Arthroscopic Subscapularis Augmentation With Xenograft Glenoid Bone Block in Patients With Recurrent Anterior Shoulder Instability.

Introduction: The purpose of this study was to investigate the clinical and radiographic outcomes at 2 years for patients who underwent an arthroscopic xenograft bone block procedure plus ASA for recurrent anteroinferior gleno-humeral instability.

Methods: This retrospective study was conducted on patients affected by chronic anteroinferior shoulder instability. The inclusion criteria were as follows: patients must be aged 18 years or older; have recurrent anteroinferior shoulder instability, a glenoid defect >10%, assessment by the Pico area measurement system, anterior capsular insufficiency, and an engaging Hill-Sachs lesion.

Proximal humerus fracture sequelae: are corrective osteotomies still a taboo? The role of three-dimensional preoperative planning and patient-specific surgical guides for proximal humerus corrective osteotomy in combination with reverse shoulder arthroplasty.

Background: Symptomatic proximal humeral fracture sequelae (PHFS) represent a surgical challenge due to the altered bone and soft tissue morphology. The purpose of this study was to report the outcome of Multiplanar Corrective Humeral Osteotomies (MCHOs) in combination with reverse total shoulder arthroplasty (rTSA) performed following a three-dimensional (3D) preoperative planning and using a 3D-printed patient-specific surgical instrumentation (PSI) in type 1C, 1D, and 4 PHFS.

Methods: In this prospective monocentric study, we enrolled patients affected by symptomatic PHFS type 1C, 1D, or 4 of Boileau's classification, treated between 2018 and 2019 with rTSA associated to MCHO and followed-up at 12 and 24 mo.

Therapeutic and prognostic predictive value of the Control Volume severity grade on proximal humerus fractures due to bone fragility.

Background: The treatment of proximal humerus fracture complicated by bone fragility is still controversial. The aim of this study is to compare the Neer classification and the Control Volume severity grade for the accuracy in the selection of the type of treatment and for prognostic evaluation.

Materials And Methods: We retrospectively collected the records of all patients admitted at the Emergency Department of our Institute, from 2013 to 2020, for a closed displaced proximal humerus fracture further investigated with a CT scan before treatment decision.

Osteochondral allograft transplantation for complex distal humeral fractures assisted by 3D computer planning and printing technology: technical note.

Purpose: The surgical treatment of comminuted distal humeral articular fractures (DHF) is challenging and is jeopardized by the high rate of complications. The study aims to describe the application of osteochondral allograft (OCA) transplantation for the treatment of complex DHF assisted with a 3D printed specific instrumentation.

Methods: Retrospective study.

A new classification of impacted proximal humerus fractures based on the morpho-volumetric evaluation of humeral head bone loss with a 3D model.

Background: This study aimed to classify the pathomorphology of impacted proximal humeral fractures according to the control volume theory, with the intention to introduce a severity index to support surgeons in decision making.

Methods: In total, 50 proximal humeral fractures were randomly selected from 200 medical records of adult patients treated from 2009 to 2016. Four nonindependent observers used 2 different imaging modalities (computed tomography scans plus volume rendering; 3D model) to test the classification reliability.

Analysis of early and late clinical and radiologic complications of proximal humeral fractures using open reduction, internal fixation, and intramedullary titanium cage augmentation.

Background: An intramedullary augmentation technique using a titanium cage with different types of hardware can be considered a new option in the management of proximal humeral fractures. This study aimed to report the perioperative, early, and late complications of proximal humeral fractures using the intramedullary augmentation technique.

Methods: From 2005 to 2017, 142 displaced proximal humeral fractures were treated in the same unit by the aforementioned technique.

Triangular block bridge method for surgical treatment of complex proximal humeral fractures: theoretical concept, surgical technique and clinical results.

Introduction: Criteria for classification, indication and choice of a surgical device to treat proximal humeral fractures are still controversial. We report an original technique based on a mechanical concept with a structural principle of a triangle as a rigid body applied to the humeral head fractures in association with other devices. This retrospective study aims to describe in detail the surgical technique and results at long time follow up.

Bilateral reverse total shoulder arthroplasty-functional outcome and activities of daily living.

Background: Reverse total shoulder arthroplasty (rTSA) has gained popularity in recent years, providing good shoulder elevation, yet less predictable rotations. Good rotations are crucial for performance of activities of daily living (ADLs), including personal hygiene. Concerns remain regarding bilateral rTSA over lack of rotations bilaterally and resultant difficulties with ADLs.

Analysis of complications of reverse total shoulder arthroplasty.

Purpose: the aim of this study was to analyze complications of reverse total shoulder arthroplasty (RTSA) used to treat different shoulder diseases.

Methods: from March 2000 to March 2013, 195 RTSA were implanted by the senior Author. The indications for reverse prosthesis surgery were secondary osteoarthritis (OA) in 49 cases, irreparable rotator cuff tear (RCT) in 48 cases, and complex humeral fractures in 75 cases, while 19 were patients requiring surgical revision for first prosthesis implant.

Reconstruction techniques in comparison for reverse shoulder trauma prosthesis in the elderly: a follow-up between 2 and 4 years.

Introduction: The aim of this study was to evaluate the clinical outcome of a bone graft technique called bCAT (bone Collar And Tie), in which the fractured humeral head is modelled into a collar shape versus puzzle piece reconstruction (PPR) in elderly patients with complex proximal humeral fractures.

Materials And Methods: Between 2005 and 2011, we have performed 46 reverse shoulder prosthesis in patients with a mean age of 73.8 years (range 69-95) affected by shoulder complex fracture.

The classification of complex 4-part humeral fractures revisited: the missing fifth fragment and indications for surgery.

We describe a new classification of complex 4-part proximal humeral fractures (PHF). Its novelty lies in the involvement of fractures of the calcar area (i.e.

Minimum 25-year outcome and functional assessment of lumbar discectomy.

Study Design: A retrospective, follow-up cohort study.

Objective: To evaluate the 25-year (or longer) outcome of discectomy for lumbar disc herniation by validated instruments.

Summary Of Background Data: A comprehensive patient-oriented evaluation should include measurements of pain and disability along with a reliable evaluation of the general health status.
