BACKGROUND: Several studies have reported the clinical outcomes of medial ulnar collateral ligament (MUCL) reconstruction of the elbow joint in throwing athletes, including the rate of return to sports. However, little has been known about the imaging outcomes after MUCL reconstruction. The aim of this study is to report the clinical and imaging outcomes after MUCL reconstruction using figure of eight fashion in the elite and professional baseball players. METHODS: This study included 17 baseball players, who underwent MUCL reconstruction between July 2007 and May 2010. The average follow-up period was 48.6 months. Imaging assessment consisted of preoperative plain and stress radiographs, magnetic resonance imaging, and postoperative serial ultrasonography. The clinical assessments were composed of visual analogue scale (VAS) for pain, range of motion, and the Conway scale. RESULTS: The mean VAS score was 6.4 (range, 3 to 8) preoperatively and 2.2 (range, 0 to 4) postoperatively (p < 0.05). There were nine players (53%) classified as excellent who returned to sports at the same or higher level compared to preinjury. Serial ultrasonography revealed well-maintained grafts at 3 and 12 months in all of the players. Five out of 17 players showed decreased echogenecity in the common flexor tendon at 3 months, which was considered as remaining tissue swelling and resolved completely at 12 months. CONCLUSIONS: All grafts are well-maintained until 12-months based on the ultrasonographic findings, although only 53% of the players returned to preinjury level.

BackgroundHand injuries are very common in sports, such as skiing and ball sports. One of the major reasons causing hand and finger deformity is due to ligament and tendon injury. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) can demonstrate the complex anatomy of the fingers and thumb, especially the tendons and ligaments, and provide the accurate diagnosis of clinically important fingers and thumbs deformity due to ligamentous and tendinous injuries during sport activities.

MethodsSixteen fresh un-embalmed cadaveric hands were harvested from eight cadavers. A total of 20 healthy volunteers' hands and 44 patients with fingers or thumb deformity due to sports-related injuries were included in this study. All subjects had MR examination with T1-weighted images and proton density-weighted imaging with fat suppression (PD FS) in axial, coronal, and sagittal plane, respectively. Subsequently, all 16 cadaveric hands were sliced into 2-mm thick slab with a band saw (six in coronal plane, six in sagittal plane, and four in axial plane). The correlation of anatomic sections and the MRI characteristics of tendons of fingers and the ulnar collateral ligament (UCL) at the metacarpal phalangeal joint (MCPJ) of thumb between 20 healthy volunteers and 44 patients (confirmed by surgery) were analyzed.

ResultsThe normal ligaments and tendons in 16 cadaveric hands and 20 volunteers' hands showed uniform low-signal intensity on all the sequences of the MRI. Among 44 patients with tendinous and ligamentous injuries in the fingers or thumb, 12 cases with UCL injury at MCPJ of the thumb (Stener lesion = 8 and non-Stener lesion = 4), 6 cases with the central slip injury, 12 cases with terminal tendon injury, and 14 cases with flexor digitorum profundus injury. The ligaments and tendons disruption manifested as increased signal intensity and poor definition, discontinuity, and heterogeneous signal intensity of the involved ligaments and tendons.

ConclusionsSports injury-related fingers and thumb deformity are relatively common. MRI is an accurate method for evaluation of the anatomy and pathologic conditions of the fingers and thumb. It is a useful tool for accurate diagnosis of the sports-related ligaments and tendons injuries in hand.

According to literature reports, the injury rate of the athletes in Olympic Winter Games recent years was as high as 10%-14%. Combined with the background of corona virus disease 2019 (COVID-19), the medical insurance work of the 24th Olympic Winter Games held in Beijing had put forward more complicated requirements and more severe challenges. In order to better optimize anesthesia management, this article summarized the perioperative treatment of athletes in Olympic Winter Games, the safety protection strategy of medical staff under general anesthesia, and the potential impact of peri-operative drugs on athletes. Anesthesiologists, as the core members of the rescue team, should be familiar with the particularity of operative anesthesia of athletes, sum up relevant experience to ensure the safety of perioperative patients. So all kinds of technical measures should be taken in the process of operation to minimize the indoor pollution caused by the patient's cough. For example, all the patients should wear N95 masks from the ward to the operating room, and after the operation, wear the N95 masks back to the ward. Although the International Olympic Committee had banned more than 200 drugs for participants and athletes who had to strictly follow International Olympic Committee requirements during anesthesia, the athletes were no longer participating in this Olympic Winter Games, so opioids (sufentanil and remifentanil) and glucocorticoid (dexamethasone) could be used according to the actual needs of surgery and anesthesia. Five athletes in Yanqing competition area underwent surgical anesthesia in Peking University Third Hospital Yanqing Hospital. All the five patients received general anesthesia, of whom four underwent orthopaedic surgery and one underwent laparoscopic cholecystectomy. General anesthesia with laryngeal mask airway was the first choice in the five patients. And the pain after orthopaedic surgery was severe and nerve block technique could effectively relieve the pain after surgery. Three patients received ultrasound-guided nerve block analgesia, the postoperative analgesia lasted 36 h. After the operation, non-steroidal anti-inflammatory drug (NSAID) was infused intravenously in the ward and all the patients recovered uneventfully. As the core member of the trauma rescue team, anesthesiologists should be familiar with the particularity of the athletes' surgical anesthesia, do a good job in medical security, and summarize relevant experience to ensure the life safety of the perioperative patients.

