Glomus Tumor of the Lower Extremity Previously Misdiagnosed as Complex Regional Pain Syndrome in Close Proximity to a Myxofibrosarcoma: A Case Report
J Am Acad Orthop Surg Glob Res Rev. 2022 Jul 6;6(7). doi: 10.5435/JAAOSGlobal-D-21-00311. eCollection 2022 Jul 1.ABSTRACTComplex regional pain syndrome (CRPS) is a potentially devastating condition that can result in severe psychological and social morbidity. It is a diagnosis of exclusion, and other pathologic entities must be ruled out first. Glomus tumors are exquisitely painful benign vascular tumors that are most common in the hand and are rarely found in the lower extremity. Here, we present a case of a patient who developed a focus of severe anterior knee pain and tenderness a few months after a car accident that ha...

Structural and Functional Changes in the Cerebellum and Brainstem in Patients with Benign Paroxysmal Positional Vertigo
AbstractBenign paroxysmal positional vertigo (BPPV) is one of the most common peripheral vestibular diseases. Since the peripheral vestibular system connects with the cerebellum via the brainstem, repeated episodic vertigo may result in progressive structural and functional changes in the cerebellum and brainstem. In the present work, voxel-based morphometry (VBM) of T1-weighted images and resting-state functional magnetic resonance imaging (fMRI) in 32 patients with BPPV and 32 matched healthy controls were used to assess cerebellar and brainstem anatomical and spontaneous resting-state brain activity alterations associat...

Management of CRPS secondary to preganglionic C8 nerve root avulsion: A case report and literature review.
Conclusion: A preganglionic cervical nerve root avulsion should not be a contraindication for a stellate ganglion block in a patient with established CRPS. PMID: 33024600 [PubMed]

Implications of the putamen in pain and motor deficits in complex regional pain syndrome
Complex regional pain syndrome (CRPS) develops after-limb injury, with persistent pain and deficits in movement frequently co-occurring. The striatum is critical for mediating multiple mechanisms that are often aberrant in CRPS, which includes sensory and pain processing, motor function, and goal-directed behaviors associated with movement. Yet, much remains unknown with regards to the morphological and functional properties of the striatum and its subregions in this disease. Thus, we investigated 20 patients (15 female, age 58 ± 9 years, right-handed) diagnosed with chronic (6+ months of pain duration) CRPS in the right ...

Acupuncture for Post-stroke Shoulder-Hand Syndrome: A Systematic Review and Meta-Analysis
Conclusions: Acupuncture therapy seems effective for motor function, pain relief and activities of daily living in stroke patients with mild SHS, when it is used in combination with rehabilitation. The low certainty of evidence downgrades our confidence in making recommendations to clinical practice. Introduction Shoulder-hand syndrome (SHS) is a common condition among people who have had a stroke, with its reported prevalence ranging from 12% to 49% (1, 2). The main symptoms of SHS include pain, hyperalgesia, joint swelling and limitations in range of motion (ROM) (3). Post-stroke SHS is also named type I complex ...

A rare cause of type 1 complex regional pain syndrome: Osteoblastoma of the talus.
We report a 14-year-old boy who presented with pain in the left foot and ankle for about 9 months. The clinical symptoms of the patient suggested complex regional pain syndrome (CRPS). The radiographs and magnetic resonance imaging studies ravealed a bone tumor in the talus, consistent with an osteoblastoma. The patient underwent operative treatment with curettage and grafting. The complaints of the patient completely resolved by 6 months after surgery, and there was no recurrence at the postoperative 23th month follow-up. PMID: 30100373 [PubMed - as supplied by publisher]

Complex regional pain syndrome type II after cervical transforaminal epidural injection: A case report
We report a case of a 61-year-old patient who developed complex regional pain syndrome (CRPS) type II after a cervical transforaminal epidural steroid injection (CTESI). Patient concerns: The patient developed sudden-onset severe pain and swelling of his upper right limb after a cervical transforaminal epidural injection. Diagnoses: On physical examination, the patient's symptoms and signs corresponded to the Budapest criteria for CRPS. Cervical magnetic resonance imaging and laboratory tests were performed to rule out other causes. An electrodiagnostic study revealed right C6/7 radiculopathies. A three-phase bone sc...

Bone scintigraphy in patients with pain.
Authors: Shin SH, Kim SJ Abstract Nuclear medicine imaging is widely used in pain medicine. Low back pain is commonly encountered by physicians, with its prevalence from 49% to 70%. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually used to evaluate the cause of low back pain, however, these findings from these scans could also be observed in asymptomatic patients. Bone scintigraphy has an additional value in patients with low back pain. Complex regional pain syndrome (CRPS) is defined as a painful disorder of the extremities, which is characterized by sensory, autonomic, vasomotor, and trophi...

Abnormal brain responses to action observation in complex regional pain syndrome
Patients with complex regional pain syndrome (CRPS) display various abnormalities in central motor function, and their pain is intensified when they perform or just observe motor actions. Here, we examined the abnormalities of brain responses to action observation in CRPS. We analyzed 3-T functional magnetic resonance images from 13 upper-limb CRPS patients (all females, ages 31 –58 years) and 13 healthy, age- and sex-matched control subjects. The functional magnetic resonance imaging data were acquired while the subjects viewed brief videos of hand actions shown in the first-person perspective.

An exploration into the cortical reorganisation of the healthy hand in upper-limb complex regional pain syndrome
Conclusion Our exploration did not yield evidence of any relationship between the size of the healthy hand representation in S1 and the severity of functional impairment of the CRPS-affected hand, relative to overall hand use or to self-efficacy. There was also no evidence of an association between the size of the healthy hand representation in S1 and pain duration. The enlarged S1 representation of the healthy hand does not relate to self-reported function and impairment in CRPS. Implications While this study had a hypothesis-generating nature and the sample was small, there were no trends to suggest compensatory use as ...

(309) Evoked brain response to fearful faces in pediatric complex regional pain syndrome (CRPS)
Complex regional pain syndrome is a chronic neuropathic pain disorder that effects many pediatric pain patients after injury, and pathways and causes have yet to be well understood. Fear of pain in these children has presented as a major challenge, which can vastly limit progress in treatment. We seek to better understand the neural underpinnings of fear processing in pediatric CRPS patients using functional magnetic resonance imaging (fMRI). We measured the evoked brain responses of youth, ages 9-20, at two time points (Time 1: admission to intensive pain rehabilitation; Time 2: two months post-discharge) using an unmaske...

Rapid treatment-induced brain changes in pediatric CRPS
Abstract To date, brain structure and function changes in children with complex regional pain syndrome (CRPS) as a result of disease and treatment remain unknown. Here, we investigated (a) gray matter (GM) differences between patients with CRPS and healthy controls and (b) GM and functional connectivity (FC) changes in patients following intensive interdisciplinary psychophysical pain treatment. Twenty-three patients (13 females, 9 males; average age ± SD = 13.3 ± 2.5 years) and 21 healthy sex- and age-matched controls underwent magnetic resonance imaging. Compared to controls, patients had reduced GM in ...
