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...

OBJECTIVE To examine articular cartilage of the distal interphalangeal (DIP) joint and distal sesamoidean impar ligament (DSIL) as well as the deep digital flexor tendon (DDFT) for adaptive responses to contact stress. SAMPLE POPULATION Specimens from 21 horses. PROCEDURE Pressure-sensitive film was inserted between articular surfaces of the DIP joint. The digit was subjected to a load. Fin...

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...

In this study, a total of 16 Agile frog, Rana dalmatina species preserved in the ZDEU-COMU collection and collected from Çanakkale (4 ♂♂, 4 ♀♀) Kırklareli (7♂♂, 1♀) were examined to estimate their age relationship between body size using skeletochronology method. addition, both femora phalanx samples evaluated together. Sexual maturity ages found be 2-3 male female individuals populations. The ...

Laminitis is the second most common cause of death from disease in horses and causes great suffering animal economic emotional losses for people involved. Several therapeutic modalities are used treatment this disease, but their results not consistently described literature. In scenario, deep digital flexor (DDF) tenotomy a modality that can be chronic laminitis, releasing traction force DDF te...

a 3-year-old holstein-friesian cow was evaluated because of sudden onset of right hind limb lameness and pain with fetlock swelling for 2 days. based on the history, clinical index scores and computed radiographic examinations, the case was accurately diagnosed to be a severely comminuted fracture of the proximal phalanx. this cow was assigned for conservative treatment with external coaptation...

triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. in this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. the patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. surgical procedure for ...

Dorsally angulated proximal phalanx fractures have always presented a difficulty for treatment. A variety of options for treatment have been tried in the past, many of these are operative options and therefore carry the risks of a surgical procedure. We present a case of a conservatively managed proximal phalanx fracture using a reversed dynamic or static finger extension splint, such as Roylan...

Giant cell tumour (GCT) of bone arising from a phalanx of a finger is extremely rare. Only two percent of all reported GCTs are found in the hand, which show a higher rate of recurrence as compared to those occurring at a more proximal location. Here we report a rare case of giant cell tumour of proximal phalanx of the ring finger in a 20-year-old male, which was treated with extended curettage...

Closed avulsion of the flexor digitorum profundus (FDP) tendon is classified based on the impact of injury on the management plan. In this report, we present a case with unclassified pattern of FDP tendon avulsion. The injury involves an intra-articular fracture of the volar part of distal phalanx of the little finger resulting into two bony fragments, one attached to the retracted avulsed tend...
