ABSTRACT
CASE: We present a 17-year-old male patient with an initially missed posterior sternoclavicular fracture dislocation who presented with symptoms related to thrombotic emboli arising from a pseudoaneurysm. He was treated 6 weeks after injury with a figure-of-eight tendon allograft repair with good clinical outcomes. CONCLUSION: This is a unique presentation that highlights the significant risk of a missed diagnosis, life-threatening complications that may ensue, and biomechanically superior surgical intervention.

Clavicle fracture is a common orthopedic injury, accounting for approximately 2.6%-4% of all adult skeletal fractures. In 2023, the American Academy of Orthopaedic Surgeons (AAOS) developed evidence-based treatment guidelines for clavicle fractures, which include 4 recommendations and 10 options. This article, based on a thorough review of the guidelines, discusses the clinical treatment of clavicle fractures, aiming to share advancements and the latest diagnostic and therapeutic considerations with orthopedic colleagues to enhance treatment outcomes.

Objective: To explore the effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures. Methods: Between January 2022 and February 2023, 10 patients with Tile type B pelvic fractures were admitted. There were 6 males and 4 females with an average age of 45.5 years (range, 30-71 years). The fractures were caused by traffic accident in 5 cases, bruising by heavy object in 3 cases, and falling from height in 2 cases. The interval between injury and operation ranged from 4-13 days (mean, 6.8 days). There were 2 cases of Tile type B1 fractures, 1 case of Tile type B2 fracture, and 7 cases of Tile type B3 fractures. After closed reduction under assistance of reduction robot, the anterior ring was fixed with percutaneous screws with or without internal fixator, and the posterior ring was fixed with sacroiliac joint screws under assistance of navigation robot. The time of fracture reduction assisted by the reduction robot was recorded and the quality of fracture reduction was evaluated according to the Matta scoring criteria. The operation time, intraoperative fluoroscopy frequency and time, intraoperative bleeding volume, and incidence of complications were also recorded. During follow-up, the X-ray film of pelvis was taken to review the fracture healing, and the Majeed score was used to evaluate hip joint function. Results: The time of fracture reduction was 42-62 minutes (mean, 52.3 minutes). The quality of fracture reduction according to the Matta scoring criteria was rated as excellent in 4 cases, good in 5 cases, and poor in 1 case, with excellent and good rate of 90%. The operation time was 180-235 minutes (mean, 215.5 minutes). Intraoperative fluoroscopy was performed 18-66 times (mean, 31.8 times). Intraoperative fluoroscopy time was 16-59 seconds (mean, 28.6 seconds). The intraoperative bleeding volume was 50-200 mL (range, 110.0 mL). No significant vascular or nerve injury occurred during operation. All patients were followed up 13-18 months (mean, 16 months). X-ray films showed that all fractures healed with the healing time of 11-14 weeks (mean, 12.3 weeks). One case of ectopic ossification occurred during follow-up. At last follow-up, the Majeed score was 70-92 (mean, 72.7), and the hip joint function was rated as excellent in 2 cases and good in 8 cases, with the excellent and good rate of 100%. Conclusion: The reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures has the characteristics of intelligence, high safety, convenient operation, and minimally invasive treatment, which can achieve reliable effectiveness.

