Successful Management of Multiple Giant Anterior Sacral Meningoceles Through an Anterior Approach in a Patient With Marfan Syndrome: A Case Report and Literature Review.

Meningoceles refer to the protrusion of meninges filled with cerebrospinal fluid (CSF) through a bone defect. There is scarce literature on the management of multiple giant anterior sacral meningoceles (ASMs). We report the case of a patient with Marfan syndrome presenting with gait disturbances and dizziness triggered by posture changes due to multiple giant ASMs. The patient was managed through an anterior approach involving a multidisciplinary team of surgeons. Care was taken to limit the persistence of CSF leak using an omental pedicled flap. This technique has only been mentioned twice in the literature for such cases. A literature review was conducted focusing on the evolution course and surgical strategy of meningoceles.

Biomechanical evaluation of the ST-knot: A new suture for flexor tendon repair.

PURPOSE: Although tendon lacerations are common, there is currently no consensus on choice of suture. Easy and fast sutures that impart enough strength to allow mobilization are needed. This study compared the ex vivo biomechanical strength (force required to create a 2 mm tendon gap) of a novel suture (ST-knot) with that of a conventional suture (double Kessler). MATERIALS AND METHODS: Forty fresh deep flexor tendons from porcine forelimbs were used. Both repaired tendon ends were mounted on standard traction jaws of an axial traction machine at an initial distance of 40 mm for all tendons. A high-definition camera was used to determine the force forming a 2 mm gap. Ten tendons in group 1 (ST-knot) and 10 in group 2 (double Kessler) were prepared with PDS 4.0 (single thread for Kessler, double thread for ST-knot). Tendons in groups 3 (ST-knot) and 4 (double Kessler) were repaired with PDS 1.0 using the same principle. RESULTS: There was no significant difference in the force required to form a 2 mm tendon gap between groups 1 and 2, and this trend was identical when using a stronger thread in groups 3 and 4. The maximum force before rupture, mode of repair failure, stress and stiffness were also comparable, with no significant differences between groups 1 and 2, or between groups 3 and 4. CONCLUSIONS: The ST-knot showed comparable results to the double-Kessler knot, whichever the thread used. Because it involves fewer steps than conventional techniques and is easy to perform, the ST-knot may offer a therapeutic solution, particularly in complex trauma with multiple tendon injury.

Immediate Proximal Row Carpectomy for Severe Perilunate Dislocation Injuries: A Minimum 5-Year Follow-Up.

Background: In patients with perilunate injuries (PLI) with multiple ligamentous and bony injuries involving the proximal carpal row, open reduction and internal fixation (ORIF) can be difficult and lead to poor functional outcomes. Proximal row carpectomy (PRC) is an alternative procedure that has been used for severely comminuted fractures. The aim of our study is to evaluate the long-term functional outcome (minimum 5 years) of patients that underwent an emergency PRC for PLI. Methods: We conducted a retrospective study of patients who underwent PRC at our centre between 2001 and 2016. Only patients with follow-up data of more than 5 years were included in the study. We evaluated range of motion, grip strength, Mayo Modified Wrist Score (MMWS) and Quick Disabilities of Arm, Shoulder and Hand (Quick-DASH). Radiographic analyses were performed to assess the presence of radiocarpal osteoarthritis and the space between the radius and capitate. Results: Thirteen patients were included, with an average follow-up of 78.07 months (6.5 years). The MMWS was 65 points (four excellent and good, four fair and five poor results) and the Quick-DASH score was 30 points. X-ray analysis reported only 15.3% of patients with radiocarpal arthrosis and an average radio-capitate joint space of 1.92 mm. Conclusions: The outcomes of PRC in the management of PLI are comparable to the results reported in literature for conventional ORIF. PRC is a simpler procedure that minimises the need for re-intervention. Level of Evidence: Level IV (Therapeutic).

Targeted Partial Arthroscopic Trapeziectomy and Distraction: Surgical Technique.

Basal joint osteoarthritis is a real public health problem, yet there is no consensus on its treatment. Although total trapeziectomy, as well as arthroplasty, provides long-lasting efficacy, it does not seem to be adapted to a young population with complications that are often very difficult to manage. In the era of minimally invasive surgery, there is a real interest in finding conservative therapeutic alternatives for young subjects that allow them to "pass a painful milestone" and, thus, postpone the least conservative interventions. This article details the surgical technique of an arthroscopic and conservative technique: The Targeted Partial Arthroscopic Trapeziectomy and Distraction based on two goals: targeted resection of painful arthritic lesions and distraction of the joint to restore ligament tension and hopefully regrow fibrocartilage on resected lesions.
