Comparative study between intramedullary interlocking nailing and minimally invasive percutaneous plate osteosynthesis for distal tibia extra-articular fractures / 中华创伤杂志(英文版)

PURPOSE@#Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage. There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique and intramedullary interlocking (IMIL) nailing for extra-articular distal tibia fractures. The aim of our study is to compare the functional outcome between the two treatment methods.@*METHODS@#This was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups. The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing. Patients were followed up in outpatient department to assess the functional outcomes, malunion, delayed union, nonunion, superficial and deep infection between the two groups. Statistical analyses were performed using the SPSS software (version 16.0).@*RESULTS@#Average malunion (degrees) in the MIPPO group was 5 (3-7) ± 1.41 vs. 10.22 (8-14) ± 2.04 in the IMIL group (p = 0.001). Similarly postoperative knee pain in the IMIL group was 10% vs. 2% in the MIPPO group (p = 0.001). In terms of superficial infection and nonunion, the results were 8% vs. 4% and 2% vs. 6% for the MIPPO and IMIL group, respectively (p = 0.001).@*CONCLUSION@#Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue, bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing. Considering the results of the study, we have slightly more preference for the MIPPO technique.

Osteosíntesis mínima invasiva percutánea con placa en fractura de tibia distal / Percutaneous Minimally Invasive Plate Osteosynthesis in Distal Tibial Fracture

Introducción: Las fracturas diafisarias de la tibia tienen una alta incidencia por año, incluidas las del tercio distal. Son las más frecuentes de los huesos largos y se observan sobre todo en adultos jóvenes. Se producen, generalmente, por traumatismos de alta energía como accidentes del tránsito y caídas de alturas. Objetivo: Presentar los resultados del tratamiento realizado a un paciente con fractura extrarticular del tercio distal de la tibia, mediante una técnica de osteosíntesis percutánea mínimamente invasiva. Presentación del caso: Paciente de 45 años, masculino, de piel blanca que sufrió accidente del tránsito, y fue atendido en el servicio de Ortopedia y Traumatología del Hospital General Docente Dr. Antonio Luaces Iraola, con trauma en pierna izquierda. Presentó dolor, inflamación e imposibilidad para caminar. A la exploración física se constató dolor, deformidad, crepitación, movilidad anormal, aumento de volumen e impotencia funcional absoluta. Se realizó radiografía, se corroboró diagnóstico y se decidió tratamiento quirúrgico con técnica mínima invasiva percutánea. Se siguieron los principios de la osteosíntesis biológica y se utilizó placa de segunda generación del sistema AO. Conclusiones: El tiempo quirúrgico fue de 45 minutos, la estadía hospitalaria fue de 48 horas. Se comenzó apoyo parcial a las ocho semanas, y total a las 15 semanas. Se logró la consolidación total de la fractura a las 16 semanas de operado, evaluado de excelente a través de la American Orthopaedic Foot and Ankle Society (AOFAS) score(AU)

Introduction: Diaphyseal fractures of the tibia have high incidence per year, including those of the distal third. They are the most common of the long bones and are seen mostly in young adults. They are generally caused by high-energy trauma such as traffic accidents and falls from heights. Objective: To present the results of the treatment on a patient with extra-articular fracture of the distal third of the tibia, using minimally invasive percutaneous osteosynthesis technique. Case report: A white 45-year-old male patient was injured in a traffic accident, and he was treated in the Orthopedics and Traumatology service at Dr. Antonio Luaces Iraola General Teaching Hospital, because of a trauma to his left leg. He had pain, swelling and inability to walk. Physical examination revealed pain, deformity, crepitus, abnormal mobility, increased volume, and absolute functional impotence. X-rays were performed. The diagnosis was confirmed, and surgical treatment was decided with a minimally invasive percutaneous technique. The principles of biological osteosynthesis were followed and a second generation plate of AO system was used. Conclusions: The surgical time was 45 minutes. The hospital stay was 48 hours. Partial support of the leg was started at eight weeks, and full support at 15 weeks. Full fracture healing was achieved 16 weeks after surgery, the procedure was evaluated as excellent according to the American Orthopedic Foot and Ankle Society (AOFAS) score(AU)

Expanding the horizons of clinical applications of proximal humerus locking plates in the lower extremities: A technical note / 中华创伤杂志(英文版)

Pre-contoured anatomical locking plates were designed to address the clinical need of fixing small epiphyseal segments with a larger number of screws. Those plates match the contour and shape of a variety of bones allowing for optimal buttress properties. The aim of this manuscript is to highlight the benefits of applying proximal humerus locking plates in the fixation of lower extremity bones. Although designed for the proximal humerus, the low-profile plate shape and anatomic contour also provides versatile use in certain areas of the lower extremity. This technical narrative highlights the versatile and reliable use of this plate for other anatomical areas than the one to which it has been originally conceived.

