Mobility of the lumbo-pelvic-hip complex (spinopelvic mobility) and sagittal spinal alignment - implications for surgeons performing hip arthroplasty. Arch Orthop Trauma Surg 2024; 144:1945-1953. [PMID: 38554202 DOI: 10.1007/s00402-024-05241-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 02/17/2024] [Indexed: 04/01/2024]
Abstract
INTRODUCTION The optimal positioning of the hip prosthesis components is influenced by the mobility and balance of the spine. The present study classifies patients with pathology of the spino-pelvic-hip complex, showing possible methods of preventing hip dislocations after arthroplasty. HYPOTHESIS Hip-Spine Classification helps arthroplasty surgeons to implant components in more patient-specific position. MATERIALS AND METHODS The group of 100 patients treated with total hip arthroplasty. Antero-posterior (AP) X-rays of the pelvis in a standing position, lateral spine (standing and sitting) and AP of the pelvis (supine after the procedure) were analyzed. We analyzed a change in sacral tilt value when changing from standing to sitting (∆SS), Pelvic Incidence (PI), Lumbar Lordosis (LL) Mismatch, sagittal lumbar pelvic balance (standing position). Patients were classified according to the Hip-Spine Classification. Postoperatively, the inclination and anteversion of the implanted acetabular component were measured. RESULTS In our study 1 A was diagnosed in 61% of all cases, 1B in 18%, 2 A in 16%, 2B in 5%. 50 out of 61 (82%) in group 1 A were placed within the Levinnek "safe zone". In 1B, 2 A, 2B, the position of the acetabular component was influenced by both the spinopelvic mobility and sagittal spinal balance. The mean inclination was 43.35° and the anteversion was 17.4°. CONCLUSIONS Categorizing patients according to Hip-Spine Classification one can identify possible consequences the patients at risk. Pathology of the spino-pelvic-hipcomplex can lead to destabilization or dislocation of hip after surgery even though implanted according to Lewinnek's indications. Our findings suggest that Lewinnek safe zone should be abandoned in favor of the concept of functional safe zones.

Is the Synovium the First Responder to Posttraumatic Knee Joint Stress? The Molecular Pathogenesis of Traumatic Cartilage Degeneration. Cartilage 2023; 14:473-481. [PMID: 36799236 PMCID: PMC10807737 DOI: 10.1177/19476035231155630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 01/19/2023] [Accepted: 01/21/2023] [Indexed: 02/18/2023] Open
Abstract
OBJECTIVE The aim of this study was to evaluate if a similar catabolic and inflammatory gene pattern exists between the synovium, hyaline cartilage, and blood of patients with the knee joint tissues and if one precedes the other. DESIGN A total of fifty-eight patients (34 females and 24 males) with a mean age of 44.7 years (range, 18-75) underwent elective knee arthroscopy due to previously diagnosed pathology. Full blood samples were collected preoperatively from synovium and cartilage samples intraoperatively. Real time PCR with spectrophotometric analysis was performed. Following genes taking part in ECM (extracellular matrix) remodeling were selected for analysis: MMP-1, MMP-2, MMP-8, MMP-9, MMP-13, MMP-14, ADAMTS-4 (Agg1) and ADAMTS-5 (Agg2) proteases, TIMP-1, and TIMP-2 - their inhibitors - and IL-1 and TNF-α cytokines. RESULTS Analysis revealed a strong and significant correlation between gene expression in synovial and systemic blood cells (p <0.05 for all studied genes) with ADAMTS-4, ADAMTS-5, IL-1, TNF-α and TIMP-2 expression most positively correlated with an R>0.8 for each. An analysis between chondrocytes and systemic blood gene expression shown no significant correlation for all genes. Bivariate correlation of International Cartilage Repair Society grading and genes expression revealed significant associations with synovial MMP-1, MMP-2, MMP-8, MMP-9, IL-1, TNF-α and TIMP-2. CONCLUSION We suggest that the synovial tissue is the first responder for knee joint stress factors in correlation with the response of blood cells. The chondrocyte's genetic response must be further investigated to elucidate the genetic program of synovial joints, as an organ, during OA development and progression.

An Analysis of the Preoperative Factors, Spinopelvic Mobility and Sagittal Spinal Alignment in Pre-THA Patients. J Clin Med 2023; 12:5594. [PMID: 37685661 PMCID: PMC10488904 DOI: 10.3390/jcm12175594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 08/24/2023] [Accepted: 08/25/2023] [Indexed: 09/10/2023] Open
Abstract
Hip arthroplasty is a very effective medical procedure. The optimal positioning of the components and the functioning of the endoprosthesis are influenced, among other things, by the mobility and balance of the spine. The aim of the study was to analyze the factors influencing the mobility of the lumbar-pelvic-iliac complex (spinopelvic mobility) together with the assessment of sagittal spinal alignment in patients prior to THA (total hip arthroplasty). Patients who underwent hip replacement surgery due to advanced osteoarthritis of the hip were enrolled in the study (n = 103). The sociodemographic characteristics, BMI, radiological advancement of the degenerative disease, quality of life, and range of joint mobility were completed using a proprietary questionnaire, the EQ-5D-5L questionnaire, and a clinical examination. X-ray images were analyzed: AP of the pelvis standing up, lateral of the spine standing and sitting. Key parameters were measured as ∆SS-change in sacrum angle value when changing from standing to sitting position and pelvic incidence (PI)-lumbar lordosis (LL) mismatch-sagittal lumbar pelvic balance measured in standing position. The patients were assigned to the appropriate groups according to the Hip-Spine Classification: normal group: 1A (n = 65; 63.1%), abnormal groups: 1B (n = 17; 16.5%), 2A (n = 16; 15.5%), 2B (n = 5; 4.9%). A correlation was shown between the abnormal groups and the individual components of PROMs in the scope of the self-service and normal activities categories (EQ-5D and EQ-VAS). However, the strength of the relationship turned out to be moderate, and the remaining components of the survey were statistically insignificant. The remaining factors analyzed, i.e., age, BMI, the range of hip motion, the presence of contracture in the joint in a clinical examination, and the radiological advancement of osteoarthritis on the Tonnis scale, do not predict abnormal relationships between the spine and the pelvis in our patients waiting for THA. Therefore, further investigations are needed to evaluate the correlation between preoperative factors and the lumbar-pelvic-iliac complex in patients prior to planned hip arthroplasty.

Abstract
Cerebral palsy in children, which is the result of a nonprogressing damage to the central nervous system, causes motor and posture disorders that change with age. The level of child activity correlates with the hip dislocation risk. It most often affects nonwalking patients and those with tetraparesis or oblique pelvis. The aim of the study was to assess the effectiveness and clinical value of Dega pelvic osteotomy with accompanying directional femoral bone osteotomy after minimum of 20 years from surgery of patients with cerebral palsy. The conducted research was retrospective and concerned the children operated at our Hospital. The assessment was carried out in 346 children with spastic hip during the years 1993-2000. The inclusion criteria were applied: unilateral dislocation of the hip, the observation period of at least 20 years, pelvic osteotomy by Dega method and combined with varus derotation femur osteotomy. The analysis involved fifteen patients. The follow-up period was minimum 20 years (20-27 years). The average migration percentage decreased from 88% down to 25%, and an improved range of mobility was observed in the operated joint after surgery. However, the range of mobility was again significantly reduced during the last control examination after a minimum of 20 years. In all hips, the degenerative joint disease was present. Pelvic transiliac osteotomy, according to Dega, with VDRO, ensures very effective correction of the deficit in femoral head coverage by the acetabulum in the upper, lateral and posterior parts. However, it does not prevent the development of the early degenerative disease of the joint.

