Application of Artificial Dermis Combined With a Medial Flap From the Second Toe to Repair Degloving Injury of the Fingertip.

There is no standard technique for repairing degloving injuries of the fingertip. Nail bed flap transplantation is a common surgical technique to address this injury, but this procedure inevitably damages the donor site in the toe. This article describes a surgical technique that can restore the appearance of the injured fingernail and preserve the length and function of the injured finger without damaging the toenail.

Honey dressing for penile skin avulsion caused by traditional circumcision: a case report.

OBJECTIVE: Penile skin avulsion is a rare complication of circumcision but commonly encountered as the result of traditional practice. We aimed to present the use of honey dressing and the benefit of its wound healing properties for management of such a complex wound. CASE: A 24-year-old male patient with penile bleeding presented to the emergency department after undergoing traditional circumcision. Complete degloving of the penis with active bleeding and foul odour, along with heavy contamination of chewed betel leaves and powdered amoxicillin was found. Honey (Madu Nusantara, PT. Madu Nusantara, Indonesia) was used as dressing after copious irrigation using saline and povidone-iodine with bleeding control. RESULTS: Honey dressing was shown to be effective for secondary wound healing of such a complicated and contaminated wound-in this case due to its antimicrobial, anti-inflammatory, immunostimulatory and autolytic debridement properties. A complete re-epithelialisation of the wound was achieved without progression to the hard-to-heal state by day 43. Suboptimal sexual function and aesthetic result due to wound contracture were observed as surgical reconstruction via split-thickness skin graft was refused due to cost. CONCLUSION: In this case report, honey dressing was shown to be effective for wound healing, even in a penile avulsion with complete skin loss and heavy contamination. In rural settings, where penile avulsion due to traditional circumcision is common, honey should be considered as one of the dressing choices.

Integra® Dermal Regeneration Template as an alternative technique to treat degloving injury of fingers.

Soft tissue covering of degloving injuries of fingers remains a common challenge in trauma. In this case, we report the good long-term results after the use of Integra® Dermal Regeneration Template in combination with a split-thickness skin graft as an alternative treatment option for a patient with a traumatic degloving injury of multiple fingers.

Innervated Reconstruction of Fingertip Degloving Injury Using a Dorsal Digital Perforator Flap Combined With a Cross-Finger Flap.

BACKGROUND: The reconstruction of a fingertip degloving injury presents a functional and aesthetic challenge. We used a dorsal digital perforator flap combined with a cross-finger flap to reconstruct this type of injury. The purposes of this retrospective study were to evaluate the efficacy of the combined flaps and to present our clinical experience. METHODS: From November 2016 to October 2019, 16 patients (13 men and 3 women) with fingertip degloving injuries were treated with a dorsal digital perforator flap combined with a cross-finger flap for innervated reconstruction. We used an innervated dorsal digital perforator flap for the reconstruction of the dorsal defect of the degloved fingertip and an innervated cross-finger flap for the volar defect. The average size of the defect was 4.2 × 1.9 cm. The average sizes of the flaps were 2.3 × 2.1 cm (the dorsal digital perforator flap) and 2.5 × 2.1 cm (the cross-finger flap). RESULTS: All flaps and skin grafts survived completely without ischemia or venous congestion. All wounds and their donor sites healed primarily without exudation and infection. Patients were followed up for a mean time of 11.3 ± 1.9 months (range, 9-15 months). At the final follow-up, no significant difference was seen in the averaged total active motion between the injured fingers and the contralateral fingers. No significant difference was found in the averaged total active motion between the donor fingers and the contralateral fingers. All flaps obtained excellent or good sensory performance. All flaps had mild cold intolerance. Thirteen patients had no pain, 2 reported mild pain, and 1 experienced moderate pain. Ten patients were very satisfied with the appearance of the reconstructed finger. CONCLUSIONS: The dorsal digital perforator flap combined with a cross-finger flap is an effective and reliable method for the reconstruction of fingertip degloving injuries.

The triple conjoined scapular-latissimus dorsi-groin flap for reconstruction of long lower extremity degloving injury: A case report.

