Comparison of Functional Outcomes and Complications of Inlay and Onlay Reverse Shoulder Arthroplasty in Neer Type 4 Proximal Humerus Fractures and Cuff Tear Arthropathy: A Multicentric Study.

Background: This multicenter retrospective study was conducted with the objective of comparing the outcomes and complications between inlay and onlay reverse shoulder arthroplasty (RSA) in patients presenting Neer Type 4 proximal humerus fractures and cuff tear arthropathy. The primary aim of this investigation was to assess and juxtapose the clinical as well as functional outcomes of individuals who underwent onlay reverse shoulder arthroplasty with those who underwent inlay reverse shoulder arthroplasty. Methods: A retrospective cohort study was conducted, involving patients who had undergone reverse shoulder arthroplasty between the period of 2016 and 2022. The study divided the population into two groups: Group A received inlay humeral components, while Group B received onlay humeral components. Functional outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) and Constant scores. Range of motion, infection, periprosthetic fractures, and nerve injuries were also assessed. Results: The study included 67 patients in Group A and 62 patients in Group B. Group A had significantly better functional outcomes, as indicated by higher ASES and Constant scores (p < 0.05). Group A also had greater shoulder joint motion (p < 0.05). Periprosthetic fractures were significantly more common in Group B (p < 0.05). However, complication rates, including infection and instability, did not significantly differ between the groups (p > 0.05). Nerve injuries occurred in both groups, with slightly higher occurrence in Group B. Conclusion: Inlay humeral components in reverse shoulder arthroplasty for Neer Type 4 fractures and cuff tear arthropathy resulted in better functional outcomes, increased range of motion, and lower incidence of periprosthetic fractures compared to onlay components. Onlay components showed potential advantages in reducing instability rates. Further studies with larger samples and standardized protocols are needed to confirm these findings.

Pectoralis major pedicle bone grafting vs. tricortical iliac grafting for Neer 4-part proximal humerus fractures: a randomized controlled trial.

BACKGROUND: The risk of avascular necrosis, nonunion, or malunion is high in osteoporosis-related 4-part fractures. We evaluated the results of patients who underwent plate osteosynthesis with a vascularized pectoralis major graft compared with tricortical iliac grafting to treat 4-part proximal humerus fractures. MATERIAL AND METHODS: Thirty-four patients aged 50-75 years with Neer 4-part proximal humerus fractures were studied. Group A (n = 17) underwent osteotomy of a 2.5 ± 1 cm pectoralis major pedicle bone graft and plate application, whereas group B (n = 17) underwent plate osteosynthesis using iliac autogenous grafts. Final follow-up assessments included evaluation using Constant and American Shoulder and Elbow Surgeons scoring systems, humeral neck-shaft angle (HNSA), humeral head height, and humeral head avascular necrosis. RESULTS: Reduction loss was observed in 3 patients (17.6%) in group A, whereas it was observed in 10 patients (58.8%) in group B (P = .013). Humeral head avascular necrosis was found in 1 patient (5.8%) in group A, whereas it was found in 5 patients (29.4%) in the other group (P = .071). The HNSA was normal in 12 (70.5%) of group A patients, whereas it was normal in 6 (35.2%) of group B patients. The HNSA was weak or bad (<1200) in 29.4% of group A patients, whereas this rate was 64.7% in group B patients. Humeral head height was 2.64 ± 1.45 mm in group A and 3.66 ± 1.65 mm in group B. There were no statistically significant differences between the 2 groups in terms of Constant and American Shoulder and Elbow Surgeons scoring systems. CONCLUSION: Pectoralis major bone pedicle graft in Neer 4-part proximal humerus fractures reduces the risk of avascular necrosis and nonunion rates. Our technique yielded excellent clinical and radiological results. We achieved recovery without creating additional donor site morbidity.

Comparison of Supination-Adduction Type 2 and Supination-External Rotation Type 4 in Bimalleolar Ankle Fractures: Does Partial Pylon Variant of Supination-Adduction Type Fracture Affect Functional Outcomes?

