The Likelihood of an Occult Fracture in Skeletal Surveys Obtained in Children More Than 2 Years Old With Concerns of Physical Abuse.

OBJECTIVES: Skeletal surveys are necessary in the evaluation for physical abuse in children less than 2 years old, but when to obtain a skeletal survey in older children is less clear. METHODS: A retrospective study of patients older than 2 years who underwent skeletal survey over a 3-year period after implementation of an electronic health record physical abuse order set was conducted. Data were analyzed using descriptive statistics and compared with data from a cohort before order set implementation. The radiation dose of a skeletal survey in a 5-year old was calculated using a previously published technique. RESULTS: There were 325 skeletal surveys, a marked increase in the rate of skeletal surveys compared with before order set implementation. Less than 2% (6/325) of skeletal surveys demonstrated an occult fracture. Of the 6 patients with occult fractures, 4 were physically abused; in each case, the diagnosis of abuse was evident before the skeletal survey. The other 2 patients fell from windows. The radiation exposure was 0.34 mSv. CONCLUSIONS: The rate of occult fractures on skeletal survey is significantly lower than previously reported. This is likely because our population included all children who underwent skeletal survey and not the subset referred to a child abuse pediatrician. In addition, our data demonstrate that in children older than 2 years, skeletal surveys are unlikely to assist in making a diagnosis of physical abuse. The radiation exposure in a 5-year-old is 70% greater than in an infant, but still a dose, which represents a negligible health risk.

Pediatric tibial shaft and distal metaphyseal fractures.

OBJECTIVES: This study aims to investigate the effects of associated factors like age, fracture level, accompanying fibular fractures and wound condition on healing by determining and comparing union scores of pediatric tibial fractures (PTFs). PATIENTS AND METHODS: Forty-five patients with 46 PTFs (32 males, 13 females; mean age 9.5 years; range 2 to 16 years) who were treated by closed reduction and casting or operated between January 2016 and January 2019 were retrospectively evaluated. The union scores were evaluated at the end of fourth, sixth and eighth weeks and compared to each other. Effects of the age, associated fibular fractures, wound condition, fracture level and treatment type to union score were analyzed. RESULTS: Twenty-eight (60.9%) out of 46 PTFs had associated fibular fractures and 18 (39.1%) did not. Motor vehicle accident was the most frequent etiologic factor (47.8%). Thirty-four out of 46 fractures were closed tibial fractures (73.9%) and 12 had open wound (26.1%). There was a negative correlation between age and the union scores (p<0.001 for each week). No significant difference was observed between the union score of diaphyseal and metaphyseal fractures at the fourth, sixth, and eighth weeks. The union scores of each week were higher in the conservative group compared to operative group (p<0.001 for each week). Associated fibular fracture group had lower union scores compared to isolated tibial fracture group at fourth, sixth and eighth weeks. Likewise, the union scores of the open fracture group were lower than the closed fracture group (p<0.05 for each week). CONCLUSION: Associated fibular fractures, open fractures and aging negatively affect union scores of PTFs. Attention should be paid, particularly in these conditions, during the selection of the operation type and the follow-up period of PTFs.

Use of Advanced Imaging for Radiographically Occult Hip Fracture in Elderly Patients: A Systematic Review and Meta-Analysis.

