RESUMO
PRACTICAL RELEVANCE: Axillary wounds most often occur in outdoor cats that wear a collar, typically after having been missing. These wounds are commonly chronic and indolent in nature, and although there is so far no consensus on an explanation for this, it is likely that there are several factors involved. CLINICAL CHALLENGES: Axillary wounds are often difficult to manage due to the frequent presence of infection, their histopathological characteristics and their location, where there is excessive tension and movement of the axillary tissues. Initial surgical treatment has a high reported incidence of failure and complications in the literature, with wound breakdown reported most commonly. Giving due consideration to the difficulties of managing these wounds, however, will help practitioners to decrease the occurrence of complications and the need for multiple procedures, and therefore improve the outcome. EQUIPMENT: Initial approach and surgical management can be achieved using standard medical equipment and surgical kit available to general practitioners. EVIDENCE BASE: This review discusses the surgical techniques reported in the literature to have successfully treated chronic axillary wounds and recommendations are also provided based on the authors' clinical experience.

INTRODUCTION: Side plates are worn by UK Armed Forces as part of the VIRTUS body armour and load carriage systems to protect the thorax and abdomen from high-velocity threats. The VIRTUS project has provided the impetus to objectively demonstrate the anatomical coverage provided by side plates. METHOD: CT scans of 120 male UK Armed Forces personnel were analysed to ascertain the vertical distance between the anterior axillary fold and iliac crest, and horizontal distance between anterior and posterior borders of the liver, delineating the boundaries of essential medical coverage from the side aspects. The percentage of shot-lines intersected by the existing Enhanced Combat Body Armour (ECBA) plates as well as an optimised plate based on the maximum potential dimensions of essential coverage was determined in the Coverage of Armour Tool. RESULTS: ECBA plates were 101 mm shorter and 4 mm narrower than a plate with dimensions providing essential medical coverage for the 50th percentile subject (157×315 mm). Coverage increased by 35% when using two ECBA plates as side coverage in addition to using the front and rear OSPREY plates in the VIRTUS vest. Two side plates with dimensions providing essential medical coverage for the 50th percentile increased anatomical coverage by a further 16%. CONCLUSIONS: This analysis has provided strong evidence that ECBA plates are already optimised for side protection, despite not being originally designed for this purpose. They are correctly positioned within the VIRTUS soft body armour vest and the width of the ECBA plate is only 3% less than what would be optimum size for the 50th percentile. Although the height of the plate could be increased to further enhance the anatomical coverage, it is unlikely that this would be acceptable in terms of the human factors, equipment integration or additional mass.

An 8-year-old child of Bajau Laut descent (a stateless tribe in Eastern Borneo and the Sulu archipelago) presented following a fall, with penetrating injury through the axilla caused by a stilt pole, exiting at the supero-anterior aspect of the left shoulder. Due to the lack of comprehension of modern medical treatment and poor language skills, the parents refused to consent for detailed radioimaging studies, nor surgical removal and exploration in the operating theatre. The removal of retained stilt pole was done in casualty area in Hospital Tawau, followed by local exploration under sedation and local analgesia. Despite the horrific injury, there was no limb-threatening neurovascular injury sustained. Management of such injury in the nomadic Bajau Laut population provides valuable insight and about the challenges and decisions of management.

Scar contracture is a significant complication of burn injury. This study aimed to describe outcomes of early axilla orthotic use at end of range abduction in children, following a burn to the axilla region. A retrospective review of 76 children (mean age 3.9 years [SD 3.6]) treated at a tertiary children's hospital from 2006 to 2016 was conducted. No child developed axilla contracture for the duration of the 2-year study follow-up with no adverse events recorded. If orthotic use was ceased <60 days post-burn, it was considered not an essential intervention to maintain range of movement, leaving 49 children using the orthotic ≥60 days. Compared with the children who ceased orthotic use in <60 days, children who required the orthotic ≥60 days had a significantly higher frequency of deep-dermal burn (59 vs 25%, p = .01), flame mechanism (25 vs 5%, p = .03), and burn injury distribution involving the anterior trunk, flank, and arm (18 vs 3%, p = .03). Early signs of contracture, considered loss of full axilla range or significant banding, developed in nine children within 3 months post-burn. With intensive therapy, all returned to full axilla range by 9 months post-burn. Children with skin tension at end of range shoulder movement at the 1-month clinical assessment were 11 times more likely to develop early signs of contracture (95% confidence interval [CI]: 1.9-62.1, p = .007). Intensive orthotic use at end of range shoulder abduction in children with axilla burns is well tolerated. When undertaken with ongoing therapist review, full axilla range can be maintained.

