Ultrasound-Guided Percutaneous Peripheral Nerve Stimulation for the Treatment of Chronic Intractable Pain Originating From a Lipofibromatous Hamartoma of the Median Nerve.

This case report presents an application of peripheral nerve stimulation to the median nerve to treat a patient with intractable pain due to a lipofibromatous hamartoma of the left upper extremity. Ultra high-frequency ultrasound was used to determine the boundaries of the hamartoma. The patient then underwent an ultrasound-guided implantation of 2 stimulator electrodes distal to the elbow along the median nerve with stimulation coverage achieved at 1.2 and 1.4 mA, respectively. After an uneventful procedure, the pain score immediately decreased from 9 out of 10 to less than 6 on a numeric rating scale. Two weeks after the procedure, the patient reported substantial pain relief, with an average pain level of 5 to 6 out of 10. Twelve months after implantation, the patient maintained significant pain relief, rating her average pain level as a 4 to 6 out of 10. Placement of a percutaneous peripheral nerve stimulator was safe and effective with no adverse events being reported at the 12-month follow-up.

Defining Outcomes Following Distal Radius Fractures: Correlation of Function, Pain, and Hand Therapy Utilization.

Background Distal radius fractures (DRF) is one of the most common fractures in clinical practice. Our objective was to study the role of early hand therapy and its impact on pain and return to daily activities. Methods The charts of patients with DRFs seen between January 2016 and November 2017 in the Hand Center of Mayo Clinic Florida were reviewed retrospectively. Forty-nine patients with DRFs who met inclusion criteria were included in the analysis. The variables collected included: age, gender, side of the fracture, surgery vs non-surgery, time to start hand therapy, number of visits, shortened disabilities of the arm, shoulder, and hand (QuickDASH) initial and discharge scores, and visual analog scale (VAS) initial and discharge. Results The patients' mean age was 67.90 years, (standard deviation (SD) 14.54), 38 (77.6%) were female, 28 (57.1%) had a right DRF, 21 (42.9%) had a left DRF, 38 (77.6%) had no surgery, 11 (22.4%) had surgery. The mean time from fracture to therapy is 32.41, (SD 24.13) days, and the mean total number of visits is 6.20 (SD 3.49). We noticed a statistically significant difference between the initial QuickDASH (59.27, SD 16.93) compared to the discharge QuickDASH (24.08, SD 12.77) (P-value <.001); and initial VAS (3.57, SD 1.71) with a discharge VAS (1.33, SD 0.97) (P-value <.001).  Conclusion This retrospective study found a statistically significant reduction in the QuickDASH and VAS scores after six hand therapy visits. The results suggest that early rehabilitation interventions lead to improvements in pain and return to daily activity following DRF.

Use of Ultra-high-frequency Ultrasound on Diagnosis and Management of Lipofibromatous Hamartoma: A Technical Report.

Lipofibromatous hamartoma (LFH) is a rare, benign tumor found in the peripheral nerves which is challenging to diagnose. We present a case report of the use of ultra-high-frequency ultrasound (UHFUS) on a patient with an LFH to provide valuable information not available on other imaging modalities regarding tumor invasion of the nerve fascicles.

Continuous regional anesthesia before surgical peripheral sympathectomy in a patient with severe digital necrosis associated with Raynaud's phenomenon and scleroderma.

BACKGROUND AND OBJECTIVE: Digital ischemia and necrosis caused by Raynaud's phenomenon in patients with connective tissue diseases may not respond to medical therapy and may have major adverse effects on quality of life. We describe the use of continuous ambulatory regional anesthesia for diagnosis and treatment before peripheral sympathectomy in a patient with secondary Raynaud's phenomenon. CASE REPORT: A 55-year-old man with progressive systemic sclerosis and secondary Raynaud's phenomenon presented with severe pain and digital necrosis that were refractory to maximal medical treatment and thoracic sympathectomy. Continuous ambulatory regional analgesia increased digital temperature from 32.3 degrees C at baseline to 34.4 degrees C after 80 minutes. An increase in digital flow was documented by Doppler ultrasound measurements made ventrally at the point of greatest pulsation of the radial artery. Subsequent peripheral sympathectomy resulted in restoration of nutrient flow with healing of ulcers and alleviation of pain. CONCLUSIONS: Continuous ambulatory regional anesthesia appears effective as a treatment bridge for vasospasm and ischemia associated with secondary Raynaud's phenomenon. The enhancement of peripheral blood flow achieved with the regional anesthetic technique suggests that surgical peripheral sympathectomy may provide long-term benefits.

Biopsy of hand, wrist, and forearm tumors.

This article describes three biopsy methods currently used for treating masses arising in the hand, wrist, and forearm: open biopsy, fine needle aspiration, and core needle biopsy. The forearm, wrist, and hand comprise a complex and diverse anatomic region, and biopsy is emphasized as the most important element in the diagnosis of the musculoskeletal tumor. Biopsy methods for assessing true neoplasms, bony protuberances, cysts,infection and abscesses, foreign bodies, reactive granulomas, tenosynovial proliferation,and skin and fascial lesions are discussed.

Treatment of distal radius fractures with external fixation: technical considerations for rehabilitation.

Wrist external fixation with or without K-wire stabilization has been shown to be a reliable treatment method for unstable fractures of the distal radius. The technique of external fixation of the wrist has been historically based on the premise that fracture reduction can be achieved and maintained using the principles of ligamentotaxis. It is now well recognized that sustained longitudinal traction applied with a wrist external fixator can lead to complications. This review outlines the authors' preferred technique of using the external fixator as a neutralization device rather than as a traction device. The absence of sustained radiocarpal traction during distal radius fracture healing may facilitate postoperative rehabilitation.

The use of routine wrist radiography is not useful in the evaluation of patients with a ganglion cyst of the wrist.

The purpose of this study was to evaluate the cost-effectiveness of routine wrist radiography in the evaluation of patients with a wrist ganglion. In the setting of a University-based hand surgery practice, 103 consecutive patients with a dorsal or volar wrist ganglion underwent posteroanterior, lateral, and oblique radiographs of the involved wrist. There were 24 men and 79 women with an average age of 34 years (range 4-67 years). A retrospective review of the medical records was performed. Abnormalities on plain radiographs were noted in only 13 patients (13%). Findings included six cases of thumb carpometacarpal joint arthritis and one case each of an enchondroma, congenital distal radioulnar joint (DRUJ) anomaly, DRUJ degenerative changes, intraosseous ganglion, carpal boss, radiocarpal arthritis, and thumb metacarpophalangeal joint osteoarthritis. In only one case (1%) did the findings alter the management. At our institution, the professional and technical charge for three views of the wrist is $172. This confers a cost of $17,716 per therapeutically significant finding in our series. We conclude that routinely performing wrist radiography is not cost-effective in the evaluation and treatment decision-making process in patients with a wrist ganglion.
