Total shoulder arthroplasty (TSA) and Reverse Total shoulder arthroplasty (RSA) are two of the most performed shoulder operations today. Traditionally postoperative rehabilitation included a period of immobilisation, protecting the joint and allowing time for soft tissue healing. This immobilisation period may significantly impact a patient's quality of life (Qol)and ability to perform activities of daily living (ADL's). This period of immobilisation could be safely avoided, accelerating return to function and improving postoperative QoL.

This systematic review examines the safety of early mobilisation compared to immobilisation after shoulder arthroplasty focusing on outcomes at one year.

Prompt mobilisation after the Fracture neck of femur surgery is one of the important key performance index (‘KPI caterpillar charts’ 2021) affecting the overall functional outcome and mortality. Better control of peri-operative blood pressure and minimal alteration of renal profile as a result of surgery and anaesthesia may have an implication on early post-operative mobilisation.

Aim was to evaluate perioperative blood pressure measurements (duration of fall of systolic BP below the critical level of 90mmHg) and effect on the post-operative renal profile with the newer short acting spinal anaesthetic agent (prilocaine and chlorprocaine) used alongside the commonly used regional nerve block. 20 patients were randomly selected who were given the newer short acting spinal anaesthetic agent along with a regional nerve block between May 2019 and February 2020. Anaesthetic charts were reviewed from all patients for data collection. The assessment criteria for perioperative hypotension: Duration of systolic blood pressure less than 90 mm of Hg and change of pre and post operative renal functions.

Only one patient had a significant drop in systolic BP less than 90mmHg (25 minutes). 3 other patients had a momentary fall of systolic BP of less than 5 minutes. None of the above patients had mortality and had negligible change in pre and post op renal function. Only one patient in this cohort had elevation of post-operative creatinine levels but did not have any mortality. Only 1 patient died on day 3 post operatively who had multiple comorbidities and was under evaluation for GI cancer. Even in this patient the peri-operative blood pressure was well maintained (never below 90mmHg systolic) and post-operative renal function was also shown to have improved (309 pre-operatively to 150 post-operatively) in this patient.

The use of short-acting spinal anaesthesia has shown to be associated with a better control of blood pressure and end organ perfusion, less adverse effects on renal function leading to early mobilisation and a more favourable patient outcome with reduced mortality, earlier mobilisation, shorter hospital stay and earlier discharge in this elderly patient cohort.

Total Knee Arthroplasty (TKA) improves the quality of life of osteoarthritic and rheumatoid arthritis patients, however, is associated with moderate to severe postoperative pain. There are multiple methods of managing postoperative pain that include epidural anesthesia but it prevents early mobilization and results in postoperative hypotension and spinal infection. Controlling local pain pathways through intra-articular administration of analgesics is a novel method and is inexpensive and simple. Hence, we assess the effects of postoperative epidural bupivacaine injection along with intra-articular injection in total knee replacement patients. The methodology included 100 patients undergoing TKA randomly divided into two groups, one administered with only epidural bupivacaine injection and the other with intra-articular cocktail injection. The results were measured based on a 10-point pain assessment scale, knee's range of motion (ROM), and Lysholm knee score. The VAS score was lower in the intra-articular cocktail group compared to the bupivacaine injection group until the end of 1-week post-administration (p<0.01). Among inter-group comparisons, we observed that the range of motion was significantly more in cocktail injection as compared to the bupivacaine group till the end of one week (p<0.05). Lysholm's score was significantly more in cocktail injection as compared to the bupivacaine group till the end of one week (p<0.05). Our study showed that both epidural bupivacaine injection and intra-articular injection were effective in reducing pain after TKA and have a comparable functional outcome at the end of 4 weeks follow up. However, the pain relief was faster in cases with intra-articular injection, providing the opportunity for early rehabilitation. Thus, we recommend the use of intra-articular cocktail injection for postoperative management of pain after total knee arthroplasty, which enables early rehabilitation and faster functional recovery of these patients

