Medial Femoral Condyle Free Flap: A Systematic Review and Proportional Meta-analysis of Applications and Surgical Outcomes. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5708. [PMID: 38596574 PMCID: PMC11000773 DOI: 10.1097/gox.0000000000005708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 02/12/2024] [Indexed: 04/11/2024]
Abstract
Background Recalcitrant bone nonunion and osseous defect treatment is challenging and often requires vascularized bone transfer. The medial femoral condyle flap has become an increasingly popular option for reconstruction. The study aims at reviewing its different applications and synthesizing its surgical outcomes. Method A systematic review including all studies assessing surgical outcomes of free medial femoral condyle flap for bone reconstruction in adults was conducted on January 31, 2023. Flap failure and postoperative complications were synthesized with a proportional meta-analysis. Results Forty articles describing bony reconstruction in the head and neck, upper limb, and lower limb areas were selected. Indications ranged from bony nonunion and bone defects to avascular bone necrosis. Multiple flaps were raised as either pure periosteal, cortico-periosteal, cortico-cancellous-periosteal, or cortico-chondro-periosteal. A minority of composite flaps were reported. Overall failure rate was 1% [95% confidence interval (CI), 0.00-0.08] in head & neck applications, 4% in the lower limb (95% CI, 0.00-0.16), 2% in the upper limb (95% CI, 0.00-0.06), and 1% in articles analyzing various locations simultaneously (95% CI, 0.00-0.04). Overall donor site complication rate was 4% (95% CI, 0.01-0.06). Major reported complications were: femoral fractures (n = 3), superficial femoral artery injury (n = 1), medial collateral ligament injury (n = 1), and septic shock due to pace-maker colonization (n = 1). Conclusion The medial femoral condyle flap is a versatile option for bone reconstruction with high success rates and low donor site morbidity.

PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e4925. [PMID: 37035122 PMCID: PMC10079347 DOI: 10.1097/gox.0000000000004925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 02/14/2023] [Indexed: 04/11/2023]
Abstract
The medial femoral condyle free flap serves as an attractive reconstructive option for small- to intermediate-sized bony defects. It is commonly applied in the extremities with limited reports in the head and neck. Methods A systematic review of the literature was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results Seventeen articles met inclusion criteria, yielding 166 cases for analysis, with a majority of the cohort from a single study (n = 107; 64.4%). However, all included studies represented novel reconstructive sites and surgical indications. Flap components were described in 157 cases; periosteum was used only in four cases (2.5%), whereas all others are composed of cortical bone combined with periosteum, cancellous bone, and/or cartilage (97.5%). Additionally, a skin island was used in 43 cases (25.9%). Flap measurements were reported in 51 cases, averaging 4.5 ± 2.7 cm in length. Seven cases listed skin island dimensions, averaging 20.2 ± 12.8 cm2. The descending genicular artery was the primary pedicle employed (n = 162; 97.6%), while the superior medial genicular was used in the descending genicular artery's absence (n = 4; 2.4%). Descending genicular artery pedicle length from 15 reporting cases averaged 6.4 ± 1.2 cm. Successful reconstructions totaled 160 cases (96.4%). Recipient complications were seen in 16 cases (9.6%) with six constituting flap failures (3.6%). Donor site complications were minimal (n = 6; 3.6%); however, this included one major complication of femoral shaft fracture. Conclusion The medial femoral condyle free flap is an effective reconstructive option for the head and neck due to its versatile nature, low complication profile at both recipient and donor site, ease of harvest, and two-team approach.

