Multiple Intraosseous Cysts of the Carpal Bones Presenting as Unilateral Carpal Tunnel Syndrome.

Intraosseous ganglion cysts (IGC) of the carpal bones are frequently reported in the literature, involving at most two carpal bones of the same wrist. Only one case recently described the presence of multiple intraosseous ganglion lesions in the capitate, lunate, and triquetrum, resulting in chronic wrist pain. The following study reports the first case of multiple IGCs causing a unilateral carpal tunnel syndrome (CTS), in a 56-year-old woman, with no previous history of trauma. Failure of conservative management prompted carpal tunnel release and the surgical excision of the ICGs, followed by autologous bone grafting to fill in the defects. Consequently, IGCs must be considered in the differential diagnosis of unilateral CTS due to the expansile nature of the bone lesions.

Intra-articular Lateral Tibial Plateau Osteoid Osteoma: Case Report and Arthroscopic Management.

Osteoid osteoma occurs in various locations in the human body, mostly in the metaphysis and diaphysis of long bones. This article describes a rare case of osteoid osteoma occurring in an intra-articular location, specifically in the lateral tibial plateau of a 40-year-old female patient. The challenge of diagnosing such a pathology in an atypical location was tackled in this article as well as different management options. Arthroscopic resection was opted in this case.

Atraumatic Isolated Stress Fracture of the Distal Tibial Metaphysis in a Pre-menopausal Patient: A Case Report.

Stress fractures are partial or complete bone fractures usually occurring in the weight-bearing bones resulting from repeated cycles of submaximal stress and bone remodeling. When the tibia is involved, it usually affects the proximal or middle third part of the bone. This pathology is most often seen in athletes or related to traumatic activities. This case describes a healthy, pre-menopausal, non-athlete woman presenting with a distal tibial atraumatic stress fracture. Diagnosis is usually confirmed by a CT scan or MRI since radiographs could often show no abnormalities. Treatment of such fractures is conservative in the majority of cases and when present, predisposing or causative factors should also be investigated and assessed.

Concomitant ipsilateral femoral neck and pelvic ring fractures in the setting of a low energy fall in an elderly patient: A case report.

INTRODUCTION: Simultaneous ipsilateral fractures of the femoral neck and pelvic ring secondary to low energy falls are an extremely rare occurrence. Consequently, there is no standardized protocol for the management of such injury. Only few other cases were reported in the literature. CASE PRESENTATION: A 94-year-old woman presented with a left sub-capital femoral neck fracture, associated with comminuted and displaced fractures of the left superior and inferior pubic rami, after sustaining a fall from height. A decision was made to treat the femoral neck fracture with a left uncemented hemiarthroplasty, while the pubic rami fractures were managed conservatively. DISCUSSION: Coexisting femoral neck and pubic rami fractures due to low energy trauma is newly emerging in literature. Consequently, an elderly patient falling from standing height might require a CT or an MRI to reach an accurate diagnosis of the resultant injuries. While hip fractures are almost always treated surgically, pelvic ring fractures are only managed invasively when the conservative approach fails. This creates a dilemma when both fractures occur simultaneously, as appropriate measures must be taken to treat the patient with lowest risk of complications. CONCLUSION: Low-energy fractures of the hip and pelvic ring should no longer be regarded as mutually exclusive. Any patient presenting with one of them should be investigated for the other. A consensus should be reached regarding the most appropriate technique to manage such injuries.

Ipsilateral Simultaneous Low-Energy Multiple Upper Limb Fractures in an Elderly Patient: Case Report and Review of the Literature.

Traumatic injuries of the upper limb can result in variant fracture combination. This article discusses a rare injury combination including ipsilateral proximal and distal humerus fractures alongside a distal radius fracture. The mechanism of the fall is unknown, but the patient being old with such a complex injury, one can only assume that osteoporosis played a major role. Open reduction and internal fixation was opted for the distal humerus and radius fractures, and percutaneous pinning was done for the proximal humerus fracture. Surgery is an option to each one of these injuries with different techniques available for managing such an association, with emphasis made on osteoporosis workup to help prevent such complex injuries.

Intertrochanteric fractures treated by diaphyseal support arthroplasty with hook plate vs cerclage wires only: A retrospective cohort study.

