REVIEW
Christophe Mathoulin, Mathilde Gras
Dorsal and volar wrist ganglions are benign tumors; most of them are asymptomatic. They can disappear spontaneously. Arthroscopic resection can be performed for pain or cosmetic concern. Dorsal ganglion is more common (70%). The hypothesis of the origin is the result of mucoid dysplasia in association with intracapsular and extrasynovial ganglia that occur at the level of the dorsal scapholunate complex. Volar wrist ganglia are less common (20%) and occur mainly in the radiocarpal joint. They are due to capsular destruction at the volar insertion of the SL ligament and arise from the interval between radio scaphocapitate and long radiolunate ligament...

Voluntary movements require control of multiple kinematic parameters, a task carried out by a distributed brain architecture. However, it remains unclear whether regions along the motor system encode single, or rather a mixture of, kinematic parameters during action execution. Here, rapid event-related functional magnetic resonance imaging was used to differentiate brain activity along the motor system during the encoding of movement amplitude, duration, and speed. We present cumulative evidence supporting preferential encoding of kinematic parameters along the motor system, based on blood-oxygenation-level dependent signal recorded in a well-controlled single-joint wrist-flexion task...

We are interested in characterizing how brain networks interact and communicate with each other during voluntary movements. We recorded electrical activities from the globus pallidus pars interna (GPi), subthalamic nucleus (STN) and the motor cortex during voluntary wrist movements. Seven patients with dystonia and six patients with Parkinson's disease underwent bilateral deep brain stimulation (DBS) electrode placement. Local field potentials from the DBS electrodes and scalp EEG from the electrodes placed over the motor cortices were recorded while the patients performed externally triggered and self-initiated movements...

The aim of the present study was to treat intraosseous ganglia of the carpal bones with injectable bone cement grafting. Between January 2012 and December 2013, 4 patients (3 men and 1 woman) presenting with wrist pain and activity limitation were diagnosed with intraosseous ganglion of the carpal bones by radiography. The patients were treated with minimal invasive curettage and bone cement injection surgery. All patients were followed up for a mean time of 17 months (range, 12-22 months). The wrist pain was significantly reduced in all patients following surgery...

INTRODUCTION: Arthroscopic resection of dorsal wrist ganglia has become a well-accepted practice. However, there is a paucity of results on occult ganglia in the literature. The purpose of this study is to evaluate the subjective outcomes of occult dorsal wrist ganglion cysts resected arthroscopically, and to identify and examine intraarticular findings and relate them to pre-operative MRI findings and histologies. MATERIALS AND METHODS: In 39 patients, 40 wrists were treated with arthroscopic resection of an occult dorsal wrist ganglion...

Ultrasonography facilitates dynamic, real-time evaluation of bones, joints, tendons, nerves, and vessels, making it an ideal imaging modality for hand and wrist conditions. Ultrasonography can depict masses and fluid collections, help locate radiolucent foreign bodies, characterize traumatic or overuse tendon or ligament pathology, and help evaluate compressive peripheral neuropathy and microvascular blood flow. Additionally, this modality improves the accuracy of therapeutic intra-articular or peritendinous injections and facilitates aspiration of fluid collections, such as ganglia...

Dedicated pairs of isometric wrist flexion tasks, with and without visual feedback of the exerted torque, were designed to target activation of the CBL and BG in healthy subjects during functional magnetic resonance imaging (fMRI). Selective activation of the cerebellum (CBL) and basal ganglia (BG), often implicated in movement disorders such as tremor and dystonia, may help identify pathological changes and expedite diagnosis. A prototyped MR-compatible wrist torque measurement device, free of magnetic and conductive materials, allowed safe execution of tasks during fMRI without causing artifacts...

A ganglion cyst (GC) is a mucinous or gelatinous-filled benign tumor overlying a joint or tendon sheath, which commonly arises in the dorsal and volar wrist side but may occur anywhere in the body. Although cystic lesions around the knee are common, the occurrence of GCs are rare. Ganglia may arise from intra or extra-articular, soft tissue, intraosseous, or periosteal location. Symptoms may vary according to the size and location. After the more frequent performance of magnetic resonance imaging for the assessment of a knee joint, the number of incidental, asymptomatic lesions have been increasingly diagnosed...

Parkinson's Disease (PD) patients often need Deep Brain Stimulation (DBS) surgery when they become intolerant to drugs or these lose efficiency. A stimulation electrode is implanted in the basal ganglia to promote the functional control of the deregulated dopaminergic motor pathways. The stimulation target is defined by medical imaging, followed by electrophysiological inspection for fine electrode position trimming and electrical stimulation tuning. Intra-operative stimulation of the target and the evaluation of wrist rigidity allows to choose the stimulation parameters which best alleviate PD symptoms without side effects...

INTRODUCTION: Segawa disease (SD), an autosomal dominant dopa-responsive dystonia with marked diurnal fluctuation, can be clinically classified into the postural dystonia type (SD-P) and action dystonia type (SD-A). Compared to SD-A, SD-P has an earlier onset and is characterized by postural dystonia. In SD-A, along with postural dystonia, dystonic movements appear in late childhood. To evaluate the differences between these two types of SD, we studied the gating of SEPs, which is useful to investigate sensory-motor integration and might be one of the methods to detect the thalamo-cortical involvement...
