• Swelling: There may be noticeable swelling over the affected area, which can be due to the cyst itself or associated inflammation.
• Limited Range of Motion: Depending on the size and location of the cyst, patients may have restricted movement in the forearm or wrist.
• Fractures: Bone cysts can weaken the bone structure, leading to an increased risk of fractures, which may present as acute pain and deformity.
• Asymptomatic Cases: Many cysts are discovered incidentally during imaging studies for unrelated issues, and patients may not exhibit any symptoms.

Patient Characteristics

Certain demographic and clinical characteristics are often associated with patients who have bone cysts in the forearm:

• Age: Bone cysts are more common in children and adolescents, particularly simple bone cysts, which typically occur in individuals aged 2 to 25 years[1][2].
• Gender: There is a slight male predominance in the occurrence of bone cysts, particularly in younger populations[3].
• Underlying Conditions: Some patients may have underlying conditions such as osteogenesis imperfecta or other metabolic bone diseases that predispose them to cyst formation[4].
• Activity Level: Active individuals, especially those involved in sports, may be more likely to experience symptoms related to bone cysts due to increased stress on the forearm bones.

Conclusion

ICD-10 code M85.63 encompasses a variety of bone cysts in the forearm, each with distinct clinical presentations and implications for patient management. While many cysts may be asymptomatic and require no treatment, symptomatic cases may necessitate further evaluation and intervention, including imaging studies and possibly surgical options.