BACKGROUND: The treatment of unstable fractures of the intertrochanteric region of the hip in the elderly is controversial. Conventionally, internal fixation with intramedullary nail or a dynamic hip screw is the treatment of choice in intertrochanteric fractures. Nowadays, some authors encouraged the use hip arthroplasty for management of these fractures with good outcome. The aim of this study is to compare total hip arthroplasty with hook plate against total hip arthroplasty with cerclage cables in the management of unstable intertrochanteric fractures. MATERIALS AND METHODS: Out of 100 admitted patients to a central university hospital in Beirut between 2013 and 2019 with a diagnosis of unstable intertrochanteric fracture of the hip, only 64 (36 hook plate vs 28 cerclage) patients were selected. This is a retrospective study, patients were excluded if lost to follow up, or if follow up less than one year is available. The data were retrieved from inpatient and outpatient hospital files. Functional outcomes were assessed according to ambulatory capacity. The main clinical measures were early postoperative full weight bearing, postoperative complications, functional outcome and radiologic assessment done by a radiologist in addition to measuring the dysfunction via the Harris Hip Score. RESULTS: The time to full weight bearing, the rate of postoperative complications, radiologic outcome and the functional outcomes were more satisfactory in the hook - plate group than in the cerclage - cable group. CONCLUSION: According to the results, total hip arthroplasty with hook plate is considered the preferred modality of treatment in mobile elderly patients above sixty-five years of age with an unstable intertrochanteric femoral fracture, despite being a bulky foreign material that can lead to trochanteric bursitis.

Management of a Complex Supracondylar Periprosthetic Femur Fracture with Intramedullary Strut Allograft and Bilateral Locking Plates.

Supracondylar periprosthetic femoral fractures occurring above total knee replacements have been considered a rare entity. However, they continue to increase in frequency with the increasing number of arthroplasties and the improvement in morbidity and mortality in the concerned patient population. The management of periprosthetic distal femoral fractures is a challenging orthopedic problem. In this brief communication, a case of 49-year-old woman with rheumatoid arthritis who sustained a low distal comminuted periprosthetic femoral fracture is presented. Her fracture was eventually managed with an intramedullary fibular strut allograft and bilateral locking plate placement reaching satisfactory healing and restoration of alignment. The primary aim of this report is to provide insight into this novel technique as a successful alternative to other standard surgical options.

Shoulder Arthroscopic Rotator Cuff Repair With Biceps Tenodesis and Acromioplasty Using a Single Working Portal.

Rotator cuff repair, acromioplasty, and biceps tenodesis operations have become some of the most common shoulder surgical procedures, evolving from open techniques to minimally invasive arthroscopic techniques. The use of many arthroscopic portals has been associated with surgical risks to many surrounding anatomic structures. We present an arthroscopic technique using a single anterolateral working portal for rotator cuff repair, acromioplasty, distal clavicle excision, and long head of the biceps tenodesis; this technique decreases the risk of injury to the surrounding neurovascular and musculotendinous structures, enables a faster recovery, and is minimally invasive.

Modified Mitchell technique for treating hallux valgus: Retrospective case series on a Middle-Eastern population and literature review.

INTRODUCTION: The hallux valgus deformity is a complex deformity of the first ray of the foot, with more than 100 procedures developed for its treatment. The aim of this retrospective study was to assess the clinical and radiographic outcomes of a modified Mitchell's technique. METHODS: Between 2007 and 2018, 75 patients underwent the procedure. Clinical results were assessed by the AOFAS score. Radiological studies were evaluated by measuring pre-operative and post-operative HVA and IMA angles as well as the relative shortening of the first metatarsal. RESULTS: Of the initial 75 patients, 42 patients remained eligible with a total of 67 feet. The mean age and follow-up were 47.8 and 5.2 years respectively. Global AOFAS score improved from 45.3 to 88.8 (p < 0.01). Mean HVA and IMA improved from 37.0 to 10.2 (p < 0,01) and 12.1 to 5.6 (p < 0.01), respectively. The mean metatarsal shortening was 3.0 mm (p < 0.01). The statistical analysis showed no significant correlation between preoperative HVA and IMA angles with postoperative shortening, metatarsalgia, AOFAS scores nor the difference between the preoperative and postoperative AOFAS scores. CONCLUSION: Short- and long-term outcomes of this modified Mitchell's osteotomy have been reported. Compared to other studies, these modifications proved to result in very good clinical and radiological outcomes even in severe cases with HVA>40. It has shown to be reliable, reproducible, and cost-efficient with low complication rates. We would like to highlight the importance of proper patient selection, limited soft tissue stripping, and adherence to the proposed surgical steps to avoid unwanted complications.

