Upper Limb after Forearm Lengthening in Patients' and Physicians' Perspective.

BACKGROUND: The goal of this study was to perform a functional (subjective) and radiological evaluation of patients who had undergone forearm lengthening by distraction osteogenesis years before. MATERIAL AND METHODS: Eleven patients with forearm shortening of various etiology were enrolled. They had undergone a total of 21 lengthening procedures. A retrospective analysis of radiological data was conducted and a subjective evaluation was accomplished by using a modified QuickDASH-9 questionnaire. RESULTS: Average bone lengthening was 3.54cm, and mean lengthening index was 40.53day/cm. Eight pa-tients answered the questionnaire at a mean of 7.8yrs after the treatment. The mean questionnaire score was 9.75pts (of 36). Four patients rated the overall function of the affected limb as improved following distraction, while 3 patients were not able to see any improvement. One patient reported that the lengthening had impaired limb function. With regard to cosmetic aspects, 4 patients reported a worsening after the lengthening procedure while 3 patients reported improvement and 1 patient did not note any changes. CONCLUSIONS: 1. Despite deformities and functional limitations, patients after forearm lengthening only occasionally suffered from moderate intensity pain. 2. The radiological outcomes were positive and the rate of complications was low. 3. The radiological outcomes did not match patient-declared functional and cosmetic results.

Cervical spine surgery in patients with diastrophic dysplasia: Case report with long-term follow-up.

Cervical kyphosis in diastrophic dysplasia (DTD) is a very dangerous deformity which may lead to compression of neural structures resulting in tetraplegia or even. Treatment of this deformity is usually surgical, but no long-term follow-up studies are presented in the literature. Authors present a case of two children with DTD who underwent anterior corpectomy due to severe cervical kyphosis. The kyphotic deformity was corrected and the normal spinal canal width was restored. The effects of the correction remained stable for respectively 6 and 10 years of the follow-up period. The unique follow-up confirms that this type of intervention leads to an effective and long lasting results. Significant cervical kyphosis in patients suffering from DTD may be treated surgically using anterior approach even in young children with a favorable and lasting results.

Severe Thoraco-lumbar Kyphoscoliosis Associated with Osteoporosis in Siblings - Case study.

The incidence of scoliosis among patients with certain systemic diseases is much higher than in the general population. Moreover, the onset of the scoliosis is in early childhood before the age of 5 and the deformity reaches extreme values. We present the clinical course of two siblings with multiple musculoskeletal deformities, osteoporosis, severe kyphoscolisis and an undiagnosed systemic disease. The onset of scoliosis was in the first months of life of both children, with a marked progression about the 8th month of life. Due to lower limb deformities, ambulation was delayed until the 5th year of life in the male sibling, and the girl remains non-ambulant. Both children had osteoporosis, which caused numerous fractures of the upper and lower limbs. Due to progression of the spinal deformity the boy underwent a posterior hemispondylodesis with instrumentation at the age of 7. The girl also underwent surgery at the age of 7, but instrumentation could not be placed successfully due to inadequate bone quality. The last follow-up to date has been at the age of 12 years for the female patient and 20 years for the male patient. The spinal deformity in the female has not progressed during the last 2-3 years. She has been on bisphosphonate therapy for two years and no new fractures have been noted. The male patient has undergone multiple surgeries for lower limb deformities and is an independent walker. His scoliosis remains stable, but a minor progression of kyphosis has been noted in the last year. The history of the two patients shows that not all early-onset deformities can be effectively treated and that osteoporosis is a crucial obstacle to this treatment.

The influence of the route of administration of gold nanoparticles on their tissue distribution and basic biochemical parameters: In vivo studies.

