Seidel intramedullary nailing of humeral diaphyseal fractures: a preliminary report

Forty-two humeral diaphyseal fractures in 41 patients were treated at three centers between April 1988 and November 1989. There were 28 acute fractures; four were open. Average time to union was 8 weeks. There were no infections. Six patients with seven pathologic fractures due to metastatic disease died during the course of this study, but the nail had allowed them to be functional with minimal surgical dissection. Five of six nonunions united with one procedure. There was one residual nonunion in a patient with a wide canal and an arthrodesed shoulder above the nonunion. There were three preoperative radial and two preoperative axillary nerve palsies, and no iatrogenic nerve palsies. In all patients with anterior deltoid incisions, shoulder motion returned reliably, but took as long as 6 months. Four rods were left prominent in the rotator cuff and the patients had symptoms of impingement until rod removal. Six patients had restricted shoulder function, one due to a fracture of the humeral head and five from a lateral deltoid incision. This incision was used in 12 cases. There were no stiff shoulders when using an anterior deltoid incision.     

Surgical treatment of traumatic pediatric humeral diaphyseal fractures with titanium elastic nails

Background  Nearly all pediatric humeral shaft fractures can be successfully treated with closed methods. Some patients, however, require internal fixation either because of an inability to maintain an adequate reduction, significant soft tissue injury, or concomitant fractures. Methods  This is a retrospective review of all traumatic humeral shaft fractures treated at our hospitals between 1999 and 2006. Thirteen pediatric patients ranging in age from 4.8 to 16.7 years (mean age 12.0 years) were treated surgically with titanium elastic nails (TENs). Relative surgical indications included open fractures, inability to maintain an acceptable reduction, the presence of ipsilateral forearm fractures (floating elbow), concomitant lower extremity fractures, and closed head injury. Two patients had associated radial nerve injury at presentation. Results  The patients were followed for a mean of 29 months. All fractures healed in good alignment. There were no intraoperative complications, including neurologic or vascular injury, and no patient developed an infection postoperatively. Two patients had nail migration, one of whom developed nail protrusion through the skin. One patient with preoperative radial nerve injury ultimately underwent tendon transfer to restore wrist extension. Of the 13 patients, 12 reported a full return to sports and other activities with no limitations or discomfort. Conclusions  When surgical stabilization of pediatric humeral shaft fractures is indicated, TEN fixation is effective and has a high rate of union and a low rate of complications. This technique is familiar to most orthopaedic surgeons treating pediatric fractures. Level of evidence  Level of evidence: IV (case series) This study was conducted at Washington University School of Medicine, St. Louis Shriners Hospital for Children, and St. Louis Children’s Hospital, St. Louis, Missouri, USA.     

Fixion nails for humeral fractures

Humeral fractures in the setting of multi-trauma are usually managed with internal fixation. We prospectively followed nine patients treated with an expandable nail (Fixion, DiscoTech, Medical Technologies, Herzliya, Israel), until union. Internal fixation rapidly stabilises the injured limb, and the lack of distal cross-bolting in this device markedly reduced our operative time. There were no complications in our series and there was evidence of clinical and radiological union within 6 months. We found the nail easy to use and effective in this clinical setting.     

The operative stabilization of pediatric diaphyseal femur fractures with flexible intramedullary nails

Flexible intramedullary fixation is an excellent technique for the stabilization of pediatric diaphyseal femurfractures when an indication for operative repair exists. They can be applied in an antegrade and a retrograde manner and can be used to stabilize fractures from the subtrochanteric region of the proximal femur to a point approximately 4 cm proximal to the distal femoral growth plate.

Stabilization of pediatric diaphyseal femur fractures with flexible intramedullary nails (a technique paper).

The indications for surgical stabilization of a pediatric diaphyseal femur fracture are expanding. Children with multiple system injuries, a head injury, and/or multiple fractures have fewer local and distant complications if the femur fracture is treated operatively. Other indications include a pathological fracture in osteoporotic bone, a fracture in a child with a preexisting condition that prevents the application of a spica cast, a child older than 10 years of age, or a child less than 10 years of age who cannot be kept adequately aligned using conventional (traction/casting) methods of fracture management. Here we describe a technique of stabilizing pediatric diaphyseal femur fractures using flexible intramedullary nails (Ender). This technique can be used in children of all ages and with all patterns of diaphyseal fractures.     

