Aims: The modes of failure of bipolar arthroplasty and outcomes following revision surgery have not been described. Methods: 7 patients (2f, 5m) who previously underwent bipolar arthroplasty were treated with revision surgery. Patient self-assessment was obtained pre- and postoperatively with a satisfaction survey, SF-36, SST, ASES scores, and preoperative/postoperative x-rays. Results: Modes of failure included rotator cuff failure 6/7, superior arch deficiency (4/7) and glenoid erosion (3/7). Revision surgery was performed to reconstruct instability, resurface eroded bone and repair available rotator cuff tissue. Anterior superior arch deficiencies were all revised to a semiconstrained reverse prosthesis. Other patients (3/7) were revised to unconstrained TSA. In this group, additionally soft tissue reconstructions were performed. ASES scores improved from 33 preoperatively to 55.5 postoperatively (P <

Total shoulder arthroplasty (TSA) and Reverse Total shoulder arthroplasty (RSA) are two of the most performed shoulder operations today. Traditionally postoperative rehabilitation included a period of immobilisation, protecting the joint and allowing time for soft tissue healing. This immobilisation period may significantly impact a patient's quality of life (Qol)and ability to perform activities of daily living (ADL's). This period of immobilisation could be safely avoided, accelerating return to function and improving postoperative QoL. This systematic review examines the safety of early mobilisation compared to immobilisation after

Aims. The aim of this study was to investigate the effects of preoperative bisphosphonate treatment on the intra- and postoperative outcomes of arthroplasty of the shoulder. The hypothesis was that previous bisphosphonate treatment would adversely affect both intra- and postoperative outcomes. Patients and Methods. A retrospective cohort study was conducted involving patients undergoing arthroplasty of the shoulder, at a single institution. Two patients with no previous bisphosphonate treatment were matched to each patient who had received this treatment preoperatively by gender, age, race, ethnicity, body mass index (BMI), and type of arthroplasty. Previous bisphosphonate treatment was defined as treatment occurring during the three-year period before the arthroplasty. The primary outcome measure was the incidence of intraoperative complications and those occurring at one and two years postoperatively. A total of 87 patients were included: 29 in the bisphosphonates-exposed (BP. +. ) group and 58 in the non-exposed (BP. -. ) group. In the BP. +. group, there were 26 female and three male patients, with a mean age of 71.4 years (51 to 87). In the BP. -. group, there were 52 female and six male patients, with a mean age of 72.1 years (53 to 88). Results. Previous treatment with bisphosphonates was positively associated with intraoperative complications (fracture; odds ratio (OR) 39.40, 95% confidence interval (CI) 2.42 to 6305.70) and one-year postoperative complications (OR 7.83, 95% CI 1.11 to 128.82), but did not achieve statistical significance for complications two years postoperatively (OR 3.45, 95% CI 0.65 to 25.28). The power was 63% for complications at one year. Conclusion. Patients who are treated with bisphosphonates during the three-year period before

The Oxford Shoulder Score (OSS) is a 12-item measure commonly used for the assessment of shoulder surgeries. This study explores whether computerized adaptive testing (CAT) provides a shortened, individually tailored questionnaire while maintaining test accuracy. A total of 16,238 preoperative OSS were available in the National Joint Registry (NJR) for England, Wales, Northern Ireland, the Isle of Man, and the States of Guernsey dataset (April 2012 to April 2022). Prior to CAT, the foundational item response theory (IRT) assumptions of unidimensionality, monotonicity, and local independence were established. CAT compared sequential item selection with stopping criteria set at standard error (SE) < 0.32 and SE < 0.45 (equivalent to reliability coefficients of 0.90 and 0.80) to full-length patient-reported outcome measure (PROM) precision.Aims

Introduction. The impact of prior ipsilateral shoulder surgery on outcomes following total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) is unknown. The purpose of this study was to determine the impact of prior shoulder surgery on patients undergoing TSA and RSA compared to patients without prior shoulder surgery. The hypothesis was that patients undergoing arthroplasty after prior ipsilateral shoulder surgery would have inferior outcomes with higher complication rates compared to patients undergoing arthroplasty without having undergone prior surgery. Materials and Methods. Seven-hundred fifteen consecutive patients undergoing TSA or RSA between 1/2010 and 5/2014 with a minimum 2-year follow-up were prospectively analyzed. All patients were evaluated with the American Shoulder and Elbow Society (ASES), Simple Shoulder Test (SST), Functional Score, Visual Analog Scale (VAS) outcomes assessments, as well as with physical examination including range of motion assessments. Outcomes in patients undergoing prior ipsilateral shoulder surgery (PS group) were compared to those in patients without history of prior surgery (NPS group). Statistical analysis was performed using one-way univariate and multivariate analysis of covariates (ANCOVA/MANCOVA) adjusting for age, Whitney-Mann U tests, and Chi-square or Fisher's exact test, with P<0.05 considered significant. Results. Of the 715 patients, 506 (263 TSA, 243 RSA) were available for analysis (71% follow-up rate). A total of 144 patients (29%) underwent an average of 2.0±1.1 ipsilateral shoulder surgeries, prior to arthroplasty while 362 (71%) did not undergo prior surgery. In the PS Group, rotator cuff repair (RCR) accounted for 67% of the prior surgeries. PS group patients were significantly younger at the time of arthroplasty compared to the NPS group (61.6±10.2 vs. 68.2±8.6 years, P=0.035). At an average follow-up of 42.8±16.4 months, both groups had significant improvements in ASES, SST, and VAS outcomes scores and range of motion values (P<0.05 for all). All outcomes scores in the PS group were significantly lower compared to the NPS group (P≤0.005 for all). Within the PS group, there were no significant differences detected in outcome scores or magnitudes of change in outcomes between patients undergoing RCR or any other procedure. There were 41 total complications (8.1%) and 17 total reoperations (3.4%) following

