Q

Hip Fractures

A

Affected leg is shortened and externally rotated.

Specific treatment depends on specific location as shown by xrays.

26
Q

Femoral neck fractures

A

Faster healing and earlier mobilization can be achieved by replacing the femoral head with a prosthesis.

27
Q

Intertrochanteric Fractures

A

Open reduction and internal fixation.

Immobilization will pose high risk for deep venous thrombosis and pulmonary emboli.

28
Q

Femoral Shaft Fractures

A

Intramedullary rod fixation.
Can cause shock if bilateral and communicated.
If open, OR emergency- must be cleaned and closed within 6 hours.

29
Q

Knee Injuries

A

MRI is best highly recommended technological way of looking at knee.

30
Q

Collateral Ligament Injuries

A

Isolated injuries are treated with hinged cast.

If several ligaments are torn, surgical repair is preferred.

31
Q

Anterior Cruciate Ligament Injuries

A

MRI is diagnostic. Athletes require surgical reconstruction.

32
Q

Meniscal Tears

A

Repair is done trying to save as much meniscus as possible.

33
Q

Tibial Stress Fractures

A

Seen in young men subjected to forced marches.

Tx with cast and repeat xrays 2 weeks. Non-weight bearing (crutches) is another options.

34
Q

Leg Fractures Involving Tibia and Fibula

A

Often seen when pedestrian is hit by car.
If cannot realign for closed reduction, then intramedullary nailing is needed.
Lower leg is one of most common sites for compartment syndrome.

35
Q

Rupture of Achilles Tendon

A

Out of shape middle-aged men who subject themselves to to severe strain. Loud popping noise is heard and they fall clutching ankle.

Limited plantar flexion is still possible. Palpation will reveal a gap. Surgery will provide quicker care.

36
Q

Fractures of the Ankle

A

AP, lateral, and mortise xrays are diagnostic.

Open reduction and internal fixation is needed.

37
Q

Compartment Syndrome

A

Forearm or lower leg. Excruciating pain with passive extension.
Tx: emergency fasciotomy is required for treatment.

38
Q

Pain under Cast

A

Always handled by removing cast and examining limb.

39
Q

Open Fractures

A

Broken bone sticking out through a wound.

Require cleaning in OR and suitable reduction within 6 hours from time of injury.

40
Q

Posterior Dislocation of Hip

A

Femur is driven backwards. Leg is shortened, adducted, and internally rotated. Because of tenous supply of femoral head, OR emergency to avoid avascular necrosis.

41
Q

Gas Gangrene

A

Deep, penetrating dirty wounds. Site is tender, swollen, discolored and has gas crepitation.
Tx: Copious IV penicillin, extensive emergency surgical debridement and hyperbaric oxygen.

42
Q

Radial Nerve Injury

A

Injured when oblique fractures of middle to distal thirds of the humerus.
No dorsiflexion.
Fracture is reduced and arm is placed in cast.

43
Q

Popliteal Artery Injuries

A

Posterior dislocation of knee.
Attention to integrity of pulses, doppler studies, or CT angio.
Prompt reduction to minimize vascular compromise.

44
Q

Facial fractures and closed head injuries

A

Always prompt evaluation of cervical spine.

45
Q

Carpal Tunnel Syndrome

A

Initial treatment is splints and antiinflammatory agents.

If surgery is needed, electromyography should precede it. (Electro-diagnostic studies of nerve conduction).

46
Q

Trigger Finger

A

Finger acutely flexed and unable to extend unless pull it with other hand. When they do so, painful snap.
Tx: Steroid injection is first line. Surgery is treatment of last resort.

47
Q

De Quarvain Tenosynovitis

A

B/c of hand into wrist flexion and thumb extension.
Pain along radial side of wrist and first dorsal compartment.
Pain reproduce by asking her to hold thumb inside closed fist with ulnar deviation.
Splint, antiinflammatory agents, and steroid injection.

48
Q

Dupuytren Contracture

A

Older men of Norwegian ancestry.
Contracture of palm of hand and palmar fascial nodules.
Surgery may be needed if hand cannot be placed flat on a table.

49
Q

Felon

A

Abscess in pulp of a fingertip, caused by neglected penetrating injury.
Pressure can build up and lead to tissue necrosis; thus surgical drainage must be urgently done.

50
Q

Gamekeeper Thumb

A

Injury of ulnar collateral ligament sustained by forced hyperextension of the thumb.
Casting otherwise dysfunctional, painful, and arthritis.

51
Q

Jersey Finger

A

Injury to flexor tendon when flexed finger is forcefully extended.
When making a fist, distal phalanx of injured finger does not flex with others.

A

Extended finger forcefully flexed. Extensor tendon is ruptured.
Tip remains flexed when rest are extended.
Splinting usually first line tx.

53
Q

Traumatically Amputated Digits

A

Surgically reattach when possible.
Amputated digit should be cleaned with sterile saline, wrapped in saline moistened gauze, placed in sealed plastic bag, and rested on top of ice. Should not be allowed to freeze.

54
Q

Lumbar Disk Herniation

A

Occurs almost exclusively at L4-L5 or L5-S1. Peak age incidence is 45-46.
Vague aching pain before sudden onset neurogenic pain precipitated by event like attempting to lift object.
Tx: Body will reabsorb extruded disc. Require 3 week of bed rest.
Surgery if neurologic deficits are progressing and emergency intervention required if cauda equina syndrome.

55
Q

Cauda Equina Syndrome

A

Distended bladder, flaccid rectal sphincter, perineal saddle anesthesia.
Surgery for immediate decompression.

56

Weight loss is also additional finding. MRI is best diagnostic tool.

Q

Diabetic Ulcers

A

Start because of neuropathy and fail to heal because of microvascular disease.

Q

Marjolin Ulcer

A

SCC of skin developing in chronic leg ulcer.

Tx: Wide local excision and skin grafting are done.
