Occupational elbow musculoskeletal disorders in Tunisia: Epidemiology and socio-professional consequences.

INTRODUCTION: Musculoskeletal disorders (MSDs) are as the primary occupational disease (OD) in Tunisia. They can touch the elbow and cause occupational disability. AIMS: Describe the epidemiological and clinical characteristics of elbow MSDs recognized in Tunisia, identify the factors associated with these MSDs and assess their socio-professional impact. METHODS: Retrospective descriptive study of elbow MSDs recognized as compensable OD by the Committees for the Recognition of Occupational Diseases of National Health Insurance Fund, in Tunisia, from 2012 to 2018. RESULTS: We collected 431 cases of elbow MSDs or 8.35% of all recognized MSDs and 11.8% of recognized MSDs during the same period. The average annual incidence was 4.3 cases. Patients had a mean age of 43.59 years and a clear female predominance (82.2%). The largest provider was the textile industry (60.6%). The average length of employment was 16.78 years. Biomechanical factors were repetitive movements (92.8%), forced movements (67.1%) and prolonged static posture (7.4%). These were lateral epicondylitis (79.1%), medial epicondylitis (14.2%) and ulnar nerve syndrome (10.7%). These pathologies were associated with other MSDs including carpal tunnel syndrome (25.8%). These MSDs were responsible for 15,342 days of lost work. The rate of permanent partial incapacity was 10.6% with a job loss in 15.63%. CONCLUSION: Elbow MSDs are responsible for heavy economic and socio-professional consequences justifying the implementation of a preventive strategy adapted within risk sectors.

A rare complication of tension band fixation of olecranon osteotomy: Distal migration of K-wire.

Tension band wiring (TBW) is one of the most commonly used fixation techniques to fix olecranon osteotomies. Hardware prominence has been the most commonly reported complication of TBW. However, distal migration of Kirschner (K)-wire after TBW fixation for olecranon osteotomy has not been reported. In this case report, we presented distal migration of K-wire detected nine months after initial surgery in a 46-year-old male patient. The patient was operated on for an intraarticular distal humerus fracture using an olecranon osteotomy. The osteotomy was fixed with TBW fixation. The patient missed routine follow-ups and presented to the outpatient clinic with a complaint of skin irritation at the elbow nine months after the surgery. On radiological examination, distal migration of one K-wire was detected. The K-wire was surgically removed without any complication. Physicians should be aware of possible complications of TBW and remove fixation after fracture union to avoid unexpected complications.

Conservative treatment of congenital radial head subluxation and non-traumatic elbow locking: A case report.

Congenital radial head subluxation is relatively rare and may be overlooked due to mild symptoms. The diagnosis mainly relies on imaging and history. Observation is an option for those with insignificant symptoms, while surgical intervention, such as ulnar osteotomy or arthroscopy, is often required when dysfunction exists. A 30-year-old man was admitted with congenital radial head dislocation, which was treated with manipulative repositioning. During follow-up, the patient regained the original mobility of the elbow joint and had no recurrence of dislocation. In conclusion, in adults with congenital dislocation of the radial head, we recommend conservative treatment as a first step.

The fate of the malrotated elbow supracondylar fractures in children: is varus really a problem?

PURPOSE: To evaluate the functional and cosmetic effects of elbow supracondylar fractures (SCF) in children with residual rotational deformity. METHODS: Retrospective review cohort of patients with evidence of malrotation after treatment for SCF. An analysis of the postoperative X-ray of 305 consecutive SCF type 3 treated surgically during five years identified 46 elbows with rotational deformity that fulfilled the selection criteria and were recalled for review; only 27 patients agreed to participate. Patients were evaluated clinically and radiographically. Clinically, the elbow and shoulder ROM were assessed. The postoperative fracture rotation (PFR) was radiologically measured using the Berdis method. Results were categorized according to Flynn criteria, and functional outcomes were evaluated with the QuickDASH questionnaire. On final assessment, a radiograph of both elbows was obtained, and measures were compared. Descriptive analysis was made calculating median, range, proportions, and confidence intervals. Non-parametric tests were used to test the association between variables. RESULTS: The group had a median age of four years and a median follow-up of 52 months. Shoulder rotation was asymmetrical in 13 patients; six patients presented a change on carrying angle > 5° (4 varus/2 valgus). The higher the residual rotation, the higher the chances of an altered shoulder rotation (for each degree of PFR, the shoulder rotation was changed to 0.4°). However, there was a low correlation between the amount of rotation and the final carrying angle (r = 0.37). According to Flynn's criteria, over 95% had excellent or good results. CONCLUSION: There was a weak correlation between varus and rotational malalignment. Patients with moderate residual malrotation could be expected to have a good outcome even if some shoulder rotation changes persist.

