BackgroundOccupation-based intervention (OBI) in hand therapy has shown superior benefits in patient-reported performance and physical measures; however, only a few studies have used OBI. We developed a decision-aid to promote the use of an injured hand in the real world (Aid for Decision-making in Occupation Choice for hand; ADOC-H)PurposeTo investigate the clinical utility of the ADOC-H (paper version) in patients with distal radius fractures.Study DesignA prospective case series and a clinical survey for occupational therapists.MethodsThis study comprised a prospective patient case series of 8 patients with distal radius fractures, treated using Volar locking plates, and a clinical survey of 4 experienced occupational therapists.ResultsNo patient or therapist complaints or drop-outs were reported. Active range of motion (wrist), Grip strength, and Disabilities of the Arm, Shoulder, and Hand scores improved for all patients. The ADOC-H induced 158 activities using the injured hand, with activities of daily living (69.8%) selected earlier in the treatment period, and instrumental activities of daily living (63.3%) selected later. The feedback and case studies suggested that the ADOC-H was useful for patients who were afraid of using the hand and, interestingly, patients who were able to use their hand without pain or other problems. The clinical survey showed that most therapists found the ADOC-H effective in facilitating real-life use of an injured hand.ConclusionsThe ADOC-H paper version is an useful tool that can be applied to facilitate patients with distal radius fractures to use their injured hands in real-life settings. 相似文献

PurposeTibial tubercle/tuberosity fractures are rare injuries in young patients accounting for less than one percent of physeal fractures. Bilateral simultaneous fractures are even rarer, with only a few case reports in literature. The purpose of our study was to describe the largest case series of bilateral simultaneous tibial tuberosity avulsion fractures and compare it with unilateral fractures. We also wanted to compare our bilateral fractures case series with all the cases reported in the last 65 years.MethodsIRB approved retrospective study involving patients under age 18 years with tibial tuberosity avulsion fractures. Bilateral simultaneous fractures were compared to a unilateral group including demographic data, mechanism of injury, clinical exam findings, complication rates, and outcomes including return to function. Statistical analysis was performed using Mann-Whitney and Fisher Exact tests to compare the different groups.Results138 patients (131 males, 7 females) from a tertiary children’s hospital between 2012 and 2019 with tibial tuberosity avulsion fractures were included. 11 bilateral simultaneous fractures (BL Group) were identified and compared to age matched cohort from the 127 unilateral fracture patients (UL group). There was no significant difference found in BMI, height, weight, age, sex, mechanism of injury, return to functional range of motion, and return to sports between the groups. 7/11 (63%) of the patients in the BL group who sustained simultaneous fractures had to be home bound and could not attend school for an average of 8.3 weeks. There was a higher rate of complications in the BL group (63.3%) compared to the UL group (21.1%), which was statistically significant. The most common complications in the bilateral group were hardware removal and wound dehiscence.ConclusionThis first case series comparing unilateral versus bilateral simultaneous tibial tuberosity avulsion fractures suggests that the final outcomes of the two groups are similar, however it shows a significantly higher complication rate and hardware removal rate in the BL group. This study is also the first to highlight the significant initial morbidity in the BL fracture group with issues with regards to early mobility and loss of school-days. Keeping in mind the profound initial impact the bilateral injury poses to the patient; surgeons can possibly plan for rigid fixation for early mobilization to better prepare bilateral fracture patients for the early post-operative recovery process. 相似文献

Total elbow arthroplasty as a treatment option for open elbow fracture is relatively rare described. We reported a 39 years old polytrauma patient with complex open elbow fracture (Gustilo-Anderson type IIIB). The patient presented with large soft tissues defect on dorsal part of the left elbow, ulnar palsy due to the irreparable loss of the ulnar nerve, distal triceps loss due to the complete loss of the olecranon, loss of both humeral condyles with collateral ligaments and complex elbow instability. Only few similar cases have been published. Reconstructive surgery included repetitive radical debridement, irrigation, vacuum assisted closure system therapy, external fixation, coverage of the soft tissue defect with fascia ecutaneous flap from the forearm. Four months after the injury, total elbow arthroplasty with autologous bone graft (from the proximal radius) inserted in the ulnar component, was performed. At 3 years postoperatively, the patient is able to perform an active flexion from 0 to 110 with full pronosupination. Only passive extension is allowed. The ulnar neuropathy is persistent. Patient has no signs of infection or loosening of the prosthesis. 相似文献

