OBJECTIVE@#To explore biomechanical characteristics of minimally invasive different screw fixations in treating Sanders typeⅡcalcaneal fractures.@*METHODS@#Dicom data of calcaneus by CT scan were input into Mimics 21.0 software and Ansys15.0 software to construct three-dimensional finite element digital model of calcaneus;this model was input into UG NX 10.0 software, and calcaneus was cut according to Sanders classification to establish Sanders typeⅡ calcaneus model with posterior articular surface collapse;then simulated minimally invasive screw internal fixation after calcaneal fracture:a screw from posterior articular surface was used to outside-in fix sustentaculum tali, other 4 screws were used to fix calcaneus by different methods through calcaneal tuberosity, and 4 different calcaneal models were obtained. Under the same conditions, 4 types of internal fixation models were loaded respectively, and nonlinear finite element analysis was performed to calculate the stress distribution of different internal fixation models.@*RESULTS@#Under the same condition of loading, the model 3 had smaller displacement value, maximum calcaneus displacement value and maximum equivalent stress value of the screw than other three internal fixation models, and the stress was more dispersed.@*CONCLUSION@#In minimally invasive screw internal fixation of calcaneus fracture, after 1 sustentaculum tali screw fixation, 2 screws crossed fix posterior articular surface from calcaneal tuberosity, 2 screws fix parallelly calcaneocuboid joint from calcaneal tuberosity are more suitable for biomechanical requirements, and could provide basic theory for clinical treatment.

OBJECTIVE@#To compare the clinical efficacy of staged surgery on Sanders Ⅳ calcaneal fractures with soft tissue Ⅲ swelling.@*METHODS@#The clinical data of 76 patients with Sanders type Ⅳ closed calcaneal fracture with soft tissue three-degree swelling treated from June 2017 to May 2020 was retrospectively analyzed, including 54 males and 22 females, aged from 25 to 50 (38.16±10.24) years. The patients were divided into observation group and control group according to different treatment methods. Twenty-four patients in the observation group were treated by staged surgery stageⅠclosed prying traction reduction and Kirschner wire fixation, stageⅡopen reduction and internal fixation with titanium plate, including 17 males and 7 females, aged from 25 to 50 (36.12±9.56) years. There were 52 patients in the control group, including 37 males and 15 females, aged from 25 to 50 (38.32±10.67) years, these patients were treated with open reduction and internal fixation with titanium plate after the dermatoglyphic signs appeared. The swelling subsidence time, the length of hospitalization days, and the incidence of postoperative incision complications were compared between two groups. The Bhler angle, Gissane angle, and calcaneal varus angle were measured by X-ray before and 6 months after operation. American Orthopedic Foot and Ankle Society (AOFAS) about the ankle hindfoot score was used to evaluate the clinical efficacy.@*RESULTS@#All 76 patients were followed up for 8 to 12 (9.52±2.01) months. The swelling subsidence time and hospitalization days in observation group were (12.12± 3.24) d and (24.53±6.44) d, respectively, which in control group were (15.16±4.16) d and (29.46±9.61) d, with statistical difference between two groups (@*CONCLUSION@#Compared with open reduction and internal fixation with titanium plate after the appearance of dermatoglyphic signs, staged surgery for Sanders type Ⅳ calcaneal fractures with soft tissue three-swelling does not increase the risk of soft tissue complications, and can significantly shorten the patient's swelling subsidence time and hospitalization days, improve the quality of fracture reduction and short term function, and relieve pain.

