THE EFFECT OF CONSUMING YOGHURT ON THE SALIVARY PH OF MILDLY MENTALLY RETARTED CHILDREN

The percentage of people with disabilities in Indonesia is 56% and the prevalence of dental caries in children with disabilities reaches 82.6%. One alternative to prevent dental caries is by consuming probiotic drinks such as yogurt. Yoghurt is sour milk produced by fermenting milk and the group of probiotic products most accepted by children. Objective: This study aims to determine the effect of consuming yogurt on the pH of saliva of children with mild deformities SLB Patriot Tasikmalaya City. Methods: The type of research used is a quasi experiment research method with a one group pre-test and post-test research design with a sample of 20 mildly retarded children. The research measuring instrument used a pH meter, and the data was analyzed using a paired sample t-test. Results: Based on the results of the paired sample t-test statistical test, the p-value = 0.001 (p < 0.05) means that there is an effect of consuming yogurt on the pH of the saliva of mildly retarded children of SLB Patriot Tasikmalaya City. Conclusion: Consuming yogurt regularly for seven days can increase salivary pH in mildly retarded children.

Necessity of posterior osteotomies for mild flexible cervical deformity correction.

Correction of mild flexible cervical deformity (CD) via the posterior approach has been described with and without the use of posterior osteotomies (POs), despite a lack of clarity regarding their necessity or risks. The purpose of this study was to determine whether the use of POs when correcting mild flexible CD leads to improved clinical or radiographic outcomes, as well as defining the relative risks in utilizing them. A prospective multicenter registry of operative CD patients was analyzed. Inclusion criteria were cervical kyphosis > 10°, cervical scoliosis > 10°, cervical sagittal vertical axis (cSVA) > 4 cm, or chin-brow vertical angle > 25°. Mild deformity was defined by a cSVA of 3-5 cm and/or kyphosis < 15°. Flexibility was defined by a C2-7 angular change > 5° on preoperative flexion/extension radiographs. Patients who received a posterior column osteotomy (PCO) (Ames grades 1 and 2) were compared with patients who did not undergo a PCO (noPCO) as well as those who underwent a three-column osteotomy (3CO) (Ames grades 3-6). Ninety-five patients (33 PCO, 49 noPCO, 13 3CO) met the inclusion criteria. Both the number of levels fused (9.2 vs 7.7, p = 0.001) and the estimated blood loss (EBL) (1027 vs 486 mL, p = 0.012) were higher in the PCO cohort. Patients in the noPCO group were more likely to have a cervical apex of kyphosis (71.1%, p = 0.046), while those undergoing 3COs were more likely to have a thoracic apex (58.3%, p = 0.005). Preoperative cSVA (PCO vs noPCO: 45.4 vs 37.9 cm, p = 0.084), T1 slope (32.5° vs 29.6°, p = 0.376), C2-7 lordosis (-8.9° vs -9.2°, p = 0.942), and modified Japanese Orthopaedic Association (mJOA) score (13.4 vs 13.5, p = 0.854) were similar; however, both Neck Disability Index (NDI) (55.6 vs 42, p = 0.002) and numeric rating scale (NRS) neck (7.2 vs 5.8, p = 0.028) scores were higher in the PCO group before surgery. When adjusting for the use of an anterior approach, there was no significant difference in 1-year postoperative cSVA (35.7 and 35.6 cm, respectively; p = 0.969), C2-7 lordosis (13.7° and 10.1°, respectively; p = 0.393), and patient-reported outcome measures (NRS, NDI, and mJOA) between the PCO and noPCO groups. Two-year radiographic outcomes were largely similar, except for C2 slope, which was higher in the PCO group (29.1° vs 18°, p = 0.026). The overall complication rates progressively increased with more complex osteotomy use (noPCO 68.8% vs PCO 71.9% vs 3CO 75%) but did not reach significance (p = 0.063). The use of POs for mild flexible adult CD may not be necessary to achieve desirable radiographic correction. They are associated with greater EBL and fusion burden. Further studies are needed to fully delineate the risks of adverse events for various types of osteotomies.

Radiographic Alignment in Deformity Patients Treated With Personalized Interbody Devices: Early Experience From the COMPASS Registry.

