Relationship between the hip range of motion and functional motor system movement patterns in football players.

Background: The aim of this study was to determine the hip range of motion and the movement patterns of football players assessed with an aid of a Functional Motor Systems test, and to find an association between these parameters and the risk for hip joint injury.

Methods: The study included 50 men aged between 16 and 20 years: 25 footballers and 25 age- and body mass index-matched controls. The hip ranges of motion (flexion, extension, internal and external rotation, adduction and abduction) were determined, and the movement patterns were evaluated with the tests from the Functional Motor Systems battery.

Activity and Quality of Life after Total Hip Arthroplasty.

Background: Coxarthrosis is a chronic musculoskeletal condition that causes severe pain and considerable limi-tation of the patient's motor performance. Total hip arthroplasty is one of the most common and effective methods used in the treatment of advanced degenerative changes. The aim of the present study was to evaluate the activity and quality of life of patients after unilateral total hip arthroplasty.

The role of vasculature in bone development, regeneration and proper systemic functioning.

Bone is a richly vascularized connective tissue. As the main source of oxygen, nutrients, hormones, neurotransmitters and growth factors delivered to the bone cells, vasculature is indispensable for appropriate bone development, regeneration and remodeling. Bone vasculature also orchestrates the process of hematopoiesis.

Bone remodeling in the context of cellular and systemic regulation: the role of osteocytes and the nervous system.

Bone is a dynamic tissue that undergoes constant remodeling. The appropriate course of this process determines development and regeneration of the skeleton. Tight molecular control of bone remodeling is vital for the maintenance of appropriate physiology and microarchitecture of the bone, providing homeostasis, also at the systemic level.

Treatment of reverse obliquity intertrochanteric fractures.

Background: Unstable intertrochanteric fractures of the hip, especially reverse oblique fractures are a serious problem in traumatology, as there is no standard method of treatment and inadequate treatment carries a significant complication rate. To assess the surgical treatment results of reverse oblique trochanteric fractures.

Material/methods: Between 1997-2010, 389 patients with intertrochanteric fractures were treated.

Kinetic and kinematic characteristics of natural velocity gait in anterior cruciate ligament-deficient patients.

This study evaluates changes in the knee following anterior cruciate ligament (ACL) injuries by presenting the kinematic characteristics of the ankle and hip joints and the pelvis, and assessing the dynamic forces applied by knee joint muscles under isokinetic conditions to identify compensatory mechanisms. Seventeen ACL-deficient males, 16-47 years of age, participated in the study, and measurements were taken an average of 24.4 months after their injuries occurred.

Evaluation of the kinematic parameters of normal-paced gait in subjects with gonarthrosis and the influence of gonarthrosis on the function of the ankle joint and hip joint.

The aim of the study was to assess the variability of parameters characterising the gait of persons suffering from degenerative changes of the knee joint and their influence on the ankle and hip joints. The values of the angular changes in the knee, ankle and hip joints in the three planes of motion were assessed. Locomotion tests were performed on 27 persons, aged between 60 and 74, using Vicon 250, the three-dimensional analysis system.

Ectopic bone formation after treatment with colchicine.

We followed changes occurring within bone tissue and marrow cells during the process of colchicine-induced ectopic bone development and its resorption inside the marrow cavity of the rat tibia. To stimulate ectopic bone formation male Wistar rats were i.p injected with 0.

[Analysis of kinematic parameters of normal-paced gait in subject after posterior cruciate retention and substitution total knee replacement--leading article].

The main goal of this study was to estimate the variability of gait parameters (angular changes) in patients after cruciate-retaining and cruciate-substituting total knee arthroplasties. Angular changes of the knee joint in three planes were taken into consideration. The three-dimensional analysis of locomotion pattern was carried out on 18 patients aged 60-74, using the Vicon system.

[The three-dimensional pattern of the pelvis movement in standarized gait cycle in patients before and after knee arthroplasty--leading article].

The main goal of this study was to estimate the influence of knee arthroplasty on angular changes of pelvis movement in three planes. The three-dimensional analysis of locomotion was carried out with 13 patients afer total knee replacement aged 47-74, using Vicon system. The first examination took place before knee operation and the second examination 6 months after arthroplasty.

Three-dimensional pattern of knee movement in patients with gonarthrosis.

Background: The main goal of this study was to estimate the variability of gait parameters in patients diagnosed with arthroplasty of the knee joint. Angular changes of the knee joint in three planes, and spatio-temporal parameters of gait were analysed.

Materials And Methods: A three-dimensional analysis of locomotion patterns was carried out using the Vicon 250 system in 33 patients aged 48-74.

[Total hip replacement in young patients with use of MAYO prosthesis--early result of treatment].

Authors presented the results of the treatment of osteoarthritis of the hip with MAYO endoprosthesis. The paper is focused on young adults. 34 operations in the 2000-2006 were performed.

Treatment of femoral shaft union disturbances with intramedullary nailing. Treatment failure.

Background: The paper contains an analysis of the treatment outcomes of intramedullary nailing for femoral shaft non-union.

Materials And Methods: Twenty-two patients were treated between 1999 and 2005 with locked intramedullary nailing for femoral shaft non-union. The average age was 38.

Incorrect osteosynthesis as a cause of bone union disturbances.

Background: Treatment of bone union disturbances is one of the most difficult therapeutic challenges in any orthopaedic and trauma department.

Material And Methods: An analysis of causes of bone union disturbances in a series of 136 patients treated between 1999 and 2005 at the Orthopaedics and Traumatology Department of Jagiellonian University's Collegium Medicum is presented with particular regard to the type of primary stabilisation.

Results: An inappropriate primary stabilisation technique was the cause of bone union disturbances in nearly all of the patients.

[Interlocking intramedullary nail with reaming of bone marrow cavity in treatment of tibia and femur pseudarthrosis].

The aim of this paper was to assess the results of treatment of pesudoarthrosis of the tibia and femur with reamed interlocked intramedullary nailing. A group of 17 patients with pseudoarthrosis of long bones were treated. Pseudoarthrosis were located in 10 cases in the tibia and in 7 cases in the femur.

Three-dimensional model of bone marrow stromal cell culture.

In a hematopoietic microenvironment in vivo, spatial organisation of hematopoiesis is possible due to the existence of a three-dimensional framework, the main part of which is formed by a branching population of stromal cells. Most of the previous in vitro studies, concerning long-term bone marrow cultures, were based on a previously prepared, flat adherent layer of stromal cells. There are only few reports concerning the three-dimensional growth pattern of the bone marrow stroma.

[Monitoring of the early stages of bone healing process based on serum osteocalcin level changes].

The aim of this paper was assessment of utility of serum osteocalcin levels in monitoring early stages of bone healing and early detection of bone healing disorders. Serum osteocalcin level and alkaline phosphatase activity was assessed with acute long bone fractures and with delayed bone union and pseudoarthroses. 25 patients underwent the trial.
