RESUMO
BACKGROUND: To assess the accuracy of robot-assisted Magerl screw placement and explore the factors affecting the accuracy. METHODS: A retrospective analysis of patients who underwent robot-assisted Magerl screw placement was performed. The accuracy of Magerl screw placement was evaluated according to the Gertzbein and Robbins scale. RESULTS: 47 Magerl screws were placed in 24 consecutive patients. 32 Magerl screws were narrower than the C2 isthmus height and 26 of them were grade A. 15 Magerl screws were wider than the C2 isthmus height and all of them were grade B. Temporary fixation after decompression and a smaller difference between the C2 isthmus height and screw diameter were associated with a higher probability of cortical breach. CONCLUSION: The accuracy of robot-assisted Magerl screw placement was excellent. Temporary fixation after decompression and a smaller difference between the C2 isthmus height and screw diameter increased the risk of cortical breach.

Objective:To compare the outcomes of isolated Mason type Ⅱ radial head fracture between operative and non-operative treatments.Methods:A retrospective study was conducted to analyze the data of patients who had been treated for isolated Mason type Ⅱ radial head fracture either operatively or nonoperatively at Department of Trauma and Orthopaedics, Beijing Jishuitan Hospital, Capital Medical University from January 2017 to October 2020. The patients were divided into a non-operative group and an operative group according to their treatment method. After 1:1 propensity score matching method was used to match the patients in the 2 groups, a total of 58 pairs of patients were successfully matched. In the operative group, there were 24 males and 34 females with a mean age of (40±14) years and a body mass index of (23.7±3.4) kg/m 2; in the non-operative group, there were 22 males and 36 females with a mean age of (42±13) years and a body mass index of (23.5±3.9) kg/m 2. Elbow flexion-extension, forearm rotation, Mayo elbow performance score (MEPS), Quick-disabilities of the arm, shoulder and hand (q-DASH) score and complications were compared between the 2 groups. Results:There was no significant difference in the baseline data between the 2 groups, indicating comparability ( P>0.05). All the patients were followed up for (24±9) months. At the last follow up in the operative and the non-operative groups, respectively, the elbow flexion-extension was 134° (132°, 136°) and 134°(131°, 136°), the forearm rotation 176° (174°, 179°) and 178° (175°, 179°), the MEPS 100 (100, 100) and 100 (100, 100), the q-DASH score 0 (0, 0) and 0 (0, 0), showing no significant differences between the 2 groups in the above items ( P>0.05). Elbow pain was reported respectively in 4 (6.9%) and 6 (10.3%) patients in the operative and non-operative groups, showing no significant difference between the 2 groups ( P>0.05). Conclusion:The outcomes of operative and non-operative treatments of isolated Mason type Ⅱ radial head fracture are comparable.
RESUMO
Objective:To compare the efficacy between olecranon sled fixation and tension band wiring fixation in the treatment of Mayo ⅡA olecranon fractures.Methods:A retrospective study was conducted to analyze the data of 54 patients with Mayo ⅡA olecranon fracture who had been admitted to Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital from October 2018 to February 2021. There were 20 males and 34 females with an age of (45.5±17.7 years), and 36 left and 18 right sides. They were divided into 2 groups according to different methods of internal fixation. Group A (25 cases) was subjected to olecranon sled fixation and group B (29 cases) to tension band wiring fixation. Preoperative data, operation time, reoperations and complications during follow-up were recorded and compared between the 2 groups. In both groups at the last follow-up, the range of the elbow motion, the Mayo elbow performance score (MEPS) and the Disabilities of the Arm, Shoulder and Hand (DASH) score were recorded to evaluate the elbow function.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). There were no significant differences between the 2 groups either in follow-up time [(32.8±8.9) months for group A and (35.8±9.0) months for group B] or in operation time [60.0 (60.0, 82.5) min for group A and 60.0 (60.0, 67.5) min for group B] ( P>0.05). At the last follow-up in group A and group B, respectively, the flexion and extension of the elbow was 141.0°±8.4° and 140.0 (140.0, 150.0)°, the pronation-supination 180.0 (175.0, 180.0)° and 180.0 (175.0, 180.0)°, the MEPS score 100.0 (85.0, 100.0) and 100.0 (92.5, 100.0), and the DASH score 4.2 (1.7, 6.3) and 5.8 (1.3, 8.3), all showing no statistically significant differences between the 2 groups ( P>0.05). Olecranon skin irritation occurred in 5 patients (20.0%,5/25) in group A and in 15 patients (51.7%,15/29) in group B, and 7 patients (28.0%,7/25) in group A and 21 patients (72.4%,21/29) in group B underwent removal of internal fixation, both showing statistically significant differences between the 2 groups ( P<0.05). Conclusion:In the treatment of Mayo ⅡA olecranon fractures, compared with tension band wiring fixation, olecranon sled fixation may lead to comparable efficacy in fixation and functional recovery, but significantly reduced rates of complications and internal fixation removal.