BackgroundOur aim in this study was to identify the fibular footprint of the Anterior Inferior Tibiofibular Ligament (AITFL) and its relation to Wagstaffe fracture fragment size.MethodsWe examined 25 cadaveric lower limbs which were carefully dissected to identify the lateral ankle ligaments. The AITFL anatomy was compared to 40 Wagstaffe fractures identified from our ankle fracture database.ResultsThe AITFL origin was from the anterior fibular tubercle with an average length of 21.61 mm (95% CI 20.22, 22.99). The average distance of the distal aspect of the AITFL footprint to the distal fibula margin was 11.60 mm (95% CI 10.49, 12.71). In the ankle fractures analyzed, the average length of the Wagstaffe fragment was 17.88 mm (95% CI 16.21, 19.54). The average distance from the distal tip of the fibula to the Wagstaffe fracture fragment was 21.40 mm (95% CI 19.78, 23.01).In total there were 22 syndesmosis injuries. There was no statistical difference in Wagstaffe fragment size between stable and unstable groups.ConclusionThe AITFL fibular origin was both larger and more distal than the Wagstaffe fracture fragments seen in our institution. Therefore, this suggests that a ligamentous failure will also have to occur to result in syndesmotic instability. The size of fracture fragment also did not confer to syndesmotic instability on testing.Level of Evidence - 3 相似文献

PurposeCompletely displaced distal radius fractures in children have been traditionally reduced and immobilized with a cast or pin fixed. Cast immobilization leaving the fracture displaced in the bayonet position has been recently suggested as a non-invasive and effective treatment alternative. This is a pilot comparative study between reduction and no reduction.MethodsWe assessed subjective, functional and radiographic outcome after a minimum 2.5-year follow-up in 12 children under ten years of age who had sustained a completely displaced metaphyseal radius fracture, which had been immobilized leaving the fracture in an overriding position (shortening 3 mm to 9 mm). A total of 12 age-matched patients, whose similar fractures were reduced and pin fixed, were chosen for controls. ResultsAt follow-up none of the 24 patients had visible forearm deformity and the maximal angulation in radiographs was 5° Forearm and wrist movement was restored (< 10° of discrepancy) in all 24 patients. Grip strength ratio was normal in all but three surgically treated patients. All patients had returned to their previous activities. One operatively treated boy who was re-operated on reported of pain (visual analogue scale 2).ConclusionThe results of this study do not demonstrate the superiority of reduction and pin fixation over cast immobilization in the bayonet position of closed overriding distal metaphyseal radius fractures in children under ten years with normal neurovascular findings.Level of evidenceIII 相似文献

BackgroudPatients experiencing acute trauma have limited time for their involvement in shared decision making, which may lead to decisional conflict. The purpose of this study was to evaluate whether providing audiovisual surgical information can reduce decisional conflict when deciding between surgical and nonsurgical treatment in patients with distal radius fractures (DRFs) and to evaluate factors that may affect decisional conflict.MethodsWe prospectively enrolled 50 consecutive patients who presented with acute DRFs and chose to undergo surgery, for which volar plate fixation was recommended. We randomized these patients into 2 groups. The test group was given a video clip of audiovisual surgical information in addition to regular information while the control group was only given regular information. The video clip consisted of the purpose, procedure, and effect of the surgery, precautions and complications after the operation, and other treatment options that could be performed if operation was not performed. At 2 weeks after the surgery, we evaluated patients'' decisional conflict using a decisional conflict scale (DCS). In addition, we evaluated factors that might affect decisional conflict, such as age, dominant hand, comorbidities, history of previous operations, perceived disability, and provision of the video clip.ResultsThe test group showed significantly lower DCS scores than the control group (19.6 vs. 32.1, p = 0.001). In multivariate analysis, younger age and provision of the video clip were associated with lower DCS scores.ConclusionsThis study has demonstrated that providing information through audiovisual media such as video clips could reduce decisional conflict in patients who chose to undergo plate fixation for DRFs. This study also suggests that older patients may need more careful doctor-patient communication as they have more decisional conflict than younger patients. 相似文献
