The purpose of this work is to present our experience in management and the results of operative treatment of volar retinacular ganglions. One-hundred-and-seven patients were operated-on for volar retinacular ganglions between 2000 and 2014. One-hundred-and-eight ganglions were resected. Complications which were observed in five patients postoperatively (digital nerve irritation, restricted range of motion of digital joints) resolved within several weeks. At final follow-up, no ganglion recurrence, impairment of finger mobility, innervation or blood supply were observed in any of the patients.

The aim of this work is to present our experience in operative treatment of benign nerve tumours located in the hand. Special emphasis has been put on determining the occurrence rates of particular tumour types characterized by their unique histopathological patterns and describing detailed location of the lesions. The obtained results of treatment were assessed. The study comprised of 26 patients, both female (19) and male (7). The mean age and age range of the female and male patients were 44.8 years (range, 21-73 years) and 39.6 years (range, 21-74 years), respectively. The patients underwent operative treatment for tumours of neurogenic origin located in the hand between the years 1990 and 2013. In total, 31 tumours in 26 patients were removed. The most common site of tumour origin was small cutaneous branches and only exceptionally the tumours arose from common digital nerves (2 patients). No patient was lost to postoperative follow-up. The shortest period of postoperative follow-up covered 1 year. No tumour recurrence was detected during postoperative follow-up examinations. The patients reported neither pain nor presence of paraesthesias. Neurofibromas (17 tumours) predominated in the gathered clinical material, while the second most common group of tumours were schwannomas (12 tumours). (1) Benign nerve tumours of the hand are rare. Neurofibromas and schwannomas predominate among them. Tumours having other histopathological patterns are extremely uncommon. (2) The prognosis after resection of benign nerve tumours located in the hand is good and the risk of postoperative complications and recurrence is low.

The incidence of traumatic glenohumeral dislocation ranges from 8.2 to 26.69 per 100 000 population per year. The most common complication is recurrent dislocation occurring in 17-96% of the patients. The majority of patients are treated conservatively by closed reduction and immobilization in internal rotation for 2-3 weeks. However, no clear conservative treatment protocol exists. Immobilization in external rotation can be considered an alternative. A range of external rotation braces are commercially available. The purpose of this work was to review the current literature on conservative management of glenohumeral dislocation and to compare the results of immobilization in internal and external rotation. A comprehensive literature search and review was performed using the keywords "glenohumeral dislocation", "shoulder dislocation", "immobilization", &quo...

However, in some patients the symptoms can persist and require operative intervention. This work aims to determine the risk factors for persistent BPIs resulting from shoulder dislocation. The study comprised 73 patients (58 men, 15 women; mean age: 50 years) treated operatively between the years 2000 and 2016 for persistent BPIs resulting from shoulder dislocation. Patient age, gender, type of initial trauma, number of affected nerves, presence of accompanying injuries, and time interval from dislocation to its reduction were analysed. Elderly patients more often sustained multiple-nerve injuries, while single nerve injuries were more often observed in younger patients. Injury to a single nerve was diagnosed in 30% of the patients. Axillary nerve was most commonly affected. Fracture of the greater tuberosity of humerus coincided with total BPI in 50% ...

The properties of both biopolymers allow their wide use in medicine and various industries. This paper presents the possibilities offered by chitin and chitosan for the creation of neurotubes utilized in peripheral nerve repair procedures. In the initial part of this manuscript, experimental studies on both polysaccharides carried out by numerous authors have been presented and their results have been discussed. Further, basic information on Reaxon® Nerve Guide, being the first chitosan tube approved for clinical use, is provided. Finally, existing limitations in the optimal use of chitosan tubes in peripheral nerve reconstruction have been pointed out. It is expected that modification of the properties of chitosan itself as well as enriching neurotubes with components of extracellular matrix, cells, growth factors and filaments will further improve the results of nerve...
