Aneurysmal bone cyst: A 19-case series managed by percutaneous sclerotherapy.

INTRODUCTION: Sclerotherapy offers an alternative to surgery for the treatment of aneurysmal bone cyst (ABC). The main objective of the present study was to assess the radiological efficacy of sclerotherapy in terms of ossification on MRI. Secondary objectives were to assess clinical efficacy on pain evaluation and to analyze recurrence and complications according to type of sclerosing agent and intraoperative imaging technique. MATERIALS AND METHODS: Between 2006 and 2014, 19 patients (7 females, 12 males, aged 3 to 17 years) with ABC treated by sclerotherapy were included. Six received Ethibloc(®), 9 Aetoxisclerol(®), 2 liquid absolute alcohol, and 2 absolute alcohol gel. Assessment used fluoroscopy in 17 cases and CT in 2. Ossification was assessed on MRI and pain on a visual analog scale and HEDEN score. RESULTS: Ossification was complete in 11 cases (84.6%) and partial in 2 (15.4%). Eighteen patients (94.7%) were pain-free at 3 months. There was no recurrence, at a minimum 2 years' follow-up. One case of skin necrosis was observed, associated with use of liquid absolute alcohol; there was 1 case of arterial reflux of Ethibloc(®) under CT control. DISCUSSION: Sclerotherapy enables minimally invasive treatment of lesions that are deep, difficult of access to surgery and potentially damaging. Use of absolute alcohol gel and fluoroscopic control seems to improve the risk/benefit ratio, limiting complications by vascular extravasation of the sclerosing agent, thanks to real-time visualization of diffusion. Its clinical and radiological efficacy makes sclerotherapy and alternative primary treatment choice in ABC. LEVEL OF EVIDENCE: IV, retrospective study.

Results with all-inside meniscal suture in pediatrics.

INTRODUCTION: Incidence of meniscal lesions is increasing in the pediatric population. Given the harmful impact of meniscectomy, meniscal repair is attempted whenever possible. The present study sought to assess the efficacy of FasT-Fix (Smith and Nephew) all-inside arthroscopic meniscal repair devices in childhood meniscal lesions. The study hypothesis was that functional results would be equivalent to those of other suture techniques. MATERIAL AND METHODS: Nineteen patients were assessed following arthroscopic meniscal repair, at a mean 6 years (range: 3-9 years). Mean age was 14.8 years. There was associated ACL tear in 31% of cases. Functional assessment used Lysholm, subjective IKDC, Tegner activity level and KOOS scores. Anatomic assessment of healing used MRI, arthroscopy or CT-arthrography. RESULTS: At last follow-up, the meniscal survival rate was 89.5% (n=17/19). Functional results were good: Lysholm: 95.7/100; subjective IKDC: 90.7/100; Tegner: 7.64. Imaging found systematic healing. DISCUSSION: All-inside arthroscopic meniscal suture is increasingly used in adults, and can also be implemented in children or adolescents in pediatrics. FasT-Fix (Smith and Nephew) implants, although not always easy to use, ensure a perfectly functional knee and conserve long-term meniscal chondroprotection with a low risk of complications. LEVEL OF EVIDENCE: IV, retrospective study.

The authors report a case of malignant chemodectoma of the Xth cranial nerve, presenting with a right cervical swelling in a 68-year-old woman, with cervical lymphatic invasion. It was treated by surgical excision complemented by irradiation.