Literature supports the need for improved techniques to achieve spinopelvic alignment and reduce complication rates in patients with adult spinal deformity (ASD). Personalized interbody devices were developed to address this need and are under evaluation in the multicenter Clinical Outcome Measures in Personalized aprevo (circle R superscript) Spine Surgery (COMPASS (TM suprascript) registry. This report presents interim COMPASS pre- and postoperative sagittal alignment results and complication rates for a subcohort of COMPASS patients diagnosed and surgically treated for spinal deformity. COMPASS is a postmarket observational registry of patients enrolled either before or after index surgery and then followed prospectively for 24 months. Sagittal alignment was assessed with SRS-Schwab modifiers for pelvic incidence minus lumbar lordosis, pelvic tilt, and T1 pelvic angle. Summed SRS-Schwab modifiers were utilized to assign overall deformity status as mild, moderate, or severe. Complications were extracted from patient medical records. The study included 67 patients from 9 centers. Preoperative severe deformity was observed in 66% of patients. Index surgeries included implantation of a median of 2 personalized interbody devices by anterior, lateral, or transforaminal approaches and with a median of 8 posteriorly instrumented levels. Overall postoperative sagittal alignment improved with a significant decrease in the mean sum of SRS-Schwab modifiers that correlated strongly to improvements in pelvic incidence minus lumbar lordosis. Among 44 patients with preoperative severe overall deformity, 16 improved to moderate and 9 to mild deformity. Complications occurred for 13 patients (19.4%), including 1 mechanical complication requiring revision 9 months after surgery and none related to personalized interbody devices. This study demonstrates that ASD patients whose treatment included personalized interbody devices can obtain favorable postoperative alignment status comparable to published results and with no complications related to the personalized interbody devices. This study contributes to growing evidence that personalized interbody devices contribute to improved sagittal alignment in ASD patients by directly adjusting the orientation of adjacent vertebra.

Investigation of ground subsidence response to an unconventional longwall panel layout

Ground subsidence caused by extraction of longwall panels has always been a great concern all over the world. Conventional longwall mining system (CLMS) gives rise to wavy subsidence causing great damage to surface structures. A coal mine in Shanxi, China, utilizes a split-level longwall layout (SLL) for a sub-horizontal No. 8 coal seam to improve the cavability of mudstone interlayer and top coal. This layout, however, also produced unexpectedly favorable surface subsidence. Subsidence of No. 6 and No. 8 longwall panels was monitored while mining was conducted. Field instrumentation and numerical simulation were carried out. It is demonstrated that an asymmetric subsidence profile with stepped subsidence and cracks occurred on the tailgate side but relatively mild and smooth deformation on the other. Due to elimination of conventional parallelepiped gate pillar, No. 6 and No. 8 gobs were connected. Extraction of two SLL panels acted as one supercritical panel. The maximum possible subsidence was reached which lowers the likelihood of potential future secondary subsidence as underground gob fractures and voids have closed. Therefore, SLL is more favorable for post-mining land reuse as gobs are more consolidated underground.

Impact of preoperative age-adjusted sagittal imbalance on radiographic and clinical outcomes following 1-level minimally invasive transforaminal lumbar interbody fusion for degenerative spondylolisthesis.

