Etretinate-induced heterotopic bone formation about the hip joint. A case report including ultrastructural study.

Despite considerable documentation for retinoid-induced hyperostosis, sufficient knowledge regarding its management and histologic features is not available. In a 26-year-old man with etretinate-induced heterotopic bone formation about the hip joint, the use of etidronate disodium was unsuccessful. Surgical excision of the heterotopic bone dramatically improved restricted motion of the hip joint without initiating significant postoperative heterotopic ossification. Ultrastructural study showed abundant myofibroblasts in the fibrous tissue close to the heterotopic bone. Their role in local biologic events should be determined.

[Hip joint endoprosthesis and metal sensitivity. Studies using the leukocyte migration test].

The Leukocyte-Migration-Test (LMT) is a sensitive method for the proof of metal sensitivity in organism. There were no difference in the sensitivity of chromium, cobalt and/or nickel in 42 patients suffering for coxarthrosis and 41 patients after total hip replacement. We found no connection between metal sensitivity and loosening of artificial hip joints in two groups of patients suffering as well from metal sensitivity as from loosening of the artificial hip joint.

[Errors in reconstructive-rehabilitative operations on the hip joint].

Based upon the analysis of 1015 case records of patients, aged 16-70, with different hip joint pathology types, carried out during 1985-1990, there were revealed mistakes and complications after reconstructive-restorative operations. In the group of patients with dysplastic coxarthrosis they noted rather frequent (12% of cases) formation of "tectum" in supratrochanteric region that served as the cause of joint instability and development of arthrosis in future. Cartilaginous limbus, not removed at grave forms of dysplastic coxarthrosis, served as the cause of the pain syndrome in 63% of cases. Carrying out of "osteotomy-medicate" only in patients with aseptic necrosis of femoral head was ineffective in 38% of cases. Total removal of necrotization foci in thigh head with subsequent osseous plasty is necessary. In the process of mobilization operation in case of hyperplastic, coxarthrosis, removal of the lower edge of cotyloid cavity is the obligatory step. Thus, the important condition of favourable terminations of reconstructive-restorative operations is the correct selection of indications, carrying out of complete surgical intervention, rigorous observation of the patient control rules in near and distant postoperative period.

Biomechanics of the hip joint.

A great deal of biomechanical research remains to be done in the area of hip joint trauma so that bioengineers and other medical scientists can work with accurate bone failure data, which are essential to the design of sports equipment, vehicles, workplace situations, and prostheses. The application of biomechanical data, in addition to being essential in prosthesis design and ergonomics, also can be useful in such diverse problems as pathogenesis of degenerative joint disease, management of the postfracture patient, bracing in Perthes' disease, and in many other pathologic conditions.

Giant synovial cyst of the hip joint.

Synovial cysts are known to occur in patients with rheumatoid arthritis. Their presentation in the hip joint, however, continues to be a diagnostic challenge. A case is presented involving a patient with a large synovial cyst of the hip, emphasizing the need for the orthopaedic surgeon to include synovial cyst in the differential diagnosis of a painless groin mass, particularly in patients with rheumatoid arthritis.

The holistic approach to rehabilitation of patients after total hip joint replacement.

AIM: The objective of the present study was to present the principles of a program used jointly by the Clinic of Orthopaedics and Traumatology and the Clinic of Physical Medicine and Early Rehabilitation at St. George University Hospital, Plovdiv for rehabilitation of patients with total hip replacement surgery. MATERIALS AND METHODS: We reviewed 486 cases of endoprostheses implanted by two surgical teams in the Clinic of Orthopaedics and Traumatology over a period of 6 years. We lay the stress on the fact that early mobilization of patients (3 to 5 days after operation) results in better functional results. We particularly emphasize the necessity of using a comprehensive approach that can have an effect on the psychoemotional status and the motivation of patients. RESULTS: The treatment results we evaluated by taking into account not only all functional parameters of restoring the range of hip joint motion but also the psychoemotional aspects of the recovery of patients after surgery. We took into consideration the range of motion of both the operated and the unoperated hip joints, the muscle strength, the walking distance, the type of gait, and the subjective evaluation of the patients (satisfied, not very satisfied, unsatisfied of operation). Particular attention was paid to the psychoemotional status of patients stimulating the positive feedback and their willingness to put in serious efforts toward improvement of their quality of life. CONCLUSION: The new approach to rehabilitation of patients with total hip replacement focuses not only on the collaboration between orthopedists, traumatologists and physical therapeutists, but also on the integral effect both on the physical state of patients and on their psychoemotional status with the aim of improving their quality of life.

Amyloid in osteoarthritic hip joints. Depositions in cartilage and capsule. Semiquantitative aspects.

Amyloid depositions in tissue from 116 osteoarthritic hip joints were examined. There was no significant correlation between amyloid and age although there was a tendency for joints from older patients to have more marked amyloid degeneration. We found significantly more amyloid in the joint capsules from male patients than from females. No difference in amyloid deposition was found between the right and left side, and pressure-loaded/less pressure-loaded parts of the femoral head contained equal amounts of amyloid. With the exception of two cases amyloid depositions in the joint capsule were always accompanied by amyloid in the joint cartilage (P less than 0.001). Conversely the cartilage was often positive when the capsule was negative for amyloid.

