Unlabelled:
Our purpose was to assess the impact of a secondary prevention program for osteoporotic fractures in patients with fragility fracture and to determine its effect on long-term compliance with bisphosphonate treatment. Persistence with bisphosphonate use was 71%. Attending follow-up visits was the only variable significantly associated with adherence to bisphosphonates.
Introduction:
The aim of this study is to assess the impact a secondary prevention program for osteoporotic fractures in a prospective cohort of patients with at least one fragility fracture and to determine the effect of this intervention on long-term compliance with bisphosphonate treatment.
Methods:
All patients older than 50 years with a fragility fracture attended at the emergency department over a 2-year period were appointed for a clinical visit through a telephone call. Two follow-up controls at 4 and 12 months were scheduled. After a mean of 4 years, a telephone survey was conducted to assess compliance with treatment.
Results:
Of 683 eligible patients, 380 (55.6%) were visited at the hospital. Previous treatment with bisphosphonates was recorded in 17.9% of patients. DXA scan was considered normal in 61 patients and revealed osteopenia in 184 and osteoporosis in 135. Pharmacological treatment was indicated in 90% of patients (alendronate in 76%). Among 241 patients who participated in the survey, eight patients had new fractures (four were on treatment with bisphosphonates and four had discontinued treatment). Of 187 patients in which bisphosphonates were prescribed at the initial visit, 133 (71.1%) continued using bisphosphonates. Attendance of scheduled visits was associated with adherence to bisphosphonates (odds ratio, 3.33; 95% confidence interval, 2.99-3.67).
Conclusions:
The efficacy of the program to recruit patients was 55%. In patients visited at the hospital, treatment with bisphosphonates increased from 17.9% to 76%. Persistence with bisphosphonate use after a mean of 4 years was 71%. Attending follow-up visits was significantly associated with adherence to bisphosphonates.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
