RESUMO

Despite the progress in tibial fracture care, some patients contract infection following intramedullary nailing. We analyzed which risk factors could predict infection in 171 tibial fractures. The independent variables included age, gender, body mass index, and comorbidities, along with external factors of fracture pattern, nailing settings, and treatment processing time. A multiple logistic regression was used to identify infection risk factors. The risk of infection significantly increased according to the open grading, the fractures' classification, time until antibiotic administration, and time until nailing. Gustilo type I fractures presented a higher rate of infection than expected, explained by a longer delay before surgery. The probabilistic equation allows infection prediction with high sensitivity and specificity. In total, we showed that no antibiotics' prescription in emergency service and a transverse fracture pattern were predictors of infection. An infection risk score can be computed, aiding surgeons in decision making. Outcomes could improve keeping these observations in mind. Level of evidence: Retrospective cohort study. Level iii.

RESUMO

Surgical treatment of lateral ankle instability can be performed with or without allograft. We compared these two technical options referring to patients' functional, radiological and ultrasound data. Forty patients were surgically treated for lateral pain- ful instability of the ankle. Twenty patients underwent ligamentoplasty using the Broström-Gould technique and twenty underwent a ligamentoplasty by allograft tendon. Patients were matched in age and gender. The assessment was done at 2.5 years postoperatively by functional scores (Olerud & Molander, and Foot & Ankle Outcome), dynamic x-rays (focused on varus and anterior drawer stress tests) and ultrasound examination (focused on anterior talo-fibular and calcaneo-fibular ligaments). No significant difference was found between the two techniques for all scores. Functional scores were more than 75% and the complication rate was low (<10%). Regarding the surgical technique, the tendon allograft could not prove to be more beneficial.

RESUMO

AIMS: Low haemoglobin (Hb) at admission has been identified as a risk factor for mortality for elderly patients with hip fractures in some studies. However, this remains controversial. This study aims to analyze the association between Hb level at admission and mortality in elderly patients with hip fracture undergoing surgery. PATIENTS AND METHODS: All consecutive patients (prospective database) admitted with hip fracture operated in a tertiary hospital between 2012 and 2016 were analyzed. We collected patient characteristics, time to surgery, duration and type of surgery, comorbidities, Hb at admission, nadir of Hb after surgery, the use and amount of red blood cells (RBCs) transfusion products, postoperative complications, and death. The main outcome measures were mortality at 30 days, 90 days, 180 days, and one year after surgery. RESULTS: We included 829 patients; the mean age was 81 years (sd 11). Mortality at 30 days, 90 days, 180 days, and one year was 5.7%, 12.3%, 18.1%, and 23.5%, respectively. The highest mortality was observed in patients aged over 80 years (162/557, 29%) and in male patients (85/267, 32%). Survival at 90 days, 180 days, and one year after surgery was significantly lower in patients with a Hb level below 120 g/l at admission. In multivariate analysis, Hb level below 120 g/l at admission was found to be an independent factor associated with mortality (adjusted hazard ratio (aHR) 1.68 (95% confidence interval (CI) 1.22 to 2.31); p = 0.001), along with age (aHR 1.06 (95% CI 1.04 to 1.06); p < 0.001), male sex (aHR 2.19 (95% CI 1.61 to 2.96); p < 0.001), and need for RBC transfusions (aHR 1.10 (95% CI 1.02 to 1.19); p = 0.01). CONCLUSION: Our results suggest that low Hb at admission along with age and RBC transfusions is significantly associated with short- and long-term mortality after hip fracture surgery, independently of comorbidity confounders. Further studies should be performed to understand how preoperative Hb could be taken into account in perioperative management. Cite this article: Bone Joint J 2019;101-B:1122-1128.

RESUMO

BACKGROUND: In 2015, an earthquake killing 9,000 and injuring 22,000 people hit Nepal. The Tribhuvan University Teaching Hospital (TUTH), a reference tertiary hospital, was operational immediately after the earthquake. We studied the profile of earthquake victims admitted in TUTH and assessed what factors could influence hospital length of stay. METHODS: An earthquake victim dataset was created based on patient records, with information on sex, age, date of admission and discharge, diagnosis, and surgical intervention. We performed an initial descriptive overview of the earthquake victims followed by a time-to-event analysis to compare length of hospital stay in different groups, using log rank test and cox regression to calculate Hazard Ratios. RESULTS: There were in total 501 admitted victims, with the peak of admissions occurring on the fifth day after the earthquake. About 89% had injury as main diagnosis, mostly in lower limbs, and 66% of all injuries were fractures. Nearly 69% of all patients underwent surgery. The median length of hospital stay was 10 days. Lower limb and trunk injuries had longer hospital stays than injuries in the head and neck (HR = 0.68, p = 0.009, and HR = 0.62 p = 0.005, respectively). Plastic surgeries had longer hospital stays than orthopaedic surgeries (HR = 0.57 p = 0.006). Having a crush injury and undergoing an amputation also increased time to discharge (HR = 0.57, p = 0.013, and HR = 0.65 p = 0.045 respectively). CONCLUSIONS: Hospital stay was particularly long in this sample in comparison to other studies on earthquake victims, indirectly indicating the high burden TUTH had to bear to treat these patients. To strengthen resilience, tertiary hospitals should have preparedness plans to cope with a large influx of injured patients after a large-scale disaster, in particular for the initial days when there is limited external aid.