Background The overall rate of hip fractures not identified on radiographs but that require surgery (ie, surgical hip fractures) remains unclear in elderly patients who are suspected to have such fractures based on clinical findings. Moreover, the importance of advanced imaging in these patients has not been comprehensively assessed. Purpose To estimate the frequency of radiographically occult hip fracture in elderly patients, to define the higher-risk subpopulation, and to determine the diagnostic performance of CT and bone scanning in the detection of occult fractures by using MRI as the reference standard. Materials and Methods A literature search was performed to identify English-language observational studies published from inception to September 27, 2018. Studies were included if patients were clinically suspected to have hip fracture but there was no radiographic evidence of surgical hip fracture (including absence of any definite fracture or only presence of isolated greater trochanter [GT] fracture). The rate of surgical hip fracture was reported in each study in which MRI was used as the reference standard. The pooled rate of occult fracture, diagnostic performance of CT and bone scanning, and strength of evidence (SOE) were assessed. Results Thirty-five studies were identified (2992 patients; mean age, 76.8 years ± 6.0 [standard deviation]; 66% female). The frequency of radiographically occult surgical hip fracture was 39% (1110 of 2835 patients; 95% confidence interval [CI]: 35%, 43%) in studies of patients with no definite radiographic fracture and 92% (134 of 157 patients; 95% CI: 83%, 98%) in studies of patients with radiographic evidence of isolated GT fracture (moderate SOE). The frequency of occult fracture was higher in patients aged at least 80 years (44%, 529 of 1184), those with an equivocal radiographic report (58%, 71 of 126), and those with a history of trauma (41%, 977 of 2370) (moderate SOE). CT and bone scanning yielded comparable diagnostic performance in the detection of radiographically occult hip fracture (P = .67), with a sensitivity of 79% and 87%, respectively (low SOE). Conclusion Elderly patients with acute hip pain and negative or equivocal findings at initial radiography have a high frequency of occult hip fractures. Therefore, the performance of advanced imaging (preferably MRI) may be clinically appropriate in all such patients. © RSNA, 2020 Online supplemental material is available for this article.

Prevalence and distribution of occult fractures on skeletal surveys in children with suspected non-accidental trauma imaged or reviewed in a tertiary Dutch hospital.

PURPOSE: The purpose of the study was to determine the rate of occult fractures (without clinical symptoms) per presenting clinical injury i.e., children presenting with a fracture, bruise, abusive head trauma and the types of fracture most likely to be found, in a series of infants and young children suspected of being victims of NAT. METHODS: Skeletal surveys done between 2008 and 2018 of children (< 5 years) were retrospectively analyzed. Both radiographs of admitted children and reassessment images from all over the country were included and reviewed by a forensic paediatric radiologist. Deceased children were excluded. Variables as gender, age, initial clinical injury and occult fractures were collected. Occult fractures on the follow-up skeletal survey were collected. RESULTS: A total of 370 skeletal surveys of 296 children were included. Median age was 22 weeks (IQR 11-48), there were 172 (58%) boys. A total of 195 occult fractures were detected in 111 (32%) children. Occult fractures were detected in 37/126 (29%) children with fracture as presenting symptom, 33/90 (37%) children with head trauma and 26/50 (52%) children with bruises. Rib (n = 56, 50%) and lower leg (n = 40, 36%) fractures were most detected. CONCLUSION: Occult fractures were detected in 32% of the children. Occult fractures were most prevalent if the initial clinical injury suggestive for NAT to request skeletal survey was a bruise, abusive head trauma or fracture.

PREVALENCE OF INJURIES AMONG THE POPULATION OF THE VINNITSA CITY.

Purpose - identify, summarize, systematize the causes and factors of injury; to study the state of injury among the population of a large city during 2016-2018 by nature, place and seasonality; analyze patients' case histories by severity of injuries; analyze the dynamics of the occurrence of injuries over time; to develop recommendations for measures to prevent domestic injuries among urban population. Conduct content analysis of scientific sources and methodological recommendations on occupational safety. To analyze 300 case histories of patients who look for some help at the Vinnytsia City Clinical Ambulance Hospital with injuries during 2016-2018. Systematize the information obtained by dividing it into categories such as the nature of the trauma, the time of occurrence, the place of traumatization and the dominant season. The analysis of the study showed that the domestic injury include: accidents in homes, backyards, in gardens, in the area and accounted for in 2018 - 72%; in 2017 - 67.4% and in 2016 - 70.4% of all cases. Injuries suffered by people on the street in 2018 - 25.3%; in 2017 - 25.5%; in 2016 - 22.4% of all cases. In 2016-2018, injuries in the population of Vinnitsa were as follows: in 2018 - 2.7%; in 2017 - 7.1% and in 2016 - 7.2%. By the nature of the injury, closed fractures are most often established. They won first place, second place took wounds. The third place was diagnosed with open fractures. They accounted for 15% in 2018; in 2017 - 9.1% and in 2016 - 4.7%, respectively. We have analyzed the dynamics of the occurrence of injuries over time. From the dynamics we find that the peak of injury occurs from 6.00 am to 12.00 pm. The dynamics of the occurrence of injuries by the seasons of the year were also evaluated. Most often, people are injured in spring.

