RESUMO
Background and Objectives: The adequate therapy of thoracolumbar fractures in the elderly population is still controversially discussed. The aim of this study was to evaluate and compare the results of conservatively and surgically treated younger (≤60a) and elderly patients (>60a) with fractures of L1. Materials and Methods: Patients (231) with isolated L1 fractures were included and treated at the University Clinic of Orthopedics and Trauma Surgery, Division of Trauma Surgery, Medical University of Vienna, during the observation period of 2012-2018. Results: Conservative treatment led to a significant increase in the vertebral and bi-segmental kyphosis angle in both age groups (young vertebral: p = 0.007; young bi-segmental: p = 0.044; old vertebral: p = 0.0001; old bis-segmental: p = 0.0001). A significant reduction in the vertebral angle in both age groups was achieved after operative treatment (young: p = 0.003, old: p = 0.007). The bi-segmental angle did not significantly improve after surgery in both age groups (≤60a: p = 0.07; >60a: p = 1.0). Conclusions: The study shows that conservative treatment does not seem to be sufficient for a correction of radiological parameters in young and elderly patients. In contrast, operative treatment led to a significant improvement of the vertebral kyphosis angle, without changing the bi-segmental kyphosis angle. These results suggest a greater benefit from operative treatment in patients ≤ 60a than in older patients.

BACKGROUND: There is still no evidence in literature for damage control orthopaedics (DCO), early total care (ETC) or using external fixation solely in fractures of the long bones in multi-system-trauma. The aim of this study was to determine parameters influencing the choice of treatment in clinical routine (DCO, ETC, or EF) in femoral or tibial shaft fractures in combination with multi-system-trauma, severe soft tissue damage or both. METHODS: Data of 236 patients with 280 fractures of long bones of the lower extremities treated at a level I trauma center were analysed. Clinical parameters on arrival (age, sex [m/f], ISS, fracture site [femur/tibia], soft tissue damage [closed or open fractures according to the Gustilo-Anderson classification], pulmonary injury [yes/no]) were collected and analysed whether they influence the choice of upcoming treatment (DCO/ETC/EF). RESULTS: Our findings showed that high ISS and severe soft tissue damage (grade III) significantly correlated with DCO. High ISS, old age, female sex and fracture site (tibia) correlated with EF. This group of sole use of external fixation had highest rate of complications, 69% were associated with at least one complication. CONCLUSION: Severely injured patients are treated significantly more often with DCO or EF. The presence of higher ISS (≥16) and of type III open fractures increased the use of DCO. However, ISS, fracture-site, patient's age, type III open fractures or sex (female) increased the use of EF compared to ETC.

BACKGROUND: One of the currently used surgical techniques in isolated type II SLAP lesions is arthroscopic SLAP repair. Postoperatively, patients tend to suffer from a prolonged period of pain and are restricted in their sports activities for at least 6 months. The aim of this study was to prospectively evaluate the clinical outcome as well as the postoperative course of pain after arthroscopic type II SLAP repair. METHODS: Outcome measures were assessed using the Individual Relative Constant Score (CSindiv), the American Shoulder and Elbow Surgeons (ASES) Score, the Visual Analogue Scale (VAS), and the Short Form 36 (SF-36). Data were collected preoperatively, as well as at 3, 6, 12 and >24 months postoperatively. RESULTS: Eleven patients with an average age of 31.8 years (range: 22.8-49.8 years) underwent arthroscopic repair of isolated type II SLAP lesions. Mean follow-up time was 41.9 months (range: 36.1-48.4 months). 6 months after surgery, there was a statistically significant improvement of function according to the CSindiv (p = 0.004), the ASES Score (p = 0.006), and the SF-36 subscale "physical functioning" (p = 0.014) and a statistically significant decrease of pain according to the VAS (p = 0.007) and the SF-36 subscale "bodily pain" (p = 0.022) compared to preoperative levels. CONCLUSIONS: Arthroscopic repair of isolated type II SLAP lesions with suture anchors leads to a satisfactory functional outcome and return to pre-injury sports levels, with delayed, but significant pain relief observed 6 months after surgery. Thus, a return to sports should not be allowed earlier than 6 months after surgery, when patients have reached pain-free function and recovered strength.

