Surgical site infection (SSI) after fragility hip fracture (FHF) surgery is associated with increased morbidity and mortality. We aim to utilize several established nutritional and inflammatory indices to characterize patients at risk. A retrospective cohort study of patients 65 years and older, who underwent surgery following FHFs between January 2012 and June 2020.

The effect of patient body mass index and sex on the magnification factor during pre-operative templating for total hip arthroplasty.

Introduction: Pre-operative templating prior to hip arthroplasty has traditionally used implant-company-provided acetates, which assumed a magnification factor between 115% and 120%. In recent years, pre-operative planning has been performed with digital calibration devices, in order to calculate the magnification factor. However, these devices are not without their limitations and are not readily available at many institutions.

Preoperative Pain Catastrophizing and Neuropathic Pain Do Not Predict Length of Stay and Early Post-Operative Complications following Total Joint Arthroplasty.

Background: Both pain catastrophizing and neuropathic pain have been suggested as prospective risk factors for poor postoperative pain outcomes in total joint arthroplasty (TJA).

Objective: We hypothesized that pain catastrophizers, as well as patients with pain characterized as neuropathic, would exhibit higher pain scores, higher early complication rates and longer lengths of stay following primary TJA.

Methods: A prospective, observational study in a single academic institution included 100 patients with end-stage hip or knee osteoarthritis scheduled for TJA.

Risk Factors Associated With de Quervain Tenosynovitis in Postpartum Women.

Background: De Quervain (DQ) disease is caused by stenosis of the first dorsal compartment containing the abductor pollicis longus and extensor pollicis brevis. This condition affects women 6 times more than men and is also commonly reported in pregnant and lactating women. The natural course of the disease and associated risk factors are not well understood.

The quality of immediate postoperative radiographs, performed after total hip replacement in the operating room versus in the post-anesthesia care unit: is there a difference?

Introduction: Currently, there are no clear guidelines regarding the optimal settings for immediate postoperative imaging following total hip arthroplasty (THA). Authors' primary aim was to determine the preferred setting for postoperative radiographs by comparing a technical quality of imaging performed in postanesthesia care unit (PACU) versus operating room (OR).

Materials And Methods: Our study is a retrospective comparison of quality of postoperative radiographs following THAs, performed in PACU versus OR.

Introduction: Surgical site infection (SSI) following fragility hip fracture (FHF) surgery is associated with increased morbidity and mortality.

Significance: Prediction of patients at risk for SSI is fundamental. We aimed to determine whether subcutaneous radiographic fat measurement (SRM) is associated with increased SSI risk.

Unplanned excision of soft tissue sarcoma: does it impact the accuracy of intra-operative pathologic assessment at time of re-excision?

Purpose: An "unplanned excision" refers to soft tissue sarcomas excised without planning imaging studies and a diagnostic biopsy, resulting in the presence of residual disease and usually necessitating a re-excision procedure. We aimed to assess the impact of previous unplanned excisions on the intra-operative pathologic assessment at the time of re-excision, in terms of need to perform repeat assessments and the accuracy to predict margin status of the final pathologic specimen.

Methods: Data was collected for all patients with extremity soft tissue sarcoma who had undergone wide local excision limb salvage surgery or amputation between 2012 and 2017.

Lateral Column Lengthening for Flexible Flat Foot: Was It Short to Begin With?

Background: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column.

Objectives: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter.

C5 Palsy Following Cervical Spine Decompression.

Background: Cervical spinal surgery is considered safe and effective. One of the few specific complications of this procedure is C5 nerve root palsy. Expressed primarily by deltoid muscle and biceps brachii weakness, it is rare and has been related to nerve root traction or to ischemic spinal cord damage.

The Impact of the COVID-19 2020 Pandemic on Hospital Length of Stay Following Fragility Hip Fracture Surgery.

Background: Hip fractures in elderly patients are a major cause of morbidity and mortality. Variability in length of hospital stay (LOS) was evident in this population. The coronavirus disease-2019 (COVID-19) pandemic led to prompt discharge of effected patients in order to reduce contagion risk.

Do cancer patients undergoing surgery for a non-neoplastic related fragility hip fracture have worse outcomes? A retrospective study.

Introduction: An increasing number of patients sustaining a fragility hip fracture (FHF) have either an active diagnosis or a history of cancer. However, little is known about the outcomes of non-malignant related FHF in this group of patients. We aimed to evaluate the mortality and complications rates during hospitalization, as well as at 1-year follow-up within this population.
