Isolated acetabular revision with femoral stem retention using computed tomography-based navigation

DiscussionUsing the navigation system, combined anteversion is made near the target angle in isolated acetabular revision surgery and more accurately than manual implantation. These results should be considered as preliminary since this is a limited cohort, but it brings new knowledge in navigation considering the very limited number of series using of navigation in isolated cup revision of total hip arthroplasty. In addition this is the first study to investigate combined cup and stem anteversion in isolated acetabular revision. The use of CT-scan is helpful to diagnose error in stem anteversion and to adapt the orientation of the new cup.Level of evidenceIII, Retrospective case control study.

ConclusionThese formulas are suggested to be used to calculate residual size of bone lesion after cystostomy and cystectomy to predict postoperative bone healing.Clinical relevanceThe formulas are based on deliberately simple measurement using only panoramic radiographs to encourage their application in daily clinical practice.

Imaging with biomechanical analysis augments the clinical examination and improves outcomes by correlating imaging findings with the examination. Plain film radiographs are the gold standard to assess osseous alignment. The biomechanical examination provides information to formulate an accurate assessment. Weightbearing computed tomography scanning is a potentially valuable for functional information about joint biomechanics. True alignment of the lower extremity can be appreciated on weightbearing computed tomography scanning. Soft tissue structures can be assessed with diagnostic ultrasound examination. Acute and chronic...

Objective: To compare the rate of malreduction after high fibular fractures associated with syndesmosis injury treated with open reduction and internal fixation, with either 2 screws or 1 knotless TightRope device. Design: Prospective randomized controlled multicenter trial. Setting: Eleven academic and community hospitals including Level 1 and Level 2 trauma centers across Canada. Patients/Participants: One hundred three patients with OTA/AO 44-C injuries with demonstrated radiographic syndesmosis diastasis or instability after malleolar bony fixation were followed for 12 months after treatment. Methods: Ope...

We present images of 177Lu-DOTATATE scan and 68Ga-DOTATATE PET/CT scan conducted on a 65-year-old man with prostate cancer with neuroendocrine differentiation, whose disease progressed despite conventional treatment and 177Lu-PSMA radioligand therapy; however, an extraordinary radiographic tumor remission, biochemical response, and improvement of clinical symptoms were observed after the patient underwent 177Lu-DOTATATE peptide receptor radionuclide therapy.

This study was aimed to estimate the length of the MIC in the interforaminal safe zone, to analyse its course in relation to the lingual and the buccal cortical plates of the mandible using cone beam computed tomography (CBCT) scans and to relate the above findings to age, gender, dental status and Malaysian races.MethodsRetrospective analysis of 100 CBCT scans (n = 200) was performed on both sides of the mandible. Cross-sectional and panoramic images were reconstructed. The length of the MIC and the horizontal distances between the MIC and the buccal and the lingual cortical plates were measured at the three...

ConclusionsThe carotid bifurcation is in close proximity to various calcified anatomical structures. This should be taken into account when diagnosing CCPs in panoramic radiographs (PRs). In the coronal view, CCPs and the cervical spine are often superimposed; thus, coronal images are not recommended for confirmation of putative carotid calcifications diagnosed on PRs.

Conclusions: The Schneiderian membrane thickness was positively and highly associated with gingival biotype. The gingival biotype and arch form had significant effect on Schneiderian membrane thickness and can provide valuable clinical information on Schneiderian membrane thickness preoperatively for implant placement and sinus lift procedures.

This study found that The Canary System was more accurate than Bitewing Radiographs and Cone Beam CT in detecting caries on the gingival floor beneath composite restorations.  The sensitivity and specificity data (table on the right) indicates that The Canary System could find 89% of the caries where the other devices found 40% of the lesions.One of the major reasons for replacing restorations is tooth decay that develops around the edges of the filling.  This study found that “Radiographs though valuable in the detection of advanced caries lesions, are less sensitive for early or recurrent lesions under re...

This study compares the long-term functional, radiographic, and computed tomography (CT) scan outcomes and implant survivorship of ceramic-on-ceramic total hip arthroplasty (C-O-C THA) and ceramic-on-highly X-linked polyethylene total hip arthroplasty (C-O-HXLPE THA) in the same patients.

Discussion Foreign bodies are common problems for young children particularly ages 2-4 years who will mouth many objects and aspirate or swallow them. Children will also place foreign objects in other body orifices such as ears or noses. It is also not uncommon that young girls will inadvertently have toilet paper caught in the vaginal area during hygiene. Many of these foreign bodies may work their way out naturally not causing any problems, or may come to attention later because of chronic problems such as a foul-smell or discharge. Older children may tell adults that they have placed a foreign body in an orifice and thu...
