Decellularized Human Dermis for Orthoplastic Extremity Reconstruction.

The reconstruction of patients who possess multi morbid medical histories remains a challenge. With the ever-increasing number of patients with diabetes, infections, and trauma, there is a consistent need for promotion of soft tissue healing and a reliable substrate to assist with every aspect of soft tissue reconstruction, as well as the loss of fascial domain. Several proprietary products filled some of these needs but have failed to fulfill the needs of the clinician when faced with reconstructing multiple soft tissue systems, such as the integument and the musculoskeletal system. In this paper we discuss the use of decellularized human dermis (DermaPure®, Tissue Regenix, Universal City, TX, USA) through which a unique human tissue processing technique (dCELL® technology, Tissue Regenix, Universal City, TX, USA) and the creation of multiple product forms have proven to exhibit versatility in a wide range of clinical needs for successful soft tissue reconstruction. The background of human tissue processing, basic science, and early clinical studies are detailed, which has translated to the rationale for the success of this unique soft tissue substrate in orthoplastic reconstruction, which is also provided here in detail.

Combined Free Flaps for Optimal Orthoplastic Lower Limb Reconstruction: A Retrospective Series.

Background and Objectives: Open fracture of the lower limb can lead to substantial bone and soft tissue damage, resulting in a challenging reconstructive scenarios, especially in presence of bone or periosteal loss, with a relevant risk of non-union. This work analyzes outcomes of using a double approach for orthoplastic reconstruction, adopting the free medial condyle flap to solve the bone defects, associated to a second free flap for specific soft tissue coverage. Indications, outcomes and reconstructive rationales are discussed. Materials and Methods: A retrospective investigation was performed on patients who underwent complex two-flap microsurgical reconstruction from January 2018 to January 2022. Inclusion criteria in this study were the use of a free femoral condyle periostal/bone flap together with a second skin-only flap. Only distal third lower limb reconstructions were included in order to help equalize our findings. Out of the total number of patients, only patients with complete pre- and post-operative follow-up (minimum 6 months) data were included in the study. Results: Seven patients were included in the study, with a total of 14 free flaps. The average age was 49. Among comorbidities, four patients were smokers and none suffered from diabetes. Etiology of the defect was acute trauma in four cases and septic non-union in three cases. No major complications occurred, and all flaps healed uneventfully with complete bone union. Conclusions: Combining a bone periosteal FMC to a second skin free flap for tailored defect coverage allowed achievement of bone union in all patients, despite the lack of initial bone vascularization or chronic infection. FMC is confirmed to be a versatile flap for small-to-medium bone defects, especially considering its use as a periosteal-only flap, with minimal donor site morbidity. Choosing a second flap for coverage allows for a higher inset freedom and tailored reconstruction, finally enhancing orthoplastic success.

Orthoplastic Reconstruction of Type IIIB Open Tibial Shaft Fractures Using Debrided, Devitalized Cortical Segments: Health-Related Quality-of-Life Outcomes.

To determine health-related quality of life (HRQoL) in patients who sustained type IIIB open tibial diaphyseal (OTA/AO-42) fractures and underwent orthoplastic reconstruction using mechanically relevant devitalized bone (ORDB) versus those who did not require the use of devitalized bone as part of their orthoplastic reconstruction. Consecutive cohort study. The study included 74 patients who sustained a type IIIB open tibial diaphyseal fracture requiring orthoplastic reconstruction over a 4-year period in a major trauma center. All patients underwent a two-stage orthoplastic reconstruction protocol, with the second stage consisting of definitive fixation and flap coverage (free fascial anterolateral thigh flap) in a single sitting. Patients were contacted at a minimum of 30 months to measure HRQoL. Patients requiring ORDB versus those who did not require the use of devitalized bone as part of their orthoplastic reconstruction. The primary outcome measure was HRQoL ascertained using Euro-Qol (EQ)-5D and Short-Form (SF)-36 scores. Thirty (n = 30) patients underwent ORDB with the remaining 44 not requiring devitalized bone as part of their reconstruction. The median age was 46.5 years [interquartile range (IQR) 29.0], with a median follow-up of 3.8 years (IQR 1.5). The median cohort EQ-5D was 0.743 (IQR 0.222), ORDB 0.743 (IQR 0.195) versus non-ORDB 0.748 (IQR 0.285), P = 0.71. The median physical component SF-36 score was 80 (IQR 50), ORDB 80 (IQR 34.5) versus non-ORDB 77.5 (IQR 58.75), P = 0.72. The median mental component SF-36 score was 80 (IQR 28), ORDB 80 (IQR 21) versus non-ORDB 80 (IQR 36), P = 0.29. In patients who sustained a type IIIB open tibial shaft fracture and who underwent a 2-stage orthoplastic reconstruction, ORDB does not seem to be associated with inferior health-related quality of life based on EQ-5D or SF-36 scores. The results of this approach should be considered within the strict combined orthoplastic approach in the study unit. Therapeutic Level III.

