Surgical debridement with muscle flap transposition and systemic teicoplanin therapy for infected hip arthroplasty

Outcomes of revision arthroplasty for hip joint infection in matched groups of HIV-positive and HIV-negative patients

BACKGROUND

Several studies reported on periprosthetic infection after primary THA in HIV-positive patients, but very few showed the results of its revision.

OBJECTIVE

The aim was to compare primary and secondary clinical outcomes after revision arthroplasty for hip joint infection in matched groups of HIV-infected and HIV-negative patients.

METHODS

Using the hospital database, thirteen HIV-positive patients (13 infected hips) and thirteen HIV-negative patients of the matched control group (13 infected hips) were identified and their records were studied retrospectively. They underwent revision surgery aimed at infection arrest and total hip replacement due to infection developed after primary THA or infected spacers. Harris Hip Score, reinfection rate, limb shortening, and definite outcomes were evaluated with Wilcoxon, Mann-Whitney, and Chi-squared tests.

RESULTS AND DISCUSSION

Spacers with antibiotics were implanted in patients of both groups at the first step of revision, except one HIV-infected patient who had resection arthroplasty. The mean follow-up was 29.4±2.7 and 33.±2.9 months for the HIV-group and control group, respectively. Three patients of the HIV-group completed two-stage revision arthroplasty versus ten patients from the control group. Re-infection rate was higher in the HIV-group. At final follow-ups, the mean HHS was significantly different (53±3.2 points in the HIV-group versus 79.14±3.1 points in the control group) along with limb length discrepancy (3.71±0.43 versus 1.4±0.32).

CONCLUSION

Both primary and secondary clinical outcomes of revision arthroplasty for hip joint infection in HIV-positive patients were significantly worse than in the matched group of HIV-negative patients. Revisions in HIV-positive group resulted in a higher reinfection rate, a small number of definite two-stage revisions, and lower functional scores.

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 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.

Risk assessment and usefulness of musculocutaneous flap transposition for recurrent septic arthritis of the hip in adults

PURPOSE

Septic arthritis of the hip joint in adults often progresses to recurrent infections that require repeated surgeries for treatment. The purpose of the present study was to assess the risk of a recalcitrant hip infection and the usefulness of musculocutaneous flap transposition.

METHODS

15 adult patients who underwent surgeries for the treatment of hip infections were retrospectively analysed. Patients who recovered from infection by undergoing arthroscopy, open irrigation, debridement, continuous irrigation, resection arthroplasty, and/or the placement of antibiotic-loaded acrylic cement were classified into Group A (n = 10). Patients who showed residual infection after multiple surgeries and ultimately recovered after undergoing musculocutaneous flap transposition were classified into Group B (n = 5). The age at onset, sex, incidence of multi-drug-resistant organisms, incidence of infection at other sites, compromising factors, peak preoperative C-reactive protein level, and period from onset to initial surgery were compared between groups.

RESULTS

There was a statistically significant difference in the period from onset to initial surgery (p = 0.024). The infections remained chronic after multiple surgeries in most patients who had complications and/or a poor general or local condition. All of the patients recovered after musculocutaneous flap transposition without the need for additional surgery and did not experience recurrence during the follow-up period in Group B.

CONCLUSIONS

Delayed diagnosis and/or treatment and compromised host caused recurrent septic arthritis of the hip in adults. Musculocutaneous flap transposition may be a useful method for the treatment of recalcitrant hip infection.

Surgical technique: vastus medialis and vastus lateralis as flap transfer for knee extensor mechanism deficiency

BACKGROUND

Loss of the quadriceps tendon, patella, and patellar tendon leaves a major anterior defect that is difficult to close and compromises knee extension strength. Gastrocnemius muscle transfer does not sufficiently cover such major defects. This paper describes a new surgical technique that addresses these defects and the results of eight cases of revision TKA managed with this new technique.

DESCRIPTION OF TECHNIQUE

The new procedure transfers the vastus medialis or the vastus lateralis and their tibial attachments or both muscles and their distal expansions combined with gastrocnemius and soleus flaps to cover major deficiencies in the anterior knee. Nine cadaver knee specimens were dissected to determine the effect of the transfer on nerve and blood supply of the muscles.

METHODS

Eight patients underwent the new procedure between 2005 and 2009. Four knees had vastus medialis transfer, two vastus medialis and vastus lateralis transfer, two vastus medialis and medial gastrocnemius transfer, and two medial gastrocnemius and medial ½ of the soleus muscle transfer. Minimum followup was 15 months (mean, 43 months; range, 15-74 months). Patients were evaluated for anterior knee pain, quality of knee closure, ROM, extensor lag, walking ability, use of assistive devices, and ability to climb stairs with the operated extremity.

RESULTS

All patients achieved closure of the knee without synovial leaks by 10 days postoperatively. Mean flexion contracture at last followup was 3° (range, 0°-7°). Mean extension lag was 22° (range, 5°-65°). Extension lag was less in those knees that included gastrocnemius or soleus muscle transfer. None of the flaps developed necrosis.

CONCLUSIONS

The vastus medialis and vastus lateralis muscles provide adequate coverage for anterior soft tissue deficits of the knee.
