Implementation of ultrasound-guided carpal tunnel release.

Introduction: Ultra-minimally invasive ultrasound-guided carpal tunnel release is a surgical procedure for treatment of carpal tunnel syndrome that is associated with less surgery-related morbidity and faster recovery than open surgery. The objectives of this study were to describe how the surgical technique may be acquired and to report the results obtained after implementation in a clinical setting.

Methods: The study consisted of two parts: 1) description of the surgical skills needed to perform the procedure, and 2) evaluation of the procedure in the first ten consecutively operated patients after 12-month follow-up using questionnaires and magnetic resonance imaging (MRI).

Ultrasound-Guided A1 Pulley Release Versus Classic Open Surgery for Trigger Digit: A Randomized Clinical Trial.

Objectives: We compared an ultra-minimally invasive ultrasound-guided percutaneous A1 pulley release and a classic open surgery for trigger digit.

Methods: We designed a single-center randomized control trial. All cases had clinical signs of primary grade III trigger digit.

Ultra-minimally Invasive Sonographically-guided Trigger Digit Release: An External Pilot Study.

Objectives: The most common surgical option for releasing the first annular pulley in trigger digit (TD) is classic open surgery followed by blind percutaneous release. However, they have been related to major complications and incomplete releases, respectively. Intrasheath sonographically-guided first annular pulley release has recently been shown to be safe and effective in every digit.

3D surgical printing for preoperative planning of trabecular augments in acetabular fracture sequel.

We describe the methodical and possibilities of 3D surgical printing in preoperative planning for a total hip arthroplasty in acetabular deformity after acetabular fractures, showing a case of a 43-year-old with posttraumatic arthritis after both column fracture of the left acetabulum that was treated non operatively, supporting the do it yourself mode.

Ultrasound-guided supra-acetabular pin placement in pelvic external fixation: description of a surgical technique and results.

Introduction: Pelvic fracture in trauma patients can lead to hemodynamic instability. External fixation is a treatment capable of stabilizing these injuries in the context of damage control surgery. Supra-acetabular pin offers the greater biomechanical stability but requires the use of intraoperative fluoroscopy.

Ultra-Minimally Invasive Ultrasound-Guided Carpal Tunnel Release: A Randomized Clinical Trial.

Objectives: The purpose of this study was to compare the outcomes of 1-mm ultra-minimally invasive ultrasound-guided carpal tunnel release and 2-cm blind mini-open carpal tunnel release.

Methods: We conducted a single-center individual parallel-group controlled-superiority randomized control trial in an ambulatory office-based setting at a third-level referral hospital. Eligible participants had clinical signs of primary carpal tunnel syndrome and positive electrodiagnostic test results and were followed for 12 months.

3D Surgical Printing Cutting Guides for Open-Wedge High Tibial Osteotomy: Do It Yourself.

Opening wedge osteotomy has recently gained popularity, thanks to the recent implementation of locking plates, which have shown equivalent stability with greater reproducibility, accuracy, and longevity than the closing wedge techniques and a lower prosthetic conversion rate. We present a new "do-it-yourself" cutting guides system for tibial opening osteotomy. Using a conventional computed tomography digital image, a positioning guide and wedge spacers were printed in three dimensions (3D) for implementing the osteotomy and obtaining the planned correction.

Methods and Guidelines for Venous Thromboembolism Prevention in Polytrauma Patients with Pelvic and Acetabular Fractures.

Sequential compression devices and chemical prophylaxis are the standard venous thromboembolism (VTE) prevention for trauma patients with acetabular and pelvic fractures. Current chemical pharmacological contemplates the use of heparins or fondaparinux. Other anticoagulants include coumarins and aspirin, however these oral agents can be challenging to administer and may need monitoring.

Cup-cage construct for acute fractures of the acetabulum, re-defining indications.

Acetabular fractures in the elderly are challenging injuries. The use of a trabecular metal acetabular cage was investigated as the treatment option in a series of elderly patients with acetabular fractures. At a 2-year follow up, 6 elderly patients were found to have mimimum pain, increased function, and increased scores using the Merle d'Aubigné and Postel system modified by Charnley.

Tantalum cones in revision total knee arthroplasty. A promising short-term result with 29 cones in 21 patients.

Twenty-nine porous tantalum metaphyseal cones were implanted in 21 patients (14 women and 7 men) during revision TKA. The average age at the time of the procedure was 73.3 years.

Ultra-minimally invasive sonographically guided carpal tunnel release: anatomic study of a new technique.

Objectives: The purposes of this study were to measure a safe zone and a path for ultra-minimally invasive sonographically guided carpal tunnel release with a 1-mm incision in healthy volunteers and then test the procedure in cadavers.

Methods: First, a previously reported sonographic zone was defined as the space between the median nerve and the closest ulnar vascular structure. Axially, the safest theoretical cutting point for carpal tunnel release was set by bisecting this zone.

Stoppa approach, an alternative for total hip arthroplasty in an intra-pelvic cup.

Removal of an acetabular prosthesis that has migrated into the pelvis can be hazardous. We describe the preoperative planning and the surgical procedure for removing a severely displaced acetabular component in one patient and outline our recommendation for the use of Stoppa approach because it has advantages of simple dissection, a low complication rate, and may help in preventing life-threatening problems.

Selective 360° percutaneous extensor carpi radialis brevis tendon release for tennis elbow: an experimental study.

Objectives: The purpose of this study was to define in volunteers and cadavers the positions of structures at risk and the extensor carpi radialis brevis (ECRB) origin limits for sonographically guided percutaneous tendon release in tennis elbow.

Methods: First, in volunteers, we used Doppler sonography to determine the position (danger zone) of the structures at risk (neurovascular bundle and radial collateral ligament) from the most lateral point of the epicondyle (point of entry). Second, in cadavers, we studied the footprint of the ECRB's origin for finally performing sonographically guided tendon release (1- to 2-mm incision) away from the danger zone.

Sonographically guided intrasheath percutaneous release of the first annular pulley for trigger digits, part 2: randomized comparative study of the economic impact of 3 surgical models.

Objectives: Trigger digit surgery can be performed by an open approach using classic open surgery, by a wide-awake approach, or by sonographically guided first annular pulley release in day surgery and office-based ambulatory settings. Our goal was to perform a turnover and economic analysis of 3 surgical models.

Methods: Two studies were conducted.

Sonographically guided intrasheath percutaneous release of the first annular pulley for trigger digits, part 1: clinical efficacy and safety.

Objectives: For trigger digits, intrasheath sonographically guided first annular (A1) pulley release has shown safety and effectiveness in cadavers. This clinical study describes sonographically guided A1 pulley release results in terms of resolution of symptoms, safety, and functional recovery.

Methods: Sonographically guided A1 pulley release (11-MHz probe) was used in 48 digits of 48 patients prospectively followed for 11.

Percutaneous intrasheath ultrasonographically guided first annular pulley release: anatomic study of a new technique.

Objective: The purpose of this study was to define in volunteers a safe area for performing a percutaneous intrasheath first annular (A1) pulley release under ultrasonographic guidance in cadavers for the treatment of trigger fingers.

Methods: First, in 100 fingers of 10 volunteers, we used Doppler ultrasonography to determine the limits of the sectors enclosing structures at risk (arteries and tendons). From the synovial sheath's most volar point, we determined the relative position of the arterial walls and the distance to the flexor tendons.