Bilateral Reverse Total Shoulder Arthroplasty with Soft Tissue Release for Bilateral Posterior Fracture Dislocation after Status Epilepticus.

Proximal humerus fracture is a common orthopedic presentation, with bimodal age distribution. On the other hand, bilateral proximal humerus fracture dislocation is a rarely reported pathology, especially when it is not the result of direct trauma. We present a case of a 71-year-old female patient found to have simultaneous bilateral 4-part proximal humerus fractures following status epilepticus treated surgically with bilateral reverse shoulder arthroplasty with constraint and soft tissue release. In a patient with recurrent status epilepticus episodes, the combination of constrained reverse shoulder arthroplasty and the extensive soft tissue release should decrease the rate of failure and dislocation dramatically. We conclude, after reviewing the literature, that there is no straightforward algorithm for treating such patients and that a clear classification should take into account both bone quality and patient comorbidities which has yet to be developed.

Irreducible anterior shoulder dislocation with interposition of the lesser tuberosity and subscapularis.

Anterior shoulder dislocation is the most common joint dislocation, unreducible dislocations however are a rare occurrence. The causes of the irreducibility vary, with interposition of soft tissues or bony fragments within the glenohumeral joint being the usual culprits. We present the case of an irreducible anterior shoulder dislocation with concomitant greater and lesser tuberosity fractures, with interposition of the subscapularis and lesser tuberosity thereby preventing reduction. We present the case of a 54-year-old female presenting with a left shoulder fracture dislocation after a fall from a 1.8-meter ladder. Patient was taken to the operating room after undergoing a CT scan. Attempts of closed reduction after administration of general anesthesia were unsuccessful. Open reduction and internal fixation with plate and screws was done through a deltopectoral approach. Intra-operatively, the lesser tuberosity and the subscapularis were found to be the cause of the irreducibility of the dislocation. At the latest follow up at 6 months post-op, the patient had regained a normal ROM with a good function. The vast majority of shoulder fracture dislocations are easily reducible, with only a limited number of case reports discussing irreducible fracture-dislocations. The causes of the irreducibility comprise interposition of soft tissue or bony fragments within the glenohumeral joint such as avulsed labrum or tendons, glenoid or humeral bony fragments interposition, and tensioning of nerves or tendons such as the biceps or subscapularis around the humeral head. CT scans are in our opinion very important for proper surgical planning when needed and for possible identification of an irreducible dislocation. Orthopedic surgeons should be aware that difficult closed reductions of the glenohumeral joint, whenever encountered, should raise the possibility of interposition of bony fragments or soft tissues where surgical treatment might be mandatory.

All-Inside Anterior Cruciate Ligament Reconstruction With Augmentation Using the Native Anterior Cruciate Ligament Remnant by Suture Approximation.

Anterior cruciate ligament (ACL) rupture remains a debilitating orthopaedic pathology with a substantial economic and psychological burden on patients, especially athletes. The purpose of ACL reconstruction is to attain maximum joint stability and functionality, allowing patients to resume their previous level of activity. Several graft options and techniques are available for ACL reconstruction. The all-inside remnant-preservation technique is a minimally invasive approach aiming for improved proprioception, better graft integration, and increased graft strength via ACL augmentation by suture approximation with an optimal anatomic reconstruction. ACL augmentation is associated with a decreased risk of rerupture. Moreover, enhancement of knee proprioception via the presented technique allows an early return to activity by patients because weight bearing (with a brace) can be initiated as early as day 1 postoperatively. Patients can resume running activities by 2 months postoperatively and return to pivot sports by 3 months postoperatively. Despite this surgical procedure being technically demanding, it is associated with improved clinical outcomes and functional capacities. Patients are also found to better tolerate the postoperative rehabilitation protocol.

