The purpose of this study was to evaluate the frequency of oedema and fatty degeneration of the soleus and gastrocnemius muscles in patients with Achilles tendon abnormalities.
Forty-five consecutive patients (mean 51 years; range 14-84 years) with achillodynia were examined with magnetic resonance (MR) images of the calf. The frequency of oedema and fatty degeneration in the soleus and gastrocnemius muscles was determined in patients with normal tendons, tendinopathy and in patients with a partial tear or a complete tear of the Achilles tendon.
Oedema was encountered in 35% (7/20) of the patients with tendinopathy (n = 20; range 13-81 years), and in 47% (9/19) of the patients with partial tears or complete tears (n = 19; 28-78 years). Fatty degeneration was encountered in 10% (2/20) of the patients with tendinopathy, and in 32% (6/19) of the patients with tears. The prevalence of fatty degeneration was significantly more common in patients with a partial or complete tear compared with the patients with a normal Achilles tendon (p = 0.032 and p = 0.021, respectively).
Oedema and fatty degeneration of the soleus and gastrocnemius muscles are common in patients with Achilles tendon abnormalities.
本研究旨在评估跟腱异常患者比目鱼肌和腓肠肌水肿和脂肪变性的发生率。
45 例连续就诊的跟腱痛患者（平均年龄 51 岁；范围 14-84 岁）接受了小腿磁共振（MR）成像检查。在正常肌腱、腱病患者以及部分或完全跟腱撕裂患者中，确定比目鱼肌和腓肠肌水肿和脂肪变性的发生率。
腱病患者中（n=20；年龄 13-81 岁）有 35%（7/20）出现水肿，部分或完全跟腱撕裂患者中（n=19；年龄 28-78 岁）有 47%（9/19）出现水肿。腱病患者中有 10%（2/20）出现脂肪变性，部分或完全跟腱撕裂患者中有 32%（6/19）出现脂肪变性。与正常跟腱患者相比，部分或完全撕裂患者的脂肪变性发生率显著更高（p=0.032 和 p=0.021）。
跟腱异常患者的比目鱼肌和腓肠肌常出现水肿和脂肪变性。
