Meaning(s) of transition(s) from military to civilian life at the intersection with mental health: implications for clinical settings.

The experiences of military personnel moving into civilian life can be varied for the individual, families and communities. This paper aims to shed light on the various meanings of the multiple and "nested" transitions of military personnel to civilian life in the context of attending a mental health service in the UK. This was achieved through secondary analysis of semi-structured interviews with veterans who were engaging with a mental health service in the UK and a further interview with the mental health service lead. A thematic analysis was employed based on a descriptive phenomenological approach. Results indicate that an appropriate support infrastructure needs to be put in place for veterans prior to, during and after the transition to civilian life. The support appropriateness includes themes specific to connectedness to others, support service accessibility, mental health professionals' military culture awareness and mental health stigma. Although the findings suggest that community services need an awareness of veterans' specific needs, many of the themes are similar to those of the general population. Therefore, the need for an integrated healthcare system is essential in the transition of military service personnel to civilian life. Drawing on international evidence as well as the current findings, implications for policy and practice are highlighted throughout.

Predicting Deformity Correction of Growth Modulation in Late-onset Tibia Vara.

BACKGROUND: Growth modulation in late-onset tibia vara (LOTV) has been reported to yield variable results. We hypothesized that parameters of deformity severity, skeletal maturity, and body weight could predict the odds of a successful outcome. METHODS: A retrospective review of tension band growth modulation for LOTV (onset ≥8 y) was performed at 7 centers. Tibial/overall limb deformity and hip/knee physeal maturity were assessed on preoperative anteroposterior standing lower-extremity digital radiographs. Tibial deformity change with first-time lateral tibial tension band plating (first LTTBP) was assessed by medial proximal tibia angle (MPTA). Effects of a growth modulation series (GMS) on overall limb alignment were assessed by mechanical tibiofemoral angle (mTFA) and included changes from implant removal, revision, reimplantation, subsequent growth, and femoral procedures during the study period. The successful outcome was defined as radiographic resolution of varus deformity or valgus overcorrection. Patient demographics, characteristics, maturity, deformity, and implant selections were assessed as outcome predictors using multiple logistic regression. RESULTS: Fifty-four patients (76 limbs) had 84 LTTBP procedures and 29 femoral tension band procedures. For each 1-degree decrease in preoperative MPTA or 1-degree increase in preoperative mTFA the odds of their successful correction decreased by 26% in the first LTTBP and 6% by GMS, respectively, controlling for maturity. The change in odds of success for GMS assessed by mTFA was similar when controlling for weight. Closure of a proximal femoral physis decreased the odds of success for postoperative-MPTA by 91% with first LTTBP and for final-mTFA by 90% with GMS, controlling for preoperative deformity. Preoperative weight ≥100 kg decreased the odds of success for final-mTFA with GMS by 82%, controlling for preoperative mTFA. Age, sex, race/ethnicity, type of implant, and knee center peak value adjusted age (a method for bone age) were not predictive of outcome. CONCLUSIONS: Resolution of varus alignment in LOTV using first LTTBP and GMS, as quantified by MPTA and mTFA, respectively, is negatively impacted by deformity magnitude, hip physeal closure, and/or body weight ≥100 kg. The presented table, utilizing these variables, is helpful in the prediction of the outcome of the first LTTBP and GMS. Even if complete correction is not predicted, growth modulation may still be appropriate to reduce deformity in high-risk patients. LEVEL OF EVIDENCE: Level III.

Predicting Success of Deformity Correction With Tension Band Plating in Early-Onset Tibia Vara.

