RESUMO
BACKGROUND: High-energy casualties such as firearm injuries may result in extensive loss of soft tissue and bone in the lower extremities. Although the primary aim in these types of injuries is the preservation of the extremity, repeated surgical procedures for extremity salvage and subsequent restoration of function could have detrimental effects on the patient both physically and psychologically. The main aim of this study is to evaluate the physical and psychological outcomes of patients who underwent lower extremity amputation in the early period after a firearm injury compared with the results of patients who underwent amputation in the late period. We also evaluated the factors affecting the prognosis in patients undergoing late below-knee amputation (BKA). METHODS: This retrospective study included patients who underwent BKA following a lower extremity injury caused by firearms between March 2016 and March 2022. Patients who underwent emergency BKA at the first center they were taken to immediately after the injury constituted the early amputation (EA) group. Patients who were transferred to our tertiary-level referral center for continuation of treatment after the first intervention at another center and later underwent BKA constituted the late amputation (LA) group. The patients were evaluated regarding age, gender, amputation side, presence of phantom limb pain (PLP), and post-traumatic stress disorder (PTSD). RESULTS: Information was available from hospital records for a total of 35 patients; 16 in the EA group and 19 in the LA group. All patients were male. The mean age at the time of injury was 25.5±5.3 years (range, 20-45 years), and the mean follow-up period was 37±17 months (range, 25-84 months). In the comparison of PLP experienced, the difference between the groups was statistically significant, with PLP experienced by 1 (10%) patient in the EA group and by 9 (90%) in the LA group (p=0.010). PTSD was diagnosed in 3 (23%) patients in the EA group and 10 (77%) patients in the LA group (p=0.039). CONCLUSION: Patients who underwent late BKA were found to be affected by PLP and PTSD at a higher rate. When deciding on extremity-preserving surgery for patients with severe open injuries to the lower extremity, it is crucial to consider the poor outcomes associated with late BKA. Patients should be thoroughly informed about these negative outcomes.

The challenge in treating traumatic hemipelvectomy is the dynamics of the complex and life-threatening consequences of the injury. These include skin and soft tissue defects, osseous, neural and vascular injuries as well as the subsequent hemostatic derangement and organ dysfunction as part of the shock process. The treatment requires rapid and targeted decisions to save the patient's life. In this particular case a 34-year-old farmer was trapped between a wheeled loader and a stationary trailer. Upon arrival at the hospital the patient was in a state of hemorrhagic shock with accompanying acute traumatic coagulopathy and a grade III open pelvic trauma with complete ischemia of the left leg and a bladder injury. After performing emergency surgery and a two-stage approach for pelvic stabilization the patient's condition deteriorated up to multiorgan failure, necessitating left-sided hemipelvectomy as an immediate life-saving salvage procedure. In the further course multiple revision surgeries and plastic reconstructions due to wound infections and the presence of skin and soft tissue damage were required. Due to the rare confrontation with this type of injury in everyday practice and the absence of a universal treatment algorithm, the following case report is intended to contribute to a better understanding of the treatment and to illustrate the coherent interactions of the individual organ systems affected.

INTRODUCTION: Purpose of the study was to answer the question, if there are common fracture or injury characteristics, which help to identify patient at risk for a secondary compartment syndrome. MATERIALS AND METHODS: Between 2003 and 2022 all children and adolescents who were treated for a traumatic compartment syndrome in a lower extremity were retrospectively evaluated. Patient's demographics were recorded, the underlying trauma mechanism identified. Fractures were classified, treatment and complications were analyzed. We differentiated two groups of patients (early onset vs. late onset) and compared trauma mechanism, fracture location, classification and treatment between those two entities. RESULTS: Our collective consisted of 56 children and adolescents with 67 compartment syndromes, with an average age of 14.1 years (5-17). 41 (73.2 %) of the patients were male and 15 (26.8 %) female. Most people in our sample had previously been involved in traffic accidents (64.3 %), with the most common mechanism of injury being "motorbike accident" (34.3 %) and "pedestrian/cyclist accident against car" (26.9 %). There was an accumulation of fractures of the lower leg, in particular tibial shaft fractures (AO 42 and 43A; 49.3 %). In our survey, dislocated fractures and fractures of the foot always led to an early onset of compartment syndrome. The tibial shaft fracture and the surgical treatment with intramedullary nailing showed a significant frequency in the late onset group. CONCLUSIONS: Special attention should be paid to pediatric and adolescent patients with tibial shaft fracture and surgical treatment with intramedullary nailing in order to detect and treat a possible late onset of a compartment syndrome at an early stage.