Total shoulder arthroplasty (TSA) and reverse
Rates of reverse total shoulder arthroplasty (rTSA) continue to grow. Glenoid bone loss and deformity remains a technical challenge to the surgeon and may reduce improvements in patients’ outcomes. However, there is no consensus as to the optimal surgical technique to best reconstruct these patients’ anatomy. This review aims to compare the outcomes of glenoid bone grafting versus augmented glenoid prostheses in the management of glenoid bone loss in primary reverse total shoulder arthroplasty. This systematic review and meta-analysis evaluated study-level data in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. We performed searches of Medline (Ovid), Embase (Ovid), and PubMed from their dates of inception to January 2022. From included studies, we analyzed data for preoperative and postoperative range of motion (ROM), patient-reported functional outcomes, and complication rates.Aims

Introduction:
Proximal humeral fractures (PHFs) are common. There is increasing evidence that most of these fractures should be treated conservatively. However, recent studies have shown an increase in use of operative treatment. The aim of this study was to identify the trends in the incidence and methods of treatment of PHFs in Finland. The study included all Finnish inhabitants aged ≥ 16 years between 1997 and 2019. All records, including diagnostic codes for PHFs and all surgical procedure codes for these fractures, were identified from two national registers. Data exclusion criteria were implemented in order to identify only acute PHFs, and the operations performed to treat them.Aims

Introduction and Objective. In recent years, along with the extending longevity of patients and the increase in their functional demands, the number of annually performed RSA and the incidence of complications are also increasing. When a complication occurs, the patient often needs multiple surgeries to restore the function of the upper limb. Revision implants are directly responsible for the critical reduction of the bone stock, especially in the shoulder. The purpose of this paper is to report the use of allograft bone to restore the bone stock of the glenoid in the treatment of an aseptic glenoid component loosening after a reverse

To determine whether pre-operative cessation of anticoagulant or antiplatelet medication is necessary for patients undergoing total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA). A prospectively maintained database was used to identify 213 consecutive patients treated with TSA or RTSA performed by a single surgeon across 3 centres. This cohort included 24 patients on an anticoagulant agent (warfarin, apixaban, rivaroxaban, dabigatran), 52 patients on an antiplatelet agent (aspirin, clopidogrel), and a control group of 137 patients not on anticoagulant or antiplatelet medication. Patients on anticoagulant or antiplatelet medications continued these agents peri-operatively. Outcomes included haemoglobin drop, intra-operative blood loss, operative time, transfusion requirements and post-operative complications. The mean age of the cohort was 74.3 years (range 47 – 93) and 75 (35.2%) of the patients were male. TSA was performed in 63 cases and RTSA in 150 cases. The mean haemoglobin drop in the control group was 17.3 g/L, compared to 19.3 g/L in the anticoagulant group (p = 0.20) and 15.6 g/L in the anti-platelet group (p = 0.14). The mean intra-operative blood loss in the control group was 107.8 mL, compared to 143.0 mL in the anticoagulant group (p = 0.03) and 134.3 mL in the anti-platelet group (0.02). The mean operative time in the control group was 49.3 minutes, compared to 47.1 minutes in the anticoagulant group (p = 0.56) and 50.3 minutes in the anti-platelet group (p = 0.78). Post-operatively no patients developed a wound infection or haematoma requiring intervention. Three patients not on anticoagulant or antiplatelet medication developed pulmonary embolism. Continuing anticoagulant or antiplatelet medication was associated with higher intra-operative blood loss, but produced no statistically significant differences in haemoglobin drop, operative time, transfusion requirements or post-operative complications. We now do not routinely stop any anticoagulant or antiplatelet medication for patients undergoing total shoulder arthroplasty.
Introduction and Objective. The aim of this study was to evaluate whether CT-based pre-operative planning, integrated with intra-operative navigation could improve glenoid baseplate fixation and positioning by increasing screw length, reducing number of screws required to obtain fixation and increasing the use of augmented baseplate to gain the desired positioning. Reverse total shoulder arthroplasty (RSA) successfully restores shoulder function in different conditions. Glenoid baseplate fixation and positioning seem to be the most important factors influencing RSA survival. When scapular anatomy is distorted (primitive or secondary), optimal baseplate positioning and secure screw purchase can be challenging. Materials and Methods. Twenty patients who underwent navigated RSA (oct 2018 and feb 2019) were compared retrospectively with twenty patients operated on with a conventional technique. All the procedures were performed by the same surgeon, using the same implant in cases of eccentric osteoarthritis or complete cuff tear. Exclusion criteria were: other diagnosis as proximal humeral fractures, post-traumatic OA previously treated operatively with hardware retention, revision
Background. Glenoid baseplate fixation for reverse
Reverse total shoulder arthroplasty (rTSA) can be used in complex cases when the glenoid requires reconstruction. In this study, a baseplate with composite bone autograft and a central trabecular titanium peg was implanted, and its migration was assessed for two years postoperatively using radiostereometric analysis (RSA). A total of 14 patients who underwent a rTSA with an autograft consented to participate. Of these, 11 had a primary rTSA using humeral head autograft and three had a revision rTSA with autograft harvested from the iliac crest. The mean age of the patients was 66 years (39 to 81). Tantalum beads were implanted in the scapula around the glenoid. RSA imaging (stereographic radiographs) was undertaken immediately postoperatively and at three, six, 12, and 24 months. Analysis was completed using model-based RSA software. Outcomes were collected preoperatively and at two years postoperatively, including the Oxford Shoulder Score, the American Shoulder and Elbow Score, and a visual analogue score for pain. A Constant score was also obtained for the assessment of strength and range of motion.Aims