BACKGROUND: Angular deformity correction with tension band plating has not been as successful in early-onset tibia vara (EOTV) as it has been in other conditions. Our hypothesis is that perioperative factors can predict the success of lateral tibial tension band plating (LTTBP) in patients with EOTV. METHODS: A retrospective review was performed at 7 centers evaluating radiographic outcomes of LTTBP in patients with EOTV (onset <7 y of age). Single-event tibial LTTBP outcome was assessed through medial proximal tibial angle (MPTA). The final limb alignment following comprehensive limb growth modulation (CLGM), which could include multiple procedures, was assessed by mechanical axis zone (MAZone), mechanical tibio-femoral angle (mTFA), and mechanical axis deviation (MAD). Preoperative age, weight, deformity severity, medial physeal slope, and Langenskiöld classification +/- modification were investigated as predictors of outcome. Success was defined as the correction or overcorrection to normal age-adjusted alignment. The minimum follow-up was 2 years except when deformity correction, skeletal maturity, or additional surgery occurred. RESULTS: Fifty-two patients with 80 limbs underwent 115 tibial LTTBP procedures at a mean age of 5.3 y, including 78 primary, 21 implant revisions, and 15 reimplantations for recurrence. Tibial LTTBP resulted in a mean change of +8.6 o in MPTA and corrected 53% of tibias. CLGM resulted in MAD correction for 54% of limbs.Univariate analysis showed that success was best predicted by preoperative age, weight, MPTA, and MAD. Multivariate analysis identified that preoperative-MPTA/MAD and preoperative-weight<70 kg were predictive of MPTA and MAD correction, respectively. The probability of success tables are presented for reference. CONCLUSION: Successful correction of MPTA to age-adjusted norms following a single-event LTTBP occurred in 53% of tibias and was best predicted by preoperative-MPTA and preoperative body weight <70 kg. Comprehensive growth modulation corrected limbs in 54%. The probability of correction to age-adjusted MAD is best estimated by preoperative-MAZone 1 or 2 (MAD ≤40 mm). Limbs with preoperative-MAD>80 mm improved, but ultimately all failed to correct completely with CLGM. Osteotomy may need to be considered with these severe deformities. While modified Langenskiöld classification and medial physeal slope have been shown to predict the outcome of osteotomy, they were not predictive for LTTBP. Change in MPTA was common after physeal untethering. LEVEL OF EVIDENCE: Level-III.

Femoral Deformity in Tibia Vara and Its Response to Growth Modulation.

BACKGROUND: While tibia vara is a disorder of the proximal tibial physis, femoral deformity frequently contributes to the overall limb malalignment. Our purpose was to determine how femoral varus deformity in tibia vara responds to growth modulation, with/without lateral tension band plating (LTBP) to the femur. METHODS: One-hundred twenty-seven limbs undergoing LTBP for tibia vara were reviewed. All had tibial LTBP and 35 limbs also had femoral LTBP for varus. Radiographs were measured for correction of the mechanical lateral distal femoral angle (mLDFA) and mechanical axis deviation (MAD). Preoperative-femoral varus was defined with an age-adjusted guide: mLDFA >95 degrees for 2 to below 4 years and mLDFA >90 degrees for 4 to 18 years. The 35 limbs having femoral LTBP were compared with 50 limbs with femoral varus and no femoral LTBP. In addition, 42 limbs that did not have preoperative-femoral varus were followed. Patients with early-onset (below 7 y) tibia vara were compared with those with late-onset (≥8 y). Outcome success was based on published age-adjusted mLDFA and MAD norms. RESULTS: Following femoral LTBP, the mean mLDFA decreased from 98.0 to 87.1 degrees. All femurs had some improvement, with 28/35 femurs (80%) achieving complete correction. One limb, with late follow-up, overcorrected, requiring reverse (medial) femoral tension band plating.For the 50 limbs with femoral varus and only tibial LTBP, 16/22 limbs (73%) with early-onset and 11/28 limbs (39%) with late-onset completely corrected their femoral deformities. If the limb had preoperative-femoral varus, femoral LTBP statistically correlated with successful mLDFA correction and improvement of MAD, only in the late-onset group.Forty-two limbs, without preoperative-femoral varus, had no change in their mean mLDFA of 87 degrees. However, 4 femurs (10%) ended with posttreatment varus. CONCLUSIONS: Femoral LTBP is effective in correcting femoral varus deformity in the tibia vara. For femoral varus associated with late-onset tibia vara, femoral LTBP should be considered. Those that had femoral LTBP had statistically more successful femoral and overall limb varus correction. However, in early-onset tibia vara, with associated femoral varus, observation is warranted because 73% of femurs are corrected without femoral intervention. This study was underpowered to show additional improvement with femoral LTBP in the early-onset group. Even limbs with normal femoral alignment, should be observed closely for the development of femoral varus, during tibial LTBP treatment for tibia vara. LEVEL OF EVIDENCE: Level III.

Introduction of Balint Groups as a Reflective Practice Method.

