Complications in Distal Radius Fracture
Study Details
Study Description
Brief Summary
BACKGROUND. Distal radius fractures (FRD) are up to 17% of all diagnosed fractures and are the most commonly treated fractures in adult orthopedic patients. The management could be either conservative or surgical, depending on AO bone fracture classification. The principles of good treatment involves an anatomical reduction with a proper immobilization that keep the reduction.
OBJECTIVE. Determine if percutaneous pinning for six weeks versus three has major complications in distal radius fractures.

Detailed Description
Distal radius fractures (DRF) are up to 20% of all diagnosed fractures and are the most commonly treated fractures in adult orthopedic patients. DRF occur in distal third of the radius bone, located less than 2.5 cm from the radiocarpal joint. In general, it is the result of a fall on the hand in extension. A bimodal distribution is observed with a peak incidence predominantly in young adult patients and another peak in elderly women. In the younger population these fractures are usually the result of high-impact injuries such as vehicular accidents or high-altitude falls. This diagnosis in elderly most commonly occurs by falls from their own height and other low-energy trauma.
The management could be either conservative or surgical, depending on AO bone fracture classification. Regarding treatment, there is still much controversy as to what procedure would be ideal in each case. When selecting the therapeutic method, the patient's age, work, functional status and daily activities should be considered. Therapeutic alternatives differ considerably around the world and no technique has proven to be superior to all others, and there is no particular method that yields acceptable results in all types of DRF. The principles of good treatment involves an anatomical reduction with a proper immobilization that keep the reduction.
If segmental or unstable fractures are not treated properly, serious complications can occur. The rate of complications reported in the literature varies from 6 to 80% and these may be a consequence of the fracture or its treatment. There are many vital structures of soft tissue in close proximity to the bony anatomy around the wrist and the complications associated with these soft tissues may be more problematic than the fracture. Some surgical complications are loss of mobility, delayed consolidation, pseudoarthrosis, nerve compression, painful syndromes, complications of fixation material, osteomyelitis, vicious consolidation, tendon rupture, tenosynovitis, pathological scarring, radio-cubital synostosis, Dupuytren's contracture, arthritis and ligament injury. However, cutaneous complications such as ulcers or granulomas may occur at the site of nails, although not usually serious complications may prevent early rehabilitation of the patient and extend recovery times for incorporation into their daily activities.
Statistical analysis. The results will be reported in contingency tables, frequencies, percentages, measures of central tendency and dispersion. Qualitative variables will be analyzed with the chi-square statistic and quantitative variables with t-test for independent samples with a significance level of 95% with their respective confidence intervals, or with non-parametric statistics if necessary. Using a mean difference formula with a standard deviation of 5 and an expected magnitude of the differences of at least 4 points on the PRWE scale, with a confidence interval of 95%, a power β of 80%, with a statistically significant p = ˂0.05, adding 20% of error. A sample of 30 participants was obtained per group. For evaluation of pain (Visual Analogue Scale) and functional evaluation (Patient Rated Wrist Evaluation), the Student's T test and one-way ANOVA with Tuckey's post-hoc test will be performed for multiple comparisons in order to identify differences between groups. Statistical analysis will be performed with IBM SPSS version 20 (SPSS, Inc., Armon, NY).

Outcome Measures
Primary Outcome Measures
- Visual Analogue Scale [14 week]
It´s a numeric scale, when 0 value is equal to no pain; and 10 is equal to a maximum pain
Secondary Outcome Measures
- Patient Rated Wrist Evaluation (PRWE) [14 weeks]
It´s a 15- item questionnaire designed to measure wrist pain and disability in activities of daily living. developed in 1998 for clinical assessment and is used for specific wrist problems. It is one of the reliable upper extremity outcome instrument
- Wrist mobility [14 weeks]
Mobility in flexion, extension, pronation, supination, cubital and radial deviation using a goniometer.
- Grip strength [14 weeks]
Using a hydraulic dynamometer with the patient's elbow in 90 grades of flexion and forearm in neutral rotation.
- Skin condition [6 weeks]
Evaluation of skin condition and integrity, when normal is equal to 0, ulcer=1 and granuloma=2