Objective: To explore effectiveness of minimally invasive internal fixation with locking plates for mid-shaft clavicle fractures. Methods: Between October 2022 and August 2023, 28 patients with mid-shaft clavicle fractures were treated by minimally invasive internal fixation with locking plates. There were 10 males and 18 females with a mean age of 46.2 years (range, 18-74 years). The fractures were caused by traffic accident in 16 patients, sports-related injury in 7 patients, and other injuries in 5 patients. According to Robinson classiï¬cation, the fractures were classified as type 2A1 in 1 case, type 2A2 in 6 cases, type 2B1 in 15 cases, and type 2B2 in 6 cases. The interval between fracture and operation ranged from 5 hours to 21 days (median, 1.0 days). The pain visual analogue scale (VAS) score was 8.1±1.6. The VAS score at 3 days after operation and the occurrence of complications after operation were recorded. During follow-up, X-ray films were re-examined to observe the healing of the fracture; the shoulder joint function was evaluated according to the Constant-Murley score at 6 months, and the length of the incision scar (total length of the distal and proximal incisions) was measured. Results: All operations were successfully completed without any subclavian vascular or nerve damage. All incisions healed by first intention. The VAS score was 1.2±0.7 at 3 days after operation, and there was a significant difference in VAS score between pre- and post-operation ( t=8.704ï¼ P<0.001). At 1 week after operation, the patient's shoulder was basically painless, and they resumed normal life. All patients were followed up 12-20 months (mean, 13.3 months). X-ray films showed that the bone callus began to form at 2-4 months after operation (mean, 2.7 months). There was no delayed healing or non healing of the fracture, and no loosening or fracture of the internal fixators during follow-up. At 6 months after operation, the mean total incision length was 1.5 cm (range, 1.1-1.8 cm); no patient complained of numbness or paresthesia on subclavicular region or anterior chest wall. The Constant-Murley score of shoulder joint function was 93-100 (mean, 97.6). Conclusion: Minimally invasive internal fixation with locking plates is a good surgical method for treating mid-shaft clavicle fractures, with simple operation, minimal trauma, good postoperative results, and high satisfaction.

Objective: To compare the effectiveness of open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation for bony mallet fingers. Methods: The clinical data of 68 patients with bony mallet finger who admitted between May 2019 and June 2022 were retrospectively analyzed. Among them, 33 cases were in the open group (treated with open reduction and hook plate fixation) and 35 cases were in the closed group (treated with closed indirect reduction and dorsal extension blocking Kirschner wire fixation). There was no significant difference between the two groups in terms of gender, age, the affected side, the affected finger, cause of injury, time from injury to operation, and Wehbé-Schneider classification ( P>0.05). The operation time, intraoperative fluoroscopy frequency, fracture healing time, time of returning to work, and postoperative complications were recorded and compared between the two groups. At 12 months after operation, visual analogue scale (VAS) score was used to assess the pain of the injured finger, active flexion range of motion and extension deficit of the distal interphalangeal joint (DIP) were measured by goniometer, and the effectiveness was assessed by Crawford criteria. Results: All patients in the two groups were followed up 12-26 months, with an average of 15 months. There was no significant difference in the follow-up time between the closed group and the open group ( P>0.05). The operation time in the closed group was shorter than that in the open group, and the intraoperative fluoroscopy times, the fracture healing time, and the time of returning to work in the closed group were more than those in the open group, and the differences were significant ( P<0.05). In the closed group, there were 5 cases of pinning tract infection and 3 cases of small area pressure ulcer skin necrosis on the dorsal side of the finger, which were cured after intensive nursing and dressing change. Local nail depression deformity occurred in 7 cases in the open group, and the deformity disappeared after removal of plate. The incisions of the other patients healed uneventfully without complications such as infection, skin necrosis, exposure of the internal fixation, or nail deformity. There was no significant difference in the incidence of skin necrosis between the two groups ( P>0.05), but the differences in the incidence of infection and nail deformity between the two groups were significant ( P<0.05). There was no significant difference in VAS score, DIP active flexion range of motion, DIP extension deficiency, or Crawford criteria evaluation between the two groups at 12 months after operation ( P>0.05). At last follow-up, there was no DIP osteoarthritis and joint degeneration in both groups. Conclusion: Open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation have their own advantages and disadvantages, but both of them have good results in the treatment of bony mallet fingers. Open reduction and hook plate fixation is recommended for young patients with bony mallet fingers who are eager to return to work.