Cynicism and burnout are well-described among new medical school graduates. At the new medical school in Washington state, the trend toward placing importance on wellness and creating a culture of healing was present from the outset. To encourage reflective practice, Balint groups were introduced as a method to teach students to think deeply about patient relationships and to address particular curricular objectives, including to demonstrate empathy for healthcare trainees and for patients, and to practice active listening skills in the context of the student Balint groups. The approach presented here will focus on the introduction of Balint groups into the pre-clerkship curriculum as a longitudinal tool to prepare students to use the method with more facility in their clerkships. The presentation at the 2022 American Balint Society Annual Meeting highlighted the introduction of Balint groups to the clinician faculty using the Intensive on the Road format, the introduction of Balint groups to pre-clerkship medical students, and the use of Balint groups in the pre-clerkship curriculum. The operational aspects, including faculty recruitment and retention, as well as student groupings and scheduling, were addressed in the context of the overall theme of monitoring student progress toward open communication about their challenging patient relationships. Programmatic evaluation and current trends were emphasized, along with the anticipated evolution and future directions of the program at our community-based medical school.

Guided Growth for Varus Deformity Following Early Tibial Osteotomy in Infantile Tibia Vara-A Multi-Center Study.

BACKGROUND: Despite early osteotomy, many patients with infantile tibia vara (ITV) have persistent or recurrent varus deformity and disordered growth at the medial proximal tibial physis. Our hypothesis was that lateral tibial tension band plating (LTTBP) could guide correction. METHODS: A retrospective review at 6 centers of 15 patients (16 extremities) was performed of LTTBP for varus deformity following early osteotomy in ITV, diagnosed≤4years of age. Correction of deformity parameters on digital standing anteroposterior lower extremity radiographs determined outcome. RESULTS: Twenty-two LTTBP procedures were performed at mean age of 7.5 years, including 4 revisions for implant failure and 2 reimplantations for recurrence. Single event LLTBP, improved the medial proximal tibial angle with a mean change of 13.4 degrees (0.39 degrees/month). Eleven limbs had preoperative mechanical lateral distal femoral angle (mLDFA)>90 degrees. While n degree femoral procedures were performed, at study end, 11 femurs had mechanical lateral distal femoral angle≤90°. Pretreatment, 13 extremities had mechanical axis zone (MAZone) III varus (81%) and 3 had MAZone II varus (19%). LTTBP's were able to initially correct 13 limbs to MAZone I or valgus but 4 limbs rebounded to MAZone II varus after implant removal. Final limb alignment, after all surgeries and rebound, included 9 in MAZone I, 5 in MAZone II varus and 2 in MAZone III varus. Average follow-up was 3.0 years at mean 10.7 years of age. Fifteen procedures resulted in improvement in MAZone and 7 had no change. On average, those that improved were younger (7.3 vs. 8.0 y), weighed less (45.5 kg with body mass index 26.5 kg/m 2 vs. 67.8 kg and body mass index 35.7 kg/m 2 ), had lower mechanical axis deviation (37.1 mm vs. 43.9 mm), lower medial physeal slope (61.7 vs. 68.7 degrees) and had a higher percentage of open triradiate phases (87 vs. 57%). CONCLUSIONS: LTTBP for residual varus, after initial osteotomy in ITV, resulted in 81% of limbs initially achieving MAZone I or valgus with implant failure revisions and femoral remodeling. Rebound after implant removal reduced the corrected rate to 56%. Ninety-four percent avoided osteotomy during the study period. LEVEL OF EVIDENCE: IV.

The Costs of Interfacility Transfers for Nonurgent Pediatric Supracondylar Fractures.

