A V-Y shaped flap with digital artery nerve at metacarpophalangeal joint was used to repair the defect of middle and distal phalanx / 中国骨伤

OBJECTIVE@#To explore a surgical method for the reconstruction of volar soft tissue defect and sensory and vascular repair in middle and far phalangeal digits.@*METHODS@#From January 2016 to January 2020, a total of 14 patients , 9 males and 5 females, ages ranging from 22 to 69 years old, and with volar soft tissue defects in the middle and distal digits 2 to 4, underwent surgical reconstruction using the V-Y shaped flap with digital artery and nerve at the metacarpophalangeal joint. The defect area was (2.0~2.5) cm×(1.5 ~2.0) cm. The procedure involved the harvest of a V-Y shaped flap with the digital artery and nerve from the metacarpophalangeal joint. Flap design, dissection of blood vessels and nerves, and anastomosis with the digital artery and nerve were performed according to a standardized protocol., Functional exercise of affected finger was initiated 3 weeks postoperatively. Subsequent assessments were conducted to evaluate finger pulp sensation, shape and other relevant parameters. According to the upper extremity functional evaluation standard set up by Hand Surgery Branch of Chinese Medical Association, the surgical outcomes were evaluated.@*RESULTS@#All 14 cases demonstrated successful tissue transplantation, , with immediate recovery of sensation observed in 10 cases with distal finger pulp defects. Four patients with middle phalangeal defects experienced gradual sensory recovery within 2 to 3 months postoperatively. Thirteen patients were followed up for a mean duration of (8.8 ± 4.49) months, during which satisfactory outcomes were observed. The average two-point resolution of the finger pulp was 4-6mm, and sensory function evaluation yielded a score of S3 or above. Patients exhibited realistic finger shape, normal skin color and temperature, good wear resistance, and cold resistance. Furthermore, finger joint function was essentially normal.@*CONCLUSION@#The V-Y shaped flap with digital artery and nerve at the metacarpophalangeal joint offers a suitable solution for repairing the defect of the middle or distal phalangeal finger. This technique is characterized by its simplicity, low risk, and favorable outcomes, including restored finger shape, blood supply and sensation. Moreover, high patient satisfaction was achieved.

Clinical application of neurovascular staghorn flap for repairing of defects in fingertips / 中国修复重建外科杂志

OBJECTIVE@#To evaluate the effectiveness of neurovascular staghorn flap for repairing defects in fingertips.@*METHODS@#Between August 2019 and October 2021, a total of 15 fingertips defects were repaired with neurovascular staghorn flap. There were 8 males and 7 females with an average age of 44 years (range, 28-65 years). The causes of injury included 8 cases of machine crush injury, 4 cases of heavy object crush injury, and 3 cases of cutting injury. There were 1 case of thumb, 5 cases of index finger, 6 cases of middle finger, 2 cases of ring finger, and 1 case of little finger. There were 12 cases in emergency, and 3 cases with finger tip necrosis after trauma suture. Bone and tendon exposed in all cases. The range of fingertip defect was 1.2 cm×0.8 cm to 1.8 cm×1.5 cm, and the range of skin flap was 2.0 cm×1.5 cm to 2.5 cm×2.0 cm. The donor site was sutured directly.@*RESULTS@#All flaps survived without infection or necrosis, and the incisions healed by first intention. All patients were followed up 6-12 months, with an average of 10 months. At last follow-up, the appearance of the flap was satisfactory, the wear resistance was good, the color was similar to the skin of the finger pulp, and there was no swelling; the two-point discrimination of the flap was 3-5 mm. One patient had linear scar contracture on the palmar side with slight limitation of flexion and extension, which had little effect on the function; the other patients had no obvious scar contracture, good flexion and extension of the fingers, and no dysfunction. The finger function was evaluated according to the total range of motion (TAM) system of the Hand Surgery Society of Chinese Medical Association, and excellent results were obtained in 13 cases and good results in 2 cases.@*CONCLUSION@#The neurovascular staghorn flap is a simple and reliable method to repair fingertip defect. The flap has a good fit with the wound without wasting skin. The appearance and function of the finger are satisfactory after operation.

