Project description:Determining the incidence and causes of craniodental damage in wild carnivores is often constrained by limited access to specimens with associated ecological data, such as prey type and abundance. We assessed dental condition and cranial injuries in lion, leopard, and spotted hyena in relation to prey and predator populations in Zambia's Luangwa Valley, where large prey are more abundant and lion and leopard more numerous, and the Greater Kafue Ecosystem, where smaller prey species are more prevalent and lion and leopard less common. In Luangwa, lions had significantly higher rates of tooth fracture, and blunt trauma injuries attributable to prey-handling, compared to Kafue lions. In contrast, leopards in both regions had similar rates of tooth wear and breakage. Overall, lions showed a significantly higher tooth fracture rate than leopards on a per tooth basis. Spotted hyenas had the highest rates of tooth wear and fracture among all three carnivores, and greatly exceeded previously recorded rates based on historical samples. Despite larger numbers of lion and leopard in Luangwa, there was no difference in incidence of intraspecific injuries between regions. These results are consistent with a greater abundance of large prey species, especially buffalo, in the diets of Luangwa lions, and previous work showing a reliance on smaller prey species in Kafue throughout the large carnivore guild.

Project description:Isolated radial head fractures are rare and comprise about 2% of all fractures around the elbow. Bilateral radial head fractures are even rarer and few cases have been reported. We present a case of bilateral elbow effusion in a 28-year-old male patient. An initial diagnosis of inflammatory arthritis was made but on investigation it turned out to be a case of bilateral radial head fracture. The patient was managed conservatively with 10 days of immobilisation in above elbow slab followed by active elbow range of movement exercises. On follow-up at 6 months, the patient had near normal range of movements without pain or elbow instability.

Project description:ObjectiveThe aim of this study was to evaluate the intra- and interobserver variation of two classification systems for radial head fractures (Mason and Charalambous classifications) using plain radiographs.Material and methodsFive observers classified 30 radial head fractures as per the two classifications using anteroposterior and lateral elbow radiographs. Assessments were done on two occasions, at least 6 weeks apart.ResultsThe interobserver and intraobserver variation of the Mason classification showed fair (mean kappa = 0.33) and moderate agreement (mean kappa = 0.43) respectively. The interobserver and intraobserver variation of the Charalambous classification showed moderate agreement for both (mean kappa = 0.42 and 0.49 respectively). A greater proportion of radial head fractures could be classified using the Charalambous classification compared with the Mason classification (P < 0.001). With the Charalambous classification, the inter-observer variation was better when assessing fracture morphology (4 morphology groups) versus fracture displacement (2 displaced/un-displaced groups) (p = 0.010).ConclusionsThe Mason and Charalambous classifications for radial head fractures confer similar reliability when using plain radiographs, but the latter allows a greater proportion of fractures to be classified. Raters may agree more on fracture morphology as compared to fracture displacement. Our findings also demonstrate the limitations of using plain radiographs in classifying radial head fractures for clinical or research purposes, and suggest that evaluation with more sensitive modalities such as Computed Tomography may be preferable.

