Clinical effects of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns / 中华烧伤杂志

Objective: To explore the clinical effects of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns. Methods: A retrospective observational study was conducted. From May 2018 to April 2021, 12 male patients with thumb destructive defects caused by electrical burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 27 to 58 years, including 10 cases with degree Ⅲ thumb defect and 2 cases with degree Ⅳ thumb defect after thorough debridement. The thumb was reconstructed with free hallux-nail flap combined with composite tissue flap of the second phalangeal bone, joint, and tendon with skin island. The donor site of hallux-nail flap was covered with artificial dermis in the first stage and performed with continuous vacuum sealing drainage, and covered with medium-thickness skin graft from the groin site in the second stage. The donor site in the second toe was filled and fixed with iliac bone strips. The survival of reconstructed thumb was observed 1 week after the reconstruction surgery, the survival of skin graft in the donor site of hallux-nail flap was observed 2 weeks after skin grafting, and the callus formation of the reconstructed thumb phalanx and the second toe of the donor foot was observed by X-ray 6 weeks after the reconstruction surgery. During the follow-up, the shape of reconstructed thumb was observed and the sensory function was evaluated; the function of reconstructed thumb was evaluated with trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; whether the interphalangeal joints of the hallux and the second toe were stiff, the scar hyperplasia of the foot donor site, and whether the walking and standing functions of the donor feet were limited were observed. Results: One week after the reconstruction surgery, all the reconstructed thumbs of the patients survived. Two weeks after skin grafting, the skin grafts in the donor site of hallux-nail flap of 11 patients survived, while the skin graft in the donor site of hallux-nail flap of 1 patient was partially necrotic, which was healed completely after 10 days' dressing change. Six weeks after the reconstruction surgery, callus formation was observed in the reconstructed thumb and the second toe of the donor foot of 10 patients, the Kirschner wires were removed; while callus formation of the reconstructed thumb was poor in 2 patients, and the Kirschner wires were removed after 2 weeks of delay. During the follow-up of 6 to 24 months, the shape of reconstructed thumb was similar to that of the healthy thumb, the discrimination distance between the two points of the reconstructed thumb was 7 to 11 mm, and the functional evaluation results were excellent in 4 cases, good in 6 cases, and fair in 2 cases. The interphalangeal joints of the hallux and the second toe of the donor foot were stiff, mild scar hyperplasia was left in the donor site of foot, and the standing and walking functions of the donor foot were not significantly limited. Conclusions: The application of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns adopts the concept of reconstruction instead of repair to close the wound. It can restore the shape and function of the damaged thumb without causing great damage to the donor foot.

Condroma de partes moles relato de caso e revisão da literatura / Soft tissue chondroma case report and review of the literature

O presente estudo tem o objetivo de apresentar um relato de caso sobre condroma extra-esquelético ou de partes moles, uma lesão rara e benigna diagnosticada através da clínica, radiologia e exame histopatológico. O paciente (24 anos) compareceu ao Setor de Ortopedia do Hospital Unimed Betim com queixa de aumento de volume no polegar esquerdo, indolor há aproximadamente um ano. Durante o exame físico verificou-se presença de uma lesão nodular, de consistência dura, móvel, indolor que não acarretava em alteração funcional do dedo. O paciente foi encaminhado para setor de radiologia do hospital onde foi realizado RX e posteriormente ultrasonografia e ressonância magnética do polegar esquerdo. Diante dos achados dos estudos de imagem a equipe optou pela biópsia excisional da lesão. O exame histopatológico confirmou o diagnóstico de condroma extra-esquelético. Os elementos definidores do condroma de partes moles são: 1) curso clinico benigno e sintomatologia frusta; 2) ausência de conexão entre o tumor e estruturas adjacentes como periosteo, capsula articular ou osso; 3) crescimento lento; 4) ausência de prevalência por sexo; 5) características radiológicas e histológicas do tumor. O diagnóstico raramente é aventado quando confrontamos tumores de partes moles das mãos. A excisão é simples e deve ser completa para se evitar recorrências. A avaliação histopatológica deve ser realizada para confirmação diagnóstica.