RESUMO
Objective:To report our experience in using the Ilizarov technique to treat bone defects secondary to Gustilo Ⅲb open tibial fractures with negative clinical signs and serological inflammatory markers.Methods:A retrospective study was performed to analyze the 19 patients with bone defects secondary to Gustilo Ⅲb open tibial fracture who had been treated at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital between January of 2010 and June of 2021. They were 15 males and 4 females with an age of (41±11) years. Their inclusion criteria: undergoing treatment with Ilizarov technique (consecutive compression-distraction or bone transport), soft tissue coverage procedures resulting in wound closure and negative clinical infection signs for at least 3 months and normal serological inflammatory markers, and follow-up for more than 3 months after frame removal. Three-phase bone scan was performed for the patients before the present surgery. Debridement, sampling of deep tissues for bacterial culture, and external stabilization with a fixator were performed in the present surgery. Osteotomy for compression-distraction or bone transport technique was carried out at 1 stage or 2 stages. Systemic antibiotic therapy for 6 weeks was continued for those with positive microbiological analysis guided by antibiogram. Recorded were results of intra-operative pus detection around defects, microbiological findings, length of bone defect reconstructed, rate and time of infection recurrence during treatment, fracture union rate, bone healing index, bony and functional results.Results:The interval between primary injury to the present surgery was (10±8) months. The preoperative three-phase bone scan showed infection free in 8 cases, chronic osteomyelitis in 7 cases, and suspicious infection in 4 cases. No pus was found during intra-operative debridement in all. The intra-operative microbiological detection was positive in 1 sample in 1 patient (infection free indicated by bone scan), and in ≥2 samples in 3 patients (bone scan indicating non-infection, infection not excluded and osteomyelitis in 1 case each). The length of bone defect reconstructed was (8±3) cm. The follow-up after the present surgery was (37±15) months. Fracture union was achieved in all cases, with a bone healing index of (1.7±0.5) months/cm. Clinical infection signs were observed 1 (1, 1) month after the present surgery in 6 patients whose microbiological results were all negative. All the 6 patients ended up with no clinical recurrence after empirical use of systemic antibiotics in 5 and radical debridement in one. The bony results showed 16 excellent and 3 good cases while the functional results showed 10 excellent and 9 good cases.Conclusions:In treatment of bone defects secondary to Gustilo Ⅲb open tibial fractures with negative clinical signs and serological inflammatory markers, constant vigilance is needed against low-grade infection. Intra-operative multiple sampling of deep tissues with a standardized protocol and microbiological testing are extremely valuable for diagnosis of fracture-related infections.
RESUMO
Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.