OBJECTIVE@#To investigate the feasibility and effectiveness of absorbable anchor combined with Kirschner wire fixation in the reconstruction of extension function of old mallet finger.@*METHODS@#Between January 2020 and January 2022, 23 cases of old mallet fingers were treated. There were 17 males and 6 females with an average age of 42 years (range, 18-70 years). The cause of injury included sports impact injury in 12 cases, sprain in 9 cases, and previous cut injury in 2 cases. The affected finger included index finger in 4 cases, middle finger in 5 cases, ring finger in 9 cases, and little finger in 5 cases. There were 18 patients of tendinous mallet fingers (Doyle type Ⅰ), 5 patients were only small bone fragments avulsion (Wehbe type ⅠA). The time from injury to operation was 45-120 days, with an average of 67 days. The patients were treated with Kirschner wire to fix the distal interphalangeal joint in a mild back extension position after joint release. The insertion of extensor tendon was reconstructed and fixed with absorbable anchors. After 6 weeks, the Kirschner wire was removed, and the patients started joint flexion and extension training.@*RESULTS@#The postoperative follow-up ranged from 4 to 24 months (mean, 9 months). The wounds healed by first intention without complications such as skin necrosis, wound infection, and nail deformity. The distal interphalangeal joint was not stiff, the joint space was good, and there was no complication such as pain and osteoarthritis. At last follow-up, according to Crawford function evaluation standard, 12 cases were excellent, 9 cases were good, 2 cases were fair, and the good and excellent rate was 91.3%.@*CONCLUSION@#Absorbable anchor combined with Kirschner wire fixation can be used to reconstruct the extension function of old mallet finger, which has the advantages of simple operation and less complications.

Colgajo libre de primera arteria metatarsiana dorsal para déficit de cobertura en dígito de la mano: reporte de caso clínico / First dorsal metatarsal artery free flap for finger coverage defect: a case report

Las lesiones graves de los dedos con pérdida de sustancia y exposición de estructuras nobles constituyen un desafío para evitar la amputación. Estas situaciones han impulsado el desarrollo de un gran número de colgajos axiales, locales, con el fin de salvar el dígito. Los colgajos libres, tomados a medida, también han sido descritos para dar coberturas adecuadas y de buena calidad. Se presenta el caso de un paciente con lesión grave de dedo anular con exposición ósea y daño tendíneo, con una pérdida de cobertura de 4 4 cm. El paciente fue sometido a una reconstrucción con un colgajo libre del pie, tomando como eje vascular la primera arteria intermetatarsiana. El paciente conservó su dedo con una movilidad a expensas de la articulación interfalángica proximal (IFP), con una piel de buena calidad, pinza firme y sin dolor. La zona dadora no presentó complicaciones. En manos de un equipo entrenado, con indicación adecuada, estos colgajos logran un buen resultado estético y funcional.

Severe finger injuries with loss of substance and exposure of noble structures are a challenge to avoid amputation. These situations have prompted the development of many local axial flaps to save the digit. Customized free flaps have also been described to provide adequate and good-quality coverage. We present the case of a patient with a severe injury to the ring finger with bone exposure and tendinous damage, with a coverage defect of 4 4 cm. The patient underwent reconstruction with a free flap from the foot, taking the first intermetatarsal artery as the donor vascular axis. The patient kept his finger with mobility at the expense of the proximal interphalangeal (PIP) joint, with good-quality skin, firm clamp, and no pain. The donor area did not present complications. In the hands of a trained team, with adequate indication, these flaps achieve a good esthetic and functional result

Reconstrucción en amputaciones distales de dedos en niños con injerto compuesto y vendaje semioclusivo / Reconstruction of distal finger amputations in children with composite autograft and semi-oclusive dressing

La reconstrucción de una amputación distal de dedo en un niño es un desafío. Los procedimientos propuestos son muchos, y los resultados no han sido buenos. La reconstrucción con reposición del segmento a modo de injerto compuesto, o con técnicas microquirúrgicas, parece ofrecer la mejor de las posibilidades, pues se conservan estructuras irremplazables, como el lecho ungueal y el hiponiquio, lo que permite que los niños mantengan un pulpejo anatómico y con función normal. Presentamos una serie de tres pacientes pediátricos tratados con una nueva técnica, que combina la reposición del segmento, como un injerto compuesto, y el uso de curación semioclusiva (composite autograft and semi-oclussive dressing, CASOD, en inglés). Hemos observado buenos resultados.