The present study presents a case report of extraskeletal chondroma or soft tissue chondroma, a rare and benign lesion, diagnosed by clinical findings, imaging studies and histopathological exam. The 24-year-old patient presented at the Orthopedics Section of Unimed Betim Hospital with a slow painless growth on the left thumb about 1 year ago. During the physical examination, a nodular lesion was noted; it had a hard consistency, was mobile and painless, and didn't cause functional impairment for the finger. The patient was referred to the imaging unit of the hospital, where an X-ray was performed; later on, ultrasound and magnetic resonance imaging of the left thumb was done. After the imaging studies, the medical team chose excisional biopsy of the lesion. The histopathological examination confirmed the diagnosis of extra-skeletal chondroma or soft-tissue chondroma. Soft tissue chondroma is usually not considered for a soft-tissue tumor of the hand. Excision is easy and must be complete if recurrences are to be avoided. Histopathological evaluation is required for the final diagnosis.

Results of Abductor Pollicis Longus Suspension Ligamentoplasty for Treatment of Advanced First Carpometacarpal Arthritis

BACKGROUND: Suspension ligamentoplasty using abductor pollicis longus (APL) tendon without bone tunneling, was introduced as one of the techniques for treatment of advanced first carpometacarpal (CMC) arthritis. The purpose of this study was to evaluate the radiologic and clinical results of APL suspension ligamentoplasty. METHODS: The medical records of 19 patients who underwent APL suspension ligamentoplasty for advanced first CMC arthritis between January 2008 and May 2012 were reviewed retrospectively. The study included 13 female and 6 male patients, whose mean age was 62 years (range, 43 to 82 years). For clinical evaluation, we assessed the grip and pinch power, radial and volar abduction angle, thumb adduction (modified Kapandji index), including visual analogue scale (VAS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores. Radiologic evaluation was performed using simple radiographs. RESULTS: The mean follow-up was 36 months (range, 19 to 73.7 months). Mean power improved from 18.3 to 27 kg for grip power, from 2.8 to 3.5 kg for tip pinch, and from 4.3 to 5.4 kg for power pinch. All patients showed decreased VAS from 7.2 to 1.7. Radial abduction improved from 71degrees preoperatively to 82degrees postoperatively. The modified Kapandji index showed improvement from 6 to 7.3, and mean DASH was improved from 41 to 17.8. The height of the space decreased from 10.8 to 7.1 mm. Only one case had a complication involving temporary sensory loss of the first dorsal web space, which resolved spontaneously. CONCLUSIONS: The APL suspension ligamentoplasty for treatment of advanced first CMC arthritis yielded satisfactory functional results.

Duplicação do polegar / Thumb duplication

A polidactilia é a segunda deformidade congênita mais frequente no membro superior, depois da sindactilia. A polidactilia do polegar (pré-axial/radial) geralmente é unilateral e à direita. A classificação mais utilizada é a desenvolvida por Wassel, e desta, o tipo mais frequente é o tipo IV, com duplicação da falange distal e média. A classifi cação de Zuidam é mais completa e inclui outras deformidades, como trifalangismo, hipoplasia e sinfalangismo. O procedimento cirúrgico mais utilizado é a remoção do polegar acessório e reconstrução do polegar, sendo que o grande problema deste procedimento ocorre quando existe instabilidade da articulação metacarpofalangiana e interfalangiana, necessitando de reconstrução dos ligamentos e dos tendões, podendo ser necessária uma osteotomia para corrigir os desvios.

Polydactyly is the second most frequent congenital deformity in the upper limb after syndactily. Polydactyly of the thumb (pre-axial/radial) is usually unilateral and on the right. The most widely used classifi cation is Wassel’s and the most frequent type is type IV, with duplication of the distal and middle phalanx. The classifi cation of Zuidam is more complete and includes such other deformities as triphalangism, hypoplasia and symphalangism. The most common surgical procedure is removal of the accessory thumb and reconstruction of the thumb. The major problem with this procedure arises when there is instability of the metacarpophalangeal and interphalangeal joint, requiring reconstruction of ligaments and tendons, and osteotomy may be needed to correct the deviations.

Conclusiones: El diseño del colgajo permite un mejor avance y profundización del espacio, con un mejor balance entre los flexores y extensores, todos los pacientes tuvieron una mejor función de la extremidad y una mejoría cosmética.

