“A comparison of epidural levobupivacaine 0.5% with racemic bupivacaine 0.5% for lower abdominal surgery” A study on morphometric study of nutrient for amina of fibula
Keywords:Fibula; Foraminalindex; Nutrientforamen; Vascularised fibular graft.
Background and objectives: In the leg, the fibula is placed lateral to the tibia. Because of its length, biomechanical stability, reduced donor site morbidity, and predictable vascular pedicle, the fibula is the bone of choice for grafting and rebuilding major defects after tumour removal. The study's objectives are as follows: (1) to locate and describe the site, number, and orientation of fibula nutritional foramina. (2) To look for differences in the location, position, and quantity of nutrition foramina in the fibula. Methods: The study sample consisted of 100 dry adult human fibulae (107 right and 93 left) from Kakatiya Medical College's Department of Anatomy. Fibulae were gathered from our institution's undergraduate medical students at KMC, Warangal. The data relevant to the aforementioned criteria were recorded, subjected to statistical analysis, and photographed. Results: In the present study of 100 dry adult human fibulae, noted;
i. The absence of nutritional foramen (NF) in 12 (6%) of the fibulae.
ii. A single nutritional foramen was found in 87 (87.0 percent) of the fibulae.
iii. Nearly 8 percent of the fibulae had twin nutrient foramen.
iv. 1 (1%) fibulae had triple nutrient foramen.
v. The total number of nutrient foramen in 94 fibulae was 100.
vi. The most common site of nutritional foramen was on the medial crest in 42 (43.75 percent) of the fibulae and the least common on the anterior border in 1 (1.04 percent).
vii. 90 (95.0 percent) of the foramen were located in the middle region of the fibula.
viii. h88 (93.61%) foramen were directed away from the developing end (AFGE), 15 (15.94%) towards the growing end of the fibula.
Interpretation and conclusion: The number of nutrient foramen varied by 13.5 percent in the current study. Orthopaedic and plastic surgeons can plan the vascularised fibular graft at the middle third of the shaft with accurate anatomical knowledge about the location and distribution of the nutrient foramen.