BACKGROUND: Unstable Neer Type IIB fractures require meticulous surgical treatment. Thus, the aim of this study was to present long-term outcomes after plate fixation and minimally invasive coracoclavicular (CC) stabilization using screw fixation. METHODS: A consecutive series of patients with unstable Neer Type IIB displaced clavicle fractures, treated by open reduction and internal fixation (ORIF) with a plate and additional screw fixation for coracoclavicular ligament instability, was reviewed in order to determine long-term clinical and radiological outcome. RESULTS: Seven patients, six males and one female, with a mean age of 37 ± 8 years (median: 36 years; range, 28-51 years), were evaluated. At latest follow-up, after a mean of 67 months (range, 11-117 months), patients presented with the following mean scores: DASH: 0.57, ASES: 98.81, UCLA: 34.29, VAS: 0.43, Simple Shoulder Test: 11.57. However, two complications were observed: one case of implant loosening and one non-union. There were no differences observed between the CC distances comparing postoperative X-rays to those in final follow-up. In 25% of our patients early postoperative complications occurred. In all patients reoperation was necessary to remove the implanted screw. CONCLUSION: The results of the present study indicate that the treatment of Neer Type IIB lateral clavicle fractures with ORIF using a plate and additional CC screw fixation, leads to satisfying clinical and radiological outcomes in the long-term. However, considering an early postoperative complication rate of 25% and a 100% rate of secondary surgery due to removal of the CC screw does not seem to justify this technique anymore.

BACKGROUND: The acromioclavicular (AC) joint dislocation is a major reason for shoulder instability. Different concepts of treatment and surgical methods are described in the literature. Thus, the purpose of this study was to present our data of long-term follow-up of patients having undergone treatment of acromioclavicular (AC) joint dislocation using the Bosworth Screw with additional K-wiring. METHODS: This study was conducted as a retrospective single centre data analysis. All patients treated operatively for AC joint dislocation with a Bosworth screw and additional K-wire fixation at our Department were asked to participate in this study. RESULTS: The study population consisted of 22 patients, 20 male and 2 female, with a mean age of 40 years ±15.6 years. Three grade-II lesions, 13 grade-III lesions, four grade-IV lesions and two grade-V lesions according to the Rockwood classification were found. The overall mean clinical outcome at the latest follow up was: Constant 95, DASH 6.4, ASES 94.6, SST 99.02, UCLA 33.1, ACJI 91.82 and VAS 0.29 - representing a good-to-excellent long-term outcome in all patients after at least 2 years follow-up (range; 2 - 19 years). Overall, 19 patients (86%) reported to be very satisfied with the achieved result, 15 patients (68%) reported to be able to participate in every sports activity and 16 patients (73%) reported to be able to perform their daily work without limitations. Overall, complications occurred in three patients (14%). Only one patient remained unsatisfied with the achieved result. CONCLUSION: Summarizing, our reported results showed that surgical fixation of acute AC joint dislocation with a Bosworth screw and additional K-wire fixation leads to good-to-excellent functional outcome and highly satisfactory results in the majority of patients. Despite its complications, in accordance with our results, Bosworth screw fixation with additional K-wiring in AC joint dislocation represents an adequate surgical procedure. LEVEL OF EVIDENCE: Level IV, retrospective study.

