Osteoid osteoma is a rare clinical entity often mistaken for osteomyelitis, enchondroma, osteochondroma and other bony pathologies. Cardinal features include localized swelling and nocturnal pain often relieved by nonsteroidal antiinflammatory drugs. Definitive treatment requires surgical removal of the lesion by curettage or en bloc excision. The following case report details the diagnosis and...

Large segmental bone defects of the phalanges reportedly have been treated with free vascularized grafts from the hand, foot, or knee, or with nonvascularized grafts from the iliac crest. A nonvascularized structural corticocancellous graft from a local site would be advantageous. The olecranon has been used as a source of both cancellous and corticocancellous graft. The authors describe a uniq...

Primate hands display a major selective compromise between locomotion and manipulation. The thumb may or may not participate in locomotion, but it plays a central role in most manipulative activities. Understanding whether or not the last common ancestor of humans and Pan displayed extant-ape-like hand proportions (i.e., relatively long fingers and a short thumb) can be clarified by the analysi...

BACKGROUND Measurement of skin involvement is essential for diagnosis and prognosis in systemic sclerosis. Assessment by palpation skin score is the current method. OBJECTIVE To explore high frequency ultrasound as an objective method to improve skin characterisation by combining measurements of skin thickness and echogenicity. METHODS Skin thickness and echogenicity were measured at the pr...

Background: Both primary and secondary tumors can develop in distal phalanx of the hand presenting as lytic lesions. The presence of a lytic lesion in the distal phalanx has been a dilemma making the differential diagnoses, prognosis, and treatment of these lesions challenging. Objectives: This study was designed to evaluate the patients who were presented with a lytic lesion in their distal ph...

Phalangeal curvature has been widely cited in primate functional morphology and is one of the key traits in the ongoing debate about whether the locomotion of early hominins included a significant degree of arboreality. This study examines the biomechanics of phalangeal curvature using data on hand posture, muscle recruitment, and anatomical moment arms to develop a finite element (FE) model of...

The mechanism of injury in dorsal dislocations is usually PIP joint hyperextension combined with some degree of longitudinal compression, which frequently occurs in ball-handling sports if the tip of the digit is hit with the ball. In the majority of cases, dorsal dislocation produces a soft tissue or bone injury to the distal insertions of the three-dimensional ligament-box complex. The greate...

The proximal phalangeal base is the most commonly fractured hand bone in children. Such fractures are rarely reported as irreducible due to flexor tendon entrapment. Here, we describe a patient who sustained a malunited fracture on the right fifth finger proximal phalanx with flexor tendon entrapment after treatment with closed reduction with K-wires fixation. A 13-year-old patient came to the ...
