INTRODUCTION
• Femoral neck fractures are rare conditions in children.
• Most of the fractures result from high-energy trauma.
• Complications are associated with serious long-term morbidities.

INTRODUCTION
“ Hip fractures in children are of interest because of the frequency of complications rather than the frequency of fractures.”[1] - CANALE

AIMS/OBJECTIVES
• The aim was to evaluate the pattern of presentation, clinical outcome and complications associated with the management of paediatric femoral neck fractures at NOH, Dala-Kano.
![Page 6: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/6.jpg)
PATIENTS AND METHOD
• The study reviewed the clinical records of paediatric patients presenting with femoral neck fractures or its complication managed at the NOH, Dala-Kano, between May 2008 and June 2012.
• Inclusion criteria:- Age ˂ 16 years at the time of injury- Complete radiographic records

PATIENTS AND METHOD• Eight patients were managed but only five met
criteria for analysis .• Delbet classification was used.• All patients had operative treatment with either
cannulated screws alone or primary osteotomy stabilized with paediatric osteotomy plate.
• Ratliff criteria was used for outcome analysis in 4 of the 5 patients, who had completed 1 year follow-up.

DISCUSSION
• Paediatric femoral neck fractures are uncommon.
• The average incidence, worldwide is ˂ 1% of all paediatric fractures [1,2,3,4,5].- May be higher in our environment [6].
• Most cases result from high-energy trauma.
![Page 17: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/17.jpg)
DISCUSSION
• The presence of physis and vascular peculiarities make paediatric femoral neck fractures an important clinical entity.
• The risk of severe complications like AVN and growth arrest, make prompt treatment of paediatric femoral neck fractures a priority.
![Page 18: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/18.jpg)
DISCUSSION
• Delbet classified these fractures into 4 types- Type I : Transepiphyseal (5-10%)- Type II : Transcervical (50%)- Type III : Cervico-trochanteric or Basal (35%)- Type IV : Intertrochanteric (10-15%)
• Our study revealed more of type III (3 patients).
![Page 19: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/19.jpg)
DISCUSSION
• Three of our patients, presented late with complications – malunion, nonunion and coxa vara.
• Initial TBS involvement in 3 patients - Remaining 2 cases were referrals
• We offered 4 of our patients primary osteotomy due to the mode of presentation.
![Page 20: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/20.jpg)
DISCUSSION• Of all the complications reported in the
literature, AVN is the most common and most devastating [7,8].
• Quick et al [9], reported an average incidence of 6-53% for AVN in paediatric femoral neck fractures.
• In our study, AVN occurred in 1 patient, and risk factors identified include:- Type of fracture and displacement- Late presentation.
![Page 21: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/21.jpg)
DISCUSSION
• A case of premature physeal closure occurred, with worsening LLD at follow-up.
• Residual coxa vara also seen in 2 patients.• Other complication seen was surgical site
infection in 1 patient.

DISCUSSION• Ratliff criteria:
![Page 23: Management of femoral neck fractures in children](https://reader038.fdocuments.in/reader038/viewer/2022102616/556b8a5fd8b42a6c7c8b51a6/html5/thumbnails/23.jpg)
CONCLUSION
• The clinical outcome of our study was mainly influenced by late presentation.
• Malunion, Nonunion and coxa vara were seen as primary complications rather than secondary.
• Based on Ratliff criteria, at the end of 1 year, 2 of our patients had satisfactory outcome.