Augmented Ulnar Collateral Ligament Repair With Structural Bioinductive Scaffold: A Biomechanical Study.

BACKGROUND: Elbow ulnar collateral ligament (UCL) repair with suture brace augmentation shows good time-zero biomechanical strength and a more rapid return to play compared with UCL reconstruction. However, there are concerns about overconstraint or stress shielding with nonabsorbable suture tape. Recently, a collagen-based bioinductive absorbable structural scaffold has been approved by the Food and Drug Administration for augmentation of soft tissue repair. PURPOSE/HYPOTHESIS: This study aimed to assess the initial biomechanical performance of UCL repair augmented with this scaffold. We hypothesized that adding the bioinductive absorbable structural scaffold to primary UCL repair would impart additional time-zero restraint to the valgus opening. STUDY DESIGN: Controlled laboratory study. METHODS: Eight cadaveric elbow specimens-from midforearm to midhumerus-were utilized. In the native state, elbows underwent valgus stress testing at 30o, 60o, and 90o of flexion, with a cyclical valgus rotational torque. Changes in valgus rotation from 2- to 5-N·m torque were recorded as valgus gapping. Testing was then performed in 4 states: (1) native intact UCL-with dissection through skin, fascia, and muscle down to an intact UCL complex; (2) UCL-transected-distal transection of the ligament off the sublime tubercle; (3) augmented repair with bioinductive absorbable scaffold; and (4) repair alone without scaffold. The order of testing of repair states was alternated to account for possible plastic deformation during testing. RESULTS: The UCL-transected state showed the greatest increase in valgus gapping of all states at all flexion angles. Repair alone showed similar valgus gapping to that of the UCL-transected state at 30° (P = .62) and 60° of flexion (P = .11). Bioinductive absorbable scaffold-augmented repair showed less valgus gapping compared with repair alone at all flexion angles (P = .021, P = .024, and P = .024 at 30°, 60°, and 90°, respectively). Scaffold-augmented repair showed greater gapping compared with the native state at 30° (P = .021) and 90° (P = .039) but not at 60° of flexion (P = .059). There was no difference when testing augmented repair or repair alone first. CONCLUSION: UCL repair augmented with a bioinductive, biocomposite absorbable structural scaffold imparts additional biomechanical strength to UCL repair alone, without overconstraint beyond the native state. Further comparative studies are warranted. CLINICAL RELEVANCE: As augmented primary UCL repair becomes more commonly performed, use of an absorbable bioinductive scaffold may allow for improved time-zero mechanical strength, and thus more rapid rehabilitation, while avoiding long-term overconstraint or stress shielding.

Long-terms outcomes of radial head arthroplasty using a bipolar prosthesis.

