Ulnar-Sided Sclerosis of the Lunate Does Not Affect Outcomes in Patients Undergoing Volar Locking Plate Fixation for Distal Radius Fracture.

Background And Aim: Radial shortening after distal radius fracture causes ulnar impaction, and a mild reduction loss of radial height occurs even after volar locking plate fixation. This study aimed to determine whether preoperative ulnar-sided sclerosis affects clinical outcomes after volar locking plate fixation for distal radius fracture (DRF).

Method: Among 369 patients who underwent volar locking plate fixation for DRF, 18 with preoperative ulnar-sided sclerosis of the lunate were included in Group A and compared to a 1:4 age-, sex- and fracture-pattern-matched cohort without sclerosis (72 patients, Group B).

Risk factors for nonunion in patients with transcondylar fracture of the distal humerus after open reduction and internal fixation.

Background: Transcondylar fractures have been reported to rarely occur in the distal humerus, and stable fixation is difficult because of the unique fracture pattern. However, few studies have reported the risk factors for nonunion after open reduction and internal fixation (ORIF). This study aimed to evaluate the demographic and surgical risk factors for nonunion in patients who had undergone ORIF for transcondylar fractures.

Arthroscopic Broström-Gould repair has comparable radiological and clinical outcomes compared to traditional open Broström-Gould repair in high-demand patients.

Purpose: This study sought to confirm whether traditional open Broström-Gould repair and arthroscopic Broström-Gould repair for chronic ankle instability (CAI) would produce comparable radiological and clinical outcomes in high-demand patients.

Methods: This retrospective case-cohort study included high-demand patients, as determined by a pre-injury Tegner Activity Level ≥ 6, who underwent Broström-Gould repair and were followed up for ≥ 2 years. Patients were divided into the arthroscopic Broström-Gould repair group (AS Group) and the open Broström-Gould repair group (Open Group).

Complications associated with open reduction and internal fixation for adult distal humerus fractures: a multicenter retrospective study.

Background: Open reduction and plate fixation are the preferred treatment options for most distal humerus fractures in adults. However, it is often challenging for orthopedic surgeons because of the complex anatomy and the difficulty in achieving stable fixation. This multicenter study aimed to analyze the complication types and rates of patients with distal humerus fractures treated with open reduction and plate fixation, and compare the results with those found in the literature.

Osteosarcoma Arising in Fibrous Dysplasia of the Long Bone: Characteristic Images and Molecular Profiles.

Fibrous dysplasia (FD) is a benign fibro-osseous lesion that frequently involves the craniofacial bones and femur. Malignant transformation of FD is a rare occurrence. We report a 38-year-old woman with osteosarcoma (OS) arising from FD of the femur.

Purpose: The purpose of this study was to compare the clinical outcomes of A1 pulley release with ulnar superficialis slip resection (group A) and simple A1 pulley release (group B) in trigger finger with flexion contracture of the proximal interphalangeal (PIP) joint.

Methods: From January 2016 to December 2019, the 2 surgical procedures were performed alternately every year for trigger fingers with preoperative PIP joint flexion contractures of ≥10°. Twenty-six fingers in group A and 29 fingers in group B that were followed up for >1 year were reviewed in this retrospective study.

Characteristics of surgically treated Guyon canal syndrome: A multicenter retrospective study.

Guyon canal (GC) syndrome is a rare peripheral neuropathy involving the distal part of the ulnar nerve. Several causes are associated with GC syndrome, including anatomic variations, space-occupying tumors, and trauma. Because of disease rarity, the only reported studies of GC syndrome are case series with small sample size.

Risk Factors for Non-Union after Open Reduction and Internal Fixation in Patients with Distal Humerus Fractures.

Background: Only a few studies have reported on the risk factors for non-union after open reduction and internal fixation (ORIF) in distal humerus fractures.

Methods: We retrospectively reviewed 155 patients who underwent ORIF for distal humerus fractures from January 2008 to June 2020. Various patient factors, including body mass index (BMI), diabetes mellitus (DM), and combined fracture, as well as surgical factors, including fixation methods (e.

