Wide resection for giant-cell tumor of the distal radius: which reconstruction? A systematic review of the literature and pooled analysis of 176 cases.

Giant-cell tumor (GCT) is often more aggressive when located in the distal radius, and wide resection is then the gold-standard. No single reconstruction protocol is recommended, and the technique depends upon the surgeon's preferences. The aim of the present review was to determine the recurrence rate of GTC of the distal radius after intralesional treatment, to assess the results, advantages and complications of the various surgical techniques, and to draw up a decision-tree for surgical indications. The review of literature was performed in the main healthcare databases, searching for studies that reported results of wide resection and reconstruction of distal radius GCT. Local recurrence rates, metastasis rates, reconstruction techniques and respective results and complications were evaluated and analyzed. Sixteen studies were selected, for a total population of 226 patients; 6.0% and 0.9% experienced local recurrence and lung metastasis, respectively. Arthroplasty with non-vascularized or vascularized ipsilateral fibula were the most common techniques and were associated with the highest satisfaction rates: 86.4% and 88.0%, respectively. Arthroplasty with allograft presented a MusculoSkeletal Tumor Society (MSTS) score of 79.2% and arthroplasty with custom-made prosthesis presented an MSTS score of 81.8%. Arthrodesis was performed in 46 cases, with an MSTS score of 82.7%. Arthroplasty techniques are the most common in literature; they are used in patients who wish to conserve joint motion. Reconstruction with non-vascularized fibula seems to provide the best results, with lower morbidity. Arthrodesis is usually reserved for heavy manual workers or in case of arthroplasty failure.

Percutaneous puncture during PCNL: new perspective for the future with virtual imaging guidance.

CONTEXT: Large and complex renal stones are usually treated with percutaneous nephrolithotomy (PCNL). One of the crucial steps in this procedure is the access to the collecting system with the percutaneous puncture and this maneuver leads to a risk of vascular and neighboring organs' injury. In the last years, the application of virtual image-guided surgery has gained wide diffusion even in this specific field. OBJECTIVES: To provide a short overview of the most recent evidence on current applications of virtual imaging guidance for PCNL. EVIDENCE ACQUISITION: A non-systematic review of the literature was performed. Medline, PubMed, the Cochrane Database and Embase were screened for studies regarding the use virtual imaging guidance for PCNL. EVIDENCE SYNTHESIS: 3D virtual navigation technology for PCNL was first used in urology with the purpose of surgical training and surgical planning; subsequently, the field of surgical navigation with different modalities (from cognitive to augmented reality or mixed reality) had been explored. Finally, anecdotal preliminary experiences explored the potential application of artificial intelligence guidance for percutaneous puncture. CONCLUSION: Nowadays, many experiences proved the potential benefit of virtual guidance for surgical simulation and training. Focusing on surgery, this tool revealed to be useful both for surgical planning, allowed to achieve a better surgical performance, and for surgical navigation by using augmented reality and mixed reality systems aimed to assist the surgeon in real time during the intervention.
