The aim of this study was to describe a surgical technique and report on patient-based functional outcomes and complications following open reduction and internal fixation in patients with scapular ...fractures.
The study comprised 14 patients who were treated with open reduction and internal fixation (ORIF) of a scapular fractures between September 2010 and July 2018. Surgical indications were as follows: medial/lateral displacement greater than 20 mm; shortening greater than 25 mm; angular deformity greater than 40°; intra-articular step-off greater than 4 mm; and double shoulder suspensory injuries (including fracture of the clavicle, coracoid or acromion with displacement greater than 10 mm). All patients underwent X-ray examination (true AP, Y scapular view) and computed tomography (CT) scans. Fractures were classified according to the revised (AO/OTA) classification system. Functional outcomes were measured using Constant-Murley scores.
Seven patients had glenoid fossa fractures, six patients had scapular body fractures and one patient had an acromion process fracture. All glenoid fossa and scapular body fractures were exposed via the Judet approach. Eleven of 14 patients were given Constant-Murley scores at the final follow-up examination; three patients were lost to follow-up. The mean follow-up after injury was 44 months (range, 6–92 months). We found infraspinatus muscle hypotrophy in four patients. The mean Constant-Murley score was 93.45 (±8.93) for the injured arm and 98.36 (±2.91) for the uninjured arm. The mean score between the injured and uninjured arm was 4.91(±6.49), which is an excellent functional outcome according to the Constant-Murley score.
Open reduction and internal fixation of displaced scapular fractures is a safe and effective treatment option that results in a reliable union rate and good-to-excellent functional outcome.

High-energy trauma of the lower leg can cause conditions such as bone defects, loss of the articular surface or a complex soft tissue injury. Given the type of the injury, as well as the often poor ...general status of the patient, the initial treatment usually consists of debridement and external fixation. The role of the retrograde calcaneo-talo-tibial nail is acknowledged in the treatment of post-traumatic arthritis of the talocrural joint, rheumatic arthritis, the neuropathic joint as well as some other conditions. We present a case of a thirty-five-year-old man with a lower leg fracture and significant bone defect associated with the loss of the articular surface of the distal tibia which was treated with a retrograde calcaneo-talo-tibial nail. Due to the lack of an adequate implant on the market, an inversely introduced tibial nail was used. Following the nailing of the fracture and the recovery of the soft tissue, transposition of the ipsilateral fibula was performed. Nowadays, different methods for bone defect reconstruction are available such as distraction osteogenesis, bone transport, and the Masquelet technique. However, the calcaneo-talo-tibial nail and transposition of the fibula is another feasible and effective option, especially for unreconstructable joint surfaces.

The aim of this study was to compare union time between two different nail designs for the treatment of humeral shaft fracture, i.e. antegrade interlocking intramedullary nail with and without ...additional interlocking neutralization screws. The retrospective study included 51 patients treated with antegrade humeral intramedullary nailing between January 2015 and December 2017. The inclusion criteria of the study were proximal and middle third humeral shaft fractures. Fifty-one patients met the inclusion criteria; 23 patients were treated with antegrade intramedullary nail with additional interlocking neutralization screws through fracture site (group A) and 28 patients were treated with antegrade intramedullary nail without additional interlocking neutralization screws (group B). Medical documentation and radiographic images taken preoperatively and postoperatively were reviewed. Radiological union was defined as cortical bridging of at least three of four cortices in two-plane radiographs, with disappearance of the fracture gap. There were no significant differences in union time between the groups (p>0.05). To our knowledge, this is the first report of antegrade interlocking humeral nailing with additional interlocking neutralization screws through fracture site. Hypothetical advantages of fracture gap reduction by additional interlocking neutralization screws to promote union were not confirmed by this first clinical trial.
Bone tissue banks are necessary for collection, production, testing, packaging, storage and delivery of bone transplants. Bone tissue bank is a link between the donor and the recipient by which the ...donation becomes a medium of health improvement for both the donor and the recipient. At the Department of Orthopedics, Mostar University Clinical Hospital, about 200 total hip replacements are performed
per
year. Most patients undergoing total hip replacement surgery (90%) have been diagnosed with osteoarthritis, and they are suitable donors, having in mind their age and comorbidities. In the same Department, around 50 procedures that require bone transplants are performed
per
year. A team of highly competent surgeons are working on an intensive process of adaptation oriented to quality improvement and intensification of the activity, both with the goal of meeting the standards of excellence in orthopedic surgery. The presence of a bone tissue bank has a favorable impact on the quality of health care owing to bone transplant availability, as well as on the scientific role of a highly specialized institution that examines the properties of bone tissue.
