Abstract
Background and Objective Digital replantation for traumatic amputation has become the standard of care with advances in microsurgical techniques and technology. While digital replantation has progressed significantly, there are still gaps in knowledge in many aspects. Some of the controversial topics in digital replantation include the indications and contraindications, anesthesia, number of vessel anastomoses, mechanism of injury, role of vein graft, distal fingertip replantation, and postoperative management. This article is a narrative review that discusses these controversies and current issues pertaining to digital replantation. Methods PubMed, Web of Science, and Google scholar were searched using keywords relating to "digit replantation", "amputation", and "digital replant" with the following terms: "indications", "contraindications", "anaesthesia", "survival", "vessels", "mechanism of injury", "vein graft", "outcome", and "thrombophylaxis". Relevant articles pertaining to digital replantation and deemed by the authors as current or controversial were included. Key Content and Findings The reported survival rates of digital replantation are high. With the advancement of microsurgical techniques and technology, the boundaries of digital replantation continue to be pushed. Various methods have been described recently to improve the success rates of difficult replants, such as strategies for venous outflow and vein grafting. However, there are still aspects of digital replantation that remain unanswered, such as the number of veins to anastomose and the thromboprophylaxis regime. Conclusions The review delves into controversial aspects of digital replantation, including contraindications, anesthesia, and postoperative management. Indications and contraindications will continue to evolve alongside advancements in microsurgical techniques and anesthesia. It highlights key factors influencing survival rates, such as the number of repaired vessels and the mechanism of injury. Finally, the review consolidates strategies for managing challenging digital replantations.

Abstract
INTRODUCTION A common consideration for replantation success is the ischemia time following injury and the preservation temperature. A classic principle within the hand surgery community describes 12 hours of warm ischemia and 24 hours of cold ischemia as the upper limits for digit replantation; however, these limits are largely anecdotal and based on older studies. We aimed to compare survival data from the large body of literature to aid surgeons and all those involved in the replantation process in hopes of optimizing success rates. METHODS The PubMed database was queried on April 4th, 2023, for articles that included data on digit replantation survival in terms of temperature of preservation and ischemia time. All primary outcomes were analyzed with the Mantel-Haenszel method within a random effects model. Secondary outcomes were pooled and analyzed using the chi-square statistic. Statistical analysis and forest plot generation were completed with RevMan 5.4 software with odds ratios calculated within a 95% confidence interval. RESULTS Our meta-analysis identified that digits preserved in cold ischemia for over 12 hours had significantly higher odds of replantation success than the amputated digits replanted with 0-12 hours of warm ischemia time ( P ≤ 0.05). The odds of survival in the early (0-6 hours) replantation group were around 40% greater than the later (6-12 hours) replantation group ( P ≤ 0.05). Secondary outcomes that were associated with higher survival rates included a clean-cut amputation, increased venous and arterial anastomosis, a repair that did not require a vein graft, and replants performed in nonsmokers ( P ≤ 0.05). DISCUSSION Overall, these findings suggest that when predicting digit replantation success, time is of the essence when the digit has yet to be preserved in a cold environment. This benefit, however, is almost completely diminished when the amputated digit is appropriately maintained in a cold environment soon after injury. In conclusion, our results suggest that there is potential for broadening the ischemia time limits for digit replant survival outlined in the literature, particularly for digits that have been stored correctly in cold ischemia.

Clin Orthop Relat Res 2024; 482:843-853. [PMID: 37921614 PMCID: PMC11008649 DOI: 10.1097/corr.0000000000002906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 09/29/2023] [Indexed: 11/04/2023]
Abstract
BACKGROUND Replantation is an established treatment for traumatic upper extremity amputation. Only a few studies, however, have assessed the patient-reported outcomes of replantation, and the findings of these studies have been conflicting. QUESTIONS/PURPOSES (1) Is replantation associated with better hand function than revision amputation? (2) Is replantation associated with better health-related quality of life, less painful cold intolerance, and more pleasing hand esthetics than revision amputation after a traumatic hand amputation? METHODS In this retrospective, comparative study, we collected the details of all patients who sustained a traumatic upper extremity amputation and were treated at the study hospital. Between 2009 and 2019, we treated 2250 patients, and we considered all patients who sustained a traumatic amputation of two or more digital rays or a thumb as potentially eligible. Based on that, 15% (334 of 2250) were eligible; a further 2% (8 of 334) were excluded because of a subsequent new traumatic amputation or bilateral amputation, and another 22% (72 of 334) refused participation, leaving 76% (254 of 334) for analysis here. The primary outcome was the DASH score. Secondary outcomes included health-related quality of life (EuroQOL-5D [EQ-5D-5L] Index), painful cold intolerance (the Cold Intolerance Symptom Severity score), and hand esthetics (the Michigan Hand Questionnaire aesthetic domain score). The minimum follow-up time for inclusion was 18 months. Patients were classified into two treatment groups: replantation (67% [171 of 254], including successful replantation in 84% [144 of 171] and partially successful replantation in 16% [27 of 171], in which some but not all of the replanted tissue survived), and revision (complete) amputation (33% [83 of 254], including primary revision amputation in 70% [58 of 83] and unsuccessful replantation followed by secondary amputation in 30% [25 of 83]). In this cohort, replantation was performed if possible, and the reason for choosing primary revision amputation over replantation was usually an amputated part that was too severely damaged (15% [39 of 254]) or was unattainable (2% [4 of 254]). Some patients (3% [8 of 254]) refused to undergo replantation, or their health status did not allow replantation surgery and postoperative rehabilitation (3% [7 of 254]). Gender, age (mean 48 ± 17 years in the replantation group versus 50 ± 23 years in the revision amputation group; p = 0.41), follow-up time (8 ± 4 years in the replantation group versus 7 ± 4 years in the revision amputation group; p = 0.18), amputation of the dominant hand, smoking, extent of tissue loss, or presence of arterial hypertension did not differ between the groups. Patients in the replantation group less frequently had diabetes mellitus (5% [8 of 171] versus 12% [10 of 83]; p = 0.03) and dyslipidemia (4% [7 of 171] versus 11% [9 of 83]; p = 0.04) than those in the revision group and more often had cut-type injuries (75% [129 of 171] versus 60% [50 of 83]; p = 0.02). RESULTS After controlling for potential confounding variables such as age, injury type, extent of tissue loss before treatment, and accident of the dominant hand, replantation was not associated with better DASH scores than revision amputation (OR 0.82 [95% confidence interval (CI) 0.50 to 1.33]; p = 0.42). After controlling for potential cofounding variables, replantation was not associated with better EQ-5D-5L Index scores (OR 0.93 [95% CI 0.56 to 1.55]; p = 0.55), differences in Cold Intolerance Symptom Severity scores (OR 0.85 [95% CI 0.51 to 1.44]; p = 0.79), or superior Michigan Hand Questionnaire esthetic domain scores (OR 0.73 [95% CI 0.43 to 1.26]; p = 0.26) compared with revision amputation. CONCLUSION Replantation surgery was conducted, if feasible, in a homogenous cohort of patients who underwent amputation. If the amputated tissue was too severely damaged or replantation surgery was unsuccessful, the treatment resulted in revision (complete) amputation, which was not associated with worse patient-reported outcomes than successful replantation. These results contradict the assumed benefits of replantation surgery and indicate the need for credible evidence to better guide the care of these patients. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Distal fingertip replantation is associated with being a technically demanding procedure and dubious outcomes, although it is now performed more frequently across the world. However, the technique and outcomes remain controversial with disagreement among replantation surgeons due to lack of consensus about the indications, intraoperative strategy and postoperative regimes. In this article, we asked six experienced hand surgeons several pertinent questions that every replantation surgeon performing distal fingertip replantation would face in their clinical practice. The article summarizes their responses, which might provide valuable insight to every replantation surgeon in different parts of their career while managing these injuries.

Abstract
Injuries to the nail complex are common in children. Most children who present with fingertip trauma have experienced a crush injury, usually from the hinge side of a door and often in the living room. This article reviews the literature on the management of fingertip crush injuries, fractures of the distal phalanx, nail bed injury and subungual hematoma to establish, where possible, best evidence.

