Objective To investigate the effectiveness of “hybrid” suture with en masse combined with double-layer repair under arthroscopy in repair of delaminated rotator cuff tear by comparison with en masse suture. MethodsFifty-six patients with delaminated rotator cuff tears met selection criteria between June 2020 and January 2022 were included in the study. Patients were divided into two groups (n=28) using a random number method. The patients in trial group underwent arthroscopic “hybrid” suture with the combination en masse and double-layer suture. The patients in control group underwent en masse suture under arthroscopy. There was no significant difference between the two groups (P>0.05) in terms of gender, age, rotator cuff tear side, tear size, cause of injury, disease duration, and preoperative American Association of Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) shoulder scoring, visual analogue scale (VAS) score, and shoulder range of motion (forward flexion and lateral external rotation). The operation time, the difference of ASES score, UCLA score, VAS score, and shoulder range of motion (forward flexion and lateral external rotation) between pre- and post-operation were recorded and compared between the two groups (P>0.05). The rotator cuff healing was examined by MRI and evaluated based on the classification criteria of rotator cuff healing proposed by Sugaya et al. Results Three cases (1 case in the trial group and 2 cases in the control group) were excluded from the study due to loss of follow-up. Twenty-seven cases in the trial group and 26 cases in the control group were included in the final study analysis. All operations of the two groups were completed successfully. There was no significant difference in the operation time between groups (P>0.05). The follow-up time was 10-12 months (mean, 10.9 months) in the trial group and 10-13 months (mean, 11.4 months) in the control group. All incisions healed by first intention. No surgery-related complications occurred. The UCLA score, ASES score, VAS score, and shoulder range of motion (forward flexion and lateral external rotation) of both groups at 9 months after operation were significantly superior to those before operation (P<0.05). The difference of UCLA score, ASES score, and VAS score between before and after operation in the trial group were significantly better than those in the control group (P<0.05). There was no significant differences between the two groups in the difference of shoulder range of motion (forward flexion and lateral lateral rotation) (P>0.05). At 9 months after operation, according to the classification criteria of rotator cuff healing proposed by Sugaya et al, MRI showed that the rotator cuff healing of the trial group was significantly better than that of the control group (P<0.05). Conclusion Compared with en masse suture, arthroscopic “hybrid” suture for the repair of delaminated rotator cuff tear has advantages in relieving pain and improving shoulder joint function, and the rotator cuff healing is better.
Objective
To explore the effectiveness of the arthroscopic separate double-layer suture bridge technique in treatment of the delaminated rotator cuff tear.
Methods
Between May 2013 and May 2015, 54 patients with the delaminated rotator cuff tears were recruited in the study. They were randomly allocated into 2 groups to receive repair either using arthroscopic separate double-layer suture bridge technique (trial group, n=28) or using arthroscopic whole-layer suture bridge technique (control group, n=26). There was no significant difference in gender, age, injured side, tear type, and preoperative visual analogue scale (VAS) score, Constants score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score, and the range of motion of shoulder joint between 2 groups (P>0.05). Postoperative functional scores, range of motion, and recurrence rate of tear in 2 groups were observed and compared.
Results
The operation time was significant longer in trial group than in control group (t=8.383, P=0.000). All incisions healed at stage Ⅰ without postoperative complication. All the patients were followed up 12 months. At 12 months postoperatively, the UCLA score, ASES score, VAS score, Constant score, and the range of motion were significantly improved when compared with the preoperative values in 2 groups (P<0.05). However there was no significant difference in above indexes between 2 groups (P>0.05). Four cases (14.3%) of rotator cuff tear recurred in trial group while 5 cases (19.2%) in control group, showing no significant difference (χ2=0.237, P=0.626).
Conclusion
Compared with the arthroscopic whole-layer suture bridge technique, arthroscopic separate double-layer suture bridge technique presents no significant difference in the shoulder function score, the range of motion, and recurrence of rotator cuff tear, while having a longer operation time.
ObjectiveTo investigate the mechanisms,diagnosis,and surgical procedures of simultaneous lesions of the rotator cuff and the brachial plexus.
