Triceps skinfold thickness trajectories and the risk of all-cause mortality:A prospective cohort study

BACKGROUND The measurement of triceps skinfold(TSF)thickness serves as a noninvasive metric for evaluating subcutaneous fat distribution.Despite its clinical utility,the TSF thickness trajectories and their correlation with overall mortality have not been thoroughly investigated.AIM To explore TSF thickness trajectories of Chinese adults and to examine their associations with all-cause mortality.METHODS This study encompassed a cohort of 14747 adults sourced from the China Health and Nutrition Survey.Latent class trajectory modeling was employed to identify distinct trajectories of TSF thickness.Subjects were classified into subgroups reflective of their respective TSF thickness trajectory.We utilized multivariate Cox regression analyses and mediation examinations to explore the link between TSF thickness trajectory and overall mortality,including contributory factors.RESULTS Upon adjustment for multiple confounding factors,we discerned that males in the‘Class 2:Thin-stable’and‘Class 3:Thin-moderate’TSF thickness trajectories exhibited a markedly reduced risk of mortality from all causes in comparison to the‘Class 1:Extremely thin’subgroup.In the mediation analyses,the Geriatric Nutritional Risk Index was found to be a partial intermediary in the relationship between TSF thickness trajectories and mortality.For females,a lower TSF thickness pattern was significantly predictive of elevated all-cause mortality risk exclusively within the non-elderly cohort.CONCLUSION In males and non-elderly females,lower TSF thickness trajectories are significantly predictive of heightened mortality risk,independent of single-point TSF thickness,body mass index,and waist circumference.

Bilateral snapping triceps syndrome:A case report

BACKGROUND Snapping triceps syndrome(STS)is a rare disease,while occurrence of bilateral STS is extremely rare.It is usually accompanied by dislocation of the ulnar nerve and double snapping is a clinically important feature.However,to the best of our knowledge,there has been no report of bilateral STS in young active patient.CASE SUMMARY A 23-year-old male presented with a complaint of discomfort and snapping on the medial side of both elbows while performing push-ups.On physical examination,two distinct snaps that were both palpable and audible were detected on additional clinical examination.Dynamic ultrasonography showed that the ulnar nerve and the medial head of the triceps were dislocated anteriorly over the medial epicondyle of the elbow during flexion motion.Finally,he was diagnosed as dislocation of the ulnar nerve and STS.Staged anterior subcutaneous transposition of the ulnar nerve combined with partial resection of the snapping portion of the triceps was performed.The patient’s pain and snapping symptoms were resolved immediately after surgery.Three months later,the patient was completely asymptomatic and returned to normal activity.CONCLUSION STS should be included in the differential diagnosis for active young patients who present with painful snapping on the medial side of the elbow joint,particularly when dislocation of the ulnar nerve is detected.Dynamic sonography is used to assist in accurate diagnosis and differentiation between isolated dislocation of the ulnar nerve and STS.

Distal triceps injuries(including snapping triceps):A systematic review of the literature

AIM To review current literature on types of distal triceps injuryand determine diagnosis and appropriate management.METHODS We performed a systematic review in PubM ed, Cochrane and EMBASE using the terms distal triceps tears and snapping triceps on the 10 th January 2017. We excluded all animal, review, foreign language and repeat papers. We reviewed all papers for relevance and of the papers left we were able to establish the types of distal triceps injury, how these injuries are diagnosed and investigated and the types of management of these injuries including surgical. The results are then presented in a review paper format.RESULTS Three hundred and seventy-nine papers were identified of which 65 were relevant to distal triceps injuries. After exclusion we had 47 appropriate papers. The papers highlighted 2 main distal triceps injuries: Distal triceps tears and snapping triceps. Triceps tear are more common in males than females occurring in the 4th-5th decade of life and often due to a direct trauma but are also strongly associated with weightlifting and American football. The tears are diagnosed by history and clinically with a palpable gap. Diagnosis can be confirmed with the use of ultrasound(US) and magnetic resonance imaging. Treatment depends on type of tear. Partial tears can be treated conservatively with bracing and physio whereas acute tears need repair either open or arthroscopic using suture anchor or bone tunnel techniques with similar success. Chronic tears often need augmenting with tendon allograft or autograft. Snapping triceps are also seen more in men than women but at a mean age of 32 years. They are characterized by a snapping sensation mostly medially and can be associated with ulna nerve subluxation and ulna nerve symptoms. US is the diagnostic modality of choice due to its dynamic nature and to differentiate between snapping triceps tendon or ulna nerve. Treatment is conservative initially with activity avoidance and if that fails surgical management includes resection of triceps edge or transposition of the tendon plus or minusulna nerve transposition.CONCLUSION Distal triceps injuries are uncommon. This systematic review examines the evidence base behind diagnosis, imaging and treatment options of distal triceps injuries including tears and snapping triceps.

