Aims: The primary objective of this study was to develop a validated classification system for assessing iatrogenic bone trauma and soft-tissue injury during total hip arthroplasty (THA). The secondary objective was to compare macroscopic bone trauma and soft-tissues injury in conventional THA (CO THA) versus robotic arm-assisted THA (RO THA) using this classification system., Methods: This study included 30 CO THAs versus 30 RO THAs performed by a single surgeon. Intraoperative photographs of the osseous acetabulum and periacetabular soft-tissues were obtained prior to implantation of the acetabular component, which were used to develop the proposed classification system. Interobserver and intraobserver variabilities of the proposed classification system were assessed., Results: The BOne trauma and Soft-Tissue Injury classification system in total Hip arthroplasty (BOSTI Hip) grades osseous acetabular trauma and periarticular muscle damage during THA. The classification system has an interclass correlation coefficient of 0.90 (95% CI 0.86 to 0.93) for interobserver agreement and 0.89 (95% CI 0.84 to 0.93) for intraobserver agreement. RO THA was associated with improved BOSTI Hip scores (p = 0.002) and more pristine osseous surfaces in the anterior superior (p = 0.001) and posterior superior (p < 0.001) acetabular quadrants compared with CO THA. There were no differences between the groups in relation to injury to the gluteus medius (p = 0.084), obturator internus (p = 0.241), piriformis (p = 0.081), superior gamellus (p = 0.116), inferior gamellus (p = 0.132), quadratus femoris (p = 0.208), and vastus lateralis (p = 0.135), but overall combined muscle injury was reduced in RO THA compared with CO THA (p = 0.023)., Discussion: The proposed BOSTI Hip classification provides a reproducible grading system for stratifying iatrogenic bone trauma and soft-tissue injury during THA. RO THA was associated with improved BOSTI Hip scores, more pristine osseous acetabular surfaces, and reduced combined periarticular muscle injury compared with CO THA. Further research is required to understand if these intraoperative findings translate to differences in clinical outcomes between the treatment groups., Competing Interests: F. S.

Shaft fractures of the tibia and fibula mainly affect younger patients and are therefore of great socioeconomic importance. Due to the high proportion of high-energy direct trauma mechanisms and the thin soft tissue covering layer of the ventromedian tibia, open factures occur in up to 39%. A structured diagnostic and therapeutic approach is essential for successful treatment. Reamed intramedullary nailing is currently the gold standard surgical procedure. The suprapatellar approach, representing an interesting alternative to the popular infrapatellar approach, postoperative complications, such as anterior knee pain as well as the management of non-unions are discussed in this article. Furthermore, the indications and the application of minimally invasive plate osteosynthesis (MIPO) and external fixators are described. Every trauma surgeon should be familiar with the etiology and the surgical treatment of compartment syndrome. A firm knowledge of the classifications of open and closed soft tissue injury is mandatory.

The objective of this study was to evaluate interobserver reliability and the concurrent criterion validity of the adapted version of the International Skin Tear Advisory Panel (ISTAP) Skin Tear Classification System to Brazilian Portuguese. For the evaluation of interobserver reliability using the photograph database, 36 nurses classified 30 skin tears (STs) into three groups, according to its definitions (adapted version). For the evaluation through clinical application, 23 nurses classified 12 STs present in 8 thoracic and cardiovascular postoperative patients at a tertiary hospital in Sao Paulo, Brazil. For the data collection of patients, an enterostomal therapist nurse classified the ST found by simultaneously using the adapted ISTAP version and the Skin Tear Audit Research (STAR) Classification System to test the concurrent criterion validity. The average of 17.83 correct answers (SD = 5.03) resulted from 1080 photograph observations, with Fleiss κ = 0.279 (reasonable concordance level). The interobserver reliability in the clinical application resulted in a global correct answer percentage of 76.7% in 85 observations. The concurrent criterion validity was attested by the total correlation (r = 1) between ISTAP and STAR. The ISTAP classification for ST is a reliable instrument and also valid in Brazil, making it another option to be used in clinical practice., (© 2019 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)