INTRODUCTION: There are many suitable techniques for the treatment of soft tissue defects of the lower limb. Older subjects often with multiple comorbidities, presenting with a laterally located and complex defect, can be challenging to treat. This cohort are often unsuited to long procedures or multi-stage reconstruction and so one is faced with a paucity of options. In such instances, we use the peroneus brevis (PB) muscle flap as a single stage procedure. METHODS: We performed a retrospective study evaluating the use of PB flaps in lower limb injury. Subjects were collated using a database and multiple variables were assessed including: patient demographics, comorbidities, defect size, peri-operative timings, time in theatre, use of inotropes / blood transfusion, mean hospital stay, patient morbidity / mortality, flap survival. RESULTS: During 2015-2023, 49 patients underwent lower limb reconstruction using PB muscle flaps. 42 cases involved PB and skin graft alone whilst seven were more complex requiring additional local and free tissue techniques. The most common indication (n = 28) was infection after closed fracture fixation, followed by open trauma (n = 21). Median patient age was 59 (20-93 years), and ASA grade 3. Median defect size was 4 × 7 cm (2-18 cm) and time from admission to definitive closure 4 days (0-21 days) with median time in theatre 120 min (45-520 min). 17 patients required inotropes and 13 had blood transfusion. Median length of hospital stay was 12 days (0-58 days), one patient (aged 90) died. 100 % of flaps survived and median Enneking score was 65. Heterotopic ossification was not identified in the post-operative imaging within the first year. DISCUSSION: Our experience highlights the benefits and risks of using the PB flap and advocates it as a reliable, cost-effective, 1-stage technique for reconstructing small lateral defects in the distal third of the lower limb.

BACKGROUND: Carbon-fiber custom dynamic orthoses are used to improve gait and limb function following lower limb trauma in specialty centers. However, the effects of commercially available orthoses on center of pressure progression and patient perception of orthosis smoothness during walking are poorly understood. METHODS: In total, 16 participants with a unilateral lower extremity traumatic injury underwent gait analysis when walking without an orthosis, and while wearing monolithic and modular devices, in a randomized order. Device alignment, stiffness, participant rating of perceived device smoothness, center of pressure velocity, and ankle zero moment crossing were assessed. FINDINGS: The modular device was approximately twice as stiff as the monolithic device. Alignment, smoothness ratings, peak magnitude of center of pressure velocity, and zero moment crossing were not different between study devices. The time to peak center of pressure velocity occurred significantly later for the modular device compared to the monolithic and no orthosis conditions, with large effect sizes observed. INTERPRETATION: Commercially available orthoses commonly used to treat limb trauma affect the timing of center of pressure progression relative to walking without an orthosis. Despite multiple design differences, monolithic and modular orthoses included in this study did not differ with respect to other measures of center of pressure progression. Perceived smoothness ratings were approximately 40% greater with the study orthoses as compared to previous studies in specialty centers, which may be due to a more gradual center of pressure progression, as indicted by lower peak magnitude of center of pressure velocity with both study orthoses.