Treatment of talipes equinovarus after triceps surae intramuscular hemangioma surgery by Ilizarov technology in adults:A case report

BACKGROUND Postoperative complications of triceps surae intramuscular hemangioma surgery with talipes equinovarus have rarely been described,and the evidence for treatment is limited.The purpose of this case study was to report the new application of the Ilizarov technique,which successfully treated talipes equinovarus in adults after triceps surae intramuscular hemangioma.CASE SUMMARY A 29-year-old woman treated with the Ilizarov technique for talipes equinovarus in the right leg after triceps surae intramuscular hemangioma surgery.The equinus deformity was roughly corrected after 2 years of follow-up,without significant secondary sequelae.CONCLUSION Talipes equinovarus caused by postoperative sequelae of intramuscular hemangioma was successfully corrected by the Ilizarov technique.The Ilizarov technique may be used for treating talipes equinovarus caused by various causes.

Functional Outcomes after Triceps Splitting versus Triceps Sparing Approach for Extra-Articular Distal Humerus Fractures

Aim: To compare the functional outcome as well as elbow range of motion (ROM) after triceps splitting and triceps sparing approach for AO/OTA TYPE A distal humerus fractures. Materials and Methods: This is a prospective study done at our center between 2011 and 2014. A total of 50 patients presented with extra articular distal humerus fracture (AO/OTA 13 A2, 13A3). Exclusion criteria removed 16 patients from the study while 2 patients died due to medical comorbidities before the final follow up. Out of the remaining 32 patients, they were divided into two groups: triceps splitting (15 patients) and triceps sparing (17 patients). Elbow ROM, along with Disabilities of the Arm, Shoulder and Hand questionnaire scores, was compared between the two groups. Results: Triceps sparing group had greater elbow flexion (140.0 ± 4.0) compared to triceps splitting group (126.0 ± 10.0) with p Conclusion: As compared to triceps splitting approach, triceps sparing approach results in better elbow ROM with less extension contracture, however both approaches result in similar functional outcome.

Triceps Brachii Tendon Reconstruction with V-Y Plasty: Indication and Functional Results of a Case at BouakéTeaching Hospital

Repair of an old lesion of the triceps brachii tendon is infrequent. A V-Y plasty was performed 4 years after the injury in an adult. Post traumatic osteoarthritis limits functional outcomes. The patient is satisfied.

Treatment of Neglected Elbow Dislocations by Z-Lengthening of the Triceps Brachii

Introduction: Neglected elbow dislocations are much more common in developing and underdeveloped countries. The main reason for the delay in diagnosis is that patients initially seek treatment from traditional healers. These will immobilize the elbow in extension, which will lead to the retraction of the triceps muscle and collateral ligaments. Patients and Method: We carried out a prospective study over five years (2014-2019). The study involved patients with unreduced elbow dislocation older than 21 days. All patients with a dislocated fracture and those whose x-ray showed joint fusion were not included in the study. We collected 26 patients, 20 men and 6 women with an average age of 27.5 years (17 and 45 years). The average consultation time was 8.9 months (3 - 13). The approach was posterior about 8 cm above the olecranon and 2 cm below the olecranon, the ulnar nerve was identified and isolated. The triceps tendon was cut in a Z from its myotendin junction to the beak of the olecranon, and then lengthened. Results: The patients were reviewed after a mean follow-up of 24 months (12 - 36). The Mayo Clinic’s average elbow performance index was 77.1 (60 - 85), with 19 good and 6 average results. The mean flexion was 114°(100°- 135°) and the mean extension deficit was 31.15°(10°- 55°). The average range of motion was 82.5°(60°- 120°). We did not find a correlation between the duration of the lesion and functional recovery (p > 0.05). The Wilcoxon test showed that surgery significantly improved the overall range of motion of the elbow (p = 0.001). Discussion: Based on this study, open reduction with tendon lengthening should remain a treatment option regardless of the age and chronicity of the dislocation.