BACKGROUND: The gold nanoparticles (AuNP's) exhibit interesting chemical and physical properties and for this reason are intensively tested in medicine. However there is a lack of information about toxicity of those nanoparticles as well as their excretion from the body. Thus, the aim of the present study was to investigate the influence of the route of administration of gold nanoparticles to rats on their distribution in tissues and excretion rate. METHODS: The experiment was carried out on male Wistar rats. The colloidal gold suspension containing 0.3619 mg of particles per milliliter, was administered per 1 kg of body weight. Serum levels of alanine aminotransferase, aspartate aminotransferase, total cholesterol, triglycerides, glucose and ferric reducing ability of plasma were measured in all investigated animals. RESULTS: It was shown that after oral administration only a small amount of AuNPs was absorbed. In addition, excretion of the metal during consecutive days after po or iv administration was examined. Moreover, the impact of AuNPs on some biochemical parameters 3 days after intravenous administration was studied. It was shown that the AuNPs are mainly cumulated in the liver, lungs and in spleen after iv administration and only slightly removed from the body in urine and feces. CONCLUSION: Accumulation of those nanoparticles effect in increases of FRAP and glucose level up to 27% and 73%, respectively. This in turn suggests that iv administration of AuNPs may effect in serious medical complications. On the other site, the accumulation in the liver of about 50% of introduced particles to the rats body is promising for phototherapy and it opens "door" for drug transport to this organ.

Anterior fixation of thoracolumbar traumatic spinal injuries.

BACKGROUND: Traumatic spinal fractures require surgical treatment to restore the anatomical curvatures of the spine and release the nervous structures. However, uniform management guidelines have not been established and thus the literature includes papers focussing only on the posterior techniques as well as those assessing the anterior or anteroposterior approaches. This paper presents the outcomes of the treatment of spinal fractures with anterior and anteroposterior fixation. MATERIAL AND METHODS: The study enrolled 48 patients. The age of the patients at the time of injury was 36.8 years on average and the mean follow-up period was 3.8 years. All the fractures were unstable and caused stenosis of the spinal canal lumen. We used anterior or combined anterior and posterior approaches with a titanium implant in all the cases. Radiological assessment involved determination of the monosegmental and bisegmental Cobb angle, and the neurological status was evaluated according to the Frankel classification. RESULTS: The mean post-traumatic monosegmental angle was -17.1°, compared to -9.1° post-operatively and -9.2° at followup. The bisegmental angle was -12.7° at baseline, -7.9° post-operatively, and -8° in the follow-up period. Neurological assessment showed no neurological deficits in 27 patients while 2 persons had complete limb paralysis and the other 19 patients had various degrees of neurological deficits. The last follow-up examination did not show any improvement with respect to the neurological status of the patients with complete paralysis. However, an improvement of at least 1 Frankel group was noted in 15 patients with partial neurological deficits. CONCLUSIONS: 1. The most common causes of traumatic spinal injuries are falls from a height and road accidents. 2. fractures occur most often at the thoracolumbar junction of the spine. 2. Anteroposterior fixation with release of the spinal canal and spinal fusion is a beneficial treatment method. 3. Apart from vertebral body mesh, treating lumbar spine fractures requires the additional use of vertebral body screws or transpedicular posterior fixation. 4. Anterior fixation ensures the restoration of the physiological curvatures of the spine and stabilizes the spine until a complete bone union is achieved, preventing the loss of correction during the follow-up period.

Comparison of Postoperative Period in Patients with Pectus Excavatum Treated with Nuss Technique and Ravitch Technique.

BACKGROUND: Pectus excavatum (PE) is the most common defect of the chest wall. Surgery for PE can be performed with an open or endoscopic technique. The choice of the surgical approach influences the postoperative course. The aim of the paper is to analyze the postoperative period in two groups of patients treated for PE. Group 1 consisted of patients who underwent endoscopic surgery, and Group 2 was composed of patients who underwent open surgery. A secondary aim is to compare the surgical outcomes between the two groups. MATERIAL AND METHODS: The study group consisted of 40 patients treated in a single centre that uses a uniform postoperative analgesic protocol. The duration of surgery, blood loss, duration of hospital stay, complications, pain intensity and consumption of opioid and non-opioid analgesics were analyzed. The mean duration of follow-up was 9 months (6 -25 months). RESULTS: Age at surgery, weight and height did not differ between the groups. In Group 1 the duration of surgery and blood loss were lower than in Group 2. In Group 1 complications occurred in 25% of the patients. Pain intensity was higher in Group 1 (4.23 vs. 3.67), as was the consumption of strong opioids (0.52 mg/kg body weight vs. 0.25 mg/kg body weight). Subjective evaluation was satisfactory in 85% of the patients in Group 1 and 90% in Group 2. CONCLUSIONS: 1. Both techniques led to a satisfactory outcome. 2. The duration of surgery and blood loss were higher in the open surgery group, but pain intensity and consumption of strong analgesics were higher among the patients treated with the endoscopic technique. 3. Preparation for surgery should involve planning appropriate analgesic treatment in the post-operative period.

