Incidence and Risk Factors for Secondary Surgery and Amputation After Lower Extremity Limb Salvage.

Traumatic defects of the lower extremity (LE) require robust soft tissue to cover critical structures and facilitate healing. Free tissue transfer (FTT) is often necessary when local tissue is inadequate. While much of the literature emphasizes free flap viability in successful limb salvage, there is limited understanding regarding the need for additional surgeries or eventual amputation. We investigated a single institution's limb salvage efforts to better understand the need for additional procedures. All patients who underwent LE limb salvage were retrospectively reviewed from 2014 to 2022 at a single level 1 trauma center. Our primary clinical outcome was the incidence and indication of secondary surgeries following FTT. Ninety-two LE free flaps were performed during the study period. The mean age was 45 and majority were male. Seventy-two percent of flaps were fasciocutaneous while 28% were muscle flaps. Seventy-two percent of patients required a secondary surgery following FTT, with a mean of 7 total surgeries per salvage attempt. Ten percent of patients proceeded to amputation. Body mass index >30, higher frailty scores, flap type, and masquelet technique were significantly associated with subsequent amputation (P = 0.017, P = 0.024, P = 0.005, P = 0.04, respectively). Older age, the need for bony reconstruction, and longer period from injury to flap coverage were significantly associated with the need for secondary surgeries (P = 0.05, P < 0.001, and P = 0.22 respectively). FTT is an important component of limb salvage. Patients undergoing limb salvage should be counseled on the need for secondary surgeries, as the process is often not complete following FTT. Furthermore, risk factors identified in this study may increase the likelihood of subsequent amputation. Thorough preoperative counseling is necessary to optimize the postoperative course and expectations in this population.

Open Posterior Capsular Reconstruction Using Acellular Dermal Allograft

Posterior shoulder instability accounts for a minority of shoulder instability cases. There is a lack of data and treatment algorithms compared to anterior shoulder instability; moreover, many of the proposed techniques focus on bony reconstruction. We describe an open technique of capsular reconstruction in the absence of glenoid bone loss using dermal allograft tissue secured with knotless fixation. This technique offers the advantage of direct visualization of graft placement and simplifies suture management.

Pelvic and Perineal Reconstruction.

After studying this article, the participant should be able to: 1. Classify types of bony pelvic resections. 2. Outline reconstructive options for pelvic and perineal defects. 3. Identify advantages and drawbacks of various reconstructive techniques. 4. Recognize the functional benefits of bony and soft-tissue reconstruction. Defects of the pelvis and perineum arise from tumors, trauma, infection, congenital differences, and gender incongruence. Pelvic resections can result in bony instability and soft-tissue deficiency. The goals of reconstruction are maintenance of spinopelvic continuity, elimination of dead space, resurfacing of cutaneous defects, and prevention of hernias. Perineal reconstruction has important functional considerations. Abdominoperineal resection and pelvic exenteration defects benefit from flap reconstruction to decrease pelvic wound complications. Vulvovaginal reconstruction is performed with flaps from the perineum, thigh, or abdomen. Scrotal and superficial penile defects are most commonly reconstructed with scrotal flaps and skin grafts. Total penile reconstruction most commonly uses a radial forearm free flap.

Do Adductor Tenotomies Prevent Progressive Migration in Children with Cerebral Palsy?: A Systematic Review.

