Summary
This study created a probabilistic atlas of clavicle muscle footprints, revealing significant variation. Patient-specific implants are recommended to avoid interfering with these muscle insertion footprints (MIF).
Area of Science:
- Anatomy
- Biomechanics
- Medical Imaging
Background:
- Clavicle muscle footprint anatomy is described in textbooks, but variations are under-researched.
- Understanding muscle footprint variation is crucial for orthopedic procedures involving the clavicle.
Purpose of the Study:
- To assess the variation in clavicle muscle footprint anatomy.
- To create a probabilistic atlas of clavicle muscle footprints.
Main Methods:
- Dissection of 14 clavicles, followed by 3D modeling using CT scanning, laser scanning, and photogrammetry.
- Calculation of mean clavicles and non-rigid registration to map muscle footprints.
- Generation of probabilistic atlases based on registered muscle footprints.
Main Results:
- No significant differences in muscle footprint surface area were found between sexes or sides.
- Muscle footprints covered 72% (right) and 82% (left) of the mean clavicle surface area.
- Significant variation in muscle footprint location was observed, indicating no universal clavicle anatomy.
Conclusions:
- The study highlights considerable variation in clavicle muscle footprint anatomy.
- Patient-specific clavicle fracture fixation plates are recommended to minimize interference with muscle insertion footprints (MIF).
- This research supports personalized approaches in clavicle fracture treatment.

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:19Bones of the Upper Limb: Humerus
6.7K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

The connective tissues play a significant role in arranging the muscle fibers into a hierarchical structure that forms a complete muscle. Consider a muscle like the bicep brachii, commonly called the bicep. This muscle comprises thousands of muscle fibers enclosed by a protective layer of connective tissue called the endomysium. The endomysium is primarily composed of reticular fibers, a type of thin collagen fiber. It allows the exchange of nutrients and waste products at the fiber level,...