BACKGROUND: Supination-adduction (SAD) type injuries are pylon variant injuries and lie between partial intra-articular pylon fractures and rotational ankle fractures. We aimed to evaluate functional outcomes of SAD type 2 bimalleolar fractures in comparison to supination-external rotation (SER) type 4 fractures. METHODS: We retrospectively reviewed data of 42 cases with SER type 4 and 20 cases with SAD type 2 injuries. Patients with a history of rheumatic disease, open fractures, pathologic fractures, nonbimalleolar fractures, neuropathic disease, and talus osteochondral lesion, and those operated on after greater than 72 hours because of skin lesion or managed with a two-stage surgical protocol after external fixation, were not included in the study. We compared these two groups in terms of the mean age, follow-up time, visual analog scale pain and American Orthopedic Foot and Ankle Society scores, Kellgren-Lawrence arthrosis classification, union time, and complications. RESULTS: The groups did not differ in terms of mean age (P = .115) and sex (P = .573). There was no significant difference in terms of union time between the groups (P = .686). American Orthopedic Foot and Ankle Society score was significantly higher in the SER group (91.2 ± 9.9) than in the SAD group (86.1 ± 13.2; P = .034). Visual analog scale pain scores were similar in the SAD (0.3 ± 0.92) and the SER (0.26 ± 0.7) groups (P = .897). CONCLUSIONS: Supination-adduction bimalleolar fractures may have worse functional outcomes in the intermediate term than do SER bimalleolar fractures, implying pylon variant fractures as a mechanism of injury. Supination-adduction bimalleolar fractures might be associated with a high rate of intra-articular cartilage impaction, resulting in varus deformity after surgery.

Arthroscopic Biological Augmentation With Subacromial Bursa for Bursal-Sided Partial-Thickness Rotator Cuff Tears.

Background: Augmentation with subacromial bursa has not been fully established in bursal-sided partial-thickness rotator cuff tears (PT-RCTs). Purpose: To compare the results of acromioplasty + arthroscopic debridement versus acromioplasty + augmentation with subacromial bursa for Ellman type 2 PT-RCTs involving 25% to 50% of the tendon surface area. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 40 patients (mean age, 47.8 years) with Ellman type 2 PT-RCTs whose symptoms did not regress despite 3 months of nonoperative treatment. The patients underwent either acromioplasty + debridement (group A; n = 18) or acromioplasty + augmentation (group B; n = 22). Outcome scores (visual analog scale [VAS] pain score, Constant-Murley score [CMS], and American Shoulder and Elbow Surgeons [ASES] score) were obtained preoperatively and at 6, 12, and 18 months postoperatively. Magnetic resonance imaging (MRI) scans performed at 6 months postoperatively were used to determine the integrity and state of healing. Results: There were no significant differences between groups A and B in preoperative VAS, CMS, or ASES scores, and patients in both groups saw significant improvement at each follow-up time point on all 3 outcome scores (P = .001 for all). Scores on all 3 outcome measures were significantly better in group B than group A at each postoperative time point (P < .05 for all). Postoperative MRI scans revealed persistent partial tears in 5 of 18 patients in group A compared with 2 of 22 patients in group B (P < .05). Conversion to full-thickness tear (3/18 patients) was seen only in group A. Conclusion: Patients who underwent biological augmentation of their PT-RCTs had improved outcome scores compared with those treated with acromioplasty and debridement alone.

Does forearm position matter in subpectoral biceps tenodesis? A randomised controlled trial.

INTRODUCTION: The optimal position of the elbow and forearm during biceps tenodesis is a debated topic. The aim of our study was to compare two different forearm positions, pronation-extension (PE) or neutral, for fixation of the long head of the biceps tendon (LHB) in biceps tenodesis. MATERIALS AND METHODS: Fifty patients who underwent shoulder arthroscopy between February 2016 and January 2019 were included in our study. After diagnostic arthroscopy, the LHB was cut from its origin with a thermal ablator. The LHB was then tenodesed beneath the inferior border of the pectoralis major tendon for 25 patients in the PE position and for 25 patients in the neutral position. Patients were evaluated preoperatively and 3rd, 6th and 12th months postoperatively according to the visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) shoulder and Constant scores. Flexion and supination force measurements were made with a digital dynamometer device, compared to the healthy side for both groups. RESULTS: ASES and VAS scores were statistically better in the PE group compared with the neutral group (p < 0.05), but there was no statistically significant difference between Constant scores at 3 and 6 months (p > 0.05). No significant difference was found in both groups for 3 scores at 12 months. Comparison of the PE group with the contralateral extremity and comparing the neutral group with the contralateral extremity in terms of flexion strength showed no statistically significant difference. No statistically significant difference was found between the supination powers of both comparative groups. CONCLUSION: Functional scoring in the PE position is better at 3 and 6 months because patients experience less pain at 3 and 6 months. The simple change of the fixation position causes patients to feel less pain in the early period.