Arthroscopic Suture Bridge Anchor Repair of Comminuted Greater Tuberosity Fracture With Double-Row Biceps Tenodesis in Elderly Osteoporotic Patients.

Isolated greater tuberosity fractures with displacement require usually open reduction and fixation to prevent poor outcomes, but high levels of morbidity have been reported. Recently, newer techniques describe arthroscopic fixation of greater tuberosity fracture for young patients; however, in elderly patients with comminuted osteoporotic fractures, this entity is more complex. A new arthroscopic technique is described through a minimally invasive approach that allows the evaluation of the glenohumeral joint and the treatment of associated pathology. These comminuted fractures can be treated using suture bridge technique. Postoperatively, rehabilitation consists of a similar regimen to that of a rotator cuff repair. With the appropriate surgical technique, good clinical outcomes can be obtained.

A rare case of an anatomical variation of bilateral long head of the biceps brachii tendons identified within the substance of bifid subscapularis tendons.

The long head of the biceps tendon is stabilized in the intertubercular groove by several anatomical structures. Dislocation or identification of the biceps tendon into or within the subscapularis tendon is very rarely mentioned in the literature. This is the first reported case of bilateral identification of the long head of the biceps tendons within the lateral subscapularis tendon. This report presents the case of a 51-year-old male patient who presented for bilateral shoulder pain. After failure of conservative treatment, MRIs were done which identified bilateral biceps tendons within the subscapularis tendons, with a concomitant supraspinatus tear on the right side. He underwent right shoulder arthroscopic biceps tenotomy, with supraspinatus repair. The symptoms of the left shoulder diminished as a result of the continuation of conservative treatment. The long head of the biceps tendon normally travels through the intertubercular groove and is stabilized by soft tissue and bony structures. Medial dislocation of the tendon is affected by the medial wall angle and by the integrity of the soft tissue stabilizers; most importantly the coracohumeral ligament in the proximal part of the groove. Dislocation of the biceps tendon into the substance of the subscapularis has been rarely mentioned in the literature; and as far as we know, bilateral occurrence without any identifiable subscapularis tears has never been previously mentioned. The bilateral occurrence with the absence of subscapularis lesions indicates that this is a congenital anomaly.

Arthroscopic management of anterior labrum periosteal sleeve avulsion (ALPSA) lesions: A case series with improved clinical outcomes using a modified technique.

INTRODUCTION: Anterior labrum periosteal sleeve avulsion (ALPSA) is the avulsion of the labrum and of the non-disrupted periosteum with the subsequent healing of the labrum in a medialized nonfunctional position on the glenoid neck. OBEJCTIVE: In this study, a modified technique for arthroscopic repair of ALPSA lesions is presented, along with post operative clinical results and follow up. METHOD: 72 patients who underwent this procedure were included in this study. Patients with multidirectional instability, more than 20% of glenoid bone loss, and bony Bankart lesions were excluded. RESULTS AND CONCLUSION: It was concluded that with this modified technique, a lower recurrence rate post arthroscopic repair of ALPSA lesions was seen with only 4 patients having postoperative recurrence of glenohumeral dislocation which amounts to 5.6%. Moreover, the data also showed a statistically significant improvement of 35.23% between the pre- and postoperative ASES scores.

Anterior inferior iliac spine avulsion fracture post hip arthroscopy for Femoroacetabular impingement.

FAI (Femoroacetabular Impingement) is an uncommon yet reported pathology of the hip joint, especially in the young athletic population. If left untreated, it predisposes for premature osteoarthritis of the hip. FAI treatment modalities consists of either open or arthroscopic surgery, the latter becoming the most adapted modality. We present a case of a young male athlete found to have FAI, treated arthroscopically. His post operative follow up was complicated by anterior inferior iliac spine avulsion fracture due to post op protocol non compliance which was treated with ORIF, with satisfactory non symptomatic outcome.

Arthroscopic Repair for Posterior Shoulder Instability: Case series and surgical outcome.

