IntroductionNumerous pedicle and free flaps have been used to cover complex defects of the shoulder girdle and posterior neck triangle following tumor resection. We describe our choice of flap selection in these patients with case examples.Presentation of casesThree cases examples demonstrate our choice of flap selection. In the first case, an anterior shoulder girdle defect is covered by an anteriorly transposed latissimus dorsi muscle flap. The second case demonstrates the coverage of a posterior shoulder girdle defect by a posteriorly transposed latissimus dorsi muscle flap. Finally, the third case demonstrates the coverage of a posterior triangle neck defect using a superiorly transposed pectoralis major muscle flap. All reconstructions utilize muscle flaps (covered by split-thickness skin grafts) and not myocutaneous flaps.DiscussionWe demonstrate that these two pedicle muscle flaps are adequate for coverage of large complex defects of the shoulder girdle and posterior neck triangle. We also demonstrate the advantages of using muscle rather than myocutaneous flaps.ConclusionPedicle latissimus dorsi and pectoralis major muscle flaps are simpler and preferred over free flaps for coverage of complex defects of the shoulder girdle and posterior neck triangle. The use of muscle rather than myocutaneous flaps will reduce the size of the original defect, make flap design easier and reduce donor site morbidity. 相似文献

Flaps composed of the latissimus dorsi and the serratus anterior muscles have been used to repair extensive defects in 10 patients with no remarkable disabilities of shoulder function. The latissimus dorsi and serratus anterior muscles are consistently nourished through the subscapular-thoracodorsal vessels. Thus, the 2 flaps can be based on 1 vascular pedicle. If required, the ribs beneath the serratus anterior muscle, which are vascularized by the periosteal circulation, can be transferred with the muscle. The vascular pedicle of this flap is long and anatomically reliable. Care must be taken to avoid tension or torsion of the pedicle when positioning the flap. 相似文献

Anatomical data related to the thoracotomies performed most frequently in lung surgery are described in some detail: continuity between serratus anterior and levator scapulae as a vide muscular sheet possessing a common deep aponeurosis (thoracolumbar fascia) extending Gilis' space to the vertebral column as the levator scapulae-thoraci space; presence of a "composite aponeurosis" in the posterior angle between serratus anterior and levator scapulae, covering the 8th rib triangle or triangle of auscultation; long costal insertion area and presence of two differently orientated muscle layers for the digitations, particularly of apical bundle. Supplied by a rich vascularization of multiple sources, the serratus anterior and latissimus dorsi are two muscles with single longitudinal nerve pedicles derived from brachial plexus. It is certainly the denervation which is responsible for the distal atrophy of these muscles "sectioned on the right of the selected ribs" following conventional thoracotomy. To avoid esthetic and functional sequelae this innervation must be preserved as far as possible by: interrupting division of serratus anterior anterior to long thoracic nerve and avoiding inclusion of axillary border of latissimus dorsi during lateral thoracotomy; sectioning the latissimus dorsi as low as possible--the other muscles being simply freed and inclined--during lateral thoracotomy. 相似文献

Muscles used for transfer ought to have adequate structural properties. The purpose of this study was to provide a database of potential excursion (muscle excursion without reference to connective tissue restraints) and relative tension (muscle physiologic cross-sectional area in percentage among a group) in shoulder girdle muscles. Thirteen muscles in 13 human cadavers aged 17 to 89 years at death were studied. Potential excursion ranged from 6.7 cm (supraspinatus) to 33. 9 cm (latissimus dorsi). Relative tension ranged from 1.7% (levator scapulae) to 20.9% (deltoid). Significant discrepancies were found between the properties of some of the muscles used as transfers around the shoulder and the properties of the muscles for which they are commonly used as substitutes. Despite the limitations of cadaveric studies and the fact that many other factors are involved in muscle transfers, this database of structural properties of shoulder girdle muscles may help when planning tendon transfers around the shoulder. 相似文献

