A pediatric patient presenting with an open forearm fracture with segmental defect is rare, and the pediatric orthopedic literature to guide treatment is sparse. There are several described methods to treat the defect, including bone grafting and bone transport techniques. In addition, there are reports of fibular regeneration after resection if the periosteum is left intact. We present a case report of complete regeneration of over half of a pediatric radial shaft with an intact periosteum, after traumatic extrusion from an open fracture...

Posttraumatic pelvic nonunions in combination with malposition are uncommon in the present-day era of modern pelvic surgery. The case describes a new surgical technique for treatment of the nonunion localized to iliosacral joint. A 42-year-old polytraumatized male presented with a pelvic fracture (type 61-C2.3) associated with a complex acetabular fracture. The patient was treated and the pelvis stabilized according to damage control principles (external fixation and pelvic C-clamp) and subsequently definitively treated according to principles of current pelvic surgery...

BACKGROUND: Variations in the amplitude of surface electromyograms (EMGs) are typically considered to advance inferences on the timing and degree of muscle activation in different circumstances. Surface EMGs are however affected by factors other than the muscle neural drive. In this study, we use electrical stimulation to investigate whether architectural changes in tibialis anterior (TA), a key muscle for balance and gait, affect the amplitude of surface EMGs. METHODS: Current pulses (500 μs; 2 pps) were applied to the fibular nerve of ten participants, with the ankle at neutral, full dorsi and full plantar flexion positions...

Non-union of the humeral shaft is infrequently noticed after surgical fixation. Sixty eight patients whose osteosynthesis of humeral shaft had failed leading to non-union were identified over a duration of 10 years from (January 2006 to December 2015). Clinical and radiographical follow-up was available for 64 patients (4 patients were lost for follow-up), with a mean age of 58 years (range 25-78 years). All patients had aseptic atrophic non-union of either: proximal shaft (n=12), mid shaft (n=38), and lower shaft (n=14)...

INTRODUCTION: Composite injuries of the volar surfaces of fingers are frequently associated with digital vessel and nerve damage. Flow-through glabrous flaps can provide esthetic tissue coverage as well as revascularization, and using a neurovascular flap, allows primary reconstruction of the digital nerve. METHODS: Between June 2010 and August 2014, we prospectively studied the use of Microsurgical flow-through glabrous flaps to achieve simultaneously digital revascularization and soft tissue coverage in 13 fingers of 12 patients who experienced volar injuries, comprising 6 great toe fibular flaps, 3 medial plantar flaps, 1 pedis medialis flap, and 3 hypothenar flaps...

Postero-lateral knee instability raises surgical challenges. Of the many available reconstruction techniques, few ensure anatomical reconstruction of the postero-lateral corner (PLC). The "Versailles" technique ensures the anatomical reconstruction of the three main PLC stabilisers (lateral collateral ligament, popliteus tendon, and popliteo-fibular ligament)by using either a hamstring autograft or a tendon allograft.

BACKGROUND: Following resection of large benign bone tumors surgeons are confronted with bone defects severely affecting the stability of a limb. To restore the mechanical continuity of the bone different treatment methods using bone grafts have been described. In pediatric patients the thick periosteal sleeve is thought to contribute to bone formation. HYPOTHESIS: An intact periosteal sleeve is crucial in bone remodelling around a non-vascularised fibular graft used to bridge large bone defects...

Forearm fractures in children complicated with non-union are uncommon. Various methods have previously been reported to manage this condition. Well documented techniques would include iliac crest grafting, cancellous insert grafting, ulnar segment grafting, cortical tibial grafting, vascularized fibular grafting and bone transport by ring fixation. The authors present a case of a child with an atrophic non-union of the ulna who was successfully treated with a cortico-cancellous tibial strut bone graft.

This evaluation involves an innovative muscle pump-activating device (geko™) as an adjunctive therapy with best practices for non-healing venous leg ulcers (VLUs). Stimulating the common peroneal nerve (at the fibular head), the geko™ device creates a response that acts as foot and calf muscle pumps, increasing venous, arterial and microcirculatory flow. The aim was to evaluate and determine if the geko™ is effective in this population and if it should be added to the medical supply formulary. In all, 12 patients with 18 recalcitrant VLUs (defined as less than 30% reduction in wound size in 30 days with best practices) in two community settings in Ontario consented to the evaluation and were treated with the geko™ for up to 20 weeks...