PURPOSE: This study evaluates outcomes of a consistent arthroscopic stabilization technique for recurrent posterior instability. METHODS: 79 shoulders with symptomatic posterior instability treated with arthroscopic repair and evaluated at a follow-up of 36 months. The mean age was 25.4 years of which 66 males and 13 females, and in 75% the dominant shoulder was affected. A known traumatic injury had occurred in 80%, with 25% having a documented dislocation. Arthroscopic repair was performed through an anterosuperior 12 O'clock viewing portal. Suture anchor repairs were performed in 60 cases and plication to the intact labrum in 19. A shoulder immobilizer was used for 4 weeks, followed by progressive range of motion, weightlifting at 3 months and return to contact sports at 6 months. The 79 cases had complete pre-op and post-op shoulder outcome scores. RESULTS: Significant improvement from preoperatively to final follow-up was seen for ASES scores, from 58 to 93. All patients returned to their previous level of athletic activity. Two patients reported postoperative instability; none required reoperation. There were no other postoperative complications. CONCLUSIONS: This study represents a consecutive series of patients with recurrent posterior instability undergoing arthroscopic posterior stabilization. In this population arthroscopic posterior labral repair and capsular plication provided significant clinical improvement with low recurrence and revision rate.

Sacral Anatomical Orientation in the Lebanese Population.

INTRODUCTION: PI is currently used as the gold standard measurement in spinopelvic anatomy. There is a need for a reliable method to calculate sacral anatomic orientation (SAO) independent of posture and to establish its association with PI, which was previously established in a single study (Peleg et al., 2007). Therefore, the aim of our study is the application and verification of this association on a Lebanese sample. METHODS: Methods for measuring SAO and PI on living individuals are described. The study was carried out on 200 adult individuals using CT 3D images (volume-rendering method). Reliability (intratester and intertester) was evaluated using the intraclass correlation test. A regression analysis was carried out to evaluate the association between the two measurements. RESULTS: There were 103 females (51%) and 97 males (49%) with a mean age of 58.68 ± 19.6 years (min = 20; max = 93). The mean SAO and PI in our population were found to be 52.65° (SD = 8.16°) and 59.08° (SD = 12.53°), respectively. SAO and PI measurements were highly correlated (Pearson correlation test; r = -0.296, P < 0.0001 for our general population). PI can be predicted via SAO, i.e., SAO = (-0.193 × PI) + 64.057. CONCLUSIONS: SAO may be an important tool, alongside PI, in defining the sagittal shape of the spine and useful for understanding its association with spinal diseases as they are not affected by postural changes.

Efficacy and safety of systemic tranexamic acid administration in total knee arthroplasty: A case series.

INTRODUCTION: Total knee arthroplasty (TKA) are associated with significant postoperative blood loss. Tranexamic acid (TXA) is a potent agent with antifibrinolytic activity, that can be administered via the intravenous (IV) and/or topical (intra-articular, IA) route, which can possibly interrupt the cascade of events due to hemostatic irregularities close to the source of bleeding. However, the literature contains scarce scientific evidence related to IV only TXA usage in TKA. The current study aims to compare the outcome between patients who were administered IV TXA and a control group in terms of blood loss, transfusion rate, and incidence of deep vein thrombosis (DVT) and thromboembolism (TE). METHODS: 110 patients, who underwent TKA were placed into two groups: 1) 34 patients who received IV TXA; and 2) 76 patients in the control group. In the TXA group, patients received an IV TXA dose of 1 g, 30 min before incision. Two drains were placed. RESULTS: Usage of IV TXA showed better results when compared to the control group in terms of mean blood transfusion (0.5 less transfusion during hospital stay), hemoglobin drop (10%). No cases of DVT or TE were noted among the two study groups. CONCLUSION: Use of IV TXA provided significantly better results compared to no TXA use with respect to all variables related to postoperative blood loss in TKA. Moreover, TXA use is safe in terms of incidence of symptomatic DVT and TE.

Posterior shoulder instability due to isolated reverse HAGL lesion in a young gymnast: A rare mechanism of injury and surgical technique.

Humeral avulsion of the inferior glenohumeral ligament (HAGL) is a relatively important cause of shoulder instability, becoming a field of interest in the literature. Reverse HAGL lesions, a rare pathology compared to anterior disruptions; have been documented in only few cases as a notable cause of posterior instability. We describe in detail the mechanism of injury, diagnosis, arthroscopic repair and results.
