Surgical Technique for Management of Congenital Pseudarthrosis of the Clavicle.

Congenital pseudarthrosis of the clavicle is a rare phenomenon with multiple proposed causes. Surgical management is typically indicated either because of the cosmetic appearance of the irregularity or, less commonly, for pain, particularly in adolescent patients. Multiple surgical methods have previously described in the literature, which have raised concern owing to the persistently high rate of nonunion postoperatively. This article describes management of congenital pseudarthrosis of the clavicle with open reduction and internal fixation using a T-shaped iliac crest autograft.

Staged Bilateral Total Knee Arthroplasty: Differing Results Comparing the First and Second Knees.

BACKGROUND: Patients often prefer one knee over the other following staged bilateral total knee arthroplasty (BTKA). Our study compared patient-reported outcomes scores of each knee following BTKA and identified factors that may contribute to the identified discrepancies. METHODS: All patients who underwent staged BTKA between July 2014 and August 2022 were identified. The patient-reported outcomes were collected preoperatively and at 2 weeks, 6 weeks, 1 year, and 2 years postoperatively. Each knee's results were compared using paired t-tests and McNemar tests. Preoperative Kellgren-Lawrence Grade (KLG), postoperative range of motion (ROM), reoperation rates, and manipulations under anesthesia (MUAs) were collected. Results were stratified based on time between TKAs (< 3 months, 3 to 12 months, 1 to 2 years, and > 2 years). RESULTS: There were 911 patients who underwent staged BTKA, with a mean 4.1-year follow-up. The ROM, patient satisfaction, MUAs, and reoperations were not significantly different between knees. Comparing the KLG of the first and second knees, 71% had the same KLG for both knees, 21% had a lower KLG, and 7% of the second knees had a higher KLG. The first knee had greater pain reduction (-10.6 at 2 weeks, -27.4 at 6 weeks) compared to the second (9.3 at 2 weeks, -8.1 at 6 weeks) (P < .0001) and better improvement in Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) score (8.5 at 2 weeks, 16.9 at 6 weeks) compared to the second (-5.8 at 2 weeks, 5.0 at 6 weeks) (P < .0001). The 1-year outcomes between first and second knees, or recovery curves, were not different when stratifying by time between TKAs. CONCLUSIONS: The second knee in a staged BTKA has less delta improvement in KOOS JR and pain scores at early follow-up, likely due to higher starting KOOS JR and Patient-Reported Outcomes Measurement Information System scores, despite similar final patient satisfaction and clinical outcome measures. Lower KLG in the second total knee arthroplasty (TKA) may contribute to these findings. An MUA after the first TKA is highly predictive of an MUA after the second TKA.

Early Radiographic and Clinical Outcomes of an Additive-Manufactured Acetabular Component.

Background: Additive manufacturing has recently gained popularity and is widely adopted in the orthopaedic industry. However, there is a paucity of literature on the radiographic and clinical outcomes of these relatively novel components. The aim of this study was to assess the 2-year clinical and radiographic outcomes of a specific additive-manufactured acetabular component in primary total hip arthroplasty. Methods: We performed a retrospective review of 60 patients who underwent primary total hip arthroplasty with the use of the Stryker's TRIDENT II acetabular component. Evaluation of radiographs was performed at 6 weeks, 1 year, and 2 years postoperatively. Radiographs were evaluated for radiolucencies in Charnley and DeLee zones, signs of biologic fixation, and acetabular inclination and anteversion measurements. Patient-reported outcomes and complications were also obtained. Results: There were no cases of component loosening or changes in component position during follow-up, with an average follow-up time of 1.7 years. A radiolucent line was identified in one patient in zone 1 at 6 weeks; this was absent at 1 year. Radiographic signs of cup biologic fixation were present in 85% of cases by final follow-up. The average inclination was 45.1 (SD = 4.0), and the average anteversion was 26.9 (SD = 5.2). Patient-Reported Outcomes Measurement Information System scores significantly increased at the final follow-up, and there were no complications in this cohort. Conclusions: This study demonstrated excellent radiographic and clinical outcomes with this novel additive-manufactured acetabular component at early follow-up. Although longer-term follow-up is warranted, this additively manufactured highly porous titanium acetabular component demonstrated excellent biologic fixation and reliable fixation at mid-term follow-up.

