Posterior dislocation of the hip with ipsilateral displaced femoral neck fracture

Traumatic posterior dislocation of hip associated with ipsilateral displaced femoral neck fracture is a rare injury. Moreover, the management of such patients evokes strong views regarding primary replacement or preserving the femoral head. We presented a case of young adult with such an injury. He was operated upon with reduction of the dislocation and fixation of femoral neck fracture with the help of cancellous screws. Two years later, the fracture had united and the patient was asymptomatic. We further proposed the mechanism of injury for such a fracture and discussed the management in the changing trauma scenario of the developing world.     

Three part posterior fracture dislocation of the hip without fracture of the femoral head: review of literature and a case report

This case report describes a rare posterior dislocation of the hip with fractures of the ipsilateral femoral neck and greater trochanter, without fracture of the femoral head, in a young adult male following a railway accident. This patient was managed within 6h of injury by open reconstruction. This unusual injury has not been reported previously. Cases of posterior fracture dislocation of the hip with a fracture of the femoral neck without fracture of the femoral head were reviewed from the literature. Mechanism of injury, controversies regarding operative procedures and appropriate surgical approach are discussed. The authors also believe that this injury pattern merits inclusion in the existing classification system of fracture dislocation of hip for management and prediction of outcome.     

Transient epiphyseal lesion of the femoral head after traumatic hip dislocation: A case report

IntroductionWe experienced a rare case in which magnetic resonance imaging (MRI) showed a transient epiphyseal lesion of the femoral head four months after traumatic hip dislocation. To our knowledge, there have been no previously published reports on the development of such transient lesions after traumatic hip dislocation involving no abnormalities just after dislocation.Presentation of caseWe report a 22-year-old man who showed a transient epiphyseal lesion of the femoral head after traumatic hip dislocation. On MRI performed two days after dislocation, no bony injuries were observed around the hip joint. Four months after dislocation, the patient suddenly experienced right hip pain without any new trauma or injury. A low-intensity band convex to the articular surface was apparent above the epiphyseal scar on T1-weighted imaging, and bone marrow edema was observed around the band lesion on short-tau inversion recovery imaging. Following a two-month period of non-surgical conservative therapy, the patient’s hip pain resolved and the low-intensity band was no longer observed on follow-up MRI.DiscussionAlthough the detailed pathogenesis of this transient changes was unclear, we speculate that prolonged rest after traumatic hip dislocation may contribute to bone insufficiency, resulting in an insufficiency fracture of the femoral head.ConclusionThis study suggests that transient epiphyseal lesions of the femoral head may occur in patients with a history of traumatic hip dislocation associated with an adapted long-term rest.     

Posterior dislocation of the hip with concomitant ipsilateral fractures of both the femoral head and shaft: A case report

Summary we report a rare injury in a 32-year-old man victim of a high-energy motor vehicle accident who sustained a posterior hip dislocation with concomitant ipsilateral fractures of both the femoral head and femoral shaft. Closed reduction of the hip was attempted but failed. Surgical approach was necessary to reduce the hip and then femoral nailing was performed. The femoral head fragment was neglected. The patient died after 2 days of neurological complications. Combination of posterior hip dislocation with ipsilateral femoral shaft and head fractures is unusual.     

Pubic-type dislocation of the hip combined with fracture of the ipsilateral greater trochanter

Summary Traumatic anterior dislocation of the hip is a relatively uncommon injury, and when it does occur it is frequently combined with osteochondral fracture of the femoral head or the acetabulum. Anterior dislocation of the hip with an associated fracture of the ipsilateral greater trochanter is extremely rare. This paper presents a case of this rare type of injury and clarifies the mechanism of the injury using a cadaver specimen.     

Traumatic anterior dislocation of the hip associated with ipsilateral femoral shaft fracture in a child: a case report

Traumatic anterior dislocation of the hip joint in children is rare, and only one case with ipsilateral femoral fracture has been reported in Japan. We report a case of such dislocation and a review of the literature. The patient was a 31-month-old girl who was injured in a car accident while asleep on a tilted front passenger seat. Radiographic examination showed dislocation of the right obturator foramen and transverse fracture of the ipsilateral femoral shaft. The dislocation of the right hip was easily reduced without anaesthesia during radiography. We applied Bryant traction after reduction for 4 weeks, followed by cast application for 3 weeks. Walking with support and full weightbearing were permitted 14 weeks and 16 weeks after the injury, respectively. Radiography at 4.5 years after the injury showed a mildly enlarged right femoral head and femur overgrowth of approximately 8 mm. Magnetic resonance imaging showed no evidence of suspected avascular necrosis of the femoral head. The patient has no subjective or objective symptoms, and is able to engage in all usual activities. The detailed mechanism of the injury is unknown. We assume that the lower leg was dislocated through abduction during flexion, or abducent, external flexion, considering that the child was sleeping at the time of the accident. Since she was hurled to the back seat, it was assumed that strong external force was vertically added to the femur, which caused the abducent force.     

