20.500.12556/DiRROS-30731 Ultrasound-guided thread versus ultrasound-guided needle release of the A1 pulley: a cadaveric study a systematic review and meta-analysis Purpose To assess and compare two ultrasound-guided, minimally invasive procedures to release the A1-pulley (needle release and thread release) regarding efcacy and safety in an anatomical specimen model. Materials and methods Twenty-one ultrasound-guided needle releases and 20 ultrasound-guided thread releases were performed on digits of Thiel-embalmed anatomical specimens. A scoring system was developed to assess ultrasound visibility, intervention outcome (incomplete, almost complete, or full transection of the A1 pulley), and injury to adjacent structures (neurovascular structures, tendons, A2 pulley). Statistical analysis was performed to compare the score of the two groups (group 1: needle release,group 2: thread release). A P-value of≤0.05 was considered signifcant. Results Needle release was completely successful in 15 cases (71.5%), almost complete release was achieved in four cases (19%), and incomplete transection occurred in two cases (9.5%). Thread release was completely successful in 17 cases (85%), and almost complete transection was observed in the remaining three cases (15%). In both procedures no neurovascular structures were harmed. Slight injury of fexor tendons occurred in two cases (9.5%) in needle release and in fve cases (25%) in thread release. There were no signifcant statistical diferences between the groups regarding ultrasound visibility, intervention safety and outcome, (P>0.05). Conclusion Ultrasound-guided needle release and ultrasound-guided thread release have similar success of release, both being efective and safe techniques for the release of the A1 pulley ultrasonography fingers decompression ligaments cadavers true false true Angleški jezik Slovenski jezik Neznano 2026-07-01 13:12:14 2026-07-01 13:12:14 2026-07-03 03:46:47 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 30. 8. 2024; str. 1513–1521 Vol. 129 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616-07 1826-6983 10.1007/s11547-024-01875-y 205902339 RAZ_Jengojan_Suren_Armeni_2024.pdf RAZ_Jengojan_Suren_Armeni_2024.pdf 1 C4468168B6DE643319E39AC4F77D58E3 cbfd0e7d500fb72a80cef6151a6b2444a0617e71627c666a730b3f67004a15f8 9780fd80-75d4-11f1-a2b4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46984 https://link.springer.com/article/10.1007/s11547-024-01875-y 1 b8bbac5f-753d-11f1-80d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46908 Univerzitetni klinični center Ljubljana 0 0 0
