No dynamic technique, such as tendon transfer, has been described for scapular winging due to levator scapulae or rhomboid major and minor palsies resulting from an isolated dorsal scapular nerve injury. Thus, we evaluated how the contralateral trapezius compound osteomuscular flap transfer would work in stabilizing lateral scapular winging, and the case is reported here. A literature review was also conducted, and articles relevant to the case are presented.


A 37-year-old male patient who had sustained an isolated dorsal scapular nerve injury underwent reconstructive surgery using the contralateral trapezius compound osteomuscular flap transfer technique to treat scapular winging and the consequent pain, and to restore function from the shoulder impairment. As a result, the involved shoulder showed an improved Constant-Murley score, from 19.5% to 81.88%.


Contralateral trapezius osteomuscular flap transfer succeeded in stabilizing scapular winging in this case, improving shoulder function and affording pain relief.

Core tip: This report describes a case of scapular winging as a result of dorsal scapular nerve injury. Only few cases of winged scapula due to rhomboid paralysis are reported in the literature. Although scapular winging can seriously impair shoulder function, no dynamic techniques have been described to treat this condition. This case reveals that contralateral trapezius compound osteomuscular flap transfer can successfully stabilize lateral scapular winging due to a dorsal scapular nerve injury, while improving shoulder function and affording pain relief.


Winging of the scapula was first described over 200 years ago[1]. It remains a cause of serious impairment of upper limb function, decreasing shoulder range of motion and strength; ultimately, it affects activities such as lifting, pushing and pulling heavy objects[2], not to mention the pain associated with doing so[3,4]. In addition to these functional restrictions, it affects the shape of the back and can become an aesthetic and psychological issue[5].

To understand this pathology, the anatomy of the shoulder must be fully known. The minor rhomboid muscle originates from the cervical spinous processes 6-7 and the major rhomboid muscle from the thoracal spinous processes 1-4. The major and minor rhomboid muscles are both innervated by the dorsal scapular nerve which originates from C5 or C5 and C6[6], inserts at the scapula medially, presses the scapula on the thorax and pulls it to the spine. This anatomy preconditions for retroversion and internal rotation in antagonization of the serratus anterior muscle which is innervated by the long thoracic nerve which originates from C5, C6 and C7[7], and inserts at the scapula medially. This anatomy preconditions for anteversion and external rotation. With rhomboid muscle insufficiency, elevation of the arm is still possible but for full movement both preconditions have to be met.

The other involved muscles (function) in scapular girdle motion are: Pectoralis major muscle (anteversion, internal rotation); pectoralis minor muscle (adduction, internal rotation); coracobrachialis muscle (anteversion); deltoid muscle (abduction up to 90°, strongest anteversion with its clavicular part, internal rotation with its clavicular part, retroversion and external rotation with its spinal part); subscapular muscle (strongest internal rotation); supraspinatus muscle (external rotation and additionally abduction); infraspinatus muscle (strongest external rotation); teres major muscle (strongest retroversion, internal rotation); teres minor muscle (external rotation); latissimus dorsi muscle (adduction, retroversion, internal rotation); and, trapezoid muscle (elevation/abduction of more than 90° with its descending part). The trapezoid muscle is innervated by the spinal accessory nerve, a cranial nerve which originates from the first five to six spine segments before entering the cranium through the foramen magnum (Ramus externus or Radices spinales) and is then accompanied by its cranial part that originates from the oblongata medulla (Ramus internus or Radices craniales). Both parts run together with the vagal nerve, through the jugular foramen, before innervating the sternocleidomastoid muscle and the trapezoid muscle. Contributions to trapezius innervation by the cervical plexus have also been described but findings thus far suggest it has limited significance[8].

Many etiologies can cause scapular winging. Most cases, however, are attributed to neurological lesions. These include long thoracic, spinal accessory and dorsal scapular nerve injuries, which are linked to this problem due to paralysis of the serratus anterior, trapezius and/or rhomboid muscles, respectively. Normally, the synchronized actions of these muscles push the medial border of the scapula against the thoracic wall; dysfunction of any of them will consequently lift the medial border of the scapula away from the back. In any case, dorsal scapular nerve lesions are quite rare and the literature contains few case reports of winged scapula due to rhomboid paralysis in particular[9-11].

