OBJECTIVE: Vehicle safety is improving, thus decreasing the number of life-threatening injuries and increasing the need for research in other areas of the body. The current child anthropomorphic test device (ATD) does not have the capabilities or instrumentation to measure many of the potential interactions between the lower extremity and the vehicle interior. A prototype Hybrid III 6-year-old ATD lower extremity (ATD-LE) was developed and contains a tibia load cell and a more biofidelic ankle...

Athletic children are prone to overuse injuries, especially at the heel and knee. Since footwear is an extrinsic factor of lower limb injury risk, the aim of this study was to assess the influence of shoe aging on children running biomechanics. Fourteen children active in sports participated in a laboratory biomechanical evaluation. A new pair of shoes was provided to each participant at an inclusion visit. Four months later, the participants performed a running task and their kinematics and kinetics were assessed both with their used shoes and with a new pair of shoes identical to the first...

BACKGROUND: Falls are the leading cause of injury in stroke patients. However, the cause of a fall is complicated, and several types of risk factors are involved. Therefore, a comprehensive model to predict falls with high sensitivity and specificity is needed. METHODS: This study was a prospective study of 112 inpatients in a rehabilitation ward with follow-up interviews in patients' homes. Evaluations were performed 1 month after stroke and included the following factors: (1) status of cognition, depression, fear of fall and limb spasticity; (2) functional assessments [walking velocity and the Functional Independence Measure (FIM)]; and (3) objective, computerized gait and balance analyses...

REVIEW
Ralph Gaulke, Christian Krettek
Because of the complex fracture morphology and vulnerable soft tissue coverage, fractures of the tibial pilon are difficult to treat. Complications are more common than in bi- or trimalleolar fractures. The surgeon has to know about the special risks of these injuries to avoid complications. Early complications are soft tissue necrosis, persisting fragment dislocations after surgery, loss of reposition and deep wound infection. The surgeon has to be aware of early signs of compartment-syndrome and chronic regional pain syndrome (CRPS)...

BACKGROUND: Despite the presence of a tiered in-hospital trauma triage system for the past decade, trauma centers still struggle with a definitive list of highest level activation criteria. In 2002, the American College of Surgeons (ACS) mandated 6 criteria for highest level activation. However, it is unknown if pediatric trauma centers follow these criteria. The purpose of this study is to identify and categorize the highest level pediatric trauma criteria used by pediatric trauma centers in the United States...

LLow ankle sprains are common injuries in young athletes. Hence, it is imperative that low ankle sprains are diagnosed and treated quickly and effectively. We reviewed the: (1) anatomy; (2) imaging; (3) physical exam findings; and (4) treatment modalities regarding these injuries. Plain radiographs are standard of care and routine MRI is not recommended for suspected sprains. However, physical exam findings often may guide management decisions. The majority of patients diagnosed with low ankle sprains are treated with a one- to two-week immobilization period with physical therapy focused on peroneal proprioception and strength...

The ankle and foot are commonly injured during sporting activities. Clinical diagnosis can at times be challenging, due to the complex anatomy and multiple sites of potential injury. In the athlete, there is a reduced threshold for imaging to clarify diagnosis, guide prognosis, and treatment. Diagnostic imaging is also helpful in evaluating ongoing symptoms in the subacute or chronic setting. (©) RSNA, 2017.

Angela Seidel, Fabian Krause, Martin Weber
BACKGROUND: Isolated lateral malleolar fractures may result from a supination-external rotation (SER) injury of the ankle. Stable fractures maintain tibiotalar congruence due to competent medial restraints and can be treated nonoperatively with excellent functional results and long-term prognosis. Stability might be assessed with either stress radiographs or weightbearing radiographs. METHODS: A consecutive series of patients with closed SER fractures (presumed AO 44-B1) were prospectively enrolled from 2008 to 2015...

OBJECTIVE: Biomechanical data from post mortem human subject (PMHS) experiments are used to derive human injury probability curves and develop injury criteria. This process has been used in previous and current automotive crashworthiness studies, Federal safety standards, and dummy design and development. Human bone strength decreases as the individuals reach their elderly age. Injury risk curves using the primary predictor variable (e.g., force) should therefore account for such strength reduction when the test data are collected from PMHS specimens of different ages (age at the time of death)...

Pilon fractures are high-energy injuries that often result in considerable edema and compromise of the soft tissue envelope of the ankle. These injuries are typically staged with an external fixator until the soft tissue is amenable for definitive fixation. This study was conducted to determine the effects of lymphedema treatment for the management of pilon fractures. Patients who underwent open reduction and internal fixation of pilon fractures between 2007 and 2014 at the authors' level II trauma center were identified by Current Procedural Terminology codes indicative of placement of an external fixator (20690) and open reduction and internal fixation of a pilon fracture (27826, 27827, or 27828)...
