A study was conducted on silver-sheathed Bi(2223) tapes undergoing uniaxial pressing, cold isostatic processing, rolling and sintering. The tapes exhibited excellent textures for press- and roll-sintering working modes. Results reveal that cold isostatic processing effectively enhances the core density. Cold isostatic processing, however, does not improve core texturing when not combined with pre-annealing.

In subjects with scoliosis the thoracic cage deformity is a complex 3D phenomenon. There is a deficiency of simple clinical methods of thorax shape evaluation. The study aimed to introduce and assess an anthropometric technique measuring transverse plane deformity of the thorax in patients with idiopathic scoliosis. Thirty scoliotic girls, aged 14.4±1.5 years, thoracic scoliosis type Lenke 1, mean Cobb 54.1±24.7°, and 30 healthy volunteers matched for sex and age were examined. Using a Martin anthropometric caliper the length of the long and the short horizontal axes of the thorax were measured at the level of the xiphoid process (upper index) and of the costal arch (lower index), both on maximum inspiration and expiration. Asymmetry index, defined as difference of the length of the long and the short axes expressed as the percentage of the short one, was calculated. The upper asymmetry index in the study group was 35.2±18.6 (inspiration) while in the control group it was 13.6±13.6, difference significant, p<0.001. The lower asymmetry index in the study group was 26.2±12.9 (inspiration) while in the control group it was 12.5±11.7, difference significant, p<0.001. In conclusion, thorax asymmetry index revealed significantly higher values in scoliotic patients. Asymmetry of respiratory movements could be measured. This simple technique may be used as a helpful tool for clinicians. [ABSTRACT FROM AUTHOR]

The increasing number of metastatic heart tumors is observed due to increasing frequency of cancer cases. Malignant melanoma, germ cell carcinomas, hematologic and lymphatic neoplasms, breast and lungs carcinomas and carcinoma of esophagus are the most often origins of metastatic tumors to the heart. In this case, patient was addmited to the Cardiology Department with suspicion of myocarditis. The only anomaly found during admission was tumor in right ventricle of the heart. After we decided of surgical treatment of the tumor, patient state worsened and she died. Autopsy confirmed our diagnose of metastatic origin of the tumor. [ABSTRACT FROM AUTHOR]

The study was performed to determine the predictive value of programmed stimulation for identification of pts with ventricular arrhythmias: 75 patients were studied by means of 24-hour ambulatory ECG (24 ECG) and programmed right (in some patients also left) ventricle stimulation at sinus and two or three pacing rates using two (standard) and three extrastimuli or burst stimulation (extensive protocol). Lown classes 0,1-3 and 4a-4b were observed in 24 ECG in 35, 14, and 26 patients, respectively. In programmed stimulation 1-6 repetitive ventricular responses (RVR) were found in 56 pts, nonsustained ventricular tachycardia in 11 and sustained ventricular tachycardia in 21 pts. High incidence of induced VT was found in pts with complex ventricular arrhythmia in 24 ECG, 81% of this group, in all but six pts only standard protocol was used. The 1-6 RVR were observed in almost 40% of pts without any arrhythmia. Conclusion; Only VT induction is a useful index for high risk patients. [ABSTRACT FROM AUTHOR]