The direction of displacement of the inferior angle of the scapula determines whether winging will be medial or lateral. The former is due to a lack of function of the serratus anterior muscle, and the latter to a lack of function of the trapezius and/or rhomboid muscles. Winging can be also classified as primary, secondary, or voluntary. Causes of primary winging are neurological injuries, usually involving the long thoracic nerve, the accessory nerve or the dorsal scapular nerve. These occur in association with tumor on the ribs or scapula or malunited fractures of the scapula, as well as following the rupture or absence of periscapular muscles. Secondary winging is due to glenohumeral and subacromial disorders. Voluntary winging of the scapula is very rare and psychological factors play an important role[12].

Scapular winging presents a diagnostic challenge, as evidenced by the many patients that are initially misdiagnosed[13,14]. Electromyography of the serratus anterior, trapezius and rhomboid muscles is useful to inform the diagnosis and reveal which muscles are involved as well as the degree of denervation[15,16]. Electromyographic testing typically shows resting denervation potentials, decreased motor unit recruitment, and polyphasic motor unit potentials during volitional activity[17,18] if any recovery is taking place. Imaging studies are rarely diagnostic but should be performed to ascertain any structural abnormalities and aid in ruling out other diagnoses[10,15,19,20].

Transfers of several muscles have been described to treat scapular winging. In this sense, transfer of the rhomboid major and minor has been suggested to treat scapular winging due to spinal accessory nerve injury and trapezius paralysis. Transfer of the pectoralis major is widely used when scapular winging is present following a long thoracic nerve injury and serratus anterior paralysis. To the best of our knowledge, there are no reports of any muscle transfer for primary scapular winging due to an isolated dorsal scapular nerve injury.

With written informed consent, we report herein the unusual case of an adult patient who developed scapular winging on the right side due to a dorsal scapular nerve injury. We chose to treat the case with contralateral trapezius transfer, and obtained approval from the local Ethics Committee (No. JGA-TCEA-2017). The surgical technique provided successful restoration of scapulothoracic joint function and pain relief, and may be a useful means by which to treat scapular winging due to an isolated dorsal scapular nerve injury.


A 37-year-old male patient was referred to our clinic with a history of right shoulder indirect injury sustained 2 years prior (Figure 1). He worked carrying heavy marble stones. The injury had occurred when he was trying to prevent one from falling. He reported having made a sudden arm movement, followed by tremendous effort to hold the stone. Following the incident, the patient experienced right scapular winging, shoulder function impairment, and pain.

Clinical examination revealed scapular winging at rest and during both passive and active shoulder flexion (Figure 2), together with decreased active shoulder movement on the right side, having 60º flexion and 45º abduction (Figure 3). In terms of shoulder rotations, the patient was able to put his hands behind his head with elbows forward but was unable to reach his back. The patient underwent evaluation of overall function of the shoulder using the Constant-Murley score (CMS; a 100-point scale composed of several parameters that define the level of pain, function, range of motion and strength[21]). The patient’s preoperative CMS was 19.5.

Imaging studies (plain X-rays and magnetic resonance imaging) did not reveal any structural injury. Electrophysiological studies showed an isolated dorsal scapular nerve lesion and proper function of other nerves, such as the long thoracic and spinal nerves.


Dorsal scapular nerve injury.


The case was considered to be an irreparable nerve lesion given the time elapsed between nerve injury and the patient’s referral to our clinic. Nerve surgery was obviated and contralateral trapezius compound osteomuscular flap transfer was proposed to correct the scapular winging.

Surgery was performed under general anesthesia. The patient was placed in the prone position. Superficial anatomical landmarks were drawn, including scapular silhouette on both the recipient and donor sites, lateral edge of the trapezius muscle, and spinal processes from T4 to T12. Centered on a line bisecting the angle formed between midline and the lateral edge of trapezius, an “s” shaped incision was made with the caudal flap designed to expose the lowest thoracic spinal processes. A second incision was made along the medial border of the scapula at the site of injury, at the level of the scapular spine (Figure 4). At the donor site, the trapezius flap was raised and freed from its bed, from lateral to medial, and detached from the spinal processes except from the last two (T11 and T12), which were osteotomized to include two hemispinal processes in the compound flap. Bone bleeding in the flap indicated bone viability (Figure 5). The trapezius flap was detached from its insertion at the spinal processes, from T4 to T10. Continuity of the posterior elements of the spine was not interrupted and posterior interspinous ligament was spared. The compound osteomuscular trapezius flap was raised and passed through a subcutaneous tunnel towards the second incision (Figure 6). Prior to attaching the flap to the recipient site, the shoulder of the injured site was pushed backward to bring the medial border of the scapula closer to the midline. In this position, we marked the sites where the two hemispinal processes of the compound flap were to be placed on the scapular spine with the flap under maximal tension. At these sites, we created two beds in the spine of the scapula so that bone-to-bone fusion could take place between them, providing a footprint for bone-to-tendon fusion. The flap was then attached using anchors in the beds and transosseous sutures through the scapular spine (Figure 7). Nonabsorbable sutures were used. Layered closure was performed and drainage was placed in the donor site. A diagram of the surgery is provided in Figure 8.

