[Base-of-thumb osteoarthritis: aspects to be considered with the indication of trapeziectomy and CMC I prosthesis]. / Die Daumensattelgelenksarthrose ­ Aspekte zur Indikationsstellung von Resektionsarthroplastik und Daumensattelgelenksprothese.

Base-of-thumb osteoarthritis is the most frequent osteoarthritis of the hand requiring surgical treatment, although conservative treatment options should be exhausted before surgery. If the wear process progresses with continuing pain-related loss of thumb function, thus leading to a loss of function of the whole hand, surgical treatment is indicated. In 1947, Gervis published results after trapeziectomy and heralded the development of a multitude of different surgical procedures. The long time needed for rehabilitation is a major problem of trapeziectomy with or without tendon interposition and/or suspension. After the implementation of the first CMC I prosthesis by De la Caffiniere 50 years ago, a rapid development took place, leading to the current modular bipolar implants. Especially in the German-speaking world, there is still some scepticism regarding these prostheses, which is why this review aims to illuminate both surgical procedures with a special focus placed on the aspects of indication.

Trapeziectomy versus Maïa Prosthesis in Trapeziometacarpal Osteoarthritis.

Background Osteoarthritis at the base of the thumb is the most frequent osteoarthritis of the hand. Trapeziectomy in a broad variety of surgical methods have been proposed to achieve pain reduction and improvement of thumb function. A well-known disadvantage is the long recovery time. Arthroplasty of the thumb carpometacarpal joint is a competing new method for this indication with different revision and complication rates reported. Purposes The aim of this study is to assess whether there are significant differences in outcome during the first 12 months and time return to work after either, implant of a Maïa joint prosthesis, or trapeziectomy with tendon interposition after Weilby. Patients and Methods This clinical follow-up study compares the efficacy of total basal joint replacement using the Maïa prosthesis with tendon interposition arthroplasty in 59 thumbs. Clinical, functional, and radiological results at preoperative, 3-, 6-, and 12-month postoperative are presented. Results We found a significant shorter return to work in the prosthesis group with 4.5 compared with 8.6 weeks. In addition to a significant difference in pain reduction with a better Mayo wrist score in the Maïa group after 3 months. The scores are closer after 6 months and nearly match after 12 months. Measurement of the pinch grip showed a parallel course. A radiological loosening of the cup in two patients was detected after 12 months. Conclusion Implantation of Maïa prosthesis enables a significant shorter recovery but is associated with the risk of loosening and higher costs. Level of Evidence Level IV, case-control study.

Avoiding screw overlength using dorsal horizon view in palmar plate osteosynthesis of distal radius fractures: a prospective randomized trial.

INTRODUCTION: Distal radius fractures are the most commonly reported fractures in adults. Treatment has changed in recent years to open reduction and palmar plate fixation. Penetration of the dorsal screw, however, is a well-known complication. Intraoperative anteroposterior and lateral radiographs lack the exact assessment of dorsal screw length and intraoperative measurement is therefore very likely to be inaccurate in a comminuted dorsal radial cortex. Secondary extensor tendon ruptures are reported in up to 6% following palmar plate fixation of distal radius fracture. MATERIALS AND METHODS: A prospective randomized trial was performed to assess the value of the dorsal horizon view. The hypothesis was that the traditional anteroposterior and lateral fluoroscopic views aided by an axial view of the dorsal part of the radius, named dorsal horizon view, could prevent dorsal screw penetration. A total of 40 patients, 6 male and 34 female, were included in the study. Standardized anteroposterior and lateral radiographs were performed intraoperatively in 18 patients (standard group = control group). In 22 patients, intraoperative axial fluoroscopic views (dorsal horizon view) were added to anteroposterior and lateral images (horizon group). Numbers of intraoperative screw changes due to the two different radiological examinations were analyzed as well as exact postoperative CT guided measurement of screw length. RESULTS: The total numbers of intraoperative screw changes were significantly higher in the horizon group. Forty-two screws were changed in 15 patients in the horizon group while only 8 screws were changed in 3 patients in the standard group. Postoperative computed tomography scans showed significantly lower total numbers of perforating screws in the horizon group with 11 screws in 22 patients compared to 20 screws in 18 patients in the standard group (p = 0.02). CONCLUSIONS: Based on the results of this study, the dorsal horizon view improves the assessment of the correct screw length and should routinely be used in palmar plate osteosynthesis of distal radius fractures. Since screw protrusion cannot be absolutely ruled out using the dorsal horizon view, monocortical drilling or screw downsizing is still mandatory. TRIAL REGISTRATION: This clinical trial was not registered because it was a clinical examination without any experimental techniques.

