Entrapment neuropathies of the fibular nerve and its branches are often underdiagnosed due to the lack of reliable diagnosis using clinical examination and electrophysiologic evaluation. Most fibular nerve compressions may be classified into 2 broad categories: (a) mechanical causes, which occur at fibrous or fibro-osseous tunnels, and (b) dynamic causes related to nerve injury during specific limb positioning. Foot drop resulting from weakness of the dorsiflexor muscles of the foot is a relatively uncommon presentation and closely related to L5 neuropathy caused by a disc herniation...

INTRODUCTION: Syndesmotic disruption may be difficult to reduce and fix, and malreduction is associated with inferior outcomes. Intraoperative computed tomography (CT) can provide accurate assessment of syndesmotic reduction. We hypothesized that three-dimensional (3-D) computer-assisted orthopaedic surgery (CAOS) with navigation of syndesmotic reduction could avoid malreduction. Our goal was to assess feasibility and accuracy of such a technic in a cadaveric study. METHOD: Eleven through-the-knee cadaveric specimens were used...

BLACKGROUND: In the last couple of years dynamic fixation for syndesmosis injuries, using a suture-button technique, raised more interest due to its advantages over the static fixation. In the current systematic review suture-button fixation is compared to the traditionally applied static fixation in unstable ankle fractures accompanied with distal tibiofibular syndesmosis injury, including the functional outcome, post-operative complications, reoperation rate, recurrent diastasis and financial aspects...

Background Although proximal fibular flaps have been widely applied in wrist arthroplasty, controversy remains regarding which side of the proximal fibula is better for reconstruction of the distal radius. If the articular surface of the proximal fibula shows dorsal tilting, the ipsilateral (right) proximal fibula should be harvested in right wrist arthroplasty because the articular surface of the distal radius normally has volar tilt. This study investigated anatomical similarities between the proximal fibular articular surface and the distal radius articular surface based on morphologic analysis of the proximal fibula using computed tomography (CT)...

BACKGROUND/PURPOSE: There have been no studies assessing the optimal biomechanical tension of suture button constructs. The purpose of this study was to assess optimal tensioning of suture button fixation and its ability to maintain reduction under loaded conditions using a stress computed tomography (CT) model. METHODS: Ten cadaveric lower limbs disarticulated at the knee were used. The limbs were placed in a modified ankle load frame that allowed for the application of sustained torsional axial, or combined torsional/axial loads...

Because of their frequency, ankle sprains are of major clinical and economic importance. The simple sprain with uneventful healing has to be distinguished from the potentially complicated sprain which is at risk of transition to chronic ankle instability. Conservative treatment is indicated for the acute, simple ankle sprain without accompanying injuries and also in cases of chronic instability. If conservative treatment fails, good results can be achieved by anatomic ligament reconstruction of the lateral ankle ligaments...

BACKGROUND: Despite the common occurrence of syndesmotic injuries in ankle trauma, the distal tibiofibular relationship remains poorly understood. The aim of this study was to evaluate the anatomical impact of ankle sagittal positioning on the tibiofibular relationship in intact ankles by using a validated magnetic resonance imaging (MRI)-based measurement system. METHODS: In this radiologic study, 34 healthy volunteers underwent a series of ankle MRIs with the ankle stabilized in 3 positions: neutral position (NP), dorsiflexion (DF), and plantarflexion (PF)...

BACKGROUND: Historically, syndesmosis injuries have been repaired with screw fixation; however, some suggest that suture-button constructs may provide a more accurate anatomic and physiologic reduction. The purpose of this study was to compare changes in the volume of the syndesmotic space following screw or suture-button fixation using a preinjury and postoperative 3-D computed tomography (CT) model. The null hypothesis was that no difference would be observed among repair techniques...

INTRODUCTION: Various methods using CT scan have been described to diagnose distal tibiofibular syndesmotic injuries. However, CT scan does not take into account the amount of cartilage within the distal tibiofibular joint and could therefore lead to false positive results. We present the first study correlating the findings of the distal tibiofibular syndesmosis on CT and MRI scans. METHODS: CT and MRI scan of consecutive patients over a period of 18 months, and of a time lapsed less than 12 months between the two imaging modalities, were reviewed...

BACKGROUND: Biomechanical data and contributions to ankle joint stability have been previously reported for the individual distal tibiofibular ligaments. These results have not yet been validated based on recent anatomic descriptions or using current biomechanical testing devices. METHODS: Eight matched-pair, lower leg specimens were tested using a dynamic, biaxial testing machine. The proximal tibiofibular joint and the medial and lateral ankle ligaments were left intact...