Abstract
BACKGROUND Total cementless hip joint arthroplasty is a method commonly used in the treatment of advanced hip osteoarthritis. The aim of this paper is to present the early results of hip joint arthroplasty with the straight Zweymller stem. MATERIALS AND METHODS The study enrolled 117 patients (64 women and 53 men) who underwent a total of 123 hip joint arthroplasties with the straight Zweymller stem. The mean age of the patients at surgery was 60.8 years (range: 26-81 years). The mean follow-up period was 7.7 years (range: 5-12.6 years). RESULTS Pre-operative Merle dAubigne-Postel scores (modified by Charnley) of the study group were poor in all patients. Mean post-operative improvement was 6.3 points. The outcomes were classified as excellent in 42 cases (34.15%), good in 56 cases (45.53%), satisfactory in 14 (11.38%) and poor in 11 cases. Poor results were always associated with implant loosening. Heterotopic ossification was noted in 8 cases (6.5%). According to the Kaplan-Meier estimator, 5-year survival probability was 91.1% for the whole implant and 95.1% for the stem alone. CONCLUSIONS 1. Our follow-up data (from a mean follow-up period of more than 7 years) indicate that the straight Zweymller stem affords excellent clinical and functional results in patients operated on for advanced hip osteoarthritis. 2. In patients correctly qualified for this procedure, with good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal. 3. As only medium-term follow-up data are available, there may be more cases of loosening (mainly of the acetabular cup) over time, indicating a need of regular long-term follow-up.

Abstract
BACKGROUND With the development of hip arthroplasty, there are increasingly more indications for effective use of this surgical method. Endoprostheses are now being more and more commonly used in difficult cases of secondary coxarthrosis and in increasingly younger patients. The aim of this study is to present the early results of hip joint arthroplasty with the Zweymüller conical screw cup. MATERIALS AND METHODS The study enrolled 117 patients (64 women and 53 men) who underwent a total of 123 hip joint arthroplasties with the Zweymüller conical screw cup. The mean age of the patients at surgery was 60.8 years (range: 26-81 years). The mean follow-up period was 7.7 years (range: 5-12.6 years). RESULTS Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) of the study group were poor in all patients. Mean post-operative improvement was 6.3 points. The outcomes were classified as excellent in 42 cases (34.15%), good in 56 cases (45.53%), satisfactory in 14 (11.38%) and poor in 11 cases. Poor results were always associated with implant loosening. Heterotopic ossification was noted in 8 cases (6.5%). According to the Kaplan-Meier estimator, 5-year survival probability was 91.1% for the whole implant and 94.3% for the stem alone. CONCLUSIONS 1. Our follow-up data (from a mean follow-up period of more than 7 years) indicate that the Zwey-müller conical screw cup affords excellent clinical and functional results in patients operated on for advanced hip osteoarthritis. 2. In patients correctly qualified for this procedure, with good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal. 3. As only medium-term follow-up data are available, there may be more cases of loosening over time, indicating a need of regular long-term follow-up.

Abstract
The aim of the study was to analyse the results of uncemented total hip replacement, using the Metha (metaphyseal) stem. A total of 158 patients (70 females and 88 males) were qualified to the study and submitted to total hip arthroplasty (183 procedures altogether), using the Metha stem. The mean age of the patients on the day of surgery was 51.7 years (the range from 17 to 69 years). The mean follow up period was 9.2 years (the range from 5 to 13.5 years). Preoperative assessments gave poor scores, according to the Merle d’Aubigne and Postel classification, modified by Charnley. The average improvement after surgery, according to the used scale, was 6.9 points. A very good outcome was recorded in 154 cases (84.2%), a good outcome was achieved in 20 cases (10.9%) and a poor outcome was confirmed in 9 cases, while no satisfactory case was observed. Poor outcomes were associated with implant loosening. Extraskeletal ossification was noted in 10 cases (5.5%). According to the Kaplan–Meier estimator, the 10-year survival was 93.2% and 97.3% for the whole implant and the stem alone, respectively. 1. Our follow-up period of more than 9 years on the average, indicates that Metha stems produce excellent clinical and functional results in operated young patients with advanced degenerative changes of the hip joint. 2. Assuming a proper qualification for the procedure, the absence of complications and a correct surgical technique, which is slightly more difficult, when compared to standard stem implantation, the risk of aseptic loosening is fairly negligible.

Abstract
BACKGROUND Total cementless hip joint arthroplasty is universally recognized as a method of treatment of ad-vanced hip osteoarthritis. Multifaceted research by a wide group of implant specialists has led to the development of special implants that fulfill their purpose even in the most severe deformities of the hip joint. The aim of the study is to present and analyse the results of hip joint arthroplasty with the Antega anatomical stem. MATERIALS AND METHODS The study enrolled 533 patients (342 women and 191 men) who underwent a total of 595 hip joint arthroplasties with the Antega anatomical stem. The mean age of the patients at surgery was 56.2 years (range: 20-87 years). The mean follow-up period was 7.3 years (range: 5-15.5 years). RESULTS Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) were poor in all patients. Mean post-operative improvement was 6.1 points. The outcomes were classified as excellent in 419 cases (70.4%), good in 102 cases (17.1%), satisfactory in 39 (6.6%) and poor in 34 cases. Poor results were usually associated with loosening of one of the prosthetic components. Heterotopic ossification was noted in 37 cases (6.2%). According to the Kaplan-Meier estimator, 10 years' survival probability was 89.9% for the whole implant and 96.1% for the stem alone. CONCLUSIONS 1. Our follow-up data (from a mean follow-up period of more than 10 years) indicate that the Antega anatomical stem affords excellent clinical and functional results. 2. With good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal. 3. Modification of the Antega stem implantation technique significantly reduces the risk of so-called unexplained thigh pain, which sometimes occurs following hip replacement surgery. 4. As only medium-term follow-up data are available, there may be more cases of loosening (mainly of the acetabular cup) over time, requiring regular long-term follow-up.

BACKGROUND The aim of this study is to present the early results of hip joint arthroplasty with the EXCEPTION anatomical stem (BIOMET). MATERIALS AND METHODS The study enrolled 173 patients (110 women and 63 men) who underwent a total of 190 hip joint arthroplasties with the EXCEPTION anatomical stem. The mean age of the patients at surgery was 58.2 years (range: 28-82 years). The mean follow-up period was 7.3 years (range: 5-10.1 years). RESULTS Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) of the study group were poor in all patients. Mean post-operative improvement was 6.7 points. The outcomes were classified as excellent in 131 cases, good in 39, satisfactory in 13 and poor in 7 cases. Poor results were always associated with implant loosening. Heterotopic ossification was noted in 14 cases (7.4%). According to the Kaplan-Meier estimator, 5 years' survival probability was 96.31% for the whole implant and 99.47% for the stem alone. CONCLUSIONS 1. Our follow-up data (from a mean follow-up period of more than 7 years) indicate that the EXCEPTION anatomical stem affords excellent clinical and functional results. 2. With good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal. 3. Due to the relatively short duration of follow-up, there may be more cases of loosening (mainly of the acetabular cup) over time, requiring regular long-term follow-up.

Abstract
OBJECTIVES The study evaluated the professional activity of patients after a total cementless hip replacement surgery performed at the age of ≤30 years. MATERIAL AND METHODS The study group comprised 87 patients, with 95 total cementless hip replacements. The mean age was 25.7 years. The youngest patient was 17 years old, and the oldest 30 years old. The mean length of observation was 20.1 years, ranging 5-33 years. All patients underwent clinical and radiological evaluations before the surgery, and again in the third, sixth and twelfth months after the surgery. Further follow-up visits were performed every year. The tests were scored according to the Merle d'Aubigné and Postel (MAP) classification, as recommended by the Polish Society of Orthopaedics and Traumatology. Postoperative radiographs were used to assess the position of the endoprosthesis, and the degree of implant healing in the bone tissue. The data was subjected to statistical analysis. RESULTS Of the surveyed group, 67 patients were professionally active before the surgery: 34 were white-collar workers, 29 manual workers, and 4 students or school pupils. The remaining 20 had not worked for many years, and were receiving sickness or disability benefits. An excellent result, according to the Kellgren-Lawrence classification, was noted in 22 cases, a good result in 42 cases, and a satisfactory result in 6 cases. In 25 cases, a poor result was observed. All of the patients professionally active before the surgery returned to work following the procedure. A further analysis found that 15 previously-unemployed patients commenced employment following the procedure. The mean length of the sick leave was 196.2 days, and rehabilitation payments were granted in 5 cases. CONCLUSIONS Total cementless hip replacement is a valuable method of treating osteoarthritis in young patients. All of the patients who worked before the surgery returned to work in the same position and on the same employment conditions. Most of the previously-unemployed patients commenced employment following the procedure.

