RESUMO
BACKGROUND: Various conservative treatments and surgical techniques have been reported in the literature as efficient and feasible measures to treat the cubital tunnel syndrome. However, there has been no consensus on the best management of the syndrome, and uniform standardised guidelines have not yet been accepted or introduced. With our study, we present our experience on the clinical efficacies and outcomes of the surgical techniques of neurolysis alone and neurolysis associated with ulnar nerve anterior transposition at the elbow joint in patients with neuropathic symptoms due to cubital tunnel syndrome. MATERIALS AND METHODS: A total of 107 patients with cubital tunnel syndrome were retrospectively enrolled, surgically treated and followed up in our study. The cohort was divided into two groups: 41 patients treated only with neurolysis of the ulnar nerve (Group 1), and 66 patients treated with neurolysis and anterior transposition (Group 2). Of the participants, 35 were women and 72 were men. The average age was 54 years. Significant comorbidities were preoperatively diagnosed in 26 patients. Conservative measures had been considered, followed by surgical management if appropriate. A pre-op electromyography was performed for all patients. All surgical procedures were performed by the same surgical team. A post-operative follow-up was carried out, and the findings were recorded. The "McGowan" and "Wilson and Krout" classifications and the DASH score were used. A satisfaction questionnaire was administered to all patients post-operatively at 2 weeks). RESULTS: Ulnar nerve neurolysis and anterior transposition surgery were all successfully performed. Overall complications were post-operative haematoma (8%) and wound problems (5%). In 6% there was recurrence of symptoms. In 11% there was no improvement of symptoms. Pre-op McGowan classifications for groups 1 and 2 were 0% and 0% (grade 0), 21% and 24% (grade 1), 46% and 44% (grade 2), and 33% and 34% (grade 3), respectively. The post-op McGowan classifications were 34% and 37% (grade 0), 39% and 40% (grade 1), 23% and 20% (grade 2), and 4% and 3% (grade 3), respectively. The post-op Wilson and Krout classifications were 45% and 46% (excellent), 26% and 28% (good), 19% and 15% (fair), and 10% and 11% (poor), respectively. The DASH score means for groups 1 and 2 were 14.8 and 15.2, respectively. A negative Froment's sign was present in 73.2% and 71.2%, respectively. In Group 1, the post-op satisfaction questionnaire scores were 0 for one patient, 1 for four patients, 2 for seven patients, 3 for ten patients, 4 for twelve patients and 5 for seven patients. In Group 2, the post-op satisfaction questionnaire scores were 0 for three patients, 1 for nine patients, 2 for twelve patients, 3 for fifteen patients, 4 for eighteen patients and 5 for nine patients. CONCLUSIONS: In our experience, the surgical technique to treat the cubital tunnel syndrome most efficiently and feasibly has not yet been established in terms of indications and outcomes. This is supported by the data present in the international literature. Good and similar results were obtained with neurolysis alone and neurolysis associated with anterior transposition of the ulnar nerve (in line with the international data). In conclusion, more high-quality studies of greater statistical power are needed to provide a consensus on the surgical indications and techniques to treat the cubital tunnel syndrome and to establish internationally standardised guidelines.

PURPOSE: Some authors consider preservation of the subscapularis tendon as one of the most important elements for a successful long-term outcome in patients operated on with open capsulorrhaphy for recurrent anterior shoulder dislocation. The purpose of this study was to evaluate whether vertical tenotomy of the subscapularis tendon might affect internal rotation strength recovery in patients operated on with open capsulorrhaphy for recurrent anterior shoulder dislocation. METHODS: Ninety-six patients were retrospectively followed up at a mean of 72.5 months. They underwent clinical evaluation, Rowe and Walch-Duplay scoring scales, the Visual Analog Scale (VAS), and dynamometric measurements (side-to-side) of internal and external rotation, forward elevation, and abduction. All patients were athletes: 25% were practising risk-free sports, 44% contact sports, 14.5% sports with cocking of the arm, and 14.5% high-risk sports activities. RESULTS: Five (5.2%) recurrences were registered, and all patients returned to pre-operative sports activity. The Rowe score was 98.12, the Walch-Duplay score 92.25, and the VAS score 0.1. Dynamometric assessment showed no significant differences (side-to-side) in internal rotation (p = 0.34), external rotation (p = 0.9), flexion (p = 0.7), and abduction (p = 0.7). Dominant arms showed better results than non-dominant arms (p < 0.01). CONCLUSION: Complete tenotomy of the subscapularis tendon does not seem to negatively affect internal rotation strength recovery or external rotation movement in athletes.

