ABSTRACT

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.

ABSTRACT

INTRODUCTION: Core biopsy is today recognized as the gold standard for the diagnosis of bone lesions; unfortunately, when the bone is too solid it can be very difficult to penetrate it; in case of failure, open biopsy is indicated but it is associated with greater contamination and complications. A possible solution is to connect a common orthopedic drill to the core biopsy needle. The aim of the presenting study was to present a technique useful for performing biopsies in case of very strong bone lesions and to evaluate the adequacy and quality of the obtained specimen. MATERIALS AND METHODS: A standard bone biopsy set was connected to a commercial drill to perform bone biopsies. Data was collected over a 2-year period (2015-2016). Information regarding technical success, diagnostic data and complication rates was all collated to assess the technical feasibility of this technique. RESULTS: Out of 357 bone biopsies, 34 patients underwent the procedure using a common orthopedic drill connected to a core biopsy needle. Diagnostic material was obtained in each patient and the artifacts were considered irrelevant. No major complications occurred in any patient. DISCUSSION: The use of a core biopsy needle connected to a common orthopedic drill facilitates the penetration of thick cortical bone by simply applying continuous speed and pressure; nevertheless, the biopsy needle we use is not designed for a drilling procedure and for this reason it can be damaged, but if the biopsy is performed with particular attention, the mechanical failure can be avoided CONCLUSIONS: Bone biopsy using a commercial hand drill has a technically high success rate with minimal complications. Further studies with more cases are necessary to verify our results.

ABSTRACT

This report describes a rare case of concurrent abdominal aortic aneurysm and bilateral renal ectopia. Preoperative work-up included intravenous pyelography and angiography to assess renal function, renal artery anatomy, and ureter position. Conventional surgery was performed without renal protection. No deterioration in postoperative renal function was observed.
