Bone metastasis to the foot: report of three cases
No full textBone metastases to the foot are rare and often misdiagnosed. Only tarsal localizations are relatively frequent. Primary tumours are mostly adenocarcinomas (colon, kidneys, lungs). Three cases of acrometastases, localized, respectively, on the ungual phalanx of the hallux, the first metatarsal and the first cuneiform, are reported. Primitive tumour sites differed in the three cases (renal, pulmonary and mammary origin). Adequate therapy must be preceded by an accurate staging. Surgery should aim to excise the tumour and restore, when possible, a good function of the foot without any pain. Amputation should only be resorted to if is not possible to perform the excision of the tumour in patients whose life expectancy is not too short. Wide local and systemic diffusion of the tumour and a short life expectancy contraindicate any surgical approach. Treatment, in these cases, must try to achieve a satisfactory pain control and decrease the local expansion of the tumour

No full textSuperior capsular reconstruction of the shoulder: the ABC (Arthroscopic Biceps Chillemi) technique.
Full text linkSuperior capsular reconstruction (SCR) demonstrated its efficacy as a treatment option available in patients affected with irreparable posterosuperior rotator cuff tears without any signs of arthritis. Originally, the fascia lata autograft was fixed medially to the glenoid (with two or more anchors) and laterally to the greater tuberosity (with a compression double-row technique using four anchors or three transosseous tunnels). Additionally, side-to-side sutures were used to anteriorly and posteriorly connect the graft to the native residual rotator cuff tissue. However, the fascia lata as an autograft has a disadvantage related to the donor-site morbidity. To solve this aspect, allografts were employed with initial promising results. Nowadays, SCR is to be considered a technically demanding and expensive procedure, because of the cost of the allograft plus that of all the anchors employed to fix it. The Arthroscopic Biceps Chillemi's technique addresses these concerns in performing SCR and presents numerous advantages being a safe, easier, time and cost-saving way compared to the other published techniques. This technique has only one conditio sine qua non: the presence of the long head of the biceps tendon (LHB), used as an autograft. This condition may be interpreted as a disadvantage of this procedure in the presence of some anatomic variations of the intra-articular portion of the LHB and the very rare absence of the tendon or in case of partial or complete rupture of the LHB tendon associated with a rotator cuff tear

Arthroscopic repair of massive rotator cuff tear. The role of the LHB distal tenotomy
No full textPurpose: The aim of the study was to evaluate the results of an all arthroscopic technique for the treatment of massive rotator cuff tears using the long head of biceps as a graft to reconstruct the superior capsule and to reinforce the cuff. Methods: A retrospective review of a consecutive series of arthroscopic repair of massive rotator cuff tears using the long head of biceps tendon was conducted. Twenty-five patients underwent surgery, and none were lost at follow-up. Minimum follow-up period was more than 12 months. Constant, UCLA and VAS scores as clinical outcome were analyzed. Time for surgical procedures was also registered. Two alternative procedures (transosseous or anchors) were employed to fix laterally the long head of biceps to the greater tuberosity and to reinforce the cuff. This choice was essentially determined by the bone quality of the greater tuberosity. Results: All patients of both groups (Transosseous: 15 and Anchors: 10) showed a significant improvement of clinical and functional scores. Difference of the operative times between two procedures was statistically significant in favor of the anchor approach. No intraoperative complications were recorded. Postoperative shoulder stiffness was found in two male patients. In no case biceps tenodesis was performed: Popeye sign was easily detected in 16 patients but they did not complain any superior arm pain and weakness. Conclusion: This technique represents a valid solution for treatment of massive rotator cuff tears resulting safe, easier and cost saving in comparison with other published techniques
