Return to Sports After Plate Fixation of Displaced Midshaft Clavicular Fractures in Athletes

Background: Recent prospective randomized trials support primary plate fixation of displaced midshaft clavicle fractures. However, the safety and efficacy of this practice have not been well documented in athletes, nor has the time to return-to-sport. Purpose: To analyze the time to return-to-sport, functional outcomes, and complications in a group of athletes with displaced midshaft clavicle fractures treated using precontoured locking plates. Study Design: Case series; Level of evidence, 4. Methods: A total of 54 athletes with displaced midshaft clavicle fractures were treated with plate fixation between November 1, 2008, and December 31, 2012. The mean follow-up time was 22.4 months. Patients completed a questionnaire focused on the time to return-to-sport and treatment course. Functional outcomes were assessed with the Constant score and short version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. Pain was evaluated with the visual analog scale (VAS). Radiographs were reviewed to identify radiographic union time, malunion, and nonunion. Results: Of the 54 patients, 53 returned to sports after open reduction and internal fixation of their fracture; 94% returned to the same level. The mean time to return-to-sport was 68 days (range, 5-180 days). Nine (16.6%) of the cases returned to sports before 6 weeks after surgery, 40 (74%) returned between 6 and 12 weeks, and 5 patients (9.2%) returned 12 weeks after surgery. The mean Constant score was 94.1 ± 5.2 (range, 78-100), and the mean QuickDASH score was 0.4 ± 4.7 (range, 0-7.1). The mean VAS pain score during follow-up was 0.29 ± 1.0 (range, 0-5). Three major complications occurred: 1 extrinsic compression of the subclavian vein, 1 nonunion, and 1 hardware loosening. Hardware removal was necessary in 5 patients (9.3%). Conclusion: Plate fixation of displaced clavicle fractures in athletes is a safe procedure resulting in excellent functional outcomes, with an early return to the same level of sports in the majority of patients.

Hip arthroscopy in osteoarthritis: a systematic review of the literature.

Background Hip arthroscopy treatment in patients with osteoarthritis is controversial. Hypothesis/Purpose To systematically review the clinical outcome of patients with hip osteoarthritis (OA) treated with arthroscopy and what proportion of these patients subsequently underwent total hip arthroplasty (THA). Study design Systematic review. Methods PubMed, Cochrane library and LILACS were searched from January 1990 through December 2013 for eligible studies. The methodological quality of the collected data (applied to each study) was performed with a modified version of the Coleman methodology score (mCMS). Results 11 studies were included in this review. Most of the studies included reported clinical improvements. The overall conversion rate to THA ranged from 9.5% to 50%. Mean time between arthroscopy and THA was 13.5 months. Conclusions The quality of studies is low. We have found inconclusive evidence to make categorical indications for hip arthroscopy in the treatment of OA, although we have found that there is some postoperative clinical outcome improvement of pain and function in a short-term evaluation. Increasingly worse outcomes were seen as the severity of OA increased.

Modified Latarjet Without Capsulolabral Repair in Rugby Players With Recurrent Anterior Glenohumeral Instability and Significant Glenoid Bone Loss