BACKGROUND: In acute treatment of radial head fractures, a radial head prosthesis can be considered if open reduction and internal fixation are not technically feasible. METHODS: We reviewed the data of 27 consecutive bipolar Judet radial head prostheses implanted in patients with unreconstructable radial head fractures and no other concomitant fractures (coronoid or olecranon factures). The lesions of the lateral collateral ligament were rated according to the McKee classification. Twenty-three patients with more than ten-year follow-up participated in this retrospective study All patients underwent assessments for pain, range of motion and stability using the Mayo Elbow Performance Score, the QuickDash questionnaire and a Visual Analogue Scale for pain. Radiography assessment was performed to determine the correct setting of the implant, presence of periprosthetic loosening, prosthetic disassembly, heterotopic ossification, capitellum and ulnohumeral degenerative changes. RESULTS: Mean follow-up was 149 months (± 12.2). Mean range of motion in flexion-extension was 111° (± 10.55), mean extension was 18° (± 14.32) and mean flexion was 130° (± 11.4). Mean arc of motion in supination-pronation was 150° (± 12.26). The mean Mayo Elbow Performance Score was 88, the mean QuickDash score was 7.3; 86% of the patients were satisfied. Seven patients (26%) required secondary surgery. The most frequent complication was heterotopic ossification, which had negative consequences on the functional result. CONCLUSIONS: Bipolar radial head prostheses are an option for acute treatment of isolated unreconstructable radial head fractures. During follow-up, three patients required implant revision and removal; the capitellum surface presented severe degenerative changes and the prosthesis was not replaced. Another complication was the risk of implant dislocation, in relation to implant design, incorrect positioning of the radial head stem or else to inadequate reconstruction of the lateral collateral ligament. Further work is needed to establish the long-term follow-up results of Judet implants in complex elbow fractures.

Early range of motion results in good elbow function following conservative treatment of non-displaced radial head fractures.

INTRODUCTION: The aim of this study was to evaluate the range of motion (ROM), elbow function and predictors for good elbow function after conservative treatment of non-displaced radial head fractures. MATERIAL AND METHODS: All patients with non-displaced radial head fractures (displacement < 2 mm), that were diagnosed between January 1st 2017 and December 31st 2021 in a level I trauma center, were included in this retrospective case series and the charts were evaluated for ROM and elbow function. Elbow function was categorized as "good" or "bad" depending on the ROM measured defined by Morrey et al. Overall, 73 patients (33 male, 40 female) with an average age of 38 years (+/- 13 years) could be included. RESULTS: Conservative treatment had good clinical results for ROM and elbow function. After 6 weeks mean flexion was 131° (SD 13°), extension 8° (SD 7°), Pronation 83° (SD 11°) and Supination 83° (SD 13). Patients with a good elbow function after one week showed a good elbow function after completing the treatment. CONCLUSIONS: A clinical assessment after one week should always be performed and the study showed that it is a good predictor for good elbow function. In cases of bad elbow function further controls should be considered.

Biomechanical Assessment Methods Used in Chronic Stroke: A Scoping Review of Non-Linear Approaches.

Non-linear and dynamic systems analysis of human movement has recently become increasingly widespread with the intention of better reflecting how complexity affects the adaptability of motor systems, especially after a stroke. The main objective of this scoping review was to summarize the non-linear measures used in the analysis of kinetic, kinematic, and EMG data of human movement after stroke. PRISMA-ScR guidelines were followed, establishing the eligibility criteria, the population, the concept, and the contextual framework. The examined studies were published between 1 January 2013 and 12 April 2023, in English or Portuguese, and were indexed in the databases selected for this research: PubMed®, Web of Science®, Institute of Electrical and Electronics Engineers®, Science Direct® and Google Scholar®. In total, 14 of the 763 articles met the inclusion criteria. The non-linear measures identified included entropy (n = 11), fractal analysis (n = 1), the short-term local divergence exponent (n = 1), the maximum Floquet multiplier (n = 1), and the Lyapunov exponent (n = 1). These studies focused on different motor tasks: reaching to grasp (n = 2), reaching to point (n = 1), arm tracking (n = 2), elbow flexion (n = 5), elbow extension (n = 1), wrist and finger extension upward (lifting) (n = 1), knee extension (n = 1), and walking (n = 4). When studying the complexity of human movement in chronic post-stroke adults, entropy measures, particularly sample entropy, were preferred. Kinematic assessment was mainly performed using motion capture systems, with a focus on joint angles of the upper limbs.

