摘　　要：目的:分析近端指间关节(PIP)周围胶原沉积症(PDD)的超声征象。方法:32例PDD患者(PDD组)行PIP超声检查,测量肿胀软组织厚度,并记录其内血流分布情况和肿胀关节数目,观察PIP关节腔积液、滑膜增生、增生滑膜内血流、关节软骨及骨质有无破坏。选择70例健康者为对照组,比对2组间参数差异。结果:①肿胀关节共157个,其中PIP248个,PIP360个,PIP443个,PIP56个。②PDD组、对照组肿胀关节周围软组织厚度分别为:PIP2(5.35±0.82)、(3.80±0.34)mm;PIP3(5.76±0.79)、(4.33±0.38)mm;PIP4(5.10±0.77)、(3.73±0.31)mm;PIP5(3.75±0.56)、(3.37±0.29)mm;2组差异均有统计学意义(均P<0.05)。③PDD组肿胀PIP周围软组织尺、桡侧厚度分别为:PIP2(5.36±0.82)、(5.33±0.82)mm;PIP3(5.78±0.79)、(5.75±0.81)mm;PIP4(5.11±0.75)、(5.10±0.79)mm;PIP5(3.72±0.58)、(3.78±0.56)mm;尺、桡侧差异均无统计学意义(均P>0.05)。④PDD组增厚软组织内均未见明显血流信号。结论:PDD多见于PIP3,其次为PIP2、PIP4;受累关节周围软组织对称性增厚且内无明显血流信号是其主要超声征象。Objective:To analyze the ultrasonic features of pachydermodactyly(PDD).Methods:Thirty-two PDD patients performed ultrasound of the proximal interphalangeal(PIP)joints of each patient’s bilateral hands.The numbers of swollen joints,the thickness of swollen soft tissue and the distribution of blood flow in PIP were recorded.The joint effusion,synovial hyperplasia,blood flow in hyperplastic synovium and the destruction of articular cartilage and bone of PIP were observed.Seventy healthy people were taken as the control group,and the differences of parameters between the two groups were compared.Results:①There were 157 swollen PIP joints,including forty-eight PIP2,sixty PIP3,forty-three PIP4 and six PIP5.②The thickness of soft tissue around the swelling PIP joint and that of normal control group were as follows:PIP2(5.35±0.82)mm,(3.80±0.34)mm;PIP3(5.76±0.79)mm,(4.33±0.38)mm;PIP4(5.10±0.77)mm,(3.73±0.31)mm;PIP5(3.75±0.56)mm,(3.37±0.29)mm,and the differences between the two groups were statistically significant(P<0.05).③The thickness of the ulnar and radial sides of the thickened soft tissue were as follows:PIP2(5.36±0.82)mm,(5.33±0.82)mm;PIP3(5.78±0.79)mm,(5.75±0.81)mm;PIP4(5.11±0.75)mm,(5.10±0.79)mm;PIP5(3.72±0.58)mm,(3.78±0.56)mm,and there were no significant differences between the two sides of thickened soft tissue(P>0.05).④There was no obvious blood flow signal in the thickened soft tissue of PDD patients.Conclusions:PDD is more common in PIP3,followed by PIP2 and PIP4.Symmetrical thickening of the soft tissue around the affected joint and no obvious blood flow are the main ultrasonic signs.
