The annular ligament has a crucial role in the radial head stability and  it is critical to the proper functioning of the proximal  radio-capitellar joint. Its chronic injury may lead to radial head instability, elbow pain with decrease in motion and valgus deformity. Method: We present the case of a 53-year-old heavy laborer who reported a complex trauma of the right upper limb with a Floating Elbow Injury, associated to an open Monteggia fracture-dislocation. One month later, despite the definitive fixation with plates of  both the forearm and the supracondylar fractures, X-rays showed the persistence of the radial head dislocation...

BACKGROUND: Peroneal tendinopathies are an under-diagnosed and potentially under-treated pathology. If left untreated it can be a cause of chronic lateral hindfoot pain. Its diagnosis is challenging owing to its low incidence and vague clinical presentation. CASE SUMMARY: We share a case of a patient who experienced a chronic lateral ankle pain exacerbated after alighting from a bus. This patient came to our attention only after failing conservative management on two separate occasions...

Posterior tibial tendon dysfunction (PTTD) is a progressive disorder secondary to advanced degeneration of the posterior tibial tendon, leading to the abduction of the forefoot, valgus rotation of the hindfoot, and collapse of the medial longitudinal arch. Eventually, the disease becomes so advanced that it begins to affect the deltoid ligament over time. This attenuation and eventual tear of the deltoid ligament leads to valgus deformity of the ankle. Surgical correction of PTTD is performed to protect the ankle joint at all costs...

The authors present the cases of 3 patients with severe injuries affecting the peroneal nerve combined with loss of tibialis posterior function (inversion) despite preservation of other tibial nerve function. Loss of tibialis posterior function is problematic, since transfer of the tibialis posterior tendon is arguably the best reconstructive option for foot drop, when available. Analysis of preoperative imaging studies correlated with operative findings and showed that the injuries, while predominantly to the common peroneal nerve, also affected the lateral portion of the tibial nerve/division near the sciatic nerve bifurcation...

INTRODUCTION: Peroneal tendon disorders pose a diagnostic conundrum to the clinician. Magnetic resonance imaging (MRI) is widely used to assess tendon pathology. A recognized artifact of MRI, the magic angle effect (MAE), can lead to spurious results and inappropriate management. The aim of this study is to assess whether T2 fat-suppressed sequences (T2FSs) reduce the frequency of MAE compared with proton density fat-suppressed (PDFS) images. METHODS: MRI scans of 18 patients were prospectively assessed for MAE...

BACKGROUND: The purpose of this study is to describe the relative location of superficial anatomic landmarks and likely location of structures at risk in order to predict the proximity of the later and avoid their injury during the arthroscopic treatment of lateral ankle instability. METHODS: Fifteen cadaver ankles were dissected. Based on superficial anatomic landmarks, the location and distances to the structures at risk (extensor tendons, peroneus tertius, peroneal tendons, main branch or intermediate branch of the superficial peroneal nerve, and the sural nerve) were measured...

The purpose of our study was to examine the preoperative clinical factors and magnetic resonance imaging (MRI) findings associated with peroneal pathology in chronic lateral ankle instability patients, as well as the clinical factors associated with peroneal lesions being detected on MRI. Peroneal pathology was determined from intraoperative findings. Patients with/without peroneal pathology were compared regarding their preoperative clinical findings. MRI reports were examined to determine the sensitivity of detecting peroneal pathologies...

PURPOSE: Evaluating images of the lateral ligament of the ankle is not easy, and evaluation of the calcaneofibular ligament (CFL) in particular is difficult. We prospectively conducted morphological measurements of the CFL in different ankle positions and obtain basic data for use in functional assessment of the CFL, diagnosis of CFL injury, and determination of treatment effects. METHODS: The subjects were ten healthy volunteers (ten ankles) with a mean age of 27...

PURPOSE: Fibular (peroneal) groove morphology may influence fibularis tendon pathology, including tendinosis, tears, and luxation. The study goal was to evaluate the inter-reader agreement of morphologic characterization and measures of the fibular groove at two different levels on MRI and correlation with fibularis tendon pathology. MATERIALS AND METHODS: 47 ankle MRIs in patients without lateral ankle pain were reviewed by two musculoskeletal radiologists. Fibular groove morphology and various measurements were assessed at both the level of the tibial plafond and 1 cm proximal to the tip of the lateral malleolus...

BACKGROUND: Peroneal Tendon (PT) complex is formed by the Peroneus Longus Tendon (PLT) and Peroneus Brevis Tendon (PBT), their synovial sheath, the superior and inferior retinaculum, and the Os Peroneum (OP). Their insertion is associated with some anatomic variability. Knowing these variants helps to understand the PT pathology and it may support the decision-making concerning the operative approach. The purpose of this study was to assess anatomical variability in PT insertion. METHODS: Twenty fresh-frozen cadaveric feet were used...

BACKGROUND: The extensile lateral calcaneal approach is a standard method for accessing a joint depression calcaneal fracture. However, the operative wound complication rate is high. Previous studies showed a calcaneal branch of the peroneal artery contributing to the calcaneal flap blood supply. This study focuses on the location of the vertical limb in this approach correlating to the aforementioned artery and flap perfusion. METHODS: Ten pairs of fresh-frozen cadaveric lower extremities were used...

BACKGROUND: Lateral malleolus (LM) fixation is necessary for unstable ankle fractures. Traditional fixation relies on the use of plates through a lateral incision, wound healing can be an issue for such incisions. A novel intramedullary (IM) fixation device has been developed that can be placed through a minimal incision. The purpose of this study was to demonstrate the clinical efficacy of this device. METHODS: A retrospective analysis was performed on patients who received IM fixation for isolated fibula, bimalleolar (BM), and trimalleolar (TM) fractures...