Acute Compartment Syndrome in Type IIIB Open Tibial Shaft Fractures Using a 2-Stage Orthoplastic Approach.

To determine the rate of acute compartment syndrome (ACS) in a series of patients with Gustilo-Anderson type IIIB open tibial shaft fractures that were treated using a specific 2-stage orthoplastic protocol. Consecutive cohort study. Ninety-three (n = 93) consecutive patients with a type IIIB open tibial shaft fracture (OTA/AO-42) treated using a 2-stage orthoplastic approach, between August 2015 and January 2018. After exclusions, 83 (n = 83) were eligible for analysis. Colloid resuscitation and 2-stage orthoplastic reconstruction of type IIIB open tibial shaft fracture. Stage 1 consists of "3-vessel view" early debridement and temporary internal fixation, with stage 2 consisting of a single-stage fix and flap. Rate of ACS. Secondary outcomes included early/late sequelae of missed ACS, deep infection, arterial injury, nonunion, and flap failure. Eighty-three (n = 83) patients were included for analysis. The median age was 45.4 years [interquartile range (IQR) 35] with a median follow-up of 1.6 years (IQR 0.8). The median number of operations was 2.0 (IQR 4). For the primary outcome, there were a total of 0 (0/83) patients who required fasciotomy or developed early/late clinical sequelae of missed ACS. Six (6/83, 7.2%) patients developed deep infection, 18 patients (18/83, 21.7%) experienced nonischemic arterial injury, 5 patients (5/83, 6.0%) experienced nonunion, with 4 patients (4/83, 4.8%) experiencing flap failure. Diabetes was the only variable associated with deep infection (P = 0.025) and nonunion (P < 0.001). Patients with type IIIB open tibial shaft fractures treated with colloid resuscitation and a 2-stage orthoplastic protocol, which includes early "3-vessel view" exposure and debridement, do not appear to develop ACS. Furthermore, no sequelae of missed compartment syndrome was observed at final follow-up. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

One-stage reconstruction of bone defects with fibula perforator flap

At the current stage of reconstructive surgery development, perforator flaps have confidently taken a priority place when choosing a method for wound defects cover. However, wounds with significant volume defects of both soft tissues and the bone skeleton remain especially difficult challenges for the surgeon. The desired result of such defects repair could be a technique that allows surgeons to carry out an effective reconstruction in one step.The paper describes in detail the surgical and vascular anatomy, design, preoperative preparation and surgical technique for the mobilization of the free vascularized fibula perforator flap containing a fragment of the bone di-aphysis. Clinical examples of orthoplastic reconstruction in different locations are presented.The authors conclude that free fibula flap allows effective one-stage reconstruction of extensive wounds after trauma or oncological resections, including extensive defects of the skeleton, without significant loss of support function in the donor area. A chimera-style composite flap, which contains soft tissues and a fragment of the fibula, can already be called as a “workhorse" for orthoplastic reconstruction on the lower extremities and in the field of maxillofacial surgery.

Orthoplastic reconstruction in children: are the risk factors similar to those observed in adults?