Management of soft-tissue defects of the shoulder is described. Extensive defects of soft tissues with or without overlying skin were created after resection of sarcomas in five patients. Reconstruction was performed using musculocutaneous flaps, which included three pedicle latissimus dorsi and two free tensor fascia lata flaps. Simultaneous functioning replacement of the defects of the trapezius and deltoid muscles were each achieved in two patients. Primary wound healing was achieved, and each patient recovered good contour of the shoulder. Functional results were satisfactory in all patients with an average score of 93.4% (range, 83%-100%) using the system of the Musculoskeletal Tumor Society. The four functioning muscles recovered active contraction in the transferred position. The shoulder elevation was normal in three patients, and was 90 degrees and 30 degrees in one patient each. All patients remained disease-free at the time of latest follow-up. Thus, shoulder defects of the soft tissues can be managed appropriately with the two representative musculocutaneous flaps. 相似文献

Background Tumor extirpation around the shoulder can result in large defects requiring coverage of allograft-alloprosthetic constructs
and vital neurovascular structures. This study examined a single institution’s experience with the pedicled latissimus dorsi
flap in reconstructing large shoulder defects after oncologic resection.
Methods Using a prospectively maintained database, 33 consecutive patients were reviewed who had undergone a pedicled latissimus dorsi
flap to reconstruct oncologic shoulder defects between 1994 and 2004. Wide excision or radical en-bloc resection of shoulder
tissues was performed with defects often extending intra-articularly and to the level of the mid-arm. Patient demographics,
comorbid conditions, pathology, adjuvant treatment, defect characteristics, skin paddle dimensions and operative records were
evaluated. Outcome variables included major and minor complications, patient survival, and limb viability.
Results Adjuvant therapy included chemotherapy in 18 patients, radiation therapy in 12 patients, and brachytherapy in 2 patients.
Defects averaged 280.1 cm2 (range 18–1,225 cm2). Mean skin paddle surface area was 118.9 cm2 (range 21–350 cm2). There were 28 myocutaneous flaps and 5 muscle flaps. Materials for bony reconstruction included 13 allograft and alloprosthetic
composites, 6 metallic prostheses, and 3 reconstructions using allograft alone. Two patients experienced partial skin flap
necrosis. One patient developed local recurrence. Two patients required combined flaps.
Conclusions Use of the pedicled latissimus dorsi flap in complex shoulder reconstructions provided ample well-vascularized soft tissue,
minimized risk of infection, and maximized limb salvage. In our experience, the pedicled latissimus dorsi flap is an excellent
choice for reconstruction of defects around the shoulder after tumor extirpation. 相似文献

Tissue with a blood supply derived from a single constant vascular pedicle may be raised as a flap and rotated within the reach of its blood supply to cover and reconstruct a variety of complex wounds. The latissimus dorsi muscle makes an ideal pedicled flap because of its long neurovascular pedicle, large size, ease of mobilization, and expendability. It can be rotated, with or without overlying skin, to cover soft-tissue defects involving the shoulder, arm, and elbow, or it can be transferred as an innervated muscle to improve shoulder abduction as well as elbow flexion and extension. The major clinical applications of the pedicled latissimus dorsi muscle flap for upper-extremity reconstruction include use as a bipolar transfer to improve elbow flexion after trauma or brachial plexus injury and as a nonfunctioning myocutaneous transfer for coverage of nerves, bones, and joints after soft-tissue loss due to trauma, tumors, infection, or irradiation. 相似文献

The serratus anterior muscle and rib composite flap has been well described for oral and mandibular reconstruction. The flap may also be used in combination with the latissimus dorsi flap based on the common thoracodorsal vascular pedicle, a blood supply which has hitherto been proven to be reliable. This case demonstrates a totally independent arterial supply to the serratus anterior and latissimus dorsi muscles. 相似文献

