Bone Markings

8.6K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Growth of Cartilage and Bone Tissue

4.5K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Bone Formation by Endochondral Ossification

10.6K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Summary

The chondral print (CP) sign is not reliably linked to biceps tendon issues or rotator cuff tears. It is, however, associated with age and superior labral anteroposterior (SLAP) lesions.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Shoulder Arthroscopy

Background:

  • The chondral print (CP) sign denotes a specific chondral alteration on the humeral head, situated beneath the long head of the biceps (LHB) tendon.
  • The exact pathological mechanism and causative factors of the CP sign remain unclear despite various proposed associations.

Purpose of the Study:

  • To investigate the association between the chondral print (CP) sign and pathologies of the long head of the biceps (LHB) tendon, rotator cuff, labrum, and other chondral lesions.
  • To determine the clinical significance and diagnostic reliability of the CP sign in shoulder arthroscopy.

Main Methods:

  • Prospective cohort association study involving 102 consecutive shoulder arthroscopies.
  • Data collected using a specialized pro forma, including CP sign identification and associated pathologies.
  • Statistical analysis performed to evaluate correlations between CP sign and various shoulder conditions.

Main Results:

  • The CP sign was identified in 23.5% of patients (mean age 58 years).
  • Significant positive association found between the CP sign and superior labral anteroposterior (SLAP) tears (including type 1).
  • No statistically significant association was found between the CP sign and LHB instability, other LHB pathologies, or rotator cuff tears.

Conclusions:

  • The CP sign is not a reliable indicator of long head of the biceps (LHB) instability or other LHB pathologies.
  • A positive association exists between the CP sign, increasing age, and degenerative SLAP lesions.
  • The study could not establish a definitive cause for the chondral print sign.