Free flaps in the pediatric population are less common and when indicated the expectations to avoid amputation are high. The objective of this study is to describe indications and results of free flaps for limb reconstruction. Patients undergoing microsurgical free flaps in an orthopedic hospital were consecutively included in this cross-sectional study, from 2014 to 2020. Data regarding personal medical history, intraoperative microsurgical procedure and laboratory tests were collected. Patients under 18 years of age were included. Complications and free flap outcomes were observed during follow-up. This study included 23 free flaps in 23 patients with orthoplastic reconstruction. The free flap was performed as a reconstructive elevator concept. The most common indications were skin or bone defects caused by trauma (nine patients), tumor (six patients) and congenital pseudarthrosis of the tibia (four patients). The most indicated flap was a vascularized fibular flap in 10 patients, followed by an anterolateral thigh flap in 5 patients. Complications were observed in five patients. In total 93% of patients with inferior limb reconstruction walked at the final evaluation. Among risk factors studied, cases had a higher incidence of complications (P = 0.03) when only the superficial venous system was used. Free flaps in children are well-tolerated and indications are restricted to precise indications to provide alternatives to amputations and improve patient's function. We observed an increase in the incidence of complications when only superficial veins were used for free flap outflow in children.

Type III open complete articular fractures of the distal humerus: case series outcomes after orthoplastic reconstruction

Open complete articular injuries of this distal humerus are rare injuries which are challenging to manage. The study unit aims to present a small case series of Gustilo-Anderson type III open complete articular fractures which have undergone a single-stage definitive fixation and soft-tissue coverage, presenting their functional outcomes. Retrospective case series identifying all type IIIB AO 13-C3 distal humeral fractures from the unit trauma database. The primary outcome was the Oxford Elbow Score. Secondary outcomes included deep infection, nonunion, and reoperation. A total of six patients were identified, (four open type IIIA, 2 type IIIB). All patients underwent single-sitting definitive fixation and soft-tissue coverage. Mean range of motion arc was 90 degrees. The median Oxford Elbow Score was 35 (range 21-43), representative of mild to moderate arthritis. One patient (n= 1) developed deep infection at 24 months and required reoperation. All patients (n= 6) proceeded to union at the latest follow-up. We present a case report of a 59-years-old patient who sustained a type IIIB, AO 13-C3 distal humeral fracture who underwent single-sitting definitive fixation and flap coverage. This case series reports that positive functional outcomes representative of mild/moderate arthritis at short to midterm follow-up can be achieved after definitive fixation and soft-tissue coverage in a single sitting, including when the soft tissue is deficient. This is a rare injury which is under-reported in the literature.

Microsurgery and external fixation in orthoplastic reconstruction of tibial injuries.

"Orthoplastics" is a relatively new approach to lower limb reconstruction, where an integration of both plastic and orthopedic expertise is required, together with the availability of well-equipped facilities. Acute shortening and long-term frames for lengthening are generally considered alternatives to length preservation and soft tissue microsurgical reconstruction, but an integration of external fixation and reconstructive microsurgery is gaining an increasing role with refinements of joint approaches. Data on sixteen patients who underwent microsurgical lower limb reconstruction and external fixation with an orthoplastic approach, following acute or chronic tibial injury, were retrospectively reviewed. All patients presented a post traumatic soft tissue defect associated with a Gustilo III tibial fracture or a tibial septic pseudarthrosis. Data on type and timing of bone and soft tissue reconstruction, outcomes, complications and need for re-operation were extrapolated and compared to an historic group of patients treated with an orthopedic-based approach. In the orthoplastic group, soft tissues were reconstructed with an ALT flap in most cases; a muscle-sparing VL or ALT-VL chimeric flap was necessary in cases with a very extensive defect. In the orthopedic group, soft tissues were left to heal by second intention or patients were lately referred to plastic surgeons. Statistical comparison between the two groups has showed significant differences on the following data: time for soft tissue healing, time to bone union, number of reinterventions, post-operative deep infection rate, time to return to work. The orthoplastic approach to complex leg defects yields shorter treatment time and better functional results compared to the orthopedic-based approach. External fixation and microsurgical reconstruction are not necessarily alternative procedures but can integrate in an orthoplastic path to address at best both soft tissue and bone reconstruction.

The Effect of Age on Outcome in Excision of Chronic Osteomyelitis with Free Muscle Flap Reconstruction.

