Acute-on-Chronic Axillary Artery Thrombus After Reverse Total Shoulder Arthroplasty for Failed Proximal Humerus Open Reduction and Internal Fixation: A Case Report.

CASE: A 71-year-old woman presented with post-traumatic arthritis 11 months after open reduction and internal fixation for a left proximal humerus fracture (PHF) dislocation. After revision to reverse total shoulder arthroplasty (rTSA), the patient's left upper extremity was found to be avascular. An emergent thrombectomy was performed with restoration of arterial flow after removal of an acute-on-chronic axillary artery thrombus. CONCLUSION: Although rare, as rTSA becomes more common for management of PHF, incidence of associated vascular injuries is likely to rise. Screening methods and clinical vigilance in diagnosis are advised for patients with anterior PHF dislocations and arterial injury risk factors.

Factors influencing shoulder stiffness after open reduction and internal fixation of proximal humeral fractures.

OBJECTIVES: The study aimed to investigate the factors associated with shoulder stiffness following open reduction and internal fixation (ORIF) of proximal humeral fractures. PATIENTS AND METHODS: The retrospective study included a total of 151 patients who underwent ORIF of proximal humeral fractures between January 2016 and May 2021. Based on their shoulder joint motion at the latest follow-up, the patients were divided into two groups. The stiffness group (n=32; 8 males, 24 females; mean age: 62.4±9.3 years; range, 31 to 79 years), exhibited restricted shoulder forward flexion (<120°), limited arm lateral external rotation (<30°), and reduced back internal rotation below the L3 level. The remaining patients were included in the non-stiffness group (n=119; 52 males, 67 females; mean age: 56.4±13.4 years; range, 18 to 90 years). Various factors were examined to evaluate the association with shoulder stiffness following ORIF of proximal humeral fractures by multivariate unconditional logistic regression models. RESULTS: The mean follow-up duration was 31.8±12.6 (range, 12 to 68) months. Based on the results of the multivariate regression analysis, it was found that high-energy injuries [compared to low-energy injuries; adjusted odds ratio (aOR)=7.706, 95% confidence interval (CI): 3.564-15.579, p<0.001], a time from injury to surgery longer than one week (compared to a time from injury to surgery equal to or less than one week; aOR=5.275, 95% CI: 1.7321-9.472, p=0.031), and a body mass index (BMI) >24.0 kg/m2 (compared to a BMI between 18.5 and 24.0 kg/m2 ; aOR=4.427, 95% CI: 1.671-11.722, p=0.023) were identified as risk factors for shoulder stiffness following ORIF of proximal humeral fractures. CONCLUSION: High-energy injury, time from injury to surgery longer than one week, and BMI >24.0 kg/m2 were identified as independent risk factors for shoulder stiffness after proximal humeral fracture surgery, which should be treated with caution in clinical treatment.

No Difference in Acute Outcomes for Patients Undergoing Fix and Replace Versus Fixation Alone in the Treatment of Geriatric Acetabular Fractures.

