Homeless individuals suffer a greater burden of health problems than the general population. This study aimed to describe the epidemiology of physical trauma among homeless patients presenting to an urban major trauma center and to ascertain any differences in the nature, injury severity and outcomes among homeless compared to domiciled patients. ⋯ Among injured patients who presented at an urban trauma center, homelessness was associated with higher odds of assault, intentional self-harm, penetrating injury, psychiatry admissions, DAMA but lower ISS than domiciled patients. Variable definitions of homelessness and lack of standardized documentation in the medical record should be addressed to ensure these vulnerable patients are identified and linked with peripheral services.

Supracondylar femoral fractures account for a noticeable percentage of the femoral shaft fractures, affecting two etiological groups: high energy trauma in young men, with good bone quality, and older women with osteoporotic femur. Surgical treatment of those kind of fractures remains controversial, with different surgical options such as plate and sliding barrel locking condylar plate, less invasive stabilization system (LISS) or intramedullary nailing, which has emerged as a new fixation choice in the treatment of that type of fractures. The present work performs a comparative study about the biomechanical behavior of anterograde and retrograde nailing in supracondylar femoral fractures type A, in order to determine the best choice of nailing and locking configuration. ⋯ The study was focused on the immediately post-operative stage, verifying the appropriate stability of the osteosynthesis. The obtained results show a better biomechanical behavior for anterograde nails, providing a better stability from the point of view of global movements, lower stresses in screws, and less stress concentration in cortical bone. So, for the analyzed fractures and osteosyntheses types, anterograde nailing has demonstrated to be a better surgical option, being an excellent indication in supracondylar fractures of femur, with clear benefits compared to retrograde nailing, providing a better stabilization which enables for a more satisfactory fracture healing.

The medial sural artery perforator (MSAP) flap: A versatile flap for lower extremity reconstruction.
The medial sural artery perforator (MSAP) flap provides a thin, pliable and durable soft tissue reconstruction with adequate pedicle length and low donor morbidity. It is an ideal choice for small-to-moderate defects of the lower extremity, although it does have limitations. We report our experience of the flap in a three-pronged anatomical, clinical and patient reported outcome-based study. ⋯ The MSAP provides robust foot-and-ankle reconstruction, whilst permitting glide when over the knee. Patient satisfaction and functional outcomes are excellent with careful patient selection. Care should be taken to avoid compression or kinking of the large, thin walled veins as the most commonly observed complication was venous congestion. We advocate MSAP as a first choice flap for small-to-moderate foot, ankle or knee defects.

Contemporary uncemented hemiarthroplasties are being used after displaced femoral neck fractures, however, their functional and radiological results remain controversial. The aim of this study was to evaluate the clinical and radiological results of a tapered uncemented stem combined with a uni- or bipolar hemiarthroplasty after a minimum follow-up of ten years. ⋯ Bone fixation can be obtained with a contemporary uncemented stem in hemiarthroplasty for patients over 70 years old with a femoral neck fracture. Acetabular erosion was frequent after ten years, however, the rate of revision surgery was low.

Comparative Study
Comparison of the Charlson Comorbidity Index with the ASA score for predicting 12-month mortality in acute hip fracture.
The ASA (American Society of Anaesthesiologists) Score is the current standard for measuring comorbidity in the Australian Hip Fracture registry, however it has never been validated for this purpose. Subsequently, a more appropriate and useful measure should be investigated. This study aimed to compare the ASA and Charlson Comorbidity Index (CCI) scores in predicting 12-month mortality following acute hip fracture. ⋯ The ASA score is independently associated with 12-month mortality; this was not replicated using either version of the CCI. The data does not suggest using the CCI in registry level datasets for the purposes of predicting 12-month mortality.
