RESUMEN
Background: The reconstruction of the thumb's pulp is challenging when considering that there is no consensus on which local flap will provide better prognosis and less financial impact. The aim of this study was to analyze the outcomes of the most used flaps for the trauma to the volar substance of the thumb, validating the main indications. Methods: This systematic review adhered to PRISMA guidelines and electronic searches were conducted in multiple databases (MEDLINE/PubMed, Virtual Health Library, Embase and Scopus) with studies published in the last ten years - until April 2022. Results: The search resulted in the screening of 573 records, and twenty studies were included. Among the flaps analyzed and compared by outcomes and prognostic factors, there are First Dorsal Metacarpal Artery (FDMCA), modified (MFDMCA), Moberg flap, Heterodigital Neurovascular Island, Neurovascular Island Pedicle and Modified Littler. Conclusion: Through this literature review, we can analyze different flaps widely used in the daily life of hand surgeons. The flaps that were also positive in a global context, but with few criticisms, are the MFDMCA, Moberg Flap, Neurovascular Island pedicle flap and FDMCA. However, it is important for the surgeon to consider different prognostic factors when choosing the flap, since these aspects directly impact the return to daily activities after the procedure.

Nerve compression by anomalous muscles located at the wrist and distal forearm is an infrequent condition. Accessory muscles may compress underlying structures in the Carpal Tunnel region or ulnar canal , producing pain and paresthesia. Two cases of ulnar and median nerve compression, caused by prominent accessory muscles at the distal forearm, are described. Literature review is presented.
La compresión nerviosa causada por vientres musculares anómalos localizados en la muñeca y en el tercio distal del antebrazo es una condición poco frecuente. Músculos accesorios pueden comprimir estructuras subyacentes en la región del túnel del carpo o en el canal de ulnar, produciendo dolor y parestesia. Se presentan dos casos de compresión de los nervios ulnar y mediano en el tercio distal del antebrazo, causados por vientres musculares prominentes de músculos accesorios del antebrazo. Se presenta una revisión de la literatura.

Traumatic finger amputations are common, causing significant functional and cosmetic deficits. Microsurgical replantation techniques are the mainstay of treatment for most such injuries although they require adequate conservation of the amputated segment for a successful result. In distal finger amputations, replantation is the procedure of choice, as long as the amputated fragment is viable. If replantation is not an option, reposition + flap using a neurovascular flap can be an efficient option, as this offers improved skin coverage. To the best of our knowledge, this case illustrates the longest cold ischaemic time with a successful outcome.
RESUMEN
A epidermólise bolhosa é uma doença hereditária que causa alterações em proteínas estruturais da pele e consequente fragilidade da epiderme. Manifesta-se por surgimento de flictenas por todo o corpo e deformidades funcionais de membros, especialmente nas mãos, sendo que as formas mais características são pseudossindactilia e contraturas. Neste trabalho, descrevemos o caso de um paciente de 12 anos com deformidades nas mãos e flictenas pelo corpo que foi submetido à cirurgia da mão para recuperação da movimentação funcional (AU)
Epidermolysis bullosa is a hereditary disease that causes changes in structural proteins of the skin and consequent fragility of the epidermis. It is manifested by the appearance of blisters all over the body and functional deformities of limbs, especially the hands, and the most characteristic forms are pseudosyndactyly and contractures. In this paper, we describe the case of a 12-year-old patient with deformities in his hands and blisters over the body who underwent hand surgery for recovery of functional movement (AU)

The secondhand exposure to cigarette smoke is being considered evil, and damage caused by this passive exposure has been proven by several studies. To investigate the effects of sidestream smoke exposure on random-pattern skin flap survival, 20 female rats were separated into 2 groups: group A (n = 10) was exposed 6 weeks to the smoke from the burning cigarette (passive smoking) and group B (n = 10) was the control group. After 6 weeks of exposition, a dorsal McFarlane flap of 4 × 10 cm was performed in all rats. Two weeks after this procedure, the ratio of necrotic and total areas was calculated using computer programs. The median area of necrosis in group A was 29.5%, significantly higher than that in group B with 17.5% (P < 0.024). In conclusion, this study suggests increased risk of random-pattern skin flap necrosis after sidestream exposure to cigarette smoke.