RESUMO
As the National Health Commission changes the management of novel corona virus infection, the situation and preventive policies for controlling the epidemic have also entered a new stage in China. Perioperative care strategies for orthopedic trauma such as designated isolation and nucleic acid test screening have also been adjusted in the new stage. Based on the perioperative work experiences in the new stage of epidemic from the frontline anti-epidemic staff of orthopedics in domestic hospitals and combined with the literature and relevant evidence-based medical data in perioperative care of orthopedic trauma patients under the current anti-epidemic policies at home and abroad, Chinese Orthopedic Association and Chinese Society of Traumatology organized relevant experts to formulate the Guideline for clinical perioperative care of orthopedic trauma patients in the new stage of novel corona virus infection ( version 2023). The guideline summarized 16 recommendations from the aspects of preoperative diagnosis and treatment, infection prevention, emergency operation and postoperative management to systematically standardize the perioperative clinical pathways, diagnosis and treatment processes of orthopedic trauma in the new stage of novel corona virus infection, so as to provide a guidance and reference for hospitals at all levels to carry out relevant work in current epidemic control policies.
RESUMO
Elbow arthrolysis is the most commonly used treatment for elbow stiffness. Ulnar nerve complications are one of the most important evaluation indicators of postoperative health status. However, there is no consensus on the management of ulnar nerve and the control of surgical indications. Combining relevant literature and clinical experience, this review discussed the necessity of ulnar nerve release and the choice of ulnar nerve operations during elbow arthrolysis with or without preoperative ulnar nerve symptoms. It is considered that more attention should be paid to the management of ulnar nerve complications and further research should be performed.
RESUMO
Objective:To study the clinical efficacy of modified open elbow arthrolysis in the treatment of traumatic elbow stiffness.Methods:A retrospective analysis was performed on 120 patients who underwent modified open elbow arthrolysis in Beijing Jishuitan Hospital from January 2018 to December 2020. The age of the included patients was (37.7±12.4) years (ranged 18-64 years), including 54 males and 66 females. The medical records were reviewed, the range of motion (ROM) and functional status of the patients before operation and at the last follow-up were compared including visual analogue scale (VAS), Mayo elbow performance score (MEPS), Disabilities of the arm, shoulder and hand (DASH) score. Complications and secondary operations were also recorded. Measurement data with normal distribution were presented as mean ± standard deviation( ± s) and comparison between groups was conducted using the t-test; Measurement data of skewed distribution were expressed as M ( Q1, Q3), and Rank-sum test was used for inter-group comparison. Results:The preoperative extension of 120 patients was 43.6° (33.8°, 60.1°), the flexion was 78.7° (59.8°, 98.1°), and the flexion-extension ROM was 25.6° (0.0°, 54.5°); the preoperative pronation was 51.8° (33.0°, 67.0°), the supination was 85.1° (65.7°, 90.0°), and the rotation ROM was 136.9° (99.1°, 157.5°). Postoperative extension was 14.2° (7.0°, 24.8°), flexion was 129.5° (120.0°, 138.1°), flexion-extension ROM was 115.5° (94.4°, 127.3°); postoperative pronation was 65.0° (47.1°, 75.0°), the supination was 88.3° (78.6°, 90.0°), and the rotation ROM was 151.9° (131.7°, 163.4°). Postoperative extension, flexion, flexion-extension ROM, pronation, supination, and rotation ROM were all higher than those before operation, and the differences were statistically significant ( P<0.001). The VAS of 120 patients was 1.0 (0.0, 3.0) scores before operation and 0.0 (0.0, 1.0) scores after operation. The MEPS was 60.0 (50.0, 75.0) scores before operation and 100.0 (85.0, 100.0) scores after operation. The preoperative DASH was 37.5 (20.1, 51.3) scores, and the postoperative DASH was 7.9 (3.3, 13.3) scores. The postoperative VAS, MEPS, and DASH were significantly improved compared with those before operation, and the differences were statistically significant ( P<0.001). Residual ulnar nerve symptoms occurred in 18 cases, recurrence of heterotopic ossification in 42 cases, and hematoma in 3 cases. Conclusions:Modified open elbow arthrolysis is a safe and effective surgical method for the treatment of traumatic elbow stiffness. It can significantly improve the function of the patient, reduce the occurrence of elbow instability, avoid the use of external fixators, and reduce the cost of the patient.
