Abstract Background In an anatomic shoulder replacement (aTSR) good results have been reported with the use of a stemless humeral prosthesis. In vitro a ceramic articulation with polyethylene has been shown to produce less polyethylene wear particles than with metal. This study aims to evaluate clinical and radiographic results of a stemless aTSR with a ceramic head articulating with a polyethylene glenoid component, with mid-term follow-up. Methods All patients (n = 92) in this prospective study had an aTSR utilizing a stemless humeral component with a ceramic head and a cemented double pegged cemented polyethylene glenoid component for glenohumeral osteoarthritis. Pre- and postoperative clinical evaluations at 2 years were performed using the ASES score, Constant score, SPADI score, DASH score, VAS pain score, patient satisfaction and range of motion. There was a 5-year evaluation of SPADI, ASES, pain, and satisfaction, plus radiographic assessment of glenoid component radiolucent lines and humeral osteolysis. Results Seventy-four cases (68.1 ± 7.1 years) had a five-year follow-up and demonstrated active elevation improvement from 91.3° preoperatively to 151.1° (p < 0.001). Further improvement was identified with the ASES from 41.6 to 94.3, the SPADI from 62.9 to 4.3, VAS pain from 5.6 to 0.4 (0–10), and satisfaction levels were at 96%. Sixty-two cases had no glenoid radiolucent lines with a maximum Lazarus score of 2 in one patient. Constant scores, available up to 2 years, improved significantly from 30.3 to 77.9 (p < 0.001). There was one case that required revision for glenoid loosening. Conclusions Overall, the 5-year results of this ceramic head prosthesis demonstrated good radiographic and clinical outcomes.

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.

The purpose of this study was to evaluate the clinical efficacy of the F3 Biomet plate in the treatment of 2-part displaced humeral greater tuberosity fractures. We compared the clinical outcomes of patients with displaced greater tuberosity fractures who underwent surgical treatment using an F3 plate with those of patients who were treated nonsurgically. Eleven patients with 2-part displaced humeral greater tuberosity fractures were surgically treated with use of an F3 Biomet plate, whereas 12 patients with equal injuries were treated nonsurgically. Each patient underwent follow-up for at least 1 year. We retrospectively collected data and analyzed the clinical outcomes. The Constant score and DASH score were used to assess the shoulder function, and X-rays were taken to evaluate the fracture healing. X-rays of the patients in both groups showed that the fractures achieved union after the 1-year follow-up. Patients treated surgically with an F3 plate and open reduction internal fixation had better Constant score and DASH score results for shoulder function than those treated nonsurgically. In the present study, surgical treatment of displaced humeral greater tuberosity fractures with the use of an F3 plate led to a 100% union rate and good clinical outcomes. The F3 Biomet plate can be considered an effective implant for the treatment of displaced humeral greater tuberosity fractures. The level of evidence is therapeutic III.

Abstract Background Elective implant removal (IR) accounts for up to 30% of all orthopaedic surgeries. While there is general acceptance about the need of implant removal for obvious reasons, such as infections or implant failure, little is known about the beneficial aspects in cases of minor reasons such as patients’ wish for IR. Therefore, we initiated this study to define patients’ benefit of elective implant removal following plate osteosynthesis of displaced clavicle fractures. Patients and methods Prospective evaluation of patients was conducted before implant removal and 6 weeks postoperative. Subjective and objective criteria included pain rating on a visual analogue scale (VAS) and active range of motion (ROM) pre- and 6 weeks postoperative. Functional scoring included Constant-Murley Score, DASH (Disabilities of Arm, Shoulder and Hand Score), MSQ (Munich Shoulder Questionnaire) and SPADI (Shoulder Pain and Disability Index). Results 37 patients were prospectively enrolled in this study and implant removal was performed after 16 ± 6.1 months. No re-fractures nor other complications were detected during routine follow up. Functional outcome increased through all scores (Constant score 73.3 ± 14.6 preoperative to 87.4 ± 12.0 postoperative (p = 0.000), MSQ 85.0 ± 7.3 preoperative to 91.8 ± 9.0 postoperative (p = 0.005), DASH Score 7.4 ± 8.2 preoperative to 5.7 ± 9.5 postoperative (p = 0.414), SPADI 93.4 ± 6.6 preoperative to 94.0 ± 10.1 postoperative (p = 0.734). Conclusions Discomfort during daily activities or performing sports as well as limited range of motion were the main reasons for patients’ wish for implant removal. We found increased functional outcome parameters and decreased irritation after implant removal. Therefore we suggest implant removal in case of patients’ wish and completed fracture consolidation.