BACKGROUND: Computer navigation-assisted surgery for musculoskeletal tumors has shown to reduce the risk of intra-lesional margins in resection. Experiences with this method are still limited to smaller case series. METHOD: We reviewed our first experiences in 24 patients in whom computer navigation-assisted surgery had been performed. In 7 of these patients (6 male and 1 female), this has influenced the surgical treatment plan and navigation was used for both tumor resection and reconstruction. Three of the patients suffered from a chondrosarcoma, 2 from an osteosarcoma, 1 from a fibrosarcoma and 1 from an Ewing's sarcoma. Tumors were localized in the femur (n = 2), the tibia (n = 1), the sacrum (n = 1), the humerus (n = 1), the ilium (n = 1) and in the gluteal region (n = 1). RESULTS: The mean registration error was 0.9 mm. No intra-operative complications occurred. Two postoperative complications were observed which required revision surgery. Except for one marginal resection, all tumors were excised with wide margins. One patient suffered from a local recurrence, and one patient died of disease after distant metastatic dissemination. CONCLUSION: Computer navigation-assisted surgery represents a safe and helpful tool for the resection of musculoskeletal tumors and may influence surgical treatment plans in selected cases to provide more limited resections. Surgeons should be aware of risks considering biomechanical and oncological consequences in doing so. Further investigations and the evaluation of newer techniques (e.g., computed tomography-guided navigation) are needed to assess long-term outcomes of computer navigation assistance in musculoskeletal tumor surgery.

BACKGROUND: In long-term survivors of osteosarcoma and Ewing sarcoma treated with the addition of radio- and chemotherapy, low bone mineral density (BMD) and fractures have been observed, presumably resulting from these adjuvants. Because patients with chondrosarcoma usually are not treated with conventional adjuvant treatment, observation of low BMD in patients with chondrosarcoma presumably would be the result of other mechanisms. However, BMD in patients with a history of chondrosarcoma has not been well characterized. QUESTIONS/PURPOSES: The aim of our study was to address the following questions: (1) Do long-term survivors of chondrosarcoma have normal BMD and, if not, which factors contribute to low BMD? (2) Is there a greater risk of fracture and does the Fracture Risk Assessment Tool (FRAX(®)) score reflect fracture likelihood? METHODS: All known patients with a history of chondrosarcoma treated at our institution before 2006 were identified. Of 127 patients believed to be alive at the time of this study, 30 agreed to participate in this study (11 females, 19 males; mean age at surgery, 39 ± 12 years; mean followup, 12 ± 5 years). With the data available, the 30 participants were not different from the 97 nonparticipants in terms of age, sex, BMI, tumor grade, tumor location (axial versus appendicular, lower extremity versus elsewhere), and use of any treatment known to influence osteopenia (chemotherapy, lower extremity surgery). BMD was measured and history of fractures was assessed using a questionnaire. The patients´ BMD measurements in this study were sex- and age-matched with a normative sex- and age-categorized reference population reported by Kudlacek et al. Associations were tested by univariate regressions and ANOVAs of all measures of BMD and eligible oncologic and demographic factors. RESULTS: Eighteen of 30 (60%) patients had a pathologic BMD according to the WHO dual-energy x-ray absorptiometry definition, 15 (50%) had osteopenia, and three (10%) had osteoporosis. T-scores in the study cohort were lower than reference values for the femur neck (mean difference, 0.64; 95% CI, 0.27-1.01; p < 0.0015), but not for the spine (mean difference, 0.39; 95% CI, -0.06 to 0.84; p = 0.09). Thirteen patients (45%) reported a history of fractures not distinguishing between low and high impact. The incidence of fractures was 2.8 greater than expected from a comparison with a published microcensus survey of the Austrian population. No effect of the FRAX(®) score on fracture risk could be identified (p = 0.057). CONCLUSIONS: Long-term survivors of chondrosarcoma appear to be at greater risk for having low BMD develop than the healthy population. Although these results are preliminary and based on a very small sampling of patients, if they can be confirmed in larger studies, BMD assessment by dual-energy x-ray absorptiometry might be considered as these patients are followed posttreatment by sarcoma care units. The reasons for low BMD still must be elucidated. LEVEL OF EVIDENCE: Level IV, prognostic study.