Lateral Femoral Trochlea Osteochondral Flap Reconstruction of Proximal Pole Scaphoid Nonunions.

PURPOSE: The medial femoral trochlea flap has been described as a method of scaphoid proximal pole nonunion reconstruction when the proximal pole is deemed nonsalvageable. The lateral femoral trochlea (LFT) is an alternative donor site providing a comparable vascularized convex osteochondral flap. We describe the technique and outcomes of our first 17 cases of LFT flap reconstruction of the proximal scaphoid pole with a minimum follow-up of 14 months. METHODS: Seventeen of the first 24 patients who underwent LFT scaphoid reconstruction at 3 institutions were able to be contacted for clinical follow-up and chart reviews. We recorded patient age and sex, duration of nonunion, number of previous surgical procedures, details of surgical technique, achievement of osseous union, complications, additional postoperative procedures, preoperative and postoperative pain, and range of motion. Preoperative and postoperative scapholunate and radiolunate angles were analyzed on x-rays and achievement of osseous union on computerized tomography scans. RESULTS: The average age of patients included was 35 years (range, 16-55 years). Follow-up data were recorded at an average of 33 months (range, 14-62 months). Ten patients had previous procedures (average, 1; range, 0-2). Median duration from trauma to LFT was 3.4 years (range, 8 months-12 years) among patients who had a recognized date of injury. Osseous healing was achieved in 16 of 17 patients and confirmed by computerized tomograpy scan. Twelve patients reported complete pain relief, while 5 reported partial pain relief. Final postoperative range of motion was 59°extension (range, 30°-85°) and 50° flexion (range, 10°-80°), which was comparable to preoperative values. Preoperative (59°) and postoperative (55°) scapholunate angles were similar to normal wrists. CONCLUSION: Vascularized LFT flaps provide an alternative donor site for vascularized osteochondral reconstruction of proximal pole scaphoid nonunion. Rate of union, range of motion, and pain relief are similar to reported results with medial femoral trochlea flap reconstruction. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Vascularized osteochondral free flaps from the femoral trochlea as versatile procedure for reconstruction of osteochondral lesions of the talus.

BACKGROUND: Osteochondral lesions of the talus (OLT) are defects affecting the articular cartilage as well as the subchondral bone, on the lateral shoulder possibly associated with trauma. This study presents the results of reconstructing OLT using vascularized osteochondral flaps from the femoral trochlea. METHODS: We treated 19 patients with osteochondral talar shoulder defects, using osteochondral flaps from the medial (MFT) or lateral (LFT) femoral trochlea. Functional outcome was evaluated by clinical investigation, visual analogue scale (VAS, 0-10), American Orthopaedic Foot and Ankle Society-Ankle and Hindfoot Scale (AOFAS, 0-100) and The Foot and Ankle Disability Index (FADI, 0-104). Radiographic postoperative follow-up was done by anterior-posterior and lateral X-rays and union of the transferred osteochondral flaps was documented by CT scans. RESULTS: The osteochondral flaps fused in all of the 19 cases. After a median follow-up of 45.5 months, the patients showed an average FADI of 94.9 and AOFAS-Ankle and Hindfoot Scale of 91.2. All of them were walking free and normal. Subjective median satisfaction was 1.3 in a scale from 1 to 5. CONCLUSION: Vascularized transfer of osteochondral flaps from the femoral trochlea is a reliable treatment option for symptomatic OLT of the medial and lateral talar edge. LEVEL OF CLINICAL EVIDENCE: Therapeutic IV.

