Imaging of Usual and Unusual Complication of Rotator Cuff Repair

Domenico Albano et al. J Comput Assist Tomogr. 2019 May/Jun.

Abstract

Several complications may be encountered after rotator cuff (RC) repair. A thorough knowledge of surgical interventions, normal postoperative findings, and postoperative complications is crucial to provide a timely diagnosis, improving the clinical outcome of patients. Postoperative complications may involve RC, implanted device, osteochondral tissue, surgical-site infection, peripheral nerves, soft tissues, and vascular structures. In this review, we discuss the usual and unusual complications detectable after RC repair.

Consequences on aging process and human wellness of generation of nitrogen and oxygen species during strenuous exercise

Francesco Sessa et al. Aging Male. 2020 Mar.

Abstract

Impairment of antioxidant defense system and increase in metabolic rate and production of reactive oxygen species have been demonstrated in strenuous exercise. Both at rest and during contractile activity, skeletal muscle generates a very complex set of reactive nitrogen and oxygen species; the main generated are superoxide and nitric oxide. The nature of the contractile activity influences the pattern and the magnitude of this reactive oxygen and nitrogen species (ROS) generation. The intracellular pro-oxidant/antioxidant homeostasis undergoes alteration owing to strenuous exercise and the major identified sources of intracellular free radical generation during physical activity are the mitochondrial electron transport chain, polymorphoneutrophil, and xanthine oxidase. Reactive oxygen species increased tissue susceptibility to oxidative damage and pose a serious threat to the cellular antioxidant defense system. The possible dangerous consequences of the aging process and human wellness are emphasized in this review.

Bankart Repair With Subscapularis Augmentation in Athletes With Shoulder Hyperlaxity

Marco Maiotti et al. Arthroscopy. 2021 Jul.

Abstract

Purpose: The purpose of this study was to demonstrate that arthroscopic Bankart repair with associated arthroscopic subscapularis augmentation (ASA) could be a valid surgical option in the treatment of anterior shoulder instability, in collision and contact sports athletes, affected by shoulder hyperlaxity.

Methods: In total, 591 arthroscopic Bankart repairs plus ASA were performed in 6 shoulder centers from 2009 to 2017. Inclusion criteria were the following: collision and contact sports activities, recurrent anterior instability associated with hyperlaxity and glenoid bone loss (GBL) < 15%. Exclusion criteria were GBL > 15%, voluntary instability, multidirectional instability, pre-existing osteoarthritis and throwing athletes. The minimum follow-up was 24 months. Hyperlaxity was clinically evaluated according to Neer and Coudane-Walch tests. Before surgery, all patients underwent magnetic resonance imaging and computed tomography scanning. Pico area method was used to assess the percentage of GBL. Patients were operated on by 6 surgeons, and their functional outcomes were evaluated by 2 independent observers. The Western Ontario Shoulder Instability Index (WOSI), Rowe, American Shoulder and Elbow Surgeons (ASES) scores were used to assess results.

Results: Overall, 397 patients with evidence of shoulder hyperlaxity (positive sulcus sign in ER1 position and Coudane-Walch test > 85°) met all inclusion criteria. The mean WOSI score was 321; the mean Rowe score rose from 68.5 to 92.5 (P = .037), and the ASES score rose from 71.5 to 97.4 (P = .041). Seven patients (1.6%) had atraumatic redislocation, and 9 patients (2.2%) had post-traumatic redislocation. At final follow-up the mean functional deficit of external rotation was 15° with the arm in adduction (ER1 position) and 10° in abduction (ER2 position).

Conclusions: The Bankart repair plus ASA has been demonstrated to be safe and effective for restoring joint stability in patients practicing collision and contact sports or affected by chronic anterior shoulder instability associated with GBL (<15%) and hyperlaxity, without compromising external rotation.

Level of evidence: Level IV, case series.

Osteochondral allograft transplantation for complex distal humeral fractures assisted by 3D computer planning and printing technology: technical note

Raffaele Russo et al. Eur J Orthop Surg Traumatol. 2022 Oct.

Abstract

Purpose: The surgical treatment of comminuted distal humeral articular fractures (DHF) is challenging and is jeopardized by the high rate of complications. The study aims to describe the application of osteochondral allograft (OCA) transplantation for the treatment of complex DHF assisted with a 3D printed specific instrumentation.

Methods: Retrospective study. Inclusion criteria were the presence of an articular multi-fragmented DHF treated with frozen OCA. Clinical, self-reported and radiographic outcomes were collected every 6 months. CT were performed at 2 years FU.