Whiplash is the most common injury reported in low-velocity impact road traffic accidents, but claimants report a range of other soft tissue injuries and we looked at the prevalence of these and any patterns. We retrospectively reviewed reports from the medico-legal practice of an orthopaedic surgeon. We collected data on 609 claimants. Sixty-two per cent were women (p < 0.0001). Majority (90.3%) reported an injury to at least one other area than neck, and 48% of claimants reported shoulder pain. Hand/wrist injuries were almost exclusive to drivers (p = 0.0013). Those with knee injuries were older than those without (p = 0.001). There was a significant difference in the age of patients with different spinal injury patterns (p < 0.0001). Occupational status did not appear to influence the pattern of injuries (p = 0.06). Psychological symptoms were associated with a greater number of body parts injured (p < 0.01). Our data confirm a strong association between these soft tissue injuries and psychological symptoms.

Aim: This study proposed to (1) develop a metric graduated colour tool and (2) demonstrate the effectiveness of the tool for use in the assessment of neonatal skin injuries., Materials/methods: Findings from wound literature informed the metric graduated colour tool's development. Tool development included consideration of colours, size (comparative to neonatal skin injuries), cost, materials, feasibility and suitability for the neonatal clinical setting. Assessment of the tool's applicability with clinical images was then tested using digital cameras with specific evaluation of image sharpness and colour. Further evaluation was conducted within a case series of neonatal skin injuries., Results: The metric graduated colour tool comprised of 15 colours, measures 60 mm, displays metric dimensions, and offers a discernible reference for clinical images and injury/wound bed comparison. Images collected appeared enhanced with clear wound edges compared to previous methods. Four neonates who acquired skin injuries were included in the case series for which the tool provided reliable metric and colour comparison of epidermal stripping, extravasation, birth injury, and pressure injury. When used to compare injury assessments for series subjects measurements of both increased and decreased severity were obtained., Conclusion: A metric and colour tool can be used in conjunction with digital photographs to enhance objective assessment of neonatal skin injuries/wounds. The metric and colour tool provides the foundation for vital skin injury assessment and documentation essentials including injury bed colour, size and consideration of depth of damage., (Copyright © 2019 Tissue Viability Society.

Spinal traumas represent a significant proportion of muscle-skeletal injuries worldwide. Spinal injuries involve a complex structure with components having different traumatic susceptibility and variable healing capabilities. The interaction of numerous variables at time of trauma creates a great variety of lesions which makes challenging the creation and comparison of homogeneous groups, with difficulties in classifying spinal lesions, in assessing their instability, and in defining the indication and outcome of different treatment strategies. The evolution of concepts on instability has accompanied that of traumas classification schemes and treatment strategies. The assessment of instability in a spinal injury is actually crucial in front of newer surgical techniques and hardwares. Despite a long history of attempts to classify spinal traumas, it remains some degree of controversy in describing imaging data and a wide variety of treatment strategies. Acute cervical spine injuries affect from 1.9% to 4.6% of subjects reporting a blunt trauma, and up to 5.9% of multiple-injured patients. Most of spinal cord injuries are a consequence of unstable fractures of the cervical spine. An accurate and early diagnosis is mandatory to prevent neurological damage in unstable fractures. Classic and newer classifications are primarily based on features identifiable by using conventional imaging and CT scan, which are the most available modalities at most trauma centers. Even though multidetector-CT remains superior in assessing with high accuracy bone injuries, MRI is the most sensitive modality for detecting soft tissues injuries and spinal cord damage., (Copyright © 2019 Elsevier B.V.

