Influence of psychomotor skills and innervation patterns on results of latissimus dorsi tendon transfer for irreparable rotator cuff tears


Werner, C M L; Ruckstuhl, T; Müller, R; Zanetti, M; Gerber, C (2008). Influence of psychomotor skills and innervation patterns on results of latissimus dorsi tendon transfer for irreparable rotator cuff tears. Journal of Shoulder and Elbow Surgery, 17(1, Sup):22S-28S.

Abstract

This investigation was performed to analyze the influence of innervation and psychomotor skills on the outcome of latissimus dorsi transfer. Patients with the 10 best and 10 worst results after latissimus dorsi transfer for irreparable rotator cuff tears were selected. All patients meeting the inclusion criteria (n = 12) were subject to a psychomotor test battery (Motorische Leistungsserie) and electromyographic innervation assessment. There was no statistical difference between the 2 groups preoperatively in terms of the commonly tested factors known to influence the results of this procedure adversely. There was a significant difference in both the pattern and selectivity of innervation in the group that had better clinical results. The psychomotor findings were negatively correlated with the range of motion and the strength of the operative shoulder. Function of the operative shoulder could also be predicted by psychomotor function of the uninjured contralateral side. Psychomotor skills testing appears to be a new, potential method by which to predict the outcome of latissimus dorsi transfer.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