Up to one-third of children with cerebral palsy (CP) develop migration of the hip, and the risk increases with a higher Gross Motor Function Classification System (GMFCS). In progressive hip migration in young children, adductor tenotomy is an accepted treatment option to delay or prevent progressive hip migration. However, there is quite a large variability in reported results. This systematic review aims to determine the effectiveness of a soft-tissue release in the prevention of progressive hip migration in children with CP. This systematic review was performed in accordance with the guidelines of the Cochrane Handbook for Systematic Reviews and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statements. Our inclusion criteria were studies describing pediatric, skeletally immature patients with CP and a "hip at risk" of progressive hip migration. Exclusion criteria were simultaneous bony reconstructions, case reports, technical notes, published abstracts, or studies with a follow-up under 1 year postoperatively. The primary outcomes were defined as failure rate (progressive hip migration and/or need for bony surgery, as defined by each paper) and change in migration percentage (MP) at final follow-up. As secondary analyses, we evaluated the outcome after specific subtypes of surgeries and assessed whether performing lengthening of iliopsoas, neurectomy of the anterior branch of the obturator nerve, age at the time of surgery, GMFCS level, and postoperative management impact the outcome. Our literature search identified 380 titles. Eighty-four articles underwent full-text review, of which 27 met our inclusion/exclusion criteria and were subsequently selected for quantitative analysis. A prevalence meta-analysis was performed including 17 studies (2,213 hips). Mean follow-up ranged from 12 to 148.8 months. The mean preoperative MP was 33.4% (2,740 hips) and 29.9% at follow-up. The overall reported failure rate was 39% (95% confidence interval, 26%-52%). Performing a release of only adductor longus had a failure rate of 87%, whereas more extensive soft-tissue releases showed significantly better results with failure rates ranging from 0 to 44% (p < 0.001). Lengthening of the iliopsoas had no significant impact on failure rate (p = 0.48), nor did performing an obturator neurectomy (p = 0.92). The failure rate of adductor tenotomies to prevent progressive hip migration appears to be as high as 39% in studies with a varying follow-up. The failure rates are significantly higher when isolated release of the adductor longus is performed. This systematic review supports clinical decision making in children with CP and early hip migration. Level IIA. See Instructions for Authors for a complete description of levels of evidence.

Impact of Preoperative Multidisciplinary Conference on Head and Neck Reconstruction Outcomes.

Head and neck oncologic resections with microvascular reconstruction are lengthy and complex procedures with inefficiencies in the operating room (OR) associated with increased complications and higher costs. Multidisciplinary care has become increasingly used to provide improved care for complex patients; however, the potential role of this has not yet been studied in head and neck microvascular free flap procedures. Patients between 2016 and 2022 treated before and after implementation of the conference were included. Primary outcome was total procedure time (TPT). Demographics, operative details, and postoperative complications were also collected. 233 patients were included in the preconference group and 330 in the post-conference group. Preconference mean (SD) age was 61.6 (12) years versus 62.9 (12) years in the post-conference group. The post-conference group was associated with shorter mean (SD) TPT (629 [117] vs. 719 [134] minutes), less mean (SD) estimated blood loss (ESD) (230 [201] mL vs. 306 [211] mL), fewer prolonged lCU stays (>1 day), and fewer returns to the operating room (RTOR). The post-conference group was associated with TPT ≤9 h (p < 0.001) on multivariate analysis. Factors associated with TPT greater than 9 h include history of head and neck radiation (p = 0.003), bony reconstruction (p = 0.05), stage IVa (p = 0.009), and stage IVb cancer (p < 0.001). Implementation of the multidisciplinary conference in head and neck surgery was associated with reduced TPT and reduced OR return. Our study suggests preoperative planning conferences may improve surgical efficiency and outcomes in head and neck oncologic resections with microvascular free flap reconstruction. 3 Laryngoscope, 2024.

Osseous Maxillary Reconstruction with Immediate Dental Implant Placement: An Optimized Workflow for the Oncologic Patient.

