Time until union in absolute vs. relative stability MIPO plating in simple humeral shaft fractures.

PURPOSE: The objective of this study is to evaluate the effect of absolute stability (AS) versus relative stability (RS) performed through a minimally invasive plate osteosynthesis (MIPO) in AO/OTA 12A1 and 12A2 fractures on healing and the time to radiographic union. METHODS: This was a retrospective cohort study of all patients treated with plate fixation for AO/OTA type 12A1-A2 fractures at a single institution. Patients were grouped according to the type of stability used in their surgery. Time until radiographic union was estimated using the Kaplan-Meier method, which was compared by long-rank test between both types of surgical techniques. RESULTS: A total of 70 patients were included in this study with 35 patients in each group. The median follow-up was 9 (IQR 6-14) months. The median time to radiographic union was significantly lower in the AS group than in the RS group: 12 (interquartile range (IQR) 10-14) weeks versus 18 (IQR 16-19) weeks, respectively (p < 0.001). Non-union was seen in two cases (7%) in the relative stability group. Three patients in the RS group developed a post-operative radial nerve palsy. CONCLUSION: The main finding of this study is that the median time to radiographic union was significantly shorter in the patients treated with AS compared to those with a RS technique. These findings support the recommendations of the AO foundation in that simple metaphyseal fractures (type A) that require surgical treatment should be treated with an AS construct. RS techniques should be reserved to multifragmentary fractures where fragment preservation of blood supply is paramount.

Radius Core Decompression for Kienböck Disease Stage IIIA: Outcomes at 13 Years Follow-Up.

PURPOSE: This study was designed to analyze the long-term clinical and radiological outcomes of a series of patients with Kienböck disease stage IIIA treated with radius core decompression. METHODS: This retrospective study included 15 patients with Kienböck disease (Lichtman stage IIIA) who underwent distal radius metaphyseal core decompression between 1998 and 2005 and who were followed-up for at least 10 years. At the last follow-up, the patients were evaluated for wrist range of motion and grip strength. The overall results were evaluated by the modified Mayo wrist score and visual analog scale pain score. We also compared the radiological changes between the preoperative and the final follow-up in their Lichtman classification and the modified carpal height ratio. RESULTS: The mean follow-up period was 13 years (range, 10-18 years). Based on the modified Mayo wrist score, clinical results were excellent in 6 patients, good in 8 patients, and poor in 1 patient who required a proximal row carpectomy as revision surgery. The mean preoperative pain according to the visual analog scale was 7 (range, 6-10) and was 1.2 (range, 0-6) at the final follow-up. Compared with the opposite side, the average flexion/extension arc was 77% and the grip strength was 80%. All patients, except 1, returned to their original employment. At the final follow-up, 3 patients had decreased modified carpal height ratio, 12 remained unchanged. Radiographic disease progression according to the Lichtman classification to stages IIIB to IV occurred in only 2 wrists. There were no complications related to the core decompression. CONCLUSIONS: In this limited series, the radius core decompression demonstrated favorable long-term results and could be considered as a surgical alternative for stage IIIA of Kienböck disease. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

The use of dynamic orthoses in the treatment of the stiff elbow.

The purpose of this study is to evaluate the outcomes of the treatment of stiff elbow with the use of dynamic orthoses. We included 30 patients with stiff elbow with an arc of mobility of 100° or less and a stable and congruent joint without heterotopic ossifications. The dynamic orthosis was designed in our service and consists of an articulated brace with springs. Mean previous mobility was 109°-41°, with an average arc of motion of 68°. Its use began 78 days after surgery or trauma and continued for 75 days. Statistical analysis was performed. Average follow-up was 23 months. Postoperative mobility was 126°-21° with an improvement of 37° of mobility. Ten patients did not recover a functional range of motion. Twenty-three patients were satisfied with the treatment and seven were unsatisfied with the use of the orthosis. Our results suggest that dynamic orthoses are useful in the treatment of stiff elbow. We achieved a mean improvement of 37° in the arc of motion, which in many cases has rendered arthrolysis unnecessary. The major strength of this paper is the practical application of the orthosis and its relatively easy manufacture.

Fibula flap in upper extremity segmental/critical size bone defects fixed with locking plates. Single-institution observational cohort.

