Cerebrospinal fluid signal loss sign: assessment of a new radiological sign in lumbar spinal stenosis.

PURPOSE: Sedimentation sign was reported to have high sensitivity and specificity for diagnosis of lumbar spinal stenosis (LSS). We aimed to determine cerebrospinal fluid signal loss (CSFSL) at the intervertebral disc levels in the sagittal plane using a numerical scoring system and to evaluate the diagnostic value of this method in differential diagnosis of LSS and non-specific low back pain (LBP) and compare it with SS. MATERIALS AND METHODS: We included consecutive patients between 50 and 80 years old, with lumbar spinal MRI examination in our institution. These patients were divided into two groups as LSS and LBP, according to symptoms and radiological findings. CSFSL sign was evaluated for both groups by two radiologists independently, using MR images. Sensitivity and specificity of both signs were calculated. RESULTS: A total of 406 patients (98 LSS and 308 non-specific LBP) were included. SS and CSFSL sign had a sensitivity of 90.8% and 82.7% and specificity of 75.4% and 84.1% in the whole cohort, respectively. When patients were grouped by dural sac cross-sectional areas (CSA), sensitivity and specificity of SS were 100% and 4.4%, 87.5% and 31.8%, and 41.7% and 76%, respectively, and sensitivity and specificity of CSFSL sign were 95.7% and 11.1%, 75% and 77.3%, and 16.7 and 92% for severe (CSA < 80 mm2), moderate (CSA: 80-100 mm2), mild (CSA: 100-120 mm2) radiologic stenosis, respectively. In moderate stenosis, accuracies of SS and CSFSL sign were 76.3% and 55.3%, respectively. CONCLUSION: CSFSL sign might be used to distinguish LSS from LBP and unlike SS it is successful in moderate stenosis.

Excessive extremity shortness due to septic arthritis : Case report of treatment with two surgical procedures.

Septic arthritis is a common joint infection in neonates and young children. Since osteoarticular infections cause permanent disability in bones and joints, they should be treated appropriately as soon as possible. If there is a delay in starting treatment it can cause severe morbidity. It is most common in the hip and shoulder joints. In this article the surgical treatment process and postoperative clinical status of a 35-year-old patient with severe coxarthrosis and 12 cm femoral shortening due to septic arthritis are reported. To avoid damage to neurovascular structures an extremity lengthening procedure was performed first, followed by a total hip replacement. In order to complete the distraction and consolidation phase in one session and to reduce complications, a growing intramedullary nail was selected. As a result of the surgical interventions, the complaints of the patient in the hip joint and the limping due to shortness of the leg decreased and the performance of activities of daily living was improved.

The importance of glenoid version in patients with anterior dislocation of the shoulder.

BACKGROUND: Although increased retroversion of the glenoid has been shown to be an important factor in posterior instability of the shoulder, there are few studies reporting glenoid bone structure as a risk factor in anterior dislocation of the shoulder. This study aimed to compare glenoid version in patients with anterior dislocation of the shoulder and individuals in a control group with no shoulder problems before undergoing computed tomography and to assess a possible relationship between demographic characteristics and glenoid version angle. METHODS: The study group comprised 63 patients (12 women and 51 men; mean age, 35.71 years) with 1 or multiple unilateral anterior dislocations of the shoulder (dislocated group), whereas 63 individuals (11 women and 52 men; mean age, 35.38 years) with no history of shoulder complaints and no signs of instability constituted the control group. The glenoid version angle was measured on an axial cut of the computed tomography scan. RESULTS: The glenoid version angles on the dislocated side in the study group were significantly more anteverted than those of the dominant (P < .001) and nondominant (P = .023) shoulders of the control group. The version angles of dislocated shoulders significantly differed from those of nondislocated shoulders of both men (P = .041) and women (P = .049). There was no significant relationship between the glenoid version angle on the dislocated side and dislocation mechanism (P = .883), age group (P = .356), or number of dislocations (P = .971). CONCLUSIONS: Glenoid version is an important factor for the development of anterior dislocation of the shoulder.

Efficacy of intraarticular application of ketamine or ketamine-levobupivacaine combination on post-operative pain after arthroscopic meniscectomy.

