Successful management of recalcitrant infection related to total hip replacement using pedicled rectus femoris or vastus lateralis muscle flaps

Gluteus maximus transfer for wound closure and treatment of abductor deficiency: a single-plastic surgeon series

INTRODUCTION

Due to the increasing number of total hip arthroplasties (THA), the number and complexity of revision procedures are also on the rise. For complex cases such as periprosthetic joint infections with soft tissue compromise or for abductor muscle deficiencies, one of the treatment options is a gluteus maximus flap (GMF) that covers dead space and can help restore the failed abductor mechanism. The purpose of this study is to investigate the outcomes of a single-plastic surgeon's series of GMF procedures.

MATERIALS AND METHODS

This retrospective review reports on 57 patients (mean follow-up 39.2 months) undergoing GMF transfers for abductor insufficiency on native hip (N = 16), for abductor insufficiency in aseptic revision THA (rTHA) (N = 16), for soft tissue defects in aseptic rTHA (N = 8) and for soft tissue defects in septic rTHA (N = 17) by a single plastic surgeon over a 10-year period. Revision-free survival and complication rates were assessed and risk factors were analyzed with Cox-regression analysis.

RESULTS

The reoperation-free survival rate of GMF for abductor insufficiency in native hips was 100%. GMF procedures for soft tissue defects in septic rTHA had the lowest cumulative revision-free survival (34.3%) and highest reinfection rates (53.9%). More than three prior surgeries (HR = 2.9, p = 0.020), presence of infection (HR = 3.2, p = 0.010) and resistant organisms (HR = 3.1, p = 0.022) significantly increased the risk of revision.

CONCLUSIONS

GMF is a viable option for addressing abductor insufficiency in native hip joints. However, high revision and complication rates are reported for GMF in septic rTHA. This study highlights the need to clarify the circumstances for which the flap reconstruction will be indicated.

Covering of wound infection in hip arthroplasty with local cutaneous flaps

Total hip arthroplasty is a very common procedure to treat osteoarthritis. One of the complication is the infection which occurs in about 1% of the cases. The manifestation of infection can be poor wound healing with dehiscence and exposition of bone or prosthetic components. Hip arthroplasty infections are difficult to treat. It required an associated multidisciplinary approach with infectiology, orthopedic and plastic surgeries. The study included five patients with hip wound dehiscence after total hip arthroplasty. Coverage after orthopedic surgery was provided by local cutaneous flap. These cutaneous flaps were either a deep inferior epigastric perforator flap (DIEP) or a transposition flap. The orthopedic and the plastic treatment were done at the same time. Two deep inferior epigastric flaps were performed for patients with a deep defect with bone or prosthesis exposure. Four transposition flaps were done in three patients with wound dehiscence but without direct contact with the prosthesis. Three transposition flaps were done from the abdominal wall and one from the posterior thigh. The mean follow up was 18 months, ranging from 10 to 24months. After healing, there was no recurrence of the infection. In all cases, the coverage was obtained. The prosthesis was salvage and the gait was possible. Cutaneous flaps are easy and safe to cover the hip. They are reliable flaps even in patients with multiple co-morbidities. They do not cause sequelae on the recipient site. This study is the first about cutaneous flap for covering hip defects in hip arthroplasty infections.

Vastus lateralis vs rectus femoris muscle flaps for recalcitrant hip joint infection: an anatomical study comparing the effectiveness of acetabular dead space control

Eliminating recalcitrant prosthetic hip joint infections remains one of the greatest challenges in orthopedic surgery. In such cases, the salvage procedure of femoral head excision (the Girdlestone procedure) is often performed. There has been emerging surgical interest in filling the resulting acetabular dead space with a pedicled muscle flap, to enable antibiotic delivery. Both vastus lateralis (VL) and rectus femoris (RF) muscle flaps have been described for this purpose with good success. This study is the first anatomical investigation comparing VL and RF as candidates for interposition myoplasty following hip joint excision. Following standard surgical technique, the Girdlestone procedure and interposition myoplasty of both RF and VL were performed on 10 cadavers. The primary aim was to determine which muscle flap eliminated a greater volume of acetabular dead space. Secondary aims were to characterize the blood supply to RF and assess additional metrics indicative of the likelihood of flap success. The VL flap eliminated more dead space than RF. However, the use of the RF flap was feasible in all cases and has several benefits, including ease of harvest, mobility, and aesthetics. The location of the inferior vascular pedicle into RF was relatively consistent and the most effective predictor of flap success. Both VL and RF are effective in reducing acetabular dead space. While VL can fill a greater volume, the RF flap has technical advantages, related to the predictability of the blood supply.

