Lower limb amputation in trauma sequelae: choice of level and techniques
Lo Scalpello - Otodi Educational
The main purpose of amputation is to bring a specific patient, regardless of the initial scenario, to a new normality, characterized by the absence of pain and functional potential of the stump in terms of wearability and power. It is therefore implicit that the strategy is played on the choice of the level, using both analysis of the scenario of the patient and the perspective of the prosthetic project. Hence the delicacy of the choice of the moment and the level of amputation, considering multiple possibilities arising from evolution of surgical techniques, interdigitation of skills between traumatologist and plastic surgeon, translation of some techniques initially used for amputations of the upper limb to amputations of the lower limb, to substantial innovations in limb prostheses.
Current Trauma Reports
Purpose of Review To provide an overview of patient management and surgical technique regarded as best practice in optimising outcome following primary and secondary amputation in trauma patients. This is supported by evidence where available. Recent Findings There is increasing evidence that primary amputation may offer superior outcome to reconstruction in severe open lower limb injuries, particularly segmental trauma involving the foot and tibia. Similarly, patients considering complex reconstructive procedures for failed trauma management should be counselled that reported outcomes are equivalent or better following amputation and are achieved faster and with less complications. Patients should be fully informed of this when making decisions about management, though this needs to be individualised. Various surgical techniques have been associated with improved outcome and these are described herein. Careful peri-operative pain management has been associated with faster rehabilitation, better psychological response and a reduced risk of chronic pain. On discharge, patients should be linked to rehabilitation, prosthetic and clinical psychology services and these should be integrated where possible. Summary A holistic, multidisciplinary approach is recommended in all aspects of care and should be available from the outset. Patients should be optimised medically and functionally, where possible pre-operatively. Psychological assessment and early information sharing are recommended. Where this is not possible due to acuity, these issues should be addressed as soon as possible post-amputation. Particularly where the limb is severely injured, careful planning and joint operating by senior Orthopaedic, Plastic and Vascular surgeons can achieve the best results.
Amputation is one of the oldest surgical procedure and a good amputation results in optimal functional outcome by providing healthy residual limb. Advances in prosthetics has enabled amputee with diverse options and better functionality. There is also decrease in the overall burden of amputation as a result of better treatment of causative disorders and proper limb salvage techniques. Complications, however, pose challenges in regain of necessary functions and include an array of disorders related to the procedure, technique and other factors. An understanding of common and practical complications is helpful in their anticipation and relevant prohibitive measures. Apart from it, a comprehensive study that highlights pattern of amputations and related complications provides database for preventive and management strategy. A total of 69 cases of extremity amputations were included within a defined period of Jan 2011 to June 2016. Relevant demographic data were noted along with other details amputation and complications. An attempt is also made for co-morbidities associated in cases with complications. Males (88.40%) and lower extremity (66.66%) were involved more commonly than females and upper extremity. Below knee was commonest (50.72%) lower and below elbow along with digital amputations were commonest (15.94% each) upper extremity amputations. The significant complication that required increased hospital stay or additional procedures were noted in 34 (49.27%) cases. Delayed wound healing, wound dehiscence, painful neuroma, stiffness, exposed bone and phantom pain were some of major complication noted in the study. A brief notes on patient characteristics has been attributed to the nature of trauma, co-morbidities and substance abuse among the complicated cases. The early recognition of complication and prompt management goes a long way in abetment of agony and discomfort of patient affecting overall outcome.
Revascularization of post-traumatic leg amputation: a case report
Ghana Medical Journal
There are few reports on lower extremity revascularization because of its high risks of general and local complications as well as poor functional prognosis. However, revascularization of the traumatically amputated lower extremity is a technically feasible surgical undertaking if there can be effective collaboration between the orthopaedic surgeon and the vascular surgeon. Successful outcome is usually judged by functional achievements of the patient toward returning to the preinjury level. Appropriate patient selection significantly increases the potential for obtaining a satisfactory outcome. We report the successful revascularization of a near amputation of the right leg of a young man who was knocked down accidentally by a speeding taxi leading to mangled and near amputation of his right leg. He underwent successful revascularization and currently doing well, one year after the surgery. Successful revascularization is possible if indicated in less resource countries especially if there is an experienced team of vascular and orthopaedic surgeons.
