Latissimus dorsi tendon transfer for massive irreparable cuff tears: an anatomic study

The purpose of this study was to describe landmarks for latissimus dorsi tendon transfer in massive irreparable tears of the rotator cuff. Nine pairs of embalmed cadaveric shoulders were dissected. Crucial structures were identified, and their relationship with various bony and soft-tissue reference points was documented. Identification of the dense fibrous band, at the confluence of the teres major and latissimus dorsi musculotendinous unit, facilitates localization of the radial nerve, which crosses deep to this landmark. The axillary nerve can be seen to exit the quadrangular space 27 mm medial to the latissimus dorsi insertion into the proximal humerus, whereas the thoracodorsal neurovascular pedicle inserts into the latissimus dorsi 110 mm from the humeral tendon's humeral attachment. Harvest of the latissimus dorsi tendon can be safely accomplished by identifying the dense fibrous band and releasing the tendon within 2 cm of its humeral attachment.     

Latissimus dorsi transfer for irreparable rotator cuff tears: a longitudinal study

Latissimus dorsi transfer is indicated for isolated posterior superior defects of the rotator cuff. Additional lesions limit the success of the outcome, but they are relatively frequent in revision surgery. We analyzed their influence on the postoperative function in 52 patients with an irreparable tear of the rotator cuff (35 primary operations, 17 revision surgeries). We observed a continuous improvement in the Constant score from 36 to 69 points, also in ROM, strength, relief of pain and of different subjective parameters for the entire group in consecutive examinations at 11.1, 35.7 and 50.2 months. We found increased osteoarthritis (from 1.0 to 1.5 mm), as well as a decrease in the acromiohumeral distance (from 5.6 to 4.7 mm). In contrast, we detected a slight decrease in the values in the revision group and in the presence of an additional subscapularis lesion.     

Latissimus dorsi transfer for the treatment of massive tears of the rotator cuff

The objective of this paper was to determine the outcome of the transfer of the latissimus dorsi tendon in patients with massive irreparable rotator cuff tears. Eighteen patients of mean age 54 years (range 37-72 years) with massive irreparable rotator cuff tears were studied. The mean follow-up was 28 months (range 12-58 months). The postoperative Constant score was higher by an average of 21.15 points compared to the preoperative score (P=0.002); 88.8% of patients reported significant pain relief and improved mobility, particularly on external rotation. Postoperative resting antero-posterior radiography in neutral rotation revealed a mean 3.2-mm depression of the humeral head, due to the tenodesis effect of tendon transfer, thus, increasing the deltoid lever arm. These clinical results suggest that latissimus dorsi transfer is a useful surgical technique for treating massive irreparable postero-superior tears of the rotator cuff in young and/or active patients, providing significant pain relief and improved shoulder strength.     

Latissimus dorsi transfer for treatment of irreparable rotator cuff tears

Massive rotator cuff tendon ruptures are not uncommon in older patients. We propose the transfer of the latissimus dorsi muscle for treatment of irreparable ruptures associated with functional impairment and chronic pain. Five women and 11 men were so treated and reviewed with an average follow-up of 26 months. The mean age was 60 years. Four patients also had subscapularis deficiency. Results were assessed with the Constant score and the Oxford shoulder score. Humeral head position was analysed. Statistical analysis was performed by the Wilcoxon non-parametrical test. The Constant score increased by 24.2% (p = 0.001) with all parameters showing improvement. Nine patients showed improved humeral head positioning in internal rotation. Three of four patients with a deficient subscapularis had unfavourable results. Latissimus dorsi transfer for the treatment of irreparable massive rotator cuff tears leads to a substantial clinical improvement. An intact subscapularis tendon is mandatory.     

Latissimus dorsi tendon transfer for irreparable posterosuperior rotator cuff tears. Factors affecting outcome

