Arthroscopic Flexor Halluces Longus Transfer and Percutaneous Achilles Tendon Repair for Distal Traumatic Ruptures.

The Achilles tendon is the largest and strongest tendon in the human body. It is the tendon that most often suffers injury and accounts for 20% of all tendon ruptures. These types of ruptures often occur 2 to 6 cm proximal to the stumps in an area of reduced vascularity. One such injury, the distal acute Achilles tendon rupture, is quite uncommon. For distal repairs, there have been studies that used a pullout technique, a button technique, and the use of local tendons for open-fashion augmentation. Although percutaneous repair and endoscopic flexor hallucis longus (FHL) tendon transfer techniques have been described for both acute midportion and chronic Achilles tendon rupture repair, there are no studies that describe the use of percutaneous sutures and biological augmentation with FHL transfer as a treatment option for acute distal injuries. The purpose of this Technical Note is to describe a novel approach to repair. It combines arthroscopic FHL tendon transfer with a percutaneous Achilles tendon repair technique for traumatic distal ruptures.

Free vascularized iliac periosteal graft for bilateral forearm nonunion reconstruction in a child with bilateral transfemoral amputation.

Vascularized periosteal flaps have been reported as very effective for treating biologically complex bone nonunion in pediatric patients, owing to their high angiogenic and osteogenic potentials. The purpose of this article is to report a case of a 6-year-old patient with nonunion involving both forearms and a very limited bone flap donor site in the context of prior bilateral transfemoral amputation due to meningococcal sepsis. Two free vascularized iliac periosteal flaps (VIPF), supplied by the deep circumflex iliac vessels, were used in two stages to reconstruct the forearms. In the first stage, the left forearm, which had a diaphyseal bone defect of 5 cm diameter in the ulna and 4 cm in the radius, was combined with an iliac-crest bone allograft, fixed with two longitudinal 1.8 mm Kirschner wires and surrounded with a free VIPF of 24 cm2 . Consolidation was achieved 3 months after left forearm surgery, while complete allograft revascularization and remodeling was observed at 12 months. In the second stage, the right forearm, which had a diaphyseal bone defect of 3 cm diameter in the ulna and 1 cm in the radius, was fixed the radius with a 2.7 mm plate and surrounded with a free VIPF of 24 cm2 . The radius nonunion healed 6 weeks after surgery. There were no postoperative complications. Two years postoperatively, the patient had again resumed his arm gait painlessly and without a splint. VIPF may be considered a valuable and reliable surgical option for nonunion reconstruction in complex clinical scenarios in children.

Local Percutaneous Radiofrequency for Chronic Plantar Fasciitis.

Plantar fasciitis is the most common cause of heel pain. It accounts for 80% of the cases and has an estimated prevalence rate of up to 7% in the general population, with bilateral involvement in 20% to 30% of those patients. This condition affects people of working age, thereby limiting and diminishing their quality of life. There are a wide range of treatment options for the management of plantar fasciitis that include both conservative and surgical treatments. Although surgical treatment based on partial or total plantar fascia release has success rates of some 70% to 90%, it is not free of complications. These complications, soft-tissue healing problems, superficial infection, or longitudinal arch collapse in cases of a greater than 40% release of the fascia. Bipolar radiofrequency appears to be a safe procedure for refractory plantar fasciitis that can provide outcomes equivalent to open plantar fascia release with less morbidity. The purpose of this article is to describe the local percutaneous radiofrequency technique for patients with chronic, recalcitrant plantar fasciitis.

Accidents and injuries in elite MotoGP motorcycle riders.

OBJECTIVE: Evaluating incidence, characteristics and risk factors of accidents and injuries in each elite motorcycle racing class (MotoGP, Moto2 and Moto3), 2013-2017. DESIGN: Descriptive epidemiological study. SETTING: MotoGP Medical Team, Dorna Sports SL. PARTICIPANTS: Competing riders in elite motorcycling racing classes, 2013-2017. INTERVENTIONS: Benchmarking incidence, characteristics and risk factors of accidents and injuries in each elite motorcycle racing class, 2013-2017. MAIN OUTCOME MEASURES: Association between accident type (by class and year) and fracture, withdrawal from race, need for surgery, injuries (fractures or contusions/wounds) and time riders kept inactive. Circuit and curve, weather conditions, presence and type of fracture, clinical outcome, and time until return to competition. Event outcomes were defined as rider fit/rider unfit after each accident. Racing class, track curves and circuits with the most and fewest accidents, circuit characteristics, speed and deceleration, G-forces, and time race differences between classes. RESULTS: 9092 accidents (mean 1818,4 per year). Most during race and under wet-weather conditions. Class and circuit with most accidents 2013-2017 were Moto3 (3374; 37.11%) and MWC - Marco Simoncelli -with 430.119/9092 accidents resulted in a fracture (1.31%), 83, surgical fractures (70%). Most frequent surgical fractures were upper extremity (clavicular; 29/119; 21%). On average, riders returned to competition after two circuits (1-5 weeks). CONCLUSIONS: Accidents are not uncommon among elite motorcycle riders; incidences of fractures and surgical fractures are low. Factors such as weather conditions and circuit's characteristics influence the risk of accidents. Further research is necessary to clarify the magnitude of the role each of these factors play.