Medial and lateral segond fractures in a skeletally immature patient: a radiographic marker for the multiply injured knee

Marginal fractures of the medial tibial plateau have been reported in the literature as a secondary type of Segond fracture. Some reports described this entity in the setting of combined injuries such as root avulsions of the medial meniscus, complete disruption of the posterior cruciate ligament (PCL), partial tear of the anterior cruciate ligament (ACL), and tears of the medial meniscus and medial collateral ligament. It has been postulated that medial marginal fractures are secondary to compression of the medial aspect of the femoral condyle and tibial plateau with a corresponding posterolateral corner injury. However, this mechanism of injury may not always be as straightforward.This article presents a case of an alternate injury pattern in a skeletally immature patient. A 16-year-old boy sustained a varus force and twisting injury to his knee, resulting in radiographic evidence of multiple avulsion fractures of the knee, including a fibular epiphyseal avulsion fracture and medial and lateral Segond fractures. Usually, the avulsion fractures serve as markers for significant ligamentous injuries in adult patients, but our patient had minimal injury to the PCL, ACL, and posterolateral corner. Further physical examination and imaging studies revealed an anterior horn root avulsion, meniscocapsular separation, and anterior cortical rim fracture. A combination of imaging modalities helped us further characterize the injury pattern to devise the optimal surgical plan, especially the fixation of the anterior cortical fracture of the tibia.     

Early versus delayed repair of facial fractures in the multiply injured patient.

The management of facial fractures in the polytrauma patient requires the coordination of multiple surgical disciplines to optimize the functional and cosmetic outcome while minimizing overall morbidity and mortality. Although the plastic surgery literature historically advocates the early repair of facial fractures, the risk of general anesthesia in patients with associated injuries sometimes makes early repair unsafe. We compared early operative repair versus delayed operative repair of facial fractures in multitrauma patients. We specifically examined wound infection, overall complication rate, total length of hospital stay, days in the Intensive Care Unit (ICU), and days on the ventilator in the two groups. A 5-year (1991-1996) retrospective study of multitrauma patients with associated facial fractures was undertaken at an urban community hospital. We had a total of 82 patients, who were divided into three groups. Thirty-three patients did not have operative repair of the facial fractures during the initial admission and were followed by the plastic surgery service on an outpatient basis. These patients will not be discussed further. Seven patients underwent early operative repair, which was defined as repair within 48 hours of admission (group I). Forty-two patients had delayed operative repair, defined as repair more than 48 hours after admission (group II). The reasons for delayed repair included: excessive soft tissue swelling (16), intracranial injuries (12), unstable medical condition (8), and coordination of procedures with other services (6). Of the 49 patients who underwent operative repair, 43 were involved in motor vehicle accidents, 3 were injured by a fall from a height, 2 were involved in auto-pedestrian accidents, and 1 was a victim of assault. Forty-eight of the 49 patients were initially admitted to the ICU. Cumulative associated injuries were as follows: closed head injury (38), extremity fracture (21), blunt chest injuries (11), intra-abdominal injuries (5), vertebral column injuries (7), and ocular injuries (2). The average Injury Severity Score for Group I was 17.3 and for Group II, 18.1. In group I, there were no deaths, there were no wound infections, and the complication rate was 14.3 per cent. The average total number of days spent on the ventilator was 3.0, the average total number of days spent in the ICU was 5.0, and the average total hospital stay was 16.0 days. In group II, there were no deaths, the wound infection rate was 5 per cent, and the overall complication rate was 21 per cent. The average total number of days spent on the ventilator was 3.3, the average total number of days spent in the ICU was 5.8, and the average total days in the hospital was 14.8. Our results indicate that in a similar cohort of multitrauma patients, delayed repair did not increase length of ICU stay or hospital stay. The wound infection rate was negligible, and the complication rate was similar in the two groups. We conclude that a delay in repair of facial fractures in the critically ill patient has an acceptably low complication rate and may be advantageous in decreasing operative risk and minimizing cost by coordinating multiple procedures with various surgical subspecialties.     