El síndrome de axillary web (SAW) se caracteriza por la aparición de «cordones» elevados debajo de la piel de la axila y el brazo medial en el período postoperatorio inmediato de una disección ganglionar axilar o biopsia de ganglio centinela. Los cordones suelen ir acompañados de limitación de la movilidad del hombro, principalmente la abducción. Su patogénesis (etiología linfática o venosa) a día de hoy es incierta, siendo significativa dada la alta prevalencia de este síndrome. Presentamos el caso de una paciente de 51 años con clínica de SAW a la cual le solicitamos una linfogammagrafía al diagnóstico y otra a los meses. Ambas informaron sobre la retención del trazador y de imágenes nodulares irregulares en el brazo, mejorando los resultados con la sintomatología del paciente. Con este caso clínico apoyamos el origen linfático de este síndrome, sin poder descartar una afectación venosa concomitante
Axillary web syndrome (AWS) is characterized by the development of elevated «cords» under the skin of the axilla and medial arm in the immediate postoperative period after axillary lymph node dissection or sentinel lymph node biopsy. There is usually decreased upper-extremity range of motion, mainly abduction. The pathogenesis (lymphatic or venous aetiology) is currently unclear, but is important, given the high prevalence of this syndrome. We present the case of a 51-year-old woman with symptoms of AWS, who underwent lymphoscintigraphy at diagnosis and again 2 months later. Both investigations showed tracer retention and irregular nodules in the arm. The results improved with the patient's symptoms. This case report supports a lymphatic aetiology of this syndrome, without ruling out concomitant venous involvement

Axillary nerve injury is common after brachial plexus injuries, particularly with shoulder luxation. Nerve grafting is the traditional procedure for postganglionic injuries. Nerve transfer is emerging as a viable option particularly in late referrals. At the proximal arm the radial and axillary nerves lie close by. Sacrificing one of the triceps muscle nerve branches induces little negative consequences. Transferring the long head of the triceps nerve branch is a good option to recover axillary nerve function. The surgical technique is presented in a video, stressing the steps to achieve a successful result. The video can be found here: https://youtu.be/WbVbpMuPxIE .

Postburn axillary adduction contractures should essentially be released for adequate shoulder function. Many methods have been described for this purpose. However, use of perforator flaps prevents harm to the underlying muscle and provides thin, pliable skin flaps. Despite the major advantages offered by perforator flaps, certain shortcomings of perforator flap surgery restrict their widespread use by inexperienced surgeons, including anatomic variations of perforator vessels. In order to rule out these shortcomings, we devised a new surgical approach with an initial incision that provides access to possible perforator systems on the dorsolateral thoracic area. The approach can easily be converted to a fasciocutaneous transposition flap when attempts for identification of a proper perforator fail. Nevertheless, a proper perforator can easily be reached through the exposure provided by this initial incision. With the intention of using perforator-based flap for reconstruction, we used this surgical approach for coverage in 14 cases of postburn axillary contractures. In 3 cases, conversions of the initial incision to local transposition flap (parascapular flap) were required. There was only 2 tip necrosis observed, which healed with secondary intention. Our current surgical approach may offer taking the advantages of using a true perforator flap for reconstruction while avoiding a second stress on the patient when an operative plan for perforator flap harvest fails.

La paraqueratosis granular axilar es una entidad poco frecuente debida a una alteración del proceso de queratinización, lo que produce un engrosamiento de la epidermis a expensas de la capa córnea. La etiología es desconocida, implicándose, entre otros, a agentes irritantes. Presentamos un caso de paraqueratosis granular axilar en una mujer de 31 años, asociada a un posible factor irritante, el desodorante, localizada en ambas axilas, sin mejoría ante el tratamiento farmacológico (corticoides y antifúngico) y con remisión completa tras la retirada del mismo (AU)
Granular parakeratosis is a rare entity that results from a disorder of keratinization, producing an epidermal thickening of the stratum corneum. The etiology is unknown although some factors, such as irritating agents, have been implicated. We present a case of granular parakeratosis associated with an irritating agent (a deodorant) in both axillae of a 31-year-old woman. She did not respond to therapy with corticosteroid and antifungal agents but the GP resolved spontaneously when use of the deodorant was stopped (AU)

