HUMERAL NAIL: COMPARISON OF THE ANTEGRADE AND RETROGRADE APPLICATION.

Application of humeral nail in the treatment of humeral shaft fractures is a relatively novel method of fracture fixation. Its application at Clinical Department of Traumatology, Sestre milosrdnice University Hospital Center began in 2001. The operative procedure should be performed using a minimally invasive technique without fracture opening in order to maintain optimal conditions for fracture healing including hematoma management.

Regional bone loss following femoral neck fracture: A comparison between cemented and cementless hemiarthroplasty.

The aim of this prospective, randomised study was to measure and evaluate regional bone mineral changes and clinical results following the use of cemented and cementless hemiarthroplasty (HA) for treatment of femoral neck fracture in elderly patients. The study comprised 60 patients, 30 with cemented HA (group A) and 30 with cementless HA (group B). All patients underwent osteodensitometry of the contralateral hip, lumbar spine and bilateral distal femur.

Minimally-invasive plate osteosynthesis in distal tibial fractures: Results and complications.

Introduction: Distal tibial or pilon fractures are usually the result of combined compressive and shear forces, and may result in instability of the metaphysis, with or without articular depression, and injury to the soft tissue. The complexity of injury, lack of muscle cover and poor vascularity make these fractures difficult to treat. Surgical treatment of distal tibial fractures includes several options: external fixation, IM nailing, ORIF and minimally-invasive plate osteosynthesis (MIPO).

Internal fixation of patellar apex fractures with the basket plate: 25 years of experience.

Introduction: Comminution of the patellar apex is amenable to internal fixation by standard techniques and usually requires partial patellectomy. In our institution, multifragmentary fractures of the distal pole are treated with the basket plate, which is shaped to fit the geometry of the patellar apex. This implant has been used in our institution for over 25 years.

New cementless fixation in hip arthroplasty: a radiostereometric analysis.

Introduction: Scyon Orthopaedics AG developed a new mode of cementless fixation of the femoral component that provides immediate and permanent anchorage by monocortical locking screws. The aim of this study was to evaluate the stability of the Scyon total hip replacement (THR) stem in-vivo.

Methods: A total of 15 patients, with an average age of 50 years had surgery between 2008 and 2011.

Reverse shoulder prosthesis: implementation and experience in Croatia.

Reverse shoulder prosthesis has become one of the most often used prosthetic implants in shoulder replacement surgery. It has a wide spectrum of indications, starting from comminuted humeral fractures and posttraumatic arthritis to arthritis caused by the rotator cuff loss. Its application at our hospital began in 2004, at first in few specific cases and with time in ever growing number of patients.

Periprosthetic bone loss following hemiarthroplasty: a comparison between cemented and cementless hip prosthesis.

The aim of this prospective randomized clinical study was to evaluate the magnitude of bone mineral changes as well as the clinical results after cemented and cementless haemiarthroplasty (HA) for femoral neck fracture. The study was comprised of 60 patients (mean age 85.2 years); 30 of them underwent cemented HA and 30 cementless HA.

Approach to distal femur by osteotomy of the patellar distal pole and internal fixation with basket plate in complex articular fracture: report of five cases.

According to AO classification, 33-C3 (complete articular multifragmentary) fracture of distal femur is characterized by complex articular involvement, along with short distal femoral block with multiple small fragments and usually with severe soft tissue abruption. In such cases of complex articular fracture of distal femur with extensive comminution of the femur condyle that is often seen in these fractures, anatomical reduction is quite difficult. Minimal fixation strategies sometimes do not provide an optimal degree of reduction and stability of the distal femoral block osteosynthesis.

Internal fixation with locking plate of 3- and 4-part proximal humeral fractures in elderly patients: complications and functional outcome.

Despite recent advances in operative techniques, internal fixation of (3- and 4-part) displaced proximal humeral fractures in elderly patients with osteoporotic bone remains controversial, sometimes followed by poor results. The aim of the present study was to evaluate outcomes of internal fixation with locking plate of multi-fragment proximal humeral fractures in elderly patients. The study cohort comprised 59 consecutive patients (mean age 70.

First report of connexin 43-positive gastrointestinal stromal tumor (GIST).

Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms most frequently found in the stomach and presenting without symptoms or with unspecific ones such as hemorrhage and abdominal pain. The malignant potential of GIST is variable and there are several prognostic indexes for treatment and follow up. The superior diagnostic method is endoscopic ultrasound combined with fine needle aspiration biopsy (EUS-FNA) immunocytochemistry.

