Superior capsular reconstruction using hybrid graft for irreparable massive rotator cuff tear.

Purpose: To evaluate the clinical and radiological outcomes of arthroscopic superior capsular reconstruction (SCR) using hybrid grafts composed of tensor fascia lata autografts and human dermal allografts.

Methods: This study included 30 patients with chronic irreparable posterosuperior rotator cuff tears (RCTs) who underwent arthroscopic SCR using a hybrid graft composed of tensor fascia lata autograft and human dermal allograft. Clinical outcomes were evaluated using the pain visual analogue scale score, shoulder range of motion, American Shoulder and Elbow Surgeons score, constant score, University of California-Los Angeles score, and simple shoulder test score preoperatively and at least 2 years after surgery.

Selective Serotonin Reuptake Inhibitor Promotes Bone-Tendon Interface Healing in a Rotator Cuff Tear Rat Model.

Background: Selective serotonin reuptake inhibitor (SSRI) is believed to accelerate wound healing, and thus expected to have a positive effect on rotator cuff repair. We hypothesized that SSRI has a positive effect on the healing of the bone-tendon interface (BTI), and improved rotator cuff tear healing would be confirmed by mechanical strength measurements and histological assessment of the restored tendon.

Methods: The study used 40 adult male Sprague-Dawley wild-type rats.

Precontoured Plate Fixation for Incomplete Atypical Diaphyseal Fracture of Femur using Three-Dimensional Printing Rapid Prototyping: Two Cases Reports.

Background: Reconstruction intramedullary nail spanning the whole length of the femur has been the gold standard treatment for complete atypical diaphyseal fractures of the femur (ADF). However, in cases of incomplete ADF combined with severe bowing, this approach might have complications and lead to iatrogenic complete fracture. We report two cases of incomplete ADF with severe bowing using a precontoured plate (PCP) after rapid prototyping (RP) of the deformed femurs with three-dimensional printing (3DP) technology.

Does proximal femoral nail antirotation achieve better outcome than previous-generation proximal femoral nail?

Background: There are few studies in the literature comparing the clinical outcomes and radiographic results of proximal femoral nail (PFN) and proximal femoral nail antirotation (PFNA) for pertrochanteric femoral fracture (PFF) in elderly patients.

Aim: To evaluate both clinical and radiographic outcomes after fixation with PFN and PFNA in an elderly patient population.

Methods: One hundred fifty-eight patients older than 65 years with PFF who underwent fixation with either PFN or PFNA were included.

Feasibility of the Inner-Side-Out Use of the LC-DCP for Periprosthetic Femoral Fracture in Total Hip Arthroplasty.

Background: The optimal technique for plate fixation to treat type B and C periprosthetic femoral fractures (PFFs) is unclear. The purpose of this study is to evaluate the radiographic results of inner-side-out limited contact dynamic compression plate (LC-DCP) to treat PFFs during or after total hip arthroplasty (THA).

Methods: This retrospective study comprised of four men and six women with an average age of 64.

Fatty Degeneration of the Rotator Cuff Reflects Shoulder Strength Deficits in Patients With Rotator Cuff Tears.

Fatty degeneration is an important clinical factor in patients with rotator cuff tears. Goutallier grade, occupation ratio, and tangent sign help identify fatty degeneration; however, little is known about how closely these measurement techniques correlate with actual muscle strength deficits. The authors evaluated each method's ability to determine the correlation between fatty degeneration and muscle strength deficits.

Rotator cuff tear and sarcopenia: are these related?

Background: Sarcopenia is the loss of muscle mass and consequent loss of muscle function with aging. Its prevalence among the general population is 12% to 30% in those aged >60 years. We evaluated (1) the difference in the prevalence of sarcopenia between patients with rotator cuff tear and controls and (2) the sarcopenia severity according to the size of the rotator cuff tear.
