The purpose of this study was to investigate practice change rates among board- eligible orthopaedic surgeons using the American Board of Orthopaedic Surgery (ABOS) database.METHODSWe utilized information provided by orthopaedic surgeons taking the ABOS Part II Examination across 6 different years. Surgeons who trained outside of the United States and members of the uniformed services of the U.S. were excluded. Move rates within 2 years of starting practice and before the candidate's Part II examination were determined. All surgeons were then subcategorized as having followed a traditional or nontraditional certification timeline based on whether they took Part II of the examination within 2 practice years after becoming board-eligible. Candidate-specific variables were analyzed according to whether the surgeon did or did not change practices.RESULTSAmong 3,784 orthopaedic surgeons, 215 (5.7%) left their first practice within 2 years. On average, candidates sat for the Part II examination at a mean (and standard deviation) of 2.1 ± 1.1 years (range, 0.7 to 31.9 years) after reporting their first practice location. Seventy-six percent of surgeons took the Part II examination within a traditional timeframe. On average, nontraditional candidates left their first practice at a significantly higher rate than traditional candidates (20.5% versus 1.3%; p < 0.001), changed practices more often (1.5 versus 1.2 moves; p = 0.021), and moved farther (500.1 versus 304.4 miles; p = 0.023). Fellowship training and/or Part II examination subspecialty were not strongly associated with a surgeon leaving his or her first practice.CONCLUSIONSWhile it is possible that >5.7% of orthopaedic surgeons leave their first job during their early career, it is unlikely that many relocate within 2 years. This is especially true among orthopaedic surgeons pursuing ABOS certification within a traditional timeframe.","PeriodicalId":22625,"journal":{"name":"The Journal of Bone & Joint Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine if there was a relationship among surgeon volume, technology usage, and revision rate when using an optimal prosthesis combination (OPC).METHODSAustralian Orthopaedic Association National Joint Replacement Registry (AOANJRR) data were obtained from January 1, 2008, to December 31, 2022, for all primary TKA procedures performed for osteoarthritis using an OPC by a known surgeon ≥5 years after their first recorded procedure. The interaction between surgeon volume and conventional-instrumentation (CV) versus technology-assisted (TA) TKA was assessed. The cumulative percent revision (CPR) was determined by Kaplan-Meier estimates. Cox proportional-hazards methods were used to compare rates of revision by surgeon volume and by the interaction of volume and technology. Subanalyses were undertaken to examine major and minor revisions separately, and to assess the influence of technology on revision rates relative to those of a surgeon undertaking 100 TKA/year.RESULTSOf the 53,264 procedures that met the inclusion criteria, 31,536 were TA-TKA and 21,728 were CV-TKA. Use of technology reduced the all-cause revision rate for surgeons with a volume of <50 TKA/year and the rate of minor revisions for surgeons with a volume of <40 TKA/year. No interaction between surgeon volume and the rate of major revision surgery was found. With CV-TKA by a surgeon with a 100-TKA/year volume as the comparator, all-cause and major revision rates were significantly elevated for surgeons undertaking <50 and <100 TKA/year, respectively. In contrast, analysis of TA-TKA showed no difference in rates of all-cause or major revisions for surgeons undertaking <100 TKA/year compared with 100 TKA/year.CONCLUSIONSTA-TKA was associated with a decrease in the revision rate for lower-volume surgeons but no significant alterations in revision rate for higher-volume surgeons.

Data were collected at baseline, 3 months, 6 months, and every year after surgery. Risks of postoperative complications and unplanned reoperations were assessed. A multivariable regression model was used to identify risk factors for complications and to determine the association of complications with patient-reported outcomes.RESULTSA total of 412 patients (425 shoulders) undergoing arthroscopic Bristow or Latarjet procedures performed by a single surgeon between November 2016 and April 2021 were reviewed. Two hundred and ninety-nine patients (308 shoulders, 76.2% of 404 eligible) with a mean follow-up of 22.3 ± 4.2 months were included for analysis. Two hundred and sixty-nine shoulders (87.3%) underwent a Bristow procedure (165 with screw and 104 with suture-button fixation), while 39 (12.7%) underwent a Latarjet procedure (18 with screw and 21 with suture-button fixation). Eighty-two patients (83 shoulders) reported a total of 85 complications within 2 years after surgery, with an overall complication rate of 26.9%. The rates of recurrent dislocation or subluxation and infection were 1.9% and 0.6%, respectively, while a total of 4 (1.3%) of the shoulders had unplanned reoperations. The most common complications were graft-related (11.7%), followed by complications involving neurologic symptoms (10.7%). The overall, graft, and neurologic complication rates following Bristow or Latarjet procedures were 27.1% versus 25.6%, 12.3% versus 7.7%, and 10.0% versus 15.4%, respectively. Compared with the Bristow technique with screw fixation, Bristow with suture-button fixation yielded a lower risk of any complications (odds ratio [OR], 0.55; p = 0.04). Paying with rural insurance and poor sleep quality prior to surgery were associated with increased risk of any complications.CONCLUSIONSCompared with arthroscopic Bristow procedures with screw fixation, Bristow procedures with suture-button fixation resulted in a lower overall complication risk.