Introduction: In scoliosis screening the angle of trunk rotation (ATR) cut off value is still debated. Static pelvic obliquity is common in growing age. It is not known whether the scoliometer values are sensitive to non-level pelvis. Objective: was to verify whether the ATR depends on functional pelvic obliquity by measuring the ATR while the pelvis was asymetrically raised with shoe lift. Methods: Study group comprised 25 girls, aged 15,6 ± 1,8 (range 13–19 years), with double major curvature (Lenke 3). Cobb angle was 60,7° ± 17,3° (range 38,0° to 93,0°) in thoracic and 54,4° ± 18,0° (range 35,0° to 92,0°) in lumbar spine. Control group comprised 25 healthy girls, aged 14,2 ± 0,9 (range 12 to 16 years). The Bunnell scoliometer readings were noted at four levels: proximal thoracic, main thoracic, thoracolumbar/lumbar and sacral. All measurements were repeated in the same subjects and at the same levels, while leveling one side of the pelvis using shoe lift. Results: The ATRs changed significantly while 1 or 2cm shoe lift was applied. The ATRs alternatively raised and lowered within adjacent spinal segments. The difference depended on shoe lift thickness and on spinal level: 1,5°–4,5° within thoracolumbar/lumbar curve; 1,2°–3,8° within main thoracic curve, and 0,7° to 2,4° within proximal thoracic curve. Conclusion: Bunnell scoliometer measurement is sensitive to a non-level pelvis. Significance: The bias in ATR measurements up to 4.5° may result from pelvis position. When using the scoliometer in school screening, the sitting forward bending position should be considered. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the following paper was Polish cultural and linguistic adaptation including adaptation of particular questions, instructions and possible answers to 2000 IKDC knee form and Lysholm's scale., Material/methods: The cultural adaptation process of this questionnaire was made according to indicators of International Quality of Life Assessment (IQOLA) project, placed in Journal of Clinical Epidemiology. Testing version (pre-final test) was carried out on 30 patients suffering from instability of a knee. Patients underwent arthroscopic reconstruction of the anterior cruciate ligament. The period from operation to filling in the questionnaires took 2 years. The questionnaire was filled up twice, at intervals from 2 days to 2 weeks., Results: We received cultural and linguistic adapted knee evaluation scales which are similar to the original version according to the psychometric proprieties such as accuracy of a single question and whole scales., Conclusions: We were able to develop a reliable, ISAKOS/ESSKA-compliant instrument for subjective knee function evaluation to be used in the population of Polish patients following arthroscopic reconstruction of anterior cruciate ligament. Polish version of IKDC 2000 questionnaire is more reliable--i.e. more useful in clinical evaluation of patients with ACL damage--than the Polish rendition of Lysholm scale.

Purpose: The number of meniscus surgeries, including partial or complete meniscectomy, has increased considerably with the progress in knee arthroscopy. An analysis of treatment results, carried out at several centres by numerous study groups, showed a development of early degenerative changes in the knees of treated patients., Methods: This study is aimed at developing a fully arthroscopic technique to treat meniscal tears by suturing and wrapping them in collagen matrix, followed by injection of liquid bone-marrow collected from the tibial proximal epiphysis, into the area of meniscal lesion., Results: In this paper, we presented arthroscopic technique for wrapping meniscal tears using the collagen matrix sutured with the Fast-Fix sutures., Conclusions: Proposed surgical technique is not straightforward to perform, but can be learned by adhering to strict arthroscopic principles. The use of collagen matrix and bone marrow aspirate from bone-marrow blood, including stem cells, creates favourable biological conditions for meniscus healing, which may increase the rate of healing.

Aim. The aim of the work was to study whether wearing a corrective brace by adolescent girls with severe idiopathic scoliosis can influence external shape of the trunk. Methods. Comparison of clinical deformity of two groups of girls matched for age and Cobb angle: group (1) of 23 girls, aged 14.9 ± 1.3 years, Cobb angle 55.0° ± 6.8°, who refused surgical treatment and have been wearing Chêneau brace for more than 6 months, compared with group (2) of 22 girls, aged 14.1 ± 1.8 years, Cobb angle 59.7° ± 14.6° never treated with corrective bracing. Clinical deformity was assessed with the Bunnell scoliometer (angle of trunk rotation ATR) and surface topography (posterior trunk symmetry index POTSI and Hump Sum HS). Results. The ATR in the primary curvature was 11.9° ± 3.4° (5°-18°) in group 1 versus 15.1° ± 5.6° (6°-25°) in group 2 (P = 0.027). The HS was 16.8° ± 3.8 versus 19.2° ± 4.6, respectively, P = 0.07. The POTSI value did not differ between groups. Conclusion. Girls with Cobb angle above 45 degrees, who have been subjected to brace treatment, revealed smaller clinical deformity of their back comparing to nontreated girls having similar radiological curvatures.

The purpose of this article is to present the current principles of comprehensive assessment and treatment of patients with myelomeningocele. We present the connection between the level of neurosegmental lesion according to modified Sharrard's classification and functional abilities of the patient. We describe lower limbs deformity typically associated with neurosegmental lesions of spina bifida at different levels (I to VI). The classification of neurosegmental lesion levels is based on an evaluation of muscle strength of individual muscle groups according to the Lovett scale.

