The vast majority of soft tissue mass lesions of the wrist and hand are benign [1, 2]. In practice, the most common lesions encountered are ganglia. The most frequently seen solid masses include giant cell tumours of tendon sheath (GCTTS), lipomas, Dupuytrens contractures, nerve sheath tumours, glomus tumours, haemangioma/vascular malformations and synovial pathology. In general MRI is unable t...

OBJECTIVE To evaluate a low field dedicated extremity MRI unit for detection of bone erosions, synovitis, and bone marrow oedema in wrist and metacarpophalangeal (MCP) joints, with a high field MRI unit as the standard reference. METHODS In 37 patients with RA and 28 healthy controls MRI of the wrist and 2nd-5th MCP joints was performed on a low field MRI unit (0.2 T Esaote Artoscan) and a hi...

BACKGROUND Some cadaveric studies have reported the role of the distal oblique bundle (DOB) in the distal radioulnar joint stability. We aimed to determine whether the presence of the DOB can be identified and its thickness can be measured in magnetic resonance imaging (MRI) examinations. METHODS We retrospectively reviewed 468 wrist and forearm MRIs. Inclusion criteria were wrist or forearm ...

A 16-year-old boy presented with left wrist pain of 8 months’ duration. There was a remote history of a hyperextension injury to the wrist while weight lifting. He denied all constitutional symptoms. He had taken NSAIDs intermittently with no resolution of symptoms. He was an otherwise healthy adolescent with no significant medical history. His family history was noncontributory. The patient ha...

Subject-specific musculoskeletal models require accurate values of muscle moment arms. The aim of this study was to compare moment arms of wrist tendons obtained from non-invasive magnetic resonance imaging (MRI) to those obtained from an in vitro experimental approach. MRI was performed on ten upper limb cadaveric specimens to obtain the centrelines for the flexor carpi radialis (FCR), flexor ...

BACKGROUND Our aim is to study the accuracy of emergency medicine (EM) physician-performed, bedside ultrasonography (BUS) in patients with clinical suspicion of scaphoid fracture and normal radiographs. METHODS From January to December 2011, an EM physician used BUS to prospectively evaluate patients presenting to the emergency department (ED) with clinical suspicion of scaphoid fracture and ...

INTRODUCTION Scaphoid fracture is the most common fracture among the bones of the wrist. Plain radiography has a sensitivity of 59 to 79 percent for the diagnosis of scaphoid fracture after injury. Casting is done to avoid complications in patients with suspected fractures with normal radiography. Magnetic resonance imaging (MRI) has a sensitivity of 100% and a specificity of 99%. To avoid unne...

BACKGROUND Abnormal angulation of the lunate can be an indication of intercarpal pathology. On magnetic resonance images (MRIs) the lunate often looks dorsally angulated, even in healthy wrists. The tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. The primary aim of this study was to determ...

A 46 year old man presented with a growing mass over his wrist. Erosions of the triquetrum and hamate were present radiographically. Magnetic resonance imaging (MRI) showed a solid mass arising from the extensor carpi ulnaris tendon, which was T1 hypointense and isointense, T2 hypointense, and bloomed on gradient echo images. The preoperative diagnosis of giant cell tumour of the tendon sheath ...
