RESUMEN
Objective: To explore the mechanism, surgical method, and effectiveness of proximal phalangeal bone avulsion fracture caused by A2 circular trochlea injury of the flexor digitorum tendon. Methods: A retrospective analysis was conducted on the clinical data of 4 patients with proximal phalangeal bone avulsion fracture caused by A2 circular trochlea injury of flexor digitorum tendon admitted between May 2018 and September 2022. The patients were all male, the age ranged from 26 to 52 years, with an average of 33 years. The injured fingers included 1 case of middle finger and 3 cases of ring finger. The causes of injury were rock climbing of 2 cases and carrying heavy objects of 2 cases. Preoperative anteroposterior and lateral X-ray films and CT examination of the fingers showed a lateral avulsion fracture of the proximal phalanx, with a fracture block length of 15-22 mm and a width of 3-5 mm. The total active range of motion (TAM) of the injured finger before operation was (148.75±10.11)°. The grip strength of the middle and ring fingers was (15.50±2.88) kg, which was significantly lower than that of the healthy side (50.50±7.93) kg ( t=-8.280, P<0.001). The time from injury to operation was 2-7 days, with an average of 3.5 days. One Kirschner wire with a diameter of 1.0 mm was used for direct fixation through the fracture block, while two Kirschner wires with a diameter of 1.0 mm were used for compression fixation against the fracture block. The fracture healing was observed, and the TAM of the injured finger and the grip strength of the middle and ring fingers were measured. The finger function was evaluated according to the upper limb functional assessment trial standards of the Chinese Medical Association Hand Surgery Society. Results: The incisions all healed by first intention after operation. All patients were followed up 6-28 months, with an average of 19 months. X-ray films showed that all avulsion fractures of proximal phalanx reached bony union, and the healing time ranged from 4 to 8 weeks, with an average of 4.6 weeks. At last follow-up, the grip strength of the middle and ring fingers was (50.50±7.76) kg, which significantly improved when compared with preoperative one ( t=-8.440, P<0.001). The TAM of the injured finger reached (265.50±2.08)°, and there was a significant difference when compared with preoperative one ( t=-21.235, P<0.001). According to the upper limb functional assessment trial standards of the Chinese Medical Association Hand Surgery Society, the finger function was all evaluated as excellent in 4 cases. Conclusion: Using Kirschner wire fixation through bone blocks and external compression fixation of bone blocks for treating proximal phalangeal bone avulsion fracture caused by A2 circular trochlear injury of the flexor digitorum tendon can achieve good effectiveness.

BACKGROUND: Bony defects in finger injuries and infections impose high demands on their treatment due to the close anatomic relationships. Ideally, the injuries are entirely treated in emergency care. Due to the mechanism of the accident, contaminated and compromised soft tissues are often present and set limits to single-stage treatment. We present the long-term subjective and functional results after two-stage reconstruction of bony finger joint defect injuries. PATIENTS AND METHODS: Over a period of 15 years, a total of 40 patients with 43 fingers were treated due to a defect injury in the phalanges. Initially, the finger was stabilised with Kirschner wires after debridement. After consolidation of the soft tissue, the bone was reconstructed in a subsequent operation by interposition of an iliac crest graft. Complications occurred in 9 patients. Twenty-five patients with 27 fingers were followed up for 10.3 years. Range of motion, length of the affected finger, and grip force, each in relation to the contralateral extremity, were recorded. In addition to a subjective assessment of the global result, the daily function was determined by means of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS: Significant differences compared with the contralateral extremity (p<0.05) were found in length (70 mm; 91.0%) and total mobility of the affected finger (95°; 46.0%), hand span when the thumb was involved (202.5 mm; 93.4%), and power grip when one of the fingers was injured (30 kg; 84.1%). The DASH score was 4.2 points (0-55.8). Subjectively, 88% of patients were satisfied with the treatment outcome. CONCLUSION: In case of contaminated and compromised soft tissues, the two-stage treatment of bony defect injuries in finger joints by arthrodesis of the joint is a reliable treatment strategy. In the long run, it results in a very satisfactory function of the hand in everyday life although significant differences have been measured compared with the contralateral extremity.