Use of muscular flaps for the treatment of hip prosthetic joint infection: a systematic review

BACKGROUND

Deep periprosthetic infection after total hip arthroplasty (THA) is a serious and challenging complication for the orthopedic surgeon. Muscular flaps may represent a valid management option for the treatment of this condition. We present a systematic literature review about the use of muscular flaps for the treatment of hip prosthetic joint infection.

METHODS

The review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Seventy-seven articles, out of 279 titles, were considered eligible for the full-text analysis. Finally 15 studies that met inclusion criteria were included in this review.

RESULTS

Overall, 210 patients (49% males, 48.6% females and 2.4% not reported) suffering from THA infection treated with muscular flaps were collected. The mean age was 69.6 years. Mean follow-up, reported in all studies, was 3.3 years. The results presented by the different authors, highlight the effectiveness of muscular flaps for the treatment of periprosthetic infection, in terms of function, limb salvage, prevention of the recurrences, cost-effectiveness, and quality of life postoperatively.

CONCLUSIONS

Muscle flaps provide an excellent management option for patients with persistent infection after total hip arthroplasty.

[A pedicled deep inferior epigastric flap to cover a hip arthroplasty infection]

The deep inferior epigastric perforator (DIEP) flap is a reliable flap mostly used in skin resurfacing after signifiant resection for sarcoma or correction contour deformities. This case is about a pedicled DIEP flap covering the trochanteric region after a total hip arthroplasty infection. A 62years old woman with a BMI at 42kg/m² presents an infected total hip arthroplasty with a cutaneous defect. The hip prosthesis is changed and covered with a pedicled DIEP flap. This original case reports the used of pedicled DIEP flap in hip coverage. This local fasciocutaneous flap covered the hip osteoarticular infection. The limb is salved and the patient can walked again. The success of this surgery is the collaboration between infectious disease specialist, orthopedic surgeon and plastic surgeon.

Total Hip Arthroplasty for Ankylosis Requiring Rotational Rectus Femoris Flap and Skin Graft for Wound Closure

We present a case report of a 51-year-old Ghanaian immigrant who underwent total hip arthroplasty in the setting of spontaneous ankylosis of unknown etiology. The increase in offset of the patient's limb through reconstruction, in combination with severe soft-tissue atrophy of the lower extremity, resulted in a soft-tissue defect that could not be closed primarily. This ultimately required a rectus femoris rotational flap and skin grafting for coverage. We describe the surgical technique used for conversion of an ankylosed hip to total hip arthroplasty, as well as the technique for management of a large proximal thigh soft-tissue defect with rectus femoris muscle flap coverage.

[Resection Arthroplasty Using a Vastus Lateralis Muscle Flap in the treatment of patients with recurrent form of the hip prosthetic joint infection]

OBJECTIVE

To evaluate the efficacy of chronic recurrent hip periprosthetic joint infection (PJI) eradication after resection arthroplasty with non-free transplantation of vastus lateralis muscle flap of the thigh.

MATERIAL AND METHODS

There were 38 patients with chronic recurrent hip PJI who underwent resection arthroplasty with non-free transplantation of vastus lateralis muscle flap of the thigh in 2005-2016. The groups were compiled considering the absence or presence of recurrent infection in early postoperative period. Infection duration, number of operations, incidence of recurrent PJI, type of pathogen, laboratory parameters, bone defect size and presence of PJI remission within at least 2 years were investigated.

RESULTS

Uneventful early postoperative period after resection arthroplasty with non-free transplantation of vastus lateralis muscle flap was noted in 81.6% of cases (n=31, group 1). Postoperative wound revision was required in 18.4% of cases (n=7, group 2). Stable remission of infection within 2-8 years (Me - 4 years) was achieved in 36 (94.7%) patients. Relative risk of recurrent PJI increased by more than 4 times (RR 4,364, 95% CI 0,581-32,787) in cases of polymicrobial infection involving Gram-negative bacteria and decreased in cases of monomicrobial infection (RR 0,256, 95% CI 0,034-1,916). Significantly longer duration of surgery and more pronounced laboratory changes were revealed in group 2.

CONCLUSION

High efficacy of resection arthroplasty with non-free transplantation of vastus lateralis muscle flap of the thigh was established in patients with chronic recurrent hip PJI. This procedure might be considered as a stage treatment with the possibility for revision arthroplasty in case of failed initial debridement surgery due to PJI pathogens that are difficult for eradication.

A cadaveric analysis of the blood supply to rectus Femoris

BACKGROUND

Rectus femoris is a versatile muscle frequently used as a pedicled flap in reconstructive surgery. The anatomy and blood supply of rectus femoris needs to be clearly understood in order to safely preserve its reconstructive and functional capabilities. Classical anatomical description states that the proximal pedicle insertion into rectus femoris is 10- 15 cm from the anterior superior iliac spine (ASIS). The aim of this study was to dissect and identify the pedicular blood supply to rectus femoris and further map its morphology relative to the ASIS.

