Traumatic avulsion of the subscapularis tendon in adolescents: Return to sport after surgical repair.

INTRODUCTION: Traumatic complete rotator cuff tears are rare in the pediatric population. These injuries might be a result of shoulder dislocation or direct trauma experienced during contact sports (i.e., rugby, judo). The purpose of this study was to identify the epidemiologic and clinical characteristics of these injuries and assess the medium- and long-term outcomes following surgery, with return to sport as the primary endpoint. MATERIALS AND METHODS: An electronic questionnaire was sent to all surgeons who were members of the French Shoulder and Elbow Society (SOFEC) and/or the French Society of Arthroscopy (SFA), asking if they ever had to surgically treat a traumatic complete tear of 1 or more rotator cuff tendons in a child or adolescent. Ninety (38.6%) of the 233 surgeons members of the SOFEC and/or the SFA responded to our questionnaire. We then contacted the 15 surgeons who answered affirmatively to collect the complete medical records of their patient(s). RESULTS: We reviewed the records of 17 children and adolescents who underwent surgery for a traumatic complete rotator cuff tear. The mean age at surgery was 15.2 years (range, 12-17). Glenohumeral dislocation during contact sports (n=7/17) was a frequent mechanism of injury (41%). All of these cases involved at least the subscapularis muscle with an avulsed bony insertion. The injury involved other rotator cuff tendons in 29% of cases (5/17). The bone and tendon repair was either performed as open surgery (n=5/17) or arthroscopically (n=12/17). At a median follow-up of 24 months and a mean follow-up of 50 months, 82.4% of patients had returned to sport at their preinjury level. Three patients presented neurologic complications resulting from the traumatic event, but only 1 of them required nerve grafting with a favorable outcome. We also reported 3 cases of nonunion of the lesser tuberosity that required revision surgery with good outcomes. Only 1 patient out of all those with at least 1 episode of dislocation presented a recurrent anterior shoulder instability that required a bone block-type procedure 7 years after the initial surgery. CONCLUSION: Traumatic complete rotator cuff tears are rare in children and adolescents. They often occur during contact sports. These types of injuries are diagnosed by clinical examination and confirmed by cross-sectional imaging, ideally magnetic resonance imaging. Tendon injuries mainly involve the subscapularis but can also affect other cuff tendons. Return to preinjury activity levels after surgical management was possible in more than 80% of cases.

Nonliving versus Living Animal Models for Microvascular Surgery Training: A Randomized Comparative Study.

BACKGROUND: Ethical and financial considerations have encouraged the use of nonliving models for simulation-based training in microsurgery, such as commercially available chicken thighs. The purpose of this study was to compare the nonliving chicken thigh model to the one currently considered as the standard-namely, the living rat model-in the setting of an initiation microsurgery course. METHODS: Applicants to the 3-day basic microsurgery course of the Paris School of Surgery were assigned randomly to either one group that received the regular training of the school (RT group), including four hands-on sessions using only living rat models, or one group that received a modified curriculum in which a nonliving chicken thigh model was used for the first hands-on session (CT group). During the following session, all trainees were evaluated on living rat models, using a global rating scale and two task-specific scales (knot-tying and anastomosis); rates of anastomosis patency, animal survival, and technique completion were recorded. RESULTS: Ninety-three residents were enrolled. Global rating scale, knot-tying, and anastomosis task-specific scale scores were significantly higher in the CT group ( n = 51) than in the RT group, with mean differences of 2.6 points ( P = 0.0001), 1.3 points ( P < 0.0001), and 1.4 points ( P < 0.0001), respectively. Patency and survival rates were significantly higher in the CT group than in the RT group, with mean differences of 22% ( P = 0.0020) and 27% ( P < 0.0001), respectively; completion rates were not statistically different. CONCLUSION: Subject to the use of validated models, such as the chicken thigh, nonliving animal models are a suitable alternative to the living rat model in microsurgery initial training. CLINICAL RELEVANCE STATEMENT: The use of validated non-living models, such as the chicken thigh, is a suitable alternative to the living rat model in microsurgery initial training.

"Unhappy triad" of the trauma elbow in children: Diagnosis, classification, and mid-term outcomes.

