RESUMO
BACKGROUND: Displaced humeral shaft fractures are frequently treated by osteosynthesis in the active patient. We aimed to evaluate the results of intramedullary nailing (IMN) in the lateral position with the Neviaser approach and to compare them with those from IMN nailing in the standard position and conventional approach. METHODS: In the retrospectively evaluated, single-center study, we compared 20 cases of long IMN for fractures of the proximal or middle third of the humerus shaft (Multilock; Synthes Laboratory) in the lateral position with the percutaneous Neviaser approach with 52 cases of IMN in the standard position. The mean age of patients was 62 ± 21 years. Clinical outcomes were analyzed: Constant score, subjective shoulder evaluation score and range of motion. Radiographically, entry point at the proximal part of the humerus, the healing rate and the possible association between the critical shoulder angle (CSA) and the correct positioning of the nail were assessed. RESULTS: With a mean follow-up of 26 ± 2 months, the healing rate was 89% (64/72) in the overall series, (eight patients in non-union), with no difference between the two groups. The overall mean active anterior elevation (AAE) was 125 ± 22°, mean external rotation (ER1) was 35 ± 17°, and mean internal rotation (IR) was at L3. The mean Constant score was 58 ± 23 and subjective shoulder evaluation score 73 ± 12%. ranges of motion were better in the lateral than standard position group (AAE 133 ± 17 vs. 122 ± 23, P = .03; ER1 47 ± 13 vs. 30 ± 16, P < .001; IR T12 vs. L5, P = .02). The nail was less often protruding in the lateral than standard position group (1/20 [5%] vs. 20/52 [38.5%], P = .002). The nail was better positioned from the anteroposterior view (nail centered: 16/20 [75%] vs. 26/52 [50%], P = .047) and lateral view (nail centered: 18/20 [90%] vs. 34/52 [65.4%], P = .02) in the lateral than standard position group. We found no association between nail position, type of approach and CSA. CONCLUSIONS: In the short-term follow-up, osteosynthesis of humeral shaft fractures by using long IMN in the lateral position with the Neviaser approach is a reliable technique. The positioning of the nail, in particular its entry point, and the clinical results were better with the lateral position and Neviaser approach than with the standard position and conventional approach. Further studies with a larger number of patients, assessment of the learning curve, and analysis of the impact of this technique on comorbidities (unchanged cerebral perfusion) are needed to fully validate this technique.
RESUMO
PURPOSE: The relationship between functional shoulder deficits in children with neonatal brachial plexus palsy (NBPP) and magnetic resonance imaging (MRI) shoulder abnormalities was evaluated. METHODS: Shoulder function was assessed in 16 children (mean age: 5.8 years; range: 3-12 years) with NBPP based on shoulder rotator muscle strength, as measured using an isokinetic dynamometer and the modified Mallet score. The thickness and fatty infiltration of the subscapularis and infraspinatus muscles, and the morphology of the glenoid on MRI, were also determined. RESULTS: The highest subscapularis fatty infiltration subgroup of NBPP patients promoted the highest alteration muscle thickness and modified Mallet score. CONCLUSIONS: In NBPP children, subscapularis impairments play a major role in the functional limitations. This study of pediatric NBPP patients highlighted the value of adding an examination of the muscles to routine MRI assessment of bone parameters in the shoulders of NBPP children. TRIAL REGISTRATION: NCT03440658.

OBJECTIVE: To establish international recommendations for the management of spastic equinovarus foot deformity. DESIGN: Delphi method. SETTING: International study. PARTICIPANTS: A total of 24 international experts (N=24) in neuro-orthopedic deformities, from different specialties (Physical and Rehabilitation Medicine physicians, neurologists, geriatricians, orthopedic surgeons, neurosurgeons, plastic surgeons). INTERVENTIONS: Experts answered 3 rounds of questions related to important aspects of diagnosis, assessment, and treatment of spastic equinovarus foot deformity. MAIN OUTCOME MEASURES: A consensus was established when at least 80% of experts agreed on a statement RESULTS: A total of 52 items reached consensus. Experts recommend assessing effect of the deformity on functional activities before treatment. Before treatment, it is crucial to differentiate spastic muscle overactivity from soft tissue contractures, identify which muscles are involved in the deformity, and evaluate the activity of antagonist muscles. Motor nerve blocks, 2-dimensional video analysis, and radiologic examinations are often required to complement a clinical examination. The treatment of equinovarus foot depends on the correctability of the deformity and the patient's ability to stand or walk. The preoperative assessment should include an interdisciplinary consultation that must finalize a formal agreement between physicians and the patient, which will define personalized attainable goals before surgery. CONCLUSION: The establishment of guidelines on managing equinovarus foot will help physicians and surgeons, specialists, and nonspecialists to diagnoses and assess the deformity and direct patients to a network of experts to optimize patient functional recovery and improve their autonomy.