OBJECTIVE@#To measure anatomical data of calcaneofibular ligament (CFL), relevant data of CFL attachment to provide an anatomical basis for CFL reconstruction.@*METHODS@#Twenty-seven adult ankle specimens were selected, including 11 males and 16 females, aged from 22 to 71 years old with an average of (41.6±17.2) years old;9 cases on the left side and 18 cases on the right side. The specimens reserved at least 20 cm above ankle joint and a complete foot, and exclude deformities, fractures, incomplete development and degenerative lesions. CFL was performed detailed anatomical observation, morphological parameters of CFL was measured, and coordinates of fibula side and calcaneal side of CFL in the coordinate axis were measured. The distance between fibula insertion of CFL and fibula tip, distance between calcaneal insertion of CFL and lateral calcaneal nodule, and Angle between CFL and long axis of fibula were also measured.@*RESULTS@#In these 27 specimens, CFL cases were all single bundles and the length of CFL was (32.83 ± 8.19) mm. The center point of fibula attachment in CFL was(2.87± 1.21) mm proximal with a coefficient of variation of 42.16% and (2.08±1.34) mm anteriorly with a coefficient of variation of 64.42%. The center point of calcaneal attachment region of CFL was located on coordinate axis on the distal end (15.32±5.33) mm, with a coefficient of variation of 34.79%, and the posterior part (6.38±2.15) mm, with a coefficient of variation of 33.86%. The distance between center point of fibula attachment and fibula tip was (4.81±0.82) mm. The distance between center point of calcaneal attachment area of CFL and lateral calcaneal nodules was(17.25±3.12) mm. Angle between CFL and fibula axis is (43 ±18)° .@*CONCLUSION@#According to anatomical studies, we could locate the fibula and calcaneal attachment of CFL by anatomical markers around ankle joint. However, the location of CFL attachment has a large variation, and the anatomical characteristics need to be considered in anatomical reconstruction.

OBJECTIVE@#To evaluate clinical effect of poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture.@*METHODS@#From October 2014 to December 2017, 28 patients with Sanders Ⅱ calcaneal fracture were treated with poking reduction cannulated screw guided by Pingle orthopedic muscle-bone interoperability balance theory, including 20 males and 8 females, aged from 24 to 55 years old with an average of (37.2±3.9) years old. Calcaneal width, Bhler angle, and Gissane angle were measured before and after operation, and Maryland Score before and 6 months after operation were compared.@*RESULTS@#All patients were followed up from 12 to 16 months with an average of (13.7±1.3) months. All fractures healed normally, and healing time ranged from 9 to 12 weeks with an average of (10.2±1.3) weeks. No postoperative wound infection, cortical necrosis, or osteomyelitis occurred. The width of the calcaneus decreased from (34.15±2.58) mm before surgery to (30.49±2.37) mm after surgery, Bhler angle increased from (14.16±3.27)° before operation to (31.95±3.07)°after operation, Gissane angle decreased from (128.45±9.04)° before operation to (120.83±8.15)° after operation. Maryland Score was 15.68±4.73 before operation, and was improved to 88.32±2.65 at 6 months after operation;19 patients got excellent result, 6 good, 2 fair and 1 poor.@*CONCLUSION@#Poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture has certain clinical effects, high acceptation of patient, and without special demand for soft tissue around fracture. But it should avoid choosing severe comminuted Sanders Ⅲand Ⅳcalcaneal fracture.

ABSTRACT Objective To compare screw fixation strength for subtalar arthrodesis. Methods Eight matched pairs of cadaver feet underwent subtalar joint arthrodesis with two 7.3mm cannulated screws. Randomization was used to assign screw orientation, such that one foot in each pair was assigned dorsal to plantar screw orientation (DP Group), and the other foot, plantar to dorsal orientation (PD Group). Standard surgical technique with fluoroscopy was used for each approach. Following fixation, each specimen was loaded to failure with a Bionix ® 858 MTS device, applying a downward axial force at a distance to create torque. Torque to failure was compared between DP and PD Groups using Student's t test, with p=0.05 used to determine statistical significance. Results Statistical analysis demonstrated that the mean torque to failure slightly favored the DP Group (37.3Nm) to the PD Group (32.2Nm). However, the difference between the two groups was not statistically significant (p=0.55). Conclusion In subtalar arthrodesis, there is no significant difference in construct strength between dorsal-to-plantar and plantar-to-dorsal screw orientation. The approach chosen by the surgeon should be based on factors other than the biomechanical strength of the screw orientation.