Background: The surgical treatment of chronic ankle instability (CAI) relies chiefly on anterior talo-fibular ligament (ATFL) repair (with or without augmentation) or anatomical reconstruction with a tendon graft. Arthroscopy enables not only a complete assessment and the same-stage treatment of concomitant articular lesions, but also an accurate assessment of ligament lesions. Pre-operative imaging studies (MRI, CT, US) may fail to provide sufficient detail about chronic ATFL lesions to guide the decision between repair and reconstruction. The aim of this study was to develop an arthroscopic classification of chronic ATFL lesions designed to assist in selecting the optimal surgical technique., Material and Methods: Sixty-nine anterior ankle arthroscopy videos recorded before surgery for CAI were studied retrospectively. ATFL dissection was performed in all patients. Based on the video analysis, five ATFL grades were identified: 0, normal ATFL thickness and tension; 1, ATFL distension with normal thickness; 2, ATFL avulsion with normal thickness; 3, thin ATFL with no resistance during the hook test; and 4, no ATFL, with a bald malleolus. Intra- and interobserver reproducibility of the arthroscopic classification of chronic ATFL lesions was evaluated by computing the kappa coefficients (κ) after assessment by two independent observers., Results: All 69 ATFLs were classified as abnormal (none was grade 0). Each ATFL could be matched to a grade. Intra-observer agreement was good for both observers: κ was 0.67 with 75% of agreement for one observer and 0.68 with 76% of agreement for the other observer. Inter-observer agreement was fair to good, with κ values ranging from 0.59 to 0.88 and agreement from 70% to 91%., Discussion: Arthroscopic ATFL dissection is a simple procedure that provides a highly accurate assessment of ATFL lesions and mechanical resistance, focussing chiefly on the superior ATFL. Grade 1 and 2 lesions can be repaired using the Broström-Gould procedure, whereas grade 3 and 4 lesions require anatomic reconstruction with grafting., Conclusion: This arthroscopic classification of chronic ATFL lesions confirms the diagnostic role for arthroscopy in assessing the ligaments in patients with CAI. It is helpful for determining the best surgical technique for stabilising the ankle. These results must be confirmed in a larger study., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)

Background: Imaging studies done to evaluate chronic ankle instability (CAI) often fail to accurately detail injuries to the anterior talo-fibular ligament (ATFL) and may, therefore, also fail to provide guidance for selecting the most appropriate surgical procedure. Arthroscopy is now an indispensable tool for accurately diagnosing ATFL injuries. This study looked at agreement between arthroscopy and imaging study assessments of ATFL injuries. The primary objective was to adapt an arthroscopic classification of chronic ATFL lesions to the pre-operative imaging study findings in order to estimate the performance of computed tomography (CT)-arthrography, ultrasonography, and magnetic resonance imaging (MRI) in diagnosing ATFL lesions, using arthroscopy as the reference standard., Hypothesis: Agreement between arthroscopic and imaging findings of chronic ATFL injuries can be assessed by using a shared classification developed from the arthroscopic evaluation, used as the reference standard., Material and Methods: A prospective multicentre study was conducted in 286 patients with arthroscopically-treated CAI. In each patient, the arthroscopic assessment of the ATFL was compared to the pre-operative findings by CT-arthrography, ultrasonography, and MRI. A classification of ATFL lesions based on the arthroscopic assessment was used to analyse the imaging studies. Using this classification, two independent observers compared the findings and evaluated the agreement between arthroscopy and imaging studies., Results: Of the 286 patients, 157 had complete information on the arthroscopic assessment and on pre-operative imaging studies and were included in the analysis. Imaging studies were CT-arthrography in 49 patients, ultrasonography in 63 patients, and MRI in 45 patients; both ultrasonography and MRI were performed in 3 patients. Agreement with arthroscopy was 82% and 88.5% for CT-arthrography, 66.7% and 76.2% for ultrasonography, 70.5% and 79.5% for MRI, and 73.4% and 81.2% for all imaging studies pooled., Discussion: Arthroscopy plays a crucial role in the definitive assessment of ligament lesions in patients with CAI, as it supplies far more accurate information than any of the current imaging studies and, in addition, provides a dynamic evaluation of the ligaments and assesses mechanical strength. In the study population, a simple arthroscopic evaluation consistently visualised ATFL lesions, thereby either correcting or confirming the pre-operative imaging study findings. Importantly, the arthroscopic assessment provided more accurate information on the lesions and quality of the ATFL compared to the imaging studies. Arthroscopy has improved our knowledge of chronic ATFL lesions and allowed the development of a simple but accurate four-grade classification of direct relevance to choosing the optimal therapeutic procedure. This classification must be disseminated among radiologists to improve the diagnostic performance of pre-operative imaging studies, assist surgeons in selecting the most appropriate ankle-stabilising procedure, and improve patient information. Further studies are needed to confirm the promising results reported here and the usefulness of this common arthroscopy and imaging-study classification for chronic ATFL lesions., Level of Evidence: II., (Copyright © 2018 Elsevier Masson SAS.

