To investigate an appropriate depth of needle insertion during trigger point injection into the rhomboid major muscle.
Sixty-two patients who visited our department with shoulder or upper back pain participated in this study. The distance between the skin and the rhomboid major muscle (SM) and the distance between the skin and rib (SB) were measured using ultrasonography. The subjects were divided into 3 groups according to BMI: BMI less than 23 kg/m(2) (underweight or normal group); 23 kg/m(2) or more to less than 25 kg/m(2) (overweight group); and 25 kg/m(2) or more (obese group). The mean±standard deviation (SD) of SM and SB of each group were calculated. A range between mean+1 SD of SM and the mean-1 SD of SB was defined as a safe margin.
The underweight or normal group's SM, SB, and the safe margin were 1.2±0.2, 2.1±0.4, and 1.4 to 1.7 cm, respectively. The overweight group's SM and SB were 1.4±0.2 and 2.4±0.9 cm, respectively. The safe margin could not be calculated for this group. The obese group's SM, SB, and the safe margin were 1.8±0.3, 2.7±0.5, and 2.1 to 2.2 cm, respectively.
This study will help us to set the standard depth of safe needle insertion into the rhomboid major muscle in an effective manner without causing any complications.
探讨在菱形肌触发点注射时合适的进针深度。
62例因肩部或上背部疼痛前来我院就诊的患者参与了本研究。使用超声测量皮肤与菱形肌（SM）之间的距离以及皮肤与肋骨（SB）之间的距离。根据体重指数（BMI）将受试者分为3组：BMI小于23kg/m²（体重过轻或正常组）；23kg/m²及以上至小于25kg/m²（超重组）；25kg/m²及以上（肥胖组）。计算每组SM和SB的平均值±标准差（SD）。将SM平均值 + 1SD与SB平均值 - 1SD之间的范围定义为安全范围。
体重过轻或正常组的SM、SB和安全范围分别为1.2±0.2、2.1±0.4以及1.4至1.7cm。超重组的SM和SB分别为1.4±0.2和2.4±0.9cm。该组无法计算安全范围。肥胖组的SM、SB和安全范围分别为1.8±0.3、2.7±0.5以及2.1至2.2cm。
本研究将有助于我们有效地设定菱形肌安全进针的标准深度，且不会引起任何并发症。
