Age-related differences in cognition and postoperative quality of recovery after beach chair position shoulder surgery.

We examined the influence of age in beach chair position shoulder surgery and postoperative quality of recovery by conducting a single-site, observational, cohort study comparing younger aged (18-40 years) versus older aged (at least 60 years) patients admitted for elective shoulder surgery in the beach chair position. Endpoints were dichotomous return of function to each patient's individual preoperative baseline as assessed using the postoperative quality of recovery scale; measuring cognition, nociception, physiological, emotional, functional activities and overall perspective. We recruited 112 (41 younger and 71 older aged) patients. There was no statistical difference in cognitive recovery at day three postoperatively (primary outcome): 26/32 younger patients (81%) versus 43/60 (72%) older patients, P=0.45. Rates of recovery were age-dependent on domain and time frame (secondary outcomes), with older patients recovering faster in the nociceptive domain (P=0.02), slower in the emotional domain (P=0.02) and not different in the physiological, functional activities and overall perspective domains (all P >0.35). In conclusion, we did not show any statistically significant difference in cognitive outcomes between younger and older patients using our perioperative anaesthesia and analgesia management protocol. Irrespective of age, 70% of patients recovered by three months in all domains.

Reverse Shoulder Arthroplasty for the treatment of Proximal humeral fractures in the Elderly (ReShAPE trial) : study protocol for a multicentre combined randomised controlled and observational trial.

BACKGROUND: Proximal humeral fractures are common in older patients. The majority are minimally displaced and are associated with good outcomes after nonoperative treatment. Poorer outcomes are associated with displaced, multipart fractures. There is no clear benefit from surgical fracture fixation compared to nonoperative treatment. Replacement of the fractured humeral head with a hemiarthroplasty is another treatment option, but has not been shown to be clearly superior to nonoperative treatment or internal fixation. Recently, reverse total shoulder arthroplasty has been used to treat these fractures, particularly in the older population with several case series demonstrating good outcomes. No comparative trial has been performed to test the effectiveness of reverse total shoulder arthroplasty against nonoperative treatment. METHODS/DESIGN: ReShAPE (Reverse Shoulder Arthroplasty for the treatment of Proximal humeral fractures in the Elderly) is a multicenter combined randomized and observational study. The primary objective is to compare pain and function 12 months post fracture using the American Shoulder and Elbow Society (ASES) score in patients aged 70 years or older with three- and four-part proximal humeral fractures treated by either reverse shoulder arthroplasty or nonoperative treatment. Secondary outcome measures will include the DASH (Disability of the Arm, Shoulder and Hand) score, the EQ-5D (EuroQol Health Survey), the EQ-VAS, pain, radiological parameters and complications. DISCUSSION: The study will assess the effectiveness of reverse shoulder arthroplasty for complex proximal humeral fractures and thereby guide treatment of a common injury in the older population.

A systematic review and meta-analysis of clinical and patient-reported outcomes following two procedures for recurrent traumatic anterior instability of the shoulder: Latarjet procedure vs. Bankart repair.

BACKGROUND: The Bankart repair and Latarjet procedure are both viable surgical options for recurrent traumatic anterior instability of the shoulder joint. The anatomic repair is the more popular option, with 90% of surgeons internationally choosing the Bankart repair as the initial treatment. There has been no previous review directly comparing the 2 techniques. Hence, we aimed to systematically review studies to compare the outcomes of Bankart repairs vs. the Latarjet procedure for recurrent instability of the shoulder. METHODS: Six electronic databases were searched for original, English-language studies comparing the Bankart and Latarjet procedures. Studies were critically appraised using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. Data were extracted from the text, tables, and figures of the selected studies. RESULTS: Eight comparative studies were identified with 795 shoulders; 416 of them underwent open or arthroscopic Bankart repairs, and 379 were repaired by the open Latarjet procedure. Primary and revision procedures were studied. The Latarjet procedure conferred significantly lower risk of recurrence and redislocation. There was no significant difference in the rates of complication requiring reoperation between the two procedures. Rowe scores were higher and loss of external rotation lower in the Latarjet group compared with the Bankart repair group. CONCLUSIONS: Our studies demonstrate that the Latarjet procedure is a viable and possibly superior alternative to the Bankart repair, offering greater stability with no significant increase in complication rate. However, the studies identified were retrospective and of limited quality, and therefore randomized controlled trials with large populations of patients or prospective assessment of national orthopedic registries should be employed to confirm our findings.

Arthroscopic repair of type II SLAP lesions: Clinical and anatomic follow-up.

