The treatment of clavicle fractures remains controversial. The objective of this study was to investigate the possibility of clavicular intramedullary fixation by nailing through an anatomic study combined with CT scan studies.
For the anatomic study, 20 clavicles of donated bodies to science (10 men, 10 women, 10 right, 10 left) were used. We measured the length of the clavicle, lateral epiphysis diameter, mean diaphysis diameter, medial epiphysis diameter, lateral width, lateral radius of curvature, medial width and medial radius of curvature. Intramedullary cavity diameter (anteroposterior and superoinferior) and calibration were measured by CT scan study on 20 clavicles.
Average length was 152 mm for men and 140 mm for women. The anteroposterior curvature was most pronounced. The medullary canal had a gradually decreasing size from the distal portion to the middle segment, but never disappeared.
Evaluation of morphological data can clarify the specifications of an intramedullary nail: flexibility of the nail to match clavicle curvature and a locking system to ensure primary stability. Intramedullary fixation by nailing in displaced fractures of the middle portion of the clavicle is a minimally invasive surgical technique, with excellent functional and cosmetic results.
锁骨骨折的治疗仍存在争议。本研究的目的是通过解剖学研究结合CT扫描研究，探讨锁骨髓内钉固定的可能性。
解剖学研究使用20具用于科学研究的捐赠尸体的锁骨（男性10例，女性10例，右侧10例，左侧10例）。我们测量了锁骨的长度、外侧骨骺直径、骨干平均直径、内侧骨骺直径、外侧宽度、外侧曲率半径、内侧宽度和内侧曲率半径。通过对20具锁骨进行CT扫描研究，测量髓腔直径（前后径和上下径）并进行校准。
男性平均长度为152毫米，女性为140毫米。前后弯曲最为明显。髓腔从远端到中段尺寸逐渐减小，但从未消失。
形态学数据评估可明确髓内钉的规格：髓内钉的柔韧性以匹配锁骨曲率，以及锁定系统以确保初始稳定性。锁骨中段移位骨折的髓内钉固定是一种微创手术技术，具有优异的功能和美容效果。