Checkrein deformity of the hallux is commonly characterized by rigid flexion of the interphalangeal joint in ankle dorsiflexion but with flexibility in ankle plantarflexion which can be named as flexion checkrein deformity and as rare condition, extension checkrein deformity, characterized by rigid extension of the first metatarsophalangeal joint in ankle plantarflexion and flexibility in ankle dorsiflexion, has been reported. However, there has not reported coexistence of flexion and extension checkrein deformity. The patient, a 27-year-old male, was referred to our department 3 years after tibial and fibular fractures which was treated by open reduction and internal fixation at a previous hospital. His chief complaint was pain and impaired plantarflexion of the affected great toe. The diagnosis was double checkrein deformity characterized by simultaneous rigidity in both flexion and extension of the hallux due to the adhesion of the flexor hallucis longus (FHL) muscle and the extensor hallucis longus (EHL) tendon after a fracture. Surgical intervention was performed, which involved the transection of the FHL tendon using hindfoot endoscopy and transfer of the EHL to the extensor digitorum longus, resulting in a successful outcome with no postoperative complications. The patient demonstrated a favorable prognosis 2 years after the procedure. This report represents the first documented case of double checkrein deformity and underscores the importance of considering this condition and the potential advantages of surgical intervention.

PURPOSE: Analyzing the correlation between patients' basic information, three-dimensional parameters after calcaneal fractures, and the prognosis of calcaneal fractures. METHODS: A retrospective analysis was conducted on 43 patients with calcaneal fractures who underwent surgical treatment in the Foot and Ankle Surgery, Xi'an Honghui Hospital, from September 2019 to August 2022. Patient demographics including gender and age were collected, as well as the preoperative posterior articular surface collapse area, number of fracture fragments, length, width, height, and volume of the calcaneus obtained from preoperative three-dimensional imaging. Patients were followed up for VAS, AOFAS, and SF-36 scores. Correlation analysis was performed on the obtained data. RESULTS: All 43 included patients received complete follow-up, including 40 males and 3 females, with an average follow-up time of 35.37 ± 10.73 months, and an average age of 43.98 ± 12.08 years. All patients' VAS, AOFAS, and SF-36 scores at the last follow-up showed no correlation with patient age, gender, or the area of posterior articular collapse, number of fracture fragments, length, width, height, or volume of the calcaneus. CONCLUSIONS: The prognosis of calcaneal fractures is unrelated to three-dimensional factors such as patient age, gender, length, width, height, volume of the calcaneus, area of the posterior joint, and number of fracture fragments.

BACKGROUND: A coracoid process fracture combined with an acromioclavicular (AC) joint dislocation is an uncommon injury that typically causes significant pain and limits shoulder movement. Open reduction and internal fixation have been the traditional treatment approach. However, arthroscopic techniques are emerging as a promising alternative for managing these injuries. CASE REPRESENTATION: A 35-year-old woman presented with right shoulder pain following an accidental fall. Imaging studies revealed a coracoid process fracture along with an AC joint dislocation. The fracture was classified as an Eyres Type IIIA, which warranted surgical intervention. Our team performed arthroscopic coracoid fracture reduction and internal fixation surgery, as well as AC joint dislocation repair using Kirschner wires. Six months after surgery, the patient demonstrated a satisfactory functional outcome with complete bone healing. CONCLUSION: This case report highlights the potential of arthroscopic reduction and fixation as a novel treatment option for fractures of the coracoid base.

The objective of this descriptive cross-sectional study was to assess the functional outcomes of adolescents who had undergone internal fixation for patellar post-traumatic OCD fracture from 2019-2021. The injury mechanism was divided into two categories: a) torsional mechanism and b) direct contact injury. All candidates underwent X-ray and MRI/CT scan prior to the surgery to confirm the diagnosis. Operative treatment was open reduction and internal fixation (ORIF) of osteochondral fragment using headless screws. All patients were assessed pre-operatively with knee-ROM/IKDC (International Knee Documentation committee) score and satisfaction score, and postoperatively at one year follow-up. Fourteen patients were selected, with the mean age of 16.1±3.2 years. On one-year follow-up, no difference was noted in ROM when compared to the unaffected limb. The mean satisfaction score was 86±6.3 %. The mean pre-operative-IKDC score was 47.6±5.8 out of 100, whereas on one-year follow-up it was 88.6±2.2 which was statistically significant (p<0.05). Excellent outcomes can be achieved with headless screws for urgent ORIF (next elective list) of the osteochondral fragment.

