MRI-based anatomical characterisation of lower-limb muscles in older women

et al. 2020

The ability of muscles to produce force depends, among others, on their anatomical features and it is altered by ageing-associated weakening. However, a clear characterisation of these features, highly relevant for older individuals, is still lacking. This study hence aimed at characterising muscle volume, length, and physiological cross-sectional area (PCSA) and their variability, between body sides and between individuals, in a group of post-menopausal women. Lower-limb magnetic resonance images were acquired from eleven participants (69 (7) y. o., 66.9 (7.7) kg, 159 (3) cm). Twenty-three muscles were manually segmented from the images and muscle volume, length and PCSA were calculated from this dataset. Personalised maximal isometric force was then calculated using the latter information. The percentage difference between the muscles of the two lower limbs was up to 89% and 22% for volume and length, respectively, and up to 84% for PCSA, with no recognisable pattern associated with limb dominance. Between-subject coefficients of variation reached 36% and 13% for muscle volume and length, respectively. Generally, muscle parameters were similar to previous literature, but volumes were smaller than those from in-vivo young adults and slightly higher than ex-vivo ones. Maximal isometric force was found to be on average smaller than those obtained from estimates based on linear scaling of ex-vivo-based literature values. In conclusion, this study quantified for the first time anatomical asymmetry of lower-limb muscles in older women, suggesting that symmetry should not be assumed in this population. Furthermore, we showed that a scaling approach, widely used in musculoskeletal modelling, leads to an overestimation of the maximal isometric force for most muscles. This heavily questions the validity of this approach for older populations. As a solution, the unique dataset of muscle segmentation made available with this paper could support the development of alternative population-based scaling approaches, together with that of automatic tools for muscle segmentation.

“…The branch of the deep femoral artery located at the apex of the blood supply branch of the sartorius muscle pedicle iliac bone is the most important blood supplier of the sartorius muscle. 25 Special attention should be paid to protect these blood vessels when freeing the iliac crest flap. During surgery, the blood supply of the bone flap can be confirmed by observing the amount of bleeding at the cutting end of the bone flap.…”

Purpose Despite the early diagnosis and treatment of developmental dysplasia of the hip (DDH), some older children still need open reduction. It is usually difficult to get a satisfactory reduction particularly in patients with acetabular defect. The purpose of this study was to evaluate the short-term outcomes of acetabulum reaming and sartorius muscle pedicle iliac bone grafting in the treatment of older children with DDH and acetabular defect. Methods The records of 15 patients with DDH (mean age 113.9 months (sd 29); 17 hips) who were treated with the reported technique between February 2015 and January 2017 were retrospectively reviewed. All patients acquired regular clinical and radiographic follow-ups, and alterations in the acetabular index, centre-edge angle and acetabular head index were measured. Joint function and radiographic results were evaluated with McKay and Severin modified criteria, respectively. Results A total of 15 patients were followed up for mean 32.4 months (sd 6.9). The percentages of excellent and good conditions were 94.1% (16/17) according to the Severin modified criteria and 88.2% (15/17) according to the McKay modified criteria. Avascular necrosis of the femoral head and redislocation only occurred in one hip. No cases of ankylosis or bone graft absorption occurred during the follow-up. Conclusion Reaming the acetabulum and sartorius muscle pedicle iliac bone grafting for repairing the acetabular defect can recover the arcuate structure by increasing the volume of the acetabulum, which is beneficial for achieving a concentric reduction. The short-term outcome was satisfactory, while the long-term results need to be further observed. Level of Evidence IV – retrospective study

“…Long intramuscular course of the tendon enables attachment of a significantly greater number of muscle fibres in the distal area of the tendon. Intramuscular course of tendons is an insufficiently investigated and rarely described anatomical phenomenon [9] with potentially significant biomechanical and clinical implications.…”

Ten human gracilis muscles obtained from adults and ten gracilis muscles collected from human foetuses between the 15th and 21st week of gestation were examined. The results of this preparatory study show that the gracilis muscle in adults is narrow and long - 482 mm on average. The distal tendon of gracilis muscle is long, 294 mm on average. It can be divided into two sections - external part, outside the muscle belly, and internal, intramuscular, part. The latter one is partially covered by muscle fibres and some of it is completely hidden inside the muscle belly, which is on average 76 mm long. Presence of an intramuscular part of the distal tendon was also demonstrated in the foetal material. Moreover, very strong correlations between particular muscle lengths were noted in foetuses.