Perioperative steroid injection in elbow arthroscopy.

The goal of the present study was to evaluate the incidence of infection after perioperative intra-articular steroid injection during elbow arthroscopy. Starting from May 2019, we prospectively included all patients that underwent an elbow arthroscopy for various indications. All patients received preoperative antibiotics intravenously and a corticosteroid injection immediately after portal closure. Patients who needed ligamentous repair and aged below 18 years old were excluded. Final follow up of all patients was 3 months. In total, 108 elbow arthroscopies were performed in 100 patients. No major complications and 1 minor complication were seen. One patient developed a seroma that resolved spontaneously after 14 days without intervention or antibiotics. In this patient group, a perioperative corticosteroid injection following elbow arthroscopy did not increase the chance of infection.

Does the ulnohumeral angle have a role in the aetiopathogenesis of lateral epicondylitis?

The pathophysiology of lateral epicondylitis (LE) remains not fully elucidated, as it involves a complex interaction of anatomical structures. The primary objective of the research is to identify a potential relationship between LE and the ulnohumeral angle (UHA), which demonstrates the coronal alignment of the elbow. Patients diagnosed with LE between September 1st, 2020, and September 1st, 2023, were retrospectively examined. Demographic information and UHA measurements of patients meeting the inclusion criteria and a control group with similar criteria were collected. Measurements were independently conducted by 2 orthopedists at a 2-week interval and compared. Among 413 patients meeting the inclusion criteria and the control group comprising 420 patients, there were no significant differences in age, gender, and side (P = .447, P = .288, P = .159, respectively). The mean UHA for the LE group was 13.49 ±â€…4.24, while for the control group, it was 12.82 ±â€…9.19, showing a significant difference (P = .026). The inter-observer and intraobserver reliability of the angle measurements were both above 0.80. We hypothesize that the increase in UHA in patients with LE reflects an adaptive change secondary to compressive forces acting on the lateral aspect of the elbow. This study is the first to describe the relationship between LE and UHA based on anatomical-biomechanical foundations, suggesting a cause-and-effect relationship. Further studies are warranted to delve deeper into this relationship.

Does the coronoid fracture in terrible triad injury always need to be fixed?

BACKGROUND: The ideal treatment of terrble triad injuries and whether fixation of coronoid process fractures is needed or not are still debated. Therefore, we aimed to investigate if terrible triad injuries necessitate coronoid fracture fixation and evaluate if non-fixation treatments have similar efficacies and outcomes as fixation-treatments in cases of terrible triad injuries. METHODS: From August 2011 to July 2020, 23 patients with acute terrible triad injuries without involvement of the anteromedial facet of the coronoid process were included to evaluate the postoperative clinical and radiological outcomes (minimum follow-up of 20 months). According to the preoperative height loss evaluation of the coronoid process and an intraoperative elbow stability test, seven patients underwent coronoid fracture fixation, and the other eight patients were treated conservatively. The elbow range of motion (ROM), Mayo Elbow Performance Score (MEPS), and modified Broberg-Morrey score were evaluated at the last follow-up. In addition, plain radiographs were reviewed to evaluate joint congruency, fracture union, heterotopic ossification, and the development of arthritic changes. RESULTS: At the last follow-up, the mean arcs of flexion-extension and supination-pronation values were 118.2° and 146.8° in the fixation group and 122.5° and 151.3° in the non-fixation group, respectively. The mean MEPSs were 96.4 in the fixation group (excellent, nine cases; good, tow cases) and 96.7 in the non-fixation group (excellent, ten cases; good, two cases). The mean modified Broberg-Morrey scores were 94.0 in the fixation group (excellent, sevev cases; good, four cases) and 94.0 in the non-fixation group (excellent, ten cases; good, tow cases). No statistically significant differences in clinical scores and ROM were identified between the two groups. However, the non-fixation group showed a significantly lower height loss of the coronoid process than the fixation group (36.3% versus 54.5%). CONCLUSIONS: There were no significant differences in clinical outcomes between the fixation and non-fixation groups in terrible triad injuries.

