1/9. Hypothenar hammer syndrome: an uncommon and correctable cause of digital ischemia.Hypothenar hammer syndrome (HHS) is the rare entity of finger ischemia secondary to embolic occlusion of the digital arteries as a result of repetitive trauma to the palmar ulnar artery. We report the case of a young man found to have digital embolic complications from an ulnar artery aneurysm. This is thought to have developed as a result of palmar trauma experienced during military rifle drill exercises.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
2/9. Mogul skier's palm: traumatic hypothenar ecchymosis.A unique purpuric--golden lesion on the hypothenar eminence of each palm is described in a mogul skier. These painful lesions, resulting from vigorous repetitive pole planting in the "bumps" at a ski area, are postulated to represent a form of localized soft tissue injury.- - - - - - - - - - ranking = 2.5keywords = palm (Clic here for more details about this article) |
3/9. Chronic finger joint instability reconstructed with bone-ligament-bone graft from the iliac crest.Five patients with chronic instability of digital joints presented with instability and functional disability. Two patients had ulnar collateral ligament damage of the thumb metacarpophalangeal joint and another had chronic multidirectional instability due to radial collateral ligament, dorsal capsule and palmar plate laxity of the metacarpophalangeal joint of the thumb. The fourth patient had a lax radial collateral ligament and palmar plate of the proximal interphalangeal joint of the little finger and the fifth had chronic laxity of the ulnar collateral ligament of the interphalangeal joint of the thumb. All were reconstructed with bone-ligament-bone graft harvested from the iliac crest. The graft was fixed with screws and joint stability was achieved intra-operatively in all patients. All patients achieved a stable joint with improved functional performance at final follow-up.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
4/9. Hypothenar Hammer Syndrome: rare or underdiagnosed?Hypothenar hammer Syndrome (HHS) is a condition characterised by digital ischaemia as a result of repetitive trauma to the hypothenar eminence of the hand. It occurs in people who repeatedly use the palm of the hand as a hammer to push, grind or twist objects. It is a curable and a preventable cause of upper digital ischemia. In this report we present a case of HHS and discuss the causes and pathogenesis of this syndrome. We review the incidence, clinical characteristics, differential diagnosis, investigation and treatment.- - - - - - - - - - ranking = 0.5keywords = palm (Clic here for more details about this article) |
5/9. Distal avulsion of the palmar plate of the interphalangeal joint of the thumb.A 63-year-old woman was unable to actively flex the interphalangeal joint of her right thumb after a hyperextension injury. Surgical exploration revealed an avulsion of the distal insertion of the palmar plate, allowing the bulk of the plate to block the joint during attempted active flexion. Resection of the palmar plate restored active flexion and caused no joint instability. We do not believe this lesion, which resulted in this disability, has been previously described.- - - - - - - - - - ranking = 3keywords = palm (Clic here for more details about this article) |
6/9. rupture of the flexor digitorum profundus tendon in the palm caused by repeated, chronic direct trauma.Nonrheumatoid ruptures of the flexor tendons in the palm are rare. We report a case in which excessive exertion caused rupture of the flexor digitorum profundus tendon to the small finger in the palm at the level of the lumbrical origin. The patient had been practicing Japanese fencing for many years. The hard butt end of a bamboo sword impinged precisely on the region in the palm where the rupture occurred.- - - - - - - - - - ranking = 3.5keywords = palm (Clic here for more details about this article) |
7/9. aneurysm of the superficial palmar arch. A case report.We describe a case of compression of the median nerve by an aneurysm of the superficial palmar arterial arch which presented with symptoms of the carpal tunnel syndrome. The traumatic and occupational nature of true palmar aneurysms are discussed.- - - - - - - - - - ranking = 3keywords = palm (Clic here for more details about this article) |
8/9. True aneurysms of the palmar arch of the hand: a report of two cases.We report on two cases of true aneurysms of the palmar arch, both of which were post-traumatic. One was due to repetitive blunt trauma and the other to a glass cut wound. Both aneurysms were detected clinically as pulsating masses without functional disorders. The presence of elastic fibres and smooth muscle in the aneurysm wall proved it to be a true aneurysm. Both aneurysms were excised and replaced by a vein graft from the foot.- - - - - - - - - - ranking = 2.5keywords = palm (Clic here for more details about this article) |
9/9. Hypothenar hammer syndrome in sports.Repetitive blunt trauma or single severe trauma to the hypothenar region may lead to traumatic thrombosis of the distal ulnar artery (hypothenar hammer syndrome, HHS). In the sports-related literature we found and analysed isolated cases attributed to injuries sustained during sporting activities such as baseball, badminton, handball, football, frisbee, softball, karate, weight-lifting and hockey. Further, we report the case of an amateur golf player with ischaemic symptoms of his left hand, where angiography revealed filling defects in the digital arteries associated with a corkscrew-like configuration of the distal ulnar artery. magnetic resonance imaging (MRI) scan demonstrated, at the level of the hamulus ossis hamati, accessory fibres of m. palmaris brevis forming a sling around the ulnar artery. Treatment by resection of the thrombosed a. ulnaris segment and replacement with an autologous vein graft resulted in complete relief of symptoms. Histological sections revealed partially organized thrombi adherent to the intimal surface with fragmentation of the internal elastic membrane, indicating a traumatic genesis. As the mechanism of injury, we suspected intensive golf playing with the grip style and subsequent motions leading to pressure injury of the hypothenar area and the underlying ulnar artery. Contraction of the anomalous muscle belly may have additionally compressed the artery, slowing down the arterial flow and promoting thrombosis. In most reported cases including our own, it took a relatively long time until the cause of the disease as traumatic was found and accepted. The initial repetitive blunt or single severe trauma initiating the HHS can easily be overlooked or ignored. After intimal damage of a. ulnaris, the beginning of symptoms may be prolonged and mislead one into thinking the cause is a collagen or vasospastic disease.- - - - - - - - - - ranking = 0.5keywords = palm (Clic here for more details about this article) |