Abstract
Background Revascularization surgery has been reported to have a higher success rate than replantation due to sufficient venous return. However, in complex cases, success depends on a wide range of indications. This study aimed to investigate success rates in cohorts that included severe cases. Methods This single-center, noninterventional, retrospective cohort study included 292 patients (349 digits) who underwent revascularization or replantation at our institution between January 2000 and December 2022. Sex, age, smoking history, comorbidities, affected digit, amputation level, complete or incomplete amputation, type of fracture and mechanism, artery diameter, needle, vein anastomosis in the revascularization subgroup, vein grafting, warm ischemic time, and outcomes were investigated and compared between the revascularization and replantation subgroups of the distal and proximal amputation groups. Results In the distal amputation group, the arterial diameter in the revascularization subgroup was larger than that in the replantation subgroup (P < 0.05). In the proximal amputation group, the revascularization subgroup had a lower frequency of multiple amputations than the replantation subgroup (P < 0.05). Vein grafts were more frequently used in both revascularization subgroups than in the replantation subgroups (P < 0.05). However, the other injury severity indices were similar, and the success rates were not significantly different between the subgroups. Conclusions The revascularization success rate was similar to that of replantation. Vein anastomosis or vein grafting to the veins should be advocated for revascularization in severe cases where skin bridges may not have sufficient venous return.

Abstract
PURPOSE Digit-tip amputation caused by crush injury is a common emergency scenario, and the management is full of challenges. The objective of this study was to demonstrate the application of the supermicrosurgery technique in replantation procedures for complex digit-tip amputations resulting from crush injuries, while also assessing functional and aesthetic outcomes. METHODS We conducted a retrospective analysis of the data from 12 patients who underwent replantation of 15 digits in our department between July 2022 and June 2023. The outcomes of replantation, functional recovery (including return to work, cold tolerance, bone union, DASH score, VAS score, and two-point discrimination test), aesthetic results (including digit appearance, nail deformity, and pulp atrophy), and patient satisfaction were assessed. RESULTS The amputation of 7 digits occurred within Tamai zone I level, 8 digits within Tamai zone II level, while 4 digits occurred within Ishikawa zone I level, 3 digits within Ishikawa zone II level, 7 digits within Ishikawa zone III level, and 1 digit within Ishikawa zone IV level. The replanted digits all survived (100%) without any indications of arterial insufficiency or venous congestion. The follow-up procedures were conducted on all 12 patients, with an average duration of 9.6 months (range, 6 to 18 months). The fracture successfully underwent healing at 9.2 weeks (range, 8 to 13 weeks). The mean VAS score was 1.75 points (range 0 to 4 points), the mean two-point discrimination test result was 5.72 mm (range 4.0 to 7.0 mm), and the mean DASH score was 9.78 points (range 3.33 to 22.5 points). All patients demonstrated cold tolerance and successfully resumed their pre-injury occupational activities. The nail deformity was observed in one digit following replantation within Tamai zone I, and in three digits following replantation within Tamai zone II; moreover, eight digits exhibited varying degrees of pulp atrophy. All patients expressed satisfaction with both functional and aesthetic outcomes. CONCLUSION The successful replantation of digit-tip amputation caused by crush injury can be achieved through the application of supermicrosurgery technique, resulting in improved functional and aesthetic outcomes. Digit-tip replantation is a favorable and meaningful procedure with high patient satisfaction.

Abstract
Background Children have been suggested to benefit from digit replantation due to a greater neurogenerative capacity. We aimed to conduct a systematic review on digit replantation in children to provide a comprehensive overview of survival rates and functional outcomes. Methods A systematic literature search was conducted on Ovid MEDLINE, Embase, and the Cochrane Controlled Register of Trials for studies published between 1980 and 2023. We included peer-reviewed studies reporting on digit survival rates in pediatric patients under the age of 18 years who underwent single or multiple digit replantations distal to the metacarpophalangeal joint. Preoperative, intraoperative, and postoperative outcomes were extracted, and pooled estimates were derived using univariable analysis. Results Twenty-two studies reporting on 761 patients and 814 digit replantations were included in our study. Most replantations occurred in the index (n = 74), Tamai zone I (n = 168), and from clean-cut injuries (n = 190). The mean survival rate was 76% (n = 618/814), with a mean range of motion at the distal interphalangeal joint ranging from 64 degrees to 90 degrees and two-point discrimination ranging from 3.8 mm to 6.4 mm. Compared with clean-cut injuries, digit replantations from avulsion [odds ratio (OR), 0.81; 95% confidence interval (CI), 0.74-0.89] or crush (OR, 0.71; 95% CI, 0.59-0.82) injuries were associated with a lower odds of survival. Digit replantations performed with two venous (OR, 1.43, 95% CI; 1.28-1.59) or arterial anastomoses (OR, 1.65; 95% CI, 1.48-1.81) were associated with a higher odds of survival. Conclusions Our systematic review suggests that digit replantation may be a viable option in children. Further research is required to explore functionality after digit replantation in diverse pediatric populations.

Abstract
PURPOSE The requirement for anatomic venous reconstruction in digit replantation is an ongoing area of research. In this study, we evaluated our institutional experience to study whether replantation success is affected by the presence or absence of vein repair, stratified by the level of injury. METHODS A retrospective review was performed at an urban, level-1 trauma center of all single-digit replantations performed in adults from 2012 to 2021. Patient demographics, injury mechanism, level of injury, whether a vein was repaired, and replant survival were recorded. RESULTS Sixty-seven single replanted digits were included. Patients were, on average, 38 years old, and 94% were men. The most common mechanism of injury was a sharp laceration (81%). The overall survival rates for all replantations were 68.7% (46/67) and 60% (12/20) for distal finger replantation. Patients with digital replantations at Tamai zone III or more proximal exhibited a 1.8 times increase in survival rates when one vein was repaired versus zero veins (84.4% vs 46.7%). Patients with digital replantations at Tamai zones I and II exhibited similar survival rates. CONCLUSIONS Replantations at or proximal to the middle phalanx should be repaired with at least one artery and vein to maximize the chance for success. However, for distal finger replantations, artery-only replantation is a viable option when vein anastomosis is not achievable. TYPO OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Surgical and patient-reported outcomes in an Asian female population with or without adjuvant radiotherapy after immediate free perforator flap breast reconstruction: A retrospective review. JPRAS Open 2023; 38:237-248. [PMID: 38021323 PMCID: PMC10630550 DOI: 10.1016/j.jpra.2023.09.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 09/05/2023] [Indexed: 12/01/2023] Open
Abstract
Background The majority of English literature has reported on the somewhat conflicted outcomes of the effect of radiotherapy on immediate breast reconstruction. However, data specifically related to patients of Asian descent has been scarce. This retrospective study aims to shed light on this topic to aid in the management of this group of patients. Methods All patients who received immediate free perforator flap-based breast reconstruction under a single surgeon over a 10-year period were included in the study. Patient characteristics, oncological and surgical data were collected. Patients were divided into post-mastectomy radiotherapy (PMRT) and non-PMRT groups. The final aesthetic outcome was assessed by a surgeon-reported outcome questionnaire. Patient satisfaction and psychological outcomes were assessed using validated patient-reported outcome (PRO) questionnaire (BREAST-Q), breast reconstruction, and postoperative module. Results A total of 101 women, with an average age of 44.7 ± 8.4 underwent perforator flap-based reconstruction. Fifteen patients received PMRT, with remaining 86 patients in the non-PMRT group. The mean duration of follow-up was over 5 years (p = 0.514). The recurrence rate was acceptable in the PMRT group (3/15, p = 0.129). There were no significant differences in complication rates between the two groups (p = 1.000). The aesthetic outcomes were comparable (p = 0.342). PRO appears to be lower in the PMRT group. Conclusions Immediate breast reconstruction with PMRT in the local patient cohort is oncologically safe, acceptable complication profile, revision rate, and aesthetic outcome. PRO showed lower scores in several categories, which differ from normative data generated in the Western population. Further studies will need to examine the confounding effects of radiation in this specific population.

