Fractures of the femoral neck

7. INTRA CAPSULAR FRACTURE fracture neck femur
The femoral neck is the commonest site of fractures in the elderly.
Mostly occur in women between decades.

8. Risk factors

9. 1.Osteoporosis osteomalacia

12. 2.Diabetes

13. 3.Stroke

14. 4.Alcoholism

15. 5.Chronic debilitating disease .
6.Weak muscle and poor balance in old people. parkinsonism)

16. Mechanism of injure

17. In elderly Directly Fall on greater trochanter.
Indirectly. Less force with catching toes in carpet with external rotation of the lower limb.

18. In younger individual fall from height or car accident (more sever force).

19. Pathological anatomy and classification

20. The most useful is that of garden which is based on amount of displacement apparent in the pre-reduction x-ray of the neck femur.

22. Stage 1
impacted

23. Stage 2
complete fracture Undisplaced

24. Stage 3
complete with moderate displacement.

25. Stage 4
severely displaced fracture.

26. Fracture neck femur has poor capacity for healing

27. Why???

28. Tearing the capsule vessels.
Intra-articular bone has flimsy periostum
No contact with soft tissue.
Synovial fluid wash.

29. Clinically:
History of fallen on the ground.
Pain in the hip.

30. O\E
Limb lies laterally rotation and looks ,Short (displaced fracture).
In impacted patient might walk.

31. Radiological examination
two questions must be answered. Is there a fracture? Is it displaced ?

32. :Radiological classification
GRADE 1
:the femoral head is in its normal position or tilted into valgus and impacted on the femoral stump.

33. GRADE 2
The femoral head is normally placed and the fracture line may be difficult to diagnosed

34. GRADE 3
The femoral head tilted out of position and the trabecular marking are not in line with those of innominate bone.

35. GRADE 4
The femoral head trabeculae are normally aligned with those of innominate bone.

36. D.D: Stress fracture. Undisplaced fracture. Painless fracture.
Multiple fractures as with femoral fracture may have neck fracture and missed.

37. Treatment:
Surgery mandatory to overcome complications.

38. Initial treatment
1.General measure as pain killer.

39. 2.Temporary limb splintage ( skin traction).

40. Full investigation
Chest x ray
ECG.
F B S.
B urea.
Blood group
Blood preparation for
transfusion.

41. 3.Treatment depend on the type and age of the patient
YOUNGER.
Screw.

43. 4.DHS.

45. ELDERLY PEOPLE
5.Austen Moore.

46. 6.Total hip replacement.

47. Complications:
General

48. DVT

49. Pulmonary embolism.

50. Pneumonia.

51. Bed sore.

52. Local:
A.N. 30% in displaced fracture, 10% in Undisplaced fracture.

53. Non union
> 30% femoral fracture fails to unite particularly those with sever displacement. .

54. Osteoarthritis ,a vascular necrosis or femoral head collapse may lead after several years to secondary osteoarthritis.

55. Inter-trochanteric fractures (extracapsular fracture)
.It is extra capsular fracture occurs in elderly.
.Unite quite easily and seldom cause a vascular necrosis.

56. Mechanism of injury: Directly on trochanter.
Twisting force indirectly.

57. The crack runs up between the lesser and greater trochanter.

58. Pathological anatomy divided into:
Stable:

59. Unstable are those where
a. posteriomedial cortex is shattered.
b. poor contact between fracture segment.

61. Clinically: Old and unfit History of trauma .
Unable to stand with pain.

62. EXAMINATION
The leg is shorter and more externally rotated than intracapsular fracture.
Ecchymosis

63. Radiological examination
2 types
Stable.

64. Unstable.

65. Treatment:
Same previous principle almost always treated by early internal fixation.
(to overcome) the possible complications associated with prolonged recumbency.
To get the patient up and walking as soon as possible.

66. 1.Sliding nail

67. 2.L-plate

68. 3.External fixation

69. Gamma nail

70. PHYSIOTHERAPY
Postoperative exercise is started as early as possible on the
( day after operation ).
Patient is allowed up and partial weight bearing as soon as possible.

72. Complications:
Early:
general complications.

73. Late:
1.failed fixation.
2.malunion.
3.rarely nonunion.

74. HIP DISLOCATION

75. anatomy

76. Injuries of the hip and femur

77. The magnitude of force needed to dislocate the hip joint particularly well-contained by virtue of its bony and soft-tissue anatomy.
is so great that the dislocation is often associated with fractures - either around the joint or elsewhere in the same limb.

78. of the femoral head displacement:
Hip dislocations are classified according to
the direction
of the femoral head displacement:

79. Traumatic Dislocations of the hip.
Posterior.
Anterior.
Central.

80. Posterior dislocation:
Mechanism of injure:
4 out of 5 traumatic hip dislocations are posterior.

81. Usually occur in road traffic accident when the knee striking the dashboard

82. the femoral head is forced out of its socket sometimes associated with fracture.

83. Clinically: In a straight forward case the diagnosis is easy. O\E
Leg is short, internally rotated, adducted ,
and slightly flexed hip.

85. Some times fracture femur associated with, and clinically missed.

86. Sciatic nerve examination distally is important.

87. The golden role is to x ray the pelvis in every case of sever injure
and with femoral fracture to include both the hip and knee.

88. Radiological examinations
X-R AP view we can see the dislocation with or without associated fracture posterior wall of the acetabulum,
or fracture head of the femur,
And neck of femur.

91. CT scan
is the best way of demonstrating acetabuluar fracture or any bony fragment.

92. Treatment:
The dislocation must be reduced as soon as possible under general anesthesia. In the vast majority of cases this is done with closed reduction

93. U\A on the ground. Pelvic support. In line of the lower limb traction.
Then gradually flexion of the patients hip and knee in 90 degree.

94. At 90 hip flexion traction is increased and some times little rotation is increased (both internal and external) to accomplish reduction.
Satisfying clunk terminate the procedure.

96. Skin traction 3-6 weeks.

97. Physiotherapy during and after that.

98. In complicated dislocation
(surgery
is indicated) .

99. Complications:
Early.
Sciatic nerve injures when there is fracture lead to foot drop in 10%.
So nerve function must be tested and documented before reduction.

100. Vascular injure
mainly for the superior gluteal artery.

101. Associated fractured femoral shaft.
So as a rule the buttock and the greater trochanter should be palpated.

102. Late: A vascular necrosis By x ray appeared between 6weeks- 2 years.
It occur in 10% and raised to 40% if neglected more than 12 hours

103. Myositis ossificans.

104. Osteoarthritis due to fracture acetabulum or femoral head, or a vascular necrosis

105. Traumatic anterior hip dislocation:
Mechanism :
Road traffic accident ,miner, building laborer who is leg wide .
knees straight .
Back bent forward.

106. Clinically: O\E Leg external rotation. Abducted and slightly flexed.
Bulging head seen laterally and also feel.
Hip movement impossible.
Neurovascular examination necessary.

107. Radiological examination:
Hip dislocated either superior, inferior in relation to the acetabulum.

108. Treatment: Same principle as posterior
While traction of the leg keeping adducted till reduced.

109. Central fracture -dislocation
