Background: Schwannomas (neurinomas) are among the most frequent peripheral nerve tumors. Nevertheless, these are seldom located in the lower extremities in association with the femoral nerve.
Clinical Presentation: In this case, the occurrence of a schwannoma adjacent to the femoral nerve is described in a patient presenting with nonspecific pain in the thigh accompanied by a palpable mass. Sensory and motor deficits were not present. Further examinations by MRI and biopsy followed by histopathology, revealed the diagnosis of a schwannoma. The tumor was completely excised.
Conclusion: Although schwannomas of the lower extremities are rare, they should be included in the differential diagnosis. Knowing the typical clinical symptoms, radiological signs, and histopathological findings, diagnosis should be straight forward.

Multivariate description of gait changes in a mouse model of peripheral nerve injury and trauma.

Comprehensive Transplant Center, Department of Surgery, Northwestern University Feinberg School of Medicine, Chicago, IL, United States of America.
Objective: Animal models of nerve injury are important for studying nerve injury and repair, particularly for interventions that cannot be studied in humans. However, the vast majority of gait analysis in animals has been limited to univariate analysis even though gait data is highly multi-dimensional. As a result, little is known about how various spatiotemporal components of the gait relate to each other in the context of peripheral nerve injury and trauma.

Controlling pain after major orthopedic surgery may be challenging, and it is related to delayed recovery, the development of chronic pain, and analgesic dependence. It is well known that effective postoperative pain control can reduce hospital stays by ensuring a more rapid rehabilitation,thereby decreasing the overall costs. Despite the development of analgesics, the use of opioids and their derivates remains the cornerstone of treatment for patients with acute moderate-to-severe pain in association with general or regional anesthesia.

Acta Ortop Mex

Unidad de Investigación. Clínica INDISA. Santiago, Chile.
Introduction: therapeutic equivalence has been established in the effectiveness of peripheral nerve blocks in the management of pain in the postoperative period of anterior cruciate ligament reconstruction. However, it is unknown whether this effect is modulated by the anesthesiologist's experience. The objective was to describe the effectiveness of peripheral nerve blocks during the first 24 hours of the postoperative period, considering patient characteristics and the anesthesiologist's experience.

Hip Int
January 2025
Department of Orthopaedic Surgery, Kanazawa Medical University, Kahoku-gun, Ishikawa, Japan.
Purpose: This study introduces a new technique, spherical periacetabular osteotomy (SPO), performed via a para-sartorial intermuscular (PSIM) approach with a bikini incision, aiming to optimise the benefits of SPO, including preservation of muscles and providing cosmetic advantages.
Methods: Overall, 57 joints of 52 patients (mean age 36 ± 17 years) underwent SPO via the PSIM approach. Preoperative osteoarthritis was classified according to Tönnis grade, with 34 and 23 hips categorised as grades 0 and 1, respectively.
Local infiltration anesthesia with high dose ropivacaine and dexmedetomidine in major knee surgery is safe.
Arch Orthop Trauma Surg
January 2025
Medical University of Graz, Graz, Austria.
Background: The role of local infiltration anesthesia (LIA) in knee surgery is significant. LIA can be more potent than a nerve block, but without the downsides. A wide range of agents are used for LIA, including some off-label medications such as dexmedetomidine and ropivacaine.
