Utilizing Low-cost Vacuum-assisted Closure as Adjuvant Therapy in Soft Tissue Reconstruction for a Mangled Upper Extremity

Summary: Soft tissue reconstruction using flaps in managing mangled injuries is occasionally insufficient due to large defects and low flap viability. Conversely, delaying the closure of the defect can elevate the risk of infection. Adjuvant therapy becomes essential in the management of mangled injuries. We aim to present the use of low-cost vacuum-assisted closure (VAC) as an adjuvant therapy for mangled injuries. We reported the case of a 20-year-old man who sustained a mangled injury to his left forearm in a traffic accident 4 hours before admission. The mangled extremity severity score was 9; however, the patient declined amputation. Although the initial reconstruction was done, the flap could only cover vital structures. VAC was utilized to address the uncovered portion of the defect, to promote optimal granulation and prevent infection. The reconstruction proceeded with a skin graft and wrist arthrodesis. At 1-year follow-up, viable tissue was obtained but contracture occurred at the metacarpophalangeal and proximal interphalangeal joints. We intend to perform functional reconstruction at a later stage. Although the benefits of VAC in wound management are well established, reports regarding its advantages in mangled injury management remain relatively scarce. The high cost of VAC is a limiting factor, particularly in developing countries. This prompts the need for an affordable VAC innovation with comparable efficiency to the commercial model. Reverse Aqua Pump VAC, our innovative low-cost VAC, shows satisfactory outcomes in managing patients with mangled injuries with mangled extremity severity score indicating amputation.

Efficacy of damage control orthopedics strategy in the management of lower limb trauma

BackgroundLittle is known about the efficacy of damage control (DC) surgery in the management of lower limb trauma. Here we compared the clinical parameters and complication rates of such patients received either DC or emergency comprehensive (EC) surgery treatment. MethodsThis study is a retrospective study on patients with lower limb trauma that received surgical treatment. Data of 120 patients were divided into DC and EC surgery groups. Clinical parameters obtained at hospital admission and complications during follow-up were analyzed. Injury Severity Score (ISS), Gustilo classification and Mangled Extremity Severity Score (MESS) were used to assess trauma severity, open fractures and viability of injured limb, respectively. ResultsAge, sex, ISS, fracture type, injury site, MESS, operation time, blood loss, pulmonary and cranial injuries were compared. We found that patients in the DC group had more severe injury as reflected by the higher injury severity score (ISS) (28.1 ± 10.9 vs 21.3 ± 7.4, P < 0.001). ISS was also identified as a significant influencer for the treatment selection (P < 0.001). In addition, patients treated with DC surgery demonstrated less complications (7 cases vs 27 cases), which was supported by the propensity score logistic regression analysis (Odd ratio 4.667). ConclusionsDC surgery is more often selected to treat patients with more severe lower limb injuries, which leads to lower complication rates.

Salvaging mangled upper limbs with early soft tissue cover with flaps- A case series

Mutilating upper limb injuries present complex challenges to both patients and surgeons, necessitating prompt and effective management strategies to achieve favorable outcomes. This retrospective study examines the cases of five consecutive patients with mangled upper limbs resulting from blunt trauma, evaluating demographics, injury mechanisms, injury patterns, and 60-day limb salvage outcomes. Among 2128 admissions between January and December 2022, five patients were identified with mangled upper limbs and open fractures, with an average age of 40.2 years and a notable male predominance (80%). The dominant hand was affected in 60% of cases, primarily due to blunt high-velocity road traffic accidents. The mean Mangled Extremity Severity Score (MESS) was 7.2, and the Ganga Hospital Open Injury Score averaged 16, indicating substantial injury severity without limb ischemia or compartment syndrome. All patients underwent definitive surgery within 48 hours, with various soft tissue reconstruction techniques employed, including free flaps, pedicle flaps, and local muscle mobilization, along with nerve grafting procedures. At the 60-day follow-up, successful limb salvage was achieved in all cases, with no instances of surgical site infection and excellent acceptance of skin grafted areas exceeding 95%. The findings underscore the importance of timely surgical intervention and comprehensive soft tissue coverage in achieving successful limb salvage outcomes in patients with mutilating upper limb injuries, emphasizing the critical role of early intervention and multidisciplinary collaboration.

