BACKGROUND Guided bone regeneration (GBR) using a non-absorbable barrier has provided clinicians the ability to place implants in sites compromised by insufficient bone, including immediate extraction sites. Recent evidence suggests that successful GBR outcomes may be possible using bioabsorbable polymer barriers. METHODS This report presents a case series of 9 patients with 8 fenestration an...

INTRODUCTION Chronic patellofemoral instability occurs mainly in adolescent females and can also be induced by medial patellofemoral ligament (MPFL) injury. There are no case reports of MPFL reconstruction for chronic patellofemoral instability due to MPFL injury in aged populations. CASE PRESENTATION 81-year-old female presented with left knee pain, giving way, and patellar instability while...

OBJECTIVE To assess the safety and efficacy of accelerated compared with traditional postoperative weightbearing (WB) rehabilitation following matrix-induced autologous chondrocyte implantation (MACI) of the knee, using MRI. METHODS A randomized controlled study design was used to assess MRI-based outcomes of MACI grafts in 70 patients (45 men, 25 women) who underwent MACI to the medial or la...

PURPOSE Evaluation of the healing and persistence of a meshed composite skin graft applied without immunosuppression. METHODS The contraction of wounds grafted with 9:1 split-thickness autograft/1.5:1 allodermal mesh composite skin grafts (auto/allo MCSGs) was investigated. No immunosuppressive agent was applied. Male ACI rats and female Lewis rats reciprocally served as allodermis graft dono...

Three-dimensional (3D) engineered tissue constructs are a novel and promising approach to tissue repair and regeneration. 3D tissue constructs have the ability to restore form and function to damaged soft tissue unlike previous methods, such as plastic surgery, which are able to restore only form, leaving the function of the soft tissue often compromised. In this study, we seeded murine myoblas...

Beta-tricalcium phosphate ( β -TCP) and hydroxyapatite (HA) are widely used as bone graft extenders due to their osteoconductivity and high bioactivity. This study aims to evaluate the possibility of using porous substrate with composite ceramics ( β -TCP: HA = 60% : 40%, 60TCP40HA) as a bone graft extender and comparing it with Bio-Oss. Interconnectivity and macroporosity of β -TCP porous subs...

DESCRIPTION A 61-year-old man presents with invasive basal cell carcinoma of the scalp. Composite resection results in a 280-cm 2 scalp defect of the outer and inner table. Titanium mesh was used to reconstruct the calvarial defect, while reconstruction of the scalp wound was accomplished with a free latissimus dorsi (LD) flap plus split-thickness skin graft.

We presented a technique for using the St. Jude Aortic Connector System in anastomosis with a composite graft of saphenous vein and radial artery. This technique has not been reported in the previous literature. Our technique could improve some disadvantages of the St. Jude Aortic Connector and allow this device to be used in off-pump coronary artery bypass grafting (OPCAB).

We present two cases of serratus anterior free fascial flap combined with vascularized scapular bone graft for reconstruction of traumatized dorsal hand and phalangeal bone defects. Composite flaps with single vascular pedicles allowed conservation of severely injured fingers and provided good functional and cosmetic outcomes.

A 13-year old girl, who had undergone arterial switch operation using the Lecompte manoeuvre for TGA, developed aortopulmonary fistula derived from the balloon angioplasty for pulmonary artery (PA) stenosis (Fig. 1A–C). Because the adhesive tissue prevented cardiac tamponade, elective surgical repair including PA reconstruction using a composite graft was successfully done several days after re...