BACKGROUND: Significant debate exists regarding optimal repair for unstable syndesmosis injuries. Techniques range from screw fixation, suture-button fixation, or a combination of the two. In this study, 3 common repairs were compared using a simulated weightbearing protocol with internal and external rotation of the foot. METHODS: Twenty-four lower leg specimens with mean age 54 years (range, 38-68 years) were used for testing. Following creation of a complete syndesmotic injury (AITFL, ITFL, PITFL, interosseous membrane), specimens were repaired using 1 of 3 randomly assigned techniques: (1) one 3...

INTRODUCTION: Ankle fractures comprise a highly morphologically and etiologically diverse group of injuries, which includes various degrees of impairment of bone and ligamentous structures. The complete synostosis and incomplete bony bridging of tibiofibular syndesmosis are among the local late complications after surgically treated ankle fractures. PATIENTS AND METHOD: 269 patients were evaluated, including 203 patients with Weber type-B fractures, and 66 patients with Weber type-C fractures...

BACKGROUND: The hypothesis of this study is that a sprain or tear of 1 or more of the 3 syndesmotic ligaments will result in a significant change in the osseous anatomy relationship when comparing injured to uninjured syndesmosis. Our secondary objective was to determine whether injuries to the syndesmosis as diagnosed on magnetic resonance imaging (MRI) could be found using static imaging. METHODS: This is a descriptive radiological study of ankle MRI reports over a 12-year period, from 2 different institutions, and divided in two groups: normal and injured syndesmotic ligaments...

PURPOSE: To clarify the fibular head insertion of the fibular collateral ligament (FCL), popliteofibular ligament (PFL), and biceps femoris tendon and related osseous landmarks on three-dimensional (3-D) images. METHODS: Twenty-one non-paired, formalin-fixed human cadaveric knees were evaluated in this study. The fibular head insertions of the FCL, PFL and biceps femoris tendon were identified and marked. 3-D images were created, and the surface area, location, positional relationships, and morphology of the fibular insertions of the FCL, PFL, and biceps femoris tendon and related osseous structures were analysed...

: Ankle fractures are a common injury treated by orthopaedic surgeons. The distal tibiofibular syndesmosis can be injured during these fractures as well as in isolation. They pose a significant challenge with regard to the diagnosis of instability as well as evaluating reduction after fixation. Multiple studies have demonstrated that traditional radiographic analysis fails to accurately identify syndesmotic diastasis, instability, or malreduction. Ankle arthroscopy has been proposed as an alternative way to evaluate the syndesmosis...

BACKGROUND: Excessive internal or external tibial torsion is frequently present in children with cerebral palsy. Several surgical techniques have been described to correct excessive tibial torsion, including isolated distal tibial rotation osteotomy (TRO). The anatomic changes surrounding this technique are poorly understood. The goal of the study was to examine the anatomic relationship between the tibia and fibula following isolated distal TRO in children with cerebral palsy. METHODS: Twenty patients with 29 limbs were prospectively entered for study...

Opening wedge high tibial osteotomy (OWHTO) is a surgical procedure that aims to correct the weight-bearing axis of the knee, moving the loads laterally from the medial compartment. Conventional indications for OWHTO are medial compartment osteoarthritis and varus malalignment of the knee; recently OWHTO has been used successfully in the treatment of double and triple varus. OWHTO, in contrast to closing wedge high tibial osteotomy, does not require fibular osteotomy or peroneal nerve dissection, or lead to disruption of the proximal tibiofibular joint and bone stock loss...

REVIEW

There are a number of variations in the intra-articular anatomy of the ankle which should not be considered pathological under all circumstances. The anteromedial corner of the tibial plafond (between the anterior edge of the tibial plafond and the medial malleolus) can have a notch, void of cartilage and bone. This area can appear degenerative arthroscopically; it is actually a normal variant of the articular surface. The anterior inferior tibiofibular ligament (AITF) can possess a lower, accessory band which can impinge on the anterolateral edge of the talar dome...

INTRODUCTION: Three-dimensional (3D) behavior of the talocrural joint is primarily determined by the articular surface morphology of the talar trochlea and tibiofibular mortise. However, morphological features of the anterior and posterior regions of the talar trochlea remain unclear. The objectives of this study were to evaluate anterior and posterior radii of the medial and lateral talar trochlea and to estimate subject-specific kinematics of the talocrural joint. MATERIALS AND METHODS: Fifty dry tali were scanned using computed tomography to create 3D bone models...