The aim of this study was to evaluate the effect of Platelet Rich Plasma (PRP) and Platelet Rich Fibrin (PRF) on peripheral nerve repair. Thirty-two Wistar rats were randomly divided into four equal treatments groups: autologous nerve grafts (ANG), silicon tube plus saline solution (SS), silicon tube plus PRP, and silicon tube plus PRF. In ANG group, 10 mm segment from sciatic nerve was excised and reimplanted between the nerve stumps. In the SS, PRP, and PRF groups, 5 mm segment from sciatic nerve was excised and bridged with a 12 mm silicone conduit to create a 10 mm nerve gap. The conduit was filled in accordance with the different treatments. Walking track analysis was performed periodically and on the 90th post-operative day histomorphometric analysis was performed. The ANG, PRF, and PRP groups presented a significant functional improvement in relation to the SS group (P = 0.001) on 90 days after surgery. Histomorphometric analysis demonstrated that the ANG group achieved a larger nerve fiber diameter in proximal stump while comparing with the SS group (P =0.037) and showed larger fiber diameter in median stump in comparison to the PRP group (P = 0.002) and PRF group (P = 0.001). Axonal diameter and myelin sheath thickness showed no statistical significant difference between the groups in the three stumps (P ≥ 0.05). This study suggests that PRP and PRF have positive effects on the functional nerve recovery; however, these groups don't achieve a significant improvement on the histomorphometric analysis.

PURPOSE: To describe the results in patients treated with distraction osteogenesis combined with free nail graft after distal phalanx amputation. METHODS: We analyzed 14 patients with distal phalanx amputation (13 women). Mean age was 35 years. There were 9 amputations of the index finger, 3 of the middle finger, and 1 each of the thumb and ring finger. We started bone distraction 7 days after surgery, with 1 mm distraction every 3 days. After bone elongation, we inserted a free composite nail graft at the dorsal tip of the distracted finger. We evaluated distraction length, consolidation time, aesthetic result (using the Foucher and Leclère score), and complications. RESULTS: The mean bone elongation was 17 mm and mean consolidation time was 149 days. Nail cosmetic results were satisfactory; the mean total Foucher score was 14 out of 20. Mean individual scores were patient's opinion (7.8 out of 10), adequate length (1.2 out of 2.5), adequate alignment (1 out of 1), adequate width (1.8 out of 4), and dorsal scar quality (2.2 out of 2.5). The mean total Leclère score was 14 out of 20. All patients retained sensibility in the grafted area and none had healing abnormalities. The mean opinion about the donor site was 7.5 out of 8. Nail growth less than 50% occurred in 2 patients. Mean follow-up was 62 months. CONCLUSIONS: Distraction osteogenesis combined with free nail graft is a therapeutic option when replantation is not an option or when it fails. However, treatment takes time and requires the involvement of the patient, family, and medical team.

O condrossarcoma mesenquimal é uma variante rara de condrossarcoma, que raramente atinge os tecidos extraósseos. Este tipo de tumor normalmente ocorre em adultos jovens, sendo altamente agressivo, e tende a apresentar recorrência tardia e metástases a distância. No exame histológico, caracteriza-se por apresentar abundantes células mesenquimais indiferenciadas entre ilhas de células cartilaginosas bem diferenciadas. O tratamento cirúrgico com ressecção completa do tumor é o tratamento padrão para o condrossarcoma mesenquimal. Apresentamos aqui o caso de uma paciente de 56 anos que apresentava um condrossarcoma mesenquimal de grandes proporções na região do couro cabeludo. O diagnóstico da lesão foi tardio e, após o estadiamento da mesma, a paciente foi submetida a ressecção total da neoplasia e reconstrução com retalho de rotação extenso de couro cabeludo e enxertia de pele parcial. No presente estudo, pode-se concluir que ainda não há um tratamento realmente efetivo para o condrossarcoma mesenquimal avançado
Mesenchymal chondrosarcoma is a rare variant of chondrosarcoma, which rarely reaches the extra-osseous tissues. This type of tumor usually occurs in young adults and is highly aggressive, tending to present late recurrence and distant metastases. On histological examination it is characterized by abundant undifferentiated mesenchymal cells between islands of well differentiated cartilage cells. Surgical treatment with complete surgical resection is the standard treatment for mesenchymal chondrosarcoma. Here we present the case of a 56-year-old female patient who had a mesenchymal chondrosarcoma of great proportions in the region of the scalp. The diagnosis was late and after the staging of it, the patient underwent total resection of the tumor and reconstruction with extensive rotation flap of scalp and partial skin graft. In this study we can conclude that as yet there is no really effective treatment for advanced mesenchymal chondrosarcoma

