BACKGROUND: Osteochondral lesions of the talus (OLTs) are amongst the most common foot and ankle disorders. Varus ankle malalignment causes stress concentration on medial side of the joint, resulting in OLTs and osteoarthritis. For large symptomatic OLTs (>10 mm), Osteochondral autograft transplantation is usually recommended. This article highlights biplanar distal tibial osteotomy as an approach and management for patients with concomitant large OLTs and varus ankle malalignment...

Sergio Eustolio Hernández-Da Mota, Jorge Francisco Béjar-Cornejo
During a pars plana vitrectomy, an unplanned retinotomy in the raphe was performed in a 55-year-old female patient with rhegmatogenous retinal detachment and proliferative vitreoretinopathy. Since diathermy and laser therapy were not available at that moment, it was decided to peel off a small graft of the internal limiting membrane adjacent to the retinotomy site which had been previously stained with Brilliant Blue G. The graft was displaced under perfluorocarbon fluids and placed inside the retinotomy. Three weeks after surgery, the apparent closure of the retinotomy was observed clinically...

INTRODUCTION: Cierny-Mader (C-M) type IV chronic osteomyelitis represents a complex clinical challenge with permeation of extensive bone and soft tissue involvement. Aggressive debridement through viable tissue margin includes en bloc resection improves the odds of eradication of infection, which creates large bone and soft tissue loss in treating this type of osteomyelitis. The potentially large defects increase reconstruction problems with traditional reconstruction technique. The newly staged induced membrane technique presents length-independent, potential as an alternative reconstruction method for segmental bone defects due to type IV chronic osteomyelitis...

Objective: Burn injuries remain a large financial burden on the healthcare system. According to CDC statistics (2010), nonfatal and hospitalized burns in the U.S. cost $1.8 billion for an annual incidence of ∼486,000 cases. To date, no technique proves to be the ideal therapy of deep partial-thickness burns. In this study, we review a trial usage of ACell (ACell, Inc.) wound matrix on deep partial-thickness burns. Approach: Burn patients were admitted through the Vanderbilt Emergency Department. Three were consented to receive ACell therapy...

: Small-diameter synthetic vascular grafts have high failure rate due to primarily surface thrombogenicity, and effective surface chemical modification is critical to maintain the patency of the grafts. In this study, we engineered a small-diameter, elastic synthetic vascular graft with off-the-shelf availability and anti-thrombogenic activity. Polycarbonate-urethane (PCU), was electrospun to produce nanofibrous grafts that closely mimicked a native blood vessel in terms of structural and mechanical strength...

PURPOSE: Parathyroid autotransplantation during total thyroidectomy leads to higher rates of postoperative hypocalcaemia. It has been argued, however, that it prevents permanent hypoparathyroidism. The impact of autografted normal parathyroid gland fragments on long-term parathyroid status has not been assessed properly. To clarify this, the short- and long-term parathyroid function was assessed in patients with three glands remaining in situ after total thyroidectomy, in whom the fourth gland was either autotransplanted (Tx) or accidentally resected (AR)...

Osteoid osteoma (OO) is a benign tumor that it is not generally seen in the foot and even less frequently in the phalanx (2-4%). The diagnosis when its location is intra-articular is a challenge and often delayed because the symptoms mimic a real arthritis. We report a clinical case involving a 16-year-old male patient who complained of persistent pain of the interphalangeal joint (IPJ) of the left hallux. A juxta-articular OO of the condyle of the proximal phalanx was identified. The patient underwent surgery that included tumor removal preserving the articular cartilage...

Despite the spontaneous regenerative capacity of the peripheral nervous system, large gap peripheral nerve injuries (PNIs) require bridging strategies. The limitations and suboptimal results obtained with autografts or hollow nerve conduits in the clinic urge the need for alternative treatments. Recently, we have described promising neuroregenerative capacities of Schwann cells derived from differentiated human dental pulp stem cells (d-hDPSCs) in vitro. Here, we extended the in vitro assays to show the pro-angiogenic effects of d-hDPSCs, such as enhanced endothelial cell proliferation, migration and differentiation...

Osteomyelitis is an infectious process in bone that occasionally leads to bone destruction. Traditionally, the surgical treatment procedure is performed in combination with systemic and local antibiotics as a two-stage procedure that uses autograft or allograft bone for filling of the cavitary defect. Bioactive glass (BAG-S53P4) is a bone substitute with proven antibacterial and bone bonding properties.One hundred and sixteen patients who had verified chronic osteomyelitis was treated using BAG-S53P4 as part of the treatment...

Tears of the patellar and quadriceps tendon are common in the active population, especially in athletes. At present, several techniques for surgical repair and reconstruction are available. When reruptures occur, a reconstruction is mandatory. In the present paper, we describe a surgical technique for patellar and quadriceps tendon reconstruction using ipsilateral hamstring autograft. After routine hamstring tendon harvesting, the tendon ends are prepared using a whip stitch. A transverse tunnel is drilled in the midportion of the patella, the hamstring graft is passed through the patella, and firmly secured to the patellar tunnel openings with sutures...