Abstract
BACKGROUND Rehabilitation following major joint replacement surgery is an extremely important part of complementary treatment after the surgical procedure. To obtain the best final treatment outcome possible, apart from improvements in surgical technique, new methods of rehabilitation are still being sought and implemented to increase its effectiveness, safety and patient comfort. One such technique is vibroacoustic therapy, a method of treatment based on the direct transmission of audible sound vibrations through a sound transmitter to the patient's body. The present study assessed the effectiveness of vibroacoustic therapy in early postoperative rehabilitation of post-TKR and post-THR patients. MATERIAL AND METHODS The study involved 60 post-TKR and post-THR patients divided into two groups depending on the type of surgery. Each group was further divided into an experimental group treated with the VITAFON-2 apparatus and a control group treated with a placebo apparatus; all patients also underwent routine kinesiotherapy that is offered at the hospital. Vibroa-coustic treatment was carried out and evaluated during the first 4 days following surgery. Symptom intensity, range of motion of the operated joints, oedema in the operated limb and haematoma absorption were assessed. RESULTS Postoperative vibroacoustic therapy performed during the first 4 post-operative days reduced pain more significantly than kinesiotherapy alone. It also clinically improved the absorption of post-traumatic haematomas in post-TKR patients insignificantly better than kinesiotherapy. In post-THR patients who had undergone an anterolateral approach procedure, phoning (vibroacoustic stimulation) significantly sped up the rate of recovery of normal internal rotation angles in the operated joints. CONCLUSIONS 1. Vibroacoustic therapy applied topically in post-TKR patients exerts a significant positive effect on reducing pain intensity. 2. Topical vibroacoustic therapy does not significantly reduce the oedema around the operated hip and knee joints or increase their range of motion. 3. Vibroacoustic therapy accelerates the absorption of postoperative subcutaneous haematomas in a clinically visible manner.

Abstract
OBJECTIVES The goal of this work is to analyze the issue of return to professional activity by working-age patients who have been treated surgically with total knee arthroplasty (TKA) due to gonarthrosis. MATERIAL AND METHODS Overall, 88 working-age patients were examined, with a total of 91 TKA procedures performed due to advanced gonarthrosis. The average age of the patients was 54.2 years for women and 58.1 years for men. A modified Knee Society Score scale was used to compile the results of the clinical trial. The Kellgren-Lawrence classification was used to assess preoperative radiographs. Postoperative radiographs evaluated the position of the endoprosthesis of both the femoral and tibial components in the anteriorposterior and lateral upright projections. The obtained results were subjected to statistical analysis. RESULTS In the preoperative assessment, both the clinical and radiological results obtained were unfavorable in all cases. Throughout the observation period of approximately over 3.8 years, a very good result was noted in 65 cases (71.4%), a good result in 20 cases (22%), and a satisfactory result in 6 cases. There were no bad results. The average improvement on the Visual Analogue Scale was 6.5 pts. The radiological assessment did not reveal any radiological symptoms of the aseptic loosening of the endoprosthesis, simultaneously concluding that each time the endoprosthesis components were properly seated. Only 53 (58.3%) of the examined patients were professionally active before the surgery. After completing the treatment, 46 (50.5%) of all patients returned to work, in favor of intellectual workers. The average duration of sick leave was 136.2 days, and rehabilitation allowance was granted in 19 cases. CONCLUSIONS Firstly, in working-age patients, TKA is a valuable method for surgical treatment of advanced gonarthrosis of varying etiology. Secondly, most of the patients who worked before the surgery returned to performing work in the position held and on the same full-time equivalent basis.

Abstract
Bone tissue actively contributes to the regulation of systemic homoeostasis, and particularly the maintenance of calcium-phosphate balance. The parathyroid hormone-vitamin D feedback axis is balanced by the recently discovered bone-FGF23-kidney hormonal axis. An active complex consisting of FGF23, a receptor and Klotho protein blocks phosphate reabsorption in the proximal tubules, increasing urine phosphate levels and decreasing blood phosphate levels. Mutations of the gene mediating FGF23 transcription lead to a number of diseases, examples including autosomal dominant hypophosphataemic rickets. Klotho protein is a cofactor for FGF23 displaying cardio-, vaso- and nephroprotective activity. It increases calcium reabsorption in the kidneys and inhibits phosphate reabsorption. It also exerts antioxidative and anti-insulin effects and inhibits tissue calcification and apoptosis. As an inhibitor of bone resorption, osteoprotegerin becomes an important contributor to bone remodelling, while RANK/RANKL signalling inhibition is used in the treatment of postmenopausal osteoporosis. Osteocalcin plays an important role in energy metabolism in the human body. Sclerostin exerts a strong catabolic effect on bone tissue. Newly identified contributors to the regulation of calcium and phosphate homoeostasis suggest that bone tissue plays a complex role in the systemic metabolism.

Abstract
BACKGROUND Peripheral nerve damage is a rare complication of hip replacement surgery that severely impairs the therapeutic outcome. The aim of the present study was to determine the time needed for nerve recovery and re-storation of activity following iatrogenic damage during a primary or revision hip arthroplasty from an anterolateral approach and its relationship with the severity of damage. MATERIALS AND METHODS A prospectively collected database of 1107 patients treated with primary arthroplasty and 303 patients following revision arthroplasty (mean age 63 years, range 53 to 72 years) was analysed. This included 15 cases of palsy of the peroneal branch of the sciatic nerve and 7 of the femoral nerve. The mean follow-up was 3.6 years (minimum two years). RESULTS The following risk factors were identified: dysplastic osteoarthritis, limb elongation, revision arthroplasty, female sex and post-traumatic osteoarthritis. All five patients demonstrating light palsy (Lovett score 3-5), and 9 out of the 17 with severe palsy (Lovett score 0-2) achieved full recovery. Of all patients, 63.6% regained nerve function after 4 weeks to 24 months (mean 17 months), with nine demonstrating complete recovery and five partial. Also, 66.6% patients regained femoral nerve function and 61.5%, sciatic nerve function. CONCLUSION 1. The femoral nerve and the peroneal branch of the sciatic nerve demonstrate a similar pattern of functional recovery following damage. 2. All patients recovered from light palsy, and almost 2/3 of cases of severe palsy demonstrated partial or complete recovery. 3. Female sex is a significant risk factor.

Abstract
BACKGROUND The aim of this study is to analyse the outcomes of total cementless hip joint arthroplasty in the treatment of advanced hip osteoarthritis following Perthes' disease in childhood. MATERIAL AND METHODS The study enrolled 56 patients (15 women and 41 men) who underwent a total of 61 hip joint arthroplasties for coxarthrosis following Perthes' disease. The mean age of the patients at surgery was 46.7 years (range 21-67 years). The mean follow-up period was 13.7 years. RESULTS Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) of the study group were poor in all patients. Mean post-operative improvement was 6.7 points. The outcomes were classified as excellent in 25 cases, good in 16, satisfactory in 16 and poor in 9 cases. Poor results were always related to loosening of the acetabular cup. Heterotopic ossification was noted in 7 cases. According to the Kaplan-Meier estimator, 10 years' survival probability was 85.24% for the whole implant and 100% for the stem. CONCLUSIONS 1. Total cementless hip joint arthroplasty is an effective method in the treatment of advanced hip osteoarthritis following Perthes' disease in childhood. 2. With good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal. 3. Due to the patients' young age, there may be more cases of loosening over time, requiring regular long-term follow-up.

The Influence of Hippotherapy on the Body Posture in a Sitting Position among Children with Cerebral Palsy. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E6846. [PMID: 32961681 PMCID: PMC7558765 DOI: 10.3390/ijerph17186846] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 09/14/2020] [Accepted: 09/18/2020] [Indexed: 11/16/2022]
Abstract
The purpose of this study was to assess the influence of hippotherapy (therapy with horses) on posture and body function among children with cerebral palsy. A case-control study included forty-five children aged 6-12 years, classified as Gross Motor Function Classification System (GMFCS) level I or II, with spastic diplegia or hemiplegia. The participants were randomly divided into three groups: study I (n = 15), study II (n = 15) and control (n = 15). The children from the study groups attended 30min hippotherapy sessions for 12 consecutive weeks, twice (study group I) or once (study group II) a week. The Sitting Assessment Scale (SAS) was used. A comparison of SAS showed an improvement in almost all the assessed categories among the children who participated in hippotherapy. In study group I, statistically significant differences were noted in the assessment of head position control, arm function (in both cases, p = 0.012) and trunk control (p = 0.005) and in study group II in the assessment of trunk control (p = 0.028). Hippotherapy has a positive influence on the body posture and function of individual body parts in a sitting position among children with cerebral palsy.

