Purpose: To evaluate the results of open reduction and internal fixation for displaced talar neck fracture. Materials and Methods: Fourteen patients were followed for more than 1 year after open reduction and internal fixation of displaced talar neck fracture. The mean age was 41.5 years, and the mean follow-up period was 3.8 years. There were 10 type II, 3 type III and 1 type IV fractures per Hawkins. There were 3 open fractures. Clinically AOFAS ankle-hindfoot scale and Hawkins criteria were utilized. Radiologically quality of reduction, duration of bony union, avascular necrosis and posttraumatic arthritis were evaluated. Results: At last follow-up, AOFAS scale was mean 89.1 points. There were 8 excellent, 4 good, and 2 fair results according to Hawkins criteria. Radiologically anatomical reduction was obtained in 13 cases. Mean duration of bony union was 11.8 weeks. There were 3 avascular necrosis and 2 post-traumatic arthritis. There was no significant difference in the incidence of avascular necrosis between early operation group and surgically delayed group. Conclusion: Accurate open reduction and rigid internal fixation seem to be prerequisites for satisfactory treatment of a displaced talar neck fracture.

We presented a case of posteriorly displaced fracture of the distal clavicle in Child. The closed reduction was failed due to posteriorly displaced proximal fragment and interpositon of trapezius muscle and periosteum. We found that periosteal sleeve and coracoclaviclar ligament and acromioclavicular ligament was intact. The open reduction should be considered for the treatment of the irreducible posteriorly displaced fracture of the distal clavicle in child.

Purpose Displaced lateral end fracture of clavicle and acromioclavicular dislocation type Ⅲ∼Ⅵ may be required surgical treatment. Material and Methods : From May 1998 to March 2001, we operated with Welter plate with minimal incision by one surgeon. Immediately, pendulum and passive exercise was initiated after surgery. The shoulder function was evaluated using UCLA score. Average follow up was on 28(12∼45) months. Results : All 11 patients were regained satisfactory function. Average UCLA score was 31.9(29~35) at last follow up. Conclusion . The merit of Welter plate fixation with minimal incision is simple technique, reduced surgical time, smaller scar than large plate, strong fixation, early exercise, reduced implant failure. The disadvantage is expensive, skin irritatatation by long hook. But Welter plate fixation with minimal incision is a good method of internal fixation and excellent clinical result in surgical treatment of type H displaced lateral end fracture of the clavicle and type Ⅲ∼Ⅵ acromioclavicular dislocation.

Purpose: The authors used arthroscopy-assisted percutaneous reduction and cannulated screw fixation rather? than conventional arthrotomy for displaced glenoid fracture. Materials and Methods: We used arthroscopy assisted reduction and screw fixation for a 66 year old man who had a clavicle fracture, a displaced glenoid fracture and a scapula fracture. Results: At 9 months postoperatively, the patient had recovered full range of motion and was not inconvenienced by the surgery. Removal of the implant was done 12 months post-operatively under general anesthesia. Conclusion: The advantages of arthroscopy-assisted percutaneous screw fixation are less pain and less bleeding, shorter hospital stay and earlier rehabilitation. Arthroscopic percutaneous screw fixation for a displaced glenoid fracture seems to be a good alternative treatment method.

Acromial fractures are well-documented complications subsequent to reverse shoulder arthroplasty (RSA), and most appear as stress fractures with no history of single trauma. To date, no study has reported the occurrence of acute displaced acromial fracture due to sudden strong deltoid contraction during heavy work. Displacement of the fracture results in a challenging surgery since it is difficult to obtain adequate fixation in thin and osteoporotic bones. We report a rare case of acute displaced acromial fracture after successful RSA treatment, using a novel technique of open reduction and internal fixation, applying two 4.5 mm cannulated screws and lateral clavicle precontoured plate.

