Introduction
• Ipsilateral fractures of the femoral neck and shaft are rare
• In high-energy injuries, especially in road traffic accidents
• The incidence ranges : 1% to 6% of the femoral shaft fractures

Discussion
• Young and male dominated
• The incidence ranges from 1% to 6% of the femoral shaft fractures Wolinski PR (Clin Orthop, 1995)

Discussion
• Femoral neck fractures are commonly missed initially; the rate varies from 19% to 31%
• The reported incidence of AVN in ipsilateral femoral neck and shaft fratures (3%)

Discussion
• Mean age: 38 years
• Incidence : 21 / 1113 (1.9%)
• Missed neck Fx. : 6 / 21 (29%)
• AVN : 1 / 21 (4.7%)

Discussion
• Lower than the solitary femoral neck fracture(10%)
Because 1. The force is dissipated in the shaft fracture 2. Base of neck fracture and non-displaced
neck fracture Gerber C. (Clin Orthop Rel Res. 1993)
<Incidence of AVN>

Discussion • Early fixation & ambulation : morbidity ↓
• Suggested immediate reduction & fixation
: avoid displacement of the neck fracture and AVN
• Delay of weeks in the fixation does not increase the complication rate

Discussion
• The neck fracture were stabilized first : avoid further displacement of the neck fracture and AVN
• The shaft fractures were stabilized first → no further displacement of neck fracture

Discussion
• In our cases, the shaft fractures were stabilized first, and the neck fractures treated later
• Use Fx. table : for exact reduction
→ no further displacement of neck fracture

Discussion
• Cancellous lag screws or DHS (neck) compression plate (shaft) : 15 cases
VS• Intramedullary nailing : 12 cases
→ Both achieved satisfactory functional outcome Singh R. (J Orthop Traumatol. 2008)

Discussion
• Both hip AP X-ray checked: 18/21 cases
- 3 of 18 (16.7%): missed diagnosis
• No evaluation of hip (femur neck) : 3 cases
→ Pre or intra Op C-arm manipulation
<In our study>

Discussion
• Abdominopelvic CT or pelvis 3D CT checked
- 6 cases : detecting a fracture
→ CT reading : careful attention
<In our study>

Conclusion• Can be missed during the initial diagnosis in high-energy injuries
• Demands careful attention - Adding AP x-rays of the hip joint - Hip CT - Bone scan - Pre Op C-arm manipulation - Follow up x-rays