INTRODUCTION: Management of bone defects in the upper extremity can vary depending on the size and location of the defect. Large defects may require complex reconstruction techniques. Vascularized bone grafts, mainly free vascularized fibula flap (FVFF), have many advantages in the treatment of bone or osteocutaneous defects. However, complications such as graft fracture are the most common, with a free fibula flap for bone defects in the upper extremity. This study aimed to describe the results and complications associated with the treatment of posttraumatic bone defects in the upper extremity using FVFF. We hypothesized that performing osteosynthesis using locking plates would prevent or reduce the fracture of the fibula flap MATERIALS AND METHODS: This was a retrospective single-centre cohort study. Patients with segmental bone defects caused by trauma who underwent reconstructive surgery with FVFF fixed with locking compression plates (LCP) between January 2014 and 2022 were included. Demographic variables and preoperative data, such as bone defect, location, and time until reconstruction, were collected. Bone defects were classified according to the Testworth classification. Intraoperative variables included the length of the FVFF, type of graft (osteocutaneous or not), type and technique of arterial and venous sutures, number of veins used as output flow, and the osteosynthesis technique used. RESULTS: Ten patients were included (six humerus, three ulna, and one radius). All patients had critical-size bone defects, and nine patients had a history of infection. In 9 of 10 patients, bone fixation was performed with a bridge LCP and in one patient with two LCP plates. In eight cases, the FVFF was osteocutaneous. All the patients showed bone healing at the end of the follow-up period. There was one early complication, donor site wound dehiscence, and two long-term complications (proximal radioulnar synostosis and soft-tissue defect). CONCLUSION: A high rate of bone union with a low rate of complications can be obtained with an FVFF in upper extremity segmental/critical-size bone defects. Rigid fixation with locking plates avoids stress fractures of the grafts, mainly in humeral reconstruction. However, in these cases, a bridge plate should be used.

What Is the Infection Rate of Carpal Tunnel Syndrome and Trigger Finger Release Performed Under Wide-Awake Anesthesia?

BACKGROUND: High infection rates have been reported in hand procedures using the wide-awake local anesthesia no tourniquet (WALANT) method, causing some to question the validity of this approach. However, little evidence exists surrounding the direct use of WALANT compared with monitored anesthetic care (MAC). This study was conducted to directly compare the postoperative infection rates of carpal tunnel syndrome (CTS) and trigger finger (TF) release surgeries performed under WALANT and MAC. METHODS: A retrospective study comparing postoperative infection rates between patients undergoing CTS and TR releases was conducted. Our primary outcome measure was postoperative infection. Our secondary outcome was postoperative complications. Comparative statistics were used to compare means of infection between the groups. RESULTS: A total of 526 patients underwent CTS release (255 with WALANT and 271 with MAC), and 129 patients underwent TF release (64 with WALANT and 65 with MAC). Patients undergoing WALANT and MAC were statistically comparable in terms of sex, smoking status, diabetes, and American Society of Anesthesiologists physical status classification. In patients undergoing CTS release, there were no infections with WALANT and 6 infections (2.2%) with MAC. In patients undergoing TF release, there were no infections in either group. There were similar rates of complications in patients undergoing WALANT and MAC for CTS and TF releases. CONCLUSION: There was no increased risk of infection with WALANT compared with MAC in CTS or TR surgeries. These surgeries can be safely conducted with lidocaine and epinephrine without a concern for increased risk of infections or complications.

Total Elbow Arthroplasty in the Context of an Olecranon Nonunion: A Surgical Technique and Report of Three Cases.

The deficiency of the triceps tendon has been considered a relative contraindication to performing a total elbow arthroplasty. One of the conditions that may compromise triceps integrity is the presence of an olecranon non-union (ON). In this scenario, the placement of a total elbow arthroplasty in a patient with end-stage elbow arthritis is a complex problem to be solved. The aim of this study is to describe the surgical technique for the placement of a TEA in the context of a previous ON and to report the results of three cases. Surgical technique: the focus of the nonunion is identified, and the olecranon fragment is proximally reflected with the triceps tendon to allow accurate exposure of the medullary canal of the ulna and easy access to the joint. With the elbow in a fully flexed position, the previously assembled test prosthesis is placed and the proximal ulna fragment should then be reduced to match the distal ulna. Osteosynthesis with a tension band technique was performed at 45° of elbow extension. A non-absorbable Krackow suture (Ti-Cron 2-0) from the triceps's tendon to the hole of the wire in the distal ulna is applied to decrease the triceps tension traction. Bone grafting is performed when a persistent gap is present at the fracture site following reduction. This technique enables us to achieve a stable elbow with little pain and maintains the extensor apparatus's continuity.

Description of unusual osteochondral laminar fragment patterns in Distal Radius fractures.