BACKGROUND: Unnecessary transfers of nonemergent pediatric musculoskeletal injuries to regional trauma centers can be costly. The severity of fracture displacement in supracondylar humerus fractures dictates the risk of complications, the urgency of transfer and the need for surgical treatment. The purpose of this study is to examine the transfer patterns of Gartland type II pediatric supracondylar humerus fractures to identify strategies for improving patient care, improving health care system efficiency, and reducing costs. We hypothesize that there will be a high rate of unnecessary, emergent transfers resulting in increased cost. METHODS: We retrospectively identified all pediatric patients that underwent treatment for a supracondylar humerus fracture between 2013 and 2018. Patient demographics, injury characteristics, chronological data, and surgical data were collected and analyzed from ambulance run sheets, transferring hospital records, and electronic medical records. Transfer distances were estimated using Google-Maps, while transfer costs were estimated using Internal Revenue Service (IRS) standard mileage rates and the American Ambulance Association Medicare Rate Calculator. A student t test was used to evaluate different treatment groups. RESULTS: Sixty-two patients had available and complete transfer data, of which 44 (71%) patients were safely transferred via private vehicle an average distance of 51.8 miles, and 18 (29%) patients were transferred via ambulance on an average distance of 55.6 miles ( P =0.76). The average transfer time was 4.1 hours by private vehicle, compared with 3.9 hours by ambulance ( P =0.56). The average estimated cost of transportation was $28.23 by private vehicle, compared with $647.83 by ambulance ( P =0.0001). On average, it took 16.1 hours after injury to undergo surgery and 25.7 hours to be discharged from the hospital, without a significant difference in either of these times between groups. There were no preoperative or postoperative neurovascular deficits. CONCLUSION: Patients with isolated Gartland type II supracondylar humerus fractures that are transferred emergently via ambulance are subjected to a significantly greater financial burden with no demonstrable improvement in the quality of their care, since prior research has shown these injuries can safely be treated on an outpatient basis. Potential options to help limit costs could include greater provider education, telemedicine and improved coordination of care. LEVEL OF EVIDENCE: Level III (retrospective comparative study).

Evaluation of a Skills Enhancement Training Intervention With Remote Coaching for Young Adults Providing Peer Support.

This column reports on a study that investigated a skills enhancement and role clarification training intervention for young adult peer support specialists (YPSSs). Young adults who had received intensive mental health services­including young adults who had experience as YPSSs­were partners in developing the intervention and in completing all aspects of the study. Study participants were YPSSs who were already providing one-on-one, person-centered planning in community settings before the study. The results, based on YPSSs' self-reports and rated video recordings of YPSSs' practice, showed postintervention gains in participants' skills and confidence in providing person-centered planning to the young people they worked with as well as reduced job-related anxiety and high training satisfaction.

"Not all groups come together, but this one just clicks": Ten Tips for Sustaining an Engagement Panel.

In 2017, ten veteran patients with the shared experience of living with chronic pain united to form a Veteran Engagement Panel (VEP) to support the Patient-Centered Outcomes Research Institute® (PCORI®)funded Veterans Pain Care Organizational Improvement Comparative Effectiveness (VOICE) Study. The study, conducted at ten Veterans Affairs (VA) sites, compares two team-based approaches to improve pain management and reduce potential harms of opioid therapy. The panel shares ten best practices for sustaining a successful engagement partnership.

Aboveground competition influences density-dependent effects of cordgrass on sediment biogeochemistry.

Interspecific interactions between plants influence plant phenotype, distribution, abundance, and community structure. Each of these can, in turn, impact sediment biogeochemistry. Although the population and community level impacts of these interactions have been extensively studied, less is known about their effect on sediment biogeochemistry. This is surprising given that many plants are categorized as foundation species that exert strong control on community structure. In southern California salt marshes, we used clipping experiments to manipulate aboveground neighbor presence to study interactions between two dominant plants, Pacific cordgrass (Spartina foliosa) and perennial pickleweed (Sarcocornia pacifica). We also measured how changes in cordgrass stem density influenced sediment biogeochemistry. Pickleweed suppressed cordgrass stem density but had no effect on aboveground biomass. For every cordgrass stem lost per square meter, porewater ammonium increased 0.3-1.0 µM. Thus, aboveground competition with pickleweed weakened the effects of cordgrass on sediment biogeochemistry. Predictions about plant-soil feedbacks, especially under future climate scenarios, will be improved when plant-plant interactions are considered, particularly those containing dominant and foundation species.

Guided Growth Procedures: Broken Tension Band Implants in Patients With Blount Disease.

