Gastrocnemius muscle flap

Purpose: Congenital pseudarthrosis of the tibia is a rare disease that is particularly difficult to treat; the most difficult complications include nonunion of the tibia, refracture, and failed surgery. This study aimed to evaluate the efficiency of transposing gastrocnemius flaps for the treatment of congenital pseudarthrosis of the tibia. Methods: Nine patients (aged 6.2 ± 3.6 years) diagnosed with congenital pseudarthrosis of the tibia in our hospital between March 2013 and March 2018 were enrolled...

Soft tissue defects with exposed tendon, bones, and joints around the knee are difficult and challenging to treat because of its location over a joint, requires a stable cover that is supple and stretchable. For any knee defects, the gastrocnemius muscle flap is the first choice for the reconstruction, although it causes less functional deficit; however, because of its less reach, it is difficult to cover the defect in the superolateral aspect of knee joint and anterior to the tibial tuberosity with the other disadvantage being the bulkiness...

INTRODUCTION AND IMPORTANCE: The incidence of postoperative infection after ACL reconstruction is reported to be 0.3 to 1.7%. Early debridement and complete removal of the artificial implant have been reported to be very important for complete recovery from postoperative infection after ACL reconstruction. Extra-articular infection of tibial tunnel post ACL reconstruction is a rare case and only a few cases are reported in the literature. The treatment for this lesion is not defined. CASE PRESENTATION: We report a 36-year-old case of recurrent infection at the tibial bone tunnel after ACL reconstruction...

OBJECTIVE: Restoration of the extensor apparatus in the case of advanced tendon defects as part of revision total knee arthroplasty (TKA). Reconstruction and augmentation using vascularized gastrocnemius muscle and tendon. INDICATIONS: Advanced degeneration of the extensor apparatus (patella tendon; quadriceps tendon) with or without discontinuity, following revision arthroplasty. CONTRAINDICATIONS: Persistent infection or pending TKA revision...

BACKGROUND: The posterior flap is a conventional technique for closing a below-knee amputation (BKA) that uses the gastrocnemius and soleus muscle and relies on the popliteal and posterior compartment arteries. If the prior mentioned arterial blood supply is compromised, this flap likely relies on collateral flow. The purpose of this study is to identify and differentiate any significant associations between preoperative popliteal and tibial arterial flow and BKA outcomes and patient-reported function...

PURPOSE: To investigate the clinical effect of gastrocnemius muscle flaps combined with vancomycin/gentamicin-calcium sulfate combined and autologous iliac bone graft in the phase I treatment of traumatic focal osteomyelitis (Cierny-Mader type III) after tibial plateau fracture surgery. METHODS: From July 2009 to January 2018, 35 patients with localized osteomyelitis (Cierny-Mader type III) who met the inclusion criteria were followed up and treated. All patients were infected after undergoing internal fracture fixation surgery...

BACKGROUND: Open proximal tibial fractures accompanied by soft tissue loss are substantially challenging to accomplish both bony consolidation and wound healing. The authors retrospectively delineated the utility of the various forms of the gastrocnemius muscle in fix & flap regimen for management of such complicated injuries. METHODS: Thirty-one patients with open fracture accompanied by soft tissue loss of proximal tibia were managed by the protocol of fix & gastrocnemius flap...

BACKGROUND: The medial sural artery perforator free flap (MSAP) has gained increasing popularity in head and neck reconstruction. Its slightly bulkier nature than the radial forearm flap, combined with negligible donor site morbidity, makes it an ideal candidate for the reconstruction of partial glossectomy defects. The ability to harvest the MSAP as a chimeric flap with a portion of the medial gastrocnemius muscle gives it greater flexibility in soft tissue reconstruction. METHODS: A retrospective study of patients with partial glossectomy defects reconstructed using the MSAP by a single surgeon was performed...

Soft tissue defect coverage has always been a challenge for the orthopaedic surgeon. Over the last decades the surgery of flaps has completely changed the prognosis for large defects. The purpose of this study is to retrospectively review our experience with the gastrocnemius muscle as pedicled local flaps for reconstruction of knee and upper third of the tibia soft tissue defects. Twenty-seven patients underwent reconstruction of soft tissue defects around the knee using pedicled gastrocnemius muscle flaps...

Amputation after open tibial fracture occurs in 3% of cases. The rate increases when flap reconstruction is required. The standard care involves microsurgical tissue transfer although the pedicled reverse sural artery adipofascial flap (PRSAF) is a local alternative in patients endangered by a prolonged operative time. Incorporation of a gastrocnemius muscle cuff in this flap can be used to fill dead space and increase healing potential. Literature shows superior survival rates for both PRSAF and inclusion of a muscle cuff in comparison with the cutaneous version...