Introduction: Arthrogryposis multiplex congenita is a progressive syndrome characterized by deformed and stiff joints, atrophy or absence of muscles, contracture and thickening of the capsular articular and periarticular tissue, and normal psychic status. Material and methods: A retrospective, descriptive, evidence level III study was conducted on the surgical management of patients with Arthrogryposis multiplex congenita and congenital adducted thumb between January 2005 and December 2010. Twenty-seven opening procedures were performed in 16 patients with a dorsoradial index finger flap technique. In 80% of patients the dominant hand was operated first; patients included nine males and seven females; the operated hands included 15 right and 12 left hands. Results: Flap design permits better advancement and space deepening, and cosmetic improvement. The mean preoperative first and second intermetacarpal angle was 20.5º on average, with a minimum of 14º and a maximum of 27º. The mean postoperative first and second intermetacarpal angle was 50º, with a minimum of 36º and a maximum of 65º. This was observed at the clinic with active thumb extension as well as proper thumb apposition. Conclusions: Flap design permits better advancement and space deepening, with a better balance between flexors and extensors. All patients had better limb function and cosmetic improvement.

Superficial acral fibromyxoma of the thumb: a case report

The authors report a case of superficial acral fibromyxioma (SAF) in a 74-year-old male who presented with a painless mass in a periungual dorsoradial region of the right thumb. It is a rare benign neoplasm, which was recently described, that arouse on the skin and subcutaneous tissue of the hands and feet, especially in the proximity to the ungual region of male adults. Surgical treatment was performed with the excision in blocks of the margins of the lesion and fragmentation of the nail and nail matrix, according to the literature recommendation. Although there may be local recurrence in 22% of the cases, the patient presents no symptoms, deformities or functional limitations. In addition, there was no sign of tumor recurrence 18 months after the surgery. We are not aware of a similar case report in the Brazilian literature.

Diagnóstico precoce e o tratamento cirúrgico do polegar em gatilho congênito na criança utilizando o sistema de internação hospital-dia / Early diagnosis and surgical treatment of congenital trigger thumb in children using the day hospital admission system

Introdução: o polegar em gatilho congênito ou tenossinovite estenosante do polegar é a dificuldade de extensão do polegar, identificada nos primeiros meses de vida. Objetivo: a proposta deste estudo foi discutir o tratamento cirúrgico com os resultados, as complicações e as vantagens na utilização da internação hospital-dia. Método: no período de fevereiro de 2001 até janeiro de 2008, verificaram-se 25 crianças entre 3 meses e 6 anos, portadoras de polegar em gatilho congênito. Foram operadas 35 mãos, e 10 casos eram bilaterais. Observamos que a manifestação clínica quanto à dificuldade de extensão do polegar estava presente em todas as mãos operadas e nenhuma criança queixava-se de dor. As crianças foram submetidas à mesma técnica cirúrgica, anestesia geral inalatória, com incisão transversa na prega volar metacarpofalangeana do polegar acometido e abertura longitudinal da polia flexora A1. Não foi utilizado antibiótico e as crianças foram internadas pelo sistema hospital-dia. Resultados: Quinze crianças eram do sexo masculino e dez do sexo feminino. Dos pacientes com lesão bilateral, sete eram do sexo masculino e três do feminino. Quanto ao lado acometido, obtivemos sete polegares direitos, oito esquerdos e dez bilaterais. Como complicações, não houve nenhuma recidiva; um polegar evoluiu com infecção cutânea superficial e dois polegares apresentaram deiscência parcial da sutura após a retirada dos pontos. Conclusões: o polegar em gatilho congênito ou tenossinovite estenosante do polegar na criança pode ser tratado com segurança através da abertura simples da polia flexora A1, utilizando-se a internação hospital-dia.

The congenital trigger disorder or stenosing tenosynovitis of the thumb is the difficulty of extending the thumb, identified in early months of life. Objective: The purpose this study was to discuss the operative results, complications and advantages of the day hospital system. Method: This study was carried out from February 2001 to January 2008, with 25 children aging from 3 months to 6 years old with congenital trigger finger thumb. Thirty-five hands were submitted to surgery, and ten children had both hands attacked. The limited extension of the thumb was the clinical characteristic observed in all operated hands and no child had pain complaint. All children were submitted to the same surgical technique, by the use of inhalational general anesthetics, with transversal incision in the metacarpophalangeal volar pleat of the thumb and longitudinal resection of the flexor pulley A1. Antibiotic therapy was not used and all children were admitted by the day hospital system. Results: fifteen were boys and ten were girls. Seven boys and three girls had the pathology in both hands. Comparing the incidence of each side, we have found seven right congenital trigger thumbs, eight left and ten occurring in both sides. The complications found were: one thumb had superficial cutaneous infection and two thumbs presented dehiscence of the incision after the removal of the suture. There were no cases of recurrence of the disease after surgery. Conclusion: we concluded that congenital trigger disorder or stenosing tenosynovitis in children can be safely treated with simple incision of flexor pulley A1 and with day hospital system.

