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.

Purpose: The purpose of this study is to analyze the clinical features of distal tibia fractures and to evaluate the treatment outcomes of minimally invasive plate osteosynthesis (MIPO). Materials and Methods: From January 2004 to December 2009, 84 cases of 81 patients treated with plate fixation for distal tibia fracture were enrolled in this retrospective review. We investigated age, sex, injury mechanism, fracture patterns, and complications, and the clinical features were analyzed. To evaluate the treatment outcomes of MIPO, we divided into two groups. MIPO group consisted of 55 patients were treated with MIPO technique and conventional group consisted of 18 patients were treated with open reduction and internal fixation with conventional anterolateral plating. The results were compared between two groups by assessing bony union time, operation time, amount of blood loss, range of ankle motion, clinical score by American Orthopaedic Foot and Ankle Society (AOFAS) score, and post-operative complications. Results: The mean age of 81 patients with distal tibia fracture was 54.8 years. According to AO classification, A1:2:3 were 16, 20, 16 patients, B1:2:3 were 2, 8, 7, C1:2:3 were 1, 3, 11 patients. According to injury mechanism, slip down injury was patients, traffic accident was 26, fall from height injury was 14 patients respectively. The type A fractures were lower energy trauma and more older patients. The type C fractures were higher energy trauma and younger patients. MIPO group was better than conventional group in operative time, blood loss, bony union time, and ankle joint motion. In complications, MIPO group showed no nonunion and infection, one malunion, one skin necrosis, nine skin irritations, and one screw breakage. Conventional group showed two nonunion, four infections, two skin necrosis, and one metal failure. Conclusion: Distal tibial fractures caused by low energy trauma were on the increase. Minimal invasive plate osteosynthesis was shorter bony union time and operation time, less blood loss, and larger ankle motions than conventional open reduction and plate fixation.

Background: The purpose of this study is to compare clinical and radiological outcomes between trans-acromial fixation with Kirschner's wire (K-wire) and AO locking hook plate fixation for acute acromioclavicular (AC) joint dislocation. Methods: This study included 61 patients who underwent either closed reduction and trans-acromial fixation with K-wire (group A, 23 patients) or open reduction and internal fixation with AO locking hook plate (group B, 38 patients). Pain on a visual analogue scale (VAS) score, the University of California Los Angeles (UCLA) shoulder score, the American Shoulder and Elbow Surgeons (ASES) score, and active range of motion (ROM) were used in the functional evaluation. For radiological evaluation, coracoclavicular distance (CCD) was measured on both clavicular anteroposterior view and compared between groups. Results: At one-year follow-up, no significant differences in VAS pain score, UCLA shoulder score, ASES score, and active ROM were observed between groups, despite five cases (22.7%, 5/23) of complication in group A. The side-to-side difference between normal and affected CCD was $2.4{\pm}2.2mm$ in group A and $0.2{\pm}0.7mm$ in group B. This difference showed a statistical significance between groups (p<0.001). Conclusions: For the treatment of acute AC joint dislocation, the K-wire trans-acromial fixation group showed a significantly greater CCD than the AO locking hook plate group. In addition, during the follow-up period, much higher incidence of complication related to implant was observed in the trans-acromial fixation group. Although clinical outcomes between groups were not significantly different, these results should be interpreted carefully.

This study evaluated the short-term outcome of treating fractures of the mandible with bioabsorbable plates. Thirty-four fractures of the mandible in 27 patients were treated by open reduction and internal fixation using bioabsorbable plates and 2.4-mm, 2.0-mm, and 1.5-mm pre-tapped screws. The duration of intermaxillary fixation ranged from 0 to 23 days, with a mean of 5.3 days. Patients were evaluated for complications during the follow-up period, which ranged from 2 to 18 months. Five patients(18.5%) experienced complications. These included infection (four patients), and premature occlusal contact(one patient). Except for one case, all complications were minor and adequately managed with incision and drainage, elastic traction, and medication. Delayed infection (osteomyelitis) developed in a symphysis fracture and was treated by saucerization and antibiotics. The fracture line subsequently showed complete consolidation. Bioabsorbable plates can be selectively used for internal fixation in mandibular fractures with the advantage that they do not need to be removed.