Abstract
SUMMARY The medial femoral condyle flap is well-described for reconstruction of small bone defects of the upper and lower extremities. There are limited case reports of its use in other anatomic sites, particularly for reconstruction of complex head and neck defects. In the setting of previous radiation and contaminated fields, vascularized bone is generally preferred to bone grafts, cadaveric allografts, or synthetic implants. The authors present a case series of complex craniofacial defects involving the midface that were reconstructed using medial femoral condyle flaps, focusing on the type of defect and lessons learned from their early experience to promote awareness of this flap among microsurgeons, who may wish to consider the potential of this flap and incorporate its use into their armamentarium. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

A non-randomized clinical trial. Head Face Med 2022; 18:38. [PMID: 36461049 PMCID: PMC9716850 DOI: 10.1186/s13005-022-00342-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 10/20/2022] [Indexed: 12/03/2022] Open
Abstract
The aim of this study was to evaluate the efficacy of the retromandibular approach (RMA) to produce three-dimensional (3-D) reduction of the unilateral subcondylar fracture and Temporomandibular Joint (TMJ) functional implication. METHODS A prospective cohort study was designed. Twenty-nine patients with unilateral subcondylar fracture underwent consecutively Open Reduction, and Internal Fixation. The cohorts were divided into two groups; RMA group (n = 16, 55.17%) and submandibular approach SMA group (n = 13, 44.82%). The primary outcome was the anatomical 3-D reduction of the condyle. The secondary outcome was to compare the condyle position and inclination finding with TMJ outcomes. Helkimo Index score was used to evaluate the TMJ outcome at six months postoperatively. RESULT There was a significant difference between the mediolateral condylar inclination, condylar medial and vertical positions when RMA compared with SMA groups (P < 0.05). The medial joint space was correlated with the medial condylar position in both groups (P < 0.05). The Helkimo Ai and Di was associated with mediolateral condylar inclination in SMG; however, Helkimo Ai was found to be correlated with the RMA group. CONCLUSION The current study demonstrates that the RMA could re-establish the anatomical position of the unilateral subcondylar fracture in patients undergoing ORIF. The clinical outcome of the TMJ with RMA was better than SMA.

Utilization of a Chimeric Medial Femoral Condyle Free Flap for Mandibular Osteoradionecrosis. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2022; 10:e4489. [PMID: 36032378 PMCID: PMC9400941 DOI: 10.1097/gox.0000000000004489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Accepted: 06/27/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Primary options for oromandibular reconstruction with osteocutaneous free flaps are the vascularized fibula and iliac crest. Complications of mandible reconstruction are not uncommon and include osteomyelitis, malunion, and osteoradionecrosis (ORN) after radiation therapy. The medial femoral condyle (MFC) free flap is an established salvage option for carpal reconstruction in hand surgery, frequently used for scaphoid nonunion and avascular necrosis. We hypothesize that the MFC flap can be utilized to restore blood supply and reverse the negative effects of radiotherapy in patients who require mandibular reconstruction due to ORN. METHODS A retrospective chart review was conducted at Beaumont Health System, Royal Oak, for patients who underwent MFC free flap reconstruction for mandibular ORN between the years 2012 and 2018. Demographic data, operative details, complications, medical comorbidities, and patient outcomes were retrospectively gathered. RESULTS A total of four patients were isolated. Four patients developed ORN after resection of squamous cell carcinoma and adjuvant radiotherapy. No patients experienced donor site deficits. Revisions after MFC reconstruction were dependent on individual aesthetics and involvement of neighboring tissue. All four patients continue to be followed with no current issues to the osseous component of the MFC flap. CONCLUSION Utilization of the MFC periosteal flap is a viable option in selected patients to salvage nonunion/resorption of mandible reconstruction and ORN of the mandible. Our experience found that the MFC is able to provide pain resolution and healing of intraoral soft tissue defects, and may halt the progression of ORN of the mandible.

Abstract
In association with major amputations of the upper and lower extremities, surgical procedures with nerve transfer are increasingly being introduced. In order to examine the value of these procedures the currently available data were analyzed and related to the corresponding insights from conventional amputation surgery as well as confirmed aspects of microsurgery of peripheral nerves. Mainly retrospective observations of low case numbers and sometimes individually different surgical approaches can be found. Risk analysis and sufficient long-term follow-up periods are lacking as well as comparisons with appropriate control groups. The published results on operative procedures with selected nerve transfers after or during amputation do not currently allow any conclusions about the advantages. Systematic influences in the assessment of the results are probable. Implementation of these treatment options outside controlled clinical trials cannot be recommended.
