Osteoarthritis of the hip joint and osteoporosis: a radiological study in a random population sample in Jerusalem.
The prevalence of osteoarthritis of the hip and osteoporosis of the pelvis were examined in a random population sample in Jerusalem. Of the subjects reviewed, 16.1% showed osteoporosis of the pelvis, while osteoarthritis was noted in 4.1%. In only 0.5% did osteoarthritis and osteoporosis coexist in the same individual. Osteoporosis was more prevalent in the Far East population, while osteoarthritis appeared to bear no relationship to ethnic origin. It is suggested that osteoarthritis may be associated with high levels of physical activity, a characteristic of some Eastern populations.

The hypermobility syndrome. Musculoskeletal complaints in 100 consecutive cases of generalized joint hypermobility.
The hypermobility syndrome, also known as congenital laxity of ligaments and joints, occurs as an isolated condition. The genetic background is distinct from that found in other connective tissues disorders. Although joint hypermobility is relatively common in the general population, reports of musculoskeletal complaints are infrequent. An analysis of 100 consecutive cases with various musculoskeletal complaints associated with joint hypermobility demonstrated differing patterns of presentation. One group had mild musculoskeletal complaints of long duration, while another had acute episodes of pain at various sites. A third group had combined features of the first two groups. Many of the patients had complaints referable to feet and calves, while a number related to problems due to patellar hypermobility. The treatment is exercise to develop protective reflex reactions and to strengthen the surrounding musculature. Surgery must be advocated with care and is reserved for patients with secondary arthrosis.

A simple radiological screening method for assessment of osteoporosis.
A simple radiological grading of osteoporosis of the hand using a postero-anterior radiograph is presented as a screening technique. Five gradings are discussed, and the relationship of osteoporosis between the hand and axial portions of the skeleton is underlined.

Determination of osteoporosis in patients with fractured femoral neck using the Singh index: a Jerusalem study.
The Singh index was used to measure the degree of osteoporosis in patients with fracture of the neck of the femur and to compare its prevalence with a random population sample in Jerusalem. The frequency of osteoporosis was 22.7% among women in the fracture series as compared with 1% in the control group. These figures are much lower than those in comparable series. The Singh index was not as sensitive an indicator of spinal osteoporosis as a direct measurement of vertebral bone density and could not be correlated with the incidence of hip fractures.

The cleavage intercondylar fracture of the femur.
The mechanism of injury and long-term effects in three cases suggest that a specific type of intercondylar injury of the femur, i.e., cleavage fracture, is caused by force transmitted through the patella. Treatment is conservative. The fracture does not appear to have been mentioned previously in the English literature.

Effect of pelvic inclination on the pathogenesis of congenital hip dislocation.
The relationship of the pelvis, acetabulum, spine and femur was studied in the adult in the newborn. It was noted that when the flexed spine and pelvis derotated at or soon after birth, the femoral head dislocated anteriorly in a number of anatomic preparations, and, in the process of "unfolding," the femoral head assumed the classically recognized dislocated position. The "weak" areas in the fibrocartilaginous makeup are also described.

Pelvic obliquity as a factor in dysplastic hip in infancy.
Screening of the newborn to detect hip dysplasia has led to the increasing recognition of fixed pelvic obliquity, in which one hip has restriction of abduction and the other, restriction of adduction. The hip with limited abduction is apparently short, so that the infant presents signs clinically indistinguishable from those of congenital dislocation. During the years 1974-78, 192 consecutive cases of unilateral dysplastic hips were treated by us; 44 (23%) were diagnosed as having pelvic obliquity. Nine were males and 35, females; 39 were firstborn. A characteristic postural pattern was found on examination. If untreated in the early stages, a morbid degree of subluxation developed and in six cases, complete dislocation occurred. In 33 cases, complete resolution of abduction contracture and subsequent pelvic obliquity occurred within the first year of life. In a number of cases, pelvic obliquity persisted for years and in a few, resulted in physical incapacity.

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.

A practical approach for lateral meniscectomy.
A variant surgical approach to the lateral meniscus is described in an effort to overcome the difficulties encountered in the region of the anterior horn of this meniscus. The knee is braced in 90 degrees of flexion and the incision is made from the lower lateral side of the patella, extending down and back for 4-5 cm.

Osteochondroma following irradiation. Case report and review of the literature.
A case of an osteochondroma of the distal radius appearing 10 years after irradiation for hemangioma in infancy is described. The literature is reviewed and the effects of irradiation on bone growth, and possible malignant change, are discussed.

Osteoporosis of the spine, pelvis and hand. A comparative study in a femoral neck fracture series.
In a comparative study of the degree and prevalence of osteoporosis in the hand, pelvis and spine of a group of femoral neck fractures in the elderly, it was noted that spinal osteoporosis was much more frequent and appeared much earlier than pelvic osteoporosis. Similarly, a one way correlation existed between osteoporosis of the hand and spine. No relationship was noted between osteoporosis of the pelvis as measured by our criteria and by the Singh technique.

The epidemiology of femoral neck fractures in Jerusalem. A prospective study (1967-1971).
A prospective study of 570 patients with fracture of the upper end of the femur was carried out between 1967 and 1971 in Jerusalem. Of three distinct ethnic groupings, Western or Ashkenazi females and Eastern or Sephardi males produced the highest incidence of fractured neck of the femur proportional to their makeup in the population at risk. No explanation for this is forthcoming as both groups are of differing sex and race. The age and sex incidence of these fractures in the Eastern and Western ethnic groups in this city showed a distinct resemblance to their geographicaly counterparts in other studies. There is an interesting seasonal pattern of incidence of fractures in females and correlation with increased physical activity during the three special holiday periods.