Feasibility of diagnosing osteoporosis using routine computed tomography scans for hip fractures: Correlation with histopathological diagnosis of head and neck regions.

OBJECTIVE: The aim of this study was to demonstrate the feasibility of diagnosing osteoporosis through routine computed tomography (CT) by assessing the association between the histopathological assessment of femoral head specimens extracted from patients who underwent surgery for intertrochanteric fractures and the Hounsfield unit (HU) measurements derived from preoperative CT scans. METHODS: Forty-eight patients who presented to our clinic between November 2019 and May 2020 with hip fractures and underwent partial prosthesis fixation were included in this retrospective study. Hounsfield unit measurements were performed on the head and neck regions using dual-energy x-ray absorptiometry (DEXA) and CT scans, respectively. The trabecular ratio per unit area was calculated using the Nikon Imaging Software (NIS-Elements ) program in the pathology laboratory from digitally captured images of the removed head and neck specimens. RESULTS: The mean HU receiver operating characteristic analysis had a sensitivity of 77% and a specificity of 87%, with a cutoff value of 77.68. There was a moderate correlation between the mean trabecular density and the mean HU of the femoral head (P=0.013, r=0.340). Additionally, there was a significant correlation between the mean HU and the T-score of the head, although this correlation was not found with the maximum-minimum HU. Although there was a significant correlation between trabecular density and mean HU, the correlation coefficient indicated a moderate relationship. This relationship was also observed between the inferior sections of the head and the trabecular density and HU (P=.018). However, no significant correlation was found between the T-score and the trabecular structure of the head (P=.977). CONCLUSION: The results of the present study suggest that conventional CT has the potential to serve as a diagnostic tool for osteoporosis and may offer a more precise and accurate method for evaluating the success of intraosseous implants when compared to T-scores without the need for additional tests or procedures.

Shoulder Proprioception Following Reverse Total Shoulder Arthroplasty for Unreconstructable Upper Third Fractures of the Humerus: 2-Year Outcomes.

Background: Proximal humerus fractures may be comminuted in the elderly or after injury with high-energy mechanisms. Reverse total shoulder arthroplasty that may affect shoulder proprioception (rTSA) has also begun to play a part in treating acute proximal humeral fractures. In this study, the authors aimed to evaluate joint position sense (JPS) after rTSA. Methods: Humac Norm II isokinetic device was used to evaluate the joint position sense. A joint angle was determined and the ability of the patient to create the same value of the angle by the active movement was evaluated. The difference between the pre-determined angle and the patient's measured angle was recorded. For proprioceptive sense, the initial position was 0° and the determination position was 30°, 60°, and 90° for flexion and abduction, and 15° and 30° for internal rotation and external rotation. Results: While both the mean Constant and ADLEIR scores did not differ between non-operated and operated sides, the mean proprioception differences in all flexion (30°, 60°, and 90°), abduction (30°, 60°, and 90°), internal rotation (15° and 30°), and external rotation (15° and 30°) were significantly higher in the operated side than that in non-operated side (p < 0.01 for each pairwise comparison). Conclusion: Reverse total shoulder arthroplasty (rTSA) treatment, which has increasingly become a surgical option in un-reconstructable proximal humeral fractures has significant adverse effects on proprioception on the operated side and may pose a risk for long-term instability, premature loosening, and prosthesis mechanical complications, in this context, well-designed prospective controlled studies are required.

Does Sectioning and Then Repairing of the Calcaneofibular Ligament at Subtalar Approach Lead to Residual Lateral Ankle Instability?

Background: The calcaneofibular ligament is cut to increase vision in surgical field in minimally invasive surgery of displaced intraarticular calcaneus fractures with subtalar incision. We aimed to investigate whether this causes talar tilt instability in ankle stress radiographs due to the calcaneofibular ligament deficiency in postoperative period. Methods: The files of 38 patients who were operated with the diagnosis of displaced calcaneus fracture between 2013 and 2018 were examined retrospectively. All the cases underwent with subtalar approach and the calcaneofibular ligament was repaired after the operation. The age, sex, injury mechanism, follow-up length, type of fracture by the Sanders classification, preoperative and postoperative Bohler's and Gissane's angle measurements, talar tilt measurements of intact and fractured side, postoperative calcaneal length, calcaneal height and calcaneal width of the cases were recorded. The obtained data were evaluated statistically. Results: 31 (81.6%) of the cases were men, seven (18.4%) were women. The average age was 31.92±7.95 years. The average follow-up time was 15.82±3.33 months. The preoperative Bohler's angle was 14.16±3.67 degree, while the postoperative Bohler's angle was 31.53±4.60 degree (P<0.05). The average talar tilt was 0.96±0.87 degrees on the intact side and 1.19±1.12 degrees on the fractured side (P:0.001). Although the talar tilt values were statistically higher on the fractured side than the intact side, no radiological instability finding was found in any case. The average postoperative Gissane's angles were 126.45±6.69 degrees. The calcaneal length (P:0.665), calcaneal width (P:0.212) and calcaneal height (P:0.341) were statistically similar between the postoperative fractured foot and intact foot. Conclusion: Sectioning of the calcaneofibular ligament in the surgical treatment with subtalar approach does not cause lateral ankle instability in stress radiographs but may cause laxity. Possible postoperative lateral ankle injuries can be prevented by ankle proprioception exercises.

