Displaced medial clavicle fractures: a systematic review of outcomes after nonoperative and operative management.

Background: Fractures of the medial clavicle are uncommon. There is no consensus regarding the optimal treatment of displaced medial clavicle fractures. Methods: A systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed. PubMed, EMBASE, and the Cochrane Library were queried using the terms medial clavicle and fracture to identify all studies reporting on outcomes following either nonoperative or operative treatment of displaced medial clavicle fractures. Data extracted included patient demographics, fracture classification, surgical technique, patient-reported outcomes, physical, and radiographic findings. Study quality was evaluated using the Methodological Index for Non-Randomized Studies (MINORS) scoring system. Results: The analysis included 15 studies (mean MINORS score, 10 ± 1.5) with a total of 135 patients (85% male, mean age 47 ± 10.9 years [range, 15-87 years]). Five studies (39 patients) reported outcomes following nonoperative treatment. At a mean follow-up of 27 months, there were 5 (13%) symptomatic nonunions, 2 (5%) malunions, and 2 (5%) delayed unions. Eleven studies (96 patients) reported outcomes following surgical treatment with a mean follow-up of 23 months. There were no reported nonunions. Complications included plate prominence/ irritation (30%) and additional surgery was performed for plate removal (27%), fixation failure (3%), and wound débridement (1%). Conclusion: There is limited, low-quality evidence in the literature to guide treatment of displaced medial clavicle fractures. The available data suggest that surgical treatment is associated with good functional outcomes and a lower risk of nonunion and malunion, compared to nonoperative treatment but plate irritation and further surgery to remove the plate was common.

Management of glenoid bone loss in primary reverse shoulder arthroplasty : a systematic review and meta-analysis.

AIMS: Rates of reverse total shoulder arthroplasty (rTSA) continue to grow. Glenoid bone loss and deformity remains a technical challenge to the surgeon and may reduce improvements in patients' outcomes. However, there is no consensus as to the optimal surgical technique to best reconstruct these patients' anatomy. This review aims to compare the outcomes of glenoid bone grafting versus augmented glenoid prostheses in the management of glenoid bone loss in primary reverse total shoulder arthroplasty. METHODS: This systematic review and meta-analysis evaluated study-level data in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. We performed searches of Medline (Ovid), Embase (Ovid), and PubMed from their dates of inception to January 2022. From included studies, we analyzed data for preoperative and postoperative range of motion (ROM), patient-reported functional outcomes, and complication rates. RESULTS: A total of 13 studies (919 shoulders) were included in the analysis. The mean age of patients at initial evaluation was 72.2 years (42 to 87), with a mean follow-up time of 40.7 months (24 to 120). Nine studies with 292 rTSAs evaluated the use of bone graft and five studies with 627 rTSAs evaluated the use of augmented glenoid baseplates. One study was analyzed in both groups. Both techniques demonstrated improvement in patient-reported outcome measures and ROM assessment, with augmented prostheses outperforming bone grafting on improvements in the American Shoulder and Elbow Surgeons Score. There was a higher complication rate (8.9% vs 3.5%; p < 0.001) and revision rate among the bone grafting group compared with the patients who were treated with augmented prostheses (2.4% vs 0.6%; p = 0.022). CONCLUSION: This review provides strong evidence that both bone graft and augmented glenoid baseplate techniques to address glenoid bone loss give excellent ROM and functional outcomes in primary rTSA. The use of augmented base plates may confer fewer complications and revisions.Cite this article: Bone Joint J 2022;104-B(12):1334-1342.

Long-Term Trajectories in Weight and Health Outcomes Following Multidisciplinary Publicly Funded Bariatric Surgery in Patients with Clinically Severe Obesity (≥ 3 Associated Comorbidities): A Nine-Year Prospective Cohort Study in Australia.