Prior studies investigating the use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for treatment of degenerative lumbar conditions and concomitant sagittal deformity have not stratified patients by preoperative pelvic incidence (PI)-lumbar lordosis (LL) mismatch, which is the earliest parameter to deteriorate in mild sagittal deformity. Thus, the aim of the present study was to determine the impact of preoperative PI-LL mismatch on clinical outcomes and sagittal balance restoration among patients undergoing MI-TLIF for degenerative spondylolisthesis (DS). Consecutive adult patients undergoing primary 1-level MI-TLIF between April 2017 and April 2022 for DS with ≥ 6 months radiographic follow-up were included. Patient-reported outcome measures (PROMs) included the Oswestry Disability Index, visual analog scale (VAS), 12-Item Short-Form Health Survey (SF-12), and Patient-Reported Outcomes Measurement Information System at preoperative, early postoperative (< 6 months), and late postoperative (≥ 6 months) time points. The minimal clinically important difference (MCID) for PROMs was also evaluated. Radiographic parameters included PI, LL, pelvic tilt (PT), and sagittal vertical axis (SVA). Patients were categorized into balanced and unbalanced groups based on preoperative PI-LL mismatch according to age-adjusted alignment goals. Changes in radiographic parameters and PROMs were evaluated. Eighty patients were included (L4-5 82.5%, grade I spondylolisthesis 82.5%, unbalanced 58.8%). Mean clinical and radiographic follow-up were 17.0 and 8.3 months, respectively. The average preoperative PI-LL was 18.8° in the unbalanced group and -3.3° in the balanced group. Patients with preoperative PI-LL mismatch had significantly worse preoperative PT (26.2° vs 16.4°, p < 0.001) and SVA (53.2 vs 9.0 mm, p = 0.001) compared with balanced patients. Patients with preoperative PI-LL mismatch also showed significantly worse PI-LL (16.0° vs 0.54°, p < 0.001), PT (25.9° vs 18.7°, p < 0.001), and SVA (49.4 vs 22.8 mm, p = 0.013) at long-term follow-up. No significant radiographic improvement was observed among unbalanced patients. All patients demonstrated significant improvements in all PROMs (p < 0.05) except for SF-12 mental component score. Achievement of MCID for VAS back score was significantly greater among patients with preoperative PI-LL mismatch (85.7% vs 65.5%, p = 0.045). Although 1-level MI-TLIF did not restore sagittal alignment in patients with preoperative PI-LL mismatch, patients presenting with DS can expect significant improvement in PROMs following 1-level MI-TLIF regardless of preoperative alignment or extent of correction. Thus, attaining good clinical outcomes in patients with mild sagittal imbalance may not require addressing imbalance directly.

A simplified approach to discriminate between healthy subjects and patients with heart failure using cardiac magnetic resonance myocardial deformation imaging.

Left ventricular global longitudinal strain (LV-GLS) shows promise as a marker to detect early heart failure (HF). This study sought to (i) establish cardiac magnetic resonance imaging (CMR)-derived LV-GLS cut-offs to differentiate healthy from HF for both acquisition-based and post-processing techniques, (ii) assess agreement, and (iii) provide a method to convert LV-GLS between both techniques. A secondary analysis of a prospective study enrolling healthy subjects (n = 19) and HF patients (n = 56) was conducted. LV-GLS was measured using fast strain-encoded imaging (fSENC) and feature tracking (FT). Receiver operating characteristic (ROC) analyses were performed to derive and evaluate LV-GLS cut-offs discriminating between healthy, HF with mild deformation impairment (DI), and HF with severe DI. Linear regression and Bland-Altman analyses assessed agreement. Cut-offs discriminating between healthy and HF were identified at -19.3% and -15.1% for fSENC and FT, respectively. Cut-offs of -15.8% (fSENC) and -10.8% (FT) further distinguished mild from severe DI. No significant differences in area under ROC curve were identified between fSENC and FT. Bland-Altman analysis revealed a bias of -4.01%, 95% CI -4.42, -3.50 for FT, considering fSENC as reference. Linear regression suggested a factor of 0.76 to rescale fSENC-derived LV-GLS to FT. Using this factor on fSENC-derived cut-offs yielded rescaled FT LV-GLS cut-offs of -14.7% (healthy vs. HF) and -12% (mild vs. severe DI). LV-GLS distinguishes healthy from HF with high accuracy. Each measurement technique requires distinct cut-offs, but rescaling factors facilitate conversion. An FT-based LV-GLS ≥ -15% simplifies HF detection in clinical routine.

FREQUENCY AND RELATED FACTORS OF HALLUX VALGUS AMONG FEMALE SCHOOL TEACHERS

Background/Aim of Study: HV is a progressive, chronic deformity affecting the first metatarsophalangeal joint causing big toe lateral deviation and 1st metatarsal being medially deviated hence our objective is to calculate the frequency, factors associated with Hallux valgus and their rehabilitation. Methodology: Non-probability A convenient sampling technique among 273 females aged 20-60 years from Jhelum District was done. Self-administrated questionnaires were filled out, and pain was measured using VAS. The goniometer and Manchester scale were used to evaluate HV deformity. Results: The overall frequency of Hallux valgus was found to be 75.46%. 43.96% elder and 31.5% younger females. Mean age of participants was 42.95 ± 9.96. HV angle showed 24.9% were normal, 57.9% mild, 16.5% moderate, and 0.7% had severe deformity. The association of HV with BMI and shoe shape was statistically significant. No association was found between age, work experience, and heel height. Conclusions: HV abnormality was high in elders when compared with youngers. The severity for HV grading showed mild deformity with bilateral HV more frequent among female. Foot wear i–e shoe shape and BMI plays a substantial role in the development of HV.