PURPOSE: To evaluate the long-term (6-y) results of Wilhelm's wrist denervation technique used as an isolated procedure for painful conditions of the wrist. METHODS: We conducted a retrospective review of 49 wrist denervations that were performed as isolated procedures in patients with painful wrist conditions. Indication for surgery was degenerative osteoarthritis of the wrist caused by scaphoid nonunion advanced collapse in 19 patients, Kienböck's disease in 13 patients, and primary degenerative osteoarthritis in 17 patients. RESULTS: The results were analyzed as a group and by comparing the 3 etiologies. Average pain improvement after surgery for all groups was 68% ± 8% after the first month and reached a plateau at the end of the first year, with the percentage remaining stable at 36 months at 79% ± 4%. Grip strength on the treated side improved from 43% of the opposite side before denervation to 69% of the opposite side. The range of motion showed improvements in all axes of movement, without statistical differences between groups. Radiological evaluation after 72 months revealed worsening in 34 patients. There was no difference in results between the 3 groups with regard to grip strength, range of motion, or pain relief obtained. CONCLUSIONS: Wrist denervation resulted in improvement in pain scores in 39 patients despite radiological deterioration noted in 34 after 6 years. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: The aim of this study was to experimentally compare end-to-end and end-to-side neurorrhaphy in perineural window model after motor nerve lesion, evaluating which one was the most effective to preserve nerves. Also, differences in motor and sensorial nerve regeneration were tested to verify differences in nerve regeneration. METHODS: A total of 20 adult male Wistar rats were randomly assigned to 5 groups, and, in each one, a different treatment was performed: besides the control group, and end-to-end or end-to-side graft with motor or sensorial nerves was performed. Silastic sheet was used as a mechanical barrier to prevent innervation from adjacent nerves. After 16 weeks, the specimens were histologically assessed and wet weight was evaluated as a direct parameter of atrophy. RESULTS: The end-to-end neurorrhaphy group presented the best results in terms of mass preservation, but it did not differ significantly from the control group. Motor nerves presented similar results in muscular atrophy. The end-to-side neurorrhaphy group with sensory nerve as donor showed the worst results. CONCLUSIONS: The use of sensory nerves to preserve skeletal muscle trophism is not justified, since, according to our model, it affects 50% to 80% of the muscle mass in a period of 16 weeks. End-to-side neurorrhaphy was demonstrated to be an option for re-enervation of a nerve-deprived motor muscle in selected cases.

O objetivo deste trabalho é discutir as várias opções terapêuticas para as perdas de substâncias do terço distal da perna, com destaque para o retalho desepidermizado. Para ilustrar, apresentamos o caso de um paciente com perda de substância extensa no terço distal anterior da perna após ressecção de sarcoma da bainha de nervo periférico. Esta é uma área de difícil reconstrução devido à escassez de zonas doadoras regionais, pelo qual o retalho desepidermizado aparece como uma excelente opção na medida em que promove total cobertura do defeito sem prejuízos estéticos ou funcionais maiores à área doadora (AU)
This work discusses the various therapeutic options for the losses of substances in the distal third of the leg, highlighting the de-epithelialized flap. To illustrate, we present the case of a patient with extensive loss of substance in the distal third of the leg after resection of peripheral nerve sheath sarcoma. Reconstruction in this area is difficult due to the scarcity of regional donor zones, for which the de-epithelialized flap appears as an excellent option as it promotes total covering of the defect with no major aesthetic or functional impairments to the donor area (AU)