Congenital dorsal curvature of the distal phalanx has been previously described as 'reverse Kirner' or 'ski-jump' deformity. This report describes bilateral occurrence in the thumbs. A 13-year-old male presented with difficulty caring for his thumbnails and in picking up small objects. Examination showed dorsal curvature of the distal phalanges of both thumbs, with greater curvature of the right side. Radiographs showed wedge-shaped epiphyses and dorsal curvature without coronal plane deviation of the distal phalanges. There was objective and subjective decrease in function associated with lateral pinch and tripod grasp. The reported aetiopathogenesis for Kirner deformity cannot explain the observed dorsal curvature. The bilateral nature makes a secondary physeal cause unlikely and suggests an embryologic basis. Due to the noticeable deficits in function, operative intervention may be warranted. Level of Evidence: Level V (Therapeutic).

OBJECTIVES: This study aims to present long-term follow-up results of the reverse dorsolateral proximal phalangeal island flap designed for reconstruction of large fingertip and pulp defects. METHODS: We examined 18 patients who underwent reverse dorsolateral proximal phalangeal island flap surgery to address ≥2.5 cm fingertip and pulp defects. Mean follow-up was 84.4 months. Sensitivity assessments were conducted using the Semmes-Weinstein monofilament and 2-point discrimination tests. Additionally, we evaluated finger joint active range of motion, complications and cold intolerance. RESULTS: Mild venous congestion was observed in 5 flaps. Significant differences were observed in 2-point discrimination and Semmes-Weinstein monofilament tests between the injured and contralateral sides, specifically in the flaps, the dorsal side of the middle phalanx, and the donor site. The flap's mean static 2-point discrimination was 8.3 mm. Restricted distal interphalangeal joint extension was observed in 2 cases. Total active motion with the flap was good or excellent in the injured fingers, but with a significant difference between injured and contralateral fingers. Additionally, 42% of the injured fingers exhibited hook nail deformity, and 2 patients reported cold intolerance. Despite these issues, most patients has high scores for the appearance and satisfaction aspects of the Michigan Hand Outcomes Questionnaire. CONCLUSION: In moderate or larger fingertip defects, the reverse dorsolateral proximal phalangeal island flap serves as an alternative for reconstructing both fingertip and pulp issues. However, this option involves sacrificing some sensation in the dorsum of the middle phalangeal finger and the donor area. LEVEL OF EVIDENCE: IV, therapeutic study.

INTRODUCTION: Phalangeal fractures are the most common fractures of the hand and in particular the proximal phalanx of the long fingers is the most involved. These fractures can ben conservatively managed but, when the fracture pattern is considered unstable, surgical treatment is recommended. However, there is no consensus in literature about the proper surgical option for extra-articular proximal phalanx fractures. MATERIAL AND METHODS: We compared clinical and radiographical results after treatment of 75 cases of extra-articular proximal phalanx fractures using three different surgical techniques: closed reduction and internal fixation (CRIF) with Kirschner wires (G1 group), open reduction internal fixation (ORIF) with plates and screws or lag screws (G2 group), and closed reduction and intramedullary screw fixation (CRIMEF)(G3 group). RESULTS: We found no significant differences in term of union rate and time to fracture healing between the three groups. However, we found a significant reduction in time to return at work and in TAM at the final follow-up examination in G3 group (treated with CRIMEF) when compared with both G1 and G2. No differences in complications rate were found between three groups. DISCUSSION: The surgical variability in the management of extra-articular phalanx fractures create lacks on standard guide for treatment. CONCLUSIONS: In conclusion, our results showed good clinical and radiographical results with all the three surgical options. However, the closed reduction and internal fixation with intramedullary screws (CRIMEF) seems to be better in terms of time to return to work and TAM at the final follow-up, probably due to good primary stability and little risk of soft tissue adherence development.

