Peroneal tendon pathologies are an important cause of pain in the lateral aspect of the ankle. It has been proposed in the literature that low lying peroneus brevis muscle belly occupies more space in the retromalleolar groove and could cause laxity of the superior retinaculum which would promote tendon dislocation, tenosynovitis or ruptures. The objective of the study is to characterise the population with low lying peroneus brevis muscle belly and determine the association between the low lying peroneus brevis muscle belly found on magnetic resonance imaging and clinical peroneal tendon dislocation.
A case-control study was developed with a sample of 103 patients. The cases were patients with low lying peroneus brevis muscle belly and peroneal dislocation and the controls were patients with normal implantation of the peroneus brevis muscle and peroneal tendon dislocation.
The prevalence of clinical peroneal dislocation in patients with low implantation of the peroneal brevis muscle belly was 7.64%, and the prevalence of clinical peroneal dislocation in patients with normal implantation of the peroneus brevis muscle belly was 8.88%. The OR was 0.85 (CI 0.09-7.44, p=0.88).
Our findings indicate that there is no statistically significant relationship between low lying peroneus brevis muscle belly and clinical dislocation of the peroneal tendons.
腓骨肌腱病变是踝关节外侧疼痛的重要原因。文献提出，低位的腓骨短肌肌腹在踝后沟占据更多空间，可能导致上支持带松弛，进而促使肌腱脱位、腱鞘炎或破裂。本研究的目的是描述低位腓骨短肌肌腹人群的特征，并确定磁共振成像上发现的低位腓骨短肌肌腹与临床腓骨肌腱脱位之间的关联。
开展了一项病例对照研究，样本为103例患者。病例为低位腓骨短肌肌腹且伴有腓骨脱位的患者，对照为腓骨短肌和腓骨肌腱植入正常但伴有腓骨脱位的患者。
腓骨短肌肌腹低位植入患者的临床腓骨脱位患病率为7.64%，腓骨短肌肌腹植入正常患者的临床腓骨脱位患病率为8.88%。比值比为0.85（95%置信区间0.09 - 7.44，p = 0.88）。
我们的研究结果表明，低位腓骨短肌肌腹与腓骨肌腱临床脱位之间无统计学显著关系。