Maxillary reconstruction is a complex undertaking characterized by a 3-dimensional surgical site with deficiencies in multiple tissue types. Prior to virtual surgical planning(VSP), bony reconstruction was inaccurate and inefficient, thus reconstructions defaulted to soft tissue flaps or obturators. The current study describes an efficient and accurate approach to bony maxillary reconstruction with immediate dental implant placement(IDIP). A reconstructive workflow was developed for osseous reconstruction to improve functional and aesthetic outcomes. Critical aspects include VSP, 3-D printed plates and IDIP. Review of a prospectively maintained database identified patients who underwent osseous maxillary reconstruction with a fibula flap and immediate dental implants from 2017-2022, with a focus on oncologic characteristics and reconstructive outcomes. During the study, 20 patients underwent maxillary reconstruction with VSP and IDIP. One dental implant out of 55 failed to osseointegrate and no flaps were lost. Three patients suffered partial loss of the fibula skin island; one required palatal closure with a radial forearm flap, and two were managed with outpatient debridement. Fifteen patients achieved either an interim or final retained dental prosthesis. All prostheses achieved acceptable aesthetic results without the instability associated with non-bone borne devices(e.g.dentures/obturators). No patients experienced delays in oncologic treatment. VSP technology has enabled surgeons to replace like with like to achieve better outcomes with acceptable morbidity for maxillary defects. IDIP provides all patients an opportunity for a fixed prosthesis even though not all complete the process. This maxillary reconstruction workflow can be safely accomplished in oncologic patients with promising and effective early results.

The Chimeric LFC and DCIA Flap in Combined Mandibular and Condylar Head and Neck Reconstruction-A Case Series.

Background: Defects of the ascending ramus of the mandible, including the condylar head and neck or the whole temporomandibular joint (TMJ), are difficult to reconstruct. Reconstruction is mainly based on the use of alloplastic joint prosthesis, costochondral grafting, distraction osteogenesis of the dorsal part of the mandibular ramus, or osseous microvascular flaps of various origin. With the objective of developing a method that overcomes the restrictions of these methods, we recently introduced a sequential chimeric flap consisting of a lateral femoral condyle flap (LFC) and deep circumflex iliac artery flap (DCIA) for reconstruction of up to half of the mandible and the condylar head and neck. Methods: The chimeric flap was used in four patients with the following diagnoses: therapy-refractory osteomyelitis, extended recurrent odontogenic keratozyst, Goldenhar syndrome, and adenocarcinoma of the parotid gland. After a diagnostic workup, LFC and DCIA flaps were harvested in all patients and used in a sequential chimeric design for the reconstruction of the mandibular body and condylar head and neck. Results: Follow-up from at least 24 months up to 70 month after surgery showed a successful reconstruction in all four patients. The LFC provided a cartilaginous joint surface, allowing for a satisfactory masticatory function with a stable occlusion and unrestricted mouth opening and preserved or regained lateral and medial excursions in all patients. The DCIA allowed for a bony reconstruction anatomically resembling a non-atrophied mandibular body. No flap-related complications were observed. Conclusions: The sequential chimeric LFC and DCIA flap is an appropriate method for reconstructing up to half of the mandible and the condylar head and neck. It is suitable in cases where alloplastic joint replacement cannot be used or where other methods have failed. Due to the necessity of harvesting two flaps, the burden of care is increased, and a careful indication is required. The technique is reserved for maxillofacial surgeons who have already gained significant experience in the field of microsurgery.

The impact of zygomatic buttress bone graft on nasal floor augmentation in unilateral alveolar cleft patients with late referral: A case series

PurposeThis preliminary study aimed to assess the efficacy of zygomatic buttress bone grafting for nasal floor augmentation in patients with a unilateral alveolar cleft who were referred after the optimal timetable for this surgery had elapsed. Case seriesFive patients, aged 12–18 years, with unilateral alveolar clefts were treated at Qaem Hospital, Mashhad, Iran. Initially, a mucous layer was established on the side of the cleft nose, followed by forming a bony bridge between the defect's sides through a bone graft derived from the zygomatic buttress and xenograft bone powder. Subsequently, the grafted region was covered with an absorbable collagen membrane, and the oral-side flap was sealed. Post-operative follow-ups occurred at 1 week, 1 month, and 3 months, and cone beam computed tomography (CBCT) was performed 6 months post-treatment. Discrepancy between the anterior edge height of the pyriform aperture on the healthy and cleft sides post-grafting was assessed. The average disparity between the height of the anterior edge of the pyriform aperture on the healthy side and the peak height achieved post-grafting on the cleft side was 1.90 ± 2.82 mm. ConclusionWithin the limitations of the study, it seems that zygomatic buttress is applicable for late unilateral alveolar bone grafting as an intraoral source, and is helpful in symmetric bony nasal floor reconstruction, with a good success rate.

