Background: Heterotopic ossification (HO) is a frequent radiographic finding after total ankle arthroplasty (TAA), but its clinical relevance, diagnostic criteria, and prognostic implications remain uncertain. This systematic review summarizes current evidence on HO incidence, distribution, severity, risk factors, clinical impact, and diagnostic/prognostic value to inform surgical decision-making regarding approach, implant design, and revision strategies. Methods: A systematic review was conducted according to PRISMA guidelines using PubMed, Web of Science, and Scopus databases and the following search string “heterotopic ossification”AND“ankle” (February 2015–February 2025). Twenty-two studies were included, most of which were retrospective and varied in methodological quality. Data were extracted on HO incidence, severity, clinical relevance, and factors associated with diagnosis and management. Results: HO incidence varied widely across studies. No significant associations were found betweenHO and surgical variables such as approach (all studies used the anterior approach) or coronal alignment. HO presence did not consistently correlate with reduced postoperative range of motion and radiographic follow-up duration. Implant design appeared to influence anatomical distribution in some comparative studies, though without statistical significance. Reoperations specifically for HO excision were rare and mainly performed for mechanical complications (impingement or osteolysis) rather than HO severity itself. Conclusions: Although HO is a frequent finding after TAA, its clinical impact appears limited and largely unpredictable. Diagnostic tools are currently limited to conventional radiography, and no reliable prognostic markers exist. Further high-quality studies are needed to define standardized diagnostic criteria and clarify the prognostic role of HO in long-term outcomes....
A 75-year-old patient was transferred to the oncology department due to the discovery of a large pelvic tumor compressing the femoral neurovascular bundle suspected to be of malignant origin. Further investigation revealed a rare complication related to a 27-year-old total hip arthroplasty (THA). The final diagnosis was a severe adverse local tissue reaction (ALTR) resulting from excessive implant wear—first from a metal-on-metal (MoM) bearing and later exacerbated by a revision to a metal-on-polyethylene (MoP) articulation. The clinical course was further complicated by periprosthetic joint infection (PJI). The patient underwent extensive tumor-like mass resection followed by two-stage revision arthroplasty. Despite these interventions, infection persisted, ultimately necessitating joint resection. This case highlights the rare but serious convergence of dreaded orthopedic complications (ALTR and PJI). It underscores the diagnostic challenge posed by wear-induced pseudotumors, which are rare even among arthroplasty specialists and are often unfamiliar to oncologists. This case illustrates the importance of early orthopedic evaluation, maintaining a high index of suspicion in atypical presentations, and invites further discussion about the interplay between ALTRs and infection risk in arthroplasty patients....
Background: We aimed to analyze radiographic sagittal balance parameters in patients who underwent a TLIF procedure for single-level degenerative spondylolisthesis with a mean follow-up of 8.6 years and to determine whether lumbar lordosis affects long-term clinical outcomes. Methods: This prospective study included 32 patients who underwent single-level TLIF surgery for degenerative spondylolisthesis. Radiographic analysis of sagittal balance parameters and clinical examination including Oswestry Disability Index (ODI) scores were performed preoperatively, postoperatively, and at the last follow-up. A minimal clinically important difference threshold of 30% was accepted as clinically relevant. Results: Mean postoperative lumbar lordosis (LL) and segmental lordosis (SL) failed to improve postoperatively; nevertheless significant improvements in short- and long-term postoperative ODI scores were demonstrated (p < 0.001). Thoracic kyphosis (TK) and global sagittal balance parameters shifted anteriorly after 8.6 years (p < 0.001), but this increase did not affect clinical outcomes. Conclusions: Adequate decompression and solid bone fusion are foremost required to achieve improved long-term clinical outcomes in singlelevel TLIF procedures. In our studied cohort, failure to improve lordosis did not impair clinical outcomes postoperatively. With aging, thoracic kyphosis and anterior malalignment increase, and after 8.6 years, clinical improvements are starting to become insignificant....
