Pitfalls, Errors, and Unintended Consequences in Musculoskeletal Oncology: How They Occur and How They Can Be Avoided

Potter, Temple, et al.·JBJS Rev·2013·6 citations·Review article

|

This critical analysis review catalogs the most consequential errors non-tumor surgeons make when managing bone and soft-tissue tumors — including unplanned excisions, inappropriate biopsy technique, transverse incisions, and inadvertent intramedullary nailing of primary sarcomas — and provides specific principles for avoiding them.

Key Findings

Soft-tissue masses presenting as hematomas are malignant until proven otherwise — of 31 such cases, 27 were sarcomas and 3 were metastases, with a mean diagnostic delay of ~7 months during which patients underwent aspirations, I&D, and unplanned excisions
A well-defined, painless border does NOT indicate benignity — most soft-tissue sarcomas are well-defined, deep to fascia, and >5 cm; an ill-defined border more commonly suggests benign-aggressive lesions like fibromatosis
Unplanned excisions leave residual tumor in most cases and increase local recurrence; subsequent re-excision and radiation cannot restore the local control achieved by initial planned wide resection
Up to 33% of sarcomas are subcutaneous, so superficial location cannot exclude malignancy; excisional biopsy is appropriate only for lesions that are both superficial and <3 cm
Inadvertent IM nailing of a primary bone sarcoma contaminates the entire medullary canal and may mandate total bone resection or disarticulation — in any patient without confirmed metastatic disease, biopsy with frozen section must precede fixation