Bony reconstruction after internal hemipelvectomy: A retrospective analysis of 44 patients undergoing femoro-pelvic pseudoarthrosis.

e23509 Background: After acetabular resection for sarcomas, achieving a bony femoro-pelvic fusion is very difficult, and prosthetic reconstructions have very high complication rates. We reconstructed the defects with a simple polypropylene mesh between the femoral head and the remaining part of the pelvis thereby aiming at a pseudo-arthrosis and analyzed its functional outcome. Methods: Between 2013 and 2022, 44 patients having bone tumors of the pelvis underwent acetabular resections and femoro-pelvic pseudoarthrosis. Commonest Histology was chondrosarcoma (23). According to Enneking’s classification, type II (3), type I+II (9) , type II+III (24), type I+II+IV (5), and type I+II+III (3) resections were carried out. A 30 x 30 cm polypropylene mesh was tied to the remains of the capsule around the head and was then turned on itself to make a strong braided rope-like structure. It was passed through the remaining ilium/ ischium/ sacrum and was tied to itself in proper rotation with heavy ethibond suture. In 4 cases, a proximal femur megaprosthesis and in 2, a nail cement spacer was implanted in femur to reduce shortening. Functional limb results were reported according to MSTS functional scores. Results: 37/44 patients attained independent ambulation. The mean time to full weight bearing was 4.7 months (3-9 months). There were 6 flap necrosis, 3 infections, 1 nerve injury, and 1 vascular injury. Local recurrence occurred in 6 (13%) and Systemic metastasis developed in 20 patients (47% of malignant tumors). At an average follow-up of 56 months ( 24 – 127 months), 26 are alive without any signs of disease. The average MSTS score was 22 (range 13–27). The best MSTS scores were with type II or II+III IH where ilium was left to support the femur while the worst was with type I+II+III resection patients. Patients with higher BMI have poorer functional outcomes with meshplasty. Conclusions: Mesh-pseudoarthrosis is a very simple reconstruction option that has an excellent functional outcome. It reduces surgical time and eliminates uncertainties about fusion/joint replacement. This should be strongly recommended as a method of reconstruction for patients undergoing acetabular resections.

Latarjet operation carries three times the risk of failure in seizure versus non-seizure recurrent anterior dislocation of the shoulder joint: outcome of a systematic review with meta-analysis.

Recurrent anterior shoulder dislocation (RASD) in cases of seizure disorders (SDs) total 50%-80% of all SD-associated shoulder instabilities. Based on the extent of bone loss, treatment options include bony and soft-tissue reconstructions, arthroplasty, and arthrodesis. The primary objective of this paper was to review the treatment options for RASD in SDs. Several bibliographic databases were searched for RASD treatment options in SD patients. The demographic outcome measures, the failure rate (defined as the relative risk of recurrence of dislocation postoperation), and the postoperative seizure recurrence rate were recorded. We pooled 171 cases (187 shoulders) from 11 studies. Of these, one, five, two, two, and one reports studied Bankart's operation with remplissage (27 cases/29 shoulders), the Latarjet procedure (106/118), bone block operation (21/23), arthroplasty (11/11), and arthrodesis (6/6), respectively, in treating SD-associated RASD. The relative risk of failure between SD and non-SD patients was 3.76 (1.3610.38) after the Latarjet operation. The failure rates were 17% and 13% for Bankart's operation with remplissage and the Latarjet procedure in SD patients, respectively, but 0% each for bone block operation, arthroplasty, and arthrodesis. The total rate of seizure recurrence after operation was 33% of the pooled cases. SD recurrence in the postoperative period, the size of the bone block, and the muscular attachments to a small coracoid autograft are the determinants of failure among various reconstructive operations in SD-associated RASD. Level of evidence: III.