RESUMO Objetivo Comparar a força de fixação dos parafusos para artrodese subtalar. Métodos Oito pares de pés de cadáveres frescos foram submetidos à artrodese da articulação subtalar com dois parafusos canulados de 7,3mm. A randomização foi usada para atribuir a orientação do parafuso, de modo que um pé em cada par foi designado com orientação de dorsal para plantar (Grupo DP), e o outro pé com orientação de plantar para dorsal (Grupo PD). Técnica cirúrgica padrão com radioscopia foi usada para os procedimentos. Após a fixação, cada amostra foi testada até a falha com um dispositivo Bionix®858 MTS, aplicando força axial descendente a uma distância para criar torque. O torque de falha foi comparado entre os Grupos DP e PD, usando o teste t de Student, com p=0,05 usado para determinar significância estatística. Resultados A análise estatística demonstrou que a média do torque até a falha favoreceu ligeiramente o Grupo DP (37,3Nm) em relação ao PD (32,2Nm). No entanto, a diferença entre os dois grupos não foi estatisticamente significativa (p=0,55). Conclusão Na artrodese subtalar, não há diferença significativa na força de compressão entre as orientações dos parafusos dorsal-plantar e plantar-dorsal. A abordagem escolhida pelo cirurgião deve ser baseada em outros fatores, sem preocupação com a força biomecânica da orientação dos parafusos.

RESUMO O pé plano flexível é condição frequente na criança pequena e apresenta forte tendência para correção espontânea, ou tornar-se moderado ou leve no adulto, o que não causará problemas futuros. Entretanto, em uma pequena proporção de casos a deformidade é mais grave, não melhora, o que pode levar ao comprometimento do desempenho mecânico, deformidade e, eventualmente, dor. Nestes casos o tratamento cirúrgico deve ser considerado. O objetivo desta revisão sistemática foi avaliar os resultados da literatura no tratamento do pé plano flexível sintomático da criança ou adolescente por um procedimento bastante frequente que é a osteotomia de alongamento da coluna lateral do calcâneo. Foi realizada busca sistemática eletrônica nas bases de dados PubMed, Web of Science, Cochrane, CINAHL, SciELO, SCOPUS e LILACS por artigos publicados entre março de 1975 e setembro de 2016. Após aplicação dos critérios de elegibilidade, os artigos selecionados foram avaliados quanto aos resultados clínicos, radiográficos e complicações. Dos 341 artigos encontrados nas bases de dados, apenas oito estudos foram selecionados, segundo os critérios de inclusão e exclusão, com um total de 105 pacientes e 167 pés tratados. Somente três autores realizaram estudo prospectivo, mas sem caso controle ou aleatorização. A maioria das publicações no período avaliado é composta por estudos descritivos ou série de casos (nível de evidência III ou IV), com grandes variações metodológicas, mas com alto índice de satisfação dos pacientes e cirurgiões, em relação aos resultados. Entretanto, são necessárias pesquisas com desenho prospectivo, aleatorizado, grupo controle adequado e critérios de avaliação validados.

ABSTRACT Flexible flatfoot is a common condition in small children, which shows a strong tendency to spontaneously correct with their growth or to become moderate or mild in adults, which will not cause future problems. However, in a small number of cases, this condition is more severe, does not improve spontaneously, which may cause mechanical impairment, deformity, and, eventually, pain. In such cases, surgical treatment should be considered. The aim of this systematic review was to evaluate the literature results on the treatment of the symptomatic flexible flatfoot in children or adolescents through a very frequent procedure: calcaneal lateral column lengthening osteotomy, A systematic electronic search in PubMed, Web of Science, Cochrane, CINAHL, SciELO, SCOPUS and LILACS databases was performed. We searched articles published between March 1975 and September 2016. After applying the eligibility criteria, the selected publications were evaluated in relation to their clinical and radiographic results and complications. We found 341 articles in the mentioned databases, but selected only eight studies, according to the inclusion and exclusion criteria. These studies included a total of 105 patients and 167 treated feet. Only three authors performed prospective studies, but without case-control or randomization. The majority of publications were descriptive studies or case series (level of evidence III or IV), with great methodological variations, but with a high satisfaction rate on the part of both patients and surgeons in relation to the results. However, more prospective and randomized studies are required, with adequate control groups and validated evaluation criteria.