Severe complex injuries to the upper extremity: Revascularization and replantation
The Journal of Hand Surgery, 1991
Twenty-nine patients with an incomplete (26) or a complete (3) amputation of the upper extremity proximal to the wrist with revascularization or replantation were reviewed. Limb survival rates were very high (93%) despite the severity of the injuries. All patients regained some useful hand function, with 76% attaining a group I or group II (Chen criteria) functional result. Bone shortening osteotomies are a helpful way to reduce the soft tissue defect size. In contrast to earlier studies, clear correlations between the level of injury, degree of nerve lesion, bone pathology, and the number of major nerves involved, and the functional outcome achieved were not found. There was a weak correlation between the type of wound and the functional recovery ultimately obtained. (J HAND SURC 1991;16A:574-84.)
Trends in the Management of Traumatic Upper Extremity Amputations
The Journal of Hand Surgery, 2020
Purpose Treatment for upper extremity amputations includes revision amputation or attempted replantation. The rate of digital replantation has been declining in the United States. Prior studies discovered the presence of socioeconomic disparities associated with these injuries. The goals of this study were to investigate yearly trends of traumatic upper extremity amputations and evaluate the presence of disparities with access to care in these injuries. Methods The 2008 to 2014 New York Statewide Planning and Research Cooperative System (SPARCS) inpatient and outpatient databases were utilized to identify patients who had traumatic upper extremity amputations. We queried the database for patient characteristics, resource utilization characteristics, insurance status, major in-hospital complications, and mortality. Patients at low-, medium-, and high-volume institutions were compared. We performed multivariable logistic regressions for the binary variable replantation (yes/no) controlling for age, sex, race, insurance status, amputation level, admission hour, and comorbidities. Results A total of 2,492 patients met our inclusion criteria: 92.1% sustained digital amputations and 7.9% sustained arm amputations. The annual rate of inpatient finger amputations decreased significantly (1.9 per 100,000 people in 2008 vs 1.4 per 100,000 people in 2014) during the study period while that of outpatient finger amputations increased significantly (12.0 per 100,000 people in 2008 vs 15.5 per 100,000 people in 2014). Multivariable analysis demonstrated incrementally lower odds for replantation with increasing age and increased odds for replantation in patients with private insurance (odds ratio, 1.64; 95% confidence interval, 1.08e2.50). The number of replantation surgeries at medium-volume institutions decreased by 45% while remaining steady in low-and high-volume institutions. Conclusions Our findings corroborate the findings of other studies that underscore the existence of disparities with respect to insurance status in these injuries. Replantations occur more frequently at high-volume hospitals and are more common in younger patients with private insurance. This finding suggests that patients with traumatic amputations may benefit from treatment at high-volume institutions. Further research to help improve access to such institutions is warranted.
Actualities in big segments replantation surgery
Replantation of an amputation is no longer a difficult technical problem. Indeed, the experience gathered over the last few decades, right from the first concepts posed by the pioneers up to the present era and the improved technical aids, all go to suggest that the majority of amputated segments may now be reconstructed. However, what we really want from a replant is not just survival but function. Indications for replantations must follow careful and objective patient selection together with the evaluation of type and site of lesion and possible complications. Furthermore, the important role of emergency organization in this type of surgery is to be emphasized. Nowadays, clean cut injuries are rarer and are being substituted by high energy trauma which may produce extensive tissue lesions that increase complications and lead to poor functional results. Consequently, some authors were induced to describe evaluation systems for decision making which still present problems which are in part due to the large number of parameters to be taken into consideration as well as to the complex functionality of the upper limb. This led us to evaluate our case series of 52 major replantations of the upper limb over the last 10 years and to compare it with other published series. The best form of reconstruction following total amputation of a major limb segment is still its replantation. The highly significant increase in the quality of life is able to justify the higher social costs and the number of operations required.
