Morphometric anatomical and CT study of the human adult sacroiliac region.

Purpose: To identify and describe the morphometry and CT features of the articular and extra-articular portions of the sacroiliac region. The resulting knowledge might help to avoid complications in sacroiliac joint (SIJ) fusion.

Methods: We analyzed 102 dry hemi-sacra, 80 ilia, and 10 intact pelves and assessed the pelvic computerized tomography (CT) scans of 90 patients, who underwent the examination for conditions not involving the pelvis.

Lumbar Interspinous Process Fixation and Fusion with Stand-Alone Interlaminar Lumbar Instrumented Fusion Implant in Patients with Degenerative Spondylolisthesis Undergoing Decompression for Spinal Stenosis.

Study Design: Prospective cohort study.

Purpose: To assess the ability of a stand-alone lumbar interspinous implant (interspinous/interlaminar lumbar instrumented fusion, ILIF) associated with bone grafting to promote posterior spine fusion in degenerative spondylolisthesis (DS) with vertebral instability.

Overview Of Literature: A few studies, using bilateral laminotomy (BL) or bilateral decompression by unilateral laminotomy (BDUL), found satisfactory results in stenotic patients with decompression alone, but others reported increased olisthesis, or subsequent need for fusion in DS with or without dynamic instability.

Ossification of the Interosseous Membrane of the Leg in a Football Player: Case Report and Review of the Literature.

Introduction. We report a case of ossification of the interosseous membrane (OIM) of the leg in a football player who had no history of severe local traumas. A review of the literature of the OIM of the leg in athletes was also carried out.

Reverse shoulder prosthesis in patients with rheumatoid arthritis: a systematic review.

Purpose: To obtain detailed information on the outcomes of patients with rheumatoid arthritis (RA) undergoing reverse shoulder arthroplasty (RSA) METHODS: A literature search was conducted for studies reporting on the use of RSA in RA patients from 1990 to 2014. The inclusion criteria were a report of sufficient information on pre-operative status and surgical outcome allowing evaluation of the therapeutic potential of RSA in RA. The literature search resulted in 586 hits, but only five studies that met the inclusion criteria were assessed.

Kinematic analysis of reaching movements of the upper limb after total or reverse shoulder arthroplasty.

Studies have analyzed three-dimensional complex motion of the shoulder in healthy subjects or patients undergoing total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA). No study to date has assessed the reaching movements in patients with TSA or RSA. Twelve patients with TSA (Group A) and 12 with RSA (Group B) underwent kinematic analysis of reaching movements directed at four targets.

Assessment of patient's pain-related behavior at physical examination may allow diagnosis of recent osteoporotic vertebral fracture.

Background Context: Although innumerable studies have analyzed the multiple aspects of osteoporotic vertebral fractures, no study has focused on the clinical features related to spine pain in patients with recent osteoporotic vertebral compression fractures (VCFs).

Purpose: To determine whether the assessment of pain-related behavior (P-RB) of patients with osteoporotic VCFs of recent onset may allow the fracture to be strongly suspected, or even diagnosed, at physical examination.

Study Design: Pain-related behavior of elderly patients attending an outpatient spine clinic was evaluated on the basis of six consecutive movements made on the examining table.

Conversion of shoulder arthroplasty to reverse implants: clinical and radiological results using a modular system.

Purpose: Revision of a shoulder arthroplasty to a reverse arthroplasty is a highly demanding procedure. The aim of this study is to report the clinical results of hemi and total shoulder prosthesis revisions to reverse implants without removal of the humeral stem, using a modular shoulder replacement system (SMR Lima LTD). We retrospectively reviewed 26 patients who underwent an operation from 2004 to 2009.

Injury to major abdominal vessels during posterior lumbar interbody fusion. A case report and review of the literature.

Background Context: Numerous cases of injury to major abdominal vessels during the excision of a lumbar herniated disc have been reported, but no cases of injury during interbody fusion by a posterior approach have been described.