Background: The optimal management of recurrent anterior shoulder instability with significant glenoid bone loss in high-demand collision athletes remains a challenge. Purpose: To analyze the time to return to sport, clinical outcomes, and recurrences following a modified Latarjet procedure without capsulolabral repair in rugby players with recurrent anterior shoulder instability and significant glenoid bone loss. Study Design: Case series; Level of evidence, 4. Methods: Between June 2008 and June 2015, 50 competitive rugby players (practice >2 times per week and competition during weekends) with recurrent anterior shoulder instability underwent operation with the modified congruent arc Latarjet procedure without capsulolabral repair in our institution. Cases included 18 primary repairs and 32 revisions. Return to sports, range of motion (ROM), the Rowe score, a visual analog scale for pain in sport activity (VAS), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Recurrences were also evaluated. The postoperative bone block position and consolidation were assessed with computed tomography. The final analysis included 49 shoulders in 48 patients (31 revision cases). Results: The mean follow-up was 48 months (range, 24-108 months) and the mean age at the time of operation was 22.8 years (range, 17-35 years). Forty-five patients (93.7%) returned to playing rugby, all at their preinjury level of play. No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe, VAS, and ASOSS scores showed statistically significant improvement after operation (P < .001). The Rowe score increased from a mean of 39.5 points preoperatively to 94 points postoperatively (P < .01). The VAS score decreased from 3.6 points preoperatively to 1.2 points postoperatively (P < .01). The ASOSS score improved significantly from a mean of 44 points preoperatively to 89.5 points postoperatively (P < .01). No recurrence of shoulder dislocation or subluxation was noted. The bone block healed in 43 shoulders (88%). Conclusion: In rugby players with recurrent anterior shoulder instability and significant glenoid bone loss, the modified Latarjet procedure without capsulolabral repair produced excellent functional outcomes, with most athletes returning to rugby at their preinjury level of play without recurrences.

Corrective osteotomy for malunion of proximal humerus using a custom-made surgical guide based on three-dimensional computer planning: case report

Malunion after a proximal humerus fracture is a potential complication independent of the selected treatment. This situation is commonly well tolerated in the elderly and low-demand populations; however, young, active patients may develop persistent dysfunction and pain. Surgical intervention may improve the quality of life in these patients. In complex malunion patterns, multiplanar osteotomy is a highly demanding procedure that requires detailed preoperative planning. Computer-assisted planning and patientspecific instrumentation (PSI) for corrective osteotomies have gained popularity in orthopedic surgery, becoming a useful tool for analysis of the deformity and preoperative planning. We report the clinical and radiographic results of a proximal humerus malunion treated with a multiplanar osteotomy using PSI based on preoperative 3-dimensional (3D) planning. We describe in detail the preoperative planning and surgical procedure.

Retorno al deporte posterior a una reconstrucción simultánea de ligamento cruzado anterior y ligamento colateral medial de grado III en periodo subagudo

RESUMEN Introducción: las lesiones asociadas del ligamento cruzado anterior (LCA) y del ligamento colateral medial (LCM) corresponden al 20% de la lesiones ligamentosas de la rodilla. El tratamiento conservador del LCM y la reconstrucción quirúrgica del LCA son generalmente recomendados. En deportistas, el tratamiento conservador del LCM puede conducir a inestabilidad medial crónica. El manejo óptimo de deportistas con lesiones combinadas de LCA-LCM continúa siendo controvertido. El objetivo de este trabajo es analizar los resultados funcionales y el nivel deportivo alcanzado en el postoperatorio de una serie de pacientes tratados con reconstrucción simultanea de LCA y LCM con un seguimiento mínimo de 2 años. Material y métodos: un total de 20 atletas con reconstrucciones agudas simultáneas de LCA y LCM de grado III fueron tratados entre marzo de 2006 y enero de 2014. El tiempo mínimo de seguimiento fue de 24 meses. Se evaluaron los resultados funcionales subjetivos (International Knee Documentation Committee –IKDC–, Lysholm), rango de movilidad, estabilidad anteromedial y rotacional (Lachmann, pivot shift, estrés valgo). Se registró la capacidad de retorno al deporte (Tegner) y el nivel alcanzado. ABSTRACT Return to sports after sub-acute simultaneous reconstruction of anterior cruciate ligament injury and grade III medial collateral ligament injury

Modified Latarjet Procedure Without Capsulolabral Repair for Failed Previous Operative Stabilizations

The optimal management of recurrent anterior shoulder instability with significant glenoid bone loss continues to be a challenge. The high recurrence rates seen in arthroscopic Bankart repair in the presence of significant glenoid bone loss have led many surgeons to choose bony reconstructions to manage these injuries. The Latarjet procedure acts through the combination of 3 different mechanisms: the coracoid bone graft restores and extends the glenoid articular arc, the conjoint tendon acts as a dynamic sling on the inferior subscapularis and anteroinferior capsule when the arm is abducted and externally rotated, and the effect of repairing the capsule to the stump of the coracoacromial ligament. However, in patients with multiple recurrences and previous surgeries, the anteroinferior labrum and capsule are often very deficient or practically destroyed. This Technical Note provides a detailed description of the modified Latarjet procedure without capsulolabral repair for patients with failed previous operative stabilizations.

