Is combined MPFL reconstruction and tubercule tibial osteotomy superior to isolated reconstruction? A systematic review and meta-analysis.

Purpose: There is no consensus for management of patellar instability, even in the case of malalignment. The purpose of the review is to evaluate outcomes in the literature of MPFL reconstruction with and without tibial tubercle osteotomy.

Methods: Two databases PubMed and Scopus were searched for studies comparing MPFL reconstruction with and without concomitant tibial tuberosity osteotomy.

Ulnar-Sided Upper Extremity Traumatic Wounds: What Should We Expect to Find?

Upper limb traumatic injuries have a significant impact on social and professional life; however, there is still a paucity of studies focusing on the injuries of the ulnar border of the forearm, wrist and hand. We designed a retrospective single-blinded study, including all patients with deep traumatic wounds affecting the ulnar side of the forearm, wrist or hand, that received surgical treatment from 2006 until 2016. A characterisation of the sample, assessment of concomitant injuries and clinical outcomes, as well as neurological and functional evaluation were performed.

Superior Gluteal Nerve Anatomy and Its Injuries: Aiming for a More Secure Surgical Approach of the Pelvic Region.

Because most of the recognized causes of superior gluteal nerve (SGN) injury are iatrogenic, detailed knowledge of the anatomy of the SGN is crucial to prevent its injury associated with surgical procedures. This study aims to describe the precise location of SGN or its branches at the greater sciatic foramen, measure the distances of these neural structures to palpable bony landmarks, and evaluate the possible correlation between these parameters and pelvis size. Twenty human cadaveric hemipelvises were studied.

The Surgical Vascular Anatomy of the Lower Lumbar Arteries and Its Implications in Minimally Invasive Spine Surgery: A Cadaveric Study.

Background: Minimally invasive lateral lumbar interbody fusion is a technique that has become increasingly popular for the treatment of degenerative lumbar spine disease; however, the pertinent surgical vascular anatomy has not been examined in detail. The goal of this study is to examine the anatomy of the lower lumbar and median sacral arteries, which are important determinants of these surgical outcomes.

Methods: This is an observational, experimental study based on cadaveric models, including 20 embalmed adult human cadavers.

Proximal humerus fractures: epidemiology and trends in surgical management of hospital-admitted patients in Portugal.

Background: Proximal humerus fractures (PHFs) are frequent and associated with significant health care burden. National epidemiological data are limited. Our objective is to characterize the Portuguese population admitted with PHFs and analyze therapeutic management, the impact of associated lesions, and mortality rate.

Arthroscopic Anatomical Acromioclavicular Joint Reconstruction using a Button Device and a Semitendinosus Graft.

Objective: To report a new technique for anatomical acromioclavicular (AC) joint reconstruction.

Methods: In order to minimize such complications, the authors describe a new anatomical and biological AC joint repair. This technique aims to provide greater stability by using two anatomically placed clavicular tunnels and a combined construct with a double endobutton cortical fixation for primary stabilization, and to be biologically advantageous by using an autologous semitendinosus (ST) tendon graft.

Pseudo-patella baja after total knee arthroplasty: Radiological evaluation and clinical repercussion.

Background: Anterior knee pain is an important complication after total knee arthroplasty (TKA). One possible contributor is the elevation of the joint line, known as pseudo-patella baja (PPB). Limited research has been conducted regarding this condition impacting TKA management.

A Technique for a More Accurate Acromioclavicular Joint Reduction in Arthroscopic Coracoclavicular Stabilization of Acromioclavicular Joint Dislocation.

Loss of reduction is the most common complication following acromioclavicular dislocations treatment, with literature showing greater postoperative coracoclavicular distances associated with worse clinical results. We present a surgical gesture that aims to help surgeons achieve and secure an anatomic acromioclavicular reduction during coracoclavicular fixation. This technique has the possibility to improve radiological and functional results of acromioclavicular dislocation treatment.

Muscular Cysticercosis: An Incidental Finding in the Developed World.

Case: We present a case of muscular cysticercosis incidentally diagnosed in a patient admitted for a femoral neck fracture and submitted to total hip arthroplasty.

Conclusion: Human cysticercosis is a parasitic infection representing a major health concern in developing countries. The clinical features are variable and depend on the anatomic location, cyst burden, cysticerci stage, and host inflammatory response.

Distal Biceps Reconstruction With an Alternative Technique for Tendon Tensioning and Fixation: A Case Report.

Case: A 41-year-old right-handed male patient presented to our institution with a chronic distal biceps rupture after failed primary surgery 6 months previously. We performed a reconstruction with semitendinosus autograft fixed proximally with a Pulvertaft weave and distally with a cortical button plus interference screw. The patient showed complete pain resolution and excellent functional results.

Deep gluteal space anatomy and its relationship with deep gluteal pain syndromes.

Introduction: Increasing interest has been seen in understanding the anatomy and biomechanics involved in the Deep Gluteal Syndrome, therefore the main objective of our paper was to define the anatomy of the deep gluteal space concerning the important osseous, muscular and neurological structures.

Methods: 12 cadaveric models (24 hemipelvises) were used. We proceeded with classical anatomic dissection and evaluated numerous osseous, musculotendinous and neurologic structures and their relationships.

Coracohumeral distance and coracoid overlap as predictors of subscapularis and long head of the biceps injuries.

Background: Subscapularis (SS) lesions are often underdiagnosed because of an incomplete understanding of contributing factors but also because of a greater difficulty in SS tear diagnosis with magnetic resonance imaging or physical examination. In this setting, predicting factors can be useful tools in these injuries' management. The goal of this study was to determine the influence of the coracohumeral distance (CHD) and coracoid overlap (CO) in anterior rotator cuff lesions, as well as to determine the CHD and CO values that can accurately predict SS and long head of the biceps (LHB) injuries.