Exposure to risperidone versus other antipsychotics and risk of osteoporosis-related fractures: a population-based study.

OBJECTIVE: Antipsychotics may increase serum prolactin, which has particularly been observed with risperidone. Further, hyperprolactinemia has been linked to osteoporosis-related fractures. Therefore, we investigated fracture risk in a nationwide cohort exposed to antipsychotics. METHODS: Swedish registers were used to identify adults with two consecutive dispensations of risperidone (n = 38 211), other atypical antipsychotics not including paliperidone (n = 60 691), or typical antipsychotics (n = 17 445) within three months between 2006 and 2013. An osteoporosis-related fracture was defined as a non-open hip/femur fracture in primary analyses. Cox regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Risperidone users were on average older (mean age of 68, 44, and 63 years for risperidone, other atypical antipsychotics, and typical antipsychotics respectively). Compared with other atypical antipsychotics, there was no association between risperidone and osteoporosis-related fractures in the overall (HR = 1.04, CI: 0.91-1.19) or age-stratified analyses. A significantly increased risk of typical antipsychotics (HR = 1.24, CI: 1.07-1.45) compared with other atypical antipsychotics remained for ages >45 years. CONCLUSION: Risperidone does not appear to be associated with an increased risk of osteoporosis-related fracture compared with other atypical antipsychotic agents as a group. For typical antipsychotics, a moderately elevated risk of hip fractures was noted compared with other atypical antipsychotics, possibly because of residual confounding.

Time-to-treatment is a risk factor for the development of pressure ulcers in elderly patients with fractures of the pelvis and acetabulum.

INTRODUCTION: Fractures of the pelvis and acetabulum are associated with pain and immobilization and, hence, pose the risk of developing a pressure ulcer - especially in elderly patients. In the literature, information on risk factors for the occurrence of pressure ulcers related to geriatric pelvic or acetabulum fractures is missing. METHODS: Consecutive in-hospital patients aged 55 years or older treated for closed pelvis and/or acetabulum fractures between 2013 and 2017 were retrospectively identified from an institutional prospective database. Epidemiologic characteristics and patient specifics with special focus on the time from admission to treatment, duration of hospitalization and comorbidities were retrospectively assessed by chart review. RESULTS: During the evaluated interval, 407 patients with isolated fractures of the pelvis or acetabulum (mean age 78 years, range 55 to 101 years, 69,3% female) were treated. A new pressure ulcer that developed during the hospitalization was observed in 46/407 patients (11.3%). This included pressure ulcers of stage 1 in 18/46 cases (39%), stage 2 in 24/46 cases (52%), and stage 3 in 4/46 cases (9%). No stage 4 ulcers were seen in this cohort. The mean duration of hospitalization was longer in patients with a pressure ulcer (25 days, SD 17) than in patients with no ulcers (12 days, SD 9; p < .001). Patients who developed a pressure ulcer, had waited significantly longer for treatment of their pelvis/acetabulum fracture when compared to patients without an ulcer (5 days, SD 5 vs. 3 days SD 4, p = =.001). A logistic regression analysis confirmed "time to treatment" as an independent risk factor for the occurrence of a pressure ulcer during hospitalization. In an analysis adjusted for the confounders age, male gender, diabetes and malignancy, the odds ratio to develop a pressure ulcer remained 1.10 (CI 1.03 to 1.19; c-value = 0.774, p = .008) for each day of waiting treatment. CONCLUSION: "Time to treatment" is an independent risk factor for the occurrence of a pressure ulcer during hospitalization after a pelvis/acetabulum fracture in elderly patients. Each day of waiting treatment increases the risk of developing a pressure ulcer by 10%.

The incidence of occult and missed surgical neck fractures in patients with isolated greater tuberosity fracture of the proximal humerus.

