Introduction: In terms of access to treatment of acromioclavicular joint injuries, there are many controversies, especially after the appearance of works that promote "neglecting of injury". Goal: The aim of this paper is to give a comparative analysis of the results of rehabilitation of patients after acute injury of the acromioclavicular joint of the third degree, treated by two surgical techniques: by Phemister and Vukov. Material and methods: In this study, we investigated a total of 60 operated patients: 30 patients were operated by Phemister technique, and 30 by Vukov technique. Results: Postoperative follow-up lasted for one year. Between these two groups, the time when the rehabilitation process began is significantly different p<0.01. With technique by Vukov, the rehabilitation begins on the first postoperative day and with technique by Phemister it begins later (after 7 weeks outpatient). With technique by Phemister, rehabilitation lasted on average 60 days, and with technique by Vukov on average 40 days. The duration of recovery is also significantly different p< 0.01, with technique by Vukov the duration time is shorter, and therefore the process of rehabilitation in days - is shorter than with the other technique. Both techniques gave good stability of the lateral end of clavicle. The difference was not statistically significant p> 0.05, which means that both techniques can be applied depending on the indication and the experience of the surgeon.

Aim. To develop a method of acromioclavicular joint stabilization with the TightRope system using «mini-open» technique and to evaluate effectiveness and safety of this surgery. Methods. The study involved 11 patients with Rockwood type III, IV and V acromioclavicular joint dislocation, who underwent «mini-open» surgery of acromioclavicular joint stabilization using the TightRope device. The results were evaluated clinically using the Constant scale and radiologically 3, 6, and 12 months after the treatment. The results obtained were statistically processed and compared to the results of the treatment of patients with the same pathology published in the foreign literature. Results. In the early postoperative period (up to 3 months after the surgery) functional result according to Constant scale in the studied patients varied in the score range of 67.5±16.2. In the period of up to 12 months all patients had 82.5±11.5 score, which corresponds to good and excellent results and does not show significant difference compared to the arthroscopic technique (according to literature data). Complications among observed patients occurred in 18% and were identified in 2 patients (1 case of fixation loss, 1 local skin inflammation in the area of the wound). Conclusion. New surgical techniques allow achieving good and excellent functional results and to improve patient satisfaction.

Introduction. Bone regenerates mainly by periosteal and endosteal humoral and cellular activity, which is given only little concern in surgical techniques and choice of bone grafts for guided bone regeneration. This study investigates on a clinical level the biomechanical stability of augmented sites in maxillary bone when a new class of moldable, self-hardening calcium-phosphate biomaterials (SHB) is used with and without the addition of Platelet Rich Fibrin (aPRF) in the Piezotome-enhanced subperiosteal tunnel-technique (PeSPTT).Material and Methods. 82 patients with horizontal atrophy of anterior maxillary crest were treated with PeSPTT and randomly assigned biphasic (60% HA/40% bTCP) or monophasic (100% bTCP) SHB without or with addition of aPRF. 109 implants were inserted into the augmented sites after 8.3 months and the insertion-torque-value (ITV) measured as clinical expression of the (bio)mechanical stability of the augmented bone and compared to ITVs of a prior study in sinus lifting.Results. Significant better results of (bio)mechanical stability almost by two-fold, expressed by higher ITVs compared to native bone, were achieved with the used biomaterials and more constant results with the addition of aPRF.Conclusion. The use of SHB alone or combined with aPRF seems to be favourable to achieve a superior (bio)mechanical stable restored alveolar bone.

Background A number of surgical techniques for the treatment of acromioclavicular joint separations have been described; however, few have been able to create a strong intra-operative construct that provides minimal joint translation. A biomechanical study was conducted to examine joint translation in an independent acromioclavicular ligament repair. Methods Three variations of a novel independent acromioclavicular ligament repair technique underwent testing using a Sawbones model. The technique involves threading sutures through two acromial bone tunnels in a suture-bridge configuration and anchoring them into the distal clavicle. Three groups of eight specimens underwent reconstruction; group 1 using FiberTape, group 2 using FiberWire and group 3 using FiberTape in a modified (under-over) suture-bridge configuration. Superior, anterior and posterior translation was tested at loads of 10, 20 and 30 N. Results Group 3 repair yielded the least translation in both anterior–posterior and superior–inferior planes, with a two-fold decrease in superior translation compared to groups 1 and 2 (P < .05). Both groups 1 and 3 using FiberTape resulted in significantly less anterior and posterior translation compared to the FiberWire group (P < .05). Discussion The independent acromioclavicular ligament repair, without repair of the coracoclavicular ligament, demonstrated significant translational stability in the anterior–posterior and superior–inferior planes.

Anhand der Pseudozysteneinteilung nach D'Egidio und Schein werden die verschiedenen chirurgischen Techniken der Pseudozystendrainage und -resektion diskutiert. Die Möglichkeiten und Grenzen der laparoskopischen Technik werden dargestellt. Auf die "Konkurrenz" der endoskopischen und interventionellen Therapien wird lediglich am Rand verwiesen. Prognostisch hängt der weitere Verlauf nach Pseudozystenoperation weniger von der Operationstechnik, als vom natürlichen Verlauf der Erkrankung (chron. Pankreatitis) und vom Sistieren, bzw. Weiterbestehen der zugrundeliegenden Noxe ab.

The treatment of metastatic spinal cord compression is complex. The three treatment modalities that are currently applied (in a histologically non-specific manner) are surgery, radiotherapy and the administration of steroids. The development of new spinal instrumentations and surgical approaches considerably changed the extent of therapeutic options in this field. These new surgical techniques have made it possible to resect these tumours totally, with subsequent vertebral reconstruction and spinal stabilization. In this respect, it is important to clearly identify those patients who can benefit from such an extensive surgery. We present our management algorithm to help select patients for surgery and at the same time identifying those for whom primary non-surgical therapy would be indicated. The retrospective review of surgically treated patients in our department in the last four years reveals a meagre application of conventional guidelines for the selection of the appropriate operative approach in the surgical management of these patients. The reasons for this discrepancy are discussed.
