The purpose of this clinical study was to evaluate and compare the effectiveness of ultrasound (US)-guided platelet-rich plasma (PRP) injections versus US-guided corticosteroid injections (CSI) in the treatment of greater trochanteric pain syndrome (GTPS). Methods Between January 2015 and December 2016, 24 patients with GTPS were enrolled and randomized in two groups (A and B). Group A (study group) patients received US-guided PRP injection treatment, while group B (control group) patients received US-guided CSI treatment. Clinical outcomes in both groups were evaluated and compared using the Visual Analogue Scale (VAS) of pain, the Harris Hip Score (HHS) and the presence or absence of complications at 4, 12, and 24 weeks post-injection. The level of significance was set at p<0.05. Results Both groups showed improved scores (VAS and HHS) compared to the pre-injection period, but patients in group A had a statistically significant (p <0.05) decrease in VAS score and a significantly increased HHS at the last follow-up (24 weeks post-injection). No complications were reported.
Nitrogen-containing bisphosphonates (N-BPs) are pharmaceutical agents that have been used for many years to treat osteoporosis, multiple myeloma, Paget's disease, metastatic bone disease, and a variety of other diseases in which bone mineral density is reduced. Given that N-BPs inhibit bone resorption, an important stage in the fracture healing process, they have been extensively studied in preclinical models for their activity. In animal models, treatment with N-BPs is associated with a larger callus formation in fracture area and delay in remodeling from primary woven bone to lamellar bone, but there is no delay in formation of the fracture callus. In humans, all existing evidence suggest that initiating treatment with N-BPs, after upper and lower limb fractures, does not appear to have a significant effect on fracture healing. Rarely, patients with long-term use of N-BPs may develop “atypical fractures” and delay in their healing. Therefore, this clinical condition is not fully understood and many questions remain unanswered. Similarly, there are few studies about the benefits of stopping a long-term treatment with them, if a fracture occurs. Although most studies support that chronic N-BP therapy may lead to fracture healing delay, this is not fully documented. On the other hand, there are studies that are in complete disagreement with them. All of the above suggest that there is a need for more detailed future research into larger patient populations and different types of fractures, with sufficient data on the type, dosage, route and duration of administration of N-BPs, and the control methods of fracture healing, in order to have a safe final conclusion on the effect of their long-term administration in this highly complex process.
Osteobridge is an excellent knee arthrodesis system, which is preferable to other methods in case of resection of the distal femur along with the failure of the knee extensor mechanism.
The success of Pavlik harness therapy is based, among other things, upon the correct reapplication by parents. This prospective study assesses the effectiveness of a validated Objective Structured Assessment of Technical Skill (OSATS) educational module for Pavlik harness application among Greek parents. Methods: Forty consecutive parents of newborns with developmental dysplasia of the hip (DDH), who were treated with Pavlik harness, were divided into two groups. Twenty parents (group 1) were educated with the Greek OSATS version, while the rest (group 2) served as the control. The OSATS score, quality of the final product (Global Rating Scale -GRS) and sonographic imaging of the hips were evaluated during follow-up. Results: Post-intervention evaluation revealed significant higher means of OSATS score (p<0.01), GRS of performance (p<0.05) and GRS of final product (p<0.05) for group 1. At every retention time point, OSATS was significantly higher for group 1, however there were no significant differences between either GRS score between groups. There was no significant difference in radiographic evaluation and successful outcome. Conclusions: This educative module increased the parents' skill level on application of Pavlik harness. However, this module revealed no significant effect in clinical and radiological evaluation of the hips, in this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