Background: The purpose of this study is to present the current approach to and an evaluation of the results of treatment of neurogenic deformities of the hip joints in children with myelomeningocoele (MMC)., Material and Methods: The study population consisted of 210 patients with MMC admitted to the Department of Pediatric Orthopaedics and Traumatology in Poznań in the years 1970-2008. The study involved 131 hips (85 patients). The duration of follow-up was 1 to 38 years (mean 17.3 years). The clinical status of patients and treatment results were evaluated with regard to the assignment of the patient to one of 6 groups according to the modified Sharrard and Parsch classification. Radiographic evaluation included the femoral neck angle, anteversion angle, acetabular index, head-acetabular coefficient, centre-edge angle, focusing angle, and Labaziewicz distance angle. The operative treatment in Groups I-II consisted of correction of contractures. In Group III, we performed open reduction of the dislocation or subluxation, Mustard iliopsoas transfer, intertrochanteric femoral osteotomy and Dega's transiliac osteotomy, or shelf procedure. In Group IV patients, we corrected subluxations or dislocations., Results: Surgery in patients from Groups I-II was associated with a high rate of recurrence. In Group III patients, we achieved good joint stability. The transferred iliopsoas muscle was active in 70% of the patients and 65% of the patients in this group became ambulant. More beneficial functional effects were observed after operative treatment in patients from Group IV., Conclusions: In Groups I-II recurrence of the deformity was often observed. In patients from Groups III-IV, good functional outcomes were noted after comprehensive surgical treatment.

In conclusion, thorax asymmetry index revealed significantly higher values in scoliotic patients. Asymmetry of respiratory movements could be measured. This simple technique may be used as a helpful tool for clinicians.

Unlabelled: Dysfunction of the knee joint caused by injury of the anterior cruciate ligament is associated not only with mechanical joint destabilization but also damage of receptors in the ligament responsible for joint proprioception. Sensory disorders associated with damage of receptors in the ligaments may produce abnormalities in the posture control. The study aimed at evaluating postural control strategy in patients with chronic anterior cruciate ligament deficiency and determining a relationship between clinical assessment, subjective evaluation of knee joint functioning, and type of postural control., Material and Methods: Postural control with dynamic and static Riva test in one-legged position was assessed in 46 patients (6 women and 40 men), aged between 15 and 52 years (mean 32 years), in whom damage of the anterior cruciate ligament was diagnosed clinically and/or radiologically. Diagnosis was confirmed arthroscopically in all cases. Clinical evaluation was made with the aid of two subjective scales of knee ailments: Lysholm knee scale and subjective knee evaluation form IKDC 2000. Arthrometer Rolimeter by Aircast was used to measure the difference between lower limbs in anterior knee laxity during "anterior drawer" test and Lachman's test. The way of visual proprioceptive control was assessed with both dynamic (DRT) and static (SRT) Riva tests in monopodalic stance. Tests were performed with the DELOS Postural Proprioceptive System (DELOS s.r.l., Corso Lecce, Torino, Italy) in the biomechanical evaluation laboratory at Rehasport Clinic in Poznań., Conclusions: Strategy of the postural control in both dynamic and static Riva test does not allow differentiating ACL deficient leg from the mechanically stable leg. The obtained results of postural control in dynamic and static Riva test confirm significant value of knee joint mechanical stability for preservation its functional stability. Knee joint extension (hyperextension) may be one of mechanisms maintaining functional knee joint stability.

Background: In recent years pedicle screw based constructs have been increasingly used in the operative management of scoliosis. The current principles of screw placement are based on normal anatomy and therefore may not be applicable in cases of severe vertebral deformity due to torsion. The aim of this study was to evaluate the usefulness of computer tomography (CT) in preoperative planning and outcome assessment in operative management of idiopathic scoliosis with severe internal vertebral deformity., Material and Methods: The study presents our own experiences based on analysis of diagnostic and therapeutic decision-making in two patients treated surgically due to Lenke type 1A idiopathic scoliosis. Due to extensive vertebral rotation and radiological appearance suggesting thin pedicles, spine CT with 3D reconstruction was performed as part of extended preoperative work-up in order to determine screw length and diameter, the point of screw introduction and angle of introduction in three planes. Vertebral rotation was evaluated according to the Aaro-Dahlborn method. Segments were also identified where pedicle screws could not be applied due to severe rotation or small pedicle diameter., Results: Preoperative planning of screw placement enabled safe and accurate screw application, as confirmed by postoperative spine CT evidence. Satisfactory correction was achieved in both patients in the coronal and frontal planes., Conclusions: CT allows detailed preoperative planning of scoliosis surgery and identification of segments in which pedicle screws cannot be safely placed. This may lower the incidence of complications associated with inaccurate pedicle screw placement.