Emergency vascular repairs in trauma: Predictors of poor prognosis and a novel scoring system.

Vascular injuries comprise 1% to 4% of all trauma patients, and there are no widely used risk-stratification tools. We sought to establish predictors of revascularization failures and compare outcomes of trauma and vascular surgeons. We performed a single-institution, case-control study of consecutive patients with traumatic arterial injuries who underwent open repair between 2016 and 2021. Multivariable logistic regression was used to investigate covariates impacting the primary composite outcome of repair failure/revision, amputation, or in-hospital mortality. Among 165 patients, the median age was 34 years, 149 (90%) were male, and 99 (60%) suffered penetrating injury. Popliteal (46%) and superficial femoral (44%) arterial injuries were most common. Interposition graft/bypass was the most frequent repair (n = 107 [65%]). Revascularization failure was observed in 24 patients (15%). Compared with trauma surgeons, vascular surgeons more frequently repaired blunt injuries (66% vs. 20%, p < 0.001), anterior tibial (18% vs. 5%, p = 0.012), or tibioperoneal injuries (28% vs. 4%, p < 0.001), with a below-knee bypass (38% vs. 20%, p = 0.019). Revascularization failure occurred in 10% (9 of 93) of repairs by trauma surgeons and 21% (13 of 61) of repairs by vascular surgeons. Mangled Extremity Severity Score >8 (odds ratio, 15.6; 95% confidence interval, 4.4-55.9; p < 0.001) and concomitant laparotomy or orthopedic procedure (odds ratio, 6.7; 95% confidence interval, 1.6-28.6; p = 0.010) were independently associated with revascularization failure. A novel composite scoring system (UT Houston Score) was developed by combining Mangled Extremity Severity Score, concomitant procedure, mechanism of injury, and injury location. This score demonstrated a sensitivity of 100% with a score of 0 and a specificity of 95% with a score of >3. After traumatic arterial injury, trauma surgeons repaired less-complex injuries but with fewer revascularization failures than vascular surgeons. The UT Houston Score may be used to risk stratify patients to determine who may benefit from vascular surgery consultation. Therapeutic/Care Management; Level III.

The role of Mangled Extremity Severity Score in amputation triage in a transport health facility with catastrophic earthquake admissions

BackgroundThe purpose of this study is to assess the diagnostic utility of the Mangled Extremity Severity Score (MESS) in the prediction of amputation after a major earthquake, and its utility in disaster triage. MethodsStudy results were presented from a tertiary hospital in Diyarbakır, which was affected by the earthquake but served as a transport hub for other cities in the region affected by the earthquake. MESS was calculated and its diagnostic value is analyzed in predicting amputations. MESS scores were divided into low risk, intermediate risk, and high risk groups by the researchers based on their diagnostic value analysis. Results79 patients were included in the study. Based on the outcome of amputation or salvage, patients were divided into two groups. 24.1% (n = 19) of the patients had amputations. Both gender and mean age did not differ statistically significantly between the groups (p > 0.05). Compared with the salvage group, the amputation group had a significantly longer prehospital stay and higher rate of vascular injury and higher median MESS (p = 0.007, p < 0.001, p < 0.001; respectively). Based on MESS scores, amputation outcomes were predicted with an accuracy of 0.889 (95% CI 0.798–0.949). Those with a MESS score below 9 were considered low risk (sensitivity = 100%) whereas those with a MESS score above 12 were considered high risk (specificity = 98.33%). ConclusionIn transport centers, MESS may be useful for surgical triage of earthquake-induced limb crush injuries.

Hyperbaric oxygen therapy does not change the amputation level in patients with fasciotomy after an earthquake: Our single-center experience after 2023 Kahramanmaras earthquake.