However, the exact rate and characteristics of these injuries remain unclear. The primary objective of this study was to explore the rate and characteristics of PLC injuries in HVTPFs. The secondary objective was to investigate the relationship between the fracture morphological features and the associated PLC injuries.METHODSPatients with HVTPFs were subdivided into 2 groups: group I (without fracture of the posterior column cortex) and group II (with fracture of the posterior column cortex). Fracture characteristics were summarized qualitatively based on fracture maps and quantitatively based on the counts of morphological parameters. Knee ligamentous and meniscal injuries were assessed using magnetic resonance imaging. The association between fracture characteristics and PLC injuries was analyzed.RESULTSWe included a total of 50 patients with HVTPFs in our study: 28 in group I and 22 in group II. The rate of PLC injuries was 28.6% in group I and 27.3% in group II. In group I, patients with PLC injuries showed fracture lines closer to the anterior rim of the medial plateau and had smaller fracture areas. Furthermore, 6 of the 8 patients with PLC injuries in group I also had posterior cruciate ligament injuries.CONCLUSIONSThe rate of PLC injuries is relatively high in HVTPFs. In HVTPFs without fracture of the posterior column cortex, a small fracture area strongly suggests an accompanying PLC injury, and PLC injury is frequently combined with posterior cruciate ligament injury.LEVEL OF EVIDENCEPrognostic Level III.

{"title":"Simplifying the Orientation of S1 Iliosacral Screws for Placement in the Dysmorphic Sacrum.","authors":"Hongmin Cai,Yingchao Yin,Ruipeng Zhang,Lin Liu,Tao Wang,Zhiyong Hou","doi":"10.2106/jbjs.23.01416","DOIUrl":"https://doi.org/10.2106/jbjs.23.01416","url":null,"abstract":"BACKGROUNDDetermining the proper iliosacral screw orientation in a dysmorphic S1 sacral segment using a C-arm is difficult, and pelvic computed tomography (CT) is often necessary for the preoperative planning. On the preoperative pelvic axial CT section, the intended screw trajectory can be delineated intraosseously along the axis of the oblique osseous corridor. An inherently accurate orientation would be determined by 2 factors: (1) the trajectory is in the pelvic transverse plane, and (2) it is oriented relative to the coronal plane at a patient-specific angle, which should be measured preoperatively. Based on the above reasoning, we aimed to simplify and verify the orientation.METHODSAfter establishing the starting point on the sacral lateral view, we tested a method of simplifying the guidewire orientation: placing the guidewire in the pelvic transverse plane and then manipulating it to be angled relative to the coronal plane at the preoperatively measured patient-specific angle. The guidewire orientation should then be reproducibly accurate on the pelvic outlet and inlet views. The feasibility and safety of our method were verified through computer-simulated virtual surgical procedures in 95 dysmorphic sacra and clinical surgical procedures in 12 patients. The primary outcome parameters were the guidewire orientation and screw placement accuracy.RESULTSUsing our method, the S1 guidewire orientation was reproducibly accurate on the pelvic outlet and inlet views in all of the virtual and clinical surgical procedures. Ninety-five virtual S1 screws (1 screw in each left hemipelvis) were placed intraosseously in the pelvic transverse plane. Fourteen unilateral S1 screws were placed intraosseously in the pelvic transverse plane in the 12 patients (2 patients had double screws) without iatrogenic injuries.CONCLUSIONSThe guidewire orientation can be simplified by placing the guidewire in the pelvic transverse plane and replicating the preoperatively measured patient-specific angle between the guidewire and the coronal plane. After establishing the starting point on the sacral lateral view, our simplified manipulation yields a reproducibly accurate orientation on the pelvic outlet and inlet views.LEVEL OF EVIDENCETherapeutic Level III.

