Fully Navigated Single-Position Prone Lateral Lumbar Interbody Fusion: A Detailed Technical Report and Description of 15 Cases.

Background: Navigation increases the precision and safety of pedicle screw placement and has been used to place interbody cages for lateral lumbar interbody fusion. Single-position surgery shortens its duration and that of anesthesia. The aim of this study was the feasibility of simultaneous cage and screw placement in a single prone position using intraoperative navigation without the need for additional fluoroscopy and a detailed technical description of this procedure.

Multidisciplinary and Coordinated Management of Osteoporotic Vertebral Compression Fractures: Current State of the Art.

Osteoporotic vertebral compression fractures (OVCFs) present a significant health concern, affecting a substantial portion of the older adult population worldwide. This narrative review explores the prevalence, diagnostic challenges and management strategies for OVCFs. Despite the increasing incidence and impact on morbidity and mortality, existing clinical guidelines lack consistency and clear diagnostic and therapeutic recommendations.

Radiographic signs and hip pain 5 years after THA with a cemented stem predict future revision for aseptic loosening: a prospective cohort study.

Background And Purpose: We aimed to evaluate the long-term predictive value of radiographic abnormality and/or hip pain assessed 5 years following primary total hip arthroplasty (THA) and the occurrence of revision for aseptic loosening between 5 and 25 years postoperatively.

Patients And Methods: We included all primary THAs performed between 1996 and 2011 (same uncemented cup, polyethylene-ceramic bearing, 28 mm head, cemented stem) and prospectively enrolled in the institutional registry, for whom baseline and follow-up radiographs were available. At 5 years radiographically we assessed femoral osteolysis and/or stem migration.

Clinical outcomes of 3T magnetic resonance imaging-guided lumbar and sacral foraminal injections.

Purpose: This article evaluates the feasibility, safety, and efficacy of MRI-guided lumbar or sacral nerve root infiltration for chronic back pain. We compared the outcomes of our MRI-guided infiltrations with data from CT-guided infiltrations reported in the literature and explored the potential advantages of MRI guidance.

Method: Forty-eight MRI-guided nerve root infiltrations were performed using a 3 T MRI machine.

[Endoscopic lumbar surgery].

Spinal endoscopy is the result of an evolution of techniques and technologies in the service of an ever less invasive surgery. It allows the treatment of a large range of pathologies such as disc herniation or spinal stenosis and this range continues to increase. It has already proven its non-inferiority and cost-effectiveness compared to microsurgery despite a difficult learning curve.

The SWING test: A more reliable test than passive clinical tests for assessing sagittal plane hip mobility.

Background: Clinical assessment of sagittal plane hip mobility is usually performed using the Modified Thomas Test (for extension) and the Straight-Leg-Raise (for flexion) with a goniometer. These tests have limited reliability, however. An active swinging leg movement test (the SWING test), assessed using 3D motion analysis, could provide an alternative to these passive clinical tests.

Magnetic resonance imaging-guided lumbar nerve root infiltrations: optimization of an in-house protocol.

Background: For the treatment of radicular pain, nerve root infiltrations can be performed under MRI guidance in select, typically younger, patients where repeated CT exams are not desirable due to associated radiation risk, or potential allergic reactions to iodinated contrast medium.

Methods: Fifteen 3 T MRI-guided nerve root infiltrations were performed in 12 patients with a dedicated surface coil combined with the standard spine coil, using a breathhold PD sequence. The needle artifact on the MR images and the distance between the needle tip and the infiltrated nerve root were measured.

Native septic arthritis is not an immediate surgical emergency.

Unlabelled: Acute native joint septic arthritis is generally considered a surgical emergency, requiring drainage within hours, including during night, weekend or holiday shifts. However, there are few data supporting the need for the disruption caused by this degree of urgency.

Methods: We performed a retrospective review of all adult patients seen in our medical center from 1997-2015 with culture-proven septic arthritis and noted the epidemiology of sequelae, and their possible association with a delay in surgical drainage.

[Surgical management of the spinal metastases].

Seventy per cent of patients with cancer have evidence of metastases and spinal involvement may occur in up to 50 %. Pain is the most frequent symptom and it occurs in 90 % of the patients. It exist three different type of spinal pain : inflammatory, radicular and mechanical pain.

Is there a significant seasonality in the occurrence of osteoarticular infections?

Clinical experience suggests fluctuation in the occurrence of osteoarticular infections. We performed a single-centre study during 2004-2012, dividing each year into the four seasons according to the Gregorian calendar. A total of 455 episodes of osteoarticular infections were retrieved.

Are there clinical variables determining antibiotic prophylaxis-susceptible versus resistant infection in open fractures?

Purpose: In Gustilo grade III open fractures, it remains unknown which demographic or clinical features may be associated with an infection resistant to the administered prophylactic agent, compared to one that is susceptible.

Methods: This was a retrospective case-control study on patients hospitalized from 2004 to 2009.

Results: We identified 310 patients with Gustilo-III open fractures, 36 (12%) of which became infected after a median of ten days.

[Treatment and outcome of fractures around the knee in the older patients].

From the age of 50 the risk of fracture during the remaining years of life is estimated to be 40% in women and 20% men. The management of a fracture in the elderly is complex for several reasons, including decreased bone strength, a frequent association with previous joint replacement surgery or another orthopaedic implant, a high risk for anesthesia, difficulty in following postoperative recommendations, and an increased postoperative mortality. This article offers a review of fractures around the knee: distal femur, proximal tibia, patella and periprosthetic fractures.