The reconstruction of finger tip amputation in children is challenging. There are many procedures described to treat this injury, none of which present optimal results. Repositioning of the amputated segment as an autograft or with microsurgical techniques seems to offer the best outcome. It enables the preservation of otherwise irreplaceable structures, such as the nail bed and the hyponychium, thus enabling children to mantain an anatomically and functionally normal finger pad. We present a series of three pediatric patients treated with tha new technique, which combines composite autograft and semi-oclusive dressing (CASOD). The results observed so far have been promising.

Osteosíntesis en fracturas oblicuas o espiroideas largas de metacarpianos: comparación entre tratamiento con tornillos interfragmentarios solos y placa con tornillos / Osteosynthesis in long oblique and spiral metacarpal fractures: Comparison between interfragmentary screws and plating

Objetivos: Comparar el tratamiento de pacientes con fracturas oblicuas o espiroideas largas de metacarpianos, mediante reducción abierta y fijación interna con tornillos interfragmentarios solos o placas y tornillos. Materiales y métodos: Se realizó un estudio retrospectivo comparativo entre 2 grupos de pacientes: uno con 24 pacientes tratados con tornillos interfragmentarios solos y otro con 17 pacientes tratados mediante osteosíntesis con placas y tornillos. En ambos, se utilizó un abordaje longitudinal dorsal, y se les indicó inmovilización posoperatoria con valva de yeso y rehabilitación con el mismo equipo de terapistas ocupacionales. Tras un seguimiento mínimo de 12 meses, se evaluaron los resultados con el puntaje DASH, la movilidad activa total, la distancia pulpejo-palma y la fuerza con dinamometría comparativa. Se consideró significativo un valor p <0,05. Resultados: El tiempo promedio de seguimiento fue de 24.5 meses (rango 12-43).No se hallaron diferencias estadísticamente significativas en el puntaje DASH, la movilidad activa total, la distancia pulpejo-palma y la fuerza. El tiempo hasta el reingreso laboral fue inferior en el grupo tratado con placas y tornillos, aunque se registraron dos casos de retiro de material, sumado, en uno de ellos, a adherencia tendinosa (tenólisis). Conclusiones: El tratamiento de pacientes con fracturas oblicuas o espiroideas largas de metacarpianos, mediante tornillos interfragmentarios solos o placas y tornillos logró resultados similares, se destaca el menor tiempo hasta la reincorporación laboral y la mayor cantidad de complicaciones con placas y tornillos. Nivel de Evidencia: III

Objective: To compare open reduction and internal fixation with interfragmentary screws and with plates and screws for the treatment of long oblique or spiral metacarpal fractures. Materials and methods: A comparative retrospective study was carried out between 2 groups of patients treated surgically. In the first group, 24 patients were treated with interfragmentary screws and in the second group, 17 patients were treated with plate and screw osteosynthesis. A dorsal longitudinal approach was used. Postoperatively, immobilization was performed using a plaster splint; both groups followed rehabilitation with same occupational therapist team. After a minimum follow-up of 12 months, they were evaluated with the DASH score, total active motion (TAM), pulp-to-palm distance, and comparative contralateral dynamometry. A p value < 0.05 was considered significant. Results: The average follow-up was 24.5 months (range 12-43 months). There were no statistically significant differences in DASH, TAM, pulp-to-palm distance, and strength. The group treated with plate and screw fixation returned to work earlier, although there were two cases of implant removal, in addition to tendon adherence (tenolysis) in one of them. Conclusions: The treatment of patients with long oblique or spiral metacarpal fractures with interfragmentary screws or plates and screws showed similar outcomes; the treatment with plate and screws allowed an earlier return to work but had a greater number of complications. Level of Evidence: III

Reparación primaria de los flexores en la zona II. Actualización y técnica quirúrgica / Primary flexor tendon repair in zone II. Update and surgical technique