Lower eyelid retraction repair using autologous auricular scapha cartilage.

To assess the efficacy of lower eyelid retraction surgery utilizing autologous auricular scapha cartilage (located within the anterior surface groove between the helix and anti-helix) and to present the surgical outcomes in a patient cohort. Medical records of 21 patients who underwent lower eyelid retraction surgery with scapha cartilage were retrospectively reviewed. Retractions, present for an extended duration (6months to 20years), exhibited 1mm or more inferior scleral show, attributed to prior lower eyelid blepharoplasty, facial palsy, or as a normal anatomical variation. Surgical interventions included lateral canthotomy, cantholysis, incision of the subtarsal conjunctiva-lower eyelid retractors, lower eyelid retractor lysis, cartilage graft suturing to the defect area without conjunctival cover, and tightening of the lateral canthal corner in all patients. A total of 29 eyelids in 21 patients underwent surgery without intraoperative complications. Over a mean follow-up period of 11months (range: 6-30months), lower lid retraction improved in 96.5% of eyelids. Postoperative margin-to-reflex distance measurements (MRD2) significantly decreased compared to preoperative values (p = 0.001; p < 0.01). Average improvements in MRD2-a (midpupil to lower lid) and MRD2-b (lateral limbus to lower lid) were 1.77 ± 0.80 and 2.04 ± 0.81, respectively (p = 0.001; p < 0.01). Four eyelids (4/29) required revision due to canthal corner loosening, with correction necessitating periosteal flaps. All four patients had previously undergone two or more repairs elsewhere. The graft was visible in two lids but did not require further revision. One patient experienced mild helix deformity at the donor site, which did not warrant additional intervention. In cases of lower lid retraction associated with middle/posterior lamellar shortening, utilizing an autologous auricular scapha cartilage spacer graft offers notable benefits. These advantages comprise straightforward harvesting with minimal donor site complications, stability without experiencing shrinkage, a softer texture in comparison to posterior cartilage, a concave shape that facilitates proper fitting on the globe, and its autologous nature.

Surgical Removal of Fat Nodules Formed in the Tear Trough After Autologous Fat Grafting.

Autologous fat grafting is a common treatment for tear trough deformities. This procedure involves a potential complication of fat nodule formation, leading to abnormal bulging of the lower eyelid. However, limited information exists about this complication, and an effective treatment is lacking. The present study aimed to present a novel surgical approach for the removal of fat nodules caused by autologous fat grafting in the tear trough. This retrospective study included 33 patients who underwent surgery for the removal of fat nodules formed after autologous fat grafting. The procedure was performed using a conjunctival approach, allowing exposure and removal of all fat nodules in the anterior septal space, with the method adapted according to the severity of the deformity. A total of 66 eyelids were treated surgically, including 30 (45.45%) with mild nodular deformity, 23 (34.85%) with moderate nodular deformity, and 13 (10.70%) with severe nodular deformity. A second surgical procedure was required on 3 eyelids (4.56%). The main complications of the surgery were conjunctival congestion (21.21%), and localized depression (18.18%), bruising (12.12%). Among the patients, 29 (87.88%) were satisfied and 4 (12.12%) were dissatisfied with the treatment results. Conjunctival approach surgery is an effective method of removing fat nodules formed after autologous fat grafting in the tear trough, with good results and high levels of patient satisfaction. This approach enables the effective management of a common complication of autologous fat grafting and may enable the wider application of autologous fat grafting in the periorbital region.

Hypermobility Among Adolescents and the Association With Spinal Deformities: A Large Cross-Sectional Study.

