Purpose: This study was designed to investigate the usefulness of extensile lateral approach for accurate reduction and rigid internal fixation in comminuted intraarticular fractures of calcaneus. Materials and Methods: From October 2002 to May 2007, we managed 55 patients (62 cases) with open reduction and internal fixation using extensile lateral approach. Among these, 38 patients (43 cases) who underwent preoperative and postoperative CT scan were enrolled. All patients were evaluated over 24 months after surgery. Bohler angle and Gissane angle on plain X-ray, displacement and step-off of articular surface of calcaneus on CT scan were measured and we compared the difference between preoperative and postoperative value of them. Clinical results were assessed by using AOFAS Ankle-Hindfoot Scale. Results: The average Bohler angle was restored from $6.8^{\circ}$ to $23.5^{\circ}$ and Gissane angle was improved from $116.4^{\circ}$ to $113.5^{\circ}$ after operation. The average distance of displacement was restored from 4.2 mm to 1.4 mm and step-off of articular surface was recovered from 5.1 mm to 1.3 mm. Clinical results were excellent in 17 cases, good in 18 cases, fair in 3 cases, and poor in 5 cases. 10 cases developed postoperative complications such as skin necrosis, heel pain, limitation of motion of ankle and subtalar arthritis. Conclusion: The extensile lateral approach is valuable for the comminuted intraarticular fractures of calcaneus that enables accurate anatomical reduction and rigid internal fixation by providing direct exposure of subtalar joint.

Since the olecranon fractures are caused by relatively low-energy injuries, such as a fall from standing height, they are usually found without comminution. Less commonly they can be developed by high-energy injuries and have severe concomitant comminution or injuries to surrounding structures of the elbow. Because the fracture by nature is intra-articular with the exception of some avulsion-type fracture, a majority of olecranon fractures are usually indicated for surgical treatment. Even if there is minimal displacement, surgical treatment is recommended because there is a possibility of further displacement by the traction force of triceps tendon. The most common type of olecranon fracture is displaced, simple non-comminuted fracture (that is, Mayo type IIA fractures). Although tension band wiring was the most widespread treatment method for these fractures previously, there is some trends toward fixation using locking plates. Primary goal of the surgery is to restore a congruent joint and extensor mechanisms by accurate reduction and stable fixation so that range of motion exercises can be performed. The literature has shown that good clinical outcomes are achieved irrespective of surgical fixation technique. However, since the soft tissue envelope around the elbow is poor and the implants are located at the subcutaneous layer, implant irritation is still the most common complication associated with surgical treatment.

Purpose: The coronal approach for repair of frontal sinus fractures is associated with significant adverse sequelae including a long scar, alopecia, paresthesias, and, uncommonly, facial nerve injury. To minimize these complications, an endoscopic approach for repair of frontal sinus fractures was developed. The authors now present the results of an endoscopy-assisted approach for the treatment of frontal sinus fractures. Methods: From 2002 to 2009, five patients with frontal sinus fracture underwent endoscopic repair. Two slit incisions were placed in the scalp, and one or two stab incisions directly over the fractures were placed in the forehead. After subperiosteal dissection, fracture segments were reduced under direct vision and fixed with microplates or fibrin glue. Results: All patients had good cosmetic results and remained free of sinus complaints. There were no perioperative complications reported. Conclusion: Endoscopic repair of frontal sinus fractures is an efficacious technique that significantly reduces patient morbidity. A relatively wide range of anterior table fractures can be reduced using an endoscope. In cases of complicated comminuted fractures, fibrin glue helps to achieve satisfactory endoscopic reduction. Endoscopic repair is an alternative treatment for various anterior table fractures of the frontal sinus.