Detecting Baker's cyst: venous duplex scanning in ambulatory setting.

Popliteal cyst, also called Baker's cyst, is a popliteal fossa enlargement filled with synovial fluid. Baker's cysts can be symptomatic and cause considerable pathologies such as thrombophlebitis, compartment syndrome and even nerve entrapment. It is the most common nonvascular pathology seen in the popliteal fossa but clinically indistinguishable from deep vein thrombosis.

Surgical treatment of pathologic fractures in patients with metastatic tumors.

The study presents results in treatment of pathologic fractures of long bones of all patients who underwent surgery in the last 10 years in our hospital. The study cohort comprised 133 consecutive patients divided in two groups who underwent surgery of long bone fractures caused by metastatic tumor or trauma. We used resection, open reduction and plating with bone cement application for pathologic fracture and some cases of femoral shaft fractures were stabilized with intramedullary nailing.

Analysis of muscle forces acting on fragments in pelvic fractures.

CT was used in 50 adult pelvic fractures to determine the size and the position of relevant muscles with regard to bony elements in order to calculate muscle forces acting upon certain pelvic portions. Muscle length was measured to calculate muscle volume and physiological muscle cross-section. Among others, the size and direction of muscle forces were calculated for iliac, pubic and ischiadic fractures.

Morphometry of the pelvic ring in definition of biomechanical factors influencing the type of pelvic fracture.

The aim of the study was to supplement data on pelvic morphology and structural geometry. Using these data, a mathematical and biomechanical model was constructed. The research was divided into two parts.

After 40 years gossypiboma caused spleen abscess.

We report a case of spleen abscess cased by foreign body (gossypiboma) after 40 years. After physical examination, laboratory, ultrasonography and CT findings with diagnosis of acute abdomen, 73 years old woman had undergone laparatomy. Operation revealed intraabdominal spleen abscess.

Botulinum toxin A injection for primary and recurrent chalazia.

Background: To study the efficacy and safety of subcutaneous botulinum toxin A injections in the treatment of primary and recurrent chalazia.

Methods: Prospective, placebo-controlled consecutive case-series trial. Sixty three patients were divided into two groups: group 1 consisting of 32 patients previously diagnosed with and treated for primary or recurrent chalazia with 2-5 international units (IU) in 0.

Biological value of melanoma inhibitory activity serum concentration in patients with primary skin melanoma.

Melanoma inhibitory activity (MIA) protein was identified in significant quantities in primary and metastatic malignant melanomas, where it has an important role in promoting tumor development and progression. Our hypothesis was that MIA serum level will be elevated in patients with metastases or local spreading of the disease before any symptom of such progression is clinically apparent. We compared MIA serum levels in two groups of patients with primary melanoma; those with positive as opposed to those with negative sentinel lymph nodes.

Multifragment fracture of the patellar apex: basket plate osteosynthesis compared with partial patellectomy.

Introduction: The purpose of the present study was to evaluate and compare the long-term results of operative treatment of a multifragment fracture of the inferior patellar pole by basket plate osteosynthesis and partial patellectomy.

Materials And Methods: We retrospectively studied two groups of patients who had operative treatment of a multifragment fracture of the inferior patellar pole between 1988 and 2004. Seventy-one patients who had osteosynthesis by basket plate (Group 1) and 49 patients who had partial patellectomy (Group 2) were followed for an average of 5.

Comparison of preoperative and postoperative astigmatism after superotemporal or superonasal clear corneal incision in phacoemulsification.

The aim of this work was comparison of preoperative and postoperative astigmatism after superotemporal or superonasal clear corneal incision. Twenty eight eyes of 28 patients treated with phacoemulsification through superotemporal or superonasal 3 mm clear corneal incision were examined by kerato-refractometer preoperatively and six months postoperatively. Adequate score was assigned to each preoperative and postoperative K-value with associated axis of astigmatism to enable comparison.

Basaloid squamous cell carcinoma of the esophagus: a case report.

Basaloid squamous cell carcinoma (BSCC) of the esophagus is an extremely rare tumor which should be differentiated from adenoid cystic and small cell undifferentiated carcinoma. We present the case of a 48-year-old male patient with esophageal BSCC. This tumor has specific histological features which may be difficult to recognize by small endoscopic biopsy examination.