BACKGROUND: Distal radius fracture (DRF) is one of the most common fractures and, frequently, surgical treatment is mandatory in the presence of an intra-articular fracture. However, there are some unusual intra-articular fracture patterns, were it remains challenging to properly recognize and anatomically reconstruct the articular surface. The objective of the present study is to describe an intra-articular fracture pattern of the distal radius characterized by the presence of osteochondral laminar fragments, which could potentially require a different treatment to standard stabilization. We aim to answer the following questions: (1) What are the radiological characteristics of intra-articular DRFs with osteochondral laminar fragments (OCLF), (2) What is the prevalence of DRFs with OCLF relative to all intra-articular surgical DRFs, (3) What are the differences in epidemiological characteristics of patients with OCLF in relation to all patients with intra-articular DRFs, (4) What is the prevalence of intra-articular DRFs with OCLF in patients belonging to a closed community. PATIENTS AND METHODS: We reviewed radiological and tomographic records of all adult patients operated on distal radius fractures at our institution. We analyzed tomographic characteristics; prevalence of osteochondral laminar fragments relative to all intra-articular surgical distal radius fractures and compared clinical and demographic characteristics of patients with osteochondral laminar fragments in relation to all patients with intra-articular fractures. RESULTS: Two main groups according to the fracture pattern were described: group I, volar rim impacted OCLF (vOCLF); and group II, central impacted OCLF (cOCLF). Prevalence of OCLF relative to surgical intra-articular DRFs: 42/989 (4.2%); group I: 23/989 (2.32%); group II: 19/989 (1.92%). Characteristics of patients with OCLF compared to all patients with intra-articular DRFs: Significant differences were found in the five variables evaluated (age, less than 65 years, female, high energy fracture, and associated fractures). The global prevalence of DRFs with OCLF in patients affiliated with the medical care insurance system of our institution was 2 per 10,000 individuals (95% CI 1.4 to 2.9). DISCUSSION: Global prevalence of these fragments relative to surgical intra-articular fractures was very low. However, despite being epidemiologically rare, it is important to identify these specific fracture patterns because their treatment can be challenging.

Trapeziometacarpal osteoarthritis: Arthroscopic hemitrapeziectomy using the Thenar Portal.

BACKGROUND: Although the standard 1Radial and 1Ulnar portals allow for visualisation of most of the trapezium articular surface, the proximity of these two portals can often make arthroscopic triangulation and visualisation of the most lateral capsule and joint surface challenging. Despite its already reported advantages in improving visualisation, there is little literature reporting the clinical experience with the Thenar Portal. The purpose of this study is to describe potential complications and the short-term clinical-radiographic outcomes of arthroscopic hemitrapeziectomy using the Thenar Portal in order to determine its safety and efficacy as a standard working portal. PATIENTS AND METHODS: A retrospective chart review was conducted for all patients diagnosed with first carpometacarpal (CMC) osteoarthritis who were treated surgically with an arthroscopic hemitrapeziectomy. Only patients with stage II or III osteoarthritis and a minimum of 1-year follow-up were included. Twenty-two patients (24 thumbs) with an average age of 62 years met the inclusion criteria. The average follow-up was 52 months. Intra-operative and post-surgical complications were recorded. Objective evaluation consisted of an assessment of range of motion (ROM), grip and pinch strength. Subjective evaluation consisted of a DASH questionnaire and the visual analog scale to score pain at rest, during activities, and function. RESULTS: There were no intra- or post-surgical complications. In one case, pain persisted with a poor functional result, requiring a revision surgery. Average range of motion (compared with the contralateral) showed a statistically significant improvement in palmar abduction and radial abduction of the CMC joint: 50° vs. 55° (p=0.01235), and 50° vs. 55° (p=0.06009), respectively. There was no statistically significant improvement in thumb adduction, grip strength, or lateral and tip-pinch. All patients achieved retropulsion with their affected thumb. According to the VAS, average rest pain improved from 7.5 to 0 (p<0.001) and from 9 to 0 (p<0.001) during activity. The average final function and QuickDASH were 9 (VAS) and 8, respectively (p<0.001). The average radiographic proximal migration of the first metacarpal was 2.9mm (range: 0.7-5.8mm). DISCUSSION: Arthroscopic hemitrapeziectomy using the Thenar portal: 1) improved visualisation of the trapeziometacarpal joint, 2) facilitated arthroscopic triangulation, and 3) represents a safe and effective alternative for the treatment of thumb osteoarthritis, with pain relief and function improvement in most patients without a higher risk of complications.

Surgical correction of "cam-type" femoroacetabular impingement: a cadaveric comparison of open versus arthroscopic debridement.

PURPOSE: The goal of this study was to compare open and arthroscopic surgical techniques for "cam-type" femoroacetabular impingement in terms of feasibility and reliability. METHODS: We used 5 fresh-frozen cadaver specimens (10 hips). Anteroposterior and cross-table radiographs were taken for each. The head-neck union diameter was measured for each. The amount of bone resection at the anterolateral quadrant of the head-neck union was planned for each, with specific references to width, length, depth, and position. One side was randomly assigned to the open group and the other to the arthroscopic group. Surgical time, position of the osteotomy, and variation of the length, width, and depth of the final osteotomy with respect to the proposed dimensions were compared. RESULTS: In all specimens partial resection of the anterior-lateral femoral head-neck junction with improvement of the femoral head-neck offset was accomplished. A statistically significant difference (P < .05) was observed for surgical time between the open and arthroscopic groups (shorter in open group). CONCLUSIONS: When comparing surgical precision, no statistically significant differences were found between the open and arthroscopic procedures in any of the measurements. The depth and width of the osteoplasty were reliably obtained by the arthroscopic technique. However, there was a tendency to underestimate the osteoplasty length with the arthroscopic procedure. Positioning the osteoplasty was also less reliable with the arthroscopic procedure than with the open procedure because of the tendency to place the osteoplasty more posterior and distally than intended. CLINICAL RELEVANCE: Surgical resection of the femoral neck prominence and/or part of the anterolateral neck has been reported to improve femoral head offset and alleviate impingement. This study attempts to document the accuracy of this resection when done arthroscopically compared with an open procedure.

