Strontium Ranelate in the Healing of Fractures Complicated with Delayed Union. It is Really Effective?

Abstract

Osteoporosis is a systemic skeletal disease characterized by low bone strength, which leads to an increased risk of fracture. The primary objective of osteoporosis treatment is the prevention of fragility fractures and the secondary objective is their rapid healing if they occur. Strontium ranelate is an antiosteoporotic therapeutic agent with a double action mechanism: the increase of bone formation and the decrease of bone resorption, contributing thus to the improvement of bone healing. Preclinical studies have demonstrated the efficacy of strontium ranelate for the improvement of bone healing and bone microarhitecture, as well as of the osteointegration of implants. Some clinical cases have been reported regarding the efficacy of strontium ranelate in the healing of long bone fractures complicated by nonunion or delayed union. In the present study we have reported 2 clinical cases that demonstrate the effectiveness of the treatment with strontium ranelate (Osseor) for 3-6 months in the healing of complicated long bone fractures with delayed union. Our cases confirm the results of the open label study CL3-12911-036 (delayed union and non-union fracture study), where the treatment with 2 g/day of strontium ranelate improved healing and led to a better quality of life. Even if there are some cardiovascular contraindications, strontium ranelate is proven to reduce vertebral and non-vertebral fracture risk in osteoporosis and in the same time improves bone microarchitecture and accelerates fracture healing.

Correlations Between Heparinated Blood Glucose Determined with Automatic Analyzers and the Severity of the Acute Coronary Disease

“…Our results are similar to those of other previous studies. The FREEDOM trial, probably the biggest study evaluating diabetic patients with multivessel disease, osteoporosis and increased tendency to multiple fractures, at any level of the bone system, pointed out that most patients had very extensive disease, requiring surgical treatment, which had better results than interventional treatment [9][10][11].…”

Management of Collapse Tibial Plateau Fractures Using a Hydroxyapatite-Tricalcium Phosphate Ceramic(ATLANTIK�) and Plate Osteosynthesis

“…In difficult cases, primary total knee arthroplasty has potential advantages for elderly patients, while it can be technically challenging in younger patients [42,43]. The management of bone defects associated with comminution and osteoporosis represents a great challenge in clinical practice [12,38,44]. Bone grafting (autografts, allografts and synthetic substitutes) is an important treatment for bone defects while successful incorporation of grafted biomaterial into bone defects requires the ability and performance of material to promote new bone formation and provide a scaffold for osteogenesis [25,45].…”

Hemiarthroplasty in Complex Proximal Humeral Fractures Is uncemented methaphyseal corundum blasted titanium humeral stem an efficent alternative?

“…In case of 4-parts fractures of the proximal humerus, the results are influenced by many factors: age of the patient, quality of bone [26], the moment when the surgical intervention took place, deficiencies in the surgical technique, post-surgical complications, post-surgical rehabilitation [5,27,28]. A favorable and functional prognosis can be anticipated for a younger patient without pre-surgical neurological deficit or post-surgical complications and with a satisfactory aspect of the shoulder after 6 weeks.…”
