[Experimental research of the influences on the development of the hip joints with excavated acetabula].

There are still arguments about the operation excavated acetabula treatments for the congenital dislocation of the hip. To inquire into the influences on the development of the hip joints with excavated acetabula size, we divided 60 two-month-old chickens into three groups which were given incised dislocation and then reduction partly excavated the cartilages of the acetabula and excavated them totally to the left hips respectively. Contrasting observation of all the experimental chickens was taken on the right ones of their own. The second group achieved a fair function of the joint movement. Limited and slight adhesion was not affecting the development of the joints seriously. The third group had, on the contrary, poor functions because of the comprehensive adhesion in the acetabula. The surfaces of the acetabula were replaced by fabric tissue. The remaining or regenerating cartilage cells vary obviously under the light scope and the electronic scope. The heads of the femurs had changed similarly. It is suggested that in dealing with the congenital dislocation of the hip, excavating the acetabola cartilage is not advisable. Partly excavating is permitted when a limited bony process existing in the bottom of the acetabula.

[Loosening of the acetabular implant after replacement of the hip-joint due to age-related loss of bone structure (author's transl)].

Radiographs of the pelvis of 17 patients who after replacement of the hip joint showed loosening of the acetabular component have been examined as to the degree of osteoporosis by the method of Singh et al. Comparing aseptic and infective loosening showed that in aseptic cases age-related loss of bone-substance was on average more pronounced than in loosening due to infection. Since we have stopped opening the cancellous space in patients with advanced osteoporosis but only fill anchorholes or ridges with cement, we have not seen any more aseptic loosening.

Hemarthrosis and hip joint pressure in femoral neck fractures.

In a prospective clinical study the intraarticular pressure of 55 patients with intracapsular femoral neck fractures was measured intraoperatively with the hip in different positions. Intraarticular hemarthrosis was quantified by a preoperative sonography examination. In 75% of the patients, increased intraarticular pressure caused by the hemarthrosis was found. The spontaneous median pressure increased significantly from 22 mm Hg with extension (28 mm Hg) and internal rotation of the hip joint (56 mm Hg). The lowest pressure was found in 70 degrees flexion (15 mm Hg). The median pressures increased within the first 24 hours after injury from 26 mm Hg in the first 6 hours to 46 mm Hg from 7 to 24 hours. Even in the first and second weeks after trauma, increased median pressures were detected (8.5 mm Hg and 13 mm Hg, respectively). No significant difference was found between undisplaced and displaced fracture types. Because increased joint pressure in other studies correlates with reduced perfusion of the femoral head, it can be deduced that reduction maneuvers without capsulotomy can compromise the circulation of the femoral head. Capsulotomy and osteosynthesis of the femoral neck at the earliest time possible is the best prophylaxis of tamponade. If the osteosynthesis is delayed, a preoperative sonography after admission and a control sonogram after 6 hours is recommended. In the event of relevant hemarthrosis, immediate therapeutic drainage is suggested for patients who will receive joint conserving osteosynthesis.

[Functional and radiological assessment of the hip joint after Perthes disease].

Basing a group of 33 patients treat conservatively because of Perthes disease some aspects of functional and radiological assessment of the hip joints is presented. Functional assessment was performed according to the authors' own scale. Radiological assessment was performed basing on Heyman-Herndon method, Klisica method and the authors' own head-trochanter factor and head radius assessment. A comparison of the obtained results was performed, and the clinical usefulness of the authors own head-trochanter and head radius was assessed. The head-trochanter factor correlated to the Heyman-Herndon method allowing assessment of the proximal epiphysis and physis of the femur, while the head radius factor correlated to the Klisica method and allows the assessment of head sphericity, head size and the degree of lateral subluxation of the head.

The use of thoracolumbar and hip joint dysmorphism in identification.

A case of roentgenographic identification of a deceased person is presented. Comparison of antemortem and postmortem radiographs of the vertebral column and hip joint, for the purpose of identification, was based on the deceased medical history, and the fact the deceased was endentulous, and fingerprint comparison was not feasible. Evaluation of anatomical variants, due to the effects of degenerative disease, provided positive identification in a visually unidentifiable deceased person.

Amyloid deposits in human knee and hip joints.

A systematic search for articular amyloidosis was carried out on both knees of 53 autopsy cases and on 26 femoral heads resected during surgery for hip prosthesis. Typical amyloid deposits exhibiting green apple birefringence following Congo red staining and thioflavin T fluorescence were found in 58.5% and 29% of the cases, in the knee and hip joint respectively. They occurred more frequently in articular cartilage than in the synovium, and in elderly subjects more than young ones. In the knee joint, the osteoarthritic changes and to a minor extent synovial inflammation appear to be positively correlated for the presence of intraarticular amyloid deposits. Such a correlation was not observed for the presence of calcium pyrophosphate dihydrate crystal deposits.

Traumatic dislocation of the hip joint--pattern and management in a tropical African population.

