Arthrex Arthroplasty 2024 exam study guide questions and answers(100% accurate)

Subscapularis Tenotomy - most common technique used in a TSA procedure. - Easy to suture - has poor blood supply - can often heal as scar tissue. Subscapularis Peel-Off - least common technique used in a TSA procedure. - repairs back through transosmosis bone tunnels. - bone to tendon healing can be unpredictable - allows surgeon to medialize the tendon.

Incision is made from the clavicle to the humeral head 2) Superolateral Approach (uncommon) . UNIVERS II humeral head sizes - range from 40 to 56 going up in increments of 2. - Sizes: 40/17, 42/17, 44/17, 44/19, 46/18, 46/20, 48/19, 48/21, 50/19, 50/21, 52/20, 52/22, 54/21, 54/23, 56/22, 56/24 version of humerus - measured from 0-10 degrees. heads of humeral implant - Made of cobalt chrome (nickel is used in the preparation of these implants)(NOT recommended for patients with a true nickel allergy) Neck/shaft of humeral stem implant - ranges from 125-140 degrees of shaft inclination - variable after implantation - matching humeral head osteotomy - +/-10degrees version - 3.5mm offset - stems are made of titanium -newer version of the stems is far easier for removal because of the new trunion and box geometry. Humeral Prep Tray . Humeral Gold Trials (5-13mm) . resection protectors 40-45mm . trial trunion . humeral head trials (blues=anatomic)(black=thicker) . HEX Driver . head driver . head impactor . trunion impactor . torque indicating HEX Driver . pointed impactor . 2 head protectors . head extractor . extraction block . trunion extractor . slotted mallet Humeral Bone Prep Tray (UNIVERS II) TOP TRAY - Top layer mainly for humeral resection . left and right humeral resection guides; sit at 132.5 degrees and come in both small and large sizes. - humeral resection block (primed along anatomic neck of humerus to resect bone) - Quick connect T-handle - Version Rods (used in conjunction with the broaches) - Right and Left Humeral Resection Templates (designed to estimate what the humeral neck angle is) - Broach Alignment guide - Humeral Reamers (sizes 5,6,7) BOTTOM TRAY - Slap Hammer (used in revisions in conjunction with the resection block) (can be used in the UNIVERS II or APEX) - Broaches (Sizes are 5-13mm (sizes go up in incriminates of 1mm)) UNIVERS APEX Instrument Set - Reamers= 6 and 7mm - Broach Allignment guide - Humeral Trials (6 goes up in 1mm increments all the way to 15) unlike the UNIVERS II that stops at 13mm. BASE LEVEL Broaches (6mm-15mm goes up in increments of 1mm) UNIVERS VaultLock Glenoid Instrument Set ** Newest tray in the UNIVERS System - 2.8mm pin - Small, Medium, Large, Extra Large Glenoid sizers - 2 glove protectors ' - small, medium large, extra large reamer (VaultLock style reamers all have a yellow band around reamer shaft just indicates that its a VaultLock reamer) - 6mm Canulated Drill - Translucent Provisionals - drill guides that are specific to the VaultLock implant - graft compaction tool (used to pack the bone slurry or bone graft into the flutes of the central peg feature of the VaultLock)
