Restoration of pinch in ulnar nerve lesions may be achieved within three or four weeks by a one-stage operation combining nerve repair and tendon transfer. We have been using this approach for nerve injuries of the upper limb since 1961, to meet the socio-economic needs of patients who would otherwise need splints and long-term physiotherapy. In our experience, the procedure of choice is transfer of E.I.P. to adductor pollicis and E.P.B. to the first dorsal interosseous. The operative technique and its results in 18 patients followed up for 37-515 days are discussed.

Objective: Revision and questioning of orthodox principies regarding the conduction of nerve impulse. Design: Retrospective study with clinicai analysis of results. Site: Hospital das Clinicas (HCFMSP), public university institution with research programs and tertiary attention to health. Group members: Author and a team of residents and trainees. Operation: Direct suture of nervous stumps utilizing auxiliary technical procedures:-joint-flexion, nerve transposition, tendon transplants, bone shortening. Measurement: Clinicai evaluation and objective tests for tactile and stereognostic function recovery (WeberTest). Results: Variable, depending on preoperative conditions: -type of lesion, time elapsed since injury. Conclusions: Neurorrhaphy should be the procedure of choice even for long term lesions, although the expected results may be less favourable. Periodical evaluation from 24 hs. postoperative, checking for early undefined signals of nervous function recovery. Association of specific drugs for chemical biophysics of the nerve.
This study deals with the anatomical and clinical bases of the thumb-index finger grip, emphasizing not only its general importance, but also its ergonomic role. A classification according to the different functions of two muscular groups (extrinsic and intrinsic), with special reference to muscular imbalance due to ulnar nerve lesions is proposed. After some general considerations on the function of the hand practical conclusions are drawn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