Abstract. In aged trauma patients the basic prerequisite is early mobilization and full weight-bearing, as immobilization can trigger various complications such as pressure ulcers, pneumonia, urinary tract infections and others. Mortality of elderly patients increases significantly in fracture patients with partial weight-bearing compared to populations with total weight-bearing. Besides the limited physical strength in these patients, partial-weight bearing is however frequently used for the aftercare of hip fracture patients. Therefore, the present study aims to evaluate mobility of aged hip fracture patients with regards to weight-bearing and postoperative mobility. Methods. An insole mobile force sensor was used to measure the post-operative weight-bearing by assessing the compressive forces between foot and shoe. Only patients (n=15) that suffered a trochanteric fracture >75 years of age were included and compared to a study group of patients (n=18) with fractures of the lower limb <40 years of age. Patients with cognitive disorders such as delirium and other diseases limiting the realization of partial weight-bearing were excluded. Both groups were instructed to maintain partial weight bearing of the affected limb following surgery. Following five days of training by our department of physiotherapy, the patients were requested to perform a gait analysis with the insole mobile force sensor. During gait analysis the maximum load was measured (kg) and the time over which the partial load could be maintained was determined. Results. None of the aged patients in the test group could meet the partial load at all times. 73.33% of patients (11 out of 15) exceeded the specified load by more than twice (> 40 kg). In the control group, 55.56% (10 of 18) of the patients were able to meet the partial load. A further 22.22% of the young patients (4 out of 18) were able to exceed only slightly (<120%, <24 kg). It was also shown that only 11.11% (2 of 18) put more than double of the allowed weight (> 40 kg) on the affected leg in the younger group. Only one of the aged patients was able to exceed the pre-determined weight-bearing restrictions for less than 10% of the measured time. In comparison, significantly more patients in the control group (88,89%; 16 of 18; p<0,05) were able to maintain the partial load for more than 90.0% of the time of gait analysis. Conclusion. Elderly patients seem to be unable to follow partial weight-bearing restrictions as proven in the present trial. As early mobilization of geriatric trauma patients is an important element for a successful rehabilitation, the relict of postoperative partial weight-bearing in these patients should be abandoned. Thus, the surgical therapy should allow immediate full weight bearing following surgery of aged hip fracture patients

Introduction and Objective. Plating of geriatric distal femoral fractures with Locking Compression Plate Distal Femur (LCP–DF) often requires augmentation with a supplemental medial plate to achieve sufficient stability allowing early mobilization. However, medial vital structures may be impaired by supplemental medial plating using a straight plate. Therefore, a helically shaped medial plate may be used to avoid damage of these structures. Aim of the current study was to investigate the biomechanical competence of augmented LCP–DF plating using a supplemental straight versus helically shaped medial plate. Materials and Methods. Ten pairs of human cadaveric femora with poor bone quality were assigned pairwise for instrumentation using a lateral anatomical 15-hole LCP–DF combined with a medial 14-hole LCP, the latter being either straight or manually pre-contoured to a 90-degree helical shape. An unstable distal femoral fracture AO/OTA 33–A3 was simulated by means of osteotomies. All specimens were biomechanically tested under non-destructive quasi-static and destructive progressively increasing combined cyclic axial and torsional loading in internal rotation, with monitoring by means of optical motion tracking. Results. Initial axial stiffness and torsional stiffness in internal and external rotation for straight double plating (548.1 ± 134.2 N/mm, 2.69 ± 0.52 Nm/° and 2.69 ± 0.50 Nm/°) was significantly higher versus helical double plating (442.9 ± 133.7 N/mm, 2.07 ± 0.32 Nm/° and 2.16 ± 0.22 Nm/°), p≤0.04. Initial interfragmentary axial displacement and flexural rotation under 500 N static loading were significantly smaller for straight plating (0.11 ± 0.14 mm and 0.21 ± 0.10°) versus helical plating (0.31 ± 0.14 mm and 0.68 ± 0.16°), p<0.01. However, initial varus deformation under this loading remained not significantly different between the two fixation methods (straight: 0.57 ± 0.23°, helical: 0.75 ± 0.34°), p=0.08. During dynamic loading, within the course of the first 4000 cycles the movements of the distal fragment in flexion were significantly bigger for helical over straight plating (1.03 ± 0.33° versus 0.40 ± 0.20°), p<0.01. However, no significant differences were observed between the two fixation methods in terms of varus, internal rotation, axial and shear displacements at the fracture site, and number of cycles to failure. Conclusions. Augmented lateral plating of unstable distal femoral fractures with use of supplemental helically shaped medial plate was associated with more elastic bone-implant construct behavior under static and dynamic loading compared to straight double plating. Both fixation methods resulted in comparable number of cycles to failure. From a biomechanical perspective, the more elastic helical double plating may be considered as useful alternative to straight plating, potentially reducing stress risers at the distal bone-implant interface due to its ameliorated damping capacities