[Long-term consequences of resection of 1/3 proximal epiphysis of child's right tibia--a case study]. / Odlegle nastepstwa resekcji 1/3 nasady blizszej kosci piszczelowej prawej u dziecka--opis przypadku.

Authors report a case of a patient with varus deformity of right knee, caused by wide resection of proximal metaphysis and epiphysis of right tibia. Afore mentioned procedure led to loss of right knee joint integrity, with its lateral instability, shortening, and axis deviation of right tibia. Surgical treatment of this complications was performed in several stages and took about 5 years, starting from temporal, lateral hemiepiphysiodesis of proximal tibial epiphysis, subacute epiphysiolysis of proximal tibial epiphysis and high valgus tibia osteotomy, at the end finished with medial tibia condyle reconstruction with autogenic graft and osteoconductive substances. The proper mechanical and anatomical axis of the right limb, with full stability and movement of right knee was achieved after those surgeries. The process of treatment of lower extremity axis deviation takes long time, frequently involves several surgeries and needs firm cooperation between doctor and patient.

[Return to physical activity and duration of exemption from physical education classes after mild and moderate head injury in children at school age]. / Powrót do aktywnosci fizycznej a dlugosc trwania zwolnien z zajec wychowania fizycznego po lekkim lub sredniociezkim urazie czaszkowo-mózgowym u dzieci w wieku szkolnym.

GOAL: An attempt to explain the correlation between exemption from physical education classes at school, the length of their duration and the return to physical activity of children with mild and moderate head injury. MATERIAL AND THE METHOD: 55 patients the age of 7 to 17 years treated in two hospital centers due to mild and moderate head injury. The results were interpreted basing on an author's survey conducted among respondents in 1-2 weeks after the injury and after 12 weeks from sustained head injury. The survey was also conducted in the control group of children without head injury (55 children, age 7-17 years). RESULTS: Exemption from physical education classes at school concerned 89% of respondents and lasted on average 9.7 weeks. Only 33% of respondents did not participate in any activity during the exemption. The main problems reported and related to the head injury which correlate with physical exertion were headache, dizziness and frequent feeling of fatigue. CONCLUSIONS: Prolonged duration of exemption from physical education classes at school in the light of this research seems unnecessary.

[Polish nomenclature of lumbar disc disease]. / Polskie mianownictwo choroby dyskowej Iedzwiowego odcinka kregoslupa.

Lumbar disc herniation is one of the most common damage of musculoskeletal system. The incidence of pain of lumbosacral spine is estimated approximately on 60-90% in general population, whereas the incidence of disc herniation in patients experiencing low back pain is about 91%. Despite the high incidence and uncomplicated pathogenesis of disc disease there is a problem with the nomenclature. In the vast majority of cases, the naming confusion stems from ignorance of the etiology of low back pain. Different terminologies: morphological, topographical, Radiological and Clinical are used interchangeably. In addition, diagnosis is presented in a variety of languages: Polish, English and Latin. Moreover, the medical and traditional language are used alternately. The authors found in Polish literature more, than 20 terms to describe lumbar disc herniation. All of these terms in the meaning of the authors are used to determine one pathology--mechanical damage to the intervertebral disc and moving the disc material beyond the anatomical area.

[Methylprednisolone- acute spinal cord injury, benefits or risks?]. / Metyloprednizolon ­ ostre urazy rdzeniakregowego, korzysci czy zagrozenia ?