This study investigates the mechanical behavior of femur bones under loading conditions, focusing on the transition from elastic to plastic deformation and eventual fracture. The force–displacement ...curves reveal distinct phases of deformation, with an initial linear relationship indicating elastic behavior, followed by deviation from linearity marking the onset of plastic deformation. Fracture occurs beyond a critical load, leading to a sharp drop in the force–displacement curve. The maximum fracture force varies among specimens and is influenced by bone geometry, size, cross-sectional area, and cortical thickness. Post-failure analysis highlights additional insights into fracture mechanics and bone material toughness. Reinforcing bones with screws enhances their strength, which is evident in the higher fracture forces observed in force–displacement diagrams. Fixation procedures following fractures further increase bone strength. Comparing specimens with and without strengthening underscores the effectiveness of reinforcement methods in improving bone mechanical properties. After analyzing the results, it is evident that femur bones with reinforcement can withstand greater loads, and they can also absorb higher impact energies while remaining in the elastic deformation range and without suffering permanent plastic damage. This study provides valuable insights into bone biomechanics and the efficacy of reinforcement techniques in enhancing bone strength and fracture resistance.
Previous studies have shown substantial effect thermal damage can have on new bone formation following osteotomy. In this study we evaluated the extent of thermal damage which occurs in four ...different methods of osteotomy and the effects it can have on bone healing. We further wanted to test whether a special osteotomy plate we constructed can lead to diminished heat generation during osteotomy and enhanced bone healing. The four methods evaluated included osteotomy performed by chisel, a newly constructed osteotomy plate, Gigly and oscillating saw. Twelve adult sheep underwent osteotomy performed on both tibiae. Bone fragments were stabilized using a fixation plate. Callus size was assessed using standard radiographs. Densitometry and histological evaluation were performed at 8 weeks following osteotomy. Temperature measurements were performed both in vivo during the operation, and ex vivo on explanted tibiae. The defects healed without complications and showed typical course of secondary fracture healing with callus ingrowth into the osteotomy gap. Radiographic examination of bone healing showed a tendency towards more callus formation in bones osteotomized using Gigly and oscillating saw, but this difference lacked significance. Use of Gigly and oscillating saw elicited much higher temperatures at the bone cortex surface, which subsequently lead to slightly impaired bone healing according to histological analysis. BMD was equal among all bones. In conclusion, the time required for complete healing of the defect differed depended greatly on the instruments used. The newly constructed osteotomy plate showed best results based on histological findings of capillary and osteoblast density.
The epidemic of cholera that took place in the Neretva basin in 1886 was part of the fifth pandemic wave that was spreading throughout Europe. Based on the death records, vital statistics and the ...newspaper articles from that period, in this paper we present the emergence and the course this epidemic. In the context of analysis and experience of the epidemic of cholera in the lower Neretva basin, the newspaper articles have been recognized as a sensitive register of the changes of behavioural patterns, the way of speaking, the mechanisms of reacting and adjusting to the spreading epidemic, but also the resistance to it. It is based on this material that we can make conclusions about the relationship between the individual and the collective in the time of danger, as well as about the particularities of historical events that have been left out in other sources. Two potential paths for cholera to enter the area of the lower Neretva basin have been identified: one from the sea and the other from land, via the neighbouring country of Bosnia and Herzegovina. Quarantine measures had been taken in order to prevent the onslaught of the epidemic, a sanitary cordon was organized, disinfection of the land was carried out and a cholera hospital organized in Metković. However, despite the undertaken measures, an inefficiency of the government organs was obvious, because their actions mainly applied to formal fulfilment of anti-epidemic measures and they quite easily handed over individual initiatives to physicians. The analysis of strategies concerning the application of anti-epidemic measures in the past can be useful for learning more about the multilayered nature of social mechanisms in the time of epidemics, which makes it convincing and valuable even in the present day.
