A 50-year-old man, right-handed farmer, was admitted to the emergency department after undergoing an agriculture accident. Physical examination on admission revealed a left wrist disarticulation with a deformity of the ipsilateral elbow and forearm (A and B). Plain radiography showed a fracture of the ulna shaft as well as dislocation of the radial head. This radiological finding, also called M...

We explored a new method for simple and accurate control of shoulder movement for externally powered shoulder disarticulation prostheses with a two-axis joystick. We tested 10 subjects with intact shoulders and arms to determine the average amount of shoulder motion and force available to control an electronic input device. We then applied this information to two different input strategies to e...

Understanding the processes of postmortem change in biologic systems is important to the forensic sciences. Previous experimental studies of postmortem change in animals under field conditions made use of animal carcasses that had been incidentally exposed to the effects of freezing and thawing or mechanical damage, or both, and were limited to gross observations. The current study was designed...

Abstract We investigated removal of electrocardiogram (ECG) artifacts from the myoelectric prosthesis control signals, taken from the reinnervated pectoralis muscles of a patient with bilateral amputations at shoulder disarticulation level. The performance of various ECG artifact removal methods including high pass filtering, spike clipping, template subtracting, wavelet thresholding and adapti...

A case of Gollop-Wolfgang syndrome is reported in which an alternative treatment to amputation was chosen. The patient had the classical Y-shaped femur and total tibial agenesis. The recommended treatment in absence of extensor apparatus is knee disarticulation but the parents refused amputation. An alternative treatment was proposed to allow the child to walk. Tibialisation of the fibula and f...

Right ventricular dysplasia is a little understood condition and is almost certainly underdiagnosed as an important cause of recurrent ventricular tachycardia and sudden death. This report describes two patients with right ventricular dysplasia. Their clinical presentation reflects the remarkable diversity of the disease while the potentially life-threatening nature of their arrhythmias and the...

Due to recent improvements in prosthetic limb componentry, through-the-knee (knee disarticulation) amputation has gained new interest for rehabilitation-minded amputation surgeons. Recent objective scientific studies from our gait analysis laboratory have described the walking characteristics of peripheral vascular insufficiency through-knee amputees, and have compared their function with simil...

This unusually rare case of giant primary lymphedema of the left upper extremity in a 21-year old woman, who had undergone five surgical procedures (two Charles' procedures and three partial resections) without lasting clinical improvement, demonstrates the difficulty in achieving satisfactory long-term results in patients with grotesquely huge extremities secondary to primary lymphedema. Disar...

David Bailey, who is 14 years old, has a left transverse total forearm deficiency and bilateral longitudinal femur partial deficiencies. The latter fall into Torode and Gillespie's Group I, with marked femoral shortening. A wedge osteotomy was performed for his gross right coxa vara, which was successful, but an intractable fixed flexion deformity of the right knee led eventually to a knee disa...
