Osteochondromas originating from unusual locations complicating orthopedic discipline: case series.
- Bu çalışma, alışılmadık bölgelerde yerleşen osteokondromların omuz mekaniği bozukluğu, idrar yapma güçlüğü ve sinir sıkışması gibi nadir görülen semptomlara yol açabileceğini göstermektedir.
- Özellikle skapula, klavikula ve kaburga gibi yassı kemiklerde görülen bu tümörler, alışılmışın dışındaki klinik tablolar nedeniyle teşhis aşamasında yüksek klinik şüphe gerektirmektedir.
- Semptomatik vakaların çoğunda cerrahi eksizyon yöntemiyle başarılı sonuçlar elde edilirken, fibula başı yerleşimlerinde sinir sıkışması riskine karşı dikkatli olunmalıdır.

Clinical Evaluation of Osteochondromas in Unusual Locations
This report presents the clinical, radiological, and follow-up results of seven patients diagnosed with extraordinary located osteochondromas. The study, conducted at Antalya Memorial Hospital between February 2009 and March 2014, highlights the significance of recognizing rare symptoms associated with unusual anatomical sites. By analyzing these cases, we aim to underscore the diagnostic challenges and treatment outcomes of these atypical presentations.
Patient Classification and Methodology
To ensure a comprehensive analysis, the patients were classified based on specific criteria including localization, symptomatology, and the presence of neurovascular involvement or organ compression. The findings were further compared with existing literature to validate the clinical observations. Out of the seven cases, five patients exhibited unusual symptomatology, necessitating a tailored approach to their management.
Treatment Approaches and Follow-up Results
Regarding the management of these cases, surgical excision was performed on six of the seven patients. One patient was managed through scheduled outpatient visits for observation. The clinical follow-up results were categorized as good to excellent, demonstrating the efficacy of surgical intervention in symptomatic cases of rare osteochondromas.
Detailed Case Analysis: Symptoms and Localizations
The following table summarizes the diverse clinical manifestations observed in our patient group based on the specific location of the osteochondroma:
| Localization | Clinical Symptoms and Findings |
|---|---|
| Clavicle | Impaired shoulder mechanics and painful shoulder |
| Pubic Ramus | Obstructive urination symptoms and dysuria |
| Scapula | Snapping scapula symptoms |
| Fibular Head (Case 1) | Peroneal nerve compression |
| Fibular Head (Case 2) | Tibial nerve compression |
| Ischial Ramus | Sciatica |
| First Rib | Radiological evidence of subclavian artery compression (Asymptomatic) |
Clinical Implications for Flat Bone Involvement
Based on our institutional experience, flat bones—which typically undergo intramembranous ossification during the fetal period—are less commonly affected by osteochondromas. This group includes the scapula, ilium, pubic ramus, ischium ramus, ribs, and clavicle. When these areas are involved, patients often present with unusual symptoms that require high clinical suspicion for accurate diagnosis.
Critical Considerations for Fibular Head Osteochondromas
While osteochondromas originating from the fibular head may initially appear benign to an orthopedic surgeon, they carry specific risks. It is crucial to remain alert for potential tibiofibular synostosis and nerve compression in this patient population. Early identification of these complications is vital for preventing long-term neurological deficits and maintaining joint function.