Background: The objective of this study was to compare macroscopic bone and soft tissue injury between robotic-arm assisted total knee arthroplasty (RA-TKA) and conventional jig-based total knee arthroplasty (CJ-TKA) and create a validated classification system for reporting iatrogenic bone and periarticular soft tissue injury after TKA., Methods: This study included 30 consecutive CJ-TKAs followed by 30 consecutive RA-TKAs performed by a single surgeon. Intraoperative photographs of the femur, tibia, and periarticular soft tissues were taken before implantation of prostheses. Using these outcomes, the macroscopic soft tissue injury (MASTI) classification system was developed to grade iatrogenic bone and soft tissue injuries. Interobserver and Intraobserver validity of the proposed classification system was assessed., Results: Patients undergoing RA-TKA had reduced medial soft tissue injury in both passively correctible (P < .05) and noncorrectible varus deformities (P < .05); more pristine femoral (P < .05) and tibial (P < .05) bone resection cuts; and improved MASTI scores compared to CJ-TKA (P < .05). There was high interobserver (intraclass correlation coefficient 0.92 [95% confidence interval: 0.88-0.96], P < .05) and intraobserver agreement (intraclass correlation coefficient 0.94 [95% confidence interval: 0.92-0.97], P < .05) of the proposed MASTI classification system., Conclusion: There is reduced bone and periarticular soft tissue injury in patients undergoing RA-TKA compared to CJ-TKA. The proposed MASTI classification system is a reproducible grading scheme for describing iatrogenic bone and soft tissue injury in TKA., Clinical Relevance: RA-TKA is associated with reduced bone and soft tissue injury compared with conventional jig-based TKA. The proposed MASTI classification may facilitate further research correlating macroscopic soft tissue injury during TKA to long-term clinical and functional outcomes., (Copyright © 2018 Elsevier Inc.

The extensor mechanism of the knee-consisting of the four muscles of the quadriceps, the quadriceps tendon, the patella, and the patellar ligament-is essential for lower extremity function during both standing and ambulation. The presence of articular cartilage and growing physes in the pediatric knee, coupled with the generation of significant tensile force, creates an opportunity for pathology unique to the pediatric population.Tibial tubercle fractures and patella injuries are quite rare, and even pediatric-trained orthopaedic surgeons may not be exposed to these injuries on a regular basis. It is the intent of this article to discuss the current literature regarding the mechanism of injury, diagnostic workup, classification, indications for surgical versus non-surgical management, and techniques for operative management for both tibial tubercle and patella (transverse and sleeve) fractures., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Due to the exposure of the hands in the daily routine, defect wounds of the hand are common. The injury severity varies and ranges from small fingertip defects to large soft tissue lesions with exposed tendons, nerves and vessels. The complete extent of the soft tissue defect is often only recognizable after meticulous debridement. A considerable variety of techniques for defect coverage are available to the surgeon but the actual challenge is to select the most appropriate procedure which will result in the smallest possible residual defect. This review article presents the diagnostic approaches to soft tissue defects of the hand and current treatment options.

Due to recent rampage and terror attacks in Europe, gunshot wounds have become a focus of attention even though they are still rare in Europe. Approximately 50% of gunshot wounds affect the extremities and to understand the sequelae, a basic knowledge of wound ballistics is indispensable. The energy transmitted from the bullet to the tissue is responsible for the severity of the injury and is dependent on the type of weapon and ammunition. A differentiation is made between low-energy injuries caused, e.g. by pistols and high-energy injuries mostly caused by rifles. The higher energy transfer to the tissue in high-energy injuries, results in a temporary wound cavity in addition to the permanent wound channel with extensive soft tissue damage. High-energy gunshot fractures are also more extensive compared to those of low energy injuries. Debridement seems to be necessary for almost all gunshot wounds. Fractures should be temporarily stabilized with an external fixator due to contamination.

Intraarticular fractures of the distal tibia (pilon fractures) are rare injuries and today they occur mostly in traffic accidents and falls from a great height. There are simple fractures in the context of low-energy traumas, as well as complex comminuted fractures in high-energy traumas. Besides the clinical examination, plain radiographs and computed tomographic scans are diagnostic prerequisites. The aim of the diagnostic process is to clearly identify and classify the fracture before appropriate treatment is initiated. The systems used to classify the displaced distal pilon fractures are supposed to ensure the three-dimensional assessment of the fracture and provide high inter- and intra-observer agreement. In addition to the classification of Rüedi and Allgöwer, the classification of pilon fractures has been carried out using the AO classification.