Treatment of terrible triad injuries at a mean follow-up of nine years.

BACKGROUND: To evaluate the sustainability of the early clinical and radiological outcomes of terrible triad injuries at long-term follow-up. METHODS: Twelve consecutive patients who underwent fixation of terrible triad injuries with minimum of seven years of follow-up. Functional and radiological outcomes at one year and final follow-up were compared. We assessed Mayo Elbow Performance Score, Quick-Disability of the Arm Shoulder and Hand, and modified-American Shoulder and Elbow Surgeons Scores. Radiological evaluation included Broberg and Morrey classification and Hastings classification for heterotopic ossification. RESULTS: The mean age of patients was 55 years, with a median follow-up of 9.3 years. At final evaluation, mean flexion, extension, supination, and pronation were 145°, 6°, 82°, and 80°, respectively; mean Mayo Elbow Performance Score, modified-American Shoulder and Elbow Surgeons Scores, and Quick-Disability of the Arm Shoulder and Hand scores were, respectively, 97, 92, and 4.9 points. There was no statistical difference between early and final follow-up range of motion, Mayo Elbow Performance Score, and Quick-Disability of the Arm Shoulder and Hand. However, radiological changes were observed in 66% of the patients at final follow-up. Two patients underwent reoperation, with final satisfactory results. CONCLUSION: Our results suggested that using a standardized protocol, satisfactory clinical outcomes at early follow-up could be maintained over time. However, early complications and osteoarthritic changes at long-term follow-up can be expected. LEVEL OF EVIDENCE: Therapeutic IV Cases series.

Metaphyseal Core Decompression and Anterograde Fixation for Scaphoid Proximal Pole Fracture Nonunion without Avascular Necrosis.

Objective To report the consolidation rate and the results of a series of 22 patients with metaphyseal core decompression of the distal radius and an antegrade compression screw. Methods We present a prospective series of patients with scaphoid proximal pole nonunion in whom the presence of intraoperative bleeding was confirmed in both fragments. Patients with displacement, degenerative changes, fragmentation of the proximal pole, cavitation of the focus, loss of height, and necrosis, as well as those with carpal instability, were excluded. The patients were evaluated with X-rays and computed tomography to evaluate their consolidation; their mobility and fist strength were recorded and an analog visual scale (VAS) of pain at rest, pain in activity, subjective functional status, and DASH questionnaire were completed. Results Of the 23 patients, 21 accomplished union. The average follow-up was 19 months and the average final range of motion was flexion 86%, extension 85%, radial deviation 79%, ulnar deviation 84%, and grip strength 84%. The average VAS for pain at rest was 1 point, the average VAS for activity pain was 2 points, the average VAS for function was 9 points, and the average DASH score was 8. Conclusions Using this simple and reliable technique, we obtained 91% union and very good functional results. Metaphyseal core decompression of the distal radius associated with an antegrade scaphoid screw is a reasonable and effective option for the treatment of proximal pole scaphoid nonunions without avascular necrosis in carefully selected patients. Level of Evidence This is Level IV study.

Resultados de la neurólisis como tratamiento del dolor neuropático en pacientes con lesión del nervio ciático. Reporte de casos / Results of neurolysis for the treatment of neuropathic pain in patients with sciatic nerve Injury. Case report

Introducción: La lesión del nervio ciático puede ocasionar desde parestesias e hipoestesias, hasta dolor neuropático severo y parálisis. La neurólisis suele mejorar la función, el dolor y la calidad de vida de los pacientes. El objetivo de este estudio fue evaluar los resultados clínico-funcionales de una serie de pacientes con dolor neuropático por lesión del nervio ciático que no respondieron al tratamiento conservador y fueron sometidos a neurólisis. Materiales y métodos: Se analizó retrospectivamente una serie de pacientes sometidos a neurólisis del nervio ciático mayor entre marzo de 2009 y junio de 2018. El dolor pre- y posoperatorio se evaluó mediante la escala analógica visual y la escala de Likert. El tipo de dolor posoperatorio se evaluó con el cuestionario DN4 y la calidad de vida relacionada con la salud, con el cuestionario SF-36.Resultados:Se incluyó a 8 pacientes. A los 32 meses de seguimiento promedio (rango 14-66), el dolor había mejorado notablemente (promedio de 3 y 1,88 puntos en las escalas analógica visual y de Likert, respectivamente). El cuestionario DN4 arrojó un promedio de 3,75 puntos (rango 2-7). Según el SF-36, la "salud física" fue la variable con peores resultados (promedio 30,15).Conclusiones: La neurólisis, cuando se indica a pacientes con mala respuesta al tratamiento conservador, es un método que alivia el dolor y mejora la calidad de vida de los pacientes con dolor neuropático secundario a una lesión del nervio ciático.