ABSTRACT: Reconstruction of traumatic defects of the lower third of the leg poses a challenge due to limited locoregional options. Failed coverage can be associated with prolonged hospital stay, infection, loss of function, and unplanned return to surgery. Over the last few decades, free tissue transfer has dominated reconstructive algorithms for such defects; however, locoregional flaps may provide equally effective coverage in select patients. In the wake of the CODID-19 pandemic, locoregional flaps gained more consideration due to limited resources. We present a literature review and discussion of locoregional flaps, with emphasis on the quality and efficacy of these reconstructive modalities compared with free tissue transfer and surgical indications.Soleus flaps, reverse sural flaps, and cutaneous perforator-based flaps are workhorses for small to medium size defects of the distal third of the leg, even in the setting of concomitant orthopedic trauma and exposed vital structures. It is important to consider such alternatives an integral part of the reconstructive algorithm as they can provide durable coverage with a favorable complication profile with less resource utilization. Appropriate patient selection requires consideration of the character of the defect, smoking status, preexisting vascular disease, and the zone of injury.

Assessment of player's postural control following a lower limb injury is of interest to sports medicine practitioners due to its fundamental role in daily tasks and sporting activities. The aim was to longitudinally monitor professional rugby union players' postural control during each phase of the rehabilitation program (acute, middle, and late) following a lower limb injury. Seven male rugby union players (height 1.80 [0.02] m; mass 100.3 [11.4] kg; age 24 [4] y) sustained a time loss, noncontact lower limb injury. Static postural control was assessed via sway path (in meters), and dynamic postural control was assessed via vertical postural stability index. Group differences (P < .05) were reported across the acute, middle, and late phase. Smaller magnitudes of sway path were observed for eyes-open sway path, and for the middle and late phase smaller magnitudes of vertical postural stability index (P < .05) at the end session compared with first session. Whereas larger magnitudes of vertical postural stability index were found between baseline and the last session (P < .05). Large interindividual and intraindividual variation was apparent across the 3 phases of rehabilitation. Postural control improvements were identified during rehabilitation. However, postural control did not return to baseline, with altered kinetics throughout each rehabilitation phase.

BACKGROUND: Lower-extremity injuries can result in severe impairment and substantial years lived with a disability. Persistent pain and psychological distress are risk factors for poor long-term outcomes and negatively influence the recovery process following a traumatic injury. Cognitive-behavioral therapy (CBT) interventions have the potential to address these risk factors and subsequently improve outcomes. This study aimed to evaluate the effect of a telephone-delivered cognitive-behavioral-based physical therapy (CBPT) program on physical function, pain, and general health at 12 months after hospital discharge following lower-extremity trauma. The CBPT program was hypothesized to improve outcomes compared with an education program. METHODS: A multicenter, randomized controlled trial was conducted involving 325 patients who were 18 to 60 years of age and had at least 1 acute orthopaedic injury to the lower extremity or to the pelvis or acetabulum requiring operative fixation. Patients were recruited from 6 Level-I trauma centers and were screened and randomized to the CBPT program or the education program early after hospital discharge. The primary outcome was the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) scale. The secondary outcomes were objective physical function tests (4-square step test, timed stair ascent test, sit-to-stand test, and self-selected walking speed test), PROMIS Pain Intensity and Pain Interference, and the Veterans RAND 12-Item Health Survey. Treatment effects were calculated using targeted maximum likelihood estimation, a robust analytical approach appropriate for causal inference with longitudinal data. RESULTS: The mean treatment effect on the 12-month baseline change in PROMIS PF was 0.94 (95% confidence interval, -0.68 to 2.64; p = 0.23). There were also no observed differences in secondary outcomes between the intervention group and the control group. CONCLUSIONS: The telephone-delivered CBPT did not appear to yield any benefits for patients with traumatic lower-extremity injuries in terms of physical function, pain intensity, pain interference, or general health. Improvements were observed in both groups, which questions the utility of telephone-delivered cognitive-behavioral strategies over educational programs. LEVEL OF EVIDENCE: Therapeutic Level I .

