However, in recent years, more studies have mentioned closed reduction and percutaneous pinning (CRPP) of these fractures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this retrospective investigation, the radiographic and clinical results of patients with these fractures that were initially managed with CRPP were newly classified. We classified these fractures into three groups according to the degree and pattern of fracture displacement as identified on four radiographic images. In Type I, the fracture is unstable and displacement is \u22652 mm; In Type II degree I, the fracture is unstable and displacement is &amp;gt;2 mm, with single rotation of fragment; In Type II degree II, the fracture is unstable and displacement is &amp;gt;2 mm, with single rotation of fragment, with rotation of fragment and antero-proximal displacement; In Type III, the fracture is unstable and displacement is &amp;gt;2 mm, with posterior dislocation of elbow joint. We also designed an algorithm for closed reduction of these fractures according to this new classification.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We retrospectively analyzed the radiographic and clinical results of 37 unstable fractures (in 22 boys and 15 girls) that were treated with closed reduction. Twenty-one of 25 (84.0%) type I fractures, which could have been reduced to within 2 mm of residual displacement, were treated with closed reduction and pinning with 2 or 3 Kirschner wires (K wires). Three of 5 (60.0%) type II degree I, 3 of 4 (75.0%) type II degree II, and 3 of 3 (100%) type III fractures were treated with CRPP. In 4 of 25 (16.0%) type I, 2 of 5 (40.0%) type II degree I and 1 of 4 (25.0%) type II degree II fractures, closed reduction failed, so ORIF was implemented. There were no complications, such as nonunion, osteonecrosis of the capitellum, superficial or deep infection, malunion, cubitus varus or valgus, or early physeal arrest.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Although the management of type III fractures may not be more difficult than type II fractures with a rotated fracture fragment, as elbow dislocations are usually easy reducible. This retrospective study showed that type III fractures should not be ignored as a lateral condyle fracture that can be cured with CRPP and that lateral humeral condyle fractures with obvious displacement and rotation can be initially treated with CRPP to achieve satisfactory recovery of the elbow. Kirschner wire (K wire) fixation is recommended to avoid reoperation or anesthesia for hardware removal.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2023.1223615","type":"journal-article","created":{"date-parts":[[2023,8,23]],"date-time":"2023-08-23T15:29:06Z","timestamp":1692804546000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Closed reduction and percutaneous pinning for treatment of unstable lateral condyle fractures of the humerus in children"],"prefix":"10.3389","volume":"11","author":[{"given":"Fei","family":"Qiao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohong","family":"Guan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,8,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"20","DOI":"10.1097\/BPO.0b013e318279c4cd","article-title":"Intra-articular corrective osteotomy of humeral lateral condyle malunions in children: early clinical and radiographic results","volume":"33","author":"Bauer","year":"2013","journal-title":"J Pediatr Orthop"},{"key":"B2","doi-asserted-by":"publisher","first-page":"430","DOI":"10.1302\/0301-620X.57B4.430","article-title":"Observations concerning fractures of the lateral humeral condyle in children","volume":"57","author":"Jackob","year":"1975","journal-title":"J Bone J Surg Br"},{"key":"B3","doi-asserted-by":"publisher","first-page":"304","DOI":"10.1016\/j.otsr.2010.10.007","article-title":"Distal humerus lateral condyle fracture in children: when is the conservative treatment a valid option?","volume":"97","author":"Marcheix","year":"2011","journal-title":"Orthop Traumatol Surg Res"},{"key":"B4","first-page":"602","volume-title":"Lateral condylar and capitellar fractures of distal humerus.