Injuries involving knee luxation or subluxation generally result in damage to two or three out of the four major ligaments which stabilize this joint. Past treatment of this type of multiligament injuries, consisting in 6- to 12-week immobilization in a plaster cast, does not allow for restoration of the normal, anatomical course of these ligaments. A consequence of this type of healing, which involves the formation of random scars in place of ligaments, is mechanical and functional instability of the knee joint. The goal of this article is to present a classification of multiligament knee injuries and surgical treatment options. We also present our own technique of arthroscopic, concurrent reconstruction of knee joint ligaments. The study material consisted of 20 patients who underwent surgical treatment for multiligament knee injuries in the Department of Pediatric Orthopedics and Traumatology in Poznań. We performed concurrent arthroscopic reconstruction of ACL and PCL in all 20 patients. In addition, reconstruction of the medial complex was performed in 7 patients, and lateral complex was reconstructed in another 7 patients. In three cases we stitched the medial meniscus using a Smith & Nephew FasT-Fix system, and partial menisectomy was performed in 2 patients. The details of the proposed concurrent arthroscopic ACL and PCL reconstruction are extensively discussed. One of the advantages of this operating technique is the exclusive use of autogenous ST and GR tendon grafts for reconstruction of all damaged knee joint structures. The presented operating technique makes possible the reconstruction of all damaged knee joint ligaments in less than two hours, which in turn allows the surgery to be performed in an ischemic setting using an Esmarch band around the limb.

Injuries of knee generally result in damage to major ligaments which stabilize this joint. Clendenin observed that 20% failure of ligaments of knee it is PCL rapture. A consequence of this type injuries is mechanical and functional instability of the knee joint. The goal of this article is to present our technique of arthroscopic reconstruction of PCL. We also present preliminary results of our treatment options we have applied in 14 surgery patients. The study material consisted of 14 patients who underwent surgical treatment for PCL injuries in the Department of Pediatric Orthopedics and Traumatology in Poznań. The arthroscopic reconstructions of PCL in all 14 patients have been performed by first author with the same operative technique. Knee laxity we assessed before and after PCL reconstructive surgery using arthrometer "Rolimeter" (Aircast). Knee ligament rating scales (Lyscholm and IKDC 2000) have been used to perform subjective, functional assessment of knee joint. The follow up was about 2 years. We fund statistical important improvement in all tested data (p = 0.001). The arthroscopic reconstruction of PCL with autogenic hamstring graft improves function and stability of knee joint. Endurance and size of hamstring grafts are sufficient to restore good mechanical and functional stability of knee joint.

Unlabelled: The hip joint dislocation is one of the most serious complications associated with severe type of spastic cerebral palsy in children. The natural history of this secondary problem is poorly defined: how often and why the dislocated hip joint is going to be painful. The aim of our study was to specify prevalence of hip pain in the quadriplegic spastic type of cerebral palsy children with dislocated one or two hip joints. The next purpose was to establish correlation between cartilage degenerative changes and pain appearance., Material and Method: The clinical study population consisted of cerebral palsy children, who presented a unilateral or bilateral dislocation of the hip joint, operated in Department of Pediatric Orthopedics during the period 2002 through 2005. Performed surgical procedures allowed us to evaluate degenerative changes of femoral head cartilage. In 45 operated hips (33 patients) we discovered that 33 had degenerative cartilage lesions which in 25 cases (75%) were associated with pain appearance., Results: We observed correlation between anterior location of the femoral head lesion and pain appearance, between the size of the lesion and intensity of pain complaints and also between femoral antetorsion and magnitude of pain., Conclusions: Risk factors of pain appearance in spastic dislocated hip joint are degenerative lesions on anterior face of femoral head cartilage, age of the patient, large antetorsion angle and cartilage lesion bigger than 1/4 of femoral head surface.

