“…8,63 Furthermore, studies have described associations between the presence and size of an os trigonum and FHL tendon pathology. 14,64,65 In this study, there was no association between the presence of posterior talar variants and FHL tendon pathology or tenosynovitis. This discrepancy may be related to previous study design limitations such as small samples, nonblinding, and lack of reliability assessment.…”

“…This discrepancy may be related to previous study design limitations such as small samples, nonblinding, and lack of reliability assessment. 14,64,65 The majority of studies describing FHL pathology in PAIS have reported data in surgical populations. 4,8,20 This high functioning cohort had a relatively low prevalence of FHL tendon pathology and tenosynovitis.…”

“…8 Flexor hallucis longus (FHL) tendon pathology often occurs alongside PAIS 4,12,13 potentially due to its close anatomical relationship to the posterior talus and os trigonum. 14 Flexor hallucis longus tendon-related imaging findings are also considered an indication for surgery. 11 The diagnostic clinical test is the passive plantarflexion test.…”

“…The bony structures responsible for PAIS include the posterior subtalar joint, the posterolateral process of the talus, and the os trigonum. Tokgöz et al 10 investigated the relationship between the pathologies of the flexor hallucis longus tendon, including injury to the FHL tendon, degeneration, and tenosynovitis related to the presence of the os trigonum. The result showed that the extent of the os trigonum can increase the lesions to the FHL tendon.…”

The purpose of this study was to evaluate the attachment areas of the posterior talofibular ligament (PTFL) on the posterolateral tubercle of the talus and the remaining PTFL attachment areas after consequential bony excision. Methods: Thirty fresh cadaveric ankles were dissected to study the proximal and distal attachment of the PTFL and separated the PTFL into anterior and posterior bundles. The description of the PTFL footprint and the anatomic landmarks from the surrounding structures were analyzed during consequential posterolateral bony excision. Results: The average PTFL dimension was 26.11 mm (length), 7.65 mm (width), and 1.82 mm (thickness). The footprint area of the PTFL on the talar site consists of the posterior bundle (76.82%) and the anterior bundle (23.18%). If posterolateral tubercle excision was stayed up to a line of a bottom of the flexor hallucis longus (FHL) groove, at least 89% of the PTFL can be preserved. Conclusion:The posterior bundle of the PTFL is the main bundle on the talar footprint area. To maintain the majority of the attachment of the PTFL, the resection of the posterolateral process could be performed to the bottom of the FHL tendon groove. If resection reaches to the posterior articular cartilage, less than 50% of the PTFL will be preserved. Understanding the footprint of the PTFL plays a key role in posterior ankle impingement surgery. Clinical Relevance: This study provides guidance for resection of the posterolateral tubercle of the talus and a portion of the PTFL attachment for posterior ankle impingement syndrome. Too much resection of the tubercle may cause instability symptoms.

“…Longitudinal flexor hallucis longus (FHL) tendon tears are sometimes complicated by posterior ankle impingement syndrome [ 9 ]. The presence of an os trigonum has an important role in FHL pathologies, such as tenosynovitis with degenerative changes and partial tendon tear [ 10 ]. However, to date, there have been no reports on a longitudinal tear of the FHL tendon that might be caused by friction between posterior ankle osteochondroma and FHL or on endoscopic removal of loose bodies in osteochondromatosis.…”

We report a rare case of osteochondromatosis of the posterior ankle extra-articular space with a longitudinal tear of flexor hallucis longus (FHL). A 77-year-old woman was referred to our hospital with an approximately 4-year history of pain and swelling in the right posterior ankle joint without obvious trauma. The pain had worsened in the previous 2 years. On presentation, she had tenderness at the posteromedial and posterolateral ankle. Imaging revealed several ossified loose bodies in the posterior ankle extra-articular space. We removed the loose bodies, performed tenosynovectomy around the FHL, and released the FHL tendon using a posterior arthroscopic technique via standard posterolateral and posteromedial portals. A longitudinal tear and fibrillation were detected in the FHL. The patient was able to return to her daily activities approximately 3 weeks after surgery. At the 1-year follow-up visit, she continued to have minor discomfort and slight swelling on the posteromedial aspect of the right ankle but had no recurrence of the ossified loose bodies. To our knowledge, this is the first report of osteochondromatosis of the posterior ankle extra-articular space with a longitudinal tear of the FHL that was treated by removal of loose bodies, tenosynovectomy around the FHL, and release of the FHL tendon via posterior ankle arthroscopy.