BACKGROUND: The purpose of this study was to evaluate the clinical results of latissimus dorsi tendon transfer in patients with an irreparable posterosuperior rotator cuff tear to help determine which patient and anatomic factors affect clinical outcome. METHODS: Fourteen patients with a latissimus dorsi tendon transfer were clinically evaluated with use of the PENN (University of Pennsylvania) shoulder score as well as with quantitative measurement of isometric muscle strength and the range of motion of both shoulders at a minimum of twenty-four months postoperatively. The anatomic results were evaluated with postoperative magnetic resonance imaging and electromyography. RESULTS: Nine patients were satisfied with the outcome, had significant clinical improvement, and reported that they would have the operation again under similar circumstances. The other five patients were dissatisfied with the result and had significantly worse PENN scores, active elevation, and objective measures of strength. Eight of the nine patients with a good clinical result were male, and four of the five with a poor result were female. Patients with a good clinical result had had significantly better preoperative function in active forward flexion and active external rotation compared with the patients with a poor result. The magnetic resonance imaging demonstrated healing of the tendon to the greater tuberosity in twelve patients and equivocal healing in two. There was no significant atrophy of any of the transferred muscles. Electromyography demonstrated clear activity in the transferred latissimus muscle during humeral adduction in all fourteen patients, some electrical activity with active forward elevation in only one patient, and some electrical activity with active external rotation in six of the nine patients with a good clinical result. None of the patients with a poor clinical result demonstrated electrical activity of the transferred muscle with active forward flexion or external rotation. CONCLUSIONS: Synchronous in-phase contraction of the transferred latissimus dorsi is a variable finding following the surgical treatment of irreparable posterosuperior rotator cuff tears, but when it is present it is associated with a better clinical result. Preoperative shoulder function and general strength influence the clinical result. Female patients with poor shoulder function and generalized muscle weakness prior to surgery have a greater likelihood of having a poor clinical result.     

Latissimus dorsi transfer for primary treatment of irreparable rotator cuff tears

Transfer of the musculotendinous unit of the latissimus dorsi was performed in seven patients (5 men and 2 women, with a mean age of 57 years) with irreparable rotator cuff tear who had had no previous surgery for cuff repair. Preoperatively, the mean active shoulder motion was 86° in flexion, 74° in abduction and 22° in external rotation. One patient had a positive lift-off test. The average preoperative Constant and Murley score was 44%. Diagnosis of irreparability of the cuff leasion was made preoperatively only in one case. In the remaining patients, the preoperative data only led to suspect that the tear was irreparable. At surgery, all patients had an irreparable tear of the superoinferior portion of the cuff and one patient also had a tear of the subscapularis tendon. In all cases the latissimus dorsi tendon was inserted to the greater tuberosity and, in four cases, to the subscapularis tendon; in three patients it was sutured to the bicipital tendon. Postoperatively all patients had relief of shoulder pain. The mean improvement in active flexion, abduction and external rotation was, respectively, 39°, 29° and 10°: At the latest follow-up, the average Constant and Murley score was 64%. The results of surgery were rated as excellent in three cases, good in two, fair in one and poor in one. All patients but one returned to preoperative work. Transfer of the latissimus dorsi muscle is an effective procedure for patients in middle or early elderly age who have an irreparable tear of the supraspinatus and infraspinatus tendons.

Latissimus dorsi transfer for the treatment of irreparable rotator cuff tears

BACKGROUND: Treatment of irreparable rotator cuff tears remains controversial. Latissimus dorsi transfer to the greater tuberosity has been proposed for the treatment of irreparable tears associated with severe functional impairment and chronic, disabling pain. METHODS: Sixty-seven patients with sixty-nine irreparable, full-thickness tears of at least two complete tendons were managed with latissimus dorsi transfer and were reviewed clinically and radiographically after an average of fifty-three months. The study group included fifty-two men and fifteen women, with an average age of sixty-one years. Thirteen patients also had deficient subscapularis function preoperatively. Outcome measures included the Constant and Murley score and the Subjective Shoulder Value. Osteoarthritis and acromiohumeral distance were measured on standardized radiographs. RESULTS: The mean Subjective Shoulder Value increased from 28% preoperatively to 66% at the time of follow-up (p < 0.0001). The mean age and gender-matched Constant and Murley score improved from 55% to 73% (p < 0.0001). The pain score improved from 6 to 12 points (of a possible 15 points) (p < 0.0001). Flexion increased from 104 degrees to 123 degrees , abduction increased from 101 degrees to 119 degrees , and external rotation increased from 22 degrees to 29 degrees (p < 0.05). Abduction strength increased from 0.9 to 1.8 kg (p < 0.0001). There was a slight but significant increase in osteoarthritic changes (from stage 0.8 to stage 1.3; p = 0.0002). In shoulders with a negative preoperative lift-off test, significant improvements were observed in terms of both function and pain, and strength doubled from 1.0 to 2.0 kg (p = 0.0001), but osteoarthritic changes progressed from stage 0.7 to stage 1.1 (p = 0.0006). In shoulders with poor subscapularis function, no improvement in these parameters was observed. CONCLUSIONS: Latissimus dorsi transfer durably and substantially improves chronically painful, dysfunctional shoulders with irreparable rotator cuff tears, especially if the subscapularis is intact. If subscapularis function is deficient, the procedure is of questionable benefit and probably should not be used.     