PURPOSE: To evaluate the efficacy of intraarticular injection of ketamine or ketamine plus levobupivacaine on post-operative analgesia in patients undergoing arthroscopic meniscectomy. METHODS: A prospective, randomized, double-blind study was performed on 60 patients aged 18-65 years who planned to undergo elective arthroscopic meniscectomy. The patients were divided into three groups: the ketamine group (n = 20) received 1.0 mg/kg of intraarticular ketamine in 20 ml of normal saline, the ketamine-levobupivacaine group (n = 20) received 0.5 mg/kg of intraarticular ketamine plus 50.0 mg of 0.25 % levobupivacaine in 20 ml of normal saline, and the control group (n = 20) received 20 ml of intraarticular normal saline. A visual analogue scale (VAS) was used to determine the efficacy of analgesia at 1, 2, 4, 6, 8, 12, and 24 h post-operatively. RESULTS: There were statistically significant differences in the median VAS scores among the three groups according to Bonferroni adjustment at all time points (p < 0.01), with the exception of 6 and 24 h post-operatively. The median VAS scores at 1, 2, and 4 h post-operatively were higher in the control group than in the two treatment groups (p < 0.001). The median VAS scores in the control group at 1, 2, 4, 6, 8, and 12 h post-operatively and those in the ketamine group at 4, 8, and 12 h post-operatively were significantly higher than those in the ketamine-levobupivacaine group (p < 0.05). CONCLUSION: Intraarticular ketamine provides effective post-operative analgesia. Addition of intraarticular levobupivacaine to ketamine may provide better amelioration of pain after outpatient arthroscopic meniscectomy.

Assessment of Postoperative Tendon Quality in Patients With Achilles Tendon Rupture Using Diffusion Tensor Imaging and Tendon Fiber Tracking.

Although pre- and postoperative imaging of Achilles tendon rupture (ATR) has been well documented, radiographic evaluations of postoperative intratendinous healing and microstructure are still lacking. Diffusion tensor imaging (DTI) is an innovative technique that offers a noninvasive method for describing the microstructure characteristics and organization of tissues. DTI was used in the present study for quantitative assessment of fiber continuity postoperatively in patients with acute ATR. The data from 16 patients with ATR from 2005 to 2012 were retrospectively analyzed. The microstructure of ART was evaluated using tendon fiber tracking, tendon continuity, fractional anisotropy, and apparent diffusion coefficient values by way of DTI. The distal and proximal portions were measured separately in both the ruptured and the healthy extremities of each patient. The mean patient age was 41.56 ± 8.49 (range 26 to 56) years. The median duration of follow-up was 21 (range 6 to 80) months. The tendon fractional anisotropy values of the ruptured Achilles tendon were significantly lower statistically than those of the normal side (p = .001). However, none of the differences between the 2 groups with respect to the distal and proximal apparent diffusion coefficient were statistically significant (p = .358 and p = .899, respectively). In addition, the fractional anisotropy and apparent diffusion coefficient measurements were not significantly different in the proximal and distal regions of the ruptured tendons compared with the healthy tendons. The present study used DTI and fiber tracking to demonstrate the radiologic properties of postoperative Achilles tendons with respect to trajectory and tendinous fiber continuity. Quantifying DTI and fiber tractography offers an innovative and effective tool that might be able to detect microstructural abnormalities not appreciable using conventional radiologic techniques.

Can hyperbaric oxygen be used to prevent deep infections in neuro-muscular scoliosis surgery?

BACKGROUND: The prevalence of postoperative wound infection in patients with neuromuscular scoliosis surgery is significantly higher than that in patients with other spinal surgery. Hyperbaric oxygen has been used as a supplement to treat postsurgical infections. Our aim was to determine beneficiary effects of hyperbaric oxygen treatment in terms of prevention of postoperative deep infection in this specific group of patients in a retrospective study. METHODS: Forty two neuromuscular scoliosis cases, operated between 2006-2011 were retrospectively reviewed. Patients who had presence of scoliosis and/or kyphosis in addition to cerebral palsy or myelomeningocele, postoperative follow-up >1 year and posterior only surgery were the subjects of this study. Eighteen patients formed the Hyperbaric oxygen prophylaxis (P-HBO) group and 24, the control group. The P-HBO group received 30 sessions of HBO and standard antibiotic prophylaxis postoperative, and the control group (received standard antibiotic prophylaxis). RESULTS: In the P-HBO group of 18 patients, the etiology was cerebral palsy in 13 and myelomeningocele in 5 cases with a mean age of 16.7 (11-27 yrs). The average follow-up was 20.4 months (12-36mo). The etiology of patients in the control group was cerebral palsy in 17, and myelomeningocele in 7 cases. The average age was 15.3 years (8-32 yrs). The average follow-up was 38.7 months (18-66mo). The overall incidence of infection in the whole study group was 11.9% (5/42). The infection rate in the P-HBO and the control group were 5.5% (1/18), and 16.6% (4/24) respectively. The use of HBO was found to significantly decrease the incidence of postoperative infections in neuromuscular scoliosis patients. CONCLUSION: In this study we found that hyperbaric oxygen has a possibility to reduce the rate of post-surgical deep infections in complex spine deformity in high risk neuromuscular patients.