RESUMO
Objective:To investigate the therapeutic effects of sled board internal fixation on the treatment of olecranon fractures.Methods:The clinical data were retrospectively analyzed of the 21 patients with olecranon fracture who had been treated with sled board internal fixation at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital from May 2019 to January 2021. They were 11 males and 10 females with 14 left and 7 right sides affected, aged from 18 to 68 years (mean, 42.0 years). By the preoperative Mayo classification for olecranon fractures, one case was type ⅠA, 11 cases were type ⅡA and 9 cases type ⅡB; by the Schatzker classification, one case was type A, 4 cases were type B and 16 cases type C. The operation time and the complications were recorded; at the last follow-up, the range of motion of the elbow joint was recorded and the elbow function and pain were evaluated by the Mayo elbow performance score (MEPS) and visual analogue scale (VAS).Results:The 21 patients were followed up for 13 to 34 months (mean, 19.6 months) after operation. At the last follow-up, the flexion and extension of the affected elbow averaged 139.8° (from 125° to 160°), and the pronation-supination 177.9° (from 160° to 180°). The operation time averaged 77.8 min (from 40 to 135 min). Postoperative olecranon skin discomfort developed in 4 patients, 2 of whom underwent removal of internal fixation; no such complication as internal fixation breakage, screw loosening, incision infection or elbow stiffness was observed in the other 17 cases. At the last follow-up, the MEPS scores averaged 97.9 points (from 85 to 100 points) and the VAS scores 0.2 points (from 0 to 2 points).Conclusion:The sled board internal fixation can result in good therapeutic effects on the treatment of olecranon fractures.
RESUMO
Objective:To characterize the humeral head necrosis after open reduction and anatomic locking plate fixation of complex proximal humeral fractures.Methods:A retrospective study was conducted of the 20 patients who had been treated for humeral head necrosis after surgery of complex proximal humeral fracture at Department of Traumatic Orthopaedics, Beijing Jishuitan Hospital from September 2012 to June 2020. They were 7 males and 13 females with an average age of 57.4 years (from 35 to 84 years). Analyzed were their fracture types, time for diagnosis of humeral head necrosis, length of the medial residual bone, thickness of the humeral head and shoulder function.Results:The 20 patients were followed up for 8 to 104 months (average, 48.3 months). According to the Neer classification, there were 8 three-part fractures and 12 four-part fractures; shoulder dislocation was complicated in 10 cases. According to the AO-OTA classification, there were 16 type C fractures and 4 type B fractures. The length of the medial residual bone averaged 4.8 mm (from 0 to 10.7 mm); the medial soft tissue hinge was damaged in 18 cases and the thickness of the humeral head averaged 20.6 mm (from 13.6 to 33.0 mm). All fractures got united at the first stage after an average time of 8.4 weeks (from 5 to 12 weeks). The time for diagnosis of humeral head necrosis averaged 16.5 months (from 8 to 24 months). At the final follow-up, the Constant-Murley score of the affected side averaged 53.4 (from 22 to 74) while that of the healthy side 85.5 (from 53 to 98), with a ratio of affected side to healthy side of 62.43% (from 27.95 to 82.70%).Conclusions:Necrosis of the humeral head was common after surgery for complex proximal humerus fractures, most of which were three- or four-part ones or combined with shoulder dislocation. In most of the patients, the medial soft tissue hinge was damaged and the length of the residual medial bone usually shorter than 8 mm. Necrosis of the humeral head happened late after surgery. The function of the affected shoulder was significantly lower than that of the healthy side.
RESUMO
Objective:To evaluate the trans-subscapularis approach in the treatment of Ideberg type Ⅰa scapular glenoid fractures.Methods:A retrospective analysis was conducted in the 16 patients with Ideberg type Ⅰa scapular glenoid fracture who had been treated via the trans-subscapularis approach at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from December, 2012 to August 2019. X-ray follow-ups were conducted at 2 weeks, 6 to 8 weeks, 3 months and 12 months, and CT follow-ups at 6 to 8 weeks after operation. The Constant-Murley score and visual analogue scale (VAS) were used at the last follow- up to evaluate the postoperative shoulder function and pain in the patients.Results:The 16 patients were followed up for 9 to 101 months (average, 41.2 months). All fractures achieved bony union after 6 to 8 months (average, 6.8 weeks). The Constant-Murley scores at the last follow-up ranged from 85 to 100 points; the lateral internal rotation scores averaged 8.3 points (from 6 to 10 points), showing the level of the T12 spinous process could be palpated by the back of the hand; the VAS scores averaged 0. No patients reported internal fixation failure, postoperative infection or other complications.Conclusion:The trans-subscapularis approach can be used to treat Ideberg type Ⅰa scapular glenoid fractures due to its satisfactory clinical effects.
