Paralytic ileus is a temporary inhibition of gastrointestinal mobility in the absence of mechanical obstruction. Ileus has previously been observed in up to 40% of patients undergoing bowel surgery, leading to increased morbidity and length of stay. Pelvic and acetabular fractures are often caused by high energy trauma and are associated with a risk of visceral injury. Prior to this study, there were no reported figures for the incidence of ileus in patients presenting with pelvic and/or acetabular fractures. ⋯ This is the first study to report the incidence of and risk factors for ileus following admission with pelvic and/or acetabular fractures. Due to the morbidity and cost associated with this condition, further research is required to assess the effect of interventions to reduce its incidence in this patient subgroup.

The primary aim was to determine independent patient, injury and management-related factors associated with symptomatic venous thromboembolism (VTE) following acute Achilles tendon rupture (ATR). The secondary aim was to suggest a clinical VTE risk assessment tool for patients with acute ATR. ⋯ Age ≥50 years, personal history of VTE/thrombophilia and a positive family history were independently associated with VTE following ATR. Incorporating age into our suggested VTE risk assessment tool enhanced its sensitivity in identifying at-risk patients. Early weight-bearing in an appropriate orthosis may be beneficial to all patients in VTE risk reduction.

Compression sonography has been introduced for non-invasive measurement of compartment compressibility and possible diagnostic tool for acute or chronic compartment syndrome in studies using human cadavers and animal models. To date, standard values in healthy subjects are not yet defined. The aim was to define standard compartment compressibility values in healthy human subjects and to assess the reliability of this measurement method. ⋯ In healthy volunteers between 18 and 50 years of age, mean compartment compressibility ratio R10-80 was 15.9% ±3.6, independent of demographic factors and sport activity. Application of 10mbar instead of 0mbar increased image quality. Subsequently, R10-80 showed lower standard deviation and both higher intraobserver and interobserver reliability than R0-80. Using R10-80, this measurement method is reliable with very high intra- and interobserver correlation.

Intra-articular impacted fragment (IAIF) was considered as the articular surface fragment resulting from impact and compressive forces. Malreduction of IAIF in posterior malleolar fractures was associated with the cause of talus subluxation and long-term arthritis. ⋯ So we established IAIF defect finite element model in posterior malleolar fractures and explored the effect of IAIF defect in ankle joint. We also discussed the relation between IAIF defect and post-traumatic arthritis.

Timing of hip fracture surgery for the internal fixation of an intracapsular fracture remains controversial and few studies to date have been able to determine the optimum time to surgery in minimizing osteonecrosis and non-union with intracapsular fractures after fixation. ⋯ Our study demonstrates no relationship between timing of surgery for fixation of intracapsular fracture and complication rates. Female sex and fracture displacement increased risk of complications whereas independent mobility and use of Targon® screw device in comparison to parallel screws were protective against non-union but not avascular necrosis.