Does reduction mammaplasty revert skeletal disturbances in the vertebral column of patients with macromastia? A preliminary study.

BACKGROUND: Enlarged breasts are associated with many physical and psychological symptoms. It is important to use objective criteria in documenting physical changes of a patient's body due to enlarged breasts and the benefits of surgery. This preliminary study aimed to determine whether the reduction mammaplasty procedure changes the angles of cervical lordosis, thoracic kyphosis, and lumbar lordosis. METHODS: The study population consisted of 22 patients who underwent breast reduction surgery. All the patients had lateral cervicothoracolumbar radiographs taken preoperatively and at least 2 months postoperatively. Cervical lordosis, thoracic kyphosis, and lumbar lordosis angles, as well as sagittal balance, were examined. The body mass index (BMI), breast tissue volume, and excised tissue amount of each patient were recorded. RESULTS: All the patients had increased cervical lordosis and thoracic kyphosis angles preoperatively, and the angles were significantly decreased postoperatively. Of the 22 patients, 7 had decreased and 8 had increased lumbar lordosis angles. All the lordosis angles showed significant improvement at the last examination. Seven patients had disturbed sagittal balance preoperatively, and all had normal sagittal balance postoperatively. Preoperative total breast tissue volume was positively correlated with the differences in cervical lordosis angles, BMI, preoperative cervical lordosis angles, and cervical lordosis angles. CONCLUSION: Hypertrophic breasts are not only a cosmetic but also a functional problem complicated by pathologic conditions in the vertebral column such as increased cervical lordosis, thoracic kyphosis, and increased or decreased lumbar lordosis. Breast reduction may improve these pathologic angles. Reducing the nonphysiologic weight of enlarged breasts located anterior to the main axis of the body may correct pathologic angulation and disturbed sagittal balance of the vertebral column.

PCA-pump for analgesia following pediatric scoliosis surgery: bolus administration with/without basal infusion.

OBJECTIVES: The aim of this study is to compare the use of two different opioid delivery systems (bolus PCA with/without basal infusion) to control postoperative pain and evaluate the side effect profile in pediatric patients undergoing scoliosis surgery. PATIENTS AND METHODS: 38 patients who underwent posterior spinal fusion for adolescent idiopathic scoliosis were included in the study. Patients were randomly divided into 2 groups by the computer. Patients who received only bolus PCA were named Group 1, and patients who received bolus PCA with basal infusion were named Group 2.Morphine consumption, postoperative pain assessmentduring rest, movement and coughing with numeric rating scale (NRS) and the Wong -Baker pain scale, heart rate and average blood pressure, sedation levels withRamsey sedation scale and side effects such as nausea, vomiting, itching, desaturation, and urinary retention were recorded. RESULTS: Total mean morphine consumption (mg) was 32.7 ± 9.7 in Group 1 and 43.4 ± 9.1 in Group 2. The mean morphine consumption (mg) at 12-24 hours and 0-48 hours in Group 1 was statistically lower than Group 2 (p = 0.001). There was no significant difference between the groups in terms of median NRS scores (p = 0.55). There was no statistically significant difference in the evaluation of the groups in terms of Wong-Baker pain scale. Wong-Baker pain scale is p:0.66 at the 2nd hour, p:0.951 at the 12th hour and p:0.467 at the 24th hour.There was no statistically significant difference in Ramsay Sedation Scale evaluation between groups during each follow-up time (p > 0.05). The Ramsay Sedation Scale was p: 0.94 at the 2nd hour, p:1.0 at the 12th hour, and p:1.0 at the 24th hour. The duration of vomiting between 0-2 h, 2-24 h and 0-48 h was higher in Group 2 (p = 0.001, p = 0.024, p = 0.001). CONCLUSION: The two administration settings of morphine sulphate by PCA pump have shown to be equally effective in the treatment of postoperative pain following PSF. In addition, PCA with basal infusion administration causes more opioid consumption and more systemic side effects. Therefore, the use of only bolus PCA in pediatric scoliosis surgery should be encouraged. LEVEL OF EVIDENCE: Level II, Randomized Controlled Trial.

