Bilateral intertrochanteric fractures after surgical treatment of bilateral femoral neck fractures secondary to hypocalcemic convulsions with chronic renal failure: a case report and review of the literature.

There have been no reports of bilateral femoral neck fractures followed by bilateral femoral intertrochanteric fractures. A 28-year-old man presenting with bilateral femoral neck fractures due to generalized convulsions was diagnosed with chronic renal failure and treated with percutaneous screw osteosynthesis and hemodialysis. During rehabilitation, the patient again had convulsions resulting in bilateral femoral intertrochanteric fractures 2 months after the operation. He was treated with a compression hip screw on the right side and conservatively on the left side. This is the first well-documented report on bilateral femoral neck fractures followed by bilateral femoral intertrochanteric fractures.

Videodensitometry of osteons in females with femoral neck fractures.

The medial femoral cortices of 10 females with femoral neck fractures and 10 age-matched female autopsy cases were studied using computer-assisted videodensitometry. Radiographic mineral density was determined using the calibration method described by Martin et al. [20]. Measurements were made of porosity, osteon and haversian canal dimensions, and of interstitial and osteon mineral density across the cortical wall of the orthopedic calcar region. There were no differences between the fracture and nonfracture groups in the overall mean mineral density of the bone averaged over the microstructure, excluding pore space, or in the interstitial bone mineral density. The porosity in the fracture group was greater than in the autopsy group, especially in the periosteal region, where the porosity was 2.4 times greater and where there were also 27% fewer osteons per unit area than in the autopsy group (P < 0.05). Mean osteon mineral density was 2.5% higher in the fracture group (P < 0.05) compared with the autopsy group in the endosteal region, and 4% higher in the periosteal region. Osteon and haversian canal areas were also larger in the fracture group, especially in the middle region of the cortical wall (17% and 23%, respectively, P < 0.05).

[Displaced femoral neck fractures: internal fixation or arthroplasty?].

Femoral neck fractures are a challenge for orthopedic surgeon due to the high rate of complication for such fractures. The aim of this study was to propose a treatment algorithm based on author's current concept in management of femoral neck fractures. Fractures were classified according Garden in four types but, for practical reasons, fractures were considered undisplaced (Garden I and II) and displaced (Garden III and IV). Treatment method was chosen based on next criteria: patient's age, associated pathology, patient's mental status and expectations, quality of the bone (osteoporosis), type and age of fracture, quality of reduction. Based on this criteria, the proposal algorithm may led to close reduction and internal fixation, open reduction and internal fixation or arthroplasty.

Spontaneous subcapital femoral neck fracture complicating a healed intertrochanteric fracture.

A spontaneous subcapital femoral neck fracture is an uncommon complication of a healed intertrochanteric hip fracture. To determine the etiology of this complication, 274 patients who had been treated for intertrochanteric hip fractures were followed up over an 8-year period from June 1988 to June 1996. We found 7 fractures of the subcapital femoral neck without a history of a trauma. The remaining 267 patients were defined as the control group. All seven patients with fractures of the subcapital femoral neck were women, and their average age at the time of compression hip screw (CHS) fixation was 83 years (range 74-92 years). The subcapital fractures occurred between 4 and 36 months after CHS fixation. The difference in the Singh index between the patient and control groups was statistically significant (P < 0.01). However, with regard to the position of the screw, spinal score, age, ambulatory ability, height, weight, and intertrochanteric fracture type (Jensen type), the differences between the patient and control groups were not statistically significant. Based on our findings, we conclude that a high grade of osteoporosis is the most important predisposing factor in the spontaneous development of a subcapital femoral neck fracture after a healed intertrochanteric hip fracture.

[Femoral shaft fracture and secondary diagnosis of ipsilateral femoral neck fracture. Typical constellation or a complication of the distal femoral nail (DFN)?].

We present a case of two patients with a distal femur shaft fracture due to a high velocity trauma. Both were treated with a distal femur nail (DFN). After mobilisation a fracture of the neck of the femur was diagnosed which was not seen in the x-rays on admission. In this paper we discuss whether this is a typical constellation of ipsilateral fractures of the neck of the femur in femur shaft fractures or a complication of implantation of a DFN. Immediately after operative treatment of a femur shaft fracture specifically after high velocity trauma or in polytraumatized patients an x-ray of the hip in two plains should be made in the same narcosis. A possible fracture of the neck of the femur could be treated at same time. Post-operatively a further diagnostic should be done in case of suspicion, e.g. pain during mobilisation.

Prognostic accuracy of preoperative and postoperative scintimetry after femoral neck fracture.