OBJECTIVES: To identify the infection rate in patients with combined pelvic ring and bladder injuries. Secondary aims included identifying treatment and injury factors associated with infection. DESIGN: Retrospective review. SETTING: Single Level I Tertiary Academic Center. PATIENTS SELECTION CRITERIA: All patients over a 12-year period with combined pelvic ring and bladder injuries were evaluated. Exclusion criteria were nonoperative management of the pelvic ring, isolated posterior fixation, and follow-up <90 days. OUTCOME MEASURE AND COMPARISONS: Primary outcome measured was deep infection of the anterior pelvis requiring surgical irrigation and debridement. RESULTS: In total, 106 patients with anterior stabilization of the pelvis in the setting of a bladder injury were included. Seven patients (6.6%) developed a deep infection and required surgical debridement within 90 days. Patients undergoing open reduction and internal fixation with plating of the anterior pelvis and acute concomitant bladder repair had an infection rate of 2.2% (1/43). Patients undergoing closed reduction and anterior fixation with either external fixation or percutaneous rami screw after bladder repair had an infection rate of 17.6% (3/17). There was a higher infection rate among patients with combined intraperitoneal (IP) and extraperitoneal (EP) bladder injuries (23%) when compared with those with isolated EP (3.8%) or IP (9.1%) bladder injuries (P = 0.029). CONCLUSIONS: Acute open reduction and internal fixation of the anterior pelvis in patients with combined pelvic ring and bladder injuries has a low infection rate. Patients with combined IP and EP bladder injuries are at increased risk of infection compared with those with isolated IP and EP injuries. LEVEL OF EVIDENCE: Prognostic Level III.

OBJECTIVES: To identify factors that contribute to iatrogenic sciatic nerve palsy during acetabular surgery through a Kocher-Langenbeck approach and to evaluate if variation among individual surgeons exists. DESIGN: Retrospective cohort. SETTING: Level I trauma center. PATIENT SELECTION CRITERIA: Adults undergoing fixation of acetabular fractures (AO/OTA 62) through a posterior approach by 9 orthopaedic traumatologists between November 2010 and November 2022. OUTCOME MEASURES AND COMPARISONS: The prevalence of iatrogenic sciatic nerve palsy and comparison of the prevalence and risk of palsy between prone and lateral positions before and after adjusting for individual surgeon and the presence of transverse fracture patterns in logistic regression. Comparison of the prevalence of palsy between high-volume (>1 patient/month) and low-volume surgeons. RESULTS: A total of 644 acetabular fractures repaired through a posterior approach were included (median age 39 years, 72% male). Twenty of 644 surgeries (3.1%) resulted in iatrogenic sciatic nerve palsy with no significant difference between the prone (3.1%, 95% confidence interval [CI], 1.9%-4.9%) and lateral (3.3%, 95% CI, 1.3%-8.1%) positions (P = 0.64). Logistic regression adjusting for surgeon and transverse fracture pattern demonstrated no significant effect for positions (odds ratio 1.0, 95% CI, 0.3-3.9). Transverse fracture pattern was associated with increased palsy risk (odds ratio 3.0, 95% CI, 1.1-7.9). Individual surgeon was significantly associated with iatrogenic palsy (P < 0.02). CONCLUSIONS: Surgeon and the presence of a transverse fracture line predicted iatrogenic nerve palsy after a posterior approach to the acetabulum in this single-center cohort. Surgeons should perform the Kocher-Langenbeck approach for acetabular fixation in the position they deem most appropriate, as the position was not associated with the rate of iatrogenic palsy in this series.