Abstract
BACKGROUND The aim of the paper is to describe the outcomes of hip arthroplasty with the anatomical AURA II stem (BIOMET). MATERIAL AND METHODS The study enrolled 189 patients (105 women and 84 men) who underwent a total of 213 hip arthroplasty procedures with the anatomical AURA II stem. Mean age of the patients at surgery was 61.7 years (range: 21 to 76 years) and mean follow-up period was 131.9 months (11 years). RESULTS Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) of the study group were poor in all patients. Mean post-operative improvement in the scores was 6.8 points. Excellent results were obtained in 123 cases, good in 22, fair in 24 and poor in 44 cases. The poor results were always associated with acetabular cup loosening. A total of 13 (6.1%), patients developed heterotopic ossification. According to the Kaplan-Meier estimator, 10 years' survival probability was 76.19% for the whole endoprosthesis and 100% for the stem alone. CONCLUSIONS 1. Our follow-up data from a mean of 11 years show that the use of the anatomical AURA II stem results in a considerable reduction in hip pain and produces good and lasting clinical outcomes. 2. With good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal.

Abstract
BACKGROUND Posture disorders not treated in early childhood may lead to serious diseases and dysfunctions later. The aim of the study was to assess the incidence of lower limb defects in pre-school children. MATERIAL AND METHODS The study covered 513 children (252 girls and 261 boys) aged 4-6, in chosen kinder-gartens of the Łódź agglomeration . The child's body posture was assessed using a visual method based on the Kasperczyk scoring scale in own modification. RESULTS Foot defects occurred in the examined group with a frequency of 85.58% (439/513): in 4-year-olds: 82.59%, in 5- and 6-year-olds: 87.5%. Foot defects were more common in girls in the entire study group (86.9 vs. 84.29%), in 4-year-olds (87.88 vs. 77.45%) and 6-year-olds (88.89 vs. 86.25%), and in boys in the 5-year-olds group (91.14 vs. 83.95%). Defects of the knee joints, including varus and valgus knee, occurred in the study group with a frequency of 52.83% (271/513): in 4-year-olds: 56.72%, in 5-year-olds: 45.63% and in 6-year-olds: 55.26%. Defects were more frequent in girls in the entire study group (54.37 vs. 51.34) and in 4-year-olds (58.59 vs. 54.90%), and in boys in the 5-year-old group (50.63 vs. 40.74%). In the 6-year-olds group, the defects were statistically significantly more common in girls than boys (63.89 vs. 47.5%, p = 0.0442). CONCLUSION A high percentage of lower limb defects rate at more than half of the examined pre-school children population is disturbing and requires effective systemic action.

Abstract
It is widely acknowledged that anterior cruciate ligament (ACL) injury is the cause of anterolateral insta-bility, but in some cases not only the ACL ruptures, but also anterolateral structures (ALS), including the antero-lateral ligament. Their insufficiency may be the cause of residual instability after ACL reconstruction, which significantly increases the risk of graft rupture. In the past, anterolateral instability caused by ACL injury was treat-ed with extra-articular reconstructions, including lateral extra-articular tenodesis. Nowadays those techni-ques are used simultaneously in cases of complex anterolateral and rotational instability. This article briefly describes historical methods of lateral tenodesis and presents step-by-step two techniques used in our depart-ments involving two alternative graft femoral fixation methods.

Abstract
BACKGROUND The multifactor aetiology of adolescent idiopathic scoliosis is commonly acknowledged. Both multivariate analyses of large study groups and the search for causes of adolescent idiopathic scoliosis and its progression in individual patients indicate that the aetiopathogenesis of this disorder is remarkably complex. The discovery of novel bone turnover markers, such as Klotho protein and FGF-23, means that their role in this condition also has to be considered. The aim of this paper is to evaluate the FGF-23 and Klotho protein concentration profiles as new contributors to the regulation of calcium and phosphate metabolism in children with adolescent idiopathic scoliosis and compare them with the values seen in healthy children. MATERIAL AND METHODS The study assessed a total of 70 children, including 35 children treated at the postural defects clinic of the Health Care Facility in Oleśno following a diagnosis of adolescent idiopathic scoliosis and 35 healthy children who constituted a control group. The levels of classic bone turnover markers, such as calcium and phosphorus concentration, alkaline phosphatase, 25-OH-D, and parathyroid hormone (PTH) activity, and of newly discovered contributors to calcium and phosphate metabolism regulation, namely Klotho protein and FGF-23, were determined in both groups. RESULTS There were statistically significant differences in the levels of basic parameters of calcium and phosphate metabolism between children with scoliosis and the control group, with scoliotic patients showing elevated calcium and 25-OH-D levels and reduced parathyroid hormone levels. Klotho protein levels in children with scoliosis were significantly lower than in the control group. Moreover, the scoliotic patients showed a marked trend towards higher FGF-23 levels as compared to the control group. CONCLUSIONS 1. Adolescent idiopathic scoliosis is characterised by multi-level abnormalities of calcium and phosphate metabolism. 2. The increased FGF-23 levels and reduced Klotho protein concentrations found in serum samples collected from children with ado-lescent idiopathic scoliosis may suggest that these hormones play a role in the aetiopathogenesis of the disorder.

Abstract
BACKGROUND AND OBJECTIVES We have investigated how low intensity laser irradiation emitted by a multiwave-locked system (MLS M1) affects the viability and proliferation of human bone marrow mesenchymal stem cells (MSCs) depending on the parameters of the irradiation. STUDY DESIGN/MATERIALS AND METHODS Cells isolated surgically from the femoral bone during surgery were identified by flow cytometry and cell differentiation assays. For irradiation, two wavelengths (808 and 905 nm) with the following parameters were used: power density 195, 230, and 318 mW/cm 2 , doses of energy 3, 10, and 20 J (energy density 0.93-6.27 J/cm 2 ), and in continuous (CW) or pulsed emission (PE) (frequencies 1,000 and 2,000 Hz). RESULTS There were statistically significant increases of cell viability and proliferation after irradiation at 3 J (CW; 1,000 Hz), 10 J (1,000 Hz), and 20 J (2,000 Hz). CONCLUSIONS Irradiation with the MLS M1 system can be used in vitro to modulate MSCs in preparation for therapeutic applications. This will assist in designing further studies to optimize the radiation parameters and elucidate the molecular mechanisms of action of the radiation. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Abstract
Pachydermoperiostosis is a rare condition representing a primary form of hypertrophic osteoarthropathy. It presents in different stages. Patients often overlook early symptoms, because they are benign. The most common manifestations are clubbing of the fingers and toes, skin thickening with characteristic folds on the face and head and widening of joints accompanied by radiological changes. Surgical treatment is not often needed, and, consequently, there are no strict guidelines on surgical management, which is mainly based on case report ana-lysis. This paper presents a case of surgical management of pachydermoperiostosis.

Possible Approaches to Endoscopic Treatment of Popliteal Cysts: From the Basics to Troublesome Cases. Arthrosc Tech 2019; 8:e375-e382.

Abstract
Popliteal cysts can be an oppressive symptom in patients with concomitant intra-articular knee pathologies. Because isolated treatment of intra-articular lesions is usually not sufficient to resolve the problems associated with a large symptomatic popliteal cyst, a popliteal cyst should be concurrently addressed with other knee pathologies to maximize patient outcomes. Conservative treatment and open surgical excision are associated with high rates of recurrence, so arthroscopic techniques are the preferred treatment options for recalcitrant cases. Arthroscopic communication-enlargement surgery with cyst wall removal seems to be the most effective. We present a simple and effective basic technique for arthroscopic popliteal cyst treatment and some approaches that allow management of the more demanding cases.

