Posterior talus osteochondroma a rare location, treated by posterior ankle arthroscopy

Posterior Ankle Arthroscopy for Osteochondromatosis of the Posterior Ankle Extra-Articular Space with a Longitudinal Tear of Flexor Hallucis Longus

“…We treated a 77-year-old woman who presented with osteochondromatosis of the posterior ankle extra-articular space accompanied by a longitudinal tear of the FHL by resection of the loose bodies that might be caused by osteochondromatosis, tenosynovectomy around the FHL, and release of the FHL tendon via posterior ankle arthroscopy. There are a few reports on osteochondromatosis in the posterior extra-articular ankle space treated via a posterior ankle arthroscopic approach [ 2 , 6 , 7 ] but none that include a longitudinal tear of the FHL that might be caused by friction between the loose bodies and the FHL, as this case.…”

“…Open surgery for osteochondromatosis in the posterior ankle space has been reported [ 8 , 13 ]. However, there are few reports on posterior arthroscopic surgery for osteochondromatosis in the posterior ankle space [ 2 , 6 , 7 ]. Arthroscopic approaches have gained popularity in the past decade because they cause less scarring and postoperative pain, are associated with minimal overall morbidity, and allow earlier return to normal activity.…”

“…It is 20–50% of all benign bone tumors and 10–15% of all bone tumors [ 1 ]. Pathogenesis of osteochondroma is still controversial, but some osteochondromas can be replaced by osseous tissue through the process of enchondral ossification, and these chondromas are ossified over a period of time finally [ 2 ]. Osteochondroma is the lesion that is composed of cortical and medullary bone with an overlying hyaline cartilage cap.…”

Talus localized osteochondromas: Treatment management andmid-term outcomes - Case series

“…[1,5,6,19] Malignant degeneration results in a low degree peripheral chondrosarcoma managed with complete surgical resection. [9,14,19,21] It has been reported that the postoperative recurrence rate is 1-2% in osteochondromas. In our study, no recurrence was encountered.…”

“…[5] In general, osteochondroma is first diagnosed at ages six to 20 years with rapid growth, although talus localized osteochondromas have been diagnosed in adults in most cases (61.5%). [1,4,[6][7][8][9][10] In this study, we aimed to define the demographic and clinical findings of patients with talus localized osteochondroma, to present treatment management and mid-term results.…”