The free vascularized lateral femoral trochlea osteochondral graft: a reliable alternative for Stage III Kienböck's disease.

Lunate reconstruction using a lateral femoral trochlea osteochondral graft was carried out in 27 patients with Stage III Kienböck's disease from 2012 to 2019. Twenty-three of these patients could be followed-up in this retrospective study. Ten were women and 13 men. Nine were Lichtman Stage IIIA, seven Stage IIIB and seven Stage IIIC. The mean follow-up was 39 months (range 12-86). Bony consolidation was found in 18 of the 23 patients, with no graft loss. The mean Disabilities of the Arm, Shoulder and Hand score (DASH score) was 11 and the Modified Mayo Wrist Score was 83. There were only two radiological deteriorations, with the same or improved Lichtman classifications in the other patients and a significant reduction in pain. Postoperative extension of the wrist (52°) and flexion (48°) were comparable with preoperative values and, respectively, 81% and 72% of the contralateral side. Grip strength and pinch grip were 32 kg and 12 kg, 88% and 94% of the other hand, respectively, and an insignificant increase compared with the preoperative values. The vascularized lateral femoral trochlea osteochondral graft yields good short- and mid-term results in Grade III Kienböck's disease.Level of evidence: IV.

[Extracorporeal Shockwave Therapy for the treatment of scaphoid delayed union and nonunion: a retrospective analysis examining the rate of consolidation and further outcome variables]. / Hochenergetische extrakorporale Stoßwellentherapie bei verzögerter Heilung von Kahnbeinfrakturen und Pseudarthrosen: eine retrospektive Analyse der Konsolidierungsrate und therapieentscheidungsrelevanter Faktoren.

BACKGROUND: Operative procedures are considered gold standard in the treatment of scaphoid nonunion, albeit their considerable complexity and the risk of intraoperative complications. High energy extracorporeal shockwave therapy (ESWT) offers a non-invasive treatment option for scaphoid nonunion. The aim of this study was to explore the rate of bony consolidation and further outcome variables in patients with delayed union of scaphoid fractures and scaphoid nonunion treated with ESWT. PATIENTS AND METHODS: Due to delayed union (21) or nonunion (21) of a scaphoid fracture 42 patients (37 men, and 5 women) with an average age of 48,3 (15-66) years underwent ESWT followed by immobilization in a forearm cast including the proximal phalanx of the thumb for 6 to 8 weeks. In 13 patients the fracture was initially treated, 8 with immobilization, 5 with screw fixation. In 5 of the 29 patients without an initially treatment, the fracture resp. nonunion was secondarily treated with screw fixation (2) or a medial femur condyle (3) but failed to heal. 10 to 12 weeks after the ESWT bony healing was controlled with computed scanning in the long axis of the scaphoid. If 50 % of diameter of the scaphoid showed trabecula bony healing was considered. Factors with potential influence on bony healing (site of the fracture/nonunion, scapholunate angle, patient´s age, Body Mass Index, smoking and alcohol consume) were analyzed. In addition, 34 patients underwent a clinical follow-up examination including DASH and Mayo Wrist Score, pain analyzes (VAS). RESULTS: Seventy-one per cent of patients showed scaphoid fracture consolidation using ESWT. In 7 out of 8 patients with conservative treatment and in 4 out of 5 patients with screw fixation of the initial fracture bony healing was achieved. From the 5 patients with secondary surgical treatment of the scaphoid only 1 patient, treated with a medial femur condyle, failed to heal the scaphoid. 15 out of the 24 initially non-treated scaphoid fractures healed. The time between ESWT and the documented bony healing averaged 8.4 months (256 days). Neither fracture site, nor the scapholunate angle, alcohol and tobacco use, as well as biometric factors, such as age and BMI had influence on the success rate of the ESWT. Side effects of the ESWT were limited to local skin irritations and petechial bleedings. CONCLUSION: ESWT has a positive effect regarding bony healing of scaphoid fracture with delayed fracture healing and nonunion with a success rate of 71 %. The complication rate is low, and the clinical results regarding wrist motion and pain are satisfying. Further investigations are necessary to evaluate the input of fracture/nonunion characteristics like the morphological appearance on bony healing.