PURPOSE: To evaluate the clinical and functional outcomes for anatomic anterior cruciate ligament (ACL) reconstruction using the all-inside technique with a minimum follow-up of 24 months. METHODS: Patients undergoing anatomic ACL reconstruction via the all-inside technique between January 2011 and October 2012 were reviewed for inclusion in this study. Functional outcome measures, including the Lysholm score, International Knee Documentation Committee score, visual analog scale score, and Tegner Activity Scale, were used to evaluate outcomes before surgery and at 3, 6, 12, and > 24 months. At final follow-up, anteroposterior knee stability was assessed with KT-2000 (MEDmetric, San Diego, CA) measurements. RESULTS: Of the 92 patients who underwent primary all-inside ACL reconstruction, 79 patients returned to final follow-up with a minimum of 2 years. There were 53 men and 26 women with a mean age of 29 years (range, 18 to 54 years) and a mean follow-up of 29 months (range, 24 to 45 months). The International Knee Documentation Committee score (44.6 v 89.7, P < .0001), Lysholm score (53.4 v 93.1, P < .001), visual analog scale score (5 v 0.1, P < .001), and Tegner activity score (2 v 6, P < .001) showed a significant improvement between baseline and final clinical follow-up. The mean side-to-side KT-2000 difference at final follow-up was 1.7 mm (range; 0 to 6 mm). Overall 10 patients (12.7%) sustained an ACL graft rerupture after a mean of 17.6 months (range, 6.9 to 28.6 months). CONCLUSIONS: The current data support our first hypothesis that primary anatomic ACL reconstruction using the all-inside technique leads to improved functional outcomes between baseline and clinical follow-up at 24 months. Further, there was no difference in knee stability between the ACL reconstructed- and the contralateral normal knee at 24 months, which confirms our second hypothesis.

PURPOSE: Traumatic injuries to the cervical spine are frequently accompanied by cervical spinal cord injuries-often necessitating tracheostomy. The purpose of this study was to evaluate patient characteristics and outcomes after undergoing anterior cervical spine fusion (ACSF) with tracheostomy. METHODS: All patients with cervical spine injury (CSI) who underwent ACSF and tracheostomy between December 1992 and June 2014 were included in this retrospective data analysis. The study group consisted of 32 men (84 %) and six women (16 %), with an average age of 47 ± 20 years. Blunt trauma to the cervical spine was the cause of CSI in all 38 patients. RESULTS: The mean Injury Severity Score (ISS) was 30.50 ± 6.25. Eighteen patients sustained severe concomitant injuries related to the spinal injury. In 15 patients (39.5 %), traumatic brain injury (TBI) with fractures of the cranium and/or intracranial lesions were observed. The mean Glasgow Coma Scale (GCS) score was 11 ± 4.5 (range 3-15). Two tracheostomies (5.3 %) were performed simultaneously with ACSF. The remaining 36 were performed with an average "delay" of 15 ± ten days. We observed no difference in time to tracheostomy among patients initially presenting with an American Spinal Injury Association (ASIA) score of either A, B, C or D. Only two patients (5.3 %) were identified as having an infection at the site of ACSF after placement of a tracheostomy. There were no deaths directly related to airway difficulties in our cohort. CONCLUSIONS: Our data show that tracheostomy is safely performed after an average of 15 days post-ACSF, thereby being associated with a very low rate of complications. However, future prospective randomised studies are needed to identify the optimal timing of tracheostomy placement after ACSF. LEVEL OF EVIDENCE: IV; retrospective case series.

