Primary Bone Lymphoma of the Scapula.

Primary bone lymphoma of the scapula is a rare tumor that usually causes local pain. The presented patient suffered for two years from paresthesia, tingling, numbness, and edema of the little and ring fingers. The 45-year-old man underwent several radiological and neurological assessments of the palm, elbow, and neck before radiographs revealed a tumor of the left shoulder.

HIP ARTHROSCOPY: RESIDUAL CAM DEFORMITY COMBINED WITH LOOSE BONY FRAGMENT IN HIP CAPSULE.

Hip arthroscopy is a minimally invasive, effective and innovative orthopedic procedure with a relatively low rate of complications. In our patient, residual cam deformity and a bone fragment that remained in the front hip capsule after hip arthroscopy performed three years before caused thigh numbness, muscle fasciculations, and paresthesia. It was assumed that the loose bony fragment remained following burring on prior procedure.

IMPACT OF CEMENTLESS ZWEYMÜLLER STEM ANTEVERSION ON RESISTANCE TO PERIPROSTHETIC FRACTURE IN TOTAL HIP ARTHROPLASTY.

Total hip arthroplasty implies proper orientation of both acetabular and femoral components with a range of 25-40° of combined anteversion. The aim of the study was to examine resistance to periprosthetic fracture of the axially loaded cross section rectangular femoral stem (Zweymüller) with respect to different degrees of anteversion, implanted in the artificial bone model, in laboratory conditions. Femoral bone models with implanted femoral stems were divided into 3 groups depending on the degree of stem anteversion (A, control group 13-17°; B, stem retroverted 0°-4°; and C, stem anteverted 26-30°).

Current knowledge on the genetic background of developmental dysplasia of the hip and the histomorphological status of the cartilage.

Developmental dysplasia of the hip (DDH) represents a morphological abnormality characterized by the incongruity of femoral head and acetabulum. It ranges from mild dysplastic changes to complete dislocation. DDH has been associated with several hereditary and environmental risk factors, which could explain the incidence variability among different countries.

Validation of revision data for total hip and knee replacements undertaken at a high volume orthopaedic centre against data held on the National Joint Registry.

Background: With over 2.35 million records, the National Joint Registry (NJR) is the largest arthroplasty registry in the world. It provides a powerful tool to monitor implant survivorship and influence different surgical strategies.

Sport injuries in international masters rowers: a cross-sectional study.

Aim: To estimate the frequency and localization of acute (traumatic) and chronic (overuse) injuries in a population of masters rowers with respect to their age subgroups and assess the association between injury occurrence and different training modalities, rowing experience, previous competition level, and current rowing practice.

Methods: A cross-sectional study was conducted among 743 masters rowers who participated in the 34th International Federation of Rowing Associations (Fédération Internationale des Sociétés d'Aviron, FISA) World Rowing Masters Regatta held in Zagreb, September 2-9, 2007. A rowing-specific questionnaire was used, followed by an interview about the injuries sustained during the 12-month period before the competition.

Ganglion Cyst of the Knee: A Retrospective Review of a Consecutive Case Series.

The aim of this study was to describe relevant medical history, clinical symptoms and outcomes in 12 patients having undergone surgical treatment of intra-articular ganglion cysts of the knee at our Department from January 2010 to June 2016. Patient demographics, medical history, knee manifestations, management and outcome were evaluated. The mean patient age was 26.

OSTEOID OSTEOMA OF THE CORACOID PROCESS: CASE REPORT WITH LITERATURE REVIEW.

Osteoid osteoma (OO) is the most common benign osteogenic bone tumor that predominantly affects young adults. OO is commonly localized in long bones, and therefore, it is rarely considered in differential diagnosis of chronic shoulder pain. We report a case of a 22-year-old male athlete, without history of previous trauma, who presented to our Department with chronic shoulder pain, which escalated during the night and responded to nonsteroidal anti-inflammatory drug treatment.

Patient survival and surgical re-intervention predictors for intracapsular hip fractures.

Background: Choosing between total hip replacement (THR) and partial hip replacement (PHR) for patients with intracapsular hip fractures is often based on subjective factors. Predicting the survival of these patients and risk of surgical re-intervention is essential to select the most adequate implant.

Methods: We conducted a retrospective cohort study on mortality of patients over 70 years with intracapsular hip fractures who were treated between January 2010 and December 2013, with either PHR or THR.

Localized pigmented villonodular synovitis of the ankle: Expect the unexpected.

Background: We present the technique, results and discuss arthroscopic treatment of the localized form of pigmented villonodular synovitis (LPVNS) of the ankle.