Abstract
BACKGROUND Antegrade homodigital neurovascular island flap (AHIF) is one of the methods used in fingertip amputations to cover the defect area, preserve finger length and obtain a painless and sensitive fingertip. The aim of this study was to evaluate the functional and sensory outcomes in patients who underwent AHIF for fingertip amputation and to analyze the relationship between patient satisfaction and outcome measures. METHODS Twenty patients with a mean age of 37 (18-63) years were analyzed retrospectively. The patients were evaluated in terms of hook nail development, active interphalangeal joint movements, cold intolerance, and sensory function of the flap covered area. Static two-point discrimination test and Semmes Weinstein monofilament test were performed for sensory evaluation. RESULTS All flaps survived completely at the end of follow-up (mean, 36 months; range 11-64 months). Five patients had cold intolerance and two had hook nails. In total, proximal interphalangeal or distal interphalangeal joint flexion contracture developed in 25 % of the patients. The mean static two-point discrimination score was 4.6 ± 1.6 (2-8) and Semmes-Weinstein monofilament test score was 3.48 ± 0.6 (2.44-4.17). Subjective satisfaction levels of the patients were found to be high and did not show a statistical relationship with the measured clinical outcome parameters (p > 0.05). CONCLUSIONS Since AHIF contains a solid and continuous neurovascular pedicle, the probability of necrosis and loss of sensation is low in AHIF. In addition, the graft need of the donor area is not high. Its disadvantage is the rate of restriction of joint movements. LEVEL OF EVIDENCE IV.

Abstract
The ability to perform surgical replantation of individual digits and limbs can provide substantial functional improvement for patients who sustain devastating upper extremity injuries. Defining success in replantation surgery extends beyond the acute period and the binary metrics of survival or loss of the replanted part to include the long-term overall functional outcomes. Functional outcomes include both objective clinical evaluation and patient-reported outcomes. There has been significant variation in the way outcomes following replantation are measured, which inherently leads to heterogeneity in the reported outcome data. Given the variability among outcome measures, we aim to explore the outcomes of replantation surgery, particularly clinical evaluation and patient-reported functional outcomes following replantation.

Abstract
PURPOSE The replantation of multiple amputated digits is a technically challenging procedure for reconstructive surgeons that requires more time than the replantation of a single digit. We evaluated the effect of multiple-digit replantation on the success of digital replantation. METHODS Patients who experienced digital amputation and underwent digital replantation from January 2018 to December 2021 were studied retrospectively. Patients who experienced successful and failed replantation were compared, as were digits that survived or became necrotic after replantation. A multivariate logistic regression (MLR) analysis was performed to evaluate the independent factors of replanted digit survival. RESULTS There were 378 patients with 497 amputated digits who underwent digital replantation. Of all 378 patients, 298 underwent single-digit replantation, and the other 80 patients underwent multiple-digit replantation. A total of 83.3% of the replanted digits survived (414 of 497). Compared with patients with surviving replanted digits, significantly more patients with necrotic replanted digits underwent multiple-digit replantation (37.7% vs. 17.5%, p < 0.001). On the other hand, a digit that developed necrosis after replantation was more likely to have been involved in the replantation of three or more digits (16% vs. 29%, p = 0.005). The subsequent MLR analysis revealed that the likelihood of necrosis was 2.355 (p = 0.003) times higher in the replantation of three or more digits than in the replantation of one or two digits. CONCLUSION Patients who underwent multiple-digit replantation exhibited a higher incidence of necrosis in the replanted digits. In cases involving patients with multiple-digit amputation, it is crucial to prioritize and perform selective replantation based on the amputated digits.

Abstract
Background The clinical results of replantation for an amputated distal finger are functionally acceptable. However, few reports exist regarding sequential clinical postoperative recovery. The purpose of this study was to examine the clinical recovery at every 3 months up to 1 year postoperatively. Methods Nineteen patients (16 patients were men), representing 19 fingers with complete amputation at Tamai's zone 1 and replanted successfully, were included in this study. Total active motion (TAM), grip strength (GS), Semmes-Weinstein monofilament (SW) test result, static two-point discrimination (s2PD), and Disability of the Arm, Shoulder, and Hand (DASH) score questionnaire results were obtained postoperatively at 3, 6, 9, and 12 months. Pulp atrophy and nail deformity were assessed at 12 months postoperatively. Results The postoperative %TAM (compared to the uninjured side, 81.8 ± 18.1 at 3 months vs. 91.5 ± 11.9 at 6 months, p < 0.01), %GS (compared with the uninjured side, 61.3 ± 25.9 at 3 months vs. 78.3 ± 20.4 at 6 months, p = 0.02), s2PD (excellent and good/poor; 7/12 at 3 months vs. 18/1 at 6 months, p < 0.01), and DASH scores (26.1 ± 23.1 at 3 months vs. 12.0 ± 12.9 at 6 months, p < 0.01) recovered significantly from 3 to 6 months but did not change significantly from 6 months onward. The SW test results showed a significant recovery between 3 and 12 months postoperatively (2.83 and 3.61/4.31, 6.65, and undetectable, 1/18 at 3 months vs. 7/12 at 12 months, p = 0.04). The DASH score at 12 months postoperatively was significantly associated with %TAM ( r = -0.64, p < 0.01) and %GS ( r = -0.58, p < 0.01) at 12 months postoperatively and age ( r = 0.52, p = 0.02). Five fingers had pulp atrophy and four fingers had nail deformity. Conclusion This 1-year follow-up study showed the sequential clinical recovery after replantation for complete amputation in Tamai zone 1. Postoperative %TAM, %GS, and the DASH score recovered significantly between 3 and 6 months but significant recovery up to 1 year was not observed.

Abstract
Since the advent of replantation techniques, there has been uneven progress in terms of success-even considering whether success is defined as continued perfusion of the digit or long term functional outcomes. Early enthusiasm and success have not been maintained despite increasing familiarity with microsurgical techniques and greater understanding of how to optimize outcomes for the individual components of replantation such as tendon repair, nerve repair, and osteosynthesis. Practitioners participating in the care of patients undergoing replantation should be familiar with the history and current understanding of both the indications and contraindications for the procedure, post-operative rehabilitation, and factors contributing to functional outcomes. A review of the literature from the first publications on the topic demonstrates evolution in practice and understanding of which patients should be indicated for replantation. Indications can be considered in three broad categories: injury factors, patient factors, and care context factors. These factors intersect with one another and can inform the surgeon pre-operatively regarding the most likely outcome for a given patient. This insight is critical to discuss pre-operatively with the patient in order to make a shared decision about how to manage their injury.