METHODS

A dissection of 20 embalmed thighs from 10 cadavers was conducted. The distance of arterial insertions into rectus femoris from the ASIS were recorded. The cohort was 60% male of median age 79 with statistical significance defined as p < 0.05.

RESULTS

5%, 50%, and 45% of muscles demonstrated 1, 2, and 3 pedicles respectively. The mean distance from the ASIS to insertion of these pedicles was: proximal 13 cm (SD 2.6), middle 15 cm (SD 2.8), and distal 18 cm (SD 4.1). When grouped by number of pedicles, there was no difference in the mean height of proximal insertion. However, there was significant difference in mean intramuscular proximal-distal difference. These results were replicated when data were expressed as % of cadaver height.

CONCLUSIONS

This study confirms the pedicular supply of rectus femoris but in contrast to classical literature demonstrates a greater range of pedicle insertions heights. We believe these observations should be considered when safely harvesting the pedicled rectus femoris flap.

A Devasting Course of an Iliopsoas Muscle Abscess Subsequently Leading to Septic Shock, Septic Hip Arthritis, and Extended Gluteal Soft Tissue Necroses in an Elderly Immunocompromised Patient with Multiple Carcinomas: A Case Report and Brief Review of Literature

BACKGROUND

A devasting course of Iliopsoas Muscle (IPM) abscess remains a challenging therapeutic problem.

METHODS

A 69-year-old polymorbid male had a history of multiple carcinomas and presented with advanced stage of septic shock due to a right IPM abscess which communicated with the right hip joint and subsequently led to septic hip arthritis accompanied with post-infectious right gluteal deep soft tissue necroses. Management of surgical treatment included abscess revision, coverage with the use of Long Head Biceps Femoris Muscle (LHBFM) 180° turnover flap, and creating a Girdlestone resection-arthroplasty.

RESULTS

After a duration of patient's hospitalization of six months that included the necessity of artificial respiration over two months accompanied with in summary 18 required surgical procedures, the patient could be recovered successfully regarding his polymorbidity and his low-demand claims in activities of daily living with his Girdlestone resection-arthroplasty.

CONCLUSION

Recovery of immunocompromised patients with those life-threatening situations can only be achieved by an interdisciplinary management. The LHBFM 180° turnover flap can be useful for filling off post-infectious deep soft tissue cavities communicating with the hip joint. The definitive Girdlestone resection-arthroplasty for treatment of septic hip arthritis is the method of choice for mobilization of elderly polymorbid patients with low demand claims in their activities of daily living.

Gluteus Maximus Advancement Flap Procedure for Reconstruction of Posterior Soft Tissue Deficiency in Revision Total Hip Arthroplasty

The current study describes the surgical technique and early outcomes of a gluteus maximus advancement flap procedure for the treatment of posterior soft tissue insufficiency among patients with complex revision total hip arthroplasty. This retrospective case series was conducted with a prospective, single-institution arthroplasty registry. Patients who underwent a gluteus maximus advancement flap procedure in the setting of revision total hip arthroplasty between January 2012 and January 2016 were eligible for inclusion (N=7). Primary indications for the gluteus maximus flap procedure included periprosthetic infection with persistent wound breakdown (n=4), persistent symptomatic aseptic pseudotumor in the setting of adverse local tissue reaction after unsuccessful operative debridement (n=2), and abductor insufficiency with recurrent hip instability after unsuccessful placement of a constrained liner (n=1). All patients who underwent a gluteus maximus advancement flap procedure for chronic periprosthetic infection or adverse local tissue reaction had healing of the wound and were infection-free at the last follow-up. In the early postoperative period, 2 patients had recurrent wound infection that required flap elevation. The patients remained infection-free after the subsequent procedure. No patient had repeat instability, and no complications of flap necrosis or nerve palsy occurred. The gluteus maximus advancement flap procedure provides a diverse range of soft tissue coverage options for patients with recalcitrant periprosthetic joint infection, adverse local tissue reaction with pseudotumor, or recurrent instability.

Orthopedic Prosthetic Infections: Plastic Surgery Management

Orthopedic prosthetic infections are potentially devastating complications. Plastic surgeons are frequently consulted to aid in the management of the soft tissue defects that are created by these infections. A review of the existing literature was performed to identify established treatment methods for soft tissue coverage of orthopedic hardware infections for a variety of anatomic locations. The following treatment guidelines and soft tissue reconstructive options were identified as viable options for the management of exposed or infected orthopedic hardware. This review provides descriptions of the various soft tissue reconstructive options available as well as adjunctive treatment methods.