Adolescent idiopathic scoliosis and Scheuermann kyphosis are common spinal deformities (SD) among adolescents. The potential link between hypermobility and SD is a topic of debate. We aimed to investigate the prevalence of hypermobility and its association with SD. A cross-sectional analysis of records of 17-year-old subjects who were recruited into mandatory military service was conducted. Study population comprised 1,220,073 subjects. Prevalence rates were calculated for hypermobility and different categories of SD by severity, studying the strength of the association between hypermobility and SD. Of 1,220,073 subjects, 0.0111% exhibited hypermobility. Spinal deformities were identified in 10.5% of subjects. Specifically, 7.9% had mild SD, 2.4% had moderate SD, and 0.1% had severe SD. The overall association between hypermobility and SD showed an odds ratio of 2.31 (P < 0.001). Subgroup analyses revealed ORs of 1.226 (P = 0.041) for mild deformities, 5.783 (P < 0.001) for moderate deformities, and 4.01 (P = 0.002) for severe deformities. The association was stronger for moderate and severe SD. This study establishes a notable association between hypermobility and SD among adolescents. The findings highlight the importance of understanding this relationship, which could contribute to advancements in comprehending SD development. Additional research is warranted to expand upon these findings.

5-year Long-term Outcome of Unilateral Cleft Rhinoplasty in Patients with Secondary Nasal Deformity: Optimal Indication of Tajima Technique.

This study aimed to investigate the timing of and indications for the Tajima reverse U incision for correcting secondary unilateral cleft nasal deformities. Non-syndromic patients with secondary cleft lip and nasal deformity who received Tajima reverse-U incision rhinoplasty were grouped by age (4-13 years, n=56;13-18 years, n=22; >18 years, n=18) and severity of deformity (mild deformity, n=7; moderate deformity=22; severity deformity=67) during 5-year follow-up. Face-Q assessment, a rating scale, and nasal symmetry measurements were employed in this study. Ninety-six patients completed the FACE-Q assessment for the nose and nostril. The results showed higher satisfaction with nostril appearance 1-week after surgery (85.95±13.01) compared with pre-operation (79.72±11.89) and maintained 5-year follow-up (82.61±14.06). Significant differences were observed in five nasal parameters (nasal height ratio, one-fourth media part of nostril height ratio, nasal sill height ratio, columellar angle, and inner nostril height-to-width ratio (cleft)) for 1-week postoperatively and the corrected outcome of the Tajima technique was maintained 5 years after surgery in aged 4-13 years group. The same statistically significant changes were found in nasal sill height ratio in mild deformity group and nostril width ratio, one-fourth media part of nostril height ratio, columellar angle, and inner nostril height-to-width ratio (cleft) in moderate deformity group. The Tajima procedure was beneficial for preadolescent children and children with mild to moderate unilateral cleft nasal deformities.

Spontaneous Reduction in the Intermetatarsal Angle in Distal First Metatarsal Osteotomies with No Lateral Head Displacement in Hallux Valgus.

The outcomes of first metatarsal (M1) distal osteotomies in hallux valgus (HV) can be improved, especially for intermetatarsal angle (IMA) correction, which is mainly based on lateral displacement of the M1 head (i.e., translation) through the osteotomy. Conversely, there is a spontaneous reduction in the IMA in first metatarsophalangeal joint (MTP1) arthrodesis. But we do not know whether this can be applied to distal osteotomies. We propose a distal osteotomy, called 3D chevron, which combines supination and varization of the M1 head. This might realign soft tissues around the MTP1, potentially leading to a spontaneous reduction in the IMA by an analogous mechanism to MTP1 fusion. Therefore, our study aimed to assess whether spontaneous reductions in IMAs exist in distal M1 osteotomies in the absence of lateral translations of M1 heads. A prospective continuous series of 25 3D chevrons was performed. Two groups were formed during surgery. Patients requiring no M1 head lateral displacement were included in the "successful correction without translation" group, and patients requiring M1 head lateral displacement were included in the "failed correction without translation" group. Radiographic analysis was performed preoperatively and at 1 year postoperatively. Twenty-two women and three men, with a mean age of 44.8 ± 14.2 years and a mean body mass index of 22.6 ± 4.1 kg/m2, underwent follow-up at one year after surgery. The "successful correction without translation" group was composed of HV with milder deformities (13/25 HVs, median preoperative IMA = 13 (IQR 2)) compared to the "failed correction without translation" group (median IMA = 16 (IQR 2.25) p < 0.001). Spontaneous reductions in IMAs were observed in the "successful correction without translation" group, with a median decrease in the IMA of 6 degrees (CI95%[5.5; 8.0]; p < 0.001) between preoperative and 1-year radiographs. Distal osteotomies allow for spontaneous reduction in the IMA in HV. First metatarsal head translation through an osteotomy should not be considered as the only procedure to correct IMAs in distal osteotomies.