Two-Stage Surgical Procedure in Intra-articular Distal Tibiofibular Fractures with Soft Tissue Injury: in Which Stage Should the Fibular Plate be Applied at Initial Surgery?

@#Introduction: The selection of the stage where fibular plate was performed in two-stage surgery of the intra-articular distal tibiofibular fractures with soft tissue injury is still controversial. The aim of the study was to compare the complications, radiological and functional outcomes between the patients who had fibular plate at initial or second phase during surgical management of such fractures. Materials and Methods: In this study, medical records of 47 patients who underwent a two-stage surgical procedure for intra-articular distal tibia fractures accompanying soft tissue injury were retrospectively examined. Delta frame was applied in all cases within 24 hours following admission to the emergency department in accordance with AO principles. Those cases where fibular plate was applied during the initial stage and the second stage were classified as Group 1 and Group 2 in order to compare recorded data between the two groups. Results: According to the results of the study, there were 25 cases in Group 1 and 22 cases in Group 2 in which fibular plate was applied at the first stage and the second stage, respectively. The mean follow-up was found as 27.7±7.0 months in Group 1 and 28.2±6.2 months in Group 2 (p=0.778). No difference was found between the two groups in terms of the age, sex, hospital stay, the time between two surgical procedures, tibiofibular angle and AOFAS scoring (p>0.05).These two groups were also similar in mechanism of injury, Denise-Weber or AO classification, rates of tibiofibular malalignment on post-operative CT, fibular rotation, intra-articular tibial step-off, tibial varus-valgus duration of union, rate of infection, fibular angulation and the presence of the flap/graft/debridement (p>0.05). Conclusion: In conclusion, two-stage surgical procedure in intra-articular distal tibiofibular fractures may be an effective method decreasing soft tissue complications. The timing of the open reduction and internal fixation of the fibula at different stages may not necessarily have an impact on the success of the post-operative tibial reduction, the total duration of surgery, syndesmosis malalignment or soft tissue complications.

Surgical Management of Distal Tibia Fracture: Towards An Outcome-based Treatment Algorithm

@#Introduction: Distal tibia fractures are frequently associated with an extensive soft tissue injury which then leads to a higher risk of complications such as infection, non-union and eventually poor overall outcome. The purpose of this study is to measure the outcome of distal tibia fractures treated with internal fixation, external fixator or Ilizarov external fixator(IEF). We aim to propose an algorithm for management of distal tibia fractures by evaluating the treatment options, outcomes and risk factors present. Material and Methods: This study is a cross-sectional study of all distal tibia fractures treated surgically in Tengku Ampuan Rahimah Hospital, Klang from 1st January 2016 till 30th June 2018. Patient records were reviewed to analyse the outcomes of surgical treatment and risk factors associated with it. Results: Ninety-one patients were included with a mean age of 41.5 years (SD = 16.4). Thirty-nine cases (42.9%) were open fractures. Thirty-eight patients (41.8%) were treated with internal fixation, 27 patients (29.7%) were treated with IEF and 26 patients (28.6%) were treated with an external fixator. Among open fractures cases, no significant finding can be concluded when comparing each surgical option and its outcome, although one option was seen better than the other in a particular outcome. Initial skeletal traction or temporary spanning external fixator in close fractures reduced the risk of mal-alignment (p value=0.001). Internal fixation is seen superior to IEF and external fixator in close fractures in term of articular surface reduction (p value = 0.043) and risk of mal-alignment (p value = 0.007). Conclusion: There is no single method of fixation that is ideal for all pilon fractures and suitable for all patients. This proposed algorithm can help surgeons in deciding treatment strategies in the challenging management of distal tibia fractures to reduce associated complications.