Methylprednisolone is a synthetic glucocorticoid with a potent and long-acting anti-inflammatory, antiallergic and immunosuppressant. Its mechanism of action of methylprednisolone is the result of many cellular changes. Methylprednisolone is used in many diseases, such as rheumatic diseases, autoimmune diseases, allergic, anaphylactic shock, asthma. Methylprednisolone was also used in patients with spinal cord injury, in order to minimize neurological damage. While in the above mentioned fields of medicine is undeniable role of methylprednisolone, whereas its use in the treatment of traumatic spinal cord injury within the last few years raises a lot of controversy, and in most cases, the side effects of its use outweigh the potential benefits. 

Spine deformities in patients with Ehlers-Danlos syndrome, type IV - late results of surgical treatment.

BACKGROUND: Spinal deformities in Ehlers-Danlos syndrome are usually progressive and may require operative treatment. There is limited number of studies describing late results of surgery in this disease. METHODS: This is a retrospective study of the records of 11 patients with Ehlers-Danlos syndrome type IV, treated surgically between 1990 and 2007. All patients underwent surgical treatment for spinal deformity. Duration of operation, type of instrumentation, intraoperative blood loss, complications and number of additional surgeries were noted. Radiographic measurement was performed on standing AP and lateral radiographs acquired before surgery, just after and at final follow up. RESULTS: The mean follow up period was 5.5 ± 2.9 years (range 1-10 years). The mean preoperative thoracic and lumbar curve were 109.5 ± 19.9° (range 83° - 142°) and 75.6 ± 26.7° (range 40° - 108°) respectively. Posterior spine fusion alone was performed on 6 patients and combined anterior and posterior fusion (one- or two stage) on 5 cases. Posterior segmental spinal instrumentation was applied with use of hooks, screws and wires. The mean postoperative thoracic and lumbar curve improved to 79.3 ± 16.1° (range 56° - 105°) and 58.5 ± 27.7° (range 10° - 95°) respectively, with a slight loss of correction during follow up. The average thoracic and lumbar correction was 26.4 ± 14.9% (range 5.3 - 50.4%) and 26.3 ± 21.2% (range 7.9 - 75%). Postoperatively, the mean kyphosis was 79.5 ± 40.3° (range 21° -170°), and lordosis was 50.8 ± 18.6° (range 20° -79°). Hyperkyphosis increased during follow up while lordosis remained stable. Mean Th12-L2 angle was -3.5 ±9.9° (range -19° - 15°) postoperatively and did not change significantly during follow up. CONCLUSIONS: Huge spinal deformities in patients with Ehlers-Danlos syndrome require complex and extensive surgery. There is a big risk of sagittal imbalance in this group.

Diastrophic dysplasia in a seven-year-old girl. Case study.

Diastrophic dysplasia is a rare genetic disorder characterised by short limbs and deformities of several joints occurring in conjunction with abnormal spinal curvatures, impaired metacarpal modelling and so-called hitchhiker thumbs. The condition is progressive and leads to considerable physical disability. It continues to constitute a challenge for doctors as the outcomes of corrective orthopaedic surgery are limited. The aim of this paper is to present the course of diastrophic dysplasia in a 7-year-old girl who also experienced cervical spine luxation with signs of compression of the spinal cord and carotid arteries. We describe deformities of the motor organs present in the patient and characteristic of diastrophic dysplasia, and the findings of specialised accessory investigations. The example of evaluation for bone disorders is used to draw attention to the principles of interpretation of densitometry measurements in a patient with impaired somatic development.

[Scoliosis in Rett syndrome--own experience]. / Skolioza u chorych z zespolem Retta--doswiadczenia wlasne.