Outpatient Total Joint Arthroplasty at a High-Volume Academic Center: An Analysis of Failure to Launch.

BACKGROUND: Unanticipated failure to discharge home (failure to launch, FTL) following scheduled same-day discharge (SDD) total joint arthroplasty (TJA) is problematic for the surgical facility with respect to staffing, care coordination, and reimbursement concerns. The aim of this study was to review rates, etiologies, and contributing factors for FTL in SDD TJA at an inpatient academic medical center. METHODS: All patients who underwent primary TJA between February 2021 and February 2023 were retrospectively reviewed. Of those scheduled for SDD, risk factors for FTL were compared with successful SDD. Readmission and emergency department (ED) visits were compared with historical cohorts. There were 3,093 consecutive primary joint arthroplasties performed, of which 2,411 (78%) were scheduled for SDD. RESULTS: Overall, SDD was successful in 94.2% (n = 2,272) of patients who had an FTL rate of 5.8%. Specifically, SDD was successful in 91.4% with total hip arthroplasty, 96.0% with total knee arthroplasty, and 98.6% with unicompartmental knee arthroplasty. Factors that significantly increased the risk of FTL included general anesthesia versus spinal anesthesia (P < .0001), later surgery start time (P < .0001), longer surgical time (P = .0043), higher estimated blood loss (P < .0001), women (P = .0102), younger age (P = .0079), and lower preoperative mental health patient-reported outcomes scores (P = .0039). Readmission and ED visit rates were not higher in the SDD group when compared to historical controls (P = .6830). CONCLUSIONS: With a comprehensive multidisciplinary approach dedicated to improving SDDs at an academic medical center, we have seen successful SDD in nearly 80% of primary TJA, with an FTL rate of 5.8%, and no increased risk of readmission or ED visits. Without adding many personnel, hospital recovery units, or other resources, simple interventions to help decrease FTL have included enhanced preoperative education and expectation settings, improved perioperative communications, reallocating personnel from the inpatient to the outpatient setting, the use of short-acting spinal anesthetics, and earlier scheduled surgery times.

The Accuracy of Three-Dimensional CT Scan Software in Predicting Prosthetic Utilization in Total Shoulder Arthroplasty.

INTRODUCTION: Recent innovations in shoulder arthroplasty include three-dimensional (3D) CT software imaging that can be used to predict which prosthetic implants will be used intraoperatively. Correct prediction of the implants may optimize supply chain logistics for the surgeon, hospital, ambulatory surgery center, and the implant company. The purpose of this study was to examine a single surgeon's experience with this software to determine its predictive accuracy in determining which implants would be used intraoperatively. METHODS: A retrospective review of patients undergoing total shoulder arthroplasty (TSA) performed by a single surgeon was performed. Inclusion criteria were patients undergoing anatomic (aTSA) or reverse (rTSA) TSA examined preoperatively with the 3D CT planning software. A chart review was performed to compare the accuracy of the preoperative plan in predicting the actual prostheses implanted at surgery. RESULTS: Two hundred seventy-eight shoulders from 260 patients were included. One hundred fifty-one shoulders underwent aTSA, and 127 shoulders underwent rTSA. The surgeon was able to predict the type of arthroplasty (anatomic versus reverse) implanted in 269 of 278 (97%) shoulders. Using the 3D CT software, the surgeon was able to predict all the implants implanted in 68 shoulders (24%). For aTSA, 3D CT imaging successfully predicted all implants implanted in 43 shoulders (28%), glenoid implants implanted in 120 of 148 shoulders (81%), and humeral implants implanted in 54 shoulders (36%). For rTSA, 3D CT imaging successfully predicted all implants implanted in 26 shoulders (20%), glenoid implants implanted in 106 shoulders (83%), and humeral implants implanted in 39 shoulders (31%). CONCLUSIONS: The 3D CT software combined with surgeon's judgment provided a high accuracy (97%) in determining the type of arthroplasty, a moderately high accuracy in determining the glenoid implants (81% to 83%), a low accuracy in determining humeral implants (31% to 36%), and a low accuracy in determining all prostheses used for each surgery (20% to 28%). LEVEL OF EVIDENCE: LOE IV-Diagnostic Case Series.