BACKGROUND: As the awareness towards gender-specific therapies continues to increase among all fields of medicine, so does the need for gender-sensitive evaluations of established surgical techniques. With a higher likelihood of anterior cruciate ligament injury in women, a critical assessment of the functional outcome of anterior cruciate ligament reconstruction regarding patient sex is indispensable. Almost all pre-existing literature on this subject is based on anterior cruciate ligament reconstructions carried out before 2008, when 'all-inside' techniques did not exist. This implicates the need to investigate this technique towards its differences in outcome between male and female patients. OBJECTIVES: The purpose of this study was to determine whether there is a difference concerning the functional outcome of an 'all-inside' technique for anterior cruciate ligament reconstruction in female patients when compared to a cohort of male patients matched for body mass index and age. DESIGN: Retrospective analysis. METHODS: All female patients who underwent anterior cruciate ligament reconstruction using an all-inside technique between 2011 and 2012 were examined for inclusion. Functional outcome parameters investigated included the Lysholm Knee Score, International Knee Documentation Committee score, Visual Analogue Scale score and the Tegner Activity Scale. All parameters were documented before surgery and at 3-, 6-, 12- and >24 months follow-up. At 24-month follow-up, anterior-posterior knee laxity was tested using the KT-2000 arthrometer device. For comparison, an equivalent group of male patients who underwent the same procedure was matched. RESULTS: 27 female patients were matched with 27 male patients. The average age was 29 years, and a mean follow-up of 90 months could be achieved with 27 of patients reaching a follow-up of > 10 years. The evaluated scores showed no significant difference between female and male patients. Women presented with poorer functional outcome at 3- as well as 6-month follow-ups compared to men, without reaching statistical significance. After 12 months, no further differences could be found. CONCLUSION: This study proved that an all-inside technique for anterior cruciate ligament reconstruction is able to produce the same functional outcome in female as in male patients at long-term follow-up. The results on short-term outcome indicate the need for further research towards gender-specific differences after anterior cruciate ligament reconstruction, their potential causes and potential of improvement. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

The aim of this retrospective study was to present an epidemiological overview of paediatric nonelectric-scooter-related injuries, focusing on changes in injury mechanism and frequency. A retrospective, descriptive data analysis at a Level I trauma centre, including patients aged from 0 to 18 years injured by riding nonelectric scooters, was performed. The observation period ranged from January 2015 to December 2022. The total study population consisted of 983 (mean age: 7.9 ± 4.0 years) children and adolescents, with most patients being male (800/983; 81.4%). The frequency of nonelectric scooter injuries was relatively consistent over the observation period. Patients sustained mostly minor injuries (lacerations, bone contusions, sprains) (527/983; 53.6%), followed by head injuries (238/983; 24.5%), limb fractures (166/983; 16.9%) and trunk injuries (52/983; 5.3%). However, a few patients sustained severe injuries, including skull fractures (7/238; 2.9%), intracranial haematoma (4/238; 1.7%) or lacerations of abdominal organs (4/52; 7.7%). This study presented a consistently high frequency of scooter injuries in children. Children under 15 years were the most affected by scooter-related injuries. Although most injuries were minor, serious injuries occurred that should not be underestimated. Hence, we emphasise the use of protection gear and recommend raising awareness among parents and children.
RESUMO
BACKGROUND: Hip fractures are becoming a growing concern due to an aging population. The high costs to the healthcare system and far-reaching consequences for those affected, including a loss of independence and increased mortality rates, make this issue important. Poor nutritional status is a common problem among geriatric patients and is associated with a worse prognosis. Nutritional screening tools can help identify high-risk patients and enable individualized care to improve survival rates. MATERIAL AND METHODS: This retrospective study investigates four nutritional scores and laboratory parameters' predictive significance concerning postoperative mortality after surgical treatment of proximal femur fractures at 1, 3, 6, and 12 month/s for patients over 60 years using the chi-square test, Cox regression analysis, and receiver operating characteristics (ROC). The European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines were used as part of the screening of the respective nutritional status of the patients, in particular to filter out malnutrition. RESULTS: A total of 1080 patients were included in this study, whereas 8.05% suffered from malnutrition, defined as a body mass index (BMI) below 18.5 kg/m2. The Mini Nutritional Assessment (MNA) screening tool identified the highest proportion of malnourished patients at 14.54%. A total of 36.39% of patients were at risk of malnutrition according to three nutrition scores, with MNA providing the most significant proportion at 41.20%. Patients identified as malnourished had a higher mortality rate, and MNA screening was the only tool to show a significant correlation with postoperative mortality in all survey intervals. The MNA presented the best predictive significance among the screening tools, with a maximum area under the curve (AUC) of 0.7 at 12 month postoperatively. CONCLUSIONS: MNA screening has a solid correlation and predictive significance regarding postoperative mortality-therefore routine implementation of this screening in orthopedic/traumatology wards is recommended. Moreover, nutritional substitution therapy can offer a relatively inexpensive and easy-to-implement measure. The Graz malnutrition screening (GMS) shows moderate predictive power and could be considered as an alternative for patients under 60 years of age. A higher albumin level is associated with improved survival probability, but cannot be indicative of nutritional status.

