Compressão da artéria subclávia por pseudoartrose de clavícula: apresentação na quinta década de vida / Late presentation of critical upper limb ischemia caused by pseudarthrosis of the clavicle

A compressão da artéria subclávia no desfiladeiro torácico é um fenômeno amplamente conhecido. Anormalidades ósseas, como a pseudoartrose da clavícula, podem raramente causar compressão arterial a esse nível. A pseudoartrose pode desenvolver-se em decorrência de um trauma, que é a forma mais comum, ou ser congênita. Os autores descrevem o caso de uma paciente de 44 anos com quadro de isquemia crítica de membro superior direito. Apresentava história de fratura não tratada de clavícula direita aos 9 meses de idade que evoluiu com pseudoartrose e compressão extrínseca com oclusão da artéria subclávia. O segmento da clavicula acometido pela pseudoartrose foi ressecado e realizada uma tromboembolectomia tardia das artérias subclávia, braquial e distais, com boa evolução.

Compression of the subclavian artery in the thoracic outlet is a well-known phenomenon. In rare cases, bone abnormalities, such as pseudarthrosis of the clavicle, can cause arterial compression at this level. Pseudarthrosis may develop as a result of trauma, which is the more common form, or it may be congenital. Here, the authors describe the case of a 44-year-old patient with critical ischemia of the right upper limb. She had a history of untreated right clavicle fracture at 9 months of age which had progressed to pseudarthrosis and extrinsic compression of the subclavian artery causing occlusion. The segment of the clavicle involved was resected and late thromboembolectomy of the subclavian, brachial, distal arteries was performed, with good results.

Propósito: Presentar el resultado exitoso de la técnica de formación de un solo hueso en antebrazo en un paciente con fractura inicial de cúbito con múltiples osteosíntesis e injertos fallidos. Caso: Paciente masculino dedicado a labores del campo que, a los 39 años de edad, sufre fractura de cúbito izquierdo, después de una evolución de 13 años y 5 intervenciones quirúrgicas con diversos tipos de osteosíntesis e injertos fallidos, que finalizaron en seudoartrosis infectada de cúbito izquierdo, decidiendo efectuarle la formación de un solo hueso en antebrazo evolucionando satisfactoriamente en función. Actualmente: supinación de 20º de antebrazo, flexoextensión de codo y muñeca completas, fuerza muscular adecuada, actualmente integrado en su trabajo de campo sin limitaciones funcionales. Conclusión: La técnica de formación de un solo hueso en antebrazo es, en casos adecuadamente seleccionados, una excelente alternativa de cirugía de reconstrucción o de salvamento en extremidad torácica.

Purpose: To present the successful results of the single-bone reconstruction technique in the forearm in a patient who sustained an ulnar fracture and underwent multiple osteosyntheses and failed grafts. Case: Male patient, agricultural worker, who at age 39 sustained a left ulnar fracture. After 13 years and 5 surgeries involving different types of osteosyntheses and failed grafts, which resulted in infection of the left ulnar pseudoarthrosis, we decided to do a single-bone reconstruction of the forearm. He did well and achieved good function. His current status is: 20º of forearm supination, full elbow and wrist flexion and extension, appropriate muscle strength, and he returned to his job without functional limitations. Conclusion: The single-bone forearm reconstruction technique is, in properly selected cases, an excellent surgical alternative when reconstruction or salvage of the thoracic limb is required.

Pie en espejo / Mirror foot

Paciente masculino de 79 años de edad, el cual presenta en el miembro inferior izquierdo a nivel del pie una malformación congénita que corresponde a un pie en espejo, representado por 9 artejos, articulados en 8 metatarsianos, pie zambo, seudoartrosis alta de la tibia y luxación congénita alta del peroné. Es inusual encontrar esta deformidad en el momento actual.

Here is a 79 years-old patient who had in his left foot a congenital malformation called mirror foot, which is represented by 9 knuckles articulated in 8 metatarsals, knock-kneed foot, upper pseudoarthrosis of the shinbone and upper congenital luxation of the fibula. The presentation of this type of deformity is unusual today.

One-Bone Forearm Procedure for Acquired Pseudoarthrosis of the Ulna Combined with Radial Head Dislocation in a Child: A Case with 20 Years Follow-Up

This report describes a 6 year-old boy who was treated with one-bone forearm procedure for acquired pseudoarthrosis of the ulna combined with radial head dislocation after radical ulna debridement for osteomyelitis. At more than 20 years of follow-up, the patient had a nearly full range of elbow movements with a few additional surgical procedures. Pronation and supination was restricted by 45degrees, but the patient had near-normal elbow and hand functions without the restriction of any daily living activity. This case shows that one-bone forearm formation is a reasonable option for forearm stability in longstanding pseudoarthrosis of the ulna with radial head dislocation in a child.

