What is the MC complication following surgical fix for the fx Fig A in an 8yo B? 1-Coxa valga; 2- Chondrolysis; 3-Stiffness; 4-Clinically significant limb length discrepancy; 5-Avascular necrosis

pediatric basicervical fem neck fx. Femoral neck fx in the ped pop have high rate of osteonecrosis. They are divided: epiphyseal, transcervical, basicervical and intertrochanteric. Fracture displacement, age over ten years and an epiphyseal or transcervical fracture pattern are risk factors for AVN. AVN rates were as follows: Delbet type I=38%, II=28%, III=18%, and IV=5%, where I=Epiphyseal, II=Transcervical, III=Basicervical, IV=IT.Ans5

Hx: 7yo presents w/ a fx of L supracondylar humerus & distal radius Fig A. PE= neurovascularly intact, skin shows no evidence of open wounds. xrays of the elbow = displaced supracondylar fx, wrist =extra-articular distal radius fx w/ 25 deg of dorsal angulation. This injury is tx'd w/ which of the following? 1-CR & casting of the supracondylar hum fx & distal radius fx; 2-CRPP both the supracondylar hum fx & distal radius fx; 3- CR& casting of the supracondylar hum fx & pinning of distal radius fx; 4-ORP both the supracondylar hum & the distal radius fx; 5-CRP the supracondylar hum fx & CR & casting of distal radius fx
|
clinical presentation = "floating elbow" w/ displaced fx of both the elbow and and wrist. The most appropriate tx is prompt CRPP both the supracondylar humerus fx & distal radius fx to prevent the occurrence of compartment syndrome prompted by casting.Ans2

Hx;7yo falls off the playground and sustains the injury fig A. What motor deficit is associated with the neurologic injury MC to this fx pattern? 1-Weakness of the FDP to the index finger; 2-Weakness of theEPL; 3-Wrist drop; 4-Weakness of the FPL; 5-Hand intrinsic weakness
|
flexion type supracondylar humerus (SCH) fracture, in which the distal fragment is displaced anteriorly. In these fracture patterns, the ulnar nerve is the most likely to be injured, specifically by the sharp spike of the proximal fragment, Ulnar nerve palsy would cause hand intrinsic weakness and clawing, Weakness of the flexor digitorum profundis to the index finger and flexor pollicis longus would be associated with AIN palsy. Wrist drop would be associated with radial nerve palsy. Weakness of extensor pollicis longus correlates with posterior interosseous nerve palsy.Ans5

The MC nerve injured in the fx shown in Fi A innervates all of the following muscles EXCEPT? 1-FDP index finger; 2- FDP middle finger; 3-FPL; 4-EPL; 5- pronator quadratus
|
(AIN) is the MC nerve injured with extension type pediatric supracondylar fx, AIN, a branch of the median nerve, is principally a motor nerve and innervates the Flexor Digitorum Profundus Index, Flexor Digitorum Profundus Middle, Flexor Pollicis Longus and Pronator Quadratus. It DOES NOT innervate the Extensor Pollicis Longus, which is innervated by the PIN. LOAF" for Lumbricals 1 & 2, Opponens pollicis, Abductor pollicis brevis and Flexor pollicis brevis.Ans4

Hx:28-yo African-American M w/ a hx of Sickle Cell Disease c/o progressive L hip pain x 2 yrs, denies any causative injuries. Fig A & B. Which of the following mechanisms is responsible for his sx? 1- Blood disorder due to abn hemoglobin S alleles
2-Progressive slippage of physis though the hypertrophic zone; 3-Osteo most likely due to Salmonella species; 4-Accumulation of glycosaminoglycan breakdown products 5-COL5A1 or COL5A2 mutation |
L hip osteonecrosis as a result of coagulation and vascular occlusion caused by sickle cell anemia, characterized by 2 abn hemoglobin S alleles. Under low oxygen conditions the affected blood cells become "sickle shaped" and unable to pass through vessels. This results in vascular occlusion that may have a variety of clinical consequences depending on the body part affected, Ans2: Progr slippage of physis though the hypertrophic zone describes SCFE; Ans3: osteonecrosis of the femoral head. There is an i> incidence of Salmonella osteomyelitis in pt w/ SCD, but Staphyl A is still the MC organism, An4: Accumulation of glycosaminoglycan breakdown products describes lysosomal disorders, Ans5: COL5A1 or COL5A2 mutation describes the mutation of Ehlers Danlos syndrome.Ans1

Hx: 9yo B sustains an injury to his R shoulder during a skateboarding fall. c/o pain and deformity. No deficits are present on neurovascular exam. Shoulder xrays Fig A. Which of the following is treatment? 1-Immobilization in a sling and follow-up xrays; 2-CRPP; 3-CR & spanning ex-fix; 4-CR & IM fixation;5-ORIF w/a plate construct

Salter-Harris II proximal humerus physeal fracture. 80% of the longitudinal growth of the humerus occurs through the proximal humerus allowing tremendous remodeling potential. The vast majority of these fractures can be treated non-operatively. A moderate reduction often occurs with simply positioning the patient upright and allowing gravity traction. Surgical indications include open fracture, neurovascular injury, and severely displaced fractures in a patient approaching skeletal maturity.Ans1