The use of intralaminar screws in patients with spinal deformity.

STUDY DESIGN: Retrospective study. OBJECTIVE: To demonstrate that intralaminar screws (ILS) can be used as supplements in spinal deformity surgery in the thoracic and lumbar levels in pediatric and adult patients. SUMMARY OF BACKGROUND DATA: Rigid posterior fixation of the spine is generally accomplished using pedicle screws, hooks, or wires. ILSs are useful tools when other spinal fixation techniques have failed or the bony anatomy precludes hook or screw placement. MATERIALS AND METHODS: All spinal deformity patients (primary/revision) operated between 2007 and 2011 were retrospectively reviewed. The patients with ILS were included in the study. The anteroposterior and lateral standing x-rays were evaluated in terms of preoperative and postoperative coronal and sagittal deformities. The number and level of ILS, intraoperative complications, and postoperative complications were noted. RESULTS: There were 20 patients (12 male and 8 female). The mean age was 21.75 years. The mean follow-up period was 17.4 months. Fifty-seven ILS were inserted. Seventeen screws were used in the uppermost to lowermost levels. Forty screws were used in the middle. There was 1 lamina fracture and screw pull out (1.75%). There were 3 canal violations (corrected intraoperative) and 2 instrument prominences which required implant removal. The mean preoperative/postoperative cobb angles were 78.5 degrees/27.8 degrees and the mean preoperative/postoperative kyphosis angles were 57.2 degrees/32.5 degrees, respectively. The loss of correction was 1.2 degrees. There were no neurological deficits and no instrument failures. CONCLUSIONS: ILS are safe and effective when used in deformity correction. However, biomechanical studies and randomized controlled trials are needed to conclude whether ILS will be considered a first-line technique, or will remain a technique for salvage situations.

Convex short segment instrumentation and hemi-chevron osteotomies for Putti type 1 thoracic hemivertebrae: a simple treatment option for patients under 5 years old.

STUDY DESIGN: A case series depicting the results of a novel surgical technique. OBJECTIVE: To prove that a minimally invasive surgical technique can effectively control and even correct congenital scoliosis caused by a fully segmented hemivertebra. SUMMARY OF BACKGROUND DATA: Congenital hemivertebrae have been treated by anterior and posterior growth arrest with/without fusion, anterior and posterior hemivertebrectomy, transpedicular hemivertebra excision, and transpedicular hemiepiphysiodesis. These approaches are complex and require experience. There is a need for a simple treatment method to treat these deformities. METHODS: Twelve patients under 5 years of age with Putti type1 hemivertebrae were treated by posterior convex short segment instrumentation, partial chevron osteotomies, and fusion. Scoliosis, segmental scoliosis, kyphosis, segmental kyphosis, trunk shift were measured both preoperatively and postoperatively. RESULTS: The mean correction of the segmental curve was 6 degrees (21%) which was maintained at the latest follow-up. The average final correction of the main curve was 23%. The trunk shift was 1.8 cm (range, 1-3 cm) preoperative and 1.4 cm (range, 0-2.5 cm) at the latest follow-up. The segmental angle of kyphosis averaged 11 degrees (range, -12 to 20 degrees) preoperative, and 14 degrees (range, 0-29 degrees) at the latest follow-up assessment. The values of the total thoracic kyphosis (T2-T12) were 29.5 degrees (range, 10-46 degrees) preoperative, 31 degrees (range, 10-44 degrees) postoperative, and 32 degrees (range, 16-45 degrees) at the last follow-up resulting in a mean improvement of 2 degrees. This improvement continued at the latest follow-up with a mean increase of 3 degrees. CONCLUSIONS: Transpedicular instrumentation is ideal for early correction in young children. The new posterior approach is much less invasive than the combined approaches or other posterior vertebrectomies and is well tolerated even in very young patients. The fusion segment is kept short. The deformities seem to stop progressing and this can avoid development of severe local deformities and secondary curves.