Background. Idiopathic scoliosis is a three-dimensional deformity of the spine and the trunk. The principle clinical method of estimation of the rotational deformity in the transversal plane of the body is the measurement of the angle of trunk rotation with a scoliometer. The aim of the study was to investigate the relationship between the angle of trunk rotation and the two radiological parameters: the Perdriolle angle of axial rotation and the Cobb angle of spinal curvature. Material and Methods. 50 children with single or double scoliosis (total of 65 curves) were examined clinically and radiologically. For each patient the angle of trunk rotation was measured with the Bunnell scoliometer, the Cobb angle and the Perdriolle angle were calculated at the a-p standing radiograph. Results. Strong positive linear correlation was found among the three parameters in thoracic curves. The correlation was less important in lumbar curves. Thoracic curves revealed superior values of the angle of trunk rotation and inferior values of the angle of Perdriolle than the lumbar curves matched for Cobb angle. Conclusions. Clinical measurement of the angle of trunk rotation with the use of a scoliometer can predict the value of the angle of the curve in thoracic scoliosis. This might replace a certain amount of radiological examination and reduce the patients' irradiation.

Background. The aim of my paper was to assess distant treatment results of patients who were treated because of hip displasia and the Chiari osteotomy was performed on those patients. Material and methods. I evaluated treatment outcomes of 27 patients who were treated at Poznan University of Medical Sciences, Clinic of Orthopedics, in 1965-1990. The Chiari osteotomy was performed on all patients for hip decenteration or hip subluxation after developmental displasia. 34 hips were evaluated (20 female and 7 male). The average age of patients was 13 years in the moment of the operation. The follow up examination was conducted 10-36 years after the Chiari osteotomy Results. After many years (30 years after the operation on the average), 37% of patients could fit into groups of very good and good results. I could assess the hips before the operation using only parameters marked on anteroposterior films. The radiographs of the hips showed displasia characterized by shallowness and steepness of the acetabulum, an increased apparent neck-corpus angle, low submersion of the femoral head in the acetabulum, and insufficient coverage of the femoral head by the acetabulum. On the radiographs taken one year after the operation I observed very good coverage of the femoral head proved by higher values (above quota) of the Wiberg angle, the Sharp angle, the Heyman and Herndon acetabulum-head indicator. I defined also a course of the osteotomy drafting an osteotomy angle, setting a degree of bone fragments displacement (medialisation), and a height of the osteotomy. Conclusions. 1. The Chiari osteotomy as a hip saving operation allows patients to function in satisfactory clinical conditions for many years. 2. When conducted correctly, the Chiari osteotomy considerably improves femoral head coverage not only in the frontal plane but also in the transverse plane. 3. Too wide osteotomy angle, more than 20 degrees , further than 50% displacement of a distal bone fragment and too low course of the osteotomy in relation to the apex of the femoral head extorted many a time by intraoperative situation, may favor worse patients clinical conditions some time later, considering acceleration of degenerative lesions confirmed before the operation.

Background. The goal of our study was to evaluate hip joints after Chiari osteotomy in computer tomography images, and to specify the field of coverage of the femoral head by the acetabulum. Material and methods. We evaluated treatment outcome in 27 patients who were treated at the Clinic of Orthopedics at the Poznan University of Medical Sciences during the period from 1965 to 1990. A Chiari osteotomy was performed on all patients for hip decentration or hip subluxation after developmental dysplasia. During the follow-up examination we evaluated the hips using CT scans taken at the greatest diameter of the femoral head and at the acetabulum level. Results. A wide area of femoral head coverage was most characteristic in the horizontal plane of the hip; the mean degree of femoral head coverage was 89.92%, which exceeded normal by 20%. On the computer tomograms taken at the greatest diameter of the femoral head the measurements were done with using the sector angles of Anada: anterior (ASA), posterior (PSA), and horizontal (HAS), as well as the anteversion angle (AA). The sector angles of Anada were within the normal range in most of these patients. Conclusions. When conducted correctly, Chiari osteotomy considerably improves femoral head coverage in the transverse plane.