BACKGROUND: In symptomatic glenohumeral osteoarthritis, arthroplasty is the gold standard to restore a mobile and painless shoulder. The kind of arthroplasty chosen is mainly based on the evaluation of the rotator cuff and the type of glenoid. The aim of this study was to analyze the scapulohumeral arch in primary glenohumeral osteoarthritis (PGHOA) with an uninjured cuff and to determine whether posterior humeral subluxation influences the Moloney line, which corresponds to an intact scapulohumeral arch. MATERIALS AND METHODS: Between 2017 and 2020, 58 anatomic total shoulder arthroplasties were implanted in the same center. We included all patients with complete preoperative imaging (radiographs and magnetic resonance imaging or arthro-computed tomography scans) assessing an intact rotator cuff. A total of 55 shoulders that had undergone surgery with a total anatomic shoulder prosthesis were analyzed after determination of the type of glenoid in the frontal plane according to the Favard classification on an anteroposterior radiograph and in the axial plane according to the Walch classification on computed tomography scans. The grade of osteoarthritis was evaluated according to the Samilson classification. We analyzed whether there was a rupture of the Moloney line on the frontal radiograph and assessed the acromiohumeral distance. RESULTS: After preoperative analysis of 55 shoulders, 24 shoulders had type A glenoids and 31 had type B glenoids. Scapulohumeral arch rupture was observed in 22 shoulders, and posterior subluxation of the humeral head was found in 31 shoulders, of which 25 had type B1 glenoids and 6 had type B2 glenoids according to the Walch classification. Most glenoids were type E0 (n = 47.85%). Incongruity of the Moloney line was more frequent in shoulders with type B glenoids (20 of 31 [65%]) than those with type A glenoids (2 of 24 [8%], P < .001). No patient with a type A1 glenoid (0 of 15) had a rupture of the Moloney line, and only 2 patients with a type A2 glenoid (2 of 9) had incongruity of the scapulohumeral arch. CONCLUSION: In PGHOA, rupture of the scapulohumeral arch seen on anteroposterior radiographs, also known as the Moloney line, may be an indirect sign of posterior humeral subluxation, corresponding to a type B glenoid per the Walch classification. Incongruity of the Moloney line may indicate a rotator cuff injury or posterior glenohumeral subluxation with an intact cuff in PGHOA.

AIMS: The aim was to evaluate the results of radial head prostheses (RHP) in Essex-Lopresti injury (ELI) and to compare results after RHP between acute and chronic ELI. PATIENTS AND METHODS: Thirty-one patients treated with RHP for ELI were selected from a multicenter retrospective series of 310 RHP, with follow-up greater than two years. Two groups were acute ELI group (n=19, average diagnosis = 5+/-9 days) and chronic ELI group (n=12, average diagnosis 8.4+/-7.1 months). RHP was associated in some cases with K-wires: during acute ELI to stabilize the distal radio-ulnar joint (n=4) or during chronic ELI with ulnar osteotomy or palliative surgery (n=4). Clinical and radiologic evaluation was performed including analysis of the complications and revisions rates, pain level, range of motion, and MEPS (Mayo Elbow Performance Score) and DASH score (Disabilities of the Arm, Shoulder and Hand). RESULTS: At last follow-up (71+/-38 months), survival of RHP in the acute ELI group was 84% (16/19) and 92% (11/12) in the chronic ELI group without statistically significant difference. Flexion (acute=131degrees+/-13.4 vs chronic=22+/-12.8, p=0.041) and supination (ELI=71+/-16.8 vs chronic=58+/-17.4; p=0.045) were better in acute ELI group. The DASH score was also better in the acute group (15+/-9.1 versus 24+/-15.2, p=0.048). There was more advanced stage of humero-radial osteoarthritis in the chronic ELI group (0.7+/-0.5 versus 1.4+/-0.6, p=0.041). CONCLUSION: RHP in acute ELIs provide better clinical results, although RHPs are part of the therapeutic arsenal to treat chronic ELI.

