Early experience with a 3-D printed porous surface, fixed-bearing, total ankle arthroplasty: A minimum of 2-year follow-up.

Background: This is a pilot study reviewing patients undergoing ankle replacement with the 3-D printed INFINITY™ with ADAPTIS™ total ankle arthroplasty (TAA) system.

Methods: A retrospective review was conducted of patients with a minimum two-year follow-up who underwent TAA with the INFINITY™ with ADAPTIS™ implant system. Outcome measures include implant survivorship, complications with subsequent reoperations, patient reported outcomes, and radiologic subsidence or radiolucency.

Rapid recovery pathway without epidural catheter analgesia for surgical treatment of adolescent idiopathic scoliosis: a comparative study.

Purpose: To assess effectiveness of a rapid recovery pathway (RRP) without epidural catheter analgesia (ECA) or intravenous patient controlled analgesia (PCA) in accelerating recovery and decreasing opioid consumption in patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion (PSF).

Methods: A retrospective cohort study included collection of demographics, ECA use, IV PCA, postoperative opioid consumption, postoperative pain scores, and reoperation rate. Opioid consumption was calculated using morphine milligram equivalents (MME).

Repeat posterior wall acetabular fracture-dislocation: High-energy trauma as a 'second hit phenomenon'.

Acetabular fractures are injuries that require significant force transmission, especially when associated with a femoral head dislocation. The mechanism of injury is typically in the setting of a high-speed motor vehicle collision. In a similar manner, this is an injury that is highly demanding for the orthopaedic trauma surgeon to treat as well.

MRI diagnosis of suprascapular neuropathy using spinoglenoid notch distension.

Purpose: To assess the use of a spinoglenoid notch distension measurement as a radiographic marker on MRI to aid the diagnosis of suprascapular neuropathy.

Methods: Spinoglenoid notch distension was compared on MRI by blinded independent observers for two patient cohorts: one group with an electromyography/nerve conduction study confirmed diagnosis of suprascapular neuropathy who underwent arthroscopic suprascapular nerve decompression, and a control group of patients aged 18-30 years with a normal shoulder MRI.

Results: Sixty suprascapular nerve patients (average age 52 years) were compared to 47 control patients (average age 24 years).

Reamer-Irrigator-Aspirator Multiuse Application in the Treatment of Chronic Osteomyelitis.

Introduction: The treatment of chronic intramedullary infection of the long bones relies on microbe-specific antibiotics in conjunction with surgical removal of infected necrotic material. We discuss the use of reamer-irrigator-aspirator(RIA) for debridement of the intramedullary canal instead of conventional reaming techniques. This is the first case report to explore the use of RIA for osteomyelitis.

Treatment of Rigid Hammer-Toe Deformity: Permanent Versus Removable Implant Selection.

Hammer-toe deformities that fail nonoperative treatment can be successfully addressed with proximal interphalangeal joint resection arthroplasty or fusion. The goal of surgery is to eliminate the deformity and rigidly fix the toe in a well-aligned position. Hammer-toe correction procedures can be performed with temporary Kirschner wire (K-wire) fixation for 3 to 6 weeks with high success rates.

Anatomic parameters of the sacral lamina for osteosynthesis in transverse sacral fractures.

Purpose: To analyze the morphometric parameters of the dorsal sacral lamina and pedicles to determine if there is adequate bony architecture to support plate osteosynthesis.

Methods: Two reviewers performed measurements on 98 randomly selected high-resolution CT scans of the pelvis to quantify the bony anatomy of the sacral lamina. Measurements included the depths of the lamina at each sacral level, the trajectory and depth of the sacral pedicles from the sacral lamina, and the width of the sacral canal.