Análise clínica e radiológica de pacientes em pós-operatório de fratura de terço distal da tíbia: haste intramedular x placa / Clinical and radiological analysis of post-operative patients with distal tibia fractures: intramedullary nail versus plate

Objetivo: Avaliar e comparar os resultados clínicos e radiológicos de pacientes com fratura de tíbia distal, sem acometimento articular, tratados com haste intramedular ou placa e parafusos. Métodos: Foram analisados 27 pacientes, sendo 15 tratados com placa e 12 com haste intramedular, após 6 meses completos de pós operatório. Foram aplicados os escores de EVA e de Olerud-Molander, além de análise radiográfica. A análise estatística foi realizada utilizando os testes de qui quadrado e o teste de Mann-Whitney. Resultados: A média de idade foi de 45 anos e o sexo masculino foi prevalente. Foi observada alta prevalência da fratura de fíbula associada (92,6%) sendo 25,9% fixadas. A media angular de desvio foi de 2,60o nos pacientes tratados com placa e 2,42o nos tratados com haste intramedular (p=0,829). A média do escore da EVA e Escore de Olerud-Molander não mostrou diferença estatisticamente significativa entre os dois grupos. Três pacientes apresentaram pseudoartrose, sendo dois deles tratados com haste. Conclusão: Não houve consenso da superioridade de um método em relação ao outro em nossa análise. A fixação da fibula pode ser um fator determinante no alinhamento das fraturas. Cada um dos métodos apresenta vantagens e desvantagens, porém ambos mostraram resultados bons e semelhantes. A escolha do tratamento deve ser atribuida ao perfil do trauma, a condições clinicas do paciente e a experiencia do profissional.

Objective: To evaluate and compare clinical and radiological outcomes of patients with distal tibial fractures, without joint involvement, treated with intramedularry nail or plate and screws. Methods: twenty seven patiens were analyzed, 15 treated with plates and 12 treated with intramedullary nail, after 6 complete months of postoperative period. The Olerud-Molander Ankle Score and the Visual Analogue Scale for Pain, as well as radiographic analysis. Statistical analysis was performed using the chi-squared and Mann-Whitney tests. Results: The mean age was 45 years and males were more prevalent. A high prevalence of associated fíbula fracture was observed (92,6%), with 25,9% being fixed. The mean angular deviation was 2,6 degreees in patients treated with plate and 2,42 degrees in those treated with nails. (p=0,829). The Olerud-Molander Ankle Scores and the EVA did not show statistically siginifcance difference between the two groups. Three patients evolved with nonunion, two of them being treated with intramedullary nail. Conclusions: There was no consensus of the superiority of one method over the other. Fíbula fixation can be a determining factor int the fracture alingnment. Both methods has advantages and disadvantages, but both shows good and similar results. Treatment's choice shoud be attributed to trauma profile, patient's clinical conditions and surgeon's experience.

Treatment of Fracture Distal Tibia by Distal Tibial Locking Plate Verses Interlocking Nail: A Prospective Comparative Study

Introduction: Fractures of distal third of tibia pose greaterchallenge to the treating surgeon, in view of its relative lack ofvascularity, as it is devoid of muscular envelope and is coveredonly by skin and tendons. Its proximity to the ankle joint makesit further complex than any diaphyseal fracture. A variety oftreatment modalities are available including non operative,external fixation, IM nailing and plating. Whereas, closedreduction and casting is known for redisplacement withresultant malunion and joint stiffness because of prolongedimmobilisation, external fixators are of utility only for compoundfractures of mid third and are known for pin track infections.Material and Methods: A Comparative prospective study oftwo procedures, for displaced fractures of distal third tibia inadults was conducted in Govt. Medical College (GMC),Jammu. 30 patients (Group A) were treated by ClosedReduction and fixation with IMIL Nailing and another 30 (GroupB) were treated by closed reduction and fixation using DistalTibial Locking Plate with MIPPO Technique. The patients werefollowed for a minimum of one year wherein the clinicalparameters, radiological progress and final functional resultswere evaluated as per American Orthopaedic Foot and AnkleSociety Score (AOFAS).Results: There was no significant difference in fracture healingtime or ambulation time. Good to Excellent results of 60% werefound in Group A and 73.3% in Group B. There were 13.3% ofpoor results in Group A as compared to 6.7% of Group B.Overall complication rate was higher in Group A. IMIL Nailinghad to be abandoned in 2 cases (6.7%) and switched on toDTLCP, due to per operative finding of medullary canal beingnarrower than 8 mm in one and curved in another. IMIL GroupA, also had 2 cases (6.7%) bent nail, 2 cases (6.7%) brokennail and another 3 cases (10%) of bent/broken locking bolts.No such implant related complications were observed inGroup B.Conclusion: IMIL Nailing is a technically demandingprocedure, requiring a thorough pre- operative work up and askilled experienced surgeon with all sizes of nails, reamers andalternative options available before contemplating it. However,DTLCP by MIPPO technique is easier to learn, is equallybiological, based on sound AO principles of indirect reductionand stabilization by extra periosteal fixed angle construct. Theprocedure has fewer per operative and postoperativecomplications and gives comparable or better results than IMILNailing. The choice of the procedure should be guided by thesite and geometry of fracture and individual experience of thetreating surgeon.