PURPOSE: To compare the outcomes of type II pediatric phalangeal neck fractures (PPNFs) treated with closed reduction and cast immobilization (CRCI) versus closed reduction percutaneous pinning (CRPP), and evaluated the clinical efficacy of conservative versus surgical treatment of type II PPNFs via meta-analysis. METHODS: Patients aged ≤ 14 years with type II PPNFs were divided into conservative (CRCI) and operative (CRPP) groups. Radiographs measured angulation and translation; hand function was assessed with total active range of motion (TAM) and Quick-DASH. Complication rates were also compared between the groups. A meta-analysis of conservative versus operative treatment confirmed the clinical results. Statistical analysis was performed using SPSS 26.0 and R studio 3.0 with two-tailed, chi-squared, and Mann-Whitney U or t-tests, P < 0.05. Meta-analysis used fixed or random effects models, calculating mean differences and odds ratios for outcomes, and assessing heterogeneity with I2 and Q tests. RESULTS: Final angulation (3.4° ± 3.7° and 4.9° ± 5.4° vs. 3.6° ± 3.7° and 4.2° ± 4.3°) and displacement (6.3% ± 5.8% and 5.7% ± 4.7% vs. 5.8% ± 5.5% and 3.2% ± 4.2%) in the coronal and sagittal planes were not different statistically between the conservative and surgical groups (P > 0.05), but improved significantly compared to preoperative values (P < 0.05). Although Quick-DASH scores were comparable in both groups (P = 0.105), conservatively treated patients had a significantly better TAM at the last follow-up visit (P = 0.005). The complication rates were 24.2% and 41.7% in the surgical and conservatively treated groups respectively (P = 0.162). However, the latter primarily experienced imaging-related complications, whereas the former experienced functional complications (P = 0.046). Our meta-analysis (n = 181 patients) also showed comparable functional (P = 0.49) and radiographic (P = 0.59) outcomes and complication rates (P = 0.21) between the surgical (94 patients) and conservative (87 patients) groups. CONCLUSIONS: Conservative and surgical treatments are both reliable and safe approaches for managing type II PPNF in children. However, conservatively treated patients generally experience similar radiographic outcomes, lower complication rates, and better functional outcomes than surgically treated ones.

A 32 year-old climber sustained a grade IV frostbite injury to the right hand which required amputation at the neck of the proximal phalanges of all the long fingers. To increase range of motion and strength in the remaining metacarpophalangeal joints, tenodesis of the flexor digitalis superficialis and profundus tendons onto the proximal phalanges was performed. Several revisions for removal of bony spurs, dorsal skin advancement flaps and web space deepening were necessary. After 2 years, the patient achieved 10-0-100° metacarpophalangeal joint range of motion in extension-flexion and could do full body-weight pull-ups on 1 cm deep holds, lift 50 kg on a 2 cm deep hold (normal contralateral side, 40 kg), climb up to F7a routes and use a mechanical 4-finger functional prosthesis.

Phalangeal fractures are extremely common in the pediatric and adolescent populations. The incidence of phalangeal fractures peaks in children ages 10 to 14 years, corresponding to the age in which children begin contact sports. Younger children are more likely to experience crush injuries, whereas older children often sustain phalangeal fractures during sports. The physis is particularly susceptible to fracture because of the biomechanically weak nature of the physis compared with the surrounding ligaments and bone. Phalangeal fractures are identified through a thorough physical examination and are subsequently confirmed with radiographic evaluation. Management of pediatric phalangeal fractures is dependent on the age of the child, the severity of the injury, and the degree of fracture displacement. Nondisplaced fractures are often managed nonsurgically with immobilization, whereas unstable, displaced fractures may require surgery, which is often a closed rather than open reduction and percutaneous pinning.