OBJECTIVES: To determine the effect of obesity on systemic complications after operative pelvic ring injuries. DESIGN: Retrospective cohort study. SETTING: Single level 1 trauma center. PATIENT SELECTION CRITERIA: All patients at a level 1 trauma center who underwent operative fixation of a pelvic ring injury from 2015 to 2022 were included. Patients were grouped based on body mass index (BMI) into 4 categories (normal = BMI <25, overweight = BMI 25-30, obese = BMI 30-40, and morbidly obese BMI >40). OUTCOME MEASURES AND COMPARISONS: Systemic complications including acute respiratory distress syndrome, pneumonia, sepsis, deep venous thrombosis (DVT), pulmonary embolism, ileus, acute kidney injury (AKI), myocardial infarction, and mortality were recorded. Patients who developed a complication were compared with those who did not regarding demographic and clinical parameters to determine risk factors for each complication. RESULTS: A total of 1056 patients underwent pelvic ring fixation including 388 normal BMI, 267 overweight, 289 obese, and 112 morbidly obese patients. The average age of all patients was 36.9 years, with a range from 16 to 85 years. Overall, 631 patients (59.8%) were male. The overall complication and mortality rates were 23.2% and 1.4%, respectively. BMI was a significant independent risk factor for all-cause complication with an odds ratio of 1.67 for overweight, 2.30 for obese, and 2.45 for morbidly obese patients. The risk of DVT and AKI was also significantly increased with every weight class above normal with ORs of 5.06 and 3.02, respectively, for morbidly obese patients (BMI >40). CONCLUSIONS: This study demonstrated that among patients undergoing pelvic ring fixation, higher BMI was associated with increased risks of overall complication, specifically DVT and AKI. As the prevalence of obesity continues to increase in the population, surgeons should be cognizant that these patients may be at higher risk of certain postoperative complications during the initial trauma admission.

OBJECTIVES: To report on adverse events during magnetic resonance imaging (MRI) in patients with external fixators. METHODS: . DESIGN: Retrospective case series. SETTING: Two Level 1 trauma centers. PATIENT SELECTION CRITERIA: Patients with external fixators on the appendicular skeleton or pelvis undergoing MRI between January 2005 and September 2023. OUTCOME MEASURES AND COMPARISONS: Adverse events, defined as any undesirable event associated with the external fixator being inside or outside the MRI bore during imaging, including (subjective) heating, displacement or pullout of the external fixator, or early MRI termination for any reason. RESULTS: A total of 97 patients with 110 external fixators underwent at least one MRI scan with an external fixator inside or outside of the MRI bore. The median age was 51 years (interquartile range: 39-63) and 56 (58%) were male. The most common external fixator locations were the ankle (24%), knee (21%), femur (21%), and pelvis (19%). The median duration of the MRI was 40 minutes (interquartile range: 26-58), 86% was performed using 1.5-Tesla MRI, and 14% was performed using 3.0-Tesla MRI. Ninety-five percent of MRI was performed for the cervical spine/head. Two MRI scans (1.6%), one of the shoulder and one of the head and cervical spine, with the external fixator outside of the bore were terminated early because of patient discomfort. There were no documented events of displacement or pullout of the external fixator. CONCLUSIONS: These findings suggest that MRI scans of the (cervical) spine and head can be safely obtained in patients with external fixators on the appendicular skeleton or pelvis. Given the low numbers of MRI scans performed with the external fixator inside the bore, additional studies are necessitated to determine the safety of this procedure. The results from this study can aid orthopaedic surgeons, radiologists, and other stakeholders in developing local institutional guidelines on MRI scanning with external fixators in situ.

