Aims. Low-energy distal radius fractures (DRFs) are the most common upper arm fractures correlated with bone fragility. Vitamin D deficiency is an important risk factor associated with DRFs. However, the relationship between DRF severity and vitamin D deficiency is not elucidated. Therefore, this study aimed to identify the correlation between DRF severity and serum 25-hydroxyvitamin-D level, which is an indicator of vitamin D deficiency. Methods. This multicentre retrospective observational study enrolled 122 female patients aged over 45 years with DRFs with extension deformity. DRF severity was assessed by three independent examiners using 3D CT. Moreover, it was categorized based on the AO classification, and the degree of articular and volar cortex comminution was evaluated. Articular comminution was defined as an articular fragment involving three or more fragments, and volar cortex comminution as a fracture in the volar cortex of the distal fragment. Serum 25-hydroxyvitamin-D level, bone metabolic markers, and bone mineral density (BMD) at the lumbar spine, hip, and wrist were evaluated six months after injury. According to DRF severity, serum 25-hydroxyvitamin-D level, parameters correlated with bone metabolism, and
Aims. To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour. Methods. A total of 40 patients suffering from non-rheumatoid wrist arthritis were enrolled in a randomized controlled trial comparing the ReMotion and Motec TWAs. Patient-rated and functional outcomes, radiological changes, blood metal ion levels, migration measured by model-based radiostereometric analysis (RSA), bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), complications, loosening, and revision rates at two years were compared. Results. Patient-Rated Wrist and Hand Evaluation (PRWHE) scores, abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) scores, and pain improved similarly and significantly in both groups. Wrist motion improved significantly in the Motec group only, and forearm rotation in the ReMotion group only. Cobalt (Co) and chromium (Cr) blood ion levels were significantly higher in the metal-on-metal (MoM) Motec group than in the metal-on-polyethylene (MoP) ReMotion group. Mean total translation was 0.65 mm (95% confidence interval (CI) 0.26 to 1.12) and 0.27 mm (95% CI 0.14 to 0.47) for the ReMotion carpal and radial components, and 0.32 mm (95% CI 0.22 to 0.45) and 0.26 mm (95% CI 0.20 to 0.34) for the Motec metacarpal and radial components, respectively. Apart from dorsal and volar tilts, which were significantly higher for the radial ReMotion than for the Motec component, no significant differences in absolute migration occurred.
There is ambiguity surrounding the degree of scaphoid union required to safely allow mobilization following scaphoid waist fracture. Premature mobilization could lead to refracture, but late mobilization may cause stiffness and delay return to normal function. This study aims to explore the risk of refracture at different stages of scaphoid waist fracture union in three common fracture patterns, using a novel finite element method. The most common anatomical variant of the scaphoid was modelled from a CT scan of a healthy hand and wrist using 3D Slicer freeware. This model was uploaded into COMSOL Multiphysics software to enable the application of physiological enhancements. Three common waist fracture patterns were produced following the Russe classification. Each fracture had differing stages of healing, ranging from 10% to 90% partial union, with increments of 10% union assessed. A physiological force of 100 N acting on the distal pole was applied, with the risk of refracture assessed using the Von Mises stress.Aims
Methods
There is no level I evidence dealing with the optimal period of immobilization for patients with a displaced distal radial fracture following closed reduction. A shorter period might lead to a better functional outcome due to less stiffness and pain. The aim of this study was to investigate whether this period could be safely reduced from six to four weeks. This multicentre randomized controlled trial (RCT) included adult patients with a displaced distal radial fracture, who were randomized to be treated with immobilization in a cast for four or six weeks following closed reduction. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after follow-up at one year. Secondary outcomes were the abbreviated version of the Disability of Arm, Shoulder and Hand (QuickDASH) score after one year, the functional outcome at six weeks, 12 weeks, and six months, range of motion (ROM), the level of pain after removal of the cast, and complications.Aims
Methods
We performed a retrospective study to determine
the effect of osteoporosis on the functional outcome of osteoporotic
distal radial fractures treated with a volar locking plate. Between
2009 and 2012 a total of 90 postmenopausal women with an unstable
fracture of the distal radius treated with a volar locking plate
were studied. Changes in the radiological parameters of 51 patients
with osteoporosis (group 1, mean age 66.9, mean T-score –3.16 ( We found that osteoporosis does not have a negative effect on
the functional outcome and additional analysis did not show a correlation
between T-score and outcome. Cite this article:
The osteoinductive properties of demineralised
bone matrix have been demonstrated in animal studies. However, its therapeutic
efficacy has yet to be proven in humans. The clinical properties
of AlloMatrix, an injectable calcium-based demineralised bone matrix
allograft, were studied in a prospective randomised study of 50
patients with an isolated unstable distal radial fracture treated
by reduction and Kirschner (K-) wire fixation. A total of 24 patients
were randomised to the graft group (13 men and 11 women, mean age
42.3 years (20 to 62)) and 26 to the no graft group (8 men and 18
women, mean age 45.0 years (17 to 69)). At one, three, six and nine weeks, and six and 12 months post-operatively,
patients underwent radiological evaluation, assessments for range
of movement, grip and pinch strength, and also completed the Disabilities
of Arm, Shoulder and Hand questionnaire. At one and six weeks and
one year post-operatively, bone mineral density evaluations of both
wrists were performed. No significant difference in wrist function and speed of recovery,
rate of union, complications or bone mineral density was found between
the two groups. The operating time was significantly higher in the
graft group (p = 0.004). Radiologically, the reduction parameters
remained similar in the two groups and all AlloMatrix extraosseous leakages
disappeared after nine weeks. This prospective randomised controlled trial did not demonstrate
a beneficial effect of AlloMatrix demineralised bone matrix in the
treatment of this category of distal radial fractures treated by
K-wire fixation. Cite this article:
