Bipolar latissimus transfer for restoration of elbow flexion

Bipolar Pedicled Latissimus Dorsi Flap for Soft-Tissue Coverage and Restoration of Elbow Function

Bipolar latissimus dorsi transfer has been considered a viable option for the restoration of elbow flexion in patients with large traumatic defects of the anterior arm compartment. Advantages of bipolar transfer of the latissimus include stabilization of the anterior shoulder joint in addition to recreating the biceps for a direct line of pull in restoring elbow flexion with minimal donor site morbidity. Previous literature in bipolar latissimus transfer has demonstrated good outcomes in elbow flexion against gravity, range of motion, and patient satisfaction. We present a step-by-step demonstration of a bipolar pedicled latissimus dorsi transfer for restoration of elbow function and soft-tissue coverage for large traumatic defects to the anterior compartment of the arm.

Functional reconstruction of elbow flexion with latissimus dorsi muscle rotational transfer: two case reports

BACKGROUND

We report two cases of biceps brachii and brachialis paralysis due to musculocutaneous nerve injury in which elbow joint flexion was reconstructed using rotational transfer of the latissimus dorsi muscle with sutures to the radial and ulnar tuberosities, thereby enabling flexion by simultaneous activation of the humeroradial and humeroulnar joints. In cases of associated brachialis paralysis, weaker flexion strength can be expected when the forearm is in a pronated position than when it is in a supinated state. To the best of our knowledge, no previous study has reported the rotational position of the forearm during elbow joint flexion reconstruction.

CASE PRESENTATION

Case 1 involved a 30-year-old Asian male who presented with a rupture of the musculocutaneous, median, radial, and ulnar nerves. Reconstruction was performed by rotational transfer of the latissimus dorsi muscle. In this case, the supination and pronation flexion forces were equal. Case 2 involved a 50-year-old Asian man who presented with partial loss of the musculocutaneous nerve, biceps brachii, and pectoralis major due to debridement. Reconstruction was performed by rotational transfer of the latissimus dorsi muscle. In this case, supination and pronation flexion strengths were demonstrated to be equal. Our reconstruction method used the rotational transfer of the latissimus dorsi muscle; the distal muscle flap was divided into radial and ulnar sides to allow elbow joint flexion by simultaneously activating the humeroradial and humeroulnar joints. These sides were then fixed to the anchors at the radial and ulnar tuberosities. Finally, they were wrapped around the myotendinous junction of the biceps brachii or brachialis and secured using sutures.

CONCLUSIONS

Although larger studies are required to verify these methods, this case study successfully demonstrates the following: (1) the flexion strength in the supinated position was equal to that in the pronated position; (2) the stability of the humeroradial and humeroulnar joints was unaffected by the forearm's rotational position; and (3) a satisfactory range of motion of the elbow joint was obtained, with no complications.

Unipolar Latissimus Dorsi Transfer for Restoration of Elbow Flexion in Residual Post-traumatic Brachial Plexus Palsy Associated with Distal Humeral Fractures

Introduction  Elbow flexion is indispensable for both functioning and nonfunctioning hands. It is well perceived that restoration of elbow function is the first reconstructive priority in cases of brachial plexus injuries. The authors assessed the impact of associated distal humeral fractures on the functional outcome after unipolar latissimus dorsi transfer (ULDT) for restoration of elbow flexion in patients with residual brachial plexus palsy (BPP). Patients and Methods  Twenty-three patients operated for restoring elbow flexion after residual post-traumatic BPP (with or without distal humeral fracture) by unipolar latissimus dorsi transfer (ULDT) were reviewed for a retrospective study. Patients were divided into two groups; associated distal humeral fracture group (HF-group; 10 patients) and non-associated distal humeral fracture group (NHF-group; 13 patients). Elbow flexion active range of motion (AROM), flexion deformity in addition to Mayo Elbow Performance Score (MEPS) were assessed. Results  In both groups there were statistically better postoperative MEPS grading ( p  = 0.007, p  = 0.001 , respectively) and scoring with a mean of 81 ± 16.1 and 90 ± 4.6, respectively ( p < 0.001). The mean postoperative elbow flexion AROM was statistically better in both groups. The mean supination AROM was better in NHF group ( p  = 0.057). Conclusion  The use of ULDT in residual post-traumatic BPP is an efficient procedure in regaining functional flexion and supination. An associated distal humeral fracture does not significantly affect the final functional outcome. Level of Evidence  Level IV.

Free Vascularized Fibular Flap with Bilateral Bipolar Latissimus Transfer for Upper Extremity Reconstruction: A Case Report

CASE

A 19-year-old woman presented with bilateral mangled upper extremities after jumping in front of a moving train. After revascularization, osteocutaneous free vascularized fibula flap was performed to reconstruct the right humerus. The left forearm required transradial amputation with acute targeted muscle reinnervation. Finally, staged bilateral bipolar latissimus dorsi functional muscle flaps were performed to restore elbow flexion.

CONCLUSION

Staged orthoplastic reconstruction of the upper extremities is an effective treatment approach for traumatic bone and soft-tissue defects. This patient's recovery demonstrates improved quality of life after severe upper extremity trauma.

Brachial Plexus Injuries - Review of the Anatomy and the Treatment Options

Brachial plexus injuries are still challenging for every surgeon taking part in treating patients with BPI. Injuries of the brachial plexus can be divided into injuries of the upper trunk, extended upper trunk, injuries of the lower trunk and swinging hand where all of the roots are involved in this type of the injury. Brachial plexus can be divided in five anatomical sections from its roots to its terminal branches: roots, trunks, division, cords and terminal branches. Brachial plexus ends up as five terminal branches, responsible for upper limb innervation, musculocutaneous, median nerve, axillary nerve, radial and ulnar nerve. According to the findings from the preoperative investigation combined with clinically found functional deficit, the type of BPI will be confirmed and that is going to determine which surgical procedure, from variety of them (neurolysis, nerve graft, neurotization, arthrodesis, tendon transfer, free muscle transfer, bionic reconstruction) is appropriate for treating the patient.

Loss of Elbow Flexion in Congenital Arthrogryposis Treated with a Bipolar Latissimus Transfer: A Case Report

CASE

A 20-year-old man with congenital arthrogryposis presented for evaluation of biceps dysfunction. Although his left elbow was supple with 0° to 110° passive range of motion (ROM), he had no active ROM and was unable to perform basic activities of daily living such as bringing his hand to his mouth to feed himself. A bipolar latissimus transfer was performed to achieve functional active ROM.

CONCLUSION

Bipolar latissimus transfer is a challenging, robust flap able to restore active elbow flexion in select groups of patients with biceps dysfunction, supple elbow, and functional latissimus dorsi.

Surgical reconstructions for adult brachial plexus injuries. Part I: Treatments for combined C5 and C6 injuries, with or without C7 injuries

Brachial plexus injuries will cause a significantly decreased quality of life. Patients with upper arm type brachial plexus injuries, which means C5 and C6 roots injury, will lose their shoulder elevation/abduction/external rotation, and elbow flexion function. Additional elbow, wrist, and hand extension function deficit will occur in patients with C7 root injury. With the advances of reconstructive procedures, the upper arm brachial plexus injuries can be successfully restored through nerve repair, nerve grafting, nerve transfer, muscle / tendon transfer and free functioning muscle transfer. In this review article, we summarized the various reconstructive procedures to restore the function of shoulder and elbow. Nowadays, the upper arm type BPI can be treat with satisfied outcomes (80-90% successful rate).

Restoration of elbow active flexion via latissimus dorsii transfer in patients with arthrogryposis

Background. Severe hypoplasia (or aplasia) of the biceps brachii is a primary cause of restriction in activities of daily living in patients with arthrogryposis. Aim. To estimate the possibility of restoring elbow active flexion via a latissimus dorsii transfer in patients with arthrogryposis. Materials and methods. From 2011 to 2018, we restored active flexion of the elbow via a latissimus dorsi transfer to the biceps brachii in 30 patients with arthrogryposis (44 upper limbs). We used different regimes including clinical examinations, EMG donor and recipient sites, and CT of the chest wall and shoulder. Results. The mean age of the patients was 4.0 ± 2.4 years, and the follow-up period was 3.2 ± 1.9 months. Follow-up results were available for 26 patients (30 upper limbs). The active postoperative elbow motion was 90.5 ± 14.9°. Elbow extension limitation occurred in 51% of cases (12.8 ± 4.3°) without any problems in activities of daily living. In total, 55.6% of patients had good results, 33.3% had satisfactory results, and 11.1% had poor results. Discussion. Our latissimus dorsi transfer results were comparable with those of other authors. Transposition of the latissimus dorsi to the biceps brachii restores sufficient flexion of the elbow without severe elbow flexion contractures. Conclusions. We suggest pedicle monopolar latissimus dorsi transfer as a reliable therapeutic option to restore active elbow flexion in patients with arthrogryposis having passive elbow flexion of 90° or higher before operation and donor muscle strain grade 4 or higher.

Is bipolar latissimus dorsi transfer a reliable option to restore elbow flexion in children with arthrogryposis? A review of 13 tendon transfers

BACKGROUND

Scant data are published about different available therapeutic options for restoration of active elbow flexion in arthrogryposis with varying degrees of improvement. In this retrospective study we evaluated medium-term effects of bipolar latissimus dorsi transfer in patients with arthrogryposis.

METHODS

Pedicled latissimus dorsi bipolar muscle transfer was used to restore elbow flexion in 11 patients (13 limbs) with arthrogryposis. Elbow and shoulder range of motions and strength of elbow flexion were measured preoperatively and at the last follow-up. The functional use of the upper limb was examined by observation of activities of daily living and presence of adaptive mechanisms. General satisfaction was assessed at the final follow-up.

RESULTS

The patients were a mean age of 5.69 ± 2.49 years. The follow-up period was 27.31 ± 17.8 months. At the last examination, according to transferred muscle function and elbow range of motion, function of 12 limbs was graded as excellent and good, and 1 was graded poor. The active postoperative elbow range of motion was 97.7° ± 34.5°. The general satisfaction of the patients with the surgical results was 92.3%. Activities of daily living were improved in 10 of 13 limbs, but adaptive mechanisms were detected in all patients except 2 at the last follow-up.

CONCLUSIONS

We suggest pedicled bipolar latissimus dorsi transfer as a reliable therapeutic option to restore active elbow flexion in arthrogryposis with acceptable results regarding regaining range of motion and patient satisfaction. Functional passive elbow range of motion and good quality of latissimus dorsi muscle preoperatively is mandatory.

Bipolar Transfer of Latissimus Dorsi Myocutaneous Flap for Restoration of Elbow Flexion in Late Traumatic Brachial Plexus Injury: Evaluation of 13 Cases

BACKGROUND

Restoration of elbow flexion following traumatic brachial plexus injury represents a great challenge to the reconstructive surgeons. Functional muscle transfers come next to the sophisticated types of nerve surgery in this area. Many transfers are well known for restoration of elbow flexion; bipolar or unipolar latissimus dorsi, triceps brachii, sternocleidomastoid, pectoralis major, and Steindler flexorplasty.

OBJECTIVE

Evaluation of the outcome of bipolar transfer of latissimus dorsi myocutaneous flap when used to restore elbow flexion in late traumatic brachial plexus injury.

PATIENTS AND METHODS

Thirteen patients were included in this case series with careful evaluation both preoperatively and postoperatively both clinically and using electromyography.

RESULTS

Almost 84.6% of patients (11 of 13) developed G3-4 on the Medical Research Council grading with relatively minimal both donor-site and recipient-site morbidity.

CONCLUSIONS

Bipolar transfer of latissimus dorsi myocutaneous flap is a reliable method for restoration of elbow flexion in patients suffering from late sequelae of traumatic brachial plexus injury.

Triceps to biceps transfer for restoration of elbow flexion following upper brachial plexus injury

INTRODUCTION

Upper brachial plexus injury in adults causes loss of elbow fl exion; when the primary nerve surgery has failed or the patient seeks treatment after 12 months of injury and pedicled muscle transfers are required. Most commonly, the latissimus dorsi or the Steindler flexorplasty is used.

MATERIAL AND METHODS

We have transferred one of the heads of triceps muscle to restore the elbow flexion in such cases. In addition to return of elbow flexion, extension of elbow following surgery is retained. Ten patients suffering from upper brachial plexus injuries underwent transfer of one head of triceps to biceps tendon between December 2011 and August 2015.

RESULTS

The recovery of elbow flexion was Grade 5 in 1, Grade 4 in 4 and Grade 3 in 2; only three of the ten patients had no functionally useful elbow flexion. Seven of the ten patients had an adequate elbow extension following the procedure.

Bipolar Latissimus Dorsi Transfer through a Single Incision: First Key-Step in Poland Syndrome Chest Deformity

Supplemental Digital Content is available in the text.

Poland syndrome is a rare congenital anomaly characterized by a unilateral congenital absence of the sternocostal head of the pectoralis major muscle. The absence of the pectoralis major does not only result in chest asymmetry but also in a missing anterior axillary fold, which is essential for natural anatomical appearance in both male and female patients. In Poland syndrome patients, we perform bipolar latissimus dorsi flap transfer, which can be associated with a sublatissimus implant in women. All procedures are performed through a single short midaxillary incision, and tendon translocation in this technique allows the creation of the anterior axillary fold and thus a natural chest appearance. Moreover, this technique can be performed by any plastic surgeon operating under a basic operating room setting.