Clin Orthop Relat Res 2023; 481:1583-1594. [PMID: 36795073 PMCID: PMC10344486 DOI: 10.1097/corr.0000000000002578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 01/06/2023] [Indexed: 02/17/2023]
Abstract
BACKGROUND Ensuring the patency of repaired vessels is pivotal in improving the success rate of digit replantation. There is no consensus on how to best approach postoperative treatment for digit replantation. The influence of postoperative treatment on the risk of failure of revascularization or replantation remains unclear. QUESTIONS/PURPOSES (1) Is there an increased risk of postoperative infection with early discontinuation of antibiotic prophylaxis? (2) How are anxiety and depression affected by a treatment protocol consisting of prolonged antibiotic prophylaxis and administration of antithrombotic and antispasmodic drugs and by the failure of a revascularization or replantation procedure? (3) Are there differences in the risk of revascularization or replantation failure based on the number of anastomosed arteries and veins? (4) What factors are associated with failure of revascularization or replantation? METHODS This retrospective study was conducted between July 1, 2018, and March 31, 2022. Initially, 1045 patients were identified. One hundred two patients chose revision of amputation. In all, 556 were excluded because of contraindications. We included all patients in whom the anatomic structures of the amputated part of the digit were well preserved, and those with an ischemia time for the amputated part that did not exceed 6 hours. Patients in good health without any other serious associated injuries or systemic diseases and those without a history of smoking were eligible for inclusion. The patients underwent procedures that were performed or supervised by one of four study surgeons. Patients were treated with antibiotic prophylaxis (1 week); patients treated with antithrombotic and antispasmodic drugs were categorized into the prolonged antibiotic prophylaxis group. The remaining patients treated with antibiotic prophylaxis for less than 48 hours and no antithrombotic and no antispasmodic drugs were categorized into the nonprolonged antibiotic prophylaxis group. Postoperative follow-up was for a minimum of 1 month. Based on the inclusion criteria, 387 participants with 465 digits were selected for an analysis of postoperative infection. Twenty-five participants with a postoperative infection (six digits) and other complications (19 digits) were excluded from the next stage of the study, in which we assessed factors associated with the risk of failure of revascularization or replantation. A total of 362 participants with 440 digits were examined, including the postoperative survival rate, variation in Hospital Anxiety and Depression Scale scores, the association between the survival rate and Hospital Anxiety and Depression Scale scores, and the survival rate based on the number of anastomosed vessels. Postoperative infection was defined as swelling, erythema, pain, purulent discharge, or a positive bacterial culture result. Patients were followed for 1 month. The differences in anxiety and depression scores between the two treatment groups and the differences in anxiety and depression scores based on failure of revascularization or replantation were determined. The difference in the risk of revascularization or replantation failure based on the number of anastomosed arteries and veins was assessed. Except for statistically significant variables (injury type and procedure), we thought that the number of arteries, number of veins, Tamai level, treatment protocol, and surgeons would be important. A multivariable logistic regression analysis was used to perform an adjusted analysis of risk factors such as postoperative protocol, injury type, procedure, number of arteries, number of veins, Tamai level, and surgeon. RESULTS Postoperative infection did not appear to increase without prolonged use of antibiotic prophylaxis beyond 48 hours (1% [3 of 327] versus 2% [3 of 138]; OR 2.4 [95% confidence interval (CI) 0.5 to 12.0]; p = 0.37). Intervention with antithrombotic and antispasmodic therapy increased the Hospital Anxiety and Depression Scale scores for anxiety (11.2 ± 3.0 versus 6.7 ± 2.9, mean difference 4.5 [95% CI 4.0 to 5.2]; p < 0.01) and depression (7.9 ± 3.2 versus 5.2 ± 2.7, mean difference 2.7 [95% CI 2.1 to 3.4]; p < 0.01). In the analysis based on the failure of revascularization or replantation, the Hospital Anxiety and Depression Scale scores for anxiety (11.4 ± 4.4 versus 9.7 ± 3.5, mean difference 1.7 [95% CI 0.6 to 2.8]; p < 0.01) and depression (8.5 ± 4.6 versus 7.0 ± 3.1, mean difference 1.5 [95% CI 0.5 to 2.5]; p < 0.01) were higher in the failed revascularization or replantation group than in the successful revascularization or replantation group. There was no increase in the artery-related risk of failure (one versus two anastomosed arteries: 91% versus 89%, OR 1.3 [95% CI 0.6 to 2.6]; p = 0.53). For patients with anastomosed veins, a similar outcome was observed for the two vein-related risk of failure (two versus one anastomosed vein: 90% versus 89%, OR 1.0 [95% CI 0.2 to 3.8]; p = 0.95) and three vein-related risk of failure (three versus one vein anastomosed: 96% versus 89%, OR 0.4 [95% CI 0.1 to 2.4]; p = 0.29). Factors associated with failure of revascularization or replantation included the mechanism of injury (crush: OR 4.2 [95% CI 1.6 to 11.2]; p < 0.01, avulsion: OR 10.2 [95% CI 3.4 to 30.7]; p < 0.01). Revascularization had a lower risk of failure than replantation (OR 0.4 [95% CI 0.2 to 1.0]; p = 0.04). Treatment with a protocol of prolonged antibiotics, antithrombotics, and antispasmodics was not associated with a lower risk of failure (OR 1.2 [95% CI 0.6 to 2.3]; p = 0.63). CONCLUSION With proper wound debridement and patency of repaired vessels, prolonged use of antibiotic prophylaxis and regular antithrombotic and antispasmodic treatment may not be necessary for successful digit replantation. However, it may be associated with higher Hospital Anxiety and Depression Scale scores. Postoperative mental status is associated with digit survival. Well-repaired vessels, instead of the number of anastomosed vessels, could be critical to survival and decrease the influence of risk factors. Further research on consensus guidelines that compare postoperative treatment and the surgeon's level of expertise after digit replantation should be conducted at multiple institutions.

Abstract
BACKGROUND Digit amputations are relatively simple and are often performed in the setting of trauma or infection. However, it is not uncommon for digit amputations to undergo secondary revision due to complications or patient dissatisfaction. Identifying factors associated with secondary revision may alter treatment strategy. We hypothesize that the secondary revision rate is affected by digit, initial level of amputation, and comorbidities. METHODS A retrospective chart review was conducted on patients undergoing digit amputations in operating rooms at our institution from 2011 to 2017. Secondary revision amputations were defined as a separate return to the operating room following initial surgical amputation, excluding emergency room amputations. Patient demographics, comorbidities, level of amputation, and complications were collected. RESULTS In all, 278 patients were included with a total of 386 digit amputations and mean follow-up of 2.6 months. Three hundred twenty-six primary digit amputations were performed in 236 patients (group A). Sixty digits were secondarily revised in 42 patients (group B). The secondary revision rate was 17.8% for patients and 15.5% for digits. Patients with heart disease and diabetes mellitus were associated with secondary revision, with wound complications being the leading indication overall (73.8%). Medicare covered 52.4% of patients in group B versus 30.1% in group A (P = .005). CONCLUSION Risk factors for secondary revision include Medicare insurance, comorbidities, previous digit amputations, and initial amputation of either the index finger or the distal phalanx. These data may serve as a prediction model to aid surgical decision-making by identifying patients at risk of secondary revision amputation.

Abstract
BACKGROUND This study aimed to classify fingertip defects according to dimensions and composite content, and present algorithmic reconstruction results with free lateral great-toe flaps. METHODS A total of 33 patients who underwent reconstruction for full-thickness defects of fingertips with free lateral great-toe flaps were retrospectively reviewed. Patients were divided into four groups by the algorithm according to the dimension and content of defects. Functional disabilities of the upper extremities, limitations of donor feet, finger cosmetics, sensory recovery, and pinch power were evaluated using the disabilities of the arm, shoulder and hand, foot function index, 5-point Likert satisfaction scales, Semmes-Weinstein monofilament and static 2-point discrimination tests, and pulp pinch-strength test, respectively. RESULTS The standardized distribution of patients according to dimensions and content of defects was achieved. When the composite content of defects increase such as group 4, complex surgical skills are required, duration of surgery is extended, return to work is delayed, and donor-site complications are increased. Functional limitations of the hands improved normally after reconstruction (p < 0.00). Sensory recovery of flaps was normal and test scores were strongly correlated (p = 0.78). All patients and observers were satisfied with finger's cosmetics. CONCLUSION Our classification and reconstruction algorithm is simple and easy to apply for all fingertip defects without complicated reference points, and it provides information about the surgical and post-surgical periods. When the dimension and composite deformities of the defect increase through groups 1-4, more complex reconstruction, increased donor-site complications, prolonged duration of surgery, and delayed return to work are observed.

PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e4992. [PMID: 37235131 PMCID: PMC10208696 DOI: 10.1097/gox.0000000000004992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 03/20/2023] [Indexed: 05/28/2023]
Abstract
No difference in the success rate has been reported between the vein graft and non-vein graft groups in replantation/revascularization. However, this depends on a wide range of indications in difficult cases. This study aimed to investigate the selection bias in avoiding vein grafts. Methods This is a single-center, noninterventional, retrospective cohort study comprising 229 patients (277 digits) who underwent replantation/revascularization between January 2000 and December 2020 at our institution. Sex, age, smoking history, comorbidities, affected side, level of amputation, complete or incomplete amputation, type of fracture and mechanism, diameter of the artery, needle, warm ischemic time, and results were investigated and compared between the subgroups with and without vein graft. Results were investigated between the subgroups with and without a vein graft in the distal and proximal groups. Results In the distal group, the mean arterial diameter of the vein graft subgroup was larger than that of the non-vein graft subgroup [0.7 (0.1) mm and 0.6 (0.2) mm, respectively, P < 0.05]. In the proximal group, the vein graft subgroup had higher severity than the non-vein graft subgroup (comminuted fracture, 31.1% versus 13.4%; and avulsion or crush amputation, 57.8% versus 37.1%, respectively, P < 0.05). However, the success rate was not significantly different between the aforementioned subgroups. Conclusion There was no significant difference between the vein graft and non-vein graft subgroups owing to the selection bias avoiding small arteries in the distal amputation and the absence of said bias in the proximal amputation.

