Research paper thumbnail of The Relationship between the School Function Assessment (SFA) and the Gross Motor Function Classification System (GMFCS) in Ambulatory Patients with Cerebral Palsy

Through correlation, regression, and ANOVA analysis, data from 103 children were examined. A regression model was used to compare SFA-predicted versus actual GMFCS levels. One-way ANOVA was utilized to determine differences between SFA subscale scores in the context of GMFCS. A significant correlation between composite SFA scores and GMFCS levels (r = -0.847, p < 0.020) was observed. Subscale-SFA and GMFCS correlations included Regular Class (r = -0.338, p < 0.001), Physical Tasks Adaptation (Phys1; r = -0.340, p < 0.001) and Assistance (Phys2; r = -0.340, p < 0.001), Position (r = -0.338, p<0.001), Recreational Movement (RecMvmt; r = -0.387, p <0.0001), Manipulation Movement (ManMvmt; r = -0.494, p < 0.0001), and Up/Down Stairs (UDStairs; r = -0.453, p< 0.0001). Between predicated and actual GMFCS levels, no statistical difference was observed. One-way ANOVA demonstrat...

Research paper thumbnail of Complex ankle arthrodesis: Review of the literature

Risk factors that contribute to defining this group of patients can be divided into systemic factors and local factors pertaining to co-existing ankle or hindfoot pathology. Orthopaedic surgeons should be aware of these risk factors and their association with patients&#39; outcomes after complex ankle fusions. Both external and internal fixations have demonstrated positive outcomes with regards to achieving stable fixation and minimizing infection. Recent innovations in the application of biophysical agents and devices have shown promising results as adjuncts for healing. Both osteoconductive and osteoinductive agents have been effectively utilized as biological adjuncts for bone healing with low complication rates. Devices such as pulsed electromagnetic field bone stimulators, internal direct current stimulators and low-intensity pulsed ultrasound bone stimulators have been associated with faster bone healing and improved outcomes scores when compared with controls. The aim of this review article is to present a comprehensive approach to the management of complex ankle fusions, including the use of biophysical adjuncts for healing and a proposed algorithm for their treatment.

Research paper thumbnail of Absorbable and non-absorbable cement augmentation in fixation of intertrochanteric femur fractures: systematic review of the literature

Two reviewers independently assessed the methodological quality and extracted relevant data from each included study. In cases in which the outcomes data were similar between studies, data were pooled and analyzed. Seven studies were included after fulfilling all inclusion and exclusion criteria. Two hunderd and eighty patients were treated with augmentation and 175 were treated without augmentation. Studies were variable in their ability to demonstrate better functional outcomes in patients who underwent augmentation. However, radiographic parameters (mean lag screw sliding distance and varus deformity) were better in the augmentation group. In terms of complications, failure to use augmentation with a sliding hip screw device in five studies led to 10.8-fold higher likelihood of construct failure (p \ 0.01). Augmentation of intertrochanteric femur fractures with polymethyl methacrylate or calcium-phosphate may provide benefits in terms of radiographic parameters and complication rates; however, more stringent research methodology is necessary to determine the extent of the benefit.
