Abstract Introduction Little information is available on the clinical and radiographic outcome of intraoperative, non- to minimally displaced humeral fractures that occur during implantation of a stemmed, reverse shoulder prosthesis but are only recognized on routine postoperative radiographs. The goal of this study is to report the clinical and radiographic outcome for this rarely reported fracture type. Materials and methods 39 conservatively treated non- to minimally displaced intraoperative periprosthetic humeral fractures after stemmed RTSA were detected from our radiographic database between 1.1.2006 and 31.1.2018. Exclusion criteria were lack of patient consent, preoperative humeral fracture, and revision arthroplasties. Clinical (absolute and relative Constant score, the Subjective Shoulder Value) and radiographic (conventional radiographs) assessment was performed preoperatively, at 6 weeks (only radiographically) and at latest follow-up with a minimum follow-up of 2 years. Results 35 patient’s with a mean age of 72 years (range 32–88, SD ± 11 years) and a mean follow-up of 53 months (range 24–124, SD ± 31) were included in the study. At latest follow-up, all clinical outcome parameters except external rotation improved significantly. A complication rate of 17% (n:6) was recorded. At 6 weeks after the index surgery, none of the radiographs showed a fracture displacement or a sintering of the stem. At latest follow-up, all fractures were healed and no stem loosening was observed in any of the shoulders. Conclusions Non- to minimally displaced intraoperative periprosthetic humeral fractures in RTSA have an incidence of about 5% in this series of mainly uncemented press-fit stems. They generally heal without any further treatment and are not associated with stem loosening or compromise the clinical outcome after primary RTSA. Except slight restriction in the postoperative rehabilitation protocol, no further attention or action is needed.

Abstract Background The Eclipse® (Eclipse® is a trademark of Arthrex, Naples, Florida) stemless shoulder prosthesis offers the surgeon the advantage of bone stock preservation and at the same time avoids the drawbacks of a resurfacing arthroplasty. Previous studies have shown radiographic changes on serial follow up of the Eclipse prosthesis. This study attempts to assess the significance of these radiographic changes and effect of cuff related pathology on the mid-term outcome of the Eclipse prosthesis. Methods Between July 2005 and October 2008, 29 shoulders underwent shoulder arthroplasty with the Eclipse prosthesis; 23 shoulders, (seven women and 16 men) were available for the final follow up. The range of motion, Constant Score; age adjusted Constant Score, Subjective Shoulder Value and radiographs were assessed at serial follow-ups. Results Significant improvements were seen in the Constant Score (78.9 ±20.1) compared to pre-operative score (32.9 ±5.2); also forward elevation, abduction and external rotation improved to 142.9 ± 36.6 °, 135.2 ± 40.5 ° and 49.8 ± 21.9 ° at 72 months (p < 0.001). Radiolucent lines and localised osteopenia, did not statistically impact on the clinical outcome. Partial tears of the supraspinatus and subscapularis had a negative impact on the Subjective Shoulder Value (p < 0.05) Partial or complete tears of the subscapularis led to worse Constant Score on follow up (p < 0.05). Conclusions The presence of radiolucent lines or localised osteopenia does not influence the mid term clinical outcome. Pre -operative partial supraspinatus tears or tears of the subscapularis lead to an inferior outcome.

Complex proximal third diaphyseal humeral fractures are uncommon patterns of injury mainly caused by high energy trauma. The anatomical shape of the humerus, the presence of the deltoid tuberosity and the close proximity of the radial nerve into the radial groove represent challenge elements to deal with. Historically, straight plates were manually twisted; subsequently, helical plates created for other anatomical sites (as distal tibia) were used in humeral fractures. In both these experiences surgeons observed several disadvantages. More recently, dedicated helical plates have been created. In this study, we expose our surgical technique for using helical humeral plates (A.L.P.S.® Proximal Humeral Plating System, Zimmer Biomet), with its advantages and operative recommendation. From 2019 to 2021, nine patients who were admitted to our institution for humeral fractures involving the proximal third diaphysis have been treated with humeral helical plates. At one and six months after surgery, standard antero-posterior and lateral radiographs were obtained, and at last follow-up (fourteen months on average) clinical evaluation was performed through range of motion assessment, Constant score and DASH score questionnaires. At six months, all fractures have healed. At last follow-up (fourteen months on average, 6-22) the average range of motion were flexion 135° (90°-180°); abduction 124° (85°-180°); external rotation 52° (20°-80°), internal rotation at L3 (between scapulae-trochanter). Average Constant Shoulder Score was 70 (33-96), average Dash score was 21 (range 1,7-63). Three patients experienced temporary radial nerve palsy from injury, with subsequently improvement at EMG analysis within eight months from surgery. In our opinion this strategy avoids the deltoid tuberosity and reduces the risk of radial nerve injury, increasing the possibility of a rapid functional recovery after surgery.