OBJECTIVES: To compare acute outcomes between patients undergoing fix and replace (FaR) versus open-reduction and internal fixation (ORIF) alone in the treatment of geriatric acetabular fractures. DESIGN: Retrospective Cohort Study. SETTING: Single Level 2 Trauma Center. PATIENT SELECTION CRITERIA: Consecutive acetabular fracture patients ≥ 55 years of age treated by two orthopaedic trauma surgeons at one tertiary care center from January 2017 to April 2022 with FaR versus ORIF were identified. Included were those with complete datasets within the 180-day global period. Excluded were patients with previous ORIF of the acetabulum or femur, or revision total hip arthroplasty. OUTCOME MEASURES AND COMPARISONS: The primary outcomes were length of hospital stay (LOS), postoperative weight-bearing status, postoperative disposition, time to postoperative mobilization, and 90-day readmission rates. Secondary outcomes compared included demographic information, injury mechanism, surgical time, complications, revisions, and preoperative and postoperative Hip Disability and Osteoarthritis Outcomes Score for Joint Replacement (HOOS Jr.) scores. These were compared between FaR and ORIF groups. RESULTS: Seventeen FaR patients (average age 74.5 ± 9.0 years) and 11 ORIF patients (average age 69.4 ± 9.6 years) met inclusion criteria. Mean follow-up was 26.4 months (range: 6-75.6 months). More FaR group patients were ordered immediate weight-bearing as tolerated or partial weight-bearing compared with ORIF alone (70% vs. 9.0%, P = 0.03). More patients in the FaR group had pre-existing hip osteoarthritis compared with ORIF alone (71% vs. 27%, P = 0.05). Fracture classification ( P = 0.03) and Charlson Comorbidity Index ( P = 0.02) differed between the 2 groups. There were no other differences in demographics, LOS ( P = 0.99), postoperative disposition ( P = 0.54), time to postoperative mobilization ( P = 0.38), 90-day readmission rates ( P = 0.51), operative time ( P = 0.06), radiographic union ( P = 0.35), time to union ( P = 0.63), pre- ( P = 0.32) or postoperative HOOS Jr. scores ( P = 0.80), delta HOOS Jr. scores ( P = 0.28), or reoperation rates between groups ( P = 0.15). CONCLUSIONS: FaR and ORIF seem to be sound treatment options in the management of geriatric acetabular fractures. Patients in the FaR group achieved immediate or partial weight-bearing earlier than the ORIF group; however, time to postoperative mobilization did not differ between the two groups. The remainder of acute postoperative outcomes (LOS, postoperative disposition, and 90-day readmission rates) did not differ between the two groups. LEVEL OF EVIDENCE: Therapeutic Level III.

Time to surgery and outcomes following open reduction and internal fixation of both-bone forearm fractures.

PURPOSE: To determine the effect of time to surgery on outcomes following open reduction and internal fixation (ORIF) of both-bone forearm fractures (BBFFs). METHODS: Ninety-nine patients who underwent ORIF of BBFFs in a single academic medical center over a 16-year time period were retrospectively reviewed. Demographic and clinical data including age, sex, current smoking status, time from injury to surgery (tsurg), presence of open injury, polytrauma status, and complications were obtained. Radiographs of the affected extremity were reviewed for fracture morphology, reduction quality, and time to union (or presence of nonunion). In addition to descriptive statistics, Chi-square and Wilcoxon-Mann-Whitney tests were used to compare categorical and interval, respectively, with a significance level of 0.05. RESULTS: A tsurg > 48 h was associated with increased rate of delayed unions (tsurg < 48 h: 25% vs tsurg > 48 h: 59%, p = 0.03), but not complications (tsurg < 48 h: 44% vs tsurg > 48 h: 47%, p = 0.79). Open BBFFs were not associated with increased rates of delayed unions (closed: 16% vs open: 19%, p = 0.77) or complications (closed: 42% vs open: 53%, p = 0.29). A trend toward increased time to union with tsurg > 48 h was also seen, but did not reach significance (tsurg < 48 h: 13.5 weeks vs tsurg > 48 h: 15.7 weeks, p = 0.11). CONCLUSION: A tsurg > 48 h is associated with an increased rate of delayed union, but not complications, after ORIF of BBFFs. LEVEL OF EVIDENCE: Therapeutic Level III (Retrospective Cohort).

Utility of prophylactic closed suction drainage in open reduction and internal fixation for tibial plateau fracture.

PURPOSE: The usefulness of closed suction drains (CSD) after open reduction and internal fixation (ORIF) of tibial plateau fractures is a contested topic. The purpose of this study was to examine the impact of CSD in postoperative outcomes after tibial plateau fracture. METHODS: Data were retrospectively collected from patients who underwent primary repair of closed tibial plateau fractures via an anterolateral approach between June 2021 to May 2022 at a single academic center. Fifty-six patients were included and 28 received CSDs at time of surgery. P values less than 0.05 were considered significant. RESULTS: Fifty-six patients were included. There was no significant difference in demographics, pre- and post-op hemoglobin, estimated blood loss during surgery, length of stay, postoperative MMEs and pain at 3 month follow-up, deep vein thrombosis (DVT), compartment syndrome, flexion contracture, use of incisional vac, infection rate, wound drainage, hematoma, neurologic pain, dehiscence, additional surgery, or range of motion at 3 months follow-up. We noted a significant difference in Defense and Veterans Pain Rating Scale (DVPRS) on POD1, demonstrating greater pain in those in the CSD group. CONCLUSION: Our findings suggest that the use of CSD in ORIF of tibial plateau fractures may not be of significant prophylactic benefit. CSDs in ORIF patients were associated with increased early postoperative pain and had no identifiable benefits. LEVEL OF EVIDENCE: III.