Objective: To assess and compare the intra- and interrater reliability of three different MRI grading and classification systems after acute hamstring injury., Methods: Male athletes (n=40) with clinical diagnosis of acute hamstring injury and MRI ≤5days were selected from a prospective cohort. Two radiologists independently evaluated the MRIs using standardised scoring form including the modified Peetrons grading system, the Chan acute muscle strain injury classification and the British Athletics Muscle Injury Classification. Intra-and interrater reliability was assessed with linear weighted kappa (κ) or unweighted Cohen's κ and percentage agreement was calculated., Results: We observed 'substantial' to 'almost perfect' intra- (κ range 0.65-1.00) and interrater reliability (κ range 0.77-1.00) with percentage agreement 83-100% and 88-100%, respectively, for severity gradings, overall anatomical sites and overall classifications for the three MRI systems. We observed substantial variability (κ range -0.05 to 1.00) for subcategories within the Chan classification and the British Athletics Muscle Injury Classification, however, the prevalence of positive scorings was low for some subcategories., Conclusions: The modified Peetrons grading system, overall Chan classification and overall British Athletics Muscle Injury Classification demonstrated 'substantial' to 'almost perfect' intra- and interrater reliability when scored by experienced radiologists. The intra- and interrater reliability for the anatomical subcategories within the classifications remains unclear., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Parallel reimbursement regimes, under which providers have some discretion over which payer gets billed for patient treatment, are a common feature of health care markets. In the U.S., the largest such system is under Workers' Compensation (WC), where the treatment workers with injuries that are not definitively tied to a work accident may be billed either under group health insurance plans or under WC. We document that there is significant reclassification of injuries from group health plans into WC, or "claims shifting", when the financial incentives to do so are strongest. In particular, we find that injuries to workers enrolled in capitated group health plans (such as HMOs) see a higher incidence of their claims for soft-tissue injuries (which are hard to classify specifically as work related) under WC than under group health, relative to those in non-capitated plans. Such a pattern is not evident for workers with traumatic injuries. Moreover, we find that such reclassification is more common in states with higher WC fees, once again for soft tissue but not traumatic injuries. Our results imply that a significant shift towards capitated reimbursement, or reimbursement reductions, under GH could lead to a large rise in the cost of WC plans., (Copyright © 2016 Elsevier B.V.

Background: Maxillofacial fractures occur in a significant proportion worldwide and can occur as an isolated injury or in combination with other severe injuries including cranial, spinal, and upper and lower body injuries requiring prompt diagnosis with possible emergency interventions. The epidemiology of facial fractures varies with regard to injury type, severity, and cause and depends on the population studied. Hence, understanding of these factors can aid in establishing clinical and research priorities for effective treatment and prevention of these injuries., Materials and Methods: In this present retrospective study, we provide a comprehensive overview regarding cranio-maxillofacial trauma on 3611 patients to assist the clinician in assessment and management of this unique highly specialized area of traumatology. A preformed pro forma was used to analyze the medical records of patients treated for facial trauma in The Department of Oral and Maxillofacial Surgery, Meenakshi Ammal Dental College and Hospital, Chennai. The distribution according to age, gender, etiology, type of injury, time interval between accident and treatment, loss of consciousness, facial bones involved, pattern of fracture lines, treatment offered, and postoperative complications were recorded and evaluated., Results: We inferred male patients sustained more injuries mostly in the third decade of age. Road traffic accidents were the most common cause of injury. Mandible was the most commonly fractured bone in the facial skeleton. Soft tissue injuries occurred more in road traffic accidents and upper lip was the commonest site of injury., Conclusion: Our study provides insights into the epidemiology of facial injuries and associated factors and can be useful not only in developing prevention strategies but also for grading the existing legal regulations and also for framing a more effective treatment protocol.

