To understand the merits of each approach, detailed information on the short and, importantly, longer-term outcomes of each must be known. The purpose of the present study was to assess the long-term results of 2-stage exchange arthroplasty following THA in one of the largest series to date.METHODSWe identified 331 periprosthetic joint infections (PJIs) that had been treated with a 2-stage exchange arthroplasty between 1993 and 2021 at a single institution. Patients were excluded if they had had prior treatment for infection. The mean age at the time of reimplantation was 66 years, 38% of the patients were female, and the mean body mass index (BMI) was 30 kg/m2. The diagnosis of PJI was based on the 2011 Musculoskeletal Infection Society criteria. A competing-risk model accounting for death was utilized. The mean duration of follow-up was 8 years.RESULTSThe cumulative incidence of reinfection was 7% at 1 year and 11% at 5 and 10 years. Factors predictive of reinfection included BMI ≥30 kg/m2 (hazard ratio [HR] = 2; p = 0.049) and the need for a spacer exchange (HR = 3.2; p = 0.006). The cumulative incidence of any revision was 13% at 5 and 10 years. The cumulative incidence of aseptic revision was 3% at 1 year, 7% at 5 years, and 8% at 10 years. Dislocation occurred in 33 hips (11% at 10 years); 15 (45%) required revision. Factors predictive of dislocation were female sex (HR = 2; p = 0.047) and BMI <30 kg/m2 (HR = 3; p = 0.02). The mean Harris hip score (HHS) improved from 54 to 75 at 10 years.CONCLUSIONSIn this series of 331 two-stage exchange arthroplasties that were performed for the treatment of infection, we found a low rate of aseptic revision (8%) and a low rate of reinfection (11%) at 10 years. These long-term mechanical and infection data must be kept in mind when considering a paradigm shift to 1-stage exchanges.LEVEL OF EVIDENCETherapeutic Level III.

The purpose of the present study was to explore the risk factors associated with reoperations following procedures under anesthesia (\"operations\") for DDH in patients between the ages of 1 and 3.00 years, with the goal of deriving treatment recommendations.METHODSThis retrospective birth cohort study included children who had undergone closed reduction, open reduction, or osteotomy for the treatment of unilateral DDH between the ages of 1 and 3.00 years, identified using the Taiwan National Health Insurance Research Database. The children were followed until 10 years of age for reoperations, excluding implant removal and sequential closed reduction within 3 months postoperatively. A comparison between patients with and without reoperations was conducted, and binary logistic regression was used to identify factors associated with reoperation. Patients were further stratified by age and procedure for developing treatment recommendations.RESULTSAmong 2,261,455 live births from 2000 to 2009, 701 patients underwent operations for unilateral DDH between 1 and 3.00 years of age (an incidence of 31.0 per 1,000 live births). The initial operations included closed reduction (n = 86; mean age, 1.34 years), open reduction (n = 73; mean age, 1.53 years), pelvic osteotomy (n = 405; mean age, 1.59 years), femoral osteotomy (n = 93; mean age, 1.76 years), and pelvic osteotomy plus femoral osteotomy (n = 44; mean age, 1.84 years). Reoperations were performed in 91 patients (13%) at a mean age of 3.80 years. Comparison between patients with and without reoperations revealed the operative procedure as a significant factor. Logistic regression revealed that closed reduction was associated with a 1.8 to 9.0 times higher reoperation risk than open reduction, depending on age, whereas pelvic osteotomy was associated with 0.34 times the risk of reoperation than open reduction in patients 1.5 to 2.0 years of age.CONCLUSIONSReoperations may not be directly linked to radiographic and functional outcomes but are important from the patient's perspective and in terms of cost-effectiveness. To reduce the risk of reoperation, the findings of the present study support open reduction to properly reduce the hip joint at walking age and additional pelvic osteotomy for patients beyond 1.5 years of age.LEVEL OF EVIDENCEPrognostic Level III.

