Kristopher B McCall, David Y Chong
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...

Proximal humerus fracture after pectoralis major tendon repair has been recently reported. Although this complication is rare, it may be possible to decrease such risk using newer techniques for myotenodesis. This study was designed to evaluate various unicortical stress risers created at the proximal humeral metadiaphysis during myotenodesis for repair of pectoralis major ruptures. A simulated pectoralis major myotenodesis was performed using fourth-generation Sawbones (N=30). Using previously described anatomic landmarks for the tendinous insertion, 3 repair techniques were compared: bone trough, tenodesis screws, and suture anchors (N=10 each)...

INTRODUCTION: Cervical spine injury classification systems should be simple, easy to relate and remember, reliable guide for surgical planning, and predictor of outcome in clinical settings. We investigated whether the AOSpine subaxial cervical spine classification system predicted injury severity and neurologic outcome. MATERIAL AND METHODS: We analyzed the relevant clinical, imaging, management, and American Spinal Injury Association (ASIA) impairment scale (AIS) grade conversion of 92 AIS grades A-C patients with cervical spine injury...

Chondromyxoid fibromas (CMFs) are rare, benign, primary tumors of bones, and occur in the metaphyses of the medullary canals of the long bones. The occurrence of intracortical CMFs is extremely rare. Very few cases of intracortical CMFs located in the long tubular bones have been reported to date. Moreover, even though the feet are the second most common site for CMF (after the knees), intracortical metatarsal CMF has not been reported previously, to our knowledge. We report an intracortical CMF occurring in the diaphysis of the metatarsal in a 17-year-old man...

INTRODUCTION: The three currently used methods of treatment: namely open reduction plate osteosynthesis (ORPO), Minimally invasive plate osteosynthesis (MIPO), antegrade intramedullary nailing(IMN) are all reported as satisfactory procedures for treatment of humeral shaft fractures. However none of the published reports have a comparison of superiority of one procedure over the other. We evaluated the clinical, radiological and functional outcome of the three procedures. MATERIALS AND METHODS: We studied adult patients with humerus shaft fractures over a period of 2 years from May 2014 to May 2016 in a level 1 trauma center...

BACKGROUND: Infected non-union is complex and debilitating disorder affecting orthopaedic surgeon and patient in terms of cost and time. Many methods are described in the literature for treatment of infected non-union. Local high concentration of antibiotic and mechanical stability of antibiotic cement impregnated intramedullary nail (ACIIN) proves cost and time effective. Recently it was suggested that ACIIN can achieve both union and infection control in infected non-unions with bone gap less than 4cm...

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: Non-union following interlocking nailing is a troubling complication in treatment of shaft femur fractures. There is no clear consensus on the treatment of this problem. This research was undertaken to study the role of augmentation plating combined with exchange nailing in such cases. PATIENTS AND METHODS: A prospective clinical study was undertaken from January 2010 to December 2015. Patients with aseptic femoral shaft non-union, with or without implant failure following intramedullary nailing were included in the study...

BACKGROUND: Unstable intertrochanteric fractures present a challenge to orthopaedic surgeons, with varied geometry of the fractures and a wide choice of implants and techniques. The patients are usually osteoporotic, with multiple co-morbidities and poor tolerance for complications and re-operations. Lateral wall reconstruction and stability of the trochanteric fragments are considered important in providing a better outcome of these difficult injuries. We present a technique of lateral wall and trochanteric reconstruction using Cerclage wires and lag screws in the greater trochanter in addition to intramedullary nailing, and the radiological and functional outcome of this technique of augmentation...

We aimed to test whether a robotic technique would offer more accurate access to the proximal femoral medullary cavity for insertion of an intramedullary nail compared to the conventional manual technique. The medullary cavity of ten femur specimens was accessed in a conventional fashion using fluoroscopic control. In ten additional femur specimens, ISO-C 3D scans were obtained and a computer program calculated the ideal location of the cavity opening based on the trajectory of the medullary canal. In both techniques, the surgeon opened the cavity using a drill and inserted a radiopaque tube that matched the diameter of the cavity...

BACKGROUND: Intramedullary fixation of comminuted mid-shaft clavicle fractures has traditionally been employed with satisfactory clinical outcomes; however, pins with smooth surfaces may protrude from the bone and are prone to migration, while some threaded pins are difficult to remove post-operatively. The aim of this proof-of-concept study was to develop and evaluate the biomechanical strength of a novel intramedullary Echidna pin device designed to maintain fracture reduction, resist migration and facilitate ease of post-operative removal...

John G Birch
In the last 35 years, orthopaedic surgeons have witnessed 3 major advances in the technique of limb lengthening: "distraction osteogenesis" facilitated by Gavriil Ilizarov method and infinitely-adaptable circular fixator with fine-wire bone fragment fixation; the introduction of the "6-strut" computer program-assisted circular fixators to effect complex deformity correction simultaneously; and the development of motorized intramedullary lengthening nails. However, the principles and associated complications of these techniques are on the basis of observations by Codivilla, Putti, and Abbott from as much as 110 years ago...

OBJECTIVE Chondrodysplasia punctata (CDP), a rare skeletal dysplasia, can lead to cervical spine instability and deformity. However, an optimal neurosurgical intervention has yet to be established. Thus, a retrospective study was conducted to assess the efficacy of various surgical interventions for children with CDP. METHODS The authors retrospectively reviewed 9 cases of CDP in which cervical decompression with or without posterior fusion was performed between April 2007 and May 2016. Patient demographics, preoperative clinical conditions, radiographic findings, surgical procedures, and the postoperative course were analyzed in detail...
