Both in vitro and in vivo experiments have confirmed that platelet-rich plasma has therapeutic effects on many neuropathies, but its effects on carpal tunnel syndrome remain poorly understood. We aimed to investigate whether single injection of platelet-rich plasma can improve the clinical symptoms of carpal tunnel syndrome. Fourteen patients presenting with median nerve injury who had suffered...

The etiology of carpal tunnel syndrome was studied by comparing the role of genetics, sleep position and sexual intercourse as possible causes of idiopathic carpal tunnel syndrome. The etiologic potential of the three theories was analyzed using a modified version of the Bradford Hill criteria of causation. All three theories scored equally well according to eight of the nine Bradford Hill crit...

OBJECTIVE To assess the separate effects of thumb and finger extension/flexion on median nerve position and cross-sectional area. METHODS Ultrasonography was used to assess median nerve transverse position and cross-sectional area within the carpal tunnel at rest and its movement during volitional flexion of the individual digits of the hand. Both wrists of 165 normal subjects (11 men, 4 wome...

BACKGROUND Bisphosphonates are widely used to prevent osteoporotic fractures. Some severe musculoskeletal reactions have been described with this medication; among them, some cases of carpal tunnel syndrome. Thus, the aim of this study was to explore whether bisphosphonates may be associated with this syndrome. METHODS A cohort study was conducted to compare exposed to unexposed women; the ex...

INTRODUCTION Sarcoidosis is a multisystemic inflammatory disease with myriad clinical manifestations. Neurologic involvement in sarcoidosis is uncommon. Peripheral neuropathic presentations include mononeuropathy, mononeuritis multiplex, and generalized sensory, motor, autonomic, and sensorimotor polyneuropathies. CASE PRESENTATION We report a case of carpal tunnel syndrome caused by sarcoido...

Carpal tunnel syndrome is one of the most costly upper extremity disorders in the working population. Past literature has shown an association between personal and work factors to a case definition of carpal tunnel syndrome but little is known about the combined effects of these factors with the development of this disorder. Few studies have examined these associations in longitudinal studies. ...

Ulnar tunnel syndrome could be broadly defined as a compressive neuropathy of the ulnar nerve at the level of the wrist. The ulnar tunnel, or Guyon's canal, has a complex and variable anatomy. Various factors may precipitate the onset of ulnar tunnel syndrome. Patient presentation depends on the anatomic zone of ulnar nerve compression: zone I compression, motor and sensory signs and symptoms; ...

OBJECTIVE To probe into quick and effective therapies for carpal tunnel syndrome. METHODS Totally 98 cases of carpal tunnel syndrome were randomly divided into a treatment group and a control group. The treatment group received warm-needling plus Tuina relaxing, while the control group was treated by hormone block therapy and drug medication. RESULTS The cure rate was 81.7% in the treatment...

We report the development of the carpal tunnel syndrome in 3 hypertensive men (aged 46-58) treated with beta-blockers (propranolol in two patients and metoprolol in the 3rd) for 8-11 years. Known causes of carpal tunnel syndrome were excluded in each case. Withdrawal of the beta-blocker was followed by complete resolution of symptoms and signs after a period of 8-10 weeks. No evidence of recurr...

Stonefish envenomation is a common marine sting. Although stonefish injuries are commonly sustained during maritime activities, this local delicacy can also be considered a regional occupational hazard for chefs. The availability and consumption of stonefish in local restaurants has increased the risk of acute carpal tunnel syndrome after a stonefish injury. This case report describes acute car...