Current indications for shoulder arthrodesis include posttraumatic brachial plexus injuries, paralysis of the deltoid muscle and rotator cuff, chronic infection, failed revision arthroplasty, severe refractory instability, and bone deficiency following resection of a tumor in the proximal aspect of the humerus. The trapezius, levator scapulae, serratus anterior, and rhomboid muscles must be functional to optimize the functional result following shoulder arthrodesis. A consensus has not been reached concerning the ideal position of the shoulder arthrodesis, although excessive abduction or flexion has been associated with chronic postoperative pain. Decortication of both the acromiohumeral and the glenohumeral surfaces to increase the surface area available for arthrodesis is the most common means for obtaining successful fusion. Although there are numerous methods for stabilization of a shoulder arthrodesis, the most popular method today is probably the AO technique with either a single plate or double plates. 相似文献

Breast reconstruction utilizing the latissimus dorsi musculocutaneous flap with an underlying breast implant is a well-established technique. Postoperative shoulder limitation is usually limited if at all noticeable. The muscle itself may, however, remain active in the new anterior position. Many patients find the muscle twitches with extension of the humerus, despite the anterior translocation of the muscle. This leads to a disturbing contraction, superolaterally, of the entire reconstruction. In addition, the resting tone can lead to a sense of tightness, despite a lack of clinically obvious capsular contracture. Division of the thoracodorsal nerve during initial flap elevation can prevent this problem. When raising the routine flap however, the pedicle itself is often not visualized and there is anxiety related to dividing the nerve and accidentally injuring the vascular pedicle. In addition, many of the transferred muscles atrophy, thereby avoiding this potential problem. When the muscle remains active, delayed division of the thoracodorsal nerve via a 2.5-cm axillary incision will stop the active twitching, decrease the resting tone of the muscle, and in most patients offer significant relief from symptoms of tightness. During the past 2 1/2 years, 100 latissimus dorsi flap breast reconstructions in 80 patients were performed. Forty-one nerves in 28 patients have been divided, with successful denervation in 37 of the 41 reconstructions, for a success rate of 90%. Delayed division of the thoracodorsal nerve can offer relief to patients complaining of tightness and muscle activity post-latissimus flap breast reconstruction. 相似文献

A case of recurrent tuberculous abscess in the chest wall which was successfully treated by resection of the rib and transposition with a latissimus dorsi muscle flap is reported. A 70-year-old man was admitted to the hospital for the purpose of receiving tuberculostatic treatment after an operation for tuberculous abscess in the chest wall at another hospital. When he first visited the another hospital, he had complained of a left chest wall tumor and Mycobacterium tuberculosis was isolated from the pus. After admission to the hospital, tuberculous abscess recurrenced in the left chest wall 2 months after the operation. We performed resection of the abscess, 5th and 6th ribs, as well as transposition of the latissimus dorsi muscle flap. There have been no signs of recurrence and is followed in the clinic, as of 4 months after the operation. We think that resection of the abscess, ribs, and, transposition of the muscle flap are useful methods for tuberculous abscess in the chest wall. 相似文献

Single pedicle microvascular transfers of the serratus anterior and latissimus dorsi muscles in rats
In the rat, the serratus anterior and latissimus dorsi muscles receive axial vascular pedicles from the thoracodorsal artery. This anatomy was confirmed by dissections, and 10 microvascular transfers of the latissimus-serratus flap on a common pedicle were performed with a 90% success rate. The flaps had an average weight of 1.8 g. This flap is a reliable small animal model for microvascular muscle transplants and contains sufficient tissue to be used in multiple biochemical assays. 相似文献

The latissimus dorsi was transferred as a pedicle flap in ten patients and as a free vascular flap in ten others for extremity reconstruction. Group I comprised ten patients in whom the transfer was used solely to cover a skin or soft-tissue defect. Although there was partial necrosis of the transferred skin in one patient, the remaining nine patients obtained complete coverage without further reconstructive surgery. Group II comprised five patients in whom transfer of the latissimus dorsi was performed for active flexion or extension of the elbow or for abduction of the shoulder. Postoperatively, muscle strength obtained was classified from Grades 0 to 5 according to the muscle testing method. Three patients obtained muscle strength of Grade 3, while two obtained Grade 2. Group III comprised five patients who had brachial plexus palsy after high-dose irradiation. Coverage of the skin and soft tissue was performed after neurolysis of the brachial plexus palsy to free the tissue bed of scarred tissue. Postoperatively, sensory and motor disturbances were alleviated in four of five patients. 相似文献