RESUMO
Objective:To explore the surgical treatment of isolated traumatic radial head dislocation (ITRHD) after failed close reduction.Methods:A retrospective study was conducted of the 8 patients with ITRHD who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital for operation after failed close reduction from January 2011 to December 2020. They were 2 males and 6 females, aged from 15 to 41 years (average, 27 years). The left elbow was injured in 3 patients and the right elbow in 5. At the last follow-up, elbow flexion-extension and forearm pronation-supination were recorded and Mayo Elbow Performance Score (MEPS) was used to evaluate functional recovery.Results:The 8 patients were followed up for 2 to 13 months (mean, 4.5 months). At the last follow-up, elbow flexion-extension averaged 136.9° and forearm pronation-supination 143.8°. None of the 8 patients had significant pain or joint instability. Of them, 7 had good motor function but one reported significant limitation of forearm rotation. All the 8 patients scored a full MEPS mark.Conclusions:If close reduction failed, ITRHD should be treated in time by operative treatment the efficacy of which is reliable. Fixation of the proximal radial-ulnar joint with Kirschner wire should be avoided. Early exercise for full range of elbow motion is necessary.
RESUMO
Objective:To investigate the efficacy of TiRobot navigation for hinged external fixation in elbow arthrolysis.Methods:The 11 patients were retrospectively analyzed who had been treated by elbow arthrolysis at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital using TiRobot navigation for hinged external fixation. There were 9 males and 2 females with a mean age of 39.3 years (from 21 to 66 years). Their elbow range of motion (ROM) was compared between preoperation and the final follow-up. Their visual analogue scale (VAS) and Mayo elbow performance score (MEPS) and complications were documented at the final follow-up.Results:The rotation axis of the elbow joint was positioned with the aid of intraoperative robot navigation in 11 patients.The deviation of entry point averaged 0.21 mm (from 0.05 to 0.41 mm) and the deviation of exit point 0.23 mm (from 0.06 to 0.38 mm). The follow-up time for the 11 patients averaged 25.8 months (from 16 to 32 months). Their elbow flexion and extension was 133.0° (134.9°, 138.7°) and rotation 164.6° ±17.5° at the final follow-up, significantly improved compared with their preoperative values [0.8°(0°, 33.7°) and 122.9°±49.0°] ( P<0.05). Their VAS averaged 0.2 (from 0 to 1) and MEPS 96.8 (from 85 to 100) at the final follow-up, giving 9 excellent and 2 good cases. There was no case of radial nerve injury, pin instability, pin breakage, pin infection or peri-pin fracture. Conclusion:When TiRobot navigation is used for hinged external fixation in elbow arthrolysis, the axis of rotation can be accurately located, leading to satisfactory functional outcomes for the patients.