Knee Donor Site Morbidity Following Harvest of Medial Femoral Trochlea Osteochondral Flaps for Carpal Reconstruction.

PURPOSE: This study examines donor site morbidity associated with the medial femoral trochlea (MFT) when used as a donor site for vascularized osteochondral flaps for reconstruction of challenging carpal defects such as proximal pole scaphoid nonunion and advanced Kienböck disease. METHODS: The retrospective study population included all patients who had undergone MFT flap harvest for scaphoid or lunate reconstruction. Chart review, patient questionnaires, and validated knee function assessment tools were used: International Knee Documentation Committee Subjective Knee Form scores ranged from 0 (maximal disability) to 100 (no disability). Western Ontario and McMaster Universities osteoarthritis index scores ranged from 0% (no disability) to 100% (maximal disability). Magnetic resonance imaging and radiographs were obtained on the donor knee on the majority of patients. RESULTS: Questionnaire response rate was 79% (45 of 57 patients). Average patient age was 35 ± 11 years (range, 19-70 years). Average postoperative follow-up was 27 ± 17 months (range, 9-108 months). The indication for MFT flap reconstruction was scaphoid nonunion in 30 patients and Kienböck disease in 15 patients. All 45 patients had a stable knee on examination. Magnetic resonance and radiographic imaging obtained on 35 patients exhibited no pathological changes. Average duration of postoperative pain was 56 ± 59 days (range, 0-360 days); average duration until patients reported the knee returning to normal was 90 ± 60 days (range, 14-360 days). Forty-three of 44 patients would have the same surgery again if needed; overall satisfaction with the surgery was rated as 5 ± 1 (range, 2-5) on a scale from 0 (no satisfaction) to 5 (maximal satisfaction). Average International Knee Documentation Committee score was 96 ± 9 (range, 56.3-100) and the average Western Ontario and McMaster Universities score was 6% ± 16% (range, 0%-68%). CONCLUSIONS: Medial femoral trochlea osteochondral flap harvest results in minimal donor site morbidity in the majority of patients. Symptoms are time limited. Intermediate-term follow-up demonstrates excellent results in subjective outcome measures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Vascularized medial femoral trochlea osteochondral flap reconstruction of advanced Kienböck disease.

PURPOSE: To describe the operative technique and report the results of 16 consecutive cases of arthroplasty for advanced Kienböck disease using a vascularized osteochondral graft from the medial femoral trochlea (MFT) with a minimum 12-month follow-up. METHODS: Chart reviews of 16 cases of osteochondral MFT flap transfers for lunate reconstruction were performed in 2 institutions. Mean patient age was 35 years (range, 19-51 y). Preoperative Lichtman staging was 2 in 7 patients, 3a in 8 patients, and 3b in 1. Five of 16 patients had undergone a previous procedure for Kienböck disease (3 radial shortening osteotomies, 1 wrist denervation, and 1 distal radius vascularized bone grafting). Ulnar variance recorded at the time of the MFT reconstruction was negative in 8 patients, positive in 6 patients, and neutral in 2 patients. Follow-up data were recorded at a minimum of 12 months (average, 19 mo). Radiographic parameters recorded included preoperative ulnar variance, preoperative and final follow-up radioscaphoid angle, lunate height, lunate diameter, and the Stahl index and Lichtman stage. RESULTS: Healing was confirmed in 15 of 16 reconstructed lunates. Lichtman staging remained unchanged in 10 patients, improved in 4 patients from grade 3a and 3b to 2, and worsened in 2 patients from grade 3a to 3b. All but 1 patient experienced improvement in wrist pain (12/16 complete relief; 3/16 incomplete relief). Wrist motion at follow-up averaged 50° extension and 38° flexion, similar to preoperative measurements. Grip strength at follow-up was 85% of the contralateral side. CONCLUSIONS: Osteochondral vascularized MFT flaps provided a reliable means of lunate reconstruction in advanced Kienböck disease. This flap allowed resection of the proximal portion of the collapsed lunate and reconstruction with an anatomically analogous convex segment of vascularized cartilage-bearing bone. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Vascularized medial femoral trochlea osteocartilaginous flap reconstruction of proximal pole scaphoid nonunions.

