Confirmatory needle placement technique for scalene muscle block in the diagnosis of thoracic outlet syndrome.

Scalene muscle block is often performed to assist with the clinical differentiation of primary sources of pain and weakness in the upper limb when the differential diagnosis includes thoracic outlet syndrome. This presentation offers a simple clinical method to assess needle placement in the scalene muscle before an injection of local anesthetic which, if properly placed, weakens the scalene muscle and often leads to temporary relief of symptoms associated with neurovascular compression. An appropriate scalene block response provides assistance with medical decision making.

Functional results of vertebral augmentation techniques in pathological vertebral fractures of myelomatous patients.

INTRODUCTION: This is a retrospective study to determine the effects of vertebroplasty and kyphoplasty on quality of life in multiple myeloma patients with spinal compression fractures. MATERIAL AND METHODS: Thirty-four patients with primary multiple myeloma were treated for symptomatic compression fractures between June 2003 and June 2005. Kyphoplasty was applied to 22 levels in 18 and vertebroplasty to 28 levels in 16 patients. The pain-related disability was evaluated for every single daily living activity using visual analog scale (VAS) over 10 points. (pain at rest, walking, sitting-standing, taking a shower and wearing clothes). (This evaluation is performed to every patient with degenerative disorders of the spine upon admission to our clinic.) Overall VAS scores were evaluated over 50 points (0 minimum, 50 maximum) preoperatively, at postoperative six weeks, six months and at one year prior to taking analgesics. The amount of analgesic use was recorded. Data was analyzed statistically using variance analysis, Friedman's multiple comparison test and Student's t test. RESULTS: The mean overall pain score in the kyphoplasty group decreased from a preoperative value of 36 to 12.13 at the sixth postoperative week, to 8.63 at the sixth month and to 9.72 at one year. (p<0.001). The mean overall pain score in the vertebroplasty group decreased from a preoperative value of 37.83 to 15.33 at the sixth postoperative week, to 12.17 at sixth months and to 13.47 at one year. (p<0.001). Student's t test was used to analyze the percentage of differences in overall pain score. Difference between groups was not statistically significant at the sixth week (p=0.106) but was statistically significant both at the sixth month (p=0.024) and at one year (p=0.027) in favor of kyphoplasty group. No secondary collapse was observed in adjacent levels in both groups. There were no intrapostoperative neurologic/pulmonary complications in both groups. Analgesics usage significantly decreased in both groups. CONCLUSION: In multiple myeloma, when pathological spinal compression fractures cause intractable pain and are unresponsive to conservative treatment, both vertebroplasty and kyphoplasty are effective in increasing quality of life and decreasing pain.

Rare case of intraosseous lipoma with proximal femoral localization causing cortical expansion.

Intraosseous lipoma has a 1% incidence among the primary tumors of the bone, and it frequently occurs in the calcaneous. As it is rare, it may be mistaken for nonossifying fibroma, aneurismal bone cyst, simple bone cyst, bone infarct and chondroid tumors. Intraosseous lipomas are usually followed up conservatively due to their spontaneous involution. However, surgery is required in the presence of fracture risk, malignant transformation potential and/or extensive pain. Herein we report a case with intraosseous lipoma involving the intertrochanteric femur and the collum femoris, causing cortical expansion. This presentation is extremely unusual for this type of tumor both in terms of localization and radiology. As the patient was symptomatic with extensive pain, we treated the patient by curettage and bone grafting.

Acute gangrene that developed in the fingers of the hand with arteriovenous fistule in a chronic hemodialysis patient.

Finger gangrene developing due to arterial occlusive disease in the upper extremity is a rare pathology. Although rare, it can especially be seen in patients undergoing chronic hemodialysis. Although there are no established reasons in the etiology of gangrene occurring in the hand following chronic hemodialysis, certain high-risk factors have been defined. Awareness of these high-risk factors is important in the prevention of these types of undesired complications with high morbidity rates. In our study, we report an acutely developed finger necrosis as well as the possible etiologic factors causing the necrosis and its treatment. The necrosis developed in the hand (where an arteriovenous fistule formed) of a 60-year-old patient in menopause, with osteoporosis, diabetes, hypertension, and who was undergoing hemodialysis due to an eight-year history of end-stage renal disease.

Eye problem following foot surgery--abducens palsy as a complication of spinal anesthesia.

BACKGROUND: Paralysis of abducens nerve is a very rare complication of lumbar puncture, which is a common procedure most often used for diagnostic and anesthetic purposes. CASE REPORT: A 38-year-old man underwent surgery for a left hallux valgus while he was under spinal anesthesia. On the first postoperative day, the patient experienced a severe headache that did not respond to standard nonsteroidal anti-inflammatory medication and hydration. During the second postoperative day, nausea and vomiting occurred. On the fourth postoperative day, nausea ceased completely but the patient complained of diplopia. Examination revealed bilateral strabismus with bilateral abducens nerve palsy. His diplopia resolved completely after 9 weeks and strabismus after 6 months. CONCLUSION: Abducens palsy following spinal anesthesia is a rare and reversible complication. Spinal anesthesia is still a feasible procedure for both the orthopaedic surgeon and the patient. Other types of anesthesia or performing spinal anesthesia with smaller diameter or atraumatic spinal needles may help decrease the incidence of abducens palsy. Informing the patient about the reversibility of the complication is essential during the follow-up because the palsy may last for as long as 6 months. Special attention must be paid to patient positioning following the operation. Recumbency and lying flat should be accomplished as soon as possible to prevent cerebrospinal fluid leakage and resultant intracranial hypotension. This becomes much more important if the patient has postdural puncture headache.

Recalcitrant scoliosis in Proteus syndrome.

Proteus syndrome is a rare congenital condition with various clinical features such as hemihypertrophy, macrodactyly, subcutaneous masses, brain-like hyperplasia of the soles and/or palms, epidermal naevi and scoliosis with other mesodermal malformations. Multifocal overgrowth can affect various tissues causing severe functional and cosmetic disability, but intellectual and language development are mostly normal. Orthopaedic problems include macrodactyly, hindfoot deformity, limb length inequality, genu valgum and scoliosis. Usually, scoliosis does not respond to bracing, and surgical intervention may be required. Despite surgical correction, instrumentation and fusion, progression of deformity can occur. The authors describe a case with a Th7-L2 scoliosis, which completely relapsed, 20 months after posterior instrumented fusion. Surgery should not be undertaken lightly, given the abnormal growth potency typical for Proteus syndrome.
