However, pathological fractures (e.g., due to malignancy or infection) may exhibit clinical and radiological features similar to osteoporotic vertebral fractures (OVFs), leading to misdiagnosis. We report four cases of pathological vertebral fractures initially misdiagnosed as OVFs: one case of pyogenic spinal infection, one of tuberculous spondylitis, one of brucellar spondylitis, and one of multiple myeloma. These cases highlight the importance of considering further diagnostic evaluation, including biopsy, when laboratory abnormalities or atypical imaging features are present. Preoperative laboratory investigations, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), albumin/globulin (A/G) ratio, and immunofixation electrophoresis, can provide critical clues for identifying underlying etiologies. Additionally, vertebral bone marrow aspiration biopsy during percutaneous vertebroplasty (PVP) is a simple and effective method to exclude hematological disorders and infection.</p>","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"7259158"},"PeriodicalIF":0.4,"publicationDate":"2026-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13288042/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148319554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Foot polydactyly is traditionally classified into preaxial, postaxial, and central types, with postaxial forms being the most common and central forms the rarest. Heptadactyly, defined as the presence of seven digits in a single limb, represents an exceptionally rare and severe expression within this spectrum, most often described as central duplication. Isolated unilateral heptadactyly of the foot with combined preaxial and postaxial duplication is exceedingly rare, with very few cases reported in the literature.</p><p><strong>Case presentation: </strong>We report the case of a 9-month-old female infant who presented with a congenital deformity of the right foot noted at birth. Clinical examination revealed unilateral heptadactyly with seven well-formed toes involving both preaxial and postaxial duplication, resulting in medial and lateral widening of the forefoot. The contralateral foot, upper limbs, and systemic examination were normal, and there was no family history of congenital anomalies. Radiographic evaluation confirmed complete duplication of the medial and lateral rays without central ray involvement, tarsal abnormalities, or syndactyly, consistent with isolated mixed-pattern preaxial-postaxial heptadactyly. Given concerns regarding footwear and future gait function, elective surgical correction was performed at 9 months of age. The procedure involved excision of the most medial and lateral supernumerary rays with meticulous preservation of neurovascular structures and reconstruction of soft tissues to restore a narrowed, stable, plantigrade foot.
