Abstract

Breech foetuses are commonly delivered via caesarean section to prevent trauma and decrease the risk of head entrapment, though extraction by abdominal route can very rarely lead to traumatic femur fracture. Typical site of fracture is femoral diaphysis. Although femur fracture is a relatively rare complication, it represents one of the most common fractures of the lower extremity presenting in newborns. A 3900 g female child born at 39 weeks of gestation by caesarean section, presented swelling and tenderness of the left lower extremity in the second day of life. There was no apparent bone disorder predisposing to femur fracture. Fracture of left diaphysis was successfully treated by immobilization with Pavlik harness, healing in a good position for 23 days. Three months after birth, radiogram revealed regular bone consolidation and fracture fully welded. One year after birth, both lower limbs showed a proper mobility with no dysmetria. Caesarean delivery reduces increasingly traumatic complications, especially in breech delivery compared with vaginal delivery, but does not eliminate possible accidental injuries of the newborn. Predisposing factors are many, especially breech presentation and foetuses with malpresentation. Clinicians must be aware that abdominal delivery does not preclude the occurrence of femur fractures.

1. Introduction

Birth injuries presenting during the childbirth process are very rare, occurring in less than 1% of all live births [1, 2] and they are commonly associated with breech presentations and difficult deliveries [3, 4]. Three quarters of all birth-associated fractures of long bones are ascribed to vaginal breech deliveries [5]. Other risk factors include low birth weight and large foetuses [6]. Cesarean section has been reported to reduce almost completely the incidence of birth-associated injuries7 in new-borns with a variety of health complications [8, 9]. New-borns for whom are diagnosed with a fracture in the first week of life, in the absence of known post-natal trauma, are considered to have suffered a birth fracture, as it is known that difficult birth requires considerable traction can result in neonatal fractures [10].

Most common fractures during vaginal delivery usually involve the clavicle, humerus and femur [9,10]. Typical site of femoral fracture is the diaphysis, and consequentially the bone is dislocated in flexion and shortened due to the action of the longitudinal muscle [10]. Although femur fracture is a relatively uncommon injury, it represents the most common fracture of the lower extremity in the newborn [11]. Majority of neonatal femoral fractures occur during vaginal breech delivery. Nowadays cesarean section is commonly practiced in breech presentation [12,13] and, although it might reduce the occurrence of traumatic injury [13,14], femur and humerus fractures are still observed [14-17] showing that planning the cesarean section reduces the risk of fracture of long bones but does not eliminate its possibility at all [14]. The multicentre randomized study of Hannah and colleagues showed that the fracture of long bones occurred in 0.5% of cases during vaginal delivery and 0.1% during cesarean section [18]. If diagnosis is unrecognized or delayed, the fracture may go on to a wrong weld joint, causing angular or rotational deformity of the extremity [19].

Fractures of the femoral shaft resulting from birth-related trauma are extremely rare, although they have been reported to occur after difficult deliveries requiring considerable traction [21-23]. This kind of fractures has rapid healing with a short time of treatment [24] with a median time of healing of 30 days and no major complications are reported [25].

We present a case of left femoral shaft fracture in a new-born who presented swelling and tenderness of the left lower extremity on the second day of life. The case has come to our attention because infant’s parents sued for malpractice the medical team who looked after the birth.

2. Case History

A 3900 g female infant, appropriate for gestational age, was born at 39 weeks by primary cesarean section secondary to breech presentation. The mother was a 30 years-old Caucasian primipara, with no history of previous uterine surgery. Pregnancy had far been uneventful with a normal second trimester obstetrics ultrasound and a clinical history negative for gestational problems. Membranes ruptured just before the birth and no cephalic version was attempted to correct the malpresentation. Through a lower segment transverse cesarean section, the obstetrician did not encounter any difficulty in delivering the female baby who cried immediately at birth. Apgar scores were 9 at 1 and 5 minutes, respectively. After the extraction, the baby was subjected to careful clinical examination and routine laboratory tests that showed no abnormalities. Infant was doing well until the second day, when she became irritable and not interested in feeding; she was afebrile and there were no other infection-related signs.

On clinical examination, the infant’s left lower extremity was uniformly swollen from the toes to the inguinal crease, in particular at thigh level. In addition, left inferior limb was shorter than the right, warm, tender to touch and painful during passive movements. Mobility was very decreased compared with the right. Left femoral pulses were felt to be diminished compared to the left side, whereas dorsalis pedis pulses were normal. Range of motion was normal at the hip without any evidence of hip instability or dislocation.

Radiographs revealed a femoral fracture of the shaft at the proximal level with displacement and angulation/displacing anteriorly compared to the middle and distal segment (Figure 1).

Whole body radiographs were performed and did not show fracture of any other bone. The bone structure and mineralization appeared normal; there was no indication of any other fracture/bone deformities or anomalies osteo-articular like blue sclera, osteogenesis imperfecta or hypotonia/Welding-Hofmann disease. The fracture was treated with immobilization with Pavlik harness and three weeks later, follow-up radiograph showed the formation of a callus at the margins of fracture and also an intense periosteal reaction at the femoral shaft so the immobilization was removed at 23 days after birth. On clinical examination the skin thigh appeared regular with no deformities and there was no dysmetria between the lower limbs. The child was able to move her left leg actively in all planes of space without length discrepancy.