Project description:ImportanceAs cell phones gain more influence in daily life, they also become potentially more hazardous. Injuries resulting from cell phone use have long been reported largely in the context of driving-related incidents, but other mechanisms of injury have been underreported.ObjectiveTo assess the incidence, types, and mechanisms of head and neck injuries associated with cell phone use.Design, setting, and participantsRetrospective cross-sectional study using data from a national database of individuals with head and neck injuries related to cell phone use who presented to emergency departments in the United States between January 1998 and December 2017.Main outcomes and measuresIncidence, types, and mechanisms of injury related to cell phone use in the US population.ResultsA reported total of 2501 patients (1129 [55.0%] female, 795 [38.8%] white, and 772 [37.6%] aged 13-29 years) presented with injuries of the head and neck related to cell phone use; the estimated weighted national total was 76 043 patients (42 846 females [56.3%], 34 894 [45.9%] white, and 29 956 [39.4%] aged 13-29 years). The most commonly reported subsites of injuries in the head and neck region included the head (33.1% of estimated total); face, including eyelid, eye area, and nose (32.7%); and neck (12.5%). The most common injury diagnoses included laceration (26.3% of estimated total), contusion/abrasion (24.5%), and internal organ injury (18.4%). Age group distributions showed that most injuries associated with cell phone user distraction occurred among individuals aged 13 to 29 years (60.3%; Cramer V = 0.29). In addition, those younger than 13 years were significantly more likely to sustain direct mechanical injury from a cell phone (82.1%) than to have a cell phone use-associated injury (17.9%) (Cramer V = 0.305), whereas a cell phone use-associated injury was more likely than a direct mechanical injury to occur among those aged 50 to 64 years (68.2% vs 31.8%; Cramer V = 0.11) and those older than 65 years (90.3% vs 9.7%; Cramer V = 0.29).Conclusions and relevanceCell phone-related injuries to the head and neck have increased steeply over the recent 20-year period, with many cases resulting from distraction. Although the disposition of most cases is simple, some injuries bear a risk of long-term complications. Many of these injuries occurred among those aged 13 to 29 years and were associated with common activities, such as texting while walking. These findings suggest a need for patient education about injury prevention and the dangers of activity while using these devices.

Project description:ObjectiveComplex elbow fractures are common injuries in young adults. Results in recent studies with various operative treatment protocols are equivocal. We compared the results of radial head arthroplasty, excision with osteosynthesis in such injuries at two follow-ups 1 year apart.MethodsThirty-five patients of complex elbow fracture-dislocations including, posterior/anterior olecranon dislocation of elbow, terrible triad injury, anteromedial facet of coronoid fracture, Type IV Monteggia fracture-dislocation and unclassified elbow dislocation were enrolled. They were managed operatively by standardized protocol similar to McKee et al. radial head reconstruction with miniplates, lag screws or non-operative treatment for undisplaced fractures. Arthroplasty of radial head with cemented prosthesis + LCL repair with suture anchor/transosseous tunnel was done. Coronoid and olecranon fixation was always performed. Patients were evaluated as follows: Q-DASH score, MEPI, pain according to VAS, range of motion, complications and radiographic findings and fracture union, and elbow instability.ResultsThe mean length of follow-up among the patients was 18 months. There were statistically significant differences between the DASH score/MEPS between radial head excision and replacement/reconstruction. Instability was significantly reduced in those with LCL reconstruction. Excising the comminuted radial head without replacement had the worst outcome. Best PROM was reported in patients with osteosynthesis.ConclusionProvided a standard protocol is applied, radial head osteosynthesis has preferable outcomes in terms of patient-related outcomes as compared to arthroplasty, although not statistically significant. Radial head excision though has acceptable outcomes but there is a restriction of movements especially flexion-extension. Acceptable rate of complications major or minor warrants need of secondary surgical procedures or a staged treatment.

Project description:IntroductionWe report the case of volar dislocation of the ulnar head occurred after osteosynthesis for the treatment of distal radius fracture.Presentation of caseThe patient, 68-year-old female, had the dorsal displaced left distal radius fracture and volar dislocation of the ulnar head. Osteosynthesis was performed using a volar locking plate without postoperative immobilization. Two weeks after surgery, volar dislocation of the ulnar head in distal radioulnar joint (DRUJ) was noted on CT. Re-operation, triangular fibrocartilage complex (TFCC) was sutured to the ulnar fovea using a suture anchor, was performed in order to stabilize DRUJ. At 24 months after surgery, left wrist joint pain and the range of motion have improved, and the Mayo wrist score was excellent.DiscussionBased on the fact that the radius was fractured and the ulna was dislocated in DRUJ at the time of injury, the present case may have been a Galeazzi fracture.ConclusionWhen distal radius fracture is complicated by ulnar instability of DRUJ, active repair of the TFCC function may be necessary to prevent residual postoperative instability.