BACKGROUND: Occult and missed surgical neck fractures can be found in patients diagnosed with isolated greater tuberosity (GT) fracture during the follow up period. The purpose of this study was to retrospectively assess the incidence rate of occult and missed surgical neck fractures in those initially diagnosed with isolated GT fracture. METHODS: Records of patients diagnosed as having an isolated GT fracture were retrieved from a database in a medical center. Two senior orthopedic surgeons blindly reviewed all images of these patients three times to classify GT fracture types (split, avulsion and depression types), and recorded any surgical neck fractures found. Then a meeting was help to confirm the fracture types and presence of surgical neck fracture. RESULTS: Occult surgical neck fractures were found in 5 out of 68 (7.4%) patients, whereas missed surgical neck fractures were found in 3 out of 68 (4.4%) patients. In total, 32 patients had split type GT fracture, 32 had avulsion type and 4 had depression type. For those with occult surgical neck fractures, 7 had the split type GT fracture, while the remaining one had the avulsion type. Although the proportion of occult surgical neck fracture was higher in the split-type GT fracture (21.9%) than in the avulsion-type GT fracture (3.1%), the difference was not statistically significant (p = 0.056). CONCLUSION: Occult humeral surgical neck fractures occurred in 7.4% of isolated greater tuberosity fractures after re-evaluation, while missed humeral surgical neck fractures occurred in 4.4%.

Occult periprosthetic femoral fractures occur frequently during a long, trapezoidal, double-tapered cementless femoral stem fixation in primary THA.

The present study aimed to investigate the prevalence and clinical consequences of occult intra-operative periprosthetic femoral fractures in total hip arthroplasty (THA). Between 2012 and 2017, a total of 113 primary THAs were enrolled. The mean age of the patients was 66.4 ± 7.6 years. We assessed occult intra-operative periprosthetic femoral fractures with the use of computed tomography (CT) and risk factors, including age, sex, body mass index, diagnosis, stem size, and radiographic parameters of proximal femoral geometry were analyzed. We also assessed the differences in thigh pain and stem subsidence and alignment between the patients with and without occult periprosthetic femoral fracture. Occult intra-operative periprosthetic femoral fractures were found in 13 of 113 hips (11.5%). In 9/13 (69.2%) of occult fractures, fracture lines were started from the region below the tip of the lesser trochanter. Six periprosthetic femoral fractures (5.3%) were found during the operation. Out of the five hips that had detected femoral fractures around the lesser trochanter intra-operatively, four hips (80%) showed concurrent occult fractures on different levels. The female sex (P = .01) and canal filling ratio at 7 cm below the tip of the lesser trochanter (P = .01) were significantly different between the patients with and without occult periprosthetic femoral fracture. The sex was significantly associated with an increased risk in predicting an occult intra-operative periprosthetic femoral fracture (odds ratio of male, 0.25 compared with the female; 95% CI, 0.08-0.85; p = .02). There was a significant difference in the incidence of thigh pain between occult fracture group and non-occult fracture group (P < .05). There were no significant differences in stem subsidence and alignment between the patients with and without occult periprosthetic femoral fracture. All 13 cases of occult intra-operative periprosthetic femoral fractures were healed at the final follow-up. Occult periprosthetic femoral fractures are common during a long, trapezoidal, double-tapered cementless femoral stem fixation in primary THA, that CT scans are helpful to identify them, and that these fractures do not adversely affect the implant's survival if a rigid fixation of the implants has been achieved.

Analysing outcomes through orthopaedic trauma registry - A prospective cohort study.

OBJECTIVE: To develop a registry for recording injury-specific data to identify gaps and improve care. Methods: The prospective cohort study was conducted at Aga Khan University Hospital, Karachi, from June 2015 to July 2018 though enrollment of patients with limb trauma is continuing to date. Data on injuries and management related to Tibia shaft fractures was collected from medical records, and outcomes were assessed on follow-up visits. Internationally validated injury-specific scores were utilised for assessing functional, clinical and radiological outcomes. SPSS version 19 was used for data analysis. Results: There were 763 patients with 825 limb injuries. Of the injuries, 310(37.6%) related to upper limbs and 515(62.4%) to the lower limbs. Management was surgical for 741(89.9%) and conservative for 84(10.1%) injuries. Overall, 12(1.57%) patients died, and in 7(0.91%) cases mortality was unrelated to trauma and its management. There were 105 patients with tibia shaft fractures. Of them, 88(83.8%) were males and 17(16.2%) were females. At one-year follow-up excellent-to-good results were 12(92%) for intramedullary nailing followed by 7(78%) for open reduction and internal fixation. Conclusion: Registry data can be used to develop preventive strategies and to improve management protocols.