Since the introduction of the angiosome concept, many attempts have been made to push the dimensional limits of free tissue transfers. While initially limited by the boundaries of random vascularization of adjacent angiosomes, wider flaps were transferred by combining contiguous source vessels. Combined flaps, either chimeric or conjoined, represent nowadays the largest reconstructive options in the human body. This is the first report of a triple conjoined free flap with two vascular anastomoses, able to cover the anterior surface of the entire lower limb, representing the longest flap ever reported in history. A 43-year-old woman sustained a car accident as a pedestrian and presented with a massive circumferential degloving injury of the right lower limb. Femoral displaced shaft fracture and Gustilo type IIIb tibial fracture were diagnosed with emergent CT scan. A myocutaneous latissimus dorsi flap was planned, conjoined with the scapular flap to obtain a thick and large cover for the knee, and with a groin flap, to cover for the foot. Descending branch of lateral circumflex femoral artery and anterior tibial artery at the dorsum of the foot were selected as recipient vessels. Donor site was closed primarily. All flaps survived and no immediate nor late complications were reported. Follow up was 3 months. The triple conjoined flap can be considered a safe and useful reconstructive tool in severe degloving injuries of the lower limb, allowing the coverage of a large surface of the lesion with a single operation and without increasing the donor site morbidity.

Combined use of progressive tension suture and negative pressure wound therapy in large torso degloving wounds.

OBJECTIVE: To demonstrate the associated use of progressive tension sutures (PTS) with negative pressure wound therapy (NPWT) in large torso degloving wounds. METHODS: This is a case report of two patients with large torso degloving wounds caused by trauma, both of whom were treated with combined PTS and NPWT. Statistics related to wound treatment responses are presented. RESULTS: Initial wound area for Patient 1 was 2400cm2 and 900cm2 for Patient 2. Within 21 and 12 days, respectively, using the combined method, the following data were observed: wound reduction of 94% and 99%, respectively; a closing speed rate of 98cm2/day and 75cm2/day, respectively; and a closing percentage of 4.45% per day and 8.25% per day, respectively. CONCLUSION: The use of combined PTS and NPWT techniques may be useful in the treatment of traumatic degloving injuries, reducing the wound area and facilitating reconstruction.

The use of a caudal auricular axial pattern flap for repair of a degloving pinna wound in a dog.

A 3-year-old male neutered French bulldog was presented for an anatomical degloving injury of the left pinna following a conflict with a larger dog at a park. Approximately 2/3 of the dorsal skin was removed from the convex surface of the left pinna along with an irregular, full thickness injury on the lateral aspect of the pinna distal to the cutaneous marginal pouch. A caudal auricular axial pattern flap (CAAPF) was used to reconstruct the pinna. The flap healed with no noted necrosis over the long-term. Postoperative cellulitis was noted for approximately 3 mo. The dog was medically managed for bilateral otitis externa multiple times over the course of recovery. Long-term function and cosmesis at 1.5 y after surgery revealed adequate functional movement of the pinna and acceptable cosmesis. It is concluded that, rather than a pinnectomy, a CAAPF can be offered as a surgical option in dogs that have injuries localized to the pinna. Key clinical message: A CAAPF is an alternative to pinnectomy for reconstruction of the pinna after degloving injury and yields a functional and cosmetically acceptable outcome.

Utilisation d'un lambeau auriculaire caudal axial pour la réparation d'une plaie de dégantage du pavillon de l'oreille chez un chien. Un bouledogue français mâle castré âgé de 3 ans a été présenté pour une blessure anatomique par dégantage du pavillon gauche suite à un conflit avec un chien plus gros dans un parc. Environ les 2/3 de la peau dorsale ont été retirés de la surface convexe du pavillon gauche avec une lésion irrégulière de pleine épaisseur sur la face latérale du pavillon distal par rapport à la poche cutanée marginale. Un lambeau auriculaire caudal axial (CAAPF) a été utilisé pour reconstruire le pavillon. Le lambeau a cicatrisé sans nécrose notée à long terme. Une cellulite postopératoire a été notée pendant environ 3 mois. Le chien a été pris en charge médicalement pour une otite externe bilatérale à plusieurs reprises au cours de sa convalescence. La fonction à long terme et l'esthétique à 1,5 ans après la chirurgie ont révélé un mouvement fonctionnel adéquat du pavillon de l'oreille et une esthétique acceptable. Il est conclu que, plutôt qu'une pinnectomie, un CAAPF peut être proposé comme option chirurgicale chez les chiens qui ont des blessures localisées au pavillon.Message clinique clé :Un CAAPF est une alternative à la pinnectomie pour la reconstruction du pavillon après une blessure par dégantage et donne un résultat fonctionnel et esthétiquement acceptable.(Traduit par Dr Serge Messier).

Clinical decision model for the reconstruction of 175 cases of scalp avulsion/defect.

