ABSTRACT
@#Compression of the median nerve in pregnancy is thought to be due to fluid retention within the carpal tunnel space. We aim to discover the cause of carpal tunnel syndrome (CTS) in pregnancy using high resonance ultrasonography. Methods: This is a cross-sectional study where obstetric patients were screened for CTS and subjected to a non invasive ultrasonic imaging. Results: A total of 63 patients were seen with 25 diagnosed to have CTS (39.7%) and 38 patients had none (60.3%) based on a screening tool. Age ranged from 20-42 years old with the highest range in the 28-30 year old group (34.9%). In patients with CTS, the cross sectional area of the median nerve inside the tunnel was a mean of 0.908 cm² ie larger, while non-CTS patients had a mean of 0.797 cm² inside the tunnel. The transverse carpal ligament (TCL) measured a mean of 0.0988 cm in the CTS group (ie thinner) and 0.1058 cm in the non-CTS group. Median nerve mobility at equal to or less than one tendon width was 80% in pregnant women with CTS and 92.1% for those without. No fluid was present within the carpal tunnel of all patients. The results were statistically not significant. Conclusion: Ultrasonographic evidence in pregnant women with CTS shows a larger median nerve, a more mobile median nerve and a less thick transverse carpal ligament. There is absence of fluid retention and synovitis ruling out extrinsic compression of the median nerve as cause of CTS in pregnancy.
ABSTRACT
We report a case of 50 years female suffering from compression neuropathy due to ossification of ligamentum flavum. This ossification of ligamentum flavum usually presents with neuropathy in the setting of thoracic spinal stenosis.
ABSTRACT
Perilunate dislocation represents approximately 3% of all carpal injuries and is diagnosed late in 25% of cases. Neglected perilunate dislocation accompanies many complications. Multiple flexor tendon rupture is a very rare complication of neglected perilunate dislocation. Three cases have been reported in the English literatures. No case has been reported in Korean literature. We report on a case of multiple flexor tendon ruptures with compressive neuropathy of median and ulnar nerve caused by neglected volar perilunate dislocation.

ABSTRACT
Acupuncture has been widely used to treat a variety of disease and symptoms. But various complications have been reported. Among them, peripheral nerve injuries have been reported less frequently than other complications. The purpose of this report is to describe what we believe to be the first case of delayed superficial and deep peroneal nerve compressive neuropathy caused by fibrotic mass formed by neglected broken acupuncture needle.

Hypoglossal nerve injury is an uncommon complication following endotracheal intubation. A transoral procedure including endotracheal intubation may result in hypoglossal nerve compression at the lateral margin on the hyoid bone and inner mandibular margin at the tongue base. A 50-year-old patient undergoing rotator cuff repair developed a transient unilateral postoperative hypoglossal nerve injury following uncomplicated endotracheal intubation for general anesthesia. The following day the patient complained of difficulty with tongue movement and buccal manipulation of food, and had slurred speech. An electrophysiologic assessment confirmed a diagnosis of unilateral hypoglossal nerve palsy. The symptoms resolved spontaneously and completely by 6 weeks. The possible etiology of the injury is discussed, and related literatures are reviewed.

PURPOSE: The aim of this study was to develop a model for chronic nerve compression in a rat and a model reproducing a normal anatomical narrow portion that lies in the course of the peripheral nerve. MATERIALS AND METHODS: Male Sprague-Dawley rats were used. A 5 mm tendinous band was made from the patellar tendon harvested from each rat and placed around the sciatic nerve. In order to determine the degree of compression, a series of internal diameters of the band (0.2 mm smaller than (group I), same as (group II), and 0.2 mm (group III), 0.4 mm (group IV) and 0.6 mm greater (group V) than the diameter of sciatic nerve) were used. The rats were evaluated at 1, 2, 3, 4, and 6 months after banding using an electroneurophysiologic study, a pathohistologic study, and the morphometric nerve fiber analysis. RESULTS: In groups III and IV the morphometric findings showed statistically significant compressive changes in the periphery after 3 and 4 months, respectively and revealed significant changes in both the periphery and central portion at 6 months (p<0.05). In group V, the measurements and histologic findings were almost identical to the control group at 6 and 10 months. The nerve electrophysiologic study showed significant compressive changes at 6 months in groups III and IV (p<0.05). In the group V, the measurements were similar to those of the normal control. CONCLUSION: Groups III and IV appear to be a reliably reproducible chronic nerve compression model while excluding the possibility of foreign body reactions. In addition, group V appears to be a reliable model of a normal anatomical narrow portion that lies in the course of the peripheral nerve.

Behcet's disease is generally recognized as a chronic multi-system disease. Approxymately 8% of patients with Behct's disease will have serious vascular compilcations which is called vasculo-Behcet's disease. A male patient of 41 year old was admitted to our clinic, complaining pain of left popliteal fossa and hypesthesia of left lower leg. A popliteal aneurysm was found. Resection of the aneurysm and a saphenous vein graft were successfully performed. Neuropathy disappeared after the surgery. Aneurysms in Behcet's disease mainly appear in major arteries, and rarely in peripheral arteries. Compression neuropathy in the popliteal aneurysm of Behcet's disease has been rarely reported. Early resection of aneurysm before completion of neuropathy is recommended for succsessful outcome.