Clinical studies on primary osteoarthritis have shown better results of total shoulder arthroplasty (TSA) compared to hemiarthroplasty (HA) regarding the function, revision rate and postoperative pain relief. However, a clear recommendation for implantation of TSA or HA, depending on the glenoid type of erosion, does not exist. The aim of the study was to compare the results of TSA and HA with respect to the preoperative glenoid type. In this study, 41 patients were examined retrospectively; among them, 25 patients were treated with stemmed anatomic TSA and 16 with stemmed anatomic HA. The degree of osteoarthritis was determined according to Samilson and the glenoid erosion was classified according to Walch. The clinical outcome of the patients was determined by using the Constant Score (CS) and the Simple Shoulder Test at final follow-up. Patients after TSA demonstrated a significantly improved internal rotation compared to HA patients. Patients with preoperative B1 glenoid showed better pain relief after TSA compared to HA. For patients with preoperative type A2 glenoid a significantly higher CS was found after TSA compared to HA. We were able to show good short-term results after TSA and HA. Our findings suggest a better internal rotation for TSA compared to HA, superior clinical outcome for patients with preoperative A2 glenoid and lower pain level for patients with a preoperative B1 glenoid. However, these results need to be confirmed by further studies.

Aims The aim of this study was to report the outcomes of different treatment options for glenoid loosening following reverse shoulder arthroplasty (RSA) at a minimum follow-up of two years. Patients and Methods We retrospectively studied the records of 79 patients (19 men, 60 women; 84 shoulders) aged 70.4 years (21 to 87) treated for aseptic loosening of the glenosphere following RSA. Clinical evaluation included pre- and post-treatment active anterior elevation (AAE), external rotation, and Constant score. Results From the original cohort, 29 shoulders (35%) were treated conservatively, 27 shoulders (32%) were revised by revision of the glenosphere, and 28 shoulders (33%) were converted to hemiarthroplasty. At last follow-up, conservative treatment and glenoid revision significantly improved AAE, total Constant score, and pain, while hemiarthroplasty did not improve range of movement or clinical scores. Multivariable analysis confirmed that conservative treatment and glenoid revision achieved similar improvements in pain (glenoid revision vs conservative, beta 0.44; p = 0.834) but that outcomes were significantly worse following hemiarthroplasty (beta -5.00; p = 0.029). Conclusion When possible, glenoid loosening after RSA should first be treated conservatively, then by glenosphere revision if necessary, and last by salvage hemiarthroplasty Cite this article: Bone Joint J 2019;101-B:461–469.

Retear Rate

Background: The retear rate after primary rotator cuff (RC) reconstruction is high and commonly leads to poorer clinical outcomes and shoulder function. In the case of primary failure, revision RC reconstruction (RCR) has become increasingly important to re-create RC integrity and improve outcomes. To date, clinical and structural outcomes after RCR have not been sufficiently investigated and described at midterm follow-up. Hypothesis/Purpose: The purpose was to evaluate the clinical and radiological outcomes after revision RCR. It was hypothesized that revision RCR significantly improves clinical outcomes and that the outcomes positively correlate with tendon integrity on magnetic resonance imaging (MRI). Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent revision RCR between 2008 and 2014 were retrospectively evaluated with a minimum follow-up of 2 years. Outcomes were assessed by a clinical examination, a visual analog scale for pain (VAS), the Constant Score (CS), the American Shoulder and Elbow Surgeons (ASES) score, and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Tendon integrity was determined using 3-T MRI and graded according to the Sugaya classification. Results: Thirty-one of 40 patients (77.5%) were available for the final assessment at a mean follow-up of 50.3 ± 20.4 months. Clinical outcome scores significantly improved from preoperatively to postoperatively for the CS (39.7 ± 16.7 to 65.1 ± 19.7; P < .001), ASES (44.2 ± 17.7 to 75.2 ± 24.8; P < .001), and DASH (68.6 ± 15.1 to 21.5 ± 19.1; P < .001). The VAS score decreased from 6.1 ± 1.8 preoperatively to 1.3 ± 1.8 at final follow-up ( P < .001). MRI demonstrated a retear rate of 55.5%. No differences in CS, ASES, and DASH scores were detected between patients with an intact repair and failure. Abduction strength was not significantly different in patients with an intact repair and retears (55.5 N vs 44.0 N, respectively, P = .52). Conclusion: Revision RCR improves clinical outcomes and shoulder function at midterm follow-up. The clinical outcome scores were comparable in patients with an intact repair and those with failed RC healing. Therefore, tendon integrity was not correlated with better clinical outcomes after revision RCR at final follow-up.