Background: The aim of this study was to describe the epidemiology, physiopathology, and outcomes of elbow "unhappy triad" trauma in children, combining a posterior dislocation, a proximal radius fracture, and a third lesion (i.e. bony or capsuloligamentous injury). Methods: A retrospective bicentric study was conducted between 1999 and 2020. All skeletally immature children who presented to the emergency department and underwent surgery for a proximal radius injury were selected. Among this selection, only patients with two associated ipsilateral elbow injuries (i.e. posterior elbow dislocation and a bony and/or capsuloligamentous injury) were included. Active elbow ranges of motion, Mayo Elbow Performance Score and Quick-Disabilities Of The Arm, Shoulder And Hand scores and standard radiographs were recorded at last follow-up. Results: Twenty-one patients met the inclusion criteria (mean age at surgery = 11.4 years) among 737 selected. The "unhappy triad" diagnosis was made preoperatively in nine cases (bone lesion only), intraoperatively in nine cases, and postoperatively in one case. The third lesions were surgically treated when the lesion was a bony fracture or if the elbow remains unstable between 60° and 90° of flexion (i.e. capsuloligamentous injury). Twenty patients were reviewed (mean follow-up = 5.8 years). The complications and re-operations rates were of 10%. Conclusion: The "unhappy" triad of the child's elbow is a rare injury, where the preoperative diagnosis is frequently missed and lead to 10% of complications and re-operations. Level of evidence: level III.

Validation of the French version of the Caregivers' Priorities and Child Health Index of Life with Disabilities questionnaire.

INTRODUCTION: The Caregivers' Priorities and Child Health Index of Life with Disabilities (CPCHILD) is a questionnaire that measures the health-related quality of life (HRQL) of children with cerebral palsy (CP). Though measuring HRQL is challenging in these children, it is a valuable help for medical decision-making. There is no questionnaire to assess HRQL in French-speaking children with severe CP. OBJECTIVE: To translate and adapt transculturally the CPCHILD questionnaire into French (CPCHILD-FV). MATERIAL AND METHODS: The CPCHILD was translated from English into French by forward and backward translation by independents translators. The questionnaire was then tested on 32 caregivers of patients with CP classified as GMFCS IV or V, remarks of caregivers were analyzed by an expert committee and, if necessary, modifications were performed. Internal consistency of the CPCHILD-FV was assessed using a sample of 32 parents or caregivers and test-retest reliability was assessed on a random sample of 10 patients. RESULTS: The translation and transcultural process resulted in a French version of the CPCHILD. Some items of the CPCHILD required careful discussion to ensure that items had the same meaning as in the original. Internal consistencies were over 0.70 for each domain except for health, and 0.97 for the total scores. The ICC for the test-retest reliability of the CHILD-FV total score was 0.98 (95% CI: 0.93-0.99) and ranged from 0.59 to 0.99 for the domains. CONCLUSION: The translation and cross-cultural adaptation of the CPCHILD questionnaire provides a French version than can measure the HRQL of children with severe CP. LEVEL OF EVIDENCE: IV; prospective study without control group.

Age Influence Upon Glenohumeral Remodeling After Shoulder Axial Rebalancing Surgery in Brachial Plexus Birth Injury.

BACKGROUND: Shoulder rebalancing procedures have been proven to provide satisfactory functional improvements in patients with shoulder external rotation (ER) deficit due to brachial plexus birth injury (BPBI). However, the influence of age at the time of surgery on osteoarticular remodeling remains uncertain. The purposes of this retrospective case series were (1) to assess the age impact on glenohumeral remodeling and (2) to determine an age limit after which significant changes can no longer be expected. METHODS: We reviewed preoperative and postoperative magnetic resonance imaging data of 49 children with BPBI who underwent a tendon transfer to reanimate active shoulder ER, with (n=41) or without (n=8) concomitant anterior shoulder release to restore passive shoulder ER, at a mean age of 72 ± 40 months (19;172). Mean radiographic follow-up was 35 ± 20 months (12;95). Univariate linear regressions were used to assess the influence of age at the time of surgery upon changes of glenoid version, glenoid shape, percentage of the humeral head anterior to the glenoid midline, and glenohumeral deformity. Beta coefficients with 95% CI were calculated. RESULTS: Improvements of glenoid version, glenoid shape, percentage of the humeral head anterior and glenohumeral deformity significantly decreased by 0.19 degrees [CI=(-0.31; -0.06), P =0.0046], 0.02 grade [CI=(-0.04; -0.01), P =0.002], 0.12% [CI=(-0.21; -0.04), P =0.0076], and 0.01 grade [CI=(-0.02; -0.01), P =0.0078] per additional month of age at the time of surgery, respectively. The threshold of 5 years was identified as the age at the time of surgery after which significant remodeling no longer occurred. No significant postoperative changes were observed in patients without glenohumeral dysplasia on preoperative magnetic resonance imaging. CONCLUSION: In the setting of BPBI-related glenohumeral dysplasia, the younger the surgical axial rebalancing of the shoulder, the greater the glenohumeral remodeling seems to be. Such procedure seems to be safe in patients without significant joint deformity on preoperative imaging. LEVEL OF EVIDENCE: Therapeutic-Level IV.