PURPOSE: It has been reported widely on various methods of repairing scalp avulsion/defect, including anastomotic vessels for total scalp avulsion and dermal grafts (skin grafting, latissimus dorsi or anterior serratus flap, "visor flap" repair.). The long-term retrospective study, however, with large sample size remains rare; and there is no report on decision-making tree for repairing emergency scalp avulsion/defects under critical conditions. METHODS: The decision-making model is provided for surgeons to design the scalp reconstruction based on the retrospective analysis of 175 cases of scalp avulsion/scalp defect. In this 10-year retrospective study, 175 cases of the repair of scalp avulsion and scalp defects in a single center were analyzed. The clinical decision model was generated based on representative cases. RESULTS: For patients with scalp avulsion/defects, a comprehensive examination and evaluation on systemic injury and complication should be conducted first for saving lives and reducing trauma effects. To make more reasonable clinical decisions, it is also required to determine the location, size, depth of scalp defect the injury area of cranial periosteum, injury of blood vessel or other adjacent organs, and whether the scalp can be reused. Meanwhile, it is necessary to evaluate whether the patient can tolerate long-term anastomotic vascular surgery according to the vital signs and physical status. CONCLUSION: The primary treatment goal is to decrease traumatic effects and save patient's life while repairing and reconstructing scalp avulsions and scalp defects. In addition, it is necessary to comprehensively consider the anatomical, functional and cosmetic characteristics of scalp, surgical equipment, team technical skillsets and patient's own pursuit to optimize a reasonable surgical solution.

Revascularization of a Circumferential Hand and Forearm Degloving Injury Using an Arteriovenous Shunt.

Major upper-extremity degloving injuries with distal dysvascularity are rare and challenging surgical problems. When these degloving injuries occur over nonexpendable regions, such as the glabrous skin of the palm and digits, revascularization or replantation may be the treatment of choice. Because the degloved skin flap is often separated in the suprafascial plane, direct arterial repair may be impossible. We present a rare case of circumferential degloving of the hand and forearm with distal dysvascularity, treated successfully with revascularization with arterial anastomosis, venous anastomosis, and arteriovenous shunt creation. The patient required reoperation for partial flap loss and ligation of the arteriovenous fistula. At final follow-up 16 months after the injuries, she showed independence in activities, reported good functional use of the hand, and worked full-time at her original occupation.

Reconstruction of a Large Traumatic Medial Cheek Defect Using an Anterior-Based Subcutaneous Cervicofacial Rotation Advancement Flap.

In this article, we describe reconstruction of a large left-side medial cheek defect in a 78-year-old woman using a cervicofacial rotation advancement flap. To our knowledge, this is the second case of reconstruction of a large traumatic medial cheek defect using an anterior-based subcutaneous cervicofacial rotation advancement flap that has ever been reported. We applied retention sutures at the level of the jawline and zygomatic eminence using 3-0 nonabsorbable sutures between the subcutaneous tissue of the flap and the periosteum. Despite the limitation of having partially injured adjacent tissue available for reconstruction, meticulous dissection together with skilled postoperative nursing care yielded a good aesthetic outcome in this case.

BIO-NAIL: a bacterial cellulose dressing as a new alternative to preserve the nail bed after avulsion.

Avulsion of the nail plate is the most accomplished surgical procedure among the nail apparatus surgeries. Since it is not possible to use the removed nail to cover the nail bed, some materials have been suggested, however, they are generally not available for use and often at a high cost. To evaluate the use of Bacterial Cellulose (BC) dressing as a biological nail (Bio-Nail) after partial or total avulsion of the nail plate. Twenty-six candidates for nail avulsion, were randomized into two groups: Control, using Vaseline with gauze (11 patients) and Experimental group, BC group, using the Bio-Nail (15 patients). The patients were followed up during the 180-day period. The distribution of the patients in the groups was homogeneous for both sociodemographic and clinical data. The occurrence of infection (1 case in the control group) was not statistically relevant. The BC group had lower pain intensity (p = 0.011) with earlier temporal resolution when compared to the control group (p = 0.003). The BC group presented earlier reepithelization (p = 0.022) and better quantitative (p = 0.021) and qualitative conditions (p = 0.011) for the exudate. Regarding satisfaction, all the patients were satisfied. Good preservation of the nail plate area was observed in the BC group at the end of the 180-day period (p = 0.024). Average time of BC dressing permanence was 16.4 ± 7.1 days. BC showed to be appropriate as a dressing after partial or total avulsion of the nail plate. BC is a Bio-Nail promising for nail bed healing.

Revisión narrativa: ¿Laceraciones pretibiales, avulsiones o desgarros cutáneos?

