Abstract

Joint osteonecrosis, characterized by the death of bone tissue, is a serious sequela of antileukemic treatment in adolescents with acute lymphoblastic leukemia (ALL). This condition can lead to significant pain, restricted mobility, and a reduction in quality of life. Despite its impact, there is a lot of research focused specifically on treatment strategies for adolescents with joint osteonecrosis, making it a considerable clinical challenge.
We examined two cases of adolescents with extensive joint involvement. The first patient is a 17-year-old female presenting with osteonecrosis affecting multiple joints, including the hips, shoulders, knees, and elbows. Her treatment options spanned from conservative management to surgical interventions such as joint arthroplasty, based on the severity and stage of her symptoms. Despite initial conservative efforts, the complexity and extent of her condition necessitated more invasive surgical procedures to achieve effective symptom relief and restore joint function.
The second patient, a 16-year-old male, demonstrated capitellar osteonecrosis in both elbows and talar osteonecrosis with associated loose bodies. For this patient, arthroscopic surgery was employed to address the osteonecrosis and manage the loose bodies across all affected joints. The surgical approach was chosen due to the limited efficacy of conservative management in alleviating symptoms and improving joint function.
The outcomes of these interventions highlight the limitations of conservative treatments alone in severe cases of joint osteonecrosis. Both patients ultimately required surgical interventions, such as core decompression or joint replacement, to effectively manage pain and enhance mobility. Post-surgical assessments revealed significant improvements in joint function and mobility, with increases in scores across all relevant assessment tools, indicating successful surgical outcomes.
These cases underscore the need for a multidisciplinary approach to managing joint osteonecrosis in adolescents. Effective management often requires a combination of conservative therapies, surgical interventions, and medication. The observed success following surgical treatment in these cases suggests that timely and appropriate surgical intervention can significantly improve patient outcomes.
However, the complexity of joint osteonecrosis in this population highlights the need for further research. A deeper understanding of the underlying mechanisms contributing to osteonecrosis and the development of more targeted treatment strategies are essential. Continued research will be crucial in refining treatment approaches and improving outcomes for adolescents affected by this challenging condition.
