Event Description
This report is being filed after the review of the following journal article: mucciolia c. , et al (2020) rotator cuff integrity and shoulder function after intra-medullary humerus nailing, orthopaedics & traumatology: surgery & research, volume 106, pages 17¿23 (france). This retrospective study aims to assess rotator cuff integrity and shoulder function after 3rd-generation imn in humeral fracture. Between november 2016 and july 2017, a total of 40 out of 50 eligible patients (26 females and 14 males) mean age at trauma, 60 years (range, 20-89 years) with displaced proximal humeral or humeral shaft fractures treated by 3rd generation imn were included in the study. Two types of 3rd generation im nail were used: multiloctm (depuy-synthes, (b)(6) usa), and aequalistm (wright-tornier, bloomington, mn, usa). 34 patients were treated with aequalis (tornier¿wright) and 6 with multiloc (depuy¿synthes). Patients were followed in clinics at 6 months for clinical, radiological and ultrasound examination. The following complications were reported: -two shaft fractures were unhealed at 6 months, 1 of which underwent revision at 10 months for decortication, bone graft and screwed plate fixation. -one case of painful lhb, tendinopathy was treated by arthroscopic tenotomy without nail removal. -2 cases of shaft non-union. -1 case of ascended greater tuberosity malunion. -6 cases of persistent varus: 3 due to insufficient reduction (99 degrees varus preoperatively and 112 degrees postoperatively). -6 cases of persistent varus: and 3 due to secondary displacement with medial comminution and excessively lateral nail entry. -nail entry portal was being lateral (tuberosity-cartilage junction) in 19 cases. -nail entry portal was being too lateral (tuberosity) in 6. -nail height was low in 5 cases. -results ultrasound found 5 supraspinatus tendon tears: 2 full and 3 deep partial tears. In 2 of the 3 deep partial tears, the nail was protruding and lateral (tuberosity-cartilage junction). -nail height was protruding in 3 cases. -one excessively long lateromedial proximal screw in a multiloc nail, causing impingement with the glenoid, was removed. -eight patients (7 with proximal humerus fracture) showed lhb tenosynovitis, defined as abnormal quantity of liquid in the groove on ultrasound. Ct demonstrated technical issues in 4 of the 8 patients: 3 cases of lhb tenodesis by anterior screw and 1 of lhb impingement by an excessively long posterior screw. -there were 5 deaths. This report is for an unknown synthes multiloctm intramedullary nail. This is report 4 of 6 for (b)(4).