La reparación primaria de los tendones flexores en la zona II ha sido un desafío desde el surgimiento de la cirugía de la mano como especialidad luego de la Segunda Guerra Mundial. Desde Bunnell hasta hoy, la forma de operar y rehabilitar estos tendones ha evolucionado y cambiado considerablemente gracias a estudios anatómicos, biológicos y, sobre todo, mecánicos. Actualmente la técnica quirúrgica se basa en realizar una sutura fuerte y prolija, que no sufra fricción dentro de la vaina y que tolere la carga necesaria para la movilidad activa del dígito sin resistencia. Se han descrito múltiples configuraciones de puntos con diferentes materiales. Operando con anestesia local, la prueba de flexo-extensión activa intraoperatoria revela la resistencia del tipo de sutura elegida y ha cobrado importancia para definir el protocolo de rehabilitación. El tratamiento de los flexores en la zona II es, hasta el momento, un conjunto inseparable de técnica quirúrgica y rehabilitación asociada. La manipulación farmacológica del proceso biológico reparador es el principal campo de investigación actual

Primary flexor tendon repair in zone II has been a challenge since the emergence of hand surgery as a specialty after World War II. From Bunnell to today, the way of operating and rehabilitating these tendons has evolved and changed considerably thanks to anatomical, biological and --above all --mechanical studies. Currently, the surgical technique is based on performing a strong and neat suture, which does not suffer friction within the sheath and which tolerates the load necessary for the active motion of the finger without resistance. Multiple suture configurations with different materials have been described. Under local anesthesia, the intraoperative active flexion-extension test reveals the resistance of the type of suture chosen and has gained importance in defining the rehabilitation protocol. Treatment of flexors in zone II is, so far, an inseparable set of surgical technique and a suitable rehabilitation protocol. Biological strategies to enhance the tendon healing process are currently the main field of research

Reimplante de falange distal de dedo sin anastomosis venosa con anestesia local / Distal phalanx replantation under local anesthesia and without venous anastomosis

Presentamos a un paciente que sufrió una amputación traumática de la falange distal del 5to dedo de su mano izquierda, y fue tratado mediante un reimplante sin anastomosis venosa. En el mismo acto quirúrgico, se le realizó una artrodesis definitiva con clavijas. La cirugía se efectuó con anestesia troncular del dedo, por lo cual no se requirió de un anestesista ni fue necesario un tiempo adecuado de ayuno. Debido a la localización distal de la amputación y a la ausencia de una vena dorsal viable para ser anastomosada, se optó por un drenaje venoso controlado mediante la extracción de la placa ungueal, el frotado del lecho ungueal y la colocación periódica (cada 3 h, por 7 días) de una gasa impregnada con heparina. Además, el paciente fue anticoagulado con enoxaparina 40 mg y ácido acetilsalicílico cada 24 h, por 21 días. El reimplante fue exitoso. Nivel de Evidencia: IV

We present a patient who experienced a traumatic amputation of his left fifth finger distal phalanx, and was treated using replantation without venous anastomosis. The same surgical procedure also included a final arthrodesis with Kirschner wires. Surgery was performed with digital block anesthesia, which did not require the presence of an anesthesiologist nor fasting. The distal level of the amputation and the lack of viable options for dorsal vein anastomosis motivated our decision for venous drainage controlled by nail-plate removal, nail-bed scrubbing and periodic (every 3 hours during 7 days) dressing with heparin-impregnated gauze. In addition, the patient received anticoagulant therapy with aspirin and enoxaparin 40 mg every 24 hours for 21 days. The replantation procedure was a success. Level of Evidence: IV

Colocación de un tornillo transfisario medial en la cadera espástica de niños con parálisis cerebral. Eficacia y seguridad / Medial transphyseal screw placement for spastic hip treatment in children with cerebral palsy. Effectiveness and safety