Abstract
OBJECTIVES The primary endpoints of the study were to assess the effectiveness of hip joint arthroscopy in the treatment of femoroacetabular impingement (FAI) in patients with joint gap stenosis and to determine if and how quickly patients were able to return to work and physical activity. MATERIAL AND METHODS The prospective study of patients undergoing hip joint arthroscopy due to pain in FAI has been conducted. They were divided into 2 groups depending on the degree of the radiological examination. The criterion was the width of the joint gap. The study group involved 47 patients with hip joint gap of 2-3 mm, identified by means of the standardized X-ray examination. The control group consisted of 45 patients with hip joint gap > 3 mm. The post-operative follow-up period of the patients lasted at least 2 years. In addition, the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) questionnaire together with Harris Hip Score (HHS) were applied. The patients were also evaluated for the post-operative time period enabling return to work. RESULTS All the patients after hip joint arthroscopy returned to normal physical activity within 12 weeks after operation, enabling their return to work. However, it should be noted that during the post-operative follow-up, pain sensations either recurred or did not regress in 37 patients in the study group and 12 patients in the control group after treatment. The nearly equal results of the WOMAC questionnaire and HHS before operation significantly vary between both groups in the last follow up. In the study group they did not change expressively. CONCLUSIONS Despite the little invasiveness, hip joint arthroscopy in patients with joint gap stenosis brings about the far from satisfactory results. This procedure is not worth considering. Despite unsatisfactory pain relief, patients decided to returned to work, due to their occupational position and for fear of losing the job due to long absenteeism.

Abstract
BACKGROUND Trabecular metal implants with a porous architecture that allows for the incorporation of bone into the implant during healing are gaining popularity in alloplastic revision procedures. The bi-products of drilling titanium alloy (Ti) and tantalum (Ta) implants have not been previously assessed. METHODS Four holes were drilled in each of 2 spatially porous trabecular implants, one Ta and the other Ti alloy (Ti-6Al-7Nb), for this pilot in vitro study. The particles were flushed out with a continuous flow of saline. The particles' weight and the volume were then measured using a Radwag XA 110/2X (USA) laboratory balance. The total volume of the obtained metal fines was measured by titration using a 10 mm3 measurement system. RESULTS A cobalt carbide bit was used since the holes could not be made with a standard bone drill. Each Ti and Ta implant lost 1.26 g and 2.48 g of mass, respectively. The volume of free particles recovered after each stage was 280 mm3 and 149 mm3, respectively. Approximately 0.6% of the total implant mass was not recovered after drilling (roughly 2% of the mass of the particles created by drilling), despite the use of 5 µm filters. CONCLUSIONS It is technically difficult to drill holes in Ti and Ta implants using standard surgical tools. The drilling process creates a considerable amount of metal particles, which cannot be recovered despite intensive flushing. This may have an adverse influence on the bio-functionality (survival) of the endoprosthesis and present deleterious systemic consequences.

Abstract
The aim of this paper is to present the femoral stem fracture as a rare complication of total hip arthroplasty and describe further management in such cases. We present 5 cases of stem fracture in the Mittelmeier prosthe-sis which occurred from 8 to 29 years after the primary procedure. In three cases, the primary hip arthroplasty was performed due to dysplastic coxarthrosis. The remaining two patients had idiopathic and post-traumatic coxarthrosis. The four female patients underwent revision hip arthroplasty with stem replacement. One patient refused surgical treatment and has been followed up at the outpatient clinic. Annual clinical and radiological examination is an approved method for detecting late complications Hip arthroplasty should be performed at specialised centres where relevant prostheses and instruments are used. A transfemoral approach and the use of revision stems anchored in the femoral shaft is a method of choice for revision procedures performed due to stem fractures.

Abstract
BACKGROUND Both ultrasound and radial shockwave therapies are used to treat tennis elbow syndrome. The aim of this study was to compare the therapeutic efficacy of both therapies by assessing the reduction in pain intensity and frequency, restoration of mobility, and reduction in the need for pain medication. MATERIAL AND METHODS The study enrolled 60 people, who were randomly divided into two groups of 30 patients: those treated by radial shockwave therapy and those treated by ultrasound therapy. Radial shockwave therapy consisted of 3 sessions at weekly intervals. Ultrasound therapy consisted of 10 treatments performed daily. The clinical status of the patients before treatment, just after treatment, and after 8 weeks was assessed with the Leitinen questionnaire and a visual analogue scale (VAS). RESULTS Pain reduction, as assessed by VAS scores, was observed in both groups, who were not different at baseline (p=0.807). While both therapies were effective (p<0.005), mean pain intensity assessed by VAS scores in patients treated by radial shockwave therapy was significantly lower compared to those treated by ultrasound therapy; this relationship was present just after treatment completion (p=0.001) and at 8 weeks after treatment completion (p=0.002). CONCLUSIONS 1. Both radial shockwave and ultrasound therapies cause a reduction in the intensity and frequency of pain that persists for at least 8 weeks, reducing the need for pain medication and improving the function of the treated upper limb. 2. Ultrasound therapy is less effective than radial shockwave therapy.

Abstract
BACKGROUND Total hip arthroplasty is currently commonly used in surgical treatment of advanced hip osteoarthritis of various aetiologies. Studies show that the number of these procedures has been growing every year, which is associated with global population ageing. The aim of the study was to assess return to work in patients after surgical treatment by arthroplasty due to hip osteoarthritis. MATERIAL AND METHODS The study assessed 114 patients of productive age who underwent surgery due to advanced hip osteoarthritis. The mean age was 49.9 years in women and 52.2 years in men. All patients included in this retrospective study underwent clinical and radiographic assessment prior to arthroplasty and at the last out-patient follow-up visit. The patients' occupational status and the time of return to work after surgery were also assessed. The results of this clinical study were analysed according to the Merle d'Aubigne-Postel classification (modified by Charnley). Preoperative radiographs were assessed according to the Kellgren-Lawrence classification. The radiographs served to assess the position of the endoprosthesis, including both the acetabular component and the stem. The results were statistically analysed. RESULTS Pre-operative assessment classified all cases as poor both clinically and radiographically. The post-operative outcomes were excellent in 71 cases (61.7%), good in 37 cases (32.2%) and fair in 7 cases. No case was classified as poor. The mean improvement was 6.6 points and reached the level of statistical significance. Radiographic evaluation did not reveal evidence of aseptic implant loosening and confirmed a normal seat of endoprosthetic components within the Lewinnek safe zone in each case. Only 75 (65.8%) of the study participants worked before the procedure. After the treatment was completed, 67 (58.8%) study patients took up employment. The mean duration of sick leave was 138.6 days and 21 patients were receiving rehabilitation benefits. CONCLUSIONS 1. Total hip arthroplasty is a valuable method of surgical treatment of advanced coxarthrosis of various aetiologies in patients of productive age. 2. Most patients who worked before the surgery return to work in the same position and work time. 3. Only dysplastic coxarthro-ses have an unfavourable prognosis with respect to starting or resuming work after surgery.

Abstract
With aging of the population, osteoporotic fractures are becoming an increasing medical problem world-wide. It has been estimated that 2,700,000 patients experienced a low energy fracture in the Polish population in 2010. On the basis of contemporary world standards and publications in the field of orthopaedics and trau-matic surgery, a summary of the principles of management of osteoporotic fractures is presented. Both general problems of fracture treatment in elderly patients as well as difficulties in surgical and conservative treatment resulting from osteoporotic bone abnormalities are discussed. Special attention is paid to preoperative and postoperative procedures in patients with proximal femur fractures. Also presented is a contemporary strategy for the treatment of fractures of the distal forearm, proximal humerus and vertebrae. General principles of diagnosis and treatment of osteoporosis are discussed.

Preoperative Ultrasonographic Assessment of the Anterior Pelvic Plane for Personalized Total Hip Replacement.

