Value of the Two-Point Discrimination Test: Evaluation of 238 Isolated Finger Nerve Injuries.

It may be difficult to diagnose a nerve injury on a finger or a hand under emergency settings. The goal of this study was to elaborate whether the clinical testing of two-point discrimination was a safe and reliable method in the diagnosis of acute finger nerve injuries. Through a retrospective assessment, patients' records were analyzed whether the result of the two-point discrimination test corresponded with the intraoperative findings of a damaged nerve.

[SL fusion - no alternative for the treatment of chronic scapholunate dissociation].

Indroduction: The treatment of chronic scapholunate dissociation (SLD) is currently uneven and still presents a major challenge. Both, the primary ligament suture and frequently applied ligament reconstruction techniques cannot provide a permanent stable connection between the scaphoid and lunate. For this reason, the present study evaluates the value of a bony compound as a treatment option for the treatment of chronic SLD.

Changes in the Biomechanical Properties of Human Skin in Hyperthermic and Hypothermic Ranges.

Introduction: The prevalence of thermal skin injuries is high. Despite new research findings, skin burns and acute cold-contact injuries, together with resulting tissue damage, are not entirely understood. In particular, little is known about how these types of injuries alter the biomechanical properties of skin.

[Tissue engineering of adipose tissue with biodegradable biomaterials for soft tissue reconstruction].

Soft tissue defects resulting from injuries, tumor resection, congenital anomalies or chronic wounds pose a great challenge to reconstructive surgery. The current gold standard in therapy of such defects is the tissue transplantation in terms of free or local flaps. Unfortunately, donor site morbidity remains a considerable risk of flap surgery.

Analysis of Operative Techniques of Fractures of the First Metacarpal Base.

Introduction: Over time, the operative treatment of extra-articular and intra-articular fractures of the first metacarpal base has gained significant importance, and at present, there are many operative strategies available because of the different osteosynthesis procedures in practice today.

Purpose: In this retrospective cohort study, we analyze the possible differences between 2 distinguished operative osteosynthesis techniques, in terms of patient outcome, operation time, duration of radiation exposure, and postoperative radiographic results.

Methods: Fifty-two patients operated on for first metacarpal extra-articular or intra-articular base fracture were investigated retrospectively by means of records.

[Preservation of the outer ear in a complex burn injury].

Saving the outer ear in burn injuries is a challenging task for the treating surgeon that should not be underestimated. Burns which are initially evaluated as superficial, particularly in this region, often have a tendency to undergo progressive tissue destruction whereby conservative treatment is often no longer sufficient to preserve the skin of the auricle with the underlying cartilage. Various possibilities for saving the ear and for ear reconstruction are described, but in the case of severely burned patients it is often necessary to carry out a quick and relatively simple treatment.

A Quantitative Analysis of Microcirculation in Skin Defects Covered with Topical Wound Dressings or a Newly Developed Collagen Matrix.

Methyl Iodide Exposure Presenting as Severe Chemical Burn Injury with Neurological Complications and Prolonged Respiratory Insufficiency.

Methyl iodide (iodomethane) is a monohalomethane that is mainly used as an intermediate in the manufacturing of different pharmaceuticals and pesticides. Until now, only 13 cases of methyl iodide poisoning have been described in the literature. The authors present the first case of severe chemical burn injury due to methyl iodide exposure in a 36-year-old Caucasian man who suffered superficial to partial-thickness burn injuries over 75% of his BSA and developed neurological malfunctions and prolonged respiratory insufficiency.

Analysis of the microcirculation after soft tissue reconstruction of the outer ear with burns in patients with severe burn injuries.

Reconstruction of soft tissue defects of the ear with burns remains one of the most difficult tasks for the reconstructive surgeon. Although numerous reconstructive options are available, the results are often unpredictable and worse than expected. Besides full and split skin grafting, local random pattern flaps and pedicled flaps are frequently utilized to cover soft tissue defects of the outer auricle.

Improvement of Split Skin Graft Quality Using a Newly Developed Collagen Scaffold as an Underlayment in Full Thickness Wounds in a Rat Model.

Introduction: Frequently, full thickness skin defects were treated through split skin graft (SSG) transplantation. However, this is usually associated with a reduction of skin quality and scarring. In this context, a newly developed collagen cell carrier (CCC) has been evaluated as an underlayment in SSG transplantations in a rat model.
