Surgical treatment of an aseptic fistulized acromioclavicular joint cyst: a case report and review of the literature.

An acromioclavicular joint cyst is an uncommonly reported condition, which seems to result from a massive rotator cuff tear and degenerative osteoarthritis of the acromioclavicular joint. We present the case of an 81-year-old man affected by an acromioclavicular joint cyst, associated to a massive rotator cuff tear, proximal migration of the humeral head and osteoarthritis of the gleno-humeral joint. The mass was 7 x 2.5 cm in size and the overlying skin presented a fistula that drained clear synovial-like fluid. Plain X-ray examination of the left shoulder showed proximal migration of the humeral head migration and osteoarthritis of the gleno-humeral joint, and further MRI evaluation confirmed the clinical diagnosis of a complete rotator cuff tear and observed a large subcutaneous cyst in communication with the degenerative acromioclavicular joint. The patient underwent surgical excision of the cyst and lateral resection of the clavicle to prevent disease recurrence. To the best of our knowledge, this is the first reported case of an acromioclavicular joint cyst complicated by an aseptic fistula resulting from multiple aspirations

A rare case of subcutaneous traumatic index finger both extensor tendons rupture. Results of WALANT extensor digiti minimi transfer and literature review

Traumatic subcutaneous index finger both extensor tendons ruptures are rare injuries. Aim of the present paper is to review the literature about this uncommon lesion and to describe the case of 56 years old woman injured when her hand became stuck under a weight during a wrist hyperflexion movement. Surgical treatment was undertaken after 7 days. An extensor digiti minimi (EDM) tendon transfer and a Pulvertaft tenodesis on the index EDC to middle EDC using wide awake local anesthesia no tourniquet (WALANT) technique was performed. The advantage is to allow immediate visualization of active motion and confirmation of appropriate soft tissue tensioning. In our patient no complications were observed and an early rehabilitation program was started. The patient recovered full function at 2 months and resumed hear heavy labour working activity at 4 months

Early weight bearing in tibial plateau fractures treated with ORIF: a systematic review of literature

Background: To review the current clinical evidence on advantages and risks of early weight bearing (EWB) after internal fixation for tibial plateau fracture. Methods: Data source: PubMed and Google Scholar from inception of database to 20 August 2021, using PRISMA guidelines. The included studies were randomized controlled trials, prospective and retrospective observational studies, case reports. Data extraction was performed independently by 2 reviewers. Collected data were compared to verify agreement. Statistical analysis was not performed in this study. Results: The literature search produced 174 papers from PubMed and 186 from Google Scholar, with a total amount of 360 papers. The two reviewers excluded 301 papers by title or duplicates. Of the 59 remaining, 33 were excluded after reading the abstract, and 17 by reading the full text. Thus, 9 papers were finally included in the review. Conclusions: EWB can be considered safe and effective in selected cases after internal fixation for tibial plateau fractures. Level of evidence Therapeutic Level III

Mechanobiology of indirect bone fracture healing under conditions of relative stability: a narrative review for the practicing clinician

Mechanical influence on secondary fracture healing remains an incompletely understood phenomenon. This is of special importance in biological osteosynthesis, where stability is sacrificed for the sake of an optimal biological fracture environment. Under condition of relative stability, a wide range of biomechanical conditions can be achieved. Mechanobiology, which studies mechanical influences on biological systems has become a large, interdisciplinary field. The aim of this article is to present a comprehensive synthesis of the literature for the practicing clinician, with insights relevant to their practice of fracture care