The scapulothoracic joint was controlled postoperatively with a brace (Actimove® Clavicula; BSN Medical Inc., Rutherford College, North Carolina, United States), with both shoulders positioned “at attention” to avoid flap elongation for 6 wk. Five days later, the patient was discharged from in-patient care. Skin sutures were removed after 2 wk. Subsequently, the patient first underwent daily check-up by the therapist for a period of 2 mo, then twice weekly for another 2 mo.


CMS was measured monthly using an automated dynamometer (microFET®2; Hoggan Scientific LLC, Salt Lake City, Utah, United States). The patient then learned to dissociate donor from recipient movement by performing recipient movement without consciously thinking about donor movement (Video 1).

The patient improved his CMS from day 1 preoperative (19.5%) to 74.38% at 6 mo postoperative and 81.88% at 2 year postoperative. No additional improvement or impairment has been reported up to the last follow-up revision (30 mo postoperatively).

The patient was asked to record his preoperative and postoperative pain using a 10-cm visual analogue scale (commonly known as VAS). The preoperative level of pain of the injured shoulder was 5 on a 0-10 VAS. Following surgery, this score fell to 3 at 6-mo follow-up, and it was 0 at 2-year follow-up. Soreness was reported at the donor site for 6-mo postoperative.

Shoulder motion was measured preoperatively and in the follow-ups. Preoperative shoulder flexion and abduction were 60º and 45º, respectively; external rotation allowed the patient to reach the occipital area with elbows forward but internal rotation was severely impaired, since the patient was unable to reach his back. Postoperatively, all active ranges of motion were measured, and at 6 mo the patient achieved maximum postoperative mobility of the shoulder. This was maintained through to the last follow-up, with the patient having 155º flexion, 95º abduction, full elevation and ability to reach T12 on his back (Figure 9).

With respect to strength, the patient was able to lift up to 9.1 kg with no pain and shoulder flexed at 90º with the arm positioned in the axis of the scapula at the most recent measurement. No preoperative strength measurements were performed, since the patient was not able to achieve 90º of active flexion.

No impairment of the contralateral shoulder or scapular girdle was detected postoperatively. Scapulothoracic rhythm was not altered in the donor site, while it was improved in the recipient site.


We searched PubMed from January 1990 up to October 2018 using the search terms “dorsal scapular nerve”, “dorsoscapular nerve”, “nervus dorsalis scapulae”. Sixty-nine articles were retrieved, of which thirteen were deemed relevant and were used in this report. In addition, other topically relevant articles are discussed in order to support the treatment approach used on our patient; the treatment decision was based on the fact that, to the best of our knowledge, no dynamic technique (i.e., tendon transfer) had yet been described for scapular winging due to rhomboid major and minor palsy resulting from an isolated dorsal scapular nerve injury.

From an etiological point of view, dorsal scapular nerve injury usually occurs in the context of compressive neuropathy. The compression of the nerve has been described in situations related to sports medicine. Ravindran et al[22] presented the cases of 2 brothers who practiced volleyball at a high level, with both having developed a winged scapula as a consequence of neuropathies of the suprascapular nerve in association with neuropathy of the dorsal scapular nerve. The association of dorsal scapular nerve injury with suprascapular nerve injury has also been described by Lee et al[23]. Also in sports medicine, Jerosch et al[24] described the case of a judoka who, after suffering a dislocation of the glenohumeral joint, had a winged scapula due to injury to the long thoracic nerve and the dorsal scapular nerve.