Introducción: En estudios experimentales y clínicos, los resultados con el tornillo excéntrico transfisario medial para producir varo fueron alentadores. El propósito de este estudio fue determinar si colocar un tornillo en el fémur proximal es un gesto eficaz y seguro en caderas espásticas de niños con parálisis cerebral. Materiales y Métodos: Se incluyó a pacientes con parálisis cerebral infantil y caderas en riesgo. Se compararon la serie A: pacientes con liberación de partes blandas más colocación de un tornillo excéntrico transfisario medial en el fémur proximal y la serie B: pacientes solo con liberación de partes blandas. Se determinaron el test de Rang, el índice de migración de Reimer, el ángulo cervicodiafisario y las complicaciones, antes de la cirugía y después. Resultados: Se operó a 18 pacientes (36 caderas): 10 de la serie A y 8 de la serie B, con una mediana de edad de 51 meses y una mediana de seguimiento, de 3 años. Al comparar por delta de medianas todas las variables preoperatorias y posoperatorias, hubo una diferencia estadísticamente significativa solo en el delta de mediana del ángulo cervicodiafisario de las caderas izquierdas (-5 vs. 0, p 0,02). Conclusiones: La liberación de partes blandas es eficaz para prevenir la luxación de la cadera espástica. La colocación de un tornillo transfisario excéntrico en la cadera espástica no produjo cambios y no fue inocua. La hemifisiodesis medial de la cadera es una atractiva solución teórica para tratar los problemas ocasionados por el valgo excesivo, pero se requieren más estudios. Nivel de Evidencia: III

Introduction: Animal and clinical studies have shown promising results for the varus-producing placement of a medial eccentric transphyseal screw. The purpose of this study was to establish if the placement of a screw in the proximal femur is an effective and safe approach for spastic hips in children with cerebral palsy (CP). Materials and Methods: We compared two series of pediatric CP patients (Gross Motor Function Classification System [GMFCS] III, IV and V) with "hips at risk." Series A patients were treated with soft-tissue release plus a medial eccentric transphyseal screw in the proximal femur. Series B patients were only treated with soft-tissue release. Patients were evaluated pre and postoperatively to determine their Rang test score, Reimer's migration index (MI), diaphyseal cervical angle, and complications. Results: From a total of 18 patients operated, 36 hips, 55% (10) belonged to the A Series and 45% (8) to the B Series. The median age was 51 months (IQR, 41-108). The median follow-up was 3 years (IQR, 2.4-5.8). The comparative analysis of all preoperative and postoperative variables yield only one statistically significant difference: the median left hip diaphyseal cervical angle (-5 vs. 0, P 0.02). Conclusions: The release of soft tissues was effective to prevent the spastic hip dislocation. The placement of medial eccentric transphyseal screw in spastic hips produced some complications and no beneficial changes. Medial hemiphysiodesis of the hip remains nothing but an attractive theoretical solution for the treatment of problems caused by excessive valgus. However, further studies are warranted.

Triple open dislocation in the index finger of the hand without a high-energy trauma / Triple luxación abierta del segundo dedo de la mano tras traumatismo de baja energía

A simultaneous double dislocation (both proximal [PIP] and distal [DIP] interphalangeal joints) of a triphalangeal finger is a rare entity. The most common hand affected is the right hand. In the case of a closed triple dislocation (metacarpophalangeal [MCP], PIP and DIP joints); there are only two cases in the literature revised. In this case, we report an open triple dislocation in the index finger of the left-hand of a 54-year-old man treated by closed reduction and 3 weeks of immobilization followed by active mobilization with satisfactory results.

La luxación simultánea de las articulaciones interfalángicas proximal (IFP) y distal (IFD) de un dedo de tres articulaciones es una rara entidad. La mano que es afectada con más frecuencia es la derecha. Con relación a una triple luxación cerrada (articulación metacarpofalángica [MCF], IFP e IFD), sólo hay descritos dos casos en la literatura revisada. En este caso, describimos una triple luxación abierta del segundo dedo de la mano en un varón de 54 años de edad tratada mediante reducción cerrada,e inmovilización durante 3 semanas seguida de movilización activa supervisada, con resultado final satisfactorio.