Medical records from the Veterinary Medical Teaching Hospital of the University of Missouri-Columbia from 2004 to 2007 were available for 28 raptors that underwent long bone fracture repair. There were 14 owls, 10 hawks, 2 vultures, 1 eagle, and 1 falcon. Mean body weight was 780 g (ranged from 150 to 1400 g) for 14 owls; 650 g (ranged from 150 to 1270 g) for 10 hawks; 1760 g (ranged from 1520 to 2000 g) for 2 vultures; 5000 g for 1 eagle; and 130 g for 1 falcon. Of all 28 fracture cases, 11 cases (39%) and 1 case (3%) were related to hit-by-car and shooting respectively. Physical examination revealed dehydration in 18 raptors (64%) and lethargy in 12 raptors (42%). Forty one long bone fractures were included in 28 cases. The radiographs revealed 13 ulnar fractures (32%), 12 humeral fractures (30%), 10 radial fractures (25%), 4 tibiotarsal fractures (9%), 1 femoral fracture (2%), and 1 fibular fracture (2%). External skeletal fixation using polymethylmethacrylate (PMMA) combined with intramedullary fixation was used in 19 long bone fractures (46%). Intramedullary fixation using intramedullary Kirschner pin was used in 16 long bone fractures (39%). No surgical treatment was performed in 6 long bone fractures (15%). This study reported that many of raptors presented dehydration and lethargy when admitted for treatment. Therefore, proper hydration and nutrition are critical pre-surgical requirements. In addition, combination of internal fixation and external skeletal fixation using PMMA might be better option to treat raptors with comminuted fracture that results from mostly trauma of hit-by-car.

Objective : The classic and accepted surgical method of compound comminuted depressed skull fractures (FCCD) involves total resection of all the contaminated bone and fragments at the fracture site. A second operation for cranioplasty is then performed at a later date. However, we have believed that primary repair of these bony defects can be achieved by the replacement of bone fragments at the time of the initial debridement, and this can be accomplished without danger to patient. The authors retrospectively reviewed the surgical results to assess the advantages and disadvantages, and also propose the selection criteria of replacement of fractured bone fragments as a primary procedure in FCCD. Materials and Methods : The authors analyzed the data extracted from medical records, and radiological findings in 22 of 71 patients with FCCD, who underwent immediate replacement of fractured bone fragments between April 1993 and October 1998. The mean follow-up period was 13.7 months. The selection criteria for the operation included the patients with mild to moderate severity, regardless of the degree of contamination or dural violation, which presented in hospital within 24 hours of injury. Results : The ages of the patients varied from 4 to 63 years, and there were 20 males and 2 females. Seventeen of 22 patients were fully conscious on admission and the others also had relatively good Glasgow coma scales. Sixteen fractures were located in the frontal area, 9 with involvement of the frontal sinuses, and 6 in the parietal and temporoparietal areas. Of the 22 patients, 8(36.3%) had dural lacerations with 3 of these requiring patching with pericranium, and 12(54.5%) had intracranial hematoma requiring wide craniotomy. The degree of wound contamination was also variable. Fifteen patients had relatively clean wounds, while seven(31.8%) had seriously contaminated wounds with soil, sand, hair, and wood. Only one patient(4.5%) developed infection, and the bone fragments were removed. All wounds healed primarily without pulsatile defect, the skull has remained solid, and no complications have occurred, except the infected case. Conclusion : It is proposed that bone fragments removal for FCCD, regardless of the degree of contamination or dural violation, is not necessary and that primary bone fragments replacement avoids a second operation for cranioplasty.

After dual plating with a locking compression plate for comminuted intraarticular fractures of the distal humerus, the incidence of ulnar nerve injury after surgery has been reported to be up to 38%. This can be reduced by an anterior transposition of the ulnar nerve but some surgeons believe that extensive handling of the nerve with transposition can increase the risk of an ulnar nerve dysfunction. This paper reports ulnar nerve injuries caused by the incomplete insertion of a screw head in dual plating without an anterior ulnar nerve transposition for AO/OTA type C2 distal humerus fractures. When an anatomical locking plate is applied to a distal humeral fracture, locking screws around the ulnar nerve should be inserted fully without protrusion of the screw because an incompletely inserted screw can cause irritation or injury to the ulnar nerve because the screw head in the locking system usually has a slightly sharp edge because screw head has threads. If the change in insertion angle and resulting protruded head of the screw are unavoidable for firm fixation of fracture, the anterior transposition of the ulnar nerve is recommended over a soft tissue shield.

