摘  要：

objective: the symptoms and physical findings of intersection syndrome have been well described in the clinical medical literature. however, the magnetic resonance imaging (mri) findings in patients with intersection syndrome of the forearm have only recently been described in a small number of patients. we review our experience with imaging of intersection syndrome, describe previously unreported mri findings, and emphasize modifications to mri protocols for its evaluation. materials and methods: institutional review board approval was obtained for this retrospective review of patients with mri findings consistent with intersection syndrome of the forearm during the period from january 2004 to september 2006. six patients were identified, three males and three females, with an average age of 39.3 years. the mri examinations were reviewed to assess signal abnormalities within and adjacent to the first and second dorsal extensor tendon compartments (detc): tendinosis, peritendinous edema or fluid, muscle edema, subcutaneous edema, and juxtacortical edema. the overall longitudinal extent of signal alterations was measured as well as the distance from lister's tubercle to the crossover of the first and second detc. results: review of the mris showed increased intrasubstance tendon signal suggesting tendinosis in two of the six patients, peritendinous edema or fluid in all six patients, muscle edema in five of the six patients, and subcutaneous edema in three of the six patients. juxtacortical edema was seen in one patient. peritendinous edema or fluid extended distally beyond the radiocarpal joint in three of the six patients. the average distance from lister's tubercle to the crossover of the first and second detc was 3.95 cm, in keeping with recently published data. conclusion: intersection syndrome is an uncommon mri diagnosis. in addition to the previously described mri findings of edema adjacent to the first or second detc, possibly with proximal extension and subcutaneous edema, we have identified additional abnormalities: tendinosis, muscle edema, and juxtacortical edema. in addition, our review shows that first and second detc signal abnormalities in patients with intersection syndrome are not necessarily limited to the site of crossover but can extend distally beyond the radiocarpal joint. as standard wrist protocols may not include the area of intersection between the first and second detc, coverage may need to be extended to the mid-forearm.

摘  要：

injuries to the peroneal tendons are relatively common worldwide but tendon rupture without significant trauma is uncommon. ankle mechanics can be seriously affected by disruption of one or both of the peroneal tendons although complete rupture can also remain asymptomatic. accessory ossicles are sesamoid bones and are common findings in routine radiology of the foot and ankle. although in the vast majority these "os" are normal variants of anatomy, they can lead to painful syndromes and suffer fractures and even undergo degenerative changes in response to overuse and trauma. although similar syndromes have been discussed in the surgical literature, there is a lack of literature describing the use of modern imaging in the accurate diagnosis and its subsequent assistance towards appropriate management of os peroneum friction syndrome complicated by sesamoid fatigue syndrome. this article presents the plain film, sonographic and magnetic resonance imaging findings in a case of os peroneum friction syndrome complicated by a sesamoid fatigue fracture as well as reviewing the pertinent literature.

受伤的腓骨肌腱比较常见，但全世界肌腱断裂没有重大创伤是少见。踝关节，可以严重影响中断一项或两项腓肌腱完全断裂虽然也可以保持无症状。配件小骨的籽骨，并共同结果在常规放射治疗足部和脚踝。虽然在绝大多数这些“全部”是正常的变体解剖，他们可能会导致令人痛苦的症状，并遭受骨折，甚至发生退行性变化的反应过度和创伤。虽然类似的症状已经讨论过的手术文学，没有足够的文学描述了利用现代影像学的准确诊断及以后的援助，适当的管理全部peroneum摩擦综合征复杂籽疲劳综合征。本文介绍的平片，超声及磁共振成像结果的案件全部peroneum摩擦综合征由籽疲劳断裂以及审查相关的文献。
