Background: Identifying and treating patients with fragility fractures may be effective in prevention of subsequent fractures because a first fragility fracture often predicts a second fracture.

Objectives: To evaluate a multidisciplinary anti-osteoporotic clinic for patients with prior distal radius fragility fractures (DRFF). To assess whether addressing this early fracture may prevent a second fracture.

Methods: A retrospective case-control study was performed. Cases included patients treated surgically for DRFF who were assessed at a tertiary, multidisciplinary, fracture-prevention clinic. Controls were a series of similarly treated patients who did not attend the clinic. The primary outcome measure was a second fracture.

Results: Average follow-up was 42 months for the treated group and 85 months for the untreated group. The treated group received more treatment for osteoporosis than controls; however, despite one new fracture in the treated group and six new fractures in the control group, there was no significant difference in fracture occurrence.

Conclusions: This pilot study supports the effectiveness of our multidisciplinary anti-osteoporotic clinic in treating osteoporosis but not in reducing subsequent fractures. Further study with larger cohorts and longer follow-up is needed to improve our ability to implement effective prevention of fragility fractures.

Because fragility fractures have an enormous impact on the practice of medicine and global health systems, effective screening is imperative. Currently, dual-energy X-ray absorptiometry (DXA), which has limited ability to predict fractures, is being used. We evaluated the current literature for a method that may constitute a better screening method to predict fragility fractures. A systematic review of the literature was conducted on computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound to evaluate screening methods to predict fragility fractures. We found that ultrasound had sufficient data on fracture prediction to perform meta-analysis; therefore, we analyzed prospective ultrasound cohort studies. Six study populations, consisting of 29,299 individuals (87,296 person-years of observation) and including 992 fractures, were analyzed. MRI was found to be sensitive and specific for osteoporosis, but its use for screening has not been sufficiently evaluated and more research is needed on cost, accessibility, technical challenges, and sensitivity and specificity. CT could predict fracture occurrence; however, it may be problematic for screening due to cost, exposure to radiation, and availability. Ultrasound was found to predict fracture occurrence with an increased risk of 1.45 (95% confidence interval 1.21–1.73) to fracture. Ultrasound has not replaced DXA as a screening tool for osteoporosis, perhaps due to operator-dependency and difficulty in standardization of testing.

Background: Fractures of the distal radius are the most common fractures in the upper extremity, and their incidence is increasing with the aging of the population. Despite anatomical reduction of the bones, many patients complain of residual pain. A reason for this may be ligament injury not addressed during surgery or conservative treatment. Radiographic measurements may allow assessment of ligament integrity but they may be population specific and differ among races.

Objectives: To assess radiographic wrist measurements in an Israeli population and to compare them to existing values.

Methods: Demographic data, previous diagnosis of osteoporosis, fracture classification, and radiologic measurements (radial height, radial inclination, ulnar variance, volar tilt, and d2/w2) were measured and compared.

Results: The study was comprised of 53 females and 27 males, mean age 64 years, with wrist radiographs following surgery. Of these, 13% were smokers and 38.5% had osteoporosis. According to the Arbeitsgemeinschaft für Osteosynthesefragen classification system, most of the fractures were comminuted and intra-articular. The mean values for all measurements did not differ significantly from values in the literature. The average d2/w2 ratio (describing the radiocarpal ligaments) was 0.42, significantly differing from this measurement in normal wrists as described in the literature, but similar to a population following surgery (P = 0.002).

Conclusions: Our population had more fragility fractures than other populations. Otherwise, our demographics and measurements did not differ from normal values described in the literature. This study supports the validity of any wrist radiographic study performed in our population.