Rett syndrome (RS) is a rare genetic disorder affecting only girls. The prevalence is 1:15000. The most characteristic features of RS are: lack of development, wringing of the hands. Musculoskeletal system is also affected and scoliosis remains the biggest challenge. Aim of paper is to describe the curve progression pre-operatively, course of surgery and finally radiological and subjective results of treatment. Postoperative follow-up was 3.1 year. We describe a series of 9 girls with RS and scoliosis treated surgically in single Institution. All presented scoliosis that increased with a rate of mean 16.1 degrees per year. Preoperatively curves ranged from 52 degrees up to 120 degrees Cobb angle. Curve pattern was similar in all cases, long thoraco-lumbar curve with thoracic hyperkyphoisis. All girls underwent surgery. Posterior fusion with Luque-Galvestone technique, posterior hybdrid fusion or anterior fusion was performed depending on the degree of scoliosis. Surgery and postoperative period were uneventful. Mean blood loss was 650 ml; mean obtained correction was 38%, with minimal correction loss at final follow-up. No additional surgery was required. Most caregivers were subjectively satisfied with surgery. Scoliosis in RS patients is progressive, with a high annual rate. Surgery should be performed I cases of curves of 40-50 degrees in specialized centers. The procedure is safe, and does not affect general condition nor deteriorate neurological status. In non-ambulant patients fusion should be carried out to the pelvis.

Treatment of idiopathic scoliosis exceeding 100 degrees - comparison of different surgical techniques.

BACKGROUND: The treatment of scoliosis exceeding 100 degrees remains a challenge. Anterior fusion only may lead to low correction and screw plowing, posterior fusion only may cause the cranckshaft phenomenon in skeletally immature patients. Two-stage surgery is advocated, comprising anterior release and posterior fusion. MATERIAL AND METHODS: The aim of the paper is to compare treatment outcomes in patients with a >100% primary curve treated between 1984 - 2004 with one of the following techniques: halo-femoral traction with posterior fusion (Group I; n=124 patients), anterior release with halo-femoral traction and posterior fusion (Group II; n=32), single stage anterior release and posterior fusion (Group III; n=20), and posterior fusion only (Group IV; n=19). Correction and loss of correction were assessed radiologically. Additional surgical procedures and the presence of complications were also recorded. The fusion techniques were compared. Mean post-operative follow-up duration was 3.9 years, ranging from 2 to 15.3 years. RESULTS: Correction was highest in Group II and Group III (52.7% and 51.7%, respectively); vs. Group I and Group IV (45.8% and 38.7%, respectively). The loss of correction at final follow-up was lowest in Group II and Group III (2% and 3.3%), and highest in Group I and Group IV (6.4% and 15.6%, p<0.05). In all groups, the use of derotational instrumentation increased correction (59.7% C-D vs. 37% Wisconsin vs. 24.5% Harrington-Luque) and decreased loss of correction (4% C-D vs. 5% Harrington-Luque vs. 28% Wisconsin). Rates of neurological complications were similar in all groups; no persistent deficits were noted. CONCLUSIONS: Anterior release with halo traction and posterior fusion is the optimal treatment of severe scoliosis. If halo traction is contraindicated, single stage anterior release and posterior fusion should be performed. Contemporary instrumentation techniques result in higher correction rates and better curve stability.

Retrospective study of two-stage surgery in the treatment of scoliosis exceeding 100 degrees - assessment including spinal balance evaluation.

BACKGROUND: Scoliosis exceeding 100 degrees remains an important problem in spinal orthopaedics. The choice of an optimal surgical technique is crucial, not only because of the degree of correction needed, but also because of the need to minimize the number of complications and avoid imbalance after surgery. The aim of this work is to analyse the outcomes of a two-stage surgical regimen for scoliosis exceeding 100 degrees consisting of anterior release, cranio-femoral traction, and posterior fusion with derotational instrumentation. MATERIAL AND METHODS: Twelve patients with thoracic scoliosis (7 females and 5 males) were assessed retrospectively. The mean curve angle before surgery was 129 degrees. All patients underwent a two-stage procedure consisting of anterior release followed by 10-14 days of cranio-femoral traction and posterior fusion with derotational instrumentation. Mean age at surgery was 19 years. The mean follow-up period was 5 years. Radiological evaluation was based on postero-anterior and lateral radiographs. RESULTS: Mean curve correction was 44% and this result was stable during the follow-up period. Thoracic kyphosis did not change significantly after treatment, remaining at 61 degrees on average. Coronal decompensation was noted in 4 patients before surgery and one of the four after treatment. The Th1-midline distance improved significantly, as did the Th12-L2 angle on lateral radiographs. There were no neurological complications. CONCLUSION: Two-stage treatment of very severe scoliosis enables stable correction with some improvement of spinal balance in both the coronal and sagittal plane.