Background: A broad range of systemic complications has been described to occur in patients with open major fractures. Various causes have been claimed to play a role. We therefore surveyed a nationwide trauma registry to assess risk factors associated with closed and various types of open femur fractures., Methods: This was a cohort study in a nationwide population-based prospective database. Inclusion criteria for selection from database are as follows: individuals with femur fracture, age 16 years or older, and survival until primary admission. Main groups included closed and open femur fracture. Patient demographics, injury severity (New Injury Severity Score), surgical fracture management, length of stay, and systemic complications (e.g., multiple organ failure [MOF], sepsis, mortality) were collected and statistically analyzed using SPSS statistics. Multivariate regression analysis was performed to stratify subgroups for the degree of open soft-tissue injury according to Gustilo and Anderson., Results: Among 32,582 documented trauma victims (January 1, 2002, to December 31, 2010), a total of 5,761 met the inclusion criteria. Main groups: 4,423 closed (76.8%) and 1,338 open femur fractures (23.2%). Open fractures subgroups were divided into I° (334, 28.1%), II° (526, 44.3%), and III° (328, 27.6%). Open fractures were associated with an increased risk of prehospital hemorrhagic shock (p = 0.01), higher resuscitation requirements (p < 0.001), MOF (p = 0.001), and longer in-hospital (p < 0.001) and intensive care stay (p = 0.001). While New Injury Severity Score values showed a minor increase per subgroup, the prevalence of MOF, sepsis, and mortality multiplied with the degree of open soft-tissue injury. Especially patients with Type III open femur fractures received mass transfusions (28.2%, p < 0.001), and mass transfusions were identified as independent predictor for sepsis (odds ratio [OR], 2.393; 95% confidence interval [CI], 1.821-3.143; p < 0.001) and MOF (OR, 2.966; 95% CI, 2.409-3.651; p < 0.001). Our data also indicate an increased mortality in patients with open femur managed outside Level I trauma centers (OR, 1.358; 95% CI, 1.018-1.812; p = 0.037)., Conclusion: Open femur fractures are associated with higher in-hospital complications related to incidence of MOF, associated intensive care unit stay, and hospital days when compared with closed femur fractures. For prevention of in-hospital complications, prompt hemorrhage control, surgical fracture fixation, cautious blood management, and triage to a Level I trauma center must be considered., Level of Evidence: Epidemiologic/prognostic study, level II.

Background: The British Athletics Muscle Injury Classification describes acute muscle injuries and their anatomical site within muscle based on MRI parameters of injury extent. It grades injuries from 0 to 4 and classifies location based on a myofascial (a), musculotendinous (b) or intratendinous (c) description. This is a retrospective cohort study that assessed time to return to full training (TRFT) and injury recurrence in the different British Athletics classifications for hamstring injuries sustained by elite track and field (T&F) athletes over a 4-year period., Methods: The electronic medical records (EMRs) of 230 elite British T&F athletes were reviewed. Athletes who sustained an acute hamstring injury, with MRI investigation within 7 days of injury, were included. MRI were graded by two musculoskeletal radiologists using the British Athletics Muscle Injury Classification. The EMRs were reviewed by 2 sports physicians, blinded to the new classification; TRFT and injury recurrence were recorded., Results: There were 65 hamstring injuries in 44 athletes (24±4.4 years; 28 male, 16 female). TRFT differed among grades (p<0.001). Grade 3 injuries and 'c' injuries took significantly longer and grade 0 injuries took less TRFT. There were 12 re-injuries; the injury recurrence rate was significantly higher in intratendinous (c) injuries (p<0.001). There was no difference in re-injury rate between number grades 1-3, hamstring muscle affected, location (proximal vs central vs distal), age or sex., Conclusions: This study describes the clinical application of the British Athletics Muscle Injury Classification. Different categories of hamstring injuries had different TRFT and recurrence rate. Hamstring injuries that extend into the tendon ('c') are more prone to re-injury and delay TRFT., (Published by the BMJ Publishing Group Limited.