Surgical treatment and prognosis of acetabular fractures associated with ipsilateral femoral neck fractures

Combined ipsilateral acetabular and femoral neck fractures are the result of high-energy trauma. Satisfactory treatment for this injury pattern remains a challenge, since traditional open reduction and internal fixation (ORIF) is always accompanied by a high prevalence of posttraumatic arthritis and avascular necrosis of the femoral head. Eight of 502 acetabular fractures from 1990 to 2008 were diagnosed with combined ipsilateral femoral neck fracture, in which 5 patients' fractures were associated with hip dislocation. These patients were injured from falls, traffic accidents, or crushing accidents. Radiographs and computed tomography scans were taken to check acetabular and femoral neck fractures. All of the patients underwent surgery using appropriate approaches and techniques. Postoperative radiographs demonstrated anatomic or satisfactory reduction for acetabular fractures as well as excellent or good reduction for femoral neck fractures in all of the patients. Follow-up radiographs showed femoral head necrosis in the 5 patients with femoral head dislocations, but not in the other 3 patients. We have seen few patients with this injury pattern, which makes us unable to detect significant differences between the patients associated with femoral head dislocation and those without femoral head dislocation. But by considering the results of our study and those reported in the literature, we believe that for patients with ipsilateral acetabular and femoral neck fractures without hip dislocation, satisfactory results could be expected after ORIF. But for those cases associated with hip dislocation, alternative methods such as acute THR as primary treatment are worthy of consideration.     

Bilateral femur fractures are associated with concomitant femoral neck fracture

Objective

The purpose of this study is to determine the rate of femoral neck fractures in patients who have sustained bilateral femur fractures compared to unilateral femur fractures.

Design and setting

A retrospective review of an institutional trauma database was completed at a single level 1 trauma academic medical center.

Patients

All patients treated for a femur fracture between May 1, 2018 and December 31, 2020 were included.

Results

Twenty-one patients sustained bilateral femur fractures (11%) and 166 sustained unilateral femur fractures. Fifteen associated ipsilateral femoral neck fractures were identified. Eight of the 15 (53%) associated femoral neck fractures were observed in patients who sustained bilateral femur fractures. Eight of the 21 patients with bilateral femur fractures, 42 fractures in total, had an associated ipsilateral femoral neck fracture (38% of patients; 19% of fractures, respectively), while only seven of the 166 patients (4%) with a unilateral femur fracture had an associated femoral neck fracture (p < 0.001). Of the 208 femur fractures, 19 (9%) were open fractures. Ten of the 21 patients with bilateral femur fractures, 42 fractures in total, were identified to have an open femur fracture (48% of patients, 24% of fractures), while only nine of the 166 (5%) unilateral femur fractures were open (p < 0.001).

Conclusions

Our results demonstrate an association between bilateral femur fractures, open femur fractures, and associated femoral neck fractures. Surgeons treating these injuries should maintain a high index of suspicion for associated ipsilateral proximal.

     

Retrograde femoral interlocking nail in complex fractures

Retrograde interlocking nail was used as the method of fixation in 35 different cases of combination of complex femoral fractures. We performed this procedure in fractures of femoral shaft associated with fracture neck femur, pathological fractures of proximal third of femur with trochanteric pathology, ipsilateral fracture of femur and tibia in polytrauma cases with multiple other injuries, in highly obese patients with fracture shaft femur. This technique was also used in cases of pregnancy with fracture shaft femur and in unstable pelvic fracture or dislocation hip associated with fracture shaft femur. Operative technique involved with retrograde insertion of un-reamed, non-cannulated custom made nail through entrance portal in intercondylar notch was applied for fixation of the shaft femur fracture. The other associated fracture around hip was stabilized separately using suitable implant according to type of fracture. In cases of ipsilateral fracture of femur and tibia, femur was stabilized by retrograde interlocking nail and tibia was stabilized by antigrade interlocking nail through same incision at the same sitting. The case was followed up for three years; the average union time was 12 to 18 weeks. Out of 35 cases, 31 cases regained full knee movement. Out of the remaining 4 cases, 2 cases could regain up to 90 degrees of movement, these were old fractures and non-cooperative patients. In one case, patellofemoral arthritis was developed because of an operative error where a nail was not put inside the articular surface. Mal-union was observed in an early case of the series and implant failure was nil. Retrograde interlocking nail was used as the method of fixation in complex fracture problems. Multiple fractures of long bones can be stabilized in one stage, preventing multiple operations at different stages in polytraumatized patients. This resulted in early recovery, lesser hospital stay, and early rehabilitation of patient with good results and is economical also.     

