24 Possible Causes for Flattened Humeral Head

  • 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]

  • 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]

  • Schimke Immunoosseous Dysplasia

    Skeleton of upper limbs: deformed and flattened humeral head, humerus short. al-antitrypsin were normal for age.[docslide.com.br] Shoulder width, ankle width ( 3 standard deviation), and the occipital-frontal head circumference (272 Santava et al. Figs. 4 and 5.[docslide.com.br]

  • Shoulder Osteoarthritis

    The normally rounded surface of the humeral head may also begin to flatten out.[arthritis-health.com] Compensatory bone changes may even cause the humeral head’s rounded surface to flatten and/or large osteophytes to grow on the humeral head in the form of a “goat’s beard.[arthritis-health.com] Large osteophytes may grow on the humeral head in a curved pattern, sometimes called a “goat’s beard.”[arthritis-health.com]

  • Shoulder Dislocation

    The head of the humerus may impact against the anterior-inferior edge of the glenoid causing a divot or flattening of the humeral head, Hill-Sachs Lesion (Figure 6).[huffingtonpost.com] .  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]

  • Paraldehyde

    In patients who are skeletally immature, humeral head flattening and morphological changes can be described acromiale.[medicaldb.blogspot.com] Radiological assessment of glenohumeral joint stability may be difficult due to changes in forcing subduction scapular humeral head position.[medicaldb.blogspot.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]

  • Erb Duchenne Palsy

    […] of the humeral head; - diff dx: - pseudoparalysis resulting from clavicle and humerus fractures or osteomyelitis must be excluded; - see: clavicular frx in infants ; - prognosis[wheelessonline.com] […] normal side; - w/ increasing retroversion, there will be associated subluxation, dislocation (w/ development of false glenoid), and w/ increasing severity, there will be flattening[wheelessonline.com]

  • Rotator Cuff Tear

    head flattening; proceeds to degenerative arthritis NSAIDs, physical therapy, hemi- or total shoulder arthroplasty Cervical radiculopathy Radiating pain below shoulder or[aafp.org] This is due to the limited contact area of the glenoid with the humeral head, flattened architecture, and retroverted positioning.[emedicine.medscape.com] NSAIDs Avascular necrosis Predisposing factors such as steroid use, trauma, alcoholism; frequently idiopathic; painful motion Early radiographs normal; later radiographs show humeral[aafp.org]