Antecedentes y objetivo: Las fracturas de falange proximal (FP) son las fracturas más frecuentes de la mano. En los últimos años, se ha descrito el uso de tornillos endomedulares sin cabeza (TESC) para las fracturas inestables transversas u oblicuas de la FP. A pesar de que tanto la técnica anterógrada como retrógrada con TESC han mostrado buenos resultados, no se ha publicado ningún estudio comparativo de su uso en fracturas de FP. Nuestro objetivo es determinar la estabilidad que se obtiene con el uso de TESC retrógrados y anterógrados en un modelo en cadáver de fractura transversa proximal de FP, a dos niveles diferentes. Material y métodos: Realizamos un estudio biomecánico en 30 modelos de fractura de FP de cadáver fresco-congelado. La osteotomía se realizó a los 9 mm desde la articulación metacarpofalángica (MCF) en 15 especímenes, y a una distancia de 15 mm en los otros 15. A su vez, en cada grupo, cinco osteotomías se estabilizaron con un TESC anterógrado intraarticular, cinco mediante un TESC anterógrado transarticular y cinco con un TESC retrógrado. Resultados: La fijación con TESC anterógrado en osteotomías realizadas a los 9 mm (tanto con la técnica transarticular como intraarticular, 62,74 N y 70,86 N, respectivamente) fue más estable que la fijación con TESC retrógrado (32,72 N) (p 0,022). Por otra parte, la fijación con TESC retrógrado fue más estable en el modelo de fractura más distal (90,52 N retrógrado vs. 57,64 N transarticular vs. 42,92 N intraarticular (p = 0,20). Conclusiones: La fijación con TESC retrógrado ofrece más estabilidad en fracturas más distales, mientras que las técnicas anterógradas son más estables en fracturas proximales.(AU)
Background and objective: Phalangeal fractures are the most common hand fractures. In the last years, intramedullary compression screw (IMHCS) for instable transverse or short oblique proximal P1 fractures have been described. Although both anterograde (intraarticular or trans-articular) and retrograde IMHCS techniques have shown good results, no comparison between anterograde and retrograde screw in P1 fractures has been published. We sought to determine stability with retrograde IMHCS and anterograde IMHCS, both trans-articular and intra-articular technique, in a cadaveric transverse proximal P1 fracture model, at two different levels. Material and methods: We performed a biomechanical study in 30 fresh-frozen human cadaveric P1 fracture model. Fracture was performed at 9-mm from the metacarpo-phalangeal (MCP) joint in 15 specimens, whereas it was done at 15 mm in the other 15. In turn, in each group, five fractures were stabilized with an anterograde intra-articular IMHCS, five with anterograde trans-articular IMHCS and other five with retrograde IMHCS. Results: Anterograde IMHCS fixation in 9-mm P1 fractures (both trans- and intra-articular technique, 62.74 N and 70.86 N, respectively) was found to be more stable than retrograde IMHCS one (32.72 N) (p = 0.022). Otherwise, retrograde IMHCS fixation was found to be more stable in more distal P1 fractures (90.52 N retrograde vs. 57.64 N trans-articular vs. 42.92 N intra-articular; p = 0.20). Conclusions: Anterograde IMHCS fixation in proximal transverse P1 bone cut in a cadaveric model provides more stability than retrograde IMHCS, while retrograde screw provides more stability when the bone cut is located more distal.(AU)

Introducción: El osteoma osteoide de falange es un cuadro infrecuente. El objetivo de este artículo es presentar cinco pacientes con diagnóstico histopatológico de osteoma osteoide de falange y resaltar los aspectos más relevantes del diagnóstico y el tratamiento. Materiales y Métodos: Estudio descriptivo, retrospectivo. Se evaluaron el dolor, según la escala analógica visual, la movilidad activa y el puntaje QuickDASH antes de la cirugía y en el control final a los 35.4 meses. Resultados: El tiempo medio desde la primera consulta hasta el diagnóstico fue de 10.6 meses (rango 5-16). El puntaje QuickDASH medio preoperatorio fue de 22,72 (rango 6,8-40,9). Luego del seguimiento medio de 35.4 meses (rango 17-63), todos los pacientes estaban satisfechos con el resultado. El puntaje medio de dolor fue 0. El puntaje QuickDASH medio fue 0. Conclusiones: El osteoma osteoide debe pensarse como diagnóstico diferencial ante un paciente que consulta por dolor digital subagudo o crónico que cede con antinflamatorios no esteroides. El tratamiento quirúrgico mediante el curetaje simple o la resección en bloque logra resultados satisfactorios. Sin embargo, como su prevalencia es baja, se suele pasar por alto y así se retrasan el diagnóstico y el tratamiento. Nivel de Evidencia; IV
Introduction: Osteoid osteomas are rarely found in the phalanges. The purpose of this study is to report 5 cases with histologic diagnosis of phalanx osteoid osteoma and highlight the most important aspects of its diagnosis and treatment. Materials and Methods: A descriptive, retrospective study was conducted. Evaluation included pain level using the visual analog scale (VAS), active range of motion, and QuickDASH score before surgery and at final follow-up (mean, 35.4 months). Results: The mean time from first consultation to diagnosis was 10.6 months (range, 5-16 months). The mean preoperative QuickDASH score was 22.72 (range, 6.8-40.9). At last follow-up (mean, 35.4 months; range, 17-63), all patients were satisfied with the outcome. The mean VAS score for pain was 0. The mean QuickDASH score was 0. Conclusions: Osteoid osteoma should be considered in the differential diagnosis when patients complain of subacute or chronic digital pain that improves with NSAIDs. Surgical treatment by simple curettage or en bloc resection shows satisfactory results. However, due to its low prevalence, osteoid osteoma is commonly underdiagnosed resulting in diagnosis and treatment delays. Level of Evidence; IV