BACKGROUND: Tension band plate and screw implants (TBI) are frequently used for temporary hemiepiphyseodeses to manage angular deformity in growing children. The reported implant breakage rate, when TBI is used for deformities in patients with Blount disease, is much higher than when used in other diagnoses. Our hypothesis is that perioperative factors can identify risks for TBI breakage. METHODS: A retrospective case-control study was performed of 246 TBI procedures in 113 patients with Blount disease at 8 tertiary pediatric orthopaedic centers from 2008 to 2018. Patient demographics, age at diagnosis, weight, body mass index (BMI), radiographic deformity severity measures, location, and types of implants were studied. The outcome of implant breakage was compared with these perioperative factors using univariate logistic regression with Bonferroni correction for multiplicity to significance tests. RESULTS: There were 30 broken implants (12%), failing at mean 1.6 years following implantation. Most failures involved the metaphyseal screws. Increased BMI was associated with increased implant breakage. Increased varus deformity was directly associated with greater implant breakage and may be a more important factor in failure for those below 7 years compared with those 8 years or above at diagnosis. There was a 50% breakage rate for TBI with solid 3.5 mm screws in Blount disease with onset 8 years or above of age. No demographic or implant factors were found to be significant. CONCLUSIONS: Breakage of TBI was associated with increased BMI and varus deformity in patients with Blount disease. Larger studies are required to determine the relative contribution and limits of each parameter. Solid 3.5 mm screws should be used with caution in TBI for late-onset Blount disease. LEVEL OF EVIDENCE: Level III.

Assessment of Lateral Rotation Percentage and Rotational Deformity of the Elbow in Type 3 Supracondylar Humerus Fractures: A Biomechanical Study.

BACKGROUND: Supracondylar humerus (SCH) fractures are the most common elbow fractures in children. Historically, displaced (Gartland type 3) SCH fractures have been treated with closed reduction and percutaneous pinning. Fluoroscopic imaging is used intraoperatively in order to assess adequate reduction of the fracture fragments before pinning. On lateral fluoroscopic and radiographic images, a lateral rotation percentage (LRP) can be estimated in order to assess rotational deformity. The purpose of this study was to determine the true rotational deformity of distal humerus fracture fragments in SCH fractures based upon the LRP using a clinically relevant laterally based pinning technique. METHODS: In this study, a sawbones model was used to examine the correlation between calculated LRP and the true degree of rotational deformity with 3 of the most common extension-type SCH fracture types (low transverse, high transverse, and lateral oblique). Because fracture stability was not the focus of this study, a single pin was used to hold the construct and allow for fragment rotation along a fixed axis. In this study, 2 of the authors independently measured rotational deformity and compared this with LRP on fluoroscopic lateral imaging of a sawbones model at 0 to 45 degrees of rotational deformity. RESULTS: The LRP of all 3 patterns demonstrated a near linear increase from 0 to 45 degrees with maximum LRP measured at 45 degrees for each of the 3 patterns. Univariate linear regression demonstrated an increase in LRP for the low transverse pattern of 2.02% for every degree of rotation deformity (R2=0.97), 2.29% for the lateral oblique pattern (R2=0.986), and 1.17% for the high transverse pattern (R2=0.971). Maximum LRP was measured at 45 degrees for all 3 patterns with a mean of 53.5% for the high transverse pattern, 93.5% for the low transverse pattern, and 111.2% for the lateral oblique pattern. A higher LRP was measured with increasing degrees of rotational displacement in the low transverse and lateral oblique patterns for all degrees of rotational deformity compared to the high transverse pattern. CONCLUSION: There is a near linear correlation between the degree of malrotation and the LRP with more superior metaphyseal fracture patterns demonstrating a lower LRP than inferior fracture patterns. CLINICAL RELEVANCE: Using our data one can estimate the degree of malrotation based on the LRP on radiographs in the clinical setting. LEVEL OF EVIDENCE: Not applicable (basic-science article).

Development of a method to produce a valid and reliable foot mask for plantar pressure evaluation in children with clubfoot.

The purposes of this article are to describe common masking inaccuracies, provide a standard methodology for correcting inaccuracies, and report intra/interclinician reliability when novice and experts mask foot pressures for children with clubfoot. Foot pressures from 26 children (ages 2.6-12.9 years) with unilateral clubfoot were utilized. Three raters were used for intra/interclinician reliability: one expert masker with 8 years of experience and two novice maskers. For children with unilateral clubfoot, automated masking was inaccurate in 4% of trials on the unaffected side and 24% of trails on the affected side. Novice and expert maskers report good-excellent reliability (interclass correlation coefficient range 0.61-1.0) when identifying and correcting inaccurate masks. To obtain accurate and reliable foot pressure data, it is recommended to first utilize an automasking technique and apply manual editing. This is the first study to present a standard methodology for foot pressure mask editing, the first to present the incidence of mask inaccuracies and the first to present foot pressure masking reliability in children with clubfoot.