Narrative review: skin tear, laceration or skin avulsion? The current definitions for skin tear, laceration and skin avulsion do not provide a clear and evident differentiation between them in clinical practice, as their descriptions vary from author to author. Most of the literature uses these terms to refer to lacerations, but in practice, they can also mean skin avulsions, skin tears and pretibial lacerations, creating confusion among health professionals. This narrative review aims to provide the authors' views to help reach a precise definition for such terms and avoid further confusion in clinical practice.

Sinopsis: Las definiciones actuales para los términos "desgarro cutáneo" (skin tear), "laceración" (laceration) y "avulsión cutánea" (skin avulsion) no permiten diferenciar estas heridas de manera clara y evidente, ya que su descripción semiológica adquiere variabilidad de nomenclatura dependiendo de cada autor, como se comprobó a través de la revisión de la literatura médica consultada. En la mayoría de los textos, los tres términos son usados indistintamente para referirse a laceraciones pero, en la práctica clínica, se suelen referir también a avulsiones cutáneas, heridas pretibiales, heridas en colgajo, y desgarros cutáneos, lo cual suele generar confusión. El objetivo de esta revisión narrativa es proveer una opinión de expertos para llegar a una descripción precisa de dichos términos y evitar, así, confusión en la práctica clínica.

Polytrauma from a North American Black Bear Attack.

Bear attacks, although rare, can inflict life-threatening injuries. We present the case of a 50-y-old woman from rural Pennsylvania who was attacked by a North American black bear, Ursus americanus. She sustained multiple complex injuries including near-complete scalp avulsion, bilateral ear avulsions, and fractures of the face, ribs, and pelvis. These injuries are similar to those sustained in other bear maulings reported in the literature and required both acute intervention and a multidisciplinary approach to recovery.

A peculiar case of Morel-Lavelle lesion of upper limb.

Morel-Lavallee lesions (MLL) are post-traumatic, closed internal degloving injuries that can result in severe complications if not diagnosed early. It is conventionally seen in cases of the high energy injuries of the pelvis and lower limb. The accumulation of extravasated blood, secondary to fracture and soft tissue damage may cause internal degloving injury, skin necrosis, soft tissue damage and acute osteomyelitis. We report here the clinical and radiological features in a 32-year-old male referred from the emergency department of a tertiary hospital who had sustained high energy motor vehicle accident. On examination, there was a fluctuant, mobile, non-tender subcutaneous mass over the distal arm with suspicion of internal degloving injury. Plain radiographs showed no fractures. Ultrasound showed a fluid collection with the presence of septations and echogenic debris within the collection. Extravasation was noted between subcutaneous tissue layer and fascia at the posterolateral aspect of the arm. Wound debridement under general anaesthesia was carried out. Intraoperative findings reported a significant amount of thick serous fluid with necrotic debris. Unhealthy skin and fat layers were debrided. Underlying muscles were found to be healthy. The results of the intraoperative fluid culture and sensitivity showed no growth. Negative pressure vacuum dressing was carried out. After five cycles of vacuum dressing, the wound showed signs of healing with an improved range of motion of the elbow. Orthopaedic surgeons need to be vigilant of the possibility of MLL in the upper limb as a differential diagnosis in the management of high energy trauma.

A Novel Muscle Transfer for Independent Digital Control of a Myoelectric Prosthesis: The Starfish Procedure.

Control of independent digital flexion and extension has remained an elusive goal in myoelectric prosthetics for upper extremity amputees. We first performed a cadaver study to determine the feasibility of transferring the interossei muscles for each digit to the dorsum of the hand without damaging the neurovascular pedicles. Once this capability was ensured, a clinical case was performed transferring the interossei of the middle and ring fingers to the dorsum of the hand where they could serve as a myoelectric signal for a partial hand amputee to allow individual digital control with a myoelectric prosthesis. Before surgery, it was impossible to detect an independent signal for each interossei; however, after the surgery, signals were reliably detected, which allowed these muscles to serve as myosites for finger flexion using a myoelectric prosthesis and move each digit independently. This concept of salvaging innervated and perfused muscles from an amputated part and transferring them into the more proximal and superficial portion of a salvaged limb has broad applications for improved myoelectric prosthetic control.

Post-traumatic lymphedema treatment with superficial circumflex iliac artery perforator lymphatic free flap: A case report.