PURPOSE: Quantifying changes in shoulder external rotation range of motion and strength after lower trapezius transfer in children with obstetric brachial plexus palsy (OBPP). METHODS: This prospective study included five children with sequelae of OBPP, with a mean age of 6.4 years (range: 4-12 years) who underwent lower trapezius tendon transfer to restore active external rotation (ER) of the shoulder. Pre-operatively and at a 12-month follow-up assessment, we analyzed the passive and active shoulder ER, the modified Mallet score, and the shoulder rotator muscles strength using an isokinetic device. RESULTS: Clinical parameters improved significantly after trapezius transfer pre-operative passive ER from -8° (range: -20-0°) to 37° (range: 15-50°) (p = 0.035), the modified Mallet score from 13 (range: 10-15) to 18 (range: 17-19) (p = 0.035). Strength testing revealed improved ER muscle strength in all five cases; the mean Peak Torque increased from 1.95 to 4.46 N·m, albeit non-significantly (p = 0.062). Two patients exhibited a winged scapula post-operatively. CONCLUSION: Lower trapezius transfer seems encouraging to restore shoulder external rotation in OBPP children but with non-significant strength improvement.

STUDY DESIGN: Psychometric Study. OBJECTIVES: To assess responsiveness of the Motor Capacities Scale (MCS) in people with tetraplegia who have undergone upper limb reconstructive surgery. SETTINGS: Rehabilitation clinics in France. METHODS: The MCS is an arm/hand function test with 31 basic tasks, subdivided into four sub-categories (MCS A, MCS B, MCS C, and MCS D). Data were recorded preoperatively and following full completion of the surgical program. The Functional Independence Measure (FIM) and a ten-point numeric scale related to patients' satisfaction with the overall surgical result were included. Data were analyzed using responsiveness measures-the effect size (ES), the standardized response mean (SRM), and the minimal clinically important difference (MCID). RESULTS: Twenty-seven participants were included. Fourteen patients underwent unilateral surgery and 13 bilateral surgery. ES and SRM were moderate or good (ES/SRM of MCS B = 0.76/0.81, ES/SRM MCS C = 0.68/0.77, and ES/SRM MCS D = 0.77/0.88). For MCS A and FIM, both SRM and ES showed a small degree of responsiveness. For the MCS total score, the ES value indicated a moderate degree of responsiveness while SRM was excellent. Total MCS score, MCS C subscore and MCS D subscore showed significantly higher ES values in the "bilateral surgery" group than in the "unilateral group". The estimation of MCIDs showed low threshold values of MCS scores changes (total score and subscores) beyond which the satisfaction rate is >6. CONCLUSIONS: This study provides evidence of acceptable responsiveness of the MCS to changes using the SRM following upper limb reconstruction in patients with tetraplegia.

BACKGROUND: We hypothesized that a selective neural electrical stimulation of radial and median nerves enables the activation of functional movements in the paralyzed hand of individuals with tetraplegia. Compared to previous approaches for which up to 12 muscles were targeted through individual muscular stimulations, we focused on minimizing the number of implanted electrodes however providing almost all the needed and useful hand movements for subjects with complete tetraplegia. METHODS: We performed acute experiments during scheduled surgeries of the upper limb with eligible subjects. We scanned a set of multicontact neural stimulation cuff electrode configurations, pre-computed through modeling simulations. We reported the obtained isolated and functional movements that were considered useful for the subject (different grasping movements). RESULTS: In eight subjects, we demonstrated that selective stimulation based on multicontact cuff electrodes and optimized current spreading over the active contacts provided isolated, compound, functional and strong movements; most importantly 3 out of 4 had isolated fingers or thumb flexion, one patient performed a Key Grip, another one the Power and Hook Grips, and the 2 last all the 3 Grips. Several configurations were needed to target different areas within the nerve to obtain all the envisioned movements. We further confirmed that the upper limb nerves have muscle specific fascicles, which makes it possible to activate isolated movements. CONCLUSIONS: The future goal is to provide patients with functional restoration of object grasping and releasing with a minimally invasive solution: only two cuff electrodes above the elbow.