Purpose: Metacarpal fractures are common hand injury that may require operative intervention to ensure adequate reduction and stabilization. Traditionally, titanium miniplate was used for rigid fixation of bone fractures. However, the use of permanent plate lends itself to multiple complications such as infection, exposure of the hardware, tendon adhesions, tendon rupture, prolonged pain, bony atrophy and osteoporosis (stress shielding), metal sensitization, and palpation under the skin. This study evaluated the usefulness and stability of biodegradable plates and screws for treatment of metacarpal bone fractures. Methods: There was 17 patients who had surgery for metacarpal bone fracture from April 2007 to June 2010. All patients had open reduction and internal fixation. We used absorbable plates and screws (Inion CPS$^{(R)}$) for internal fixation. Postoperative results were assessed with x-ray. Stability of plates and screws, healing process and its complications were observed by clinical and radiographic assessment. Results: All patients were successfully reduced of bone fracture, and fixations with absorbable plates and screws were stable. The mean follow up period was 7.1 months. 2 patients complained postoperative pain, but they were relieved with analgesics. All patients experienced transient stiffness, but they were relieved with active assistive range of motion after removal of splint. No patients suffered complications which could be occurred by using metallic plate. Conclusion: There was no critical complications such as re-fracture or nonunion among patients. No patients suffered side effects related with metallic implants. Biodegradable implants can offer clinically stable and attractive alternative to metallic implants to stabilize metacarpal bone fractures in the hand.

Purpose: To analyze the clinical and radiological results of operative treatment in patients with tongue type intra-articular calcaneal fracture, and to compare the open reduction and Essex-Lopresti technique. Materials and Methods: We examined a consecutive series of 42 patients who received surgical treatment for tongue type calcaneal fracture (24 cases of the open reduction and 18 cases of the Essex-Lopresti technique) and the postoperative data was compared with a minimum 1 year follow-up. The clinical outcome was analyzed using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scale and Salama's criteria. The preoperative, postoperative, and last follow-up changes in the Bohler angle was radiologically analyzed. Results: There were no significant differences between the two groups in terms of the clinical and radiological results at the last follow-up. However, for the Sander's type 3 and 4 fractures, the open reduction group showed more improvement of AOFAS score and less reduction loss in the Bohler angle. Conclusion: Although the clinical results were good irrespective of surgical technique, the open reduction and internal fixation can improve clinical outcome and reduce the reduction loss as compared with the Essex-Lopresti technique in the comminuted tongue type calcaneal fracture.

Purpose: Anatomical reduction of the fractured condylar process is an important prerequisite for re-establishing function. The authors reported about effectiveness of transoral approach for mandibular subcondyle fracture using trochar device in cases that the fracture line is below the reference line, the perpendicular line of the longitudinal axis of condylar process passing the lowest point of sigmoid notch. As a serial study, we report the open reduction via preauricular approach for mandibular condyle fracture, in cases that the fracture line is above the reference line. Patients and Methods: Sixteen condylar fractures of 15 adult patients were divided two groups and treated by open reduction via preauricular approach (8 cases) or by closed reduction (8 cases). The degree of maximal mouth opening, occlusion, anatomical reduction, condylar resorption and complications were assessed and evaluated for the two groups. Results: The open reduction of condyle via preauricular approach leads to good results without permanent complications. Anatomical reduction of open reduction group and maximal mouth opening range of the closed reduction group is significantly better than the other group. No significant differences were found in the condylar resorption and the occlusion. Conclusion: The preauricular approach was useful to reduce and fix the condylar fragment, in cases that the fracture line is above the reference line.

Femoral head fractures with associated hip dislocations substantially impact the functional prognosis of the hip joint and present a surgical challenge. The surgeon must select a safe approach that enables osteosynthesis of the fracture while also preserving the vascularization of the femoral head. The optimal surgical approach for these injuries remains a topic of debate. A 44-year-old woman was involved in a road traffic accident, which resulted in a posterior iliac dislocation of the hip associated with a Pipkin type II fracture of the femoral head. Given the size of the detached fragment and the risk of incarceration preventing reduction, we opted against attempting external orthopedic reduction maneuvers. Instead, we chose to perform open reduction and internal fixation using the Watson-Jones anterolateral approach. This involved navigating between the retracted tensor fascia lata muscle, positioned medially, and the gluteus medius and minimus muscles, situated laterally. During radiological and clinical follow-up visits extending to postoperative month 15, the patient showed no signs of avascular necrosis of the femoral head, progression toward coxarthrosis, or heterotopic ossification. The Watson-Jones anterolateral approach is a straightforward intermuscular and internervous surgical procedure. This method provides excellent exposure of the femoral head, preserves its primary vascularization, allows for anterior dislocation, and facilitates the anatomical reduction and fixation of the fracture.

The midtarsal joint is composed of the talonavicular and calcaneocuboid joints. It is also known as the Chopart joint. Midtarsal joint fracture and dislocation are relatively rare and frequently missed or misdiagnosed. A proper understanding about the anatomy of the midtarsal joint is an essential part in comprehending the mechanism of injury and rationale for treatment. Anatomical reduction of midtarsal joint with correction of the column in length and shape are important; however, it is technically challenging and may require open procedure. Herein, we described a case of initial open reduction and internal fixation for midtarsal joint fracture and dislocation with a brief literature review.