RESUMO
Objective:To study the locational distribution characteristics of the heterotopic ossification (HO) following traumatic elbow stiffness and the risk factors for HO development at different locations.Methods:Consecutively included according to our inclusion criteria in the present study were the patients who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from January 2018 to December 2018 for elbow release due to traumatic elbow stiffness but developed postoperative HO. Their baseline data and CT data were collected and processed using Mimics 20.0. The HO distribution for each patient was characterized at the anteromedial, anterolateral, posteromedial, posterolateral, posterior, medial, lateral, and proximal radioulnar locations. The patient's original injury was categorized into 5 types: distal humerus fracture, olecranon fracture, radial head fracture, coronoid fracture, and elbow dislocation. After the univariate analysis with the HO occurrence at a specific location as the dependent variable and the original injury and baseline data as the independent variables, the factors with P value less than 0.1 were included in the logistic regression analysis to determine the risk factors for HO at each location.Results:A total of 91 patients were included in this study. Of them, 88 had posteromedial HO (96.7%, 88/91), 62 posterior HO (68.1%, 62/91), 60 posterolateral HO (65.9%, 60/91), 41 anteromedial HO (45.1%, 41/91), 26 anterolateral HO (28.6%, 26/91), 13 proximal radioulnar HO (14.3%, 13/91), 8 lateral HO (8.8%, 8/91), and 7 medial HO (7.7%, 7/91). Logistic regression analysis showed that presence of ulnar nerve symptoms ( OR=4.354, P=0.017) and presence of original elbow dislocation ( OR=2.927, P=0.042) were the independent risk factors for the anteromedial HO development and that presence of original olecranon fracture ( OR=0.277, P=0.023) was the protective factor for the anteromedial HO development. Presence of original radial head fracture was the independent risk factor for the anterolateral HO development ( OR=2.891, P=0.033) and the posterolateral HO development ( OR=3.123, P=0.043). Conclusions:HO development in patients with post-traumatic elbow stiffness is closely related to their original injury. Posteromedial HO may develop in almost all the patients. Patients with ulnar nerve symptoms and original elbow dislocation are more prone to anteromedial HO development, but patients with original olecranon fracture are less likely to develop anteromedial HO. Patients with original radial head fracture are more likely to develop anterolateral and posterolateral HO.
RESUMO
Olecranon fracture is one of the most common types of elbow fracture. The traditional surgical methods are tension band wiring and plate internal fixation. Both surgical methods can well restore the range of motion and function of the elbow, but there are still problems such as occurrence of complications and high rate of secondary surgery. Olecranon sled is a new type of internal fixation, the unique design of which helps reduce the incidence of complications. Combining relevant literature and clinical experience, the author will discuss the research progress in common internal fixation techniques for olecranon fracture, considering that the clinical effect of internal fixation is good at present, but the problems of postoperative complications and secondary operation are still worthy of attention.
RESUMO
Objective:To compare the clinical outcomes between OTA/AO-C open and closed fractures of the distal humerus treated by open reduction and internal fixation.Methods:The clinical data were retrospectively analyzed of the 70 patients who had been treated at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital for OTA/AO-C fractures of the distal humerus from January 2014 to June 2017. Of them, 22 suffered from open fractures (Gustilo types Ⅰ/Ⅱ) and 48 closed fractures. There were 18 males and 4 females with an age of (42.6±13.0) years in the open group and 21 males and 27 females with an age of (42.2±17.1) years in the closed group. Analyzed were interval from injury to surgery, hospitalization time, injury energy and functional outcomes which included range of motion (ROM) in elbow flexion and extension, ROM in elbow rotation, Mayo elbow performance score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH), complications and rate of secondary surgery.Results:There was no significant difference between the 2 groups in age, injury energy or interval from injury to surgery ( P>0.05), but there were significantly more males in the open group than in the closed group ( P=0.011). The follow-up time for all the patients averaged 34.0 months (from 25 to 54 months). There were no statistically significant differences between the 2 groups in hospitalization time [9.5(6.0, 13.0) d versus 8.5 (6.0, 11.0) d], ROM in flexion and extension [120.0° (100.0°, 137.8°) versus 128.5° (110.0°, 140.0°)], ROM in rotation [155.0° (151.3°, 155.0°) versus 155.0° (155.0°, 155.0°)], MEPS [95.0 (80.0, 100.0) versus 95.0 (80.0, 100.0)] or DASH [2.6 (0.63, 9.2) versus 1.7 (0.0, 8.5)] ( P>0.05). There were no statistically significant differences between the 2 groups either in rate of secondary surgery [36.4% (8/22) versus 33.3% (16/48)], ulnar nerve symptoms [54.5% (12/22) versus 60.4% (29/48)], local irritability in the region of internal fixation [9.1% (2/22) versus 6.3% (3/48)] or elbow stiffness [13.6% (3/22) versus 10.4% (5/48)] ( P>0.05). Conclusion:Open reduction and internal fixation can lead to similar clinical outcomes in the treatment of both open (Gustilo types Ⅰ/Ⅱ) and closed distal humeral fractures of OTA/AO-C, with no significant differences in postoperative ROM, functional scores or complications.
