Management of Traumatic Nasal Avulsion Injuries.

Soft tissue injuries to the midface (and nose) are common causes for seeking trauma care. As trauma patients, observing advanced trauma life support protocols is warranted given the risk of concomitant injuries. Here, options for optimizing tissue preservation, microvascular replantation, non-microvascular tissue replacement, and wound stabilization are discussed. Included in this discussion are data-driven predictors for successful replantation as well as technique descriptions with anatomic references to guide surgeons in choosing optimal donor vessels. In both partial and complete avulsion injuries, venous congestion is common. Several postoperative wound care protocols to maximize tissue perfusion and long-term viability are discussed.

Advances in Pediatric Toe Transfers.

Microsurgery is undoubtedly the pinnacle of hand surgery. Significant advancement in recent years has stretched the indications for toe-to-hand transfer in both acquired and congenital hand defects to restore function, esthetics, and motion, with minimal morbidity to the donor site. There is no one fixed microsurgical transfer technique but a surgeon's versatility and innovation in using what one could spare because each case is unique. Esthetic refinements and reducing donor site morbidities have taken a front seat in recent years. We present a few cases to put forward the senior author's preferred techniques with this objective in mind.

The Foot as a Donor Site for Reconstruction in the Hand.

The foot contains a unique collection of tissue types that can be used in the reconstruction of the hand. Numerous reconstructive options have been presented, some of which have been adopted, such as modifications to procedures that have been described in the past or even newly developed options for hand reconstruction. It is possible to reconstruct missing fingers and other hand structures using tissues taken from the foot rather than removing healthy tissue from a hand that has already been injured. This makes it possible to avoid having healthy tissue removed from an injured hand.

Midlateral Approach Replantation of a Distal Phalanx Second Toe Amputation in a 4-Year-Old Child: A Case Report.

CASE: A 4-year-old girl patient presented with complete amputation of the second toe close to the distal interphalangeal joint. Replantation was performed using a novel midlateral approach. The procedure used the dorsal subcutaneous vein on the foot as a graft for the artery. Four months postoperatively, the toe healed without any complication. The patient reported pain-free physical exercise without limitations in daily activity. CONCLUSION: This report demonstrates that this approach has the potential to provide a safe and viable alternative for treating toe amputations and offers advantages such as simplified artery identification, straightforward anastomosis, and improved vein graft harvesting.

[Severe and complex traumatic hand]. / Main traumatique grave et complexe.

SEVERE AND COMPLEX TRAUMATIC HAND . Serious and complex traumatic injuries of the hand are multiple tissue injuries (skin, vascular, bone and nerves), requiring urgent surgical management. They are responsible for significant functional and aesthetic sequelae. Their incidence is clearly decreasing thanks to information, prevention and security measures. The absolute emergencies are injections under pressure, amputations-devascularizations, and serious mutilations. The objective of the management is to make a functional and aesthetic hand: restoration of the opposition of the thumb with a key-pinch, a sufficient length thumb, and restoration of the sensitivity of the reconstructed hand. This calls for numerous surgical and microsurgical techniques and must be undertaken by trained teams in specialized centers.

MAIN TRAUMATIQUE GRAVE ET COMPLEXE. Les lésions traumatiques graves et complexes de la main sont des lésions tissulaires multiples (cutanées, vasculaires, osseuses et nerveuses), nécessitant une prise en charge chirurgicale urgente. Elles sont responsables de séquelles fonctionnelles et esthétiques importantes. Leur incidence est en nette diminution grâce aux mesures d'information, de prévention et de sécurité. Les principales urgences absolues sont les injections sous pression, les amputations-dévascularisations et les mutilations graves. L'objectif de la prise en charge de ces traumatismes est de rendre une main fonctionnelle et esthétique : restauration d'opposition du pouce, d'un pouce de longueur suffisante, d'une pince pollici-digitale termino-latérale, rétablissement de la sensibilité de la main reconstruite. Ceci fait appel à de nombreuses techniques chirurgicales et microchirurgicales et doit être entrepris par des équipes entraînées en centres spécialisés.

