Emergency department diagnosis of pediatric hip effusion and guided arthrocentesis using point-of-care ultrasound

Children with complaints of hip pain, a painful limp, or refusal to weight bear commonly present to the Emergency Department (ED). The ability to use point-of-care ultrasound in the ED to diagnose a hip joint effusion and to guide arthrocentesis can be helpful to facilitate diagnosis and management of these children. The capsular-synovial thickness of the hip is measured from the anterior bony cortical surface to the posterior surface of the iliopsoas muscle at the concavity of the femoral neck. A capsular-synovial thickness > 5 mm, or > 2 mm difference compared to the asymptomatic contralateral hip are the described sonographic criteria for hip joint effusion in children. We report on the use of point-of-care ultrasound to diagnose hip effusion and to guide arthrocentesis in a series of pediatric patients presenting with hip pain to the ED.     

Novel joint cupping clinical maneuver for ultrasonographic detection of knee joint effusions

IntroductionKnee effusions occur due to traumatic and atraumatic causes. Clinical diagnosis currently relies on several provocative techniques to demonstrate knee joint effusions. Portable bedside ultrasonography (US) is becoming an adjunct to diagnosis of effusions. We hypothesized that a US approach with a clinical joint cupping maneuver increases sensitivity in identifying effusions as compared to US alone.MethodsUsing unembalmed cadaver knees, we injected fluid to create effusions up to 10 mL. Each effusion volume was measured in a lateral transverse location with respect to the patella. For each effusion we applied a joint cupping maneuver from an inferior approach, and re-measured the effusion.ResultsWith increased volume of saline infusion, the mean depth of effusion on ultrasound imaging increased as well. Using a 2-mm cutoff, we visualized an effusion without the joint cupping maneuver at 2.5 mL and with the joint cupping technique at 1 mL. Mean effusion diameter increased on average 0.26 cm for the joint cupping maneuver as compared to without the maneuver. The effusion depth was statistically different at 2.5 and 7.5 mL (P < .05).ConclusionsUtilizing a joint cupping technique in combination with US is a valuable tool in assessing knee effusions, especially those of subclinical levels. Effusion measurements are complicated by uneven distribution of effusion fluid. A clinical joint cupping maneuver concentrates the fluid in one recess of the joint, increasing the likelihood of fluid detection using US.

正常小儿髋关节发育的磁共振成像定量分析

目的 应用磁共振T2W快速梯度回波(FFE)序列进行多参数定量测量,观察正常小儿髋关节发育过程的变化规律。方法 对163名6个月~12岁正常发育小儿髋关节进行MR扫描,测量反映股骨头覆盖率的指标,包括髋臼总覆盖角(TCA)、骨性髋臼覆盖角(ACA)、盂唇覆盖角(LCA),并测量反映髋臼窝宽度、深度和股骨头直径的指标,包括髋臼窝宽度(AW)、髋臼窝深度(AD)和股骨头直径(DFH),并分析以上指标与年龄的相关性。结果 ACA、LCA、AW、AD、DFH均与年龄呈明显相关。TCA在1岁以内与年龄有相关性,1岁以后与年龄无明显相关性。TCA与ACA及LCA均呈明显正相关,ACA与LCA呈明显负相关。结论 正常髋关节的发育是髋臼软骨增加、骨化比例增多、髋臼窝逐渐增大与加深、股骨头逐渐增大的过程。发育早期髋臼软骨及盂唇在维持髋关节承重及保持关节稳定性方面起重要作用。随年龄增大,骨性结构逐渐替代软骨结构的作用,髋臼与股骨头同步发育,髋关节结构始终保持相对稳定。     

Effect of transtrochanteric rotational osteotomy on impingement and contact state of a femoral implant in conversion total hip arthroplasty — Retrospective simulation study