Background: Real-world data on long-term (> 5 years) weight loss and obesity-related complications after newer bariatric surgical procedures are currently limited. The aim of this longitudinal study was to examine the effectiveness and sustainability of bariatric surgery in a cohort with clinically severe obesity in a multidisciplinary publicly funded service in two teaching hospitals in New South Wales, Australia. Methods: Patients were adults with complex clinically severe obesity with a BMI ≥ 35 kg/m2 and at least three significant obesity-related comorbidities, who underwent bariatric surgeries between 2009 and 2017. Detailed obesity-related health outcomes were reported from annual clinical data and assessments for up to 9 years of follow-up. Data were also linked with the national joint replacement registry. Results: A total of 65 eligible patients were included (mean, 7; range, 3−12 significant obesity-related comorbidities); 53.8% female; age 54.2 ± 11.2 years, with baseline BMI 52.2 ± 12.5 kg/m2 and weight 149.2 ± 45.5 kg. Most underwent laparoscopic sleeve gastrectomy (80.0%), followed by laparoscopic adjustable gastric banding (10.8%) and one anastomosis gastric bypass (9.2%). Substantial weight loss was maintained over 9 years of follow-up (p < 0.001 versus baseline). Significant total weight loss (%TWL ± SE) was observed (13.2 ± 2.3%) following an initial 1-year preoperative intensive lifestyle intervention, and ranged from 26.5 ± 2.3% to 33.0 ± 2.0% between 1 and 8 years following surgery. Type 2 diabetes mellitus (T2DM), osteoarthritis-related joint pain and depression/severe anxiety were the most common metabolic, mechanical and mental health comorbidities, with a baseline prevalence of 81.5%, 75.4% and 55.4%, respectively. Clinically significant composite cumulative rates of remission and improvement occurred in T2DM (50.0−82.0%) and hypertension (73.7−82.9%) across 6 years. Dependence on continuous positive airway pressure treatment in patients with sleep-disordered breathing fell significantly from 63.1% to 41.2% in 6 years. Conclusion: Bariatric surgery using an intensive multidisciplinary approach led to significant long-term weight loss and improvement in obesity-related comorbidities among the population with clinically complex obesity. These findings have important implications in clinical care for the management of the highest severity of obesity and its medical consequences. Major challenges associated with successful outcomes of bariatric surgery in highly complex patients include improving mental health in the long run and reducing postoperative opioid use. Long-term follow-up with a higher volume of patients is needed in publicly funded bariatric surgery services to better monitor patient outcomes, enhance clinical data comparison between services, and improve multidisciplinary care delivery.

How coronal alignment affects distal femoral anatomy: an MRI-based comparison of varus and valgus knees.

PURPOSE: In contemporary total knee arthroplasty (TKA), most often, the goal is to align the femoral component to the epicondylar axis (EA). The posterior condylar axis (PCA) is easier to define than the EA, and thus the relationship of PCA to the EA is then used instead to align the femoral component to the EA. However, the relationship of PCA to EA is not constant and has been reported to differ between varus and valgus knees and with increasing deformity. The aim of this large MRI-based study was to evaluate the relationship between PCA and EA with varying coronal deformity especially with increasing valgus deformity. METHODS: EA, PCA, AP (Whiteside's line) and the mechanical axis were obtained from 474 magnetic resonance imaging (MRI) scans used to create patient-specific instrumentation (PSI) for the Biomet Signature (Warsaw, NJ) system. RESULTS: The relationship of EA relative to the PCA showed considerable heterogeneity in both varus and valgus groups. In the valgus group, there was statistically greater external rotation (P < 0.05) of the EA from the PCA with a mean of 2.52° (range - 1.9° to 6°) compared to the varus group with a mean of 2.03° (range - 3.9° to 6.9°). This relationship did not significantly change with increasing severity of coronal malalignment. Externally rotating the femoral cutting guide by 3° from the PCA, 11% (42 of 382) of varus knees would lie outside of ± 3° from EA. In valgus knees, externally rotating the femoral cutting block by 3° or 5° from the PCA, 6.5% (6 of 92) and 33.7% (31 of 92) of knees, respectively, would lie outside of ± 3° from EA. CONCLUSION: The relationship of PCA to EA is heterogeneous and is not altered significantly with increasing valgus coronal deformity. External rotation beyond 3° from PCA in valgus knees may lead to significant femoral component malrotation in a large proportion cases.

