Angioleiomyoma is a benign pericytic neoplasm with smooth muscle differentiation. Intra-articular angioleiomyoma is exceptionally rare with only four cases reported, all involving the knee joint. Here we report the first case of intra-articular angioleiomyoma entirely localized within the ankle joint. An 83-year-old male presented with progressively worsening ankle pain. Subsequent magnetic resonance imaging showed a soft tissue mass within the talocrural joint. Histologic examination and ancillary testing demonstrated fascicles of smooth muscle cells and interspersed, often compressed, vascular channels, consistent with an angioleiomyoma...

Rupture or avulsion of the distal triceps tendon is one of the least common tendon injuries. The most common clinical presentation of the injury is avulsion from the olecranon. The diagnosis of acute triceps tendon rupture may be missed and this can result in prolonged disability. We report the case of a 42-year-old man with isolated triceps rupture treated by an open surgical repair technique involving the use of bone suture anchors.

Scapular winging secondary to dorsal scapular nerve (DSN) damage is an underestimated condition. It is often caused by entrapment of the nerve due to a hypertrophic middle scalene muscle, or by stretching of the DSN during traumatic movements. The condition has also been attributed to myofascial pain syndrome of the rhomboids with entrapment of the DSN. The non-specific symptomatology reported by patients is often incorrectly diagnosed, and this can result in a high level of disability of the upper limb. A clinical case of misdiagnosed dorsal scapula entrapment is presented...

PURPOSE: the past decade has seen a considerable increase in the use of research models to study reverse total shoulder arthroplasty (RTSA). Nevertheless, none of these models has been shown to completely reflect real in vivo conditions. METHODS: we performed a systematic review of the literature matching the following key words: "reverse total shoulder arthroplasty" or "reverse total shoulder replacement" or "reverse total shoulder prosthesis" and "research models" or "biomechanical models" or "physical simulators" or "virtual simulators"...

Magnetic scaffolds are becoming increasingly attractive in tissue engineering, due to their ability to enhance bone tissue formation by attracting soluble factors, such as growth factors, hormones and polypeptides, directly to the implantation site, as well as their potential to improve the fixation and stability of the implant. Moreover, there is increasing evidence that the synergistic effects of magnetic scaffolds and magnetic fields can promote bone repair and regeneration. In this manuscript we review the recent innovations in bone tissue engineering that exploit magnetic biomaterials combined with static magnetic fields to enhance bone cell adhesion and proliferation, and thus bone tissue growth...

Massive rotator cuff tears are difficult to treat surgically due to retraction, degeneration and fraying of the ends of torn tendons, severe fatty infiltration and atrophy of the respective muscles. Procedures developed to close the gap between the rotator cuff and the greater tuberosity of the humerus, such as soft tissue release may be inadequate for large tears. Human or porcine dermal allografts still have uncertain benefits, and tendon transfers seem to be associated with poor outcomes, donor site morbidity and altered mechanics...

#12
Alessandro Ortolani, Roberto Bevoni, Alessandro Russo, Maurilio Marcacci, Mauro Girolami
Isolated posteromedial ankle dislocation is a rare condition thanks to the highly congruent anatomical configuration of the ankle mortise, in which the medial and lateral malleoli greatly reduce the rotational movement of the talus, and the strength of the ligaments higher than the malleoli affords protection against fractures. However, other factors, like medial malleolus hypoplasia, laxity of the ligaments, peroneal muscle weakness and previous ankle sprains, could predispose to pure dislocation. In the absence of such factors, only a complex high-energy trauma, with a rotational component, can lead to this event...

The sites where graft healing occurs within the bone tunnel and where the intra-articular ligamentization process takes place are the two most important sites of biological incorporation after anterior cruciate ligament (ACL) reconstruction, since they help to determine the mechanical behavior of the femur-ACL graft-tibia complex. Graft-tunnel healing is a complex process influenced by several factors, such as type of graft, preservation of remnants, bone quality, tunnel length and placement, fixation techniques and mechanical stress...

Alexander Scott North
The acromioclavicular (AC) joint is the articulation between the distal clavicle and the acromion process of the scapula. As the upper limb moves, passive motion of the AC joint occurs in three planes, with the AC and coracoclavicular ligaments providing stability. Injuries are common, particularly during contact sports, and are classified using Rockwood's system. Grade I (sprain) and II (rupture) injuries only affect the AC ligaments and are generally managed conservatively. However, recent reports have indicated that long-term outcomes after these injuries are poor, perhaps due to an inadequate period of immobilization preventing complete ligamentous healing...

Osteochondritis dissecans (OCD) is a rare yet fascinating disease affecting young, active patients. It remains a 'mysterious disease' whose etiopathology, still unclear, is the subject of ongoing studies aiming improving the knowledge of this condition and, therefore, treatment options, too. Even though the first descriptions of intra-articular loose bodies date back to very ancient times, it is only relatively recently that, thanks to the contribution of some very eminent physicians, it became recognized as a specific orthopaedic condition...

Knee extensor mechanism rupture is a serious complication of total knee arthroplasty (TKA). Its prevalence ranges from 1 to 10% and it is commonly observed as a chronic multifactorial pathology with the patellar tendon as the most common site of rupture. Knee extensor mechanism reconstruction can be performed using allogenic or synthetic grafts. In the literature it is still not clear whether one of these techniques is superior to the other and the choice is usually tailored to the patient case by case. Allografts allow better restoration of the anatomical landmarks, whereas the mesh technique is more reproducible and the graft does not elongate over time...

PURPOSE: historically, the original CLS Spotorno Stem has demonstrated excellent survival. The design of this stem was recently modified, resulting in the introduction of a shorter, modular version (CLS Brevius). The purpose of the current study was to evaluate the functional, radiological and survivorship outcomes of the cementless CLS Brevius Stem in a multi-surgeon, single center, consecutive series study at two years post-surgery. METHODS: the Authors performed 170 total hip arthroplasties in 155 patients using the shorter, triple-taper stem design (CLS Brevius)...