Mid-term Incidence of Tarsometatarsal Joint Arthrodesis Following Open Reduction With Internal Fixation (ORIF) of Lisfranc Injuries.

Open reduction with internal fixation (ORIF) of Lisfranc injuries are associated with an increased risk for secondary surgery including hardware removal and salvage arthrodesis. In the current literature, rates of salvage arthrodesis vary due to small sample sizes and a low incidence of Lisfranc injuries. There is little evidence to identify specific surgical and patient-related variables that may result in later arthrodesis. The purpose of this study is to determine the rate of tarsometatarsal joint arthrodesis following Lisfranc ORIF in a relatively large sample size. This retrospective review included patients who underwent ORIF for a Lisfranc injury between January 2007 and December 2012. A total of 146 patients met our criteria. Trans-articular fixation was used in 109 (74.6%) patients, 33 (22.6%) received percutaneous fixation and 4 (2.7%) extraarticular fixation. Five out of 120 (4.2%) patients required a salvage arthrodesis for post-traumatic arthritis that had a follow-up greater than 5 y but up to 10 y. The mean age of patients who underwent arthrodesis after ORIF was 24.5 ± 11.95 (16-48) y compared to 40.9 ± 15.8 (16-85) y. Patients who required an arthrodesis also had earlier hardware removal than patients who did not have an arthrodesis, 71.2 ± 28.3 (38-100) days and 131.4 ±101.2 (37-606) days, respectively. Patients who required salvage arthrodesis tended to be younger and hardware was removed earlier compared to those patients who did not require an arthrodesis. Four of the 5 patients who underwent a secondary arthrodesis had a loss of correction after hardware removal.

Indications, complications, and clinical outcomes of fixation and acute total hip arthroplasty for the treatment of acetabular fractures: A systematic review.

PURPOSE: Acetabular fracture fixation can be challenging, especially in the elderly. Open reduction and internal fixation (ORIF) alone may not allow for early weight bearing and is associated with a high rate of secondary osteoarthritis; therefore, a combined hip procedure (CHP) or ORIF with acute total hip arthroplasty, may be beneficial in this population. The objective of this study was to perform a systematic review of all reported cases of CHP. METHODS: PubMed, Embase, Scopus, and Cochrane databases were searched for studies analyzing acetabular fractures in the elderly managed with a combined hip procedure (CHP). The research was performed following the PRISMA guidelines. The included studies' methodological quality was evaluated using the MINORS score. The present study was registered on PROSPERO. RESULTS: Eleven clinical studies were included in the final analysis. The mean age was 74.4 (63.2-78) years. Low-energy trauma was the most common mechanism of injury (64%). The most prevalent fracture pattern was the anterior column and posterior hemitransverse (ACPHT) (30.6%). The Kocher-Langenbeck approach was preferred for ORIF of posterior fractures and hip arthroplasty. The ilioinguinal approach and modified Stoppa were generally used for anterior fractures. The overall complication rate was 12.2%, and hip dislocation was the most frequent cause of reoperation (4.4%). The average Harris Hip Score reported postoperatively was 81.6 points, which was considered "good." CONCLUSIONS: CHP is a safe treatment for elderly acetabular fractures with an acceptable complication and reoperation rate that results in good clinical outcomes. LEVEL OF EVIDENCE: Level of evidence IV.

A 17-Year-Old Male With Hypoxemia After Long-Bone Fracture.