Aims Highly cross-linked polyethylene (HXLPE) has greatly improved the durability of total hip arthroplasty (THA) in young patients because of its improved wear characteristics. Few studies have followed this population into the second decade, and therefore the purpose of this investigation was to evaluate the clinical outcome for THA patients 50 years of age and younger at a minimum of 15 years postoperatively. The second purpose was to evaluate the radiological findings secondary to wear or mechanical failure of the implant. Methods Between October 1999 and December 2005, 105 THAs were performed in 95 patients (53 female, 42 male) aged 50 years and younger (mean 42 years (20 to 50)). There were 87 patients (96 hips) that were followed for a minimum of 15 years (mean 17.3 years (15 to 21)) for analysis. Posterior approach was used with cementless fixation with a median head size of 28 mm. HXLPE was the acetabular bearing for all hips. Radiographs were evaluated for polyethylene wear, radiolucent lines, and osteolysis. Results Clinical outcomes showed significant improvement of mean Harris Hip Scores from 52.8 (SD 13.5) preoperatively to 94.8 (SD 7.6) postoperatively. One hip was revised for recurrent instability, and there were no infections. No hips were revised for mechanical loosening or osteolysis. Mean polyethylene linear wear was 0.04 mm/year and volumetric wear was 6.22 mm3/year, with no significant differences between head size or material. Osteolysis was not present in any of the hips. Conclusion The use of HXLPE in THA for patients aged 50 years and younger has performed exceptionally well without evidence of significant wear causing mechanical loosening or necessitating revision. The radiolucent lines of the acetabular component must be followed to determine the prognostic significance. This investigation represents the longest clinical follow-up of a large, consecutive cohort of patients aged 50 years or younger with THA using HXLPE. This long-term analysis found negligible polyethylene wear, no incidence of aseptic loosening, and excellent clinical outcomes at and beyond 15 years of follow-up.

Aims Controversy about the use of an anatomical total shoulder arthroplasty (aTSA) in young arthritic patients relates to which is the ideal form of fixation for the glenoid component: cemented or cementless. This study aimed to evaluate implant survival of aTSA when used in patients aged < 60 years with primary glenohumeral osteoarthritis (OA), and to compare the survival of cemented all-polyethylene and cementless metal-backed glenoid components. Materials and Methods A total of 69 consecutive aTSAs were performed in 67 patients aged < 60 years with primary glenohumeral OA. Their mean age at the time of surgery was 54 years (35 to 60). Of these aTSAs, 46 were undertaken using a cemented polyethylene component and 23 were undertaken using a cementless metal-backed component. The age, gender, preoperative function, mobility, premorbid glenoid erosion, and length of follow-up were comparable in the two groups. The patients were reviewed clinically and radiographically at a mean of 10.3 years (5 to 12, sd 26) postoperatively. Kaplan–Meier survivorship analysis was performed with revision as the endpoint. Results A total of 26 shoulders (38%) underwent revision surgery: ten (22%) in the polyethylene group and 16 (70%) in the metal-backed group (p < 0.0001). At 12 years’ follow-up, the rate of implant survival was 74% (sd 0.09) for polyethylene components and 24% (sd 0.10) for metal-backed components (p < 0.0002). Glenoid loosening or failure was the indication for revision in the polyethylene group, whereas polyethylene wear with metal-on-metal contact, instability, and insufficiency of the rotator cuff were the indications for revision in the metal-backed group. Preoperative posterior subluxation of the humeral head with a biconcave/retroverted glenoid (Walch B2) had an adverse effect on the survival of a metal-backed component. Conclusion The survival of a cemented polyethylene glenoid component is three times higher than that of a cementless metal-backed glenoid component ten years after aTSA in patients aged < 60 years with primary glenohumeral OA. Patients with a biconcave (B2) glenoid have the highest risk of failure. Cite this article: Bone Joint J 2018;100-B:485–92.

Background: Superior capsular reconstruction (SCR) represents a new option for the treatment of irreparable rotator cuff tears. Purpose/Hypothesis: This study aimed to evaluate the clinical and radiologic outcomes of SCR and compare them with the outcomes of partial repair (PR) of the infraspinatus tendon. The hypothesis was that there would be no significant differences between the clinical and radiologic outcome parameters of SCR and PR after a minimum follow-up of 2 years. Study Design: Cohort study; Level of evidence, 3. Methods: Of 21 patients who underwent SCR, 20 patients were matched in a 1:1 ratio according to sex, age, and tear configuration with 20 of 60 patients who had undergone PR; all patients were prospectively evaluated for a minimum follow-up of 2 years. The investigated outcome measures included the Constant score; Western Ontario Rotator Cuff (WORC) index; Disabilities of the Arm, Shoulder and Hand (DASH) score; and radiologic analysis of acromiohumeral distance (AHD) and humeral head centralization (HHC). Results: There were no differences in the demographic data between the SCR and PR groups. The mean age of both groups was 62.3 years (range, 47-79 years), the mean tear configuration was Bateman 3.0 and Patte 2.8, and the mean follow-up period was 29.4 months (range, 24-53 months). At final follow-up, no significant differences were seen between the SCR and PR groups with regard to Constant score (77.1 vs 82.7), age- and sex-adapted Constant score (85.5% vs 91.4%), DASH score (15.6 vs 7.8), or WORC index (81.1 vs 90.4). No significant differences in the AHD or HHC were seen between the groups. The reoperation rate was 4.8% (1/21) in the SCR cohort and 15% (9/60) in the PR cohort. Conclusion: Both SCR and PR resulted in significant improvements in patient-reported outcomes at 2-year follow-up, with no significant differences in clinical outcomes between the 2 techniques. Further follow-up is needed to determine whether there are long-term differences in HHC and development of cuff tear arthropathy. Further investigations should also focus on the cost-effectiveness of the respective procedures.