Extra-articular distal tibial fractures, is interlocking nailing an option? A prospective study of 147 cases / 中华创伤杂志(英文版)

PURPOSE@#Distal tibia fractures comprise about 7%-10% of lower extremity trauma. Because of the peculiarity of the soft tissue and subcutaneous location of the bone there are many controversies in the ideal treatment of distal tibia fractures especially extra articular pilon fractures. Plating is fraught with complications of wound dehiscence and infection. There are limited studies which document outcomes in such cases using intramedullary interlocking nail. We intend to study the outcome and complications of extra articular distal tibial fractures treated with interlocking nailing.@*METHODS@#This is a prospective study conducted in a tertiary care orthopaedic hospital in southern India. There are 147 patients of distal tibia extra-articular fractures managed by IM nailing with follow up of more than one year were included in this study. Only cases with fresh injury (less than 1 week), fracture below the isthmus, closed and open Gustilo Anderson type 1 and 2 fractures were included in the study. Patients were reviewed at 3, 6, 12 and 24 weeks after surgery and thereafter at one year and were assessed for clinical and radiological signs of healing, any complications, time to union and functional outcome.@*RESULTS@#There were 102 males and 45 females (male/female ratio is 2.3:1) with a mean age of 38.96 (range 23-65) years. According to AO classification, there were 78 cases (53.06%) of 43-A1, 39 cases (26.53%) of 43-A2 and 30 cases of 43-A3 constituting 20.40%. The fracture united in all the patients at an average of 18 weeks (range 16-22 weeks), none of the patient in our series had a delayed or non-union. Two patients (1.47%) had the fracture united in mild valgus but it was well within the acceptable limits (<5°). The functional outcome was assessed in all the patients at final follow up using Olerud and Molander score all the patients fared an excellent to good score, there were no cases with poor score.@*CONCLUSION@#Intramedullary nailing is a viable option to treat distal tibial fractures with excellent outcome. Wound complications related to plating can be avoided but meticulous surgical technique is key to avoid malunion.

Pseudoaneurysm of the Anterior Tibial Artery after Reduction with Pointed Bone Reduction Forceps on a Spiral Fracture of the Distal Tibia: A Case Report

This paper reports a pseudoaneurysm of the anterior tibial artery after reduction with pointed bone reduction forceps on a spiral fracture of the distal tibia. Most reported injuries occurred at the proximal part of anterior tibial artery during drilling of the proximal tibia. To the best of the authors' knowledge, injury of the distal part of anterior tibial artery has never been reported. This paper describes a 54-year-old woman with a pseudoaneurysm of the anterior tibial artery clinically detected 11 weeks after the index surgery. This report highlights the need for surgeons to be aware of and careful about this complication during and after surgical intervention.