Local and regional variation in effects of burrowing crabs on plant community structure.

Burrowing animals can profoundly influence the structure of surrounding communities, as well as the performance of individual species. Changes in the community structure of burrowing animals or plants together with changing abiotic parameters could shift the influence of burrowers on surrounding habitats. For example, prior studies in salt marshes suggest that fiddler crabs stimulate cordgrass production, but leaf-grazing crabs suppress cordgrass production. Unfortunately, testing this prediction and others are impeded because few studies have examined crab impacts on the plant community and across multiple sites, multiple years, or both. This challenges our ability to predict how burrowing animals will influence plant community structure, and when and where these impacts will occur. We manipulated the densities of the dominant burrowing crabs in plant assemblages dominated by Pacific cordgrass (Spartina foliosa) and perennial pickleweed (Sarcocornia pacifica) at three sites in southern California for three years (2016, 2017, 2018). Crab impacts on plant community structure differed among each of our three sites. In contrast to our predictions, (1) leaf-grazing crabs (Pachygrapsus crassipes) had positive effects on cordgrass cover at one site and no effect on cordgrass production at a nearby site in the same marsh and (2) fiddler crabs (Uca crenulata) did not stimulate cordgrass production at another marsh. Because crabs affected traits of cordgrass, but not pickleweed, in the direction consistent with changes in cordgrass cover, we propose that marsh-specific crab effects on community structure were largely mediated through changes in cordgrass, as opposed to pickleweed. Importantly, crabs facilitated cordgrass during marsh-wide cordgrass loss, suggesting that crabs may mitigate environmental stress for this ecologically important plant. Because cordgrass abundance can be a critical measure of marsh functioning and is often a restoration target, we suggest that managing cordgrass populations would benefit from additional information about crab populations and their impacts among years, and among and within marshes.

The impact of stress on depression, ill health and coping in family members caring for patients with acquired brain injury.

BACKGROUND: This study investigated the impact of stress on levels of depression and ill health as an indication of psychological coping. The research sample consisted of 80 family caregivers (who are members of Headway Gauteng, located in Johannesburg, South Africa) of patients with acquired brain injury. METHODS: A mixed method design of data collection was utilised that included self-report procedures (structured questionnaires and interviews) and post-interview content analyses. In addition, two individually administered measures that have been widely used in clinical practice and research were administered (a stress symptom checklist and the Beck Depression Inventory). RESULTS: The majority of the research participants experienced high levels of stress along with an inordinate physical and mental health impact indicating that they were not able to cope up with the ongoing chronic stress of caregiving. CONCLUSION: Findings provide compelling evidence of the value of psychological screening for elevated stress and poor coping in family members caring for a patient with acquired brain injury in a resource-limited healthcare society. We recommend a collaborative effort between medical and psychological health practitioners in order to ensure a holistic and inclusive approach towards treatment procedures and interventions to improve coping skills in family members caring for a patient with acquired brain injury.

Brace Yourselves: Outcomes of Ponseti Casting and Foot Abduction Orthosis Bracing in Idiopathic Congenital Talipes Equinovarus.

BACKGROUND: Foot abduction orthoses (FAO) are believed to decrease recurrence following treatment of congenital talipes equinovarus (CTEV) as described by Ponseti. The purpose of this project is to examine the outcomes of FAO bracing following treatment by the Ponseti method in a cohort of idiopathic CTEV patients. METHODS: After IRB approval, a cohort of patients aged 3 to 46 days with idiopathic CTEV was identified in a previous prospective study of brace compliance by family report and sensor. Dimeglio score and family demographic information were collected. Initial treatment was by the Ponseti method, with or without Achilles tenotomy. Following correction, patients had three months of full-time FAO bracing during which parents kept a log of compliance. Patients were followed until recurrence (need for further treatment) or age 5. RESULTS: In total, 42 patients with 64 affected feet met the above criteria and were included in the final analysis. Twenty-six feet (40%) went on to develop recurrence requiring further treatment, including casting, bracing, or surgery. Because of poor tolerance of the original FAO, 20 feet were transitioned to an alternative FAO, and 14 of these (70%) went on to recur (P<0.01). The casting duration (P=0.02) had a statistically significant relationship to recurrence. Patients who were casted for 9 weeks or more had a higher rate of recurrence (57.1% vs. 27.8%; P=0.02). Age at treatment start, Dimeglio score, demographic factors, and compliance during full-time bracing, whether by report or sensor, did not show a significant relationship with recurrence. CONCLUSIONS: The study showed a statistically significant relationship between the difficulty of CTEV correction and the risk of recurrent deformity requiring treatment. This relationship could be used to provide prognostic information for patients' families. Caregiver-reported compliance was not significantly related to recurrence. LEVEL OF EVIDENCE: Level III-Prognostic Retrospective Cohort Study.

