The emerging 4G wireless telecommunication technology poses two inevitable constraints for the chipset design: a high level of integration and algorithm complexity. But even though nanomet-ric CMOS technologies make it possible to integrate the required hardware resources into a single chip, enormous difficulties arise for the on-chip interconnections and(More)
The correction of functional deficits of the hand after a brachial plexus lesion is difficult; treatment should be provided by a well-knit team of surgeons and therapists. The patient should be fully aware of the limitations of surgical treatment before surgery, and should be entrusted to the care of a physical therapist during the critical period of nerve(More)
Seven major reconstructions of the femoral shaft using a vascularized graft of bone from the fibula were performed at the Massachusetts General Hospital from 1981 to 1984. Three patients had a post-traumatic infected non-union; one, extensive osteomyelitis of the femoral shaft; one, a fractured allograft; one, an atrophic non-union associated with radiation(More)
The surgical treatment of "swan-neck" deformities secondary to mallet finger using Littler's technique (Spiral Oblique Retinacular Ligament) in a series of 35 cases, led to a complete correction of the PIP joint hyperextension in 95% of the cases and a correction of the DIP joint flexure in 70% of the cases. This active tenodesis restores the physiology of(More)
Since 1982 seven patients with volar intercalary segment instability (VISI) have been operated on at the Massachusetts General Hospital. All had preoperative wrist pain and described a painful "clunk" with ulnar deviation. In each case there was palpable evidence of instability when the wrist was deviated ulnarly that produced a "buckling" sensation as the(More)
We present a review of 36 patients with final radiocarpal arthrodesis done between 1976 and 1987. The series was homogeneous: patients were about 40 years old and lesions were work-related. The most frequent reason for the arthrodesis was fracture of scaphoid bone, followed by Kienbock's disease complex trauma of carpus, severe carpal sprain, and articular(More)
Axonal regeneration across 64 median nerve grafts in 34 rabbits was studied histologically to determine the optimal conditions for nerve allografting. Axonal regeneration across allografts in cyclosporin A-treated animals was satisfactory, but it occurred more slowly and with more inflammation and fibrosis than in autografts. Without immunosuppression,(More)
Twenty anatomical specimens were carefully studied in order to establish a possible connection between the posterior interosseous nerve and the radial tunnel syndrome. Our results show that the posterior interosseous nerve distal to the supinator muscle may be compressed by various structures. These include the distal border of the supinator muscle, the(More)
We report a case of involvement of a finger flexor tendon by sarcoidosis. A review of twelve cases suggests that this is a rare manifestation of the illness that most often affects the finger extensors at the wrist. It tends to present in established sarcoidosis and is associated with a higher than usual incidence of polyarthritis. The main differential(More)
Sixteen scapho-trapezio-trapezoid arthrodeses were performed for Kienböck's disease. In ten cases, a prosthetic replacement of the lunate was inserted at the same time. Clinical results were good with regard to pain and fair with regard to grip strength which was improved by an average of 32%. In contrast, the arc of flexion-extension was 38% less than on(More)