Manejo expectante de osteocondroma solitario interóseo de la tibia distal: reporte de un caso y revisión de la literatura / Non-surgical management of an interosseous solitary osteochondroma of the distal tibia: a case report and review of the literature

La localización del osteocondroma en la tibia distal es poco frecuente y su crecimiento con compromiso y deformidad del peroné distal es aún más raro, haciéndolo una condición más sintomática que en otras ubicaciones. Factores como la severidad de los síntomas, deformidad progresiva del tobillo, complicaciones sindesmóticas, riesgo de fractura patológica o transformación maligna, junto con nuevas y mejores técnicas quirúrgicas, han llevado a que el manejo expectante de esas lesiones sea excepcional y escasamente reportado. Presentamos el caso de un joven de 17 años con osteocondroma solitario interóseo tibio distal sintomático y compromiso fibular, que fue exitosamente manejado en forma expectante. A los 5 años de seguimiento clínico-radiológico no presenta complicaciones y la lesión se mantiene estable.

Osteochondromas located in the distal tibia are a rare condition, and the involvement of the distal fibula with deformity is even more uncommon. Factors such as the severity of symptoms, progressive deformity of the ankle, syndesmotic complications, the risk of pathological fracture or malignant transformation, together with new and safer surgical techniques, have led to scarce reports of non-surgical management. We present a case report of a 17-year-old male with a symptomatic interosseous solitary osteochondroma in the distal tibia with fibular involvement, which was successfully managed non surgically. After 5 years of clinical and radiological follow-up, he has no complications, and the lesion remains stable.

Outcomes Of Distal Tibial Metaphyseal Fractures (type 43a) By Locked Intramedullary Nailing. Outcomes From A Rural Set Up

Fractures in the distal tibial metaphysis are more complicated to treat than diaphyseal fractures. The treatment of distal metaphyseal tibial fractures remains controversial. This retrospective study was performed in a rural set up to review the outcomes of distal tibial metaphyseal fractures by locked intramedullary nailing and its outcome in rural setup.

Progress in repair and reconstruction of large segmental bone tumor defect in distal tibia / 中国修复重建外科杂志

Objective: To review the methods of repair and reconstruction of the large segmental bone tumor defect in distal tibia. Methods: The related literature of repair and reconstruction of the large segmental bone tumor defect in disatal tibia were reviewed and analyzed from the aspects of the reserved ankle joint and the non-reserved ankle joint. Results: The large segmental bone tumor defect in distak tibia is not rare in clinical. In addition to conventional allograft bone transplantation, vascularized autologous fibular transplantation, vascularized fibular allograft, inactivated tumor regeneration, distraction osteogenesis, and bone transport techniques; membrane-induced osteogenesis, artificial tumor stem prosthesis, three-dimensional printed metal trabecular prosthesis, ankle arthrodesis, artificial tumor ankle joint placement surgery are now gradually applied to the repair and reconstruction of large segmental bone defects in the distal tibia. Moreover, due to its long survival time, the function of reconstruction of the bone tumor defect in the distal tibia has also received increasing attention. Conclusion: Although the ideal methods of repair and reconstruction of the large segmental bone tumor defect in the distal tibia has not yet been developed, great progress has been achieved. Recently, with the appearance of three-dimensional printing and various preoperative simulation techniques, personalized and precise therapy could become ture, but therapies for the large segmental bone tumor defect in the distal tibia still need to be further explored.

OBJECTIVE@#To analyze the operative methods and clinical effects of autologous distal tibial cancellous bone graft with periosteum in treating cartilage injury of talus with Hepple III-IV type.@*METHODS@#From June 2014 to August 2017, 25 patients (25 feet) with Hepple III to IV cartilage injury of talus were treated with autogenous ipsilateral distal tibial cancellous bone graft. Including 14 males and 11 females, aged from 18 to 52 years with an average of (38.4±3.1) years; left foot was in 8 cases and right foot was in 17 cases. According to Hepple classification, type III of 9 cases, type IV of 16 cases. The curative effect was assessed by Amercian orthopedic foot and ankle society (AOFAS) and visual analogue scale (VAS) before operation and 12 months after operation.@*RESULTS@#All 25 patients were followed up for 12 to 28 months with an average of (14.2±2.5) months. AOFAS and VAS scores were improved from preoperative 53.02±10.06, 8.02±1.14 to 88.04±7.45, 1.26±1.74 at 12 months after operation (<0.05). According to AOFAS standard, 16 cases got excellent results, 6 good, 3 poor.@*CONCLUSIONS@#Autologous distal tibial cancellous bone graft with periosteum is an effective method for Hepple III-IV cartilage injury of talus. It can effectively relieve ankle pain and improve ankle joint function.