This risk may be increased by the presence of previous incisions. Performing a sham incision procedure allows for detection of wound-healing problems prior to performing TKA. The purpose of this retrospective case series is to describe the indications for and technique of a sham incision procedure in patients with previous knee incisions who underwent TKA following this procedure and to report the clinical outcomes observed in these patients following further surgery.METHODSPatients who had prior knee incisions, had undergone a sham incision prior to TKA, and had a minimum follow-up of 2 years were identified, and their cases were retrospectively reviewed. The identified cases typically adhered to the surgeon's standard protocol, which consisted of making a midline incision adventitious to TKA, dissecting down to deep fascia, and closing the wound with suture. Incisions were then observed for at least 4 weeks to determine the viability of the skin flaps before TKA was performed via the same incision.RESULTSA total of 47 knees in 47 patients were included in the study cohort. TKA was performed at an average of 21.1 weeks (range, 4 to 163 weeks) following the sham incision. There were no cases of skin necrosis or periprosthetic joint infection at an average follow-up of 4.6 years (range, 2 to 12 years) after sham incision.

In addition, obesity is a well-established risk factor for complications after TKA. The purpose of this study was to analyze trends in body mass index (BMI) and complication risk among obese patients undergoing primary TKA treated at a single institution over 3 decades.METHODSUtilizing an institutional total joint registry, 13,919 primary TKAs performed to treat osteoarthritis between 1990 and 2019 were identified. Patients were stratified by BMI according to the World Health Organization (WHO) classification into 3 groups: non-obese (BMI, <30 kg/m2), WHO Class-I and II obese (BMI, 30 to 39.9 kg/m2), and WHO Class-III obese (BMI, ≥40 kg/m2). Trends in BMI and survivorship free from reoperation, revision, and periprosthetic joint infection (PJI) were analyzed over time while controlling for age, sex, and the Charlson Comorbidity Index.RESULTSOver the study period, there was a 90% increase in the prevalence of Class-II obesity (13% to 25%) and a 300% increase in Class-III obesity (3% to 12%). Analysis of the entire cohort demonstrated a decrease in the 2-year risk of any reoperation, any revision, and PJI (p < 0.05 for all) with time. The risk decreased significantly over time for non-obese patients for any reoperation (p = 0.029) and any revision (p = 0.004) and for Class-III obese patients for any reoperation (p = 0.038) and any revision (p = 0.012), but it remained stable for Class-I and II obese patients. The risk of PJI decreased from 1990 to 2019 for non-obese patients (p = 0.005), but there were no significant changes in PJI risk for any obesity group.CONCLUSIONSDespite increasing rates of obesity among our patients who underwent TKA, we observed decreasing risks of reoperation, revision, and PJI over time. The risks of reoperation and revision declined among non-obese patients, remained stable for Class-I and II obese patients, and declined for Class-III obese patients. The PJI risk declined for non-obese patients over the study period, but no such decline occurred for any category of obesity.

Conventional TES carries the risk of damage to the great vessels anterior to the vertebral column, mainly because of a lack of visualization of the anterior structures. In this study, we devised a modified standard TES technique to achieve direct visualization in a 1-stage posterior approach.METHODSIncluded in this study were patients ≥18 years old with solitary thoracic or lumbar SM who underwent the modified standard TES at our institution between January 2017 and October 2022. Patient data were retrospectively sourced from medical records, and patients had a minimum of 3 months of postoperative follow-up.RESULTSThis study involved 71 East Asian patients (median age, 57 years; 34 males), comprising 38 patients with thoracic SM and 33 with lumbar SM. Lung cancer was the most common tumor histology. Fourteen patients (19.7%) experienced intraoperative complications; pleural rupture was the predominant complication, and there were no cases of injury to the spinal cord or great vessels. The median operative time was 305 minutes (range, 203 to 660 minutes). The median intraoperative blood loss was 1,000 mL (range, 400 to 4,000 mL). The median perioperative blood transfusion was 4 units (range, 0 to 12 units), and the median hospitalization duration was 17 days (range, 14 to 29 days). Additionally, 27 patients (38.0%) had acute (perioperative) complications. Seven patients were lost to follow-up. Significant clinical improvement was achieved 3 months postoperatively. Postoperative early and late complications were observed in 5 patients. Of the 64 patients with completed follow-up, 47 (73.4%) had negative surgical margins, and none received postoperative radiation therapy.