Midterm Outcomes of Posterior Medial Meniscus Root Tear Repair: A Systematic Review.

BACKGROUND: Whereas there has been growing interest in surgical repair of posterior medial meniscus root tears (PMMRTs), our understanding of the medium- and long-term results of this procedure is still evolving. PURPOSE: To report midterm clinical outcomes from PMMRT repairs. STUDY DESIGN: Systematic review. METHODS: A literature review for this systematic analysis was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We identified studies that reported the results of arthroscopic repair of PMMRTs. Functional and imaging outcomes were reviewed and summarized. RESULTS: In total, 28 studies with a total of 994 patients (83% female) with an overall mean age of 57.1 were included in this review. Clinical outcomes (Lysholm, International Knee Documentation Committee, Hospital for Special Surgery, and Tegner scores) were improved at final follow-up in all studies. Of patients, 49% had radiographic progression of at least 1 grade in the Kellgren-Lawrence scale at a mean follow-up of 4.0 years in 11 studies. Cartilage degeneration had progressed at least 1 grade on magnetic resonance imaging scans in 23% of patients at a mean follow-up of 31.6 months in 4 studies. CONCLUSION: PMMRT repairs provide a functional benefit with consistent improvements in clinical outcome scores. There is some evidence that PMMRT repair slows the progression of osteoarthritis but does not prevent it at midterm follow-up.

Clinical Implications of Bone Bruise Patterns Accompanying Anterior Cruciate Ligament Tears.

BACKGROUND: Anterior cruciate ligament (ACL) tears are common injuries; they are often associated with concomitant injuries to other structures in the knee, including bone bruises. While there is limited evidence that bone bruises are associated with slightly worse clinical outcomes, the implications of bone bruises for the articular cartilage and the risk of developing osteoarthritis (OA) in the knee are less clear. Recent studies suggest that the bone bruise pattern may be helpful in predicting the presence of meniscal ramp lesions. EVIDENCE ACQUISITION: A literature review was performed in EMBASE using the keyword search phrase (acl OR (anterior AND cruciate AND ligament)) AND ((bone AND bruise) OR (bone AND contusion) OR (bone AND marrow AND edema) OR (bone AND marrow AND lesion) OR (subchondral AND edema)). STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: The literature search returned 93 articles of which 25 were ultimately included in this review. Most studies identified a high prevalence of bone bruises in the setting of acute ACL injury. Individual studies have found relationships between bone bruise volume and functional outcomes; however, these results were not supported by systematic review. Similarly, the literature has contradictory findings on the relationship between bone bruises and the progression of OA after ACL reconstruction. Investigations into concomitant injury found anterolateral ligament and meniscal ramp lesions to be associated with bone bruise presence on magnetic resonance imaging. CONCLUSION: Despite the ample literature identifying the prevalence of bone bruises in association with ACL injury, there is little evidence to correlate bone bruises to functional outcomes or progression of OA. Bone bruises may best be used as a marker for concomitant injury such as medial meniscal ramp lesions that are not always well visualized on magnetic resonance imaging. Further research is required to establish the longitudinal effects of bone bruises on ACL tear recovery. STRENGTH OF RECOMMENDATION TAXONOMY: 2.

Stretch too far: rectus sheath haematoma secondary to repetitive trauma and increased intra-abdominal pressure.

A 26-year-old man presented with a 4-week history of right lower quadrant abdominal pain which was managed conservatively at home with ibuprofen. Three days later, he presented to the emergency department with worsening pain and swelling following an episode of coughing and slipping in the bathroom. Following his admission, CT angiography showed an active bleed into a 4.6×6.7×11 cm right rectus sheath haematoma, just inferior to the umbilicus. The patient was then referred to interventional radiology for an angiogram and coil embolisation. A superselective branch angiogram showed contrast extravasation from a medial branch of the right inferior epigastric artery, successfully embolised without incident.

A Distal Radius Nonunion Treated with A Dorsal Spanning Distraction Plate: A Case Report.

Distal radius fractures are one of the most common orthopedic injuries, particularly in the elderly population. Distal radius nonunions are rare and are usually associated with a patient's underlying health conditions. We present a patient who developed a distal radius nonunion following treatment of an open wrist fracture with an external fixation frame. This nonunion was successfully treated with a dorsal spanning distraction plate. The etiology of distal radius nonunions and treatment options are reviewed.