Preliminary study on functional and aesthetic reconstruction by using a small artery-only free medial flap of the second toe for fingertip injuries

OBJECTIVES: This study was designed to introduce the feasibility of fingertip reconstruction by using a free medial flap of the second toe without vein anastomosis. METHODS: In total, 8 patients with fingertip injuries were treated successfully with this method. Patients who underwent reconstruction from September 2016 to October 2017 in our hospital with an artery-only free medial flap transfer of the second toe for fingertip injuries were included, and patients who underwent additional procedures that may impact the postoperative results and were followed up for less than 6 months were excluded. Clinical trial registration: ChiCTR19000021883. RESULTS: According to the Allen classification, five patients had Type 3 injuries, and three patients had Type 4 injuries. One arterial nerve and one digital nerve were repaired at the same time. No additional dissection was performed in either the donor or recipient site of the dorsal or volar vein. Postoperative venous congestion was monitored based on the color, temperature and the degree of tissue oxygen saturation. The flap size ranged from 1.20*1.0 cm2 to 1.80*1.0 cm2. The reconstruction time was 71.86 (SD 14.75) minutes. The two-point discrimination and the monofilament results were satisfying; cold intolerance did not appear in five patients, and the other three patients had cold intolerance with grades of 4, 12 and 26, which were considered satisfactory. Moreover, leech therapy, continuous bleeding and needle sutures were not utilized in any cases. CONCLUSIONS: Reconstruction with a small artery-only free medial flap transfer of the second toe led to satisfactory sensory and motor function in the selected patients with fingertip injuries.

Repair of soft tissue defects of the fingers with medial plantar venous flap

SUMMARY OBJECTIVE To report the surgical procedures and efficacy of using medial plantar venous flap for the repair of soft tissue defects of the fingers. Methods From March 2010 to April 2012, medial plantar venous flaps were harvested to repair the wounds of 31 fingers in 29 cases. Among them, there were 13 middle fingers with defects at the tips in 11 cases, 7 fingers with defects in the dorsal part in 7 cases, and 11 fingers with defects in the finger pulp in 11 cases. The size of the defects ranged from 1.2cm×1.5 cm to 2.5cm × 3.5cm. Medial plantar venous flaps of 1.5cm × 2cm - 3×4 cm were harvested. Full-thickness skin grafts were adopted for the donor areas. RESULTS All 31 flaps survived, except for 1 flap with arterial crisis and 2 cases with venous crisis. These conditions were timely corrected by secondary anastomosis of artery and vein and the flaps survived. The wounds and the donor areas achieved healing by the first intention. All grafted skins survived. Postoperative follow-up was conducted for 26 fingers in 24 cases for 4-12 months, excluding 5 cases with lost follow-up. The dorsal part of the damaged fingers had normal morphology, and the skin color and texture were similar to those of the normal skin. After the repair of defects in the fingertip and pulp, fingerprints appeared, and the protective sensation was restored. CONCLUSION The soft tissue defects of the fingers can be satisfactorily repaired with medial plantar venous flap, and little damage is caused to the donor area. This method is proven effective for the repair of soft tissue defects of the fingers.

Second toe-to-hand transplantation.: A surgical option for hand amputations / Trasplante del segundo dedo del pie a la mano.: Una opción quirúrgica para las amputaciones en la mano

Background: The toe to hand transplantation is a method of reconstruction on the unique or multiple amputations of the fingers. It can be used the whole toe or with certain modifications as a wrap-around flap from the big toe or fingertip. It is a widely accepted option for the thumb. Methods: It is a series of patients with amputation of one or more fingers of the hand were operated with second toe to hand transplantation. The survival was evaluated and the sensory recovery by 2-point discrimination. Results: We practiced 12 transplants, 8 thumb, and 4 in other fingers. Ten were adults and two children. All transplants survived. Two patients required tenolysis flexor. The sensibility was recovered with good 2-point discrimination of 8 mm. Discussion: In the more proximal finger amputations, a second toe is the most appropriate, with lower morbidity of the donor site. The rates of success are between 95 to 100%. We had a success rate of 100%. The resulting defect is in the foot is minimum when the second toe was used. The decision to use one of these techniques depends on the decision and transplant surgeon training. We always used the second toe for transfers to the hand, considering that it will be thinner than the original thumb; our patients had no complaint about the appearance. Conclusion: Toe-to-hand transplantation is a good technique, providing a very good aesthetic appearance and allowing the recovery of sensitivity. The defect that is created in the foot does not produce significant aesthetic and functional alterations.

