OBJECTIVE We planned this study to evaluate the role of bone scintigraphy in patients with suspected carpal fracture and normal or suspicious radiographs following carpal injury. METHODS Three-phase bone scintigraphy using Tc-99m-MDP was performed on 32 patients with negative radiographs but clinically suspected fracture at two weeks after the trauma. Focally increased radiopharmaceutical upt...

PURPOSE As long as the neuromuscular stabilizers are intact, a lesion of the scapholunate ligament may or may not progress to a carpal instability. The mechanisms by which the muscles compensate this defect are not very well known. We designed an experimental study with the aim of clarifying these mechanisms. MATERIAL AND METHOD Using 10 fresh wrists, with no pre-existing lesions, we studied ...

This study involves the evaluation of pre-purchase radiographic studies of South African Thoroughbred yearlings. Radiographic changes were recorded and compared with similar international studies. The study differs from other studies in that a lower prevalence of pedal osteitis (1.26%), dorsal osteochondral fragmentation of the metatarsophalangeal joint (1.60%), distal metacarpal sagittal ridge...

MRI is a medical imaging modality that works by utilizing hydrogen atoms in the body. Imaging does not use ionizing radiation but uses an external magnetic field. able to provide good soft tissue contrast based on nature of tissue. The wrist joint complex consisting several bones and joints. consist including distal radius ulna, 8 carpal bones, proximal part consists 5 metacarpal bones. This ty...

SCAPHOID FRACTURES account for 71% of carpal bone fractures, and between 2% and 7% of all orthopaedic fractures (Nishihara 2000). This type of injury also accounts for one in every 10,000 attendances annually in UK emergency departments (EDs) (Tai and Ramachandran 2005). Between 5% and 12% of scaphoid fractures are related to other fractures (Malik et al 2010). The scaphoid is one of the eight ...

PURPOSE According to current recommendations in diagnostics of rheumatoid arthritis (RA), Magnetic resonance (MR) images of wrist joints are used to evaluate three main signs of RA: synovitis, bone edema and bone erosions. In this paper we present an efficient method for segmentation of 15 bones present on MR images of the wrist which is inevitable for future computer-assisted diagnosis system ...

Radial polydactyly, the most common digital duplication in Asian and white populations, has a wide range of manifestations. Its classification is useful for planning and assessing surgical treatment. Our patient had four thumbs, duplicated radial carpal bones, and a bifurcated radius. This presentation is not covered by any of the current classifications. To the best of our knowledge, this is t...

The stability of the wrist during motion and interrelated motions depends on the capsuloligamentous integrity and the contact surface contours of the carpal bones [1]. Perilunate fracture dislocations (PLFD) are high-energy injuries, produced by wrist hyperextension. It can be palmar or dorsal. Palmar dislocation is extremely rare and result from a fall on the dorsum of the flexed wrist. This i...

An asymptomatic atypical U shaped cleft hand has been found in a 21-year-old lady attending OPD. On digital skiagram it was found that central digits were absent with remnants of bases of the metacarpals, which have fused with the carpal bones. Moreover, the scaphoid and trapezium had fused to form a single mass. There was no other anomaly in other limbs, so far searched for. An endeavor has be...

To date the diagnosis of carpal instabilities due to ligament lesions relies on a qualitative examination of the patient’s wrist. This paper presents a novel system where sequences of magnetic resonance images are automatically analysed to measure the motion of seven wrist bones. Resulting motion graphs provide a quantitative basis for diagnostic as well as scientific purposes. As the imaging m...