Purpose: The purpose of this study is to evaluate the influence of intracapsular fracture lines of the mandibular condyle on the anatomical and functional recovery after non-surgical closed treatment. Methods: Clinical and radiological follow-up of 124 patients with intracapsular fractures of the mandibular condyle was performed after closed treatment between 2005 and 2012. The intracapsular fractures were classified into three categories: type A (medial condylar pole fracture), type B (lateral condylar pole fracture with loss of vertical height) and type M (multiple fragments or comminuted fracture). Results: By radiological finding, fracture types B and M lost up to 24% vertical height of the mandibular condyle compared to the height on the opposite side. In Type M, moderate to severe dysfunction was observed in 33% of the cases. Bilateral fractures were significantly associated with the risk of temporomandibular joint (TMJ) dysfunction in fracture types A and B. Bilateral fracture and TMJ dysfunction were not statistically significantly associated in type M fractures. Conclusion: Most of the mandibular intracapsular condylar fractures recovered acceptably after conservative non-surgical treatment with functional rehabilitation, even with some anatomical shortening of the condylar height. The poor functional recovery encountered in type M fractures, especially in cases with additional fracture sites and bilateral fractures, points up the limitation of closed treatment in such cases.

Background: Many authors have evaluated the post-reduction result of nasal bone fracture through patient satisfaction or postoperative complications. However, these results are limited because they are subjective. The aim of this study was to correlate an objective operation result with patient satisfaction and postoperative complications according to the type of nasal bone fractures. Methods: Our study included 313 patients who had isolated nasal bone fractures and had undergone a closed reduction. Postoperative outcomes were evaluated objectively using computed tomographic (CT) images, while patient satisfaction was evaluated one month after the operation. The correlation of the operation result with patient satisfaction was then evaluated. Results: The correlation between the operation result and patient satisfaction was highest for the lateral impact group type I (LI) type of fracture and lowest for the comminuted fracture group (C) type of fracture. However, there were no statistically significant differences in correlation between the overall result and patient satisfaction by fracture type. The complication rate of lateral impact group type II (LII), C, and frontal impact group type I (FI) fractures were statistically significantly higher than that of frontal impact group type II (FII) and LI fractures. There were no statistically significant relationships between the prevalence of complications and septal fracture or deviation according to the fracture type. In the total group, however, there was a statistically significant difference in complication rate by septal fracture. Conclusion: We found that the CT outcomes correlated with patient satisfaction. The complication rate of LII, C, and FI fractures were statistically significantly higher than that of FII and LI fractures. Septal fracture/deviation increased the postoperative complication in the total group.

Background: Closed reduction of the fracture under general or local anesthesia with elevators or forceps is widely used to treat nasal bone fractures. However, operating under general anesthesia increases the risk of morbidity and raises the cost of management. Furthermore, using forceps or elevators may cause undercorrection, new fractures, mucosal damage, and nasal hemorrhage. We therefore performed manual reduction under local anesthesia, using the little finger, to minimize the demerits of treatment under general anesthesia with forceps or elevators and aimed to assess functional and aesthetic outcomes, and patient satisfaction. Methods: Patients who visited the plastic and reconstructive surgery department between November 2016 and November 2017 with nasal bone fractures and treated by a single surgeon were prospectively followed up. Patients with simple unilateral or bilateral nasal bone fractures were treated with bedside finger reduction under local anesthesia and patients with comminuted nasal bone or septal fractures were scheduled for closed reduction under general anesthesia. Results: Of 84 patients, 28 met the inclusion criterion and underwent bedside finger reduction under local anesthesia. Twenty-seven patients (96.4%) were successfully contacted via telephone for survey. Twenty-three (85.2%) showed good and three (11.1%) showed fair results. All 27 patients (100%) were satisfied with their postoperative function and 25 (92.6%) were satisfied with their postoperative aesthetic result. Twenty-five patients (92.6%) preferred the finger reduction method under local anesthesia over closed reduction under general anesthesia. Conclusion: Finger reduction under local anesthesia in patients with mild unilateral or bilateral nasal bone fractures is an easy and efficient procedure with high patient satisfaction and favorable postoperative functional and aesthetic outcomes.
