BMC Musculoskeletal Disorders Jun 2024Most studies infer increasing incidence of proximal humeral fractures (PHF) from the 1950´s until the 1990´s. Recent time trends are less clear.
BACKGROUND
Most studies infer increasing incidence of proximal humeral fractures (PHF) from the 1950´s until the 1990´s. Recent time trends are less clear.
OBJECTIVES
Our primary objective was to identify time trends in the age- and sex-adjusted adult incidence of PHF in Malmö, Sweden, from year 1944 until 2020. Our secondary objectives were to describe the variation in incidence according to age, the monthly distribution, and to compare data from the two most recent decades with earlier.
STUDY DESIGN AND METHODS
Malmö has one emergency hospital where acute fractures are treated. We identified PHF in adult patients (≥ 18 years) by reviewing relevant radiology examinations during 17 sample years from year 1944 to 2020. We used jointpoint analyses to estimate time trends.
RESULTS
We identified 3 031 PHF during the study period (3 231 161 person years), 73% were sustained by women with mean age of 69 years (mean age in men 59). Joinpoint analyses indicated an increase in the age- and sex-adjusted incidence of PHF from year 1944 (52 per 100 000 person years) until 1977 (120 per 100 000) and thereafter a decrease until 2020 (85 per 100 000). A seasonal variation with more fractures during winter months, was apparent in earlier but not recent decades.
CONCLUSIONS
The age- and sex-adjusted incidence of PHF increased in Malmö, Sweden, from the 1940´s until year 1977 and thereafter decreased until 2020. More fractures were seen during winter months in earlier but not recent decades.

BACKGROUND
While prevention protocols have been implemented, skiing-related musculoskeletal injuries and concussions continue to present to emergency departments in the United States. Previous literature has suggested the pediatric population may constitute up to 40% of skiing-related injuries.
PURPOSE
To assess injury trends and the underlying mechanisms of skiing injuries in pediatric patients seen at emergency departments in the United States.
STUDY DESIGN
Descriptive epidemiology study.
METHODS
The National Electronic Injury Surveillance System (NEISS) was queried for pediatric (age ≤18 years) skiing injuries between January 1, 2012, and December 31, 2022. Injury mechanism, location, disposition, and diagnosis were recorded, and the statistical sample weight assigned by NEISS by hospital was used to calculate national estimates (NEs). Injury trends were evaluated with linear regression analysis.
RESULTS
Overall, 2951 pediatric skiing injuries were included (NE = 123,386). The mean age of the patients was 12.4 ± 3.5 years, with 61.3% of the injuries occurring in male patients. Impact with the ground was the most common injury mechanism (NE = 87,407; 70.8%). Fractures were the most common diagnosis (NE = 38,527, 31.2%), followed by strains/sprains (NE = 22,562, 18.3%), contusions/abrasions (NE = 16,257, 13.2%), and concussions (NE = 12,449, 10.1%). The lower leg was the most common fracture site (NE = 9509, 24.7%), followed by the shoulder (NE = 7131, 18.5%) and lower arm (NE = 5876, 15.3%). Analysis of annual injuries revealed no significant trend between 2012 and 2022 ( = .17), with fluctuations apparent throughout the study period. Significant decreases were seen in strains/sprains ( < .01) and contusions/abrasions ( < .01), but not in concussions ( = .57) or fractures ( = .70).
CONCLUSION
Impacts with the snow/ground made up 70.8% of all injuries. Fractures were the most common injury diagnosis, followed by strains/sprains, with the lower leg being most frequently fractured. While strains/sprains and contusions/abrasions showed a significant decline, there were no significant trends in fractures and concussions between 2012 and 2022.