PURPOSE: Constructing a lateral key pinch (KP) is a universal aim of any functional upper limb surgery program for tetraplegia. Three stages are required: (1) activating the pinch mechanism by flexor pollicis longus tenodesis to the radius or by tendon transfer to the flexor pollicis longus, (2) simplifying the polyarticular chain, and (3) positioning the thumb column. We compared 2 techniques for accomplishing the latter stage, 1 utilizing arthrodesis of the carpometacarpal joint (CMC) and 1 that did not require arthrodesis of the CMC. MATERIALS AND METHODS: We reviewed 40 cases of KP reconstruction at a mean follow-up of 7.4 years: 17 who had undergone CMC arthrodesis and 23 without CMC arthrodesis. In this group, an abductor pollicis longus tenodesis was necessary to properly position the thumb column in 17 patients. RESULTS: Active KP cases with CMC arthrodesis were significantly stronger than those without an arthrodesis. For passive KP cases, the difference between those cases with CMC arthrodesis and those without was not significant. Regarding opening, for active KP cases with CMC preservation alone, the mean distance between the thumb pulp and the index finger was 4.0 cm at rest and 5.8 cm when passively grasping large objects; for active KP cases without arthrodesis, these values were 3.4 and 6.8 cm, respectively, with the wrist in flexion. For passive KP cases, these values were 2.2 and 3.5 cm with CMC arthrodesis compared with 2.4 and 6.9 cm without arthrodesis. Overall, 23.5% of patients with CMC arthrodesis could not maintain contact between the thumb and the index finger compared with 30.4% without arthrodesis. CONCLUSIONS: Active KP is stronger with than without CMC arthrodesis; however, the KP reconstruction does not open as far when grasping large objects. For passive KP, CMC arthrodesis significantly limits passive opening, with no gain in strength. Neither technique is superior in terms of KP stability. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: Shoulder arthroscopic arthrodesis is an uncommon and non-standardized procedure. Results are poorly evaluated. We describe the findings in 8 patients who underwent shoulder arthroscopic arthrodesis for brachial plexus injury. METHODS: The humeral head and glenoid were excised through standard arthroscopic portals. A Hoffmann external fixator and cannulated screws were used to stabilize the shoulder. Standard clinical assessment and radiographic evaluation were performed each month until bony fusion occurred. With a mean follow-up of 28 months, functional evaluation included pain level (on a 0- to 10-mm visual analog scale); American Shoulder and Elbow Surgeons index; Disabilities of the Arm, Shoulder and Hand score; and Simple Shoulder Test score. Mobility was systematically investigated. Blood loss was assessed by measuring hematocrit proportion. RESULTS: Glenohumeral fusion was achieved in all 8 patients. The mean time to arthrodesis was 3 months (range, 2-8 months). At last follow-up, the mean pain level was 1 (range, 0-4); the mean American Shoulder and Elbow Surgeons score was 69; the mean Disabilities of the Arm, Shoulder and Hand score was 36; and the mean Simple Shoulder Test score was 4. Mean active flexion and abduction were 80° (range, 60°-90°) and 59° (range, 40°-80°), respectively. Mean blood loss during the perioperative period was 432 mL (range, 246-792 mL). We observed one superficial wound infection and one migration of an acromiohumeral screw. These complications did not compromise the final results. CONCLUSIONS: Arthroscopic arthrodesis of the shoulder can be a reliable procedure and associated with a low rate of complications.