There have also been reports of cases unrelated to sports medicine. Debeer et al[25] reported a case of compression exerted by a poorly adjusted orthosis in a patient with scoliosis. In our case, the patient suffered a dorsal scapular nerve injury in the workplace, after making an effort to lift a heavy weight. On this same topic are the case reports from Argyriou et al[26] (describing a patient with a winged scapula and work history of carrying about 8 kg of weight repetitively) and of Akgun et al[9] (describing a patient who developed an acute winged scapula after lifting heavy objects above the head). For these two patients, the cause was a compressive neuropathy of the dorsal scapular nerve.

Iatrogenic lesions of the scapular dorsal nerve also occupy an important niche in this research field. A case reported by Lee et al[27] developed as a consequence of a trigger point puncture in the rhomboid major muscle. Saporito[28] concluded that there is potential risk of damaging the dorsal scapular nerve and long thoracic nerve in the anesthetic blocks of the brachial plexus in the interscalene region. This researcher then recommended ultrasonographic localization of both nerves to avoid injuring them; this idea was based on the possible ultrasound localization in most cases as published by Hanson et al[29].

Regarding clinical manifestations, according to Muir et al[30] neuropathy of the dorsal scapular nerve can cause winged scapula to varying degrees, depending on the weakness of the major and minor rhomboid muscles. Sultan et al[31] defined, in addition to the winged scapula, other symptoms related to entrapment of the dorsal scapular nerve, such as interscapular pain. These authors attributed such symptoms to sensitization of nociceptors of the nerve sheath; although, interscapular pain may also be a consequence of the tension affecting the cutaneous medial branches of the dorsal primary rami of thoracic spinal nerves, that develops when the winged scapula occurs. We believe that the latter reasoning fits the cause of pain in our patient best, given that in our case the pain presented by the patient before the operation had a value of 5 in the VAS and that after the surgery the pain decreased in intensity without the need of perform any type of intervention on the nerve, only treating the winged scapula.

Another symptom reported by Sultan et al[31] is the loss of range of motion of the shoulder. In our case, the patient lost mobility in every arc of movement of the shoulder, which was recovered after the surgery. These features suggested to us that the loss of mobility was due to an alteration of the dynamics of the scapulothoracic joint and the unfavorable position by which the winged scapula affects all muscle groups of the scapular girdle. Although, in our patient, we did not observe the profile of symptomatology described by Sultan et al[31], such as cervicogenic dorsalgia, notalgia paresthetica and posterolateral arm pain, possibly related to dorsal scapular nerve neuropathy. Chen et al[32] have also reported discomfort and soreness of the neck, shoulder and back region too as part of the symptomology.

Argyriou et al[26] considered conservative treatment of dorsal scapular nerve neuropathy suitable for mild or moderate cases, as did Benedetti et al[33] who obtained satisfactory results through a multidisciplinary rehabilitation approach. However, for those cases in which conservative treatment is not effective, Argyriou et al[26] recommended surgical treatment. In this sense, Chen et al[32] considered that the symptoms derived from the compression of the scapular dorsal nerve can be improved if the middle scalene muscle and its tendinous tissue are sectioned in relation to the compressed nerve.

Nevertheless, nerve acute injuries are difficult to treat, given that such lesions are often diagnosed late. Motor endplate atrophy leads to suboptimal results when reconstruction is performed more than 3-6 mo after the nerve damage occurs. However, even immediate restoration of original function does not always result in satisfactory outcomes[34]. In these cases, tendinous transfers are widely used for the treatment of peripheral nerve injuries that are in the sequelae phase and otherwise not repairable. These dynamic procedures are currently the standard of care for restoration of shoulder function after chronic scapular winging from nerve palsy in younger, active people[35].

To the best of our knowledge, no dynamic technique, such as tendon transfer, has been described for scapular winging due to rhomboid major and minor palsy resulting from an isolated dorsal scapular nerve injury. Medial static stabilization of the scapulothoracic joint has been performed using strips of fascia lata. This technique was described by Ketenjian in 1978[36] and posteriorly modified by Atasoy and Majd[37], who obtained good results. Scapulothoracic fusion has also been suggested, although disparate results have been reported after fusion with complications such as pneumothorax, pleural effusion, atelectasis, fracture of the scapula, and pseudarthrosis[38].

Terzis et al[39] found that contralateral low trapezius transfer was a useful technique to treat scapular winging in patients with brachial plexus birth palsy (known as BPBP). Scapular winging in children with sequelae of BPBP is due not only to weakness of periscapular musculature but also to glenohumeral dysplasia, which results from an imbalance in the internal and external rotators of the shoulder. This dysplasia also leads to abnormal scapulothoracic movement during shoulder motion, due to both the anatomical and structural alterations of the glenohumeral joint. Moreover, most patients who suffer from BPBP sustain postganglionic root lesions where dorsal scapular, long thoracic and spinal nerves are usually spared. In these cases, scapular winging also develops, revealing that this condition is caused mainly by shoulder rotator imbalance instead of weakness of the periscapular muscles.