Results: Four patients were included. At a mean follow-up of 37.3 months (24-49) MEPS, DASH and VAS were 90 (80-100), 11.8 (0-25) and 1 (0-3) points, respectively. Not significant complication or reoperation was recorded. Graft healing was observed in 3 cases. In all cases, we observed arthritic progression after 2 years of follow-up.

Conclusion: OCA transplantation can be considered a reliable and safe procedure in patients affected by a complex DHF.

Use of 3D Planning and Patient-specific Guides for Proximal Humerus Corrective Osteotomy Associated With Shoulder Prosthesis Implantation in Proximal Humeral Varus Malunion

Raffaele Russo et al. Tech Hand Up Extrem Surg. .

Abstract

Humeral stem prosthesis implantation in case of proximal humerus varus malunion (type 1D fracture sequelae) is often complicated by greater tuberosity fracture and by posterosuperior rotator cuff iatrogenic damage. Moreover, the varus malunited humeral head could lead to scapular impingement and reduce the range of motion. To address this problem, we introduced a new surgical procedure consisting in a proximal humerus osteotomy, planned with three-dimensional (3D) preoperative virtual surgery, and performed with patient-specific surgical guides, to correct humerus deformity before the implantation of the prosthetic humeral stem. A 3D evaluation of the deformity, based on the comparison to the healthy contralateral side or to anatomical standard values, is firstly performed. The metaphyseal osteotomy is then planned and virtually performed. To faithfully reproduce the planned correction, 3D printed surgical guides are prepared. Before the surgery, it is advisable to perform a simulation of the planned osteotomies to verify their real feasibility and to find any critical issues. Preliminary outcomes of this surgical technique are encouraging, but formal studies are warranted to validate its clinical utility and longevity of results.

Glenoid bone loss in anterior shoulder dislocation: a multicentric study to assess the most reliable imaging method

Marcello Zappia et al. Radiol Med. .

Abstract

Purpose: The aim of this multicentric study was to assess which imaging method has the best inter-reader agreement for glenoid bone loss quantification in anterior shoulder instability. A further aim was to calculate the inter-method agreement comparing bilateral CT with unilateral CT and MR arthrography (MRA) with CT measurements. Finally, calculations were carried out to find the least time-consuming method.

Method: A retrospective evaluation was performed by 9 readers (or pairs of readers) on a consecutive series of 110 patients with MRA and bilateral shoulder CT. Each reader was asked to calculate the glenoid bone loss of all patients using the following methods: best fit circle area on both MRA and CT images, maximum transverse glenoid width on MRA and CT, CT PICO technique, ratio of the maximum glenoid width to height on MRA and CT, and length of flattening of the anterior glenoid curvature on MRA and CT. Using Pearson's correlation coefficient (PCC), the following agreement values were calculated: the inter-reader for each method, the inter-method for MRA with CT quantifications and the inter-method for CT best-fit circle area and CT PICO. Statistical analysis was carried out to compare the time employed by the readers for each method.

Results: Inter-reader agreement PCC mean values were the following: 0.70 for MRA and 0.77 for CT using best fit circle diameter, 0.68 for MRA and 0.72 for CT using best fit circle area, 0.75 for CT PICO, 0.64 for MRA and 0.62 for CT anterior straight line and 0.49 for MRA and 0.43 for CT using length-to-width ratio. CT-MRA inter-modality PCC mean values were 0.9 for best fit circle diameter, 0.9 for best fit circle area, 0.62 for anterior straight line and 0.94 for length-to-width methods. PCC mean value comparing unilateral CT with PICO CT methods was 0.8. MRA best fit circle area method was significantly faster than the same method performed on CT (p = 0.031), while no significant difference was seen between CT and MRA for remaining measurements.

Conclusions: CT PICO is the most reliable imaging method, but both CT and MRA can be reliably used to assess glenoid bone loss. Best fit circle area CT and MRA methods are valuable alternative measurement techniques.

Computer-Aided Planning and 3D-Printed Surgical Guide in Patients with Extreme Cubitus Varus Deformity: A Report of 2 Cases

Alessandro Marinelli et al. JBJS Case Connect. .

Abstract

Case: We describe 2 patients with extreme triplanar cubitus varus deformity, treated with step-cut corrective virtually planned osteotomies and performed with custom-made surgical guides. The surgery was simulated on the patients' bone 3D-printed model to verify the effectiveness of the surgical plans. At a medium 21-month follow-up after surgery, in both patients, clinical and radiological results were fully satisfactory, and no complications have been reported.

Conclusion: The precision of computer-aided surgical planning and custom-made surgical guides allow to perform reproducible and relatively safe surgeries even in extreme deformities where the surgical complexity could discourage attempts at surgical correction.