Abstract
With the advent of supermicrosurgery, the replantation of very distal finger amputations has become possible. The choice between replantation or flap surgeries in the treatment of Tamai Zone I finger amputations continues to be a matter of debate. This study aims to evaluate replantation results in Tamai Zone 1 finger amputations. The demographic characteristics and clinical results of 39 patients undergoing replantation for a Tamai Zone 1 finger amputation between 2018 and 2021 were retrospectively analyzed. The Cold Intolerance Severity Score (CISS), two-point discrimination test (2-PD) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) were calculated and recorded after a minimum follow-up period of 6 months. The great majority of patients were males (92.3%, n=36) who had suffered the injuries during work accidents (89.7%, n=35). The socioeconomic status of the patients showed a homogeneous distribution. Replant survival was achieved in 69.2% (n=27) of all fingers. The duration of the surgical procedure in patients who underwent vein repair was significantly longer (p<0.001). However, there was no significant relationship between vein repair and survival rate (p=0.348). This study shows that replantation is a surgical intervention that should be given priority in patients with Tamai Zone 1 amputations. In most cases of unsuccessful replantation, secondary recovery results are also acceptable. Future studies with larger case series are needed.

Abstract
Purpose: Understanding the variables that influence success in digital replant surgery is essential to guide clinical decision-making and to counsel patients. The purpose of this study was to determine the replant success rate and identify predictors of success at our tertiary care centre. Methods: This was a single centre, retrospective cohort study of consecutive patients who underwent digital replantation from January 2000 to September 2018. Adult patients with flexor zone I to III amputations were included. Patient demographics, comorbidities, injury pattern, operative data, and post-operative care were reviewed. The primary outcome was survival of the replanted digit at discharge. Results: A total of 146 patients met inclusion criteria. Of these, 100 had single-digit replants and 46 underwent multi-digit replants for a total of 220 digits. The success rate was 71%. Predictors of success included sharp mechanism of injury (P < .01), incomplete amputation (P < .01), amputation proximal to zone I flexor level (P = .02), post-operative acetylsalicylic acid use (P < .01), absence of leech use (P = .05), and absence of operative re-exploration (P < .01). Daytime replants had similar outcome compared to nighttime replants despite having increased ischemia time (7.9 ± 3.9 hours vs 6.8 ± 2.6 hours, P = .02). However, daytime operative time (7.8 ± 3.7 hours) was significantly shorter than nighttime replant time (9.6 ± 5.9 hours, P = .01). Conclusion: Sharp amputation, intact venous drainage, proximal amputation, and acetylsalicylic acid use were associated with replant survival and are factors to consider when managing patients for digital replantation. Leech therapy and operative re-exploration were associated with poor outcome. Nighttime replants required significantly longer operative time than daytime replants despite similar survival outcome.

Abstract
BACKGROUND Microsurgical replantation of fingertip amputation is sometimes difficult because of a lack of available vessels. Composite grafting is an alternative method for nonvascularized replantation, but it has a limited success rate. The subdermal pocket (SDP) procedure is proposed to increase the survival of composite graft. AIM AND OBJECTIVES We aimed to compare the success rate of the composite graft used in fingertip replantation with or without application of the SDP procedure. PATIENTS AND METHODS From 2000 to 2020, 29 fingertip amputations (28 complete amputations, 1 near-complete amputation) from 28 patients were included. Five of the fingertip amputations were classified as Ishikawa zone Ib and 24 as Ishikawa zone II. Seventeen fingers underwent replantation with composite graft plus SDP procedure, whereas the remaining 12 fingers received replantation with composite graft only. RESULTS The overall success rate was 70.59% (12 of 17) in the SDP group and 41.67% (5 of 12) in the composite graft-only group (P = 0.119; odds ratio, 3.36). In the subgroup of Ishikawa zone II fingertip amputations, the success rate was 66.67% (10 of 15) in the SDP group and 22.22% (2 of 9) in the composite graft-only group (P = 0.035; odds ratio, 7.0). CONCLUSIONS The SDP procedure could increase the success rate of fingertip replantation with composite graft, especially for Ishikawa zone II amputations.

Abstract
The management of complex upper extremity trauma can be overwhelming in its urgency and complexity. Having a systematic approach that maintains a clear set of priorities focused on hand and upper extremity function, operative efficiency, and long-term planning for future operations allows the reconstructive extremity surgeon to effectively treat these complex injuries. This article addressed these overall clinical considerations and details the approach taken at the Buncke Clinic including replantation and revascularization as well as osseous and soft tissue reconstruction.

Abstract
BACKGROUND A single digit amputated proximal to the flexor digitorum superficialis (FDS) insertion is a relative contraindication to replantation. The aim of this study is to conduct a systematic review on replantation of these injuries to synthesize best available evidence on outcomes. METHODS This review was registered in PROSPERO under registration number CRD42021277305. A MEDLINE, CENTRAL, and EMBASE databases search yielded 1536 studies. Primary clinical studies on single digit replantation and functional outcome with at least 10 cases were included. Data on revision amputation and replantation distal to the FDS were collected as comparators. Data extracted included demographics, type of digit, level of injury, secondary surgeries, duration of sick leave, survival, function, and patient-reported outcomes. All studies were assessed using the Risk of Bias In Non-randomized Studies of Intervention (ROBINS-I) tool and data synthesis was completed using RevMan and Microsoft Excel. RESULTS Six studies representing 182 replanted single digits that were amputated proximal to the FDS insertion were included. The average PIPJ motion of replanted single digits was 50° in those amputated proximal to the FDS insertion compared to 82.5 in those amputated distal to the FDS. The average Michigan Hand Questionnaire (MHQ) score was 84.78 in replantation group versus 76.81 in the amputation group which was statistically significant (p < .00001). Mean Disability of Arm, Shoulder, and Hand Questionnaire (DASH) score was 12 in replantation group compared to 18.5 in amputation group, however this was not statistically significant (p = .17). CONCLUSION Few studies exist on outcomes of single digit replantations proximal to FDS insertion. Although range of motion is inferior in the replant group, this has increased since initial studies were performed, and patient satisfaction and patient reported outcomes are high. This is promising evidence for achieving reasonable outcomes in replantation of single digits amputated proximal to the FDS. LEVEL OF EVIDENCE Level III.

Abstract
Amputation at the level of the distal phalanx is a common hand injury and is normally treated with replantation. However, if the level of injury is distal or the vessels of the stump have been crushed by injury, replantation cannot be a viable option. The aim of this study is to evaluate the functional and aesthetic outcomes of the “hybrid abdominal flap”, which consists of a random-pattern abdominal skin flap and an autologous bone graft. A retrospective analysis was performed on fingertip amputation patients from March 2019 to April 2021. The patients were managed by either hybrid abdominal flaps (HAFs) or homodigital neurovascular island flaps (HNIFs). The functional and aesthetic outcomes were assessed three months after the operations. In this study, a total of 20 fingers were treated with either HAFs or HNIFs. There was a significant difference in the range of motion (ROM) and the scar quality between the two groups. All of the flaps survived without flap necrosis, and non-union of the bone was not observed. The patients were satisfied with the appearance and function of their fingers, including the ROM and sensory aspects. Our novel HAF is a functionally and aesthetically valid option for fingertip amputations with crushed stumps.

Abstract
Background: Identification of the risk factors for surgical site infection (SSI) can be a straightforward and cost-effective measure to reduce or prevent the occurrence of SSI. However, there are no studies that revealed risk factors for SSI for traumatic upper extremity amputation. The aim of this study is to investigate the risk factors that promote SSI after surgery for traumatic upper extremity amputation using a large nationwide database. Methods: We used data from the Japan Trauma Data Bank. Diagnoses were defined using the Abbreviated Injury Scale code. We applied multivariate logistic regression to evaluate the infection risk factor. We chose age, sex, vital signs, cause and type of trauma, concomitant injury, diabetes, amputation level, Glasgow coma scale, Injury Severity Score (ISS) and blood transfusion within 24 hours following hospital arrival as confounders. Receiver operating characteristic (ROC) curve analysis was adopted to identify thresholds for change in infection risk. We also applied propensity score (PS) matching to adjust for confounding factors that may affect the outcome. Results: A total of 1,150 patients (967 males, 183 females) had traumatic upper extremity amputation. The mean patient age was 46.5 years. A total of 21 patients (1.8%) suffered from SSI. ISS, blood transfusion, systolic blood pressure (BP) and the upper extremity amputation except for finger were identified as the independent significant risk factors for SSI occurrence by the multivariate analysis (p < 0.05, p < 0.005, p < 0.05 and p < 0.005, respectively). ROC modelling revealed that patients with ISS of over 9 or systolic BP of over 160 had a risk for SSI. After PS matching, the patients with blood transfusion or systolic BP of over 160 had a significantly higher risk of infection (OR 9.0; p = 0.01 and OR 7.0; p = 0.03, respectively). Conclusions: In treating patients with these risk factors, we must be especially careful in performing thorough debridement and wound care. Level of Evidence: Level II (Therapeutic)