Abstract
OBJECTIVES Correct positioning of the acetabular component is a key factor in minimizing the risk of dislocation after total hip replacement (THR) surgery. A "safe" orientation of the cup is usually defined by 2 angles measured between its geometric axis and the anterior pelvic plane. However, in the current state-of-the-art approach to THR surgery, the intraoperative orientation of the anterior pelvic plane cannot be measured. Even less is known about the functional orientation of the pelvis, which determines the postoperative orientation of the cup during the patient's everyday activities. The aim of this article is to present an original approach to personalized THR surgery, in which the necessary measurements are done preoperatively without interfering with the surgical work flow, and the individual orientation of the cup is obtained without navigation using standard tools that are available in the operating room. METHODS To quantify the effect of the anatomic conditions on the final orientation of the cup, we measured the orientation of the anterior pelvic plane in 43 patients scheduled for THR using a newly developed noninvasive method based on ultrasonography and mobile devices. RESULTS Our results confirm a large variability of the pelvic orientation in both supine and standing positions. We further show how this variability affects the final position of the cup and discuss its consequences for the patient. Finally, we explore a few practical solutions for individualized cup placement, including our own approach, which is based on tilting of the operating table. CONCLUSIONS In this work, we show that the common guidelines used today for cup implantation can only be effectively applied to a small portion of the population. In most cases, it is crucial that the orientation of the cup is readjusted for the particular anatomy of the individual patient.

An evaluation of the potential consequences of drilling titanium and tantalum implants during surgery - a pilot study. BMC Musculoskelet Disord 2017; 18:426. [PMID: 29100511 PMCID: PMC5670512 DOI: 10.1186/s12891-017-1784-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2017] [Accepted: 10/23/2017] [Indexed: 11/12/2022] Open
Abstract
Background The aim of the study was to evaluate the potential consequences of drilling titanium alloy (Ti) and tantalum (Ta) implants. Methods During an in vitro study, four holes were made in each of two spatially porous trabecular implants: one Ta and the other Ti alloy (Ti-6Al-7Nb). The weight and the volume of particles produced during the drilling were then measured using a Radwag XA 110/2X (USA) laboratory balance. Results The loss of mass of the Ti and Ta implants was respectively 1.26 g and 2.48 g, and the volume of free particles was respectively 280 mm3 and 149 mm3. The particles were recovered after each stage. Despite the use of 5 μm filters, around 0.6% of the total implant mass from both implants was not recovered after drilling (roughly 2% of the mass of the particles created). Conclusion It is technically difficult to make holes in Ti and Ta implants using standard surgical tools, and the process creates a significant amount of metal particles which cannot be removed, despite intensive flushing. This may have a potentially adverse influence on the survival of the implant and result in negative systemic consequences.

Abstract
BACKGROUND The aim of this study was to compare the results of TKA performed with the use of a navigation system vs. conventional knee arthroplasty and to evaluate the effectiveness of navigation system support in TKA. MATERIAL AND METHODS We evaluated patients undergoing TKA for osteoarthritis in the years 2011-2013. Columbus prostheses were implanted in 84 knees. Group 1 included patients in whom TKA was performed with the use of the OrthoPilot Navigation System, and Group 2 was a control group of patientsundergoing conventional TKA. Group 1 ultimately comprised 30 patientsat a mean age of 71.8 years, while Group 2 consisted of 30 patients at a mean age of 73.5 years. Radiographic parameters were evaluated according to the mechanical axis of the leg. Clinical evaluation relied on the VAS and KSSscores. RESULTS Mean operation time was 94 minutes in Group 1.It was shorter in Group 2, with a mean of 75 minutes. Postoperative VAS scores did not differ betweenthe groups. Significant improvement was noted between pre- and postoperative in KSS scores in both groups. The control group showed more valgus mechanical axis deviation than varus deviation. CONCLUSIONS In experienced hands, navigated surgery time may be similar to that of conventional TKA and give superior results, both clinical and radiographic.

Abstract
Objective This prospective randomized study was performed to compare the outcomes of two operative methods of anterior cruciate ligament (ACL) reconstruction based on either bone–patellar tendon–bone (BTB) grafts or hamstring tendon (HT) grafts. Methods Among 100 patients, 96 completed the full follow-up period and were included in the final analysis (48 in the BTB group and 48 in the HT group). The patients were evaluated preoperatively and 1, 3, 6, and 12 months after ACL reconstruction. The Kujala score, Tegner score, and Knee injury and Osteoarthritis Outcome Score (KOOS) were among the parameters used to evaluate the patients. Results Both groups were comparable in terms of sex, age, and body mass index. None of the analyzed scores were significantly different between the BTB and HT groups at either the initial or last visit. Both groups demonstrated improvement at the 12-year follow-up according to the Kujala score and most categories of the KOOS. The Tegner activity level score showed significant improvement in the HT but not BTB group. Conclusion Patients undergoing ACL reconstruction with BTB and HT grafts show comparable improvement in functional results after 1 year of rehabilitation.

Application of Navigated Ultrasound for Assessment of the Anterior Pelvic Plane in Patients With Degenerative Hip Diseases. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2017; 36:1373-1380. [PMID: 28390166 DOI: 10.7863/ultra.16.07016] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2016] [Accepted: 09/23/2016] [Indexed: 06/07/2023]
Abstract
OBJECTIVES Correct positioning of the acetabular cup is the key for successful total-hip replacement. In common clinical practice, the target alignment of the cup is defined with respect to the anterior pelvic plane. In patients with substantial anterior pelvic plane inclination, this condition may lead to inappropriate distribution of the load on the cup, as most of the forces exerted within the hip joint act along the vertical axis. With the known pelvic inclination, it is possible to readjust the position of the cup with respect to the individual posture of the patient. In this work, we present the first clinical evaluation of a new approach to measurement of the pelvic tilt angle using navigated ultrasound. METHODS In our method, the ultrasound probe is tracked with an optical localizer implemented on a handheld mobile device. The method was tested by taking preoperative measurements from 20 patients with osteoarthritis in standing, sitting, and supine positions. RESULTS The mean values of the measured angles were consistent with the corresponding results reported by other authors. CONCLUSIONS Considering the noninvasiveness of the method and affordability of the hardware used in our system, it can be used in preoperative and postoperative measurements of pelvic orientation for supporting surgery planning and evaluation of treatment outcomes.

Abstract
PURPOSE The aim of this study was to compare two methods of two-stage surgery for PJI (periprosthetic joint infection) after THA (total hip arthroplasty): one with and one without the use of an antibiotic-loaded cement spacer. METHODS This retrospective study was performed on 99 consecutive patients (99 hips) with a minimum follow-up of 24 months. Patients were divided into two groups: (1) in whom the operation was performed using a spacer, and (2) for whom a spacer was not used. RESULTS For the whole cohort, the results improved between pre-operative and final follow-up. Recurrence of infection was found in nine out of 98 patients (9.2%) and was not significantly different between the two groups. Patients treated with a spacer had better functional improvement in the interim period, but the VAS score was better in the non-spacer group. The improvement in final function was better in the spacer group with regard to HHS, but not according to WOMAC score or VAS at final follow-up. CONCLUSION The resection arthroplasty should be awarded particular consideration in cases of poor soft tissue quality, bone stock deficiency, when complications related to spacer use are expected or chances of new hip endoprosthesis implantation are low.

Abstract
BACKGROUND The opinion about best methods of femoroacetabular impingement (FAI) treatment are not consistent. Operative treatment of this condition may be arthroscopic, but open procedures with osteotomy of the greater trochanter and hip dislocation has been used. The present study evaluates the benefits of the mini-open direct anterior approach (DAA) in treating patients with FAI, with is a procedure available for most orthopedic surgeons. MATERIALS AND METHODS 39 patients treated for FAI (25 men and 14 women) at an average age of 29.3 years (range 18-46 years) were reviewed in this retrospective study. The mean followup was 45 months, (range 24-55 months). The hip impingement test was positive in all patients. The diagnosis of FAI was confirmed on anteroposterior and lateral hip view radiographs. All patients were operated with mini-open DAA. The outcomes were assessed with the Harris Hip Score, Short-Form 36 Health Survey and VAS score. Preoperative osteoarthritis was assessed according to Tönnis score. RESULTS At the final followup, improvement was noted compared to preoperative status in Harris Hip Score (P < 0.00001), visual analog scale score (P < 0.001), and Short-Form-36 score (P < 0.001). Nineteen patients returned to their previous sports activities. No major complications occurred. One patient developed heterotopic ossification and three patients developed temporary postoperative meralgia paresthetica. Five patients from the treatment group required total hip arthroplasty for severe osteoarthritis. CONCLUSIONS Mini-open DAA is a safe and effective procedure for the treatment of FAI that gives good relief of symptoms and allows a successful return to preoperative activity levels. Further research with a longer followup period is needed to evaluate the influence of surgery on natural history of FAI.