Medial Femoral Condyle Free Flap: A Systematic Review and Proportional Meta-analysis of Applications and Surgical Outcomes

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 &amp; 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.

Superior orbital fissure narrowing and tumor-associated pain in spheno-orbital meningiomas.

Spheno-orbital meningiomas (SOMs) represent a distinct subtype of meningioma characterized by their unique multi-compartmental invasion pattern. Previous studies have investigated correlations between SOMs and visual manifestations. However, our comprehension of pain associated with SOMs remains limited. This study aims to provide insight into the pathophysiology underlying SOM-related pain through measurements of tumor volume and superior orbital fissure (SOF) narrowing. This retrospective study included patients who underwent surgical resection of a SOM between 2000 and 2022. Preoperative CT and/or MRI scans were analyzed, and the tumor volume of each segment was measured. Bony 3D reconstructions were used to measure the area of the SOF, and SOF narrowing was calculated. The study cohort included 66 patients diagnosed with SOMs, among which 25.8% (n = 17) presented with pain. Postoperatively, 14/17 (82.4%) of patients reported pain improvement. There was no significant correlation between the total volume or the volume of tumor within each compartment and the presence of pain on presentation (p > 0.05). The median SOF narrowing was significantly different between patients presenting with and without tumor-associated pain with median of 11 mm2 (IQR 2.8-22.3) and 2 mm2 (IQR 0-6), respectively (p = 0.005). Using logistic regression, a significant correlation between the degree of SOF narrowing and the presence of SOM-associated pain on presentation was identified, with an aOR of 1.2 (95% CI 1.12-1.3, p = 0.02). While the exact cause of tumor-associated pain remains unclear, SOF narrowing seems to play a role in pain among SOM patients. Based on the radiological characteristics, SOF neurovascular decompression is recommended in SOM patients.

The Perfect Timing-Immediate versus Delayed Microvascular Reconstruction of the Mandible.

In this retrospective study, the clinical and economic implications of microvascular reconstruction of the mandible were assessed, comparing immediate versus delayed surgical approaches. Utilizing data from two German university departments for oral and maxillofacial surgery, the study included patients who underwent mandibular reconstruction following continuity resection. The data assessed included demographic information, reconstruction details, medical history, dental rehabilitation status, and flap survival rates. In total, 177 cases (131 male and 46 females; mean age: 59 years) of bony free flap reconstruction (72 immediate and 105 delayed) were included. Most patients received adjuvant treatment (81% with radiotherapy and 51% combined radiochemotherapy), primarily for tumor resection. Flap survival was not significantly influenced by the timing of reconstruction, radiotherapy status, or the mean interval (14.5 months) between resection and reconstruction. However, immediate reconstruction had consumed significantly fewer resources. The rate of implant-supported masticatory rehabilitation was only 18% overall. This study suggests that immediate jaw reconstruction is economically advantageous without impacting flap survival rates. It emphasizes patient welfare as paramount over financial aspects in clinical decisions. Furthermore, this study highlights the need for improved pathways for masticatory rehabilitation, as evidenced by only 18% of patients with implant-supported dentures, to enhance quality of life and social integration.

Operative technique: Pectoralis major flap with rib.

The osteomyocutaneous pectoralis major flap was first described in 1980 and provides a single stage reconstructive option for poor free flap or pectoralis major flap with reconstruction plate candidates requiring bony reconstruction. The flap provides good functional and cosmetic outcomes in appropriately selected patients. We describe the indications and operative techinique for harvesting this flap in written and video format.