The effects of diabetes on symptoms of carpal tunnel syndrome treated with mini-open surgery.

This study aimed to evaluate the influence of type II diabetes mellitus (DM) on the postoperative outcomes of mini-open carpal tunnel syndrome (CTS) surgery. A total of 99 hands in 74 patients were included in the study. Of these, 36 patients (54 hands) had type II DM (Group A), and 38 patients (45 hands) had idiopathic CTS (Group B). Mini-open carpal tunnel release surgery was performed on all the hands. The night pain, weakness, paraesthesia, numbness complaints were significantly improved in both groups after surgery. However, thenar atrophy was improved significantly only in group A. Night pain, weakness, paraesthesia, numbness, and pillar pain were significantly worse in Group A than in Group B on postoperative examination. Postoperatively, Tinnel and Phalen tests were positive in 32 hands in Group A and 6 hands in Group B. Persistence of symptoms in diabetic patients was found to be more prevalent compared to non-diabetic controls after mini-open carpal tunnel release.

Easy retrieval of polyaxial tulip-head pedicle screws by "U" rod technique.

The number of fusion surgeries increase each year which also increase the need for implant removal. In some cases, it can be extremely hard to remove a pedicle screw especially when there is a mismatch of the screw and the screwdriver. Also the screwdrivers can be contaminated during the operation, and this will cause a delay till the instruments are re-sterilized. There is a need for the removal of screws without special instruments. We describe a method for removing tulip-head polyaxial pedicle screws without special instruments. The screws are removed using an Allen key, a rod bender and a "U" shaped rod. We successfully removed 76 screws in 11 recent cases without any complications. The "U" rod technique is a simple and useful technique for the removal of tulip-head polyaxial screws.

HIGH TIBIAL OSTEOTOMY USING A LOCKING TITANIUM PLATE WITH OR WITHOUT AUTOGRAFTING.

OBJECTIVE: To postoperatively evaluate knee scores, radiological assessment results, deficit correction, patellar height change, bone healing time, and weight bearing time in patients undergoing high tibial osteotomy (HTO) with/without autologous iliac bone grafting. METHODS: This retrospective examination of treated controls from a randomized controlled study included 63 knees of 58 patients aged 46-59 years who underwent HTO with locking open wedge osteotomy plates. The patients were divided into two groups: Group A, HTO with autologous iliac bone grafts (n = 31); and Group B, HTO without autologous iliac bone grafts (n = 32). Clinical and radiological data were evaluated prospectively at the preoperative consultation and again at 6, 9, and 12 weeks, 6 months, and 1 year after the surgery (and annually thereafter). RESULTS: There were no significant intergroup differences in the radiological assessment, deficit correction, patellar height change, bone-healing time, and weight-bearing time at any time after surgery. The knee scores changed positively in both groups (p < 0.001). CONCLUSIONS: There was no difference in the results of patients undergoing HTO with open wedge osteotomy titanium locking plates with or without autografting, and comorbidities resulting from autografts were eliminated with the use of locking plates.

OBJETIVO: Avaliar escores de joelho, resultados da avaliação radiológica, correção de déficits, alteração da altura patelar, tempo de consolidação óssea e tempo para apoio de peso no pós-operatório em pacientes submetidos à osteotomia tibial alta (OTA) com ou sem enxerto autólogo de osso ilíaco. MÉTODOS: O exame retrospectivo de controles tratados em estudo randomizado e controlado foi realizado em 63 joelhos de 58 pacientes com idade entre 46 e 59 anos submetidos a OTA com placas bloqueadas de titânio em cunha aberta. Os pacientes foram divididos em dois grupos: Grupo A, OTA com enxerto de osso ilíaco autólogo (n = 31) e Grupo B, OTA sem enxerto autólogo de osso ilíaco (n = 32). Os dados clínicos e radiológicos foram avaliados prospectivamente na consulta pré-operatória e 6, 9 e 12 semanas e 6 meses e 1 ano após a cirurgia (e depois disso, anualmente). RESULTADOS: Não houve diferenças significativas quanto a avaliação radiológica, correção de déficit, mudança de altura da patela, tempo de cicatrização óssea e tempo para apoio de peso entre os dois grupos em nenhum momento após a cirurgia. Os escores de joelho mudaram positivamente em ambos os grupos (p < 0,001). CONCLUSÕES: Não houve diferença nos resultados dos pacientes submetidos a OTA com placas bloqueadas de titânio em cunha aberta com e sem autoenxerto, e as comorbidades resultantes dos autoenxertos foram eliminadas com o uso de placas bloqueadas.

