PHILOS plate fixation in osteoporotic proximal humerus fracture of old age is well-known for high complication rate, especially metal failure, providing various augmentation techniques, such as calcium phosphate cement, allogenous or autologous bone graft. We report a case of polymethyl methacrylate augmentation to provide appropriate reduction with a significant mechanical support. This can be a treatment option for displaced unstable osteoporotic proximal humerus fracture with marked bony defect.

Complex cervical spine fractures are a serious complications of maxillofacial trauma and associated with high mortality and neurological morbidity. Strict vigilance in preventing further insult to the cervical spine is a crucial step in managing patients who are at risk for neurologic compromise. We report a rare case of a right transverse process of atlas fracture with right-sided vertebral artery injury that was associated with a comminuted fracture of the body and angle of the mandible, which restricted mouth opening. Airway management was performed by an awake fiber-optic nasotracheal intubation, where neck movement was avoided with a cervical collar. Vertebral artery injuries may have disastrous consequences, such as basilar territory infarction and death, and should be suspected in patients with head and neck trauma. After mandibular plating, the patient was on cervical collar immobilization for 12 weeks and anti-coagulant therapy.

Fractures of the clavicles are extremely common, accounting for 5 to 10% of all injuries in the adult skeletal trauma. Despite this, nonunions and symptomatic malunions after clavicular fracture are uncommon. When these complications occur, however, they may be associated with 11 pattern of disability that includes not only pain but also impairment of upper extremity function. The purpose of this study was to clarify the outcome of clavicular fractures treated by conservatively, and emphasize treatment and factors that possibly predispose a clavicular fracture to poor function or nonunion. We evaluated 9] consecutive fractures of the middle-third of the clavicle in adults which had been treated conservatively. There were 59 males and 33 females ranging in age from 17 to 80 years (average 36.8 years). Nine of the 91 fractures (10%) had developed nonunion, and 4 fractures (4.4%) reported unsatisfactory results. No patients had significant impairment of range of motion or strength as a result of the injury. We found that initial shortening at the fracture of≥20mm(6 cases) had a highly significantly association with nonunion(P<0.0001). Final shortening of 20mm or more (4 cases) was associated with an unsatisfactory result, but not with nonunion(P<0.0001). Our results have led us to recommend the open reduction and internal fixation of severely displaced fractures of the middle third of the clavicle in adults patients.

Purpose: We evaluated the clinical results of the intraarticular calcaneal fractures treated using Ollier approach by inexperienced orthopaedic surgeon. Materials and Methods: Between August 2003 and May 2007, Of the total 46 cases, 12 cases (9 patients) of displaced intraarticular calcaneal fracture who underwent open reduction and internal fixation using Ollier approach were evaluated. The means of age was 50.5 years. According to the Sanders classification, there was no type I case and 8 cases of type II, 1 case of type III, and 3 cases of type IV. We evaluated the treatment result by assessing radiologic parameters ($B{\ddot{o}}hler$ angle, Gissane angle, and calcaneal height/width) and clinical outcomes (VAS and AOFAS score). Results: The means of follow-up period was 25.3 months. The means of B.hler angle was improved from $2.4^{\circ}$ to $26.1^{\circ}$. Radiologic and clinical union was achieved in all cases without additional procedures. Excellent result were noted in 2 cases, good in 5 cases, fair in 4 cases, and poor in 1 case. We experienced 2 cases of minor complications; 1 case of mild wound infection and 1 case of hypoesthesia on foot dorsum. Radiologic findings of subtalar arthritis were present in 2 cases. Conclusion: Ollier approach seems to be helpful to inexperienced orthopaedic surgeons for the treatment of intraarticular calcaneal fractures in that it enables them to achieve considerable clinical outcomes without serious complications.

A 4-year-old male Yorkshire terrier was referred to us with signs of vomiting and unconsciousness due to a blunt head trauma. Gross examinations detected facial edema, subcutaneous hemorrhage and hypersalivation. A survey radiograph located an occipital fragment which was displaced caudally. A three-dimensional computed tomographic reconstruction demonstrated that the ventral portion of the fragment was attached incompletely. Because of the instability of the fragment, it was decided to perform an esquillectomy. After removing the fragment, the defect was reinforced with a muscular flap originating from the splenius muscle. The patient's condition gradually improved except for a slightly ataxic gait. At 20 months follow-up, there was no evidence of ataxia. The neurological status did not deteriorate before starting surgical intervention, although the patient sustained a skull fracture with severe intracranial hemorrhage. It is likely that the fragment being displaced outwardly played an important role in preventing an increase in intracranial pressure which could have led to neurological deterioration.