Laryngeal fracture presentation and management in United States emergency rooms.

OBJECTIVES/HYPOTHESIS: There are limited data on laryngeal fracture presentation and management in US emergency departments (EDs). We aimed to characterize patients who are diagnosed with laryngeal fractures in the ED and identify management patterns. STUDY DESIGN: Retrospective review of the Nationwide Emergency Department Sample (NEDS) from 2009 to 2011. METHODS: The NEDS was queried for patient visits with a primary diagnosis of open or closed laryngeal fracture (International Classification of Diseases, Ninth Revision codes 807.5 and 807.6). Patient demographics, comorbidities, ED management, and hospital characteristics were extracted. RESULTS: There were 3,102 ED visits with a diagnosis of laryngeal fracture during the study period. Mean patient age was 40.9 years (range, 3-93 years). The majority of patients were male (85.5%) and sustained a closed (vs. open) fracture (91.4%), with an overall mortality rate of 3.8%. The majority of patients were treated for more than one injury during the same visit (76.2%). Most patients were evaluated at a trauma hospital (53.9%), and most patients were admitted to the hospital (71.9%). Emergent intubation or tracheostomy was rarely reported (2.6% and 0.1% of all cases), and a minority of patients underwent fiberoptic flexible laryngoscopy in the ED (1.9%). Laryngeal fractures occurred more frequently during summer months (28.2%). Mean charge for the entirety of the ED stay was $4,957.34. CONCLUSIONS: Laryngeal fracture is rare and frequently associated with other injuries. The frequency of emergent airway procedure, imaging, and flexible fiberoptic laryngoscopy is lower than expected, raising concerns about appropriate workup and management or recognition of injury in the ED setting.

Epidemiology of open tibia fractures in a population-based database: update on current risk factors and clinical implications.

BACKGROUND: Open tibia fractures usually occur in high-energy mechanisms and are commonly associated with multiple traumas. The purposes of this study were to define the epidemiology of open tibia fractures in severely injured patients and to evaluate risk factors for major complications. METHODS: A cohort from a nationwide population-based prospective database was analyzed (TraumaRegister DGU®). Inclusion criteria were: (1) open or closed tibia fracture, (2) Injury Severity Score (ISS) ≥ 16 points, (3) age ≥ 16 years, and (4) survival until primary admission. According to the soft tissue status, patients were divided either in the closed (CTF) or into the open fracture (OTF) group. The OTF group was subdivided according to the Gustilo/Anderson classification. Demographic data, injury mechanisms, injury severity, surgical fracture management, hospital and ICU length of stay and systemic complications (e.g., multiple organ failure (MOF), sepsis, mortality) were collected and analyzed by SPSS (Version 23, IBM Inc., NY, USA). RESULTS: Out of 148.498 registered patients between 1/2002 and 12/2013; a total of 4.940 met the inclusion criteria (mean age 46.2 ± 19.4 years, ISS 30.4 ± 12.6 points). The CTF group included 2000 patients (40.5%), whereas 2940 patients (59.5%) sustained open tibia fractures (I°: 49.3%, II°: 27.5%, III°: 23.2%). High-energy trauma was the leading mechanism in case of open fractures. Despite comparable ISS and NISS values in patients with closed and open tibia fractures, open fractures were significantly associated with higher volume resuscitation (p < 0.001), more blood (p < 0.001), and mass transfusions (p = 0.006). While the rate of external fixation increased with the severity of soft tissue injury (37.6 to 76.5%), no major effect on mortality and other major complications was observed. CONCLUSION: Open tibia fractures are common in multiple trauma patients and are therefore associated with increased resuscitation requirements, more surgical procedures and increased in-hospital length of stay. However, increased systemic complications are not observed if a soft tissue adapted surgical protocol is applied.

