The wrist joint is formed by the distal end of the radius and ulna proximally, and eight carpal bones distally. It has many ligaments to maintain stability of the complex bony structures. The incidence of ligament injuries of the wrist has increased due to sports activities. However, diagnosis and management of these injuries are sometimes difficult because of the anatomic complexity and variable injury patterns. Among them, scapholunate ligament injury and triangular fibrocartilage tears are the two most common injuries resulting in chronic disabling wrist pain. Thorough understanding of the wrist anatomy and physical and radiologic examination is mandatory for proper diagnosis and management of these conditions. This article will briefly discuss the wrist joint anatomy and biomechanics, and review the diagnosis and management of the scapholunate ligament injury and triangular fibrocartilage injury.

High tension electrical burns affecting the wrist are likely to produce full thickness necrosis of the skin and to damage deep vital structures beneath the eschar, affecting he local tendons, nerves, vessels, even bones and joints which result in serious dysfunction of the hand. An aggressive approach to the treatment of these severe wounds and adequate wound coverage are essential for the successful result. From October 1997 to February 2000, we had treated 23 electrical wrist injuries in 20 patients with free flaps. Among these, 13 anterolateral thigh flaps, 5 forearm flaps, 2 scapular flaps, 2 parascapular flaps, and 1 medial leg flap were executed. About 2-4 weeks after initial injury, we tried free flaps. Preoperative debridement was not carried out. At the time of surgery, debridement of all nonviable tissue was done, but nerves, tendons, and bones were left in place with minimal or no debridement when they had anatomic continuity, regardless of their appearance of viability. In all cases, successful soft tissue coverage and wound healing were achieved, and we obtained the following conclusions. 1. Flap coverage should be executed before damage of the tendons, nerves, vessels. 2. As long as the free flap survives, the infected tendons, nerves, and denuded bone can be salvaged. 3. For later reconstruction of the wrist, fasciocutaneous flap should be preferred to promise tendon gliding and endure several operative procedures.

BACKGROUND: The purpose of this study was to elucidate the effects of fluid on the acid-base and electrolytes status and renal function after kidney transplantation (KT). METHODS: We retrospectively analyzed 103 patients who underwent KT. Analyses were performed separately according to the donor type (living, 52; deceased, 51). In the living donor KT group, 28 patients received normal saline solution (NS) and 24 patients received Hartmann's solution (HS). In the deceased donor KT group, 27 patients received NS, and 24 received HS. The acid-base and electrolyte status, urine volume, and renal function between patients receiving NS and patients receiving HS were compared in each group. RESULTS: Regardless of donor type, there were no differences in potassium, pH, base excess, PCO2 and HCO3 between HS and NS on immediate postoperative and postoperative day 1. However, changes to neutral acid-base balance in terms of pH, HCO3, and base excess were significantly higher in HS than in NS. In living donor KT, NS increased serum potassium and chloride significantly during fluid therapy. On postoperative day 7, renal function showed no difference between two groups but urine volume was significantly larger in NS than in HS. CONCLUSIONS: HS does not increase the incidence of hyperkalemia after KT. The use of HS resulted in less metabolic acidosis than the use of NS. Renal function was similar but polyuria was more severe in patients who received NS than in those who received HS.

PURPOSE: This study was performed in order to compare unenhanced CT with diffusion-weighted, T2-weight-ed,and fast FLAIR MR imaging in the detection of hyperacute cerebral ischema induced in a dog and to deter-mine whichmodality first detected cerebral ischemia. MATERIALS AND METHODS: Experimental cerebral infarction was induced bythe occlusion of intracerebral arter-ies using embolic materials (polyvinyl-alcohol, 300 -6 00 micro) introducedthrough a microcatheter into the internal carotid artery of five dogs weighing 12 -20 kg. Serial CT and MR imageswere obtained at one hour intervals from one to five hours after occlusion, and were analyzed independently by tworadiologists. We assessed changes in attenuation, as seen on unenhanced CT and the signal intensity of the lesionon each MR image, and measured the contrast-to-noise ratio (CNR) of the lesions. RESULTS: Ischemic lesions weredetected on unenhanced CT 1 -3 hours after occlusion of cerebral arteries. In all dogs, the lesions were detectedearliest on diffusion-weighted images obtained at 1 hour. They were detect-ed on T2-weighted images at 3 -5 hoursand on fast FLAIR images of 2 -5 hours. The CNR of ischemic lesions increased gradually during the 5-hour period.It was highest on diffusion-weighted images, while on unen-hanced CT, T2-weighted, and fast FLAIR images it wassimilar. CONCLUSION: Hyperacute ischemic lesions were detected earliest on diffusion-weighted images, and earlieron unenhanced CT than on fast FLAIR or T2-weighted MR image.

Pain control is very important in managing terminal cancer patients and there are several modalities to alleviate their pain. A high dosage of epidural morphine is effective to control terminal cancer pain. Furthermore, to decrease the amount of morphine, adding an alternative adjuvant like ketamine to the morphine regimen is considered helpful for controlling the pain of a terminal cancer patient. A 45 year old male patient with terminal lung cancer had neck pain that was caused by multiple bone metastases. Continuous epidural block was started with 2 mg/day of morphine and the dosage was gradually increased to 90 mg/day in 86 days. 30 mg/day of ketamine was then added to it. Overall, the morphine and ketamine dosages were increased to 564 mg/day and 140 mg/day, respectively, in 11 months until the patient expired. In this case, the high dosage of epidural morphine, 580 mg/day, was administered to control cancer pain without any severe adverse effects.

PURPOSE: The object of this study is to evaluate the clinical and radiographic outcomes of two different kinds of dorsal plating for dorsally displaced distal radius fractures. METHODS: Forty-three patients with dorsal plate fixation for distal radius fracture were retrospectively reviewed. Twenty-four patients were treated with nonlocking dorsal plate (group I) and nineteen patients with locking dorsal plate (group II). Range of motion and Green and O'Brien score were evaluated as clinical results, and radial inclination, radial length, volar tilt at postoperative and last follow up were evaluated as radiographic results. RESULTS: According to AO classification system, there were 18 type A fractures, 4 type B fractures, 21 type C fractures. In group I, the mean flexion and extension were 65.0degrees and 65.3degrees, respectively; ulnar and radial deviation were 25.5degrees and 20.8degrees; pronation and supination were 80.0degrees and 80.4degrees. In group II, the mean flexion and extension were 64.5degrees and 67.3degrees, respectively; ulnar and radial deviation were 30.6degrees and 20.6degrees; pronation and supination were 81.4degrees and 78.6degrees. The mean Green and O'Brien score was 94.4 in group I and 92.2 in group II, and 41 patients had satisfactory result. There was no statistical significant difference in clinical results between the groups. Results of postoperative and last follow-up radiographic analyses for mean radial inclination were 23.9degrees and 24.1degrees in group I, respectively, and 24.2degrees and 24.9degrees in group II; radial length were 9.9 mm and 9.7 mm in group I, and 10.1 mm and 9.2 mm in group II; mean volar tilt were 12.2degrees and 13.1degrees in group I, and 14.8degrees and 13.7degrees in group II. There were no statistical significant changes within radiographic parameters. No extensor tendon rupture was reported. CONCLUSION: Dorsal plate fixation for dorsally displaced distal radius fracture showed satisfactory clinical and radiographic outcomes with low complication rate, regardless of the type of plate.