ABSTRACT OBJECTIVE: To evaluate the clinical results of surgical treatment of intraarticular fractures of the calcaneus, comparing the use of calcaneal plate and flat plate. METHODS: This was a retrospective study assessing the postoperative results of 25 patients between 2013 and 2015. Patients undergoing surgical treatment of intraarticular fractures of the calcaneus without concomitant surgical lesions were included. Patients who did not complete appropriate follow-up after surgery were excluded from the study. RESULTS: The unavailability of calcaneal plates at resource-limited settings, associated with the availability and lower cost of flat plates, may have been a confounding factor in the present study. However, there was no statistical difference between the outcomes of fractures treated with calcaneal plates or flat plates. CONCLUSION: Statistical inference shows that, when calcaneal plates are not available, it is possible to use flat plates with similar clinical outcomes.

RESUMO OBJETIVO: Avaliar os resultados clínicos do tratamento cirúrgico das fraturas intra-articulares do calcâneo (TCFIAC) e comparar o uso de placa própria para calcâneo (PPC) e placa reta (PR) . MÉTODOS: Estudo retrospectivo que avaliou o resultado pós-operatório de 25 pacientes entre 2013 e 2015. Foram incluídos pacientes submetidos ao TCFIAC e que não apresentavam lesões cirúrgicas concomitantes. Pacientes que não foram devidamente acompanhados no pós-operatório foram excluídos da análise. RESULTADOS: A indisponibilidade da PPC em serviços com recursos limitados, associada à disponibilidade e ao menor custo da PR, pode ter sido fator de confusão no presente estudo. Contudo, não houve diferença estatística entre os resultados das fraturas tratadas com PPC ou PR. CONCLUSÃO: A inferência estatística permite concluir que, na ausência da PPC, é possível usar a PR com desfechos clínicos semelhantes.

Introdução: A cobertura do pé e especialmente da região do calcâneo são desafios técnicos para o cirurgião devido ao alto grau de especialização dos tecidos envolvidos e à relativa imobilidade dos tecidos próximos. Métodos: No presente estudo, apresentamos nossa experiência com uso do retalho baseado na artéria plantar medial para cobertura de defeitos teciduais no pé, especialmente na região de apoio plantar no calcâneo. Doze retalhos da artéria plantar medial feitos de 2001 a 2013 no Hospital Regional da Asa Norte, Brasília, DF, foram incluídos. Resultados: Dos 12 pacientes, 10 eram homens e dois eram mulheres. As indicações foram perda traumática do coxim do calcâneo em 10 pacientes e dorso do pé em dois casos. Todos os retalhos foram elevados como retalhos pediculados fasciocutâneos baseados na artéria plantar medial. Todos os retalhos cicatrizaram sem maiores complicações, exceto um caso com perda parcial. A área doadora foi coberta com enxerto de pele parcial e houve um caso de perda parcial do enxerto. Os retalhos apresentaram uma sensibilidade protetora levemente inferior ao lado normal. Conclusão: De acordo com os resultados, o retalho plantar medial é uma boa opção para cobertura do pé, especialmente do calcâneo. A versatilidade do retalho permite a cobertura de defeitos no calcâneo sobre o tendão de Aquiles e apoio plantar, assim como o dorso do pé. A cobertura da região de apoio plantar com pele de textura similar e sensibilidade protetora confere a esse retalho uma grande vantagem sobre outros retalhos para reconstrução dessa região.

Introduction: Reconstructive coverage of foot defects, especially those of the calcaneus region, is a unique technical challenge for the surgeon due to the high degree of specialization of the tissues involved and the relative immobility of the proximal tissues. Methods: In the present study, we present our experience with the use of the flap based on the medial plantar artery to cover tissue defects in the foot, especially in the region of the calcaneal fat pad. Twelve medial plantar artery flaps constructed from 2001 to 2013 at the As a Norte Regional Hospital, Brasília, DF, were included. Results: Of the 12 patients with the medial plantar artery flaps, 10 were men and 2 were women. The indications were traumatic tissue loss of the plantar fat pad in 10 patients and of the dorsum of the foot in two cases. All flaps were elevated as fasciocutaneous pedicle flaps based on the medial plantar artery. All the flaps healed without major complications, except one case that involved partial loss . The donor area was covered with a partial skin graft and there was one case of partial graft loss. The flap displayed a slightly lower protective sensitivity than the normal side. Conclusion: According to the results, the medial plantar flap is a good option for covering traumatic foot defects, especially those affecting the calcaneus. The versatility of the flap allows the coverage of defects of the calcaneus (e.g., the Achilles tendon and plantar fat pad regions), as well as those affecting the dorsum of the foot. The coverage of the plantar fat pad region with skin of similar texture and protective sensitivity confers to the medial plantar flap a large advantage over other flaps for reconstruction of this region.