Project description:BackgroundRadial nerve palsy associated with fractures of the shaft of the humerus is the most common nerve lesion complicating fractures of long bones. However, the management of radial nerve injuries associated with humeral fractures is debatable. There was no consensus between observation and early exploration.Methods and findingsThe PubMed, Embase, Cochrane Central Register of Controlled Trials, Google Scholar, CINAHL, International Bibliography of the Social Sciences, and Social Sciences Citation Index were searched. Two authors independently searched for relevant studies in any language from 1966 to Jan 2013. Thirty studies with 2952 humeral fractures participants were identified. Thirteen studies favored conservative strategy. No significant difference between early exploration and no exploration groups (OR, 1.03, 95% CI 0.61, 1.72; I(2)?=?0.0%, p?=?0.918 n.s.). Three studies recommend early radial nerve exploration in patients with open fractures of humerus with radial nerve injury. Five studies proposed early exploration was performed in high-energy humeral shaft fractures with radial nerve injury.ConclusionsThe conservative strategy was a good choice for patients with low-energy closed fractures of humerus with radial nerve injury. We recommend early radial nerve exploration (within the first 2 weeks) in patients with open fractures or high-energy closed fractures of humerus with radial nerve injury.

Project description:In chronic radial head dislocation cases, the radial head may enlarge and become dome-shaped. To date, there is no validated tool to quantify radial head deformation and predict its influence on surgical outcomes. This study assesses the potential value of volume and surface calculations obtained by quantitative three-dimensional computed tomography scanning (Q3DCT) in the workup for a corrective surgery in pediatric patients with missed Monteggia lesions. Ten consecutive pediatric patients with a missed Monteggia lesion were included (2012-2020). The volume and articular surface size of the radial head were calculated using Q3DCT, and a three-dimensional reconstruction of the articular surface relief was depicted in a heat map. The head-neck ratio was calculated and compared to Q3DCT data of missed Monteggia patients and their age-/sex-matched controls. The radial head volume and radial articular surface size did not differ significantly between patients with missed Monteggia lesions and age-/sex-matched controls (volume 1487 mm3 vs. 1163 mm3, P = .32; articular surface size 282 mm3 vs. 236 mm3, P = .33). Optically, heat maps of the articular surface of missed Monteggia patients did not differ notably from control heat maps. A higher head-neck ratio correlated to a larger radial head volume (Pearson r = 0.73; P = .2). Q3DCT may be an interesting tool in the preoperative workup of pediatric missed Monteggia lesions. Prospective research with larger cohort sizes and data that compares the affected side to the contralateral elbow is needed to assess its true clinical potential.

Project description:Displaced radial head fractures are treated with open reduction and internal fixation using implants. Failure of fixation may occur in the presence of comminution and in multifragmentary fractures; open surgical approaches are necessary for removal of the implants and radial head resection. Arthroscopic radial head resection has been described as a minimally invasive and effective treatment for failed radial head fracture fixation; however, periarticular adhesions and prominent implants add to the complexity and technical difficulty of the procedure. The described technique uses 3 portals for adhesiolysis, implant removal, and radial head resection. Resection is performed in stages; smaller-diameter instruments are used to gain and improve access, and larger resectors are used subsequently. Adequacy of resection is assessed arthroscopically and with biplanar imaging. The arthroscopic technique avoids the need for an open surgical approach and prevents subsequent morbidity. In addition, the rehabilitation time is shorter and patient satisfaction is high.

Project description:Botulism developed in a patient following surgical repair of an open radial fracture. Symptoms resolved after treatment with antitoxin and antibiotics, and hardware excision was deferred. Subsequent osteomyelitis necessitated hardware exchange, and wound cultures grew Clostridium argentinense. This case highlights the management of botulism associated with orthopedic hardware.