OBJECTIVE: Evaluation of the clinical efficacy of f trochanteric flip osteotomy combined with Kocher-Langenbeck approach for high acetabular posterior wall fracture. METHODS: Between January 2020 and December 2022, 20 patients with high acetabular posterior wall fractures were retrospectively analyzed, including 12 males and 8 females, aged 18 to 75 years old. They were divided into two groups according to the different surgical methods. Ten patients were treated with greater trochanteric osteotomy combined with Kocher-Langenbeck approach as the observation group, including 5 males and 5 females, aged from 18 to 75 years old. Ten patients were treated with Kocher-Langenbeck approach alone as the control group, including 7 males and 3 females, aged from 18 to 71 years old. Matta reduction criteria were used to evaluate the reduction quality of the two groups, and Harris score was used to compare the hip function of the two groups at the latest follow-up. The operation time, blood loss and postoperative complications of the two groups were analyzed. RESULTS: All patients were followed up for 10 to 24 months. According to the Matta fracture reduction quality evaluation criteria, the observation group achieved anatomical reduction in 6 cases, satisfactory reduction in 3 cases, and unsatisfactory reduction in 1 case, while the control group only achieved anatomical reduction in 3 cases, satisfactory reduction in 3 cases, and unsatisfactory reduction in 4 cases. At the final follow-up, the Harris hip score ranged from 71.4 to 96.6 in the observation group and 65.3 to 94.5 in the control group. According to the results of Harris score. The hip joint function of the observation group was excellent in 6 cases, good in 3 cases, and fair in 1 case. The hip joint function of the control group was excellent in 2 cases, good in 3 cases, fair in 3 cases, and poor in 2 cases. In the observation group, the intraoperative blood loss ranged from 300 to 700 ml, and the operation duration ranged from 120 to 180 min;in the control group, the intraoperative blood loss ranged from 300 to 650 ml, and the operation duration ranged from 100 to 180 min. Complications in the observation group included 1 case of traumatic arthritis and 1 case of heterotopic ossification, while complications in the control group included 3 cases of traumatic arthritis, 3 cases of heterotopic ossification and 1 case of hip abduction weakness. CONCLUSION: Trochanteric flip osteotomy combined with the Kocher-Langenbeck approach significantly improved anatomical fracture reduction rates, enhanced excellent and good hip joint function outcomes, and reduced surgical complication incidence compared to the Kocher-Langenbeck approach alone. Clinical application of this combined approach is promising, although larger studies are needed for further validation.

BACKGROUND: The Internal Fixator (INFIX) is a popular method, known for its minimal invasiveness and short operation time, for treating anterior pelvic ring fractures. Studies have shown that postoperative complications may occur, including anterolateral femoral cutaneous nerve injury, the femoral nerve paralysis, and delayed fracture healing. These complications are believed to be related to surgical stimulation, an excessively long lateral end of the connecting rod, a small distance between the screw and bone surface, insufficient pre-bending of the connecting rod, and difficulties in fracture reduction. CASE PRESENTATION: We report two unique cases of lower abdominal pseudocyst complicated with suspected infection after INFIX treatment of pelvic fractures at our trauma center. Following surgical removal of the internal fixation, resolution of the cysts was observed in both patients, and subsequent postoperative follow-up revealed the absence of any residual sequelae. These cases have not been reported in previous literature reviews. DISCUSSION: The lower abdominal cysts, potentially arising from the dead space created during intraoperative placement of the INFIX rod, may increase infection risk. The etiology remains uncertain, despite the presence of abnormal inflammation markers in both cases, and staphylococcus aureus found in one. These cysts were confined to the lower abdomen, not involving the internal fixation, and hence, only the INFIX was removed. Postoperative oral cefazolin treatment was successful, with resolved pseudocysts and no subsequent discomfort. CONCLUSION: We report two unprecedented cases of post-INFIX abdominal cysts, with a suspected link to intraoperative dead space. Despite uncertain etiology, successful management involved INFIX removal and oral cefixime therapy. These findings necessitate further exploration into the causes and management of such complications.