Abstract
BACKGROUND The original knee megaprostheses with fixed or rotating hinge articulation were custom made and only used for reconstruction of the knee following distal femoral or proximal tibial tumor resections. The aim of the study was to analyze the short- and mid-term results of revision total knee arthroplasty with Global Modular Replacement System (GMRS) used in difficult situations not amenable to reconstruction with standard total knee replacement implants. MATERIALS AND METHODS Nine patients (9 knees) were treated with this comprehensive modular implant system, with a mean age of 73.7 years (range 56-83 years) and a mean followup of 5 years (range 3-8 years). Two patients were treated for distal femoral nonunion, five for distal femur periprosthetic fracture and two for periprosthetic joint infection. RESULTS The mean Knee Society Score: Knee and functional scores were 77.9 and 40 points, respectively. All demonstrated full extension and flexion was at least 90°. Recurrence of infection was present in one patient. No signs of loosening, dislocation, or implant failure were observed. CONCLUSIONS Based on our small series of patients that represent severe cases, GMRS provides relatively good mid-term functional results, pain relief, and good implant survivorship with a low complication rate. This salvage procedure allows elderly, infirm patients to regain early ambulatory ability.

Abstract
BACKGROUND Autologous Conditioned Plasma (ACP) has a wide range of potential uses in modern orthopaedics. The aim of this study was to examine the characteristics of proprietary ACP and compare them with those of ACP produced using a commercially available kit. MATERIAL AND METHODS In the hospital laboratory, 20 samples of ACP taken from patients and prepared according to the commercially available kit protocol with a double syringe system were compared with 40 ACP preparations made using disposable sterile equipment available in the hospital. RESULTS The mean platelet concentration in the ACP samples prepared according to the Arthrex protocol was 2.02 (range 1.16 to 2.64) times greater than in peripheral blood, while the concentration in the proprietary preparation was 1.61 (range 0.82 to 2.52) times higher. However, the mean platelet density in the proprietary preparation (n = 24) was 1.98 (range 1.48 to 2.52) times that of peripheral blood within 20 minutes of collection, and 1.41 (range 0.84 - 1.87) times after 20 minutes (n = 16). Therefore, the proprietary method of producing ACP is comparable to that of the commercial kit with regard to platelet density (p>0.05). CONCLUSION Using disposable hospital equipment and with a relatively short time between ACP preparation and testing, it is possible to obtain a suitable proprietary platelet-rich preparation comparable to one produced using a commercial system.

Abstract
BACKGROUND Surgical treatment of idiopathic degenerative disease of the knee joint with total arthroplasty is aimed at reducing concomitant pain and improving the limited range of motion. This paper aims to assess the influence of pain intensity and range of motion on the presence of knee joint stiffness after primary total arthroplasty. MATERIAL AND METHODS 59 male and female patients were divided into two groups based on the presence (G1) or absence (G2) of stiffness in the operated knee joint at 3 months post-operatively. Patients completed a questionnaire evaluating the following: sex, age, BMI, pain intensity in a VAS scale and the range of motion of the operated knee joint. The functional status was assessed with the WOMAC score. RESULTS Mean age was 68.20 ± 7.02 years in Group 1 (23 women, 7 men) and 67.66 ± 7.47 years in Group 2 (20 women, 9 men). In the first examination, mean active flexion range of motion (ROM) of the operated knee joint was 98.00° ± 10.39° in Group 1 and 92.07° ± 12.14° in Group 2; in the second examination, it was 88.83° ± 4.68° in Group 1 and 90.69° ± 6.23° in Group 2 (p<0.05). The total WOMAC score was 51.13 ± 13.48 in Group 1 and 51.28 ± 15.32 in Group 2 in the first examination and 18.50 ± 9.38 in Group 1 and 13.17 ± 9.02 in Group 2 (p<0.05) in the second examination. CONCLUSIONS 1. Pain and range of motion in the operated joint may need to be taken into consideration as factors in the development of stiffness in the early post-operative period after primary total knee arthroplasty. 2. There is a need for further research on the problem of knee joint stiffness in the early post-operative period.

Abstract
BACKGROUND The aim of our study was an evaluation of long-term clinical and radiological results of arthroplasty with BiCONTACT stem. MATERIAL AND METHODS We qualified 115 patients (125 hips) to the retrospective analysis with a minimum 10-year follow-up period. The mean age of patients on the day of surgery varied was 50.7 years. The follow-up period lasted from 126 to 199 months (mean 14 years). RESULTS Harris hip score increased from 47.1 before operations to 85.3 at the last follow-up. Excellent results were recorded in 81 (64.8%) cases, good results in 23 (18.4%) and satisfactory results in 10 (8%) cases, while failure was noted in 11 cases. In 2 cases, aseptic stem loosening was identified, in 8 cup and in 2 cases both: cup and stem loosening. The BiCONTACT stem survival, assessed with the Kaplan-Meier estimator was 97.6%, while that of the both: cup and stem amounted to 91.2%, having taken into account acetabulum or stem loosening as end-point, regardless of cause. CONCLUSIONS 1. In an average 14-year observations, application of a BiCONTACT stem gives good clinical results. 2. With no incidental complications and proper operative technique, the risk of aseptic loosening is really scarce.

Abstract
The aim of the study was to determine the degree of posterior cruciate ligament (PCL) degeneration and the reduction in the number of its mechanoreceptors, in patients with advanced degenerative joint disease. PCLs taken from study group of 50 patients in the mean age of 70.7 (53-84) years with a diagnosis of advanced idiopathic osteoarthritis undergoing condylar total knee arthroplasty were compared to those taken form the control group of 10 knee joints of cadavers. Groups were matched with regard to sex and age. Histological examination of PCLs of the study group showed changes of an inflammatory process and no significant signs of osteoarthritis in the control group. A close correlation was found between the severity of degenerative changes on the X-ray images according to the Ahlbäck scale, and the increased mucoid degeneration (p < 0.0001), the severity of the degeneration of the collagen structure (p < 0.0001) and the presence of proprioceptors of PCLs (p < 0.0001). Conserving the PCL by the use of type cruciate retaining knee arthroplasty does not guarantee the preservation of correct proprioceptive sensation.

Abstract
UNLABELLED Ultrasound examinations are recognised as being safe. The greatest epidemiological threat during the performance of examination is the transfer of pathogenic and opportunistic microorganisms between patients and from personnel to patients. Colonization of the skin with opportunistic bacteria of immunocompromised and high risk patients may lead to infection following an ultrasound scan. AIM To identify and evaluate the strains of bacteria occurring on ultrasound equipment subjected to unexpected control performed by a local infectious diseases control team. We assumed that transducers, gel holders and gel bottles can be contaminated with normal human skin microflora. The remaining tested parts of the ultrasound equipment could possibly be contaminated with normal human skin microflora and other pathogens. MATERIAL AND METHODS The swabs were taken from ultrasound scanners located in various hospital settings, from out-patient based radiology scanning rooms to operating theatre, and cultured. RESULTS Among all isolated 23% strains were classified as environmental microflora; 8% as strains related to patient's skin contamination; and 13 % strains constituted pathogenic Gram-negative rods.. The remaining strains were classified as opportunistic flora 38%. High prevalence of opportunistic bacteria cultured in our study lead to the modification of the ultrasound cleaning procedures in both institutions and recommendation of the use of antibacterial wipes to clean all parts of ultrasound equipment in contact with patients' skin and examiners. CONCLUSIONS Contamination not only affects parts of diagnostic equipment placed in direct contact with the patient, but also, those surfaces that only medical personnel have had contact with.

Abstract
BACKGROUND The aim of this paper is to present the results of hip joint arthroplasty with the use of the Taperloc stem. MATERIAL AND METHODS The study group consisted of 117 patients (75 women and 42 men) who underwent 121 hip joint arthroplasties with Taperloc stems. Mean age of the patients at surgery was 53.8 years (range: 2475 years). Mean follow-up period was 159.5 months. RESULTS Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) of the study group were poor in all patients. Mean post-operative improvement was 6.6 points. Excellent results were obtained in 86 cases, good in 19, fair in 9 and poor in 7 cases. Poor results were always associated with implant component loosening: 5 cases of acetabular cup loosening, 1 case of a loosened stem and 1 septic loosening of the entire endoprosthesis. In six cases (4.9%), patients developed heterotopic ossification. According to the Kaplan-Meier estimator, 10 years' survival probability was 94.21% for the whole endoprosthesis and 98.34% for the stem alone. CONCLUSIONS 1. Our follow-up data covering a mean period of over 13 years showed that the use of the Ta-perloc stem substantially reduces hip pain and results in a good lasting clinical outcome. 2. With good surgical technique and in the absence of complications, the risk of aseptic loosening is minimal.

