Fractures of the neck of femur in children: an experience at the Aseer Central Hospital, Abha, Saudi Arabia
Introduction
Fracture of the neck of femur in normal children is rare but is known to be associated with a high rate of complications, especially femoral head necrosis [1], [2], [3]. When it occurs, it is usually due to severe high-velocity trauma [3], or a pathological process affecting the bone [1], [4], [5], [6], [7]. Hamilton [8] believes that most orthopaedic surgeons will see only a few of this type of fracture in children in their entire professional career. Various reports confirm the rarity of this condition [9], [10], [11]. Cheng and Tang [9] in a retrospective study over a 10-year period reported only 14 cases of fractures of the neck of femur in patients under 16 years of age. Sferopoulos and Papavasiliou [10] reported 20 cases of intracapsular fractures of the femur in children below 14 years of age. In a retrospective study between 1926 and 1988 from the University of Iowa, Davison and Weinstein [11] reported 26 cases of hip fractures in children between the age of 1–16 years.
Many authors stress the fact that the importance of this condition is not because of the frequency of its occurrence but because of the frequency and life-long disability resulting from complications [2], [3], [4], [8], [11].
The aims of this report were to review all the cases of fractures of the neck of femur in children, seen at the Aseer Central Hospital, Abha since the establishment of the orthopaedic unit in 1992 until 1999 and to share our experiences in the management of this important condition and to provide a reference point for future study of this pathology in this region.

Patients and methods
Aseer Central Hospital is the tertiary referral centre for Aseer region of Saudi Arabia. Almost all the fractures of femoral neck in children are referred to Aseer Central Hospital for management. The Aseer region (population 1,200,000) is located in the southwest of Saudi Arabia covering an area of more than 80,000 km2. The region lies a few kilometres away from the northern border of the neighbouring Yemen [12].
This is a retrospective study of fractures of the neck of femur in children below
Results
Fourteen children presented with 14 femoral neck fractures over the 8-year period of the study. Femoral neck fractures constituted only 0.3% of all the fractures treated in children during this period and 0.6% of femoral neck and intertrochanteric fracture. Five femoral neck fractures (35.7%) occurred on the right side and nine (64.3%) on the left side. The mean age was 9.1±3.8 years (range 4–16 years). There were six males and eight females. (male:female ratio was 1:1.3). Eight cases (57.1%)
Management and outcomes
All six patients (42.9%) with Delbet type II fractures were treated by closed reduction and internal fixation (Fig. 1a and b). All of them developed avascular necrosis (AVN) of the femoral head (Fig. 2). In this group, three were of Ratliff type-I AVN [14] involving the whole femoral head with subsequent collapse of the head. The other three were Ratliff type-II AVN [14] involving only a part of the head of femur (Fig. 3). These three cases improved without collapse of the femoral head.

Discussion
Fractures of the neck of femur are rare [1], [2], [3], [4], [5], [6], [7], [8], [14]. They account for <1% of all paediatric fractures [14] and the prevalence is <1% of those seen in adults [1], [2], [3]. In this series, femoral neck fractures in children accounted for 0.3% of all pediatric fractures and 0.6% of those of adults, thus confirming the rarity of these fractures in general and in the Aseer region of Saudi Arabia in particular. The aetiological factors of femoral neck fracture in