Tratamiento de la hipoplasia severa del pulgar con modificación de la técnica de Buck-Gramcko / Treatment of severe hipoplasia of the thumb with modified Buck-Gramcko procedure

La pulgarización del dedo índice mediante la técnica de Buck-Gramcko constituye el tratamiento clásico para la hipoplasia severa y la aplasia del pulgar. En este trabajo se evaluó la eficacia de una modificación aplicada a esta técnica. Se realizó un estudio preliminar en 8 pacientes con diagnóstico de hipoplasia o aplasia del dedo pulgar, atendidos en el Hospital Frank País, en el periodo comprendido entre el 1ro de enero de 2004 hasta el 28 de febrero de 2006. Se realizaron 9 intervenciones quirúrgicas. La posición promedio de abducción palmar fue de 42,22. La posición de reposo promedio en pronación fue de 118,33º. El arco promedio de movimiento en abducción palmar fue de 58,33. El arco de movimiento promedio de pronación logrado por los pacientes fue de 123,33. En 8 (88,9 por ciento) de las 9 manos operadas se logró una oposición del nuevo pulgar con respecto a los demás dedos. En ningún paciente fue necesario realizar una oponoplastia secundaria. En 4 manos el resultado fue excelente, en otras 4 fue bueno y en una fue regular. Esta modificación proporcionó en la mayoría de los pacientes una buena posición del dedo pulgarizado y disminuyó la probabilidad de necesitar una segunda intervención quirúrgica para lograr un resultado satisfactorio.

Pollicization of the index thumb through Buck-Gramcko technique is the classical treatment for aplasia and severe hipoplasia of the thumb. This paper evaluated the efficacy of a modification introduced to Buck-Gramcko procedure. A preliminary study was conducted in 8 patients diagnosed with hipoplasia or aplasia of the thumb and seen at Frank Pais orthopedic hospital from January 1st, 2004 to February 28th 2006. Nine surgeries were performed. The average position of palmar abduction was 42,22. The average rest position in pronation was 118,33. The average movement arc in palmar abduction was 58,33. The average movement arc in pronation reached in patients was 123,33. Eight (88,9por ciento) out of the 9 operated hands succeeded in opposing the new thumb to the rest of the fingers. No patient required a secondary oponoplasty. The outcome was excellent in 4 hands, good in 4 hands and regular in one hand. The introduced modification provided the majority of patients with a good position of the pollicized finger and opposition movement with respect to the rest of the fingers, all of which reduced the possibilities of a second surgery to attain a satisfactory result.

La pollicisation de l'index par la technique de Buck-Gramcko constitue le traitement classique de l'hypoplasie sévère et de l'aplasie du pouce. Dans le présent travail, l'efficacité de cette technique est évaluée. Une étude préliminaire de 8 patients diagnostiqués et traités pour hypoplasie ou aplasie du pouce à l'hôpital ½ Frank Pais ¼ du 1 janvier 2004 au 28 février 2006, a été réalisée. Neuf opérations chirurgicales ont été réalisées. L'abduction palmaire a été de 42.22 en moyenne. La pronation en repos a été de 118.33º en moyenne. La courbe de mouvement en abduction palmaire a été de 58.33 en moyenne. La courbe de mouvement en pronation atteinte par les patients a été de 123.33 en moyenne. Sur 9 mains opérées, 8 (88.9) ont réussi l'opposition du nouveau pouce. Aucun patient n'a eu besoin d'une deuxième opération. Les résultats ont été excellents en 4 mains, bons en 4, et passables en une seule main. La modification de la technique a permis une bonne position et un bon mouvement d'opposition du doigt transplanté, réduisant ainsi le besoin d'une deuxième opération chirurgicale.