BACKGROUND: Reconstruction of postburn axillary contractures is difficult and particularly challenging without healthy adjacent soft tissue for axillary scar resurfacing. In this case, a free soft-tissue transfer is among the best treatment options. Here, we describe our experience with free anterolateral thigh (ALT) flap for reconstruction in postburn axillary contractures. METHODS: We enrolled 10 patients with postburn axillary contractures from August 2003 to July 2015. They all underwent wide scar contracture release through a transverse incision from the anterior axillary fold to the posterior axillary fold. The ALT flap was subfascially raised. The huge soft tissue defect after scar release was resurfaced with the ALT flap. RESULTS: Eight male patients and 2 female patients (age, 16-64 years; mean, 46 years) were included. The mean total burn surface area, follow-up time, duration between injury onset and free-flap transfer surgery, and flap size were 48%, 27 months, 7.7 months, and 12 × 23 cm, respectively. The most common recipient vessels were the thoracodorsal artery and vein (77%). The mean improvement in the range of motion of shoulder abduction was 86 degrees (range, 60-130 degrees). The mean operative time was 7 hours. All flaps survived without reexploration or failure. All but 1 donor site was managed by split-thickness skin grafting. No infection, hematoma, or deaths were noted postoperatively. Transient brachial palsy was noted in a 16-year-old male patient postoperatively, with full recovery 3 months after. CONCLUSIONS: For postburn axillary contractures without healthy adjacent soft tissue for scar resurfacing, ALT flap reconstruction represents a suitable treatment option. It allows simultaneous surgery on both the donor and recipient sites, without the need to change the patient's position. Furthermore, the ALT flap provides sufficient soft tissue and blood flow for reconstruction, leading to satisfactory functional outcomes.

Objetivo: descripción de tres casos clínicos con ruptura de los implantes mamarios de silicona, sus formas de presentación, pruebas diagnósticas utilizadas y revisión de la literatura existente. Sujetos y métodos: presentamos tres casos de siliconomas tras rotura de implante mamario. Resultados y conclusiones: las prótesis de silicona han sido ampliamente utilizadas para aumento mamario con fines estéticos y para reconstrucción postmastectomía. La rotura de los implantes mamarios es una complicación reconocida en este tipo de cirugía y su incidencia se relaciona directamente con la edad de la prótesis. La rotura extracapsular puede dar lugar a una dispersión de la silicona hacia los ganglios linfáticos axilares provocando una reacción de cuerpo extraño y la formación de granulomas. La mayoría son un hallazgo casual y no hay evidencia de que jueguen un papel en el desarrollo de enfermedad sistémica (AU)
Objective: Description of three cases with ruptured silicone breast implants, forms of presentation, diagnostic tests used and review of the literature. Subjects and methods: Three cases of siliconomas after breast implant rupture. Results and conclusions: The silicone implants have been widely used for cosmetic breast augmentation and reconstruction postmastectomy. The breast implant rupture is a recognized complication in this type of surgery and its incidence is directly related to the age of the prosthesis. Extracapsular rupture can lead to a dispersion of silicone to the axillary lymph nodes causing a foreign body reaction and granuloma formation. Most are incidental findings and no evidence that play a role in the development of systemic disease (AU)

BACKGROUND: Although open injuries involving the brachial plexus are relatively uncommon, they can lead to permanent disability and even be life threatening if accompanied by vascular damage. We present a case report of a brachial plexus injury in which the urgency of the situation precluded the use of any ancillary diagnostic examinations and forced a rapid clinical assessment. CASE PRESENTATION: We report a case of a Portuguese man who had a stabbing injury at the base of his left axilla. On observation in our emergency room an acute venous type of bleeding was present at the wound site and, as a result of refractory hypotension after initial management with fluids administered intravenously, he was immediately carried to our operating room. During the course of transportation, we observed that he presented hypoesthesia of the medial aspect of his arm and forearm, as well as of the ulnar side of his hand and of the palmar aspect of the last three digits and of the dorsal aspect of the last two digits. Moreover, he was not able to actively flex the joints of his middle, ring, and small fingers or to adduct or abduct all fingers. Exclusively relying on our anatomical knowledge of the axillary region, the site of the stabbing wound, and the physical neurologic examination, we were able to unequivocally pinpoint the place of the injury between the anterior division of the lower trunk of his brachial plexus and the proximal portion of the following nerves: ulnar, medial cutaneous of his arm and forearm, and the medial aspect of his median nerve. Surgery revealed a longitudinal laceration of the posterior aspect of his axillary vein, and confirmed a complete section of his ulnar nerve, his medial brachial and antebrachial cutaneous nerves, and an incomplete section of the ulnar aspect of his median nerve. All structures were repaired microsurgically. Three years after the surgery he showed a good functional outcome. CONCLUSIONS: We believe that this case report illustrates the relevance of a sound anatomical knowledge of the brachial plexus in an emergency setting.