MethodsBetween July 2006 and June 2012,7 patients with rotator cuff tear associated with brachial plexus injury were treated.There were 3 males and 4 females with a mean age of 47.3 years (range,37-72 years).The reasons of injury were traumatic shoulder dislocation in 6 cases and falling injury from height in 1 case,with a mean disease duration of 17 days (range,5-31 days).The average American Shoulder and Elbow Surgeons (ASES) score was 55.86±9.42,and visual analogue scale (VAS) score was 7.14±1.35.There were 3 cases of large rotator cuff tears (>3 cm) and 4 cases of massive rotator cuff tears (>5 cm) according to Gerber standard;1 case had upper trunk injury of the brachial plexus and 6 cases had bundle branch injury of the brachial plexus according to GU Yudong's classification.The functional score of brachial plexus score was 7.43±1.27 according to the functional assessment standard by Hand Surgery Branch of Chinese Medical Association.All patients accepted arthroscopic rotator cuff repairing,and 1 case received surgical neurolysis of brachial plexus.
ResultsAll incisions healed by first intention without complication.All the 7 patients were followed up 18 to 25 months (mean,20.4 months).The function,muscle strength,and sensation of the shoulder were improved obviously.The shoulder ASES score was 84.71±8.06 and was significantly better than preoperative score (t=-8.194,P=0.000).The VAS score was 2.71±1.50 and was significantly better than preoperative score (t=7.750,P=0.000).The functional score of brachial plexus was 14.00±1.16 and was significantly better than preoperative score (t=-11.500,P=0.000).
ConclusionIt is difficult to simultaneously diagnose lesions of the rotator cuff and the brachial plexus;orthopedists should pay attention to possible patients to avoid missed diagnosis and diagnostic errors.Nerve nutrition,physical therapy,and arthroscopic rotator cuff repair can achieve good effectiveness.
Objective To investigate the synergistic interaction between the deltoid muscle and the rotator cuff muscle group in patients with rotator cuff tears (RCT), as well as the impact of the critical shoulder angle (CSA) on deltoid muscle strength. Methods A retrospective analysis was conducted on clinical data from 42 RCT patients who met the selection criteria and were treated between March 2022 and March 2023. There were 13 males and 29 females, with an age range of 42-77 years (mean, 60.5 years). Preoperative visual analogue scale (VAS) score was 6.0±1.6. CSA measurements were obtained from standard anteroposterior X-ray films before operation, and patients were divided into two groups based on CSA measurements: CSA>35° group (group A) and CSA≤35° group (group B). Handheld dynamometry was used to measure the muscle strength of various muscle group in the shoulder (including the supraspinatus, infraspinatus, subscapularis, and anterior, middle, and posterior bundles of the deltoid). The muscle strength of the unaffected side was compared to the affected side, and muscle imbalance indices were calculated. Muscle imbalance indices between male and female patients, dominant and non-dominant sides, and groups A and B were compared. Pearson correlation analysis was used to examine the relationship between muscle imbalance indices and CSA as well as VAS scores. Results Muscle strength in all muscle groups on the affected side was significantly lower than on the unaffected side (P<0.05). The muscle imbalance indices for the supraspinatus, subscapularis, infraspinatus, and anterior, middle, and posterior bundles of the deltoid were 14.8%±24.4%, 5.9%±9.7%, 7.2% (0, 9.1%), 17.2% (5.9%, 26.9%), 8.3%±21.3%, and 10.2% (2.8%, 15.4%), respectively. The muscle imbalance indices of the anterior bundle of the deltoid, supraspinatus, and infraspinatus were significantly lower in male patients compared to female patients (P<0.05); however, there was no significant difference in muscle imbalance indices among other muscle groups between male and female patients or between the dominant and non-dominant sides (P>0.05). There was a positive correlation between the muscle imbalance indices of infraspinatus and VAS score (P<0.05), and a positive correlation between CSA and the muscle imbalance indices of middle bundle of deltoid (P<0.05). There was no correlation between the muscle imbalance indices of other muscle groups and VAS score or CSA (P>0.05). Preoperative CSA ranged from 17.6° to 39.4°, with a mean of 31.1°. There were 9 cases in group A and 33 cases in group B. The muscle imbalance indices of the anterior bundle of the deltoid was significantly lower in group A compared to group B (P<0.05), while there was no significant difference in muscle imbalance indices among other muscle groups between group A and group B (P>0.05). ConclusionPatients with RCT have a phenomenon of deltoid muscle strength reduction, which is more pronounced in the population with a larger CSA.