Dynamic pediatric shoulder instability: Etiology, pathogenesis and treatment.

Dynamic shoulder instability in children or adolescents, whose glenohumeral growth plates are still open, is a rare condition with an etiology that is hard to decipher. Atraumatic and recurrent forms are most common, contrary to adults. Disruptions to capsule and ligament maturation, muscle balance or bone growth can lead to glenohumeral instability. The etiology assessment, which needs to be multidisciplinary in atraumatic forms, aims to collect the medical history, analyze the direction of the instability, determine whether it is voluntary or involuntary, and look for a history of trauma, connective tissue abnormality, psychological disorder, neuromuscular pathology or congenital malformation. The initial treatment is conservative. It requires a multidisciplinary team when the shoulder instability is voluntary. Surgical treatment is reserved for symptomatic forms that do not respond to conservative treatment and have an impact on daily life and/or sports participation after a minimum of 6 months of well-conducted rehabilitation. The results of surgical stabilization mainly depend on the features of the instability, the anatomical structures damaged and the etiology. Episodes of recurrent instability in children/adolescents with open glenohumeral growth plates can fade in adulthood or can get worse with the development of structural damage. Early detection of poor outcomes and suitable treatment will help to limit the occurrence of osteoarthritis in the medium and long term. LEVEL OF EVIDENCE: Expert opinion.

Do web-based follow-up surveys have a better response rate than traditional paper-based questionnaires following outpatient arthroscopic rotator cuff repair? A randomized controlled trial.

INTRODUCTION: Considering the extensive use of smartphones in current societies, web-based applications could be considered as a new option for patient follow-up in surgery. By means of such tool, automated and periodic questionnaires could improve the rigor, accuracy and the comprehensiveness of postoperative monitoring, as well as early detection of complications, especially in the current context of evolving ambulatory surgery. HYPOTHESIS: The web-based surveys would improve the quality of immediate postoperative monitoring. MATERIAL AND METHODS: For 7 months, we included all patients who underwent outpatient arthroscopic rotator cuff repair. After preoperative randomization, each patient was asked postoperatively to complete either paper-based forms or digital questionnaires via a website (Orthense.com®, Digikare Inc. Blagnac, France). Both media (i.e. paper and digital) followed the same postoperative agenda (i.e., D+3, D+14, D+28, D+45, D+90) and had the same content, including pain and discomfort assessments, functional scores (i.e. Shoulder subjective value, simple shoulder test and auto-constant scores). The main objective was to investigate the quality of postoperative follow-up after outpatient arthroscopic rotator cuff surgery, using either printed questionnaires or web-based surveys. The hypothesis was that using a web-based survey would result in greater response rates and increased patient satisfaction regarding follow-up. Primary outcomes were questionnaire response rates at D+45 and D+90, while secondary outcomes were overall response rates, patient recommendation for the monitoring medium and overall patient satisfaction regarding their follow-up using the net promoter score (NPS). RESULTS: Among the 59 consecutive patients who were included, there were 27 females and 26 males with a mean age of 57±10.2 years; 27 patients completed the web-based survey (Group A) and 26 patients answered paper-based questionnaires (Group B). Regarding the D+45 questionnaire, response rates were 85.2% (n=23) in group A and 42.3% (n=11) in group B (p=.005); a similar significant difference was observed regarding the D+90 questionnaire, with response rates of 70.4% and 34.6%, respectively (p=.027). The mean NPS for the survey was 10 in Group A and 8.29 in Group B (p=.016). Overall, satisfaction regarding postoperative care did not differ between the two groups. DISCUSSION: Compared to traditional paper-based forms, web-based surveys appear to increase patient adherence to short-term postoperative monitoring. If these findings were to be confirmed in long-term follow-up, such straightforward and cost-effective tool could be of great use in clinical care and research. LEVEL OF EVIDENCE: I; Randomized controlled clinical trial.