Surgical dislocation of the hip for fractures of the femoral head

Traumatic dislocations of the hip are high-energy injuries that frequently occur with fractures of the femoral head. Controversy exists regarding many aspects of the treatment of these fractures, but following reduction, large displaced head fragments require open reduction and internal fixation. Traditionally, an anterior approach to the hip joint has been used for surgical access to the femoral head, but this incision often results in limited visualization and subsequent difficulty with anatomic reduction. Recently, a surgical hip dislocation technique has been described for acetabular fractures and deformities of the proximal femur. At our institution, this technique has been used for femoral head fractures resulting in superior visualization and fracture stabilization. This article details the technique and its application.     

Treatment of ipsilateral hip and femoral shaft fractures with reconstructive intramedullary interlocking nail

Objective: To evaluate the results of reconstructive intramedullary interlocking nail in the treatment of ipsllateral hip and femoral shaft fractures. Methods: From August 1997 to November 2001, 13 patients were treated with the reconstructive intramedullary interlocking nail. Nine patients were associated with ipsllateral femoral neck fractures, three with ipsilateral intertrochanteric fractures, and one with subtrochanteric fracture. Results: The follow-up time was from 6 to 38 months with an average of 14 months. All the femoral shaft and hip fractures healed up well. There was no nonunion of the femoral neck, and only one varns malunion. No patient had avascular necrosis of the femoral head. The average healing time for femoral neck fracture was 4.6 months and for shaft fracture 5.8 months. The joint movement and other functions were fairly resumed. Conclusions: The reconstructive intramedullary interlocking nail, with less trauma, refiable fixation, and high rate of fracture healing, is an ideal method of choice in the treatment of ipsilateral hip and femoral shaft fractures.     

Traumatic hip dislocation with ipsilateral femoral shaft fractures

A traumatic dislocation of the hip joint associated with an ipsilateral femoral shaft fracture is a rare injury resulting from severe trauma. Initially the dislocated hip joint is often unrecognized and consequently reduction is delayed. Early diagnosis and reduction of the hip joint improves the functional prognosis. The maximum functional recovery is possible only with greater awareness of this combined injury. Examination of the hip joints by clinical roentgenography in the critically injured patient, especially those with head injuries, or physical signs masked by extremity swelling, should be a routine procedure.     

Ipsilateral femoral fracture and anterior hip dislocation in a 15-year-old girl: case report

Operative management of concomitant ipsilateral femur fracture and anterior hip dislocation has not been previously described in the literature. We report the case of a 15-years-old girl who was injured in a motorcycle accident and presented with a femoral shaft fracture and a concomitant ipsilateral anterior hip dislocation. Operative management consisted of an attempted closed reduction of the femoral fracture, which was unsuccessful; thus, an external fixator was temporarily applied. Subsequently, the hip dislocation was treated by open reduction through an anterolateral approach. Finally, the femoral fracture was securely stabilized using an unreamed femoral intramedullary nail. The postoperative course was uneventful. MRI follow-up after 6 weeks did not reveal any sign of mangled vascularization of the femoral head and radiographs demonstrated normal bony healing of the shaft fracture. Due to the fact that there is no definitive surgical strategy for this rare combination of injuries, concomitant ipsilateral femoral fracture and anterior hip dislocation is an interesting and challenging situation for the trauma surgeon which requires a subtle and exact surgical technique in order to achieve satisfying results.     

Anterior perineal dislocation of the hip with fracture of the femoral head. A case report

Traumatic anterior perineal hip dislocation with an associated fracture of the femoral head is a rare entity. A 26-year-old man injured in a motorcycle accident was treated by closed reduction of the dislocation within three hours after admission. However, several reports of patients with anterior hip dislocation with associated femoral head fractures were treated nonoperatively and had unfavorable results when treatment failed to achieve anatomical position of the fragments. Consequently, this patient was treated by open reduction and internal fixation of the fractured fragment. Follow-up examination three and one-half years after the operation showed painless functional range of hip motion with only minimal discomfort after prolonged exertion.     

