The aims of this study are to investigate the inferior peroneal retinaculum (IPR) regarding morphometric parameters, and contents in the inferior peroneal tunnel (IPT).
One hundred and nine embalmed cadaveric legs were dissected in prone position.
The extension band of the IPR was found in 31.19% of cases. The mean of length, width at the origin, width at the middle part, width at the insertion, and thickness of the IPR [mm] were 23.42 ± 3.54 (17.05-33.68), 13.29 ± 2.56 (5.83-20.92), 14.50 ± 2.37 (6.68-21.34), 10.10 ± 2.63 (4.59-19.17) and 0.48 ± 0.16 (0.20-0.87), respectively. The angle of the IPR to the horizontal axis was 38.51 ± 7.07 (11.67-54.00) degrees. The IPT was divided into the upper and lower tunnels. The normal contents were the tendons of peroneus brevis and peroneus longus in the upper and lower tunnels, respectively. However, additional contents were found in the upper tunnel in 2 cases. One was the tendon of peroneus digiti quinti, and peroneus quartus in the other one. Moreover, an unusual accessory peroneal muscle coursed into the lower tunnel and inserted on the peroneal tubercle. Tears of the peroneus brevis tendon were observed in 2 cases.
These morphometric data might be beneficial in surgical repair for IPR injury.
本研究旨在调查腓骨下支持带（IPR）的形态测量参数以及腓骨下管（IPT）的内容物。
对109条防腐处理的尸体下肢进行俯卧位解剖。
在31.19%的病例中发现了IPR的延伸带。IPR的长度、起始部宽度、中部宽度、止点宽度及厚度[mm]的平均值分别为23.42±3.54（17.05 - 33.68）、13.29±2.56（5.83 - 20.92）、14.50±2.37（6.68 - 21.34）、10.10±2.63（4.59 - 19.17）和0.48±0.16（0.20 - 0.87）。IPR与横轴的夹角为38.51±7.07（11.67 - 54.00）度。IPT被分为上、下两管。正常内容物分别为上、下管内的腓骨短肌和腓骨长肌肌腱。然而，在2例上管中发现了额外的内容物。1例为小趾展肌肌腱，另1例为第四腓骨肌肌腱。此外，一条异常的副腓骨肌进入下管并附着于腓骨结节。在2例中观察到腓骨短肌肌腱撕裂。
这些形态测量数据可能有助于IPR损伤的手术修复。