BACKGROUND: Posterior humeral subluxation is the main cause of failure of total shoulder arthroplasty. We aimed to compare humeral head subluxation in various reference planes and to search for a correlation with retroversion, inclination, and glenoid wear. MATERIALS AND METHODS: We included 109 computed tomography scans of primary glenohumeral osteoarthritis and 97 of shoulder problems unrelated to shoulder osteoarthritis (controls); all computed tomography scans were reconstructed in the anatomic scapular plane and the glenoid hull plane that we defined. In both planes, we measured retroversion, inclination, glenohumeral offset (Walch index), and scapulohumeral offset. RESULTS: Retroversion in the scapular plane (Friedman method) was lower than that in the glenoid hull plane for controls and for arthritic shoulders. The threshold of scapulohumeral subluxation was 60% and 65% in the scapular plane and glenoid hull plane, respectively. The mean upward inclination was lower in the scapular plane (Churchill method) than in the glenoid hull plane (Maurer method). In the glenoid hull plane, 35% of type A2 glenoids showed glenohumeral offset greater than 75%, with mean retroversion of 25.6° ± 6° as compared with 7.5° ± 7.2° for the "centered" type A2 glenoids (P < .0001) and an upward inclination of -1.4° ± 8° and 6.3° ± 7° (P = .03), respectively. The correlation between retroversion and scapulohumeral offset was r = 0.64 in the glenoid hull plane and r = 0.59 in the scapular plane (P < .05). CONCLUSION: Measurement in the glenoid hull plane may be more accurate than in the scapular plane. Thus, the glenoid hull method allows for better understanding type B3 of the modified Walch classification.

PURPOSE: Management of proximal humeral tumours remains a surgical challenge. No study to date has assessed the quality of life scores following the composite reverse shoulder arthroplasty for this indication. We, therefore, evaluated function and quality of life following reconstruction with allograft for malignant tumour of the humerus. METHODS: A series of six cases of humeral tumour treated by a single surgeon in a single centre was reviewed after a mean follow-up of 5.9 years. The tumours included two chondrosarcomas, one plasmocytoma and three metastases. Resection involved bone epiphysis, metaphysis and diaphysis in five cases (S3S4S5A) and epiphysis and metaphysis in one case (S3S4A). For reconstruction, an allograft composite reverse shoulder arthroplasty was used in all the cases. Outcomes were assessed with range of motion, the QuickDash score and the Short Form 12 (SF-12) Health Survey. Radiographs assessed osseointegration and complications. RESULTS: At the final follow-up, the mean shoulder range of motion were respectively 95°, 57° and 11° for forward flexion, abduction and external rotation. Mean QuickDASH score improved from 28 to 41 and VAS-pain scores improved from 5.1 to 2.3. The post-operative MSTS score was 73% and the Constant score was 46.1/100. The SF-12 PCS and MCS scores were also improved, respectively from 44.4 and 39.7 to 45.5 and 56.1. The mean satisfaction score was 8.1/10. CONCLUSIONS: Composite reverse shoulder arthroplasty is a viable alternative for reconstruction after resection of malignant humeral tumour. Although total tumour resection was the most important objective, the functional and quality of life scores were satisfactory.

PURPOSE: To evaluate whether the congruency between the joint surfaces of the lunate fossa of the distal radius and the proximal capitate might be a prognostic factor for functional, clinical, or radiographic results after proximal row carpectomy (PRC). METHODS: After reconstructing the computed tomographic arthrogram of patients with PRC, we evaluated the shape of the proximal capitate by measuring the radius of curvature of the tip of the capitate. The congruency of the future radiocapitate joint was then evaluated by the radiocapitate index in the frontal and sagittal planes. This was calculated by dividing the radius of curvature of the tip of the capitate by the mean radius of curvature of the lunate fossa. We determined the relationship between these morphological results and the functional (Disabilities of the Arm, Shoulder, and Hand [DASH] score, Mayo Wrist score, and pain relief), clinical (mobility and strength) and x-ray results (radiocapitate arthrosis). RESULTS: A total of 27 patients were reviewed at a mean follow-up of 59 months. The shape of the proximal capitate did not affect outcomes. In the frontal plane, a better radiocapitate congruency was significantly associated with an increase in wrist flexion and better functional results for the DASH. There was a non-significant relationship between congruency and improvement of Mayo Wrist score and pain relief. In the sagittal plane, the DASH score tended to improve when congruency was better. CONCLUSIONS: The shape of the capitate was not a prognostic factor for functional outcome after PRC. The radiocapitate index seems more relevant in predicting results at last follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Radial head prostheses are indicated for treatment of complex radial head fractures not amenable for fixation. After the initial experience with silastic implants, metallic or pyrocarbon arthroplasty have been used for 20 years. Little is known about complications related to these implants. Main complications are related to loosening whether they are cemented or not cemented. Hypotheses have been proposed like inadequate stem design, insufficient cement technique, stress shielding, and foreign body reactions secondary to polyethylene wear. Pain and stiffness are other common complications often related to oversized radial head component or overstuffing of the joint with excessive lengthening of the radius. Instability can be another complication in the context of more complex trauma with lateral collateral ligament complex lesion and coronoid fracture. Fixation of the coronoid fracture, reinsertion of the lateral collateral ligament complex, and the use of monobloc radial head prosthesis are recommended to stabilize the joint. Finally, osteoarthritis is common with follow-up.