Comparison of Open and Closed Hand Fractures and the Effect of Urgent Operative Intervention.

PURPOSE: To establish and compare the incidence of 30-day postoperative infection in surgically managed open and closed metacarpal and phalangeal fractures, and to determine whether open fractures treated urgently had a lower incidence of postoperative infection. METHODS: We conducted a retrospective analysis of patient demographics, comorbidities, and 30-day infection rates of patients undergoing operative fixation of metacarpal, proximal, or middle phalanx fractures from 2008 to 2015 using the American College of Surgeons' National Surgical Quality Improvement Program database. A total of 3,506 patients were identified and patient variables and infection incidence were compared between open and closed injuries, as well as open injuries managed within 1 day of admission and those treated on an elective basis or treated more than 1 day after admission. Bivariate analysis was used to determine independent risk factors for postoperative infection. RESULTS: Although 34.2% of open hand fractures were taken urgently to the operating room, the diagnosis of open fractures along with nonurgent surgical treatment for open fractures was associated with a low incidence of postoperative infection. In addition, smoking was a risk factor for postoperative infection although anatomic location (phalanx vs metacarpal) was not. CONCLUSIONS: Patients undergoing surgery for metacarpal or proximal/middle phalangeal fractures are not at greater risk for infection based on the diagnosis of open fracture alone. In addition, patients with open fractures who are taken to the operating room more than 1 day from presentation did not have a higher incidence of infection. Smoking is associated with increased 30-day infection rates after surgery, and surgeons should identify these patients for preoperative risk stratification, counseling, and postoperative wound monitoring. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Fractures of the femoral shaft in children: national epidemiology and treatment trends in England following activation of major trauma networks.

AIMS: The aim of this study was to describe the epidemiology of closed isolated fractures of the femoral shaft in children, and to compare the treatment and length of stay (LOS) between major trauma centres (MTCs) and trauma units (TUs) in England. PATIENTS AND METHODS: National data were obtained from the Trauma and Audit Research Network for all isolated, closed fractures of the femoral shaft in children from birth to 15 years of age, between 2012 and 2015. Age, gender, the season in which the fracture occurred, non-accidental injury, the mechanism of injury, hospital trauma status, LOS and type of treatment were recorded. RESULTS: A total of 1852 fractures were identified. The mean annual incidence was 5.82 per 100 000 children (95% confidence interval (CI) 5.20 to 6.44). The age of peak incidence was two years for both boys and girls; this decreased with increasing age. Children aged four to six years treated in MTCs were more likely to be managed with open reduction and internal fixation compared with those treated in TUs (odds ratio 3.20; 95% CI 1.12 to 9.14; p = 0.03). The median LOS was significantly less in MTCs than in TUs for children aged between 18 months and three years treated in both a spica (p = 0.005) and traction (p = 0.0004). CONCLUSION: This study highlights the current national trends in the management of closed isolated fractures of the femoral shaft in children following activation of major trauma networks in 2012. Future studies focusing on the reasons for the differences which have been identified may help to achieve more consistency in the management of these injuries across the trauma networks.

Clinical outcomes after open locked intramedullary nailing of closed femoral shaft fractures for adult patients in a Nigerian Hospital.

BACKGROUND: Femoral shaft fractures are common injuries in adults. Closed locked intramedullary nailing is the recommended treatment for femoral shaft fractures due to its high union rate. OBJECTIVE: The objective of this study is to determine the outcome of management of closed femoral shaft fractures in adult patients, using open locked intramedullary nailing. PATIENTS AND METHODS: This is a prospective study which was carried out on all adult patients aged 16 years and above who presented within 2 weeks of sustaining closed femoral shaft fractures to the accident and emergency unit of a University Teaching Hospital in Nigeria from January 2013 to December 2013. Pathological fractures were excluded from the study. The procedure was carried out using standard techniques, and each patient was followed up for a minimum of 1 year. RESULTS: Forty-three patients were recruited into the study. They had a mean age of 36.9 ± 11.7 years, with a male to female ratio of 2.9:1. The most common cause of closed femoral shaft fractures was road traffic crashes (95.3%), with motorcycle-related injuries found to be the highest type (56.1%). The rate of union in the study was 95.3%. The average time to radiological union was 14.0 ± 1.2 weeks while the mean time to painless full weight bearing was 14.2 ± 1.2 weeks. Among the complications encountered were broken nails (4.7%), infection, loosening of the distal screw, and limb length discrepancy (2.3% each). Using Thoresen's criteria, excellent results were obtained in 93% and poor results in 4.7% of patients. CONCLUSION: Open locked intramedullary nailing gives excellent clinical outcomes with high union and low complication rates in the management of closed femoral shaft fractures in adult patients.

