Osteocartilaginous

A developmental dysplasia of peripheral growth plate which forms a cartilage capped projection of bone found near metaphyses of long bones peripheral chondroblast grows outward from the metaphysis, acting as an ectopic growth plate, which ceases growth at skeletal maturation hence, there is an excrescene of trabecular bone capped by a thin zone of proliferating cartilage; it is the most common benign bone tumorusually occurs in long bones, but may occur any bone that is preformed in cartilage

Clinical Presentation

look for a firm, nontender, immovable mass arising near end of the long bone

A symptomatic lesion, may be caused by irritation of overlying soft tissues which may go on to form a fluid filled bursa bursal fluid may be mistaken for a soft tissue mass

Diagnostic studies

x-ray appearance of an exostosis is either flat, sessile lesion or a peduculated (stalk like) process peduncultaed osteochondromas are oriented in proximal direction x-ray hallmark is blending of tumor into underlying metaphysis look for a well defined metaphyseal excrescence of bone w/ a mottled density

Treatment

no treatment is required if the diagnosis is not in doubt and if the patient is relatively asymptomatic surgical resection is indicated for persistant irritation (from bursitis) or for neurovascular compromise surgical resection is also indicated for continued osteochondroma growth after skeletal maturity definitive treatment includes marginal excision of an active exostosis,  including the cartilaginous cap & overlying perichondrium deep bony base has minimal activity and may be removed piecemeal the cartilaginous cap should not be traumatized during its removal prognosis for a solitary exostosis is excellent

Hip Arthroscopy

evaluation of hip pain- candidates are patients with nonspecific radiographic findings and reproducible, functionally-limiting