Dynamic analysis of the resultant force acting on the hip joint during level walking.

The present study was designed to determine the resultant force acting on the hip joint during walking using a new dynamic analysis method. Our model utilized joint motion, ground reaction force, and muscle strength data from 18 women (6 normal women aged 20-24 years, 6 normal women aged 50-57 years, and 6 female patients with osteoarthritis, aged 50-66 years). We analyzed the resultant force using the multibody dynamic analysis system. To determine the factors that influence the force acting on the hip, we examined the effect of age and total hip arthroplasty. The maximum resultant force acting on the femoral head was dependent on the subject body weight and correlated with muscle strength and walking speed. The results of this study highlight the agreement between computer simulation analysis and actual measurement of the resultant force acting on the hip. Our results suggest that muscle strength and walking speed are significant determinants of the resultant force acting on the hip.

[Different indications for endoprotheses of the hip joint (ceramics (Al2O3) or internal shells?) (author's transl)].

The internal shell endoprothesis for the hip joint after Wagner has considerably limited the indications for the implantation of ceramic endoprotheses to patients under 60 years, because less bone substance has to be sacrificed. Furthermore there are indications for ceramic endoprotheses in cases of substance defects of the femoral head and neck, to some extent also in cases of dysplasia and protrusio acetabuli, and by loosening traditional total hip endoprotheses.

[Biorhythmical characterization of exacerbations of the degenerative-dystrophic process in patients with the impaired hip joint].

The age-dependent structure of the contingents treated conservatively at the local outpatient clinics (197 women aged 17-82 and 59 men aged 25-85) and patients subjected to operations of total endoprosthesis of the hip joint for coxarthrosis (663 women aged 19-89 and 304 men aged 22-82) was investigated. The structure of the indices under study was found to fluctuate with the average period length 10.7 years (sigma = 2.7 years), 8.2 years (sigma = 3.5 years), 7.3 days (sigma = 3.0 years), 9.5 years (sigma = 2.1 years) respectively. A comparison of the fluctuation curves of the age-dependent structure of the women treated conservatively and operated upon showed the coincidence of the maximums in 35, 43, 60, 65, 69, 74-74 years of age, in men--in 34-35, 41, 75-76. It can be supposed that the revealed age-dependent fluctuations of activity of the inflammatory process and the pain syndrome correspondingly might be considered as an element of the periodic disease in pathogenesis of degenerative-dystrophic lesions of the hip joint.

[An analysis of the selected parameters of the normal hip joint during growth in magnetic resonance imaging].

Dynamics of the selected parameters of the normal hip joint during growth has been presented. Fifty-three normal hips in 40 individuals aged 3-17 years were assessed with Magneton Impact MRI. The angles and indices were found on T1 coronal images in Spin Echo or Turbo Spin Echo sequence. Acetabular roof angle of Hilgenreiner, acetabular inclination angle of Sharp, Wiberg angle and Heyman-Herndon index were calculated with both bony and cartilaginous elements regarded. Parameters based on cartilaginous parts of the joint did not change during normal growth, but they do change if calculated with the use of bony landmarks reaching Acartilaginous values by the age of 14-15. The results suggest, that during growth gradual ossification of cartilaginous elements takes place but the proportions remain unchanged. The investigation determines the age of enhanced ossification and the age of its termination.

Is there a difference in hip joint position sense between young and older groups?

BACKGROUND: Joint position sense (JPS) in the knee has been shown by many authors to decline with age. It has been speculated that this decrease contributes to abnormal joint mechanics during load-bearing activities and putatively results in joint degeneration. Surprisingly little research has been conducted on the human hip to determine benchmarks for normal JPS. METHOD: Fifty-nine community dwelling subjects, 30 young (mean age 21.7 years) and 29 older (mean age 75 years), were recruited to determine normal reference ranges for the effect of age on hip JPS. Active and passive repositioning tasks were performed in inner and outer ranges of the hip abduction plane of movement. An electromagnetic tracking system was used to obtain accurate error measurements of the angular displacement. RESULTS: Results indicated no difference in hip JPS between the young and older subjects (F(1,57) = 0.011, p = .917). However, it was found that for both age groups, accurate reproduction of position at the hip joint occurred in the inner range (F(1,57) = 13.760, p < .001). For both groups, active repositioning was more accurate than passive (F(1,57) = 9.265, p = .004). CONCLUSIONS: In this study, no difference in hip JPS was found between young and older subjects. Accuracy was greater in the inner range, with active repositioning demonstrating higher precision compared to passive repositioning of the limb.

Assessment of methods of anaesthesia used for total alloplasty of hip joint with application of bone cement.

The authors analyse 151 cases of anaesthesia for total hip joint alloplasty. Fifty-three patients had general anaesthesia and in 98 cases epidural analgesia was performed. Although the statistical analysis of correlations between the fall of the arterial blood pressure and the age of patients failed to demonstrate significant differences between both types of anaesthesia the authors regard local analgesia as superior.
