The rectus femoris myocutaneous flap for closure of difficult wounds of the abdomen, groin, and trochanteric areas

Use of flaps in inguinal lymphadenectomy in metastatic penile cancer

PURPOSE

Reviewing surgical procedures using fasciocutaneous and myocutaneous flaps for inguinal reconstruction after lymphadenectomy in metastatic penile cancer.

MATERIAL AND METHODS

We reviewed the current literature of the Pubmed database according to PRISMA guidelines. The search terms used were "advanced penile cancer", "groin reconstruction", and "inguinal reconstruction", both alone and in combination. The bibliographic references used in the selected articles were also analyzed to include recent articles into our research.

RESULTS

A total of 54 studies were included in this review. About one third of penile cancers are diagnosed with locally advanced disease, often presenting with large lymph node involvement. Defects in the inguinal region resulting from the treatment of metastatic penile cancer are challenging for the surgeon and cause high patient morbidity, rendering primary closure unfeasible. Several fasciocutaneous and myocutaneous flaps of the abdomen and thigh can be used for the reconstruction of the inguinal region, transferring tissue to the affected area, and enabling tensionless closure.

CONCLUSIONS

The reconstruction of defects in the inguinal region with the aid of flaps allows for faster postoperative recovery and reduces the risk of complications. Thus, the patient will be able to undergo potential necessary adjuvant treatments sooner.

Imaging finding and arthroscopic treatment of isolated contracture of the rectus femoris muscle: a case report

Background

Isolated rectus femoris (RF) contracture is encountered very rarely in orthopaedic practices. There are few reports on its imaging manifestations and no cases reported to be treated with arthroscopy.

Case presentation

A 11-year-old girl with a more than 7 years history of restricted left knee flexion was presented. The clinical assessment and magnetic resonance imaging (MRI) findings were detailed here. A strip-like induration was palpated in the left thigh, which tends to be more obvious with knee flexion. MRI demonstrated a hypointensity band connected the anterior inferior iliac spine with the patella, and marked atrophy of the left RF muscle. Fibrosis contracture band was confirmed with arthroscope, then divided by radiofrequency ablation (RFA) under arthroscopic observation. Followed by debridement of the fibrillar connective tissue and hemostasis around the broken ends. The movement of left knee joint significantly improved after the operation, and the patient recovered nearly full range of motion of this joint after 6 months.

Conclusion

The specific MRI findings could assist in confirming clinical early diagnosis of isolated RF contracture. Arthroscopic RFA treatment is an effective technique to treat this disorder with minimally incision.

Donor-site morbidity of the pedicled rectus femoris muscle flap

The rectus femoris muscle flap is well known for its reliable anatomy, the ease with which it can be harvested, and its great versatility. As a pedicled or free flap, it is used to cover soft-tissue defects and to recreate motor function. Although the muscle is very reliable, it is not well respected because of its assumed donor-site morbidity, such as weakened knee extension force and decreased range of motion of the knee. To date, these clinical assumptions have only rarely been quantified in terms of objective scores, concerning force deficit and functional or aesthetic outcome. From 1995 to 2002, the authors treated 24 patients with pedicled rectus femoris muscle flaps. Fourteen patients were followed up. Follow-up time ranged from 3 to 56 months postoperatively. The results were evaluated by a standard questionnaire in which pain in relation to walking distance, subjective feeling of weakness, sensibility disorders, everyday function, and aesthetic aspects were assessed. Range of motion in the hip and the knee was measured. For objective verification of a decrease of maximal voluntary contraction force of the remaining quadriceps muscle and for detecting differences in true muscular capacity and voluntary activation, 10 patients with unilateral rectus femoris flaps were tested using the twitch interpolation technique. The authors' patients assessed the remaining function and the aesthetic result of the thigh as at least satisfactory. Two patients complained about pain and weakness in the thigh. Eight patients reported hypesthesia in the lateral suprapatellar region. The maximal voluntary contraction and true muscular capacity values were reduced by 21.8 percent and 18 percent, respectively, when compared with the healthy leg. The range of motion in the knee and hip was not influenced by muscle harvesting. The twitch interpolation technique revealed a mild voluntary activation deficit, probably caused by inhibitory regulation in the spinal cord. In conclusion, donor-site morbidity of the rectus femoris muscle flap is evident but well compensated. There is no decrease in active range of motion in the knee and hip. Patient satisfaction with the functional and aesthetic outcome was high.