Evaluating the multiply injured patient radiographically

In the multiply injured patient there are obvious lesions that often overshadow other lesions, creating a significant possibility that they will be overlooked. Because of the high incidence of missed lesions in such patients, it is a good idea to approach the patient with the presumption that one may be overlooking something and ask oneself what other lesions may be associated with the known lesions. We have enumerated several injuries that frequently occur together and have called them clinical dyads. It is hoped that knowledge of the associations will prevent oversight of the second lesion. The radiographic examination serves as an extension of the physical examination, confirming clinical suspicions and documenting the extent of many injuries. We have outlined what we believe is a prudent radiographic examination in a multiply injured patient. It provides information about the areas most likely to have injuries but is not so extensive that it hinders patient care. It is a starting place or survey and may lead to other, more complicated radiographic studies should the findings warrant them.     

Occult orthopaedic trauma in the multiply injured patient

A retrospective review of 111 multitrauma patients revealed that of 401 orthopaedic injuries, 24 injuries (6%) were not initially diagnosed in 20 patients. Patients with occult injuries tended to have greater overall trauma, as reflected by lower trauma and lower Glasgow coma scores and longer hospital and intensive-care unit stays. Twenty prospectively identified cases were added to the series to further define risk factors. Seventy percent of occult bony injuries were ultimately diagnosed by physical examination and plain radiographs alone. Only 27% of cases required sophisticated imaging techniques for diagnosis. Based on these 44 cases of occult injuries in multitrauma victims, the following risk factors were identified: (1) significant multisystem trauma with another more apparent orthopaedic injury within the same extremity, (2) trauma victim too unstable for full initial orthopaedic evaluation, (3) altered sensorium, (4) hastily applied emergency splint obscuring a less apparent injury, (5) poor quality or inadequate initial radiographs, and (6) inadequate significance assigned to minor signs/symptoms in a major trauma victim. Due to the nature and extent of the overall trauma, all injuries cannot be diagnosed on initial patient evaluation.     

Orange city tapping nail: An innovative implant for humeral diaphyseal fractures

BackgroundWe have conducted this study to evaluate the effectiveness of Orange City tapping nail in humeral diaphyseal fractures in terms of radiological union, shoulder function and complications. It’s a pilot study with the new implant “Orange City tapping nail” developed at our institute.Materials and methodsThirty patients with humeral diaphyseal fractures were treated with Orange City tapping nail through antegrade nailing procedure. The cases were followed up prospectively for a period of minimum six months. Outcome of the procedure were assessed according to American Shoulder and Elbow Surgeons (ASES) score, radiological union, complications and secondary procedures required.ResultsTwenty eight (93.33%) fractures united with an average consolidation time of 15.75 weeks. Two patients had nonunion. Functional outcome was excellent to good in 24 (80%) patients. One (3.33%) case had infection with Orange City tapping nail.ConclusionResults of Orange City tapping nail were excellent to good for humeral diaphyseal fractures in terms of union, shoulder function and complications. It is a safe, easy and reliable method for the treatment of humeral diaphyseal fractures. Postoperative shoulder stiffness and impingement depends on operative technique and postoperative rehabilitation. We need a larger comparative study with conventional antegrade nail to evaluate the effectiveness of the implant.

Locking plate fixation for proximal humeral fractures: initial results with a new implant

Treatment of proximal humeral fractures remains controversial, with multiple reported techniques and variable results. Recently, locking plates have become available for fixation of osteopenic and comminuted fractures. This study reports our initial experience with a new locking plate designed specifically for proximal humeral fractures. We observed 16 patients until union or revision with a mean of 12 months' follow-up. Of the 16 patients, 9 had high-energy injuries. There were nine 3-part, five 2-part, and two 4-part fractures. Twelve of sixteen patients healed without complications. There were 4 nonunions; all occurred in patients with 3-part fractures with metadiaphyseal comminution, 3 of whom were heavy smokers. In patients with united fractures, mean elevation was 132 degrees and mean external rotation was 43 degrees, with mean internal rotation to T11. Locking plate fixation achieved union in 75% of patients in this series. Risk factors for delayed union or nonunion included comminution, smoking, and 3-part fractures. These fractures remain challenging despite the availability of locked plating systems.