CASE PRESENTATION: An otherwise healthy 17-year-old male patient presented to a periphery hospital with a compound fracture of the right distal tibia and fibula after a traumatic accident on a ski trip. He was treated empirically with IV cefazolin before undergoing open reduction with internal fixation with intramedullary nail for surgical fixation. Postoperatively, he became febrile, tachypneic, and hypoxemic, requiring up to 6 L/min supplemental oxygen by nasal prongs. He reported mild chest discomfort but denied productive cough, hemoptysis, or calf tenderness. Because of nonresolving oxygen demands, on postoperative day (POD) 4, he was transferred to a tertiary care center for further management.

Open Fixation After Preperitoneal Pelvic Packing Is Associated With a High Surgical Site Infection Rate.

OBJECTIVES: To evaluate the incidence of pelvic space surgical site infection (SSI) after preperitoneal pelvic packing (PPP) for persistent hemodynamic instability. DESIGN: Retrospective comparative study. SETTING: Urban Level 1 trauma center. PATIENTS/PARTICIPANTS: 83 patients who received PPP and 55 patients who had open reduction and internal fixation (ORIF) of the anterior pelvic ring without PPP. INTERVENTION: Operative fixation. MAIN OUTCOME MEASUREMENTS: Pelvic space SSI. RESULTS: The SSI rate in the PPP group was 31.3% (26/83) compared with 10.9% (6/55) in the control group (proportional difference 20.4%, confidence interval (CI) 6.4-32.5, P = 0.007). Patients in the PPP group (n = 43) were 1:1 propensity score matched with patients in the control group to account for differences in Injury Severity Score and American Society of Anesthesiologists score. In this matched cohort, the rate of pelvic space SSI remained higher in the PPP group compared with that in the control group (30.2% vs. 9.3%; proportional difference 20.9%, CI, 3.7-36.3; P = 0.02). On multivariate analysis of the PPP group, anterior ORIF (odds ratio 6.56, CI, 2.00-21.47, P = 0.002) was found to be independently associated with SSI. CONCLUSIONS: PPP is an independent risk factor of space SSI. The likelihood of SSI after PPP is increased with anterior ORIF. The morbidity of SSI after PPP must be weighed against the risk of exsanguination. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Supraclavicular nerve sparing versus sacrifice during open reduction internal fixation of acute midshaft clavicle fracture.

BACKGROUND: The branches of the supraclavicular nerve are often sacrificed during open reduction and internal fixation (ORIF) for clavicle fracture. No consensus exists on whether the supraclavicular nerve should be routinely identified and protected during ORIF. METHODS: We developed a simple method to make nerve sparing easier; Wide-Awake Local Anesthesia No Tourniquet (WALANT) solution is locally injected prior to the surgical incision being made. This retrospective study enrolled 340 patients and divided them into supraclavicular-nerve-sparing (n = 45) and supraclavicular-nerve-sacrifice (n = 295) groups. Surgical outcomes-including operative time, estimated blood loss, postoperative pain, union rate, time to union, functional score, paresthesia, complications, implant removal rate, and complication rate-were recorded. RESULTS: Incisional or anterior chest wall numbness and intraoperative blood loss were significantly less (p < 0.001) in the nerve-sparing group. The operative time was similar in the two groups. No significant differences were discovered in QuickDASH score, postoperative pain score, union rate, time to union, implant removal rate, complication rate, or revision rate. CONCLUSIONS: Our study demonstrated that the outcomes of supraclavicular nerve sparing during ORIF with WALANT can reduce postoperative incisional and anterior chest wall numbness and intraoperative blood loss without increasing the operative time or complication rate.

Outcome and complication comparison for intramedullary nail versus open reduction internal fixation in humeral diaphyseal fractures for 2800 matched patient pairs utilizing the Nationwide Readmissions Database.