BACKGROUND: This article is a prospective review of patients with spinal cord injury who underwent multidisciplinary consultation from January 2005 to September 2013 for pain in one or both shoulders. METHODS: We performed clinical, functional, and lesion evaluations of 38 patients with paraplegia and quadriplegia presenting with rotator cuff pathologies. RESULTS: Surgery was indicated and performed on 38 shoulders in 28 patients. The lesion assessment during surgery showed injuries that were more severe than one would have thought based on imaging data. The mean pain intensity rating in the operative and nonoperative groups was 0 and 1.6, respectively, at rest and 2 and 4.9, respectively, during paroxysmal peaks. On average, for patients who had surgery, the Functional Independence Measure score decreased by 2.3. The mean satisfaction index in operated patients was 8.5 of 10. CONCLUSIONS: When the surgical indication was based on a multidisciplinary decision, no negative results were reported that could have challenged the validity of this decision. Pain relief was the primary benefit reported after surgery. The functional status was modified because of the technical aids needed to prevent shoulder overuse. There are several arguments in favor of rotator cuff surgery for wheelchair-bound patients with spinal cord injury. Because of their functional impairments, wheelchair-bound patients will continue to overburden their shoulders after rotator cuff surgery. A multidisciplinary approach emerges as the solution to inform and educate patients to limit the risk of recurrence.

Background: Inferior glenohumeral subluxation (GHS) can cause disabling pain in hemiplegics. Conservative treatments have not been proven to be effective or maintained over time. A few studies have shown the benefits of surgical treatment. The objective of our study was to evaluate the medium-term clinical and radiological results of arthroscopic glenohumeral suspensioplasty surgery by biceps tenodesis in the setting of painful GHS in hemiplegics. Methods: We conducted a retrospective study of patients who underwent arthroscopic glenohumeral suspensioplasty. The assessment, at a minimum of 1 year, included a clinical evaluation (pectoralis major spasticity, pain, range of motion, satisfaction) and a radiographic evaluation (Dursun classification, height of subacromial space). Results: Five patients with a mean age of 51 years (36-72 years) were included at a mean follow-up of 40 months (12-70). Satisfaction was good in 80% of patients. Pain decreased in all patients, but not significantly. Four patients (80%) would repeat the procedure if it were necessary. In all patients, a reduction in GHS over time was observed, with a reduction in subacromial height, except in 1 patient who suffered a tenodesis rupture during a fall. Conclusion: Our results suggest that arthroscopic glenohumeral suspensioplasty by biceps tenodesis may be a therapeutic option in hemiplegic patients with painful GHS.
RESUMO
INTRODUCTION: The widespread pre-hospital use of tourniquets, particularly in the upper limb, raises questions about associated morbidity, which has been little studied and may have serious consequences for functional prognosis. METHODS: A review of 9 patients was carried out, analyzing pre-hospital tourniquet use in terms of complications affecting recovery. RESULTS: There were serious complications: musculocutaneous nerve palsy in 1 patient, and compartment syndrome, rhabdomyolysis and ischemia-reperfusion syndrome in another. A role of prolonged pre-hospital tourniquet application in postoperative infection was also suspected in 2 patients. DISCUSSION: The risk-benefit ratio and indications for using a tourniquet on the upper limb in the pre-hospital setting need to be reconsidered.
RESUMO
Inferior glenohumeral subluxation represents one of the causes of disabling pain in patients with hemiplegia after a stroke. In the case of failure of medical treatment by orthosis or electrical stimulation, surgical treatment of suspensionplasty has been described with good results. We describe here an arthroscopic technique of glenohumeral suspensionplasty by tenodesis of the biceps, proposed in the context of a painful glenohumeral subluxation in patients with hemiplegia.