Latissimus dorsi tendon transfer: A comparative analysis of primary and salvage reconstruction of massive, irreparable rotator cuff tears

On the basis of a modified Constant scoring system, we compared outcomes for 16 patients who underwent latissimus dorsi transfer as a salvage reconstruction for a failed prior rotator cuff repair with outcomes for 6 patients who underwent a primary reconstruction for an irreparable cuff defect. There was a statistically significant difference in Constant score between groups, which measured 55% for the salvage group compared with 70% for the primary group (P <.05). Poor tendon quality, stage 4 muscle fatty degeneration, and detachment of the deltoid insertion each had a statistically significant effect on the Constant score (P <.05). Late rupture of the tendon transfer occurred in 44% of patients in the salvage group compared with 17% in the primary group at a mean of 19 months postoperatively. Rupture had a statistically significant effect on the Constant score, which declined by a mean of 14% (P <.05). We conclude that salvage reconstruction of failed prior rotator cuff repairs yields more limited gains in satisfaction and function than primary latissimus dorsi transfer.     

Latissimus dorsi tendon transfers for rotator cuff deficiency

Purpose:

Latissimus dorsi tendon transfers are increasingly being used around the shoulder. We aim to assess any improvement in pain and function following a latissimus dorsi tendon transfer for massive, irreparable postero-superior cuff deficiency.

Materials and Methods:

At our institution, between 1996 and 2009, 38 latissimus dorsi tendon transfer procedures were performed. Sixteen of these were for massive irreparable rotator cuff deficiency associated with pain and impaired function. All patients were evaluated by means of interview or postal questionnaire and case note review. Pain and function were assessed using the Stanmore percentage of normal shoulder assessment (SPONSA) score, visual analogue scale and Oxford Shoulder Score. Forward elevation was also assessed and a significant improvement was thought to correlate with the success of the procedure at stabilizing the humeral head upon elevation.

Results:

Mean follow-up time was 70 months. There was a significant reduction in pain on the visual analogue scale from 6.4 to 3.4 (P < 0.05), an improved SPONSA score from 32.5 to 57.5 (P < 0.05), and an improved Oxford Shoulder Score from 40.75 to 29.6 (P < 0.05). Forward elevation improved from 40° preoperatively to 75° postoperatively (P < 0.05).

Conclusion:

Our results add to the body of evidence that latissimus dorsi tendon transfers for irreparable postero-superior cuff deficiency in selected patients reduce pain and improve shoulder function in the medium term.

Level of Evidence:

Level 4.     

Latissimus dorsi transfer for the treatment of massive tears of the rotator cuff. A preliminary report

Symptomatic irrepairable rotator cuff tears usually entail complete loss of the substance of the supraspinatus and infraspinatus tendons. Loss of external rotation control and cranial migration of the humeral head on attempted flexion or abduction of the shoulder are the functional hallmarks. Transfer of the latissimus dorsi tendon from the humeral shaft to the superolateral humeral head provides a large, vascularized tendon that can be used to close a massive cuff defect and that exerts an external rotation and head-depressing moment that allow more effective action of the deltoid muscle. This procedure was carried out in 14 patients without any significant complications. Pain relief and functional results in those four cases with a minimum follow-up period of one year (average, 14 months) compared favorably with alternative treatment methods and warrant further anatomic, electromyographic, and clinical investigation.     

Latissimus dorsi transfer for the treatment of irreparable tears of the rotator cuff.

Sixteen irreparable, massive rotator cuff tears were treated with latissimus dorsi transfer and reviewed after an average of 33 months. There were no neurovascular complications or infections. Pain relief was satisfactory in 94% of the shoulders at rest and in 81% on exertion. Flexion was 83 degrees preoperatively and 135 degrees postoperatively. The functional value of the shoulder averaged 73% of an age- and gender-adjusted normal score. For the 12 shoulders with a functional subscapularis, it averaged 82%; for those four without a functioning subscapularis, 48%. If the subscapularis was torn and could not be adequately repaired, latissimus dorsi transfer was of no value. In cases with good subscapularis function but irreparable defects in the external rotator tendons, restoration of approximately 80% of normal shoulder function was obtained, indicating that latissimus dorsi transfer is a safe and valuable alternative for the treatment of this specific type of irreparable rotator cuff tear.     

