Objective:
To determine hip joint pain referral patterns.
Design:
Retrospective analysis. Setting. Multicenter. Patients. Fifty-one consecutive patients meeting clinical criteria of a symptomatic hip joint. Interventions. Fluoroscopically guided intra-articular hip joint injection. Outcome Measures. Anatomic pain map before hip injection and visual analog scale both before and after hip injection.
Results:
The hip joint was shown to cause pain in traditionally accepted referral areas to the groin and thigh in 55% and 57% of patients, respectfully. However, pain referral was also seen in the buttock and lower extremity distal to the knee in 71% and 22%, respectively. Foot and knee pain were seen in only 6% and 2% of patients, respectively, while lower lumbar spine referral did not occur. Fourteen pain referral patterns were observed.
Conclusions:
Buttock pain is the most common pain referral area from a symptomatic hip joint. Traditionally accepted groin and thigh referral areas were less common. Hip joint pain can occasionally refer distally to the foot. Lower lumbar spine referral did not occur.

01:09Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

01:07Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
