Parsonage-Turner syndrome, affecting suprascapular nerve and especially to infraspinatus muscles after COVID-19 vaccination in a professional wrestler, a case report and literature review of causes and treatments.

BACKGROUND: Acute peripheral neuropathy, also known as Parsonage-Turner syndrome or neuralgic amyotrophy, mostly affects the upper brachial plexus trunks, which include the shoulder girdle. It is typically accompanied by abrupt, intense pain, weakness, and sensory disruption. The etiology and causes of this disease are still unknown because of its low prevalence, however viral reactions-induced inflammation is one of its frequent causes. CASE PRESENTATION: Here, we introduce a professional wrestler patient who was diagnosed with PTS after vaccination and was treated, and we review some articles in this field. CONCLUSION: When it comes to shoulder-girdle complaints and pain, Parsonage-Turner syndrome can be a differential diagnosis. Corticosteroids during the acute period, followed by physical therapy, appear to be an efficient way to manage pain, inflammation, muscular atrophy, and the process of recovering to full nerve regeneration.

The Effect of Lower Limb Position on Anterior Cruciate Ligament Reconstruction on Uncommon Complications after Surgery.

Background: To reduce the complications of orthopedic surgery, the desire for less invasive procedures, such as, knee arthroscopy to repair the anterior cruciate ligament, has increased. There are, currently, two common positions for limbs that are used during surgery depending on the surgeon's experience. Therefore, our aim was to investigate the effect of limb position on complications after anterior cruciate ligament reconstruction surgery. Materials and Methods: From April 2016 to July 2020 at our orthopedic-sports trauma center, 688 patients between the ages of 18 and 50 with anterior cruciate ligament rupture underwent reconstruction surgery with a hamstring graft. Patients were divided into two groups in terms of limb position at the time of surgery. For three months, patients were evaluated for surgical complications, basic demographic information, and information during surgery. Results: There was no statistically significant difference between the two groups in terms of demographic information, side of injury, preparation time, tourniquet time, operation time, and duration of hospitalization. At quarterly follow-up, there was no significant difference between the two groups in terms of postoperative complications (P = 0.976). Conclusions: There is no difference between compartment syndrome and deep vein thrombosis in different situations, therefore, the surgeon should operate in any position he is skilled in. Also, surgeons should always pay special attention to these complications and provide necessary training to patients in order to prevent them.

Comparison of the Effectiveness of Two Management Strategies in the Pandemic COVID-19 Period in Patient Visits (Face-to-Face Visits vs. a Smartphone) in follow-up the Range of Motion of the Knee in Patients with Anterior Cruciate Ligament Reconstruction.

Background: As the prevalence of the coronavirus increases, there is now more emphasis on reducing "face-to-face" patient visits. Therefore, the use of smartphones and their special medical applications can play an important role in following up patients. The aim of this study was to evaluate the use of smartphone in evaluating clinical outcomes and range of motion (ROM) of patients after anterior cruciate ligament reconstruction (ACLR). Materials and Methods: From January to December 2020, 112 patients between 20 and 50 years old were randomly selected at our orthopedic sports center. All patients were visited online through smartphone by a knee fellowship surgeon in the morning (case group) and again all of them were visited online through smartphone in the evening by another knee fellowship surgeon (control group). Both visits were done at regular intervals in the 2nd, 6th, and 12th week after surgery. Patients were evaluated for function outcomes and joint ROM. Results: The two groups were similar in terms of mean International Knee Documentation Committee score, Lysholm knee score, and Tegner Knee Score and did not show statistically significant difference (P < 0.05) There was no significant difference in knee ROM measurements between the two groups (face-to-face visits and online through smartphone visits) during the follow-ups (P > 0.05). Conclusion: Smartphone apps are highly effective in assessing postoperative condition of knee ROM after ACLR, especially in the short time. However, this ability has been reduced in evaluating the long term. Hence, evaluation is still necessary through direct examination in the presence visit.

Biomechanical study of the abductor pollicis longus & extensor pollicis brevis after release and reconstruction of the first dorsal compartment of the wrist.