INTRODUCTION
Pan-labral tears, commonly associated with recurrent shoulder dislocations, are a well-documented pathology. However, circumferential pan-labral tears following a first-time shoulder dislocation represent a rare and scarcely reported entity in the literature. Accurate diagnosis requires a comprehensive clinical history, physical examination, and further evaluation, often involving MRI. Even with advanced imaging, the acute nature of the injury can lead to the oversight of pan-labral tears, necessitating arthroscopic assessment for definitive diagnosis. Repairing such extensive glenoid labral tears presents a challenging task, requiring skilled surgeons to utilize accessory portals and percutaneous techniques for optimal visualization and anchor placement trajectory. To the best of our knowledge, this case report represents the first documentation of a pan-labral tear associated with a 1st-time shoulder dislocation.
CASE REPORT
A 27-year-old Asian male presented with pain and limited range of motion in the left shoulder following a single episode of anterior shoulder dislocation during cricket. Initial X-rays were unremarkable, but subsequent MRI revealed an anteroinferior labral tear with intact rotator cuffs. Arthroscopic evaluation disclosed a pan-labral tear, prompting meticulous repair under general and locoregional anesthesia. The patient achieved full recovery postoperatively.
CONCLUSION
While pan-labral tears are typically linked to recurrent dislocations, this case underscores their occurrence in a 1st-time traumatic shoulder dislocation without overt clinical signs or fractures. Arthroscopic repair demands careful intraoperative planning to achieve optimal tensioning and alignment of labral and capsular tissues. This report contributes to the limited literature on pan-labral tears associated with initial shoulder dislocations, emphasizing the importance of arthroscopic evaluation for accurate diagnosis and successful repair.

INTRODUCTION
The aim of this study was to investigate whether surgery with a 10 mm approach for volar locking plate fixation provides equivalent early post-operative outcomes to conventional incision surgery for distal radius fractures.
MATERIALS AND METHODS
The subjects were divided into a conventional incision group (mean age: 59.1 years, 8 males and 23 females) and a 10 mm approach group (mean age: 59.9 years of age, 6 males and 20 females). The wrist range of motion; grip strength; visual analog scale (VAS); quick disabilities of the arm, shoulder, and hand (Q-DASH) score; and modified Mayo score were assessed at 3 months after surgery. In addition, radial inclination, ulnar variance, and volar tilt were evaluated on post-operative radiography.
RESULTS
There was no significant difference between the groups in the wrist range of motion, grip strength, VAS, Q-DASH score, modified Mayo wrist score, and three parameters of post-operative radiography. All patients in both groups had no complications during the perioperative period.
CONCLUSION
We found that a 10 mm approach obtained early post-operative outcomes and alignment comparable to conventional incision surgery for patients with dorsal displaced distal radius fractures.

INTRODUCTION
Reverse total shoulder arthroplasty (RTSA) has revolutionized the treatment landscape for a spectrum of shoulder pathologies, extending its indications from rotator cuff arthropathy to encompass irreparable rotator cuff lesions, fractures, inflammatory arthritis, and tumors. However, the exponential increase in RTSA usage has brought a proportional rise in associated complications, with dislocation being one of the most common early post-operative complications.
CASE REPORT
This case report details a 65-year-old right-hand dominant male patient presenting with chronic pain and weakness in the right shoulder, diagnosed with advanced glenohumeral arthritis and massive irreparable rotator cuff tears. The patient underwent a Bony Increased- Offset RTSA (BIO-RTSA) procedure, coupled with subscapularis repair. Postoperatively, the patient experienced pain and instability, culminating in an atraumatic anterior dislocation at 4 months. Despite conservative management, recurrent dislocations persisted. Revision surgery was performed with an increase in the linear component size for containment. About 1 year postoperative of the revision surgery, recurrent dislocation reoccurred. Re-revision surgery was performed with secondary pectoralis major (PM) transfer for subscapularis deficiency due to re-tear from recurrent dislocation, and with an increased humeral tray size for better containment. About 1-year and 6-month post-operative to the re-revision surgery, the patient achieved restored stability, improved range of motion, and reported satisfaction with the outcome.
CONCLUSION
This case report underscores the challenges of managing recurrent anterior dislocation after RTSA. The successful use of secondary PM transfer highlights its efficacy as a salvage procedure in restoring stability for persistent anterior dislocation after RTSA. Yet, further clinical studies are warranted to establish the role of such interventions in the management for RTSA-associated complications.

