RESUMEN
INTRODUCTION: Scapular body fractures represent less than 1% of all skeletal fractures. Operative criteria and risk factors for scapular fracture instability are well defined. Non-operative management of scapular body fractures show satisfactory results but with shortening and medialization of the scapular body. The aim of this study is to evaluate if surgical treatment will result in an improved quality of life and shoulder function compared to non-operative treatment on patients suffering from a scapular body fracture. MATERIALS AND METHODS: From a total of 381 retrospectively identified scapular body fractures, we included 45 patients. The enrolled patients were divided into two groups: the surgical treatment (ST, n = 20) group and the non-operative treatment (NOT, n = 25) group. The Non-Union Scoring System (NUSS) was used to assess bone healing on radiographs. The functional evaluation of the two groups during the follow-up were performed using the Constant Shoulder Score (CSS) and the Quick Disabilities of the Arm, Shoulder and Hand Score (QuickDASH). Complications, reoperation rates, and time until bony union were also documented. The minimum follow-up for this study was designated as 12 months. RESULTS: The ST group had better mean CSS and QuickDASH scores compared to the NOT group at 1, 3 and 6 months of follow-up. No statistically significant difference was detected at 12 months follow-up. ST group also demonstrated improved results in time until bone union, reduction of rehabilitation time, complications and return to work rates. CONCLUSION: This study suggests that surgical treatment for extraarticular scapular fractures can achieve better short-term functional outcomes (3 to 6 months) compared to conservative treatment.

BACKGROUND AND AIM OF THE WORK: The reverse shoulder arthroplasty (RSA) has risen exponentially, this has entailed an increasing number of complications and reoperations. In RSA, loads are transferred directly to the glenoid component. As a result, failure of the glenoid component is one of the most common complications. CT 3D preoperative planning, patient-specific and the possibility of performing a more precise and controlled surgical gesture in the operating room are increasingly important. The use of the GPS navigation on CT 3D planning has proved to be useful above all in terms of accuracy, reliability and the possibility of reproducing the planned gesture preoperatively. METHODS: This study analyzes the precision, safety, and reproducibility of the GPS system for the reverse shoulder prosthesis tested on 6 scapulohumeral cadaver specimens, subsequently subjected to anatomical dissection to verify the correct positioning of the glenoidcomponents and the percentage of appropriateness in the field of planning previously virtually assumed. RESULTS: Postoperative macroscopic dissection revealed no central peg perforated or screws malpositioned, no leaking from the bone or injury to the adjacent neurovascular structures. The average length of the screws was 42 mm (range 36 mm to 46 mm) for the lower screw and 40 mm for the upper one (range 36 mm to 42 mm). CONCLUSIONS: This cadaver study has shown that GPS navigation offers greater efficiency in baseplate and screws placement and can avoid intra- and postoperative complications.

A posterior tibial tendon (PTT) rupture associated with ankle fractures is a very rare condition. Ankle pronation and external rotation (PER) movement are the typical traumatic mechanism. This injury is frequently overlooked preoperatively. Early diagnosis and treatment are very important to prevent the serious consequences related to functional PTT insufficiency on biomechanics of the foot. Few cases have been described in the literature that highlight the relationship between PTT rupture and PER type ankle fracture with a medial malleolar fracture. We present a case of a complete PTT rupture in a closed atypical ankle fracture in which a medial malleolar fracture was associated with a very large fragment from the anterolateral distal tibia (Tillaux-Chaput fragment) and a concomitant avulsion fracture from the anteromedial portion of the fibula (Lefort-Wagstaffe fragment), with a novel pattern never described before.

Reverse total shoulder arthroplasty (RSA) successfully restores shoulder function in different conditions. Glenoid baseplate fixation and positioning seem to be the most important factors influencing RSA survival. When scapular anatomy is distorted (eccentric osteoarthrirtis, rotator cuff arthropathy), optimal baseplate positioning and secure screw purchase can be challenging. The aim of this study was to evaluate whether CT-based pre-operative planning, integrated with intra-operative navigation could improve glenoid baseplate fixation and positioning by increasing screw length, reducing number of screws required to obtain fixation and increasing the use of augmented baseplate to gain the desired positioning. Twenty patients who underwent navigated RSA were compared retrospectively with 20 patients operated on with a conventional technique. All the procedures were performed by the same surgeon, using the same implant. Mean screw length was significantly longer in the navigation group (35.5 ± 4.4 mm vs 29.9 ± 3.6 mm; p = .001). Significant higher rate of optimal fixation using 2 screws only (17 vs 3 cases, p = .019) and higher rate of augmented baseplate usage (13 vs 4 cases, p = .009) was also present in the navigation group. Pre-operative CT-based planning integrated with intra-operative navigation can improve glenoid component positioning and fixation, possibly leading to an improvement of RSA survival.
RESUMEN
INTRODUCTION: NeuroEndocrine Neoplasms (NENs) are rare and can originate from any epithelial organ. We describe a very rare case of retroperitoneal metastasis from a non-functioning neuroendocrine tumor of the ethmoid region and focus on the various issues related to NENs, from their nosological classification up to the most recent acquisitions in the diagnostic and therapeutic field. PRESENTATION OF CASE: A woman presented with a mass in the right retroperitoneal area that infiltrated liver and kidney. The anamnestic data showed a previous undifferentiated small cell tumor of the left ethmoid-nasal-orbital region. The mass was removed surgically and the definitive histological examination revealed a non-functioning undifferentiated malignant small cell neoplasm. DISCUSSION: NENs represent a chapter of oncology whose systematization remains difficult. The lack of hormonal syndrome in Biologically Inactive Neuroendocrine Tumors (BINTs) may delay the diagnosis. Clinical manifestations relate to the size and location of the neoplasm. Small cell NeuroEndocrine Carcinoma (NEC) of the ethmoid-nose-orbital region is an extremely rare occurrence and generally the most frequent metastatic localization is represented by the larynx. CONCLUSION: This case highlights the contradictions typical of NENs and only new scientific acquisitions in the histopathological field can help us in the future. Surgery remains the only possibility of treatment and diagnosis of large masses of inactive NENs. This is the only case in the world of metastasis from NEC of the nose-orbital region in the retroperitoneum.
RESUMEN
INTRODUCTION: SANT of the spleen is a benign lesion that does not recur after splenectomy with unknown etiology. PRESENTATION OF THE CASE: We report a case of sclerosing angiomatoid nodular transformation (SANT) of the spleen mimicking a splenic abscess in a patient with imaging studies that failed to differentiate this lesion from other splenic lesions. DISCUSSION: SANT of the spleen is a rare condition, with only less than 100 cases reported in the literature. Clinically, SANT is only a kind of described pathological diagnostic conception. As in our case, these splenic lesions are often incidental findings on imaging studies performed for other reasons. CONCLUSION: The patient was treated with splenectomy, which has proved to be both diagnostic and therapeutic. Although histology can lead to the diagnosis of vascular tumor, immunohistochemistry is the only way to confirm the diagnosis.
RESUMEN
The authors present a case of midgut perforated diverticulitis in a 78-year-old patient, associated with a colovesical fistula and sigmoid obstruction of diverticular origin. Surgical resection of the small bowel segment affected together with primary anastomosis is the preferred treatment in patients with symptomatic complicated jejunoileal diverticular disease. In complicated midgut diverticulitis the preoperative diagnosis is a challenge: the symptoms are aspecific and imaging techniques are of no use. As a result, the diagnosis of complicated jejunoileal diverticulitis can be quite difficult, and a definitive diagnosis may often be made only after surgical exploration.