Antecedentes: El trasplante de un dedo del pie a la mano es un método de reconstrucción en las amputaciones únicas o múltiples de los dedos. Se puede usar el dedo en su totalidad o con ciertas modificaciones como una envoltura de piel y uña, o de la punta del dedo. Es una opción ampliamente aceptada para el pulgar. Métodos: Es una serie de pacientes con amputación de uno o más dedos de la mano, intervenidos con un trasplante del segundo dedo del pie a la mano. Se evaluó la supervivencia del trasplante y la recuperación sensitiva con la discriminación de 2 puntos. Resultados: Se realizaron 12 trasplantes, 8 para el pulgar, y cuatro en otros dedos de la mano. Diez fueron adultos y 2 niños. Todos los trasplantes sobrevivieron. Dos pacientes requirieron tenolisis del flexor. La sensibilidad recuperada fue buena con discriminación de 2 puntos de 8 mm. Discusión: En las amputaciones más proximales de los dedos, un segundo dedo del pie es el más adecuado, con menor morbilidad de la zona donante. La tasa de éxito está entre el 95 a 100%. Nosotros tuvimos un 100%. El defecto resultante en el pie es mínimo cuando se usa el segundo dedo. La decisión de utilizar una de las técnicas de trasplante depende de la decisión y formación del cirujano. Conclusión: Es una buena técnica que brinda una apariencia estética muy buena y permite la recuperación de la sensibilidad. El defecto resultante en el pie no produce alteraciones funcionales ni estéticas significativas.

Reintegração de amputação digital distal com enxerto composto e difusão plasmática ampliada distal no plano dérmico palmar - relato de um caso em criança de 2 anos de idade e revisão da literatura / Reintegration of distal digital amputation with composite graft and plasmatic diffusion expanded distally on the palmar dermal plane - a case report of a 2-year-old child and a literature review

Nas amputações mais distais da ponta dos dedos, o reimplante microcirúrgico pode não ser praticável. Nestes casos, o enxerto composto oferece os melhores resultados funcionais e estéticos, sendo, porém, incerta a sua reintegração. Várias técnicas foram aventadas para melhorar a sobrevida do enxerto volumoso, basicamente diminuindo o seu volume, associando ou não um retalho cutâneo. Outras técnicas criam uma superfície adicional de contato para difusão plasmática, o "bolso subcutâneo", sem diminuir o volume do enxerto composto, com altas taxas de sucesso. O presente artigo apresenta um caso de amputação da ponta distal do dedo mínimo (zona I de Ishikawa) numa criança de 2 anos de idade. Impossível de reimplante microcirúrgico, a reintegração foi feita com enxerto composto do coto amputado, sem desbridamento, e com a criação de uma nova superfície de contato para difusão plasmática, na extremidade distal do coto enxertado, no plano dérmico da região hipotênar, aumentando assim a área de contato e diminuindo a distância radial da difusão plasmática no enxerto composto. Doze dias após, esse contato adicional foi separado e ambas as superfícies apresentaram sangramento. A reintegração foi total, com mínimas cicatrizes no dedo e na região hipotênar. Uma breve revisão bibliográfica foi feita e discutidos os conceitos cirúrgicos, assim como os fatores que influenciam na sobrevida do enxerto composto.

In more-distal amputations of the fingertips, microsurgical replantation is not feasible. For these cases, composite graft provides the best functional and aesthetic results. However, its reintegration is uncertain. Several techniques have been proposed to improve bulky graft survival by basically reducing its volume, regardless of whether a skin flap is connected. Other techniques create an additional contact surface for plasmatic diffusion, the so-called subcutaneous pocket, without reducing the composite graft volume and yielding high success rates. This article presents a case of amputation of the distal tip of the fifth digit (Ishikawa zone I) of a 2-year-old child. Because of the impossibility of microsurgical replantation, a composite graft was used to reintegrate the amputated stump, without debridement, by creating a new contact surface for plasmatic diffusion at the distal end of the grafted stump, on the dermal plane in the hypothenar region, thereby increasing the contact area and decreasing the radial distance for the plasmatic diffusion of the composite graft. Twelve days later, the additional contact was separated and both surfaces presented bleeding. Full reintegration occurred with minimal scarring of the finger and hypothenar region. A brief literature review was conducted, discussing surgical concepts and factors that influence composite graft survival. The most appropriate and best vascularized anatomic plane for additional contact with the graft in the recipient area needs to be determined.