INTRODUCTION: Open reduction internal fixation (ORIF) and intramedullary nail fixation (IMN) are the predominant repair methods for operative treatment of humeral diaphyseal fractures; however, the optimal method is not fully elucidated. The purpose of this study was to analyze whether IMN or ORIF humeral diaphyseal surgeries result in a significantly higher prevalence of adverse outcomes and whether these outcomes were age dependent. We hypothesize there is no difference in reoperation rates and complications between IMN and ORIF for humeral diaphyseal fractures. METHODS: Data collected from 2015 to 2017 from the Nationwide Readmissions Database were evaluated to compare the prevalence of six adverse outcomes: radial nerve palsy, infections, nonunion, malunion, delayed healing, and revisions. Patients treated for a primary humeral diaphyseal fracture with either IMN or ORIF were matched and compared (n = 2,804 pairs). Patients with metastatic cancer were excluded. RESULTS: Following an ORIF procedure, there was a greater odds of undergoing revision surgery (p = 0.03) or developing at least one of the complications of interest (p = 0.03). In the age-stratified analysis, no significant differences were identified in the prevalence of adverse outcomes between the IMN and ORIF cohorts in the 0-19, 20-39, and 40-59 age groups. Patients who were 60 + had 1.89 times the odds of experiencing at least one complication and 2.04 times the odds of undergoing a revision after an ORIF procedure versus an IMN procedure (p = 0.03 for both). DISCUSSION: IMN and ORIF for humeral diaphyseal fractures are comparable in regard to complications revision rates in patients under the age of 60. Meanwhile, patients 60 + years show a statistically significant increase in the odds of undergoing revision surgery or experiencing complications following an ORIF. Since IMN appears to be more beneficial to older patients, being 60 + years old should be considered when determining fracture repair techniques for patients presenting with primary humeral diaphyseal fractures.

Traumatic Obturator Hip Dislocation in a 9-Year-Old Girl: A Case Report.

CASE: We present a case of traumatic anterior obturator hip dislocation in a pediatric patient with a focus on acute management of this injury. The orthopaedic team successfully performed closed reduction of this injury on an emergent basis, and the patient had minimal issues with ambulation and pain at subsequent follow-up. CONCLUSION: Pediatric traumatic hip dislocations are rare injuries with potentially devastating sequelae, particularly if diagnosis and treatment are delayed. Proper technique during closed reduction is essential. Be prepared for potential emergent open reduction. Two years of postinjury follow-up is recommended to monitor for signs of femoral head osteonecrosis.

Incidence and risk factors for complex regional pain syndrome in radius fractures: meta-analysis.

PURPOSE: This meta-analysis aimed to evaluate the incidence and risk factors for complex regional pain syndrome (CRPS) in radius fractures. METHODS: The meta-analysis was performed using the PubMed, Embase, Scopus, and Cochrane Collaboration Library databases. Studies focusing on patients with conservative or surgically treated radius fractures leading to CRPS were included. A control group consisting of patients with radius fractures and no CRPS (-) was included. The outcome measures were incidence and risk factors. Comparative studies were also included. Data were combined using Review Manager 5.4. RESULTS: Out of 610 studies, nine studies were included. The incidence of CRPS after radius fractures ranged from 0.19 to 13.63% (95% CI: 11.12-16.15%). Open fractures, high-energy mechanisms in radial head fractures, and associations with ulnar fractures were risk factors for CRPS [(RR: 0.98; 95% CI: 0.97-1.00), (RR: 0.18; 95% CI: 0.07-0.47), and (RR: 1.25; 95% CI: 1.17-1.35), respectively]. Other risk factors were female sex and high body mass index [(RR: 1.20; 95% CI: 1.05-1.37) and (MD: 1.17; 95% CI: 0.45-1.88)]. Psychiatric factors also increased the incidence of CRPS (RR: 2.04; 95% CI: 1.83-2.28). On the other hand, the type of surgery (external fixation or open reduction and internal fixation) and manipulations; associated comorbidities (diabetes and hypertension) together with tobacco and alcohol abuse; marital status, educational level, employment status, and socioeconomic status were not risk factors (p > 0.05). CONCLUSION: The incidence of CRPS in radius fractures was 13.63%. Fractures with greater complexity or greater associated tissue damage, female sex, high BMI, and psychiatric disorders were risk factors for the development of CRPS. LEVEL OF EVIDENCE: Meta-analysis of cohort and case series studies; II.