Two-Portal Endoscopic Plantar Fascia Release: Step-by-Step Surgical Technique.

Plantar fasciitis is a common condition of heel pain with a lifetime incidence up to 10%. For this entity, conservative treatment is considered the gold standard, involving non-steroidal anti-inflammatory drugs, stretching exercises of the plantar fascia, activity modifications, ice, and insoles. When patients do not respond to these treatments, partial or total plantar fascia release has been the mainstay of treatment, with success rates of approximately 70% to 90%. For this purpose, several techniques have been described, including open, percutaneous, and endoscopic release. The objective of this Technical Note is to describe the nonassisted 2-portal endoscopic plantar fascia release in a patient with recalcitrant plantar fasciitis.

Retrograde Drilling With Tibial Autograft in Osteochondral Lesions of the Talar Dome.

Osteochondral lesions that compromise the ankle are rare, with an incidence between 0.02% and 1.5% according to different series. This location is the third in frequency, after knee and elbow. The location of the osteochondral lesion allows one to infer the producing mechanism. Lateral defects are produced by inversion and dorsiflexion of the ankle (usually anterior, affecting 3 and 6 talar zones), whereas medial defects are produced by plantar flexion, inversion, and internal rotation (most commonly posterior, affecting 4 and 7 talar zones). The injury causes pain associated with weight load, impaired function, limited range of motion, stiffness, blockage, and edema. Early diagnosis of an osteochondral lesion is particularly important because the lack of diagnosis can lead to the evolution of a small and stable lesion in a larger lesion or an unstable fragment, which can result in chronic pain, instability of the joint, and premature osteoarthritis. Multiple therapeutic strategies have been described, including conservative and surgical treatment. The purpose of this Technical Note is to describe arthroscopic-assisted retrograde drilling with tibial autograft procedure for osteochondral lesions of the talar dome.

Are Vascularized Periosteal Flaps Useful for the Treatment of Difficult Scaphoid Nonunion in Adults? A Prospective Cohort Study of 32 Patients.

PURPOSE: To evaluate clinical and radiological outcomes after surgical treatment of difficult scaphoid nonunion in adults with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF). MATERIALS AND METHODS: Thirty-two patients at least 18 years old, with scaphoid nonunion and characteristics associated with a poor prognosis, who underwent a VTMPF procedure, were included in this retrospective cohort study with a mean follow-up of 17 months. Factors associated with a poor prognosis were a delay in presentation of over 5 years, the presence of avascular necrosis, and previous nonunion surgery. All patients had at least 1 poor prognostic factor and 25% had 2 or more. RESULTS: In 30 men and 2 women, the mean age was 36 years (range, 19-56 years). There were 11 type D3 nonunions (Herbert classification) and 15 type D4. Five patients had delayed presentation of over 5 years. Fourteen patients had previously undergone an unsuccessful surgical attempt to treat their nonunion. The patients experienced no postoperative complications. Overall union rate was 97% (31 of 32 patients), with 72% cross-sectional trabecular percentage bridging at 12 weeks. Pain subsided after surgery and patients experienced improvements in both their Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Modified Mayo Wrist Score (MMWS). Overall 41% and 42% gains in strength and wrist motion, relative to the contralateral normal side, were observed. At final follow-up, there were no differences between the treated and the untreated (healthy) hands, in terms of wrist range of motion, grip, or pinch strength. CONCLUSIONS: In this study, the use of VTMPF for difficult scaphoid nonunion in adults was associated with good general outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Retrograde intramedullary headless compression screws for treatment of extra-articular thumb metacarpal base fractures.