BACKGROUND: We wanted to investigate acetabular labral tears and their correlation with femoroacetabular impingement in patients with sports injury. METHODS: Among 111 patients who were diagnosed with the acetabular labral tears after arthroscopic treatment from January 2004 to December 2007, we selected 41 patients with sports injury. There were 12 cases of Taekwondo injury, 5 of golf injury, 4 of soccer injury, 3 of gymnastics injury, 2 of Hapkido injury, 2 of aerobics injury, 2 of rock-climbing injury, 2 of fitness training injury and 9 of other sports injuries. We checked the subtypes of acetabular labral tears and the accompanying femoroacetabular impingement. For the cases with accompanying femoroacetabular impingement, we investigated the subtypes according to the types of sports, gender and age. At last follow-up, we checked the Harris Hip Score (HHS), the Hip Outcome Score (HOS) sports scale and the percentage of patients who returned to their sports activity. RESULTS: The average age of symptomatic onset was 26 years (range, 12 to 65 years). The ratio of males to females was 29 : 12. An average duration of the hip pain was 17 months (range, 1 to 60 months). The degenerative type of acetabular labral tears was the most prevalent with 32 cases (78%), and there were 9 cases (22%) of the partial tear type. Thirty cases (73%) were accompanied by femoroacetabular impingement. The average age of the 23 cases (56%) of the cam-type was 23 years (range, 12 to 48 years), and it was more likely to occur in men (87%) and for people practicing martial arts such as Taekwondo or Hapkido. An average age of the 5 cases (12%) of the pincer-type was 26 (range, 16 to 43 years), it usually occurred in women (60%) and for non-martial arts such as golf and gymnastics. There were 2 cases of the mixed type (cam + pincer-type). At 27 months follow-up, the HHS was 61 to 92 points, the HOS sports scale increased 43 to 75%, and the rate of returning to sports was 71%. CONCLUSIONS: In spite of the early expression of symptoms and the short duration of the acetabular labral tears, the high rate of degenerative acetabular labral tears in sports patients is likely associated with repetitive injury after the expression of symptoms. Femoroacetabular impingement in sports patients is seemed to be a cause of the early occurrence of acetabular labral tears. Because the possibility of acetabular labral tears is high in femoroacetabular impingement, sports patients may need to undergo early screening for the diagnosis and care of femoroacetabular impingement.

INTRODUCTIONIt is difficult to counsel the anterior cruciate ligament (ACL) deficient patient considering surgical reconstruction on the likelihood of eventual return to sports as information on this is lacking, especially in the Asian context. We wanted to determine how many of our patients who had ACL surgery returned to their previous levels of sports, 5 years after their surgery. For those that had not returned to their previous levels of sports, we wanted to identify their reasons for not doing so.

MATERIALS AND METHODSBased on our inclusion criteria of a minimum 5-year follow-up after primary ACL reconstruction, 146 patients were identified for assessment. Sixty-four patients were successfully recalled. The mean age of our patients was 24.8 years (range, 18 to 40). The patients completed the Lysholm Knee, Tegner activity and the Subjective International Knee Documentation Committee (IKDC) questionnaires. Clinical examination of the operated knee was performed according to the Objective IKDC evaluation form and with a KT-1000 arthrometer.