ObjectiveTo summarize the research progress of the greater tubercle fixation and the rotator cuff repair in humeral head replacement.MethodsThe literature about proximal humerus fracture and humeral head replacement in recent years was extensively consulted and analyzed.ResultsThe greater tubercle fixation and the attached rotator cuff repair have great influence on the function of shoulder joint after humeral head replacement. It is difficult to make an objective comparison because of lack of direct comparison between various methods, unified standards of grading, and limited number of cases.ConclusionIt is an important factor of reduction and fixation of greater tubercle to obtain better effectiveness in humeral head replacement. However, one-stage repair of rotator cuff is more important than greater tubercle fixation for functional recovery of shoulder joint.
Arthroscopic rotator cuff repair is widely used clinically, but the phenomenon of re-tear after repair is still common. Due to the special structure of the tendon-bone junction, the promotion of tissue regeneration from the perspective of biological enhancement has attracted attention. Platelet-rich plasma (PRP) is a supraphysiological concentration of autologous platelets, which can promote the healing of rotator cuff injury after repair. However, due to the lack of clinical use standards, not all PRPs are the same, there are clear differences between liquid PRP and solid platelet-rich fibrin, and many studies have not differentiated their properties. This article reviews the research progress of different types of PRP in the repair of rotator cuff injury, aiming to provide some reference for clinical treatment selection.
Rotator cuff injuries are often associated with long head of biceps tendon (LHBT) lesions, which are more common in middle-aged and older adults. With the continuous updating of diagnosis and treatment techniques and treatment concepts in recent years, many patients can receive effective diagnosis and treatment. This article starts from the anatomy, etiology, diagnosis and treatment progress of rotator cuff and LHBT, and details the related research progress of rotator cuff injury combined with LHBT at home and abroad. This paper focuses on the significance of paying attention to LHBT lesions while dealing with rotator cuff injuries, aiming to improve clinicians’ understanding of rotator cuff injuries combined with LHBT lesions, explore accurate and effective diagnosis and treatment systems, so as to choose the best treatment method.
Objective To compare the effectiveness of the long head of the biceps tendon (LHBT) with or without proximal amputation after arthroscopic rotator cuff repair in the treatment of repairable rotator cuff tear with LHBT injury. Methods The clinical data of 68 patients with LHBT injury combined with supraspinatus tendon tear who met the selection criteria between January 2016 and June 2020 were retrospectively analyzed. According to whether the proximal end of LHBT was cut off or not after arthroscopic rotator cuff repair, they were divided into LHBT fixation without cutting group (group A, 32 cases) and LHBT fixation with cutting group (group B, 36 cases). There was no significant difference in gender, age, operating side, preoperative supraspinatus tear width, Constant-Murley shoulder function scale, University of California Los Angeles (UCLA) score, and visual analogue scale (VAS) score between the two groups (P>0.05). The operation time, elbow flexion muscle strength, and postoperative complications were compared between the two groups. The Constant-Murley shoulder function scale, UCLA score, and VAS score were used to evaluate the recovery of shoulder function before operation and at 3, 6, 12 months after operation. The acromion-humeral distance (AHD) was measured by Y-view X-ray film of the shoulder joint immediately after operation and at last follow-up. AHD and acromion-greater tubercle distance (AGT) were measured by musculoskeletal ultrasound at 0°, 30°, 60°, and 90° of abduction. Results There was no significant difference in operation time between the two groups (t=–0.740, P=0.463). Patients in both groups were followed up (13.0±0.7) months in group A and (13.1±0.8) months in group B, with no significant difference (t=0.127, P=0.899). At last follow-up, the elbow flexor muscle strength of the two groups reached grade Ⅴ. Complications (including shoulder pain, deltoid