BACKGROUND: The purpose of this study was to determine the biomechanical changes after first dorsal compartment release and after Z-plasty of the first dorsal compartment with respect to the excursion and displacement of the abductor pollicis longus and extensor pollicis brevis tendons. MATERIALS AND METHODS: Six fresh frozen cadaveric hand and forearms were obtained and the tendons of the abductor were exposed and separated from surrounding tissues through a palmar incision and tenotomized at the musculotendinous junction. The excursion and displacement of the abductor pollicis brevis and flexor pollicis brevis tendons were measured for all six cadaveric hands. RESULTS: Increases in tendon excursion were observed in both the abductor pollicis longus (29%) and extensor pollicis brevis (30%) while these observations after Z-plasty were 0.04% for abductor pollicis longus and 0.07% for extensor pollicis brevis. With the use of the modified Elftman curve for the Lengths, tension relationship and Brand's data for resting fiber length we found that 1 cm increase of The excursion of the APL and EPB will decrease tension %65 and %80 respectively. There was also a 12.2-mm displacement of the tendons after release and 4.8 mm displacement after z-plasty of the compartment. CONCLUSION: It seems that Procedures such as enlargement plasty of Kapandji or Z-plasty will increase the size of the compartment but will not change the biomechanical behaviors of the tendons significantly.

Results of surgical treatment for Sprengle's deformity with vertical corrective scapular osteotomy.

INTRODUCTION: Sprengle deformity is the most common congential anomaly of shoulder complex that is the result of scapular placement in cephalad abnormal position. The purpose of this study is the evaluation of clinical and radiological results of vertical corrective scapular osteotomy and comparision of these results with previous studies. METHODS: We retrospectively reviewed the results of the vertical corrective scapular osteotomy (VSO) with or without clavicular osteotomy and wake-up test in 31 consecutive patients at an average duration of follow up of 30 month (6 month-15 years). 22 patients were girls and 9 were boys. The average age of the patients was 7.3 years (3-13) at the time of surgery. We evaluated the clinical and radiological results of this method in last fallow-up. No funding was used for this study and there are no conflicts of interest. RESULTS: 31 surgical procedures were performed. All osteotomies were healed. No neurovascular complication. Postoperative the mean shoulder flexion and abduction were improved 30 and 36° respectively (p < 0.001). The mean improvement of superior scapular angle (S.S.A) and inferior scapular angle (I.S.A) were 16 and 21° respectively (p < 0.001). CONCLUSION: It is intuitive that more cosmetic scapular lowering with little chance of neurovascular problems can be achieved after VSO. In addition, scapular rotation can be corrected using this technique, which should be considered as one of the advantages of this technique.We believe that a properly applied VSO procedure in severe deformities is safe with predictable outcomes in the treatment of a complex deformity that provides favorable functional and cosmetic outcomes in the longer term.

Osteochondral autograft transfer (mosaicplasty) for treatment of patients with osteochondral lesions of talus.

PURPOSE: Osteochondral lesion of talus (OLT) is one of the common causes of ankle pain. This disorder is common in young athletes after ankle injury. There are various therapeutic options. One of the options is mosaic plasticizer. The purpose of this study was to investigate the effect of mosaicplasty on improvement of symptoms of patients with osteochondral lesions of talus. METHODS: Nineteen patients with osteochondral lesions of talus participated in this study, who were treated with mosaicplasty. Before and after treatment, pain (visual analogue scale), function (American Orthopaedic Foot and Ankle Society), range of motion and radiographic signs were evaluated. RESULTS: The results of this study showed that mosaicplasty could significantly reduce pain, increase function and improve radiographic symptoms. The range of motion increased after treatment, which was not significant. CONCLUSION: We can confirm the effect of mosaicplasty on the improvement of patients with osteochondral lesions of the ankle, suggesting it as a treatment option.

Clinical and functional results of radial club hand with centralization and pollicization using the second metacarpus: A clinical case series.