Kinesiotaping therapy for midshaft clavicular fractures: a randomised trial study.

Midshaft clavicle fractures with shortening by less than 2 cm or minimal displacement without neurovascular injury can be treated conservatively. We hypothesized that kinesiotaping reduces the disadvantages of conservative treatment, such as early-phase pain, high nonunion rates, and a prolonged time to return to work, and yields better clinical and functional outcomes. Forty patients were randomly divided into the arm slings only (group S) or arm sling with kinesiotaping therapy group (group K). The outcome measures included the visual analog scale (VAS) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, union time, magnitude of shortening, and time to return to work. The mean follow-up period of the study was 8.5 (6- 10) months. The ASES and Constant scores were significantly better in group K than in group S in the 3rd month. The mean union time was 8.60 (8-12) weeks in group S and 8.25 (6-12) weeks in group K. The mean time to return to work was 7.23 (4-12) weeks in group S and 5.37 (2-10) weeks in group K, and the difference was statistically significant (p <0.05). There was no significant difference in terms of shortening between the two groups. Compared with an arm sling only, an arm sling with kinesiotaping can yield better clinical functional results, higher union rates, and a shorter the time to return to work due to the early control of pain and edema.

The effect of gluteus maximus tenotomy in primary total hip arthroplasty with posterior approach: Kinematic analysis of hip extensor strength.

BACKGROUND: The posterior approach (PA) is the most commonly used surgical approach for total hip arthroplasty (THA), but the proximity of the sciatic nerve may increase the likelihood of sciatic nerve injury (SNI). Gluteus maximus tenotomy can be performed to prevent SNI because tenotomy increases the distance between the femoral neck and sciatic nerve and prevents compression of the sciatic nerve by the gluteus maximus tendon (GMT) during hip movements. We aimed to kinematically compare the postoperative hip extensor forces of patients who have and have not undergone gluteus maximus tenotomy to determine whether there is a difference in hip extensor strength. METHODS: Seventy-two patients who underwent gluteus maximus tenotomy during THA were included in the group 1, and 86 patients who did not undergo tenotomy were included in group 2. The Harris hip score, body mass index and hip extensor forces were measured both preoperatively, and 6 months after surgery with an isokinetic dynamometer and compared. RESULTS: The mean age was 64.6 ± 2.3 years in group 1 and 63.8 ± 2.1 in group 2. Mean body mass index was 25.7 ± 1.1 in group 1, and 25.5 ± 1.3 in group 2. Baseline Harris hip score (HHS) was 42.36 ± 12 in group 1 and 44.07 ± 9.4 in group 2 (p = 0.31), whereas it was 89.1 ± 7.8 and 88.4 ± 8.1 at 6 months after surgery, respectively. Baseline hip extensor force (HEF) was 2 ± 0.4 Nm/kg in group 1, and 2.1 ± 0.7 Nm/kg in group 2 (p = 0.28), while it was 2.4 ± 0.6 Nm/kg, and 2.5 ± 0.5 Nm/kg, respectively at 6 month follow-up (p = 0.87). Both groups had significantly improved HHS and HEF when comparing baseline and postoperative measurements (p < 0.0001). No cases of sciatic nerve palsy were noted in group 1, whereas there were two (2.32%) cases in group 2, postoperatively. CONCLUSION: The release of the GMT during primary hip arthroplasty performed with the PA did not lead to significant decrease in hip extension forces. Hip extensor strength improves after THA regardless of tenotomy. Gluteus maximus tenotomy with repair does not reduce muscle strength and may offer better visualization.

