Ball joints consist of an approximately spherical joint head and a correspondingly hollowed-out socket.
Typical ball joints include:
Ball joints have an infinite number of axes of movement, but from a functional point of view three main axes are defined, so that these are joints with three degrees of freedom. This is done around a sagital axis:
As Nut joint Joints are referred to in which the joint socket extends beyond the equator of the joint head.
Egg joints have elliptical joint bodies with two joint bodies perpendicular to one another. Two degrees of freedom are possible and thus four main movements are possible.
These are typical egg joints body-hugging wrist and the head joints between the occiput and first cervical vertebra (Atlas).
Hinge, wheel or pin joints are also referred to as roller joints. In the case of hinge joints, it intervenes cylindrical joint body into the groove-shaped recess of a hollow cylindrical joint body.
Hinge joints only have a degree of freedom. Typical hinge joints are:
At wheel- or Pivot joints is a cylindrical skeleton element with a corresponding part of a Hollow cylinder and a ring or cross band in connection. Only rotary movements around one axis are possible here.
Saddle joints have saddle-shaped curved joint surfaces whose two main axes of movement are perpendicular to one another. Rotational movements are only possible with the loss of contact between the two joint surfaces. The Saddle thumb joint is a typical saddle joint.
Plane joints have almost flat joint surfaces and allow shifting and rotating movements in one plane. The small Vertebral joints are among the planar joints.
As tight joints (Amphiarthroses) are joints whose mobility is severely restricted by tight ligaments. This includes the body-hugging Shin-fibula joint (Tibiofibular joint) as well as thatSacrum joint (Sacroiliac joint).

Who am I?
My name is dr. Nicolas Gumpert. I am a specialist in orthopedics and the founder of .
Various television programs and print media report regularly about my work. On HR television you can see me every 6 weeks live on "Hallo Hessen".
But now enough is indicated ;-)
In order to be able to treat successfully in orthopedics, a thorough examination, diagnosis and a medical history are required.
In our very economic world in particular, there is too little time to thoroughly grasp the complex diseases of orthopedics and thus initiate targeted treatment.
I don't want to join the ranks of "quick knife pullers".
The aim of any treatment is treatment without surgery.
Which therapy achieves the best results in the long term can only be determined after looking at all of the information (Examination, X-ray, ultrasound, MRI, etc.) be assessed.
You will find me:
You can make an appointment here.
Unfortunately, it is currently only possible to make an appointment with private health insurers. I hope for your understanding!
