This is regardless of whether the approach is radial or ulnar to the flexor carpi radialis (FCR) tendon. It is not yet clear whether and to what extent this dissection leads to a functional loss of pronation or pronation strength. The aim of this study was to investigate the functional recovery of pronation and pronation strength after dissection of the PQ without suturing.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and methods<\/jats:title>\n                <jats:p>\nFrom October 2010 to November 2011, patients aged over 65 with fracture were prospectively enrolled in this study. Fracture stabilisation was performed via the FCR approach without suturing the PQ. Follow-up examinations took place 8\u00a0weeks and 12\u00a0months postoperatively, and pronation and supination strength were analysed by means of an especially developed measuring device.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>\n212 patients were initially screened and 107 were enrolled. The range of motion compared to the healthy opposite side was Ext\/Flex 75\/66% 8\u00a0weeks postoperatively. Pronation was 97% with a pronation strength of 59%. After 1\u00a0year, the scores improved to Ext\/Flex 83\/80%. Pronation recovered to 99% and pronation strength to 78%.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The present study can show a recovery of pronation as well as pronation strength in a large patient population. At the same time, the pronation strength is still significantly lower 1\u00a0year after the operation than on the opposing healthy side. As the pronation strength recovers as the grip strength and is at all times on a par with the supination strength, we believe that we can continue to refrain from re-fixating the pronator quadratus.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00402-023-04847-5","type":"journal-article","created":{"date-parts":[[2023,3,27]],"date-time":"2023-03-27T18:02:47Z","timestamp":1679940167000},"page":"5445-5454","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Does access through the pronator quadratus influence pronation strength in palmar plate fixation of distal radius fractures in elderly patients?"],"prefix":"10.1007","volume":"143","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0584-343X","authenticated-orcid":false,"given":"Steffi S.