BACKGROUND: Routine evaluation with CTA for patients with isolated lower extremity penetrating trauma and normal ankle-brachial-indices (ABI) remains controversial. While prior literature has found normal ABI's (≥0.9) and a normal clinical examination to be adequate for safe discharge, there remains concern for missed injuries which could lead to delayed surgical intervention and unnecessary morbidity. Our hypothesis was that routine CTA after isolated lower extremity penetrating trauma with normal ABIs and clinical examination is not cost-effective. METHODS: We performed a decision-analytic model to evaluate the cost-effectiveness of obtaining a CTA routinely compared to clinical observation and ABI evaluation in hemodynamically normal patients with isolated penetrating lower extremity trauma. Our base case was a patient that sustained penetrating lower extremity trauma with normal ABIs that received a CTA in the trauma bay. Costs, probability, and Quality-Adjusted Life Years (QALYs) were generated from published literature. RESULTS: Clinical evaluation only (no CTA) was cost-effective with a cost of $2056.13 and 0.98 QALYs gained compared to routine CTA which had increased costs of $7449.91 and lower QALYs 0.92. Using one-way sensitivity analysis, routine CTA does not become the cost-effective strategy until the cost of a missed injury reaches $210,075.83. CONCLUSIONS: Patients with isolated, penetrating lower extremity trauma with normal ABIs and clinical examination do not warrant routine CTA as there is no benefit with increased costs.

BACKGROUND: Of all body regions, lower extremity wounds have been and remain the greatest challenge. Free flaps have been accepted as a reasonable option to solve this dilemma, but they require the complexity of microsurgery. This study aimed to compare the postoperative and clinical outcomes of propeller flap and fasciocutaneous free flap in the reconstruction of complex lower limb defects. MATERIALS AND METHODS: This randomized controlled trial was conducted from July 2021 to June 2023. Selected patients were randomized into two groups: the propeller flap group and fasciocutaneous free flap group. Demographic data, preoperative parameters, and postoperative parameter, including esthetic analysis, scar assessment, neurosensory analysis, psychosocial analysis, and lower extremity function, were estimated and statistically significant compared between the two study groups. RESULTS: Road traffic accident (73.3%) was the most common etiology for lower limb defects in both groups. The foot and lower third of the leg were the most common site of defect, constituting 79.99%. The duration of surgery was significantly shorter in propeller flap as compared to fasciocutaneous free flaps. Flap size was smaller, with better neurosensory improvements in propeller flap group. Esthetic analysis, scar assessment, psychosocial analysis, and lower extremity functional analysis yielded similar results in both study groups. CONCLUSION: Propeller flap has better outcomes compared to free flap in terms of smaller size of flap, shorter duration of surgery, and reduced length of hospital stay. Comparable results were obtained with respect to esthetic score, scar assessment score, psychosocial analysis, and neurosensory recovery and lower extremity functional score.

OBJECTIVES: This study aimed to present our experiences with cross-leg flap surgery, which demonstrates successful outcomes in lower limb soft tissue defects without the necessity of microsurgical intervention. PATIENTS AND METHODS: The retrospective study included 26 patients (18 males, 8 females; mean age: 35.6±12.2 years; range, 18 to 65 years) between January 2015 and September 2019. A fasciocutaneous cross-leg flap was applied to the recipient extremity, and the extremities were immobilized by a tubular external fixator. Flap divisions were performed on the 21st postoperative day. At least two years of clinical outcomes were presented. RESULTS: Twenty-five flaps survived and recovered completely without any complication at the donor site, flaps, or the recipient area. In one diabetic patient, partial flap loss was encountered, which granulated with secondary healing. All patients demonstrated stable wound coverage, with none demanding additional soft tissue surgeries. All patients resumed normal ambulation and physical activity without any residual joint stiffness. CONCLUSION: Cross-leg flap method is an effective and respectable option for extremity salvage as a good alternative to free flaps for the management of traumatic complex lower limb defects. This method is simple, provides abundant blood supply to the wound, and does not require microsurgical experience or a good working recipient artery.

ABSTRACT: Recognizing when an injury is concerning for abuse is of utmost importance, as failure to do so places the child at a significant risk for further inflicted injury. Misinterpreting accidental injury as abuse can also have dire consequences for a child and their caregivers. The provider must be aware of characteristics of cutaneous injuries, including burns, that are concerning for abuse. Understanding these characteristics and putting them into clinical practice is necessary to protect children from additional abuse and protect families from wrongful accusations. This case report evaluates a 12-month-old boy who presented to a pediatric emergency room with a patterned, full-thickness burn to the leg. After evaluation, we summarized the additional medical evaluation needed, including a focused history and physical examination, and recommended appropriate diagnostic testing needed to evaluate a child of this age for possible child maltreatment.