Direct Anterior Bone Block Grafting for Coronoid Bone Loss and Dysplasia

Background: Critical coronoid bone loss (CCBL) can be the key factor of elbow instability, making bony reconstruction essential. Coronoid bone grafting (CBG) is challenging, with a paucity of descriptions in the literature. We present direct anterior CBG in a patient with instability, CCBL (&gt;40%), lateral ulnar collateral ligament (LUCL) insufficiency, and ligamentous laxity who underwent LUCL reconstruction in the same setting. Indications: Isolated ligament reconstruction has a high failure rate in cases with CCBL and therefore requires additional bone grafting. The diagnosis of CCBL is made with lateral radiographs and further quantified by computed tomography imaging. Instability can be best assessed objectively during arthroscopy with a switching stick. CBG performed with an anterior approach facilitates direct access with advantages for plate and screw positioning and access to the proximal radio-ulnar joint. Technique Description: First, LUCL reconstruction was performed. After harvesting of the graft from the iliac crest, the coronoid was exposed with a direct anterior approach. The incision starts centrally medial to the biceps tendon (BT) in the flexion crease extending distally (9 cm). Ligation of multiple vessels (leash of Henry) is required. The deep dissection is continued between the bicipital aponeurosis and BT. Blunt and flat Langenbeck-type retractors are used with care, laterally (BT/radial nerve) and medially (aponeurosis/median nerve). The brachialis muscle is exposed and longitudinally split in line with its fibers, gaining access to the capsule. Harmful retraction on either side of the split has to be avoided. The capsule is incised as a Z-plasty, the coronoid exposed from the joint in the distal direction prior to freshening up the graft bed. The graft is held in place with a wire joystick, sculpted, and temporarily fixed. Joint congruency, stability, and a range of motion (ROM) are checked prior to definitive fixation with a 2.4-mm buttress plate and screws. Results: The coronoid process height was successfully reconstructed from &lt;60% to 100% with durable elbow stability (&gt;1 year), free ROM, and high patient satisfaction. Conclusion: CBG can be standardized and facilitated with a direct anterior approach as a key element for successful elbow stabilization in the setting of CCBL.

Effectiveness of Additive Manufactured Titanium Implants in the Reconstruction of Large Cranial Defects: Case Series and Review of Literature

Abstract Introduction Replacement of lost soft and hard tissues of the human body has always been a daunting task across all surgical specialties. Reconstruction of a cranial deformity is challenging due to the functional and cosmetic requirements. A major constraint with large cranial bony deformity reconstruction is the nonavailability of graft of a specific shape and size. Materials and Method A total of four cases of large cranial defects which included three cases of unilateral and one case of midline residual deformity were reconstructed at our center using customized titanium implants. These implants were fabricated using additive manufacturing/3D printing technology utilizing computerized tomographic data. Conclusion The additively manufactured titanium implants appear to be a viable option in the reconstruction of large cranial defects.

Virtual Surgical Planning Facilitates Surgical Resection in Mandibular Osteoradionecrosis and Optimize Reconstructive Outcomes

Background: Mandibular osteoradionecrosis (ORN) is a devastating complication of radiotherapy for oropharyngeal malignancy. Despite advancements in ORN treatment, risk of ORN recurrence remains high following surgical resection. Virtual surgical planning (VSP) for ORN treatment is an evolving application that may not only inform bony reconstruction but also therapeutic surgical margins, which remain inconclusively defined in the literature. Methods: A retrospective review was performed of 25 cases in which patients underwent VSP-guided resection of mandibular ORN followed by immediate free fibula flap reconstruction. Surgical margins of 1-cm from radiologically evident disease were taken. VSP accuracy was quantified by comparing measured anatomic parameters between the virtually planned outcomes and the final outcomes on postoperative imaging. Statistical analyses were performed to assess associations between preoperative factors and postoperative complications including ORN recurrence. Results: The mandibular body was most frequently affected by ORN in this series of patients. Among risk factors, only the presence of a preoperative orocutaneous fistula was predictive of a complication, specifically partial flap failure (β = 1.41; P = .013). Intended anatomic parameters were achieved with the exception of the intergonial distance (x difference = 0.53 cm; P = .03). Finally, there were no cases of ORN recurrence after a mean follow-up of 27.4 months. Conclusions: VSP of free fibula flaps for mandibular reconstruction following ORN is a valid tool for effecting accurate anatomical outcomes. Furthermore, we demonstrate that a 1-cm margin around radiographically evident ORN may effectively implement a curative outcome free from relapse.