Objetivo: Evaluar los resultados y las complicaciones de una serie de pacientes con consolidación viciosa de falange. Materiales y Métodos: Se realizó un estudio retrospectivo que incluyó a pacientes con consolidación viciosa de falange tratados mediante osteotomía en el sitio de la deformidad, estabilizados con osteosíntesis rígida. Se registró la movilidad de los dedos. La valoración subjetiva consistió en el puntaje DASH y una escala analógica visual para el dolor en reposo, en actividad y la función. Resultados: Doce pacientes (13 falanges) cumplieron los criterios de inclusión. El tiempo promedio entre la lesión inicial y la osteotomía fue 14 meses y el seguimiento promedio, 34 meses. La movilidad final promedio en flexo-extensión fue 89° metacarpofalángica, 74° interfalángica proximal, 54° interfalángica distal y la distancia pulpejo-palma, 3 mm. El puntaje promedio de la escala analógica visual en reposo fue 0; en actividad, 1 y la función promedio fue de 7 puntos; el puntaje DASH promedio fue 6. No hubo casos de seudoartrosis. Cinco pacientes requirieron el retiro de la placa. Los pacientes con osteotomía articular no presentaron signos de artrosis. Conclusiones: La osteotomía de falange en el sitio de la deformidad es un procedimiento eficaz con un buen resultado objetivo y subjetivo a corto plazo. La utilización de placas y tornillos conlleva una tasa más alta de complicaciones; por lo tanto, los pacientes deben ser advertidos sobre la posibilidad de una segunda intervención quirúrgica.

Objective: To present the results and complications of a series of phalangeal malunion patients. Materials and Methods: A retrospective study was conducted on phalangeal malunion patients treated with an osteotomy at the deformity site and stabilized with rigid internal fixation. Postoperative mobility of the digit was recorded. The subjective assessment used the Disabilities of the Arm, Shoulder and Hand (DASH) score and a Visual Analogue Scale (VAS) to rate their function and pain at rest and during activity. Results: Twelve patients (13 phalanges) met the inclusion criteria. The average time between fracture and osteotomy was 14 months and the mean follow-up was 34 months. Final mobility in flexo-extension was: 89 degrees for metacarpophalangeal joint, 74 degrees proximal interphalangeal joint, 54 degrees distal interphalangeal joint. The average VAS pain score was 0 at rest and 1 during activity, and the average function was 7 points. The average DASH score was 6. There were no cases of nonunion. Five patients required plate removal. No patients with articular osteotomy presented signs of Osteoarthritis. Conclusions: Phalangeal osteotomy at the deformity site is an effective procedure with good objective and subjective short-term outcomes. Patients should be warned about the possibility of a second procedure in cases of plate fixation due to a higher complication rate associated with plate and screw fixations. Level of Evidence: IV

Las fracturas de falanges y metacarpianos son de las más frecuentes. Las posibilidades quirúrgicas son muy variadas, como también los distintos tipos de fracturas. La dificultad de poder comparar distintos tipos de fractura entre sí hace complejo el análisis del mejor tipo de tratamiento quirúrgico. OBJETIVO: Realizar una revisión actualizada de los distintos manejos quirúrgicos para el tratamiento de las fracturas de falanges y metacarpianos en la mano para decidir el mejor tratamiento para cada tipo de fractura. MATERIALES Y MÉTODOS: Se ha realizado una búsqueda no sistemática en PubMed, Scopus y Embase para localizar artículos sobre manejo quirúrgico de fracturas de falanges y metacarpianos, estudiando todos las zonas y tipos de fractura, así como sus posibilidades quirúrgicas. RESULTADOS: De un total de 56 artículos publicados en los últimos 10 años, se seleccionaron 30 artículos, tras aplicar los criterios de selección y exclusión. Lamayoría fueron revisiones bibliográficas; el resto, estudios retrospectivos y prospectivos, series de casos y 2 ensayos clínicos controlados aleatorizados. CONCLUSIONES: Las posibilidades quirúrgicas para cada zona y tipo de fractura en falanges y metacarpianos son tremendamente variables, actualmente no existe evidencia suficiente que permita establecer el mejor tratamiento para cada fractura. Hacen falta ensayos clínicos de alta calidad
Fractures of phalanges and metacarpals are the most frequent. The surgical possibilities are very different, as there are a plenty of types of fractures. It is difficult to compare different types of fractures with each other, what makes the analysis of the best surgical treatment complex. OBJECTIVES: To perform an updated review of the different surgical procedures for the treatment of phalangeal and metacarpal fractures in the hand to elucidate the best treatment for each type of fracture. METHODS: A non-systematic search has been carried out in PubMed, Scopus and Embase to locate articles on the surgical management of phalangeal and metacarpal fractures, studying all areas and types of fractures, as well as their surgical possibilities. RESULTS: From a total of 56 articles published in the last 10 years, 30 articles were selected, after applying the selection and exclusion criteria. Most of the were bibliographic reviews. The rest were retrospective and prospective studies, case series and 2 randomized controlled clinical trials. CONCLUSIONS: The surgical possibilities for each area and type of fracture in phalanges and metacarpals are very variable, but there is currently insufficient evidence to establish the best treatment for each fracture. High quality clinical trials are needed

