Minimally invasive fixation of pelvic fragility fractures is recommended to reduce pain and allow early mobilization. The purpose of this study was to evaluate the outcome of two different stabilization techniques in bilateral fragility fractures of the sacrum (BFFS).

The reported results of compression fractures are poor. These results are not influenced by the severity of compression, the fracture site or the residual deformity. Otherwise, the factors that determine a patient's recovery are unknown. This study wants to identify the factors determining a patient's recovery after surgical treatment of compression fractures of the thoracolumbar spine. Therefore, in 31 surgically treated patients the pre-injury versus the 12-month follow-up differences in back pain, in global outcome and in participation were prospectively recorded. For this, the visual analogue scale for pain (VAS scale) and the Greenough and Fraser low back outcome scale were used. Of the latter scale, the 3 questions pertaining to participation were combined to create a participation subscale. For these differences and for time lost from work multiple linear regressions with combinations of 16 possible predictors were performed. At one year patients who smoke report a 25% less favorable global outcome and return 2.8 points (out of 10) less closely to their pre-injury pain level than patients who do not smoke. Patients with a fracture at the thoraco-lumbar junction return 3.3 points less closely to their pre-injury level on the VAS scale than those with a lumbar fracture. For each decrease in 1 of the 3 education levels, the patients stay away from work 15 weeks longer. Per degree of sagittal index at follow-up, patients stay 9 days longer at home. For each increase in level of occupation the return to the pre-injury participation level is 10% less favorable. The variability of time lost from work and of recovery of global outcome, pain and participation level explained by our models is 73%, 37%, 25% and 13% respectively. Smoking, localization of the fracture at the thoraco-lumbar junction and a high pre-existent level of occupation are strong negative predictors for recovery. A lower education level and sagittal fracture deformity at follow-up are negative predictors for sick leave but might also reflect the concerns of the physician when deciding about return to work

AIMS. Pure tibial plafond traumatic pathology (excluding trimalleolar fractures) is rare but troublesome, considering the surgical challenges and the long term disability perspective. Treatment involves a wide variety of implants and techniques, and the procedures choice and timing is highly dictated by the soft tissue damage. We designed this study to assess the status of our patients operated with internal, external or combined procedures. METHODS. In a retrospective study, between July 2008 and July 2010 we reviewed 24 patients with available follow-up data. We reviewed the pre- and post-operative imaging available and the immediate follow-up data. A form is currently mailed to the patients to self-evaluate the general physical, mental and employment status, and also the affected limb, using general approved questionnaires. Data from this form is still in process. RESULTS. In this clinic we recorded 24 patients with tibial plafond fractures (17 male, 7 female, 2.43 sex ratio), with ages between 18 and 82 years (average 46.5, median 39 years). According to AO/OTA classification, we noted 8 type A (2 A1, 3 A2, 3 A3) extra-articular tibial fractures, 9 type B (4 B1, 4 B2, 1 B3) intra-articular pilon fractures and 7 type C (3 C1, 1 C2, 3 C3) both epi- and metaphyseal tibial fractures, usually with peroneus fractures at various levels. 10 of these fractures were open, from them 3 type IIIA and 2 IIIB Gustilo-Anderson, and 3 of the patients were politrauma (1 L1 lumbar fracture and distal radius fracture, 1 cranio-cerebral trauma and type I open distal radius fracture and 1 cranio-cerebral trauma). We performed a large array of surgical procedures, usually in emergency, based mainly on the local soft tissue status and both the age and recovery needs of the patient. In old debilitated patients we preferred to use minimal internal osteosynthesis, usually applying a supplementary external fixator or cast. In young active patients we used MIPO techniques in tibial fractures, both with regular or locking-screw plates, repairing also the peroneus in order to preserve the limb length in diaphyseal fractures, and to reconstruct the ankle in lateral malleolus fractures. In cases with severe soft tissue impairment we delayed the definitive osteosynthesis using an external fixator. The short term outcome was good, noting only one septic nonunion, which healed with the appropriate treatment, one calcaneus pin track infection and one deterioration of the external fixator in an alcoholic patient. Data for the mid-term outcome is still under evaluation. CONCLUSIONS. Choosing the appropriate procedure is vital for the outcome. Timing is important, especially in high energy trauma, when the proper surgery performed in emergency allowed us to overcome most of the possible complications. Short term results are encouraging, and the mid-term results will let us know if our attitude was correct

Improvised Explosive Device (IED) attacks on vehicles have been a significant feature of recent conflicts. The Dynamic Response Index (DRI), developed for predicting spinal injury in aircraft ejection, has been adopted for testing vehicles in underbelly blast. Recent papers suggest that DRI is not accurate in blast conditions. We suggest that the distribution of blast and ejection injuries is different. A literature review identified the distribution of spinal fractures in aircraft ejection incidents. A Joint Theatre Trauma Registry search identified victims of mounted IED blast with spinal fractures. The distribution of injuries in the two groups was compared using the Kruskall Wallis test. 329 fractures were identified in ejector seat incidents; 1% cervical, 84% thoracic and 16% lumbar. 245 fractures were identified in victims of mounted blast; 16% cervical, 34% thoracic and 50% lumbar. There was no significant similarity between the two (p=1). There was no statistically significant difference between the distribution of fractures in blast survivors versus fatalities. The difference between blast and ejection injury patterns suggests that injury prediction models for ejection should not be extrapolated to blast mechanisms and that new models need to be developed

Aims

This study aimed to analyze the correlation between transverse process (TP) fractures of the fourth (L4) and fifth (L5) lumbar vertebrae and biomechanical and haemodynamic stability in patients with a pelvic ring injury, since previous data are inconsistent.
