Patella baja is most likely to occur after which of the following procedures? 1- scopic ACL recon w/cadaver allograft; 2-PCL recon using tibial inlay technique; 3- High tibial osteotomy; 4-MPFL recon w/semiT autograft
5- (TKA) |
high tibial osteotomies, especially opening wedge osteotomies. This procedure raises the tibiofemoral joint line and can cause retropatellar scarring and tendon contracture, decreasing the distance of the patellar tendon from the inferior joint line.Ans3

What is the primary func of the structure labeled w/ an asterisk in Fig A? 1-Prevents inf translation of the humerus w/ the arm by the side; 2-Provides IR of the humerus; 3-Prevents ant translation of the humerus w/ the arm in 45 deg of abd; 4-Prevents ant translation of the humerus w/ the arm in 90 deg of abd; 5-Provides supintion of the forearm & elbow flex
|
The primary function of the MGHL is to prevent anterior translation of the humeral head with the arm in 45-60 degrees of abduction.Ans3

Besides the biceps tendon, which of the following structures also pass through the rotator interval? 1- The coracohumeral lig only; 2-The coracohumeral and SGH lig; 3-The coracohumeral, SGH & MGH lig;
4-The SGH & MGH lig; 5-The SGH lig only |
ant border of the SS tendon from the superior border of the SC tendon, creating the triangular rotator interval, which is bridged by capsule. The coracohumeral and superior glenohumeral ligaments are considered to be structural contents of the rotator interval capsule, but each have separate origins and insertions.Ans2

|
Which of the following is considered the 1^ static restraint to ant gleno-hum translation w/ the arm in 90 deg of abd? 1-Shape of the bony articulation
2- (-) intra-articular pres; 3-SGH lig complex; 4. MGH lig complex; 5-IGH lig complex |
W/ arm @ 90 deg abd=ant band of the IGH lig complex is the primary static stabilizer to ant translation. (MGHL) resists anterior translation @ 45 deg of abd (SGHL) resists inferior translation w/the arm at one's side.Ans5

Hx:61yo laborer presents for TSA for primary OA. What is his chance of having a concomitant full-thickness SS tear? 1- <10%; 2-10 to 20%; 3-20 to 30%; 4-30 to 40%; 5- > 40%
|
Full-thickness supraspinatus tears have been historically rare in patients with primary shoulder osteoarthritis, with most studies showing a rate of < 10%, asymptomatic pts w/prevelance of rotator cuff tears (30-55%) in individuals over the age of 60.Ans1
|
|
In comparison to pts w/ OA, pt w/ inflammatory arthritis undergoing shoulder arthroplasty are more likely to have? 1-a large inf humeral osteophyte
2-medialization of the glenohumeral jnt line; 3- pos humeral head subluxation; 4-sclerotic glenoid; 5-pos glenoid wear |
Inflammatory arthritis (e.g. JRA, RA) of the shoulder characteristically demonstrates concentric glenoid erosion w/ medialization of the glenohumeral jnt. Subchondral sclerosis is seen in OA w/ periarticular osteopenia is seen in inflammatory arthritis. A large inferior humeral osteophyte is commonly seen in advanced shoulder OA.Ans2

Hx:72yo c/o progressive pain, restriction of motion in L shoulder. PE= active & passive motion are restricted to 90 deg of forward elevation & neutral external rotation. xray Fig A & PE, where is glenoid wear most likely to exist? 1-Anterior; 2-Posterior; 3-Superior; 4-Inferior
5. Central |
MC pattern of glenoid wear is central or posterior,
pts w/ posterior wear and subluxation, the posterior capsule becomes stretched, osteophytes form, and the anterior capsule and subscapularis shorten and contract->significant loss of ER, as is seen in this patient. An axillary XR or CT scan would be needed to assess the deg of pos glenoid wear, In addition, when considering TSA, pts w/< 40-45° of ER w/ exam under anesthesia should be considered for SC lengthening and anterior capsule release.Ans2 |
|
xray of (FAI), which of the following views is obtained with a standing xray at an angle of 65 deg from anterior between the pelvis and the film? 1- AP pelvis
2-Inlet; 3-Outlet; 4-Frog lateral; 5- False profile |
False profile view (also known as Faux profil) is performed with the patient standing with the affected hip on the cassette, the ipsilateral foot parallel to the cassette and the pelvis rotated 65° from the plane of the cassette. It can be used to assess anterior coverage fo the femoral head for patients with hip dysplasia (DDH) and FAI.Ans5
