In adults, they account roughly for 4% of all fractures. Treatment of these fractures varies depending on their severity. No uniform guidelines have been published to date for the treatment of severely comminuted fractures.</p><p><strong>Material and methods: </strong>The study included 16 patients who underwent on-table reconstruction, with a mean age of 49 years. Half of the cases involved Mason type III fractures, while the other half involved Mason type IV fractures. The 2.0mm (1.5mm) LCP system was used for osteosynthesis. Dislocated fragments were treated using the on-table method, i.e., reconstruction on the instrument table. The patients were followed up for 54 months on average. The results were evaluated using the Mayo Elbow Performance Index (MEPI), and X-ray images were assessed (healing, degenerative changes).</p><p><strong>Results: </strong>According to MEPI, in 6 patients excellent results were achieved, in 5 patients good results were observed, and in 5 patients fair results were reported. No patient showed poor results. The range of motion in the operated elbow was 125-140° for flexion, 0-45° for extension, and the rotation (supination and pronation) was 45-90°. Complications included partial aseptic necrosis in three cases, non-union and implant failure in two cases. No neurological, vascular, or infectious complications were observed. Revision surgery was performed in 10 patients, with the most common reason being simple removal of the material (7 cases). Moreover, in one case the implantation of a cervicocapital endoprosthesis for non-union was performed.</p><p><strong>Discussion: </strong>Humeroradial joint reconstruction is particularly important in unstable fractures. In the past, when open reduction and internal fixation (ORIF) were impossible, radial head excision according to Mason was used. This procedure, however, often resulted in subluxation, arthrosis, and persistent pain. The \"on-table\" reconstruction method for comminuted fractures of the radial head was first described by Businger and is considered a promising alternative with a low risk of head necrosis, which is also confirmed by other published studies. Even though the radial head replacement in comminuted fractures provides excellent short-term outcomes, complications such as humeral erosion, limited range of motion and pain, or the development of degenerative changes in the joint occur in the medium to long term.</p><p><strong>Conclusions: </strong>The on-table method has proven to be an effective treatment for comminuted fractures of the radial head with good functional outcomes. Considering the risks associated with radial head replacement, preservation surgery should be opted for if the nature of the fracture allows it.

It usually presents as a slow growing non-painful mass. The purpose of this study is to carry out a systematic literature review aimed to delineate the main clinical characteristics of this nosologically entity to define the therapeutic approach and outcome.</p><p><strong>Material and methods: </strong>A systematic literature review was conducted from March to June 2022 using five major databases: PubMed, Scopus, Embase, MEDLINE, and the Cochrane Library. Studies published in English between 1953 and 2022 reporting clinical cases of Calcifying Aponeurotic Fibroma (CAF) were considered. Eligible studies included case reports and case series; non-English articles, animal studies, and papers lacking sufficient clinical detail were excluded.

Administration of platelet-rich plasma (PRP) is one of the interventions that has been investigated for a long time. Professional medical societies have so far failed to adopt a clear and consistent stance on this therapy, despite a number of randomized clinical trials (RCTs) conducted in the past. The aim of our review was to evaluate the results of RCTs published over the last 5 years.

PubMed, OVID and Scopus databases were searched for the relevant data. The effect of PRP administration was evaluated using the total WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), VAS (Visual Analogue Scale) pain and IKDC (International Knee Documentation Committee) scores at time periods up to 6 weeks, at 3 and 6 months.

Depending on the initial assessment, the PRP treatment offers pain relief for up to 12 months after administration, together with a marked improvement in function of the affected knee. Even though the PRP is frequently administered in the clinical practice, it is not recommended by prestigious professional medical societies because of its relatively small effect and the absence of knowledge concerning the optimal patient responding reliably to this method.
