Superior locking plate with braided PDS coracoclavicular fixation for the unstable distal clavicle fracture: a technical trick and case series.

The ideal method of operative fixation for unstable distal clavicle fractures remains controversial, with particular emphasis on the need to restore the normal coracoclavicular distance. Our preferred method of fixation includes open reduction and internal fixation with a distal clavicle locking plate in combination with a polydioxanone suture wrapped around the plate and coracoid to restore the coracoclavicular distance and offload the bony repair. The purpose of this study is to report clinical, radiographic, and functional outcomes in patients with unstable distal clavicle fractures treated with this method of fixation.

Incidence, treatment, and outcomes of modern dual-mobility intraprosthetic dissociations.

Aims: Dual-mobility (DM) components are increasingly used to prevent and treat dislocation after total hip arthroplasty (THA). Intraprosthetic dissociation (IPD) is a rare complication of DM that is believed to have decreased with contemporary implants. This study aimed to report incidence, treatment, and outcomes of contemporary DM IPD.

The Frank Stinchfield Award: Assembly and Dissociation Forces Differ Between Commonly Used Dual Mobility Implants: A Biomechanical Study.

Background: Intraprosthetic dissociation (IPD) is a complication unique to dual mobility (DM) implants where the outer polyethylene head dissociates from the inner femoral head. Increasing reports of IPD at the time of closed reduction of large head DM dislocations prompted this biomechanical study evaluating the assembly and dissociation forces of DM heads.

Methods: We tested 17 polyethylene DM heads from 5 vendors.

Dislocated and Dissociated Dual-Mobility Components Are Easily Missed and More Than Half Fail Closed Reduction: Six Tips to Aid Management.

Unlabelled: Dual-mobility (DM) implants reduce the risk of dislocation in patients who have undergone total hip arthroplasty (THA); however, DM implants are at risk for large-head dislocation and intraprosthetic dissociation (IPD), where the inner femoral head dissociates from the outer polyethylene head. This study aimed to report the incidence of DM dislocation and IPD, evaluate the rate of recognition of IPD before and after reduction, investigate the outcomes of these complications, and provide treatment recommendations for their management.

Methods: Between 2010 and 2021, 695 primary and 758 revision THAs were performed with DM constructs at a single institution.

Lack of radiosensitivity predicts poor disease specific survival in myxoid liposarcoma.

Background: Compared to other sarcomas, myxoid liposarcoma (ML) is known to be radiosensitive, with improved oncologic outcomes. Although these tumors "shrink" following radiotherapy, there is a paucity of data examining the degree of radiosensitivity and oncologic outcome. The purpose of the study was to evaluate pre- and postradiotherapy tumor volume to determine if size reduction impacts outcome.

Surgical Outcomes of Primary Dermatofibrosarcoma Protuberans: A Retrospective, Multicenter Study.

Background: Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive tumor with a low rate of metastatic disease. Previous series have shown a superiority of Mohs micrographic surgery (MMS) compared with wide local excision (WLE). Likewise, there is paucity of data examining the long-term follow-up of patients.

Preoperative Antibiotics Influence Culture Yield in the Treatment of Hand, Wrist, and Forearm Infections.

Unlabelled: When treating upper-extremity infections, clinicians frequently must decide whether to initiate antibiotics or delay them with the goal of optimizing culture yield at the time of surgical debridement. The purpose of this study was to determine whether the administration of preoperative antibiotics affects intraoperative culture yield and whether there is a "safe" interval prior to culture acquisition within which antibiotics can be administered without affecting culture yield.

Methods: We conducted a retrospective review of 470 consecutive patients who underwent debridement for a presumed acute infection of the hand, wrist, or forearm at a single tertiary care center between January 2015 and May 2020.

Long-term Outcome of Acral Ewing Sarcoma.

Background/aim: Ewing sarcoma is a common primary bone tumor, often located in the distal femur or pelvis. Acral Ewing sarcoma of the upper extremity is exceedingly rare. The aim of this study was to review our institution's experience with the management of rare acral Ewing sarcomas.

Preoperative Risk Factors for Fibrosarcomatous Transformation in Dermatofibrosarcoma Protuberans.

Background/aim: Dermat of ibrosarcoma protuberans (DFSP) is a soft-tissue sarcoma with a high risk of local recurrence, though typically never metastasizes. DFSP can transform into high-grade fibrosarcoma (DFSP-FS), which has a risk of metastasis. Currently, treatment for DFSP includes Moh's micrographic surgery (MMS); however, this is not recommended for DFSP-FS.

Free Functional Latissimus Dorsi Reconstruction of the Quadriceps and Hamstrings following Oncologic Resection of Soft Tissue Sarcomas of the Thigh.

Background: Limb-salvage surgery combined with radiotherapy has become the primary treatment for soft tissue sarcomas of the extremity. Free functional latissimus flaps (FFLF) are an option to restore function in the setting of volumetric muscle loss. The purpose of the current study was to examine the use of FFLF in patients undergoing resection of thigh sarcoma.

Anatomic total shoulder arthroplasty for primary glenohumeral osteoarthritis is associated with excellent outcomes and low revision rates in the elderly.

Background: The relative indications of anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) continue to evolve. Some surgeons favor RSA over TSA for elderly patients with primary glenohumeral osteoarthritis (GHOA) and an intact rotator cuff due to fear of a postoperative (secondary) rotator cuff tear in this age group. However, RSA is associated with unique complications and a worse functional arc of motion compared with TSA.

Outcome of Soft-tissue Reconstruction in the Setting of Combined Preoperative and Intraoperative Radiotherapy for Extremity Soft-tissue Sarcomas.

Background/aim: Reconstruction for soft-tissue sarcomas is complex and often uses soft-tissue flaps. To preserve critical structures, intraoperative radiotherapy (IORT) can be used to boost the total dose to these critical structures and close margins; however, there are limited data on the outcome of soft-tissue reconstruction in patients treated with IORT.

Patients And Methods: Twenty patients received IORT with soft-tissue flap coverage.

Hospital for Special Surgery ACL Registry: 2-Year Outcomes Suggest Low Revision and Return to OR Rates.

Background: Anterior cruciate ligament (ACL) injuries are among the most common knee injuries. Patient outcomes, rate of subsequent operations, and rate of subsequent ACL reconstruction following primary ACL reconstruction need to be evaluated.

Questions/purposes: This study was designed to answer the following questions: (1) What is the return to surgery (OR) rate following primary ACL reconstruction and (2) what is the revision ACL reconstruction rate?

Methods: Data was drawn from the Hospital for Special Surgery (HSS) ACL Registry.