PURPOSE: The descending geniculate artery's branching pattern includes periosteal vessels supplying the cartilage-bearing trochlea of the medial patellofemoral joint. Previous cadaveric studies described anatomic similarities between the greater curvature of the proximal scaphoid and the convex surface of the medial femoral trochlea (MFT). We describe the technique and report our first 16 consecutive cases of vascularized osteocartilaginous arthroplasty for chronic scaphoid proximal pole nonunions using the MFT, with a minimum of 6 months of follow-up. METHODS: Chart reviews of 16 consecutive cases of osteocartilaginous MFT flap transfers for scaphoid reconstruction were performed at 2 institutions. Follow-up data were recorded at a minimum of 6 months, with an average of 14 months (range, 6-72 mo). Patient age and sex, duration of nonunion, number of previous surgical procedures, surgical technique, achievement of osseous union, preoperative and postoperative scapholunate angles, preoperative and postoperative range of motion, and pain relief were recorded. RESULTS: Computed tomography imaging confirmed healing in 15 of 16 reconstructed scaphoids. Mean patient age was 30 years (range, 18-47 y). The average number of previous surgical procedures was 1 (range, 0-3). All patients experienced some wrist pain improvement (12/16 complete relief, 4/16 incomplete relief). Wrist range of motion at follow-up averaged 46° extension (range, 28° to 80°) and 44° flexion (range, 10° to 80°), which was similar to preoperative measurements (average 46° extension and 43° flexion). Scapholunate relationship remained unchanged with average scapholunate angles of 52° before surgery and 49° after surgery. CONCLUSIONS: Osteochondral vascularized MFT flaps provide a reliable means of achieving resolution of difficult proximal pole scaphoid nonunions. These flaps allow resection of the proximal portion of the unhealed scaphoid and reconstruction with an anatomically analogous convex segment of cartilage-bearing bone. This technique provides the advantages of vascularized bone and ease of fixation. Early follow-up demonstrates a high rate of union with acceptable motion and pain relief. CLINICAL RELEVANCE: Early follow-up suggests that the vascularized MFT osteocartilaginous flap is a valuable tool for treating challenging proximal pole scaphoid nonunions.

Local fasciocutaneous infragluteal (FCI) flap for vulvar and vaginal reconstruction: a new technique in cancer surgery.

INTRODUCTION: Soft tissue reconstruction after vulvar, vaginal, or anal cancer resection poses a formidable task for reconstructive surgeons because of the functional, locational, and cosmetic importance of this region. Although numerous flaps have been designed for vulvar reconstruction, each has its disadvantages. METHODS: The authors introduce the local fasciocutaneous infragluteal (FCI) flap for vulvar and vaginal reconstruction after tumor resection, vaginal scar obliteration, and vulvar ulceration in 15 patients operated on between 1999 and 2007. The FCI flap is supplied by the cutaneous branch of the descending branch of the inferior gluteal artery. The sensory supply of this flap comes from side branches of the posterior cutaneous nerve of the thigh. A total of 17 flaps were performed in 15 patients. RESULTS: Except for one, all flaps survived. One flap necrosis occurred because of false postoperative position with compression and tension to the vascular pedicle. In the remaining patients, we found one local cancer recurrence with necessity of a second flap from the contralateral side. The patients report satisfaction with reconstruction, without one having pain at donor site and recurrent vaginal ulceration. CONCLUSIONS: This article discusses the expanding indications of this versatile flap and the operative technique of the local FCI flap for reconstruction of vulvar and partial vaginal defects. It can be raised in different volume and dimension out of possible irradiated area with an inconspicuous scar.