BACKGROUND: The COVID-19 pandemic has had a significant impact on the treatment protocols of orthopedic and trauma departments, but its specific effect on the mortality of hip fracture patients due to possible delays in surgery remains uncertain. This study aimed to investigate whether the COVID-19 pandemic worsened the mortality of patients with hip fractures. MATERIALS AND METHODS: This study included 246 prospectively enrolled patients who suffered from hip fractures during the Austrian State of Emergency period between 1 March and 30 June 2020 and 2021 and were admitted to a tertiary care trauma center. This cohort was compared with a retrospective control group of 494 patients admitted for hip fractures during the same timeframe in 2017, 2018, and 2019. These groups were compared to a prospective recruited "post-COVID-19 collective consisting of the years 2022 and 2023 including 313 patients. RESULTS: This study found a 22% reduction in admissions during the COVID-19 period compared to the pre-COVID period (p = 0.018), as well as significant changes in gender (p = 0.013) and place of accident (p = 0.049). No other changes in demographic variables were observed. The 30-day mortality rate was 14.67% in the pre-COVID period, compared to 15.18% during the COVID-19 period (p = 0.381). No differences were observed in surgical complication rates or in the relationship between comorbidity burden and survival. CONCLUSION: This study did not show a higher perioperative mortality rate due to COVID-19. However, under current circumstances, with potentially reduced surgical and hospital bed capacities, it is expected that this condition might require a high degree of resources in times when resources are potentially scarce, such as during an ongoing pandemic. LEVEL OF EVIDENCE: Level III.
RESUMO
Inferior shoulder dislocation in fixed abduction, also known as luxatio erecta humeri (LEH), is a rare injury with little data available. Therefore, the primary aim of this study was to evaluate and present our case series of this type of injury with special emphasis on associated pathologies; the secondary aim was to present diagnostic recommendations to detect for potential associated pathologies typically seen with this injury. A total of 38 patients (13 females, average age 72.8 years and 25 males, average age 41.4 years), who have been treated for inferior shoulder dislocation between 1992 and 2020, were included in this study. Associated pathologies after LEH were found in 81% of the cases. Twenty-one of these patients presented with secondary bony pathologies. Six patients revealed rotator cuff injuries diagnosed by magnetic resonance imaging (MRI). Seven patients exhibited pathological findings at the capsule-ligament complex. Eight patients presented with neurological findings. All neurologic symptoms except one axillary nerve palsy and a radialis paresis dissolved during the follow-up period. Five patients received surgical treatment of the affected shoulder. Inferior shoulder dislocation is a rare condition presenting with a high number of associated injuries. According to the findings of the present study, we want to raised awareness of the high rate of potential secondary shoulder pathologies associated with LEH. Beside a thorough clinical examination and immediate standard radiographs in two planes, we recommend to perform computed tomography scanning and an MRI of the shoulder as soon as possible. In the case of neurologic deficiencies, a determination of nerve conduction should be performed.