This study aims to evaluate the effect of hyperbaric oxygen therapy (HBOT) on the amputation level in patients undergoing fasciotomy with a Mangled Extremity Severity Score (MESS) score of ≥7 after 2023 Kahramanmaras earthquake. Between February 6th, 2023 and March 10th, 2023, a total of 23 patients (14 males, 9 females; mean age: 36.8±13.2 years; range, 17 to 64 years) who needed amputation with a MESS score of ≥7 and refused amputation were included in the study. All fasciotomies were performed in an external center, and five of them was incomplete. First, incomplete fasciotomies were completed with debridement due to deep muscle necrosis. Daily two HBOT sessions were performed for the first three days. In the following days, daily one HBOT session was performed. The HBOT was terminated for the patients who were decided by the council that they did not benefit from HBOT treatment. Six (26.08%) of the patients had a bone fracture (n=2 forearm, n=1 femur, n=2 tibia, and n=1 ankle fracture). The mean number of HBOT session was 13.24±5.4 (range, 7 to 30) and the mean duration of HBOT was 26.5±10.8 (range, 14 to 60) h. The mean MESS score was 9.96±1.36 (range, 7 to 12). All of the patients were trapped under the rubble with a mean time of 12.3±5.4 (range, 6 to 23) h. All fasciotomies were performed within the first 30 h. Twenty-two of the patients were amputated at the level previously determined by the experienced trauma surgeons. The amputation level changed in only one patient. After 38 h of HBOT, transradial amputation was performed to the patient in whom transhumeral amputation level was determined previously. None of the patients had any adverse event related to HBOT. Our study results suggest that the MESS is a useful scoring system for amputation decision after a high-energy trauma, such as an earthquake, with a high accuracy rate. The outcomes of HBOT are not satisfactory for high-energy traumas, such as earthquakes, in those requiring fasciotomy having more muscle necrosis and a MESS score of ≥7.

Evaluation of musculoskeletal injuries after the 2023 Kahramanmaras earthquake: A local hospital experience.

The aim of this study was to evaluate musculoskeletal injuries, clinical follow-ups and treatments of trauma patients admitted to our hospital after the 2023 Kahramanmaras earthquake. Between February 6th, 2023 and February 16th, 2023, a total of 957 trauma patients (452 males, 505 females; mean age: 36.2±19.9 years; range, 0 to 97 years) who were affected by the earthquake were retrospectively analyzed. Age, sex, presence of orthopedic consultation, diagnosis of open/closed fracture, diagnosis of dislocation, presence and classification of soft tissue injury, additional system injury, preoperative and postoperative neurovascular examination status, presence of compartment syndrome, conservative/surgical applications, operation side, fasciotomy surgery and level, amputation surgery and level, length of stay in the hospital and intensive care unit (ICU), the Mangled Extremity Severity Score (MESS) score were collected. A total of 811 of the survivors were Turkish and 146 were Syrians. Of 957 earthquake victims, 40% had soft tissue injuries, 19% had closed fractures, 8.9% had other system injuries, 7.7% had crush injuries, 4.1% had nerve injuries, 2.1% had compartment syndrome, 2.1% had vascular injury, 1.8% had dislocation, and 1.7% had open fracture. Surgical or conservative treatments were applied to 574 patients with musculoskeletal injuries. Conservative treatment was applied to 322 of 574 patients and surgical procedure was applied to 252 patients. The highest patient density is experienced within the first 24 h after a devastating earthquake. The most common injuries due to high-energy trauma are isolated soft tissue injuries and fractures. The definition of the demographic characteristics and clinical outcomes of earthquake patients is critical to the development of preparedness, response, and recovery policies for future disasters..

Revisiting the Mangled Extremity Severity Score (MESS) in Popliteal Artery Injury: A Single-Centre Experience in Vietnam.

Popliteal artery injury is a severe condition that can lead to limb loss. Early intervention is essential to achieve optimal outcomes, including limb salvage. The Mangled Extremity Severity Score (MESS) is a scoring system used to predict amputation rates for mangled limb injuries. The effectiveness of the MESS in predicting amputationin patients with traumaticpopliteal artery injury is unclear, particularly in settings with a high prevalence of motorcycle accidents. This retrospective study was conducted at a single center in Vietnam between January 2018 and June 2020. The study included 120 patients who underwent surgical treatment for popliteal artery injury. Data were collected from electronic medical records, radiology reports, and operative notes. Logistic regression model and the area under the curve (AUC) were used to evaluate the predictive value of the MESS. Patients with a MESS score of ≥8 had a higher rate of amputation compared to those with a MESS score of <8. However, the predictive value of the MESS was limited, with an AUC of 0.68. Higher skeletal/soft tissue injury score, limb ischemia score, and shock score were associated with a higher risk of amputation. The age score of the MESS was unexpectedly higher in the limb salvage group. The MESS score can be useful in predicting amputation rates in patients with popliteal artery injury, but its predictive value is limited. A team approach involving experienced surgeons is recommended for decision-making regarding amputation.