Introducción: Los traumatismos de alta energía en miembros inferiores se asocian, con frecuencia, a defectos de partes blandas y su reconstrucción puede presentarse como una tarea desafiante. En el extremo distal de la pierna y el pie, los colgajos de perforantes representan la mejor opción de cobertura. El motivo de este trabajo es comunicar el resultado del tratamiento de lesiones de partes blandas de pierna distal, tobillo y talón utilizando exclusivamente el colgajo de perforantes fasciocutáneo sural. Materiales y Métodos: Entre marzo de 2008 y febrero de 2016, en nuestro Hospital, se realizaron 37 colgajos fasciocutáneos surales en 35 pacientes. El criterio de inclusión fue todo paciente con defecto tegumentario en el tercio distal de tibia y talón con exposición ósea, tendinosa o defecto de la almohadilla plantar. La edad promedio fue de 49.6 años y el seguimiento promedio, de 18 meses. Resultados: Se logró la cobertura completa de defecto de tejidos blandos en 29 casos. Se detectaron tres colgajos con necrosis parcial y cinco con necrosis completa; cuatro de estos pacientes tenían antecedentes de enfermedad vascular. El tamaño del defecto fue de 9,6 x 6,7 cm (15 x 9). Conclusiones: Aunque esta serie no es extensa, los resultados coinciden con los publicados. Creemos que este colgajo es una alternativa viable para lesiones distales de pierna y pie, con una baja tasa de complicaciones y de morbilidad en el miembro afectado, y con resultados satisfactorios. Nivel de Evidencia: IV

Introduction: High energy injuries in lower limbs are frequently associated with soft tissue defect and soft tissue reconstruction can be a challenge. Perforator flaps are the best option to cover soft tissue defects in the lower leg, ankle and foot. The objective of this paper is to report the results after the use of a distally-based reverse fasciocutaneous sural flap in the reconstruction of soft tissue loss around the distal leg, ankle and foot. Methods: A total of 37 fasciocutaneous pedicled reverse sural flaps were performed in 35 patients between March 2008 and February 2016, in our Hospital. The inclusion criterium was a soft tissue defect of the lower third of the leg, ankle and heel in which bone, tendons and sole are exposed. Average age: 49.6 years and average follow-up: 18 months. Results: Complete soft tissue defect coverage was achieved in 29 cases. Three flaps with partial necrosis and five with complete necrosis were observed; four of these patients had history of vascular disease. Defect size averaged 9.6 x 6.7 cm (15 x 9). Conclusions: Although this series is not extensive, results are consistent with those reported in the literature. We consider that this flap is a valid alternative for lesions involving the distal leg, ankle and foot, with a low rate of complications and morbidity, and satisfactory results. Level of Evidence: IV

The Result of Using an Additional Mini-Locking Plate for Tibial Pilon Fractures

PURPOSE: We evaluated the usefulness of an additional, 2.7 mm mini-locking plate for tibial pilon fractures. MATERIALS AND METHODS: We studied 21 patients (14 males and 7 females), who were treated with a 2.7 mm mini-locking plate via the anterolateral approach for tibial pilon fractures between September 2012 and April 2014. The mean age was 43.85 years, and the mean follow-up period was 16.6 months. The radiologic outcomes were graded by the Burwell and Charnley modified system and clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score and visual analogue scale (VAS) score. RESULTS: The mean union period was 14.3 weeks. At the final follow-up, radiologic results showed 16 excellent results, 4 fair results, and 1 poor result. The average VAS was 3.4 points; the average AOFAS score was 81.8 points. During the follow-up period, there were three cases of posttraumatic osteoarthritis and one case of superficial skin infection. CONCLUSION: Additional anterolateral, 2.7 mm mini-locking plate may be a good treatment method to manage tibial pilon fractures.