The results of clinical studies on 16 reconstruction procedure after total layer chest wall resection in 14 cases of malignant tumor of the chest wall were reported. The 14 cases consisted of two cases with recurrent primary chest wall tumor, two cases of primary breast cancer, seven cases of recurrent breast cancer, and others. The reconstruction procedure after total layer chest wall resection was conducted using only various myocutaneous flaps (eight cases using latissimus dorsi of the resected side, three cases using the abdominitis of the resected side, three cases using latissimus dorsi of the non-resected side, and two cases using a pectoralis major myocutaneous flap of the non-resected side). reconstruction only using a myocutaneous flap proved to be satisfactory for preventing early stage postoperative respiratory distress and maintaining the stability of the chest wall and respiratory function during prolonged observation. Namely, use of myocutaneous flap is the best approach of reconstruction the chest wall after total layer chest wall resection. We confirmed that reconstruction with latissimus dorsi myocutaneous free flap of the non-resected side with microvascular anastomosis of thoracodorsal vessels was useful for posterior chest wall tumors invading the latissimus dorsi muscle. Also, our results demonstrated the insertion of an omental flap under the myocutaneous flap was useful for cases with secondary chest wall infection or vascular damage caused by preoperative high dose irradiation. 相似文献

Single-stage reconstruction of the chest wall combined with simultaneous augmentation mammoplasty and transfer of an island pedicle myocutaneous flap of latissimus dorsi muscle are major improvements over previous multiple-stage procedures that provide less satisfactory cosmetic results in management of patients with Poland's syndrome. Utilization of the single-stage technique in 2 patients demonstrated its efficacy as proven by excellent cosmetic results. In 1 patient with absent second, third, and fourth costal cartilages and ribs, Marlex mesh covered with a synthetic dura mater graft was employed to stabilize the chest wall. Simultaneously, an island pedicle myocutaneous flap of latissimus dorsi with its neurovascular bundle preserved was transferred to cover the prosthesis. The other patient had a coexistent pectus carinatum defect, which was repaired by resection of the costal cartilages and osteotomy of the sternum without use of Marlex. The breast implant was covered concomitantly with the myocutaneous flap of latissimus dorsi. No morbidity or mortality occurred. The cosmetic and functional results are superior to those obtained with standard techniques. 相似文献

Anatomy of the scapulothoracic articulation 总被引:3,自引:0,他引:3
Williams GR Shakil M Klimkiewicz J Iannotti JP 《Clinical orthopaedics and related research》1999,(359):237-246
Four fresh frozen human cadavers (eight extremities) consisting of the head, neck, thorax, and entire upper extremities were used for dissection of the scapulothoracic articulation. In each specimen, the spinal accessory nerve, all relevant muscle insertions, and bursae were identified and measured. The structures of the scapulothoracic articulation can be divided into superficial, intermediate, and deep layers. The superficial layer consists of the trapezius, latissimus dorsi, and an inconsistent bursa between the inferior angle of the scapula and the latissimus dorsi. The intermediate layer consists of the levator scapulae, rhomboid minor and major, spinal accessory nerve, and scapulotrapezial bursa located between the superomedial scapula and the overlying trapezius. In all specimens, the spinal accessory nerve traveled intimately along the wall of the scapulotrapezial bursa, an average of 2.7 cm lateral to the superomedial angle of the scapula. The deep layer consists of the serratus anterior, subscapularis, and two bursae: one between the serratus and the thorax, the scapulothoracic bursa; and one between the subscapularis and the serratus, the subscapularis bursa. 相似文献
