Introduction Complex fractures of the proximal humerus with splitting-head component and metaphyseal propagation are very rare injuries that are difficult to treat. Preservation of the humeral head is always considered except in cases with severe comminution and compromised vascularity where shoulder hemiarthroplasty is an alternative option. Case...

Background: The distal end of the clavicle accounts for 10-28% of all clavicle fractures of which 52.8% are considered displaced and require internal fixation due to their high percentage of non-union. Numerous surgical techniques have been described for the well-known Neer types IIA, IIB, and V. Still, the literature is scarce for the rare "extra...

Traumatic brachial plexus injuries are serious, life-changing injuries that are becoming more common worldwide. A thorough physical examination, as well as radiologic and electrodiagnostic tests, are all part of the initial evaluation. Parameters such as injury patterns, the timing of intervention, patients' expectations, and pre-injury functional...

Background Knee osteoarthritis is a disease linked to severe pain and disability and several methods have been used to aid alleviate its symptoms, with varying degrees of success. Cooled radiofrequency ablation (CRFA) and cryoneurolysis (CRYON) are two novel methods under investigation for their capacity to control pain in knee osteoarthritis, whil...

Background Hip fractures are an increasingly common injury among older people who usually experience significantly worse mobility, independence in function, health, quality of life, and high rates of institutionalization. Studies have shown that only 40-60% of participants recover their pre-fracture level of mobility and ability to perform instrume...

Menisci are involved in providing shock absorption, knee stability, and load transfer. Age, tear pattern, location, size and extent, repair time and technique, and patient habits are among various factors that affect meniscal healing. Meniscus repair has become the procedure of choice for the treatment of meniscal tears. However, treatment of menis...

Introduction Failure after operative treatment of complex proximal humeral fractures (PHF) can prove challenging even for experienced surgeons. Reverse shoulder arthroplasty (RSA) seems to offer a satisfactory revision procedure with good clinical outcomes. Materials and Methods We present a case series of 14 patients, who were treated during a 3....
Article
Full-text available
Introduction Treatment of intra-articular fractures of the distal humerus is challenging due to their complexity, comminution, and associated complications. The evolution of surgical approaches and the design of elbow-specific implants over the last decades have failed to improve clinical and radiological outcomes. Studies are sparse regarding the...

Introduction To date, the proper choice of graft for anterior cruciate ligament (ACL) reconstruction remains a matter of conflict. We aimed to compare the clinical and functional outcomes of the two most commonly utilized autografts, bone-patella tendon-bone (BPTB) and four-strand hamstring tendon (HT) graft, at 6 and 12 months after surgery. Metho...

Numerous studies have focused on determining the optimal choice between the two most used anterior cruciate ligament (ACL) reconstruction autografts. In order to address this matter, we performed a systematic review of every meta-analysis published on the PubMed platform between 2001 and 2020, comparing the functional outcomes, the static stability...

BACKGROUND Chronic posterior knee dislocation after total knee arthroplasty (TKA) is a rare but serious complication, especially when it coexists with septic implant loosening, flexion contracture, and extensive comorbidities. Although the severity is comparable to that in the native knee dislocation, there are few reports in the literature. When T...

Bilateral Galeazzi fracture-dislocations are extremely rare injuries and only a few case reports have been described so far in the literature. Herein, we report the case of a 31-year-old bicyclist who sustained bilateral Galeazzi fracture-dislocations after a collision with a car. Both radial shaft fractures were simple (AO type 22-A2.3), at the sa...

Case report: Fractures of the talus in adolescents are uncommon and usually involve the talar body or neck. We report a rare fracture of the entire posterior talar process in a 14-year-old boy who fell during skateboarding. He was managed with open reduction and fixation with a headless screw. He gradually regained sports activities after 4 months...
Article
Full-text available
Background The optimal technique for the displaced greater tuberosity (GT) fractures remains unclear; those in favor of arthroscopic techniques emphasize on the feasibility of arthroscopic reduction and fixation, while others report that anatomic reduction and osteosynthesis of the fracture are optimal through open surgery. Therefore, we performed...
Article
Full-text available
Background Unstable ‘extra-lateral’ fractures of the distal clavicle (lateral to the coracoclavicular ligaments) are not distinguished in the Neer classification system and are commonly included with Neer IIb fractures. In the literature, there is no optimal surgical technique for managing unstable fractures of the distal clavicle, nonetheless for...
