This study investigates the bone and tissue response to degrading magnesium pin implants in the growing rat skeleton by continuous in vivo microfocus computed tomography (μCT) monitoring over the entire pin degradation period, with special focus on bone remodeling after implant dissolution. The influence of gas release on tissue performance upon degradation(More)
Although equinus gait is the most common abnormality in children with spastic cerebral palsy (CP) there is no consistency in recommendations for treatment, and evidence for best practice is lacking. The Baumann procedure allows selective fractional lengthening of the gastrocnemii and soleus muscles but the long-term outcome is not known. We followed a group(More)
Avulsion fractures of the ischial tuberosity are rare sports injuries typically occurring in young athletes. Their misdiagnosis may lead to chronic pain or disability. The aim of this study is to report a retrospective series of patients sustaining a fracture of the ischial tuberosity and to propose decision guidelines. The mechanism of accident, the(More)
BACKGROUND Dislocations of the sternoclavicular joint are rare injuries caused by massive forces applied to the joint. A high rate of complications has been reported following this injury emphasizing the importance of an accurate diagnosis and therapy. METHODS We report a series of patients with chronic anterior or posterior sternoclavicular instability(More)
Injuries in childhood and adolescence are frequent and the knee is one of the most common sites of injuries. This study aimed to analyze the epidemiology, gender distribution, age, and circumstances of knee injuries in childhood at a Level I Trauma Center in Austria. All pediatric and adolescent trauma patients who presented in a 2-year period were(More)
Type A fractures of the spine requiring operative stabilization are rare injuries in the pediatric population. Current reports have demonstrated the safety of the combination of balloon kyphoplasty and minimal invasive management of thoraco-lumbar fractures in adults. There is no information about the efficacy of this approach in managing pediatric(More)
AIM Information on the timing and long-term outcome of single-event multilevel surgery in children with bilateral spastic cerebral palsy (CP) walking with flexed knee gait is limited. Based on our clinical experience, we hypothesized that older children with bilateral spastic CP would benefit more from single-event multilevel surgery than younger children.(More)
OBJECTIVES To detect outcome measures that could help differentiate between dynamic and fixed equinus (FEQ) deformities in children with cerebral palsy, and secondary, to describe the function of the gastrocnemius and soleus (SOL) muscles when either dynamic triceps surae tightness or FEQ contracture is present. DESIGN A group-comparison study. SETTING(More)
In this study various biodegradable materials were tested for their suitability for use in osteosynthesis implants, in particular as elastically stable intramedullary nails for fracture treatment in paediatric orthopaedics. The materials investigated comprise polyhydroxybutyrate (PHB), which belongs to the polyester family and is produced by microorganisms,(More)
Injections into the subtalar joint may be performed for diagnostic or therapeutic reasons. The anterolateral approach is most commonly utilised for this purpose. We evaluated the success of an intra-articular puncture by using the anterolateral in comparison to the posterolateral approach. Sixty-eight cadaver adult feet were used for performing injections(More)