The Relevance of Mangled Extremity Severity Score to Predict Amputation: A Systematic Review

BACKGROUND: Amputation is one of the most common surgical procedures in the world. One of the criteria for assessing amputation is the mangled extremity severity score (MESS). The MESS criterion has been used for many years, but the accuracy remains unknown. The aim of this study is to know the accuracy of MESS. METHOD: Keywords of “relevance,” “mangled extremity score,” and “amputation,” and its combination were entered into the PubMed database. Four evaluators reviewed articles from the past 5-year publication date with the English language to select relevant articles. RESULTS: The outcomes of this systematic review are the sensitivity and specificity of several scoring tools to predict amputation and recommendations for MESS use. The author identified 26 relevant articles with MESS to predict amputation, and most of them recommend using MESS. The sensitivity and specificity of MESS were variable from 63–73% to 70–76%. CONCLUSION: The MESS performs better in the amputation prediction of the lower extremity arterial injury. Other scoring recommendations are LogisticReg + Nearmiss, ISS, BN, and GHOIS.

Mangled Extremity Severity Score in the Assessment of Extremity Injuries - Is it Reliable?

The mangled extremity severity score (MESS) was established 28years ago to decide performing an amputation in cases of limb trauma. It assigns points for 4 aspects of the injury: the extent of soft tissue and skeletal injury, limb ischemia and ischemic duration, shock, and age. A score of 7 or higher indicates that primary amputation is required. Thirty-one patients with MESS scores of 7 to 8 underwent limb salvage surgeries, with 13 limbs being saved and 18 limbs being amputated. Upper extremities trauma had a salvage rate of 62.5%, whereas lower extremity trauma had a salvage rate of 20%. MESS is not a sensitive predictor of amputation in upper limb trauma, but it is useful in lower limb injuries.

Limb Salvage in a Mangled Foot Using Combined External and Internal Fixation

Abstract Historically, mangled extremities were generally treated with a primary amputation. Advancements in surgical repair and reconstruction have increased the possibility of salvage in the limbs damaged by high-energy trauma, with a reasonably functional outcome. The Mangled Extremity Severity Score is a useful guide for evaluating and managing a crushed limb. However, most literature does not support the practicality of any particular scoring system to discriminate between the limbs requiring amputation and those likely to be salvaged successfully. In young patients, without significant comorbidities and borderline injury scores, an earnest attempt at limb salvage should be made. The case report highlights how shared and timely decision-making coupled with the innovative use of the Ilizarov apparatus, in a seemingly distraught situation, led to successful salvage and restoration of function.

MESS Scale for Combat Limb Injury: Amputation or Salvage?

Summary. Combat injury of the limbs is characterized by multilevel open combined tissue damages, the severity of which in some cases makes it impossible the salvage tactics.&#x0D; Objective: based on the analysis of literature, to investigate the possibility of using MESS (the mangled extremity severity score - assessment of the severity of a broken limb) when establishing indications for early amputation of a severely injured limb due to a combat trauma.&#x0D; Materials and Methods. A literature search was conducted on the PubMed database according to the established criteria. Data were taken from the selected sources: the number of amputation/save cases and the weighted average MESS amputation/save value. A weighted average MESS with a 95% confidence interval (CI) and a coefficient of variation were calculated.&#x0D; Results. A total of 189 sources according to the established criteria were identified for the period 1990-2021, in which MESS was applied; 7 sources were selected for analysis. The generalizing value (weighted average) for MESS for amputations was 7.3; 95% CI (6.27-8.33); the coefficient of variation was 4.1. While preserving the limb, the calculations showed a MESS value of 4.9; 95% CI (4.49-5.31); the coefficient of variation was 8.4.&#x0D; Conclusions. The use of the MESS makes it possible to assess the condition of the injured limb; the value of 7 or above is a reliable predictor for amputation.