Clinical outcomes of reposition flap transfer for fingertip amputation.

PURPOSE: This study aimed to describe the reposition flap for reconstructing fingertip amputation when replantation is not possible. METHODS: This study retrospectively reviewed the records of patients with reposition flap transfers and investigated postoperative clinical outcomes and patient satisfaction. Sixteen patients with fingertip amputations treated with a reposition flap from 2016 to 2020. The mean age at injury was 46 years (range, 26-70 years). Ten cases were treated with oblique triangular advancement flaps, 3 with retrograde-flow digital artery flaps, and 3 with thumb palmar advancement flaps. Postoperative outcomes, including wound healing period and the IP/PIP extension angle, and the presence of grafted bone absorption and patient satisfaction were evaluated as of 3 years after surgery. RESULTS: The average reduction in passive extension angle of the IP/PIP joint was 19°. The average time for complete wound healing was 28 days (range, 18-41 days). The reduction in passive extension angle of the IP/PIP joint was significantly correlated with the wound healing period (r = 0.66, p = 0.01). The absorption of the grafted bone was observed in 3 cases. In these cases, the distal tip of the flap became thin due to flap retraction and an insufficient flap volume. All patients were highly or fairly satisfied with the results of surgery. CONCLUSION: Our findings show that IP/PIP flexion contracture can occur due to delayed wound healing after reposition flap transfer, but the patient satisfaction level was generally high. Therefore, reconstruction using a reposition flap gives acceptable clinical outcomes and high patient satisfaction as a result of medium to long-term.

Distal fingertip replantation: indications, strategy and postoperative management.

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.

Patient satisfaction after lower limb replantation surgery for traumatic amputation - a qualitative study.

BACKGROUND: The majority of published literature clinically assesses surgical outcomes after lower limb replantation for traumatic amputations. However, patients' satisfaction and quality of life may not be accurately measured through rigid scoring using standardized patient reported outcome measures. PURPOSE: The aim of this study was to qualitatively assess patient satisfaction and factors associated with achieving good outcomes after successful lower limb replantation surgery. METHODS: A semi-structured interview was conducted with 12 patients who underwent lower limb replantation surgery following traumatic amputation injuries. The interview focused on the patients' experience and satisfaction throughout their injury, surgical journey, rehabilitation and reintegration into their communities. An inductive and deductive thematic analysis was applied using the recorded transcripts to evaluate the overall satisfaction of the patients after lower limb replantation surgery. RESULTS: The following observations emerged from the structured themes among all the patients interviewed: (1) Family and social support was significantly associated with improved qualities of life and satisfaction after lower limb replantation; (2) Patients were generally satisfied with their outcomes despite limitations in physical capabilities; (3) Satisfaction was associated with acceptance of their cosmetic deformity; (4) Social integration and being able to participate in a meaningful manner was associated with greater satisfaction after recovery. CONCLUSIONS: Patients who undergo lower limb replantation can have a significantly improved quality of life if they have strong social support, are able to contribute in a meaningful manner to their communities after surgery, and are accepting of their cosmetic deficiencies.

Concurrent validity study of QuickDASH with respect to DASH in patients with traumatic upper extremity amputation.

