Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

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...

Area of Science:

Orthopedic Surgery
Surgical Anatomy

Background:

The deltoideopectoral approach is the standard for proximal humeral fracture treatment.
Minimally invasive surgical techniques are continually being explored.

Purpose of the Study:

To demonstrate the extended deltoid approach as a viable alternative for proximal humeral fracture surgery.
To highlight the technique's advantages in visualization and implant placement.

Main Methods:

A direct lateral incision was utilized.
The anterior portion of the axillary nerve was identified and carefully preserved.
Intraoperative video documentation was employed.

Main Results:

The extended deltoid approach facilitated improved visualization of the greater tuberosity.
Easier positioning of locking plates was achieved.
No clinically relevant neurological injuries were observed in patients or reported in the literature.

Conclusions:

The extended deltoid approach is a safe and effective alternative for surgical treatment of proximal humeral fractures.
This technique offers significant advantages in surgical exposure and hardware placement.
Axillary nerve preservation is achievable with this approach.