A clinicoradiological classification and a treatment algorithm for traumatic triceps tendon avulsion in adults

Triceps tendon avulsion(TTA)is an uncommon injury,and there are no classifications or treatment guidelines available.This study aims to describe a clinicoradiological classification and treatment algorithm for traumatic TTA in adults.The functional outcome of surgical repair has been evaluated too.;A retrospective analysis of adult patients with traumatic TTA treated in our institution between 2012 and 2017 was done.We only included complete TTA injuries.Children below 15 years,open injuries,associated fractures,and partial TTA were excluded.The data were obtained from hospital records.The intraoperative findings were correlated with the clinicoradiological presentation for classifying TTA.The functional outcome was analyzed using the Mayo Elbow Performance index and Hospital for Special Surgery elbow score.ANOVA test was used to assess the statistical significance.;There were 15 patients included,including 11 males and 4 females.The mean age was(31.5±9.15)years,and the mean follow-up was(22.4±8.4)months.Fall on outstretched hand was the mode of injury.In 6 patients,diagnosis was missed on the initial visit.TTA were classified as Type 1:palpable soft-tissue defect without bony mass;Type 2:palpable soft-tissue defect with a wafer-thin/comminuted bony fragment on X-ray;Type 3:palpable soft-tissue defect with a bony mass and a large bony fragment on X-ray without extension to the articular surface;and Type 4:an olecranon fracture with less than 25%of the articular surface.An algorithm for treatment was recommended,i.e.transosseous suture repair/suture anchor for Type 1,transosseous suture repair for Type 2,and tension band wiring or steel wire sutures for Types 3 and 4.All the patients achieved good to excellent outcome:the mean Mayo Elbow Performance index was 100 and Hospital for Special Surgery score was 98.26±2.60 on final follow-up.;Our clinicoradiological classification and treatment algorithm for TTAs is simple.Surgical treatment results in excellent functions of the elbow.Since it is a single-center study involving a very small number of cases,a multicenter study with a larger number of patients is required for external validation of our classification and treatment recommendations.

Bilateral triceps tendon approach is flexible and efficient in the treatment of type C distal humerus fractures

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(00).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 00.Methods:Patients treated with 00 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 00 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 00 were included in this study.There were 10 fractures of type Cl,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 00 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 00.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 00 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 00.BTT were not suitable for every case with severe comminuted pattern,but it avoids the potential complications related to 00,and has no complications concerning with triceps tendon.It is convenient for open reduction internal fixation and flexible to be converted to 00,as well as available to be converted to TEA in elder patients.

Rupture of the triceps tendon - A case series

Triceps rupture is the least common among all tendon injuries. The usual mechanism of injury is a fall on an outstretched hand, although direct contact injuries have also been reported to cause this injury. The diagnosis of acute triceps tendon rupture may be missed, which can result in prolonged disability and delayed operative management. We presented three cases of acute triceps tendon rupture each at different site showing the spectrum of injury to the muscle and mechanism of injury and management were also discussed.

Effect of a 10-Week Stretching Program of the Triceps Surae Muscle Architecture and Tendon Mechanical Properties

Purpose The present study aimed to test if a long-term passive stretching training causes adaptations of the medial gastroc-nemius architecture and the Achilles tendon (AT) tangent modulus.Methods A total of 20 males took part in the study.The stretching group (n =12),performed stretching exercises for the plantar flexors for 10 weeks,4-5 times a week,which comprised two static positions sustained twice each during 30 s.Results For the stretching group,maximum dorsiflexion angle,peak passive torque,and muscle-tendon unit maximum length significantly increased after training.No other differences were found related to muscle architecture and AT tangent modulus.Conclusion Joint amplitude gain after a long-term stretching of the triceps surae was not accompanied by structural or mechanical changes of the medial gastrocnemius and AT tendon,and seems to reflect an increasing stretch tolerance level.