The challenging surgical treatment of closed distal humerus fractures in elderly and octogenarian patients: radiographic and functional outcomes with a minimum follow-up of 24 months.

INTRODUCTION: The main purpose of this retrospective, non-randomized, case series study was to evaluate the clinical and radiographic outcomes of distal humerus fractures (DHFs) in a consecutive series of elderly patients operatively treated by two surgeons, and second, to identify proper indications for two elderly age ranges and two fracture pattern groups. MATERIALS AND METHODS: From January 2009 to June 2014, 51 patients (pts) underwent open reduction and internal fixation (ORIF) using the locking compression plate (LCP) distal humerus plate (DHP) system at our institution. Medical records and radiographs were retrospectively assessed. Patients were divided into 3 groups according to gender, age (pts <85 years, pts ≥85 years) and AO classification (13-B1-B2-C1-C2 or 13-C3). All subjects completed MEPS, Quick-DASH and SF-36 PCS/MCS scores at final follow-up, and statistical analysis was performed. RESULTS: 36 patients (20 women, 16 men), mean age 80.3 years, with AO type 13-B and 13-C DHFs were included with a mean follow-up of 56 months (range 24-92). The most common mechanism of trauma was a fall from ground level (55.6%). The mean MEPS was 78.9 points, Quick-DASH 28.4, SF-36 PCS 48.3 and MCS 48.9. There was statistically significant evidence that having a 13-C3 fracture leads to worse results in MEPS, Quick-DASH and SF-36. The female gender correlates with worse results in SF-36. The patients ≥85 years had a worse prognosis according to Quick-DASH and SF-36, while the AO 13-C3 pattern obtained the worst ROM outcomes versus AO 13 B1-B2-C1-C2 (normal ROM 0°-140°): mean ROM 24°-114° vs 10°-130°, mean flexion deficit 26° vs 10°, mean extension deficit 24° vs 10°, respectively). Complications were presents in 36.1% of patients, overall belonging to the AO type 13-C fracture pattern and to the group ≥85 years. CONCLUSION: These study data seem to confirm our hypothesis that plate fixation for DHFs guarantees adequate fracture osteosynthesis and satisfactory functional outcomes at medium to long-term follow-up, not only in elderly patients, but also in octogenarian osteoporotic patients (≥85 years) with 13-C1 and 13-C2 fracture patterns, while an alternative solution should be considered for type C3 fractures, even in a primary trauma setting.

Magnetic resonance imaging for verifying hip fracture diagnosis why, when and how?

