Background: Partial tears of the rotator cuff tendons are a common cause of shoulder pain and functional limitation among adults. Conservative management often provides only partial relief in chronic cases. Platelet-rich plasma (PRP) and hyaluronic acid (HA) injections have shown promising effects in tendon regeneration, pain reduction, and improved function. PRP delivers growth factors that promote healing and reduce inflammation, while HA maintains tendon elasticity and inhibits inflammatory cytokines. Combining PRP and HA may produce synergistic therapeutic effects; however, data on their combined use in Mongolian patients remain limited. Objective: To evaluate and compare the clinical outcomes of PRP, HA, and combined PRP + HA injections in patients with rotator cuff tendon disorders. Material and Method: Sixty patients diagnosed with rotator cuff pathology (ICD code M75.1) at the National Trauma and Orthopedic Research Center of Mongolia between June 2024 and June 2025 were enrolled. Participants were randomly divided into three groups: PRP + HA (n=20), PRP only (n=20), and HA only (n=20). Each patient received three ultrasound-guided injections at two week intervals. Clinical outcomes were assessed using pain score (VAS), range of motion (ROM), Constant–Murley score, and the Shoulder Pain and Disability Index (SPADI) at baseline, 4, 12, and 24 weeks. Data were analyzed using ANOVA, with p < 0.05 considered significant.
Ethics Approval. “Ach” Medical University, Ethics Committee Resolution, Date: June 30, 2023 Resolution No: 23/02/12, Location: Ulaanbaatar, Mongolia Results: The PRP+HA group demonstrated the greatest improvements across all parameters. Pain decreased by 60% at 12 weeks, and ROM increased by 20–25% from baseline (p<0.05). SPADI scores improved from 63.2 to 21.3 at 24 weeks (p < 0.001). No serious adverse effects occurred. Conclusion Combined PRP and HA injections significantly enhance pain relief, mobility, and shoulder function compared to either treatment alone. This combined therapy is safe, effective, and represents a promising approach for managing rotator cuff tendon disorders.

After low back pain and knee pain, shoulder pain has been estimated to be the third most common musculoskeletal presentation in primary care. The prognosis for people presenting with musculoskeletal shoulder pain varies widely between individuals with, on average, 50% of people with shoulder pain still reporting symptoms 6months after presenting in primary care. In addition to pain, functional disabilities are common and can interfere with work, hobbies, social, and sporting activities and may also be associated with psychological distress and reduced quality of life. Shoulder pain consequences generate high costs to society.

Introduction Irish surgeon Abraham Coll bone lower forearm Call an end in 1814 reports about the location extension breaks, fractures, called colles fractures. It is common fractures account for 10-20% of the total respectively fracture, the bottom end 75% of bone fracture forearm. Number of elderly patients in developed countries has increased, an increasing number of these refractive growth. In 2001, in the cases of 640,000 fracture United States forearm bone bottom colles. Purpose Study for the influence of risk factors in bone setting treatment Colles fracture Objectives: 1. Forearm bone assessment bottom Colles displaced, some of the causes which affect nondisplaced fractures, depending upon risk factors 2. Forearm bone to assess what the lower end Colles healing some of the risk factors that may affect the fracture Materials and Methods Trauma and Orthopedic research studies involving the term “Emergency Department” at the forearms of 80 people age 5-76 bone treatment in patients who received the peace at the lower end Colles fracture the national center. Respondents grooming, nongrooming divided into 2 groups, which may not be received and confirmed by refractive index difference in X-ray. To analyze the data elements of descriptive statistics was used (mean, standard deviation, percentage distribution). As a result of calculating the difference between the data expressed as a percentage Use Pearson’s chi-squares method. If using T-test method to calculate the difference between the data and the P value less than 0.05 considered statistically accurate. Calculating the relationship between the power of the data evaluated the relationship using spearman correlation coefficient. Result Some of the causes and risk factors are compared between groups, Colles difference nondisplaced fracture purity (r=0.18, p=0.21) or a weak relationship, Colles difference, compared to the nondisplaced fracture the use of calcium supplementation (r=0.21, p=0.06) associations, Colles difference, gender nondisplaced fracture compared (r=0.28, p=0.01) weaknesses related were statistically significant. Conclusion 1. Colles difference nondisplaced fractures when used in alcohol risk factors affect the injury took place, and menopause are diagnosed with osteoporosis, previous calcium intake is associated with weak damage. 2. Colles difference refraction healing has 24-hour loss of time covered detonations often bear physical therapy show his hand and damaged a hospital that affect healing.

Introduction: In 1814 Irish surgeon Abraham Coll first introduced distal radial bone fracture in clinical practice as a colles fracture. It is one of the most common fractures account for 10-20% of the total respectively fracture. Case of Colles fracture has being increased in the developed country year by year besides the increasing number of elderly patients. Depending on severity displaced of the fracture, management includes closed reduction or surgical procedure. The aim of study was to study result of risk factors that influence the closed reduction management of the Colles fracture. Materials and Methods: From hospital based population 80 patients aged between 5-76 years (mean age 47.31 years, male 61.25%, female 38.7%) were recruited by cross sectional and randomized method. Participants were divided into displaced and non-displaced groups which confirmed by refractive index difference on X-ray. Results: The risk factors that influence the colles fracture closed reduction management was osteoporosis (p=0.38), menopause (r=0.18, p=0.27), calcium supplement intake (r=0.21, p=0.05), received hospital care in 24 hour (p=0.39), apply plaster (p=0.64), hand sling immobilizer brace (p=0.5) and physical therapy (p=0.5). Conclusion: Osteoporosis and menopause were the risk factors that influenced the closed reduction management of Colles fracture. The patient cases that not receiving emergency medical care in first 24 hours, not applying plaster, not using the hand sling immobilizer brace and not receiving physical therapy was risk factors for extending the closed reduction management of the Colles fracture.