Purpose: To report on an injury to common iliac vessels during a posterior lumbar interbody fusion (PLIF) and discuss the causes and possible preventive measures.

Study Design: A unique case report and a review of the literature.

The possible role of the transcription factor nuclear factor-κB on evolution of rotator cuff tear and on mechanisms of cuff tendon healing.

Background: We verified if the nuclear factor-κB (NF-κB) was present on the margins of rotator cuff tears (RCTs). Because NF-κB regulates apoptosis and stimulates neoangiogenesis, we hypothesized that NF-κB has a role in the evolution of RCT and in possible mechanisms of RCT healing.

Materials And Methods: Samples from tear margins, subacromial bursa, and healthy subscapular tendons were excised during arthroscopic treatment of patients with posterosuperior RCT.

Use of platelet-leukocyte membrane in arthroscopic repair of large rotator cuff tears: a prospective randomized study.

Background: Arthroscopic rotator cuff repair generally provides satisfactory results including decreased shoulder pain and improved shoulder motion. Unfortunately, imaging studies demonstrate that the retear rate associated with the available arthroscopic techniques may be high. The purpose of this study was to evaluate the clinical and magnetic resonance imaging (MRI) results of arthroscopic rotator cuff repair with and without the use of platelet-leukocyte membrane in patients with a large posterosuperior rotator cuff tear.

The association between arterial hypertension and rotator cuff tear: the influence on rotator cuff tear sizes.

Background: This study was conducted to establish whether hypertension increases the risk of occurrence of rotator cuff tear and influences its size.

Materials And Methods: A case-control design was used. We studied 408 consecutive patients (228 men, 180 women) who underwent arthroscopic rotator cuff repair.

The relationship between acromion thickness and body habitus: practical implications in subacromial decompression procedures.

To define the bone's amount that should be removed during an acromioplasty has always been a challenge. We aimed to verify the correlations between scapular dimensions and acromial thickness, assess the differences between the two genders, investigate the relationship between acromial type and thickness. We examined 500 dried scapulae, measuring the major axis of the scapular body and the acromial thickness; these were also catalogued according to gender.

Total shoulder arthroplasty for the treatment of failed hemiarthroplasty in patients with fracture of the proximal humerus.

Background: Little information is available for the outcomes of conversion to total shoulder arthroplasty (TSA) of failed hemiarthroplasty (HA) implanted for fractures or fracture-dislocations of the proximal humerus.

Materials And Methods: We evaluated the clinical and radiographic results in 16 patients who underwent conversion of HA to TSA due to pain and shoulder disfunction. Patients were a mean age of 63 years at revision, which was occurred a mean of 3.

Comparison between two classifications of humeral head fractures: Neer and AO-ASIF.

Our purpose was to verify if the Neer and AO-ASIF classifications for fractures of the proximal humerus satisfy the requisites of simplicity and reproducibility and if the parameters that they consider to establish the severity of the fracture are similar. Two of the authors classified the proximal humeral fractures of 227 patients based on plain radiographs, and they repeated the classification five years later. The reliability, reproducibility and coherence of the classifications were investigated.

Percutaneous pinning of three- or four-part fractures of the proximal humerus in elderly patients in poor general condition: MIROS® versus traditional pinning.

Purpose: Elderly subjects often have fractures of the proximal humerus, which may be difficult to manage in patients in poor general condition. The MIROS is a new percutaneous pinning device allowing correction of angular displacement and stable fixation of fracture fragments. We evaluated the results of percutaneous fixation of three- or four-part fractures of the proximal humerus of patients in the American Society of Anesthesiologists physical status three or four treated either with MIROS or traditional percutaneous pinning (TPP).

Open debridement and radiocapitellar replacement in primary and post-traumatic arthritis of the elbow: a multicenter study.

Background: Postmortem and clinical studies have shown an early and prevalent involvement of the radiohumeral joint in primary and secondary arthritis of the elbow. The lateral resurfacing elbow (LRE) prosthesis has recently been developed for the treatment of lateral elbow arthritis. However, few data have been published on LRE results.