INTRODUCTION: Although there are studies comparing methods for leg fasciotomy in compartment syndrome after fractures, choice of single or double fasciotomies in disasters was not investigated. The aim of this study was to compare the efficacy of single and double incision leg fasciotomy in the setting of disaster. METHODS: Patients that have undergone fasciotomy after 2023 Kahramanmaras earthquakes were retrospectively analyzed. The cases were separated into two groups as single incision and double incision according to the method of the first fasciotomy. The number of debridements after each fasciotomy, muscle group excisions, completion time of treatment, presence of amputation, the method of closure (primary closure or graft/flap) and positive results of wound cultures were analyzed and compared between two groups. RESULTS: 62 legs of 52 patients (22 females, 30 males, age 36.9 ± 11.2 years) with compartment syndrome that have undergone fasciotomy after 2023 Kahramanmaras earthquakes were included in the study. Single-incision group included 27 legs and double incision group included 35 legs. Amputation was needed in 15 patients (%24.2), six in single incision group and nine in double incision group. (p = 0.75). Compartment excision (eight patients in single incision, nine patients in double incision groups, p = 0.81), number of debridements (median 4 in both groups, p = 0.55), wound closure time (median 17 days in single incision, 22 days in double incision groups, p = 0.52), graft or flap requirement (11 patients in single incision, 16 patients in double incision groups, p = 0.53), positive culture results (15 patients in single incision, 16 patients in double incision groups, p = 0.44) were not different statistically between two groups. CONCLUSION: Single and double incision fasciotomy methods are equally effective and safe in treatment of compartment syndrome of the leg in disaster situations. To our knowledge, this is the first study comparing outcomes of single and double incision fasciotomy in disaster settings.

PURPOSE: The primary aim of this study was to investigate the risk factors associated with poor outcomes following acute compartment syndrome (ACS) of lower leg. The secondary objective was to determine if delayed fasciotomy is linked to poor outcomes. METHODS: In this retrospective case control study approved by the institutional review board, we identified 103 patients with ACS of the lower leg. Poor outcome was defined as a composite variable that included limb amputation, neurological deficit and contracture. Among these, 44 patients exhibited poor outcome while 59 patients demonstrated a good outcome. Patient-related factors, laboratory values, and treatment-related factors were analyzed using electronic medical records. Univariate statistical and logistic regression analyses were conducted to determine significance. RESULTS: Bivariate analyses showed that the mechanism of injury (P = 0.021), open injury (P = 0.001), arterial injury (P<0.001), hemoglobin levels (HB) (P < 0.001), white blood cell count (WBC) (P = 0.008), albumin levels (ALB) (P<0.001), creatine kinase levels (CK) at presentation (P = 0.015), CK at peak (P<0.001), creatine kinase levels (Ca) (P = 0.004), dehydrating agent (P = 0.036), and debridement (P = 0.005) were found to be associated with the risk of poor outcomes. Logistic regression analyses revealed that arterial injury [ P< 0.001, OR = 66.172, 95% CI (10.536, 415.611)] was an independent risk factor for poor outcomes. However, HB [P = 0.005, OR = 0.934, 95% CI (0.891, 0.979)] was a protective factor against poor outcomes. Receiver operating characteristic (ROC) curve analysis showed that the cut-off values of HB to prevent poor outcome following ACS was 102.45 g/L. CONCLUSIONS: ACS of the lower leg is a serious complication often associated with a poor prognosis. Patients with arterial injury or lower HB have a significantly increased risk of having poor outcomes. Poor outcomes were not found to be associated with the timing of fasciotomy in this study.