BACKGROUND: Postburn axillary contractures are common and significantly impact quality of life. Simple release combined with split thickness skin grafting necessitates a donor site, requires immobilization, and may result in poor functional outcome. Common methods of adjacent tissue rearrangement are not well designed to treat broad linear contractures. Flaps from the back, flank, or arm can be used, but may come with significant donor site morbidity. We demonstrate the use of the STARplasty, a novel adjacent tissue rearrangement initially developed to treat neosyndactyly, as a useful reconstructive option for the release of Kurtzman type 1 posterior or anterior axillary contractures. METHODS: A retrospective review was performed to identify patients who underwent STARplasties for treatment of type 1 axillary burn contractures. All reconstructions were performed by a single surgeon at a single ABA burn center (April 2011 to December 2015). A version of the surgical STARplasty technique previously described for treatment of neosyndactyly was modified for use in the axilla. Patient and injury demographics, as well as complications and outcome, were collected. RESULTS: Twelve patients with upper extremity burns underwent 16 primary STARplasties for treatment of axillary contractures. Three patients underwent simultaneous bilateral procedures. The majority (15/16) of the primary procedures were used to address contractures of the anterior axillary fold. Mean patient age was 51 (R 38-63) and average burn size was 35% (R 18-80). Average time from initial injury to primary reconstruction was 11.1 months (R 3-54). One patient required revision for persistent contracture and another experienced wound dehiscence that ultimately required split-thickness skin grafting. No other significant complications were noted, and all remaining patients had closed wounds and full range of motion by 30 days postprocedure. CONCLUSIONS: Axillary contractures remain common despite improvements in physical/occupational therapy. While common techniques, such as z-plasty, continue to be helpful for the surgical release of narrow contractures with bilateral laxity, axillary contractures are typically broad based and often contain only unilateral unburned tissue. Based on our experience, the axillary STARplasty represents a safe and efficacious technique to be considered in the case of broad-based contractures involving either the anterior or posterior axillary fold.

Introdução: São apresentados dois casos de retração em região axilar após queimadura em que a correção cirúrgica foi realizada empregando-se zetaplastias múltiplas. Apresentamos uma tática de marcação que visa facilitar o aprendizado desse procedimento pelos residentes de Cirurgia Plástica. Métodos: Dois pacientes com retrações axilares e de membros superiores após queimadura com líquido aquecido foram submetidos à correção cirúrgica empregando-se a zetaplastia múltipla. A tática de planejamento proposta nesse estudo preconiza primeiro a marcação do retalho triangular localizado no ponto médio da retração axilar, o qual irá avançar e cruzar o eixo da cicatriz, e a partir daí o desenho dos retalhos subsequentes com ângulo de 60° entre si. Acreditamos que essa sistematização da marcação facilita o planejamento e aprendizado da plástica em Z. Resultados: Os pacientes apresentaram adequadas amplitude de movimento e recuperação funcional do membro acometido no pós-operatório. Não houve necrose das extremidades dos retalhos, que preconizamos serem cuidadosamente trabalhadas e um pouco arredondadas; e a execução do procedimento foi simples devido à tática de marcação que aplicamos. Conclusão: A tática de marcação que apresentamos é reprodutível e de fácil aprendizado. A zetaplastia múltipla foi eficaz em restabelecer a amplitude de movimento das áreas com sequela de queimadura tratadas com esse método.
Introduction: Herein, we present two cases of post-burn retraction of the axillary region, which were subsequently surgically corrected using multiple Z-plasties. We present a marking strategy to facilitate the learning of this procedure by plastic surgery residents. Methods: Two patients with axillary and upper limb retractions due to burns with hot liquids were surgically treated using multiple Z-plasties. The strategy proposed in this study recommends the marking of the triangular flap located at the midpoint of the axillary retraction, which then advances and crosses the axis of the scar. Then, subsequent flaps are made at an angle of 60° to each other. We believe that this systematization of marking facilitates the planning and learning of Z-plasty. Results: The study patients achieved an adequate range of motion and functional recovery of the affected limb postoperatively. We observed no cases of necrosis of the flap ends, which should be carefully worked and slightly rounded. The execution of the procedure was simple using the suggested marking strategy. Conclusion: The presented marking strategy was reproducible and easy to learn. Multiple Z-plasties were effective in restoring the range of motion of the areas affected by burns that were treated using this method.

