OBJECTIVE:
To retrospectively analyze the clinical efficacy of olecranon osteotomy approach in the treatment of Dubberley type Ⅲ coronal fractures of the distal humerus and summarize the treatment experience.
METHODS:
From January 2016 to June 2020, 17 patients (5 males and 12 females) with Dubberley type Ⅲ coronal fractures of the distal humerus were treated by olecranon osteotomy approach. The age ranged from 37 to78 years old with an average of (58.5±12.9) years old. According to Dubberley classification, there were 5 cases of type Ⅲ A and 12 cases of type Ⅲ B. The curative effect was evaluated using the Borberg-Morrey elbow function score. The flexion, extension and rotation range of motion of the elbow joint, complications and postoperative imaging evaluation were recorded.
RESULTS:
All the 17 patients got bony union. The follow-up time ranged from 12 to 33 months with an average of (15.6±5.6) months. There was 1 case of ischemic necrosis of capitulum humeri, 2 cases of traumatic arthritis and 1 case of heterotopic ossification, 1 case of malunion of fracture. The range of motion was (114.80±19.50) °. The Broberg-Morrey score was 85.3±8.2, excellent in 5 cases, good in 9 cases, fair in 3 cases and poor in 0 case.
CONCLUSION
Through olecranon osteotomy approach, the articular surface of distal humerus could be fully exposed, and the operation is convenient. Anatomical reduction and rigid fixation of the articular surface of distal humerus are the key factors for the succesful outcome.

OBJECTIVE:
To investigate the clinical efficacy of picture archiving and communication system (PACS) and Photoshop assisted isosceles triangle osteotomy and Kirschner wire fixation with tension band in the treatment of cubitus varus in children.
METHODS:
The clinic data of 20 children with cubitus varus treated with isosceles triangle osteotomy of distal humerus and Kirschner wire fixation with tension band from October 2014 to October 2019, were retrospectively analyzed. There were 13 males and 7 females, aged from 3.2 to 13.5 years old, the median age was 6.65 years old. PACS system was applied for the osteotomy design preoperatively, simulating and measuring the side length of isosceles triangle osteotomy. Then, Photoshop system was used to simulate the preoperative and postoperative osteotomy graphics, which could guide precise osteotomy during operation.
RESULTS:
All the 20 patients were followed up for 20 to 24 months, with a median of 22.5 months. At the last follow-up, the carrying angle of the affected limb was 5 ° to 13 °, with a median of 8.3 °. The clinical efficacy was evaluated according to the Flynn elbow function score:excellent in 16 cases, good in 2 cases, and fair in 2 cases.
CONCLUSION
The treatment of cubitus varus in children by isosceles triangle osteotomy and Kirschner wire fixation with tension band assisted by PACS and Photoshop system has shown good clinical outcome.

PURPOSE:
The aim of this study was to analyze if any difference exists on the type of immobilisation (above elbow vs. below elbow) in the conservative treatment of distal end radius fractures in adults.
METHODS:
The study was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses. An electronic literature search was performed up to 1st October 2021 in Medline, Embase, Ovid and Cochrane database using the search terms, "distal end radius fractures OR fracture of distal radius", "conservative treatment OR non-surgical treatment", "above elbow immobilisation" and "below elbow immobilisation". Randomized clinical trials written in English, describing outcome of distal end radius fractures in adults by conservative or non-surgical means using above elbow immobilisation or below elbow immobilisation were included and assessed according to the risk of bias assessment (RoB2) tool by Cochrane collaboration. Non-randomized clinical trials, observational studies, retrospective studies, review articles, commentaries, editorials, conference presentations, operative techniques and articles without availability of full text were excluded from this review. The meta-analysis was performed using Review Manager version 5.4.1 (The Cochrane Collaboration, Copenhagen, Denmark).
RESULTS:
Six randomized clinical trials were included for quantitative review. High heterogeneity (I2 > 75%) was noted among all the studies. The standard mean difference (MD) between the disability of the arm, shoulder and hand scores in both the groups was 0.52 (95% CI: -0.28 to 1.32) which was statistically non-significant. There was no statistical difference in the radial height (MD = 0.10, 95% CI: -0.91 to 1.12), radial inclination (MD = 0.5, 95% CI: -1.88 to 2.87, palmar tilt (MD =1.06, 95% CI: -0.31 to 2.43) and ulnar variance (MD = 0.05, 95% CI: -0.74 to 0.64). It was observed that shoulder pain occurred more commonly as a complication in above elbow immobilisation and the values were statistically significant (above elbow: 38/92, 41.3%; below elbow: 19/94, 20.2%).
CONCLUSION
This two-armed systematic review on the above elbow or below elbow immobilisation to be used for conservative treatment of the distal end radius fracture in adults resulted in non-significant differences in terms of functional and radiological scores among the 2 groups but significant increase in the complication rates in the above elbow group.