Abstract
Background The success of digit replantation is mainly based on survival rates. The functional outcome as well as the recovery of sensibility are essential parameters for judging the outcome after digit replantation but have been poorly assessed in previous studies. Patients and methods Forty-eight patients with 56 complete traumatic digit amputations occurring between 2008 and 2013 returned for a follow-up examination, the earliest being 6 months postoperatively. Each patient’s range of motion, fingertip-to-table distance, fingertip-to-palm distance, grip and pinch strengths, static two-point discrimination (2-PD), and Semmes–Weinstein monofilament (SWM) test level were assessed in order to compare functional outcome and recovery of sensibility between successful replantation (n = 19) and primary or secondary amputation (n = 37). Subjective assessments of the pain level and function of the upper extremity were performed using the numerical rating scale and the DASH score, respectively. Results Replanted digits achieved 58% of the median total range of motion of the corresponding uninjured digits. Grip and pinch strength were not significantly different after thumb or finger replantation or amputation. Recovery of sensibility was excellent after replantation, with a median static 2-PD of 5 mm and a reduction of pressure sensibility of two levels of the SWM test compared to the contralateral side. After amputation, the median static 2-PD was also very good, with a median value of 6 mm and a reduction of pressure sensibility of only one level according to the SWM test. There was significantly less pain after replantation at rest (p = 0.012) and under strain (p = 0.012) compared to patients after amputation. No significant differences were observed in the DASH score between the two groups. Conclusion Comparable functional results and sensory recovery but significantly less pain at rest and under strain can be expected after digit replantation when compared to digit amputation. Level of evidence IV.

Abstract
BACKGROUND Artery-only replantation may be necessary in circumstances when venous repair cannot be performed due to their size or vessel injury. Venous congestion of the replanted part is inevitable. A systematic review was performed to identify techniques for mitigating congestion and analyze the outcomes of those techniques. METHODS A comprehensive literature search was performed to identify relevant articles related to artery-only replantation. An initial query identified 1286 unique articles. A total of 55 articles were included in the final review. Included studies were categorized by decongestive technique. Data from each article included the number of patients treated, level of amputation, graft use, anticoagulation or antiplatelet therapy, replant viability, and follow-up duration. Weighted averages were determined from studies that reported five or more digits. RESULTS A total of 1498 individual digital replantations were described. Very rarely did studies report artery-only replantation proximal to the distal interphalangeal joint. An overall survival rate of 78.5 percent was found irrespective of technique but was variable based on each particular study. Studies utilizing medicinal leech therapy were more likely to report use of intravenous anticoagulation, whereas surface bleeding techniques were more likely to report use of topical or local anticoagulant. CONCLUSIONS Lack of a vein for anastomosis should not be regarded as a contraindication to replantation. These digits instead require a method to establish reliable drainage sufficient to allow for low resistance inflow and maintain a physiologic pressure gradient across capillary beds. The surgeon should select a decongestive technique that best suits the patient and their specific injury.

Abstract
BACKGROUND Digital replants and revascularization (DRV) have been performed since the 1960s but there are no recognized standard peri-operative anticoagulation practices. A narrative systematic review of the clinical effectiveness and safety of therapeutic peri-operative unfractionated heparin following DRV was undertaken. METHODS A review of the literature from 1985 to March 2022 was conducted using Medline, Embase, CINAHL and EBM reviews. Unfractionated heparin (UFH) use following DRV was compared to low-molecular weight heparin, other anticoagulants or no anticoagulation. Randomized trials, observational studies as well as guidelines were selected and independently screened. The Revised Cochrane risk-of-bias (RoB 2) tool and ROBINS-I were used to appraise risk of bias. RESULTS While the search strategy identified 1490 references, only six studies met the inclusion criteria. Significant heterogeneity and the low methodological quality of the evidence precluded a meta-analysis. Among the four studies that documented the surgical success rate associated with the use of a therapeutic dose of UFH post DRV, only two reported improved clinical outcomes. Evidence of a higher complication rate related to UFH use was found in four studies. Low quality evidence suggests that a therapeutic dose of unfractionated heparin leads to a higher risk of complications when compared with heparin given as an intermittent bolus of unfractionated heparin or subcutaneous heparin, or prostaglandin E1 or no heparin. CONCLUSIONS Current evidence suggests that IV UFH use following DRV has no significant impact on the success of the intervention. Heparin use may not be innocuous as some studies showed increased bleeding complications.

Abstract
Factors associated with failure of digital revascularization and replantation procedures have been well characterized, but studies have not investigated failures occurring beyond the early postoperative period. A single-centre retrospective chart review included 284 patients (434 digits) who underwent digital revascularization or replantation. Patient-, injury- and surgery-related characteristics were compared among successful procedures, digits that failed while in hospital (early failure), and initially viable digits that failed after hospital discharge (late failure). Overall, 202 patients had successful procedures (71%). There were 51 early failures (18%) and 31 late failures (11%). Crush injuries and vein grafting were associated with early failure only. Complete amputations and leeching were strongly associated with both early and late failure. This study revealed that a substantial proportion of initially viable digits fail after discharge from hospital. Patients with signs of venous congestion may benefit from longer observation periods in hospital to avoid late failure.Level of evidence: IV.

Abstract
BACKGROUND Replantation of amputated digits at the nail bed level is surgically challenging and differs from replantation at a more proximal amputation level. This study aimed to determine the predictors influencing the success rate of fingertip replantation. METHODS Overall, 239 digits of 226 patients who underwent replantation surgery from August of 2009 to March of 2020 were considered. A total of 15 independent variables (i.e., sex; age; injured hand; digit; history of smoking; history of hypertension or diabetes; injury mechanism; amputation level; ischemia duration; surgeon's expertise; numbers of repaired arteries, veins, and nerves; and the need for a vein graft) were investigated for their effects on the survival of the replanted digits. RESULTS Of all 239 digits, 190 (79.5 percent) survived. Univariate analysis indicated that non-crush-avulsion injury, expertise and experience of the surgeon, vein repair, and nerve repair contributed to increasing the survival rate. Binary logistic regression analysis demonstrated that injury mechanism, vein repair, and nerve repair were significant predictive factors. In addition, in non-vein-repaired, blunt cut, or Ishikawa subzone II cases, digital nerve repair contributed significantly to promote the success rate relative to vein-repaired, crush-avulsion-type injury, and subzone I cases. CONCLUSIONS Vein repair, nerve repair, non-crush-avulsion injury, and surgeon's expertise and experience were the predictors for successful replantation. Intraoperative vein and nerve repair are recommended to improve the survival rate of fingertip replantation at the nail bed level. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
BACKGROUND Fingertip replantation is technically challenging. Venous congestion is one of the most common causes of replantation failure. Therefore, various venous drainage procedures and salvage techniques have been used in venous congestion. Negative-pressure wound therapy has proven beneficial in limb injuries, yet limited studies of fingertip replantation exist. This study aims to analyze risk factors in fingertip replantation and to evaluate the feasibility and clinical benefits of negative-pressure wound therapy compared with other salvage techniques. METHODS From January of 2015 to December of 2019, 27 patients (27 digits) who experienced fingertip amputation over Tamai zone I or II underwent replantation. Salvage negative-pressure wound therapy was applied for venous congestion postoperatively. Replantation data were collected for further analysis. RESULTS The overall survival rate of digit replantation with salvage negative-pressure wound therapy was 92.6 percent (25 of 27). The blood transfusion rate was 11.1 percent (three of 27). The average hospitalization time was 8.04 ± 1.43 days and the median duration of negative-pressure wound therapy was 6 days (range, 4 to 8 days; interquartile range, 2 days). There is no significant difference between the survival and failure groups for all risk factors evaluated. CONCLUSION Negative-pressure wound therapy is a simple and effective salvage option to relieve venous congestion in fingertip replantation with a satisfactory survival rate, low blood transfusion rate, and short inpatient stay.

