Sciatic nerve pain, affecting 12%-27% of the general population, often arises from a myriad of etiologies due to the complex anatomy of the sciatic region. The intricate relationship between the sciatic nerve and surrounding structures in the pelvis poses significant challenges in both diagnosis and surgical management. We report two cases of adult female patients presenting with chronic sciatic pain, refractory to conservative treatment.

Ankle arthrodesis through minimally-invasive transfibular approach: a new surgical technique.

Eur J Orthop Surg Traumatol

July 2024

Department of Pediatric Orthopedics and Hand Surgery, Specialized Orthopedic University Hospital "Prof. B. Boychev", Nikola Petkov str. 56, Gorna Banya, 1614, Sofia, Bulgaria.

Purpose: The purpose of our work was to demonstrate the surgical technique of ankle arthrodesis using the minimally-invasive transfibular (MITF) approach, which minimizes soft tissue damage and is advantageous for high-risk patients.

Methods: In this prospective study, a total of 12 patients with end-stage varus ankle osteoarthritis, including high-risk individuals, underwent ankle arthrodesis using the MITF approach. The technique involves a unique osteotomy at the joint space level, minimizing soft tissue detachment from the fibula.

The human knee is a complex joint that comprises several ligaments, including the medial collateral ligament (MCL). The MCL provides stability to the knee and helps prevent its excessive inward movement. The MCL also has a thin layer of connective tissue known as the epiligament (EL), which adheres to the ligament.

The aim of this study was to assess the epiligament theory by determining the normal epiligament morphology of the proximal and distal parts of the anterior cruciate ligament in humans and analyzing the differences between them and the midportion of the ligament in terms of cell numbers and expression of CD34 and α-SMA. Samples were obtained from the anterior cruciate ligaments of 12 fresh knee joints. Monoclonal antibodies against CD34 and α-SMA were used for immunohistochemistry.

Background: This study evaluated and compared the expression of VEGF, CD34, and α-SMA in the anterior cruciate ligaments and medial collateral ligaments in healthy human knees in order to enrich the epiligament theory regarding ligament healing after injury.

Methods: Samples from the mid-substance of the anterior cruciate ligament and the medial collateral ligament of 12 fresh knee joints were used. Monoclonal antibodies against CD34, α-SMA, and VEGF were used for immunohistochemical analysis.

Article Synopsis
  • 90% of knee ligament injuries involve either the medial collateral ligament (MCL) or the anterior cruciate ligament (ACL), with the MCL showing better healing compared to the ACL.
  • This article aims to review historical perspectives on the healing of these ligaments, explore theories behind why the ACL fails to heal properly, and introduce a new theory called the "epiligament theory" concerning ligament healing processes.
  • It emphasizes the need for future research into the microstructure of surrounding tissues to improve understanding and treatment of ligament injuries, particularly for the ACL.