Abstract
Congenital bladder exstrophy is a severe congenital malformation identified in one out of 30,000-50,000 live newborns and seen more often in girls. Some patients develop osteoarthritis of the hip joints which requires total hip arthroplasty. Reports of such cases are very rare in the world literature, which prompted us to present two cases treated at our Department and analyse their early outcomes. Our experience so far has been rather modest but the results encourage considering total hip arthroplasty in the treatment of hip osteoarthritis in future patients with pubic symphysis separation in the course of congenital bladder exstrophy.

Abstract
PURPOSE To evaluate the efficacy, results, and complications of transphyseal technique of anterior cruciate ligament (ACL) reconstruction in prepubertal patients and to assess a possible influence of children's growth on the outcome. METHODS Between 2005 and 2009, 22 (16 boys and 6 girls) prepubescent patients, Tanner stage 1 and 2, underwent ACL reconstruction and the follow-up 6, 12, and 24 months after surgery and after growth plate closure. The average age of the girls was 11.2 years, and of the boys, 12.3 years. The average follow-up period was 77.2 months. Clinical outcome was evaluated by Lysholm, Tegner, and International Knee Documentation Committee (IKDC) objective and subjective knee scores. Standard radiograms were performed for potential axial growing disturbance. RESULTS The average follow-up period was 77.2 months (range, 54 to 102 months), and IKDC subjective scores changed from 58 (range, 44 to 69) before surgery to 87 (range, 86 to 87; P = .00) at 6 months, 93 (range, 88 to 97; P = .00) at 12 months, and 95 (range, 92 to -98; P = .5) at final examination. Lysholm score increased from 58 (range, 53 to 64) before surgery to 89 (range, 85 to 92; P = .00) at 6 months and 96 (range, 94 to 100; P = .00) at 12 months, 24 months (P = .9), and final examination (P = .8). Before injury, all patients were graded 7 on the Tegner scale. Nineteen athletes reached at least grade 7 and returned to the level of activity a mean of 9 months after the surgery. No patient had deformity or growth disturbances observed clinically. CONCLUSIONS Arthroscopic-assisted transphyseal ACL reconstruction in prepubescent patient is a promising technique, provided that all technical details are respected. It gives excellent subjective and objective knee scores and provides a very good function of the knee joint in the midterm period with no or only minor effect on the leg length. The rate of growth after surgery did not influence the results. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
BACKGROUND This paper presents the outcomes of treatment of AO Type C distal radius fractures using LCP plates and K-wires. The analysis focused on comparison of movement range and global grip strength between the operated limb and the healthy one. MATERIAL AND METHOD The study involved 60 patients treated in the Regional Specialist Hospital in Zgierz in the period 2008-2013. LCP plates were used in 31 cases and fixation with K-wires was employed in 29 patients. The movement range and grip strength were evaluated in line with the standards of orthopaedic examination, using a goniometer and a dynamometer. X-ray imaging was used to assess the bony anatomy. The results were subsequently compared with those for the healthy limb. RESULTS The analyses showed that neither approach produced a grip strength equal to that of the healthy limb. In two cases of Type C1 fractures treated using LCP plates, the movement range was the same as that of the other upper limb; these results were not obtained in any of the patients with K-wires. Superior outcomes were recorded for LCP plates; however, the differences were not significant. Radiographs revealed a significant difference in the degree of restoration of the articular surface, with LCP plates producing superior outcomes. CONCLUSIONS 1. The use of LCP plates enables more accurate restoration of the bone anatomy in the distal radius. 2. The mobility and grip strength of the limb were similar for both therapeutic procedures provided appropriate radiographic outcomes had been achieved. 3. The functional deficit in both groups was strongest for rotational movements of the forearm and grip strength of the limb.

Abstract
BACKGROUND Cerebrally palsied children demonstrated limited independence while performing various activities of daily living, which is due to disorders of postural control. The best solution to improve postural control is the use of therapies that simultaneously focus on the sense of balance and motor skills. Such possibilities for patients with cerebral palsy are offered, for example, by hippotherapy. OBJECTIVE To assess the influence of hippotherapy on body balance in the sitting position among children with cerebral palsy. MATERIAL AND METHODS The study enrolled thirty-nine children aged 6-12 years with GMFCS level 1 or 2 spastic diplegia or spastic hemiplegia. The participants were divided into an intervention group (n=19) and a control group (n=20). Children from the intervention group attended 30 minutes of hippotherapy once weekly for 12 consecutive weeks. The Sitting Assessment Scale (SAS) was used to assess the patients' posture and balance. RESULTS Some children improved their posture and balance during the study. Generally, control of trunk and head position and function of arms were getting better, while footwork was the weakest. CONCLUSION Hippotherapy has positive effects on the position and function of individual parts of the body, thus making it possible for cerebrally palsied children to improve posture and the ability to maintain balance in the sitting position.

The use of calcium carbonate beads containing gentamicin in the second stage septic revision of total knee arthroplasty reduces reinfection rate. Knee 2016; 23:322-6. [PMID: 26796778 DOI: 10.1016/j.knee.2015.12.001] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2015] [Revised: 11/23/2015] [Accepted: 12/09/2015] [Indexed: 02/02/2023]
Abstract
BACKGROUND The aim of the study was to analyze effectiveness and safety of packing the medullary canal of the tibia and femur with Herafill (Heraeus Medical GmbH, Wehrheim, Germany), a void filler and antibiotic carrier, during second stage revision total knee arthroplasty (TKA) for periprosthetic joint infection (PJI). METHODS Two groups were formed of 28 consecutive patients during second stage revision TKA, comparable for gender and age. The study group received Herafill, while the control group did not. The average follow-up was 52 months (minimum 36 months). RESULTS No reinfections were observed in the study group, while five were seen in the control group. No other differences were observed between the study and control groups, including mean clinical KSS (Knee Society score) (67.4 and 68.4 points, respectively) and functional score (72.5 and 70.5 points respectively). No side effects related to the use of Herafill beads were noted. CONCLUSIONS Herafill packed into the tibial and femoral intramedullary canal during second stage of septic revision TKA is a reliable bone substitute, may reduce recurrence of infection and incorporates well with host bone. However, results after PJI treatment are less than optimal measured by KSSs as compared to patients who do not require revision.

NERVE ENDINGS AND VASCULAR SUPPLY IN SEMITENDINOSUS TENDON OF CEREBRAL PALSY CHILDREN. ACTA ORTOPEDICA BRASILEIRA 2015; 23:259-62. [PMID: 26981034 PMCID: PMC4775478 DOI: 10.1590/1413-785220152305142813] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
Objective: To evaluate the distribution of SP (substance P) and S-100 peptide immunoreactivity, as well as the vascular supply of tissues commonly used as grafts for anterior cruciate ligament (ACL) reconstruction. A second aim was to compare the above mentioned distribution in the semitendinosus muscle tendons of cerebral palsy (CP) patients with the semitendinosus muscle tendons and patellar tendons of patients without CP. Methods: The first group consisted of 14 children with cerebral palsy with a mean age of 11.7 years old. At the time of hamstring lengthening operation, a sample of semitendinosus muscle was taken for analysis. The second group comprised 20 patients treated for isolated ACL rupture of the knee (mean age 32 years old). Group three comprised ten patients in the mean age of 14.3 years old treated for recurrent lateral patellar dislocation, and from whom a sample of patellar tendon was obtained. Results: No statistically significant differences were demonstrated with regard to the amount of immunopositive nerve fibers expressing SP or S-100 in all 3 groups of patients. A significant difference was noted in the number of blood vessels between the adult and child semitendinosus muscles, but not between the semitendinosus muscles and patellar tendon of children. Conclusion: The number of nociceptors as well as proprioceptive fibers is similar in patients with CP and patients from a neurologically healthy population. Level of Evidence IV, Cases Series.