Does instrumentation removal cause curve progression in patients with adolescent idiopathic scoliosis?

Adolescent idiopathic scoliosis (AIS) is usually instrumented using a posterior approach. Hardware removal may be performed for specific clinical reasons. Little data is available on whether removal influences curve magnitude. The aim of the paper is to evaluate the impact of instrumentation removal on curve progression, and the safety and efficacy of the procedure. We analyzed 59 patients who underwent instrumentation removal. Curve types, reasons for removal, period between procedures, and Cobb angles: at baseline, immediately after correction, after removal and in follow-up were evaluated. Clinical symptoms were also assessed. The mean follow-up period after instrumentation removal was 2.2 years (1-5 years). The mean age at primary surgery was 14.5 years (12-25 years) and the mean Cobb angle after surgery was 24.9 degrees in the thoracic spine, and 17.5 degrees in the lumbar spine. The period between procedures was 46.6 months (11-192 months). The reasons for removal were: fistula (38.9%), pain (35.6%), rib hump removal (13.6%), and hardware failure (11.9%). At the final follow-up, mean thoracic curve was 35.4 degrees and lumbar curve was 26.2 degrees , corresponding to 13.3% and 17.5% curve progression after removal, respectively. Patients with infection had the highest loss of correction (21%). In symptomatic patients, pain subsided in 70% of the cases. In cases of hardware removal > 2 years after fusion, loss of correction was lower than in the < 2 years group. The course of surgery was relatively uneventful.

New criteria of radiological assessment of treatment outcomes in idiopathic scoliosis.

INTRODUCTION: The aim of surgical treatment in idiopathic scoliosis is correction, solid fusion and restoration of normal sagittal alignment of the spinal curves. The goal of this paper is to formulate a new uniform approach to evaluation of treatment outcomes in idiopathic scoliosis patients, considering not only the degree of correction but also coronal and sagittal balance. MATERIAL AND METHODS: A retrospective analysis was performed of radiographs of 150 patients with idiopathic scoliosis (136 females and 14 males). The mean thoracic curve was 56.1 degree and mean lumbar curve was 51.2 degree. All patients underwent posterior fusion with derotational instrumentation. The follow-up period was 3.7 years. The authors used their own radiological criteria for assessing surgical treatment outcomes separately for the coronal and sagittal planes and in both planes collectively. RESULTS: The degree of correction achieved was 61.8% in the thoracic spine and 66.6% in the lumbar spine. Good coronal plane outcomes were achieved in 97 patients (65%), and poor outcomes were seen in 53 (35%) cases. Good sagittal plane outcomes were achieved in 112 cases (75%), with poor outcomes in 38 (25%) patients. Good composite outcomes were noted in 76 cases (51%), and poor composite outcomes were achieved in 24 patients (16%) with ambiguous outcomes in 50 (33%). Apical vertebral translation in lumbar spine >or=35 mm, L4 angle >10 degree and lower fusion end at the L3 level are risk factors for a poor outcome. CONCLUSIONS: The proposed system for evaluation of radiological outcomes provides unequivocal results, not only accounting for the degree of correction, but also enabling quantitative evaluation of spinal balance in the coronal and sagittal planes.

[Regeneration formation index--new method of quantitative evaluation of distraction osteogenesis]. / Wspólczynnik powstawania regeneratu--nowa metoda ilosciowej oceny przebiegu dystrakcyjnej osteogenezy.