Background: This study examines current trends in Canada using data from the Canadian Joint Replacement Registry (CJRR) and includes a national survey to understand the varied uptake of cement for femoral stem fixation. Methods: The survey was available online and the website link was distributed to all orthopaedic surgeons through the Canadian Orthopaedic Association between September and December 2022. The CJRR obtained data from the Canadian Institute for Health Information (CIHI), and information pertaining to patients 55 years of age and older who underwent hemiarthroplasty for hip fracture in Canada between April 2017 and March 2022 was used. Results: Most respondents practiced in an academic community setting (52%). Only 53% of respondents reported using cement, and 71% indicated that cemented fixation was the best practice. The main reasons for using uncemented stems were less operative time (23%), cement disease concerns (11%), and surgeons’ comfort (10%). Similarly, CJRR data showed only 51% cemented fixation among 42,386 hemiarthroplasties performed between 2017 and 2022. The proportion of cemented implants varied by province, but overall, the increase in the use of cement from 2017 to 2022 was from 42.9% to 57.7%. Conclusions: This study demonstrates variability in the use of cement for femoral fixation despite solid evidence showing improved outcomes using cement. Some of the main reasons in favour of uncemented stems include operative time, surgical training, and concerns about cement disease. Establishing clear position statements and guidelines supporting cemented fixation may be prudent to build universal consensus on this practice....
Background: There are differing opinions in the literature regarding the optimal treatment modality for adolescents with completely displaced, complex clavicle fractures. This study aims to determine outcome differences between surgical and non-surgical treatment for adolescent Z-type clavicle fractures and to ascertain if differences exist in outcomes between the two interventions. Methods: This was a single-center, retrospective chart review performed at a level 1 trauma center. Inclusion criteria included pediatric patients ages 12 to 16 years who presented with a comminuted, displaced clavicle shaft fracture with a comminuted fragment more than 1 cm in length and were treated either operatively or nonoperatively between January 2019 and December 2022. The outcomes were radiographic union status (i.e., union versus non-union versus malunion), follow-up period, shoulder range of motion, return to athletic activities, and patient reported pain level. Results: Of the 24 patients, 11 were treated surgically and 13 non-surgically. Patients who were treated surgically were more likely to be older (mean 1.5 years, p = 0.039) and have a longer follow-up by 9 months average duration compared to the cohort treated non-surgically (p = 0.0009). There was no significant difference between patient reported pain, radiographic union status, return to athletic activity, or shoulder range of motion between the cohorts. The small sample size and retrospective study design limits the statistical power of our results. Conclusions: The decision between treating these complex fractures operatively versus nonoperatively should be left to a lengthy discussion between the surgeon, parents, and the patient....
Background: Severe glenoid bone loss presents a major challenge in both primary and revision reverse shoulder arthroplasty (RSA). Standard implants often fail to achieve reliable fixation in these cases. Custom-made, 3D-printed glenoid components have emerged as a potential solution, offering anatomically tailored fit and fixation. This study evaluates the clinical and radiographic outcomes of custom-made glenoid implants in managing severe glenoid bone loss. Methods: A retrospective, multicenter study was conducted on 23 shoulders (11 primary and 12 revision RSAs) that received a custom-made glenoid component using the Enovis ProMade System (San Daniele del Friuli, Udine, Italy) between 2017 and 2022, with a minimum follow-up of 24 months. Preoperative planning utilized CT-based 3D modeling to design implants with patient-specific instrumentation. Clinical outcomes (ROM, pain, Constant–Murley score) and radiographic results were assessed. Statistical comparisons were made between primary and revision groups. Results: Both groups demonstrated significant improvements in shoulder mobility, pain relief, and Constant– Murley scores (all p < 0.001), with no significant differences between primary and revision groups in delta scores. Radiographically, no loosening was observed, with minimal radiolucent lines and low complication rates. Four cases of instability occurred, all in the revision group, with only one requiring conversion to hemiarthroplasty. No differences in radiographic outcomes were observed between groups. Conclusions: Custom-made glenoid implants provide a reliable solution for severe glenoid bone loss in both primary and revision RSA, yielding consistent functional improvement and implant stability. Further prospective studies with larger cohorts and long-term follow-up are warranted to confirm these findings and assess cost-effectiveness....
