Background Open repair of Achilles tendon rupture has been associated with higher levels wound complications than those percutaneous repair. However, some studies suggest there are rerupture rates and sural nerve injuries Questions/purposes We compared the two types repairs in terms (1) function (muscle strength, ankle ROM, calf perimeter, single heel rise tests, work return), (2) cosmesis (length scar, cosmetic appearance), (3) complications. Patients Methods retrospectively reviewed 32...
Three-dimensional (3D) printing is a technique based on overlapping layers of material (eg, plastic, clay, and metal). The widespread implementation 3D printers has resulted in notable increase use. Fields such as construction, engineering, medicine benefit from this technique.The use printed scale models permits better surgical planning results.The were created CT images seven patients (age range, 5 to 61 years) with different pathologies who candidates for surgery.Surgical time decreased...
Instability is a common sequela after repeated ankle sprains. When nonoperative treatment fails, open lateral ligament complex repair and reinforcement with the inferior extensor retinaculum has been gold standard procedure. The recent advancements in arthroscopic techniques have created comparable biomechanical functional results to procedures. authors' modification technique permits approximation distal fibula over larger surface area, using knotless anchors avoid need of an accessory...
Background: Total ankle arthroplasty is associated with severe postoperative pain. Development of analgesic techniques such as a block continuous infusion at the popliteal level has been shown to result in good pain control, decrease use rescue analgesia and low rate complications. We reviewed our experience this method patients who underwent total arthroplasty. Methods: A prospective study 30 undergoing was carried out. Twenty-two these received maintained bupivacaine, while remaining eight...
Objective: The purpose of the study was to evaluate early clinical and radiological results with a novel minimally invasive surgery (MIS) technique for Lapidus arthrodesis using intramedullary nail. Methods: Retrospective review patients hallux valgus during an 18-month period. Patients procedure other than MIS nail fixation were excluded. We describe surgical percutaneous joint preparation through approach. Demographic variables, complications radiographic parameters measured. Results: Ten...
Hallux valgus (HV) is a complex deformity, with many associated risk factors. The flexor hallucis longus (FHL) tendon dynamic and potentially deforming force as it bowstrings laterally HV. We hypothesized that FHL more inserted in the distal phalanx cadavers HV; therefore, might be also primary destabilizing force. aim to compare insertion morphology its relationship osseous structures without
Category: Ankle Arthritis; Introduction/Purpose: Osteoarthritis (OA) of the tibiotalar joint is associated with a high degree morbidity, comparable to final stages renal and heart failure. The incidence OA in as 47.7 per 100,000 inhabitants, most whom will require surgical intervention improve their quality life. To date, there scarce literature on alignment Total Arthroplasty (TAA) its implications for patient-reported outcome measures (PROMs). Furthermore, no evidence has yet analyzed...
The purpose of this protocol was to adapt and validate the English version Short Musculoskeletal Function Assessment (SMFA) into Chilean Spanish according World Health Organisation guidelines. This is a cross-sectional study 897 surveys patients with non-traumatic surgical orthopaedic pathologies. We analysed internal consistency, validity, acceptability, including correlation short form 36 (SF-36) medical score. validation included 900 participants response rate 99,66%, excellent...
Objective: Describe flexor hallucis longus (FHL) distal insertion. Methods: Ten cadaver feet were dissected to evaluate FHL insertion, the width of and distance between insertion borders medial-lateral phalangeal borders. Results: All specimens showed a lateral tendon fascicle inserted more than main The mean medial border was 3 mm 5.2 mm. long axis 12.36% laterally deviated at metatarsophalangeal (MTP) joint 14.07% interphalangeal (IP) joint. Conclusion: has closer phalanx border, its...
Category: Sports Introduction/Purpose: Study Design: Case-control Objective: To determine whether patients presenting with an Achilles tendon rupture are at greater risk of rupturing their contralateral when compared to general population. Summary Background Data: Extrinsic factors for rupture, such as fluoroquinolones or local injections corticosteroids, well recognized. Genetic predisposition is another factor that has been proposed, since this pathology more frequently seen in certain...
Surgical treatment remains the standard of care for active patients with acute midsubstance Achilles tendon ruptures. Minimal invasive surgery, rupture’s site hematoma preservation, strong fixation, avoidance sural nerve entrapment, and early rehabilitation are essential concepts desirable any repair. Hereby, we present a technique modification that incorporates all these advantages in one single procedure.
Level of Evidence: V.
Category: Sports Introduction/Purpose: Chronic? exercise-induced compartment syndrome (CEICS) is a commonly misdiagnosed source of pain. Although CEICS seen infrequently in the general population, its incidence high-performance athletes estimated to be 0.49 per 1000 year. Delayed diagnosis should avoided, as irreversible sequelae can result, often causing sports retirement. We present our experience and treatment CEICS. Methods: After IRB approval, we conducted retrospective patient chart...
Tendon ruptures around the foot and ankle are relatively common frequently misdiagnosed, causing patient consultation in chronic scenario. A widely vary of surgical techniques have been described for tendon reconstruction. To our knowledge there is no gold standard procedure, several drawbacks associated with that uses nearby tissue reconstruction due to sacrifice healthy structures can imbalance loose strength. In consequence, allografts appear as an attractive alternative less morbidity...
Achilles tendinopathy is a very common pathology, especially in the athletic population. Its etiology multifactorial and underlying pathophysiology still not fully understood. For non-insertional increasingly recognized influence of paratendinopathy genesis patients symptoms, so various surgical treatments have been accordingly developed; they are indicated when conservative treatment fails. The tendoscopy one these techniques, it has advantages minimally invasive surgery, resulting low...
We describe the surgical technique, assessment, and complications in patients undergoing arthroscopic reduction internal fixation for distal tibial intra-articular fractures. Between December 2005 September 2010, 8 underwent surgery. Mean follow-up time was 44 months (range, to 65 mo). age years 35 y); 7 were male. AO classification 4.3.C.1 3 4.3.C.3 5. Anatomic successfully achieved all patients. Consolidation between 6 cases. During follow-up, no loss of identified by x-ray. One patient...
