Purpose: The purpose of this study is to compare the clinical and radiological outcomes of two surgical treatments, transacromial pin fixation and hook plate fixation, for unstable distal clavicle fractures. Materials and Methods: Twenty four patients with Neer type II distal clavicle fractures who underwent surgery with transacromial pin fixation (Group I: 12 patients) and hook plate fixation (Group II: 12 patients) were included. Reduction and union were evaluated using plain radiographs. Functional evaluation was performed according to UCLA score and Constant-Murley score at last follow-up. Results: All 24 cases showed bone union. Complete union took an average of 10 weeks for group I and 11.7 weeks for group II. Average UCLA score was 33 (group I) and 32.8 (group II). Average Constant score was 88.5 (group I) and 88.8 (group II). No significant difference for each variable was observed between the two groups. Conclusion: For the surgical treatment of Neer type II distal clavicle fractures, transacromial pin fixation and hook plate fixation are both useful methods.

Purpose: To evaluate the results of the compression plate fixation and autogenous bone graft in the management of humerus shaft nonunion. Materials and Methods: Eighteen cases were treated for humerus shaft nonunion using compression plate fixation and an autogenous iliac bone graft. The mean follow-up period was 28 months. Bony union was confirmed from the serial radiographs and the clinical outcomes were assessed according to ASES scoring system. Results: In 12 cases of initial plate fixation, the causes of nonunion were 6 cases of inadequate plate length, 2 with a broken plate, 2 with screw loosening, 1 infection and 1 noncompliance of a psychiatric patient. In 3 cases of initial intramedullary fixation, the cause of nonunion was a distraction of the fracture site. In 3 cases of external fixation, the cause of nonunion was inadequate fixation. All cases showed bony union after an average of 24 weeks. The clinical outcomes were 11 excellent, 6 good and 1 fair. Conclusion: In the treatment for nonunion, compression plate fixation with autogeneous bone graft after complete removal of the fibrous and necrotic tissue is believed to give satisfactory results.

Three dogs were presented with diaphyseal fracture of the tibia following separate motor vehicle accidents. On physical and orthopedic examinations, the dogs were noted to have soft-tissue swelling and a closed fracture in these tibia sites. Radiographs revealed a simple, short oblique fracture (case 1), a comminuted, spiral fracture (case 2), and a simple, spiral fracture (case 3) in tibia. Minimally invasive percutaneous plate osteosynthesis (MIPO) using a veterinary cuttable plate or locking plate was applied for the treatment of these fractures. The surgery was successful, and the fractures healed without any complications by 7 weeks (case 1), 10 weeks (case 2) and 8 weeks (case 3) after surgery. Our patients showed fast bone healing times and early weight-bearing during the treatment of their tibia fractures. Therefore, MIPO was a useful procedure for diaphyseal fracture of the tibia in veterinary orthopedics.

Purpose: To report the clinical results of two cases of coronoid process fractures that were treated with volar plating through a medial approach. Materials and Methods: Two fractures of the coronoid process that needed to be fixed were managed with open reduction and internal fixation through a medial approach using 2.4 mm locking compression plates (Compact Hand set$^{(R)}$, Synthes, Switzerland). The patients were followed up for 14 months and 17 months and were evaluated using the Mayo Elbow Performance Score (MEPS). Results: The MEPS was 95 for Case 1 and 100 for Case 2. Active elbow joint motions were $5^{\circ}-120^{\circ}$ (Case 1) and $0^{\circ}-130^{\circ}$ (Case 2). Supination and pronation fully recovered. Conclusion: Satisfactory results can be obtained in cases of coronoid process fractures because volar plating through a medial approach allows sound fixation and early mobilization of the elbow joint.

Clavicle Hook pate was commonly used in the injury around distal clavicle such as fractures, acromio-clavicular joint injury. We experienced a case of impingement syndrome following operation of distal clavicle fracture using Clavicle Hook plate. So we report this case with a reiview of current literatures.

After volar locking plating of distal radius fracture, complications arising from unrecognized dorsally prominent screws penetrating the extensor compartments are increasingly reported. However, standard radiography and fluoroscopy may not adequately visualize screw lengths, because of complex shape of dorsal cortex of the distal radius. We presented case of ultrasonography diagnosis of extensor tenosynovitis caused by dorsal screw prominence after volar plate fixation of distal radius fracture.

Purpose: To evaluate the result of operative treatment with plate and wire fixation for fractures of the distal clavicle. Materials and Methods: We assessed 9 cases of fractures of the distal clavicle that were treated by plate and wire fixation from March 2001 to July 2003 and followed up over 1year. We used the reconstruction plate as a buttress and performed cerclage wiring to fix comminuted fracture site. The functional result of shoulder was evaluated by the scoring system of Rowe. Results: The average periods of bony union was 9 weeks in all cases. According to Rowe scoring system, the functional result was exellent in 7 cases and good in 2 cases. There was no LOM of shoulder and traumatic arthritis in AC joint. But there was skin irritation in 1 case. Conclusion : The operative method by reconstruction plate and wire fixation for distal clavicular fracture was useful when there were comminuted fracture. This method seems to be simple and satisfactory in terms of improvement of range of motion of shoulder, restoration of function and rare complication.

Purpose: This study compared the functional and radiologic outcomes of intramedullary nailing (IMN) and minimally invasive plate osteosynthesis (MIPO) for tibia fractures in distal tibial spiral fractures combined with posterior malleolar fractures, as well as the functional and radiologic outcomes with and without fixation for posterior malleolar fractures. Materials and Methods: From January 2010 to December 2018 the radiological and clinical outcomes of 30 skeletally mature patients with tibial spiral fractures (AO Foundation/Orthopaedic Trauma Association classification 42-A1, B1, C1) combined with posterior malleolar fractures were analyzed. Sixteen patients were treated with IMN, and 14 patients were treated with MIPO. Depending on the surgical methods, the radiologic and clinical outcomes were compared by evaluating the bone union time, postoperative alignment, postoperative displacement of the posterior malleolar fragment, and American Orthopaedic Foot and Ankle Society (AOFAS) score. Moreover, the functional and clinical outcomes with and without fixation for posterior malleolar fractures were compared. Results: The mean bone union time was 21.8 weeks in the IMN group and 23.1 weeks in the MIPO group (p=0.500). At the final follow up, the mean alignment was coronal angulation of 1.8°, sagittal angulation of 1.6° in the IMN group and coronal angulation of 1.2° and sagittal angulation of 1.7° in the MIPO group (conoral angulation: p=0.131, sagittal angulation: p=0.850). The postoperative and final radiologic evaluation showed no displacement of the posterior malleolar fragment and excellent joint congruity in all cases. At the final follow-up, the mean AOFAS score was 88.0 on average in the IMN group and 87.6 on average in the MIPO group (p=0.905). The ankle range of motion and AOFAS score were similar in the fixation group and no fixation group for posterior malleolar fractures. Conclusion: Both IMN and MIPO for tibial spiral fractures combined with posterior malleolar fractures result in satisfactory radiological and clinical outcomes.

The treatment of a brachymetacarpia using conventional distraction osteogenesis requires holding an external fixator following distraction for stability, which causes prolonged discomfort that adversely affects the patient's daily activities. This paper reports a case of a 20-year-old male of brachymetacarpia treated with distraction osteogenesis combined with a plate reducing the period of an external fixator, allowing rapid return to the daily activities, and presenting good clinical results.
