Two Cases of Anterior Shoulder Dislocation and Fracture Secondary to Generalized Tonic-Clonic Seizure.

Dislocation of the glenohumeral joint secondary to generalized tonic-clonic seizures is well documented in the medical literature, with posterior dislocation being most commonly described. Still, these occurrences tend to be rare and affect a minority of patients, and fractures associated with dislocations after seizures are even less common. As such, the management of these injuries tends to be quite varied, and there is a paucity of documented cases in the literature. Here, we would like to present two rare cases of anterior shoulder dislocation secondary to seizures, with one patient also sustaining a fracture of the proximal humerus. We would also like to discuss the management and outcomes that have been achieved, since these cases tend to occur in a small number of epileptic patients.

Extensor Mechanism Ruptures and Reruptures: Perioperative Opioid Management.

The purpose of this study was to determine (1) the correlation between preoperative and postoperative opioid use and (2) risk factors associated with rerupture in patients undergoing open extensor mechanism repair. A retrospective review of patients who underwent operative repair of quadriceps or patellar tendon rupture was performed. Patients were classified as opioid nonusers if they had not received any opioid medications in the 3 months before surgery, or as acute users or chronic users if they received at least one opioid prescription within 1 month or 3 months preceding surgery. Clinical records were reviewed for postoperative opioid use within a year after surgery as well as rerupture rates. A total of 144 quadriceps tendon and 15 patellar tendon repairs were performed at a mean age of 56.8 ± 15.1 years and body mass index of 33.2 ± 7.1. The overall rerupture rate was 6%. Diabetes was a significant risk factor for rerupture (56 vs. 19%, p = 0.023). Chronic preoperative opioid users were more likely to continue to use opioids beyond 1 month postoperatively (p < 0.001) as compared with acute or nonopioid users. Chronic preoperative opioid users (relative risk [RR]: 3.53, 95% confidence interval [CI]: 2.11-5.90) and patients with longer anesthesia time (RR: 1.39, 95% CI: 1.00-1.93) required more monthly opioid refills, whereas tourniquet use required fewer opioid refills each month (RR: 0.57, 95% CI: 0.37-0.88). Compared with patients without a rerupture, each additional prescription refill after the initial repair in the rerupture group was associated with a 22% higher risk of tendon rerupture (RR: 1.22, 95% CI: 1.07-1.39). The chronicity of preoperative opioid intake was found to have a significant effect on postoperative opioid use. This study suggests that there is a higher prevalence of rerupture in patients with prolonged opioid use postoperatively and among diabetics.

Comparison of Tendon Lengthening With Traditional Versus Accelerated Rehabilitation After Achilles Tendon Repair: A Prospective Randomized Controlled Trial.

BACKGROUND: Early weightbearing protocols after Achilles tendon repair promote mobilization, yet little is known about their effect on tendon lengthening. PURPOSE: To evaluate tendon lengthening after Achilles tendon repair with accelerated rehabilitation. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Patients undergoing primary repair for acute Achilles tendon ruptures consented to have tantalum beads placed within the tendon. Patients were randomized into either a traditional (weightbearing at 6 weeks) or accelerated (graduated weightbearing at 2 weeks) rehabilitation group. The primary outcome of the study was postoperative tendon elongation as measured by radiostereometric beads. Secondary outcomes included Achilles Tendon Total Rupture Score (ATRS) and Patient-Reported Outcomes Measurement Information System Pain Interference Short Form (PROMIS PI-SF) score. RESULTS: All 18 patients included in the final analysis were found to have significant tendon lengthening after surgery, with a mean lengthening of 15.9 mm. No significant differences were found in overall lengthening between the traditional and accelerated rehabilitation groups (15.3 ± 4.5 vs 16.4 ± 4.7 mm, respectively; P = .33) at final follow-up. The repair site in each group was found to lengthen more than the intratendinous site (traditional group, 13.2 vs 2.1 mm; accelerated group, 16.8 vs -0.4 mm); however, no difference in lengthening was seen between groups (P = .82 and P = .31, respectively). The greatest amount of lengthening occurred between 2 and 6 weeks, and the least amount of lengthening occurred between 6 and 12 weeks, with no difference between the traditional and accelerated groups at these time points (P = .84 and P = .38, respectively). No differences were noted in ankle range of motion (dorsiflexion, P = .16; plantarflexion, P = .08) or outcome scores (ATRS, P = .56; PROMIS PI-SF, P = .54). CONCLUSION: This study's findings demonstrate that all patients undergoing operative repair of Achilles tendon ruptures had lengthening after surgery. No difference was found in tendon lengthening (repair site or intratendinous) at any time point between patients undergoing traditional versus accelerated rehabilitation postoperatively. The greatest amount of lengthening was found to occur between 2 and 6 weeks postoperatively, and tendon lengthening decreased significantly after 6 weeks.

