Supraclavicular brachial plexus blocks are not common in pediatric patients due to the risk of pneumothorax. Ultrasonography is an important tool for identifying nerves during regional anesthesia. Directly visualizing the target nerves and monitoring the distribution of the local anesthetic are potentially significant. In addition, ultrasound monitoring(More)
BACKGROUND A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. METHODS One hundred patients receiving upper limb surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this(More)
BACKGROUND Unstable simple elbow dislocation (USED) repair is challenged by the maintenance of joint reduction; hence, primary repair or reconstruction of disrupted ligaments is required to maintain the congruency and allow early motion of the elbow. We evaluated the effectiveness and the outcome of lateral collateral ligament (LCL) complex repair with(More)
BACKGROUND The purpose of this study is to evaluate the efficacy of computed tomography (CT) scans compared with plain radiographs on detecting the involvement of the sigmoid notch. METHODS This study involved 121 cases diagnosed as the intra-articular distal radius fracture and performed post-reduction CT scans. We determined the presence of the sigmoid(More)
BACKGROUND As intramedullary (IM) fixation is one of the fixation methods used in neck fractures of the fifth metacarpal, an early motion of injured finger can be allowed. The purpose of this study is to evaluate whether immediate active motion affects the stability of antegrade IM fixation in surgical treatment of neck fractures of the fifth metacarpal(More)
This study investigates the relationship between total knee arthroplasty (TKA) and bone mineral density (BMD) in the same and opposite hips. The study prospectively evaluated 24 consecutive patients undergoing TKA (31 knees, 47 hips). The mean follow-up was 48 months. The mean age at latest follow-up was 69 years, and all patients had the preoperative(More)
BACKGROUND The purpose of this study was to investigate the frequency and distribution of associated carpal bone fractures (CBFs) in distal radial fractures (DRFs). METHODS Three hundred and thirteen patients who underwent surgical treatment for DRFs between March 2007 and January 2010 were reviewed retrospectively. In this study, 223 patients who had(More)
BACKGROUND Plate fixation is the most commonly used technique for the treatment of shaft fractures of both forearm bones (SFBFBs). However, all fractures are difficult to treat with plate fixation because of soft tissue injuries, fracture patterns, or the patient's condition. The purpose of this study is to compare the functional results of plate fixation(More)
Acute rupture of flexor tendons following distal radius fracture is very rare. We experienced four cases of acute rupture of flexor tendons that were treated surgically. Injured tendons included flexor pollicis longus, flexor carpi radialis, palmaris longus and third flexor digitorum profundus. A severely displaced fracture with a volar spike of the distal(More)
Methods about removal of intramedullary nail in complicated cases were reported in some literatures but there are no reports about nail removal in the ulna. The authors would like to report such a case and the technique. We removed bone of the inlet site and created another bony window using an osteotome to expose the interlocking screw holes. Only a bony(More)