Radiographic Changes

Abstract Introduction Stemmed humeral implants have represented the gold standard in total shoulder arthroplasty (TSA) for decades. Like many other joints, the latest trends in TSA designs aim at bone preservation. Current studies have demonstrated that native proximal humeral bone stresses are most closely mimicked by stemless implants. Nevertheless, there are concerns about the long-term performance of stemless designs. The aim of the present study was to evaluate the long-term radiographic changes at the proximal humerus in anatomical stemless press-fit TSA. Materials and Methods Between 2008 and 2010, 48 shoulders in 43 patients were resurfaced using an anatomic stemless shoulder prosthesis (TESS, Biomet). Thirty shoulders in twenty-five patients who were aged 65.7 ± 9.9 (34 to 82) years were available for clinical and radiographic review at a mean follow-up of 94.0 ± 8.9 (78 to 110) months. Results Radiographic changes of the proximal humerus due to stress shielding were found in 38.4% of the stemless TESS implants. Mild stress shielding accounted for 80% of the observed radiographic changes. Radiographs exhibited stable fixation of the stemless humeral press-fit implant at early and late follow-up. In contrast, radiolucent lines at the glenoid implant were found in 96.1% of the cases. Irrespective of the degree of radiographic changes, clinical scores (VAS, Quick-DASH, Constant score) significantly improved at follow-up. Conclusions The anatomic stemless press-fit implant seems to be favorable in terms of implant-related stress shielding. Clinical outcome was not affected by radiographic changes, demonstrating an 8-year clinical performance that seems to be comparable to conventional stemmed TSA.

Abstract Introduction Reverse shoulder arthroplasty (RSA) has become a well-established treatment option for multiple disorders of the shoulder joint. In recent years, implant designs and configurations have been modified in order to improve function and avoid complications. Lateralization on the glenoid and the humeral side has been described to improve function and decrease radiographic scapular notching. Data on the clinical and radiographic results of bipolar lateralization in RSA are lacking. Methods In 38 cases, RSA was performed using an uncemented humeral short-stem component with a 145° neck–shaft angle in combination with bone lateralization on the glenoid side (Bony Increased-Offset Reversed Shoulder Arthroplasty, BIO-RSA; Wright Medical Inc., Memphis, TN, USA). Mean follow-up was 19 months (range 12–34 months). Patients were followed clinically using the Constant score as well as range of motion for shoulder flexion and external rotation. Radiographs in two different plains were analyzed for implant seating and the occurrence of scapular notching. Results There was a significant increase in all measured clinical parameters. Forward flexion increased from a mean of 75° preoperatively to 151° postoperatively, and mean Constant score increased from 21 to 71 points postoperatively (p < 0.001). Glenoid notching of grade 1 according to Sirveuax was observed in 3 out of 35 cases (9%); no grade 2, 3, or 4 notching was present. Revision surgery was necessary in one case (3%). Conclusion RSA with bipolar lateralization leads to excellent clinical outcomes, low complication rates, and low rates of radiographic scapular notching. Longer follow-up and prospective randomized trials are needed. Level of evidence Level IV.

