Insights

A rare case of primary synovial chondromatosis in a 14-year-old is presented, highlighting shoulder pain and a palpable mass. This condition involves joint nodules and requires surgical removal with follow-up due to recurrence risk.

Area of Science:

  • Orthopedics
  • Pediatric Rheumatology
  • Musculoskeletal Pathology

Background:

  • Primary synovial chondromatosis is a rare condition characterized by the formation of cartilaginous nodules within synovial joints, tendon sheaths, or bursae.
  • While typically affecting large joints in adults, its occurrence in the pediatric population, particularly in the shoulder, is exceptionally uncommon.

Observation:

  • This report details a 14-year-old patient presenting with shoulder pain and a significant palpable mass, with no history of trauma.
  • Clinical findings, advanced imaging, surgical intervention, and histological analysis confirmed primary synovial chondromatosis involving the glenohumeral joint, biceps tendon sheath, and subcoracoid bursa.

Findings:

  • The condition manifested as multiple calcified nodules, leading to symptoms of pain and a palpable mass.
  • Surgical management involved the removal of loose bodies and synovectomy, performed via open and arthroscopic-assisted techniques.

Implications:

  • This case underscores the importance of considering rare diagnoses like primary synovial chondromatosis in pediatric patients with unexplained joint masses and pain.
  • Prompt diagnosis and surgical intervention are crucial, with long-term follow-up recommended due to the potential for recurrence and malignant transformation.

Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Muscles that Move the Arm01:31

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
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...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Bones of the Upper Limb: Humerus01:19

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...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
