Clinical Features and Treatment of Intra-Tendinous Suture Reaction Following Achilles Tendon Repair Using Nonabsorbable Suture Material: A Retrospective Case Series Study.

We aimed to investigate the clinical manifestations, radiological findings, and therapeutic outcome of treatment for patients with surgically confirmed foreign body reaction following an Achilles tendon repair using non-absorbable suture material. Eight consecutive patients who were confirmed as having an intra-tendinous suture foreign body reaction in the histopathological report were enrolled in this study. Medical records of all patients in terms of clinical and radiological features were retrieved.

Biportal endoscopic posterior lumbar decompression and vertebroplasty for extremely elderly patients affected by lower lumbar delayed vertebral collapse with lumbosacral radiculopathy.

Background: Lower lumbar osteoporotic vertebral compression fracture in extremely elderly patients can often lead to lumbosacral radiculopathy (LSR) due to delayed vertebral collapse (DVC). Surgical intervention requires posterior instrumented lumbar fusion as well as vertebral augmentation or anterior column reconstruction depending on the cleft formation and intravertebral instability. However, it is necessary to decide on surgery in consideration of the patient's frail status, surgical invasiveness, and rehabilitation.

Intermediate-term Patient-Reported Outcomes and Radiographic Evaluation Following Intramedullary- vs Extramedullary-Referenced Total Ankle Replacement.

Background: The purpose of this study was to report on the radiographic outcomes, clinical outcomes, and implant survivorship following extramedullary-referenced (EMr) vs intramedullary-referenced (IMr) total ankle replacement (TAR).

Methods: From May 2007 to February 2018, a consecutive series of patients with end-stage tibiotalar osteoarthritis undergoing TAR was enrolled in this study. Analyses were performed comparing IMr vs EMr components for patient-reported outcomes data, pre- and postoperative radiographic ankle alignment, concomitant procedures, and complications.

Clinical outcome of biportal endoscopic revisional lumbar discectomy for recurrent lumbar disc herniation.

Background: Although literature provides evidence regarding the superiority of surgery over conservative treatment in patients with lumbar disc herniation, recurrent lumbar disc herniation (RLDH) was the indication for reoperation in 62% of the cases. The major problem with revisional lumbar discectomy (RLD) is that the epidural scar tissue is not clearly isolated from the boundaries of the dura matter and nerve roots; therefore, unintended durotomy and nerve root injury may occur. The biportal endoscopic (BE) technique is a newly emerging minimally invasive spine surgical modality.

Adverse events involving hallux metatarsophalangeal joint implants: Analysis of the United States Food and Drug Administration data from 2010 to 2018.

Background: The prevalence of osteoarthritis of the hallux metatarsophalangeal joint (MTPJ) is 1 in 40 people over the age of 50. Surgical treatment options for MTPJ arthritis include joint preservation, joint resurfacing, and arthrodesis. Hallux MTPJ implants have evolved over the past several decades, but are associated with various complications.

Distal chevron osteotomy with lateral soft tissue release for moderate to severe hallux valgus decided using intraoperative varus stress radiographs.

The purpose of the present study was to investigate the outcomes of distal chevron osteotomy with lateral soft tissue release for moderate to severe hallux valgus. The patients were selected using criteria that included the degree of lateral soft tissue contracture and metatarsocuneiform joint flexibility. The contracture and flexibility were determined from intraoperative varus stress radiographs.

Treatment of traumatic subtalar arthritis with interpositional arthroplasty with tensor fascia lata or fat.

Objective: The aim of this study was to evaluate the results of interpositional arthroplasty with tensor fascia lata or fat as a treatment for traumatic subtalar joint arthritis after a fracture of the calcaneus.

Methods: From August 2006 to March 2008, 22 patients with traumatic subtalar joint arthritis were enrolled in this study. Tensor fascia lata was implanted for 7 patients who previously underwent surgery with the extensive lateral approach.

Arthroscopy combined with hardware removal for chronic pain after ankle fracture.

Purpose: The purpose of this study was to evaluate the effectiveness of arthroscopy combined with hardware removal for chronic pain after satisfactory healing of an ankle fracture. We hypothesized that combining hardware removal with arthroscopy for the intra-articular pathology would improve residual complaints more so than hardware removal alone.

Methods: The outcomes of the 53 young male patients with chronic pain after healed ankle fracture treated with two different therapeutic plans: (1) conservative treatment after hardware removal (group A) and (2) arthroscopic intervention with hardware removal (group B) were prospectively studied.

Closed antegrade intramedullary pinning for reduction and fixation of metatarsal fractures.

The purpose of this study was to present the results of the metatarsal fractures treated with a closed antegrade intramedullary pinning technique. The records of 35 consecutive patients with metatarsal fractures operated on from August 2005 to June 2010 by the authors were retrospectively reviewed. Four patients were not contactable and 1 patient refused to participate.

Effect of protein concentrations of bovine serum albumin and γ-globulin on the frictional response of a cobalt-chromium femoral head.

The study aims to identify the concentration-dependent role of bovine serum albumin (BSA) and γ-globulin in the lubricating ability of a cobalt-chromium femoral head. The frictional coefficients of the cobalt-chromium femoral head decreased with increasing BSA concentrations from 10 to 40 mg/ml and showed statistical differences between any of the BSA concentration groups, except between the 30 and 40 mg/ml concentration groups. In γ-globulin, the frictional coefficients significantly decreased at concentrations of 2.

Role of intraoperative varus stress test for lateral soft tissue release during chevron bunion procedure.

Background: The purpose of this study was to evaluate the clinical results of distal chevron osteotomy performed in conjunction with selective lateral soft tissue release. The criterion for doing a lateral soft tissue release was assessed by determining the ease and completeness of passive hallux valgus correction at the time of surgery.

Materials And Methods: Between August 2005 and November 2007, 48 feet in 43 patients classified as having mild to moderate hallux valgus were retrospectively studied.