BACKGROUND: Segond's fracture is a well-recognised radiological sign of an anterior cruciate ligament (ACL) tear. While previous studies evaluated the role of the anterolateral ligament (ALL) and complex injuries on rotational stability of the knee, there are no studies on the biomechanical effect of Segond's fracture in an ACL deficient knee. The aim of this study was to evaluate the effect of a Segond's fracture on knee rotation stability as evaluated by a navigation system in an ACL deficient knee. MATERIALS AND METHODS: Three different conditions were tested on seven knee specimens: intact knee, ACL deficient knee and ACL deficient knee with Segond's fracture. Static and dynamic measurements of anterior tibial translation (ATT) and axial tibial rotation (ATR) were recorded by the navigation system (2.2 OrthoPilot ACL navigation system B. Braun Aesculap, Tuttlingen, Germany). RESULTS: Static measurements at 30° showed that the mean ATT at 30° of knee flexion was 5.1 ± 2.7 mm in the ACL intact condition, 14.3 ± 3.1 mm after ACL cut (P = 0.005), and 15.2 ± 3.6 mm after Segond's fracture (P = 0.08). The mean ATR at 30° of knee flexion was 20.7° ± 4.8° in the ACL intact condition, 26.9° ± 4.1° in the ACL deficient knee (P > 0.05) and 30.9° ± 3.8° after Segond's fracture (P = 0.005). Dynamic measurements during the pivot-shift showed that the mean ATT was 7.2 ± 2.7 mm in the intact knee, 9.1 ± 3.3 mm in the ACL deficient knee(P = 0.04) and 9.7 ± 4.3 mm in the ACL deficient knee with Segond's fracture (P = 0.07). The mean ATR was 9.6° ± 1.8° in the intact knee, 12.3° ± 2.3° in the ACL deficient knee (P > 0.05) and 19.1° ± 3.1° in the ACL deficient knee with Segond's lesion (P = 0.016). CONCLUSION: An isolated lesion of the ACL only affects ATT during static and dynamic measurements, while the addition of Segond's fracture has a significant effect on ATR in both static and dynamic execution of the pivot-shift test, as evaluated with the aid of navigation.

PURPOSE: The purpose of this study was to correlate the bone block graft position, its dimension, its reabsorption and its integration with clinical outcome in patients operated on for recurrent anterior shoulder instability. METHODS: Twenty-four patients affected by recurrent anterior shoulder dislocation and operated on using the Latarjet procedure were enrolled in this study. At 6 and 24 months, patients were evaluated with the following scales: ROWE, WOSI, Oxford instability score, UCLA, DASH and Constant score. Patients underwent two postoperative CT scans: immediately after surgery (T0) and at 24 months post-op (T1). RESULTS: At 24 months, none of the 24 patients reported further episodes of dislocation. Clinically at the final follow-up, we found excellent results in all the evaluation scales. Mean reduction in bone graft from T0 to T1 was 42% of the overall volume; similarly reduction in the overall surface was 29.3%; decrease in length, width and depth was, respectively, 3.4, 2.2 and 1.0 mm; all these parameters decreased significantly (p < 0.05). No correlations were found between radiological parameters and clinical and functional outcomes. CONCLUSIONS: The results confirm that a lack of integration or a significant reabsorption of the graft is present in the Latarjet procedure, but they do not significantly affect the clinical and functional results.

Our hypothesis is that there are no difference in the injury incidence on artificial turf and natural grass. During the 2011/2012 season, we recorded injuries which occurred to two Italian stadiums equipped with third-generation artificial turf during 36 games (391 players). Data were compared with the injuries which occurred in the same season in two stadiums equipped with natural grass (372 players). We recorded 43 injuries during the playing time (16.7 per 1000 h). About 23 (18.1 per 1000 h) injuries occurred on artificial turf, while 20 (15.2 per 1000 h) on the natural grass with no statistical differences P > 0.05. We recorded 10 (7.87 per 1000 h) contact and 13 (10.23 per 1000 h) non-contact injuries on artificial turf, while 5 (3.8 per 1000 h) contact and 15 (11.4 per 1000 h) non-contact injuries on natural grass P > 0.05. The overall relative risk was 1.15; 95% CI: 0.64-2.07). Our study demonstrates a substantial equivalence in injury risk on natural grass and artificial turf in elite professional soccer athletes during official matches.

BACKGROUND: Rotator cuff tears are closely related with muscle atrophy and fatty infiltration and both affect healing after surgical treatment. The aim of this study was to compare surgical versus conservative management of medium-to-large reparable rotator cuff tears. METHODS: Forty-one patients with clinical and radiological (MRI) diagnosis of medium-to-large rotator cuff tears were retrospectively identified and divided into two groups: Group A, arthroscopic repair; Group B, conservative treatment. At follow-up (T1) all patients underwent a new clinical (VAS, SST, Constant and Relative Constant Scale) and radiological evaluation (MRI). RESULTS: When comparing the two groups at T1 (mean follow-up: Group A, 50 months; Group B, 61 months), we registered better results in Group A in the SST (p < 0.05), the VAS score (p < 0.01), the Constant and the Relative Constant Scale (p < 0.05). Radiological evaluation did not show a significant increase of fatty infiltration (p = 0.16) in Group A (no progression in 15 out of 17 patients -82.3%-, and an increase in 2 out of 17 patients -11.7%-), while in Group B a significant increase was detected (p < 0.01) in all patients; in regard to muscle atrophy, no cases of progression were detected in Group A (4 out of 17 patients -23.5%- showed an increased post-operative supraspinatus trophysm), while a significant worsening (p < 0.05) was found in Group B. In Group B a significant worsening of tendon retraction (p < 0.01) and of tear size (p = 0.01) was also detected. CONCLUSIONS: Surgical treatment of complete rotator cuff tears seems to decrease the irreversible changes that involve muscle belly.