RESULTSThe mean Lysholm score was 85.2 and the mean subjective IKDC score was 79.5. 81.2% of our patients had normal or nearly normal knees (IKDC A or B) with the remaining 18.8% at IKDC grade C. The mean side-side difference for anterior translation using the KT-1000 arthrometer was 1.2 mm. The median pre-injury Tegner activity level was 7 and the median 5-year post-surgery Tegner activity level was 6. Nineteen patients did not return to their pre-injury sports levels because of social reasons and were excluded. From the remaining 45 patients, 28 patients (62.2%) returned to their previous level of sports and 17 patients (28.8%) did not return to their previous level of sports. Of whom, 9 (20%) said that they did not return due to fear of re-injury and the remaining 8 (17.8%) said they had not returned because of knee instability and pain. At 5 years, the subgroup of patients who had returned to sport had the best scores: Lysholm (88.5), subjective IKDC (84.6) and IKDC Grade A&B (89.3%). When we compared this with the subgroups that did not return to sport because of fear of re-injury and because of an unstable knee, we found that the difference in knee outcome scores between these 3 groups were statistically significant.

CONCLUSIONSixty-two per cent of our patients returned to their previous level of sport at 5 years after ACL reconstruction. Fear of reinjury is an important psychological factor for these patients not returning to sports. Our results would allow the attending surgeon to counsel the ACL deficient patient who is considering surgical reconstruction the likelihood of eventual return to sports.

Apophyseal injuries of the pelvis have increased recently with increased participation of teenagers in contact sports. Apophyseal fractures of the pelvis should be ruled out from apophysitis, os acetabuli and bony tumors. We report a case of fracture of anterior-inferior iliac spine following indirect injury to the hip in a young football player. The patient failed to get better with nonoperative management and continued to have pain in the left hip and signs and symptoms of impingement. He improved following surgical excision of the heterotopic bone and did not have any evidence of recurrence at 2 years follow- up.

BACKGROUND: The aim of this study was to identify the factors that affect the progress of a traumatic anterior dislocation of the shoulder. METHODS: Two hundred and thirty-eight patients (246 shoulders) with a traumatic anterior dislocation were enrolled in this study. The mean age at the time of surgery was 25 years (range, 14 to 47 years). There were 214 men and 24 women. RESULTS: One hundred and sixty-four shoulders (67%) were younger than 20 years at the time of the first dislocation. Patients younger than 20 years showed a shorter interval of redislocation (p = 0.001) and a higher frequency of dislocation (p = 0.001). Athletic patients experienced their first dislocation at a younger age (p = 0.023) and showed a shorter interval of redislocation (p = 0.001) than their non-athetic counterparts. The incidence of classic and non-classic Bankart lesions was unaffected by age at the time of the first dislocation, interval between the first and second dislocation or the frequency of dislocation. Patients with bony Bankart lesions had a higher frequency of dislocation (p = 0.043). CONCLUSIONS: The age at the time of the first dislocation and athletic activity were related to early redislocation and a high frequency of dislocation. Bony Bankart lesions were observed more often in patients with a higher frequency of dislocation. Early surgical treatment is a good option for young athletic patients with a bony Bankart lesion and a short interval between the first and second dislocation.

INTRODUCTIONSpiral and oblique fractures of distal 1/3 of tibia-fibula are relatively common fractures of long bones. Due to their types, aetiology, limited coverage and blood supply, these fractures often lead to union and soft tissue problems.

MATERIALS AND METHODSTwenty-seven patients with spiral and oblique fractures of distal 1/3 of tibia-fibula were treated with circular external fixator (CEF) between January 1997 and August 2000. All the fractures were closed. The type of fractures based on AO classification were A1 (n = 8), A2 (n = 6), B1 (n = 11) and C1 (n = 2).

RESULTSThe mean framing time was 14.1 +/- 1.8 weeks (range, 12 to 19 weeks), and the mean treatment time was 18.8 +/- 2.2 weeks (range, 15 to 24 weeks). The patients were followed up for 36 to 78 months (mean follow-up time: 51.9 +/- 10.4 months). The results were evaluated for shortness, angulation, rotation, ankle stiffness, pain and infection. After removal of the frames, 11 patients had ankle pain and stiffness, and 3 patients had loss of range of motion in the ankle even after rehabilitation. None of the patients suffered any complications such as shortness, angulation, rotational deformity and infection, and none had loss of motion in the knee.

CONCLUSIONSCEF might be a preferable alternative treatment for distal tibia-fibula fractures due to its easy application, fewer major complications such as shortness and angulation, early mobilisation and shorter treatment time.