The Mangled Extremity Severity Score (MESS) does not predict amputation in popliteal artery injury

PurposeVascular injuries in lower extremity trauma, especially with involvement of the popliteal artery, are associated with considerably high rates of limb loss, especially with blunt trauma mechanisms. The aim of this study was to evaluate the risk of amputation in patients with traumatic popliteal artery lesions with special focus on the validity of the Mangled Extremity Severity Score (MESS).MethodsIn this retrospective study, all patients treated for isolated lesions of the popliteal artery following trauma between January 1990 and December 2020 at a high-volume level I trauma center were included. Primary outcome was limb salvage dependent on MESS and the influence of defined parameters on limb salvage was defined as secondary outcome. The extent of trauma was assessed by the MESS.ResultsA total of 50 patients (age 39.2 ± 18.6 years, 76% male) with most blunt injuries (n = 47, 94%) were included. None of the patients died within 30 days and revascularization was attempted in all patients with no primary amputation and the overall limb salvage rate was 88% (44 patients). A MESS ≥ 7 was observed in 28 patients (56%) with significantly higher rates of performed fasciotomies (92.9% vs. 59.1%; p < 0.01) in those patients. MESS did not predict delayed amputation within our patient cohort (MESS 8.4 ± 4.1 in the amputation group vs. 8.1 ± 3.8 in the limb salvage group; p = 0.765).ConclusionRevascularization of limbs with isolated popliteal artery injuries should always be attempted. MESS did not predict delayed amputation in our cohort with fasciotomy being an important measure to increase limb salvage rates.

Early One Stage Functional Reconstruction of a Mangled Upper Extremity.

A crush injury to the upper extremity with a MESS (Mangled Extremity Severity Score) more than or equal to 10 carries a poor salvage prognosis and functional outcome. Usually performing multiple staged surgeries in these patients make the follow up and rehabilitation regimen long and complicated. This means either the patient doesent return or fails to gain any function. In order to overcome this problem we have done a single stage functional reconstruction in a mangled upper extremity. A young female presented with a crush injuiry of the upper limb where a functional reconstruction with an LD (Latissimus Dorsi) flap was done 48 hrs after limb salvage surgery. The flap provided cover to the shoulder and elbow joint and also acted as a motor for elbow flexion. After 6 months following surgery, the patient had regained active motion in her elbow and shoulder joint, and at 1 year she was able to carry out activities of daily living without any external help. Our case demonstrates that the mangled upper extremity can have varied presentations but the surgeon should use every knowledge and technique at their disposal to achieve the maximum chance of autologous functional reconstruction.

Vascular Trauma in the Extremities: Factors Associated with the Outcome and Assessment of Amputation Indexes.

Traumatic vascular injury in the extremities may be associated with a low mortality rate but can lead to limb loss that seriously affects patients' functionality. Multiple scoring systems have been designed to evaluate the prognosis, but none are 100% predictive. The management of traumatic vascular injury remains challenging and depends mostly on the surgeon's experience. We identified the risks associated with limb loss and further investigated the utility of current amputation indexes. We retrospectively reviewed 53 cases of traumatic vascular injury in the extremities at a tertiary referral medical center over the past ten years (January 2011-December 2020). The mangled extremity severity score (MESS), limb salvage index (LSI), and predictive salvage index (PSI) were used to assess the traumatized limbs. The injury characteristics and outcomes were evaluated using regression analysis. The incidence of limb loss was 20.8% (n = 11), and open fractures were the most related factor. Extensive involvement of soft tissue, vascular injury combined with tibia or fibula fractures, initial shock status, and the amount of transfusion were associated with limb loss. Our study identified the risk factors and clinical utility of MESS, PSI, and LSI. While both LSI and PSI had acceptable diagnostic accuracy, amputation should be decided based on a variety of criteria and clinical features. Salvaging any limb that has not become apparently futile seems logical, yet the presence of certain factors may suggest a worse outcome.

Thin and superthin free flaps: An innovative approach to pediatric extremity reconstruction

