A three-year-old female spayed Lurcher was referred for the treatment of a highly comminuted distal tibial articular fracture. Resection of the area of comminution with a transverse osteotomy of the tibial diaphysis and talar ridges was performed, followed by modified pantarsal arthrodesis and a calcaneotibial screw. The treatment resulted in 7 cm of tibial shortening, equating to a 28% reduction in the total tibial length. Radiographic union of the arthrodesis was successful. Fair use of the pelvic limb was documented long-term. Combined acute limb shortening and modified pantarsal arthrodesis resulted in an acceptable outcome and could be considered in cases of highly comminuted distal tibial fractures.

A dog aged two years and seven months and a cat aged seven years were referred owing to fractures of long bones. Preoperative radiographs revealed comminuted bone fractures close to joints. Conventionally, long-bone fractures are treated using intramedullary pins, plate and screw systems, or an external fixator system. In cases of non-reducible fractures, various graft materials have been used in fracture treatments to stimulate bone repair. Here, recombinant human bone morphogenetic protein-2 (rhBMP-2) and a collagen membrane were applied. Four weeks after surgery, fractured bone fragments began to unite and the bone union was observed using radiography four months after surgery. No complications occurred related to grafted materials. We successfully applied rhBMP-2 and collagen membranes in two different species to support the healing process of comminuted fractures, according to the concept of guided bone regeneration.

Purpose: For blowout fracture of the medial orbital wall, the goals of treatment are complete reduction of the herniated soft tissue and anatomic reconstruction of the wall without surgical complications. Surgeons frequently worry about damage to the optic nerve from the dissection, when the part over the posterior ethmoidal foramen was fractured. The authors performed small incision and inlay grafting for reconstruction of medial orbital wall fracture. Methods: Between January 2007 and April 2008, 15 out of 32 patients were included in an analysing the outcome of corrected medial orbital wall fracture. In 15 patients of posterior comminuted fracture of medial orbital wall, insertion of porous polyethylene($Medpor^{(R)}$ channel implant, Porex, USA) to ethmoidal sinus was performed in multiple layer, through the transconjunctival approach (inlay grafting). Results: In all cases, the orbital bone volume was reconstructed in its normal anatomical position. The associated ocular problems disappeared except for mild enophthalmos in 2 patients and there were no surgical complications associated with inlay grafting. Conclusion: The advantage of inlay grafting include anatomical reconstruction of the orbital wall; the avoidance of optic nerve injury; the simplicity of the procedure; and consequently, the absence of surgery-related complications. This technique is presented as one of the preferred treatments for posterior comminuted fracture of medial orbital wall.

The comminuted fracture and dislocation of the proximal humerus occur more frequently in older patient group and operative treatment is difficult due to poor bone quality. Based on Neer's work, hemiarthroplasty has now become widly accepted for the management of the three-part fracture and four-part fracture-dislocation of the proximal humerus in old age group. The purpose of this study is to evaluate function, pain relief, and patient satisfaction after hemiarthroplasty for proximal humerus fractures and dislocations. Authors reviewed and analyzed 14 prosthetic replacement in comminuted proximal humeral fracture and dislocation at the Department of Orthopaedic Surgery, Yonsei University Wonju College of Medicine from March, 1988 to May, 1997. The results were as follows the average age was 58.9years and the ratio of males and females was 5:9. The most common cause of injury was traffic accident(43%). According to the classification of Neer, three part fracture were three(21%), four-part fracture and four-part fracture-dislocation were eleven(79%). The prosthetic replacement was performed within two weeks in eight patient and six were performed after two weeks. The results were analysed according to Neer's criteria and five cases showed satisfactory results. We concluded that hemiarthroplasty for fracture and dislocation of the proximal humerus facilitated the restoration of humerus length and pain relief, thereby allowing earlier motion to prevent the development of painful shoulder: stiffness.

Traditional management of comminuted tibia fractures with massive bone and soft tissue defect includes soft tissue coverage and bone grafting. However, this method requires a large flap and a substantial amount of bone graft. Acute shortening can reduce the amount of required soft tissue and bone graft. We report a case of open tibia and fibula fracture with severe bone and soft tissue defect that was successfully treated by acute shortening of the tibia with immediate fibular strut bone graft and then by gradual lengthening of the tibia at its proximal metaphysis.

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.

Purpose: We present a case of anterior glenoid rim comminuted fracture that was treated with arthroscopic reduction and an AO headless compression screw (HCS) fixation. Materials and Methods: A 31-year old man complained of left shoulder pain after falling down on stairs. The anterior glenoid comminuted fragments were arthroscopically reduced. Fixation with an AO HCS was done after placement of 1.1 mm Kirschner wire as a guide pin through a standard cannulated anterosuperior portal. Results: Twelve months after the operation, union of the fracture was achieved and the range of motion was fully recovered. He did not complain of any discomfort during his activities of daily living. Conclusion: An AO HCS had various screw sizes and this was good for fixation of a small glenoid fracture and a long drill bit and screw driver were useful for fixation of deep seated glenoid fracture. A short guide wire could be replaced by a 1.1 mm K-wire. An AO HCS was useful for fixation of an anterior glenoid rim comminuted fracture.

Purpose : The aim of this study is the assessment of the clinical outcomes after percutanous pinning of unstable two-parts fracture of surgical neck in humerus. Materials and Methods: This study was based on thirteen cases of non-comminuted unstable surgical neck fracture of humerus among 19 cases, which followed-up more than one year. Follow-up averaged 29 months. We treated with percutaneous pinning techniques and assessed clinical outcomes. Functional evaluation was performed using the standard method of research committee of American Shoulder and Elbow Surgeons(ASES). Results: Last follow-up ROM of shoulder joint were 142 degrees of forward elevation, 57 degrees of external rotation, 72 degrees of external rotation in 90 degrees abduction, and T8 of internal rotation. Pain scale was l(range : 0∼3). ASES scores was 86.2(range : 63.3~98.3). Patient satisfaction based on ASES were excellent in 6 cases, good in 5 cases, fair in 1 case, poor in 1 case. A case of fair result was caused by limitation of motion in shoulder joint and poor case was paraplegia patient after traffic accident. Conclusion : Percutaneous pinning is recommended for non-comminuted unstable fracture of surgical neck in humerus.

Purpose : To evaluate functional results and study factors influencing results after humeral hemiarthroplasty for comminuted fractures of the proximal humerus. Materials and Methods: We reviewed 12 patients with average follow-up period of 23 months(12 to 42). The proximal humeral fractures consisted of one anatomical neck fracture, five three-part and six four-part fractures or fracture-dislocations. Constant score and Compito et al' evaluation system were used for clinical assessment. Statistical analysis was done with the Wilcoxon test. Results: Six cases of anatomical neck, three-part fractures or fracture-dislocations showed 61 points on the average Constant score and three unsatisfactory results on the Compito et al' evaluation; Six of four-part fractures or fracture-dislocations showed 51 points and three unsatisfactory results. There were 59(two unsatisfactory) for five non-associated dislocation and 53(four unsatistactory) for seven associated dislocation; 66(one unsatisfactory) for three under 60 years and 41(five unsatisfactory) for nine over 60 years; 67(two unsatisfactory) for seven tuberosity union and 41(four unsatisfactory) for five tuberosity non-union or resorption; 58(four unsatisfactory) for ten early operation within two weeks and 43(all unsatisfactory) for two delayed operation; and 18(unsatisfactory) for one case of a accompanied rotator cuff tear. Conclusion: We concluded that tuberosity union was important factor influencing the results. Also, we thought that age, timing of operation and accompanied rotator cuff tear could be influenced to results.