OBJECTIVE:
To evaluate the effectiveness of limited internal fixation combined with a hinged external fixator in the treatment of peri-elbow bone infection.
METHODS:
The clinical data of 19 patients with peri-elbow bone infection treated with limited internal fixation combined with a hinged external fixator between May 2018 and May 2021 were retrospectively analyzed. There were 15 males and 4 females with an average age of 44.6 years (range, 28-61 years). There were 13 cases of distal humerus fractures and 6 cases of proximal ulna fractures. All the 19 cases were infected after internal fixation of fracture, and 2 cases were complicated with radial nerve injury. According to Cierny-Mader anatomical classification, 11 cases were type Ⅱ, 6 cases were type Ⅲ, and 2 cases were type Ⅳ. The duration of bone infection was 1-3 years. After primary debridement, the bone defect was (3.04±0.28) cm, and the antibiotic bone cement was implanted into the defect area, and the external fixator was installed; 3 cases were repaired with latissimus dorsi myocutaneous flap, and 2 cases were repaired with lateral brachial fascial flap. Bone defects repair and reconstruction were performed after 6-8 weeks of infection control. The wound healing was observed, and white blood cell (WBC), erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) were reexamined regularly after operation to evaluate the infection control. X-ray films of the affected limb were taken regularly after operation to observe the bone healing in the defect area. At last follow-up, the flexion and extension range of motion and the total range of motion of the elbow joint were observed and recorded, and compared with those before operation, and the function of the elbow joint was evaluated by Mayo score.
RESULTS:
All patients were followed up 12-34 months (mean, 26.2 months). The wounds healed in 5 cases after skin flap repair. Two cases of recurrent infection were effectively controlled by debridement again and replacement of antibiotic bone cement. The infection control rate was 89.47% (17/19) in the first stage. Two patients with radial nerve injury had poor muscle strength of the affected limb, and the muscle strength of the affected limb recovered from grade Ⅲ to about grade Ⅳ after rehabilitation exercise. During the follow-up period, there was no complication such as incision ulceration, exudation, bone nonunion, infection recurrence, or infection in the bone harvesting area. Bone healing time ranged from 16 to 37 weeks, with an average of 24.2 weeks. WBC, ESR, CRP, PCT, and elbow flexion, extension, and total range of motions significantly improved at last follow-up ( P<0.05). According to Mayo elbow scoring system, the results were excellent in 14 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 89.47%.
CONCLUSION
Limited internal fixation combined with a hinged external fixator in the treatment of the peri-elbow bone infection can effectively control infection and restore the function of the elbow joint.

OBJECTIVE:
To explore the feasibility and early effectiveness of computer-simulated osteotomy based on the health-side combined with guide plate technique in the treatment of cubitus varus deformity in adolescents.
METHODS:
The clinical data of 23 patients with cubitus varus deformity who met the selection criteria between June 2019 and February 2023 were retrospectively analyzed. There were 17 males and 6 females, ranging in age from 4 to 16 years with an average of 8.5 years. The time from injury to operation was 1-4 years. The angle of distal humerus rotation was defined by humeral head posterior inclination angle using low radiation dose CT to scan the patient's upper extremity data at one time, and the preoperative rotation of the distal humerus on the affected side was (33.82±4.39)°. The CT plain scan data were imported into 9yuan3D digital orthopaedic system (V3.34 software) to reconstruct three-dimensional images of both upper extremities. The simulated operation was performed with the healthy upper extremity as the reference, the best osteotomy scheme was planned, overlapped and compared, and the osteotomy guide plate was prepared. The patients were followed up regularly after operation, and the formation of callus in the osteotomy area was observed by X-ray examination. Before and after operation, the carrying angle of both upper extremities (the angle of cubitus valgus was positive, and the angle of cubitus varus was negative) and anteversion angle were measured on X-ray and CT images. At the same time, the flexion and extension range of motion of elbow joint and the external rotation range of motion of upper extremity were measured, and Mayo score was used to evaluate the function of elbow joint.
RESULTS:
The operation time ranged from 34 to 46 minutes, with an average of 39 minutes. All patients were followed up 5-26 months, with a mean of 14.9 months. All the incisions healed by first intention after the operation; 2 patients had nail path irritation symptoms after Kirschner wire fixation, which improved after dressing change; no complication such as breakage and loosening of internal fixators occurred after regular X-ray review. Continuous callus formed at the osteotomy end at 4 weeks after operation, and the osteotomy end healed at 8-12 weeks after operation. At last follow-up, the carrying angle, anteversion angle, external rotation range of motion, and extension and flexion range of motion of the elbow joint of the affected side significantly improved when compared with preoperative ones ( P<0.05). Except for the extension range of motion of the healthy elbow joint ( P<0.05), there was no significant difference in other indicators between the two sides ( P>0.05). At last follow-up, the Mayo elbow score was 85-100, with an average of 99.3; 22 cases were excellent, 1 case was good, and the excellent and good rate was 100%.
CONCLUSION
Computer-simulated osteotomy based on health-side combined with guide plate technique for treating cubitus varus deformity in adolescents can achieve precise osteotomy, which has the advantages of short operation time and easy operation, and the short-term effectiveness is satisfactory.