Ten- and 20-year Survivorship of the Hip After Periacetabular Osteotomy for Acetabular Dysplasia.

INTRODUCTION: Acetabular dysplasia is a multifactorial condition characterized by a shallow hip socket with predisposition to osteoarthritis of the hip. The Bernese periacetabular osteotomy (PAO), developed by Reinhold Ganz in 1984, reorients the dysplastic hip joint to provide more uniform coverage of the femoral head and to extend the longevity of the native hip. Since 1987, the senior author performed the Bernese PAO on more than 430 patients. We performed a cross-sectional retrospective study on this cohort of patients to determine the 10- and 20-year survivorship after PAO in addition to assessing functional outcomes and radiographic parameters. METHODS: Four hundred thirty-four patients were treated for acetabular dysplasia with PAO by the senior surgeon from 1987 to 2014. Data were obtained for 302 hips in 258 patients in a retrospective fashion from medical records and/or mail-in/phone questionnaires. Functional outcome data consisted of postoperative Hip Osteoarthritis Outcome Score and University of California-Los Angeles Activity Score. Pre- and postoperative radiographs were used to determine lateral center-edge angle, anterior center-edge angle, Tönnis angle/grade, and head-to-ilioischial line distance. Survivorship of the native hip was determined by Kaplan-Meier analysis. RESULTS: Of the 302 hips analyzed, 248 were still surviving native hips and 54 had gone on to a total hip arthroplasty (THA) at the time of data acquisition. The average age of patients in the entire cohort at PAO was 32.7 years (range, 13 to 63 years). Of the 258 patients, 215 were female patients (83.3%) and 43 male patients (16.8%). The average age of patients in the surviving group at PAO was 32.3 years, and the average age of patients in the THA group was 36.6 years (P < 0.01). At the time of data acquisition, follow-up ranged from 2 to 27 years (average, 11.2 years). Hip Osteoarthritis Outcome Score and University of California-Los Angeles Activity Score are reported for the surviving native hips after PAO. Radiographic analyses for surviving and failed hips are described, with pre- and postoperative Tönnis grade being statistically significant predictors for conversion to THA (P < 0.01). Survivorship of the native hip was 86% at 10 years and 60% at 20 years in the surviving cohort. Survivorship stratified by age at the time of PAO demonstrated a 10-year survivorship of 93.3%, 90.1%, 81.6%, and 63.2% at ages 20, 30, 40, and 50 years, respectively. No notable difference exists in survivorship between male and female patients; however, male patients had a trend toward lower survivorship compared with female patients at 15 years. CONCLUSION: The 10- and 20-year survivorship of the native hip after PAO is approximately 86% and 60%, respectively, in our cohort of 302 hips. Older age at the time of PAO and higher Tönnis grade are negative prognostic factors for joint survival after PAO. Surviving hips after PAO have good functional outcomes even up to 20 years after surgery. This survivorship analysis represents one of the largest and longest survival studies of patients after PAO, and our results are consistent with other published studies. LEVEL OF EVIDENCE: Level III.