INTRODUCTION: Radial club hand (RCH) is a rare congenital deformity leading in several functional and psychological problems. However, our knowledge about the long-term functional outcomes of treating RCH is limited. In current study, we investigated the outcomes of centralization and pollicization using second or third metacarpal bone in RCH patients. METHODS: There were 15 hands (13 patients) with RCH underwent centralization and pollicization using second or third metacarpal bone or tendon transfer. The patients aged 1.2 ±â€¯1 years at the time of the surgery. On early postoperative x-rays, the forearm-hand angle was measured. The patients were followed for 6.2 ±â€¯2.3 years. At the final visit, disabilities of arm, shoulder and hand (DASH) score was completed. Furthermore, forearm-hand angle and range of motion of both wrists in sagittal and coronal planes were measured. RESULTS: The mean of forearm-hand angle increased significantly. In 11 wrists, forearm-hand angle increased only 10 degrees of less. The range of operated wrist was improved in sagittal and coronal planes. The relative range of wrist motion in patients with unilateral deformity in sagittal and coronal planes was 83 ±â€¯11 percent and 61 ±â€¯12 percent. Three patients developed skin necrosis. CONCLUSION: Early centralization and pollicization using second or third metacarpal bone can significantly restore the range of motion and function in patients with RCH.

Treatment of Massive Irreparable Rotator Cuff Tear with Arthroscopic Subacromial Bursectomy, Biceps tenotomy, and Tuberoplasty.

BACKGROUND: The alternative surgery for massive and irreparable shoulder rotator cuff tears in older patients is the debridement of subacromial bursa, biceps tenotomy, and tuberoplasty (reverse acromioplasty). This study aimed to report the effectiveness of such a treatment performed arthroscopically in a small group of patients for a short period of time. METHODS: This prospective study was conducted on 12 patients with massive irreparable rotator cuff tear during 2014-2017. Participants with the mean age of 65 were subjected to arthroscopic debridement of subacromial bursa, necrotic rotator cuff tendon remnants, and tuberoplasty without coracoacromial ligament excision. The sign and symptoms of patients before and after the surgery were evaluated based on Modified-University of California at Los Angeles (UCLA) Shoulder Score. RESULTS: With the mean follow-up of 18 months (12-24 months), the mean of the modified UCLA score improved from 9.2 to 27.5. The obtained results of the study revealed that the pain and range of motion improved to near normal in the participants. The functional outcome was good although there were a decrease of acromiohumeral distance from 5 to 4 mm and a slight increase in degenerative changes. CONCLUSION: This simple arthroscopic procedure is recommended for massive irreparable rotator cuff tear, especially in elderly patients. LEVEL OF EVIDENCE: IV.

Modified Internal Fixation Technique for Acromio-Clavicular (AC) joint dislocation: The "Hidden Knot Technique".

Acromioclavicular (AC) joint injuries are common and often seen in contact athletes, resulting from a fall on the shoulder tip with adducted arm. This joint is stabilized by both static and dynamic structures including the coracoclavicular (CC) ligament. Most reconstruction techniques focus on CC ligament augmentation as the primary stabilizer of the AC joint. The best surgical technique for some AC joint dislocations is still controversial. In this study, we explained a modification of the CC ligament reconstruction technique described by Wellmann. The method is based on minimally invasive CC ligament augmentation with a flip button/polydioxanone (PDS) repair, typically used for extracortical ACL graft fixation. Patients commonly complain that heavy sutures under the skin in subcutaneous tissue irritate the skin and sometimes require reoperation for suture removal. We present an augmentation technique that resolves this issue by changing the suture knot location to the sub-clavicular position. Level of evidence: II.

Repair of Massive and Irreparable Rotator Cuff Tear Using Arthroscopic Method.

Rotator cuff tear stands as one of the major origins of shoulder discomfort and disability, especially in elderly patients over 60 years. Improvement of performance and reduction of pain hardly occur in patients with contracted rotator cuff tear. Despite therapeutic advances, yet there are many discussions over choosing the best type of treatment for major rotator cuff tear. Complete care of massive rotator cuff tear continues to be a challenge in shoulder surgery. Treatment options have changed in comparison with traditional treatment methods in open or arthroscopic debridement surgery with or without decompression. Recently, many treatments have been introduced, including a range of non-surgical treatments, acromioplasty by debridement, minor repair biceps tenotomy, tuberoplasty by biceps tenotomy, minor repair, mini-open rotator cuff repair, arthroscopic rotator cuff, muscle movement, reverse shoulder arthroscopy, soft tissue reinforcement and hemiarthroplasty. Non-surgical massive rotator cuff control is typically assigned for patients with insignificant pain. This therapy functions by changing activities, proper use of steroid injections and physical therapy with an emphasis on the anterior deltoid exercises. But the main problem is the selection of the best treatment and making the final decision. In general, in the arthroscopic, morbidity, postoperative pain along with hospital stay are less and the operation has better cosmetic results. So this information and our results have prompted us to study a variety of rotator cuff treatment methods with a focus on the arthroscopic treatment.

