Laparoscopic-assisted Resection of a Retroperitoneal Lumbar Nerve Root Neurofibroma: A Case Report.

We present a case of a 59-year-old patient with chronic low back pain, caused by a retroperitoneal intraneural tumour. Laparoscopic excision was performed and histology revealed a spinal nerve root neurofibroma. Post-operatively, the patient developed partial motor and sensitive deficits due to tumoral nerve entrapment, with progressive recovery with rehabilitation.

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.

Evaluation of the Davos self-assisted technique for reduction of anterior glenohumeral dislocations: a comparative study with the traction/countertraction technique.

Background: Few studies have compared conventional and self-assisted shoulder reduction maneuvers. The goal of this study was to evaluate the results of self-assisted Davos vs. traction/countertraction (T/Ct) techniques in the treatment of acute anterior shoulder dislocations.

Total calcanectomy in calcaneal osteomyelitis: An alternative to major amputation.

Background: Hindfoot ulcers associated with chronic calcaneus osteomyelitis are very difficult to manage and many patients need a limb amputation for resolution. Total calcanectomy can be a salvage procedure for these patients. The purpose of this study is to present our results of total calcanectomy.

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.

Glomus Tumor: "A-Not-So-Rare" Cause of Chronic Shoulder Pain-A Case Report and Literature Review.

Case: A 61-year-old male presented with chronic shoulder pain resistant to conservative treatment. Imaging identified a nodular lesion in the deltoid muscle, which histology after resection identified as a glomus tumor. After surgery, the patient became asymptomatic and at 4-year follow-up has not shown signs of recurrence.

"Bone-shot fracture" - An unusual iliac wing fracture caused by a projectile of autologous bone fragment. A case report.

Case: A young adult male sustained a high-energy crash suffering multiple injuries including a comminuted right femoral shaft fracture and an ipsilateral iliac wing fracture. The iliac fracture was caused by a femoral fragment which was projected and pierced the iliac wing. The patient underwent surgery with retrieval of the femoral fragment and fixation of the iliac and femoral fractures.

Why are tapes better than wires in knotless rotator cuff repairs? An evaluation of force, pressure and contact area in a tendon bone unit mechanical model.

Purpose: Knotless repairs have demonstrated encouraging performance regarding retear rate reduction, but literature aiming at identifying the specific variables responsible for these results is scarce and conflictive. The purpose of this paper was to evaluate the effect of the material (tape or wire suture) and medial tendon passage (single or double passage) on the contact force, pressure and area at the tendon bone interface in order to identify the key factors responsible for this repairs´ success.

Methods: A specific knotless transosseous equivalent cuff repair was simulated using 2 tape or suture wire loaded medial anchors and 2 lateral anchors, with controlled lateral suture limb tension.

Lateralized versus nonlateralized glenospheres in reverse shoulder arthroplasty: a systematic review with meta-analysis.

Hypothesis/background: Lateralization in reverse shoulder arthroplasty (L-RSA) was proposed to overcome some limitations of the original Grammont-style design (S-RSA). This systematic review aims to compare the clinical and functional outcomes and complications of S-RSA with L-RSA, and to assess the individual results of metallic and bony lateralization implants.

Methods: A systematic search from January 1980 to December 2019 was performed.

Neuroimmune expression in hip osteoarthritis: a systematic review.

Background: Neuroimmune axis is central in the physiopathology of hip osteoarthritis (OA), but its specific pathways are still unclear. This systematic review aims to assess the nervous and immune system profile of patients with hip osteoarthritis (OA) when compared to healthy controls.

Methods: A systematic review followed PRISMA guidelines was conducted.

Fracture pain-Traveling unknown pathways.

An increase of fracture incidence is expected for the next decades, mostly due to the undeniable increase of osteoporotic fractures, associated with the rapid population ageing. The rise in sports-related fractures affecting the young and active population also contributes to this increased fracture incidence, and further amplifies the economical burden of fractures. Fracture often results in severe pain, which is a primary symptom to be treated, not only to guarantee individual's wellbeing, but also because an efficient management of fracture pain is mandatory to ensure proper bone healing.

Reverse shoulder arthroplasty for the treatment of nonunions of the surgical neck of the proximal part of the humerus (type-3 fracture sequelae).

Background: Fracture sequelae of the proximal part of the humerus are challenging conditions, and various treatment options have been described. The purpose of this multicenter study was to analyze the clinical and radiographic outcomes as well as the complications following semiconstrained reverse total shoulder arthroplasty for the treatment of nonunion of a surgical neck fracture of the proximal part of the humerus.

Methods: Thirty-two patients with a mean age of sixty-eight years (range, forty-eight to eighty-three years) managed with a reverse shoulder arthroplasty for the treatment of nonunion of a proximal humeral fracture were analyzed clinically and radiographically.

[Post Traumatic Pseudoaneurysm of the Axillary Artery with Late Clinical Presentation].

Traumatic lesions of the axillary artery are rare in fractures of the proximal humerus. Clinical manifestations are sparse, generally presenting in the acute form, although in some cases the clinical signs only emerge later after the traumatic event. The early diagnosis might prevent serious complications.

Epithelioid hemangioendothelioma presenting as a vertebral fracture.

Epithelioid hemagioendothelioma (EH) is a rare vascular tumor with an intermediate biological behavior between hemangioma and angiosarcoma. Vertebral location is even more rare, and because the number of reported cases of EH is small and the follow-up periods short, the best surgical treatment, the role of radiotherapy and chemotherapy, as well as the definitive prognosis are still not established. The authors report a case of EH which presented as a vertebral fracture with neurological impairment, where a percutaneous biopsy was inconclusive.

[New perspectives on degenerative disease treatment].

The degenerative disc disease (DDD) is a chronic and multifactorial condition of the intervertebral disc that can manifest itself by axial pain, radiculopathy, myelopathy and spinal stenosis. It constitutes an increasing cause of lumbar pain and morbidity in Western Societies, with important socio-economic implications. The available treatment options do not modify the intervertebral disc degeneration process and they are not always capable of relieving symptoms.