Terrible triad of the hip: A case report

IntroductionPipkin-III femoral head fracture dislocation is a rare injury and its outcome is guarded. Some authors believe femoral neck fracture of Pipkin-III injury is largely iatrogenic. Recent literature showed none of these injuries had excellent outcome, and most patients end up with hip replacement.Presentation of caseA 34-year-old man sustained a traumatic hip injury with fracture-dislocation and an iatrogenic femoral neck fracture during reduction. A modified Gibson approach was performed to reduce and fix the femoral head and neck fractures in a retrograde fashion. Follow-up at 26 months assessment showed viable femoral head, and excellent functional outcome.DiscussionIatrogenic femoral neck fracture in the setting of femoral head dislocation is not uncommon. Clinical and radiological signs of irreducible dislocation can easily be missed which might lead to devastating complications like iatrogenic femoral neck fracture. Recognition of this unique injury, timely intervention, and meticulous dissection might positively alter the patient’s outcome.ConclusionThis case serves to enlighten orthopedists about the risk of iatrogenic femoral neck fracture, methods to avoid such complication, and the proper management.     

Anterior dislocation of hip with ipsilateral femoral neck and head fracture

A 70-year-old male patient presented to our emergency department with trauma left hip following a fall. Physical examination revealed external rotation, slight flexion, adduction, and shortening of the affected limb. There was a palpable fullness in the groin. Radiographic examination revealed fracture neck of femur with femoral head dislocated anteriorly and lying in the obturator foramen. There was an associated femoral head fracture with a fragment of it in the acetabulum. Although this sort of injury has been reported once, the difference in our case lies in the age of the patient; the injury complex was caused by a less severe trauma and a unique mechanism of injury. Also a modification of Brumback classification is proposed to include such fractures more specifically in order to allow comparative analysis in such rare injuries as more and more such case reports are added to literature.     

Dilemma for Fracture Fixation of Paediatric Ipsilateral Neck with Shaft Femur Fracture

BackgroundIpsilateral femoral neck with shaft fracture (IFNSF) in the paediatric population is a rare injury. This high-impact trauma is often associated with other orthopaedic and systemic injuries. Prognosis is usually guarded as both these osseous injuries are serious and exist together. We report two such patients of IFNSF.MethodsTwo children with IFNSF were admitted at our hospital in 2018. The first patient had an associated head injury, while in the second patient, the shaft femur fracture was open. We report on the treatment and results in these two patients. Both the patients were serially assessed and followed 2 years after the injury.ResultsUnion was achieved in neck and shaft femur fractures in both the patients by 3 months. Complications like avascular necrosis (AVN) of the femoral head, coxa vara, non-union or malunion of fractures, limb length discrepancy, knee and hip stiffness were not seen in either of the patients.ConclusionIFNSF is a rare injury pattern seen in children, usually associated with concomitant orthopedic and other systemic injuries. Early operative stabilization is the preferred modality of treatment. For an undisplaced neck fracture, a provisional temporary fixation of a relatively less displaced neck fracture, definitively stabilizing the shaft fracture, and thereby returning to fix neck fracture is advocated. For displaced neck fractures, a direct open reduction is advocated. Anatomical fixation with separate implants and a relatively longer immobilization can provide the best-expected results. Long-term follow-up is needed to foresee any complications.Level of EvidenceV (case series).

Open anterior dislocation of the hip in child of 7-years-old: A case report and literature review

Traumatic hip dislocation is a rare injury in children, and an open dislocation is exceptional. We report the case of a 7 year old patient who presented an open anterior dislocation of the left hip following trauma by accident of the public highway. The patient received treatment under general anesthesia: articular toilet, debridement and reduction. Then, He was put under traction for 6 weeks and antibiotic. The short term evolution is marked by the occurrence of post-traumatic septic arthritis and osteonecrosis of the femoral head after two months.

Obturator hip dislocation with ipsilateral fractures of the femoral head and femoral neck. A case report

A 28-year-old female pedestrians, struck by an automobile, sustained an obturator hip dislocation with concomitant ipsilateral fractures of both the femoral head and femoral neck. This unusual hip injury seems not to have been previously reported. The femoral neck fracture was widely separated from the shaft, and unfortunately, a 6-mm deep indentation fracture involved the anterosuperior portion of the articulating surface of the femoral head. This complex injury was treated with a press-fit bipolar prosthesis.