Aperius interspinous implant versus open surgical decompression in lumbar spinal stenosis.

Background Context: Few studies have analyzed the results of an interspinous distraction device in patients with lumbar spinal stenosis. It is still unknown whether the outcomes of an interspinous implant are related to the severity of stenosis.

Purpose: To determine the success rate of the Aperius implant and open decompression with the aim of defining better the indications for the two modalities of treatment.

Complex fracture-dislocations of the proximal ulna and radius in adults: a comprehensive classification.

Background: Complex fracture-dislocations of the proximal ulna and radius include multiple anatomic lesions, the management of which is known to be demanding. Although several classifications have been proposed, none appear to be exhaustive, and most of them have neither therapeutic nor prognostic value. The purpose of this study was to design a comprehensive classification that may provide a guide for the operative management of these injuries.

The impact of preoperative smoking habit on rotator cuff tear: cigarette smoking influences rotator cuff tear sizes.

Hypothesis: Smoking is an important risk factor for the development of rotator cuff tears. We hypothesized that smoking may also influence rotator cuff tear size.

Materials And Methods: The study included 408 patients who underwent arthroscopic repair of cuff tear.

The safe zone for avoiding suprascapular nerve injury during shoulder arthroscopy: an anatomical study on 500 dry scapulae.

Hypothesis/background: Suprascapular nerve injury may be a complication during shoulder arthroscopy. Our aim was to verify the reliability of the existing data, assess the differences between scapulae in the 2 genders and in the same subject, obtain a safe zone useful to avoid iatrogenic nerve lesions, and analyze the existing correlations between the scapular dimensions and the safe zone.

Methods: We examined 500 dried scapulae, measuring 6 distances for each one, referring to the scapular body, glenoid, and the course of the suprascapular nerve, also catalogued according to gender and side.

Shoulder adhesive capsulitis in the early freezing phase: correlations between blood exams and Constant Score.

We analysed the possibility that some blood values could be considered as a prognostic index of shoulder adhesive capsulitis. Fifty-six conservatively treated patients were clinically evaluated and prospectively followed at the moment of their freezing phase. At the beginning of the disease (time 0) and after 4 months (time 1), we registered some blood parameters values and their Constant Score (CS).

Rupture of the long head biceps tendon treated with tenodesis to the coracoid process. Results at more than 30 years.

We evaluated patients at very long term with rupture of the long head biceps tendon (LHBT) in whom the tendon stump had been sutured to the coracoid tip (Gilcreest technique). Our aim was to determine the natural history of shoulders deprived of the LHBT and to assess the validity of the surgical technique. Between 1969 and 1981, 30 patients with rupture of the LHBT and no evidence of cuff tear underwent the Gilcreest operation.

Management of complex elbow instability.

Complex elbow instability is a challenging injury even for expert elbow surgeons. The preoperative radiographs should be carefully evaluated to recognize all lesions that may occur in complex elbow instabilities. Recognizing all the possible lesions is critical to achieve an optimal outcome.

Open reduction and internal fixation combined with hinged elbow fixator in capitellum and trochlea fractures.

Background And Purpose: The current surgical treatment for displaced fracture of the capitellum and trochlea is open reduction and internal fixation (ORIF), but the results are often unsatisfactory, particularly with complex fractures. Furthermore, the surgical approach, the kind of osteosynthesis, and postoperative management are controversial. We evaluated the results of internal fixation combined with hinged external fixation.

The relationship between chronic type III acromioclavicular joint dislocation and cervical spine pain.

Background: This study was aimed at evaluating whether or not patients with chronic type III acromioclavicular dislocation develop cervical spine pain and degenerative changes more frequently than normal subjects.

Methods: The cervical spine of 34 patients with chronic type III AC dislocation was radiographically evaluated. Osteophytosis presence was registered and the narrowing of the intervertebral disc and cervical lordosis were evaluated.