INTRODUCTION
Osteonecrosis (ON) of the humeral head is defined as "avascular" when the death of bone is due to a disrupted blood supply. It is a known complication following proximal humeral fractures and can lead to poor long-term outcomes and even additional revision surgeries.
CASE REPORT
Patient AP developed symptomatic ON, 3 years following repair of a 4-part valgus impacted proximal humerus fracture. The point of interest in this case is the length of time from injury at which she developed symptomatic ON. Following surgical repair, she was seen at standard intervals, 6 weeks, 3-, 6-, and 12- month follow-ups and demonstrated an excellent recovery. By the 1 year follow-up appointment, she had obtained a range of motion in her left shoulder of 170° forward elevation and 60° in external rotation. At this point, she was able to discontinue physical therapy and was radiographically and clinically healed. However, 2 years after, she began experiencing sudden onset of pain with shoulder ROM and progressive limitation. She was diagnosed with an ON of her proximal humerus. The patient was prescribed a 3-month course of corticosteroid, 3 months following her operation for a gynecological-related issue. However, with strong progress being made 9 months after this prescription, and problems occurring over 2 years after taking the medication, it is unclear whether the ON was related to her fracture pattern or developed as a result of the corticosteroid usage or a combination of the 2 due to a "double hit."
CONCLUSION
This case review points out the potential need for continued monitoring even after radiographic and clinical healing is achieved in these injuries.

Early to Mid-term Results of Coracoclavicular Ligament Reconstruction Using the Infinity-Lock Button System in the Management of Traumatic Acromioclavicular Joint Dislocations and Lateral End of Clavicle Fractures.
Background The management of distal clavicle injuries with disruption of the coracoclavicular ligaments (CCLs) is challenging. The aim of this study was to assess the functional results of reconstructing the CCLs with the Infinity-Lock Button System using validated outcome measures, patient satisfaction scores, return to pre-injury activity, and complications. Methods A total of 28 cases of CCL disruption were assessed over a seven-year period, which included 14 lateral end-of-clavicle fractures and 14 acromioclavicular joint (ACJ) dislocations. All patients underwent stabilisation of the CCLs using the Infinity-Lock Button System. Patients were assessed preoperatively and postoperatively using validated outcome measures such as visual analogue scale (VAS), Oxford Shoulder Score (OSS), Quick Disabilities of Arm, Shoulder & Hand (Q-DASH) scores, return to pre-injury level of activities, patient satisfaction scores, and complications were reviewed. Results The mean age of patients was 36.7 years (18-74 years). The mean follow-up was 38.6 months (8-68 months). The mean time to surgery was 75.8 days (3-619 days). There was a statistically significant improvement in postoperative VAS, OSS, and Q-DASH scores compared to the preoperative (p-value <0.001). Out of the 28 participants, 23 (82.1%) returned to pre-injury level of activities, 25 (89.7%) reported 'good' or 'excellent' outcomes following the intervention, and none of the patients reported functional instability postoperatively. None of the patients required revision surgery or implant removal. Conclusion CCL reconstruction is vital in the management of clavicular injuries. This study demonstrates the safe use of the Infinity-Lock Button System in these injuries with statistically significant improvement in early patient-reported outcome measures, return to pre-injury level of activities, and subjective patient satisfaction.