Introduction. Distal triceps tendon rupture is related to high complication rates with up to 25% failures. Elbow stiffness is another severe complication, as the traditional approach considers prolonged immobilization to ensure tendon healing. Recently a dynamic high-strength suture tape was designed, implementing a silicone-infused core for braid shortening and preventing repair elongation during mobilization, thus maintaining constant tissue approximation. The aim of this study was to biomechanically compare the novel dynamic tape versus a conventional high-strength suture tape in a human cadaveric distal triceps tendon rupture repair model. Method. Sixteen paired arms from eight donors were used. Distal triceps tendon rupture tenotomies and repairs were performed via the crossed transosseous locking Krackow stitch technique for anatomic footprint repair using either conventional suture tape (ST) or novel dynamic tape (DT). A postoperative protocol mimicking intense early rehabilitation was simulated, by a 9-day, 300-cycle daily mobilization under 120N pulling force followed by a final destructive test. Result. Significant differences were identified between the groups regarding the temporal progression of the displacement in the distal, intermediate, and proximal tendon aspects, p<0.001. DT demonstrated significantly less displacement compared to ST (4.6±1.2mm versus 7.8±2.1mm) and higher load to failure (637±113N versus 341±230N), p≤0.037. DT retracted 0.95±1.95mm after each 24-hour rest period and withstood the whole cyclic loading sequence without failure. In contrast, ST failed early in three specimens. Conclusion. From a biomechanical perspective, DT revealed lower tendon displacement and greater resistance in load to failure over ST during simulated daily mobilization, suggesting its potential for earlier elbow mobilization and prevention of postoperative elbow stiffness

Standard fixation for intra-articular distal humerus fracture is open reduction and internal fixation (ORIF). However, high energy fractures of the distal humerus are often accompanied with soft tissue injuries and or vascular injuries which limits the use of internal fixation. In our report, we describe a highly complex distal humerus fracture that showed promising healing via a ring external fixator. A 26-year-old man sustained a Gustillo Anderson Grade IIIB intra-articular distal humerus fracture of the non-dominant limb with bone loss at the lateral column. The injury was managed with aggressive wound debridement and cross elbow stabilization via a hinged ring external fixator. Post operative wound managed with foam dressing. Post-operatively, early controlled mobilization of elbow commenced. Fracture union achieved by 9 weeks and frame removed once fracture united. No surgical site infection or non-union observed throughout follow up. At 2 years follow up, flexion - extension of elbow is 20°- 100°, forearm supination 65°, forearm pronation 60° with no significant valgus or varus deformity. The extent of normal anatomic restoration in elbow fracture fixation determines the quality of elbow function with most common complication being elbow stiffness. Ring fixator is a non-invasive external device which provides firm stabilization of fracture while allowing for adequate soft tissue management. It provides continuous axial micro-movements in the frame which promotes callus formation while avoiding translation or angulation between the fragments. In appropriate frame design, they allow for early rehabilitation of joint where normal range of motion can be allowed in controlled manner immediately post-fixation. Functional outcome of elbow fracture from ring external fixation is comparable to ORIF due to better rehabilitation and lower complications. Ring external fixator in our patient achieved acceptable functional outcome and fracture alignment meanwhile the fracture was not complicated with common complications seen in ORIF. In conclusion, ring external fixator is as effective as ORIF in treating complex distal humeral fractures and should be considered for definitive fixation in such fractures

