Absorption of the Bone Fragment in Shoulders With Bony Bankart Lesions Caused by Recurrent Anterior Dislocations or Subluxations

Abstract

Bone fragment absorption was seen in all of the shoulders with bony Bankart lesions. Most bone fragments showed severe absorption within 1 year after the primary traumatic episode. Before arthroscopic Bankart repair, not only glenoid defects but also bone fragment absorption should be assessed.

Effect of glenoid concavity loss on shoulder stability- a case report in a professional wrestler

“…Typically an anterior glenoid rim defect occurs either in form of attritional bone loss or a fracture with resulting free bony fragment. Such fragments typically medialize and resorb over time [2] and eventually either disappear or remain visible in form of a small ridge slightly medial to the anterior glenoid rim [3]. The size of the osseous defect is critical for shoulder stability and has been discussed in previous reports [4–6].…”

Traumatic Anterior Shoulder Instability: Part II. Bony Bankart – Small Versus Large Lesions

“…This means that at the time of fracture fi xation, the fragment could be considerably smaller than it was initially and therefore too small to succeed in regaining stability of the joint [ 24 ]. Nakagawa demonstrated that most bony fragments showed severe absorption within 1 year after the primary traumatic episode.…”

“…Nakagawa demonstrated that most bony fragments showed severe absorption within 1 year after the primary traumatic episode. They recommended that before arthroscopic Bankart repair, not only glenoid defects but also bone fragment resorption should be assessed [ 24 ]. Park et al reported that the fragment size decreased from that measured preoperatively to the size measured 3 months after surgery [ 27 ].…”

Glenohumerale Luxation

“…Verschiedene Autoren zeigen sehr gute und gute Resultate nach arthroskopischer Refixation im Kurzzeit-Follow-up [20][21][22][23]. Demgegenüber zeigen jedoch andere Autoren Resorptionen der Fragmente von bis zu 70% [24], was mit der Erfahrung der Autoren einhergeht und höhere Reluxationen zeigt. In unserer Serie von 6 Profisportlern (Handball und Eishockey) mit kleineren isolierten ossären Pfannenrandläsionen, zeigen die Bankart-Refixationen allesamt Reluxationen oder Restinstabilitäten im mittleren Follow-up, welche darauf mit einem Korakoidtransfer nach Latarjet erfolgreich behandelt werden konnten.…”