Management of rotator cuff tears in the elderly population.

Rotator cuff tears (RCTs) are a common cause of shoulder pain and weakness in the elderly (age > 65yrs) and result in reduced quality of life, loss of income and a burden on health care. With the elderly population living longer there is a growing interest in the effective and efficient management of RCTs. In a majority of cases, the initial treatment is conservative, with physical therapy, analgesics and possibly corticosteroid or plasma rich protein injections. There are various surgical options, including rotator cuff repair, superior capsule reconstruction, subacromial decompression and reverse shoulder arthroplasty. The aim of this article is to provide a narrative review of evidence guiding the management options for RCTs in the elderly.

Shoulder replacement for osteoarthritis: A review of surgical management.

Osteoarthritis of the shoulder is caused by progressive cartilage wear of the glenohumeral joint. Its prevalence is increasing due to our ageing population and it may affect up to one-third of people over 60 years of age. Patients usually complain of pain with restricted shoulder movement and function. Initial treatment should be non-operative, such as activity modification, oral analgesics (e.g. non-steroidal anti-inflammatories) and possibly physical therapy or corticosteroid injections. Patients with ongoing severe pain and functional restriction despite non-operative treatment would be candidates for surgery, usually a shoulder replacement. There are various forms of shoulder replacements and the aim of this review is to discuss the types available, the indications for using one over another and recent worldwide trends in the use of shoulder replacements.

How Should We Follow-Up Asymptomatic Metal-on-Metal Hip Resurfacing Patients? A Prospective Longitudinal Cohort Study.

Current surveillance for metal-on-metal hip resurfacing (MoMHR) patients is not evidence based. This study established changes that occurred in 152 asymptomatic MoMHRs using repeat ultrasound and patient-reported outcomes. Factors associated with (1) ultrasound progression and (2) developing new pseudotumors were analyzed. Patients underwent repeat assessments 4.3 years later. Ultrasound progression was observed in 19% (n = 29), with 10% (n = 15) developing new pseudotumors. Key predictors of ultrasound progression included high blood cobalt (P = .00013) and chromium (P = .00065), and high initial ultrasound grade (P = .003) and volume (P = .036). No asymptomatic MoMHRs with initially normal metal ions (<2 µg/L) and normal ultrasounds (33% of cohort) developed new pseudotumors. This patient subgroup does not require repeat follow-up within 5 years.

Cerebral oxygenation using near-infrared spectroscopy in the beach-chair position during shoulder arthroscopy under general anesthesia.

PURPOSE: To examine the risks of shoulder arthroscopy in the beach-chair position (BCP) as opposed to the lateral decubitus position. The challenge during general anesthesia, particularly with the patient in the BCP, has been to ascertain the lower limit of blood pressure autoregulation, correctly measure mean arterial pressure, and adequately adjust parameters to maintain cerebral perfusion. There is increasing concern about the BCP and its association with intraoperative cerebral desaturation events (CDEs). Assessment of CDEs intraoperatively remains difficult; the emerging technology near-infrared spectroscopy (NIRS) may provide noninvasive, inexpensive, and continuous assessment of cerebral perfusion, offering an "early warning" system before irreversible cerebral ischemia occurs. METHODS: A systematic review was undertaken to determine the incidence of intraoperative CDEs as measured by NIRS and whether it is possible to risk stratify patients for intraoperative CDEs, specifically the degree of elevation in the BCP. RESULTS: Searching Medline, Embase, and the Cochrane Central Register of Controlled Trials from inception until December 30, 2013, we found 9 studies (N = 339) that met our search criteria. The Level of Evidence was III or IV. CONCLUSIONS: There remains a paucity of high-level data. The mean incidence of CDEs was 28.8%. We found a strong positive correlation between CDEs and degree of elevation in the BCP (P = .056). Emerging evidence (Level IV) suggests that we may be able to stratify patients on the basis of age, history of hypertension and stroke, body mass index, diabetes mellitus, obstructive sleep apnea, and height. The challenge remains, however, in defining the degree and duration of cerebral desaturation, as measured by NIRS, required to produce measureable neurocognitive decline postoperatively. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.