IntroductionPublished standards for the management of open extremity fractures have improved limb salvage, fracture union, and deep infection rates, but the aesthetic and functional importance of our flap choices has been overlooked. Thin and superthin free flaps exhibit advantages over traditional free flaps in some situations but have seldom been reported in children. The aim of this paper is to present our experience of thin and superthin free flaps in pediatric extremity reconstruction. MethodsChildren (≤13 years) who underwent soft tissue reconstruction using a thin and superthin free flap following major extremity trauma are presented. ResultsFive patients (5 flaps) met the inclusion criteria. The median age was 9 (range 6–13). There were 3 Gustilo IIIB open fractures and 2 multiplanar degloving injuries. The median mangled extremity severity score (MESS) was 4 (range 2–6). The median time from injury to definitive soft tissue closure was 72 h (range 28–120 h). Four anterolateral thigh (ALT) flaps were raised as thin flaps, and 1 superficial circumflex iliac artery perforator (SCIP) was raised as a superthin flap. There was one re-exploration owing to venous congestion, and a second venous anastomosis was performed to enhance flap drainage. The same ALT flap exhibited necrosis at one margin, which was debrided and grafted before discharge. There were no other flap complications. No flap-related secondary surgeries were required. ConclusionThin and superthin free flaps are viable options in pediatric extremity reconstruction. They exhibit excellent aesthetic and functional contouring when a slender fasciocutaneous flap is needed, especially when body habitus renders traditional options unfavorable.

Limb salvage vs amputation in crush injury due to high energy injury: A case report

Limb injury possesses significant problems, both for the treating physician and patient. Numerous problems ranging from disability, limb amputation or even death can occur to the patient. However, the definitive therapy is still debated. A 50 years old man came to the emergency room with a chief complaint of an open wound of his right leg because of a traffic accident. Subsequently, the repair, secondary closure, and skeletal traction were done following the exploration and debridement. During the next follow up, the surrounding tissues seemed to be non-viable. Therefore, the surgeon decided to do an operation with a urologist to perform hip disarticulation and scrotum necrotomy. The patient undergoes repeated debridement in operating theatre and also using negative pressure wound therapy (NPWT). After three months from the first admission, the patient's condition started to deteriorate, and unfortunately, the patient died. There are several scoring systems that can be used to help determine the management of high energy lower extremity injuries. The most used is Mangled Extremity Severity Score (MESS), Limb Salvage Index (LSI) and Predictive Salvage Index (PSI) scores. Hospital type will surely determine the facility and personnel availability. If the facility and personnel are sufficient, limb reconstruction should be attempted first. However, in the end, the family's consent after considering the risk of the surgery will determine the chosen surgery to perform. The surgeon in charge should consider the decision with high vigilance regarding the patient's clinical condition. The decision between limb salvage and amputation should consider the long-term effect which influences the patient's quality of life.

Analysis of Concomitant and Isolated Venous Injury in Military Lower Extremity Trauma

The implications of major venous injury to the lower extremity are not well established. We aimed to determine the significance of concomitant and isolated femoropopliteal venous injury and assess the impact of surgical management strategies on limb outcomes. The Fasciotomy and Vascular Injury Outcomes database was queried for limbs sustaining femoropopliteal arterial, venous, or concomitant injuries in Iraq or Afghanistan between 2004 and 2012. Demographics, injury patterns and severity, interventions, and outcomes were compared between patients sustaining isolated arterial injuries (IAIs) and concomitant arteriovenous injuries (AVIs). In limbs with any venous injury, outcomes were compared between those undergoing venous repair and venous ligation. Three hundred thirty patients (133 IAIs, 135 AVIs, 62 isolated venous injuries [IVIs]) were included. AVI was associated with greater limb injury severity: median extremity Abbreviated Injury Scale (AVI 4 vs. IAI 3, P=0.01), Mangled Extremity Severity Score >7 (25.9% vs. 13.5%, P=0.01), and multilevel vascular injury (6.7% vs. 0.8%, P=0.01) and with greater fasciotomy use (83.0% vs. 69.2%, P=0.01). No differences were present in tourniquet use/time, shunting, or nature of arterial repair. No differences in vascular or limb complications (71.1% vs. 63.9%, P=0.21) or amputation rate (25.9% vs. 18.8%, P=0.16) were present, though the limb deep venous thrombosis rate was 12.6% in AVIs versus 7.5% in IAIs (P=0.17). Limbs with IVI had a 12.9% amputation and a 74.2% complication rate. Repair (n=103) versus ligation (n=94) of venous injuries was not associated with a difference in amputation (18.4% vs. 25.5%, P=0.23) or limb complication rates (71.8% vs. 72.3%, P=0.94). Despite higher extremity injury severity and more frequent fasciotomies, concomitant venous injury was not associated with poorer limb salvage or complications. With nontrivial amputation and complication rates, IVI is indicative of severe limb trauma. Repair of femoropopliteal venous injuries does not appear to influence limb outcomes.