Forty patients with fresh femoral neck fractures treated with closed reduction and internal fixation were included in a prospective study of nonunion and osteonecrosis by preoperative and postoperative scintimetry. Correlated roentgenographic follow-up studies were continued for two years postoperatively. The aim of the study was to determine the relative prognostic accuracy of preoperative versus postoperative scintimetry. A ratio between the radionuclide uptake over the femoral head on the fracture side and the contralateral side exceeding 1.9 at the preoperative scintimetry and 1.2 at the postoperative scintimetry was associated with a high incidence of union, whereas a lower ratio often predicted subsequent complications (redisplacement, nonunion, or late segmental collapse). Prognostic accuracy was higher for scintimetry of fractures treated with closed reduction and internal fixation (0.70) than for untreated fractures (0.53). These results suggest that scintimetry is useful postoperatively to complement roentgenographic examination in assessing the prognosis of femoral neck fractures.

Intracapsular pressure and caput circulation in nondisplaced femoral neck fractures.

Nine patients with nondisplaced femoral neck fracture were evaluated with preoperative Tc-MDP-scintimetry, ultrasonography, and measurement of the intracapsular pressure. The intracapsular pressure in straight neutral position of the hip exceeded normal hip pressure in all cases. Patients with an intracapsular pressure greater than 80 mm Hg had a low scintimetric rate, indicating a risk for segmental collapse of the femoral head. Intracapsular tamponade may contribute to the development of segmental collapse in some patients with nondisplaced femoral neck fracture, but further investigations are needed to determine whether evacuation of the hemarthrosis should be recommended.

Absence of evidence for a role of calcitonin in the etiology of femoral neck fracture.

Twenty elderly women with fracture of the femoral neck were compared with 10 age-matched women undergoing elective hip surgery. In spite of an equivalent calcium response to intravenous calcium, neither basal nor stimulated calcitonin levels were significantly different between the groups. Parathormone, 25OHD, and 1,25(OHD)2 showed no significant differences between the femoral neck fracture group and control subjects. It is thus unlikely that calcitonin has an important role in the etiology of postmenopausal osteoporosis associated with femoral neck fracture.

The fate of the articular cartilage in intracapsular fracture of the femoral neck (articular cartilage in femoral neck fracture).

The fate of the articular cartilage of the hip joint with intracapsular neck fracture was studied by histological, histochemical and autoradiographic techniques and by using a polarized microscope and a scanning electron microscope. Cartilage specimens from 93 femoral heads and 7 acetabula were obtained from fractured hips 2 days to 4 1/3 years postfracture and from control hips with various disorders. The cartilage degeneration appeared 2 weeks after fracture and advanced steadily with time. The matrix was covered, invaded and ultimately replaced by the fibrous tissue. Chondrocyte viability, though it was lost from the surface, was recognized in the deep matrix even in the oldest fracture examined. It is concluded that the humoral factor directly caused by the injury as well as the biomechanical impairment, i.e. a loss of physical stress, may play an essential role in the pathogenesis of the degeneration. The possibility of regeneration was discussed.

Iatrogenic factors in femoral neck fractures.

A study of 200 femoral neck fractures in ambulant patients showed that 62 per cent of subcapital and 58 per cent of trochanteric fractures occurred without a significant history of injury. It was also observed that almost 70 per cent of patients in this group were on long-term medication which could affect bone density. In the remaining patients with a definite history of injury, only 20 per cent and 21 per cent respectively were on long-term therapy, figures which corresponded to the 18 per cent of patients on prolonged medication attending with minor injuries (age- and sex-matched). The action of corticosteroids, thyroxine, phenobarbitone, phenytoin, frusemide and bendrofluazide on bone density and their responsibility for femoral neck fractures are discussed.

Statistical analysis of femoral neck fractures based on 3053 cases.

Femoral neck fractures in 2289 women and 764 men (total 3053) from the years 1975-1977 in Stockholm County Council were retrospectively analyzed regarding social and demographic classification. Seventy-nine percent of the patients (2418 of 3053) were admitted directly from their homes, more commonly in central city areas (82%) than in rural areas (74%). Direct return home was possible in 36%, and 47% could return home after some weeks of institutionalized rehabilitation. There was no increase in fracture incidence found during the three-year period. More fractures occurred on Mondays and less on Sundays than during the rest of the week. The period of December through March showed the highest fracture rate. Diseases other than hip fractures were seen in approximately one-half (1492) of the patients. Internal fixation was performed in 2937 fractures, mainly with the von Bahr screws (1465 cases), Hessel/Nyström multiple pins (674 cases), Thornton nails (380 cases), or Rydell nails (224 cases). Primary hemiarthroplasties were performed in only 102 cases. The detailed analysis of this consecutive population-based femoral neck fracture material is intended as a base for more uniform treatment and rehabilitation of this group of resource-consuming patients.
