ± 17). Unf{\"a}lle im Straßenverkehr waren der f{\"u}hrende Grund f{\"u}r die Beckenverletzung. Die Verteilung nach AO-Klassifikation zeigte sich wie folgt: 14-mal B1-, 10-mal B2-, 5‑mal B3-, 23-mal C1-, 9‑mal C2- und 3‑mal C3-Verletzungen. Die Verteilung nach Young und Burgess ergab: 9‑mal APC-I-, 18-mal APC-II-, 13-mal APC-III-, 9‑mal LC-I-, 3‑mal LC-II-, 2‑mal LC-III- und 10-mal VS-Verletzungen. Der mittlere Injury Severity Score (ISS) betrug 32 und die mittlere station{\"a}re Verweildauer 29 Tage (pos. Korrelation p ≤ 0,001). Im Verlauf war eine radiologische Implantatlockerung bei 52 Patienten nachweisbar. Therapierelevante Komplikationen gab es in 14 F{\"a}llen. Hierbei war das Implantatversagen (n = 8) der Hauptgrund f{\"u}r eine operative Revision. Diskussion Obwohl die radiologische Implantatlockerung h{\"a}ufig beobachtet wird, ist sie nur selten Grund f{\"u}r einen Revisionseingriff. Kommt es hingegen zum vollst{\"a}ndigen Implantatversagen, tritt dies meist innerhalb der ersten postoperativen Wochen auf und ist revisionsbed{\"u}rftig. Eine fr{\"u}hzeitige Abkl{\"a}rung durch R{\"o}ntgenbildgebung sollte bei Verdacht erfolgen.},