PURPOSE:
The purpose of this study was to assess and compare elbow range of motion, triceps extension strength and functional results of type C (AO/OTA) distal humerus fractures treated with bilateral triceps tendon (BTT) approach and olecranon osteotomy (OO). At the same time, we are also trying to know whether BTT approach can provide sufficient vision for comminuted intra-articular fractures of the distal humerus, and whether it is convenient to convert to the treatment to total elbow arthroplasty (TEA) or OO.
METHODS:
Patients treated with OO and BTT approaches for type C distal humerus fractures between July 2014 and December 2017 were retrospectively reviewed. Inclusion criteria include: (1) patients' age were more than 18 years old, (2) follow-up was no less than 6 months, and (3) patients were diagnosed with type C fractures (based on the AO/OTA classification). Exclusion criteria include: (1) open fractures (Gustillo type 2 or type 3), (2) treated by other approaches, and (3) presented with combined injuries of ipsilateral upper extremities, such as ulnar nerve. Elbow range of motion and triceps extension strength testing were completely valuated, when the fractures had healed. Assessment of functional results using the Mayo elbow performance score and complications were conducted in final follow-up. The data were compared using the two tailed Student's t-test. All data were presented as mean ± standard deviation.
RESULTS:
Eighty-six patients of type C distal humerus fractures, treated by OO and BTT approach were retrospectively reviewed between July 2014 and December 2017. Fifty-five distal humerus fractures (23 males and 32 females, mean age 52.7 years) treated by BTT approach or OO were included in this study. There were 10 fractures of type C1, 16 type C2 and 29 type C3 according to the AO/OTA classification. Patients were divided into two surgical approach groups chosen by the operators: BTT group (28 patients) and OO group (27 patients). And the mean follow-up time of all patients was 15.6 months (range, 6-36 months). Three cases in BTT group were converted to TEA, and one converted to OO. Only one case in BTT group presented poor articular reduction with a step more than 2 mm. There were not significantly different in functional outcomes according to the Mayo elbow performance score, operation time and extension flexion motion are values between BTT group and OO group (p > 0.05). Complications and reoperation rate were also similar in the two groups. Triceps manual muscle testing were no significant difference in the two groups, even subdivided in elder patients (aged >60 years old).
CONCLUSION
BTT is a safe approach to achieve similar functional result comparing with OO. BTT were not suitable for every case with severe comminuted pattern, but it avoids the potential complications related to OO, and has no complications concerning with triceps tendon. It is convenient for open reduction internal fixation and flexible to be converted to OO, as well as available to be converted to TEA in elder patients.

Chinese Journal of Traumatology 2022;25(6):336-344
PURPOSE:
Olecranon fractures are particularly vulnerable to distraction and subsequent fracture dislocation due to the high tensile forces. Surgical treatment aims at reducing the fracture and restoring the anatomical joint surface condition, as well as neutralizing the strain inhibiting fracture healing. The XS nail® (Intercus GmbH, Bad Blankenberg, Germany), an intramedullary implant exerting compression across the entire fracture surface, unlike plates, leaves a minimal extra-cortical profile, and can be secured with threaded locking wires, thereby retaining the anatomical reduction without displacement or steps within the articular surface, which was often found in tension band wiring. After encouraging initial results, the long-term outcome was assessed.
METHODS:
This retrospective study evaluated the long-term outcome of patients surgically treated at our trauma center between January 2002 and December 2005 using the XS nail®. Patients over the age of 18 years eligible for the study must have undergone surgery for isolated, recent (less than 14 days) traumatic olecranon fractures, without concomitant injuries to the ipsilateral elbow and forearm. Further exclusion criteria were pseudarthrosis, re-fractures and osteotomy for distal humerus surgery, as well as polytraumatized patients unable to aid in their own recovery. Data were retrospectively gathered by standardised questionnaire and patient records, as well as surgery and anesthesiology reports. Data analysis was performed using Microsoft Office Excel® 2016.
RESULTS:
There were 32 patients, 13 males (mean age 49.0 years) and 19 females (mean age 68.9 years) with 11 Schatzkers type D, 7 each type A and C, 5 type B and 2 type E at an average of 55.2 months, all showing complete consolidation. Of them, 6 patients had a loss of range of motion with more than 10° in the sagittal plane, and only 1 patient exceeded 10° reduction of supination. Twenty-five patients reported being pain-free under all circumstances, and all but 2 patients (93.75%) had returned to their previous activity level. The average disabilities of the arm, shoulder and hand score was 21.15 (range 0-88.3), and the overall Mayo elbow performance index was 91.87, without complications, such as wound infection, neurovascular impairment or premature hardware removal.
CONCLUSION
Using the XS nail® system, all fracture types can be successfully treated and the rate of complications was lower than that treated by standard methods published in current literature. An excellent functional outcome, high range of motion as well as good retention of reduction without soft tissue irritation makes this a very suitable implant for fractures subject to tension.

