The combined qudriple lesion : fracture of acromion, distal end of clavicle, distal coracoid and glenoid rim associated with anterior shoulder dislocation: A Case Report: Ryup Sub Kim, Suk Myun Ko, Kyu jung Cho, Hyeok Chae Jeong, Dong Hun Choi; J Korean Soc Fract 2000;13(3):550-554.

Abstract PDF: A distal clavicle fracture, as a single fracture, has been reported frequently in the literature. However, combined anterior shoulder dislocations with fracture of the coracoid or acromion is very rare. Fracture of the coracoid or the acromion are even uncommon, represent 3-5% and 9-12% of scapular fractures respectively, which account for 1 perecnt of all fractures. Combined anterior shoulder dislocations with distal end clavicle or glenoid rim fractures are also rare. We observed the concurrent quadruple lesion: fracture of acromion, distal end of clavicle, distal coracoid and glenoid rim associated with anterior shoulder dislocation. To our knowledge, this combined injury has not been reported previously in the literature. Therefore, We presented the proposed mechanism of injury, course of treatment, and its clinical outcome with brief review of literature.

Clinical Experiences of the Femoral Unicondylar Fractures: Ryuh Sup Kim, Suk Myun Ko, Kyu Jung Cho, Dong Hun Choi, Hyun Woo Park; J Korean Soc Fract 2000;13(3):479-487. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.479

Abstract PDF: PURPOSE
The femoral unicondylar fractures occur less frequently than the supracondylar or intercondylar femoral fractures. We document the problems and results in the treatment of these fractures.
MATERIALS AND METHODS
Eleven patients with minimal follow-up peroid of 12 months were included. In the methods of treatment, the operation with by closed or open reduction and internal fixation with screws was used for 7 cases, the conservative treatment for 4 cases. The therapeutic outcomes were rated by the Lysholm knee scoring scale.
RESULTS
The concomitant injuries including neurovascular, collateral or cruciate ligaments and capsular structures of knee to ipsilateral extremity were frequent events. The therapeutic outcomes were significantly affected by associated injuries. The only 5 cases had satisfactory result by the Lysholm knee scoring scale.
CONCLUSION
These injuries have been considered to be the result of high-energy trauma on flexed knee. The open reduction and internal screw fixation of the femoral unicondylar fractures are necessary for good results because those are unstable and easily displaced. The associated disruption of the cruciate ligament was frequently associated injury and, significantly affected to the therapeutic outcome.

Management of Displaced-Extension Type Supracondylar Fractures of Humerus in Children: Suk Myun Ko, Myung Ku Kim, Kyoung Ho Moon, Ryuh Sup Kim, Kyu Jung Cho, Dong Hun Choi; J Korean Soc Fract 1999;12(2):351-360. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.351

Abstract PDF: From June 1996 to February 1998, we reviewed the cases of 27 patients who had a displaced - extension type supracondylar fracture of the humerus retrospectively. The mean length of follow-up was 1.3 years. According to Gartland classification, type II was 7 cases (26%), type III-A was 11 cases (41%), type III-B was 9 cases (33%). We treated with three different methods, including closed reduction and percutaneous Kirschner-wire fixation, skeletal traction, and cast application after closed reduction. In type II fractures, we used two parallel lateral pins. In type III fractures, we used 2 lateral parallel pins followed by 1 medial crossed pin predominantly. The results of treatment were assessed using the criteria of Flynn et al. We graded cosmetic and functional factors separately. Satisfactory results were achieved by percutaneous K-wire fixation(96%). There were seven neural lesions. These were the result of injury and not of the treatment, with exception of one case. Neural injuries spontaneously resolved at a mean of 2.5 months(range 1.5 to 5 months) after injury. Varus deformity was present in one patient. There was no Volkman's ischemic contracture. Percutaneous Kirschnerwire fixation is advocated as the method of choice for the majority of displaced-extension type supracondylar humerus fractures in children.