Comparison of the Results between Intramedullary Nailing and Plate Fixation for Distal Tibia Fractures / 대한족부족관절학회지

PURPOSE: We analyzed and compared the clinical and radiologic results between minimally invasive plate osteosynthesis and internal fixation using intramedullary (IM) nail in the treatment of distal tibia fractures. MATERIALS AND METHODS: From March 2005 to June 2013, 65 cases of distal tibia fractures treated with either plate fixation or IM nail fixation were analyzed retrospectively by clinical and radiologic evaluations. The clinical results were compared using the American Orthopaedic Foot and Ankle Society (AOFAS) score, Olerud-Molander ankle score (OMAS), and visual analogue scale (VAS) score at the last follow-up. The radiologic results were compared by time to bone union, complications such as nonunion, delayed union, and malunion. RESULTS: The clinical results (according to OMAS, AOFAS score, and VAS score) were 77.47, 84.76, and 1.75, respectively, in the plating group, and 90.21, 91.00, and 1.25, respectively, in the nailing group, and there was no statistically significant difference. Plating group showed earlier union than the nailing group and the nailing group showed higher frequency of non-union and delayed union than plating group. CONCLUSION: In treatment of distal tibia fractures, two methods showed appropriate results. Therefore, thorough investigation of the types of fracture, state of soft tissues, and advantages and disadvantages of the two methods should be conducted in the treatment of distal tibia fractures.

Colgajo fasciocutáneo sural inverso para cobertura de defectos de partes blandas en pierna, tobillo y pie / Reverse fasciocutaneous sural flap for soft-tissue coverage in leg, ankle and foot

Introducción: El objetivo de este trabajo es evaluar los resultados obtenidos con la utilización del colgajo fasciocutáneo sural de base distal para la reconstrucción de defectos de partes blandas alrededor de la tibia distal, el tobillo y el pie. Materiales y Métodos: Se evaluaron, en forma retrospectiva, 20 colgajos pediculados fasciocutáneos surales inversos realizados entre 2007 y 2013. la edad promedio de los pacientes era de 42 años (rango 6-79); 14 hombres y 5 mujeres. las causas de los defectos fueron: postraumáticas (17 casos, un caso bilateral) y secundarias a resecciones oncológicas (2 casos). la muestra incluyó tres pacientes diabéticos, una mujer obesa y ocho pacientes tabaquistas. en 10 casos, las heridas presentaban exposición tendinosa y, en 10 casos, exposición ósea. el diámetro promedio de los defectos fue de 8,9 x 5,75 cm. Resultados: El seguimiento promedio fue de 16 meses. se logró una exitosa cobertura completa del defecto en los 20 casos. el tiempo promedio de internación fue de 3.15 días. tres colgajos presentaron necrosis parcial superficial, en un caso el colgajo sufrió necrosis en su tercio distal y, en un paciente, se decidió amputar la extremidad por persistencia de la osteomielitis. Conclusiones: Pese a que se han descrito múltiples opciones de cobertura en defectos de tejidos blandos alrededor de la tibia distal, el tobillo y el pie, el colgajo sural inverso es, en la actualidad, uno de los procedimientos más frecuentes para cubrir estos defectos. se evaluaron 20 colgajos surales inversos y se logró la cobertura completa de los defectos de tejidos blandos, tanto en defectos postraumáticos como en los resultantes de resecciones oncológicas.

Background: The objective of this paper is to evaluate the results after the use of distally-based reverse fasciocutaneous sural flap in the reconstruction of soft-tissue loss around the distal tibia, ankle and foot. Methods: Twenty fasciocutaneous pedicled reverse sural flaps performed between 2007 and 2013 were retrospectively evaluated. Average age of the patients: 42 years (range 6-79), 14 were male and 5 were female. soft-tissue loss was post-traumatic in 17 cases (one bilateral) and secondary to oncologic resections in two cases. the series included three diabetic patients, one obese woman, and eight smokers. ten cases had exposed tendons and ten had bony exposure. defect size averaged 8.9 x 5.75 cm. Results: Follow-up averaged 16 months. complete soft tissue defect coverage was achieved in all 20 cases. Hospital stay averaged 3.15 days. three flaps had superficial necrosis, one flap suffered necrosis of its distal third, and the lower extremity was amputated in a patient due to persistent osteomyelitis. Conclusions: Although multiple coverage options have been described for soft-tissue coverage around the distal tibia, ankle and foot, the reverse sural flap is one of the most frequently used procedures to cover these defects. We evaluated 20 reverse sural flaps, achieving complete soft-tissue coverage in post-traumatic lesions as well as in those defects resulting from oncologic resections.