Biomechanical comparison of a new handy tension band with malleolar screw, bicortical screw and conventional tension band for the fixation of transverse medial malleolar fractures.

OBJECTIVES: This study aims to compare the biomechanical features of a new handy tension band with the malleolar screw, bicortical screw and conventional tension band for the fixation of transverse medial malleolar fractures. MATERIALS AND METHODS: This study used 20 Kirschner wires, five cerclage wires, six double-hole U pins, six cortical screws, six malleolar screws, three malleolar clamps and one osteotomy set. A total of 24 tibias of two-year-old cows were obtained and stripped from soft tissue. Each tibia was cut with an electric saw at 15 cm proximal to the tibiotalar joint surface and the proximal tibia sections were discarded. A transverse fracture line was created with an osteotome on the medial malleolus. The tibias were separated into four groups with six tibias in each group. The distal tibia medial malleolar transverse fragments were fixed under guidance of fluoroscopy with the malleolar screw, bicortical screw, conventional tension band and the new handy tension band. RESULTS: In the application of both transverse and axial force, the new handy tension band resisted higher forces in respect of catastrophic damage force being more resistant compared to the bicortical screw, malleolar screw, and conventional tension band. However, in respect of the 2 mm displacement force of the forces applied in the axial and transverse sections, no difference was determined between the handy tension band and the other three implants. CONCLUSION: The new handy tension band seems to be more successful when biomechanically compared with the other implants.

[The prevalence of low back pain and risk factors among adult population in Afyon region, Turkey]. / Afyonkarahisar ilinde eriskinlerde bel agrisi sikligi ve etkileyen faktörler.

OBJECTIVES: This study was designed to determine the prevalence of and risk factors for low back pain (LBP) in a sample of Turkish population among adults living in the Afyon region, Turkey. METHODS: A field screening investigation was performed in a total of 75 areas including the city center, 18 districts, and 57 associated small municipalities. Adequate sample size was determined as 1,990 and a total of 2,035 individuals (1,194 females, 841 males) were enrolled. Participants were inquired about age, occupation, sex, height, weight, history of LBP, hypertension, diabetes, and smoking. Depression symptoms were evaluated using the Symptom Checklist-90-Revised. RESULTS: The prevalence of lifetime LBP was 51%, and the prevalence of chronic LBP was 13.1%. Overall, 63.2% of women and 33.8% of men had LBP at least once in their lives (p=0.001). With regard to occupation, the highest incidence of LBP was seen in housewives (64.2%; p=0.0001), whose age and body mass index (BMI) were also higher compared to employed women. Depression (p=0.016) and increased BMI (p=0.000) were found to increase the risk for LBP, whereas smoking, hypertension, or diabetes were not correlated with the prevalence of LBP. Poverty was found to be the leading cause (39.7%) for not presenting to a physician. CONCLUSION: Among risk factors reported for LBP, many are also effective in Turkish population. Special attention should be given to the education of housewives in terms of low back protection, healthy nutrition, and family planning. Poverty seems to be a significant barrier to patient presentation to physicians, requiring extended social security coverage.

[Hip rotation degrees, intoeing problem, and sitting habits in nursery school children: an analysis of 1,134 cases]. / Anaokulu çocuklarinda kalça rotasyon dereceleri, içe dönük yürüme sorunu ve oturma aliskanliklari: 1134 olgunun analizi.