Purpose: This study examined the methods for treatment of femoral neck fracture (FNF) preferred by members of the Korean Hip Society (KHS) and identified factors that influence decisions regarding the surgical intervention of choice. Materials and Methods: A total of 97 members of the KHS responded to the 16-question survey which included questions about the mean number of surgeries performed each month for treatment of femoral neck fractures, the cut-off age for deciding between internal fixation and arthroplasty, the implant used most often, usage of cement, and factors influencing each decision. Results: The mean cut-off age used when deciding between internal fixation and arthroplasty was 64 years old. Hemiarthroplasty (HA) (70%) was the most preferred option for treatment of displaced FNFs in cases where arthroplasty was indicated (total hip arthroplasty [THA] 19% and dual mobility THA 11%). The main reasons for selection of arthroplasty over reduction with internal fixation were age and pre-fracture ambulatory status. Pre-trauma ambulatory status and/or sports activity were the main factors in selection of HA over THA. Cement was used by 33% of responders. Poor bone quality and a broad femoral canal were factors that influenced the usage of cement. Conclusion: Management of FNFs in the elderly is a major health problem worldwide; thus, remaining alert to current trends in treatment is essential for surgeons. The mean cut-off age used in deciding between internal fixation and arthroplasty was 64 years old. HA is the preferred method for treatment of displaced FNFs for members of the KHS.

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: It is relatively unusual that infraorbital rim fracture is accompanied by nasal bone fracture. In order to correct effectively, subciliary approach and intranasal manipulation are applied simultaneously. But if reduction is not successful, intranasal manipulation may become aggressive and this often causes complications. We introduce a method using intermaxillary fixation screws for decreasing such complications and effective reduction of fracture. Methods: Total seven patients with fracture of frontal process of maxilla were treated with this method. The fracture site was exposed through the subciliary approach, and one or two screws were inserted into the displaced fracture fragment. During the traction of the screws using the wire, the fracture fragment was pushed upward from the intranasal side using an elevator supplementarily and fixed with a plate and the screws. Results: In all patients, the fracture fragment was reduced successfully and no complication occurred during one year's postoperative follow-up. Conclusion: When reduction cannot be attained through a bone hook or an elevator alone, reduction of fracture fragment can be done easily using intermaxillary fixation screws. This method is less likely to cause a mucosal injury because intranasal manipulation is not aggressive. Furthermore, as the screw can be inserted and removed easily, this method is considered effective not only for fracture of frontal process of maxilla but also for fractures in other regions.

Purpose: Bone grafting is often necessary to maintain a reduction and prevent delayed collapse of reduced fracture in a treatment of severely displaced comminuted intra-articular calcaneal fractures. Herein, we analyzed the usefulness and necessary conditions to perform tricortical-allobone grafting in open reduction of calcaneal fracture via the Ollier approach. Materials and Methods: We performed a retrospective review of 57 intra-articular calcaneal fractures that underwent an operation via the Ollier approach between April 2009 and April 2015. They were divided into two groups: Group 1 (n=17) included those with tricortical-allobone grafts underneath the posterior facet fragment, and group 2 (n=40) included cases without a bone graft. We measured the $B{\ddot{o}}hler$ angle, Gissane angle, height, and width of the calcaneus at preoperative, postoperative, and final follow-up radiograph. We measured the sagittal rotational angle of the posterior facet fragment of preoperative computed tomography to analyze the effect and necessary conditions for bone grafting. We also reviewed the clinical results by the American Orthopaedic Foot and Ankle Society (AOFAS) scale, visual analogue scale (VAS), and any complications. Results: According to the Sanders classification, there were 3 type-II fractures, 12 type-III fractures, and 2 type-IV fractures in Group 1; whereas in Group 2, there were 26 type-II fractures, 13 type-III fractures, and 1 type-IV fracture (p=0.002). Regarding the preoperative radiologic parameters, there were significant differences in the $B{\ddot{o}}hler$ angle (p=0.006), Gissane angle (p=0.043), and rotational angle of the posterior facet fragment (p=0.001). No significant difference was observed in the preoperative calcaneal height and width, as well as postoperative radiologic parameters. There was no significant clinical difference between the two groups (p=0.546). Conclusion: We suggest that a tricortical-allobone graft may be useful in open reduction and screw fixation via the Ollier approach for displaced intra-articular calcaneal fracture with a bony defect after reduction of collapsed posterior facet fragment. This graft can contribute to the stable reduction via a small approach, even without a plate.

Twenty-three patients with chronic shoulder pain beyond 6 months after the fracture of the greater tuberosity underwent arthroscopic treatment and were retrospectively assessed after an average of 29 months(range, 22 to 40 months). There were 18 men and 5 women with the average age of 39 years(range, 24 to 61 years). Fourteen were isolated fractures and nine were related to acute anterior instability episode. The average displacement of the fracture was 2.3mm(range, 0 to 4mm) on the anteroposterior view of the plane radiographs. At the time of arthroscopy, all patients had partial thickness rotator cuff tears in the articular surface. The cuff tears were located on the tuberosity fracture area and were an Ellman's grade I to n in depth. With the arthroscopic debridement or repair of the tear depending on the condition of the tear itself, as well as the subacromial decompression, the UCLA score revealed good to excellent results in 20 and fair in 3 patients. Nineteen of the patients had returned to the previous level of activities. The patient with a higher activity demand revealed a lower level of activity return(p=0.034). The partial thickness rotator cuff tear should be considered in patients with chronic shoulder pain after the minimally displaced fracture of the greater tuberosity, and arthroscopic debridement or repair is an appropriate procedure.
