Tramadol's unique mechanism of action suggests efficacy as a local anesthetic adjunct for peripheral plexus blockade. Our study demonstrates that tramadol, added to mepivacaine for brachial plexus anesthesia, extends the duration and improves the quality of postoperative analgesia in a dose dependent fashion with acceptable side effects.
Pain, weakness, and sensory loss occur frequently in the hypothenar eminence. However, clinical examination is difficult and nonspecific, and the prescribed imaging technique may be inadequate, or images may be misinterpreted. Different imaging modalities have various degrees of usefulness for the diagnosis of painful pathologic conditions of the hypothenar eminence. Radiography, multidetector computed tomography (CT), multidetector CT arthrography, and magnetic resonance (MR) imaging of the wrist are useful for surveying the anatomy of the hypothenar eminence, the Guyon canal, and the ulnar nerve and artery and for determining the cause of pain or other symptoms. A fracture of the pisiform bone or the hook of the hamate bone, osteoarthritis or osteochondromatosis of the pisotriquetral joint, Guyon canal syndrome, hypothenar hammer syndrome, tendinopathy of the flexor carpi ulnaris, an anomalous muscle, a ganglion cyst, or a tumor may be responsible for ulnar neuropathy. Specific radiographic views, such as the semisupinated oblique view and the lateral view with the hand radially deviated and the thumb abducted, often provide a sufficient basis for the diagnosis of acute fracture of the hook of the hamate or the pisiform bone. Multidetector CT angiography is an efficient method for diagnosing hypothenar hammer syndrome, and multidetector CT arthrography is well suited for evaluation of the pisotriquetral joint. MR imaging is the modality of choice for depiction of the ulnar nerve.
Free tissue transfer has become the most important means of limb salvage treatment after severe trauma. This one-step procedure shortens healing and hospitalization time and minimizes the danger of infection. However, very few studies have considered the use of free tissue transfer for the reconstruction of traumatic limb injuries in children. This study reports 22 such cases treated in the authors' unit between 1993 and 2000 (17 boys and 5 girls; mean age, 8.9 years; age range, 18 months-15 years; 16 lower and 6 upper limbs). All flaps were indicated for repair of acute traumatic defects (20-500 cm2). Five different flaps were used: 12 scapular, 4 latissimus dorsi, 4 serratus anterior, 1 groin, and 1 temporalis fascia. All were successful, except for partial necrosis with the free groin flap. Three flaps requiring reexploration for venous insufficiency had a successful outcome. The microsurgical success rate in this pediatric population is very high, and the state and size of the donor site and recipient vessels have caused no problems. No long-term complications have been noted (mean follow-up, 3.8 years).
Data are reported for a series of 20 patients who were treated with the pins and rubbers traction system for fractures of the proximal interphalangeal joints of the long fingers. This technique allows fracture reduction with external dynamic traction and immediate active mobilization. Two patients in the series were lost to follow-up monitoring. For two others, the pins and rubbers traction system needed to be removed early (during the first week) because of intolerance or infection. Sixteen patients who were reexamined after minimal follow-up periods of 1 year demonstrated a mean active range of motion of 85.9 degrees for the injured joint; only one patient experienced intermittent pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