A large proportion of pediatric hematogenous osteomyelitis infections can spread through the growth cartilage and therefore may be potentially responsible for growth disorders, leading to limb-length discrepancy or angular deformities. The purpose of the present study was to identify both the prevalence of complications caused by transphyseal osteomyelitis and factors influencing their occurrence.METHODSThe records for all patients who had been treated for THO over a 17-year period at the University Hospitals of Geneva and the Gesù Bambino Hospital in Rome were retrospectively analyzed. Clinical, biological, and bacteriological data were analyzed. Magnetic resonance imaging (MRI) scans were reviewed for all patients to assess the cross-sectional area of growth plate involvement. Restart of growth of the affected physeal cartilage was subsequently monitored by means of iterative radiographic examination.RESULTSFrom a cohort of 594 patients with hematogenous osteomyelitis, 89 patients (15.0%) were found to have THO. The median age was 84 months (range, 1 to 167 months), with a bimodal distribution and peaks at 30 and 150 months; 59.6% (53) of the 89 patients were male. The lower limbs were most often affected, with the distal tibia and fibula accounting for 47.2% of all cases. Methicillin-sensitive Staphylococcus aureus and Kingella kingae were the most frequently identified pathogens, accounting for 61.8% of the cases. Virulence factors, such as Panton-Valentine leukocidin (PVL), toxic shock syndrome toxin (TSST), and accessory gene regulator (Agr), were recorded in 12.4% of MSSA strains. Transphyseal lesions affected a median of 7.6% (range, 0.79% to 58.2%) of the physeal surface. Complications affecting further growth were noted in 13% of patients with THO. Thrombocytopenia, leukocytosis, and the presence of virulence factors significantly influenced the occurrence of complications.CONCLUSIONSTHO affects all age categories of the pediatric population. In the present study, growth disturbance occurred in 13% of cases. The presence of deep thrombocytopenia, leukocytosis, and virulence factors, such as Agr, TSST, and PVL, seems to strongly influence the occurrence of such complications.LEVEL OF EVIDENCETherapeutic Level IV.

This limits the ability to compare or combine cohorts that utilize different PROMs. The aim of this study was to develop a linkage model for the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand) and PROMIS PF CAT (Patient-Reported Outcomes Measurement Information System Physical Function computerized adaptive testing) instruments to allow interconversion between these PROMs in a hand surgery population.METHODSA retrospective review was conducted to identify adults (≥18 years old) who had completed the QuickDASH and PROMIS PF CAT instruments at the same clinical encounter. Patients with shoulder pathology were excluded. The linear relationship between scores was evaluated with use of the Pearson correlation coefficient. Linking was performed with use of several common methods, and an optimal linkage model was recommended on the basis of a higher R2, strong intraclass correlation coefficient (ICC), and lower standard error (SE). The recommended model was further evaluated in subgroups based on age (<60 or ≥60 years), sex, etiology for presentation (traumatic versus atraumatic), and treatment type (operative versus nonoperative).RESULTSA total of 15,019 patients (mean age, 49 years; 54% female; 86% White) were included. The mean QuickDASH score (and standard deviation) was 37 ± 22, and the mean PROMIS PF CAT score was 45 ± 10. There was a strong negative linear relationship between the QuickDASH and PROMIS PF CAT (r = -0.73). The circle-arc linkage model demonstrated good accuracy and reliability (R2 = 0.55; ICC = 0.71), and crosswalk tables were developed from this model. The subgroup analysis demonstrated age-related bias in the linkage model (root expected mean squared difference, 0.12). To address this, a separate crosswalk table was developed, which was dichotomized by age category.CONCLUSIONSThe QuickDASH and PROMIS PF CAT scores were successfully linked. Utilization of the developed crosswalks-one specific to patients <60 years old and another specific to patients ≥60 years old-will allow for score interconversion in future meta-analyses and multicenter hand surgery studies.LEVEL OF EVIDENCEPrognostic Level III.

The nature of these decisions underscores the importance of shared decision-making, which is founded on the concept that patients substantially contribute to determining their own readiness for surgery. The OPTION survey was developed as a conversation aid to facilitate shared decision-making in the context of total joint arthroplasty.METHODSThe OPTION survey was created in partnership with a panel of 10 active joint replacement patients and 15 arthroplasty surgeons, using a modified Delphi methodology that employed 3 sequential meetings by each group. The survey interrogates patient and surgeon ratings of pain, activity limitation, duration of treatment, prior treatments, and quality of life; patient-rated treatment priorities, readiness for surgery, and surgeon engagement; and surgeon-graded radiographic disease. The survey was administered as an institutional review board-approved pilot during 641 patient-clinician encounters for hip or knee arthritis at 9 U.S. sites, and was independently completed by the patient and surgeon.RESULTSPatient self-assessment of readiness for surgery includes consideration of existing functional impairment, outcome priorities, realistic expectations, and personal socioeconomic circumstances. Patients most commonly ranked removal of activity limitations as their top treatment priority, while alleviation of pain and avoidance of a long recovery were also ranked highly. Mild and severe pain were associated with similar radiographic disease severity, and worsening radiographic disease was associated with increasing patient-reported readiness for surgery. Patients and surgeons agreed on symptom severity in >90% of cases. When disagreement occurred, surgeons typically underestimated patient-reported symptoms; these cases were associated with lower patient-rated surgeon engagement in shared decision-making conversations.CONCLUSIONSShared decision-making conversations substantially contributed to the assessment of patient readiness for joint replacement surgery. When patient and surgeon assessments were not aligned, surgeons most commonly underestimated patient-perceived impairment. These observations should inform optimal surgeon-patient communications.LEVEL OF EVIDENCEPrognostic Level III.