INTRODUCTION: Hip fractures are commonly diagnosed by plain radiography. When a patient presents with negative radiographs and high clinical suspicion of fracture, guidelines recommend proceeding with magnetic resonance imaging (MRI) to diagnose the patient. The aim of this study was to assess the use of MRI in diagnosing hip fractures following trauma to the hip and describe clinical outcome after MRI-diagnosed hip fractures. The perspective was to develop new recommendations for MRI use. MATERIALS AND METHODS: 616 patients at a university hospital fulfilled the inclusion criteria of having an MRI scan of the hip following trauma between the years of 2005 and 2014. Data was collected from the patients' medical records. RESULTS: The annual number of MRIs increased over the ten-year period. Out of 616 MRI scans 228 (37%) showed fracture of the hip with a dominance of trochanteric fractures, 185 (30%) revealed pelvic fracture and 183 (29%) were negative. No patient with acute pelvic fracture had associated fracture of the hip. The main reason to proceed with MRI was a strong clinical suspicion of fracture in patients with negative initial radiographs. Amongst the 228 patients with fracture, 187 (82%) were treated operatively. Of patients with hip fracture, 90 (39%) patients suffered a general complication and 11 (5%) had hip complications. The complication rate of patients with fracture on MRI was compared to that of a cohort of general hip fracture patients at our hospital. No significant difference in twelve months' survival or general complications could be found, but the MRI group had a significantly lower hip complication rate. CONCLUSION: The diagnosis set by MRI, with high share of pelvic fractures or no fracture, reflects the difficulty in differential diagnosing this group of patients. The rate of occult hip fractures was low and patients with pelvic fractures already known from X-ray did not have additional hip fractures. We found an increase in the annual number of MRIs during the 10-year-period. MRI-diagnosed hip fracture patients do not suffer more complications than the regular hip fracture patient.

Reaming Does Not Affect Functional Outcomes After Open and Closed Tibial Shaft Fractures: The Results of a Randomized Controlled Trial.

OBJECTIVES: We sought to determine the effect of reaming on 1-year 36-item short-form general health survey (SF-36) and short musculoskeletal function assessment (SMFA) scores from the Study to Prospectively Evaluate Reamed Intramedullary Nails in patients with Tibial Fractures. DESIGN: Prospective randomized controlled trial.1319 patients were randomized to reamed or unreamed nails. Fractures were categorized as open or closed. SETTING: Twenty-nine academic and community health centers across the US, Canada, and the Netherlands. PATIENTS/PARTICIPANTS: One thousand three hundred and nineteen skeletally mature patients with closed and open diaphyseal tibia fractures. INTERVENTION: Reamed versus unreamed tibial nails. MAIN OUTCOME MEASUREMENTS: SF-36 and the SMFA. Outcomes were obtained during the initial hospitalization to reflect preinjury status, and again at the 2-week, 3-month, 6-month, and 1-year follow-up. Repeated measures analyses were performed with P < 0.05 considered significant. RESULTS: There were no differences between the reamed and unreamed groups at 12 months for either the SF-36 physical component score [42.9 vs. 43.4, P = 0.54, 95% Confidence Interval for the difference (CI) -2.1 to 1.1] or the SMFA dysfunction index (18.0 vs. 17.6, P = 0.79. 95% CI, -2.2 to 2.9). At one year, functional outcomes were significantly below baseline for the SF-36 physical componentf score, SMFA dysfunction index, and SMFA bothersome index (P < 0.001). Time and fracture type were significantly associated with functional outcome. CONCLUSIONS: Reaming does not affect functional outcomes after intramedullary nailing for tibial shaft fractures. Patients with open fractures have worse functional outcomes than those with a closed injury. Patients do not reach their baseline function by 1 year after surgery. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

In-Hospital Mortality Following Open and Closed Long Bone Fracture: A Comparative Study.

BACKGROUND: Open fracture is a serious orthopaedic injury that can lead to significant patient morbidity and mortality. There is limited data on the mortality risk for open compared to closed long bone fracture. METHODS: The Nationwide Inpatient Sample was used to identify all patients who were admitted with a long bone fracture in the United States between 1998 and 2010. Cox proportional hazards regression modeling was used to calculate the hazard ratio (HR) and 95% confidence interval (CI) of mortality. RESULTS: After adjusting for age, gender, race, insurance, and comorbidities, the HR of mortality was 2.89 (95% CI, 2.56-3.28; p<0.001) for open compared to closed fracture. Stratified by anatomical site, the HR of mortality for open compared to fracture was 3.43 for femur (95% CI, 2.78-4.23; p<0.001), 2.81 for tibia or fibula (95% CI, 2.17-3.64; p<0.001), 2.54 for humerus (95% CI, 1.81-3.56; p<0.001), and 1.56 for radius or ulna (95% CI, 1.10-2.23; p=0.014). CONCLUSIONS: This data suggests that open fracture carries a worse prognosis compared to closed fracture at the same anatomical site.