Background: Trapeziometacarpal arthroplasties are designed to restore an adequate level of mobility, stability, and grip strength. In this article, pain and functional and radiographic outcome of Ivory arthroplasty in male patients are investigated. Methods: Between 2005 and 2012, the Ivory arthroplasty was inserted in 21 male patients with degenerative trapeziometacarpal osteoarthritis, of which 14 patients were found eligible for inclusion. Mobility, grip strength, patient self-assessment (pain; Quick Disabilities of the Arm, Shoulder, and Hand [QuickDASH]), and radiographic outcome were measured. Twenty-two female patients who received an Ivory arthroplasty between 2005 and 2007 were included and underwent the same evaluation. Age at primary surgery, survival rate of the implant, and clinical outcome were compared between the 2 groups. Results: In both groups, QuickDASH score and mean pain sensation improved significantly. The improvement in mobility obtained significance in the female group. In the male group, 7 arthroplasties failed (mean follow-up of 65 months). In the female group, 3 of the 24 arthroplasties failed (mean follow-up of 123 months). Kaplan-Meier survival analysis demonstrated a significant lower implant survival in the male group. Conclusions: Decrease in muscle mass and decline in grip strength that postmenopausal women tend to experience might explain the significant difference in implant survival between sexes. In 4 of the 7 failed arthroplasties in the male group, no surgical revision was required. Trapeziometacarpal arthroplasty, even after radiographic failure, still served as a spacer, avoiding collapse of the thumb base. Nevertheless, the failure rate of the Ivory arthroplasty in male patients is high, and an alternative treatment should be considered.

A szerzők 2000-ben új módszert vezettek be osztályukon a felkar proximalis végének műtéti ellátására. A vállízület anatómiai adottságai olyanok, hogy különös hangsúlyt kap az ízületet burkoló lágy részek védelme, a minimálisan invazív műtéti technika. Ugyanakkor az időskorban jelentkező osteoporosis megnehezíti a csontegyesítő műtétet, a szövődmények aránya a leggondosabb ellátás mellett is magas. Hat év anyagát összegyűjtve a szerzők visszarendelték operált betegeiket, fizikális és röntgenvizsgálat végzése után eredményeiket Constant-score alapján értékelték. Külön értékelték szövődményeiket a tekintetben, hogy azok milyen mértékben befolyásolhatók a műtéti módszerrel, vagy függetlenek attól. Az egyik leggyakoribb szövődmény a rögzítő fémanyagok elvándorlása, a törés ismételt elmozdulása. Ennek megakadályozására – a külföldön kifejlesztett módszereket a szerzők a hazai gyakorlat számára túlságosan költségesnek találva – a hazai gyártású Kurucz-féle menetes tűződrótot alkalmazták. Következtetéseikben megállapítják, hogy az alkalmazott implantátum a célnak megfelel, a szövetkímélő műtéti eljárástól elvárt eredményeket hozza. Mindemellett nem tekinthetjük a súlyosan poroticus vállízületi töréseket megoldottnak. A felkarfejnekrózisok magas aránya a módszertől független szövődmény. Azok kezelésére a vállízületi endoprotetika szélesebb körű alkalmazása szükséges.

Background The open Bankart technique for posttraumatic recurrent anterior instability has become the procedure of choice for patients who do not respond to nonoperative treatment. Hypothesis The open Bankart procedure renders stable and well-functioning shoulders in the long term in a large proportion of patients. Study Design Retrospective follow-up study with independent reexaminers. Methods Fifty-four patients (54 shoulders) with symptomatic, posttraumatic, recurrent anterior shoulder instability underwent an open Bankart reconstruction procedure with suture anchors. All of the patients had a Bankart lesion. Forty-seven patients (87%) were reexamined by independent observers at a mean follow-up period of 69 months (range, 48 to 114). Results The recurrence rate, including both dislocations and subluxations, was 17% (8 of 47). The median Rowe score was 90 points (range, 24 to 100) at the follow-up, and the median Constant score was 88.5 points (range, 41 to 100). External rotation in abduction was a median of 90° (range, 25° to 125°) in the involved shoulders, as compared with 97.5° (80° to 125°) in the noninjured shoulders (P < 0.0001). Conclusions We conclude that, in the long term, the open Bankart procedure resulted in an unexpectedly high number of patients with failure in terms of stability. These results emphasize the importance of performing long-term follow-up studies after surgical reconstruction for unidirectional, posttraumatic, anterior shoulder instability using any type of technique.