Impact of patient-related factors on complications when treating mandibular fractures by load-sharing and load-bearing osteosynthesis.

The decision about the choice of load-sharing (LS) or load-bearing (LB) osteosynthesis is determined by an interplay of fracture-related and patient-related factors. In some situations a similar fracture in two different patients may be treated successfully by either of these methods. Our aim was to identify preoperative patient-related factors that may assist in deciding which form of osteosynthesis is employed. All adult patients who underwent open reduction and internal fixation of mandibular fractures (excluding condyle) between 1 October 2018 and 1 June 2021 were retrospectively identified. The odds of developing postoperative complications and requiring a return to theatre (RTT) were calculated for each method of fixation together with the following patient factors: smoking, excess alcohol, substance misuse, and severe mental health issues. Of 337 fractures treated using LS principles, 27 (8%) developed complications, of which 20 (6%) required a RTT for repeat osteosynthesis. Of 74 fractures treated using LB principles, seven (10%) developed complications and two (3%) required a RTT for repeat osteosynthesis. The only patient factor that had statistically significant increased odds of a complication requiring RTT was LS osteosynthesis in patients who admitted drinking excess alcohol (OR = 7.83, p = 0.00, 95% CI = 3.13 to 19.60). Complications when treating mandibular fractures are rarely reported in the literature, and lack standardisation in their clinical significance. Figures generally represent overall numbers of patients, whereas the number of individual fractures treated is more accurate. In our study complications occurred in 8% of treated fractures and 10% of patients. The RTT rate was 7% of patients, which compares favourably with a recently stated standard of 10% of patients, as suggested by the Getting it Right First Time (GIRFT) report.

Risks of Immunosuppressive Therapy in Patients Undergoing Open Reduction Internal Fixation for Ankle Fractures.

Chronic steroid and immunosuppressant use have been shown to increase the risk for postoperative complications in orthopedic surgery. Further understanding of the risks of immunosuppression is necessary to aid in risk stratification and patient counseling. However, these risks have not yet been explored in ankle fracture patients. Thus, the purpose of this study is to determine whether patients taking immunosuppressives are at an increased risk for morbidity and mortality following open reduction and internal fixation (ORIF) of ankle fractures. Patients undergoing operative treatment for ankle fractures from 2006 to 2018 were identified in the National Surgical Quality Improvement Program database. Patients were categorized based on their use of immunosuppressive medications. Postoperative outcomes assessed included superficial surgical site infections, deep surgical site infections, organ space infections, wound dehiscence, pneumonia, unplanned intubation, pulmonary embolism, urinary tract infection, renal failure, blood transfusion requirement, deep vein thrombosis, sepsis, cardiac arrest, extended length of hospital stay, readmission, reoperation, and mortality. Univariate and multivariate analyses were performed. In total, 10,331 patients underwent operative treatment for ankle fracture. Total 10,153 patients (98.3%) were not taking immunosuppressants and 178 (1.7%) were taking these medications. In multivariate analysis, patients taking immunosuppressants were at increased risk of pulmonary embolism (odds ratio [OR] 4.382; p = .041) and hospital readmission (OR 2.131; p = .021). Use of immunosuppressive medications is an independent risk factor for pulmonary embolism and readmission following ORIF for ankle fractures. Notably, no association with wound complications, infections, or sepsis was identified.

Clinical Characteristics and Treatment Patterns of Open Hand Fractures in the Pediatric Population.