Purpose: To verify the clinical applicability of a modified classification system in distractive-extension cervical spine injury that reflects the degrees of soft tissue damage and spinal cord injury while complementing previous Allen classification and subaxial cervical spine injury classification (SLIC) system., Methods: A total of 195 patients with cervical spine distraction-extension (DE) injury were retrospectively classified. We added stages IIIA (with concomitant spinal cord injury without bony abnormalities) and IIIB (with concomitant additional soft tissue swelling) to the existing stages I and II of the Allen classification. We also supplemented the SLIC system by refining and assigning scores to bony morphology and soft tissue damage. The previous and proposed classification systems were compared by analyzing their scoring performances in terms of clinical features and prognosis., Results: The Allen classification yielded 153 and 42 patients with stage 1 and 42 stage 2 injuries, respectively. Patients classified according to the proposed system were stratified as follows: stage I, 58; stage II, 27; stage IIIA, 33; and stage IIIB, 77. Regarding neurological symptoms and prognosis, stages IIIA and IIIB were poorer than stage I but significantly better than stage II (P < 0.05). On the SLIC system, 146 patients scored ≥5; and 37 and 12 patients scored 4 and ≤3 points, respectively, whereas the numbers of patients who scored ≥5, 4, and ≤3 points on the modified SLIC system were 170, 21, and 4, respectively., Conclusions: The proposed classification and scoring system to complement the Allen classification and SLIC system with respect to the degrees of soft tissue damage and spinal cord injury is considered effective for diagnosing and determining therapeutic directions and prognosis in cases of cervical spine extension injury.

The number of injuries caused by dog bites is increasing in the United Kingdom. We review patients admitted with dog bites to a single maxillofacial department in a district general hospital over a 21-month period. Data include patients' characteristics, and the site and severity of injury. The relationship of the victim to the animal and its breed and classification were added where possible. In total, 65 patients, mean age 22 years (range 1-71, median 14) were included. There were 84 wounds, and their site and severity were recorded according to the Lackmann classification. Twelve different breeds of dog were responsible for the bites. An appreciable proportion of those injured were young children. Educational strategies should aim to reduce the incidence of all dog bites, particularly in young children, as their needs after initial treatment are complex. We propose specific strategies to reduce the number of these injuries., (Copyright © 2015 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.)

The goal of this study was to assess the incidence of soft tissue injury in the tibial plateau fracture by magnetic resonance image (MRI) and reveal the relationship between the articular widening/depression and the risk of meniscus and ligament disorder. A total of 54 patients with tibial plateau fracture were indicated for operative intervention. Soft tissue injuries were assessed by MRI. Meniscus, anterior/posterior cruciate ligaments and medial/lateral collateral ligaments injuries on MRI were evaluated. The articular widening/depression was measured in picture archiving and communication systems. Schatzker classification of fracture types was not significantly associated with soft tissue injuries. The rates of soft tissue injury in types IV and II (respectively, 85.7 and 74.1 %) were higher than those in other types. The meniscus injury was the most common soft tissue damage, and the incidence of meniscus injury was 55.6 %. When LPDCT and LPWCT were, respectively, about 7.6 mm and 10.1 mm and LPDX-ray and LPWX-ray, respectively, 5.6 and 7.4 mm, more attention should be paid on the collateral and cruciate ligament injuries in types I, II and III. Furthermore, when LPWCT and LPWX-ray were, respectively, about 10.3 and 8.6 mm, the collateral and cruciate ligaments were susceptible to injury in types IV and V. In conclusion, tibial plateau fracture can occur high morbidity of soft tissue injury, including meniscus and ligament disorder. X-ray and CT scan had different predicting standards for soft tissue injury, and the articular widening/depression in the tibial plateau was associated with meniscus and ligament injuries.

Skin Changes at Life's End (SCALE) wounds include wounds of many underlying etiologies that accompany the dying process. These wounds occur due to unmodifiable intrinsic and extrinsic factors unique to each individual. This article describes the case of a dying patient who sustained a skin tear that deteriorated into a SCALE wound that meets the criteria for a National Pressure Ulcer Advisory Panel unavoidable pressure injury.