Abstract
PURPOSE Digit replantation is a high-stakes procedure that has been shown to be cost-effective, especially for multiple-digit replantation. However, it is associated with prolonged lengths of stay (LOS) for monitoring and attempts at salvage. The cost-effectiveness of prolonged inpatient stays presumes that this is necessary and inherent to the replantation. We hypothesized that prolonged monitoring of replanted digits, in the hope of possible salvage after primary failure, is cost-ineffective due to the low rates of vascular compromise and salvage after replantation. METHODS Using previously published data comparing quality adjusted life years lost after traumatic digit amputation versus digit replantation, we devised a cost utility model to evaluate the incremental cost-effectiveness ratio of inpatient monitoring. To determine rates of vascular compromise and salvage after digit replantation, we performed a systematic review of the literature through MEDLINE and SCOPUS database searches to identify relevant articles on digital replantation since 1990. Cost-effectiveness was stratified based on the number of digits replanted. RESULTS Fewer than 9% of replanted digits both experience vascular compromise and are successfully salvaged. Adjusting for this, inpatient monitoring for single-digit and thumb replantation becomes cost-ineffective after 1 day of admission and monitoring for multiple-digit replantation becomes cost-ineffective after 2 days of admission. CONCLUSIONS In the United States, prolonged admissions for inpatient monitoring quickly become cost-ineffective, especially with relatively low rates of salvage. Surgeons should avoid extended hospitalizations for replant monitoring and should pursue enhanced recovery protocols for replantation, especially considering burgeoning health care costs in the United States.

Abstract
Background Digital replantation is associated with a substantial risk of failure. There is considerable variation in survival rates globally, and the current data are limited by poor statistical methods and bias of selection, which limits its translation to Europe and the USA. We aimed to establish a more representative survival rate of digit replantation for western populations and evaluate espoused prognostic variables using robust statistical methodology. Materials and Methods Retrospective data were collected from 58 consecutive patients who underwent digital replantation following traumatic amputation in three tertiary care hand centres in the UK over seven years. The unit of analysis was the digit. Generalized linear modelling was used to estimate the odds ratio (OR) of digit survival. Results Forty-six of 68 replanted digits survived (68%). The typical replant candidate was a 40-year-old male manual worker. Digit survival was more likely with guillotine injuries (adjusted OR 25.5 [95% CI 5.60, 115]) and when intraoperative skeletal shortening was performed (adjusted OR 15.3 [95% CI 2.62, 89.5]). The age of the patient, seniority of the operating surgeon, and use of vein grafts was not associated with digit survival. Conclusion We provide robust data to show that guillotine amputations have more favourable survival rates, which can be further improved by skeletal shortening at the time of replantation. We suggest that research networks worldwide set up digit amputation registries to capture individual patient data on this uncommon injury.

Abstract
BACKGROUND Successful replantation relies on proper preservation of traumatically amputated parts. The established protocol for preservation, however, is inconsistently adhered to. The objective of this study is to examine the rate of proper preservation in multiple patient populations. METHODS A retrospective review of patients from 2015 to 2019 at a single academic institution was conducted. Patients were included if they suffered a traumatic amputation, the amputated part was present for evaluation by the hand surgery team, and modality of preservation was documented. Additional data including method of patient transport, replantation attempt, and operative outcome were assessed. Patients were stratified based on whether proper preservation was employed and compared using chi-square tests. RESULTS Ninety-one patients were included, thirty-one (34.1%) of whom had amputated parts which were properly preserved. Patients from referring facilities were more likely to present with properly preserved parts (45.0%) than those presenting from home (25.5%), though this did not meet significance (P = .051). In total, 74 patients arrived via EMS with 35.1% adherence to preservation protocol. Of the 31 patients who had properly preserved parts, 58.1% underwent attempted replant; of the 60 patients who had improperly preserved parts, 23.3% underwent attempted replantation (P = .001). CONCLUSIONS The majority of patients who suffer traumatic amputations do not present with properly preserved amputated parts, limiting potential replantation. With a direct correlation to attempted replantation, proper preservation is a crucial aspect of care and should not be overlooked when seeking to optimize efforts and results.

Abstract
Reconstructive microsurgery has been an essential aspect of orthopaedic surgery and extremity reconstruction since the introduction of the operating microscope in the mid-20th century. The reconstructive ladder ranges from simple healing by secondary intention to complex procedures such as free tissue transfer and vascularized composite allotransplantation. As orthopaedic surgery has evolved over the past 60 years, so too have the reconstructive microsurgical skills that are often needed to address common orthopaedic surgery problems. In this article, we will discuss a variety of complex orthopaedic surgery scenarios ranging from trauma to infection to tumor resection as well as the spectrum of microsurgical solutions that can aid in their management.

Abstract
Objective
To describe and compare the results obtained with a secondary healing protocol for fingertip amputations and their relationship to injury severity according to the Allen classification.
Methods
Medical records of 127 fingertip injuries were revised, and a retrospective, comparative, analytical study the amputations treated conservatively was performed. Injury characteristics, healing time, and complications were described and analyzed.
Results
Between April 2017 and May 2019, 127 fingertip injuries were treated conservatively. The average age of the sample was of 28.33 years. The average healing time was of 4.31 weeks. The complications during the follow-up were observed in 18.9% (
n
= 24) of the cases, but none require revision treatment. A statistically significant relationship between the development of complications and treatment revision according to the Allen classification was not found (
p
≥ 0.05).
Conclusion
The proposed secondary healing protocol has shown to be safe and effective in types 1 to 3 fingertip amputations in the Allen classification, and it should be included as a therapeutic option even in injuries of greater extension than those that have traditionally been limited to.

Abstract
BACKGROUND With the development of microsurgical techniques, the replantation survival rate has increased, but in some cases, revision surgery is required. Although there are many studies on replantation survival rate, studies on revision surgery are limited. In this study, we evaluated replantation patients requiring revision surgery in terms of amputation level, injury type, and amputation type (single-multiple). METHODS This is a retrospective study.Two hundred fifty-six patients (296 fingers) who were operated on for total finger amputation in our hospital between 2013 and 2018 were included in the study. In the postoperative period, revision surgery was required for 24 fingers due to vascular insufficiency. Patients were evaluated in terms of amputation level, injury type, and amputation type. RESULTS Two hundred sixty-four fingers were saved after primary surgery. Eight fingers failed before they could undergo revision surgery. Revision surgery was performed for 24 fingers. After revision surgery, 19 fingers were saved, and five fingers were failed. There was no significant effect of gender and age in terms of revision (p > 0.05).There was no statistically significant difference in injury level and injury type, but there was a statistically significant difference in terms of amputation type (p < 0.05). CONCLUSION Despite advanced microsurgery and experience, vascular insufficiency can be observed after replantation. Surgical re-exploration is necessary for salvage.

Abstract
PURPOSE This retrospective study analyses the effect performing veins anastomoses before arteries anastomoses in digital replantation. PATIENTS AND METHODS 38 adult patients with replantation of 12 thumbs and 39 fingers, in whom the veins anastomoses were performed prior to the arteries anastomoses, were compared with 29 patients with replantation of 9 thumbs and 30 fingers, in whom the arteries anastomoses were done first, with respect to the survival rate, total active motion, grip strength, and duration of the replantation. RESULTS There was no significant difference between the two groups with respect to the survival rates, total active motion, and grip strength, while the duration of the replantation was significantly shorter in patients, in whom the veins anastomoses were performed prior to the arteries anastomoses (2 hours and 50 minutes versus 3 hours and 42 minutes; p < 0.001). CONCLUSION Performing veins anastomoses before arteries anastomoses in digital replantations reduces the replantation time significantly without influencing the survival rate and the clinical outcome.

Abstract
Recently, a decellularized microvascular graft (inner diameter: 0.6 mm) modified with the integrin α4β1 ligand, REDV, was developed to provide an alternative to autologous-vein grafting in reconstructive microsurgery, showing good early-stage patency under arterial flow in rats. This consecutive study evaluated its potential utility not only as an arterial substitute, but also as a venous substitute, using a rat-tail replantation model. Graft remodeling depending on hemodynamic status was also investigated. ACI rat tail arteries were decellularized via ultra-high-hydrostatic pressure treatment and modified with REDV to induce antithrombogenic interfaces and promote endothelialization after implantation. Grafts were implanted into the tail artery and vein to re-establish blood circulation in amputated Lewis rat tails (n = 12). The primary endpoint was the survival of replants. Secondary endpoints were graft patency, remodeling, and regeneration for 6 months. In all but three cases with technical errors or postoperative self-mutilation, tails survived without any evidence of ischemia or congestion. Six-month Kaplan-Meier patency was 100% for tail-artery implanted grafts and 62% for tail-vein implanted grafts. At 6 months, the neo-tunica media (thickness: 95.0 μm in tail-artery implanted grafts, 9.3 μm in tail-vein implanted grafts) was regenerated inside the neo-intima. In conclusion, the microvascular grafts functioned well both as arterial and venous paths of replanted-rat tails, with different remodeling under arterial and venous conditions.