INTRODUCTION: One of the most common techniques for limb lengthening is the Ilizarov method. The course of osteogenesis is usually monitored using classic X-ray in this way determining the moment of fixator removal. Classic x-ray evaluation is subjective and therefore errors may easily be encountered. New techniques for objective and quantitative evaluation of radiologic documentation are needed. Computer assisted image analysis offers this possibility. AIM OF PAPER: Aim of this prospective study is to determine a quantitative, measurable method of regenerate description during distraction osteogenesis, based on classic radiography and computer assisted image analysis. MATERIAL AND METHODS: Material consists of 40 patients, in whom long bone lengthening procedures were performed. Altogether 40 lengthening were performed, 16-femur, 20-tibia, 4-humeral. Radiographic data, obtained in standard conditions, were than analyzed digitally. A mathematical bone model was created and later compared with obtained regenerate images. Computer processing lead to determining a new value, called regeneration formation index (RFI). For the model bone, the value is one. RESULTS: Average femur lengthening was 5.4 cm, tibia lengthening was 5.6 cm, and humeral 8.0 cm. During distraction osteogenesis the RFI, at the end of distraction phase, and the beginning of stabilization phase reached the lowest values, to increase steadily with the progress of osteogenesis, finally at the end of stabilization phase reaching the original values. The pace of RFI increase correlated with the presence of potential complications that require surgical treatment. CONCLUSION: Quantitative evaluation of regenerate using the regeneration formation index allows to precisely analyze the course of distraction osteogenesis, particularly to precisely estimate the timing of fixator removal and avoid complications.

Results of simple excision technique in the surgical treatment of symptomatic accessory navicular bones.

INTRODUCTION: Accessory navicular bones might cause not only cosmetic problems but also be a reason of discomfort and pain. In case of inefficient conservative treatment symptomatic accessory naviculars are treated surgically. AIM OF PAPER: Presentation of results of simple excision of symptomatic accessory navicular. MATERIAL AND METHODS: Material consists of 22 patients (34 feet), 17 women and 5 men, treated surgically between 1992 and 2006. Mean age at surgery was 14.1 years (9-22 years). Accessory navicular type I was present in 5 feet (14.7%), type II in 17 (50%) and type III-in 12 (35.3%). Main symptom was localized pain on the medial arch of the foot, in the height of navicular bone. Surgery consisted of simple accessory navicular excision and if needed partial resection of navicular bone. The mean follow-up period was 5.6 years (1-13 years). We analyzed: intensity of pain (VAS score system), daily and sport activity. Subjective results were analyzed using a questionnaire. RESULTS: The questionnaire was returned from 21 patients: 9 patients had total pain relief, 11 considerable and one patient had persistent pain. Mean VAS results before surgery was 5.9 and 1.7 after surgery. Only one patient required analgesics occasionally. Complications were present in two patients (6.1%). All active patients returned to their sport activities. CONCLUSION: Surgical treatment of symptomatic accessory navicular by simple excision technique gives satisfying results, surgery is minimally traumatic and risk of complications low.

[Use of VEPTR (Vertebral Expandable Prosthetic Titanium Rib) device in the treatment of congenital spine and thorax deformities]. / Zastosowanie systemu implantów VEPTR (Vertebral Expandable Prosthetic Titanium Rib) w leczeniu wrodzonych deformacji kregoslupa i klatki piersiowej.

UNLABELLED: Congenital spine and thorax deformities are an interdisciplinary clinical problem. Apart from trunk deformity they may lead to respiratory or cardiovascular insufficiency. Surgical treatment should be implimented as soon as possible in order to improve posture, balance and further development. This treatment should not impair further growth of the young spine. This is possible with the VEPTR device. AIM OF PAPER: Aim of paper is presentation of initial results of surgical treatment of congenital spine deformities with the VEPTR system. MATERIAL, METHODS: We treated 3 patients, aged 5 to 14. All had severe congenital spine and thorax deformities. The VEPTR device was implanted in the following configurations: rib-rib in two patients and spine-rib in one patient. We evaluated: Cobb angle of the main curve, spine balance, respiratory function before and after surgical treatment. Followup was 12 months. RESULTS: Posture and balance of the spine improved in all patients. Curve correction was from 10% to 71%. In one patient with initial respiratory insufficiency symptoms subsided gradually. CONCLUSION: VEPTR device is indicated in treatment of severe congenital deformities of the spine and thoracic cage. It improves patients' posture, changes the shape of thorax wall and consecutively improves respiratory function and further development.
