Horizontal ridge augmentation with allografts has attracted notable attention because of its proper success rate and the lack of disadvantages of autografts. Corticocancellous block allografts have not been adequately studied on humans. Therefore, this study evaluated clinically and histomorphometrically the increase in ridge with after horizontal ridge augmentation using corticocancellous block allografts, and the implant success after 12 to 18 months post-implantation. In 10 implant patients (3 women, 7 men, 45 years old on average), defective maxillary alveolar ridges were horizontally augmented using freeze-dried bone allograft blocks...

Complex, full-thickness soft tissue defects secondary to large burns, trauma and war-related injuries continue to challenge reconstructive surgeons. To achieve positive surgical outcomes in these patient populations, novel approaches are needed to restore the functional, protective and aesthetic properties of skin. Herein, we provide the first report describing the staged use of a dermal regenerate template (DRT) with a spray-on epidermal regenerative modality (spray skin) in addition to autologous split-thickness skin grafting (STSG) in non-burn trauma and compare these results with those of patients treated with DRT and STSG alone...

PURPOSE: High-energy proximal tibial fractures often accompany compartment syndrome and are usually treated by fasciotomy with external fixation followed by secondary plating. However, the initial soft tissue injury may affect bony union, the fasciotomy incision or external fixator pin sites may lead to postoperative wound infections, and the staged procedure itself may adversely affect lower limb function. We assess the results of staged minimally invasive plate osteosynthesis (MIPO) for proximal tibial fractures with acute compartment syndrome...

INTRODUCTION: The integrity of the palatal mucosa can be lost due to congenital, pathological, and iatrogenic conditions. Various surgical techniques have been suggested for the closure of palatal defects. The aim of the current study is to present the free buccal fat pad graft as a novel technique to repair the soft-tissue defects at the palate. PATIENTS AND METHODS: During a 2-year period, the free fat tissue graft harvested from the buccal fat pad (BFP) (FBFG) and used to reconstruct five soft-tissue defects of the palate in five patients (2 women, 3 men; mean age, 34 years; range, 22-58 years)...

Digital technology has been widely used in the field of implant dentistry. From a surgical standpoint, computer-guided surgery can be utilized to enhance primary implant stability and to improve the precision of implant placement. From a prosthetic standpoint, computer-aided design/computer-assisted manufacture (CAD/CAM) technology has brought about various restorative options, including the fabrication of customized abutments through a virtual design based on computer-guided surgical planning. This case report describes a novel technique combining the use of a three-dimensional (3D) printed surgical template for the immediate placement of an implant, with CAD/CAM technology to optimize hard and soft tissue healing after bone grafting with the use of a socket sealing abutment...

Rehabilitation of segmental defects of maxilla presents a reconstructive challenge to obtain an ideal osseous form and height with adequate soft tissue investment. Though variety of prosthetic and surgical reconstructive options like the use of vascularized and non vascularized bone grafts are available they produce less than optimal results. Bone transport distraction is a reliable procedure in various maxillofacial bony defect reconstruction techniques. We describe herein a technique of maxillary bone transport distraction using an indigenously designed, custom made trifocal transport distractor performed in a post traumatic avulsive defect of the anterior maxilla...

Accurate tunnel placement is important for a successful anterior cruciate ligament (ACL) reconstruction. Controversy exists concerning the preferred method of femoral tunnel preparation, with proponents of both medial portal and transtibial drilling techniques. Current ACL literature suggests that placement of the femoral ACL attachment site posterior or "low" in the ACL footprint leads to more anatomically correct ACL mechanics and better rotational control. There is limited literature focusing on ACL graft displacement through knee range of motion based on specific paired placement of femoral and tibial tunnels...

BACKGROUND: Allograft tendons are frequently used for ligament reconstruction about the knee, but they entail availability and cost challenges. The identification of other tissues that demonstrate equivalent performance to preferred tendons would improve limitations. Hypothesis/Purpose: We compared the biomechanical properties of 4 soft tissue allograft tendons: tibialis anterior (TA), tibialis posterior (TP), peroneus longus (PL), and semitendinosus (ST). We hypothesized that allograft properties would be similar when standardized by the looped diameter...

BACKGROUND: Acute complex traumatic wounds of the lower limbs are usually managed by a combination of multiple debridements, dressing changes, and specialized surgical procedures which may include tissue transfers for the reconstruction of the soft tissue injury. The recovery is lengthy, and the outcome dependent on the initial injury, the surgical procedures undertaken and rehabilitation programs with a multidisciplinary team. METHOD: A nine-year-old male patient presented to Kimberly Hospital with an extensive soft tissue injury of the leg associated with a tibia fracture caused by a high velocity pedestrian vehicle accident...

BACKGROUND: The treatment of pilon tibia fractures is challenging. Anatomical reduction of the joint surface is essential. Excessive soft-tissue dissection may interfere with the blood supply and can result in nonunion. We sought to compare the outcomes of distal tibia fractures treated with medial locking plates versus circular external fixators. METHODS: We retrospectively evaluated 41 consecutive patients with closed pilon tibia fractures treated with either minimally invasive locking plate osteosynthesis (n = 21) or external fixation (EF) (n = 20)...

BACKGROUND: Autologous fat grafts and adipose-derived stem cells (ASCs) can be used to treat soft tissue defects. However, the results are inconsistent and sometimes comprise tissue resorption and necrosis. This might be due to insufficient vascularization. Platelet-rich plasma (PRP) is a source of concentrated autologous platelets. The growth factors and cytokines released by platelets can facilitate angiogenesis. The simultaneous use of PRP might improve the regeneration potential of fat grafts...

Micro-computed tomography (microCT) is commonly used to characterize the three-dimensional structure of bone graft scaffolds before and after implantation in order to assess changes occurring during implantation. The accurate processing of the microCT datasets of explanted β-tricalcium phosphate (β-TCP) scaffolds poses significant challenges because of (a) the overlap in the grey values distribution of ceramic remnants, bone, and soft tissue, and of (b) the resorption of the bone substitute during the implantation...

INTRODUCTION: Spider bites as the cause of necrotic skin and soft tissue lesions occur very rarely in Central and Northern Europe. Recluse spiders, distributed almost worldwide, are one of two genera of spiders with confirmed capability of causing necrotic lesions. In the facial region, the resulting defects represent a potential reconstructive challenge, especially in younger patients. METHODS: This case report has been reported in line with the SCARE criteria...

About 90 % of all cases of painful posttraumatic ankle arthritis can be very successfully treated with a minor invasive ankle arthrodesis technique by using a small anterior approach and a fixation with four 6. 5 mm screws of which the posteromedial and transfibular one are inserted percutaneously. The results with this standardized procedure have been reported previously as excellent and good in a mid-term run of 6 years (34). This technique leads to a high union rate of 99% (92 of 93) with rapid bone healing within 8 ± 2 weeks, it causes a low minor complication rate of 8 % and enables a significant increase of the AOFAS ankle/hindfoot score (17) from 36 preoperatively to 85 postoperatively as well as a midtarsal movement of 24° ± 16°...