Does Localisation of Fracture Line, According to Epicondyles, Affect Ligamentotaxis Negatively in Displaced Pediatric Supracondylar Humerus Fractures?

OBJECTIVE: To investigate the effect of localisation of the fracture line according to the trans-epicondylar line on open reduction rates and postoperative reduction quality. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Orthopedic and Traumatology, Prof. Dr. Cemil Tascioglu City Hospital, Istanbul, Turkey, from January 2011 to December 2018. METHODOLOGY: Pediatric cases (37 females-54 males) which underwent surgery with Gartland type three supracondylar humerus fracture having extension deformity, were included and examined retrospectively. Localisation of fracture line according to trans-epicondylar line, presence of postoperative rotation, sagittal and coronal deformity, reduction type and surgery duration were noted. RESULTS: According to trans-epicondylar level, fracture line passed through upper level of the line in 68 cases, while it passed through lower level in 23 cases. Rotation rate of patients, whose fraction line localisation was lower according to trans-epicondylar level (60.87%), was higher than upper localization patients (8.82%, p<0.001). It has been observed that the relation between localisation of fracture line according to trans-epicondylar level and sagittal deformity, coronal deformity, reduction type and surgery durations were similar (p>0.05). CONCLUSION: Determination of localisation of fracture line according to trans-epicondylar level in preoperative roentgenograms may allow the surgeon to predict the possibility of postoperative rotation deformity. Key Words: Fracture line, Humerus, Supracondylar, Pediatric, Epicondyle.

Mini-plate fixation via sinus tarsi approach is superior to cannulated screw in intra-articular calcaneal fractures: A prospective randomized study.

OBJECTIVE: Intra-articular displaced calcaneal fractures are common fractures and are often treated with surgical interventions. Sinüs tarsi approach provides secure access to lateral wall and joint facets. The aim of the study is to compare cannulated screw (CS) fixation and mini-plate (MP) fixation via sinus tarsi approach with Sanders types 2 and 3 fracture of calcaneus. METHODS: Sixty patients with Sanders types 2 and 3 calcaneal fracture underwent surgical intervention were randomly allocated into two groups as group MP fixation and group CS fixation regarding osteosynthesis method for 5-year period. Open reduction via sinüs tarsi approach was performed in both groups. Demographic variables, time to surgery (TS), operation duration (OD), length of hospital stay (LOS), surgical complications, and reoperations were recorded. Pre- and postoperative Gissane and Böhler angles; calcaneal length, height, and width; ankle anterior-posterior (AP) and lateral X-rays; and computed tomography were also recorded for radiological evaluation and fracture characteristics. Maryland Foot Score (MFS) was used to evaluate functional outcomes. RESULTS: Preoperative age, type of fracture, calcaneal length, height, and Gissane and Böhler angles, TS, LOS, and OD were not different between the groups. The postoperative calcaneal widening was significantly better restored in group MP compared with that of group CS. The incidence of reoperation and algoneurodystrophy was statistically higher in group CS than group MP. MFS in group MP was also higher than group CS at final visit. CONCLUSION: MP fixation via sinus tarsi approach is superior to CS fixation in Sanders types 2 and 3 calcaneal fractures.

Hindfoot Valgus following Interlocking Nail Treatment for Tibial Diaphysis Fractures: Can the Fibula Be Neglected?

Purpose. We evaluated whether intramedullary nail fixation for tibial diaphysis fractures with concomitant fibula fractures (except at the distal one-third level) managed conservatively with an associated fibula fracture resulted in ankle deformity and assessed the impact of the ankle deformity on lower extremity function. Methods. Sixty middle one-third tibial shaft fractures with associated fibular fractures, except the distal one-third level, were included in this study. All tibial shaft fractures were anatomically reduced and fixed with interlocking intramedullary nails. Fibular fractures were managed conservatively. Hindfoot alignment was assessed clinically. Tibia and fibular lengths were compared to contralateral measurements using radiographs. Functional results were evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Foot and Ankle Disability Index Score (FADI). Results. Anatomic union, defined as equal length in operative and contralateral tibias, was achieved in 60 fractures (100%). Fibular shortening was identified in 42 fractures (68%). Mean fibular shortening was 1.2 cm (range, 0.5-2 cm). Clinical exams showed increased hindfoot valgus in 42 fractures (68%). The mean KOOS was 88.4, and the mean FADI score was 90. Conclusion. Fibular fractures in the middle or proximal one-third may need to be stabilized at the time of tibial intramedullary nail fixation to prevent development of hindfoot valgus due to fibular shortening.