BACKGROUND: The Disability of the Arm, Shoulder and Hand Outcome Measure (DASH) is a validated patient-reported outcome measure (PROM) for many upper extremity musculoskeletal disorders. In patients with severe traumatic conditions, limited evidence exists regarding the equivalence between DASH and its shortened version, QuickDASH, which is more feasible in clinical practice. The rationale of this study was to analyze the concurrent validity of QuickDASH with respect to DASH in patients with traumatic upper extremity amputation. METHODS: This study is based on a consecutive cohort of traumatic upper extremity amputation patients treated with replantation or revision (completion) amputation at Tampere University Hospital between 2009 and 2019. We estimated the concurrent validity of QuickDASH with respect to DASH by correlation coefficients, mean score differences, Bland-Altman plots, and distribution density. Additionally, we assessed internal reliability with Cronbach's alpha coefficients and item-total correlations. RESULTS: We found a very strong linear correlation between DASH and QuickDASH scores (r = 0.97 [CI 95% 0.97-0.98], p < 0.001). The mean difference between DASH and QuickDASH was minor (MD = -1, SD 4 [CI95% from -1 to 0] p = 0.02). The mean sub-score for the activity domain was higher for QuickDASH than DASH (MD = -3 [CI95% from -4 to -3] p < 0.000) and lower for the symptom domain (MD = 7 [CI95% from 6 to 9] p < 0.000). The Bland and Altman plot showed good agreement between DASH and QuickDASH scores, but there was measurement error in QuickDASH with high scores (r = -0.20, [CI95% from -0.31 to -0.09], p = 0.001). CONCLUSION: QuickDASH demonstrates higher total scores than the full DASH and emphasizes rating of activity over symptoms. Still, on average the differences in total scores are likely less than the MCID of DASH, and consequently, this study shows that QuickDASH can be recommended instead of the full DASH when assessing a traumatic condition. TRIAL REGISTRATION: Retrospectively registered.

Fingertip Replantation: Surgical Technique, Tips, and Tricks.

SUMMARY: Replantation of fingertip amputations restores the original tissue and is the ideal treatment to provide the best aesthetic and functional outcome. However, successful fingertip replantation is considered challenging because it requires supermicrosurgery techniques. This article provides a detailed surgical technique for fingertip replantation and the authors' preferences and recommendations. In the authors' experience, the most important factors for successful fingertip replantation are meticulous vascular dissection, reliable arterial repair, and venous anastomosis to avoid postoperative venous congestion. Proximal arterial dissection until pulsatile bleeding is encountered avoids the zone of vascular injury, and is particularly important in crush or avulsion amputations. Distal arterial dissection is performed until undamaged intima is identified. The authors believe anastomosis to the central artery is reliable even in a Tamai zone II amputation. When an arterial defect is present, the authors recommend using a vein graft to anastomose to the central artery. In addition, the authors highly recommend at least one venous anastomosis to avoid postoperative venous congestion. In Tamai zone I, available veins can be found on the palmar side of the pulp. It is important to search directly below the dermis and remove adipose tissue around the vessels to secure space for anastomosis. The authors consider nerve suture in Tamai zone I and II replantations inessential, because spontaneous sensory recovery can be expected. Postoperative management of venous congestion, spasm in artery, and arterial thrombosis are as important as surgery.

Traumatic Transradial Forearm Amputation Temporized With Extracorporeal Membrane Oxygenation: A Brief Report.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is typically used to provide mechanical perfusion and gas exchange to critically ill patients with cardiopulmonary failure. We present a case of a traumatic high transradial amputation in which the amputated limb was placed on ECMO to allow for limb perfusion during bony fixation and preparations and coordination of orthopedic and vascular soft tissue reconstructions. MATERIALS AND METHODS: This is a descriptive single case report which underwent managment at a level 1 trauma center. Instutional review board (IRB) approval was obtained. RESULTS: This case highlights many important factors of limb salvage. First, complex limb salvage requires a well-organized, pre-planned multi-disciplinary approach to optimize patient outcomes. Second, advancements in trauma resuscitation and reconstructive techniques over the past 20 years have drastically expanded the ability of treating surgeons to preserve limbs that would have otherwise been indicated for amputation. Lastly, which will be the focus of further discussion, ECMO and EP have a role in the limb salvage algorithm to extend current timing limitations for ischemia, allow for multidisciplinary planning, and prevent reperfusion injury with increasing literature to support its use. CONCLUSIONS: ECMO is an emerging technology that may have clinical utility for traumatic amputations, limb salvage, and free flap cases. In particular, it may extend current limitations of ischemia time and reduce the incidence of ischemia reperfusion injury in proximal amputation, thus expanding the current indications for proximal limb replantation. It is clear that developing a multi-disciplinary limb salvage team with standardized treatment protocols is paramount to optimize patient outcomes and allows limb salvage to be pursued in increasingly complex cases.

