ABSTRACT
PURPOSE: The purpose was to describe comparative analysis of the surgical outcome of percutaneous K-wire fixation of bony mallet fingers reduced with towel clip and 18-gauge needle. METHODS: We analyzed the bony mallet finger patients with more than twelve months follow-up after percutaneous K-wire fixation. The patients were randomly divided into two groups. Eighteen fingers were treated with closed reduction using towel clip and 18 other fingers were treated with closed reduction using 18-gauge needle. RESULTS: Radiographs showed bony union and no subluxation in all cases after K-wire removal. The average extension lag was 2.8degrees/1.9degrees, and range of motion of distal interphalangeal joint was 70.3degrees/75degrees respectively. According to Crawford's criteria, excellent results were obtained in 9/11 fingers, good results in 8/7 fingers, and poor result in 1/0 finger, respectively. CONCLUSION: 18-gauge needle reduction in percutaneous K-wire fixation is considered less invasive and useful method for treatment of bony mallet finger with comparable results with towel clip reduction.

PURPOSE: To evaluate the clinical results of the treatment of the percutaneous Kirschner wire fixation of bony mallet finger using an 18 gauge needle. MATERIALS AND METHODS: From September 2002 to September 2009, we performed closed reduction using an 18 gauge needle and percutaneous fixation with Kirschner wire for 15 cases of bony mallet finger and followed up at least 1 year. The fractures were classified by the Wehbe and Schneider's method. Indications of operative treatment were fractures involving more than 30% of articular surface, fracture fragments displaced more than 3 mm, or subluxation of the distal interphalangeal joint. The results were evaluated by the Crawford criteria. RESULTS: All the fractures united, with an average healing time of 5.3 weeks(4-6 weeks). According to Crawford criteria, 10 cases were excellent, 5 cases were fair at a mean follow-up of 13 months. There were no pin tract infections and migrations of the pin. CONCLUSION: Percutaneous Kirschner wire fixation of mallet finger using an 18 gauge needle is an easy technique which can achieve anatomical reduction and diminish operation-related complications.

Foi realizado estudo prospectivo que teve como objetivo determinar a sensibilidade e a especificidade da biópsia por fragmentos com agulha de 18 gauge, de menor calibre, abordando a validade da ultra-sonografia como guia do procedimento e a menor quantidade de material necessário ao diagnóstico do nódulo sólido da mama. Foram estudados 39 casos em 37 mamas femininas, diagnosticados nos exames de rastreio ou diagnóstico, em acordo com o sistema Bi-Rads. No total, 110 fragmentos de 22 nódulos malignos e 17 benignos. O padrão-ouro foi a peça cirúrgica. Resultados: A sensibilidade, a especificidade e a exatidão foram de, respectivamente, 100%, 94%, 97%. Conclui-se que o nódulo sólido de mama pode ser biopsiado com agulha de menor calibre, obtendose de 1 a 4 fragmentos para o estudo histopatológico, quando a punção for guiada por ultra-sonografia.
If was done a prospective study of ultrasonography-guided core breast biopsy, in which was used the 18 gauge needle as choice, to find the minimum number of specimens to the diagnostic of the tumor. There have been studied 39 cases in 37 patients with breast tumor seen on screening or diagnostic examination according to Bi-Rads. A number of 110 core-biopsies were realized, 22 malignant and 17 benigns. The gold standard was the histopathology on surgery. Results: The sensitivity, especificity and accuracy were, respectively, 100%, 94% and 97%. It was concluded that ultrasound guided core breast biopsy may be done with 18 gauge needle, getting from 1 to 4 specimens to histopathologic study.