To evaluate, compare and identify the surgical technique with best results for treating intra-articular calcaneal fractures, taking into account postoperative outcomes, complications and scoring in the Aofas questionnaire. METHODS: This was a retrospective study on 54 patients with fractures of the calcaneus who underwent surgery between 2002 and 2012 by means of the following techniques: (1) open reduction with extended L-shaped lateral incision and fixation with double-H plate of 3.5 mm; (2) open reduction with minimal incision lateral approach and percutaneous fixation with wires and screws; and (3) open reduction with minimal incision lateral approach and fixation with adjustable monoplanar external fixator. RESULTS: Patients treated using a lateral approach, with fixation using a plate had a mean Aofas score of 76 points; those treated through a minimal incision lateral approach with screw and wire fixation had a mean score of 71 points; and those treated through a minimal incision lateral approach with an external fixator had a mean score of 75 points. The three surgical techniques were shown to be effective for treating intra-articular calcaneal fractures, without any evidence that any of the techniques being superior. CONCLUSION: Intra-articular calcaneal fractures are complex and their treatment should be individualized based on patient characteristics, type of fracture and the surgeon's experience with the surgical technique chosen.

Avaliar, comparar e identificar a técnica cirúrgica com melhor resultado para o tratamento de fraturas intra-articulares do calcâneo, levando em consideração evolução pós-operatória, complicações e pontuação no questionário Aofas. MÉTODOS: Estudo retrospectivo de 54 pacientes com fraturas de calcâneo operados entre e 2002 e 2012 com as técnicas 1) redução aberta com incisão lateral alargada em "L" e fixação com placa duplo "H" de 3,5 mm, 2) redução aberta por incisão lateral econômica e fixação percutânea com fios e parafusos e 3) redução aberta por incisão lateral econômica e fixação com fixador externo monoplanar regulável. RESULTADOS: Pacientes tratados pela via de acesso lateral e fixação com placa tiveram média de 76 pontos na escala Aofas, em pacientes tratados pela via de acesso lateral econômica e fixação com fios e parafuso a média foi de 71 e nos pacientes tratados com via de acesso lateral e fixador externo foi de 75 pontos. As três técnicas cirúrgicas demostraram-se efetivas no tratamento da fratura intra-articular do calcâneo, sem evidência de superioridade de uma técnica sobre as demais. CONCLUSÃO: A fratura intra-articular do calcâneo é uma fratura complexa e seu tratamento deve ser individualizado, baseado nas características do paciente, no tipo de fratura e na experiência do cirurgião com a técnica operatória escolhida.

Introdução: Feridas em pés são muito frequentes e requerem abordagem multidisciplinar para a sua prevenção, tratamento e reabilitação. Quando acometem o calcâneo, oferecem dificuldade ainda maior e podem apresentar complicação com a ocorrência de osteomielite. Debridamento de tecido desvitalizado e antibioticoterapia são etapas obrigatórias para o tratamento. Na reconstrução, retalhos locais ou livres são necessários. Porém, nem todos os pacientes, devido a condições sistêmicas ou de vascularização local, são candidatos a esse tipo de reconstrução e acabam sendo submetidos a amputações. Relato de caso: Os autores relatam dois casos nos quais foram utilizadas calcanectomias subtotais para o tratamento de feridas em calcâneo. Em ambos os casos, foram evitadas as amputações.

