Kienböck’s disease is a rare disease described as progressive avascular osteonecrosis of the lunate. The typical manifestations include a unilateral reduction in wrist motion with accompanying pain and swelling. Besides recent advances in treatment options, the etiology and pathophysiology of the disease remain poorly understood. Common risk factors include anatomical features including ulnar variance, differences in blood supply, increased intraosseous pressure along with direct trauma, and environmental influence. The staging of Kienböck’s disease depends mainly on radiographic characteristics assessed according to the modified Lichtman scale. The selection of treatment options is often challenging, as radiographic features may not correspond directly to initial clinical symptoms and differ among age groups. At the earliest stages of Kienböck disease, the nonoperative, unloading management is generally preferred. Patients with negative ulnar variance are usually treated with radial shortening osteotomy. For patients with positive or neutral ulnar variance, a capitate shortening osteotomy is a recommended option. One of the most recent surgical techniques used in Stage III Kienböck cases is vascularized bone grafting. One of the most promising procedures is a vascularized, pedicled, scaphoid graft combined with partial radioscaphoid arthrodesis. This technique provides excellent pain management and prevents carpal collapse. In stage IV, salvage procedures including total wrist fusion or total wrist arthroplasty are often required.
Osteoid osteoma (OO) is a common benign bone tumour, usually affecting young people. Typically, it is localised to the diaphyses or metaphyses of long bones. The classical manifestation includes distinctive night pain, almost always present, responding well to non-steroidal anti-inflammatory drugs, sometimes accompanied by complaints due to physical activity, and a typical picture on additional tests. A characteristic of osteoid osteoma is the presence of a nidus, usually visible on imaging tests. The nidus generally presents as a single, round lytic lesion up to 1 cm in diameter, surrounded by an area of reactive ossification. However, OO is a multifaceted neoplasm, and its diagnosis can cause numerous difficulties. OO can mimic multiple diseases and vice versa, which often leads to a prolonged diagnostic and therapeutic path and associated complications. There are few literature reviews about the differentiation and diagnostic difficulties of osteoid osteoma. Very effective therapies for this tumour are known, such as ablation and resection. Enhanced detection of osteoid osteoma could result in faster diagnosis and less suffering for the patient, avoidance of complications, and reduced costs of incorrect and prolonged treatment.
Osteoid osteoma (OO) is a benign bony lesion with a characteristic radiologic feature of x-ray focus (nidus). The most common symptom indicating diagnosis is strong nocturnal pain that eases with nonsteroidal anti-inflammatory drugs (NSAID). Computed tomography (CT) is a method of choice for diagnosing and localizing the tumor. Osteoid osteoma can regress spontaneously, thus conservative treatment is one of the methods of choice. In the past open resection surgery had been a standard management of osteoid osteoma until radiofrequency ablation (RFA) was discovered in the early 1990s. Nowadays, there are a few minimally invasive treatment techniques that are used. CT-guided radiofrequency ablation is considered a gold standard technique these days. Many cases occur with late diagnosis, and delayed treatment despite of characteristic symptoms. Therefore, it is crucial to be familiar with the clinical features of osteoid osteoma, proper diagnostic patterns, and treatment schemes.
Osteoid osteoma is a common benign bone tumor. The classic presentation includes nocturnal pain that responds well to nonsteroidal anti-inflammatory drugs. Osteoid osteoma can mimic many conditions, including juvenile idiopathic arthritis, infection, malignant neoplasm, and post-traumatic condition. We present the case of a 14-year-old girl with a months-long history of pain with limited mobility of the left hip joint. The patient was subject to several incorrect diagnoses followed by incorrect treatment pathways. Initially, a post-traumatic condition was diagnosed, then latent tuberculosis and juvenile idiopathic arthritis. Numerous hospitalizations, laboratory and imaging studies, and inappropriate treatment delayed the diagnosis and appropriate management by 2 years. Ultimately, a CT scan of the hip joints enabled the correct diagnosis to be made. Thermal ablation with intraoperative 3D navigation was utilized to successfully treat the lesion.
Introduction. Treatment of benign bone tumors and tumor-like lesions is undertaken by numerous Orthopedic surgeons worldwide. Several treatment modalities exist including curettage and bone grafting. CERAMENT is a novel bioresorbable bone substitute used for grafting. Aim. Assessment of preliminary result of treatment of benign bone tumors and tumors like lesions utilizing CERAMENT as a bone substitute. Analysis of therapeutic and diagnostic path and symptoms reported by patients with tumors and tumor-like lesions. Materials and methods. To the retrospective study 38 patients undergoing curettage and bone substitution with CERAMENT® BONE VOID FILLER were included (26% of them were females). We utilized patients’ history. Each patient had an X-ray in the twelfth month after surgery, which was analyzed using the modified Neer classification. The follow-up was 24 months. Results. The unicameral bone cyst was the most commonly encountered lesion (36.8%). Pain was the most common symptom reported (28.9%). Half of all cases were discovered accidentally on X-rays ordered for a different indication. Nearly a quarter of the cases (23.7%) were complicated by pathologic fracture. The distribution of scores in modified Neer score was as follow: SCORE I- 52.6% SCORE II- 15.8% SCORE III-10.6% SCORE IV-2.6%. Complications of procedure were noted in 18.4% of patients. 10.5% of patients had serious discharge from the operated site, 7.9% of patients had surgical wound infection. One case of recurrence was noted. Conclusions. Bone substitute – CERAMENT is suitable for use in the treatment of benign bone tumors and tumors like lesions. It is easy in application and is well tolerated by the patients. The problem is the relatively high rate of complications, mainly serous leakage from the wound.