RESUMO
The COVID-19 pandemic and the resulting restrictions led to a reduced number of surgeries. This study examines its impact on the course of treatment and clinical outcome of surgically treated paediatric upper limb fractures during that specific period. This retrospective cohort study evaluated all children aged 0-18 years presenting with an upper limb fracture treated surgically at the level 1 trauma centre of the University Clinic of Orthopaedics and Trauma Surgery of Vienna within lockdown from 16 March to 29 May 2020 (definition applied through corresponding legislation) compared to the same period from 2015 to 2019. A total number of 127 children (m:63; f:44) were included. The lockdown did not lead to a significant increase in complications during and after initial surgery. Time until removal of implant was not significantly prolonged (p = 0.068; p = 0.46). The clinical outcome did not significantly differ compared to previous years. The experience of a level 1 trauma centre showed that despite reduced surgical capacity during the COVID-19 pandemic, no negative differences concerning course of treatment and clinical outcome of surgically treated paediatric upper limb fractures were present. These findings are still of importance since the COVID-19 pandemic continues and several countries in Central Europe are currently under their fourth lockdown.
RESUMO
The aim of this study was to retrospectively evaluate the risk of acute hemorrhagic complications in patients after either a decompressive craniectomy or a craniotomy sustaining a recurrent mild traumatic brain injury. Furthermore, we analyze whether there is a higher risk for acute hemorrhagic complications considering patients with anticoagulation compared with patients without anticoagulation in both groups. All patients with mild traumatic brain injuries after either decompressive craniectomy or craniotomy, treated between January 2005 and December 2020 at a single level 1 trauma center, were included in this retrospective analysis. Patients were screened for intracranial bleeding after mild traumatic brain injury with computed tomography. Additionally, the type of anticoagulation and its relationship concerning the clinical outcome were assessed. A total of 188 patients who had sustained a mild traumatic brain injury were included in the study. Overall, 22 patients (11.7%) presented intracranial lesions. A bony defect (decompressive craniectomy) was present in 31 patients (16.5%). In 157 patients (83.5%) who underwent decompressive craniectomy, the bony defect was closed during a second operation. There was no significant correlation between both groups on the occurrence of intracranial bleeding (p = 0.216). Furthermore, no difference was present between patients with and without anticoagulation (p = 0.794) concerning acute hemorrhagic complications after recurrent traumatic brain injury. Pre-existing bony defects after decompressive craniectomy showed no higher risk for acute hemorrhagic complications after recurrent mild traumatic brain injury compared with patients who primarily underwent craniotomy. Anticoagulation did not influence the occurrence of intracranial bleeding after mild traumatic brain injury in patients with decompressive craniectomy.

BACKGROUND: Various approaches have been used to evaluate callus stiffness in distraction osteogenesis. This assessment becomes even more critical as inadequate corticalization and premature removal of the frame lead to bending, refracture, and loss of length. This study aimed to verify the objective Pixel Value Ratio (PVR) and define an evaluation scheme to assess callus tissue development during internal and external bone lengthening. HYPOTHESIS: There are no differences between subjective parameters and objective evaluation for external and internal bone lengthening. PATIENTS AND METHODS: We included 24 patients in this retrospective study, treated by distraction osteogenesis of the lower limb. Ten patients were treated with external ring fixators and 14 with intramedullary lengthening devices. The minimum distraction distance was 3cm. Callus tissue was evaluated with the PVR, using digital X-rays during and after treatment. We combined this method with subjective evaluation parameters, including the continuity, signal intensity, and the regeneration tissue's homogeneity, presented in the X-ray Evaluation System for Distraction Osteogenesis (XESDO). RESULTS: The subjective evaluation showed an increase of continuity and signal-intensity between 4th postoperative weeks and complete healing with significant differences between the external and internal groups for homogeneity only after four weeks and for all parameters at 3C (p<0.05). The PVR showed an increase during consolidation with values between 0.7 and 1.0 for both groups with almost perfect interobserver agreement. Significant lower values were found in the anterior tibial cases. CONCLUSION: PVR appears to be a practical tool for radiological evaluation of callus tissue development. In combination with the newly introduced XESDO and the surgeon's experience, these methods can be helpful for decisions during all phases of distraction osteogenesis. It is important for adapting alignment or distraction-rate, as various potential complications can be detected early. However, further studies are necessary to assess the image-based determination of callus tissue stability. LEVEL OF EVIDENCE: III; cohort study.