Pituitary tumors are rare tumors (less then 10%) of the central nervous system (CNS), which malignicity depends on their localization, meanwhile, their biological nature is benign. The diameter they ...have is mostly less then 10 mm (microadenomas), but sometimes could be 10 mm (macroadenomas) to 5 cm and more and then are usually nonfunctional (about 20% of all pituitary tumors). Clinical presence depends on their localisation and hormonal activity. In the Center for Clinical Neuroendocrinology and Pituitary Diseases, in the last working 10 years, there were treated and examined 504 patients from Croatia, all with pituitary tumors: 182 patients with prolactinomas, 137 with acromegaly, 70 with Morbus Cushing (Mb. Cushing), and 115 patients with nonfunctional pituitary tumors. The patient's classification is based on regional (Mediterranean and continental region, 20 counties) and the state level. In our analysis we haven't found difference in incidence of tumors between Mediterranean and continental region.
Porast zdravstvenog standarda u smislu kvalitetnije i učinkovitije zdravstvene skrbi rezultira porastom očekivane životne dobi. U populaciji dolazi do porasta broja starijih osoba. S jedne strane ...povećana aktivnost starije populacije dovodi do veće incidencije ozlijeđivanja, a s druge strane raste broj komorbiditeta kod takve populacije. Poremećaji cirkulacije, dijabetes melitus, metabolički disbalansi i dr. te smanjeni biološki potencijal regeneracije tkiva ima za posljedicu povećanje broja pacijenata s
kroničnim ranama. One su značajan zdravstveno-sociološki i ekonomski problem za društvo. Zahtijevaju značajni angažman medicinskog i nemedicinskog osoblja u prethospitalnim i hospitalnim uvjetima, a značajni materijalni i nematerijalni resursi odvajaju se iz zdravstvene skrbi. Sve to rezultira smanjenom kvalitetom života bolesnika i njegove obitelji, odnosno skrbnika. Debridement je krucijalni medicinski postupak u liječenju akutnih i kroničnih rana. Rezultat debridmana je uklanjanje svih zapreka u rani i neposrednoj okolini rane, a koje opstruiraju odvijanje fi zioloških procesa u cijeljenju rane. Debridement se ponavlja prilikom svakog previjanja rane kada ima indikacija za njegovu primjenu. Postoji više vrsta debridmana. Svaki ima svoje prednosti i nedostatke. Metodu debridmana određuje liječnik ili druga stručna educirana osoba na osnovi karakteristika rane i u skladu sa svojom stručnosti i mogućnostima. U istoj rani mogu se kombinirati razne vrste debridmana, a sve sa ciljem što bržeg i kvalitetnijeg cijeljenja rane.
The aim of this study was to compare reduction quality and functional outcome of posterior malleolus fractures treated with indirect reduction and anteroposterior (AP) fixation or with direct ...reduction via a posterolateral approach and posteroanterior (PA) fixation.
Forty-eight patients with trimalleolar fracture were enrolled in the study. Patients were randomised in two groups: indirect reduction and AP fixation (AP group) and direct reduction and PA fixation (PA group). Inclusion criteria were: posterior fragment involving more than 25% of the articular surface, displacement over 2mm and ankle instability. The quality of reduction was evaluated using postoperative plain radiographs. Residual displacement of the posterior fragment, articular step-off and/or articular surface gap were analysed. The reduction was considered excellent (<1mm), good (1–2mm) or poor (>2mm). Range of motion (ROM) was measured bilaterally, and the difference in dorsiflexion between the injured and uninjured side was considered as dorsiflexion restriction. Demographic data (age, sex), type of fracture (AO/ASIF classification) and complications were noted.
Forty-six patients completed all follow-up examinations. There was no statistically significant difference in age (p = 0.41), sex (p = 0.29) or specific type of fracture (p = 0.83) distribution between the AP and PA groups. All fractures completely healed within 3 months. The overall complication rate was 8.7%. There was no statistically significant difference in complication rate between the two groups (p = 0.71). Radiological evaluation of the ankle showed there was significantly better quality of reduction with direct reduction via a posterolateral approach in the PA group. Excellent reduction was achieved in 79.2% and 45.5% of the PA and AP groups, respectively. The quality of reduction was significantly higher in the PA group compared with the AP group (p = 0.04). The mean restriction of dorsiflexion was lower in the PA group (5.96 ± 0.65°) compared with the AP group (6.45 ± 1.06°), but this difference did not reach statistical significance (p = 0.07).
The direct reduction technique via a posterolateral approach and PA fixation enables higher quality of reduction and better functional outcome in the management of the posterior fragment compared with indirect reduction and percutaneous AP fixation.
