Osteoporosis in patients with fractured femoral neck in Jerusalem.

In an epidemiological survey on fractures of the femur in Jerusalem, the highest incidence occurred in Oriental males and the next highest in European females. In the same series of patients the frequency of senile osteoporosis was noted to be higher in the Oriental group (both male and female) as compared with that in the European group. Similarly in a randomly chosen sample of the population, osteoporosis in the Oriental sector was twice as high as in the European sector. Osteoporosis was also seen to be three to four times more common in each age group when the fracture series was compared with the randomly chosen sample. No evidence of osteomalacia was noted in these patients.

Avascular necrosis of the femoral head after femoral neck fracture.

Trauma-induced avascular necrosis of the femoral head represents the most common femoral head aseptic necrosis. An alteration in blood supply to the femoral head is the cause of the vascular necrosis. Another mechanism in the genesis of femoral head necrosis is the tamponade effect. Femoral head necrosis may be asymptomatic for a long time, even in patients in whom late segmental collapse already is present. Radiography does not allow diagnostic reliability until 6 months after fracture. The presence of a low signal intensity band away from the fracture line on magnetic resonance images clearly delimits the necrotic area. Once segmental collapse has developed, the diagnosis becomes simple using plain radiographs. The treatment of established femoral necrosis complicating fractures of the upper end of the femur is approached as a therapeutic problem lacking an optimal solution. The main therapeutic options are femoral head-preserving procedures and joint reconstruction. Among the procedures that preserve the femoral head are joint unloading, femoral head core decompression, electric stimulation, osteotomy, and bone grafting. Joint reconstruction procedures including cup arthroplasty, hemiresurfacing, total hip resurfacing, femoral head replacement, femoral head endoprosthesis, and total arthroplasty will be reviewed.

Selective depression of metabolic activities in cortical osteoblasts at the site of femoral neck fractures.

The aim of this investigation was to determine whether some metabolic defect might be related to the propensity of osteoporotic femoral necks to fracture acutely. To this end, the activities of two dehydrogenases of the glycolytic Embden-Meyerhof pathway, two of the pentose phosphate pathway, two mitochondrial enzymes, and alkaline phosphatase were measured in the cortical and in the trabecular osteoblasts. Comparison was made with such activities in iliac crest biopsies from patients with these fractures and from the equivalent femoral and iliac crest samples from patients with osteoarthritis of the hip, in biopsies from the iliac crests from seven patients with no bony abnormality, and in specimens from the fracture site of six traumatic fractures. The results showed a highly significant decrease in the activities of the two enzymes of the pentose phosphate pathway (p less than 0.001) in the cortical, but not in the trabecular, osteoblasts in the osteoporotic fractures. This could not be attributed to the trauma of acute fracture since it was not found in traumatic fractures. Other experimental evidence has indicated that a relationship may occur between depressed activity of these enzymes and a retardation of bone formation.

Long-term results after operative treatment of femoral neck fractures with ceramic head prostheses.

From 1985-1990, a total of 277 elderly patients underwent hemiarthroplasty using a ceramic head prosthesis. Average patient age was 81.7 years. Of these, 77 patients were available for follow-up examination in 1993. A standardized score was calculated assessing activity, gait, and hip pain; the average score was 58 out of 78 possible points. Three patients had hip pain, and in 4 patients, radiographic examination revealed protrusio acetabuli. Two of 4 patients underwent revision surgery for replacement of the cup, leaving the stem in situ. Because of the small number of prosthetic-related complications, hemiarthroplasty using a ceramic head prosthesis is the recommended surgical treatment for femoral neck fractures in elderly patients. In the rare patient with protrusio acetabuli, revision surgery can be performed to replace the cup, leaving the stem in situ.

Anaesthesia for surgical correction of fractured femoral neck. A comparison of three techniques.

Sixty patients with fractured neck of femur and scheduled for surgical correction were randomly allocated to receive one of three anaesthetic techniques: general anaesthesia; spinal analgesia; psoas compartment block. The patients in the local anaesthetic groups also received a light general anaesthetic. There was little difference in the pre-, intra- and postoperative events, and no difference in postoperative mortality.

Protrusio acetabuli and bilateral basicervical femoral neck fractures in a patient with Marfan syndrome.

A 22-year-old man with Marfan syndrome and bilateral protrusio acetabuli presented with bilateral femoral neck stress fractures after vigorous stretching exercises for hip "stiffness." Fifteen years later, his fractures, which were treated with internal fixation, have healed, his acetabular protrusion has not worsened, and his perceived hip "stiffness" persists. This case demonstrates a rare manifestation of Marfan syndrome, protrusio acetabuli, and a possible side effect of vigorous stretching in the face of abnormal joint mechanics.