RESUMO

INTRODUCTION: Intramedullary (IM) nailing is the gold standard treatment for tibial shaft fractures, but can be associated with various mechanical complications, including delayed union. HYPOTHESIS: We believe that complications do not occur randomly, but in certain conditions that contribute to their development. Risk factors likely to predict delayed union can be identified to support prevention. MATERIALS AND METHODS: A cohort of 171 fractures treated by IM nailing between 2005 and 2015 was reviewed retrospectively. Independent variables included intrinsic, patient-related factors and extrinsic factors such as those related to the fracture or surgery. A multiple logistic regression model was used to determine which factors can predict each type of complication. RESULTS: Delayed union occurred in 22.8% of patients. Smoking and high-energy trauma were risk factors. Hardware breakage was significantly reduced (p<0.05) when the nail diameter was greater than 10mm. A nail diameter/reamer diameter ratio outside the recommended limits (0.80-0.99) was more likely to be associated with screw failure. Diabetes is a risk factor for hardware migration, which itself is associated with other complications. DISCUSSION: Nonunion is the most common complication after IM nailing of tibial shaft fractures. Smoking cessation after a fracture is necessary in our opinion, even if the literature is ambivalent on this aspect and stopping to smoke once the fracture occurs may not be sufficient to prevent a poor outcome. Use of a nail diameter/reamer diameter between 0.80 and 0.99 favors union and prevents hardware breakage. Hardware migration in a diabetic patient may be a warning sign of other types of complications. LEVEL OF EVIDENCE: Retrospective cohort study. Level IV.

RESUMO

Irreducible fracture dislocation of the ankle is a rare condition. Multiple cases have been described throughout the literature. Different known etiologies involve the distal fibula, deltoïd ligament and tendons of the posteromedial malleolar region. More specifically, trapping of the Posterior tibialis tendon has been described at several levels from the inside of the ankle joint, through the syndesmosis and in some cases in the fibula tibial interosseous space depending on the energy of trauma. We hereafter propose a case report and a review of previous cases of posterior tibialis tendon dislocation proximally in the interosseous space of the lower leg. The aim of this review is to point out common features and clues for early management in order to avoid overlooking these rare lesions as they may lead to major functional impairment of the ankle joint.

RESUMO

We report the case of a 55-year-old male patient who presented to the emergency department after sustaining a right ankle trauma. Swelling and tenderness of the lateral aspect of the right ankle were present on physical examination without evidence of motor or sensory deficit. Ankle radiographs were performed and showed two bony fragments, the first located postero-inferiorly to the cuboid bone while the second was adjacent to the tip of the lateral malleolus. The diagnosis of an os peroneum fracture was made with high suspicion of an associated peroneus longus tendon rupture. Computed tomography (CT) and magnetic resonance imaging (MRI) of the right ankle confirmed the diagnosis of a subtotal retracted tendinous rupture. Successful surgical repair of the injured tendon was performed. This article illustrates the imaging findings of an os peroneum fracture with its associated tendinous injury and reviews the literature.

RESUMO

OBJECTIVES: To assess the value of a radiographic score for the detection of delayed union in nailed fractures. METHODS: The modified radiographic union score (mRUS) values were determined by three separate radiologists on 259 radiographic sets of 58 nailed tibial or femoral fractures obtained at different timepoints after fracture (mean of 4.5 radiographic sets per fracture). A surgeon determined fracture outcome (normal or delayed union) at a mean of 192days after injury. Mean radiographic scores obtained at different timepoints after fracture were compared between fractures with normal or abnormal healing at follow-up. RESULTS: The mean score values increased significantly over time for fractures with normal healing for all readers (p<0.001). The mean score values determined 11-14 weeks after injury were higher in fractures with normal healing than in fractures with delayed union at follow-up (p<0.05). Scoring of radiographs obtained at about 3 months after injury or later enabled detection of fractures with delayed union with a sensitivity of 0.63-0.77 and a specificity of 1.0 (area under curve: 0.77- 0.88). CONCLUSIONS: The mRUS score can contribute to the detection of delayed union at a delay of about 3 months after injury in nailed shaft fractures.
