摘要
目的:为肩胛骨骨折的手术内固定提供解剖学依据。方法:对30侧成人肩胛骨标本进行测量,分别用千分尺及螺旋测微仪测量长度和厚度,用角度仪测量角度。所得数据进行统计学处理。结果:肩胛骨的平均长度为(146.3±12.0)mm,离边缘1cm处内侧缘厚度为(4.1±2.5)mm。肩胛骨外侧缘距关节面1cm、2 cm处的前后厚度分别为(17.8±3.5)mm(13.4±3.1)mm,距关节面1/4、2/4、3/4距离处的厚度分别为(13.5±5.8)mm、(11.5±4.0)mm、(8.6±5.0)mm。肩盂关节面有一向后的倾角平均为(5.6±3.1)°。结论:①肩胛骨的内侧缘和外侧缘有足够的骨量支持内固定物的植入,尤以肩胛骨的外侧缘骨量丰富,是放置内固定物的重要部位;②肩胛颈部较大的骨量及关节面的倾角对于内固定植入和置钉位置有重要意义。
Objective: To provide information for hardware fixation and drill hole placement in the treatment of scapula fractures. Methods: 30 pieces of adult scapula specimen were studied. Linear measurements were made ,while a micrometer measurements of thickness were obtained by a depth gauge. Angular measurements were made by using a goniometer to measure the nearest degree. The overall average, Standard deviation, and range were determined for each of the measurements. Results: The average length of the scapular was 146.3±12.0 mm, the thickness of the medial border at 1 cm from the edge was 4.1±2.5 mm. Anteroposterior thickness of the neck of the scapula at 1 cm and 2 cm from the glenoid was 17.8±3.5mm and 13.4±3.1 mm respectively. The thickness of the lateral border at the point of 1/4,2/4,3/4 length of the lateral border from the surface was 13.5±5.8 mm,11.5±4.5 mm,8.6±5.0 mm respectively. The glenoid faced slightly posteriorly with a tilt angle of 5.6°±3.1°. Conclusions: The medial and lateral borders of the body have sufficient bone mass approximately lcm from the edge to support internai fixation, especially the lateral border which is the most important place for fixation. The glenoid tilt angle and the amount of bone in the neck of the scapula, are particular important in hardware fixation and drill hole placement