The purpose of the study was to evaluate clinical and radiological outcomes of extra-articular fractures involving the base of the thumb metacarpal treated with fixation using a retrograde intramedullary cannulated headless screw. A review of prospectively collected data was conducted on a consecutive series of 13 patients, treated with headless screw fixation for acute displaced fractures. All workers resumed full duties, while non-workers returned to unlimited leisure activities within a mean of 42 days. At 3 months follow-up, all range of motion measurements in the treated and untreated thumb were similar. Mean visual analogue pain score was 0.8 at rest and 1.4 during exercise and mean Quick Disabilities of the Arm, Shoulder, and Hand score was 5. All patients achieved radiographic union by 8 weeks. We conclude that the intramedullary headless screw fixation is safe and reliable for base of thumb metacarpal fractures, allowing for early postoperative motion and good functional recovery. Level of evidence: IV.

Inter-implant fractures: an unmet medical need-a preventive approach proposal.

Inter-implant fractures are associated with reduced quality of life and increased 1-year mortality. For that reason, we propose, instead of treating, a novel, preventative surgical approach that involves splinting the inter-implant femoral shaft interval. In patients with a previous femoral implant in whom a second surgery for new material implantation was necessary (including knee or hip arthroplasty, plate or femoral nailing), an overlapping technique using the minimally invasive plate osteosynthesis technique was performed during the second surgery. Nine patients were included, all females with median (range) age of 78 (55-88) years. No surgery-related complications or mortality occurred. Two patients suffered fractures from a casual fall postoperatively with no implant failure or hospital admission required. In conclusion, instead of treating such fractures after they occur, we propose an effective, safe and reproducible preventative surgical approach, not previously reported, which involves internal femoral splinting, a plate and the minimally invasive plate osteosynthesis technique.

Dorsolateral Biplane Closing Radial Osteotomy and Lunate Fixation for Stage IIIC Kienböck Disease: A New Surgical Approach.

The treatment of advanced-stage Kienböck disease (KD) remains highly controversial. Particularly important is stage IIIC KD, which includes patients with a lunate coronal fracture. The purpose of this paper was to describe a new approach to KD in patients with Lichtman stage IIIC KD, and our results using it. The procedure combines a dorsolateral biplane closing radial osteotomy and lunate fixation. A total of 11 patients from January 2002 through December 2016 with documented KD who underwent this technique were included. The patients were assessed before surgery, then postoperatively at 1 and 10 days, 3 and 6 weeks, 3 and 6 months, and annually. Wrist range of motion, grip and pinch strength, the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, a Modified Mayo Wrist Score (MMWS), 10-point visual analog scale, radiologic measurements, and data related to consolidation were collected. All statistical analyses were performed using the statistical software package SPSS. Some degree of pain relief, improvements in the QuickDASH score, MMWS score, grip strength, and the degrees of flexion and extension were observed, the results being statistically significant (P<0.05). After surgery, the values for radial and sagittal tilt were statistically different than those measured before surgery. Carpal collapse was not evident either before or after surgery. In conclusion, combining a dorsolateral radial osteotomy and a lunate compression screw may expand the options for patients with Lichtman stage IIIC KD. Our experience indicates that it is a viable option in challenging clinical scenarios.

TRest as a New Diagnostic Variable for Chronic Exertional Compartment Syndrome of the Forearm: A Prospective Cohort Analysis of 124 Athletes.

OBJECTIVES: To measure the accuracy of currently used intracompartmental pressure (ICP) diagnostic variables for forearm chronic exertional compartment syndrome (CECS) and a new ICP diagnostic variable, TRest, the recovery time between the maximum ICP and return to resting pressure. DESIGN: Retrospective cohort. Level evidence IV. SETTING: University-affiliated tertiary hospital. PARTICIPANTS: Patients with suspected forearm CECS, 1990 to 2014. INTERVENTIONS: All patients underwent physical examination and exertional stress test, preceded and followed by measuring ICP in all suspicious CECS. Surgery was proposed when indicated. Minimum follow-up was 18 months. Final diagnosis was established at the final follow-up. MAIN OUTCOME MEASURES: Intracompartmental pressure measurements: PRest (baseline/pre-exercise pressure), P1 min (pressure 1 minute after exercise), P5 min (pressure 5 minutes after exercise), and TRest. Patients rated their pain and completed Quick-DASH in all follow-ups. Patients ultimately were classified into 4 groups (true positives, true negatives, false positives, and false negatives) for each ICP measurement relative to the final diagnosis. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. RESULTS: A total of 124 male athletes were diagnosed with CECS, 27 bilateral. Accuracy with standard ICP diagnostic variables was lower (sensitivity 73.5%, specificity 84.2%, positive predictive value 97%, and negative predictive value 31.4%) than with TRest (SN 100%, SP 94.7%, PPV 99.3%, and NPV 100%); 23% of patients would have been missed following the standard ICP diagnostic criteria. CONCLUSIONS: Diagnostic thresholds for current standard ICP measurements should be lowered. TRest, a new measure, might be more accurate.