Upper extremity anomalies in children with femoral and fibular deficiency.

Defects occurring in the femoral-fibular-ulnar developmental field are believed to cause the cluster of anomalies seen with femoral, fibular and ulnar limb deficiencies. Upper limb function must be considered in the management of lower limb deficiencies. The purpose of this study is to determine the frequency and type of upper extremity anomalies found in children with femoral and/or fibular deficiency. A retrospective review of 327 consecutive patients with the diagnosis of femoral and/or fibular deficiency was performed using existing records and radiographs. Characteristics of those with and without upper extremity anomalies were compared. Upper extremity anomalies were identified in 56 patients. They were more common among those with bilateral, compared with unilateral, lower extremity deficiencies (P < 0.0001). Seventy-five upper limbs were involved with 50 ulnar deficiencies, nine congenital transhumeral deficiencies, four congenital shoulder disarticulations, seven cleft hands, two radial head dislocations and one each - radial deficiency, syndactyly and capitate-lunate coalition. Two patients with bilateral upper extremity anomalies had ulnar deficiency on one side and a transverse deficiency on the other. Upper extremity anomalies are found in 17% of children with femoral and/or fibular deficiency, especially with bilateral lower extremity involvement. Ulnar deficiency is the most common type but one-third had other anomalies. The frequent finding of congenital transverse upper extremity deficiencies suggests there may be common embryology.

Idiopathic Genu Valgum and Its Association With Obesity in Children and Adolescents.

BACKGROUND: Obesity as a cause of lower extremity deformity in children has been well established. This deformity is most often seen as tibia vara, however, at our institution we have observed more obese children and adolescents over age 7 years with excessive or progressive idiopathic genu valgum. Our hypothesis is that children with idiopathic genu valgum have high rates of obesity which impact the severity of their disease. METHODS: Retrospective review of existing data was performed on 66 consecutive children/112 limbs over age 7 years with idiopathic genu valgum, seen from 2010 to 2013. Children with known metabolic or skeletal disease were excluded. Genu valgum was defined as mechanical axis in zone II or III and mechanical tibiofemoral angle ≥4 degrees on standing anteroposterior radiograph of the lower extremities. Body mass index (BMI) was calculated and classified by Center for Disease Control percentiles. Skeletal maturation was rated by closure of pelvic and peri-genu physes. Severity of genu valgum was also assessed by femoral and tibial mechanical axes and the mechanical axis deviation. RESULTS: Mean patient age was 12.2±2.2 years. 47% of patients had BMI≥30 and 71% were categorized as obese (>95th percentile). No sex differences were identified. Skeletal maturation explained 25% of the variance in the mechanical axis deviation and 22% of the mechanical tibiofemoral angle. BMI predicted 9.8% of the tibial valgus. Because of its skewed distribution, BMI percentile was a less useful parameter for assessment. CONCLUSIONS: The 71% obesity rate found in our children with idiopathic genu valgum is significantly higher than the normal population. Higher BMI is associated with more tibial valgum but skeletal maturation was the main predictor of overall valgus severity. This suggests that obesity may play a role in the etiology of idiopathic genu valgum which progresses with skeletal maturation, thereby increasing the risk of osteoarthritis in adulthood.

Hamstring lengthening in females with cerebral palsy have greater effect than in males.

Children with spastic diplegia cerebral palsy often demonstrate crouched gait patterns, and typically undergo hamstring lengthenings. The objective of this retrospective study was to determine if the surgical response to medial and lateral hamstring lengthenings is different between males and females. Preoperative and postoperative kinematic data of 109 (71 males and 38 females) patients with cerebral palsy were evaluated. Females demonstrated larger decreases in popliteal angle, larger decreases in mid-stance knee flexion, and higher incidences of knee hyperextension postoperatively. Results indicate that females have larger responses to hamstring lengthenings than males.