BACKGROUND: The purpose of this study was to compare 18-month clinical and patient-reported outcomes between patients with severe lower-limb injuries treated with a transtibial amputation or a hind- or midfoot amputation. Despite the theoretical benefits of hind- and midfoot-level amputation, we hypothesized that patients with transtibial amputations would report better function and have fewer complications. METHODS: The study included patients 18 to 60 years of age who were treated with a transtibial amputation (n = 77) or a distal amputation (n = 17) and who were enrolled in the prospective, multicenter Outcomes Following Severe Distal Tibial, Ankle, and/or Foot Trauma (OUTLET) study. The primary outcome was the difference in Short Musculoskeletal Function Assessment (SMFA) scores, and secondary outcomes included pain, complications, amputation revision, and amputation healing. RESULTS: There were no significant differences between patients with distal versus transtibial amputation in any of the domains of the SMFA: dysfunction index [distal versus transtibial], 31.2 versus 22.3 (p = 0.13); daily activities, 37.3 versus 26.0 (p = 0.17); emotional status, 41.4 versus 29.3 (p = 0.07); mobility, 36.5 versus 27.8 (p = 0.20); and bother index, 34.4 versus 23.6 (p = 0.14). Rates of complications requiring revision were higher for distal amputations but not significantly so (23.5% versus 13.3%; p = 0.28). One distal and no transtibial amputees required revision to a higher level (p = 0.18). A higher proportion of patients with distal compared with transtibial amputation required local surgical revision (17.7% versus 13.3%; p = 0.69). There was no significant difference between the distal and transtibial groups in scores on the Brief Pain Index at 18 months post-injury. CONCLUSIONS: Surgical complication rates did not differ significantly between patients who underwent transtibial versus hind- or midfoot amputation for severe lower-extremity injury. The average SMFA scores were higher (worse), although not significantly different, for patients undergoing distal compared with transtibial amputation, and more patients with distal amputation had a complication requiring surgical revision. Of note, more patients with distal amputation required closure with an atypical flap, which likely contributed to less favorable outcomes. LEVEL OF EVIDENCE: Therapeutic Level III .

PURPOSE: To compare dermal regenerative template (DRT), with and without split-thickness skin-grafting (STSG), and urinary bladder matrix (UBM) for coverage of lower extremity wounds. METHODS: A retrospective review of 56 lower extremity wounds treated with either DRT and STSG (DRT-S) (n = 18), DRT only (n = 17), or UBM only (n = 21). Patient characteristics, comorbidities, American Society of Anesthesiology (ASA) classification, injury characteristics, wound characteristics, use of negative pressure wound therapy, surgical details, postoperative care, and failure of primary wound coverage procedure were documented. RESULTS: The DRT group, compared to the DRT-S group, was older [median difference (MD) 17.4 years, 95% confidence interval (CI) 9.1-25.7; p = 0.0008], more diabetic (proportional difference (PD) 54.2%, CI 21.2-76.1%; p = 0.002), had smaller wounds (MD - 91.0 cm2, CI - 125.0 to - 38.0; p = 0.0008), more infected wounds (PD 49.0%, CI 16.1-71.7%; p = 0.009), a shorter length of stay after coverage (MD - 5.0 days, CI - 29.0 to - 1.0; p = 0.005), and no difference in primary wound coverage failure (41.2% vs. 55.6%; p = 0.50). The UBM group, compared to the DRT group, was younger (MD - 6.8 years; CI - 13.5 to - 0.1; p = 0.04), had fewer patients with an ASA > 2 (PD - 35.0%, CI - 55.2% to - 7.0%; p = 0.02), diabetes (PD - 49.2%, CI - 72.4% to - 17.6%; p = 0.003), and had no difference in primary wound coverage failure (36.4% vs. 41.2%; p = 1.0). Failure of primary wound coverage was found to only be associated with larger wound surface areas (MD 22.0 cm2, CI 4.0-90.0; p = 0.01). CONCLUSIONS: DRT and UBM coverage had similar rates of primary wound coverage failure for lower extremity wounds. LEVEL OF EVIDENCE: Diagnostic, Level III.