BackgroundThe transtrochanteric rotational osteotomy is a common osteotomy for osteonecrosis of the femoral head, although the results of conversion total hip arthroplasty after the osteotomy are controversial. We evaluated how deformities in the proximal femur after the osteotomy affect hip impingement and the contact state of the stem in total hip arthroplasty.MethodsWe retrospectively reviewed 35 hips (24 men) that had undergone the transtrochanteric rotational osteotomy for osteonecrosis of the femoral head (TRO-group) and compared them with 31 contralateral, unoperated hips (Primary group). The distance between the anterior and posterior greater trochanter at the cutting point of the femur, defined as the greater trochanter width and the contact area of the femoral implant surface with cortical bone were measured by CT-based three-dimensional templating software. We also calculated the hip range of motion in conversion total hip arthroplasty and analyzed the correlations between the greater trochanter width and the range of motion.FindingsThe number of bony-impingement cases was significantly greater, and the range of motion in flexion, internal rotation and external rotation was significantly less in TRO-group. There was a significant negative correlation between the greater trochanter width and range of motion of internal rotation. There were no significant differences between two groups in percentages of femoral-implant contact area.InterpretationsThe femoral implant fixation appears to be satisfactorily fixed in all zones in conversion total hip arthroplasty. However, the greater attention should be paid to minimizing bony impingement, especially on the anterior side, in conversion total hip arthroplasty.     

Hip Labral Reconstruction: Techniques and Outcomes

Purpose of ReviewWith increased understanding of the biomechanical function of the acetabular labrum, more attention has been directed towards surgical techniques that preserve or restore normal joint anatomy. While labral repair has been shown to produce superior outcomes to labral debridement, repair is not always possible in the setting of severe labral intrasubstance tearing or deficiency. These patients were previously left without suitable arthroscopic treatment options.Recent FindingsLabral reconstruction is an emerging procedure that has been shown to offer promising outcomes for traditionally difficult-to-treat hip pathology. Short- and mid-term follow-up studies have consistently demonstrated significant improvement in patient-reported outcomes, function, and patient satisfaction postoperatively, often despite less favorable preoperative characteristics.SummaryLabral reconstruction is a viable arthroscopic treatment option that has been shown to reliably produce clinically meaningful results in patients with severe labral pathology that is not amenable to repair/refixation or augmentation.     

Association between severity of hip chondrolabral injuries,dynamic hip muscle strength and quality of life: A cross-sectional study in patients with femoroacetabular impingement syndrome scheduled for hip arthroscopy

BackgroundWe assessed the association between: the severity of hip chondral or labral pathology with dynamic hip muscle strength or quality of life in patients with femoroacetabular impingement syndrome scheduled for hip arthroscopy. We also assessed the association between dynamic hip muscle strength with quality of life.MethodsEighty-three participants with femoroacetabular impingement syndrome scheduled for hip arthroscopy were included. We measured dynamic hip abduction and adduction muscle strength with an isokinetic dynamometer (Nm/kg), and quality of life with the iHoT-33 questionnaire. The severity of hip chondrolabral pathologies was scored using the modified Beck classification. Linear regression analyses were conducted to assess the association between severity of hip chondral or labral pathology with dynamic hip muscle strength and quality of life.FindingsThe regression analyses showed no association between the (i) severity of hip chondral (adjusted r²: 0.14) or labral (adjusted r²: 0.08) pathology and quality of life (P > 0.05), (ii) between the severity of hip chondral or labral pathology and dynamic hip abduction and adduction muscle strength (P > 0.05). Significant correlation was observed for quality of life and hip abduction (adjusted r²:0.29; P < 0.001) or adduction (adjusted r²: 0.32; P < 0.001) muscle strength.InterpretationThe severity of hip chondral or labral pathologies were not associated with quality of life or dynamic hip muscle strength in participants with femoroacetabular impingement syndrome. Greater dynamic hip abduction and adduction muscle strength were associated with better quality of life in participants with femoroacetabular impingement syndrome scheduled for hip arthroscopy.