Return to Sports after Acute Simultaneous Reconstruction of Anterior Cruciate Ligament Injury and Grade III Medial Collateral Ligament Injury

Objectives: Combined Anterior Cruciate Ligament (ACL) injury and Medial Collateral Ligament (MCL) injury account for 20% of knee ligament lesions. Conservative treatment of MCL and surgical ACL reconstruction are generally recommended. Significant medial instability after non-surgical management of MCL can lead to ACL reconstruction failure. The optimal management for athletes with combined ACL-MCL injuries remains controversial. The purpose of this study was to analyze the functional and clinical evolution of patients who underwent combined ACL-MCL surgery and their return-to-sport level with minimum 2-years follow-up. Methods: A total of 20 athletes with acute simultaneous ACL/Grade III MCL reconstructions were treated between March 2006 and January 2014. The minimum follow-up time was 24 months. Subjective functional results (IKDC, Lysholm), range of motion, anterior-medial and rotational stability (Lachmann, Pivot Shift, valgus stress) were evaluated. The ability to return to sport (Tegner) and the level achieved was recorded. Results: All patients significantly improved functional scores and stability tests. The mean subjective IKDC score improved from 37.7 ± 12.9 (range 21-69) preoperatively to 88.21 ± 4.47 (range 80-96) postoperatively (P <0.05). The average Lysholm score was 40.44 ± 10.58 (range 27-65) preoperatively and 90.83 ± 3.38 (range 84-95) postoperatively (P <0.05). Valgus and sagittal laxity was not observed (IKDC A 92% B 8%) at final follow-up. All patients had normal/nearly normal (IKDC A or B) mobility. All patients returned to sports; 90% reached the level they had prior to the ligamentous injury. Of all competitive athletes, 66% achieved the same level of sport. Conclusion: In athletes with acute ACL-Grade III MCL lesions, an early simultaneous reconstruction can significantly improve the medial and sagittal stability of the knee. This procedure resulted in excellent functional outcomes, with return to the same level of sports in the majority of patients at short-term follow-up.

Return to Sports and Recurrences After Arthroscopic Anterior Shoulder Stabilization in Martial Arts Athletes

Background: The high demands to the glenohumeral joint and the violent shoulder blows experienced during martial arts (MA) could compromise return to sports and increase the recurrence rate after arthroscopic stabilization for anterior shoulder instability in these athletes. Purpose: To report the functional outcomes, return to sports, and recurrences in a series of MA athletes with anterior shoulder instability treated with arthroscopic stabilization with suture anchors. Study Design: Case series; Level of evidence, 4. Methods: A total of 20 consecutive MA athletes were treated for anterior shoulder instability at a single institution between January 2008 and December 2013. Range of motion (ROM), the Rowe score, a visual analog scale (VAS), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Return-to-sport and recurrence rates were also evaluated. Results: The mean age at the time of surgery was 25.4 years (range, 18-35 years), and the mean follow-up was 71 months (range, 36-96 months). No significant difference in preoperative and postoperative shoulder ROM was found. The Rowe, VAS, and ASOSS scores showed statistical improvement after surgery (P < .001). In all, 19 athletes (95%) returned to sports. However, only 60% achieved ≥90% recovery after surgery. The recurrence rate was 20%. Conclusion: In this retrospective study of a consecutive cohort of MA athletes, arthroscopic anterior shoulder stabilization significantly improved functional scores. However, only 60% of the athletes achieved the same level of competition, and there was a 20% recurrence rate.