RESUMO
Objective:To analyze the treatment of scapular glenoid fractures via the modified Judet approach.Methods:A retrospective study was conducted of the 25 patients who had been treated for scapular glenoid fractures via the modified Judet approach and completely followed up at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from January 2014 to January 2020. They were 19 males and 6 females with an average age of 46 years (from 29 to 66 years). According to the Goss-Ideberg classification, 8 cases were diagnosed as type Ⅱ, 2 cases as type Ⅳ, 10 cases as type Ⅴ and 5 cases as type Ⅵ. 3D reconstruction of the CT scans by software Mimics 16.0 was made to confirm the diagnoses and classifications of the fractures. Articular step-off and displacement of the scapular glenoid were calculated and recorded. The functional outcomes were evaluated by Constant-Murley scoring system at 6 months postoperatively.Results:Preoperatively, the mean articular step-off was 5.8 mm (from 1.2 to 6.3 mm) and the mean displacement 7.7 mm (from 2.1 to 12.9 mm). All fractures obtained bony union within postoperative 6 months. The mean follow-up period was 58.8 months (from 7 to 92 months). The forward flexion was 158.6° (from 125° to 180°) and the external rotation 39.0° (from 30° to 45°) at 6 months postoperatively. The mean Constant-Murley score was 92.6 (from 75 to 100) at 6 months post-operatively; 19 cases were excellent (76%), 5 were good (20%) and one was fair (4%), giving an excellent to good rate of 96% (24/25).Conclusion:For scapular glenoid fractures of Goss-Ideberg types Ⅱ/Ⅳ/Ⅴ/Ⅵ, surgery via the modified Judet approach may promise satisfactory reduction and fixation and fine clinical outcomes.
RESUMO
Objective:To investigate a 3D method of radiological evaluation of extra-articular scapular fracture and the treatment outcomes.Methods:A total of 19 patients with extra-articular scapular fracture were operatively treated and completely followed up at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2014 to January 2020. They were 17 males and 2 females with an average age of 41 years (from 24 to 65 years). The medial-lateral displacement, antero-posterior angulation and glenopolar angle were measured on images of 3D reconstruction of the fractured scapulae by Mimics software. 3D reconstructions of the intact scapulae were made as controls in the patients with proximal humerus fracture matched in time and age (17 males and 2 females with an average age of 41 years). Operations were carried out via the modified Judet approach in the experimental group. The treatment outcomes in the experimental group were evaluated by the Constant-Murley absolute value scoring at 6 months after operation.Results:All the patients in the experimental group obtained a mean follow-up of 48 months (from 11 to 73 months). All fractures in the experimental group acquired anatomical reduction and fixation intraoperatively and bony union within 6 months after operation. In the experimental group, the medial-lateral displacement averaged 17.9 mm and the antero-posterior angulation 26.9° before operation while the anteflexion lifting angle 162.2°, the lateral external rotation 41.6°, and the Constant-Murley absolute value scores 93.2 points at 6 months after operation. Pre-operatively, the glenopolar angles were 34.4°±6.3° and 40.6°±6.6° for the experimental and control groups respectively, showing a significant difference between the 2 groups ( P<0.05). At 6 months after operation, the glenopolar angle was 38.4°±5.0° for the experimental group, showing a significant difference between pre- and post-operation ( P<0.05). Conclusions:3D reconstruction measurements with Mimics software help accurate characterization of extra-articular scapular fracture and evaluation of surgical indications. Open reduction and internal fixation of scapular fractures via the modified Judet approach may promise a satisfactory union rate and functional outcomes.