Methods: Medical records of five patients diagnosed and treated for ankle LPVNS with a minimum five-year followup were retrospectively reviewed. All patients were treated arthroscopically, altered synovial tissue was resected and a sample of tissue was sent for pathohistological examination for the definitive diagnosis.

Hamate hook nonunion initially mistaken for ulnar nerve compression: a case report with review of literature.

Background: Hamate hook (HH) stress fractures are rare, often presenting with misleading symptoms and easily overlooked/misdiagnosed. These fractures occur frequently in individuals participating in sports activities involving racquets, bats, or clubs. Symptoms are non-specific and often mimic other clinical conditions, such as ulnar nerve entrapment or ulnar vessel thrombosis.

Removal of Osteoid Osteoma of the Calcaneus Using Subtalar Arthroscopy.

Unlabelled: Intra-articular calcaneal osteoid osteoma is a very rare condition and the diagnosis as well as the treatment is extremely challenging. We report a case of a 19-year-old male with intra-articular osteoid osteoma of the calcaneus, initially treated for peroneal tenosynovitis with unsatisfactory results. Thorough diagnostic procedure revealed the superolateral location of a calcaneal osteoid osteoma, near the sinus tarsi.

[POSSIBILITIES AND LIMITATIONS OF SEXUAL ACTIVITY FOLLOWING TOTAL HIP REPLACEMENT].

Total hip replacement in patients with osteoarthritis significantly reduces pain and enhances the quality of life (QoL). Sexual activity is an important component of QoL about which doctors rarely discuss with patients even though it is a matter of concern to many patients. In fact, patients who have previously had impaired sexual function due to preoperative hip pain and/or stiffness find that after surgery their hips are pain free and have better motion.

Rowing Injuries: An Updated Review.

Although traditionally seen as a sport for elite schools and colleges, rowing is a founding Olympic event and is increasingly enjoyed by people of all ages and abilities. The sport's rapidly changing demographics shows significant growth in masters (age 27 years and above) and para-rowing populations. It has further expanded beyond its traditional flatwater format to include the discipline of open-water or coastal rowing, and an increased focus on indoor rowing.

IS THERE ANY ROOM FOR TENDOSCOPY IN THE SURGICAL TREATMENT OF POSTERIOR TIBIAL TENDON INSUFFICIENCY?

Posterior tibial tendon insufficiency (PTTI) is nowadays considered to be the main cause of adult-acquired flatfoot deformity (AAFD). The purpose of this study is to report the outcomes of tendoscopic treatment of tibialis poste- rior tendon (TP) in eleven patients with stage 1 or 2 PTTI and failed prior conservative treatment. Tendoscopy was carried out as a solitary procedure in 8 patients, while in 3 patients additional procedures such as ,,mini-open" tubularization of TP or anterior ankle arthroscopy were necessary.

Clinical and MRI Outcomes After Surgical Treatment of Osteochondral Lesions of the Talus in Skeletally Immature Children.

Background: The literature on the osteochondral lesion of the talus (OLT) in skeletally immature children is scarce and little is known about the clinical outcomes and the radiologic appearance of these lesions after surgical treatment. The aim of this study was to assess mid-term clinical and magnetic resonance imaging (MRI) outcomes after arthroscopic microfracture (AM) of OLT in skeletally immature children.

Methods: Thirteen patients with OLT treated by AM before skeletal maturity were included in the study.

[Posterior ankle impingement syndrome].

Posterior ankle impingement syndrome (PAIS) is a clinical syndrome characterized by posterior ankle pain which occurs in maximal forced plantar flexion of the foot. PAIS can be the result of an acute injury of the ankle, which is more often in general population, or it can be the result of the overuse syndrome, which is more often in athletes and ballet dancers. The etiology of PAIS may involve bony structures or soft tissue structures, or, more often, the combination of both.

Peroneal tendoscopy--more than just a solitary procedure: case-series.

This study presents a series of 13 patients who underwent peroneal tendoscopy as a solitary or accessory procedure at our department in 2013. Patients were clinically diagnosed with peroneal tendons disorders and underwent an additional radiological assessment. Peroneal tendoscopy was carried out in a standard manner before any other arthroscopic or open procedure.

[Peroneal tendons do exist, don't they?].

Peroneal tendon disorders are a significant but often overlooked cause of posterolateral ankle and lateral foot pain. When left untreated, peroneal tendon disorders can lead to persistent pain and substantial functional problems. The goals of this review are to develop a current understanding of the regional anatomy, as well as diagnostic evaluation and current treatment options of the peroneal tendon disorders, and to present nowadays preferred surgical techniques for operative management of peroneal tendon disorders.

Acute and chronic injuries among senior international rowers: a cross-sectional study.