To address a gap in the limited research on this topic, we utilized high-resolution impedance manometry (HRIM) and the Eating Assessment Tool-10 (EAT-10) questionnaire to assess the effects on key swallowing muscles, including the upper esophageal sphincter (UES).METHODSWe randomly assigned patients undergoing ACDF to either the corticosteroid group or the saline solution group. Patients received 10 mg of local triamcinolone or saline solution prevertebrally at the cervical spine level before wound closure. Swallowing function preoperatively and at 1 month postoperatively were compared between the groups with use of HRIM parameters (e.g., UES relaxation, UES opening extent, intrabolus pressure, and pharyngeal contraction) and EAT-10 scores. Patients were also followed for postoperative complications and mortality within 12 months after surgery.RESULTSThirty patients completed the study. The median age was 55 years in the corticosteroid group and 57 years in the saline group, and each group had 8 female patients. All participants were Taiwanese. We found no significant difference in median preoperative UES relaxation pressure between the corticosteroid and saline solution groups (33.8 and 31.3 mm Hg, respectively; p = 0.54). Postoperatively, the corticosteroid group had significantly lower median UES relaxation pressure than the saline solution group (24.5 versus 33.6 mm Hg; p = 0.01). Before and after surgery, all other HRIM parameters and EAT-10 scores were similar between the groups, with the corticosteroid group demonstrating median pre- and postoperative EAT-10 scores of 0 and 4, respectively, and the saline solution group demonstrating scores of 2 and 3, respectively.

For its most prevalent form, adolescent idiopathic scoliosis, no underlying condition can be defined, and the pathomechanism appears to be multifactorial; however, it has been suggested that the biomechanics of the spine play a role. For nonidiopathic scoliosis, underlying conditions can be recognized, but what drives the deformity remains unclear. In this study, we examined the early sagittal shape of the spine before the onset of scoliosis in a population with 22q11.2 deletion syndrome (22q11.2DS). This cohort was chosen since children with this syndrome have an approximately 50% chance of developing scoliosis that shares certain characteristics with idiopathic scoliosis, namely, age of onset, curve morphology, and rate of progression.METHODSThis prospective cohort study included patients with 22q11.2DS who were followed with the use of spinal radiographs during adolescent growth. All of the children, who initially had no scoliosis while still skeletally immature (Risser stages 0 and 1), were followed at 2-year intervals until they reached skeletal maturity (Risser stages 3 to 5). We assessed the segment of the spine that has previously been shown to be rotationally unstable, the posteriorly inclined segment, to determine if it was predictive of later scoliosis development. For quantification, the area of the \"posteriorly inclined triangle\" (PIT), a previously described parameter that integrates both the inclination and length of the at-risk segment, was measured.RESULTSOf the 50 children who initially had no scoliosis (mean age at inclusion, 10.7 ± 1.7 years; mean follow-up, 4.8 ± 1.6 years), 24 (48%) developed scoliosis. Patients with an above-average PIT area (>60 cm2) at inclusion showed a relative risk of 2.55 for scoliosis development (95% confidence interval [CI]:1.22 to 5.34). PIT inclination was correlated with curve type: a taller and steeper hypotenuse predicted later thoracic scoliosis, while a shorter and less steep inclination predicted the development of (thoraco)lumbar scoliosis.CONCLUSIONSThis prospective study identified the pre-scoliotic sagittal shape of the spine as a risk factor for the later development of scoliosis in the population of children with 22q11.2DS.LEVEL OF EVIDENCEPrognostic Level II.

We sought to evaluate risks of re-revision and prosthetic dislocation following rTHA involving a DMC compared with other articulations.METHODSA cohort study was conducted using data from a U.S. integrated health-care system's Total Joint Replacement Registry. Adult patients who underwent primary THA and went on to undergo an aseptic rTHA in 2002 to 2022 were identified. Patients who received a DMC, a constrained liner, or a metal or ceramic unipolar femoral head on highly cross-linked polyethylene (XLPE) at the time of rTHA were the treatment groups. Subsequent aseptic re-revision and dislocation were the outcomes of interest. Multivariable Cox proportional-hazards regression was used to evaluate the risks of the outcomes, with adjustment for patient, operative, and surgeon confounders.RESULTSThe analyzed rTHAs comprised 375 with a DMC, 268 with a constrained liner, 995 with a <36-mm head on XLPE, and 2,087 with a ≥36-mm head on XLPE. DMC utilization increased from 1.0% of rTHAs in 2011 to 21.6% in 2022. In adjusted analyses, a higher re-revision risk was observed for the constrained liner (hazard ratio [HR] = 2.43, 95% confidence interval [CI] = 1.29 to 4.59), <36 mm on XLPE (HR = 2.05, 95% CI = 1.13 to 3.75), and ≥36 mm on XLPE (HR = 2.03, 95% CI = 1.19 to 3.48) groups compared with the DMC group.