Thromboelastometric (ROTEM) findings in patients suffering from isolated severe traumatic brain injury.

Severe traumatic brain injury (sTBI) is often accompanied by coagulopathy and an increased risk of bleeding. To identify and successfully treat bleeding disorders associated with sTBI, rapid assessment of coagulation status is crucial. This retrospective study was designed to assess the potential role of whole-blood thromboelastometry (ROTEM(®), Tem International, Munich, Germany) in patients with isolated sTBI (abbreviated injury scale [AIS](head) ≥3 and AIS(extracranial) <3). Blood samples were obtained immediately following admission to the emergency room of the Trauma Centre Salzburg in Austria. ROTEM analysis (EXTEM, INTEM, and FIBTEM tests) and standard laboratory coagulation tests (prothrombin time index [PTI, percentage of normal prothrombin time], activated partial thromboplastin time [aPTT], fibrinogen concentration, and platelet count) were compared between survivors and non-survivors. Out of 88 patients with sTBI enrolled in the study, 66 survived and 22 died. PTI, fibrinogen, and platelet count were significantly higher in survivors (p<0.005). Accordingly, aPTT was shorter in this group (p<0.0001). ROTEM analysis revealed shorter clotting times in extrinsically activated thromboelastometric test (EXTEM) and intrinsically activated thromboelastometric test (INTEM) (p<0.001), shorter clot formation times in EXTEM and INTEM (p<0.0001), and higher maximum clot firmness in EXTEM, INTEM, and FIBTEM (p<0.01) in survivors compared with non-survivors. Logistic regression analysis revealed extrinsically activated thromboelastometric test with cytochalasin D (FIBTEM) MCF and aPTT to have the best predictive value for mortality. According to the degree of coagulopathy, non-survivors received more RBC (p=0.016), fibrinogen concentrate (p=0.01), and prothrombin complex concentrate (p<0.001) within 24 h of arrival in the emergency room. ROTEM testing appeared to offer an early signal of severe life-threatening sTBI. Further studies are warranted to confirm these results and to investigate the role of ROTEM in guiding coagulation therapy.

Treatment of segmental bone and soft-tissue defects of the forearm with the free osteocutaneous lateral arm flap.

BACKGROUND: Complex defects of the forearm often require microvascular reconstruction with osteocutaneous free flaps to salvage the limb. In this review, we report our experience with the use of the free osteocutaneous lateral arm flap to reconstruct such defects in four patients. METHODS: Three male patients with osseous defects of the ulna and one defect of the radius with associated soft-tissue defects were treated with a free osteocutaneous lateral arm flap between 2004 and 2007. The indications for the procedure included posttraumatic osteitis (3) and bone with soft-tissue defects after trauma (1). We evaluated the patients with respect to postoperative results by evaluating the range of motion, pain, strength, and score on the disabilities of the arm, shoulder, and hand questionnaire. Donor-site morbidity was also documented. RESULTS: The average length of segmental bone defects was 5.75 cm. The average dimension of the skin paddle was 99.5 cm. The average duration of follow-up was 43.3 months. All bone flaps healed without nonunion; the fasciocutaneous flaps healed without complications. No problems related to microanastomoses were found. Functional results were very satisfactory; disabilities of the arm, shoulder, and hand questionnaire scores showed a median of 5.8 (0-10.8). All patients had returned to their preinjury occupations. CONCLUSION: This analysis demonstrates that the free osteocutaneous lateral arm flap is an effective treatment for combined segmental osseous and soft-tissue defects of the forearm that are caused by osteitis and trauma.

Autologous breast augmentation with the deepithelialized fasciocutaneous infragluteal free flap: a 10-year experience.