Stemless Shoulder Arthroplasty.

Stemless humeral components for shoulder arthroplasty represent the fourth generation of modern prosthetic shoulder implants. Because of their metaphyseal fixation, the implantation technique is rather straightforward and preserves the humeral canal from violation. Substantial benefits have been highlighted with such a design, including less perioperative morbidity, independence from the proximal humeral anatomy, preservation of bone stock, ease of potential revision surgeries, and limited risk of complex periprosthetic fractures. Initially conceived to better re-create the center of rotation of the humeral head in anatomic arthroplasties, their use has been successfully extended to reverse total shoulder arthroplasty. Provided that contraindications are respected (eg, poor proximal humeral bone quality, proximal humerus fractures, patients who are elderly and/or overweight), short-term and midterm functional outcomes as well as postoperative complications appear to be similar to those of traditional stemmed implants, without increased risk of loosening of the humeral component.

3D planning and patient-specific surgical guides in forearm osteotomy in children: Radiographic accuracy and clinical morbidity.

INTRODUCTION: Three-dimensional (3D) planning and patient-specific surgical guides are increasingly used in the treatment of skeletal deformities. The present study hypothesis was that they are reliable in forearm osteotomy in children, with low morbidity. MATERIAL AND METHODS: Twenty-there children with one or several osteotomies to correct forearm deformities were retrospectively included: 9 (20 osteotomies) with surgical guide (G+), and 14 (28 osteotomies) without (G-). Etiologies comprised 8 cases of Madelung disease (3G+, 5G-) and 15 of post-traumatic malunion (6G+, 9G-). Mean age at surgery was 14.8±1.9 years. The patient-specific 3D-printed polyamide guides were produced from 3D virtual models based on 3D CT reconstruction. Mean follow-up was 22.1±13.6 months. RESULTS: Mean correction error was 5.3°±4.1 and 4.2°±4.1 in the frontal and sagittal planes respectively in G+ (p=0.6). Surgery time was significantly shorter in G+, by a mean 42min (p=0.02). Mean total radiation dose (preoperative CT+intraoperative fluoroscopy) was significantly higher in G+ (p<0.0001). Complications rates were similar between groups. Improvement in PRWE score was significantly greater in G+. CONCLUSION: The present preliminary results were encouraging. 3D planning and patient-specific surgical guides can be used in the treatment of forearm deformity in children.

Use of an external fixator during one-step surgical management of missed chronic Monteggia injuries.

The incidence of untreated Monteggia fracture-dislocations is not insignificant. But there is no consensus as to the surgical indication and best surgical technique to use. Single-stage reduction of the radial head through an elbow arthrotomy and ulnar osteotomy is a complex surgical procedure that requires stabilization of the ulnar segments during every step of the intervention. Here, we describe the possibility of using an external fixator intraoperatively to facilitate the various steps of the procedure: (1) gradual distraction and angulation of the osteotomy site to allow thorough excision of any interposed capsular tissue, (2) stable hold on the ulnar fragments independent of the surgical assistant, which allows the stability of the radial head reduction to be tested in pronation and supination and (3) facilitation of plate fixation at the ulnar osteotomy site. LEVEL OF EVIDENCE: IV; case series.

Histopathological nerve assessment in brachial plexus birth injuries.

In children suffering from brachial plexus birth injuries (BPBI), one major difficulty concerns intraoperative selection of the roots to be used for reconstruction. Between November 2018 and August 2020, surgical qualitative evaluations and pathological quantitative analyses were conducted on 52 roots and 29 distal neural stumps (trunks, divisions, cords, and nerves distal to the neuroma) in 17 patients who underwent brachial plexus reconstruction. For each root, surgeons rated stump quality as "good", "fair" or "avulsed". Neural sections were then sent to pathology to determine percentage intraneural fibrosis under microscopy. Mean root intraneural fibrosis rates were 30.5% (SD 24.9; range, 0-80%), 46.3% (SD 32.6; range, 0-90%) and 24.6% (SD 23.5; range, 0-80%) in the "good quality", "fair quality" and "avulsed" groups, respectively, with no significant differences between groups. In distal neural stumps, the mean intraneural fibrosis rate was 30.9% (SD 24.7). These findings raise the question of conducting frozen section biopsy of neural stumps after neuroma resection to determine surgical reconstruction strategy.

Epidemiology of hand traumas during the COVID-19 confinement period.

