Wrist Reconstruction Using Free Vascularized Fibular Head Graft Following Intralesional Excision for Campanacci Grade 3 Giant Cell Tumors Involving the Articular Surface of the Distal Radius.

Reconstruction with a free vascularized fibular head graft after en bloc excision of a Campanacci grade 3 giant cell tumor of bone in the distal radius can effectively control local recurrence. However, it leads to the loss of wrist movement, subsequent radiocarpal subluxation, and an osteoarthritic change. Another treatment option for grade 3 lesions is intralesional excision and cementation, which preserves wrist movement but does not restore the articular surface.

Extension Block Pinning versus percutaneous Fragment Reduction with a Towel Clip and extension Block Pinning with direct Pin Fixation for Treatment of Mallet Fracture.

Purpose: This study compared the clinical and radiographic results between extension block pinning (Group A) and percutaneous reduction of the dorsal fragment with a towel clip followed by extension block pinning with direct pin fixation (Group B) for the treatment of mallet fractures.

Patients And Methods: A total of 69 patients (group A = 34 patients, group B = 35 patients) who underwent operative treatment for mallet fractures from June 2008 to November 2017 with ≥ 6 months post-surgical follow-up were analysed retrospectively. The extent of subluxation of the distal interphalangeal joint, articular involvement of fracture fragment, fracture gap, and articular step-off were examined on plain radiographs before and after surgery.

Management of calcific myonecrosis with a sinus tract: A case report.

Rationale: Calcific myonecrosis is a very rare late sequela that occurs in patients who have had trauma accompanied by vascular compromise, in which a single muscle or entire muscles in a compartment undergoes necrosis and form a calcified mass. It is mostly a benign entity, but some cases cause bone destruction and form non-healing chronic sinuses. In such cases, wound management becomes difficult and there is a potential risk of secondary infection.

Factors Causing Prolonged Postoperative Symptoms Despite Absence of Complications After A1 Pulley Release for Trigger Finger.

Purpose: This study aimed to investigate the incidence and prognostic factors for prolonged postoperative symptoms after open A1 pulley release in patients with trigger finger, despite absence of any complications.

Methods: We reviewed 109 patients (78 single-finger involvement, 31 multiple-finger involvement) who underwent open A1 pulley release for trigger finger from 2010 to 2016, with 8 weeks or longer postsurgical follow-up and without postoperative complications. The group had 16 men and 93 women, with mean age of 56 years (range, 21-81 years), and average follow-up period of 24.

Morphological Study of the Proximal Fibular Articular Surface Using Computed Tomography: Which Side Is Preferred for Proximal Fibular Flap in Wrist Arthroplasty?

 Although proximal fibular flaps have been widely applied in wrist arthroplasty, controversy remains regarding which side of the proximal fibula is better for reconstruction of the distal radius. If the articular surface of the proximal fibula shows dorsal tilting, the ipsilateral (right) proximal fibula should be harvested in right wrist arthroplasty because the articular surface of the distal radius normally has volar tilt. This study investigated anatomical similarities between the proximal fibular articular surface and the distal radius articular surface based on morphologic analysis of the proximal fibula using computed tomography (CT).

A New Method to Control Tendon Tension in the Transfer of Extensor Indicis Proprius to Extensor Pollicis Longus Rupture.

This study evaluated the outcomes of extensor indicis proprius (EIP) transfer based on varying degrees of thumb extension after EIP transfer and elongation of the EIP. A total of 24 cases with extensor pollicis longus (EPL) ruptures who underwent EIP to EPL transfer were analyzed prospectively. The EIP transfer was performed with neutral wrist positioning.

Pedicled chimeric gastrocnemius-medial sural artery adipofascial flap for reconstruction of anterolateral defects of the knee.

A medial gastrocnemius muscle flap is useful for soft tissue reconstruction of the knee and proximal tibia but insufficient to cover defects involving the lateral aspect of the knee. The purpose of this report is to present the results of the use of a pedicled chimeric gastrocnemius-medial sural artery adipofascial flap for reconstruction of defects of the knee and lateral aspect of the knee. Six patients underwent soft tissue reconstruction of the knee by means of the described procedure.

Outcomes of wrist arthroplasty using a free vascularized fibular head graft for Enneking stage II giant cell tumors of the distal radius.

The purpose of this study was to report the clinical outcomes of wrist arthroplasty with a free vascularized fibular head graft (FVFHG) and to highlight some considerations that may affect outcomes. FVFHG was performed on 12 patients with giant cell tumors of the distal radius between April 1984 and July 2005. The mean age of patients was 33 years.

Outcomes of anterolateral thigh-free flaps and conversion from external to internal fixation with bone grafting in gustilo type IIIB open tibial fractures.

The purpose of this study was to analyze the utility and the clinical outcomes of anterolateral thigh (ALT)-free flaps and conversion from external to internal fixation with plating and bone grafting in Gustilo type IIIB open tibial fractures. A total of 21 patients were analyzed retrospectively. The mean follow-up period was 18 months and the mean age was 46.

Anatomic reduction of mallet fractures using extension block and additional intrafocal pinning techniques.

Background: The purpose of this article is to report the efficacy of the extension block pinning and additional intrafocal pinning technique applied to cases whose mallet fractures were not reduced with extension block pinning alone.

Methods: We retrospectively reviewed 14 digits with 14 patients who were treated with the extension block pinning and additional intrafocal pinning technique. There were eight men and six women with an average age of 34 years.

Effect of hyaluronic acid-carboxymethylcellulose solution on perineural scar formation after sciatic nerve repair in rats.

Background: Scar tissue formation is the major cause of failure in peripheral nerve surgery. Use of a hyaluronic acid-carboxymethylcellulose (HA-CMC) membrane (Seprafilm) as a solid anti-adhesion barrier agent is one of the therapeutic approaches to reduce postoperative scar tissue formation. However, a solid membrane may not be suitable for repair of a weak peripheral nerve site.

Reconstruction of composite tibial defect with free flaps and ipsilateral vascularized fibular transposition.

Composite defects of the tibia following open fractures are among the most challenging of clinical problems. The aim of this study is to report the results of treatment using a free flap procedure followed by ipsilateral vascularized fibular transposition (IVFT) for reconstruction of composite tibial defects. Ten patients underwent a free flap procedure followed by IVFT and plating.

Reverse lateral supramalleolar adipofascial flap and skin grafting for one-stage soft tissue reconstruction of foot and ankle joint.

The aim of this report is to present the clinical result and efficacy of reverse lateral supramalleolar adipofascial flap and skin grafting for one stage soft tissue reconstruction of the foot and ankle joints. Reconstruction using a reverse lateral supramalleolar adipofascial flap and skin grafting was performed in eight cases between January 2005 and March 2009. All the subjects were male with a mean age of 53 years.

Lengthening of intercalary allograft combined with free vascularized fibular graft after reconstruction in pediatric osteosarcoma of femur.

Involvement of the growth plate by a tumor or an injured growth plate during surgical procedures causes a discrepancy in the limb length. To address this problem,distraction osteogenesis is a well-established procedure for the treatment of defect and leg length discrepancy inviable bone tissues. We present the lengthening of an intercalary allograft combined with a vascularized fibular graft after reconstruction of osteosarcoma in the femoral metaphysis of a 10-year-old boy.
