In patients with radial club hand (RCH), there is absence of the radius and severe hypoplasia of the thumb, so both wrist stabilization and thumb reconstruction are essential. When wrist stabilization is performed, recurrence of angulation is a problem. When thumb reconstruction is done, preservation of at least one major dorsal vein is important to prevent necrosis of the reconstructed thumb. ...

Thumb has a critical role in the hand function. It is the most important digit for pinching and grasping. Therefore, thumb amputation demands its replantation or reconstruction to restore the hand functions. A case of hand injury which involved multiple digits along with amputation of thumb is reported. The thumb had amputation level just distal to Metacarpophalangeal joint (MPj) along with amp...

Exoskeletons find application in many fields and can be divided into three main categories: 1) haptic interfaces; 2) power amplifiers; 3) rehabilitation and assistance systems. A number of research groups have developed a number of robotic solutions for supporting the motor activities of the upper limb by integrating advanced technologies in terms of actuation, sensors, control and mechanisms. ...

The insect exoskeleton is a multifunctional coat with a continuum of mechanical and structural properties constituting the barrier between electromagnetic waves and the internal body parts. This paper examines the ability of beetle exoskeleton to regulate internal body temperature considering its thermal permeability or isolation to simulated solar irradiance and infrared radiation. Seven Neotr...

This literature review of exoskeleton design provides a brief history of exoskeleton development, discusses current research of exoskeletons with respect to the innate human-machine interface, and the incorporation of exoskeletons for ergonomic intervention, and offers a review of needed future work. Development of assistive exoskeletons began in the 1960’s but older designs lacked design for h...

Many places in the world are too rugged or enclosed for vehicles to access. Even today, material transport to such areas is limited to manual labor and beasts of burden. Modern advancements in wearable robotics may make those methods obsolete. Lower extremity exoskeletons seek to supplement the intelligence and sensory systems of a human with the significant strength and endurance of a pair of ...

A prospective study was undertaken of fifty-one patients who were randomly assigned to treatment with either a long or a short thumb-spica cast for a non-displaced fracture of the carpal scaphoid. The duration of follow-up was at least until union; the average follow-up was twelve months. Twenty-eight fractures were treated with a long thumb-spica cast and twenty-three, with a short thumb-spica...

The aim of this study was to determine whether differences exist between physiotherapists with work-related thumb pain and physiotherapists without thumb pain. Twenty-four physiotherapists with work-related thumb pain (Pain Group) and 20 physiotherapists without thumb or wrist pain (Non-pain Group), who were working at least 20 hours per week in an outpatient musculoskeletal setting, were compa...

A case is presented of arteriovenous malformation of the thumb, requiring thumb amputation and free fap coverage for curative treatment. The thumb was reconstructed by pollicization of the index finger as a secondary operation. The patient remains free of recurrence after 2 years and uses the pollicized thumb for daily activities.

Thumb hypoplasia is a component of radial longitudinal deficiency. The severity can range from slightly smaller thumb to complete absence. They are often categorised using Blauth classification recommend appropriate treatment. Type II characterised by the first web-space narrowing, underdeveloped or absence thenar muscles, extrinsic and metacarpophalangeal joint instability. author reviews 7-ye...