Rhinoplasty for post-traumatic deviation of the nose with non-incisional external perforated osteotomy

Osteotomy is often necessary for the repair of post-traumatic nasal bone deformities. Typically, tools such as chisels are used for osteotomies; however, we performed osteotomies using Kirschner wires without making a skin incision. Between April 2011 and July 2022, we performed rhinoplasty with external perforated osteotomy using Kirschner wires in 13 patients with post-traumatic nasal bone deformities (9 males and 4 females; mean age, 34 years, range 12-51 years), all of whom exhibited improvement, with only one case showing mild residual cosmetic deformity. None of the patients requested further revision, and all were satisfied with their functional results. The non-incisional external perforated technique is a reasonable method that allows for bone osteotomies along the fracture line and is well-controlled, predictable, and reproducible.

Corrective Open-wedge Valgus Proximal Humerus Lengthening Osteotomy. Technique and Case Series.

Symptomatic varus malunion after proximal humeral fractures is associated with weakness and painful limitation of shoulder range of motion. When there is conformity of the articular surface and no avascular necrosis, a head-preserving procedure is best indicated. Arthroscopic arthrolysis, subacromial decompression, and tuberoplasty have been described for the treatment of mild deformity. In cases with more severe deformity, corrective extracapsular lateral closing wedge valgus osteotomy has been reported as a reliable treatment option, in terms of both pain relief and improved function. While this procedure adequately restores rotator cuff tensioning, it is associated with a shortening of the lever arm to the deltoid muscle, secondary to a loss of humeral length. We describe our technique and results with a vascular-sparing, medial open-wedge osteotomy, using a structural allograft and lateral locking plate. In our opinion, this procedure is safe and effective, with the potential to improve functional outcomes in young and active patients.

Measurement of distances and locations of thoracic and lumbar vertebral bodies from CT scans in cases of spinal deformation

BackgroundSpinal deformations, except for acute injuries, are among the most frequent reasons for visiting an orthopaedic specialist and musculoskeletal treatment in adults and adolescents. Data on the morphology and anatomical structures of the spine are therefore of interest to orthopaedics, physicians, and medical scientists alike, in the broad field from diagnosis to therapy and in research.MethodsAlong the course of developing supplementary methods that do not require the use of ionizing radiation in the assessment of scoliosis, twenty CT scans from females and males with various severity of spinal deformations and body shape have been analysed with respect to the transverse distances between the vertebral body and the spinous process end tip and the skin, respectively, at thoracic and lumbar vertebral levels. Further, the locations of the vertebral bodies have been analysed in relation to the patient’s individual body shape and shown together with those from other patients by normalization to the area encompassed by the transverse body contour.ResultsWhile the transverse distance from the vertebral body to the skin varies between patients, the distances from the vertebral body to the spinous processes end tips tend to be rather similar across different patients of the same gender. Tables list the arithmetic mean distances for all thoracic and lumbar vertebral levels and for different regions upon grouping into mild, medium, and strong spinal deformation and according to the range of spinal deformation.ConclusionsThe distances, the clustering of the locations of the vertebral bodies as a function of the vertebral level, and the trends therein could in the future be used in context with biomechanical modeling of a patient’s individual spinal deformation in scoliosis assessment using 3D body scanner images during follow-up examinations.

