[Long-term results of the treatment of juvenile bone cysts]
Insights
This study followed 38 children with juvenile bone cysts, finding surgery effective but with a high recurrence rate. A modified surgical approach is proposed for better outcomes in these bone cyst cases.
Area of Science:
- Orthopedic Surgery
- Pediatric Oncology
- Skeletal Dysplasias
Context:
- Juvenile bone cysts present a significant challenge in pediatric orthopedics.
- Diagnosis often occurs secondary to pathological fractures.
- Surgical intervention is the primary treatment modality for symptomatic cysts.
Purpose:
- To evaluate the long-term outcomes of surgical management for juvenile bone cysts.
- To investigate the recurrence rates associated with conventional surgical techniques.
- To propose a modified surgical procedure to improve treatment efficacy and reduce recurrence.
Summary:
- Thirty-eight pediatric patients (5-14 years) with juvenile bone cysts were followed for up to 20 years.
- Most patients underwent surgical cyst excision and bone grafting, with histological confirmation.
- A 19% recurrence rate was observed, prompting the suggestion of a modified subtotal diaphysectomy with osteosynthesis for large cysts.
Impact:
- The findings highlight the limitations of current surgical methods for juvenile bone cysts.
- The proposed modified technique aims to decrease recurrence rates and enhance functional recovery.
- This research contributes to optimizing surgical strategies for pediatric bone cyst management.
Abstract:
38 children between 5 and 14 years of age with juvenile bone cysts were followed up to a maximum of 20 years. In two-thirds of the cases the diagnosis was made on the occasion of a fracture in the cyst region. One child received conservative treatment, 37 children were operated on. The roentgenological diagnosis of all children operated on was confirmed histologically. The operative procedure consisted in milling out the cysts and filling the cavities with autogenous, allogenous or xenogenous spongiosa. Because of the high recurrence rate (10-40% in the literature and 19% from our own experience) we suggest a modified surgical procedure assuring complete recovery. Subtotal diaphysectomy with interposition of a corticospongious splinter and allogenous spongiosa using a stable osteosynthesis in the case of large primary cysts in metadiaphyseal position is discussed.