Introduction: Sciatic nerve injury may cause paresthesias and hypoesthesias, severe neuropathic pain, and paralysis. Neurolysis can improve function, pain, and quality of life for these patients. The objective of this paper is to evaluate the clinical-functional outcomes of a series of patients with neuropathic pain due to sciatic nerve injury that was refractory to conservative treatment in whom neurolysis was performed. materials and methods:A retrospective case series of patients operated on for neurolysis of the greater sciatic nerve between March 2009 and June 2018 was analyzed. Preoperative and postoperative pain were evaluated using the visual analog scale (VAS) and the Likert scale. The type of postoperative pain was evaluated using the DN4 questionnaire, and the health-related quality of life was measured with the SF-36 questionnaire. Results: Eight patients were included. All patients evolved with a notable improvement in pain, with an average of 3 and 1.88 points on the VAS and Likert scales, respectively. The mean follow-up was 32 months (range 14­66). The DN4 questionnaire showed an average of 3.75 points (range 2­7). According to the SF-36, "Physical Health" was the variable with the worst results, with an average of 30.15. Conclusions: Sciatic nerve neurolysis in patients with neuropathic pain due to sciatic nerve injury and poor response to conservative treatment may improve pain and quality of life.

Transferencia tendinosa del primer radial externo al cubital posterior: ¿mejora significativamente la corrección de la desviación radial en la muñeca reumática? / Extensor carpi radialis longus tendon transfer to extensor carpi ulnaris: Does it significantly improve the correction of radial deviation in the rheumatoid wrist?

Introducción: La artritis inflamatoria puede conducir al síndrome de caput ulnae con desviación radial de la muñeca y los meta-carpianos. El tratamiento es la artroplastia de rescate de la articulación radiocubital distal y la reubicación del tendón del extensor cubital del carpo (ECC). Sin embargo, puede ser débil para corregir la desviación. Clayton describió la transferencia del tendón del extensor radial largo del carpo (ERLC) al ECC. El objetivo de este estudio fue comparar la corrección de la desviación radial de los metacarpianos en pacientes operados con transferencia del ERLC al ECC o sin ella. Materiales y Métodos: Estudio de cohorte retrospectiva en pacientes con artritis reumatoide y síndrome de caput ulnae, sometidos a tenoplastia del ECC con ERLC o sin este procedimiento. Se formaron dos grupos: pacientes con transferencia (grupo A) y sin transferencia (grupo B). Se calculó la corrección del ángulo de Clayton comparando las medidas preoperatoria y del último control, y se compararon los resultados. Resultados: El seguimiento promedio fue de 28 meses. El ángulo de Clayton preoperatorio promedio era de 44,54° (DE ± 7,52) en el grupo A y 60,24° (DE ± 12,28) en el grupo B (p = 0,001). El promedio de corrección fue de 6,57° (DE ± 4,11) y 0,95° (DE ± 9,17), respectivamente (p = 0,026). Conclusiones: El nivel de corrección fue mayor en el grupo A. No obstante, si bien ambas técnicas lograron mejorar el ángulo, el grado de corrección podría estar supeditado a la magnitud del ángulo preoperatorio. Nivel de Evidencia: IV

Introduction: Inflammatory arthritis can lead to caput ulnae syndrome with radial deviation of the wrist and metacarpals. Treatment includes salvage arthroplasty of the distal radioulnar joint and relocation of the extensor carpi ulnaris (ECU) tendon. However, the ECU may be too weak to correct the deviation. To strengthen the ECU, Clayton described the transfer of the extensor carpi radialis longus (ECRL) tendon to the ECU. The aim of this work is to compare the correction of the radial deviation of the metacarpals in patients with and without transfer of the ECRL to the ECU. Materials and Methods: Retrospective cohort study. Patients with rheumatoid arthritis and caput ulnae syndrome, treated with ECU tenoplasty with or without ECRL, were included. The patients were divided into two groups: ECRL to ECU transfer (group A) and no transfer (Group B). The correction of the metacarpal-radial angle (Clayton's angle) was calculated by comparing the measurements before surgery and at end of follow-up, and the results obtained were compared. Results: The average follow-up was 28 months. The preoperative Clayton angle was on average 44.54° (SD ± 7.52) in group A and 60.24° (SD ± 12.28) in group B (p = 0.001). The correction average was 6.57° (SD ± 4.11) and 0.95° (SD ± 9.17) for group A and B respectively (p=0.026). Conclusions: The level of correction obtained was higher in group A. However, although both techniques managed to improve the angle, the degree of correction could be subject to the magnitude of the preoperative angle. Level of Evidence: IV

Short-term complication rate following orthopedic surgery in a tertiary care center in Argentina.