BACKGROUND: Imaging techniques such as X-rays and 3D Computed Tomography (CT) are used to diagnose and evaluate a patient's shoulder before and after surgery. Identifying the kind, location, and severity of a shoulder fracture helps surgeons choose the right treatment and surgery. OBJECTIVES: The study examines the effectiveness of small incision reduction and superior closure pinning in treating Ideberg type III glenoid fractures identified by X-ray and CT scans. MATERIALS AND METHODS: From October 2017 to June 2022, 40 patients with Ideberg type III glenoid fractures underwent mini-incision reduction and superior closed pinning fixation using the Anterior (AA) and Posterior (PA) approaches. Pre- and post-surgery shoulder scores and imaging data were analyzed. Outpatient review and shoulder anteroposterior radiographs were collected at 1, 3, 6, and 12 months after surgery. We assessed shoulder joint function using the American Shoulder and Elbow Society (ASES) shoulder score, VAS score, Constant-Murley Shoulder Outcome (Constant) score, and DASH score. RESULTS: A total of 40 patients were monitored for 14-16 months, averaging 15.2 ± 0.3 months. All fractures were healed between 14-25 weeks from X-rays, averaging 17.6 ± 5.4 weeks. Both the AA and PA groups had similar shoulder score changes. However, the AA group did better. In all cases, ASES shoulder scores were outstanding at 80%. Radiographs demonstratedno traumatic arthritis or internal fixation failure consequences like screw loosening or breakage. CONCLUSION: It was concluded that Ideberg type III glenoid fracture reduction with an anterior small incision and superior closed pinning hollow lag screw internal fixation could be successful.

INTRODUCTION: Postoperative fracture site infection can lead to notable patient morbidity, increase cost of care, and further contribute to healthcare disparities globally. Dogma suggests surgical blades as a vehicle for introducing bacteria into the surgical site; however, there is a paucity of literature to support this claim. This study uses advanced DNA sequencing to detect bacterial DNA on surgical blades used in upper extremity fracture surgeries. METHODS: This was a prospective study, conducted at a high-volume level 1 trauma center. All acute, closed upper extremity fractures requiring surgical stabilization were consecutively enrolled in a prospective fashion. The primary end point was the presence of bacterial DNA on the surgical blade using next-generation sequencing (NGS). At the time of surgery, two blades were sterilely opened. One blade served as the control while the other was used for the initial skin incision. Two negative control blades were opened directly into a sterile container. Two positive control blades were used for skin incision through known infections. All samples were sent for NGS analysis. RESULTS: Forty patients were enrolled in this study. The median age was 33.5 years, and 30% were female; the median body mass index was 26.52. Humerus fractures were the most common injury (N = 17, 42.5%), followed by clavicle fractures (13, 32.5%) and radius/ulna fractures (10, 25.0%). NGS analysis revealed no contamination of test blades used for skin incision. Three control blades tested positive for bacterial DNA. Negative control blades tested negative for bacterial DNA (0/2); the positive control blades resulted positive for bacterial DNA contamination (2/2). CONCLUSION: Surgical blades used for skin incision in the upper extremity are not contaminated with bacterial DNA as analyzed by NGS. This finding challenges previous surgical dogma regarding surgical blade contamination and supports that the same surgical blade can safely be used for deeper dissection. LEVEL OF EVIDENCE: Level II study: IRB approval-IRB#848938.

Objective: To introduce a new fluoroscopic method for assessing the quality of medial and lateral joint surface reduction during internal fixation of patellar fractures and to summarize the clinical outcomes of patients treated using this method. Methods: A retrospective analysis was conducted on the clinical data of 52 patients with patellar fractures treated between January 2018 and January 2022 who met the inclusion criteria. There were 27 male and 25 female patients, aged 21-75 years, with an average age of 62 years. The types of patellar fractures included 9 transverse fractures, 37 comminuted fractures, and 6 longitudinal fractures. According to the AO/Orthopaedic Trauma Association (AO-OTA)-2018 fracture classification, there were 21 cases of type 34A, 6 cases of type 34B, and 25 cases of type 34C. The time from injury to operation ranged from 1 to 5 days, with an average of 2.3 days. Treatments included internal fixation with hollow screws or hollow screw tension bands, with or without anchor repair. During operation, the medial and lateral joint surfaces of the patella were observed using the tangential fluoroscopic method to assess the smoothness of reduction of the median ridge, lateral joint surface, medial joint surface, and lateral joint edge. Patients were followed up regularly, and X-ray films were taken to observe fracture healing. Knee joint range of motion, Böstman score, and Lysholm score were used to evaluate functional recovery. Results: The tangential fluoroscopic method for the medial and lateral joint surfaces of the patella during operation showed satisfactory reduction of the joint surfaces and good positioning of the implants. All patients were followed up 12-16 months, with an average of 13.4 months. During the follow-up, fracture displacement occurred in 1 case and titanium cable breakage in 1 case. All patella fractures healed successfully, with a healing time of 8-16 weeks (mean, 11.4 weeks). At last follow-up, knee joint range of motion ranged from 120° to 140°, with an average of 136°. The Böstman score ranged from 20 to 30, with an average of 28, yielding excellent results in 45 cases and good results in 7 cases. The Lysholm score ranged from 88 to 100, with an average of 93, yielding excellent results in 40 cases and good results in 12 cases. Conclusion: The intraoperative application of the tangential fluoroscopic method for the medial and lateral joint surfaces of the patella can quickly determine the fluoroscopic plane of the patella, accurately assess the quality of fracture reduction and the position of internal fixator, thereby improving effectiveness.

