Purpose: The purpose of this study is to evaluate the usefulness of ultrasonographic examination for diagnosis and removal of small sized foreign bodies, which invaded extremity but difficulty to find on physical examination and/or plane radiographs. Materials and Methods: Since March, 2009 to February, 2012, we performed preoperatively ultrasonography and operation in 9 cases of foreign bodies of hand or foot. Mean symptom duration periods was 32 months. The location were fingers in 5, palms in 2, hand dorsum in 1, heel in 1 case. In 2 cases, foreign bodies were seen on plane radiographs. In the remaining 7 cases, foreign bodies could be diagnosed by ultrasonography only. Using high resolution stick probe, we performed evaluation on size, location, character of foreign bodies and compared preoperative ultrasonographic findings to intraoperative ones. Results: The site of foreign bodies in preoperative ultrasonography corresponded well with intraoperative findings. Foreign bodies were glass particles in 5, plant thorns in 4, pencil lead in 1. Mean size was 3.9 mm (2~7 mm). Conclusion: Ultrasonography is usefull evaluation tool for diagnosis and treatment in whom residual foreign bodies were suspected.

Purpose: The evaluation and management of a completely transected tendon of the hand is relatively clear. In most cases, the integrity is assessed by physical examination(eg, broken normal cascade, motion loss) but occasionally, It happens in troubles. because of pain, limited patient cooperation(eg, child, unconscious patient), and other associated injuries(eg, fractures, foreign bodies). Methods: From september 2006 to August 2007, 28 patients were evaluated with real time ultrasonography preoperatively and postoperatively. Twenty eight patients with injured tendon were evaluated using an HDI 5000 Sono CT(Philips Medical Systems, Bothell, WA) machine with a high resolution, 7.5MHz hockey stick linear probe. Dynamic evaluation was performed in real time. Results: Surgery was performed after the ultrasonographic evaluation. Sonographic diagnosis and intraoperative findings were correlated. Ultrasonographic findings show tendon discontinuity, gaps, and fluid collection. Conclusion: We conclude that ultrasonography is helpful in evaluating and managing acute tendon injury. Especially, in cases of completely lacerated tendon, ultrasonography can identify the location of the proximal tendon stump and partial lacerated tendon, ultrasonographic diagnostic tool can decrease misdiagnosis.