INTRODUCTION: Registration of adverse events following orthopedic surgery has a critical role in patient safety and has received increasing attention. The purpose of this study was to determine the prevalence and severity of postoperative complications in the department of orthopedic unit in a tertiary hospital. METHODS: A retrospective review from the postoperative complication registry of a cohort of consecutive patients operated in the department of orthopedic surgery from May 2015 to June 2016 was performed. Short-term complications (3 months after surgery), age gender, types of surgery (elective, scheduled urgency, non-scheduled urgency, and emergency), operative time, surgical start time (morning, afternoon or evening), American Society of Anesthesiologists score and surgeon's experience were assessed. Complications were classified based on their severity according to Dindo-Clavien system: Grade I complications do not require alterations in the postoperative course or additional treatment; Grade II complications require pharmacological treatment; Grade III require surgical, endoscopic, or radiological interventions without (IIIa) or with (IIIb) general anesthesia; Grade IV are life-threatening with single (IVa) or multi-organ (IVb) dysfunction(s), and require ICU management; and Grade V result in death of the patient. Complications were further classified in minor (Dindo I, II, IIIa) and major (Dindo IIIb, IVa, IVb and V), according to clinical severity. RESULTS: 1960 surgeries were performed. The overall 90-day complication rate was 12.7% (249/1960). Twenty-three complications (9.2 %) were type I, 159 (63.8%) type II, 9 (3.6%) type IIIa, 42 (16.8%) type IIIb, 7 (2.8%) type IVa and 9 (3.6%) were grade V according to Dindo-Clavien classification (DCC). The most frequent complication was anemia that required blood transfusion (27%) followed by wound infection (15.6%) and urinary tract infection (6%). DISCUSSION: The overall complication rate after orthopedic surgery in our department was 12.7%. The implementation of the DCC following orthopedic surgery was an important tool to measure the standard of care.

Combined Tenodesis-Capsulodesis for Scapholunate Instability: Minimum 2-Year Follow-Up.

Background The aim of this study is to evaluate the clinical and radiological midterm results of a combined dorsal tenodesis-capsulodesis for static and reducible scapholunate dissociation (SLD). Patients and Methods We evaluated 20 of 22 consecutive patients with static SLD minimum with follow-up of 2 years operated between 2003 and 2012. The mean age was 40 years (range: 23-65 years). Seventeen were men. Final evaluation included comparative wrist range of motion (ROM) and grip strength, pre- and postoperative pain and function by visual analog scale, and QuickDASH and Wrightington scores. Radiographs included preoperative, early postoperative, and final X-rays. Scapholunate space (SLS) and scapholunate and radioscaphoid angles (SLA and RSA) were measured. Statistical significance was evaluated with Student t-test, considered significant when p < 0.05. Results Mean follow-up was 67 months (range: 24-126 months). Mean final ROM was: flexion 55 degrees (73%), extension 62 degrees (90%), radial deviation 19 degrees (82%), and ulnar deviation 44 degrees (90%). Mean grip strength was 44 kg (92%). Pain at rest improved from 3.4 to 0.5 (p < 0.05). Pain in activity improved from 7 to 1.7 (p < 0.05). Final function was 8.5 (preoperative, 5.2; p < 0.05). Mean QuickDASH score improved from 38 to 8 (p < 0.05). Functional Wrightington score was as follows: 13 excellent, 3 good, 1 regular, and 3 poor. There were three postoperative minor complications. Radiological results (preoperative/early postoperative/final follow-up) were as follows: SLS, 4.7/1.6/1.8 mm; and SLA, 60/50/62 degrees; RSA, 39/45/37 degrees. Four patients showed arthritic changes (two SLAC wrist). Conclusion The clinical and radiological results with more than 2-year follow-up suggest that this technique may be effective, reproducible, and safe for symptomatic static and reducible SLD. Level of Evidence Level IV, case series.

Patient-Rated Wrist Evaluation: Spanish Version and Evaluation of Its Psychometric Properties in Patients with Acute Distal Radius Fracture.

Purpose The purpose of this paper is to validate a Spanish version of patient-rated wrist evaluation (PRWE) and evaluate its psychometric attributes in a population of patients with distal radius fracture. Material and Methods A translation and cross-cultural adaptation of the PRWE to Spanish (PRWE-S) was performed according to standardized guidelines. A total of 50 patients with a distal radius fracture were included during the different steps of the study. The reliability of the new instrument was assessed in terms of construct validity with the Quick DASH (Disability of the Arm, Shoulder, and Hand). Internal consistency and test-retest stability were also examined. Results The Spearman's correlation test for analysis of the criterion validity (0.75) indicates a strong positive correlation between the PRWE-S and the Quick DASH. The internal consistency according to Cronbach's α was 0.96, and the intraclass correlation coefficient was moderate (0.46). Conclusion A Spanish version of the PRWE indicated good validity and reliability in distal radius fracture patients. This valuable tool can be used in Spanish-speaking countries to evaluate various aspects as pain and function in patients with injuries of the wrist.