Antecedentes y Objetivo. Entre las opciones para cobertura de defectos de piel en mano y especialmente para reconstrucción del pulgar, el colgajo de primera arteria metacarpiana dorsal (PAMD) que utiliza la piel del dorso de la falange proximal del índice es una técnica utilizada desde hace años y que brinda buenos resultados. Nuestro objetivo es actualizar este colgajo mediante una revisión crítica de la literatura al respecto ilustrada con disección en cadáver y su aplicación en varios casos clínicos de nuestra experiencia. Material y método. Revisamos los antecedentes históricos y la anatomía del colgajo y hacemos una descripción detallada de la técnica quirúrgica mediante disección en cadáver, aportando dibujos y fotografías, complementado con la descripción detallada de 4 casos clínicos exitosos. Resultados. Encontramos 21 artículos relevantes sobre el colgajo de PAMD complementados con 2 capítulos de libros de mano. En cuanto a la revisión anatómica en cadáver comprobamos que este colgajo tiene un eje vascular similar al descrito en la literatura y en relación al componente clínico, demostramos que es un colgajo reproducible y seguro. Conclusiones. Teniendo en cuenta las indicaciones precisas y un conocimiento claro de la técnica, el colgajo de PAMD es una alternativa versátil y segura para el tratamiento de defectos cutáneos en mano
Background and Objective. Among coverage options for skin defects on the hand and especially for reconstruction of the thumb, the flap of the first metacarpal dorsal artery that uses the skin of the back of the proximal phalanx of the index, is a well known technique providing good results. Our aim is to carry out an actualization of this flap with a critical review of the literature, illustrated with cadaver dissection, and its application in some clinical cases of our own experience. Methods. We conduct a review of the historical antecedents, the anatomy and a detailed description of the surgical technique by means of dissections in cadaver complemented with drawings and photos and the presentation of 4 successful clinical cases. Results. We found 21 relevant articles complemented with 2 chapters of hand books. Based on these, a detailed documentation of the history, anatomy and surgical technique of the first metacarpal dorsal artery flap was made. On the part of the anatomical revision in corpses it was found that this flap has a vascular axis similar to that described in the literature, and on the part of the clinical application, we demostrate that is a secure and reproducible flap. Conclusions. Taking into account the precise indications and a clear knowledge of the technique, the first metacarpal dorsal artery flap is a versatile and safe alternative for the management of skin defects in the hand