Management of Capitellar Osteochondritis Dissecans: A Critical Analysis Review.

¼ Osteochondritis dissecans of the capitellum is a localized compromise of bone that may lead to subchondral collapse with articular cartilage damage and loose body formation.¼ The etiology is multifactorial; proposed mechanisms include repetitive microtrauma, vascular insufficiency, and genetic predisposition.¼ Diagnosis is based on patient presentation, clinical examination, diagnostic imaging, and intraoperative findings.¼ Management is dependent on lesion characteristics, with stable lesions amenable to nonoperative treatment and unstable lesions managed with surgical intervention.¼ Adolescent athletes can expect a return to their preinjury level of activity or competition following indicated surgical intervention.

[OLECRANON BURSITIS].

INTRODUCTION: The olecranon bursa is a pocket-like structure located at the posterior aspect of the elbow that is responsible for the smooth movement of the surrounding tissues. Frequently, it is the source of elbow pain due to an inflammation which may be caused by local injury or penetration of bacteria through the skin. This can lead to an initial acute and possibly a late chronic inflammation. Chronic inflammation may originate from systemic diseases such as gout and rheumatoid arthritis as well. The treatment of olecranon bursitis may be conservative (non-surgical) or surgical. Recently, there is more supporting evidence for the use of conservative management over surgical intervention in treating olecranon bursitis.

Fragment excision and triceps V-Y advanced reattachment using suture anchor for olecranon nonunion: A case report.

RATIONALE: The nonunion of olecranon fractures is uncommon in simple fractures, and it is challenging to treat surgically due to the disruption of the anatomy of the elbow joint. There is limited literature on surgical options, and several factors to determine the treatment, including the amount and quality of bone stock, age, and degree of articular damage. PATIENT CONCERNS: A 58-year-old man presented at the clinic with neglected olecranon fracture for 1 year (case 1). A 74-year-old man (case 2) presented with consistent pain and limited of motion after surgery for olecranon fracture. DIAGNOSIS: Both patients were diagnosed with olecranon nonunion. INTERVENTION: Both patients received the excision of nonunited fragment and reattaching with V-Y advancement of triceps. OUTCOMES: Range of motion and Mayo elbow performance score were improved after surgery. LESSONS: This technique is useful in patients who cannot undergo other surgical options due to insufficient bone quality and elbow function, and it can lead to satisfactory outcomes with an acceptable range of motion and pain relief.

Long-standing Nonunited Fracture Lateral Humeral Condyle in Children. Evaluating a Two-stage Surgical Treatment Strategy With Critical Review.

OBJECTIVE: This work aimed to evaluate the results of using a 2-stage surgical treatment strategy without doing anterior transposition of the ulnar nerve (ATUN) for cases with long-standing nonunited fracture lateral humeral condyle (LHC) in children, accompanied by a critical review. METHODS: A consecutive 12 children with a long-standing ">2 years" nonunited LHC with evident radiologic gross anatomic distortion of the elbow were included in this study. A 2-stage surgical treatment strategy was applied, wherein the first stage, open functional reduction, osteosynthesis, and iliac bone graft were done. Then after 6 months, the second stage surgery was carried out in the form of supracondylar humeral corrective osteotomy if the cubitus valgus angle was ≥20 degrees. ATUN was not done for any of the cases even with those having ulnar nerve dysfunction. RESULTS: Union took place in 11 out of the 12 cases after a mean follow-up period of 11 weeks (range: 8 to 14 wk; SD: 1.6). All the 7 cases showed preoperative ulnar nerve dysfunction and reported clinical recovery at the end of their follow-up. CONCLUSIONS: Two-stage surgical treatment strategy without ATUN is a convenient, reproducible, and successful line of treatment for children presented with longstanding nonunited LHC with anatomically distorted elbow. LEVEL OF EVIDENCE: Level IV-case series.

Radial head replacement with the 3D-printed patient-specific titanium prosthesis: Preliminary results of a multi-centric prospective study.