As described by Elhassan et al[40], contralateral trapezius transfer to the infraspinatus insertion appears feasible and has been used to restore external rotation of the shoulder by transferring to the infraspinatus insertion[41]. Given that suture is performed to join two tendons, weakness at the junction should not be a main concern in these cases, as it is when tendons are transferred to bone. The best healing interface is obtained when repair is performed between homogeneous tissues (i.e., bone-to-bone and tendon-to-tendon) and shows better healing quality with respect to mechanical and histological assessments, as compared to the healing between heterogeneous tissues (i.e., bone-to-tendon)[42]. Consequently, and given that at the recipient site muscle and bone are the only tissues available, we decided to take bone from the donor site to perform bone-to-bone fusion. Bone tissue was obtained without interrupting the continuity of the posterior elements of the spine, taking only the ipsilateral hemispinal processes and sparing the posterior interspinous ligament, not only in adjacent spinal processes (T10 and L1) but also in the affected ones (T11 and T12).

For our patient, scapulothoracic rhythm was preserved in the donor site and it was improved in the recipient site. Measurements were performed with visual inspection systems. Digital inclinometers have been recommended for quantifying shoulder and scapular kinematics[43], and it is possible that these devices would have reported subtle changes in the donor site.

We have found that contralateral trapezius compound osteomuscular flap transfer was able to successfully stabilize lateral scapular winging due to an isolated dorsal scapular nerve injury in the case reported, while improving shoulder function and affording pain relief. Further studies are needed with a larger sample size to determine whether the contralateral trapezius compound osteomuscular flap transfer technique is the best choice for patients with scapular winging due to an isolated dorsal scapular nerve injury.


Whole shoulder girdle exploration is needed when the shoulder function is impaired, since dorsal scapular nerve injury may go unnoticed without a high degree of suspicion. The contralateral trapezius compound osteomuscular flap is a technique that we consider to be not especially complex if performed by surgeons with experience in shoulder and periscapular surgery. Given the good result obtained with this dynamic technique for scapular stabilization when the scapular winging was due to dorsal scapular nerve injury, we have abandoned the static techniques that were carried out previously and that yielded worse results with higher associated morbidity.

In our patient, no complications were observed at the donor site, except for soreness reported at the 6-mo postoperative follow up. The conclusion we have come to from our experience and literature review is that contralateral trapezius transfer is a safe technique, even when the two lowest hemispinal processes are included in the flap.

Case characteristics

A 37-year-old male presented at 2 years after a right shoulder indirect injury, with right scapular winging, shoulder function impairment, and pain.

Clinical diagnosis

Physical examination of the patient suggested a lateral scapular winging. Definitive diagnosis was obtained after neurophysiological studies revealed an isolated dorsal scapular nerve injury.

Differential diagnosis

Lateral scapular winging is due to lack of function of the trapezius and/or rhomboid muscles, so these two entities should be considered. Given that in obese patients it is difficult to differentiate medial from lateral scapular winging, medial scapular winging due to lack of function of serratus anterior muscle should also be taken into account.

Laboratory diagnosis

Electrophysiological studies showed an isolated dorsal scapular nerve lesion and proper function of other nerves, such as the long thoracic and spinal nerves.

Imaging diagnosis

Imaging studies (plain X-rays and magnetic resonance imaging) did not reveal any structural injury.

Pathological diagnosis

Not applicable in this case.


Scapular stabilization was performed by attaching, to the spine of the scapula, a compound osteomuscular flap obtained from the contralateral trapezius and T11 and T12 hemispinal processes.

Term explanation

Scapular winging: Scapular malposition with its inferior angle prominent, which leads to impairment of shoulder function and pain.

Experiences and lessons

Contralateral trapezius compound osteomuscular flap is a technique that we consider not especially complex if performed by surgeons with experience in shoulder and periscapular surgery. Given the good result obtained with this dynamic technique for scapular stabilization when the scapular winging was due to dorsal scapular nerve injury, we have abandoned the static techniques that were carried out previously and that yielded worse results with higher associated morbidity.
