Nineteen weanling horses (average age = 147 d) were divided into exercised (EX; n = 10) and nonexercised (NEX; n = 9) groups, with age, sex and breed represented as equally as possible. The EX group was exercised on an automatic walker at a medium trot for up to 20 min, 5 d each week. Both groups were fed to meet 100% of their protein and 110% of their energy requirements (NRC, 1978). The EX gr...

Changes in metacarpal cortical bone mineral density (BMD) using digital x-ray radiogrammetry were studied in patients with early rheumatoid arthritis. After 1, 2, and 5 years, large BMD losses were found: -1.7%, -2.8%, and -5.6%, respectively. Elevated erythrocyte sedimentation rate and anti-cyclic citrullinated peptide levels were independent predictors of bone loss, indicating that the larges...

Comparison of subchondral bone density determined by quantitative computed tomography (CT) with gross and histopathologic changes have not been made in horses. The goal of this study was to determine if mean quantitative CT density and mean voxel standard deviation are associated with the presence and severity of osteochondral lesions in the palmar aspect of the distal third metacarpal bone in ...

This case report discusses the reconstruction of an entire thumb metacarpal after a diagnosis of giant cell tumor of bone. The patient underwent excision of the entire thumb metacarpal, followed by interposition of a tricortical iliac crest bone graft and metacarpophalangeal and carpometacarpal joint arthrodeses. This option allowed salvage of the patient's native thumb with functional use as a...

Among 227 chronic renal disease patients, micrometer caliper radiogrammetric measurements of the second metacarpal at midshaft showed the right metacarpal to be larger (with greater bone area) and with a greater cortical area than the left second metacarpal, both in 208 right-handed individuals and in 19 left-handed individuals. This direction of asymmetry was individually characteristic of the...

We present a rare case of stress fracture of the second metacarpal bone. A 14-year-old girl felt pain on the dorsal aspect of the right wrist without any history of major trauma, when she played a smash during a game of badminton. On the radiographs, periosteal reaction was detected on the ulnar aspect of the base of the second metacarpal bone. She was treated conservatively and she returned to...

Most stress fractures occur in the lower limbs and are rarely observed in the upper limbs. The second metacarpal is the longest of all the metacarpals and has the largest base, articulating with the trapezium, trapezoid, capitate, and third metacarpal. In athletes, stress fractures in non-weight bearing joints are uncommon. Therefore, the shaft of the second metacarpal bone undergoes a higher l...

The extensor carpi radialis longus (ECRL) muscle originates from the distal third of the lateral supracondylar ridge of the humerus, front of lateral intermuscular septum and from the lateral epicondyle of humerus. The tendon of ECRL along with extensor carpi radialis brevis (ECRB) passes through the second compartment of extensor retinaculum and inserts into the base of second metacarpal bone ...

BACKGROUND Osteoporosis is an age-related metabolic bone disease characterized by decreased mass and increased susceptibility to fracture. The literature suggests a relationship between oral bone loss and skeletal osteoporosis; however, most studies have produced conflicting results. The purpose of this study was to determine if a relationship exists among alveolar bone loss, alveolar bone dens...