PURPOSE: To report preliminary clinical results and safety of 3D-printed patient-specific titanium radial head (RH) prosthesis in treatment of the irreparable RH fractures. MATERIAL AND METHODS: This multi-centric prospective study included 10 patients (6 men and four women, mean age 41 years (range, 25-64 years)). Three cases were classified as Mason type III and 7 cases as type IV. Patients were assessed preoperatively, intraoperatively, and at 1, 6, 12, 24, 36, and 48 weeks postoperatively. Range of motion (ROM), visual analog scale (VAS) score, Disabilities of the Arm, Shoulder and Hand (DASH) score, Mayo Elbow Performance Score (MEPS), radiology imaging, and laboratory blood and urine testing were evaluated. RESULTS: The prostheses were implanted utilizing cemented stems in 5 patients and cementless stems in 5 patients. Intraoperatively, well congruency of a prosthesis with capitellum and radial notch of ulna was observed in all cases. All patients had improvement of ROM, VAS score, DASH score, and MEPS during the postoperative follow-ups. At the final follow-up, mean elbow extension was 6.5° (range, 0°-30°), flexion 145° (range, 125°-150°), supination 79° (range, 70°-80°), and pronation 73.5° (range, 45°-80°). Mean VAS score was 0.3 (range, 0-3), DASH score was 12.35 (range, 1.7-23.3), and MEPS was 99.5 (range, 95-100). Postoperative radiographs demonstrated heterotopic ossification in 2 cases, periprosthetic radiolucency in 2 cases, and proximal radial neck resorption in 2 cases. No one had the evidence of capitellar erosion, implant failure, malpositioning, overstuffing, or symptomatic stem loosening. There was no significant alteration of laboratory results or adverse events related to the 3D-printed prosthesis implantation. CONCLUSION: The preliminary results demonstrated that implantation of the 3D-printed patient-specific titanium RH prosthesis is safe and may be a potential treatment option for irreparable RH fracture.

TikTok content as a source of health education regarding epicondylitis: a content analysis.

PURPOSE: This study aimed to assess the validity and informational value of TikTok content about epicondylitis. The hypothesis tested herein was that TikTok video content would not provide adequate and valid information. METHODS: The term "epicondylitis" was used as a keyword to comprehensively search for TikTok videos, and the first 100 videos that were retrieved were subsequently included for analysis. The duration, number of likes, number of shares and number of views were recorded for each video. Furthermore, the videos were categorized on the basis of their source (medical doctor, physiotherapist, or private user), type of information (physical therapy, anatomy, clinical examination, etiopathogenesis, patient experience, treatment, or other), video content (rehabilitation, education, or patient experience/testimony), and the presence of music or voice. Assessments of video content quality and reliability were conducted using the DISCERN tool, the Journal of the American Medical Association (JAMA) benchmark criteria, and the Global Quality Score (GQS). RESULTS: A total of 100 videos were included in the analysis: 78 (78.0%) were published by physiotherapists, 18 were published by medical doctors (18.0%), and 4 were published by private users (4.0%). Most of the information pertained to physical therapy (75; 75.0%) and most of the content was about rehabilitation (75; 75.0%). The mean length of the videos was 42.51 ± 24.75 seconds; the mean number of views was 193,207.78 ± 1,300,853.86; and the mean number of comments, likes, and shares were 22.43 ± 62.54, 1578.52 ± 8333.11, and 149.87 ± 577.73, respectively. The mean DISCERN score, JAMA score, and GQS were 18.12 ± 5.73, 0.80 ± 0.53, and 1.30 ± 0.52, respectively. Videos posted by medical doctors/private users had higher scores (p < 0.05) than videos posted by physiotherapists. Videos that focused on education or patient experience had higher scores (p < 0.05) than videos based on rehabilitation. CONCLUSIONS: TikTok can be an unreliable source of information regarding epicondylitis treatment. It is common to find nonphysicians who share medical advice on the platform, with medical treatments demonstrating the weakest level of supporting evidence. Elbow surgeons should advise their patients that treatment recommendations from TikTok may not align with established guidelines. LEVEL OF EVIDENCE: Level IV-Cross-sectional study.