Three months after birth, a further control radiogram revealed good healing with a regular bone consolidation and one year after birth, both lower limbs showed a proper mobility with no dysmetria, bilateral flat foot and regular vertebral column. The case came to our attention because it was subject of legal controversy. Parents of the female infant sued for malpractice the medical team who looked after the birth.

3. Discussion

Forced obstetric manoeuvres always carry a risk of soft-tissue injury, long-bones fractures and related neonatal complications [14]. Risk factors include both large and very small foetuses, breech presentation, difficult delivery, inadequate uterine relaxation, small uterine incision, twin pregnancies, prematurity, the advanced age of the mother, primipara status, osteogenesis imperfecta, and osteoporosis [3,26,27]. The most common fractures during vaginal delivery almost always involve the clavicle, humerus and femur [27]. Both vaginal and cesarean section, breech delivery and maneuvers such as external cephalic version were found to be responsible in birth traumas including long bone fractures [28]. In 1922, Ehrenfest first described a fracture of the femur in a newborn associated with a difficult breech extraction during cesarean section [29]. Historically, long-bone fractures have been long attributed to difficult deliveries, in particular to breech presentation, but they are remarkably rare [11]. The role of gender in fracture risk has not been assessed in the published literature.

Breech presentation occurs in 3% to 5% of all single pregnancies. The frequency is even higher in single preterm deliveries (10% to 15%) and twin pregnancies (25%) [30]. Breech presentation is associated with poorer perinatal and neonatal outcomes and is an independent risk factor for a higher neonatal mortality rate [31]. Many studies have shown a significant reduction in perinatal and infant mortality if term breech pregnancies are delivered by planned caesarean section [12-17, 32, 34]. While vaginal breech delivery, although rare, can cause femur fracture, only few reports have described femoral fracture when abdominal breech delivery is performed [22, 35, 36]. Such fracture are caused by forced, sudden traction with twisting and pulling manoeuvres  or when the infant is improperly held by one thigh during delivery of the shoulders and arms [13, 26, 35].

Jain and Bielski have underlined how a history of cesarean section does not rule out the possibility of a fracture and proposed an appropriate extension to uterine incision in order to avoid greater amounts of traction on the extremities during obstetric manoeuvres [19]. Vasa and Kim described seven femoral shaft fractures that occurred during cesarean section [12]. Toker et al. reported one of the largest known series of twelve femur fractures after cesarean section (incidence of 0.308 per 1000) versus 5 fractures in vaginal delivery (incidence of 0.027 per 1000); they stated that the risk of caesarean-related femur fracture in newborns should not be underestimated [37]. In another study, Basha et al. have shown long-bone fractures were more frequently associated with caesarean breech delivery compared with vaginal deliveries; in their study, the incidence birth-related femur fracture was 0.17/1000 live births [2]. Morris et al., reported an estimated incidence of birth trauma of 0.13 to 1 per 1000 [1]; they also have suggested that most of the injuries occurred under general anaesthesia, which correlated with an inappropriate application of force during delivery, and how a good training and supervision of residents could implement safer delivery techniques. Nadas et al., reported the most common risk factors as obstetric manoeuvres (75%), cesarean section (35%), prolonged labor (33%) and prematurity (25%) [38]. In Kancherla’s study, ten cases of femural fracture were described with 60% incidence in cesarean section, particularly predominant with breech presentation [38].

According to Morris and collaborators, the time span from delivery to diagnosis of femur fractures averaged 6.3 days, while the mean period reported by Kancherla is 4 days and by Basha 1.5 days, that it is similar to the time period in our case report. Soft tissue swelling, joint stiffness, focal tenderness and irritability often appear later, and may explain the delay in diagnosis. Since there are few data about the incidence of birth-related femoral fractures, no single treatment regimen for such injuries has been yet proposed. Common and recommended treatment methods reported in orthopaedics literature for femur fractures in neonates include: posterior splinting, spica cast, cast in flexion and abduction, gallows traction, Bryant traction and Pavlik harness [40,41]. Only a single case of external fixator has been described [25].

Pavlik harness was the treatment modality used in our case. This treatment method achieves reduction by bringing the distal fragment in alignment with the proximal one; in addition, it lets the hospital stay to be minimized: in fact the female baby was discharged the day after the Pavlik harness was applied. Stannard and collaborators reported that fracture reduction is easily undertaken by adjusting the straps on the harness [40].

This kind of fractures rapid heal with a short time of treatment. All treatments are given good clinical and radiologic results within 1 month after injury and no major complications are reported.

In recent years there has been an exponential increase of charges against hospitals. From a medico-legal point of view, the case we reported is a very delicate condition because it may involve many health professionals as gynaecologists, obstetrics, neonatologists and also orthopaedics in the difficult case of professional medical liability.

From the study of literature reviews and case reports and the analysis of the medical records of our case, femoral fracture in newborns with breech presentation occurring during cesarean delivery is a rare but possible injury. This kind of complication is not necessarily associated with improper obstetric manoeuvres; femur fractures can occur although the birth is performed accordingly to the most common science and medical knowledge. In addition, in all cases analysed in our literature review, fractures were successfully reduced in a short time, without further complications and with a very good recovery.
