Shoulder Intra-Articular Temperature Is Higher In Patients With Small Rotator Cuff Tears Compared With Patients Who Have Larger Tears.

Purpose: The purpose of this study was to determine whether the intra-articular temperature of the shoulder correlates with the size of the tendon tear in patients with rotator cuff tears (RCTs). Methods: The shoulder intra-articular temperature of 75 consecutive (32 female, 43 male; mean age 61.12; standard deviation = 7.10) patients who underwent arthroscopic rotator cuff repair was measured with a digital thermometer, at first in 2 points (biceps anchor and glenoid labrum) during dry arthroscopy, followed by a third measurement during wet arthroscopy. A fourth measurement, represented by the patient's axillary body temperature, was taken upon admission. The RCTs were classified during surgery according to the Southern California Orthopedic Institute classification system as small, large, and massive. Data were submitted for statistical analysis. Results: The intra-articular temperature differs in patients with different-sized RCTs regardless of the location of the thermometer. A significantly higher temperature was found in patients with small RCTs (36.2°C ± 0.57°C) (P < .01). When the in-flow of the arthroscopic fluid was opened, the temperature dropped to an average of 24.5°C. Conclusions: The shoulder intra-articular temperature was significantly associated with RCT size. A significantly higher temperature was found in small RCTs. No correlation was found between age and sex, age and RCT size, sex and RCT size, or sex and temperature. Clinical Relevance: An early diagnosis and treatment of RCTs may avoid further degeneration and damage of the tendon caused by the increased temperature.

Three Years of COVID-19 on Orthopaedic Trauma; Are We Going Back to Normality?

Background and Objective: On March 2020, our country became a protected area due to the COVID-19 pandemic. The consequences of COVID-19 on trauma surgery were great. We aimed to evaluate the activity of the Trauma Centre of a highly populated suburban area over 30 days starting from the first day of restrictions, to compare it with the same period of 2019 and 2022 and to evaluate whether a progressive return to normality has taken place. Materials and Methods: All patients older than 18 years managed in our Trauma Unit between 8 March 2020 and 8 April 2020 (the first COVID-19 period) were compared to the same period of 2019 (a COVID-19 free period) and 2022 (the second COVID-19 period). Clinical records were examined. Five categories of diagnoses and six mechanisms of injury were distinguished. Results: There were 1351 patients [M:719-F:632; mean age (SD):49.9 (18.7)], 451 [M:228-F:223; mean age (SD):55.9 (18.4)] and 894 [M:423-F:471;mean age (SD):54.1 (16.7)] in the COVID-19 free and in the first and second COVID-19 periods, respectively (p < 0.05). In 2020, the most significant decrease was registered for sprains/subluxations (80%); contusions decrease by 77% while fractures decrease only by 37%. The lowest reduction was found for dislocations (26%). In 2022, dislocations decreased by only 16% and both fractures and sprains decreased by about 30% with respect to the pre-pandemic period. Patients with minor trauma (contusions) were half compared to 2019. Accidental falls remain the most frequent mechanism of injury. The incidence of proximal femur, proximal humerus and distal radius fractures remained almost unchanged during both pre-pandemic and pandemic periods. Conclusions: COVID-19 has markedly altered orthopaedic trauma. Injuries related to sports and high energy trauma/traffic accidents drastically reduced in 2020; however, we are slowly going back to normality: the same injuries increased in 2022 due to the progressive easing of restrictions. Elderly fractures related to accidental falls remained unchanged.

Aetiopathogenesis of Rotator Cuff Tear in Patients Younger than 50 Years: Medical Conditions Play a Relevant Role.

Background and Objectives: Studies on rotator cuff tears (RCT) in patients younger than 50 years have focused on the post-operative outcomes. Little is known about cuff tear etiopathogenesis, although it is a common belief that most tears are due to trauma. We have retrospectively verified the prevalence of medical conditions, whose role in tendon degeneration development have been widely demonstrated, in a group of patients younger than 50 years with postero-superior RCT. Materials and Methods: 64 patients [44M-20F; mean age (SD): 46.90 (2.80)] were enrolled. Personal data, BMI, smoking habit, diseases (diabetes, arterial hypertension, hypercholesterolaemia, thyroid diseases, and chronic obstructive pulmonary disease) were registered. The possible triggering cause and the affected side and tear dimensions were recorded, and statistical analysis was then performed. Results: 75% of patients had one or more diseases and/or a smoking habit for more than 10 years. In the remaining 25%, only four patients referred had had a traumatic event, while in the other eight patients, both medical condition and trauma were registered. The presence of two or more diseases did not affect RCT size. Conclusions: In our series, three quarters of patients with RCT had a smoking habit or medical conditions predisposing them to a tendon tear; therefore, the role of trauma in RCT onset in patients younger than 50 years is markedly resized. It is plausible that in the remaining 25%, RCT may be due to trauma or to genetic or acquired degeneration. Level of Evidence: IV.

Shoulder Long Head Biceps Tendon Pathology Is Associated With Increasing Rotator Cuff Tear Size.

PURPOSE: To evaluate the association between rotator cuff tear (RCT) size and long head biceps tendon (LHBT) pathology. METHODS: We retrospectively enrolled 202 consecutive patients (114 women and 88 men with mean age at surgery of 62.14 years [SD, 7.73]) who underwent arthroscopic rotator cuff repair for different sized full-thickness RCTs. LHBT pathology was evaluated considering the presence of inflammation, section alteration, loss of integrity, dislocation, dynamic instability, and absence. The site of LHBT pathology was evaluated considering 3 portions: (1) the insertional element; (2) the free intra-articular portion; (3) the part that enters the intertubercular groove. Statistics were evluated. RESULTS: The LHBT was absent in 22 cases (10.9%): 2, 4, 15, and 1 patients with small, large, massive, and subscapularis RCTs, respectively. A significant correlation was found between the prevalence of LHBT absence and massive RCTs (P < .001). In 53 patients (26%), there was a healthy LHBT; a healthy LHBT was present in 47%, 20% and 8% of small, large and massive RCTs, respectively. A significant correlation between LHBT inflammation, section alteration, loss of integrity, and RCT severity was found (P < .001, P < .001, and ). The insertional portion was the most involved (57% of cases); RCT severity was significantly associated with the number of involved portions (P < .001). CONCLUSIONS: Shoulder LHBT pathology is associated with increasing rotator cuff tear size. CLINICAL RELEVANCE: Surgeons should be aware that biceps pathology is particularly prevalent in patients with larger RTCs.

The 2-Scope Technique for Rotator Cuff Surgery: Are 2 Scopes Better Than 1?

The arthroscopic treatment of rotator cuff tear involves 2 distinct phases: intra-articular and subacromial. We present the 2-scope technique with the aim to simultaneously perform these phases, entrusting them to 2 experienced surgeons, and to obtain possible benefits compared with the classic 1-scope technique. Better nosology of the lesion and a more accurate evaluation of suture passer action (equidistance of the sutures and avoidance of degenerated articular-side tendon areas) represent benefits of this technique. In contrast, the 2-scope technique needs an additional lateral portal and could give rise to an erroneous distribution of costs and surgeons.
