OBJECTIVE There has been a recent renewed interest in the use and potential applications of 3D printing in the assistance of surgical planning and the development of personalized prostheses. There have been few reports on the use of 3D printing for implants designed to be used in complex spinal surgery. METHODS The authors report 2 cases in which 3D printing was used for surgical planning as a preoperative mold, and for a custom-designed titanium prosthesis: one patient with a C-1/C-2 chordoma who underwent tumor resection and vertebral reconstruction, and another patient with a custom-designed titanium anterior fusion cage for an unusual congenital spinal deformity...

Background Different advantages of virtually planned and guided mandibular reconstructions have been described. Functional analyses and comparisons with conventionally reconstructed patients. Methods We retrospectively analyzed 30 cases of mandibular reconstructions that involved virtually planned or conventional microvascular, fibular free flaps that occurred between April 2011 and December 2014 at a single center. The results were also compared with a healthy cohort of 30 participants. Axiographic measurements were performed postoperatively, and uni- and multivariate regressions analyses were performed to determine the association between possible predictor variables on functional outcome...

Background Free vascularized fibular flaps (FVFFs) are accepted surgical options to treat osteonecrosis of the femoral head and neck (ONFHN) to prevent conversion to total hip replacement (THR), yet many studies are single institution cohorts, with little generalizability. Purpose The purpose of this study was to perform a systematic review examining the comparative effectiveness of FVFF to treat ONFHN, particularly preventing conversion to a THR and improving hip function/symptoms. Methods We searched PubMed and EMBASE databases using femoral head, free fibula, and femoral neck keywords...

BACKGROUND: No general consensus has yet been established for the gold standard treatment of ankle syndesmotic complex injuries. Recent literature has documented the success of ankle tightrope fixation for heterogeneous ankle fracture patterns, resulting in syndesmotic complex injuries. We present a multicentre case series assessing the clinical, radiological and functional outcomes of patients with Weber C ankle fractures treated with the Arthrex TightRope(®) fixation system. METHOD: We performed a retrospective analysis of all adult patients with Weber C ankle fractures who were treated with the Arthrex TightRope(®) fixation system at four centres over a 3-year period...

PURPOSE: The posterior malleolar fracture (PMF) in tibial spiral fractures are a common type of complication that occurs in tibial fractures. However, the indication of fixation for posterior fractures is still under debate and varies between different surgeons'. It is not unusual to find the smaller PMF (<25%), which could be treated conservatively within guidelines, treated with internal fixation in clinic. The aim of this study is to evaluate the clinical outcomes of tibial spiral fractures with PMF and provide proper guidance for the treatment of this special fracture...

To explore the techniques for mandibular reconstruction with composite free flaps and their outcomes, we systematically reviewed reports published between 1990 and 2015. A total of 9499 mandibular defects were reconstructed with 6178 fibular, 1380 iliac crest, 1127 composite radial, 709 scapular, 63 serratus anterior and rib, 32 metatarsal, and 10 lateral arm flaps including humerus. The failure rate was higher for the iliac crest (6.2%, 66/1059) than for fibular, radial, and scapular flaps combined (3.4%, 202/6018) (p<0...

Bin Yang, Yi Qu, Ming Su, Jinzhong Li, Hua Li, Rudong Xing, Zhengxue Han
BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

Microsurgical reconstructive techniques have revolutionized the treatment of large head and neck defects. These defects were once forever life altering because of the considerable morbidity to both the form and function of the patient. As time has progressed, microsurgical technique has improved dramatically and has become institutionalized in our training programs. Free flap outcomes in head and neck reconstruction have improved dramatically, and optimization of these outcomes is now key. One overlooked area has been neurosensory reconstruction...

AIMS: Free vascularised fibular grafting has been used for the treatment of large bony defects for more than 40 years. However, there is little information about the risk factors for failure and whether newer locking techniques of fixation improve the rates of union. The purpose of this study was to compare the rates of union of free fibular grafts fixed with locking and traditional techniques, and to quantify the risk factors for nonunion and failure. PATIENTS AND METHODS: A retrospective review involved 134 consecutive procedures over a period of 20 years...

PURPOSE: Condylar reconstruction and replacement using alloplastic materials currently attracts much surgical interest. The major challenge is to functionally reconstruct the anatomical region; this is crucial in terms of correct mandibular function. The goal of the present study was to evaluate the clinical outcomes of and complications experienced by a series of oncological patients who underwent computer-aided design/computer-aided manufacturing (CAD/CAM) condylar reconstruction following resection-disarticulation of the mandible...

BACKGROUND: Fibular tendon dislocation is a rare and usually sports-related injury. We report the functional and ultrasonographic outcomes of a simple technique for re-tensioning the superior fibular retinaculum. HYPOTHESIS: Our retinaculum re-tensioning technique is not followed by recurrent fibular tendon dislocation, as demonstrated by ultrasonography. MATERIAL AND METHOD: This single-centre single-surgeon retrospective study included 17 patients who underwent surgery to treat fibular tendon dislocation between January 2008 and December 2013...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

We aimed to show that the star excursion balance test can identify instability in the ankle of patients who have had harvest of a fibular free flap. We compared the reach distance of the operated leg against that of the non-operated leg in 26 patients who had had harvest of the flap over a period of three years from August 2009 at two different centres. The goal of the test is to reach as far as possible with one leg in eight directions while balancing on the other. We also assessed the overall function of the operated leg using the Foot and Ankle Disability Index (FADI) and the American Orthopaedic Foot and Ankle Score (AOFAS)...
