“…A concentric needle electrode of the electromyograph was inserted one hands breadth distal to the tibia1 tuberosity and one fingers breadth off the medial edge of the tibia. T h e electrode was directed obliquely through the soleus and flexor digitorum longus muscles, just posterior to the tibia (Inman, 1974;Delagi et al, 1981).…”

Anomalous tibialis posterior muscle as an etiologic factor of hallux valgus

The role of an anomalous tibialis posterior (TP) tendon in the etiology of hallux valgus (HV) deformity was investigated in four stages: clinical, anatomical, neurological, and operative. In the clinical stage, the patients were instructed to planter flex and invert the foot to contract the TP tendon. Attempts to correct the deformity passively were not possible and resulted in moderate pain in all patients (197 feet). When the foot was in dorsiflexion and everted (TP tendon was relaxed) the deformity was easily corrected without any pain in 196 feet (99.5%). In the second stage (anatomical), 10 cadavers (20 feet) with HV deformity and 10 cadavers (20 feet) without any foot deformity were dissected. An abnormal expansion of TP tendon into the oblique part of adductor hallucis was found consistently in all HV feet. The tendinous expansion was absent in all normal feet studied. Also when traction was applied to TP tendon, an increase in the metatarsophalangeal (MP) angle of the big toe was observed in all HV feet, but not in the control group. In the third group (neurological), faradic stimulation was applied to the TP muscle in 7 patients with HV deformity and 7 without deformity. The MP angle was increased in HV patients, but no change was observed in the control group. In the fourth stage, 11 patients (18 feet) surgically operated for HV deformity by proximal metatarsal osteotomy and excision of the band anchoring TP tendon to the oblique part of adductor hallucis. The results were excellent in 10 patients (17 feet) even after a minimum 2.5 year follow-up. Also, in two patients who were operated by different procedures with poor results, the TP tendon was lengthened by Z-plasty and they were completely pain free.Our data show the dynamic role of anomalous expansions of the TP tendon into the oblique part of adductor hallucis muscle in HV patients. We suggest this expansion be excised in addition to other operative procedures selected for the surgical treatment of HV patients.

“…The support for integrated data collection and display is unique to PROTEUS among execution-driven simulators, although Tango provides some form of general monitoring. The CARE simulator [DSNB87], which simulates LISP code using direct execution and a hardware timer, provides integrated monitoring and graphics. The TESS simulator [Sta85], a commercial discrete-event simulation system, provides very general data collection and display abilities, but is not very useful for multiprocessor simulation.…”

Proteus is a high-performance simulator for MIMD multiprocessors. It is fast, accurate, and exible: it is one to two orders of magnitude faster than comparable simulators, it can reproduce results from real multiprocessors, and it is easily con gured to simulate a wide range of architectures. Proteus provides a modular structure that simpli es customization and independent replacement of parts of architecture. There are typically multiple implementations of each module that provide di erent combinations of accuracy and performance; users pay for accuracy only when and where they need it. Finally, Proteus provides repeatability, nonintrusive monitoring and debugging, and integrated graphical output, which result in a development e n vironment superior to those available on real multiprocessors.

The approach to speed up a Lisp interpreter by implementing it in firmware seems promising. A microcoded Lisp interpreter shows good performance for very simple benchmarks, while it often fails to provide good performance for larger benchmarks and applications unless speedup techniques are devised for it. This was the case for the TAO/ELK system. This oaoer describes various techniaues devised for the TAO/ELK system in order to s&ed up the interpreter of the TAO language implemented on the ELK Lisp machine. The &ch;liques include data type dispatch, variable access, function call and so on. TAO is not only upward compatible with Common Lisp, but also incorporates logic programming, object-oriented programming and FortranK-like programming into Lisp programming.TAO also provides concurrent programming and supports multiple users (up to eight users). The TAO interpreter for those pronramminn paradigms is coded fully in microcodes. -1; spite d rich functionalities.the speed of inferpreted codes of TAO is comoarable to that of comniled codes of commercial Lisp machines. Furthermore. the speeds of the interpreted codes of the same program written in various programming paradigms in TAO does not differ so much. This speed balance is very important for the user.Another outstanding feature of the TAO/ELIS system is its firmware development environments.Micro Assembler and Linker are written in TAO, which enables the user to use the capability of TAO in microcodes. Since debuaainn tools are also written in a mini-Lisp, many new ?ools were developed in parallel to debugging of microcodes. This high level approach to firmware development environments is very important to provide high productivity of development.