Cushing's Syndrome in a Pregnant Patient Secondary to Adrenal Adenoma: Treatment With Unilateral Adrenalectomy.

BACKGROUND: A pregnant woman presented with Cushing's syndrome (CS) secondary to adrenal adenoma and was treated with laparoscopic-assisted right adrenalectomy during the second trimester of pregnancy. SUMMARY: Our patient is a 33-year-old woman who presented with hypertension and cushingoid appearance at 21 weeks gestational age. Laboratory evidence indicated CS was likely, and imaging found a 2.3 x 3.0 cm right adrenal nodule as a suggested cause. Laparoscopic-assisted right adrenalectomy was performed at 23 weeks 4 days gestation without complication. Pathology of the removed specimen revealed an adrenal gland containing a 3.0 x 3.0 x 2.0 cm well-circumscribed proliferation of adrenal cortical cells without significant atypia. This report describes the rare occurrence of CS during pregnancy and subsequent successful surgical management. We review the diagnosis of CS during pregnancy and surgical considerations. CONCLUSION: CS, while a rare entity in the general population, is even more unique in the setting of pregnancy due to the negative effects of hypercortisolism on fertility. CS during pregnancy presents a diagnostically complicated scenario, along with specific considerations necessary for successful surgical management.

Miller Fisher Syndrome Presenting to a Rural South Dakota Hospital.

This report describes a rare case of an 87-year-old woman presenting to a rural emergency department with ataxia. Throughout her admission, she developed areflexia and ophthalmoplegia consistent with a diagnosis of Miller Fisher syndrome. The patient underwent a rapid recovery after receiving treatment with intravenous immunoglobulin (IVIg) for a duration of five days and a two-month period of outpatient physical therapy.

Determining Efficacy of Intervention in the Limitation of Opioid and Benzodiazepine Co-Prescription.

INTRODUCTION: Multiplying the effects of central nervous system and respiratory depression, benzodiazepines are involved in 30 percent of opioid overdoses. The mortality rate in co-administration of both medications is 10 times higher than those taking only opioids. The medication labels even contain direct instructions or "black box" labels warning against their use in conjunction. However, opioids and benzodiazepines are commonly prescribed together by providers, regardless of these contraindications. The purpose of this manuscript was to bring further attention to the opioid crisis and to study the effect of a simple and cost-effective intervention in reducing the co-administration of benzodiazepines and opioids. METHODS: A didactic clinical presentation along with handouts outlining the epidemiology of co-administration of benzodiazepines and opioids, side effects of each medication class, alternatives to consider prior to initiating therapy, guidelines on how to avoid medication misuse, recommendations for when to taper medications, and examples of how to taper these medications was made to attendings and residents of one family medicine clinic in a small, midwestern community. The number of patients co-prescribed these medications at this clinic was determined by searching the electronic medical record, the intervention was given, and three months later the number was measured again for comparison. RESULTS: The intervention did not result in a significant decrease in those co-prescribed benzodiazepines and opioids. CONCLUSIONS: This study opens the door to future studies investigating longer time frames, decreases in dosages, and patients appropriately prescribed these medications. Alternative interventions such as medical record notifications and more frequent education sessions provide direction for continued research in an effort to impact the epidemic our country is facing with the use of opioids, benzodiazepines and other prescription pain medications.

Pneumatosis Cystoides Intestinalis Identified on Screening Colonoscopy With Associated Pneumoperitoneum.

Pneumatosis cystoides intestinalis (PCI) is defined by the presence of gas within the bowel wall. It is often asymptomatic and usually benign but may be associated with significant morbidity and mortality. In this patient, PCI was found incidentally on screening colonoscopy, and biopsy of the affected mucosa resulted in deflation of a cyst. Pneumoperitoneum was then identified on subsequent CT. Because pneumoperitoneum is associated with bowel perforation in most cases, it is often treated as an indication for operation. This case of benign and asymptomatic pneumoperitoneum was managed conservatively without complications. Clinicians should be able to identify PCI as a potentially benign finding on colonoscopy as well as a potentially benign cause of pneumoperitoneum. This understanding presents an opportunity to avoid the unnecessary morbidity and costs associated with surgical exploration or additional endoscopic procedures.