Diagnoses of the acromial fractures are frequently delayed because most acromial fractures are non-displaced or minimally displaced patterns and the frequency are low. We report a case that a non-displaced acromial fracture of 74 years old male hit by the falling pipes could be diagnosed by the ultrasonography. For this case who had a pain, swelling, and the limitation of active elevation of the left shoulder after direct injury, the evaluation about the rotator cuff and the biceps long head tendon was required but the early diagnosis of the non-displaced acromial fracture was done by the easier ultrasonography before the additional studies. The ultrasonography has the advantage over the computed tomography in the aspect of evaluating the injury of the tendons of the shoulder joint.

Purpose: This study assessed the diagnostic performance of stitched and non-stitched cross-sectional cone-beam computed tomography (CBCT) images of non-displaced ovine mandibular fractures. Materials and Methods: In this ex vivo study, non-displaced fractures were artificially created in 10 ovine mandibles (20 hemi-mandibles) using a hammer. The control group comprised 8 hemi-mandibles. The non-displaced fracture lines were oblique or vertical, <0.5 mm wide, 10-20 mm long, and only in the buccal or lingual cortex. Fracture lines in the ramus and posterior mandible were created to be at the interface or borders of the 2 stitched images. CBCT images were obtained from the specimens with an 80 mm×80 mm field of view before and after fracture induction. OnDemand software (Cybermed, Seoul, Korea) was used for stitching the CBCT images. Four observers evaluated 56 (28 stitched and 28 non-stitched) images to detect fracture lines. The diagnostic performance of stitched and non-stitched images was assessed by calculating the area under the receiver operating characteristic curve (AUC). Sensitivity and specificity values were also calculated (alpha=0.05). Results: The AUC was calculated to be 0.862 and 0.825 for the stitched and non-stitched images, respectively (P=0.747). The sensitivity and specificity were 90% and 75% for the non-stitched images and 85% and 87% for the stitched images, respectively. The inter-observer reliability was shown by a Fleiss kappa coefficient of 0.79, indicating good agreement. Conclusion: No significant difference was found in the diagnostic performance of stitched and non-stitched cross-sectional CBCT images of non-displaced fractures of the ovine mandible.

The purpose of this study is to discuss several approaches to addressing naso-orbito-ethmoidal (NOE) fracture. Orbital fracture, especially infraorbital fracture, can be treated through the transconjunctival approach easily. However, in more severe cases, for example, fracture extending to the medial orbital wall or zygomatico-frontal suture line, only transconjunctival incision is insufficient to secure good surgical field. And, it also has risk of tearing the conjunctiva, which could injure the lacrimal duct. Also, in most complex types of facial fracture such as NOE fracture or panfacial fracture, destruction of the structure often occurs, for example, trap-door deformity; a fracture of orbital floor where the inferiorly displaced blowout facture recoils to its original position, or vertical folding deformity; fractured fragments are displaced under the other fragments, causing multiple-packed layers of bone.

Simple clavicle fractures can achieve satisfactory results through conservative treatment, and the less frequency of nonunion. Non-union or malunion can occur in displaced clavicle fractures or comminuted shaft fractures. Treatment of displaced comminuted clavicle shaft fractures is performed by holding together the free fragments with interfragmentary screws or wires and fixing them to the clavicle with a plate. Therefore, we performed interfragmentary fixation using open reduction and internal fixation with bioresorbable screws (Mg-Ca alloy, Resomet bioresorbable bone screw; U&I Corp.) and bioresorbable wires (Mg-Ca alloy, Resomet bioresorbable K-wire and pin, U&I Corp.) for displaced comminuted clavicle fractures (Robinson type 2B) and additionally used a metal plate. We expected decreased irritation and infection due to absorption after surgery. We report four cases that were treated in this way.

Recently, open reduction and internal fixation has been the treatment of choice for displaced intra-articular calcaneal fractures for many orthopaedic surgeons. However controversy still surrounds the optimal treatment with regard to whether displaced intra-articular calcaneal fractures should be treated operatively or conservatively. Conservative treatments include use of splint, rest, leg elevation, icing, use of analgesics and early mobilization. Operative treatment is open reduction and internal fixation, performed through an extensile lateral approach with interfragmentary screws and application of a neutralization plate. We reviewed the question of whether operative treatment by open reduction and internal fixation provides a benefit compared with conservative treatment for displaced intra-articular calcaneal fractures.