INTRODUCTION: hand injuries are a common emergency mainly caused by domestic accidents or sport injuries. During the COVID-19 pandemic confinement period, with a cut off in transportation as well as in occupational and physical activities, we observed a decrease in medical and elective surgical activities but emergency cases of upper limb and hand surgery increased. MATERIALS AND METHODS: we conducted a retrospective epidemiological study to analyze two periods between the same dates in 2019 and 2020, for all the duration of the confinement period. We compared the numbers of consultations in the emergency department, elective surgeries, hand and upper limb emergency cases in our center and urgent limb surgeries in the nearby hospital. Then we compared the mechanisms and severity of injuries and the type of surgery. RESULTS: between 2019 and 2020 there was a decrease of consultations in the emergency department in our institution of 52%, a decrease of total elective surgeries of 75%, a decrease in surgeries for urgent peripheral limb injuries of 50%, whereas the hand and upper limb emergency remained stable or even increased by 4% regard to occupational and domestic accidents. There was a significant difference in the mechanism of injury with an increase of domestic accident and a decrease of occupational, road traffic and sport accidents. Severity of the injuries increased, with augmentation of the number of tissues involved and longer expected time of recovery. CONCLUSION: during the confinement period of the COVID-19 pandemic, despite an important reduction of medical activities, the amount and severity of hand emergency cases increased. A specific plan regarding duty shift organization for hand trauma should be maintained regardless of the sanitary situation.

Shoulder internal rotation contracture in brachial plexus birth injury: proximal or distal subscapularis release?

BACKGROUND: In cases of brachial plexus birth injury with internal rotation contracture of the shoulder, the subscapularis muscle may be released proximally, from the subscapular fossa, or distally, along with periarticular soft tissues arthroscopic to the glenohumeral joint. We hypothesized that the indication for each procedure would rely primarily on patients' bone remodeling potential and periarticular soft-tissue contractures, performing proximal releases in patients aged < 4 years and periarticular distal releases in older patients. The purpose of this study was to analyze the outcomes such a strategy could provide. METHODS: All patients presenting with brachial plexus birth injury-related shoulder internal rotation contractures who underwent a subscapularis release were included; in addition, to restore the joint axial balance, the infraspinatus was systematically reanimated with a tendon transfer (ie, latissimus dorsi or lower trapezius) during the same operating time. Chart review yielded preoperative and postoperative clinical and radiographic measurements, including active and passive range of motion of the shoulder in external rotation (ER) with the arm at the side of the body, the modified Mallet score, glenoid version, and the percentage of the humeral head arthroscopic to the middle of the glenoid process. RESULTS: Between July 2012 and January 2018, 28 children were operated on at our institution. In patients who underwent proximal subscapularis release (n = 13), significant improvements were observed regarding active shoulder ER, passive shoulder ER, the modified Mallet score, glenoid version, and the percentage of the humeral head arthroscopic to the middle of the glenoid process, averaging 58° ± 32° (P < .0001), 56° ± 20° (P < .0001), 9.7 ± 3.1 points (P = .0006), 15° ± 10° (P = .0034), and 24% ± 20% (P = .0113), respectively, after a mean follow-up period of 4 years. Following distal release procedures (n = 15), these improvements averaged 26° ± 29° (P = .0024), 27° ± 28° (P = .0011), 3.3 ± 4.1 points (P = .0049), 2° ± 17° (P = .4086), and 4% ± 18% (P = .215), respectively, after a mean follow-up period of 3 years. CONCLUSION: When combined with axial rebalancing of the joint, the proximal release of the subscapularis muscle appears to be sufficient to provide satisfactory functional outcomes in patients with great bone remodeling potential and supple periarticular soft tissues. In older patients, a more comprehensive release of the glenohumeral joint's arthroscopic aspect seems to provide lower but still significant clinical improvements.

Radial neck fractures in children secondary to horse-riding accidents: a comparative study.

