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...

Palmar fasciitis and polyarthritis syndrome (PFPA) is an uncommon syndrome that affects predominantly elderly women and characterized by symmetrical polyarthritis followed by flexioncontracture of the hands. It is usually associated with a metastatic malignant neoplasm, and therefore implies a poor prognosis. We report a case of a 54-year old woman presented with palmar fasciitis and polyarthri...

It has been proposed that motor imagery contains an element of sensory experiences (kinesthetic sensations), which is a substitute for the sensory feedback that would normally arise from the overt action. No evidence has been provided about whether kinesthetic sensation is centrally simulated during motor imagery. We psychophysically tested whether motor imagery of palmar flexion or dorsiflexio...

The perceived distance between touches on the limbs is generally bigger for distances oriented across the width of the limb than for distances oriented along the length of the limb. The present study aimed to investigate the coherence of such distortions of tactile size perception across different skin surfaces. We investigated distortions of tactile size perception on the dorsal and palmar sur...

Variations of arterial patterns in the upper limb have represented the most common subject of vascular anatomy. Different types of artery branching pattern of the upper limb are very important for orthopedists in angiographic and microvascular surgical practice. The brachial artery (BA) is the most important vessel in the normal vascular anatomy of the upper limb. The classical pattern of the p...

We report the association of a persistent median artery, a bifid median nerve with a rare very high origin palmar cutaneous branch, presenting bilaterally in the upper limb of a 75-year-old female cadaver. The persistent median nerve with a bifid median nerve has been reported in patients presenting with carpal tunnel syndrome. Reports of this neurovascular anomaly occurring in association with...

Address for Correspondence: Dr.(Mrs) Subhra Mandal, MD (Anatomy), Associate Professor, Medical College Kolkata, West Bengal, India. Mobile no.:+919477458100 E-Mail: [email protected] The functional importance of hand is revealed by its rich vascularity contributed by superficial and deep palmar arches (SPA and DPA).Superficial palmar arch is located superficial to flexor tendons, and deep...

Background and objectives: The object of the present research is a study of the palmar whorls, Several unique features are characteristic for the palmar whorls of Macaca mulatta from the Taihang Mountains in central China. Materials and Methods: By direct observation striking dermatoglyphs were obtained from 65 specimens comprising 22 males and 43 females. Results: The whorls in the interdigita...

Dupuytren's disease, (DD), is a fibroproliferative condition of the palmar fascia in the hand, typically resulting in permanent contracture of one or more fingers. This fibromatosis is similar to scarring and other fibroses in displaying excess collagen secretion and contractile myofibroblast differentiation. In this report we expand on previous data demonstrating that POSTN mRNA, which encodes...

Carpal instability nondissociative (CIND) represents a spectrum of conditions characterized by kinematic dysfunction of the proximal carpal row, often associated with a clinical "clunk." CIND is manifested at the midcarpal and/or radiocarpal joints, and it is distinguished from carpal instability dissociative (CID) by the lack of disruption between bones within the same carpal row. There are fo...