Introduction: Curative surgical treatment of chronic osteomyelitis often requires free tissue transfer if there is significant soft tissue compromise. We investigated whether age influenced outcomes of curative osteomyelitis excision in those patients requiring free muscle flap soft tissue reconstruction.Methods: We assessed ninety-five consecutive patients treated with excision of chronic osteomyelitis, skeletal stabilisation/reconstruction and free muscle transfer between 2006 and 2012. We compared outcomes of those aged ≥60 years (n=23) with those <60 years old (n=72).Results: Groups were similar with regard to Cierny and Mader anatomic type and physiological host classification. Length of procedure and length of hospital stay were similar for both groups. There was a greater proportion of ASA grade III patients in the older cohort. Infection recurrence occurred in one of the older cohort (4.3%) and in seven patients in the younger cohort (9.9%) at a mean follow-up of 42 months (range 11-131 months), this was not statistically significant (p=0.27874). There were five free flap losses (6.9%) in the younger group and none in the older group. A greater proportion of patients from the younger cohort required further unplanned surgery (28%) compared to the older group (4.3%), which was statistically significant (p=0.01174). Seven patients (7.4%) had serious medical complications - five of whom were in the younger cohort, including one mortality.Conclusions: Both the young and old can enjoy satisfactory outcomes from surgical resection of chronic osteomyelitis with simultaneous orthoplastic reconstruction including free tissue transfer. Age alone should not be a barrier to potentially curative surgical treatment.

Orthoplastic reconstruction of type IIIB open tibial fractures retaining debrided devitalized cortical segments

Type IIIB open tibial fractures are devastating high-energy injuries. At initial debridement, the surgeon will often be faced with large bone fragments with tenuous, if any, soft-tissue attachments. Conventionally these are discarded to avoid infection. We aimed to determine if orthoplastic reconstruction using mechanically relevant devitalized bone (ORDB) was associated with an increased infection rate in type IIIB open tibial shaft fractures. This was a consecutive cohort study of 113 patients, who had sustained type IIIB fractures of the tibia following blunt trauma, over a four-year period in a level 1 trauma centre. The median age was 44.3 years (interquartile range (IQR) 28.1 to 65.9) with a median follow-up of 1.7 years (IQR 1.2 to 2.1). There were 73 male patients and 40 female patients. The primary outcome measures were deep infection rate and number of operations. The secondary outcomes were nonunion and flap failure. In all, 44 patients had ORDB as part of their reconstruction, with the remaining 69 not requiring it. Eight out of 113 patients (7.1%) developed a deep infection (ORDB 1/44, non-ORDB 7/69). The median number of operations was two. A total of 16/242 complication-related reoperations were undertaken (6.6%), with 2/16 (12.5%) occurring in the ORDB group. In the setting of an effective orthoplastic approach to type IIIB open diaphyseal tibial fractures, using mechanically relevant debrided devitalized bone fragments in the definitive reconstruction appears to be safe.

Pain after ortho-plastic reconstruction of lower limb injuries: A snapshot study

IntroductionThe incidence of pain after flap reconstruction of complex lower limb injury is poorly reported in the literature, and yet represents a significant source of morbidity in these patients. In our centre (Southmead Hospital, Bristol, England) patients who have had flap reconstruction for complex lower limb injury are followed up at a joint ortho-plastics lower limb clinic run weekly. The aim of this study was to report the incidence of pain in such patients at follow-up in the specialist clinic. The impact of the experience of pain upon the quality of life, and the efficacy of analgesia was assessed these cases. Patients and methodsThis was a cross sectional snapshot study of a cohort of complex lower limb patients attending our lower limb ortho-plastics outpatient clinic between the dates of: 17/5/16 and 28/6/16. Any patient attending clinic with previous flap reconstruction for lower limb injury was asked to complete the BPI (Brief Pain Index) questionnaire, and details regarding their injury and surgery were collected. ResultsThere was a 100% response rate, with 33 patients completing the questionnaire. 28 out of the 33 patients (85%) reported ongoing pain. There was no significant relationship between time post operatively and average pain scores (Spearman’s Rank R = 0.077), nor was there significant difference by age or gender. Over 25% of the patients with pain were not taking analgesia, however those using simple analgesia (paracetamol, NSAIDS) derived on average over 70% pain relief. ConclusionsPain in a common complication following flap reconstruction for complex lower limb injury reported in 85% of our cohort. This pain does not seem to be correlated with time, gender or age, and responds well to simple analgesia in most cases. This emphasises the importance of asking about pain at follow up, and taking simple measures to improve pain outcomes.