[A multicenter clinical study on the treatment of lateral epicondylitis of humerus by manipulation].

OBJECTIVE: To investigate clinical effect of tendons pulling,poking and kneading for the treatment of external humeral epicondylitis.

There were 96 patients in treatment group,including 36 males and 60 females,aged from 28 to 60 years old with an average of (41.20±5.50) years old;the course of disease ranged from 1 to 14 days with an average of (5.24±1.35) days;they were treated once every other day for 2 weeks. There were 96 patients in control group ,including 33 males and 63 females,aged from 26 to 60 years old with an average of (43.35±7.75) years old;the course of disease ranged from 1 to 14 days with an average of (5.86±1.48) days;they were treated with topical voltaalin combined with elbow joint fixation for 2 weeks. Visual analogue scale (VAS) and Hospital for Surgery Scoring System (HSS) elbow pronation and supination angles,wrist metacarpal flexion and dorsal extension angles,elbow tenderness between two groups were compared before treatment and at 1,3,5,7,11 and 13 days after treatment;Hospital for Surgery Scoring System 2 (HSS2) was compared before treatment and the final treatment. RESULTS: All patients were followed up for 10 to 14 days with an average of (12±1.6) days. VAS between treatment group and control group before treatment were 6.83±1.36 and 6.79±1.58,respectively,and decreased to 1.49±1.09 and 2.11±1.81 after the final treatment. VAS of treatment group were significantly lower than those of control group at 1,3,5,7,9,11 and 13 days after treatment (P<0.05). HSS between two groups were 61.73±11.00 and 36.47±12.45 before treatment,respectively,and increased to 94.42±5.9 and 91.44±9.11 at the final treatment. HSS of treatment group were significantly higher than those of control group at 1,3,5,7,9,11 and 13 days after treatment (P<0.05). On the 5th day after treatment,the external and internal rotation angles of elbow in treatment group were (66.41±12.69) ° and (66.35±13.54) °,while those in control group were (62.08±16.03) ° and (61.77±16.35) °. On the 7th day after treatment,the external and internal rotation angles of elbow were (69.79±12.64) ° and (70.02±13.55) ° in treatment group,and (65.28±15.86) ° and (65.09±16.67) ° in control group. Elbow joint motion in treatment group was higher than that in control group (P<0.05). On the 5th day after treatment,angles of wrist dorsiflexion and palm flexion were (39.43±15.94) ° and (46.68±11.10) ° in treatment group,and (38.51±18.49) ° and (44.27±13.58) ° in control group. On the 7th day after treatment,angles of wrist dorsiflexion and palm flexion were (42.52±16.50) ° and (49.23±10.96) ° in treatment group,and (41.18±20.09) ° and (46.64±14.63) ° in control group. The motion of wrist joint in treatment group was higher than that in control group (P<0.05). On the 13th day after treatment,HSS2 in treatment group 93.61±6.32 were higher than those in control group 92.06±7.94(P<0.05). There was no significant difference in elbow tenderness between two groups at each time point (P>0.05). CONCLUSION: Voltaren external treatment combined with elbow fixation and tendons pulling,poking and kneading could effectively improve symptoms of external humeral epicondylitis. Compared with voltaren external treatment,tendons pulling,poking and kneading has advantages of longer analgesic time and better elbow function recovery.

Treatment of Adult Distal Humerus Fracture with Fishtail Deformity: A Case Report.

CASE: We report a single case of a closed intra-articular distal humerus fracture in a 28-year-old man with a preexisting fishtail deformity characterized by concavity of the central trochlea and corresponding deformity of the olecranon. The patient was treated with open reduction and internal fixation. CONCLUSION: The case highlights the diagnosis and challenges of treatment. Conventional fixation choices and imaging techniques may need to be altered when treating a fracture with this deformity.