Rotational muscle flap closure for acute groin wound infections following vascular surgery

Since 1996, 41 patients have presented to our institution with deep but localized groin infection following bypass (30) or isolated femoral artery surgery (11). These patients were treated with antibiotics, debridement, and rotational muscle flap coverage either immediately or within a few days. Patients had one of three patterns: serous leak from a groin incision within a few days of operation (Acute, n = 10), early serous leak that later became grossly infected (Acute-observed, n = 8), or obvious purulent drainage following an initially normal, healed wound (Delayed, n = 23). Patients with early leak had nearly uniformly polymicrobial infections with a preponderance of gram-negative organisms, whereas most of those with late purulence had monobacterial infection with Staphylococcus aureus. At exploration, 26 of 41 suture lines were exposed. Rectus femoris flaps were used in 35 patients (85% of cases) for coverage, and graft preservation was attempted in all 8 vein grafts and 16 of 23 prosthetic grafts. Only one flap failed and there were no instances of anastomotic bleeding. There were no deaths directly attributable to reexploration and flap coverage, although 10 patients died during the index hospitalization. Durable coverage with no long-term evidence of infection was achieved in 24 patients with mean follow-up of 23 (range 10-66) months and another 12 had no evidence of local problems despite shorter follow-up; only 5 patients (12%) overall had evidence of persistent graft infection or unexplained bacteremia. In patients with attempted graft salvage, limb salvage was 97% at 6 months and 85% at 1 year. Although early mortality is high, deaths are not related to the flap procedure itself, local outcome is excellent, and graft and limb salvage are good; results are much worse if an initially draining wound is treated too late. Local rotational muscle flap closure is an excellent solution for acute infections involving the groin following vascular procedures.

Management of Complex Groin Wounds: Preferred Use of the Rectus Femoris Muscle Flap

This study reviews our experience with the rectus femoris muscle flap for complex groin wound reconstruction. Over the past 5 years, the rectus femoris has become our routine method of groin wound reconstruction. The rectus femoris is harvested through a midanterior incision extending over the distal two-thirds of the thigh. The muscle is elevated on its pedicle and transposed into the groin wound defect either directly or through an intervening skin bridge. Hospital and outpatient records were reviewed for all patients undergoing groin wound reconstruction with this technique from 1999 through 2003. Thirty-seven rectus femoris muscle flaps were performed in 33 patients. The mean patient age was 65.3 years (range, 25 to 88 years). Thirty groin wounds (81.1 percent) occurred after infrainguinal revascularization, 23 (76.7 percent) of which contained prosthetic material. Five (21.7 percent) of these wounds had their prosthetic material removed at the time of reconstruction. The remaining seven groin wounds (18.9 percent) occurred after femoral vessel cannulation for either cardiac or transplant surgery. There were no intraoperative mortalities and no anastomotic hemorrhages. There were no flap losses. Thirty-five of the 37 treated wounds healed (94.6 percent), 26 primarily (70.3 percent) and nine (24.3 percent) after delayed healing and contracture. Reoperation was performed in one patient for flap readvancement and in three patients for prosthetic graft removal after initial flap reconstruction. Two patients (6.1 percent) died during their hospitalization with persistent open groin wounds after flap reconstruction. All muscle flap donor incisions healed, with only two (5.4 percent) experiencing minimal delayed healing. There were no donor-site wound infections and no donor sites required reoperation. Thirty-three groin wounds (89.2 percent) demonstrated culture-positive microbial infection, 15 (45.5 percent) of which were polymicrobial. The 30-day mortality rate was 15.2 percent and the 6-month mortality rate increased to 27.2 percent, with multisystem organ failure as the most common cause. The rectus femoris muscle flap is an effective and reliable means of complex groin wound reconstruction. The muscle flap is dependable and the donor site is not problematic, even in the presence of peripheral vascular disease. On the basis of our clinical results, we believe that the rectus femoris muscle flap is the flap of choice for groin wound reconstruction.

The versatility of free rectus femoris muscle flap: an alternative flap

In the 10-year period from June 1985 to December 1994, 54 free rectus femoris muscle or musculocutaneous flaps were performed at our hospital. It has been one of the most frequently used free muscle flaps in our institution and forms 2% of all free tissue transfers (total, 2,769 cases). In 26 patients, it was used for large wound coverage following debridement or tumor ablation, and in 27 patients, as a functioning free muscle transplantation for brachial plexus palsy or traumatic muscle loss. In one patient the components of the deep aponeurosis, muscle, and overlying skin were used for reconstruction of an abdominal wall defect after neurilemmoma excision. There were two complete failures, one due to diabetic foot infection and one due to venous occlusion. Four had superficial marginal skin necrosis. No significant disability of the donor limb was encountered. Easy approach, rapid harvest, large and reliable overlying skin flap, a single dominant neurovascular pedicle (with large vessel diameter and long motor nerve), easy primary closure of the donor site, and minimal donor site morbidity all make the rectus femoris flap a good alternative flap for free tissue transfer, in addition to the gracilis, rectus abdominis, and latissimus dorsi muscle flap.
