Recurrent Adamantinoma With Fibrous Dysplasia-like Feature.

Adamantinoma (AD) is a rare, slow-growing primary malignant bone tumor characterized by a biphasic morphology of clusters of epithelial cells and spindle cell osteofibrous components. A strong relationship between AD and osteofibrous dysplasia (OFD) has been proposed, while fibrous dysplasia (FD) has been rarely associated with AD. We present an AD case that was followed and histologically evaluated 3 times over 6 years with different morphological patterns.

Serum Levels of Inflammatory and Fibrotic Cytokines in Patients with Carpal Tunnel Syndrome and Hip Osteoarthritis.

A certain percentage of carpal tunnel syndrome (CTS) is associated with inflammatory conditions. Osteoarthritis (OA) increases the risk of CTS, and both diseases are common in the general population. Moreover, OA and CTS are often present in the same patients.

Functional recovery after muscle sparing total hip arthroplasty in comparison to classic lateral approach - A three years follow-up study.

Background: The muscle sparing total hip arthroplasty had generated a distinguishable interest, in both the patients and the surgeons, but its benefits are still often questioned. The main idea of this study was to compare the functional clinical outcome of the patients operated by the anterolateral approach with a muscle-sparing technique (modified Watson-Jones approach), and the patients operated by modified direct lateral approach without the muscle-sparing technique (Bauer/Hardinge approach).

Methods: The patients (N = 130) were divided into two groups: 68 in a standard method group (STAND) and 62 patients in a muscle sparing surgery group (MSS).

Expression of the BMP-2, -4 and -7 and their antagonists gremlin, chordin, noggin and follistatin during ectopic osteogenesis.

Molecular network of the osteogenic BMPs and extracellular inhibitors maintains homeostasis of the skeletal tissues. It is important to determine relationship between BMP-2, -4 and -7 and their inhibitors: gremlin, follistatin, chordin and noggin, during normal osteogenesis. To determine their expression pattern we conducted investigation by inducing ectopic bone formation in rats.

The "cello technique": a new technique for ultrasound-assisted calcaneoplasty.

The "cello technique" is a new calcaneoplasty technique for the treatment of Haglund disease. It is an ultrasound-assisted technique for resection of the posterosuperior part of the calcaneus. It is possible to resect the posterosuperior part of the calcaneus under direct ultrasound control with the patient in the prone position, with a dorsally positioned ultrasound probe, in line with the Achilles tendon fibers (sagittal line), and with the abrader in the posteromedial working portal.

Measuring improvement following total hip and knee arthroplasty using the SF-36 Health Survey.

The aim of this study was to evaluate the impact of total hip or knee arthroplasty upon quality of life in elderly patients. The study was carried out at the Clinic for Orthopaedic Surgery Lovran on 74 total hip arthroplasty and 70 total knee arthroplasty patients. All patients had completed the Medical Outcomes Study 36-Item Short Form in the week having preceded their surgery and then again postoperatively, 2 years after.

New "L value" parameter simplifies and enhances hip ultrasound interpretation in the detection of developmental dysplasia of the hip.

Purpose: The purpose of this study was to simplify and enhance the ultrasound (US) analysis of the infant's hip by introducing a novel parameter named "L value" into the widely used Graf method.

Methods: We analysed 508 ultrasonographic images of the hips in infants aged three months. The images were first evaluated using the Graf measurements.

Giant pseudocyst of the rectus femoris muscle--repetitive strain injury in recreational soccer player.

We report a case of a traumatic pseudocyst, in a recreational soccer player, after rupture of rectus femoris muscle. 37-year-old male, with history of repetitive painful accidents, was examined because of a double fist-sized mass in the anterior thigh. Ultrasound examination revealed a cystic mass in the rectus femoris muscle.

Postoperative blood loss management in total knee arthroplasty: a comparison of four different methods.

Purpose: As the blood loss after the total knee arthroplasty (TKA) is not only a potentially serious medical problem but also an economical concern, the purpose of the study was to investigate the effectiveness of different combinations of knee positioning and the applied wound dressings on blood saving after TKA.

Methods: A randomized controlled trial including 147 TKA-operated patients was conducted. The subjects were assigned to one of the four groups; Group 1-controls, Group 2-flexion, Group 3-flexion and compression, Group 4-compression.

Bone allograft provides bone healing in the medial opening high tibial osteotomy.

Various materials are used to fill osteotomy defects created in the medial opening wedge high tibial osteotomy (MOWHTO). Our hypothesis was that a bone allograft would provide the osteotomy site bone healing within the expected time. We performed the MOWHTO using a cancellous bone allograft in 310 knees in 284 patients between 2000 and 2005.

Keller's arthroplasty with proximal metatarsal opening wedge osteotomy in treating severe Hallux valgus deformity--surgical techniques and case report.

The paper presents an operative technique proposed for treating severe Hallux Valgus deformity with arthrosis of the first metatarsal joint in elderly people. The procedure consists of the Keller's arthroplasty in combination with basal osteotomy of the first metatarsal bone, whereby the head of the metatarsal is displaced laterally and plantarward. The osteotomy is fixed with a reconstructive plate.

Arthroscopic removal of metal foreign bodies from the knee joint after explosive war injuries.

The results of arthroscopic removal of metallic fragments from knee joint due to explosive war injuries are presented. In period from 1991-1995 during war in Croatia we have operated 25 knee joints. Indications for arthroscopy were based on radiographic and clinical findings.

Microfracture technique in combination with intraarticular hyaluronic acid injection in articular cartilage defect regeneration in rabbit model.

Although articular hyaline cartilage typically has low potential for regeneration, numerous methods and techniques have been proposed to induce the reparation process. In our work, we used microfracture techniques in combination with intraarticular application of hyaluronic acid in rabbit knee articular cartilage defect. In comparison with the control group, after 6 and 10 weeks we observed a higher potential of healing in the experimental group, with thicker and more organized repair tissue filling the defect.

Limb salvage surgery in Enneking's stage III a--a case of leiomyosarcoma.

Limb saving surgery is today's tendency in treating the musculoskeletal tumours. Preserving the limb should not only pursue a good oncological and functional result but also aim at good psychological outcome. Our aim was to treat a very rare case of proximal femoral leiomyosarcoma with present solitary lung metastasis by conservative operative procedures.

Treatment of tibial bone defect with rotational vascular periosteal graft in rabbits.

It is well known that the periosteum is capable of bone formation. In the present study, the value of the vascularized periosteal graft in healing the long-bone defect filled with the allogenous bone graft was studied. The aim of the study was to verify the efficiency of the rotational vascularized periosteal graft as a optional surgical method as well as to prove its advantages in comparison with the nonvascularized periosteal graft.

[Bone bank at University Department of Orthopedic Surgery in Lovran, Croatia].

Aim: At University Department of Orthopedic Surgery in Lovran, bone bank was established in 1985 for preserving and storage of musculoskeletal tissue. At first, storage was only done for femoral heads as surgical residues of hip replacement. Since 1993, storage is also done for transplants obtained by retrieving bone allografts from cadavers during multiorgan explantations.
