Comparative StudyA novel computer-assisted drill guide template for thoracic pedicle screw placement: a cadaveric study.
The objective of this study was to develop a novel, patient-specific, navigational template for thoracic pedicle screw placement. ⋯ We have developed a novel, patient-specific, navigational template for thoracic pedicle screw placement with good applicability and high accuracy.

Comparative StudyAngle stable locking nails versus conventionally locked intramedullary nails in proximal tibial shaft fractures: a biomechanical study.
A tibial nail with fixed-angle locking screws intends to combine the advantages of angular stability and intramedullary stabilization in extraarticular proximal tibial fractures. The goal of this study is to analyze if the angle stable tibial nail (ASN) is biomechanically more stable than an established conventional standard nail (CN). ⋯ No significant difference in stability between the two compared implants could be demonstrated. A trend could be shown indicating that the rate of nail loosening in the proximal osteotomized part of the bone was lower for the angle stable nail. This trend, however, could not be substantiated statistically.

Randomized Controlled Trial Comparative StudyClinical outcome after Chevron-Akin double osteotomy versus isolated Chevron procedure: a prospective matched group analysis.
Hallux valgus is a frequent condition of the forefoot, resulting in cosmetic deformity and pain. Chevron osteotomy (CO) is widely employed for the treatment of hallux valgus. Chevron-Akin double osteotomy (CAO) was previously described and superiority over an isolated Chevron procedure was assumed. The objective of this study was to compare the short-to-middle term outcomes of CO and CAO. ⋯ These findings indicate that Chevron-Akin double osteotomy is a save and practicable procedure for the treatment of mild-to-moderate hallux valgus. Superiority of combined Chevron-Akin procedure over an isolated Chevron osteotomy might be limited to distinct clinical settings, but should not be generally assumed.

Randomized Controlled TrialReactionary haemorrhage reduction with adrenaline infiltration in proximal tibial osteotomy: a randomized clinical study of safety and efficacy.
In corrective osteotomy, wound closure is undertaken with or without deflation of the tourniquet. Hypoxia from the tourniquet causes vasodilatation associated with reactionary haemorrhage and reduced haemoglobin concentration and possibly increased blood transfusion rate. Reactionary haemorrhage and related transfusion need can be reduced through vasoconstriction from adrenaline infiltration. ⋯ In conclusion, wound infiltration with adrenaline was effective in reducing the extent of reactionary haemorrhage and post-operative drop in haemoglobin concentration. There was no significant difference in the transfusion rates in both groups.

Occult hip and pelvic fractures and accompanying muscle injuries around the hip.
We investigated the incidence of occult hip and pelvic fractures and associated muscle injuries around the hip. ⋯ Occult hip and pelvic fractures were almost equally seen among 113 cases with suspected hip fracture but were negative on plain radiography. Different patterns of associated muscle injuries in cases of occult hip fracture and pelvic fracture suggest that the mechanism of hip fracture and pelvic fracture is possibly different.