INTRODUCTION: In the pediatric population, fractures of the radial neck account for approximately 1% of all fractures and can have substantial consequences. Given the growing popularity of horse riding and the high-energy traumas that this can entail, we sought to assess prognosis for radial neck fracture sustained in horse riding. HYPOTHESIS: Radial neck fracture sustained in horse riding is more severe and more frequently associated with other ipsilateral osteoarticular lesions which worsen prognosis. MATERIAL AND METHOD: We performed a multicenter retrospective comparative study in a continuous series of 39 patients. The inclusion criteria consisted of radius neck fracture in children under the age of 15 years. Endpoints comprised associated lesions at time of trauma, and ranges of elbow motion in pronation/supination and flexion/extension at last follow-up. RESULTS: Compared to other etiologies, radial neck fractures following horse-riding accidents were more frequently associated with other ipsilateral osteoarticular lesions (p=0.0002), and more often required open reduction (p=0.0409) and postoperative rehabilitation (p=0.041). However, there were no significant differences in any ranges of motion at last follow-up (p>0.05). CONCLUSION: Radial neck fractures following horse-riding accidents in children were more severe than those caused by other mechanisms. Awareness campaigns in riding clubs and development of specific protective equipment should be considered to reduce occurrence. LEVEL OF EVIDENCE: Therapeutic III - Retrospective comparative study.

C5/C6 brachial plexus palsy reconstruction using nerve surgery: long-term functional outcomes.

INTRODUCTION: In traumatic proximal brachial plexus lesions (i.e., C5/C6), reconstruction of the musculocutaneous, axillary and suprascapular nerves yields satisfactory short- and medium-term functional outcomes. HYPOTHESIS: Early functional outcomes after nerve surgery will be maintained in the long-term. METHODS: A retrospective analysis was done using the medical records of 29 patients with C5/C6 palsy treated by nerve surgery. Active range of motion and strength at the elbow (i.e., flexion) and shoulder (i.e., flexion, abduction, external rotation with the elbow at the side of the body and with the arm 90° abducted ) were evaluated clinically using a goniometre and the British Medical Research Council grading scale, respectively. RESULTS: At a mean follow-up of 46±15 months (25;76), the mean active elbow flexion was 126°±18° (90;150) and the mean strength was 3.8±0.5 (2;4). At the shoulder, mean active flexion, abduction, external rotation with the elbow at the side of the body and with the arm 90° abducted were 109°±39° (0;180), 99°±38° (0;180°), 12°±34° (-80;70) and 3°±21° (-40;50), while mean strength was 3.6±0.8 (0;4), 3.6±0.8 (0;4), 3.4±0.9 (0;4) and 2.5±1.2 (0;4), respectively. DISCUSSION: In cases of C5/C6 palsy, early nerve surgery yields satisfactory functional outcomes that are maintained over time for elbow flexion and shoulder elevation. However, when the teres minor is not reinnervated, it is difficult to restore satisfactory shoulder external rotation. LEVEL OF EVIDENCE: IV, Retrospective case study.

Endoscopic brachial plexus neurolysis in the management of infraclavicular nerve injuries due to glenohumeral dislocation.

INTRODUCTION: Infraclavicular brachial plexus (BP) injury secondary to glenohumeral joint (GHJ) dislocation is a rather common complication, which may be accountable for long-lasting deficits. The purpose of this study was to assess the potential benefits of BP neurolysis in such presentation, using an endoscopic approach. MATERIALS AND METHODS: All patients who underwent endoscopic BP neurolysis in the setting of infraclavicular BP palsy due to GHJ dislocation were included. Preoperative physical examination was conducted to classify the observed motor and sensitive deficits into nerves and/or cord lesions. Six weeks after the trauma, examination was repeated and endoscopic BP neurolysis was elected if no significant improvements were observed. If nerve ruptures and/or severe damages were identified during surgery, nerve reconstructions were conducted within a month; in other cases, follow-up examinations were conducted at 6 weeks, 3 and 6 months to assess the course of postoperative recovery. RESULTS: Eleven patients were included, including 6 men and 5 women, with a mean age of 43 ± 23 years (16;73). Six patients had at least one cord involved, four patients had isolated axillary nerve palsy, and one patient had a complete BP palsy. In 7 patients with cord lesions and/or isolated axillary nerve palsy, at least grade-3 strength, according to the British Medical Research Council grading system, was noted in all affected muscles within 6 weeks following the neurolysis; after 3 months of follow-up, grade-4 strength was observed in all muscles, and all but patients but one had fully recovered within 6 months. In 3 patients with isolated axillary nerve palsy, complete nerve ruptures (n=2) and severe damages (n=1) were identified under scopic magnification; secondary nerve transfers were conducted to reanimate the axillary nerve, and all patients fully recovered within a year. In one patient with complete BP palsy, improvements started after 6 months of follow-up, and full recovery was yielded after 2 years. No intra- and/or postoperative complications were noted. CONCLUSIONS: At the cost of minimal additional morbidity, endoscopic BP neurolysis appears to be a safe and reliable procedure to shorten recovery delays in most patients presenting with BP palsy due to GHJ dislocation.