Exsanguination from wounds in the so-called junctional regions of the body (i.e., the neck, the axilla, and the groin) was responsible for 19% of the combat fatalities who died from potentially survivable wounds sustained in Afghanistan or Iraq during 2001 to 2011. The development of improved techniques and technology to manage junctional hemorrhage has been identified in the past as a high-priority item by the Committee on Tactical Combat Casualty Care (CoTCCC) and the Army Surgeon General's Dismounted Complex Blast Injury (DCBI) Task Force. Additionally, prehospital care providers have had limited options with which to manage hemorrhage resulting from deep, narrow-track, penetrating trauma. XStat™ is a new product recently approved by the US Food and Drug Administration as a hemostatic adjunct to aid in the control of bleeding from junctional wounds in the groin or axilla. XStat has now been recommended by the CoTCCC as another tool for the combat medical provider to use in the management of junctional hemorrhage. The evidence that supports adding XStat to the TCCC Guidelines for the treatment of external hemorrhage is summarized in this paper.

INTRODUCTION: Defining the minimum anatomical structural coverage required to protect from ballistic threats is necessary to enable objective comparisons between body armour designs. Current protection for the axilla and arm is in the form of brassards, but no evidence exists to justify the coverage that should be provided by them. METHOD: A systematic review was undertaken to ascertain which anatomical components within the arm or axilla would be highly likely to lead to either death within 60â min or would cause significant long-term morbidity. RESULTS: Haemorrhage from vascular damage to the axillary or brachial vessels was demonstrated to be the principal cause of mortality from arm trauma on combat operations. Peripheral nerve injuries are the primary cause of long-term morbidity and functional disability following upper extremity arterial trauma. DISCUSSION: Haemorrhage is managed through direct pressure and the application of a tourniquet. It is therefore recommended that the minimum coverage should be the most proximal extent to which a tourniquet can be applied. Superimposition of OSPREY brassards over these identified anatomical structures demonstrates that current coverage provided by the brassards could potentially be reduced.

OBJECTIVES: The strain placed across the axillary nerve during the deltoid-splitting approach could correlate with microtrauma and place the patient at risk of a neuropraxia or more permanent injury. The purposes of this study were to evaluate the change in length and strain exhibited by the axillary nerve during the deltoid-splitting approach and to determine the presence of any microscopic structural damage. METHODS: The axillary nerve was identified through a lateral deltoid-splitting approach in 10 fresh-frozen cadaver specimens. Two suture tags were placed near the lateral margins of the incision. The initial distance between the 2 tags was measured and the distance at each retractor click of a Kölbel retractor until full expansion (6 clicks). The retractor was then released for a 1-minute break at 30, 60, 90, and 120 minutes. The strain at each interval was calculated as change in length divided by the initial distance. The section of nerve in the field of exposure was excised for histologic analysis. RESULTS: The location of the axillary nerve was 6.32 cm (range, 5.20-7.6 cm) from the anterolateral aspect of the acromion. The mean final increase in length was 8.42 mm (range, 6.43-12.26 mm). The strain increased to a final mean of 51% (range, 28%-99%). Histologic analysis confirmed disruption of the myelin sheaths and axonal retraction. CONCLUSIONS: This study demonstrated a progressive, irreversible increase in axillary nerve length and strain, resulting in microscopic damage to the neuronal structure during a deltoid-splitting approach. Prolonged soft tissue retraction can place the axillary nerve at substantial risk for injury.
