23 Possible Causes for Flattened Humeral Head

  • Rotator Cuff Tendinitis

    This is due to the limited contact area of the glenoid with the humeral head, flattened architecture, and retroverted positioning.[emedicine.medscape.com]

  • Shoulder Osteoarthritis

    The normally rounded surface of the humeral head may also begin to flatten out.[arthritis-health.com] Primary OA demonstrates humeral osteophytes, humeral head flattening, irregular/narrowed joint space, subchondral cystic changes in humeral head and posterior glenoid wear[eorif.com] Large osteophytes may grow on the humeral head in a curved pattern, sometimes called a “goat’s beard.”[arthritis-health.com]

  • Shoulder Impingement Syndrome

    head flattening; proceeds to degenerative arthritis NSAIDs, physical therapy, hemi- or total shoulder arthroplasty Cervical radiculopathy Radiating pain below shoulder or[aafp.org] NSAIDs Avascular necrosis Predisposing factors such as steroid use, trauma, alcoholism; frequently idiopathic; painful motion Early radiographs normal; later radiographs show humeral[aafp.org]

  • Rotator Cuff Tear

    This is due to the limited contact area of the glenoid with the humeral head, flattened architecture, and retroverted positioning.[emedicine.com]

  • Fracture of the Cribriform Plate

    The humeral head will protrude anteriorly underneath the pectoris major on the anterior chest wall.[books.google.com] The shoulder joint will usually be locked, and the shoulder will appear squared off or flattened.[books.google.com]

  • Shoulder Dislocation

    .  Subglenoid (anteroinferior):  humeral head sits inferior and slightly anterior to the glenoid, that the humeral head has also travelled medially.  30% of cases. 8.[slideshare.net] Other  POSTERIOR:  Different mechanisms: seizure, electrocution.  Present with flattened anterior shoulder and prominent coracoid.  Can easily go unrecognised.  INFERIOR[slideshare.net]

  • Bone Necrosis

    Radiographic findings are delayed; they include flattening, sclerosis, and irregularity of part of the articular surface of the humeral head.[emedicine.medscape.com] Osteonecrosis of the humeral head is usually a complication of a fracture of the anatomic neck or severe fracture dislocation.[emedicine.medscape.com]

  • Avascular Necrosis

    Radiographic findings are delayed; they include flattening, sclerosis, and irregularity of part of the articular surface of the humeral head.[emedicine.medscape.com] Osteonecrosis of the humeral head is usually a complication of a fracture of the anatomic neck or severe fracture dislocation.[emedicine.medscape.com]

  • Smith-McCort Dysplasia

    Smith-McCort dysplasia (SMC OMIM 615222) and Dyggve-Melchior-Clausen dysplasia (DMC OMIM 223800) are allelic skeletal dysplasias caused by homozygous or compound heterozygous mutations in DYM (OMIM 607461). Both disorders share the same skeletal phenotypes characterized by spondylo-epi-metaphyseal dysplasia with[…][ncbi.nlm.nih.gov]

  • Myocardial Contusion

    The humeral head will protrude anteriorly underneath the pectoris major on the anterior chest wall.[books.google.de] The shoulder joint will usually be locked, and the shoulder will appear squared off or flattened.[books.google.de]