Traumatic limb amputations at a level I trauma center
European Journal of Trauma and Emergency Surgery, 2011
Introduction The purpose of this study was to analyze the epidemiology and outcomes after traumatic amputation of the upper (UEA) and lower (LEA) extremities. Methods The Los Angeles County ? University of Southern California Medical Center trauma registry was utilized to identify all patients sustaining traumatic amputation during the years 1996-2007. The demographics, mechanism of injury, clinical characteristics, associated injuries, surgical procedures, complications, and outcomes were obtained for these patients. Results During the 12-year study period, 130 patients suffered limb amputation, accounting for 0.25% of all trauma admissions. Thirteen patients (10%) were excluded because they were transferred from another facility after amputation or died in the emergency department. Of the remaining 117 patients, mean age was 38.1 ± 16.4 years and 77.8% were male. The predominant mechanism of injury was automobile versus pedestrian (27.4%), followed by work-related accidents (23.9%). Patients struck by vehicles were more likely to suffer LEA (93.8% versus 6.2%, p \ 0.001), while patients with work-related accidents were more likely to sustain UEA (81.5% versus 18.5%, p \ 0.001). Only nine patients underwent reattachment, all of which were for UEA and unsuccessful. Overall, 24.8% developed a complication during their hospital course, 55.2% of which were extremity related. Overall mortality was 3.4%, primarily attributed to associated severe traumatic brain injuries and thoracic injuries. Patients with LEA had longer hospital and intensive care unit (ICU) length of stay; however, after adjusting for confounders, this difference did not reach statistical significance (adjusted mean difference: 2.1 and 1.2 days, p = 0.69 and 0.79, respectively). A higher percentage of patients with LEA required discharge to a skilled nursing facility or rehabilitation center when compared with patients with UEA (29.6% versus 4.8%, p = 0.001). Conclusions Traumatic limb amputation is a rare consequence of civilian trauma. Amputation is rarely the primary cause of death; however, these devastating injuries are associated with significant intensive care unit and hospital lengths of stay. Although no mortality difference was detected, when compared with patients with upper extremity amputations, patients with lower extremity amputations were more severely injured, required revision extremity surgery more often, had a higher complication rate, and more frequently required discharge to a long-term facility.
Traumatic and trauma-related amputations: Part II: Upper extremity and future directions
The Journal of bone and joint surgery. American volume, 2010
Trauma is the most common reason for amputation of the upper extremity. The morphologic and functional distinctions between the upper and lower extremities render the surgical techniques and decision-making different in many key respects. Acceptance of the prosthesis and the outcomes are improved by performing a transradial rather than a more proximal amputation. Substantial efforts, including free tissue transfers when necessary, should be made to salvage the elbow. Careful management of the peripheral nerves is critical to minimize painful neuroma formation while preserving options for possible future utilization in targeted muscle reinnervation and use of a myoelectric prosthesis. Rapid developments with targeted muscle reinnervation, myoelectric prostheses, and composite tissue allotransplantation may dramatically alter surgical treatment algorithms in the near future for patients with severe upper-extremity trauma.
Critical analysis of upper limb replantations Análise crítica dos reimplantes no membro superior
Objective: The authors analyze the follow-up of results in 62 adult patients who had traumatic amputations in the upper limb and who underwent successful replantation procedures from 1994 to 2004. Methods: The levels of amputation were in fingers or thumb in 48, hand in 5, wrist in 4, forearm in 2 and arm in 3 patients. All patients were treated in a rehabilitation program of specialized hand therapy. A simplified questionnaire was used to evaluate the return to work activities using the operated limb, either in the formal or informal economy, and the patient's satisfaction rate concerning the surgical procedure. Results: It was noted that 85.5% of patients returned to some work activity using the operated limb and 96.8% of patients are satisfied with the results. Conclusions: Patients submitted to successful replantation present a high rate of satisfaction and return to work activities.
