Background: Intraoperative radiograph of the pelvis is a well-established way to avoid misplacement/undersizing of the components and leg length discrepancy (LLD) in total hip replacement (THR). We describe a method for the obtainment and the evaluation of intraoperative radiographs with a sophisticated wireless radiographic system and a computerized digital tool originally used for preoperative templating.

Methods: In this retrospective case-control study, 60 patients with unilateral hip osteoarthritis who underwent THR with intraoperative radiographic check with the conventional method (n = 30, control group) or the new method (AGFA flat panel DR14eG™/Orthosize™, n = 30, case group) were evaluated and compared for operation time, intraoperative changes in size/placement of the components and final radiological outcome (LLD, acetabular inclination and femoral offset) based on postoperative radiographs of the pelvis.

Isolated scaphoid dislocations are extremely rare injuries and are commonly associated with significant ligamentous disruptions. A dorsiflexion-supination force upon the hand is considered as the most common mechanism of injury. Different treatment options have been proposed for the management of this uncommon entity, ranging from conservative treatment with closed reduction and casting to a wide range of open or percutaneous surgical techniques.

Introduction: Hypersensitivity to implants is a rare complication of total knee arthroplasty (TKA). Metal and, less frequently, bone cement can produce allergic symptomatology that if unresponsive to conservative treatment could lead to revision.

Materials And Methods: We present the case of a patient with generalized pruritus and metal taste starting during the first postoperative month after TKA.

Introduction: Dislocation/subluxation of the Extensor Carpi Ulnaris (ECU) tendon is a rare condition in the general population, but is a common problem among athletes that subject their wrists to forceful rotational movements. Pain and snapping sensation at the dorsoulnar aspect of the wrist especially during supination are the predominant symptoms that often necessitate surgical intervention.

Case Presentation: We present a case of a professional water-polo athlete with recurrent ECU tendon dislocation, in whom a combination of direct repair of the tendon's subsheath and reinforcement with an extensor retinaculum graft led to definitive resolution of her symptoms and resulted in her uneventful return to high-level sport activities 4 months postoperatively.

Background: Neglected knee dislocations are extremely uncommon and their management cannot be evidence-based since only a few case reports have been published describing different treatment methods. We present the case of a young man with a neglected posterolateral knee dislocation and a concomitant sciatic nerve injury.

Methods: A two-stage treatment strategy with gradual reduction using the Ilizarov technique and subsequent arthroscopic anterior and posterior cruciate ligament reconstruction was followed.

Butterfly vertebra is a rare congenital malformation of the spine, which is usually reported in the literature as an isolated finding. We describe a 40-year-old woman that presented to our emergency department with back pain and sciatica. Initial radiological evaluation revealed an incidental finding of a L4 butterfly vertebra in the anteroposterior and lateral view radiographs.

We present the outcome of 241 consecutive low friction arthroplasties (LFAs) performed by one surgeon (GH) 30 to 40 years ago. The overall survival rate at 30 years with revision for any reason or removal of the components as the end point was 53% (43.2-62.

Management of posttraumatic segmental bone loss as a result of severe open injuries of the lower extremity, high-energy closed injuries, and following failed initial treatment of complex fractures that develop pseudarthrosis continues to challenge reconstructive surgeons. There are numerous strategies for dealing with such injuries but the outcome is unpredictable. The procedure is rarely only one stage and complications frequently arise.

To address the need to impact the subchondral bone-articular cartilage interaction for the treatment of degenerative osteoarthritis (OA), bisphosphonates may be used as a means to inhibit the subchondral bone resorption. The purpose of the present study is to evaluate the chondroprotective effect of zoledronic acid (ZOL) in a model of OA. Eighteen adult male rabbits underwent an anterior cruciate ligament transection and were separated into two groups: ZOL group (n=10) received 0.

The purpose of the present study was to evaluate the long-term outcome of the unrevised part in one-component total hip arthroplasty revision (index operation). Forty-four patients (46 hips) with a mean age of 58years at the time of the index operation were included. At the final follow-up, 4 of the 19 (21%) unrevised acetabular components and 6 of the 27 (22%) unrevised femoral components were subsequently revised at a mean time of 14 and 11years from the index operation, and 22 and 24years from the primary operation, respectively.

Objective: Despite the existence of numerous case series, no evidenced-based medical management for atypical fractures associated with bisphosphonate (BP) treatment has been established.

Design: We report the outcome of teriparatide (TRP) administration followed by strontium ranelate (SR) in a woman with a complete and an incomplete contralateral atypical fracture of the femoral diaphysis (AFF) associated with BP treatment. The spontaneous complete AFF was managed with intramedullary nailing, discontinuation of BP and initiation TRP.

Objective: Pregnancy- and lactation-associated osteoporosis (PLO) is an uncommon disease. The majority of cases are seen in the third trimester or early post-partum in primagravid women and the prominent clinical feature of PLO is severe and prolonged back pain and height loss. The prevalence and aetiology of this disorder are as yet unclear and there are no guidelines for its treatment.

Hajdu-Cheney syndrome (HCS) is a rare genetic disorder characterised by acro-osteolysis, skull deformation and generalised osteoporosis. Recently, truncating mutations in the last exon of NOTCH2, a protein-coding gene, were found to be responsible. We present the case of a young woman with HCS in whom clinical and radiologic diagnosis was confirmed with DNA tests.

Anterior or anterior-lateral dislocation of the ankle is a rare condition that can be treated conservatively as well as any other similar types of ankle dislocations without associated fractures. We present a case report of an anterior-lateral ankle dislocation with a concomitant avulsion injury of the ankle's anterior capsule in a diabetic patient that was treated conservatively. At the patient's visit 12 months after the initial injury, he was asymptomatic with full range of motion of the ankle joint.

Objective: The unique pharmacokinetics of bisphosphonates (BPs) in conjunction with their use by an increasing number of women at reproductive age has raised serious concerns about their safety during pregnancy and lactation. Bisphosphonates cross the placenta. Animal studies have shown adverse effects on both the fetus and the mother, mostly at doses much higher than those commonly used in humans.