The goals of perioperative management are to relieve pain, achieve early mobilization after surgery, reduce length of hospital stay, and obtain adequate patient satisfaction. Several treatment options combining systemic analgesics and/or regional analgesia with or without opioids are available for postoperative pain; however, a gold standard has not been established although there is a progressive shift towards multimodal approaches to improve analgesia while minimizing opioid-related side effects. EX-TRA-05 (DAVID-ART) was a randomised, double-blind, parallel, pivotal study, evaluating the analgesic efficacy and safety of the innovative oral combination of dexketoprofen/tramadol 25mg/75mg in comparison with the individual components (tramadol given at the higher dose of 100mg) on moderate to severe acute pain after total hip replacement. Repeated doses of study drug were administered every 8 hours and pain intensity (PI) was to be scored according to a 100mm visual analogue scale (VAS) on a programmed e-diary every 2 hours over a 56-hour period (i.e. along 7 repeated doses). A placebo arm was included at the first administration to validate the pain model. Rescue medication, metamizole 500mg, was available during the treatment period. The study primary endpoint was the mean sum of the pain intensity difference values throughout the first 8 hours (SPID. 8. ), which considered the 3 active treatment arms and placebo (ITT population; N=641). In this phase, a clear superiority of the combination over the single agents was demonstrated (p<0.05). An additional analysis was performed during the entire 0–56h repeated-dose period excluding those patients who had received placebo at the first dose (N=161). The estimated mean (SE) differences on PI-VAS over 24, 32 and 56 hours post first dose (0–24h, 0–32h, and 0–56h) between the combination and each single agent were evaluated. Patients who received active analgesic from the first dose (mITT population; N=480) were aged 29–80 years (42% were ≥65 years). At randomisation, pain was moderate (≥40–60mm) in 51% patients and severe (>60mm) in 49%. For dexketoprofen/tramadol, mean (SD) PI-VAS values were 22 (4.0) over 24 hours; 21 (4.1) over 32 hours; and 19 (3.8) over 56 hours. The estimated differences versus dexketoprofen 25mg and tramadol 100mg were respectively 10 (0.7) and 7.6 (0.7) over 24 hours; 9.8 (0.6) and 7.2 (0.6) over 32 hours; and 8.1 (0.5) and 6.3 (0.5) over 56 hours (p<0.0001 for all comparisons), which confirmed the superiority of the combination versus both single agents throughout the periods analysed. This significant higher decrease of PI favouring dexketoprofen/tramadol 25mg/75mg over dexketoprofen 25mg and tramadol 100mg, all given every 8 hours, during the first 56 hours post dose confirmed the superior analgesia shown after the first 0–8h post-dose period. The combination of dexketoprofen/tramadol 25mg/75mg is able to provide a level of analgesia above that achievable by each component alone, with a sustained effect when used as a multiple-dose regimen. The addition of this new combo to the analgesic armamentarium may contribute to facilitate early mobilization after surgery, thus positively impacting perioperative co-morbidities and length of in-hospital stay

Coronoid fractures account for 2 to 15% of the cases with elbow dislocations and usually occur as part of complex injuries. Comminuted fractures and non-unions necessitate coronoid fixation, reconstruction or replacement. The aim of this biomechanical study was to compare the axial stability achieved via an individualized 3D printed prosthesis with curved cemented intramedullary stem to both radial head grafted reconstruction and coronoid fixation with 2 screws. It was hypothesized that the prosthetic replacement will provide superior stability over the grafted reconstruction and screw fixation. Following CT scanning, 18 human cadaveric proximal ulnas were osteotomized at 40% of the coronoid height and randomized to 3 groups (n = 6). The specimens in Group 1 were treated with an individually designed 3D printed stainless steel coronoid prosthesis with curved cemented intramedullary stem, individually designed based on the contralateral coronoid scan. The ulnas in Group 2 were reconstructed with an ipsilateral radial head autograft fixed with two anteroposterior screws, whereas the osteotomized coronoids in Group 3 were fixed in situ with two anteroposterior screws. All specimens were biomechanically tested under ramped quasi-static axial loading to failure at a rate of 10 mm/min. Construct stiffness and failure load were calculated. Statistical analysis was performed at a level of significance set at 0.05. Prosthetic treatment (Group 1) resulted in significantly higher stiffness and failure load compared to both radial head autograft reconstruction (Group 2) and coronoid screw fixation, p ≤ 0.002. Stiffness and failure load did not reveal any significant differences between Group 2 and Group 3, p ≥ 0.846. In cases of coronoid deficiency, replacement of the coronoid process with an anatomically shaped individually designed 3D printed prosthesis with a curved cemented intramedullary stem seems to be an effective method to restore the buttress function of the coronoid under axial loading. This method provides superior stability over both radial head graft reconstruction and coronoid screw fixation, while achieving anatomical articular congruity. Therefore, better load distribution with less stress at the bone-implant interface can be anticipated. In the clinical practice, implementation of this prosthesis type could allow for early patient mobilization with better short- and long-term treatment outcomes and may be beneficial for patients with irreparable comminuted coronoid fractures, severe arthritic changes or non-unions