Popliteal Artery Injury After Fracture and/or Dislocation of the Knee: Risk Stratification for Revascularization Outcome.

Managing complex knee trauma involving both vascular and osseous injuries is challenging, yet the available guidelines for efficient popliteal artery injury management after high-velocity blunt knee trauma remain conflicting and inconsistent. In this study, the authors aim to identify the risk factors associated with delayed limb amputation and ischemic muscular sequela postrevascularization. Furthermore, we propose a treatment algorithm to improve the limb salvage rate. Patients who presented with traumatic popliteal artery injury resulting in vessel occlusion or rupture, followed by fracture and/or dislocation of the knee from January 2008 to December 2013, were included for retrospective review. Overall delayed amputation rate was 24% (7/29) and 16% (4/25) after successful revascularization. Mangled Extremity Severity Score is higher in the delayed amputation group than the limb-salvaged group (P = 0.02). Higher-impact force (P = 0.03), ischemic limb on presentation (P = 0.03), prolonged ischemia time (P = 0.04), unstable hemodynamics (P = 0.01), longer operation time (P = 0.04), and prolonged intensive care unit stay (P = 0.03) are risk factors of delayed amputation. Longer ischemia time (P = 0.04) and length of popliteal artery injury (P = 0.02) are associated with ischemic muscular sequela. Mangled Extremity Severity Score is a reliable predictor of limb salvage. An algorithmic approach may improve the outcome of popliteal artery injury after high-velocity blunt knee trauma.

Analysis Of Concomitant And Isolated Venous Injury In Military Lower Extremity Trauma

OBJECTIVES The implications of major venous injury to the lower extremity are not well established. We aimed to determine the significance of concomitant and isolated femoropopliteal venous injury and assess the impact of surgical management strategies on limb outcomes. METHODS The Fasciotomy and Vascular Injury Outcomes Database was queried for limbs sustaining femoropopliteal arterial, venous, or concomitant injuries in Iraq or Afghanistan between 2004-2012. Demographics, injury patterns and severity, interventions, and outcomes were compared between patients sustaining isolated arterial injuries (IAI) and concomitant arteriovenous injuries (AVI). In limbs with any venous injury, outcomes were compared between those undergoing venous (VR) and ligation (VL). RESULTS 330 patients (133 IAI, 135 AVI, 62 isolated venous injuries-IVI) were included. AVI was associated with greater limb injury severity: median extremity Abbreviated Injury Scale (AVI 4 vs. IAI 3, p=0.01), Mangled Extremity Severity Score >7 (25.9% vs. 13.5%, p= 0.01), multi-level vascular injury (6.7% vs. 0.8%, p=0.01) and with greater fasciotomy use (83.0% vs. 69.2%, p=0.01). No differences were present in tourniquet use/time, shunting, or nature of arterial repair. No differences in vascular or limb complications (71.1% vs. 63.9%, p=0.21) or amputation rate (25.9% vs. 18.8%, p=0.16) were present, though limb DVT rate was 12.6% in AVI vs. 7.5% in IAI (p=0.17). Limbs with IVI had a 12.9% amputation and a 74.2% complication rate. Repair (n=103) versus ligation (n=94) of venous injuries was not associated with a difference in amputation (18.4% vs. 25.5%, p=0.23) or limb complication rates (71.8% vs. 72.3%, p=0.94). CONCLUSION Despite higher extremity injury severity and more frequent fasciotomies, concomitant venous injury was not associated with poorer limb salvage or complications. With nontrivial amputation and complication rates, IVI is indicative of severe limb trauma. Repair of femoropopliteal venous injuries does not appear to influence limb outcomes.

Limbs with IVI had a 12.9% amputation and a 74.2% complication rate. Repair (n=103) versus ligation (n=94) of venous injuries was not associated with a difference in amputation (18.4% vs. 25.5%, p=0.23) or limb complication rates (71.8% vs. 72.3%, p=0.94). Despite higher extremity injury severity and more frequent fasciotomies, concomitant venous injury was not associated with poorer limb salvage or complications. With nontrivial amputation and complication rates, IVI is indicative of severe limb trauma. Repair of femoropopliteal venous injuries does not appear to influence limb outcomes.
