ABSTRACT
Deep fungal infections are rare in the upper extremity. Vessel and nerve infection, synovitis, tenosynovitis, myofasciitis, arthritis and osteomyelitis have been discovered in literature. Treatment in most cases includes surgical procedure and antifungal agent use. Amputation is the final, most devastating for patient's functionality, solution. Intravenous antifungal drugs, frequently followed by oral administration, are important ancillary agents both for the initial treatment and the prevention of recurrence. We therefore performed a review of the current literature, in order to assemble the dispersed results of different studies and clarify the various aspects of upper extremity fungal infections.
ABSTRACT
Background: The purpose of this study is to compare the vascularized bone flaps (VBF) that are used in operations for scaphoid non-union in smokers and non-smokers and to scrutinize if the better biological potential of the VBFs can counteract the negative influence of smoking on healing. Materials and Methods: Our study included articles published until 2016, with scaphoid non-union patients who were operated on with a VBF or a VBG. Results: Eighteen articles met eligibility criteria with 335 non-smokers and 136 smokers totally. Healing of the scaphoid non-union was significantly more probable in the non-smoking group (OR=5.54, p<0.001). Patients with avascular necrosis in the proximal pole of the scaphoid (AVNPP) and non-AVNPP showed that non-smoking favors a better healing rate in both of these subgroups (p<0.001 and p<0.001, respectively). Non-smokers have 11 times and the non-AVNPP patient's 7.7 times greater probability of healing of the non-union. Meta-analysis of the data for time for healing showed a longer time in the smokers' group by 2.46 weeks, though non-statistically significant. The analysis could not prove that smoking is a predisposing factor for the development of AVNPP (spearman=0.094, p<0.05). Despite that, preoperative smoking cessation proved to be an inadequate healing moderator (OR=3.5, p=0.268). Finally, VBFs showed a significantly better healing rate compared with nVBGs in smokers (p=0.001). Conclusions: A hand surgeon should always take into consideration that smoking negatively influences the healing potential of a scaphoid non-union despite the theoretically superior biological background that VBFs offer. In patients who refuse to quit smoking, a VBF may be considered a better choice than a conventional graft.

ABSTRACT
Background: We aimed to systematically review all papers examining floating elbow injuries in adults. Material and Methods: MEDLINE, Cochrane Bone, Joint and Muscle Trauma, PROSPERO, and Scopus databases were searched up to August 31, 2020. Included studies had as a primary or secondary outcome the functional outcomes after a floating elbow injury on patients aged 17 or older. Methodological quality of the included studies was assessed. Results: Thirty-two studies met the inclusion criteria. Patients were male at 73,1%. Median age of the patients was 33,0 years and median time of follow-up was 19,5 months. Articular surfaces were affected at 24,4%, whereas 51,2% of the fractures was open. Approximately, 34,9% of the patients suffered neural injury. Ipsilateral and multiple-system injuries were present in 34,8% and 76,3 % of the cases, respectively. Multivariate analysis showed that intra-articular and nerve damage, open fractures and multi-system injuries affected range of motion, union and complications. Sex, age, vascular damage and ipsilateral injuries of the patient did not adversely impact the outcome. All of the included studies were classified as very-low quality of evidence. Conclusions: The current knowledge regarding the characteristics of floating elbow in adults is limited, albeit we were able to provide possible pre-operative predictor outcomes.