Abstract
BACKGROUND The competence of nurses who care for patients with finger replantation is critical for positive patient outcomes. This study sought to identify the effects of standardized patient (SP)-based training on surgical ward nurses' knowledge, clinical performance, and self-efficacy regarding finger replantation. METHOD A wait-list control group with a crossover design was used for this study. Nurses were randomly assigned to group A (n = 10) or to the wait-list control group B (n = 10). Training consisted of a lecture, task training, and SP-based training. Knowledge, clinical performance, and self-efficacy data were collected at baseline, after the first intervention, and after 1 month at group crossover and second intervention. Data were analyzed using repeated measures ANOVA. RESULTS Nurses demonstrated greater knowledge, better clinical performance, and higher self-efficacy scores after the SP-based training. Following crossover, knowledge, clinical performance, and self-efficacy scores were retained 1 month after the training in group A. CONCLUSION SP-based training produced improvement and retention in knowledge, clinical performance, and self-efficacy. [J Contin Educ Nurs. 2020;51(4):189-196.].

Abstract
BACKGROUND RESULTS Results of replantation surgery of replantation surgery following upper extremity traumatic amputation are extensively described in the literature, with success rates varying from 57 to 100 percent. The purpose of this study was to evaluate replantation success rate at a Level I trauma center over a 17-year period and to assess definable factors contributing to these results. METHODS A retrospective review of all digit and hand replantations at a Level I trauma center was performed using CPT codes from 2001 through 2018. Descriptive analyses, Mann-Whitney test, Kruskal-Wallis test, and logistic regressions were used. Significance was defined as p ≤ 0.05. RESULTS Analysis consisted of 76 patients with 101 amputated parts (93 digits and eight hands). Fifty-six single digit amputations (30 percent success rate), 37 multidigit injuries (22 percent digit success rate), and eight hand amputations (50 percent success rate) were attempted. The overall success rate was 25 of 76 patients (33 percent) and 29 of 101 parts (29 percent). The most common mechanism of injury was laceration (n = 56), followed by crush (n = 30), and avulsion (n = 11), with repair of laceration-type injuries having the greatest success rate (36 percent). CONCLUSIONS The authors report a lower success rate of hand and digit replantation than previously described in the literature. Whole hand and thumb replantations resulted in the highest survival rate in our series. Laceration mechanism showed a higher success rate than crush or avulsion-type injuries. The authors' modest results highlight the importance of effective internal auditing of low-volume replantation centers such as their own. Quality improvement measures are proposed for higher future success in replantation surgery at the authors' institution. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
The objective of this work was to assess whether the injury mechanisms are responsible for histological arterial lesions. This prospective single-center study included adults with wrist or hand arterial injury. Arterial resection of at least 2 mm from the proximal and distal stumps was performed before the arterial anastomosis. Histological analysis of the arterial stumps was performed. An ultrasound was performed 1 month postoperatively to check arterial patency. A clinical and functional evaluation was done at 1 month postoperative, then every 3 months. From 2018 to 2020, 46 patients were included with a maximum follow-up of 13 months. There were 35 cuts, 2 crush injuries, 8 amputation and 1 blast injury. Macroscopically, 37% of the margins were considered damaged. Histological analysis showed significant damage in 59% of the sections (27 out of 46 patients) with 50% for crush injury, 55% for cuts by mechanical tool, 62% for cuts by power tool, 62% for amputations and 100% for blasts. The failure rate was 9%: 2 replantations and 2 asymptomatic thromboses diagnosed by ultrasound. Postoperative pain on VAS was 1.75/10, range of motion was 87%, Quick DASH was 8%, SF36 PCS was 69% and SF36 MCS was 70%. Factors influencing the success or failure of anastomosis were the mechanism of injury (p = 0.02), associated nerve damage (p = 0.014) and length of proximal arterial cut (p = 0.046). Histological arterial lesions seem to correlate with the injury mechanism. Cuts caused by glass or crush injuries do not seem to require arterial resections of more than 2 mm. A continuation of the study with a larger number of subjects may generate statistically significant results.

Abstract
PURPOSE Venous anastomosis is the key procedure for Ishikawa zone Ⅱ fingertip replantation. Both palmar and lateral veins provide efficient venous drainage. This study compared the clinical effects between these venous anastomoses for fingertip replantation. METHODS In 2016-2018, 61 patients underwent Ishikawa zone Ⅱ fingertip replantation with venous anastomosis (28 and 33 cases with palmar and lateral anastomoses, respectively). Retrospective comparative analyses evaluated surgical technique and function, including operative time; rates of finger survival, venous congestion, and infection; sensation; joint motion; cold intolerance symptom severity (CISS), Disabilities of the Arm, Shoulder, and Hand (DASH), and Vancouver scar scores; and chronic regional pain syndrome (CRPS) rates. RESULTS There were 33 patients with lateral vein anastomosis and 28 patients with palmar vein anastomosis. The average patient follow-up was 18.2 months. The survival rates did not differ significantly between groups (87.8% (29/33) vs. 85.7% (24/28), p > 0.05); however, the operative time was shorter in the lateral vein group than in the palmar vein group (78.57 ± 7.08 min vs. 67.88 ± 5.77 min, p < 0.05). Venous congestion and infection rates did not differ significantly between groups (p > 0.05). The replanted finger function, including joint motion, sensation, DASH scores, Vancouver scar scores, and CRPS rates, did not differ significantly between groups (p > 0.05). However, the CISS score was higher in the palmar vein group than in the lateral vein group (44.39 ± 5.16 vs. 38.09 ± 4.49, p < 0.05). CONCLUSIONS Venous anastomosis with either palmar or lateral veins showed high survival rates and good function in fingertip replantation. The lateral vein had a shorter operative time and benefit to arterial revision and was especially suitable for patients with finger pulp damage.

Comparing digital replantation versus revision amputation patient reported outcomes for traumatic digital amputations of the hand: A systematic review and meta-analysis. Microsurgery 2021; 41:488-497. [PMID: 33811398 DOI: 10.1002/micr.30738] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 03/19/2021] [Accepted: 03/26/2021] [Indexed: 11/06/2022]
Abstract
PURPOSE Adults with traumatic digital amputation (TDA) of the hand may be managed with replantation or revision amputation. To date, there is no systematic review evaluating patient reported outcomes (PROs) comparing replantation versus revision amputation. METHODS Three databases (MEDLINE, EMBASE, and PubMed) were systematically searched in duplicate from inception until June 13, 2019 using Covidence software. Studies comparing replantation versus revision amputation outcomes were considered for inclusion. Methodological quality was assessed using Methodologic Index for Nonrandomized Studies (MINORS) criteria. Data were pooled in a random-effects meta-analysis model using Revman software. Certainty of evidence was evaluated using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). RESULTS Of 4350 studies identified, 12 retrospective cohort studies met inclusion criteria and compared TDA outcomes for replantation (n = 717; 82.9% male; mean age 40.3) versus revision amputation (n = 1046; 79.8% male; mean age 41.7). The overall replantation survival rate was 85.3%. The average MINORS score was 57% (13.75/24). Replantation of the thumb had a superior Michigan Hand Questionnaire (MHQ) score (+11.88, 95% CI [7.78-15.99], I2 = 21%) compared with revision amputation. Replantation of single non-thumb digits had a superior MHQ score (+5.31, 95% CI [3.10-7.51], I2 = 67%) and Disability of Arm, Shoulder, and Hand (DASH) score (-5.16, 95% CI [-8.27 to -2.06], I2 = 0%) compared with revision amputation. Most patients in the meta-analysis were from Asian populations (87.9%). CONCLUSION There is low-quality evidence that thumb replantation achieves superior PROs compared with revision amputation, which may be clinically important. Replantation of single non-thumb digits also yielded superior PROs, which is likely not clinically important and based on very low-quality evidence. Future studies with populations outside Asia are required to determine if PROs vary based on cultural differences toward digital amputation.