RATIONALE: Metacarpal and phalanx defects with soft tissue loss were suggested to be reconstructed by vascularized bone flap. The fibular osteocutaneous flap is a preferred method. Three-dimensional virtual planning has successfully applied in mandibular reconstruction with fibular free flap. We applied three-dimensional virtual planning in precise fibula flap harvest to maintain the continuity of the fibula and to achieve accurate metacarpal and phalanx reconstruction. PATIENT CONCERNS: A 35-year-old male presented with extensive soft tissue defects and first metacarpal defect involving the first metacarpophalangeal joint...

A 24-year-old womanpresented with ameloblastic fibrosarcoma arising from ameloblastic fibroma. The delayed presentation accounted for the extensive destruction of the mandible and complete occlusion of her oral cavity. This resulted in an inability to eat and maintain oral hygiene. A multidisciplinary team management approach involved nutritional optimisation, segmental mandibulectomy, reconstruction with a reconstructive plate and a free anterolateral thigh flap to line the the floor of mouth. Functional and aesthetic outcome was acceptable, and the patient is planned for secondary free fibular flap bony reconstruction...

Skeletal dysplasias are a complex group of more than 350 disorders with phenotypic and genotypic heterogeneity affecting bone and cartilage growth. We studied a 2-year-old girl and her 21-year-old mother with disproportionate short stature. In addition to typical features of hypochondroplasia found in both patients, the child had deformities of the extremity bones, metaphyseal flares, and bilateral transverse (Bowdler) fibular spurs with overlying skin dimples detected at birth. Intravenous pamidronate was started in the child since the age of 17 days, and then every two months...

BACKGROUND: We present a classification system that progresses in severity, indicates the pathomechanics that cause the fracture and therefore guides the surgeon to what fixation will be necessary by which approach. METHODS: The primary posterior malleolar fracture fragments were characterized into 3 groups. A type 1 fracture was described as a small extra-articular posterior malleolar primary fragment. Type 2 fractures consisted of a primary fragment of the posterolateral triangle of the tibia (Volkmann area)...

REVIEW
R Windhager, G M Hobusch, M Matzner
A combination of allogeneic and autologous bone transplants is frequently used for the biological reconstruction of bone defects. Autologous bone transplants can be used either in the form of structural or cancellous bone transplants. The osteogenic potential of autologous cancellous bone is well-known and is still the gold standard with respect to osteoinduction and remodelling. Structural transplants, such as fibular and tricortical iliac crest grafts can be transplanted either free, i.e. non-vascularized or vascularized with anastomosed vessels...

Benjamin T Himes, Thomas J Wilson, Andres A Maldonado, Naveen S Murthy, Robert J Spinner
The authors present a case of delayed peroneal neuropathy following a lateral gastrocnemius rotational flap reconstruction. The patient presented 1.5 years after surgery with a new partial foot drop, which progressed over 3 years. At operation, a fascial band on the deep side of the gastrocnemius flap was compressing the common peroneal nerve proximal to the fibular head, correlating with preoperative imaging. Release of this fascial band and selective muscle resection led to immediate improvement in symptoms postoperatively...

PURPOSE: Although free fibula flaps are widely used for mandibular reconstruction, 3-dimensional (3D) position is difficult to control in angle-to-angle mandibular defects. The present study describes a revised approach for angle-to-angle mandibular reconstruction with fibula flaps by using mandibular fixation device and surgical navigation. METHODS: Preoperative maxillofacial and fibular computed tomography (CT) scans were acquired, and CT data were imported into ProPlan CMF software...

BACKGROUND: There were many articles about double-barreled fibular flap for mandibular reconstruction. The upper layer bone was suit for implant placement as a new alveolar. The lower layer was necessary for contour. But the accurate relationship between the 2 layers bone was rarely reported. OBJECTIVES: The purpose of this study was twofold: to evaluate the feasibility of the novel design of the double-barreled fibular flap from virtual surgery to actual result; to evaluate the accuracy and results of occlusion-guided double-barreled fibular free flap in mandible reconstruction...