The perfusion index as a noninvasive method for monitoring revascularized and replanted digits.

BACKGROUND: Monitoring replanted digits remains a challenging task in microsurgical units. Previous studies have indicated the perfusion index (PI), a parameter directly proportional to the blood flow, might be a useful tool. OBJECTIVE: The PI is evaluated as a monitoring tool in patients with replanted digits. METHODS: This prospective, non-interventional study includes 31 patients with revascularized or replanted digits. After successful revascularization or replantation, the PI and peripheral oxygen saturation of the affected finger and its contralateral equivalent were measured simultaneously. The values were detected by the device Radical-97® Pulse CO-Oximeter® (Masimo Corporation, 52 Discovery, Irvine, CA 92618, USA). RESULTS: The median PI of affected fingers was 3.5±0.56 for revascularized and 2.2±0.8 for replanted fingers. The difference between the PI values of replanted digits and the healthy contralateral side was highly significant (p < 0.0001). The area under the curve in the receiver operating characteristics was 0.92 for a PI difference > 80.49% and predicted a loss of replant with a specificity of 100% and a sensitivity of 75%. CONCLUSION: The assessment of the PI in patients with reperfusion of a vascular compromised digit is a useful tool to continuously monitor peripheral perfusion. The dynamic behavior of the PI is essential to detect perfusion disturbance.

Healthcare Utilization Following Hemipelvectomy or Hip Disarticulation in the Military Health System.

INTRODUCTION: Amputations at the hip and pelvic level are often performed secondary to high-energy trauma or pelvic neoplasms and are frequently associated with a prolonged postoperative rehabilitation course that involves a multitude of health care providers. The purpose of this study was to examine the health care utilization of patients with hip- and pelvic-level amputations that received care in the U.S. Military Health System. MATERIALS AND METHODS: We performed a retrospective review of all patients who underwent a hip- or pelvic-level amputation in the Military Health System between 2001 and 2017. We compiled and reviewed all inpatient and outpatient encounters during three time points: (1) 3 months pre-amputation to 1 day pre-amputation, (2) the day of amputation through 12 months post-amputation, and (3) 13-24 months post-amputation. Health care utilization was defined as the average number of encounter days/admissions for each patient. Concomitant diagnoses following amputation including post-traumatic stress disorder, traumatic brain injury, anxiety, depression, and chronic pain were also recorded. RESULTS: A total of 106 individuals with hip- and pelvic-level amputations were analyzed (69 unilateral hip disarticulation, 6 bilateral hip disarticulations, 27 unilateral hemipelvectomy, 2 bilateral hemipelvectomies, and 2 patients with a hemipelvectomy and contralateral hip disarticulation). Combat trauma contributed to 61.3% (n = 65) of all amputations. During the time period of 3 months pre-amputation, patients had an average of 3.8 encounter days. Following amputation, health care utilization increased in both the year following amputation and the time period of 13-24 months post-amputation, averaging 170.8 and 77.4 encounter days, respectively. Patients with trauma-related amputations averaged more total encounter days compared to patients with disease-related amputations in the time period of 12 months following amputation (203.8 vs.106.7, P < .001) and the time period of 13-24 months post-amputation (92.0 vs. 49.0, P = .005). PTSD (P = .02) and traumatic brain injuries (P < .001) were more common following combat-related amputations. CONCLUSIONS: This study highlights the increased health care resource demand following hip- and pelvic-level amputations in a military population, particularly for those patients who sustained combat-related trauma. Additionally, patients with combat-related amputations had significantly higher rates of concomitant PTSD and traumatic brain injury. Understanding the extensive needs of this unique patient population helps inform providers and policymakers on the requirements for providing high-quality care to combat casualties.

Free neurovascular toe-(joint)-transfers compared to alternative reconstructive procedures for amputation injuries of two and tripartite fingers with substance loss.

