"&amp;lt;p&amp;gt;The glenoid is the socket of the &amp;lt;a href=&amp;quot;https://www.verywell.com/shoulder-anatomy-2549240&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;1&amp;quot;&amp;gt;ball-and-socket shoulder joint&amp;lt;/a&amp;gt;.\u00A0 The glenoid is part of the scapula (shoulder blade), a thin, broad bone that sits behind the rib cage.\u00A0 The scapula itself is mobile (its orientation shifts on your back with movement), and normal scapular motion is important for normal shoulder function.\u00A0&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;The glenoid is a projection of the outer side of the scapula.\u00A0 The glenoid socket is not too deep (unlike the hip joint socket), rather, the glenoid socket is a shallow, almost flat part of the bone.\u00A0 The glenoid surface is covered by articular cartilage--the smooth lining of normal joints.\u00A0 The socket of the glenoid is deepened by another type of cartilage, called the &amp;lt;a href=&amp;quot;https://www.verywell.com/labral-tear-torn-shoulder-labrum-2549805&amp;quot;

data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;5&amp;quot;&amp;gt;shoulder fracture&amp;lt;/a&amp;gt;.\u00A0 Glenoid fractures most often occur when there is significant trauma to the shoulder, or as a result of high-energy sports injuries.\u00A0 The two most common fracture patterns are:&amp;lt;/p&amp;gt;&amp;lt;ul&amp;gt;&amp;lt;li&amp;gt; &amp;lt;strong&amp;gt;Glenoid Lip Fractures:&amp;lt;/strong&amp;gt; Glenoid lip fractures occur when there is a &amp;lt;a href=&amp;quot;https://www.verywell.com/shoulder-dislocation-2548791&amp;quot;

data-ordinal=&amp;quot;7&amp;quot;&amp;gt;shoulder subluxation&amp;lt;/a&amp;gt;, and the ball comes out of the socket.\u00A0 As the ball dislocates, it can push against the rim of the glenoid socket, causing a fragment of the bone to fracture.&amp;lt;p&amp;gt;Treatment of a glenoid rim fracture is focused on restoring the normal contour of the shoulder socket to prevent recurrent instability (repeat dislocations) of the shoulder joint.\u00A0 Surgical treatment is often considered for these injuries, especially when the fracture is out of position or if there is a large fragment of the glenoid bone.&amp;lt;/p&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt; &amp;lt;strong&amp;gt;Glenoid Fossa Fractures:&amp;lt;/strong&amp;gt;\u00A0 The glenoid fossa is the center portion of the socket.\u00A0 Glenoid fossa fractures are much less common injuries, and often associated with severe trauma.\u00A0 There is little data on the ideal treatment of these injuries, because they are so uncommon.\u00A0 However, most surgeons agree that fracture management decisions must take into account both the fracture type and the patient&amp;amp;#39;s need.\u00A0 More active patients with fractures that are not in proper position will most likely benefit from surgery to realign these injuries.&amp;lt;/li&amp;gt;&amp;lt;/ul&amp;gt;&amp;lt;h3&amp;gt;Glenoid Fracture Treatment&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;Treatment of glenoid fractures can be controversial as there have been very few studies to compare different treatment methods.\u00A0 Because these are uncommon injuries, it is difficult to perform comparison studies as even specialized surgeons may only treat these types of injuries infrequently.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;In general, it is agreed that if there is damage to the cartilage surface of the glenoid, then surgery is a reasonable treatment.\u00A0 The goal of surgical treatment is to restore the alignment of the normal joint surface.\u00A0 It is typical to repair the bone with small plates and/or screws to ensure that the bones heal in the proper position.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Rehabilitation after surgery to repair a glenoid fracture is focused on restoring normal mobility and strength to the shoulder joint.\u00A0 Your surgeon may recommend a brief time of immobilization to allow the bones to begin to heal, but as soon as possible will begin &amp;lt;a href=&amp;quot;https://www.verywell.com/what-is-range-of-motion-2552138&amp;quot;