Traumatic dislocation of the hip is an orthopaedic emergency for which early reduction is indicated. This article describe our experience of the pattern and choice of management of traumatic dislocation of the hip joint in a tropical African population. Majority of the dislocation (87%) were Thompson and Epstein's grades I and II which were easily managed by closed reduction following the administration of titrated intravenous analgesic and intravenous diazepam. This treatment option is cheap and readily administrable to avoid undue delays in the management of this orthopaedic emergency. All the close reduction were carried out in the accident and emergency room except for one patient with bilateral posterior hip dislocation who had his reduction on the ward. Early diagnosis and treatment of traumatic hip dislocation are essential to reduce the morbidities that are commonly associated with delay in reduction.

Primitive synovial chondromatosis of the hip joint.

Primitive synovial chondromatosis of the hip is quite rare. Through the presentation of four new cases, the authors discuss the pathologic and clinical features of this disease and evaluate the performance of imaging studies, emphasizing the value of CT scan for confirmation of radiographic findings. The indication for surgical treatment is analyzed for each stage of the disease.

Results of alloarthroplasty of the hip joint.

We report on the follow-up examination results of 881 operated hip joints which were implanted in the Innsbruck University Clinic for Orthopedics during the period 1968--1975. Due to exact checking 75% of all patients could be clinically control-examined during 1978 and all available information regarding the others was collected. In the patient group with an average age of 62.5 years the course of postoperative mobility over the years was mainly examined. Functional activity, subjective patient opinion, pain, work capability and weather sensitivity were also analyzed. After an implantation period of the hip prosthesis of 3--10 years encouraging results were shown. Aseptic prostheses loosenings (9.8%) were examined with regard to their causes. The infection rate was very low at 0.56% and also periarticular calcification only occurred comparatively seldom (13.5%). Other complications were recorded in 6.8% of the patients. In total, 74% of the operated patients offered a very good or good complete result.

Enthesopathy of the hip joint.

Morphologically, enthesopathy appears as dystrophic calcification or ossification of tendon insertion. In the study of the initial stages of arthrosis on necroptic material roentgenologically 158 and of these histologically 62 hip joints were investigated. A typical picture of so-called non-inflammatory enthesopathy was present in thirteen cases on the major and in three cases on the minor trochanter. Histologically, we observed enthesopathy-like changes, but to a much lesser extent in the insertions of the articular capsule. These pictures which on the X-ray resembled initial osteophytes were found seven times on the head of the femur and fourteen times on the edge of the joint acetabulum. There was no correlation to osteoarthrosis.

[Experiences with a 3-D ultrasound system in infant hip joints].

AIM: To test the possibilities of 3-dimensional sonography in diagnosing congenital hip dysplasia. METHOD: 128 infant hip joints were examined by 4 investigators with different levels of experience. The Kretz Combison 530 machine additionally equipped with an automatic 5 MgHz transducer and volume box system was employed. RESULTS: The average time to determine the standard plane was 21 seconds. The single standard deviation for alpha values in the 3-dimensional system was 3.0 degrees, compared to 1.37 degrees in the conventional system. Observer experience was not a crucial factor. CONCLUSION: The described 3-dimensional system makes it quicker and simpler to determine the standard plane when evaluating infant hips. The higher standard deviation is possibly caused by the obliquity of the ultrasonic beam. Ossification defects on the acetabular roof are better visualized with this approach than with conventional ultrasound or radiological methods. Even though 3-dimensional ultrasound represents a new approach to infant hips, it seems worthy of rapid development.

[Obturator dislocation of the hip joint].

Luxatio obturatoria may occur in the case of a trauma affecting the hip joint when the latter is in a position of flexion, abduction and external rotation. The femoral head dislocates anteriorly and caudally towards the foramen obturatum. A recent case will be presented with a discussion of the general aspects of this injury, with special emphasis on concomitant injuries and their significance of the long-term prognosis.

[Metal spongiosa endoprostheses for surgical revision of the hip joint].

On the basis of 60 revision operations which were carried out on hip joints with mainly aseptic loosened cemented endoprosthesis and which also had, to some extent, distinct macrophagic induced osteolysis zones, it could be shown that implants with a metal spongiosa surface structure offer a good chance of an enduring revitalisation in the anchorage position and, thereby, are able to achieve a permanently stable endoprosthesis fixation. The expansion defects could be filled by means of homologous or autologous spongiosa transplantation. The post-operative X-ray check-up showed a vital inward-growing healing. All the endoprosthesis remained in situ during the follow-up examination period of, on average, 12.1 months. In accordance with the Merle D'Aubigne hip evaluation scheme, 43.3% showed an excellent result; 40% a good one; 13.3% were satisfactory; and only 3.4% showed a bad result. Major complications which occurred were: two intra-operative femoral stem fractures which had to be taken care of osteosynthetically; a repeat operation which had to take place during the first post-operative week because of a dislocation of the socket cup; and a luxation which was revised under narcosis. In spite of an increased periarticular ossification's ratio in revision operations, second-class ossification only occurred in 16.7% of all cases and third-class ossification did not occur at all.

Congenital dislocation of the hip joint in northern Sweden.

The incidence of neonatally diagnosed congeital dislocation of the hip joint (CDH) was found to vary between three hospitals in Northern Seden. The incidence was 10.0, 7.1 and 3.5 per thousand in hospitals A, B and C, repectively. The incidence increased during the period 1960-73 in hospitals A and B, but not in hospital C. At these hospitals the number of cases needing prolonged orthopaedic treatment showed an inverse relationship to the incidence of neonatally diagnosed CDH.