AIMS: The aim was to evaluate the clinical and anatomic outcome of arthroscopic repair of type II SLAP lesions. MATERIALS AND METHODS: The senior author performed isolated repairs of 25 type II SLAP lesions in 25 patients with a mean age of 40.0 ± 12 years. All tears were repaired using standard arthroscopic suture anchor repair to bone. All patients were reviewed using a standardized clinical examination by a blinded, independent observer, and using several shoulder outcome measures. Patients were evaluated by magnetic resonance imaging arthrogram at a minimum of 1-year postoperatively. STATISTICAL ANALYSIS USED: Two-tailed paired t-test were used to determine significant differences in preoperative and postoperative clinical outcomes scores. In addition, a Fisher's exact test was used. RESULTS: At a mean follow-up of 54-month, the mean American Shoulder and Elbow Surgeons Shoulder Index (ASES) scores improved from 52.1 preoperatively to 86.1 postoperatively (P < 0.0001) and the Simple Shoulder Test (SST) scores from 7.7 to 10.6 (P < 0.0002). Twenty-two out of the 25 patients (88%) stated that they would have surgery again. Of the 21 patients who had postoperative magnetic resonance imaging arthrographys (MRAs), 9 patients (43%) demonstrated dye tracking between the labrum bone interface suggestive of a recurrent tear and 12 patients (57%) had a completely intact repair. There was no significant difference in ASES, SST, and patient satisfaction scores in patients with recurrent or intact repairs. CONCLUSIONS: Arthroscopic repair of type II SLAP lesions demonstrated improvements in clinical outcomes. However, MRA imaging demonstrated 43% of patients with recurrent tears. MRA results do not necessarily correlate with clinical outcome.

Arthroscopic repair of massive, contracted, immobile tears using interval slides: clinical and MRI structural follow-up.

PURPOSE: The purpose of this study was to determine clinical and structural outcomes of arthroscopic repair of massive, contracted, immobile rotator cuff tears using interval slides. METHODS: Eleven patients who had rotator cuff tears that were irreparable using standard mobilization techniques, but were repaired using interval slides were reviewed. Patients were evaluated at mean 25.2 months (±10.3) post-operatively utilizing a standardized clinical examination and by magnetic resonance imaging (MRI). RESULTS: American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) scores improved significantly (ASES p = 0.0001; SST p = 0.0001) from pre- to post-operative. Range of motion in forward elevation and external rotation increased from pre- to post-operative, though not significantly. Strength via manual muscle testing improved on forward elevation (p = 0.001) and external rotation (p = 0.007) from pre- to post-operative. Post-operative MRI demonstrated massive re-tearing to the original size in 6 patients (55 %) and intact rotator cuffs with tissue spanning the defects in 5 (45 %) patients. CONCLUSIONS: In patients with massive, contracted, immobile tears, an interval slide technique may be utilized as a salvage procedure. Arthroscopic repair of massive, contracted, immobile rotator cuff tears using interval slide techniques can lead to good clinical and satisfactory structural outcomes. LEVEL OF EVIDENCE: IV.

Medial rotator cuff failure after arthroscopic double-row rotator cuff repair.

Persistent tendon defects after rotator cuff repair are not uncommon. Recently, the senior author has identified a subset of 5 patients (mean age, 52 years; range, 42 to 59 years) after arthroscopic double-row rotator cuff repair who showed an unusual mechanism of tendon failure. In these patients the tendon footprint appears well fixed to the greater tuberosity with normal thickness. However, medial to the intact footprint, the tendon is torn with full-thickness defects through the rotator cuff. All patients were involved in Workers' Compensation claims. Magnetic resonance arthrography showed an intact cuff footprint but dye leakage in all patients. Revision surgery was performed at a mean of 8.6 months after the index procedure and showed an intact rotator cuff footprint but cuff failure medial to the footprint. Four patients had repair of the defects by tendon-to-tendon side-to-side sutures, whereas one did not undergo repair. Medial-row failure of the rotator cuff is a previously unreported mechanism of failure after double-row rotator cuff repair. Given the small number of patients in this study, it is unclear whether these defects are symptomatic. However, repair of these defects resulted in improvement in pain in 4 of 5 patients.

Use of a retrograde femoral nail in a patient with McCune-Albright syndrome.

McCune-Albright Syndrome is a rare condition characterized by endocrine abnormalities, precocious puberty, pigmented skin lesions and polyostotic fibrous dysplasia with consequent fractures and limb deformity. Patients with this syndrome might have had multiple operations on a limb and might also have extensive internal fixation in-situ. We review the case of a 41-year-old woman with McCune-Albright syndrome, who presented with a pathological fracture of her left femur below a long plate and screws. Our management of this challenging problem included the use of a retrograde femoral nail, which, because of the need to retain pre-existing internal fixation, had to be locked proximally through a hole in a femoral plate. This technique, combined with reaming, and thus bone grafting of the fracture, and also perioperative infusions of pamidronate, allowed an early recovery and return to premorbid function for the patient. In the present study we detail our technique and discuss its advantages over other possible methods of treatment.