Combined pectoralis major and latissimus dorsi tendon transfer for massive rotator cuff deficiency

This report is a retrospective review of 11 consecutive patients treated with a combined transfer of the latissimus dorsi and pectoralis major tendons for massive rotator cuff deficiency. Each patient's chief complaint was diminished shoulder function and motion with little or no accompanying pain. The primary operative objective was to increase active shoulder motion. All 11 patients were followed up for at least 2 years (range, 24 to 42 months). The mean active elevation improved from 42 degrees preoperatively to 86 degrees postoperatively. The mean active external rotation improved from 0 degrees to 13 degrees. On the basis of the Medical Research Council scale, the mean abduction strength improved from 2.3 to 3.1 and the mean external rotation strength improved from 2.1 to 2.7. Overall, 4 patients made no improvement, 2 improved slightly, and 5 improved significantly. We conclude that a combined transfer of the latissimus dorsi and pectoralis major is a reasonable and safe procedure that may restore active elevation and external rotation in some patients' shoulders with a massive rotator cuff deficiency that have not responded favorably to traditional nonoperative and operative techniques. However, it is difficult to conclude, based on our experience, for which patients this surgery can be predictably successful.     

Teres minor integrity predicts outcome of latissimus dorsi tendon transfer for irreparable rotator cuff tears

In patients with irreparable rotator cuff tears, latissimus dorsi tendon transfer (LDTT) can be effective in improving pain and function. However, the results are variable, and the factors that predict good outcomes are poorly understood. The purpose of this study was to investigate whether the integrity of the teres minor musculotendinous unit is predictive of outcome following LDTT. Twenty-two consecutive patients who underwent LDTT for massive, irreparable posterosuperior rotator cuff tears were retrospectively reviewed. Sixteen men and 6 women with a mean age of 58 years (range, 40-68) were analyzed at an average follow-up of 34 months (range, 24-57). Standardized MRI images of all patients were reviewed by 3 independent reviewers. Fatty infiltration of the teres minor was Goutallier stage 0 in 5 patients; stage 1 in 6; stage 2 in 4; stage 3 in 6; and stage 4 in 1. Eleven patients (50%) had partial tears and 2 (9%) had complete tears of the teres minor tendon. Following LDTT, the mean absolute constant score improved from 48 to 62 points (P = .003), age-adjusted constant score improved from 56% to 72% (P = .002), and the subjective shoulder value improved from 24% to 68% (P < .001). Fatty infiltration of the teres minor less than or equal to stage 2 was associated with a better postoperative constant score (67 vs 53, P = .015); age-adjusted constant score (78% vs 59%, P = .012); active external rotation (36 degrees vs 16 degrees , P = .016); and active elevation (143 degrees vs 115 degrees , P = .012) relative to patients with fatty infiltration greater than stage 2. The presence or absence of a tear of the tendon had no significant effect on outcome. In conclusion, when performing LDTT for massive irreparable posterosuperior rotator cuff tears, fatty infiltration of the teres minor should be considered prior to surgery, as it is predictive of outcome.     

Outcome of latissimus dorsi transfer for irreparable rotator cuff tears

The aim of this retrospective study was to assess the mid- and long-term functional and radiological results following latissimus dorsi transfer for symptomatic irreparable tears of the supra- and infraspinatus tendons (postero-superior cuff tears). Twenty-six shoulders with an irreparable posterosuperior rotator cuff tear were assessed preoperatively and after latissimus dorsi transfer, using the Constant score and standard radiographs to determine the degree of osteoarthritis and to measure the acromio-humeral distance. After a minimal follow-up of one year (range: 13 to 124 months) we observed a significant increase in Constant score from 39 to 60 points at the time of the last follow-up (p < 0.00001). Eighty-five percent of the patients were satisfied or very satisfied with the result and would undergo the same surgery again. An increase in the grade of gleno-humeral osteoarthritis was noted in 38.5% of the operated shoulders, and this was associated with a lower Constant score. We noted a decrease in acromio-humeral distance, indicating further proximalisation of the humeral head, but this was not significant (p = 0.049).