TREATMENT OF PAEDIATRIC ARTHROGRYPOTIC CLUBFOOT: 20 YEARS OF CLINICAL EXPERIENCE

BackgroundTreatment of arthrogrypotic clubfoot (AC) presents a challenging problem. Over time many different methods have been proposed, with variable rates of success, recurrence and other complications. In this study we describe our 20-year experience in treatment of AC.Materials and methodsBetween 1996 and 2016, 165 AC in 90 children (51 males and 39 females) were treated in our department. Their mean age was 7.6 years (3 months-16 years). Ponseti casting and Achilles tendon release (PCATR) was performed on 38 children (68 feet) and soft tissue release and casting (STRC) on 35 children (67 feet). The remaining 17 children (30 feet) underwent wide soft tissue release and correction using the Ilizarov method (STRIL). The results of each subgroup were graded according to clinical (pain, foot appearance, residual deformities, walking and standing status and shoe modifications) and radiological (anteroposterior and lateral talocalcanear angles, the angle between longitudinal axes of talus and the first metatarsal and the position of talus in the lateral view) criteria.ResultsThe average follow up was 6.4 (2–10) years. Results were excellent (plantigrade, painless, properly loaded feet, without deformities, adapted to common shoes) in 56 PCATR group feet, 59 STRC group feet and 23 STRIL group feet. Good results (required orthopaedic shoes) were obtained in 10 PCATR group feet, 6 STRC group feet and 7 STRIL group feet. Fair results (residual temporary pain and/or mild deformity) presented 2 PCATR group feet and 1 STRC group foot, while bad results (reoccurrence of clubfoot) were found in 1 STRC group foot.ConclusionsOn the basis of our 20-year clinical experience we believe that pediatric AC can be successfully treated with PCATR in the age of less than 1 year old (y.o), with STRC between 1–5 y.o. and with STRIL in children over the age of 5 y.o.

Treatment of Medial Patellar Instability With Bipolar Patellofemoral Cartilage Lesions: Staged De-rotational Distal Femoral Osteotomy Followed by Bipolar Osteochondral Allograft Transplantation and Tibial-Tubercle Osteotomy

Background: Patellar instability with symptomatic cartilage lesions in young patients is a challenging problem to treat. The use of osteotomies to correct malalignment and fresh osteochondral allograft transplantation (OCA) to address cartilage lesions and patellofemoral dysplasia is a viable treatment option for carefully selected patients. Indications: The patient is a 22-year-old woman with medial patellar instability caused by iatrogenic distal femoral external rotation and uncontained grade IV patellofemoral lesions. The patient was indicated for OCA because the lesions were too large for an osteochondral autograft transfer system (OATS) and were uncontained and not amenable to autologous chondrocyte implantation. Bipolar OCA also addresses the patient’s patellofemoral dysplasia by restoring a more morphologically normal patellofemoral joint. The external rotation and mild varus deformity are corrected with a biplanar distal femoral osteotomy. Correction of malalignment is necessary prior to OCA transplantation to avoid abnormal graft loading and thereby decrease the risk of graft failure. Technique Description: (1) Diagnostic arthroscopy and fluoroscopic examination under anesthesia. (2) Lateral closing wedge de-rotational distal femoral osteotomy. (3) Bipolar OCA with tibial tubercle osteotomy and removal of hardware. Results: In this case, the patient had significant improvement in her symptoms and had full knee range of motion with a normal gait at 3 months after surgery. Depending on a patient’s preoperative function and the specific pathology, full recovery can take considerably longer. A successful outcome is considered return to activities of daily living without significant pain. Return to higher level athletic activities is significantly more unpredictable. Graft survival of bipolar patellofemoral OCA is variable, and the literature is limited by the small number of procedures performed, but published series range from 60% to 85% at 5 years. Discussion/Conclusion: A successful outcome in these unique, complex cases depends on good patient selection, preoperative planning, and surgical execution. Patellar instability can be reliably treated when the predisposing anatomical factors are appropriately corrected. Bipolar OCA can provide significant improvement in pain and function, but continues to have the highest rate of graft failure compared with other sites within the knee, and should be considered a salvage operation for patients with significant limitations in activities of daily living.

Question mark ear deformity: a case study and surgical technique

Clefts of the ear are rare and typically develop within the earlobe. They were first described by Vincent et al. in association with urogenital anomalies. Subsequently, Cosman reported them in 1970, referring to the condition as “question mark ear,” which led to its naming. This deformity is infrequently reported and is not well-documented in the literature. In this paper, we present the first reported case in the Omani population of bilateral Cosman ear, associated with a mild cranial deformity. We also discuss the social impact of this condition and introduce our corrective technique for moderate forms of deformity.