INTRODUCTION: Breast augmentation with silicone implants is frequently performed, a daily procedure in plastic surgery. Nevertheless, there are well-known risks of capsular formation and contraction leading to pain, displacement, and rupture after breast augmentation. Thus, the frequency of augmentation with autologous tissue is increasing. Most frequently used are the transverse rectus abdominis muscle flap, the deep inferior epigastric artery perforator flap, and the gracilis free flap, but in some cases, these flaps are not the first choice. Therefore, we present our experience with the free fasciocutaneous infragluteal (FCI) flap. METHODS: The FCI flap is based on a constant end artery of the inferior gluteal artery and has frequently been used for various indications at our department for many years. Since 1998, 17 patients suffering from breast hypoplasia, congenital breast asymmetry, or consecutive capsular fibrosis were treated with 25 FCI flaps. RESULTS: In this series, no complete or partial flap loss was clinically detected. The only complaint was a discomfort at the donor site in the early postoperative period. As revealed by a final questionnaire, all patients were satisfied with the result. CONCLUSION: Our results suggest that the FCI flap should be considered as a worthy alternative for autologous breast augmentation, especially in thin patients suffering from breast hypoplasia, congenital asymmetry, or consecutive capsular formations.

Perineal reconstruction after rectal and anal disease using the local fascio-cutaneous-infragluteal flap: A new and reliable technique.

BACKGROUND: Significant morbidity can result from perineal wounds, particularly if the tissue has been partially devitalized after radiotherapy and extensive resection for cancer or chronic inflammation which may occur in Crohn's disease. Many different types of flaps have been used to improve healing of perineal tissue defects. The purpose of this study was to evaluate the morbidity and outcomes of reconstruction using the local fasciocutaneous infragluteal (FCI) flap. METHODS: Fourteen consecutive patients undergoing local FCI flap reconstruction for perineal wounds and defects were included in the study. In 5 female patients, the defect included the dorsal wall of the vagina, which was reconstructed in 1 step. Ten patients underwent operations for anal or low rectal cancer, 3 suffered from Crohn's disease and extensive local fistula formation, and 1 young girl presented with a defect after resection of a perineal synovial sarcoma. Eleven of these patients underwent preoperative chemotherapy and either pre- or intra-operative radiotherapy. RESULTS: Complete healing of perineal wounds occurred in 13 of the 14 patients. There were 4 flap-related complications, including 3 patients with delayed wound healing and wound dehiscence and 1 patient with partial flap necrosis. The last patient required a second local flap for wound closure. In 2 patients, a second FCI flap was necessary because of a second tumor and a local tumor recurrence. Ambulation and normal mobility were possible after the flap procedure in all patients without restriction of activity. Four patients died during the follow-up period (median, 42.5 months) from tumor metastasis. CONCLUSION: Local FCI flap for reconstruction of large perineal defects achieves good wound healing with only moderate morbidity in most patients after extensive resection owing to cancer or Crohn's disease.

Pectus excavatum and free fasciocutaneous infragluteal flap: a new technique for the correction of congenital asymptomatic chest wall deformities in adults.

BACKGROUND: Pectus excavatum is typically a cosmetic congenital chest wall deformity. In most cases, it does not affect heart and lung function; therefore, because of their high rate of complications, extensive procedures need not be performed. Various alternative techniques (e.g., reconstruction with silicone prosthesis or the transverse rectus abdominis musculocutaneous flap) were introduced in asymptomatic pectus excavatum. All of these methods have their advantages but also limitations. Thus, the authors used a free fasciocutaneous infragluteal flap for reconstruction of asymptomatic pectus excavatum in selected patients. METHODS: Between 2001 and 2007, six patients suffering from asymptomatic pectus excavatum underwent correction with the free fasciocutaneous infragluteal flap. The fasciocutaneous infragluteal flap is based on a constant end artery of the inferior gluteal artery. After raising of the flap and wound closure in the buttock region, the flap was adjusted to the defect using a small skin incision in the inframammary fold, and the vessels were anastomosed. RESULTS: There were no flap losses and no major complications. One patient suffered from a sensory change at the posterior thigh in the early postoperative period that resolved completely within 2 weeks. In four cases, flap shaping or liposuction was performed to improve the aesthetic result. In the authors' final evaluation, all patients were very satisfied with the result and would undergo the procedure again. CONCLUSIONS: The authors have demonstrated for the first time the reconstruction of asymptomatic pectus excavatum with the free fasciocutaneous infragluteal flap. It is the authors' opinion that, in selected patients, this flap offers an excellent alternative to established techniques for this problem.