BACKGROUND: Open hand fractures are one of the most common injuries in the pediatric population. These injuries are at higher risk of infection, especially in cases of frank contamination. Several studies on adult hand fractures are available in the literature; however, pediatric open hand fractures have yet to be extensively studied. This study aimed to define pediatric open hand fracture's demographics, clinical characteristics, and treatment patterns. METHODS: Using the Protected Health Information database, pediatric patients (<18 y old) with the diagnosis of open hand fracture from June 2016 to June 2018 were extracted. Demographic, treatment, and follow-up data were collected. Clinical outcomes included readmission and postoperative infection rates. RESULTS: There were a total of 4516 patients who met the inclusion criteria; the median age was 7 years (interquartile range: 3 to 11); 60% males; 60% white. Displaced fractures occurred in 74% of patients, with the right hand (52%) and middle finger (27%) predominance. The most common mechanism of injury was a crushing injury in-between objects (56%). Associated nerve injury occurred in 78 patients (4%) and vascular injury in 43 patients (2%). Open reduction and internal fixation were performed in 30% of patients. Cephalosporins were the most commonly prescribed antibiotics (73%), followed by aminopenicillins (7%). Nine patients had complications related to surgical intervention (0.2%), and postoperative infection occurred in 44 patients (1%). CONCLUSIONS: Pediatric open hand fractures most often occur during childhood and more frequently in males. These fractures tend to be more distal and displaced; reduction and fixation are required in one-third of the cases. Despite the absence of treatment guidelines and variability, this injury exhibits low complication rates. LEVEL OF EVIDENCE: Level III, retrospective study.

Comparison of clinical and radiographic outcomes of arthroscopic-assisted percutaneous fixation versus open reduction internal fixation of lateral tibial plateau fractures.

PURPOSE: Treatment for tibial plateau fractures continues to evolve but maintains primary objectives of anatomic reduction of the joint line and a rapid recovery course. Arthroscopic-assisted percutaneous fixation (AAPF) has been introduced as an alternative to traditional open reduction internal fixation (ORIF). The purpose of the study is to compare clinical and radiographic outcomes in patients with low-energy Schatzker type I-III tibial plateau fractures treated with AAPF versus ORIF. METHODS: A retrospective chart review was performed at a level 1 trauma centre to compare outcomes of 120 patients (57 AAPF, 63 ORIF) with low-energy lateral Schatzker type I-III tibial plateau fractures who underwent tibial plateau fixation between 2009 and 2018. Demographic information, injury characteristics, and surgical treatment were recorded. The main outcome measurements included reduction step-off, joint space narrowing, time to weight bearing, and implant removal. RESULTS: There was no difference in age, gender distribution, BMI, ASA, Schatzker classification distribution, initial displacement, blood loss, and reduction step-off between the two groups (p > 0.05). Shorter tourniquet time (74.1 ± 21.7 vs 100.0 ± 21.0 min; p < 0.001), shorter time to full weight bearing (47.8 ± 15.2 vs. 69.1 ± 17.2 days; p < 0.001), and lower rate of joint space narrowing (3.5% vs. 28.6% with more than 1 mm, p < 0.001) were associated with the AAPF cohort, with no difference in pain, knee range of motion, or implant removal rate between the two cohorts. CONCLUSION: AAPF may be a viable alternative to ORIF for the management of low-energy tibial plateau fractures with outcomes not inferior compared to the traditional ORIF method.

Acute versus delayed total hip arthroplasty after acetabular fracture fixation: a systematic review and meta-analysis.

BACKGROUND: Post-traumatic osteoarthritis (PTOA) is a disabling complication of open reduction and internal fixation (ORIF) for acetabular fractures. There is a trend towards acute total hip arthroplasty (THA), 'fix-and-replace', in patients considered to have a poor prognosis and likelihood of PTOA. Controversy remains between early fix-and-replace, versus delayed THA as required after initial ORIF. This systematic review included studies comparing functional and clinical outcomes between acute versus delayed THA after displaced acetabular fractures. METHODS: Comprehensive searches following the PRISMA guideline were performed on six databases for articles in English published anytime up to 29 March 2021. Two authors screened articles and discrepancies were resolved by consensus. Patient demographics, fracture classification, functional and clinical outcomes were compiled and analysed. RESULTS: The search yielded 2770 unique studies, of which five retrospective studies were identified with a total of 255 patients. Of them, 138 (54.1%) were treated with acute and 117 (45.9%) treated with delayed THA. Delayed THA group represented a younger cohort compared to the acute group (mean age, 64.3 vs 73.3). The mean follow-up time for the acute and delayed group was 23 and 50 months, respectively. There was no difference in functional outcomes between the two study groups. Complication and mortality rates were comparable. Delayed THA had a higher revision rate compared to the acute group (17.1 vs 4.3%; p = 0.002). CONCLUSION: Fix-and-replace had functional outcomes and complication rates similar to ORIF and delayed THA, but lower revision rates. Although the quality of studies was mixed, sufficient equipoise now exists to justify randomised studies in this area. PROSPERO registration: CRD42021235730.