Objective: To explore the clinical treatment of incision infection wounds after orthopedic internal fixation for lower extremity joint injuries. Methods: A retrospective cohort study was conducted. From February 2014 to December 2019, 214 patients with lower limb closed injury were treated in Beijing Jishuitan Hospital, including 143 males and 71 females, aged from 16 to 65 years. The patients all underwent orthopedic internal fixation, after which 42 cases of postoperative wounds of patellar fracture, 30 cases of postoperative wounds of tibial plateau fracture, 72 cases of postoperative wounds of Achilles tendon rupture, 45 cases of postoperative wounds of calcaneal fracture, and 25 cases of postoperative wounds of Pilon fracture were caused by incision infection, including 31 cases of superficial infection and 183 cases of deep infection...

Medial sural artery perforator (MSAP) flap is a thin, pliable, and versatile flap. It is a fasciocutaneous flap with chimeric design capacity. The donor site permits the synchronous harvesting of nonvascularized tendons and nerves. Free MSAP flap is suitable for foot, ankle, and distal one-third of the leg reconstructions. Pedicled MSAP flap is an alternative flap for knee and proximal two-thirds of leg defects, covering classical lower limb reconstruction territories of soleus, medial, and lateral gastrocnemius muscle flap...

BACKGROUND: Extensive research has been conducted on islet transplantation as a possible cure for diabetes. Islet transplantation in the liver via the portal vein has shown remarkable results, but numerous other recipient sites are currently being investigated. We aimed to show the effectiveness of using a muscle flap as a recipient site for islet transplantation. METHODS: Islet cells were harvested from 12 isogenic Lewis rats, and then diabetes was induced in another 12 isogenic Lewis rats by streptozotocin injection...

Inferiorly based gastrocnemius muscle flaps have been successfully used to cover soft tissue defects of the middle third of the leg. This is done especially in older patients or patients with major complications where operative time should be limited. We aimed to determine the gastrocnemius muscle length that can be safely used for preparing inferiorly based muscle flaps. Methods: We performed angiographies and dissection to investigate the numbers and distribution of the communicating arterial branches between the medial and lateral heads of the gastrocnemius muscle, and the perforating arterial branches of the medial sural artery from the soleus to the gastrocnemius muscles on 18 legs of preserved cadavers...

BACKGROUND: Posttraumatic patella osteomyelitis is rare, and the treatment of osteomyelitis remains to be challenging. Control of the infection commonly costs a long time, and it is easily to cause knee stiffness. In addition, there is no unified protocol for the treatment of knee stiffness. CASE PRESENTATION: We reported a case of posttraumatic patella osteomyelitis that successive infected with methicillin-resistant staphylococcus aureus (MRSA) after multiple surgeries...

Lower limb salvage in severely injured burned patients with bone or tendon exposure may be a reconstructive challenge. In this cases, local or regional flaps and other more conservative therapies such as dermal substitutes and negative-pressure wound therapy are usually not available or are not good enough to solve the problem. In such situations, microsurgical reconstruction with distant flaps seems to be the best option, even though the particularities of the severe burn patient may decrease free flaps' success rate...

Soleus muscle flap as coverage tissue is a possible surgical solution adopted to cover the wounds due to open fractures. Despite this procedure presents many clinical advantages, relatively poor information is available about the loss of functionality of triceps surae of the treated leg. In this study, a group of patients who underwent a soleus muscle flap surgical procedure has been analyzed through the heel rise test (HRT), in order to explore the triceps surae residual functionalities. A frequency band analysis was performed in order to assess whether the residual heads of triceps surae exhibit different characteristics with respect to both the non-treated lower limb and an age-matched control group...

Objective: To explore the effect of a delayed pedicle gastrocnemius muscle flap transposition for the treatment of a knee joint deep infection secondary to wound necrosis after total knee arthroplasty (TKA). Methods: The clinical data of 7 patients treated in Shanxi Provincial People's Hospital with a delayed pedicle gastrocnemius muscle flap transposition from December 2015 to September 2019 for wound necrosis, exposed prosthesis and deep infection of knee joint after TKA were analyzed retrospectively. Before the muscle flap transplantation, 5 of the patients had received at least one debridement but failed for relapse, and resulted in an exposed prostheses and infected knee joint...

The gastrocnemius flap is a versatile flap when muscle, or, muscle and skin is desired for coverage of bone of the proximal one-third of the leg, and about the knee. Both the medial and lateral heads, or both combined, may be used as flaps. Typically, the reach of only the muscle will restrict reach to just below the knee. Release off the medial femoral condyle permits increased reach, and a bit more is obtained by scoring the deep fascia and gently slow expansion of the muscle.

Microsurgical free tissue transfer is still playing an important role in lower extremity reconstruction. Finding a suitable recipient artery for anastomosis is critical in the microsurgical procedure, especially in an extensive wound, or in a complex trauma combined with vascular injury. From April 2014 to March 2018, we retrospectively reviewed patients with traumatic/post-traumatic, oncologic, and electrical wounds in the lower extremity. Those treated with muscle feeding artery as recipient vessels were included...
