Chronic exertional compartment syndrome is a well-described potential cause of leg pain in high-level athletes and soldiers. Surgical treatment of chronic exertional compartment syndrome usually involves fasciotomy, with a reported rate of complications of up to 16%, including failure of complete compartmental release and delayed return to normal daily activity, which can take up to 6 to 12 weeks. The use of a minimally invasive approach under ultrasound guidance seems to improve clinical outcomes in young active patients.

Purpose: To assess the feasibility and technical accuracy of performing pedicular screw placement combined with vertebroplasty in the radiological setting.

Methods: Patients who underwent combined vertebroplasty and pedicle screw insertion under combined computed tomography and fluoroscopic guidance in 4 interventional radiology centers from 2018 to 2023 were retrospectively assessed. Patient demographics, vertebral lesion type, and procedural data were analyzed.

Purpose: To evaluate the effectiveness of percutaneous lumbar discectomy (PLD) under computed tomography (CT) guidance on pain and functional capacities and to estimate the speed of recovery by assessing the time to return to work.

Materials And Methods: Patients treated with PLD were prospectively included between December 2019 and April 2021. Data regarding pain, duration of symptoms, analgesia intakes, time of absence from work, and the Oswestry disability index (ODI) were collected.

Introduction: The Flexor Hallucis Longus (FHL) is a muscle that can be subject to multiple impingements caused by exaggerated plantar flexion in athletes. The most common impingement is due to inflammation of the tendon at the retrotalar pulley. The constraints exerted on the FHL are responsible for a pathology called functional Hallux Limitus.

Purpose: To evaluate the efficacy and safety of embolization of hyperemic synovial tissue for the treatment of persistent pain after total knee arthroplasty (TKA).

Materials And Methods: Twelve patients with persistent pain after TKA were enrolled in this prospective, single-center pilot study. Genicular artery embolization (GAE) was performed using 75-μm spherical particles.

Purpose: To evaluate clinical and radiological outcomes of a series of patients treated with a removable percutaneous interspinous process spacer (IPS) (LobsterProject® Techlamed®) for symptomatic degenerative lumbar spinal stenosis (DLSS).

Methods: All patients treated in two centres with this IPS during 2019 were retrospectively reviewed. Procedures were performed under deep sedation or general anaesthesia by two interventional radiologists.

Isolated pathology of the long head of the biceps is an indication for biceps tenotomy. To date, needle arthroscopy allows a direct diagnosis of shoulder lesion. We aimed to evaluate the technical feasibility of an in-office biceps isolated tenotomy by needle arthroscopy.

Purpose: To evaluate the technical efficacy, safety, and reproducibility of automated percutaneous lumbar discectomy (APLD) under CT and fluoroscopic guidance, for treating radiculopathy caused by lumbar disc herniation in patients impervious to conservative treatment.

Methods: A total of 77 patients with symptomatic lumbar disc herniation were treated with APLD in a prospective multicentric study performed in four centers across three countries. Magnetic resonance imaging and/or computed tomography was used to evaluate the disc herniation before and after the procedure.