Journal of Hand Surgery Global Online Mar 2024This review aimed to compare the postoperative outcomes of open reduction internal fixation (ORIF) versus excision in the surgical treatment of hook of hamate fractures.
PURPOSE
This review aimed to compare the postoperative outcomes of open reduction internal fixation (ORIF) versus excision in the surgical treatment of hook of hamate fractures.
METHODS
A systematic review of PubMed and EMBASE databases from 1954 to 2023 was performed using the search term "hook of hamate fracture" to identify all publications regarding the use of ORIF or excision in the treatment of hook of hamate fractures. Outcomes included a return to sport, pain, ulnar nerve dysfunction, flexor tendon dysfunction, union rate, wrist range of motion (ROM; % of contralateral hand), grip strength (% of contralateral hand), and quick disabilities of arm, shoulder, and hand scores.
RESULTS
Twenty-seven of the 705 total screened articles were included. Excision of the hook of hamate ( = 779) resulted in a shorter return to sport time (6 vs 7.8 weeks), lower rates of postoperative pain (6.1% vs 33.3%), higher rates of ulnar nerve sensory dysfunction (4.2% vs 0%), and higher rates of ulnar nerve motor dysfunction (1.5% vs 0%) relative to ORIF ( = 51). Chronic fractures had a longer return to sport time (7.2 vs 5.7 weeks) relative to nonchronic injuries.
CONCLUSIONS
Both surgical procedures appear to yield acceptable outcomes in the treatment of hook of hamate fractures. However, based on the sparsity of available data, we are unable to determine a consistent difference between hook of hamate excision and ORIF.
CLINICAL RELEVANCE
To our knowledge, no current consensus on the optimal surgical treatment for hook of hamate fractures exists. Our findings emphasize the need for a large prospective cohort study using standardized outcomes to provide strong evidence as to whether surgical excision or ORIF yields greater outcomes in the treatment of hook of hamate fractures.

Displaced fractures of the glenoid require surgical fixation. This poses multiple problems, including a difficult approach and achieving adequate reduction with current implants. We provide a surgical technical tip for fixing scapula neck and glenoid rim fractures with an Acu-Loc distal radius plate (Acumed, Weyhill, UK), illustrated with two recent case reports. Here, we present two cases of a 58-year-old female and a 51-year-old male presenting to a hospital following a fall, both sustaining an isolated right glenoid intra-articular fracture evident on plain radiographs. CT scans revealed a displaced and fragmented glenoid surface. A reverse Judet posterior approach facilitated exposure to enable the reduction of the glenoid, an uncommon approach. Current plate designs provide surgeons with limited options to fix complex fractures of the scapula and were not suitable here. The lateral scapula border and inferior glenoid have a similar anatomical shape to the distal radius. An Acu-Loc locking distal radius plate with a radial styloid plate was trialled and provided a good reduction to the fragmented glenoid. A distal radius plate can be a useful option to consider in complex scapula neck and glenoid rim fractures. A better understanding of glenoid shape will facilitate the further development of orthopaedic implants. Familiarity with various surgical approaches is needed to operate on these complex fractures.

Background The introduction of locking plate technology has improved the feasibility of distal radius fracture fixation without the need for bone grafting, yet challenges persist in cases of severely comminuted fractures and small, unstable intra-articular fragments. This study aimed to assess the outcomes of bone grafting in severely comminuted distal radius fractures treated with locking plates. Methods We performed a retrospective analysis involving 450 patients who underwent distal radius fracture fixations. We evaluated wrist motion, grip strength, and radiographic parameters, including radial inclination, radial tilt, ulnar variance, articular step, and fracture union at standardized intervals. In addition, at the 12- and 24-month marks, we assessed the disabilities of the arm, shoulder, and hand (DASH) questionnaire score. Results Out of the 450 patients who underwent distal radius fracture fixation using volar locking plate systems, 59 individuals (13%) required either autologous bone graft (n = 24) or synthetic bone substitutes (n = 35). In the final follow-up, all fractures had successfully united, displaying an average volar tilt of 4°, radial inclination of 18.8°, and an articular step or gap of 0.1 mm. Conclusion There was no significant difference between the use of autologous or synthetic bone grafts on clinical or radiological outcomes in the long term. Bone grafts are useful in severe metaphyseal comminution and aid in the reduction of articular fragments and bi-cortical comminution.