Radial club hand treated with soft-tissue distraction and subsequent pin stabilization: mid- to long-term results.

Radial club hand deformities are commonly treated with arthrolysis to allow centralization of the ulna. In this retrospective cohort study of 31 hands in 28 patients, we aimed to assess the outcomes of correction using progressive distraction and subsequent percutaneous pinning of the wrist with a corrective ulnar osteotomy. Mean follow-up time was 7 years (range 2 to 20). The angulation of the hand-forearm complex was decreased after each step of the procedure. Mean correction of the angulation was 64°, and the residual total forearm-hand angulation was 12° after completion of the surgery. At the time of bony maturity (four patients), all wrists had fused. Fifty-eight reoperations were required in 31 wrists because of pin migration or breakage, and in addition 18 secondary osteotomies of the ulna were performed. From this study we conclude that distraction and pinning provide satisfactory and stable realignment of the wrist to correct the deformity, but this treatment has drawbacks regarding the high number of reoperations and the loss of wrist mobility.Level of evidence: IV.

Analysis of #PlasticSurgery in Europe: An Opportunity for Education and Leadership.

BACKGROUND: Prior studies demonstrate that social media are used by plastic surgeons to educate and engage. The hashtag #PlasticSurgery has been studied previously and is embraced by American plastic surgeons and journals; however, no studies have examined its use or adoption across Europe. METHODS: A retrospective analysis of 800 tweets containing the words "plastic surgery" or the hashtag #PlasticSurgery in four of the most spoken European languages worldwide excluding English (Spanish, #CirugiaPlastica; French, #ChirurgiePlastique; Portuguese, #CirurgiaPlastica; and German, #PlastischeChirurgie) was performed. The following were assessed: identity of author, subject matter, use of the hashtag #PlasticSurgery in each language, whether posts by surgeons and academic institutions were self-promotional or educational, and whether a link to a journal article or a reference in PubMed was provided. RESULTS: Seventeen percent and 3 percent of analyzed tweets came from plastic surgeons or academic institutions, respectively; only 17.5 percent of them were for educational purpose. None of them had any digital link to a peer-reviewed article or a scientific journal. CONCLUSIONS: This study demonstrates the low participation of plastic surgeons and academic institutions in social media (especially for education) in four of the major world languages. Social media should be considered in Europe as an opportunity to increase leadership, improve education, and spread knowledge of plastic surgery by board-certified plastic surgeons.

Double-Nerve Transfer to the Axillary Nerve in Traumatic Upper Trunk Brachial Plexus Injuries Using an Axillary Approach: Anatomical Description and Preliminary Case Series.

BACKGROUND: Restoration of shoulder external rotation remains challenging in patients with C5/C6 brachial plexus injuries (BPI). OBJECTIVE: To describe a double-nerve transfer to the axillary nerve (AN), targeting both its anterior and posterior motor branches, through an axillary route. METHODS: A total of 10 fresh-frozen cadaveric brachial plexuses were dissected. Using an axillary approach, the infraclavicular brachial plexus terminal branches were exposed, including the axillary, ulnar, and radial nerves. Under microscopic magnification, the triceps long head motor branch (TLHMB), anteromedial fascicles of the ulnar nerve (UF), the anterior motor branch of the axillary nerve (AAMB), and the teres minor motor branch (TMMB) were dissected and transected to simulate 2 nerve transfers, THLMB-AAMB and UF-TMMB. Several anatomical criteria were assessed, including the overlaps between fascicles when placed side-by-side. Six patients with C5/C6 BPI were then operated on using this technique. RESULTS: TLHMB-AAMB and UF-TMMB transfers could be simulated in all specimens, with mean overlaps of 37.1 mm and 6.5 mm, respectively. After a mean follow-up of 23 mo, all patients had recovered grade-3 strength or more in the deltoid and teres minor muscles. Mean active shoulder flexion, abduction, and external rotation with the arm 90° abducted were of 128°, 117°, and 51°, respectively. No postoperative motor deficit was found in the UF territory. CONCLUSION: A double-nerve transfer, based on radial and ulnar fascicles, appears to be an adequate option to reanimate both motor branches of the AN, providing satisfactory shoulder active elevations and external rotation in C5/C6 BPI patients.