Introducción: Se realizo un estudio de cohorte prospectivo para evaluar los resultados funcionales de pacientes laborales con fracturas de falange tratadas mediante placas y establecer factores de mal pronostico. Materiales y Métodos: Desde mayo de 2012 hasta mayo de 2014, 55 pacientes laborales con fracturas de falange fueron operados consecutivamente, mediante reduccion y osteosintesis con placa y tornillos. Cuarenta y dos (39 hombres, edad promedio 30.76 anos) fueron evaluados, con 68 falanges operadas (primera falange 15, segunda falange 53). El 28% de las fracturas fueron expuestas; el 38,24%, conminutas y el 11,76% tenia compromiso articular. El seguimiento promedio fue de 3.38 meses. Resultados: Se logro la consolidacion osea de todas las fracturas a los 1.8 meses. La movilidad para el pulgar (Gingrass) fue buena en dos casos y regular en uno. En los restantes dedos (Belsky), fue excelente (35%), buena (55%) y mala (9%). El puntaje DASH promedio fue de 18,53. Se observaron peores resultados en las fracturas de la primera falange respecto de la segunda falange y en pacientes con mas edad que en los mas jovenes, ambos con significancia estadistica. No hubo relacion entre el resultado y las demas variables estudiadas. Cuatro pacientes tuvieron complicaciones (9,5%). Conclusiones: Al comparar nuestra serie con otras publicadas, hubo menos complicaciones y los resultados fueron similares, pero a diferencia de otros autores, no acostumbramos a retirar el material ni a realizar tenolisis ni artrolisis. Se logro la consolidacion osea en todos los casos y los resultados fueron satisfactorios en el 90% de los pacientes. Nivel de Evidencia: IV
Introduction: A prospective cohort study was carried out to evaluate functional results in workers with phalangeal fractures treated with plates and to establish poor prognostic factors. Methods: From May 2012 to May 2014, 55 workers with phalangeal fractures were operated on consecutively by reduction and fixation with plate and screws. Forty-two patients (39 men; average age 30.76 years) were evaluated, with 68 operated phalanges (first phalanx 15, second phalanx 53). Twenty-eight percent of fractures were open, 38.24% comminuted and 11.76% had joint involvement. Average follow-up: 3.38 months. Results: Bone union was achieved in all fractures in 1.8 months. Gingrass score for the thumb was good in two cases and regular in one. In the remaining fingers, Belsky score was excellent (35%), good (55%), and poor (9%). Average DASH score was 18.53. Worse results were observed in the first phalanx fractures with respect to the second and in older patients than in the younger, both with statistical significance. No relationship was observed among the outcome and other variables studied. Four patients had complications (9.5%). Conclusions: When comparing our findings with other studies, the rate of complications was small, and similar results were obtained, but unlike other authors, we are not used to removing hardware with tenolysis or arthrolysis. Bone union was achieved in all cases and results were satisfactory in 90% of patients. Level of Evidence: IV

Introducción y Objetivo. El tratamiento de la deformidad quirúrgica creada durante el abordaje de los tumores óseos benignos de la mano, en especial del más frecuente que es el encondroma, es particularmente difícil de cara a conseguir una rehabilitación funcional postoperatoria temprana. Describimos una combinación de elementos técnicos como opción reconstructiva apropiada para estos casos en condiciones similares. Material y método. Los puntos básicos de la técnica son: A) Precisión en la resección tumoral de acuerdo a las imágenes diagnósticas de la tumoración sólida y de su interior de sustitución medular, preservando las estructuras funcionales circundantes. B) Manejo adecuado de la inestabilidad residual mediante injerto óseo autólogo y osteosíntesis rígida. C) Facilitar la integración temprana del tejido óseo autólogo de reemplazo utilizando factores de crecimiento de origen plaquetario. Resultados. Presentamos el abordaje similar de 2 casos resueltos mediante la técnica descrita, con rehabilitación funcional temprana. Conclusiones. Nuestra propuesta supone una muy probable opción reconstructiva integral, relativamente sencilla para la resolución satisfactoria de los defectos óseos secundarios a la extirpación quirúrgica de los encondromas de falange, empleando una combinación de elementos técnicos actualmente disponibles (AU)
Background and Objective. Treatment of the bone tissue surgical defect of the phalanx after a major resection of an enchondroma tumor could be particularly difficult in order to get an early postoperative functional recovery. We describe a combination of technical resources as an appropriate reconstructive option to treat these cases under similar conditions. Methods. Our procedure proposal is based on: A) Appropriate tumor resection according to the diagnostic tumor images and of its medullar inner, preserving surrounding functional structures; B) Proper management of the residual instability with autologous monocortical bone graft and rigid internal fixation; C) Addition of platelet derived growth factors as biological inductors to improve bone graft integration. Results. We present the management of 2 clinical cases solved using the described technique, with an early functional rehabilitation. Conclusions. The satisfactory results obtained are of a sufficient practical value to considerer our technique as an integral reconstructive proposal to get a satisfactory solution of phalanx bone defects after surgical treatment of enchondromas, using a combination of technical resources available nowadays (AU)