Su tratamiento a sufrido modificaciones considerables. El objetivo de este trabajo es describir la experiencia de nuestro centro en el manejo de las fracturas supracondileas de fémur. Se revisaron 76 historias con diagnostico de fractura supracondilea de fémur en el Hospital Central del IVSS “Dr. Miguel Pérez Carreño”, en el periodo comprendido de 2004 a 2008; de los cuales 87% son masculinos y 13% femenino, en una edad comprendida entre 10 a 76 años con una promedio de 35 años, el mecanismo de lesión mas frecuente fue heridas por arma de fuego con 37 casos (49%), las fracturas abiertas correspondieron a las tipo III A (69%). En 36 casos se observó un trazo de fractura metafisiario a causa de heridas por arma de fuego, con 47 días de hospitalización en promedio. El 58% de los pacientes recibió tratamiento quirúrgico, entre ellos DCS (48%), clavos endomedulares bloqueados (14%), placas anatómicas dístales de fémur (11%) y tutores en 4 casos, los clavos bloqueados retrógrados se colocaron a 3 pacientes. El 42% recibieron tratamiento conservador con yeso inguinopédico. Como complicaciones se reportaron pseudoartrosis en el 7%; rigidez articular 9% asociado con tornillos canulados, consolidación viciosa en un 25% y acortamiento de 5 cm en promedio de 13% (4 casos) asociado a tratamiento conservador. En cualquier caso el tipo de tratamiento, sea conservador o quirúrgico, requiere una previa valoración cuidadosa de la anatomía de la fractura y de la situación global del paciente.

Fractures of the distal femur are a group of injuries are difficult to manage, the results are not uniformly good and which treatment and recovery requires a considerable effort by the orthopedist and the patient. His treatment has undergone significant changes. The aim of this study is to describe our experience in the management of supracondylar fractures of the femur. 76 stories were revised diagnosis of supracondylar fracture of femur in the Central Hospital “Dr. Miguel Perez Carreño” IVSS in the period from 2004 to 2008, of whom 87% are male and 13% female, at an age between 10 to 76 years with an average of 35 years, the most frequent mechanism of injury was gunshot wounds in 37 cases (49%), open fractures corresponded to type III (69%). In 36 cases showed a metaphyseal fracture line due to gunshot wounds, with 47 days of hospitalization on average. 58% of the patients received surgical treatment, including DCS (48%), locked intramedullary nails (14%), distal femur anatomical plates (11%) and mentors in 4 cases, blocked retrograde nails were placed in 3 patients . 42% received conservative treatment with plaster inguinopédico. Complications included nonunion reported in 7% 9% joint stiffness associated with cannulated screws, malunion in 25% and shortening of 5 cm on average 13% (4 cases) associated with conservative treatment. In any case the type of treatment, whether conservative or surgical, requires prior careful assessment of the anatomy of the fracture and the overall situation of the patient.

Modelo experimental em ratos para o desenvolvimento de pseudoartrose / Experimental model in rats for the development of pseudoarthrosis

OBJETIVO: Descreve-se a técnica de um novo um modelo de pseudoartrose em Rattus norvegicus albinus livre de espécies patogênicas (SPF). MÉTODOS: Os animais foram aleatoriamente distribuídos em dois Grupos: Grupo 1 - Controle (n =6), Grupo 2 - Experimental (n =6). No grupo Controle realizou-se um acesso ao fêmur, seguido da síntese por planos do músculo e da pele. O grupo Experimental foi submetido à osteotomia do fêmur aduzida da confecção de um retalho pediculado de fáscia lata para interposição entre os segmentos resultantes da fratura induzida cirurgicamente. Prosseguiu-se com o alinhamento e aproximação dos segmentos ósseos, mediante uso de fios de náilon introduzidos em orifícios efetuados na extremidade proximal e distal. RESULTADOS: Estudos radiológico e anatomopatológico evidenciaram a ausência de consolidação óssea com persistência de tecido fibro-osteóide decorridos 120 dias de evolução pós-operatória. CONCLUSÃO: O modelo experimental é adequado para a formação de pseudoartrose em ratos.

OBJECTIVE: We sought to describe a new model of pseudoarthrosis in rats free of pathogenic species (Rattus norvegicus albinus - SPF). METHODS: The animals were randomly distributed into two groups were used: Group 1 - Control (n =6); Group 2 - Experimental (n =6). In the Control group an access to the femur followed by the synthesis of the muscular and skin layers was done. The Experimental group was submitted to osteotomy of the femur and a pedicle flap of the fascia lata was interposed between the segments resulting from the surgically induced fracture. The procedure was carried on with both alignment and approximation of the fractured bone through the use of mononylon thread introduced into holes created in the proximal and distal. RESULTS: Radiological and anatomopathological studies showed the absence of bone consolidation with persistence of fibro-osteoid tissue up to 120 days of follow-up. CONCLUSION: The experimental model is suitable for the development of a pseudoarthrosis in rats.