Background: Due to the rotator cuff retear after being surgically repaired, some strategies have been developed. The authors verified that the possibility of polyetheretherketone (PEEK) vented anchors promoted a better clinical and healing process than PEEK solid anchors. Methods: A prospective and randomized study was designed with 38 patients treated with PEEK anchors, 18 of whom with vented anchors and 20 with solid ones. Demographic, clinical and radiologic data were collected before and during surgery (time 0) and at 12 months of follow-up. Results: In the final follow-up (12 months), there was no difference in the visual analogic scale (VAS) scale between groups (1.7 points vs 1.9 points; p = 0.731), neither in the DASH score (34.2 points vs 23.9 points; p = 0.268), nor in absolute Constant score (76.9 points vs 77.3 points; p = 0.910). In MRI, 10 patients had their cuff tear healed in the vented group and 15 in the solid group (p = 0.173). Conclusion: The new designed vented anchors do not add any advantage when compared to solids ones, at least within the first year after surgery.

<p class="abstract">Shoulder instability, though often seen in younger individuals it can also occur in the elderly. Shoulder instability in the elderly is often missed and definitive management gets delayed. Treatment delay has a significant influence on the choice of surgical procedure and its functional outcome. We report a 77 year old female who presented with a missed anterior dislocation of the glenohumeral joint. She had undergone an open Latarjet procedure for shoulder instability eight months before her presentation. Considering her age, humeral head bone defects, rotator cuff tear and degenerative changes in the joint we opted for a Reverse Shoulder Replacement in her. The patient now has a pain free, stable and mobile shoulder joint. Her pre-operative Constant score was 11 which improved to 67 at 6 months follow up. Now after 12 months follow up, she has active flexion up to 150°, abduction- 90°, external rotation- 10°, internal rotation- 30<sup>0</sup> and extension- 50°. Reverse shoulder replacement is a viable treatment option for chronic locked shoulder dislocations with concomitant rotator cuff lesions. Though there is a concern about failure of the glenoid component due to bone defects, RSA is still preferable in elderly patients with low functional demand.</p>

INTRODUCTION Recognising that timely dissemination of information in the orthopaedic community was important and in the absence of any national guidelines for shoulder arthroplasty, the Scottish shoulder arthroplasty registry, a voluntary registry, was started in 1996. The goals of the registry were to assess contemporary practice, provide a benchmark against which surgeons could compare their practice, identify risk factors for a poor outcome, and to improve outcomes through continuous feedback to the participating surgeons. PATIENTS AND METHODS A standardised proforma was used to collect information on the diagnostic and demographic data, type of procedure performed, type of implant used, any associated procedures performed in conjunction with the arthroplasty, and peri-operative complications. Postoperative pain, activity and patient satisfaction were assessed annually using another standardised proforma. RESULTS Twenty surgeons have contributed to the register and 451 shoulder arthroplasties were registered over a 5-year period. Of patients, 23.2% were male and 76.8% female. The mean age was 65 years (range, 37–90 years). Shoulder arthroplasty was commonly performed for rheumatoid arthritis followed by trauma, osteoarthritis and avascular necrosis of the humeral head. Overall, 397 (88%) patients had a hemi-arthroplasty and 54 (12%) had a total shoulder replacement. Of the 54 cases that had a glenoid replacement, 28 were performed for inflammatory arthritis, 21 for osteoarthritis and 5 were for revisions. The humeral component was cemented in 204 (45%) cases, 160 of whom had a shoulder replacement for trauma. The glenoid component was cemented in 48 (89%) cases. Cross referencing our data with the figures of the actual number of shoulder arthroplasties performed, however, indicated that our registry at best collected only 53% of all the shoulder arthroplasties performed in Scotland annually. CONCLUSIONS The value of a joint registry is dependent on the accuracy and completeness of the data entered. Our registry, therefore, fails as an implant registry. We believe that compliance for data registration can only be ensured if dedicated data collection staff are employed to co-ordinate the data collection and collation process.