Fibromatose digital infantil: relato de caso / Infantile digital fibromatosis: case report

Introdução: A fibromatose digital infantil é uma proliferação nodular, assintomática, rara e benigna do tecido fibroso, que ocorre quase exclusivamente na região dorsal e lateral dos dedos das mãos e pés. O artigo relata um caso de fibromatose digital infantil, também conhecida como tumor de Reye. Relato de Caso: Trata-se de um caso diagnosticado por meio de exames clínico, de imagem e histopatológico. O paciente apresentou-se ao Setor de Ortopedia do Hospital, queixando-se de uma lesão nodular, eritematosa, indolor, no segundo pododáctilo do pé esquerdo, existente havia quatro anos. Durante o exame físico, notava-se uma deformidade no II pododáctilo, causada por uma lesão nodular, eritematosa, indolor, de aproximadamente 1,5 cm, que não acarretava alterações funcionais. O exame de ultrassom revelou a presença de uma imagem nodular sólida, hipoecogênica, envolvendo o tendão do extensor do II pododáctilo na falange média. O diagnóstico inicial era de fibroma ou sinovioma. Pelas características clínicas da lesão, por seu tempo de evolução e pelos achados de imagem, a equipe optou por uma biópsia. No entanto, devido ao pequeno tamanho da lesão, sendo a biópsia aberta, realizou-se a exérese cirúrgica. O exame histopatológico confirmou o diagnóstico de fibromatose digital infantil. Conclusão: Esse tumor constitui uma entidade clínica rara, que deve ser diferenciada de outras lesões encontradas nos dedos das mãos e dos pés. O diagnóstico correto raramente é feito antes da operação, devido, principalmente, à falha em reconhecer essa entidade. Por essa razão, é essencial considerar essa lesão em diagnósticos diferenciais.

Introduction: Infantile digital fibromatosis, also known as Reye tumor, is a rare, asymptomatic, benign nodular proliferation of fibrous tissue, which occurs almost exclusively in the dorsolateral region of the fingers and toes. This article reports a case of infantile digital fibromatosis. Case report: This case was diagnosed by clinical, imaging, and histopathological examination. The patient presented at the rthopedic Department of our hospital, with a 4-year history of a painless, erythematous nodular lesion on the econd toe of the left foot. On physical examination, a deformity of the second toe caused by a nodular, erythematous, painless lesion of approximately 1.5 cm diameter was noted; the lesion did not result in functional changes. Ultrasound examination revealed a solid, hypoechoic nodule involving the extensor tendon in the middle phalanx of the second toe. The initial diagnosis was fibroma or synovioma. Due to the clinical characteristics of the lesion, its evolution, and the imaging findings, the team chose to perform a biopsy. However, due to the small size of the lesion, upon open biopsy, surgical excision was performed. Histopathological examination confirmed the diagnosis of infantile digital fibromatosis. Conclusion: Infantile digital fibromatosis is a rare clinical entity, which should be differentiated from other lesions found in the fingers and toes. The correct diagnosis is rarely made pre-operatively, due mainly to a failure to recognize this entity. For this reason, it is essential to onsider this lesion in the differential diagnosis of digital nodules.

The Ishiguro Technique for the Treatment of Mallet Finger Fracture.

The results of Ishiguro Technique for the treatment of mallet fractures of the distal phalanx were assessed in 31 consecutive patients. The indication for operation was a displaced mallet finger fracture involving more than onethird of the articular surface, with or without volar subluxation of the distal phalanx and in those patients where fracture reduction was not proper after application of mallet finger splint. According to the Crawford’s rating system there were 19 excellent, 7 good, 4 fair and one poor results. We believe that this technique, when properly applied, produces satisfactory results.
