The deep peroneal nerve is marked by connecting the following points: The first point is on the lateral side of the fibula neck.The second point is on the anterior aspect of the ankle in the midpoint between the two malleoli.The third point is at the first interosseous space.
Knee Pain
Published in Benjamin Apichai, Chinese Medicine for Lower Body Pain, 2021
The lower leg is made up of two bones, the tibia and fibula. The fibula is the slender one and posterolaterally situated to the tibia. It is a non-weight-bearing bone. These two bones are connected at two locations: Proximal tibiofibular joint—the fibula articulates with the inferior aspect of the lateral tibial condyle. It is supported by a tense joint capsule; the capsule attaches to the tibia and fibula at the margin of the articular surface and is reinforced anteriorly by the biceps femoris tendon insertion into the fibular capitulum, posteriorly by the popliteus tendon, superiorly by the lateral collateral ligament, and inferiorly by the interosseous membrane.Distal tibiofibular joint—the fibula articulates with the fibular notch of the tibia.

Type C – a fracture of the fibula above the level of the tibiofibular syndesmosis. This is often indicative of a more severe injury due to the forces extending through the syndesmotic ligaments. The fracture pattern of the fibula is often comminuted.

The tibia and fibula geometries were segmented using a semi-automatic procedure and surface meshes were created in the Mimics Innovation Suite (v21, Materialise, Leuven, Belgium). Nodal correspondence and registration were performed in MATLAB (R2020a, Mathworks, MA, USA). A template mesh was selected, corresponding to an individual with tibia/fibula surface area close to the sample mean, and contained 3874 and 2111 nodes for the tibia and fibula, respectively. A sensitivity analysis, evaluating shape errors resulting from the template deformation step, was used to determine the number of nodes for the tibia and fibula. Nodal correspondence between meshes was established using the Coherent Point Drift algorithm (Myronenko and Song 2010). This algorithm performs translation, rotation, scaling, and local deformation to match a moving point-set (template) to a fixed point-set (participant surface). A nearest neighbours algorithm was used to identify corresponding points. A preliminary analysis of nodal correspondence registration errors and the number of principal components needed to explain 95% of the variance demonstrated these measures were insensitive to the choice of template. Tibia and fibula point clouds were then combined and rigidly aligned using a generalized Procrustes analysis that retained bone size. The tibia and fibula were modelled together to include relative positioning between the two bones within the model.
Effect of hinge length on the lateral cortex fracture in high tibia osteotomy: an XFEM study
Published in Computer Methods in Biomechanics and Biomedical Engineering, 2022
The archived computerized tomography (CT)-scanned images of a 36-year-old male candidate for HTO with medial mechanical proximal tibia angle (mMPTA) of 81° were used to construct a three-dimensional tibial computer-aided design. The CT images, with 1 mm slice, were manipulated in Mimics V19.0, (Materialise, Leuven, Belgium), and then imported into CATIA V5R19 (Dassault System Velizy-Villacoublay) where a 1.2 mm thick cutting path was created to represent the bone removal by saw. The lateral hinge almost has the highest stress concentration in the osteotomized tibia. Figure 1 shows the bone removal section by saw and Takeuchi’s classification of lateral hinge fracture. Its fracture was evaluated by changing two parameters: the hinge length (H) and the medial starting osteotomy point below the articular surface (M). The hinge length was defined as the distance between points a and b (Figure 2), which was the start point and end point of the hinge, respectively. The cutting plane was kept parallel to the tibial slope in the sagittal plane. The effect of four hinge lengths of 5, 10, 16, and 22 mm was investigated on the crack initiation and direction. The cutting path on the lateral side was up to the top of the fibula bone (Han et al. 2013). On the medial side, the distance between points c and d (M) was 30, 35, and 40 mm below the articular surface of the tibia (Figure 2). Finally, a total of twelve models were studied by assigning the abovementioned values to each of the two parameters.

The second generation PRECICE (P2) limb-lengthening system (NuVasive, San Diego, CA, USA) was used in all individuals (Table 2, Figures 3–4, for Figures 2 and 5, see Supplementary data). The patients were placed in a supine position on a radiolucent surgical table. All nails were implanted retrogradely according to the preoperative planning (Figure 2, see Supplementary data). The corticotomy was performed on the distal tibia with a multiple drill hole technique and subsequent chiseling. In patients with distal malalignment (Nos 4 and 6) a single osteotomy was carried out on the apex deformity for realignment and callus distraction. In the patient with mid-shaft valgus deformity (No. 9) a second osteotomy was executed on the apex of the deformity for angular correction in addition to a distal corticotomy for callus distraction. The mid-shaft osteotomy was bridged by the ILN and additionally fixed using a 4-hole 3.5 mm locking plate (VariAx, Stryker, Kalamazoo, MI, USA) to prevent proximal distraction (Figure 4). If present, the fibula was osteotomized at the border from the proximal to the distal third (n = 7). Adequate function of the implanted ILN was fluoroscopically proven by intraoperative distraction of 1 mm. In 6 patients 7 concomitant operations were performed (Table 2).