Bone, tendon, and soft tissue reconstruction in one stage with the composite tensor fascia lata flap.

A 46-year-old patient sustained a dia-infracondylar tibial fracture after a ski accident. Open reduction and internal fixation (ORIF) was carried out. After an initially uneventful postoperative course the patient was readmitted because of local and systemic infection signs. Radical surgical debridement was carried out following by Vacuum-Assisted Closure (VAC) therapy. The resulting defect consisted of bone defect of the tibia tuberosity, and complete loss of the patellar tendon and the overlying soft tissue. Reconstruction was carried out with a combined tensor fascia lata (TFL) flap including the TFL muscle with the ilio-tibial tract, vascularized part of the iliac crest and the overlying soft tissue. Bone healing took place without signs of osteomyelitis recurrence, and full weight bearing was possible 4 months after reconstruction. Successful reconstruction of the patellar tendon using the ilio-tibial tract, enables the patient full active knee joint motion. The soft tissue coverage shows stable conditions. The donor site showed inconspicuous healing without pain and normal range of motion of the hip joint. So this composite TFL flap is an interesting flap not only for defects following trauma, but also for combined defects following extensive infections after knee implants.

Reconstruction of soft tissue defects overlying the Achilles tendon using the super extended abductor hallucis muscle flap.

BACKGROUND: Soft tissue defects overlying the Achilles tendon often occur after traumatic ruptures of the Achilles tendon or because of pressure ulcers in patients suffering from circulatory problems. Ideally, reconstruction should be achieved in as few stages as possible. Currently, there are different methods used to treat these defects. Here, we examined whether reconstruction of this region could benefit from the super extended abductor hallucis muscle flap. METHODS: In 12 cadaver feet, the vascular supply and mobilization radius of the abductor hallucis muscle were studied to clarify the possible clinical utilization of this flap. A technique for Achilles defect reconstruction using this flap, along with the functional and cosmetic results in six patients are presented. RESULTS: Our anatomic findings agree with those available in the literature and the adaptation in pedicle preparation allowed an increase in rotation of the flap for successful coverage of defects overlying the Achilles tendon. Using the super extended abductor hallucis muscle flap, the functionality and the anatomic shape were successfully reconstructed. Six weeks after surgery all patients were fully mobile, unless they suffered from Achilles tendon ruptures then they were mobile after 12 weeks. CONCLUSIONS: The super extended abductor hallucis muscle flap might represent an alternative to established methods because of ease of handling and a shorter anesthesia compared with a free flap procedure.

Breast reconstruction with the fasciocutaneous infragluteal free flap (FCI).

Thin patients who will not accept breast reconstruction with foreign material may not have enough tissue associated with the TRAM or latissimus muscle to achieve an acceptable reconstruction. We feel the next choice is tissue from the infragluteal region raised and moved as a free fasciocutaneous flap (FCI) based on the descending branch of the inferior gluteal artery. This (FCI) has not been described for this to our knowledge. Thirty-five FCI flaps were done for 28 patients between 1998 and 2005 for autologous breast reconstruction, as well as simultaneous augmentation of the contralateral breast in 4 of these patients. There was no flap loss. Complications include seroma, scar pain, and fat necrosis and are reported and discussed. We suggest that the FCI flap be considered as a worthy alternative for autologous breast reconstruction in thin patients.