Pedicled osteomyocutaneous pectoralis major flap with osseous rib harvest for salvage mandibular reconstruction: Case and technique.

In the era of free flap reconstruction, mandibular defects are routinely reconstructed with osseous free flaps, and non-free flap bony reconstruction options are limited. A patient with T4N0 mandibular squamous cell carcinoma underwent resection with fibula free flap reconstruction of a parasymphyseal to angle defect. After free flap failure due to venous congestion, the flap was explanted. He declined additional free flap reconstruction and elected to proceed with pedicled osteomyocutaneous pectoralis major with rib. In this case presentation, we discuss the technical details of harvest of this flap using the 6th rib. The pedicled osteomyocutaneous pectoralis major flap with osseous rib harvest, which is infrequently described in the literature, remains a viable option for bony reconstruction, particularly in the salvage setting.

Surgical management of Charcot foot – The advancements over the past decade

Charcot neuroarthropathy is a progressive, destructive condition leading to deformity, dysfunction and, in some cases, amputation. Much evolution has occurred over the last couple of decades in the management of Charcot foot with a focus on developing limb salvage and reconstructive techniques. The aim has been to achieve a stable plantigrade foot that remains pain and ulcer-free whilst reducing amputation rates. Soft tissue and bony reconstructions have been explored, and various modalities of fixation, including internal, external, and combined techniques, have been described and their outcomes published. Currently, no strong evidence exists which supports a particular modality of treatment, nor have there been any randomised studies to this effect, but the results are nevertheless promising. Recent studies have reported on minimally invasive techniques, the use of super construct fixation, computer-navigated deformity correction, the efficacy of techniques such as subtalar arthrodesis or tendon balancing procedures and staged deformity corrections. There is a need for more controlled and comparative studies with consistent reporting of intended outcomes to create a stronger portfolio of evidence on the surgical management of Charcot foot.

A preliminary analysis of patient reported outcomes following posterolateral mandible reconstruction: The role of flap type.

The choice of tissue type for free flap reconstruction of posterolateral mandible resections is dependent on patient and defect characteristics. We compared clinical and patient-reported outcomes following reconstruction of these defects with a soft tissue or bony free flap. A retrospective review was performed on patients who underwent posterolateral segmental mandibulectomy with immediate free flap reconstruction at MSKCC from 2006 to 2021. Outcomes of interest were patient-reported outcome measures (PROMs) assessed by FACE-Q surveys and complications at the flap recipient site. Ninety patients received a bony flap and 24 patients received a soft tissue flap. Patients reconstructed with soft tissue flaps had greater rates of composite soft tissue defects (p < 0.0001), condyle resection (p = 0.001), and peripheral vascular disease (p = 0.035). Complication rates were similar between the cohorts (p > 0.05). Bony flaps scored higher on multiple FACE-Q scales: Facial Appearance (p = 0.023) Eating/Drinking (p = 0.029), Smiling (p = 0.012), Speaking (p < 0.001), Swallowing (p = 0.012), Smiling Distress (p = 0.037), and Speaking Distress (p = 0.001). Reconstruction of posterolateral mandibular defects has a similar complication profile when utilizing a bony or soft tissue free flap. Bony flaps may perform better with respect to PROMs. Reconstructive surgeons should consider using bony flap reconstruction to achieve higher patient satisfaction and quality of life.