BACKGROUND: The minimally invasive approach for the treatment of displaced scapular neck or body fractures has the advantages of less trauma and minimal muscle dissection. In clinical practice, the minimally invasive approach combined with an anatomical locking plate has been used to treat scapular body fractures. In addition, we have made minor modifications to the minimally invasive approach. However, the biomechanical study about the approach combined with an anatomical locking plate in treating scapular body fractures was limited. METHODS: Finite element analysis (FEA) was used to conduct the biomechanical comparison between the anatomical locking plate (AP model) and reconstructive plate (RP model) in the treatment of scapular body fractures through the modified minimally invasive approach. A healthy male volunteer with no history of scapula or systemic diseases was recruited. High-resolution computed tomography images of his right scapula were obtained. Two scapula models were constructed and analyzed by the software of Mimics 21.0, Geomagic Wrap 2021, SolidWorks 2021, and ANSYS Workbench 2022, respectively. RESULTS: Through static structural analysis, in terms of equivalent von Mises stress, equivalent elastic strain, and total deformation, the AP model exhibited superior safety characteristics, enhanced flexibility, and anticipated stability compared with the RP model. This was evidenced by lower maximum stress, lower maximum strain and displacement. CONCLUSION: The minimally invasive approach combined with an anatomical locking plate for scapular body fractures had better biomechanical stability. The study provided a biomechanical basis to guide the clinical treatment of scapular body fractures.

BACKGROUND: As one of the most challenging fractures to orthopedic surgeons, acetabular fractures show a wide range of incidence among countries and regions with even more variance in the treatment modalities. In this study, we aimed to investigate the epidemiology of acetabular fractures, and to compare the rate of subsequent total hip arthroplasty (THA) between nonoperative and operative treatments in South Korea using a medical claims database. METHODS: This was a retrospective study using the Korean Health Insurance Review and Assessment database. Patients admitted for acetabular fractures from January 2007 to December 2018 were identified using International Classification of Diseases-10 codes. Kaplan-Meier survival analysis was used to compare the cumulative incidence of THA between two groups. We also evaluated the survivorship of operative group according to the type of institutions. RESULTS: The incidence rate of acetabular fractures increased by 28% between 2007 and 2018. Acetabular fractures were more common in men (62%) than women (38%), and most common in the patients older than 80 years. The number of acetabular fractures was estimated to increase 1.7-fold in 2030 compared to 2018. Operative treatment accounted for 16% of cases, and nonoperative treatment for 84%. The incidence of subsequent THA was higher in the operative treatment group than in the nonoperative group (P < 0.001). The higher rate in the operative treatment group is probably related with the severity of the fracture type. The rate of subsequent THA was higher in patients who initially treated in general hospitals compared with those who were initially treated in tertiary hospitals. CONCLUSION: The incidence of acetabular fractures is increasing in South Korea, in line with global trends. Most acetabular fractures are treated conservatively, and those who receive surgery are more likely to require a subsequent THA. Patients who were operated in general hospitals had highest possibility of subsequent THA after acetabular fractures.