Clinical Results of Platelet-Rich Plasma for Partial Thickness Rotator Cuff Tears: A Case Series.

Partial thickness rotator cuff tears (PTRCTs) are a common pathology among shoulder disorders in people over 50 years. Treatment of PTRCTs remains controversial. Most studies on the treatment of PTRCTs have explained surgical techniques or outcomes; few studies have centralized on the conservative and new management of PTRCTs, like treatment with Platelet-rich plasma (PRP). These case series study have been conducted on Platelet-rich plasma (PRP) injection, as a concentrated source of cytokines that can stimulate healing of soft tissue. PRP injection showed positive effect on improving PTRCTs complains. This method improved pain, function, DASH score and shoulder joint range motion in. Because of PRP products are safe and easy to prepare and apply, and also according to improving patient's condition, this method can be used to treat PTRCTs.

Wound dehiscence after total knee arthroplasty.

INTRODUCTION: Wound dehiscence is one of the most common complications of surgical ulcer, involving the breaking open of the surgical incision along the stitch. This condition is a severe complication of total knee arthroplasty. PRESENTATION OF CASE: We report a case of a 59-year-old female patient with diabetes who underwent a total knee arthroplasty in which all layers of wounds were dehiscence and prosthetic was exposed. DISCUSSION: Wound dehiscence is a complication after total knee arthroplasty especially in diabetic patient. So, patients with diabetes more susceptible to development of wound dehiscence following total knee arthroplasty and should be followed particularly postoperatively care. CONCLUSION: Postoperative care after knee replacement should be more considered in diabetic patients. Finally the patient was successfully treated with irrigation and debridement (I&D) and polyethylene insert exchange.

Loosening of Total Knee Arthroplasty after Brucellosis Infection: A Case Report.

In this report we describe a 78-year-old man whose total knee arthroplasty showed the symptoms of infection with brucella with radiographic signs of loosening 5 years after the index surgery. The patient was treated successfully after a 2-stage revision arthroplasty surgery along with using rifampicin and doxycycline for 8 weeks.

The Effect of Patellofemoral Pain Syndrome on Gait Parameters: A Literature Review.

Patellofemoral pain syndrome (PFPS) is one of the most frequent causes of anterior knee pain in adolescents and adults. This disorder can have a big effect on patients' ability and quality of life and gait. This review included all articles published during 1990 to 2016. An extensive literature search was performed in databases of Science Direct, Google Scholar, PubMed and ISI Web of Knowledge using OR, AND, NOT between the selected keywords. Finally, 16 articles were selected from final evaluation. In PFPS subjects, there was lower gait velocity, decreased cadence, and reduced knee extensor moment in the loading response and terminal stance, delayed peak rear foot eversion during gait and greater hip adduction compared to healthy subjects, while for hip rotation, there was controversy in studies. Changes in the walking patterns of PFPS subjects may be associated with the strategy used for the reduction of patellofemoral joint reaction force and pain.

Arthroscopic Bridge Technique for PCL Avulsion: Surgical Technique and Key Points.

This study describes all-arthroscopic fixation of the posterior cruciate ligament avulsion fracture using 'suture bridge technique'. We used this technique in 3 consecutive patients. All were satisfied and returned to the activities prior to injury. This technique can be considered as a safe and effective method for fixation of PCL avulsion, which allows active mobilization with lowered risk of complications.

Iranian Joint Registry (Iranian National Hip and Knee Arthroplasty Registry).

Periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries. In this article we introduce the methodology used for the foundation of the National Iranian Joint Registry (IJR) with a joint collaboration of the Social Security Organization (SSO) and academic research departments considering the requirements of the Iran's Ministry of Health and Education.

Platelet-Rich Plasma for Frozen Shoulder: A Case Report.

Frozen shoulder is a glenohumeral joint disorder that movement because of adhesion and the existence of fibrosis in the shoulder capsule. Platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. To date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. A 45-year-old man with shoulder adhesive capsulitis volunteered for this treatment. He underwent two consecutive platelet-rich plasma injections at the seventh and eighth month after initiation of symptoms. We measured pain, function, ROM by the visual analogue scale (VAS), scores from the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and goniometer; respectively. After first injection, the patient reported 60% improvement regarding diurnal shoulder pain, and no night pain. Also, two-fold improvement for ROM and more than 70% improvement for function were reported. This study suggests the use of platelet-rich plasma in frozen shoulder to be tested in randomized trials.