Background: The study by Lauge-Hansen published in the Archives of Surgery in 1950 still stands as the seminal work for our understanding of the pathomechanics of ankle fractures. The purpose of the present study was to recreate Lauge-Hansen's experiments for the supination-external rotation (SER) fracture mechanism and to determine whether the predicted sequence of osseous and soft-tissue injury is reproducible on the basis of his originally described methodology., Methods: Ten fresh-frozen cadaver specimens amputated above the knee were utilized. The foot was axially loaded in a position of neutral dorsiflexion and supination. External rotation was applied manually in accordance with Lauge-Hansen's description until osseous and/or soft-tissue injury occurred. Fluoroscopic images were made and anatomic dissection was performed., Results: Although several specimens exhibited findings consistent with certain stages of the SER injury pattern, no specimen demonstrated the complete sequence of predicted osseous and soft-tissue injury., Conclusions: Loading cadaver specimens with an SER mechanism utilizing a methodology similar to that in the original experiments by Lauge-Hansen does not reliably produce the sequence of osseous and soft-tissue injury predicted by Lauge-Hansen., (Copyright © 2015 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: This study describes a modified classification and management protocol for perineal soft tissue injuries associated with pelvic fractures., Methods: A total of 11 patients with perineal soft tissue injuries associated with open pelvic fractures were studied retrospectively. The patients were classified into three types based on the area of defect: type A (urogenital zone), type B (anal zone), and type C (both urogenital and anal zones). Each type included the following subclasses: A1 (without urethra injuries), A2 (with urethra injuries), B1 (without anorectal injuries), B2 (with anorectal injuries), C1 (with types A1 and B1), C2 (with types A2 and B1), C3 (with types A1 and B2), and C4 (with types A2 and B2). The management protocol was planned according to the individual classifications. Protocol A1 (for type A1) involved skin graft or myocutaneous flap transplantation. Protocol A2 (for type A2) involved the same protocol combined with urine diversion. Protocol B1 (for type B1) involved skin graft or myocutaneous flap transplantation. Protocol B2 (for type B2) involved the same management combined with fecal diversion. Protocol C involved the correspondent protocol used for each subtype of type C., Results: Out of the 11 patients, there were 5, 3, and 3 cases of types A, B, and C, respectively. One patient died due to sepsis, and the wounds of the remaining patients healed well. No anal incontinence had occurred., Conclusions: Perineal soft tissue injuries associated with pelvic fractures can be classified into three types, and the management protocol can be planned according to the classification., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Intraarticular fractures of the distal tibia (pilon fractures) are caused by axial forces, usually in combination with torsional moments. Routine diagnostics include plain films and three dimensional (3D) imaging with computed tomography (CT). Treatment is often impaired by complex fracture configurations and thin soft tissue layers. The management of complex pilon fractures with soft tissue injuries has seen many trends, with changes toward staged protocols of temporary external fixation followed by delayed open reduction and internal fixation (ORIF), minimally invasive percutaneous plate osteosynthesis (MIPPO) techniques and special implants, the benefits of negative pressure wound sealing and early "fix and flap" efforts to reconstruct soft tissue defects. Reduction and fixation must involve respectful management and careful handling of soft tissues in order to minimize the well-known complications of this difficult fracture. The proper approach is one of the keys to success. Approach planning is based on the careful and thorough analysis of the fracture pattern in the 3D data set, which is the basis for a successful strategy for articular reconstruction.

Background: The soft tissues injury in periarticular fractures of the lower extremities determines the proper time to perform bone fixation., Objective: The aim of this study was to determine the intra and interobserver agreement in the Tscherne classification., Methods: This is a descriptive, prospective study for patients admitted to the Pablo Tobón Uribe Hospital (PTUH) with tibial plateau or tibial pilon fractures. We performed a standardize evaluation using video photography at the time of admission and 24, 48, and 72 h after admission. Fifteen five reviewers who had various levels of training produced a total of 1,200 observations. The intra- and interobserver agreement was assessed using a weighted kappa for multiple raters and more than two categories., Results: Twenty patients were admitted with tibial plateau and tibial pilon fractures. The intraobserver agreement for all 15 raters was kappa 0.81 (95% CI 0.79-0.83), and the interobserver agreement for all 15 raters was kappa 0.65 (95% CI 0.55-0.73). The interobserver agreement at 24 h was kappa 0.67 (95% CI 0.46-0.86)., Conclusions: Classifying the severity of soft tissue injury is critical in planning the surgical management of fractures of the lower extremities. Based on our results, we can reasonably argue that the Tscherne classification produced an adequate level of agreement and could be used to standardize and to guide the treatment, and to conduct research studies.
