Comparative Evaluation of the Efficacy of Combined Intramedullary Pinning with K-Wires Pinning in the Treatment of Fifth Metacarpal Neck Fractures versus Conventional Techniques-K-Wires Pinning and Intramedullary Pinning.

: Since the neck is the weakest part of the metacarpals, the most common metacarpal fracture is a neck fracture, a type which accounts for 38% of all hand fractures. Such fractures can be fixed using a variety of conventional techniques, including intramedullary pinning and K-wire pinning. However, conventional techniques involve complications, such as angulation, stiffness, and rotational deformity.

The Inlay Technique with Cortico-Cancellous Olecranon Bone Graft Used for Revision of Failed Distal Interphalangeal Joint Arthrodesis.

: Although distal interphalangeal (DIP) arthrodesis is an effective surgical method for end-stage osteoarthritis of the phalangeal joint, the nonunion rate of DIP arthrodesis has been reported to range from 15% to 20%. To this end, we devised an inlay technique with a cortico-cancellous olecranon bone graft for failed DIP arthrodesis. This study aimed to introduce the inlay bone grafting technique for failed arthrodesis of the DIP joint and demonstrate its advantages.

Outcomes of U-Blade Lag Screw for Cephalomedullary Fixation of Unstable Trochanteric Femur Fractures: A Case Control Study.

Background: Unstable trochanteric femur fractures in elderly patients with osteoporosis are still challenging. Gamma3 nail with the U-blade lag screw (U-blade gamma nail) has been developed to improve mechanical stability of proximal femoral fragment. This study aimed to compare the clinical and radiologic outcomes of U-blade gamma nail to proximal femoral nail antirotation (PFNA), and standard Gamma3 nail (gamma nail) for unstable trochanteric femur fractures.

Minimally Invasive Plate Osteosynthesis (MIPO) technique for complex tibial shaft fracture.

TTo evaluate the clinical and radiological results of the treatment of complex tibial shaft fracture (AO/OTA type 42-C) with minimally invasive plate osteosynthesis(MIPO). Twenty patients diagnosed with complex tibial shaft fracture without extension to the articular surface and treated with MIPO, including 9 cases of AO/OTA type 42-C2 and 11 cases of AO/OTA type 42-C3, 6 of which were open fractures. External fixation was used for open fractures until the soft tissue damage had healed; then, 2nd stage operation with MIPO was performed to stabilize the fracture.

Midterm results of coracoclavicular stabilization with double augmentation for acute acromioclavicular dislocation.

Introduction: Numerous techniques have been introduced for the treatment of acute acromioclavicular (AC) joint dislocation. We aim to report the midterm results of coracoclavicular (CC) stabilization with double augmentation for the acute AC joint dislocation.

Case Description: Forty-three patients who underwent surgery for acute AC joint dislocation were followed up for an average of 59.

Comparison of dexmedetomidine and epinephrine as an adjuvant to 1% mepivacaine in brachial plexus block.

Background: Dexmedetomidine extends the duration of nerve block when administered perineurally together with local anesthetics by central and/or peripheral action. In this study, we compared the duration of nerve block between dexmedetomidine and epinephrine as an adjuvant to 1% mepivacaine in infraclavicular brachial plexus block.

Methods: Thirty patients, scheduled for upper limb surgery were assigned randomly to 3 groups of 10 patients each.

Femoral nerve palsy with patella fracture.

Femoral neuropathy may be associated with various etiologies and can cause severe walking disability. We present the case of a 25-year-old woman who underwent surgical repair for a patella fracture and complained of lower extremity pain, paresthesia, and weakness postoperatively. Electromyography and magnetic resonance imaging (MRI) revealed partial peripheral neuropathy of the left femoral nerve associated with the patella fracture.

Modified combined approach for distal humerus shaft fracture: anterolateral and lateral bimodal approach.

Background: Due to the anatomical nature of the radial nerve, dissection and attainment of an adequate operative field in mid to distal humerus fracture is dangerous and limited. We devised a combined anterolateral and lateral approach that ensures protection of the radial nerve. This is achieved by performing bimodal dissection of the proximal humerus anteriorly and the distal humerus laterally.

Correlation between stress shielding and clinical outcomes after total hip arthroplasty with extensively porous coated stems.

Relations between stress shielding and the clinical outcomes of total hip arthroplasty(THA) remain topics of debate. This study was performed on 51 patients that underwent unilateral primary THA with an extensively porous coated stem. Contralateral normal femurs were used as controls.

Subsequent hip fracture in osteoporotic hip fracture patients.

Purpose: A significant number of patients who have experienced previous surgical treatment for an osteoporotic hip fracture experience a subsequent hip fracture (SHF) on the opposite side. This study aims to analyze the risk factors and the correlation between osteoporosis and SHF on the opposite side in order to assess the usefulness of bisphosphonate treatment for the prevention of SHFs.

Materials And Methods: We included 517 patients treated from March 1997 to April 2009 in this study.

Prevalence and risk factors of thromboembolism after joint arthroplasty without chemical thromboprophylaxis in an Asian population.

Venous thromboembolism (VTE) is a serious complication after major orthopedic surgery. This study examined the prevalence and risk factors of VTE in patients undergoing arthroplasty without thromboprophylaxis. A total of 1608 patients who underwent elective knee or hip arthroplasty between 1996 and 2009 were evaluated.

A case of fungal arthritis caused by Hansenula anomala.

Hansenula anomala (H. anomaly) is part of the normal flora in the alimentary tract and throat. It has been reported to be an organism causing opportunistic infections in immunocompromised patients.

Degeneration of acetabular articular cartilage to bipolar hemiarthroplasty.

Purpose: This study examined the rate of degeneration of acetabular cartilage by the bipolar head according to time, and also which clinical factors are related to the degeneration of acetabular cartilage.

Materials And Methods: Among 192 patients (226 hip joints) who received bipolar hemiarthroplasty from August 1996 to August 2002, 61 patients (65 hip joints) were enrolled in this study, who were followed up for more than 2 years and showed no signs of dislocation, infection, or functional problems. A modified form of a computer assisted vector wear analysis program was used to measure the rate of degeneration of the acetabular cartilage.

Minimally invasive coracoclavicular stabilization with suture anchors for acute acromioclavicular dislocation.

Background: The management of acute acromioclavicular (AC) joint dislocation is controversial.

Purpose: The authors describe a surgical technique involving securing the clavicle to the coracoid process using suture anchors for the treatment of acute AC joint injury.

Study Design: Case series; Level of evidence, 4.

Short fusion versus long fusion for degenerative lumbar scoliosis.

The extent of fusion for degenerative lumbar scoliosis has not yet been determined. The purpose of this study was to compare the results of short fusion versus long fusion for degenerative lumbar scoliosis. Fifty patients (mean age 65.