Um modelo experimental de lesão raquimedular com localização precisa e reproduzível é uma ferramenta extremamente importante para o estudo de novas terapias em lesões raquimedulares. OBJETIVOS: Desenvolver um modelo experimental de lesão raquimedular em ratos que produza lesão completa (paraplegia) com o posicionamento de um sistema que permita o acesso de agentes próximo ao local da lesão para testar agentes terapêuticos locais. MÉTODOS: Quinze ratos Wistar foram submetidos à transecção cirúrgica da medula espinhal, realizada com o uso de tesoura ao nível dos corpos vertebrais de T-13 a L-3 e, ao final do procedimento, à implantação de um cateter subcutâneo para o acesso de agentes terapêuticos locais ao local da lesão. RESULTADOS: Um modelo experimental de paraplegia foi consistentemente desenvolvido com a adição suplementar de um cateter para o acesso de agentes terapêuticos locais ao local da lesão. CONCLUSÃO: Um modelo animal de lesão raquimedular e um sistema para o acesso de agentes terapêuticos locais pode ser reproduzido para o estudo de diferentes modificadores da resposta regenerativa em um modelo de ratos com lesão raquimedular.
An experimental model of spinal cord injury at a precise and reproducible site is an extremely important tool for studying new therapies in spinal cord injuries. OBJECTIVES: To develop an experimental model of spinal cord injury in rats that is able to produce a complete injury (paraplegia) and placing a system enabling agents access close to injury site in order to test local therapeutic agents. METHODS: Fifteen Wistar rats were submitted to surgical transection of the spine, performed by using scissors at the level of T-13 to L-3 vertebral bodies, and, at the end of the procedure, to the insertion of a subdermal catheter intended to enable local therapeutic agents access to injury site. RESULTS: An experimental model of paraplegia was consistently developed by adding a supplementary catheter for local therapeutic agentsÆ access to injury site. CONCLUSION: An animal model of spinal cord injury and a system for local therapeutic agents access can be reproduced for the study of different modifiers of the regenerative response in a model of rats with spinal cord injury.

Lower limb reconstruction, especially for the aquilian and calcaneal regions, represent a great challenge for the plastic surgeon. Among the existing options of cutaneous coverage, the distally pedicled adipofascial flap may reach even the most distal zones. From April 1995 to May 2002, 15 adipofascial flaps to the cutaneous coverage of the distal-third leg were performed. The reconstruction was immediate in eight patients. In one case, partial tissue necrosis was observed.

OBJETIVOS: Foram avaliados os efeitos do uso de células tronco da medula óssea (CTM) e do plasma rico em plaquetas (PRP) na regeneração de nervos periféricos, utilizando um modelo estabelecido de regeneração de nervo ciático em ratos. MÉTODOS: Um defeito nervoso de 10 mm foi reconstruído com a utilização de um tubo de silicone preenchido com CTM, PRP ou ambos. O grupo controle recebeu somente o tubo de silicone. Foi realizado ainda um quinto grupo no qual o intervalo foi reconstruído utilizando o segmento ressecado do nervo. A função motora foi testada seis semanas após a cirurgia utilizando teste de marcha. Após o teste motor, os ratos foram anestesiados, o nervo ciático e o tubo foram ressecados e foi realizada microscopia eletrônica de transmissão. RESULTADOS: A análise quantitativa demonstra uma melhora na recuperação funcional no grupo CTM em comparação com os demais grupos. Regeneração nervosa foi demonstrada no grupo CTM por microscopia eletrônica de trasmissão com uma recuperação praticamente completa da anatomia neural. CONCLUSÃO: Nossos resultados sugerem que o uso de CTM associado com a técnica de tubulização promove uma satisfatória recuperação da função motora e regeneração nervosa.
OBJECTIVES: The effects of the use of bone marrow stem cells (MSC) and platelet-rich plasma (PRP) on peripheral nerves regeneration were assessed by using an established model of sciatic nerve regeneration in rats. METHODS: A 10-mm nervous defect was reconstructed by using a silicone tube filled with MSC, PRP or both. The control group received only the silicone tube. A fifth group was also set, in which the interval was reconstructed by using a dried segment of the nerve. Motor function was tested six weeks after surgery, by means of a gait test. After motor test, the rats were anesthetized, the sciatic nerve and the tube were dried, and the transmission electronic microscopy was performed. RESULTS: The quantitative analysis shows an improved functional recovery in MSC group compared to the other groups. Nervous regeneration was reported for MSC group by means of transmission electronic microscopy with an almost full recovery of the neural anatomy. CONCLUSION: Our results suggest that the use of MSC combined with tubing technique yields a satisfactory recovery of motor function and nervous regeneration.

