![]() Thus, surgical fixation is considered for the treatment of Neer type IIb distal clavicle fractures. It is reported that unstable distal clavicle fractures have high nonunion rates when treated nonoperatively ( 4, 5). According to the Neer classification system, type IIb is an unstable fracture characterized by the obvious displacement of the fracture and additional rupture of the conoid ligament, leaving the trapezoid intact ( 1, 3). The Neer classification system offers a useful framework for clinicians to assess the type of fractures. The management of distal clavicle fractures still represents a great clinical challenge ( 1, 2). The visual analog scale score and Constant–Murley score in the LPSB group were better than those in the other groups at 3 and 6 months postoperatively ( p < 0.05).Ĭonclusion: Compared with HP and LP alone, LPSB yields better clinical outcomes and lower complication rates in the treatment of Neer type IIb distal clavicle fractures.ĭistal clavicle fractures refer to fractures that occur in the lateral third of the clavicle, which make up approximately 10%–30% of all clavicle fractures. Postoperative complications were lower in the LPSB group than in the other two groups ( p < 0.05). The union time was shorter in the LPSB group than in the other two groups ( p < 0.05). No significant differences were observed, including age, sex, side, time to surgery, duration of surgery, and mean follow-up period among the three groups ( p > 0.05). All patients in the LPSB group achieved bone healing at the final follow-up. Results: The follow-up period was at least 2 years for all patients. ![]() The clinical and radiological outcomes were evaluated, including union time, postoperative complications, and function of the shoulder joint. Methods: We performed a retrospective cohort study of 53 patients with Neer type IIb distal clavicle fractures who were treated with a hook plate (HP group, 16 patients), a locking plate alone (LP group, 18 patients), or a locking plate with a suture button (LPSB group, 19 patients) in our hospital between March 2014 and August 2019. The aim of this study was to compare the outcomes among three different fixation techniques for the treatment of Neer type IIb distal clavicle fractures. However, to our knowledge, there is limited information on clinical outcomes surrounding locking plates combined with a suture button in the treatment of Neer type IIb distal clavicle fractures. Department of Orthopedics, Shanghai Tenth People's Hospital, School of Medicine, Tongji University, Shanghai, Chinaīackground: Recently, a locking plate (LP) combined with a suture button was applied for distal clavicle Neer type IIb fractures.Zhi-Qing Liu † Ming-Shi Zhang † Zi-Fei Zhou Lei Zhang* Long-Po Zheng*
