Grade 3 proximal humerus giant cell tumours are uncommon and the results of their surgical management with prosthetic replacement are not well established. We retrospectively studied patients with grade 3 giant cell tumours of proximal humerus treated with excision and prosthetic replacement from January 2009 and December 2018. We identified 13 patients who underwent tumour excision and prosthetic replacement. There were 7 (53.8%) men and 6 (46.2%) women. The mean age at diagnosis was 30.4 years (range 16-48 years). The mean follow-up period was 72.2 months (range 24-132). Margins were positive in 4 (30.8%) patients, ≤ 1 mm in 8 (61.5%) patients, and negative in 1 (7.7%) patient. Local recurrence was seen in 2 (15.4%) patients. 1 out of 2 (50%) patients with local recurrence had pathological fracture at presentation and margins were positive in both (100%) patients. There were 3 (23.1%) complications-1 patient with joint subluxation, 1 patient with fracture post trauma, and 1 patient with surgical site infection. The mean overall Musculoskeletal Tumour Society score was 24 out of 30 (range 21-29). Resection of grade 3 proximal humerus giant cell tumour and reconstruction with prosthesis results in low recurrence rate and good functional outcome and is a valuable treatment option for such tumours.

5-Year Mortality After Complex Displaced Proximal Humerus Fractures in Elderly Patients: Conservative Versus Reverse Total Shoulder Arthroplasty.

The mortality rate following proximal humerus fractures (PHFs) in elderly patients is increased, but currently, there are no medium-term studies comparing mortality following treatment with Reverse Total Shoulder Arthroplasty (RTSA) to non-surgical treatment. This retrospective study compares two groups of elderly patients (aged 75 to 95 at the time of injury) who were diagnosed with PHFs. A total of 79 patients (mean age: 83.

Background: Rich data on diverse patients and their treatments and outcomes within Electronic Health Record (EHR) systems can be used to generate real world evidence. A health recommender system (HRS) framework can be applied to a decision support system application to generate data summaries for similar patients during the clinical encounter to assist physicians and patients in making evidence-based shared treatment decisions.
Objective: A human-centered design (HCD) process was used to develop a HRS for treatment decision support in orthopaedic medicine, the Informatics Consult for Individualized Treatment (I-C-IT).

Introduction And Importance: Multifocal fractures in a single upper extremity represent a significant clinical challenge, often resulting from high-energy impacts such as motor vehicle accidents or severe falls. These injuries require complex, multifaceted approaches in management, spanning initial acute care to long-term rehabilitation. This paper examines the complexities of diagnosing, treating, and rehabilitating multifocal upper extremity fractures, highlighting the importance of timely intervention and a multidisciplinary approach to maximize functional recovery, minimize long-term disability and the prognosis.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

Objective: To compare the clinical efficacy of the minimally invasive lateral shoulder approach and deltopectoral space approach in the treatment of proximal humerus fractures.
Methods: The clinical data of 95 patients with proximal humerus fractures admitted to the hospital from June 2018 to June 2023 were retrospectively collected. Forty-four patients were treated with a minimally invasive lateral shoulder approach (study group), and 51 patients were treated with a deltopectoral space approach (control group).