Mid-term outcome of total hip replacement using the posterior approach for displaced femoral neck fractures.

Treatment of displaced femoral neck fractures with total hip replacement (THR) in appropriately selected patients has become more widely accepted. The use of the posterior approach for THR remains controversial due to concerns regarding dislocation, the cause of which is multi-factorial. This study is a single surgeon series of 45 consecutive active, healthy patients (mean age 78 years) with displaced femoral neck fractures treated with THR through a posterior approach. Large diameter heads (32mm in 47%, ≥36mm in 48% of patients) and an anatomic posterior soft tissue repair were utilised to minimize the risk of dislocation. Outcomes were reported at a mean of 2 and 6 years. The mortality rate was 13% at 2 years and 40% at 6 years. All revision surgery (4.4%) was performed for dislocations which occurred in 6.7% of patients. Good VAS pain, OHS and SF-12 scores were reported both at 2 and 6 years. Patient satisfaction with the results of surgery was high.

Operative outcome of displaced medial-end clavicle fractures in adults.

The results following nonoperative treatment of displaced, medial end clavicle fractures is often unsatisfactory; but no study has yet reported the outcome of operative fixation of these fractures. This study reports the results of open reduction and internal fixation on displaced, medial end clavicle fractures, in five adult patients (aged 25-52 years, mean 43) including 1 patient with a nonunion. The mean follow-up was 3.3 years (8 months-10.3 years). All fractures had united clinically and radiologically. No complications occurred, and no revision surgery was required. VAS pain scores averaged 0.75 (0-2) at rest, 0.75 (0-2) for normal activities, and 1.0 (0-2) for heavy activities. The mean DASH score was 9.0 (0-17), and all patients were very satisfied with the results of surgery (VAS 10). All patients had a full range of motion of their shoulder at final follow-up and were able to return to pre-injury occupational and activity levels.

Pediatric complex regional pain syndrome.

Complex regional pain syndrome (CRPS) is a relatively new diagnostic entity in pediatrics. There is debate as to what constitutes the most effective treatment for pediatric CRPS. This study presents the patient characteristics, clinical course, and treatment outcome of 20 children diagnosed with CRPS at a major children's hospital during a 4-year period. The results showed that pediatric CRPS occurs predominantly in girls (90%) in later childhood and adolescence (mean age, 11.8 [range, 8-16 years]). It affects mainly the lower limbs (85%), with a predilection for the foot (75% of all cases), and was frequently initiated by minor trauma (80%). In many cases, there was a lengthy time to diagnosis (mean, 13.6 weeks) that delayed the institution of treatment, which consisted of intensive physiotherapy and psychological therapy. Most children (70%) required adjuvant medications (amitriptyline and/or gabapentin) for analgesia and to enable them to participate in physiotherapy. A high percentage of children had complete resolution of symptoms using this treatment regime (mean, 15.4 weeks [range, 3 days to 64 weeks]), but 40% required treatment as a hospital inpatient and 20% had a relapse episode. In conclusion, pediatric CRPS is under-recognized by clinicians, resulting in diagnostic delays, but has a favorable outcome to noninvasive treatment in that complete resolution of symptoms and signs occur in most patients. However, the lengthy period to achieve symptom resolution in some children and a high relapse rate support the need for further research into other treatment modalities.