What Factors Are Associated With Delayed Wound Closure in Open Reduction and Internal Fixation of Adult Both-bone Forearm Fractures?

BACKGROUND: Delayed wound closure is often used after open reduction and internal fixation (ORIF) of both-bone forearm fractures to reduce the risk of skin necrosis and subsequent infection caused by excessive swelling. However, no studies we are aware of have evaluated factors associated with the use of delayed wound closure after ORIF. QUESTIONS/PURPOSES: (1) What proportion of patients undergo delayed wound closure after ORIF of adult both-bone forearm fractures? (2) What factors are associated with delayed wound closure? METHODS: The medical records of all patients who underwent ORIF with plate fixation for both-bone fractures by the adult orthopaedic trauma service at our institution were considered potentially eligible for analysis. Between January 2010 and April 2022, we treated 74 patients with ORIF for both-bone forearm fractures. Patients were excluded if they had fractures that were fixed more than 2 weeks from injury (six patients), if their fracture was treated with an intramedullary nail (one patient), or if the patient experienced compartment syndrome preoperatively (one patient). No patients with Gustilo-Anderson Type IIIB and C open fractures were included. Based on these criteria, 89% (66 of 74) of the patients were eligible. No further patients were excluded for loss of follow-up because the primary endpoint was the use of delayed wound closure, which was performed at the time of ORIF. However, one further patient was excluded for having bilateral forearm fractures to ensure that each patient had a single fracture for statistical analysis. Thus, 88% (65 of 74) of patients were included in the analysis. These patients were captured by an electronic medical record search of CPT code 25575. The mean ± SD age was 34 ± 15 years and mean BMI was 28 ± 7 kg/m 2 . The mean follow-up duration was 4 ± 5 months. The primary endpoint was the use of delayed wound closure, which was determined at the time of definitive fixation if tension-free closure could not be achieved. All surgeons used a volar Henry or modified Henry approach and a dorsal subcutaneous approach to the ulna for ORIF. Univariate logistic regression was used to identify which factors might be associated with delayed wound closure. A multivariable logistic regression analysis was then performed for male gender, open fractures, age, and BMI. RESULTS: Twenty percent (13 of 65) of patients underwent delayed wound closure, 18% (12 of 65) of which occurred in patients who had high-energy injuries and 14% (nine of 65) in patients who had open fractures. Being a man (adjusted odds ratio 9.9 [95% confidence interval 1 to 87]; p = 0.04) was independently associated with delayed wound closure, after adjusting for open fractures, age, and BMI. CONCLUSION: One of five patients had delayed wound closure after ORIF of both-bone forearm fractures. Being a man was independently associated with greater odds of delayed wound closure. Surgeons should counsel all patients with these fractures about the possibility of delayed wound closure, with particular attention to men with high-energy and open fractures. Future larger-scale studies are necessary to confirm which factors are associated with the use of delayed wound closure in ORIF of both-bone fractures and its effects on fracture healing. LEVEL OF EVIDENCE: Level III, therapeutic study.

Proximal Plate Migration After Internal Fixation of a Pediatric Distal Radius Fracture.

We present a case of a 26-year-old right-hand-dominant male stage manager who underwent open reduction internal fixation of right open both-bone forearm fractures at the age of 13. The patient presented 13 years and 8 months later with proximal hardware migration, soft tissue erosion, and subsequent hardware exposure. The patient underwent hardware removal with resolution of pain and improvement in range of motion. To the best of our knowledge, this complication has not been published before.