Arthroscopic posterior cruciate ligament reconstruction by using hamstring tendon autograft and transosseous screw fixation: minimal 3 years follow-up.

BACKGROUND: The aim of this trial is to prospectively evaluate the outcomes of PCL reconstruction by means of quadruple hamstring tendon autograft with a double-fixation method at minimal 3-year follow-up. MATERIALS AND METHODS: Only patients who underwent PCL reconstruction without any other concomitant injury were included in this study. A hamstring tendon graft is composed of a quadruple-stranded gracilis tendon and semitendinosus tendon about 10 cm in length. An arthroscopic technique via a two incision and a double-fixation method was applied. Clinical evaluations were performed for 52 patients. Clinical assessment of patients included the Lysholm knee scores, International Knee Documentation Committee (IKDC) scores, thigh muscle evaluation, and radiographic investigation. RESULTS: On the Lysholm knee score, 90 % of the patients displayed good or excellent rating in the final assessment. In the IKDC rating analyses, 60 % of the patients demonstrated 3-5-mm ligament laxity. For the IKDC final rating, 81 % were normal or nearly normal. Seventy-nine percent of the cases revealed less than a 10-mm difference in thigh girth between their reconstructed and contra lateral limbs. CONCLUSION: Arthroscopic PCL reconstruction using quadruple hamstring tendon autograft provides acceptable outcomes at a minimum 3-year follow-up. The four-stranded hamstring tendon graft is suitable in graft size and results in minimal harvesting morbidity. We recommend that quadruple hamstring tendon graft be chosen for PCL reconstruction to achieve good ligament reconstruction. A double-fixation method which has been applied in this trial can be used to provide rigid fixation.

Early clinical results of arthroscopic remplissage in patients with anterior shoulder instability with engaging hill-sachs lesion in iran.

BACKGROUND: To assess the outcome of the remplissage arthroscopic surgical method in patients with anterior shoulder dislocation associated with Hill-Sachs lesion. METHODS: Ten patients with anterior shoulder dislocations and Hill-Sachs lesions were entered into this study and were operated on by the remplissage arthroscopic surgical method. They were followed up 22 months after surgery in order to evaluate the outcome of the treatment, including recurrence of dislocation and motion limitation. RESULTS: During the internal follow up period, no case of recurrence was found. Motion limitation during the follow up period was not significant (internal rotation limitation=5°±1°, and external rotation limitation=4°±1°). CONCLUSIONS: Our findings suggest that the remplissage arthroscopic surgical method is an acceptable, safe and reliable treatment for anterior shoulder dislocation with engaging Hill-Sachs lesion.

Comparison of morphologic consequences of open and endoscopic carpal tunnel release.

OBJECTIVES: The objective of this study is to evaluate the carpal canal morphologic consequences following endoscopic carpal tunnel release compared with open approach. METHODS: 48 Patients with CTS were enrolled in our prospective trial. Participants were classified in 2 groups: 24 patients underwent open surgery technique and 24 underwent endoscopic carpal tunnel decompression. Carpal canal shape and volume, configuration and position of contents, were analyzed by using imaging techniques. RESULTS: Preoperative carpal canal volume in endoscopic patient group averaged 5.7±1.4 cc and 7.3±2.9 cc at 6 weeks postoperatively (28%±7%, p=0.018). In contrast preoperative carpal canal volume in open carpal tunnel release group averaged 4.9±1.1 cc (and increased to 6.2±1.7 cc at 6-week follow up investigation (36%±5%, p=0.002). Preoperative carpal arch width calculation in endoscopic carpal tunnel release group averaged 21.7±1.1mm and 21.5±1.9mm in open carpal tunnel release patients (p=0.6575). Postoperative carpal arch width measurements in endoscopic carpal tunnel decompression group averaged 22.6±4.1mm and 22.1±2.9mm in open carpal tunnel release patient population at 6-week follow-up investigation (p=0.628). CONCLUSION: Endoscopic approach causes an increment in carpal canal volume comparable to open technique and provides equivalent anatomic outcomes and will produce at least equivalent long-term clinical relief.