Post-traumatic lymphedema is poorly understood. It is rarely considered in limb reconstruction decision-making approach. We report a case of a 41-year-old female who presented with right upper extremity lymphedema after degloving injury and split thickness skin graft, successfully treated with a superficial circumflex iliac artery perforator (SCIP) free flap restoring the lymphatic drainage. Right upper extremity had an excess of 258.7 mL or an excess volume of 27.86% compared to the healthy contralateral limb. A SCIP free flap including lymphatic vessels (SCIP-L) was performed to replace the skin graft in order to restore the lymphatic flow. Flap size was 19 × 8 cm and pedicle length was 4 cm. No lymph nodes were included and no lymphatic or lymphovenous anastomoses were performed. The surgery was uneventful, and there were no postoperative complications. Fourteen days after free tissue transfer, lymphedema showed clear improvement. At a 4-month follow-up, 55.6% reduction of excess volume was obtained. Indocyanine green lymphography performed at that time showed a restitution of lymph flow through the flap. Lymphedema improvements persisted at a 6-month follow-up. A successful treatment of post-traumatic lymphedema can be performed by using the SCIP-L free flap for soft tissue reconstruction of critical lymphatic drainage areas.

Preferred Experience of Modifications to Emergency Surgical Treatment for Total Scalp Avulsion With Halo-Vest Head Ring and Quick Hair Removing.

BACKGROUND: Total scalp avulsion is a fairly rear but severe soft tissue injury. Even with microsurgical replantation, the survival rate is still low. In this study, the authors incorporated 2 main modifications (Halo-Vest head ring and quick hair removing) and assessed the surgical outcomes versus those of traditional replantation. METHODS:: Eighteen patients were included in the study who suffered from total scalp avulsion. After consideration of the outcomes from the first 7 patients, the authors modified our surgical procedures and introduced the use of Halo-Vest head ring and quick hair removing in the treatments for the rest 11 patients. The surgical outcomes with both approaches were observed and compared, including the operation time and incidence of scalp necrosis. RESULTS:: The mean debridement time was 3.5 hours in traditional treatment versus 1.68 hours in modified treatment. The mean operative time was 11.14 hours in traditional treatment versus 8.05 hours in modified treatment. After the replantation, in those 7 patients without modifications, there was 1 total scalp necrosis and 6 partial scalp necrosis. In those 11 patients with modifications, there was 1 total scalp necrosis and 1 suffered a partial scalp necrosis, while the scalp survived well in other 9 patients. Classical cases with modified or traditional methods were reported respectively. CONCLUSION: The application of Halo-Vest head ring and quick hair removing provides a reliable method to treat total scalp avulsion. It is safe, technically easy and worth being widely used in the clinical application.

The management of degloving injuries of the limb with full thickness skin grafting using vacuum sealing drainage or traditional compression dressing: A comparative cohort study.

BACKGROUND: Degloving injuries of the limb are severe and frequently underrated. Few researches are available comparing the results of reattachment of the degloved skin grafts with the vacuum sealing drainage technique and the traditional compression dressing method. In this study, we aimed to compare the treatment outcomes of these two approaches. METHODS: Eighty-three consecutive patients were treated for degloving injury of the limb. Based on the treatment approach, the patients were divided into vacuum sealing drainage group (VSD group, n = 55) and traditional compression dressing group (TCD group, n = 28). After reattachment, the degloved skin was secured with stitches and compressed with VSD or TCD. The outcomes were mainly assessed based on the percentage of skin graft take. RESULT: In VSD group, there were excellent results in 18, fair in 9 and poor in 28, respectively; In TCD group, there were excellent results in 11, fair in 10 and poor in 7, respectively. Statistically, no significant difference was found between two groups in terms of the category of excellent results. However, significant higher incidence of poor results with necrotic areas exceeding 50% was observed in the VSD group than that in the TCD group. In addition, although the duration of hospitalization in the VSD group was shorter than that in the TCD group, the medical supply costs and total costs were much higher than that of the TCD group. CONCLUSION: VSD and TCD are equally effective in the management of degloving injuries of the limb; however, VSD technique may potentially have a higher risk of poor results with increased hospital charges. The traditional approach still has its merits in clinical practice, especially in rural hospitals when VSD is not available or unaffordable.

Deep hypothermic preservation of autologous skin in the treatment of large-area circumferential multi-plane degloving trauma: a pilot study of 2 cases.

To evaluate the clinical outcome of deep hypothermic preservation of autologous skin in the treatment of large-area skin avulsion. Medium or full thickness-skin slices were harvested from large avulsion flaps between July and November 2017. They were stored in liquid nitrogen by vitrification. After the patient's condition became stable and the growth of the wound granulation tissue was satisfactory, the frozen skin slices were reheated quickly and replanted to the wound. Autologous skin that had been kept by deep cryopreservation had a high survival rate when grafted. It did not create new trauma or bring additional pain to patients. Yet it could shorten the course of treatment and reduce the medical cost for patients. It is an effective and economical way to treat large-area skin avulsion.