Introduction: Feet wounds are very common and require multidisciplinary approach for prevention, treatment and rehabilitation. When involving the calcaneus, they offer even greater difficulty and may complicate with osteomyelitis. Debridement of devitalized tissue and antibiotics are important steps for treatment. For the reconstruction, local or free flaps are needed. However, not all patients, due to systemic conditions or local blood supply, are not candidates for this type of reconstruction and some times are submitted to amputations. Cases Report: The authors report two cases in which subtotals calcanectomies were used for the treatment of wounds in the calcaneus. In both cases, amputations were avoided.

La fascitis plantar, una entidad patológica autolimitante, es una causa común de dolor en el talón en pacientes adultos. El tratamiento quirúrgico está indicado cuando el paciente recibe tratamiento conservador bien vigilado sin obtener mejoría de síntomas entre 4-6 meses. Entre las complicaciones de las técnicas percutáneas se citan: infecciones, persistencia de dolor, lesiones neurológicas, entre otras. Nosotros reportamos un paciente con fractura de calcáneo posterior a fasciotomía plantar percutánea y resección de espolón calcáneo. Se hizo una revisión y discusión de la literatura.

Plantar fasciitis, a self-limiting pathologic entity, is a common cause of heel pain in adult patients. Surgical treatment is indicated when the patient does not improve after receiving conservative treatment for 4-6 months with proper surveillance. The complications of percutaneous techniques include: infection, persistent pain, and neurologic injuries, among others. We report the case of a patient with calcaneus fracture following percutaneous plantar fasciotomy and resection of a calcaneal spur. We conducted a review and discussion of the literature.

Las fracturas del calcáneo representan aproximadamente 2% de todas las fracturas del cuerpo humano y 60% de las fracturas del tarso. Menos del 7% son bilaterales. Las fracturas intra-articulares desplazadas (Sanders Tipo IV) son el resultado de traumatismos de alta energía, usualmente debido a precipitaciones o accidentes automovilísticos. Es una lesión compleja que se asocia con elevados índices de incapacidad cuando no es tratada de forma correcta y oportuna. Se trata de paciente masculino, de 38 años de edad, quien presenta una fractura bilateral de calcáneo Sanders tipo IV, manejada quirúrgicamente, mediante reducción directa, reconstrucción anatómica del calcáneo, osteosíntesis con placa anatómica y artrodesis subtalar. Las fracturas del calcáneo siguen siendo un gran reto para el cirujano ortopedista y traumatólogo debido a la controversia en cuanto a su manejo. El diagnóstico preciso y precoz, basado en estudios imagenológicos, es necesario para una adecuada caracterización de la fractura, planificación preoperatoria y resolución quirúrgica(AU)

Calcaneal fractures represent approximately 2% of all fractures of the body and 60% of fractures of the tarsus. Less than 7% are bilateral. The displaced intra-articular fractures (Sanders type IV) are the result of high energy trauma, usually because of rainfall or auto accidents. It is a complex injury that is associated with high rates of disability when not treated properly and timely. The case of male 38-year-old man presented with bilateral calcaneal fractures Sanders type IV, which were managed surgically by direct reduction of the calcaneus and anatomical reconstruction píate fixation and anatomic subtalar arthrodesis. Calcaneal fractures remain a major challenge for orthopedic surgeons and trauma due to controversy regarding their management. The early and accurate diagnosis based on imaging studies, it is necessary for proper characterization of the fracture, preoperative planning and surgical resolution(AU)