RESUMO
Objective:To explore the effect of combined administration of intravenous and topical tranexamic acid on perioperative blood loss in elbow arthrolysis.Methods:A retrospective analysis was conducted of 31 patients who had undergone elbow arthrolysis due to elbow stiffness from April 2019 to November 2020 at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital. An observational group of 15 patients were subjected to combined administration of intravenous and topical tranexamic acid while a control group of 16 patients to no administration of tranexamic acid. In the observational group, 15 mg/kg of tranexamic acid was injected intravenously 5 to 10 minutes before surgery and 1.0 g of tranexamic acid was injected locally in the area of anterior and posterior joint capsules after incision was closed while drainage tubes were clamped for 2 hours before release. In the control group, there was no special operative procedure while drainage tubes were also clamped for 2 hours before release. The 2 groups were compared in terms of blood loss on day 1 and day 3 after operation, drainage volume on day 1 after operation, total drainage volume, time for indwelling drainage tube, complications, and Mayo elbow performance score (MEPS) at 3 months after operation.Results:There were no statistically significant difference in preoperative general data between the 2 groups, showing they were comparable ( P>0.05).On day 1 and day 3 after operation, the blood loss was respectively (533.4±318.3) mL and (792.0±375.6) mL in the observational group, and respectively (866.4±480.5) mL and (1,403.0±636.5) mL in the control group, showing significantly differences between the 2 groups ( P<0.05). The drainage volume on day 1 after operation was (151.3±90.1) mL in the observational group and (235.0±126.1) mL in the control group, showing a significant difference between the 2 groups ( P<0.05). There was no statistically significant difference in total drainage volume or time for indwelling drainage tube between the 2 groups ( P>0.05). There were no such complications as thromboembolic events in either group. There was no significant difference in MEPS between the 2 groups at 3 months after operation ( P>0.05). Conclusions:Combined administration of intravenous 15 mg/kg and topical 1.0 g tranexamic acid may reduce blood loss on day 1 and day 3 after operation and drainage volume on day 1 after operation, and may not increase the risk of thromboembolic events, but cannot reduce total drainage volume or time for indwelling drainage tube. Application of tranexamic acid may not affect early elbow joint function after operation.
RESUMO
Objective:To investigate the operative treatments of old displaced fractures of humeral greater tuberosity and their related factors.Methods:A retrospective study was conducted of the 16 patients who had received operative treatment at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital for old displaced fractures of humeral greater tuberosity from November 2010 to March 2019 and whose complete follow-up data were available. They were 9 males and 7 females with an average age of 61 years(from 40 to 77 years). The original injury was accompanied by shoulder dislocation in 12 cases; the original displaced fracture of humeral greater tuberosity was not surgically treated in time in 8 cases; the primary surgical treatment did not lead to effective fracture reduction in 4 cases; the fracture of humeral greater tuberosity was displaced again after surgical treatment in 4 cases. Anterior displacement was observed in 2 cases, posterior displacement in 3 cases and superior displacement in 11 cases. The duration between the onset of displacement and the last operation averaged 5 months, and the displacement distance 16.5 mm. The Constant-Murley and visual analogue scale(VAS) scores were compared between preoperation and 6 months postoperation.Results:This group of patients obtained a mean follow-up of 55 months(from 16 to 118 months). Anatomical reduction of the greater tuberosity was achieved in 15 cases, leading to uneventful union. Mal-reduction occurred in one patient whose greater tuberosity was found displaced superiorly again by follow-up. For the 16 patients, the Constant-Murley absolute value scores were 37.0±11.7 and 91.0±9.9, and the flexion elevation ranges 33.0°±26.7° and 144.0°±38.5°, respectively for preoperation and 6 months postoperation, showing significant improvements between preoperation and 6 months postoperation( P<0.05). The VAS scores were 0.7±1.3 at 6 months postoperation, significantly improved than the preoperative value 4.5±1.0 ( P<0.05). Postoperatively, good shoulder function scores were not obtained by one patient who could still manage to fulfill daily life tasks. Conclusion:Open reduction and internal fixation can result in satisfactory functional outcomes in the treatment of old displaced fractures of the humeral greater tuberosity, depending on different features of fracture displacement.