Computed tomography (CT) is an essential tool in orthopedic surgery but is known to be a method with that entails radiation exposure. CT increases the risk of developing fatal cancer, which should not be underestimated. However, patients with bone defects and/or deformities must frequently undergo numerous investigations during their treatment. CT is used for surgical planning, evaluating callus maturation, alignment measurement, length measurement, torsion measurement, and angiography. This study explores the indications in CT scans for limb lengthening and deformity correction and estimates the effective radiation dose. These results should help avoid unnecessary radiation exposure by narrowing the examination field and by providing explicit scanning indications. For this study, 19 posttraumatic patients were included after the bone reconstruction of 21 lower limbs. All patients underwent CT examinations during or after treatment with an external ring fixator. The mean effective dose was 3.27 mSv, with a mean cancer risk of 1:117,014. The effective dose depended on the location and indication of measurement, with a mean dose of 0.04 mSv at the ankle up to 6.8 mSv (or higher) for vascular depictions. CT evaluation, with or without 3D reconstruction, is a crucial tool in complex bone reconstruction and deformity treatments. Therefore, strict indications are necessary to reduce radiation exposure-especially in young patients-without compromising the management of their patients.
RESUMO
BACKGROUND: Distraction osteogenesis with an intramedullary motorized nail is a well-established method to treat leg length discrepancy (LLD). The complex process of bone consolidation is affected by age, location, comorbidities, smoking and gender. The purpose of this case series was to investigate influencing factors in bone regeneration after intramedullary callus distraction. HYPOTHESIS: Advanced age influences the outcome of intramedullary limb lengthening. PATIENTS AND METHODS: This retrospective analysis included 19 patients after intramedullary telescopic nailing (PRECICE) on the lower limb with a mean age of 43 years. Bone healing was assessed by distraction and healing parameters such as distraction-consolidation time (DCT), distraction index (DI), healing index (HI), lengthening index (LI), and consolidation index (CI). RESULTS: Confounding factors such as smoking, previous operations on the treated bone, but also the occurrence of complications, and the number of revision surgeries are independent of the patients' age. Younger patients showed a shorter distraction distance, a lower DCT, a lower DI, a higher HI, and a higher CI than older patients. The complication rate requiring nail exchange was higher among the younger patients. Bony healing was observed in all age groups treated with a telescopic nail regardless of age. CONCLUSION: Advanced age did not influence bone healing or complication rate in intramedullary lengthening. However, the conclusion is limited by the small patient number. LEVEL OF EVIDENCE: IV; Case control study.

PURPOSE: This study aims to elucidate the occurrence of postoperative carpal tunnel syndrome (CTS), the functional outcome of patients with primary pronator teres syndrome (PTS), and review complete literature regarding this topic. MATERIAL AND METHODS: A retrospective chart review was conducted in patients with PTS at a single center. In all patients, a numeric Visual Analog Scale (VAS) score, Pinch-Test, Jamar hand dynamometer test (JAMAR), and the Disabilities of the Arm Shoulder and Hand (DASH) score were analyzed preoperatively and at final follow-up to assess outcome. Additionally, a complete review of the literature was performed, including all data dealing with pronator teres syndrome. RESULTS: Ten female and two male patients were included with a mean age of 49 years. Significant improvement in DASH and numeric VAS was detected at latest postoperative follow-up. In three patients, clinical signs of CTS pathology were detected during the follow-up period. One patient needed to be treated surgically, and in the other two patients, a conservative management was possible. In one patient (8%), a PTS recurrence was detected. All patients presented satisfied at latest follow-up. CONCLUSION: In one-fourth of our patients, a CTS occurred during the follow-up period. Therefore, focusing on double-crush syndrome in unclear or mixed symptoms is necessary to avoid multiple operations. Furthermore, it seems that assessment with NCV is not enough for diagnosing PTS; therefore, further research is needed to clarify this problem.
