teen boy injured hip competing in a track meet. xray in Fig. Which muscles is most likely injured? 1-Tensor fascia lata; 2-Gluteus medius; 3-Gluteus minimus; 4-Rectus femoris; 5-Biceps femoris
|
Adolescent athletes may sustain an avulsion of the anterior inferior iliac spine (AIIS) which is due to the pull of the rectus femoris,Ans4

68yo F R-hand dom c/o R shoulder injury Fig, denies shoulder pain prior to a fall @ work after slipping on some water 4 wks ago, smokes 1/2 ppd. Which characteristics of this pt confer the >est risk of not healing p/surgical repair? 1-1/2 ppd smoking; 2-Surgical repair 4 wks p/injury 3-Worker's comp case; 4-68 yrs of age; 5- R-hand dom
|
Pt age older> 65 is the highest risk factor for nonhealing of the surgically repaired rotator cuff, Advanced fatty infiltration & mus atrophy on MRI & sign glenohumeral DJD are relative contraindications for rotator cuff repair.Ans4
|
|
Which of the statements re: RCR is true? 1-Bone anchor drilling enhances vascularity p/RCR; 2-Shoulder motion p/ RCR should be restricted to enhance blood flow to repair site; 3-Doub row RCR >clinical results when compared to sing row repairs; 4-Subacr decomp > rates of succ RCR; 5-Failure to heal the RCT-> bone consistently results in poor pt outcomes
|
Suture anchor drilling into hum head has been shown to > vascularity response during RCR, peribursal tissue and bone anchor site were the main conduits of blood flow for the rotator cuff tendon. Blood flow of repaired RCT < w/time, but exercise significantly enhanced blood flow to the repaired RCT.Ans1

The RCT in an overhead throwing athlete is most susceptible to tensile failure due to eccentric loading during which of the phases of throwing Fig? 1-A; 2-B; 3- C; 4-D; 5-E
|
deceleration phs of throwing in the overhead athlete, the RCT is the principle decelerator of the arm, is susceptible to tensile failure due to eccentric loading during this phase.Ans5
|
|
Which pt has the best indication for latissimus dorsi transfer? 1-55yo M w/ RCT arthropathy & prox hum migration; 2-85yo M w/ irreparable posterosuperior RCT & 60 deg forwd elevtn & 0 deg-active ER @ his side; 3-45yo M w/ complete irreparable supraspinatus & subscapularis tears w/ 90 deg-active forwd elevtn
4-50yo M w/large irreparable posterosuperior RCT w/100 deg-forwd elevtn & -10 deg-ER; 5-35yo w/ an acute traumatic complete posterosuperior RCT w/ 0 deg-active ER |
younger adult pt w/ an irreparable posterosuperior RCT, lack of advanced glenohumeral DJD, has an intact subscapularis function to stabilize the hum head after latissimus transfer, and who maintains some active forwrd elev.Ans4

What is the avg med-to-lat dist of the supraspinatus tendon inser @ its ftprint on the grtr tuberty? 1-6-8mm; 2-14-16mm; 3-20-22mm; 4-24-26mm;5-30-32mm
|
cadaveric have shown the avg med-to-lat dist of the supraspinatus tendon footprint on the grtr tuberity is 14-16mm/1.4-1.6 cm, measured 14.7mm, Large RCT=3-5 cm or 30-50 mm Massive > 5 cm or 50mmAns2

During diag scopic eval of a pt's shoulder, you ID a thickened portion of the coracohumeral lig, near its avascular zone, runng perpendicular to the supraspinatous tendn. it is in Fig w/black arrows. What is the name for this structure? 1-Mid glenohumeral lig;
2-Rotator interval; 3-Coracoid process; 4-Rotator cable 5-Rotator crescent |
black arrows ID the rotator cable, while the asterix identifies the rotator cresent. rotator crescent & rotator cable =2 anatomic structures closely assoc w/RCT that form the shoulder's "suspension bridge." The crescent is bounded at its proximal margin by a thick bundle of fibers called the rotator cable, and thickened portion of supraspinatus.Ans4

|
latissimus dorsi tendn transfer is for tx of massive irreparable posterosuperior RCT. All have been shown to result in worse clinical outcomes p/transfer EXCEPT?1-Nonsynergistic action of the transferred mus; 2-Fatty atrophy of the supraspnts & infraspnts; 3-Deficien of the subscplrs; 4-Absence CA lig; 5-Deltoid weakness
|
Absence of the CA lig may allow anterosuperior escape in RC deficient shoulders BUT has NOT been shown to lead to worse outcomes p/tendon transfer, pts w/ deficiency of the deltoid/subscapularis, nonsynergistic mus action p/transfer, or fatty infiltration of the posterosuperior cuff have worse clinical outcomes.Ans4
|
|
Which of the following may be seen during scopy in a pt w/subscapularis tear? 1-Uncovered lesser tub; 2-Retraction subscapularis tendn to the level of the glenoid; 3-Avulsed superior glenohumeral lig; 4-Med biceps subluxation; 5-All of the above
|
superior glenohumeral ligament(SGHL)/coracohumeral ligament(CHL) complex may show a partial tear which has been called the "comma sign", All of the findings mentioned may be encountered.Ans 5

20yo footbll player is injured, tx regimen includes immobilization of the knee in 120 deg flex. What injury has this pt most likely sustained? 1-iliac crest contsion; 2-Avulsion fx of the lesser trochanter; 3-Quadriceps contsion; 4-Hamstring rup; 5-Sports Hernia
|
Surveillance for comprtmnt synd =needed acutely & chronic manifes= myositis ossificans, Iliac crest contusions or “hip pointers” occur after direct trauma & benefit from placing the affected leg in extnsn. Athletic pubalgia or “sports hernia” is an injury to the mus of the abd wall or add longus that prod ant pelvis & groin pain in absence of a true inguinal hernia.Ans3

34yo M playing rugby 2 wks ago when an opposing player fell on the lat aspect of his L knee, felt an immediate pop & was unable to bear wt on the extremity initially, has had recurrent popping & catching in the knee since the initial injury & intermittent numb on the top of ft. xray,MRI Fig, What is the next step in management?

1-scopy for repair or debrid of men tear; 2-Reconst of ACL; 3-scopy for repair/debrid of femoral condyle OCD
4-CR of dislocation; 5-(EMG) for evaluation of ant tarsal tunnel synd::: CR is done by placing an appr directed force to the fibular head with the knee flexed between 80° - 110°, which relaxes the LCL & biceps fem tendn, Open red is indic for the acute dislocn that is NOT successful CR, continued instability, surg tx=arthrodesis, fib head resec, proxtibiofibular jt capsule recon.Ans4 |