atrophy, and rotator cuff re-tear) occurred in 6 patients (18.75%) in group A and 9 patients (25.00%) in group B, without neurovascular injury, surgical site infection, joint stiffness, LHBT spasmodic pain, and Popeye deformity. There was no significant difference in the incidence of complications between the two groups (χ2=0.385, P=0.535). The Constant-Murley shoulder function scale, UCLA score, and VAS score significantly improved in both groups at 3, 6, and 12 months after operation (P>0.05). The above scores in group B were significantly better than those in group A at 3 and 6 months after operation (P<0.05), and there was no significant difference between the two groups at 12 months after operation (P>0.05). Y-view X-ray film measurement of the shoulder joint showed that the AHD of the two groups at last follow-up was less than that at immediate after operation, but the difference was not significant (Z=?1.247, P=0.212); the AHD of group A was significantly greater than that of group B at last follow-up (t=?2.291, P=0.025). During musculoskeletal ultrasound detection of abduction and shoulder lift, there was no significant difference in the reduction degree of AHD and AGT in group A with abduction of 0°-30° compared with group B (P>0.05). The reduction degree of AHD and AGT in group A with abduction of 30°-60°, and the reduction degree of AGT in group A with abduction of 60°-90° were significantly smaller than those in group B (P<0.05). Conclusion In arthroscopic rotator cuff repair, whether the proximal structure of LHBT is cut off or not after LHBT fixation can effectively improve the symptoms of patients and promote the recovery of shoulder joint function. Compared with preserving the proximal structure of LHBT, cutting the proximal structure of LHBT after LHBT fixation has more obvious pain relief within 6 months, and the latter had better stability above the shoulder joint.
Objective
To investigate effectiveness of rotator cuff repair with manipulation release and arthroscopic debridement for rotator cuff tear with shoulder stiffness.
Methods
A retrospectively study was performed on the data of 15 patients with rotator cuff tear combined with shoulder stiffness (stiff group) and 24 patients without stiffness (non-stiff group) between January 2014 and December 2015. The patients in the stiff group underwent arthroscopic rotator cuff repair with manipulation release and arthroscopic debridement while the patients in the non-stiff group only received arthroscopic rotator cuff repair. The patients in the stiff group were older than the patients in the non-stiff group, showing significant difference (P<0.05). There was no significant difference in gender, type of rotator cuff tear, side of rotator cuff tear, and combined with diabetes between 2 groups (P>0.05). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were used to evaluate the effectiveness after operation.
Results
All incisions healed by first intention without any complication after operation. The patients were followed up 13-31 months in the stiff group (mean, 19.2 months) and 13-23 months in the non-stiff group (mean, 20.3 months). There was no significant difference in follow- up time between 2 groups (t=–0.573, P=0.570). The VAS score in the stiff group was higher than that in the non-stiff group before operation (t=–2.166, P=0.037); there was no significant difference between 2 groups at 3, 6, 12 months and last follow-up (P>0.05). The forward flexion and external rotation were significantly lower in the stiff group than those in the non-stiff group before operation and at 3 months after operation (P<0.05); there was no significant difference between 2 groups at 6, 12 months and last follow-up (P>0.05). At last follow-up, the internal rotation was beyond L3 level in 2 groups. The preoperative UCLA score was significant lower in the stiff group than that in the non-stiff group (P=0.037); but there was no significant difference in UCLA score at last follow-up between 2 groups (P=0.786). There was no significant difference in pre- and post-operative ASES scores between 2 groups (P>0.05).
Conclusion
Satisfactory effectiveness can be achieved in the patients with rotator cuff tear combined with shoulder stiffness after rotator cuff repair with manipulation release and arthroscopic debridement, although the patients with shoulder stiffness had slower postoperative recovery of ROM until 6 months after operation.