BACKGROUND:
The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture.
METHODS:
The electronic searches were systematically performed in PubMed, EmBase, Cochrane library, and Chinese National Knowledge Infrastructure from initial inception till December 2019. The primary endpoint was the incidence of excellent/good elbow function, and the secondary endpoints included Mayo elbow performance score, duration of operation, blood loss, and complications.
RESULTS:
Nine studies involving a total of 637 patients were selected for meta-analysis. There were no significant differences between olecranon osteotomy and triceps-sparing approach for the incidence of excellent/good elbow function (odds ratio [OR]: 1.37; 95% confidence interval [CI]: 0.69-2.75; P = 0.371), Mayo elbow performance score (weight mean difference [WMD]: 0.17; 95% CI: -2.56 to 2.89; P = 0.904), duration of operation (WMD: 4.04; 95% CI: -28.60 to 36.69; P = 0.808), blood loss (WMD: 33.61; 95% CI: -18.35 to 85.58; P = 0.205), and complications (OR: 1.93; 95% CI: 0.49-7.60; P = 0.349). Sensitivity analyses found olecranon osteotomy might be associated with higher incidence of excellent/good elbow function, longer duration of operation, greater blood loss, and higher incidence of complications as compared with triceps-sparing approach.
CONCLUSIONS
This study found olecranon osteotomy did not yield additional benefit on the incidence of excellent/good elbow function, while the duration of operation, blood loss, and complications in patients treated with olecranon osteotomy might be inferior than triceps-sparing approach.

OBJECTIVE:
To investigate the clinical effect of double mini-locking plates in the treatment of ulna olecranon fractures.
METHODS:
From March 2017 to May 2020, 19 patients with olecranon fractures were treated with double mini locking plates, including 12 males and 7 females, aged from 20 to 75 years old with an average of (40.50±7.62) years old;10 patients had the injuries on the left side and 9 patients on the right side. All the 19 patients were fresh closed fractures without ulnar coronoid process fracture, elbow dislocation and other injuries. The fracture healing time and complications were recorded, and the clinical efficacy was evaluated by Mayo elbow performance score (MEPS) before operation and 12 months after operation.
RESULTS:
All the 19 patientswas followed up, and the duration ranged from 12 to 17 months with an average of (13.51±3.17) months. Postoperative follow-up showed all fractures healed. Fracture healing time ranged from 2 to 6 months, with an average of(3.77±1.24) months. There was no internal fixation fracture, screw loosening, infection, internal fixation irritation, heterotopic ossification, elbow stiffness and other complications occurred. The MEPS score of affected elbow at 12 months after operation was 91.26±3.87, which was significantly different from that before operation 56.18±9.56 (
CONCLUSION
It is a reliable fixation method to treat olecranon fracture with double mini locking plate. The incision lengh is small and the fracture fixation is reliable. Elbow joint function exercise can be performed early after operation. Postoperative internal fixation has less skin irritation and satisfactory elbow joint function recovery.

China Journal of Orthopaedics and Traumatology 2020;33(12):1119-1127
OBJECTIVE:
To establish an individualized Nomogram prediction model for predicting the postoperative recovery of patients with triad of elbow (TE) by analyzing risk factors of triad of elbow joint.
METHODS:
From January 2012 to December 2018, 116 patients with TE who met the criteria were collected. The independent risk factors were screened by univariate Logistic regression analysis. The statistically significant risk factors were included in the multivariate Logistic regression model. The R software was used to establish the Nomogram diagram model to predict the postoperative recovery of TE patients. C index was used to verify the discrimination, Calibration plot of the model, and the decision curve (decision curve analysis, DCA) to verify the net clinical benefit rate of the model.
RESULTS:
Forty-four of the 116 patients with TE developed symptoms after operation, with an incidence of 37.93%. Age (
CONCLUSION
The Nomogram for predicting postoperative results of TE patients based on six independent risk factors:age, work, smoking, Mason classification of radial head, Regan-Morrey classification of coronal process and immobilization time of elbow joint after operation, has good distinguishing capacity and consistency. Thepredictive model could help clinicians to identify high risk population and establish appropriate intervention strategies.