Background. Dysplastic spondylolisthesis results from a congenital malformation of the vertebral processes, sometimes accompanied by spina bifida; its progression causes subluxation or dislocation in the intervertebral joints and an anterior repositioning of the entire vertebra. Isthmic spondylolisthesis, on the other hand, most often results from a spinal fissure. The body and part of the arch are dislocated, while the intervertebral joints are normal. Treatment is indicated when there is pain, neurological symptoms, or radiological signs of progression of the slippage. Material and methods. Twenty-five patients with spondylolisthesis (14 with dysplastic and 11 with isthmic) were treated surgically using in situ fusion, the Harrington method with posterolateral fusion, or transpedicular instrumentation with posterolateral fusion. Grade III or IV spondylolisthesis was reduced with traction screws. Decompression of the spinal canal and intervertebral foramina was performed in patients with neurological deficits. Results. Complete pain relief was achieved in 72% of the patients, partial in 24%, none in 4%. Neurological deficits subsided in the majority of patients. Complete recovery was achieved in 87.5% of the transpedicular patients, 72.7% of the in situ fusion patients, and 50% of the Harrington patients. Transient neurological complications occurred in 2 patients after complete reduction of the displacement, mechanical complications (hook dislocation, rod or screw failure) in 2 patients. Conclusions. Complete reduction of the slippage proved to be a riskier procedure than partial reduction.

Background. The aim of this study was a subjective evaluation of scoliosis surgery in cases of idiopathic scoliosis according to the criteria of the Scoliosis Research Society (SRS). Material and methods. Examinations based on the SRS protocol were performed for 135 patients surgically treated using Cotrel-Dubousset instrumentation with posterior spondylodesis. These were mainly patients with thoracic scoliosis, Cobb's angle 59.9+/-12.5 degrees . Results. Surgery led to correction of scoliosis to 34.6 degrees , i.e. 57.8% improvement, with a gradual decrease after compensation in the postoperative period. Posterior spondylodesis involved from 6 to 13 vertebrae. The summary outcome according to the SRS protocol was 3.79+/-0.44. The patients evaluated their level of activity the highest (4.09+/-0.9). Conclusions. Patients treated operatively with the CD technique achieve good overall outcome in terms of quality of life, as measured by the SRS questionnaire. The highest marks were given for activity, and the lowest for limited motion due to spondylodesis. The mean outcome is not significantly dependent either on the degree of scoliosis correction in the frontal plane or on the extent of the spondylodesis.

Background. The aim of our study was to assess the course and outcome in scoliosis without spondylodesis in the lumbar spine after surgical correction performed in the thoracic segment with the C-D method in patients with King's type II scoliosis (Lenke's IB, IC). Material and methods. 42 patients with idiopathic scoliosis were operated in the thoracic spine. The Cobb's angle averaged 635 +/- 9.2 degrees , together with coexistent lumbar scoliosis of 50.1 +/- 13.2 degrees . The mean observation time after surgery with the C-D method was 4.3 +/- 1.8 years. Both curvatures of correction, thoracic kyphosis, and lumbar lordosis were evaluated, as well as the thoracic-lumbar angle and shape of the lumbar scoliosis in relation to the central vertical sacral line were analyzed. Results. C-D surgery corrected thoracic scoliosis up to 28.8 +/- 8.3 degrees (54.6% scoliosis correction). Secondary correction of lumbar scoliosis not treated with C-D instrumentation made it possible to obtain a Cobb's angle of 28.9 +/- 9.7 degrees (42.3% scoliosis). Selective instrumentation and spondylodesis of scoliosis in the thoracic spine coexisted with transient decompensation of the posture on the left after surgery in 7 patients. Subsequent postsurgical observation showed the percentage of scoliosis correction in the lumbar spine decreasing to 32.7% and then to 29%. The number of patients with posture decompensation decreased to 2 cases. Conclusions. Equilibrated correction of scoliosis at the thoracic level reaching 50-60% of initial value is correlated in postsurgical observation with a small percentage of secondary decompensation of posture. The number of patients with postoperative decompensation decreases with corrections in the lumbar spine not treated with instrumentation during scoliosis surgery.