Dorsal plating versus volar plating with limited dorsal open reduction in the management of AO type C3 distal radius fractures with impacted articular fragments: A retrospective comparative study.

Objective: The aim of this study was to compare the outcomes of dorsal plating versus volar plating with limited dorsal open reduction in the management of AO type C3 distal radius fractures with impacted articular fragments.

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.

Factors Affecting the Occurrence of Late Median Nerve Neuropathy After Open Reduction and Volar Locking Plate Fixation of Distal Radius Fracture.

It is well-known that late median nerve neuropathy can occur after open reduction and internal fixation (ORIF) of distal radius fracture (DRF). The current study investigated the predictive factors of late median nerve neuropathy after ORIF with a volar locking plate for DRF. The authors retrospectively reviewed 712 patients who underwent ORIF using a volar locking plate after DRF at 3 medical institutions between 2006 and 2017.

Parosteal Lipoma Associated with a Growing Osteochondroma of the Right Ilium.

Parosteal lipoma is a rare type of lipoma, the incidence being approximately 0.3% of all lipomas. Moreover, parosteal lipoma coexisting with osteochondroma is extremely rare.

Complications associated with volar locking plate fixation for distal radius fractures in 1955 cases: A multicentre retrospective study.

Purpose: Since volar locking plates (VLPs) have the benefits of more stable fixation and fewer complications, VLP osteosynthesis is now the preferred osteosynthesis method in the operative management of distal radius fractures (DRF). Along with the increases in operative management of VLP, the character and frequency of complications have changed. Thus, this multicentre study aimed to identify the characteristics of patients with DRFs who were treated with VLP fixation, describe the complication types and rates related to the procedure, and compare the results with those found in the literature.

Evaluation of Stress Radiographs Taken Before and After Spinal Anesthesia in Patients With Chronic Ankle Instability.

Stress radiography is known as an important diagnostic tool for confirming mechanical instability in patients with chronic ankle instability. However, there are no reports on how muscle guarding caused by the stress applied on the ankle during stress radiography affects test outcomes. Thus, this study aimed to analyze the effects of muscle guarding caused by stress radiography on outcomes by performing stress radiography before and after anesthesia.

Comparison between simple release and Z-plasty of retinaculum for de Quervain's disease: a retrospective study.

We compared two surgical procedures for de Quervain's disease that was not responsive to conservative treatment. Group A (simple release) consisted of 38 patients and group B (Z-plasty of the retinaculum) included 36 patients. The visual analogue scale score and the Disabilities of the Arm, Shoulder and Hand Score improved significantly after surgery; there were no statistical differences in outcome between the two groups.

Onlay vascularized fibular grafting as a salvage procedure for the management of nonunion after reconstruction of the femur following tumor resection.

Purpose: The femur is prone to nonunion after biologic reconstruction following tumor resection, due to high bending forces. Nonunion at the host-graft junction is difficult to treat since the graft is in an avascular state. We aimed to investigate the clinical and radiographic results of an onlay free vascularized fibular grafting (VFG) as a salvage procedure for nonunion management after biologic reconstruction of the femur following bone tumor resection.

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.

Assessment of Ankle Mortise Instability After Isolated Supination-External Rotation Lateral Malleolar Fractures.

Background: The diagnosis of clinically important instability following isolated supination-external rotation (SER) distal fibular fractures is a challenge. The purpose of this study was to investigate the accuracy of clinical findings including medial tenderness, swelling, and ecchymosis, combined with the gravity stress test and magnetic resonance imaging (MRI), in the assessment of ankle mortise stability in association with isolated SER-type lateral malleolar fractures. The external rotation (ER) stress test was used as the reference with which the methods of assessment were compared.

Analysis of the Changes in the Clinical Outcomes According to Time After Arthroscopic Microfracture of Osteochondral Lesions of the Talus.

Background:: Arthroscopic microfracture can effectively treat osteochondral lesions of the talus (OLTs). However, very few studies have reported on symptomatic improvement duration and time when symptomatic improvement ceases. This study aimed to investigate the clinical outcome changes after arthroscopic microfracture in patients with OLT.

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