NOVEL APPROACH: PERCUTANEOUS INJECTION OF BONE-SUBSTITUTE (CERAMENT-GTM) TO AID BONY HEALING IN STIFF NONUNITED COMPLEX OPEN TIBIAL FRACTURES

IntroductionTreatment of non-union in open tibial fractures Gustilo-Anderson(GA)-3A/3B fractures remains a challenging problem. Most of these can be dealt using treatment methods that requires excision of the non-union followed by bone grafting, masquelet technique, or acute shortening. Circular fixators with closed distraction or bone transport also remains a useful option. However, sometimes due to patient specific factors these cannot be used. Recently antibiotic loaded bone substitutes have been increasingly used for repairing infected non-unions. They provide local antibiotic delivery, fill dead space, and act as a bone conductive implant, which is resorted at the end of a few months. We aimed to assess the outcome of percutaneous injection of bone substitute while treating non-union of complex open tibial fractures.Materials &amp; MethodsThree cases of clinical and radiological stiff tibial non-union requiring further intervention were identified from our major trauma open fracture database. Two GA-3B cases, treated with a circular frame developed fracture-related-infection(FRI) manifesting as local cellulitis, loosened infected wires/pins with raised blood-markers, and one case of GA-3A treated with an intramedullary nail. At the time of removal of metalwork/frame, informed consent was obtained and Cerament-GTM(bone-substitute with gentamicin) was percutaneously injected through a small cortical window using a bone biopsy(Jamshedi needle). All patients were allowed to weight bear as tolerated in a well-fitting air-cast boot and using crutches. They were followed up at 6 weekly intervals with clinical assessment of their symptoms and radiographs. Fracture union was assessed using serial radiographs with healing defined as filling of fracture gap, bridging callus and clinical assessment including return to full painless weight bearing.ResultsFollow-up at 6 months showed all fractures had healed with no defect or gaps with evidence of new trabecular bone and significant resorption of Cerament-GTM at final follow-up. There was no evidence of residual infection with restoration of normal limb function. Fractures with no internal fixation showed a mild deformity that had developed during the course of the healing, presumed due to mild collapse in the absence of fixation. These were less than 10 degrees in sagittal and coronal planes and were clinically felt to be insignificant by the patients.ConclusionsCerament-G's unique combination of high dose antibiotics and hydroxy apatite matrix provided by calcium sulphate might help provide an osteoconductive environment to allow these stiff non-unions to heal. The matrix appears to provide a scaffold-like structure that allows new bone in-growth with local release of antibiotics helping reduce deep-seated infections. The final deformation at fracture site underlines the need for fixation- and it is very unlikely that this technique will work in mobile nonunions. Whilst similar fractures may heal without the use of bone substitute injections, the speed of healing in presence of significant fracture gap suggests the use of these bone substitutes did help in our cases. Further studies with a larger cohort, including RCTs, to evaluate the effectiveness of this technique compared to other methods are needed.

Age-dependent Sagittal Plane Remodeling of Pediatric Supracondylar Fractures.

Current treatment guidelines for pediatric supracondylar fractures have not fully accounted for age-related variations in the remodeling potential. This study aimed to explore age-dependent sagittal plane remodeling in supracondylar fractures by assessing cases with residual deformities after treatment. This study included 62 patients under 16 years of age treated for supracondylar fractures at our institution from 2002 to 2022. The distance between the posterior and anterior aspects of the capitellar ossific nucleus (CON) was defined as the CON size, while the distance from the anterior humeral line to the posterior aspect of CON was termed DAP-CON. The value obtained by subtracting the DAP-CON on the unfractured side from the DAP-CON on the fractured side was divided by the CON size and multiplied by 100 and termed the displacement of CON (d-CON). The absolute value of the difference between d-CON after intervention and d-CON at the last follow-up was denoted as sagittal plane remodeling. For this patient cohort, the mean age was 5.5 years (range, 1.4 to 14.6 years), and the mean follow-up period was 30.4 months (range, 12.0 to 137.1 months). Sagittal plane remodeling was more pronounced in children younger than 5 years (group I) compared with those older (group II) ( P <0.001). In multiple regression analysis, only age at the time of injury was found to be a significant variable ( P <0.001). The receiver operating characteristic curve analysis identified 4.2 years as the cutoff age for predicting >33% sagittal plane remodeling, with an area under the curve of 0.975. Children below the age of 5 years exhibit sagittal plane remodeling, with a cutoff age identified at 4.2 years for achieving >33% of d-CON. This indicates that mild deformities (16.5%<d-CON ≤ 33%) can be expected to be fully remodeled before the age of 4.2 years, suggesting that the patient's age needs to be considered in the treatment guidelines.