Single-stage orthoplastic reconstruction of Gustilo–Anderson Grade III open tibial fractures greatly reduces infection rates

BackgroundGrade III open fractures of the tibia represent a serious injury. It is recognised that combined management of these cases by experienced orthopaedic and plastic surgeons improves outcomes. Previous studies have not considered the timing of definitive soft tissue cover in relation to the definitive orthopaedic management. This paper reviews the outcomes in patients treated in an orthoplastic unit where the emphasis was on undertaking the definitive orthopaedic and plastic surgical procedures in a single stage, following initial debridement and temporary stabilisation as necessary. MethodsWe reviewed medical notes of 73 consecutive patients with 74 Grade III open tibia fractures (minimum 1 year follow up), to compare deep infection rates in patients who had (a) a single-stage definitive fixation and soft tissue coverage vs. those who had separate operations, and (b) those who had definitive treatment completed in <72h vs. >72h. Results(a) Combined Single-stage Orthoplastic Fixation and Coverage: 48 fractures were managed with definitive orthopaedic fixation and plastic surgical coverage performed at the same time, whilst 26 had these performed at separate stages. Of those subjects that had definitive fixation and coverage in one procedure 2 (4.2%) developed deep infections, compared with 9 (34.6%) deep infections (p<0.001) in those who underwent definitive fixation and coverage at separate operations. (b) Timing of surgery: Of the fractures that had definitive fixation and coverage completed within 72h of injury, 5 (20%) developed deep infections, compared with 6 (12.2%) deep infections (p=0.492) in those whose definitive fixation/coverage was completed at later than 72h. ConclusionJoint orthoplastic operating lists facilitate simultaneous definitive fixation and cover that greatly reduces infection rates. Based on our experience presented in this paper, we believe that emphasis should be placed on timely transfer to a specialist centre, aiming for a single-stage combined orthoplastic procedure to achieve definitive fixation and soft tissue coverage and optimal outcomes.

Orthoplastic Reconstruction after Lower Limb Major Amputation

Orthoplastic Reconstruction after Lower Limb Major Amputation

Funktionelle Langzeitergebnisse nach Sarkomresektionen

Multimodal treatment of malignant tumors of the musculoskeletal system with R0 in sano resection plays a key role in prevention of local recurrence in soft tissue and bone sarcoma. In cases of unavoidable neuromuscular or osseous defects, current plastic and orthoplastic reconstruction techniques avoid limb amputation in the majority of patients. Clinical long-term results demonstrate that large resection defects do not necessarily result in impaired limb function if multidisciplinary procedures are integrated. In oncologically necessary major limb amputation, segmental resection and replantation of distal limb parts should be considered which provide end-bearing long stump formation. The functional conditions of long-term surviving elderly patients should be integrated into surgical decision-making and rehabilitation efforts.

Images in vascular medicine

Internal carotid artery (ICA) dissection is a rare complication of major trauma,1,2 typically presenting soon after injury with symptoms of major stroke.3 ICA dissections also occur following minor trauma, and may present with more trivial symptoms, typically headache associated with focal neurological signs. The classic triad of Horner’s syndrome and pain, followed by cerebral or retinal ischaemic symptoms, is present in only about 20% of patients with ICA dissection.4 In cases of major trauma, disruption of the ICA is often present on initial trauma CT scanning, or becomes apparent early following the development of symptoms suggestive of cerebral ischaemia or infarction reflecting disruption of the ICA. It appears to be much less common for ICA dissection to present with focal neurological signs late following major trauma, as in the case outlined below. A previously well 36-year-old motorcyclist was thrown from his bike into a passing car, sustaining multiple leftsided long bone and pelvic fractures which required extensive ortho-plastic reconstruction and a prolonged stay on the intensive care unit. Two left neck lacerations were explored surgically at initial presentation; the carotid sheath was intact. As the patient recovered he reported some visual loss in the left eye.