Introdução: A primeira causa de maus resultados após uma reparação de tendão flexor em zona 2 é a formação de aderências. Um protocolo de mobilização precoce poderia ajudar a diminuir tais aderências, sob risco de aumentar a taxa de rupturas. Este estudo objetiva avaliar o resultado funcional do reparo de lesões de flexores na zona 2. Método: Foram tratados 136 tendões flexores da mão, na zona 2, em 82 pacientes, todos com lesões unidigitais, com secção completa de ambos os tendões, no caso dos dedos largos, o do flexor pollicis longus, no caso de polegar, submetidos a um protocolo de flexão e extensão ativa precoce. Os resultados foram classificados segundo a Inter¬national Federation for Societies for Surgery of the Hands (IFSSH) e pela classificação de Strickland. Resultados: Os resultados funcionais dos dedos longos foram excelentes (72,2 per cent), bons (26,0 per cent) e regulares (1,9 per cent), de acordo com a classificação de Strickland e bons (81,5 per cent), regulares (16,6 per cent) e pobres (1,9 per cent), segundo a classificação da IFSSH. Os resultados do polegar foram excelentes (96,4 per cent) e regulares (3,6 per cent), de acordo com a classificação de Strickland e excelentes (82,1 per cent), bons (14,3 per cent) e pobres (3,6 per cent), de acordo com a classificação da IFSSH. A taxa de ruptura foi de 6,09 per cent; não obstante, os resultados funcionais dos pacientes reoperados foram satisfatórios. Conclusões: O presente estudo sugere que o protocolo de mobilização ativa precoce no pós-operatório das tenorrafias de flexores da mão em zona 2 pode proporcionar bons resultados funcionais em lesões no dedo único.

This study describes the anatomy of the dorsal cutaneous vascular system of 180 digits (36 thumbs, index, middle, ring, and little fingers) from 18 pairs of fresh human cadaver hands. The aim of this paper is to incorporate the anatomic data into the current way of designing the homodigital adipofascial turnover flap for cutaneous coverage of the dorsum of the finger. We have carried out an anatomic study in preserved cadaver hands to define the distance between the joint and the origin of the dorsal cutaneous branches of the proper palmar digital artery in the proximal and middle phalanx of the long fingers and for the thumb to metacarpal and interphalangeal joint. All branches of the proper digital artery that ran to the dorsal skin were then identified, and their diameters and the distances of their origins from the proximal interphalangeal joint were measured. We showed that 2 constant branches in the proximal and middle phalanx from each proper digital artery have consistent sites of origin at predictable distances from the proximal interphalangeal joint for the long fingers and the metacarpal and interphalangeal joint for the thumb. The flap survival was excellent, and no donor site complications were observed. We showed that these branches have consistent sites of origin at predictable distances from the proximal interphalangeal joint. The adipofascial turnover arterial flap has appeared as an excellent alternative to achieve early coverage of cutaneous wounds at the dorsal aspect of the fingers.

Introdução: A reconstrução do segmento ósseo mandibular utilizando retalhos ósseos vascularizados após perdas segmentares é o método mais utilizado na atualidade, tendo zonas doadoras que incluem a fibula, o rádio, a escápula e a crista iliaca. Método: Apresenta-se uma análise descritiva e retrospectiva da expenência dos autores em 45 casos de reconstrução mandibular microci-rúrgica em pacientes com defeitos ósseos da mandíbula. Foram uftlizados enxertos ósseos vascularizados, ou da crista ilíaca ou da fíbula, avaliando o comportamento dos enxertos em relação a sua facilidade de uso e viabi-lidade de uma posterior ósseo-integração dos implantes. Resultados: O retalho microcirúrgico de fíbula foi utili-zado em 10 pacientes, e o retalho de crista ilíaca foi em outros 35 casos, Em todos os casos nos quais se utili-zou a fíbula, houve necessidade de osteotomla do segmen-to ósseo transferido e em somente quatro casos a implan-tação dentária foi satisfatória, No entanto, o retalho de crista ilíaca foi realizado sem a necessidade de os-teotomia e toi possível a colocação dos implantes nos 35 retalhos, não sendo observada em nenhum caso falha na integração dos implantes, sendo possívei o retorno à mastigação após 6 meses, Conclusões: As reconstruções realizadas com o retalho microcirúrgico de crista ilíaca evidenciaram bons resultados funcionais. Quanto aos casos em que se utilizou o retalho de fíbula, obtiveram-se piores resultados no que tange à integração dos implantes dentários.
