Ultrasound and magnetic resonance findings and correlation in hemiplegic patients with shoulder pain.

BACKGROUND: The aim of this study was to evaluate the ultrasonography (US) and MRI findings in hemiplegic patients with shoulder pain and investigate the correlation between them. It is not possible for these patients to fully perform active range of motion (ROM) and stress tests, so imaging methods take center stage in diagnosis and treatment planning. MATERIALS AND METHODS: A total of 68 hemiplegic patients with shoulder pain attending the inpatient rehabilitation program were included in the study. MRI and US results from the patient files were recorded. The frequency of each pathology identified by US and MRI was determined. The distribution of MRI and US findings was investigated to see whether there was a statistical difference between the correlation of MRI and US results. RESULTS: The mean (SD) age of the patients was 63.7 (8.3) years and the mean (SD) duration of hemiplegia was 49 (8.9) days. According to the MRI results, glenohumeral and acromioclavicular joint degeneration was found in 77.9% and 79.7% of the patients, respectively; subacromial-subdeltoid bursitis in 80.9%; fluid increase in the joint space in 41.2%; supraspinatus tendinitis in 36.8%; and supraspinatus partial rupture in 33.8%. Shoulder US findings were supraspinatus tendinitis in 54.4%, acromioclavicular joint degeneration in 26.5%, bicipital tendinitis in 20.6%, and subacromial-subdeltoid bursitis in 19.1%. There was a statistically significant difference between MRI and US findings. The results were not compatible with each other (P ≯ .05), and these findings were not consistent with each other since the kappa coefficient was under 0.40 for all these results. CONCLUSION: Although US is recommended as the first method in determining shoulder pathologies in hemiplegic patients, we suggest that MRI should be used as the first choice in hemiplegic patients with shoulder pain. MRI and US findings were not consistent, and US is dependent on the experience of the operator. MRI should be the first choice in cases where the diagnosis will affect the treatment choice due to the lack of correlation between US and MRI findings.

Diabetic muscular infarct: an unusual cause of extremity pain and dysfunction.

Diabetic muscular infarct (DMI) is a rare condition, which begins with acute onset of extremity pain and swelling. Patients usually have long-standing disease and poorly controlled diabetes mellitus (DM). Thigh muscle group is the most commonly involved side, while lower leg involvement is rare. We represent herein a 22-year-old patient with type I DM who admitted to our outpatient clinic due to painful swelling of the left leg. In physical examination, anterior left leg was painful and firm on palpation; there was diffuse swelling extending to the knee and ankle with mild local fever and redness. T2-weighted MRI demonstrated hyperintensity in left leg muscles. A biopsy confirmed the diagnosis of DMI. She was treated with glucose regulation, analgesics, antiplatelet treatment and rest. At her 6 months, recurrence of DMI was observed. DMI should be considered in diabetic patients with extremity pain and swelling. Treatment plan should include the regulation of the blood glucose and evaluation of end-organ complications, analgesia, and bed rest.

Peripheral nerve involvement in a neurofibromatosis type 2 patient with plexiform neurofibroma of the cauda equina: a sonographic vignette.

We report a 20-year-old man with cauda equina syndrome and neurofibromatosis type 2. We discuss the role of sonographic and electromyographic evaluations in the management of our patient and suggest the use of sonographic imaging for visualization of peripheral nerve pathologic states, especially when involvement is widespread.

Cervical compression myelopathy: is fusion the main prognostic indicator?

OBJECT: A variety of factors may affect the neurological improvement in patients with cervical compression myelopathy (CCM) after surgery. The aim of this study was to report and discuss the prognostic factors in a group of patients with insufficient decompression of the spinal canal. METHODS: A prospective follow up and analysis of 20 consecutive patients with CCM treated between 2000 and 2002 was performed. All patients were surgically treated via an anterior approach, either by anterior cervical discectomy and fusion with instrumentation or by cervical corpectomy and fusion with instrumentation. The surgical results were examined using the modified Japanese Orthopaedic Asssociation disability scale, with reference to the findings of magnetic resonance imaging, computed tomography, and radiography. Seventeen patients (85%) experienced a 50% or more recovery rate as calculated using the Hirabayashi formula during the follow-up period (mean 32.5 months), despite a persistently narrow spinal canal and permanent or increased intramedullary high-intensity signal after surgery. CONCLUSIONS: Results of the study showed that patients with CCM benefited from anterior cervical discectomy and fusion with instrumentation or cervical corpectomy and fusion with instrumentation procedures despite insufficient decompression of the spinal canal. Fusion of the affected level(s) might be the reason for the acquired high recovery rates. The authors also conclude that the neurological improvement is not correlated with the reversal of or decrease in the intramedullary high-intensity signal change after surgery.

Isolated fibrosis/contracture of the rectus femoris muscle: diagnosis and follow-up with sonography.

Reported here is a 21-year-old female with isolated contracture of the rectus femoris muscle. Its possible relation to breech positioning, and the role of sonography for its diagnosis and close follow-up are discussed in the light of the relevant literature.