Volar Plate Fixation in Patients Older Than 70 Years with AO Type C Distal Radial Fractures: Clinical and Radiologic Outcomes.

Introduction Treatment of unstable distal radial fractures (DRFs) in elderly patients is controversial, and considering the increasing life expectancy, their appropriate treatment is of growing importance. Our aim was to analyze the clinical and radiologic outcomes in the elderly patients with AO type C DRF treated with volar locking plate (VLP). Materials and Methods Between 2007 and 2011, 572 DRFs were operated on in our hospital with open reduction and internal fixation with VLP. Of these, only 64 patients (66 DRFs) met the selection criteria (AO type C DRF, age > 70 years, minimum 12-month follow-up). Mean follow-up was 28 months. Outcome assessment included range of motion, grip strength, VAS pain, Mayo Clinic Score, and DASH score. Analysis of pre- and postoperative radiographs was performed. Complications were recorded. Statistical analysis was performed comparing the results with the contralateral side. Results Mean postoperative range of motion of the injured wrist compared with the control contralateral side was 86% for flexion ( p < 0.001), 92% for extension ( p < 0.001). The average DASH was 12. Mayo Clinic Wrist Score showed 43 excellent results, 15 good, 4 satisfactory, and 4 poor. Articular step-offs were reduced in 34 of 38 wrists. Five (7%) patients required plate removal. Conclusion The treatment of articular DRF (AO type C) with VLP in the elderly patients achieved greater than 90% of the wrist range of motion and grip strength with no residual pain in greater than 90% of the patients.

Osteotomía en cuña sustractiva supracondílea para el tratamiento del codo valgo del adulto / Supracondylar subtraction wedge osteotomy for the treatment of adult cubitus valgus

Objetivo: Comunicar los resultados de una serie de adultos con consolidaciones en valgo del codo tratados con una osteotomía en cuña sustractiva monoplanar. materiales y métodos: Se incluyeron 5 pacientes. Se describe la técnica quirúrgica que consistió en un abordaje posterior paratricipital, resección en cuña sustractiva y transposición anterior del nervio cubital. El seguimiento promedio fue de 17 meses. Resultados: Se trató a 4 hombres y una mujer, con una edad promedio de 27 años. La movilidad preoperatoria promedio fue de 138-7° y la posoperatoria, de 138-6°, el puntaje de dolor en la EAV fue de 4 y 1, el MEPS de 71 y 97, y el DASH de 26 y 8, respectivamente. La evaluación radiográfica preoperatoria arrojó un valgo promedio de 30° con un valgo contralateral de 11°. La corrección radiográfica demostró un valgo de 13°. Se obtuvo una corrección promedio de 2° menos que del otro lado. Todas las osteotomías consolidaron, y la medición de la prominencia medial fue, en promedio, un 32% mayor que en el preoperatorio. Según la escala de Oppenheim, el resultado fue excelente en 4 pacientes y bueno en uno. La satisfacción personal fue, en promedio, de 8,6. Conclusiones: La osteotomía en cuña sustractiva para tratar un codo valgo es una buena opción terapéutica, con recuperación de valores angulares comparables con el lado contralateral, y alta tasa de satisfacción de los pacientes. Como es una técnica menos compleja que las osteotomías multiplanares, es nuestra elección ante una consolidación viciosa en valgo del codo del adulto. Nivel de Evidencia: IV

Objective: To report the results of a series of adult patients with a valgus malunion of the elbow treated with a supracondylar subtractive monoplanar wedge osteotomy, materials and methods: 5 patients were included. The surgical technique consisted of a posterior paratricipital approach, with resection of a subtractive wedge and the anterior transposition of the ulnar nerve. The average follow-up was 17 months.Results: 4 patients were men and 1 woman with an average age of 27 years. The preoperative range of motion was 138°-7° and the postoperative range of motion was 138-6°. Pain according to VAS was 4 and 1, MEPS was 71 and 97, and DASH was 26 and 8, respectively. The preoperative radiological evaluation showed an average valgus of 30° with a contralateral valgus of 11º. The final valgus obtained was 13°. The final correction was, on average, 2° less than the contralateral side. All osteotomies healed and the medial prominence was on average 32%, more than before surgery. According to Oppenheim scale, the results were excellent in 4 patients and good in 1. Personal satisfaction was, on average, 8.6. Conclusions: Supracondylar subtractive wedge osteotomy is a good option for the treatment of adult cubitus valgus with a recovery of angular values similar to the contralateral side and a high satisfaction rate. As it is a simpler technique, compared to the multiplanar osteotomies, it is our treatment of choice for adult cubitus valgus. Level of Evidence: IV