A Comparison of the Results between Intramedullary Nailing and Minimally Invasive Plate Osteosynthesis in Distal Tibia Fractures / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to compare the results of treatment of distal tibial fractures between intramedullary (IM) nailing and minimally invasive plate osteosynthesis (MIPO). MATERIALS AND METHODS: Between January 2007 and February 2012, 57 patients (57 cases) were treated for distal tibial fractures. Thirty-two patients (32 cases) were treated with IM nailing (nail group) and the 25 patients (25 feet) were treated with MIPO (plate group). Clinical results were compared using range of motion (ROM) of the ankle joint, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Olerud-Molander score between nail group and plate group. Radiographic results were compared using mean bony union time, coronal and sagittal malunions, and shortening between the groups. RESULTS: Mean ROM of the ankle joint was significantly larger in nail group until 6 months after surgery; however, it was not different between two groups at the last follow-up. AOFAS score and Olerud-Molander score were not different between two groups at the last follow-up. In the nail group, two malunions more than 5 degrees were observed in coronal and sagittal planes, respectively. One case showed non-union in the plate group, however, bone union was obtained after autogeneous bone graft. CONCLUSION: Treatment using IM nailing is more advantageous in terms of postoperative rehabilitation than MIPO in distal tibial fractures.

Minimally Invasive Plate Osteosynthesis for Fractures of Distal Tibia / 고신대학교의과대학학술지

OBJECTIVES: This study analyzed clinical and radiologic results, and complications of minimally invasive plate osteosynthesis(MIPO) for distal tibia fracture. METHODS: 16 patients (17 cases) who were performed MIPO for distal tibia fractures between January 2007 and June 2011, post-operative followed up at least for one year, were selected for this study. The average age was 55.0(26-76) years old and the average period of follow-up was 15.1(6-27) months. Most of the patients were encouraged to perform ankle dorsiflexion and straight leg raising exercise on splints, from the next day of the operation. As radiologic evaluation, we checked period until bone union, degree of angulation. And post-operative complications were also checked. For functional evaluation of the ankles, American Orthopaedic Foot and Ankle Society(AOFAS) score was used. RESULTS: 16 of the 17 cases were achieved primary bone union, and average period of bone union in all the cases was 17.4 (12-42) weeks. Mean varus/valgus angulation after the bone union was 0.8 degrees and mean anteroposterior(AP) angulation was 1.8 degrees. Mean AOFAS score was 85.2(71-95) points; 5 cases of excellent, 10 cases of good, 1 case of fair, showing that 93.8% of the patients represented at least good AOFAS scores. As complications, there were 2 cases of superficial infection, and each 1 case of nonunion and skin irritation. There were no cases of deep infection, metal breakage, nor limb length discrepancy. CONCLUSIONS: MIPO for distal tibia fracture is considered to be an effective operative method, because of its high bone union rate and low complications by minimal disruption of soft tissue and improved bone fixation strength. Also, for earlier return to daily life, ankle joint exercise should be started as soon as possible after the operation.

Analysis of the Result Treated with Locking Compression Plate-Distal Tibia and Zimmer Periarticular Locking Plate in Distal Tibia Fracture

PURPOSE: To evaluate the clinical and radiological results of minimally invasive plate, osteosynthesis, using either a locking compression plate-distal tibia (LCP-DT) or Zimmer periarticular locking plate (ZPLP) for distal tibia fractures. MATERIALS AND METHODS: Fifty one patients (51 cases), who underwent minimally invasive osteosynthesis using locking compression plate for distal tibia fractures between October 2008 and August 2011, were followed for more than six months. Eighteen patients were treated with LCP-DT and 33 patients with ZPLP. Time to bony union and anatomic alignment were evaluated radiologically. Clinically, American Orthopedic Foot & Ankle Society ankle-hindfoot scales (AOFAS score) and range of ankle motion were assessed and compared between two groups. RESULTS: All patients achieved bony union at an average of 18 weeks on LCP-DT group and 16weeks on ZPLP group. The average American Orthopedic Foot & Ankle Society ankle-hindfoot scales was 83.3 points on the LCP-DT group, 84.6 points on the ZPLP group, and range of ankle motion averaged at 45 degrees, 48 degrees, respectively. CONCLUSION: Both types of locking compression plates were effective when performing minimally invasive osteosynthesis for distal tibia fractures.