BACKGROUND: Complex injuries of the hand frequently result in loss of essential functional features. Common reconstructive procedures for soft tissue defects of the thumb or phalanges are locoregional flaps like Moberg-, Foucher-, Cross-Finger- or Littler flaps. Microneurovascular toe (joint-) transfers complete the arsenal of operative reconstructive procedures and allow for most detailed reconstructions. Our experiences with free toe transplants are reported and diversely discussed regarding contending procedures. METHODS: From 2010 until 2019 14 patients who received emergency or elective partial or complete toe transfers were compared with a control group (n = 12) treated with contending reconstructive procedures. Aim of the reconstructions was to cover the defect with well-vascularized, sensate tissue, while preserving length and range of motion in a reliable manner. RESULTS: The Kapandji score showed a significant difference (p- value = 0.04) with a score of 9.8 in comparison to control group (Kapandji index = 8.0). CONCLUSION: In our heterogenic patient collective free toe transplants have proven to achieve comparable functional results for reconstruction of two and tripartite phalanxes as opposed to common local reconstructive procedures.

A Prospective Study of Graft Repositioning over Flap Technique for Reconstruction of Fingertip Amputation.

Background: Replantation of digital tip amputations, especially Allen III and IV, is challenging for hand surgeons as it requires a high level of microsurgical expertise and fine instruments. The graft repositioning over flap (GRF) technique is a simple and reliable procedure that provides length, sensation and nail growth and GRF has become popular in the last few years. The aim of this study is to report the short-term outcomes of the GRF technique. Methods: This is a prospective study of all patients who underwent a GRF reconstruction for Allen III and IV digital amputations at our hospital over a 12-month period. In addition to demographic data and injury details, we collected outcomes data with regard to flap and nailbed graft survival, capillary refill time, nail growth, sensation (2-point discrimination), bone union and gain in length of digit compared to length at injury. Results: Twenty patients underwent GRF reconstruction of digital amputation. They included 18 men and 2 women with an average age of 29 years. The thumb was the most frequently injured digit (n = 7). Electric saws (n = 5) and industrial machines (n = 5) accounted for 50% of injuries. Twelve amputations were Allen IV. Five patients were lost to follow-up and outcomes data was available for 15 patients. There was loss of flap and nail bed in three patients. There was no growth of nail in three patients. The distal phalanx graft was lost in six patients and united in the remaining nine patients. Conclusions: The GRF technique is a simple and reliable option in patients in whom replantation is not possible. It restores length, provides sensation and nail growth in the reconstructed fingers. Level of Evidence: Level IV (Therapeutic).

Successful Pediatric Penile Replantation Following Amputation During Ritual Circumcision: A Case Report and Literature Review.

BACKGROUND Circumcision is commonly performed in males, especially in Jewish and Muslim cultures, and is considered a safe surgical procedure with a low complication rate. Major complications, such as partial and total penile amputation, can occur, but those are rare complications. However, high replantation success rates have been reported and reviewed. CASE REPORT We describe the case of an 8-year-old boy who experienced total penile amputation during ritual circumcision performed by a layperson outside the hospital setting. Microsurgical penile replantation was performed after an ischemic period of 16 hours 43 minutes, with successful outcomes and without any major complications. In our technique, we repaired both dorsal and deep cavernosal vessels. At 1-year postoperative period, the results of two-point discrimination test were 4 mm, 7 mm, and 7 mm on the dorsal part, ventral part, and glans, respectively. After a follow-up period of 4 years, there were no late complications such as penile deformity, urethral fistula, urethral stenosis, absence of penile sensation, or erectile dysfunction. The results of two-point discrimination test were 3 mm, 5 mm, and 5 mm on the dorsal part, ventral part, and glans, respectively. The patient also experienced good penile sensation, morning erection, satisfaction with the cosmetic outcome, and a peak urine flow rate of 21 mL/s with a consistently strong void stream and a low postvoid residual urine volume of 20 mL. CONCLUSIONS Our experience suggests that a short ischemic time, prompt surgical correction, microscopic technique of replantation, and intensive postoperative care can result in good functional outcomes.