Prótesis total de codo en el contexto de una seudoartrosis de olécranon. Técnica quirúrgica y reporte de tres casos / Total elbow arthroplasty in the context of a nonunion of the olecranon. Surgical technique and report of 3 cases

La indemnidad del aparato extensor es fundamental para un correcto funcionamiento de una prótesis de codo. Se ha considerado que la deficiencia del tríceps es una contraindicación relativa para la artroplastia, porque produce una contractura en flexión y un déficit de extensión activa. Estas limitaciones pueden afectar significativamente la mejora funcional que la artroplastia total de codo produce. Ante una seudoartrosis de olécranon, la colocación de una prótesis total de codo se presenta como un problema complejo que resolver. El objetivo de este artículo es describir la técnica quirúrgica para la colocación de una prótesis total de codo en el contexto de una seudoartrosis de olécranon, y comunicar tres casos. Nivel de Evidencia: IV

The integrity of the extensor apparatus is essential for the correct functioning of an elbow prosthesis. Triceps deficiency has been considered a relative contraindication for arthroplasty, because it produces a flexion contracture and an active extension deficit. These limitations can significantly affect the functional improvement that total elbow arthroplasty produces. Faced with an olec-ranon nonunion, the placement of a total elbow prosthesis is presented as a complex problem to be solved. The objective of this article is to describe the surgical technique for the placement of a total elbow prosthesis in the context of an olecranon nonunion, and to report three cases.

Artroplastia total de codo después de un proceso infeccioso. Cirugía en dos tiempos / Total elbow arthroplasty after an infection process. Two-stage surgery

Objetivo: Comunicar los resultados en pacientes con un proceso infeccioso del codo, tratados en 2 etapas quirúrgicas: la primera con un espaciador de cemento con antibiótico y la segunda con una artroplastia total de codo. materiales y métodos: Se descri-ben los criterios de inclusión, el diagnóstico de infección y las 2 etapas quirúrgicas. Resultados: Se incluyeron 10 pacientes (4 hombres y 6 mujeres, edad promedio 62 años). Causas iniciales: degenerativas (2 casos) y traumáticas (8 casos). Se realizaron 4 aloprótesis y 2 colgajos de dorsal ancho. Se identificaron 2 grupos: A (defectos óseos <4 cm) y B (>4 cm). El seguimiento fue de 5 años. La flexo-extensión fue de 117°/29° en el preoperatorio y 130°/29° en el posoperatorio; los puntajes de dolor fueron 6,5 y 2,5 (EAV); 40 y 80 (MEPS); y 56 y 30 (DASH), respectivamente. La fuerza de extensión fue de M5 (4 casos), M4 (2 casos), M3 (1 caso), M1 (2 casos) y M0 (1 caso). Un paciente tuvo una necrosis del colgajo que evolucionó con infección y 9 no tenían infección al final del seguimiento. Los pacientes del grupo A tenían menos cirugías previas y mejores resultados funcionales. Conclusiones: El tratamiento de un proceso infeccioso de codo mediante un espaciador de cemento con antibiótico permite controlar la infección en un alto porcentaje de los casos. La reconstrucción protésica secundaria es demandante y se asocia a complicaciones. Cabe esperar que, cuanto más grande sea el defecto óseo y mayor la cantidad de procedimientos previos, los resultados funcionales sean peores. Nivel de Evidencia: IV

Objective: to report the results of patients with an infectious elbow process, treated in 2 surgical stages: the first with an antibiotic cement spacer (ACE) and the second with a total elbow arthroplasty. Material and methods: the inclusion criteria, the diagnosis of infection and the 2 surgical stages are described. Results: 10 patients were included (7 men and 3 women), average age: 62 years old. Initial causes: degenerative in 2 cases and traumatic in 8. 4 alloprostheses and 2 latissimus dorsi flaps were performed.Follow-up was 5 years. Flexo-extension was 117°/29° in preoperative and 130°/29° in postoperative; pain according to EVA: 6.5 and 2.5; MEPS: 40 and 80; DASH 56 and 30 respectively. The extension force was M5 (4 cases), M4 (2), M3 (1), M1 (2) and M0 (1). One patient presented a necrosis of the flap that evolved with infection. In 9 of the 10 cases the patients were free of infection at the end of the follow-up. Two groups of patients were identified: Group A (bone defects less than 4 cm) and B (more than 4 cm). Group A patients had fewer previous surgeries and better functional outcomes. Conclusion: the treatment of an infectious elbow process through the placement of antibiotic cement spacer, allows a control of the infection in a high percentage of cases. Secondary prosthetic reconstruction is demanding and associated with complications. It is to be expected that the greater the bone defect and the greater the number of previous procedures, result in the worse the functional results. Level of Evidence: IV
