Surgical Specialties -: Questions With Detailed
Solutions
Orthopedic surgery treats the following conditions: Right Ans -
°Degenerative diseases
°Tumors
°Sports injuries
°Congenital disorders
°Trauma
±Minimally invasive
±Faster recovery
±Good for debridement
±Helps with diagnosis Right Ans - arthroscopy
±Open procedure
±Joint is replaced, remodeled or realigned
±Relieves pain in the joint
±Restores function of the joint Right Ans - arthroplasty
___ is one of the most widely performed orthopedic surgeries Right Ans -
Knee arthroscopy
Risks Following Orthopedic Surgeries Right Ans - ±Bleeding
±Infection
±Clotting
±Damage to nerves or spinal cord
±Persistent pain
Postoperative Treatment for Orthopedic Surgeries Right Ans - ±Restore
movement:
°Physical therapy
°Massage therapy
°Exercises
±Pain management
±Prevent injury
,±Prevent infection
±DVT/ PE prophylaxis
DVT/ PE prophylaxis post ortho surgery = Right Ans - Enoxaparin OR
warfarin OR aspirin
-- VARIABLE as per surgeon preference (generally 4-6 weeks)
classification for hip fx Right Ans - Garden classification
I - nondisplaced - valgus impacted incomplete fx, medial cortex preserved
II - nondisplaced - complete fx
III - displaced - complete fx & partial displacement
IV - displaced - complete fx & complete displacement
Dx hip fx Right Ans - °Plain films
°MRI if needed
Tx if Femoral neck, nondisplaced/valgus impacted Right Ans - Internal
fixation with 3 cannulated screws
Tx if Displaced femoral neck: <65 yr old Right Ans - Urgent anatomic
reduction, cannulated screws or dynamic hip screw (DHS)
Tx if Displaced femoral neck >65 yr old Right Ans - Total hip arthroplasty
for healthy, active patients and hemiarthroplasty for frail or sick patients
Tx if Intertrochanteric fractures Right Ans - Intramedullary nail (IMN) or
dynamic hip screw (DHS)
Tx if Unstable intertrochanteric/reverse obliquity Right Ans - IMN, blade
plate, dynamic condylar screw (not DHS)
hip replacement indications Right Ans - OA
RA
, fractures
cancer
joint instability
congenital hip disorder
hip replacement relative contraindications Right Ans - Recent infection
pain is not severe
<60 yoa with alternative surgery available
total vs hemi hip replacements Right Ans - Total: Replaces BOTH
acetabulum and femoral head
Hemi: Replaces ONLY the femoral head
hip implants for replacement must produce ___ friction movement Right
Ans - low
parts of the hip implant Right Ans - °Acetabular cup
°Femoral component
°Articular interface
types of hip implants Right Ans - °Ceramic
°Metal on metal
°Cemented
cemented vs uncemented fixation Right Ans - Cemented fixation: Cement
stem uses acrylic bone cement between the stem and bone
Uncemented fixation: Uncemented stem uses friction, shape and surface
coating to stimulate bone remodeling
hip replacement approaches Right Ans - °Posterior
°Lateral
°Anterolateral
°Anterior
why should pts avoid acute hip flexion and/or adduction immediately postop
Right Ans - Can lead to subluxation or dislocation of hip
-- shortened extremity, increased discomfort, inability to move
