Displaced Fracture Dislocation of the Proximal Humerus
The Journal of Orthopaedic and Sports Physical Therapy
|September 2, 2018
Summary
A 41-year-old skier experienced a proximal humerus fracture dislocation. Surgical repair was followed by physical therapy, with imaging and exams guiding treatment.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Physical Therapy
Background:
- Proximal humerus fractures are common injuries, particularly in active individuals.
- Fracture dislocations require prompt surgical intervention and rehabilitation.
Observation:
- A 41-year-old male skier sustained a right shoulder injury from a fall.
- Emergency department radiographs revealed a 3-part fracture dislocation of the proximal humerus.
Findings:
- The patient underwent same-day surgical repair for the proximal humerus fracture dislocation.
- Physical therapy commenced on postoperative day 27.
- Postoperative imaging and physical assessments informed the patient's care plan.
Implications:
- Early surgical management and structured physical therapy are crucial for treating complex proximal humerus fractures.
- Multimodal assessment, including imaging and clinical examination, is vital for optimizing patient recovery.
- This case highlights the importance of timely intervention and tailored rehabilitation in ski-related shoulder injuries.

Bones of the Upper Limb: Humerus
7.2K
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...

Displacement Current

Ampère's law, in its usual form, does not work in places where the current changes with time and is not steady. Thus, Maxwell suggested including an additional contribution, called the displacement current, Id, to the real conduction current I.

Position and Displacement
26.2K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Position and Displacement Vectors

To describe the motion of an object, one should first be able to describe its position (where it is at any particular time). More precisely, the position needs to be specified relative to a convenient frame of reference. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference to describe the position of an object in relation to stationary objects on Earth.

Significance of Displacement Current
5.9K
A displacement current is analogous to a real current in Ampère's law, participating in Ampère's law the same way as the usual conduction current. However, it is produced by a changing electric field. Displacement current is defined in terms of a time-varying electric field, and also has an associated displacement current density. By adding a term accounting for displacement current, Maxwell modified the existing Ampère's law, which is now called generalized Ampère's law.

Angular Velocity and Displacement
22.9K
Uniform circular motion is motion in a circle at a constant speed. Although this is the simplest case of rotational motion, it is very useful for many situations and is used to introduce rotational variables. When a particle is moving in a circle, the coordinate system is fixed and serves as a frame of reference to define the particle’s position. Its position vector from the origin of the circle to the particle sweeps out the angle θ, which increases in the counterclockwise direction...