OBJETIVO: Apresentar um desenho de placa em forma de borboleta e sua aplicação no tratamento de fraturas do calcâneo e discutir suas indicações clínicas, vantagens e desvantagens. MÉTODOS: De fevereiro de 2008 a abril de 2010, 22 pacientes com 26 fraturas intra-articulares do calcâneo foram tratados com redução a céu aberto e fixação interna com placa em forma de borboleta. Dezesseis pacientes eram homens e 6 eram mulheres, com média de idade de 36,8 anos. Onze eram pés esquerdos e 15, direitos. De acordo com a classificação de Sanders, 12 eram fraturas de calcâneo Tipo II (inclusive 3 Tipo IIa, 7 Tipo IIb e 2 Tipo IIc) e 14 eram Tipo III (inclusive cinco do Tipo IIIab, 7 Tipo IIIac e duas do Tipo IIIbc). RESULTADOS: Dezessete pacientes (21 pés) foram submetidos a acompanhamento por em média 19,2 meses. Os desfechos funcionais foram avaliados com o sistema Maryland Foot Score. Entre os nove pés com fraturas Tipo II, sete receberam escore excelente e dois, bom. Entre as 12 fraturas Tipo III, seis tiveram escore excelente, cinco, bom e uma, razoável. CONCLUSÃO: A placa em forma de borboleta é aplicável ao tratamento de fraturas do calcâneo do Tipo II e Tipo III de Sanders, com a vantagem de garantir fixação confiável, facilitar a cirurgia, produzir menos complicações pós-operatórias e produzir melhores desfechos clínicos gerais.

OBJECTIVE: To introduce the design of butterfly-shaped plate and its application in treatment for calcaneal fractures, and to discuss its clinical indications, advantages and disadvantages. METHODS: From February 2008 to April 2010, 22 patients with 26 intra-articular calcaneal fractures were treated by open reduction and internal fixation with butterfly-shape plate. Sixteen patients were male and 6 patients were female, with a mean age of 36.8 years. Eleven were left feet and 15, right. According to Sanders classification, 12 were Type II (including 3 Type IIa, 7 Type IIb and 2 Type IIc) and 14 were Type III (including 5 Type IIIab, 7 Type IIIac and 2 Type IIIbc). RESULTS: Seventeen patients (21 feet) were followed-up for an average of 19.2 months. The functional outcomes were assessed using the Maryland Foot Score system. Among the 9 feet with Type II fractures, 7 feet were scored excellent, 2 were good. Among the 12 Type III fractures, 6 were scored excellent, 5 were good, and one was fair. CONCLUSION: The butterfly-shaped plate is applicable to treatment for Sanders Type II and Type III calcaneal fractures, with advantages of ensuring reliable fixation, easier operation, fewer post-operative complications, and better clinical outcomes.

Benign tumors of the calcaneum are rare. Cystic lesions such as simple bone cysts and aneurysmal bone cysts are commonly seen. Aims and Objectives: To evaluate tumors of the calcaneum, which were seen over a 12-year period. Materials and Methods: We analyzed noninfectious, noninflammatory, benign lesions of the calcaneum seen in the Orthopedic Out Patient Department from 1991 to 2003. Twelve such tumors were encountered. There were 11 males and one female and their ages varied from 18 to 53 years with a median of 31. Data was collected from the histopathology reports, radiographs, and inpatient and outpatient records. One of the coauthors reviewed the histopathologic findings of all the tumors. Results: Twelve benign lesions were seen in 12 patients. In our series, cysts predominated, with three aneurysmal bone cysts and five simple bone cysts. The other benign tumors were: one fibrous dysplasia, one vascular hamartoma, one osteoblastoma, and one chondromyxoid fibroma. The bone cysts were treated by curettage, with or without bone grafting, except for one large aneurysmal bone cyst, which was treated by excision of the calcaneum. The postoperative function in this patient was good, with modified footwear. Conclusion: The calcaneum is an uncommon site for most bone tumors, and in our series, bone cysts were the most common benign lesions. Curettage and bone grafting or the use of bone substitutes can be effectively used in the treatment of symptomatic bone cysts of the calcaneum.

La tenosinovitis estenosante de los peroneos que resulta de la hipertrofia del tubérculo peroneo ha sido bien descrita en la literatura, pero la descripción de casos en nuestro medio es escasa. El tratamiento quirúrgico adecuado trata el tubérculo peroneo hipertrofiado, la polea peronea y cualquier patología intrínseca del tendón. Se reportan dos casos de pacientes con dolor crónico y aparición de masa en la región inframaleolar externa de un tobillo, con poca respuesta al manejo conservador. Los pacientes fueron llevados a cirugía con resolución de sus síntomas. En el primer caso, se encontró una hipertrofia de la polea sin prominencia del tubérculo y, en el segundo caso, una hipertrofia del tubérculo con un quiste retinacular (ganglión) asociado.