OBJECTIVES: We investigated hip rotation degrees, frequency of intoeing problems, and sitting habits in nursery school children and the relationship between these parameters. METHODS: The study included 1,134 children (612 boys, 522 girls), aged between three to six years, attending 26 nursery schools in the central area of Afyon. First, informed consent was obtained from the parents and a questionnaire was administered about demographic data and sitting habits of the children. Then, the children were examined in lower underwear. Foot progression angles were determined and progression to midline during walking was evaluated as intoeing. Internal and external rotation degrees of the hips were measured using a goniometer in prone and supine positions. RESULTS: In girls, internal rotation of the hip was nearly 13 degrees greater in the prone position, and 9 degrees greater in the supine position compared to those of the boys. Intoeing was detected in 67 children (5.9%), 76.1% being bilateral. The girl-to-boy ratio was 2.4/1. Intoeing problem originated from the femur in 74.6%, and from the tibia in 25.4%. Compared to normal children, intoeing was associated with a greater internal rotation and a smaller external rotation of the hip. Overall, 36.7% had a crossed-leg sitting habit, and 63.3% had a television sitting habit. The latter was more frequent in intoeing children (p=0.001). CONCLUSION: Although hip rotation degrees in our study were similar to those reported in the literature, higher hip internal rotation degrees were found especially in girls. Television sitting which is a frequently preferred position among nursery school children was significantly prevalent in intoeing children.

IS RDW A PREDICTIVE PARAMETER FOR CUBITAL TUNNEL SYNDROME PATIENTS REQUIRING SURGERY?

OBJECTIVE: The aim of this study was to investigate whether haemogram parameters are predictive factors for both the severity of the disease and a decision in favor of surgical treatment in patients with an established diagnosis of cubital tunnel syndrome (CuTS) . METHODS: The medical files of patients with a diagnosis of CuTS who were followed-up conservatively (n=92) or surgically treated (n=92) were retrospectively screened and the haemogram parameters were recorded . RESULTS: The receiver operating characteristic (ROC) curve analysis revealed an area of 0.665 under the curve, with 76.3% sensitivity and 84.8% specificity at the cut-off of a red cell distribution width (RDW) level grater than 15.45%. RDW levels higher than 15.5%, electromyography (EMG) severity, and a clinical score higher than three were found to be independently associated with surgery . CONCLUSION: An elevated RDW value was related to the severity of the electromyogram. RDW may, therefore, be a useful independent predictor for the decision to surgical treatment of CuTS.

Using a Combination of Intralaminar and Pedicular Screw Constructs for Enhancement of Spinal Stability and Maintenance of Correction in Patients With Sagittal Imbalance: Clinical Applications and Finite Element Analysis.

STUDY DESIGN: Case series and finite element analysis. OBJECTIVE: To report the clinical results of using intralaminar screw-rod (ILS) constructs as supplements to regular pedicle screw (PS) constructs in "high risk for implant failure" patients and to report the results of a finite element analysis (FEA) of this new instrumentation technique. SUMMARY OF BACKGROUND DATA: Despite advances in surgery and implantation techniques, osteoporosis, obesity, revision surgeries, and neuromuscular conditions (such as the Parkinson disease) are challenges against achieving solid arthrodesis and maintaining correction. Additional fixation strategies must be considered in these patients. There is only one study in the literature suggesting that ILS can be used as alternative anchor points and/or to increase fixation strength in conjunction with the PSs. MATERIALS AND METHODS: Five patients (3 male and 2 female) with mechanical comorbidities underwent PS+ILS to treat sagittal imbalance. In radiologic analysis, thoracic kyphosis, lumbar lordosis, and sagittal vertical axis were analyzed. FEA of ILS augmentation technique were carried out.Four different models were created: (1) the full-construct model with ILS+PS 2 levels above and below the osteotomy of T10; (2) only PS 2 levels above and below T10; (3) ILS+PS 1 level above and below the osteotomy; and (4) short-segment PS with only PSs 1 level above and below the osteotomy. The stress/load distributions on the implants in vertebrae were analyzed. RESULTS: The mean age of the patients included in this study was 41 years and the mean follow-up was 28.2 months. A total of 87 PSs and 39 ILSs were used. Both sagittal vertical axis and kyphosis angles showed significant improvements maintained at the latest follow-up. No pseudarthrosis or instrumentation failures were observed. FEA indicated that addition of ILS construct to a PS construct enabled decreased load bearing and increased implant life. CONCLUSIONS: Addition of an ILS construct to PS construct decreases osteotomy line deformation and reduces stress on pedicle fixation points, and the combination improves fixation stability over the conventional PS-rod technique.