Long-term outcome of Rockwood capsular shift for recurrent shoulder dislocation

Purpose. To review the long-term outcome of Rockwood capsular shift for recurrent shoulder dislocation secondary to trauma. Methods. Records of 30 males and 4 females who underwent Rockwood capsular shift for recurrent (≥2 episodes) anterior shoulder dislocation were reviewed. An additional Bankart repair with different techniques was performed in 24 of the patients by 2 different surgeons. The outcome was assessed using the Western Ontario Shoulder Instability Index (WOSI) and the Western Ontario Osteoarthritis of the Shoulder (WOOS) index questionnaires, the modified Rowe score, and the Constant-Murley score. Shoulder range of motion (ROM) was measured. Degenerative joint changes were evaluated on radiographs. Results. During a mean follow-up of 13 (range, 10–16) years, 6 (18%) patients had a mean of 1.2 recurrent dislocations. Four of the patients reported a traumatic event during recurrent dislocation. Of the 6 patients, 3 had undergone a Bankart lesion repair. Better Rowe and adjusted Constant scores were associated with lower age at first dislocation, at the index surgical procedure, and at follow-up. Four patients developed glenohumeral osteoarthritis: 2 were mild or moderate and 2 were severe and symptomatic. Glenohumeral osteoarthritis was associated with follow-up duration (p=0.03) and poorer Rowe score (p=0.012), adjusted Constant score (p=0.001), and WOOS score (p=0.006). Conclusion. Rockwood capsular shift can preserve shoulder ROM, with rates of recurrent dislocation and degenerative joint changes comparable with other techniques

Atypical Bilateral Femur Fractures in a Long-Term Bisphosphonate Therapy: A Case Report

Atypical Femur Fractures (AFF) are associated with Bisphosphonate Osteoporosis Therapy. Bisphosphonate therapy is widely used as the Gold-Standard Therapy for Osteoporosis: it increases bone density and reduce the risk of vertebral, non-vertebral and hip fractures. However, long-term alendronic acid administration can causes severely suppressed bone turnover and finally non-traumatic stress fractures. Here we present a case of Non-Traumatic stress fractures of bilateral femoral shafts in a Long-Term Alendronic Acid Therapy

Should age be a factor in treatment choice of periprosthetic Vancouver B2-B3 proximal femur fractures? A retrospective analysis of mortality and functional outcomes in elderly patients

Background and aim of the work Revision Arthroplasty (RA) is considered the treatment of choice for periprosthetic femur fractures (PFF) presenting with a loose stem. In the elderly RA may be associated with high post-operative mortality and complications. The aim of this study is to compare mortality and functional outcomes of open reduction internal fixation (ORIF) and RA for B2-B3 PFF in the elderly. Methods The study population included 29 patients (>65 years) surgically treated for B2-B3 PFF at the Orthopedic and Traumatology Unit of Cattinara University Hospital in Trieste (Italy) between January 2015 and December 2019. 16 patients were treated with ORIF and 13 with RA. Mortality and functional outcomes were analyzed. Results In-hospital (6,25% vs 7,69%) and 3 months (6,25 vs 15,38%) mortality was higher in the RA group. Mortality rates were particularly high in the > 85-year-old patients within four months from RA treatment. One year (38,46% and 16,67%) and overall mortality (69,22% and 25%) was higher after ORIF. Average time to weight-bearing and ambulation was 2.6 and 5.25 months for ORIF patients and 1.3 and 2.4 months for RA. A correlation was found between delayed weight-bearing and overall mortality. Conclusions Age is a risk factor for short term mortality following RA. Patients >85 years of age could benefit from a less invasive procedure such as ORIF. Long term outcomes are generally better for patients who undergo RA but further studies are necessary to evaluate the risk-benefit ratio of RA treatment compared to ORIF in elderly patients

Muscle Asymmetries in the Lower Limbs of Male Soccer Players: Preliminary Findings on the Association between Countermovement Jump and Tensiomyography

Strength and power asymmetries have been observed in different sports, including soccer. Such asymmetries, as well as the bilateral deficit (BLD), can be assessed during different tasks, static or dynamic, and with different methods and devices, in order to detect the possible different aspects, as well as the association with physical performance and injuries. The aim of this study was to investigate the association between muscle asymmetries and BLD during a countermovement jump (CMJ), and tensiomyography (TMG) parameters and asymmetries, in the lower limbs of male soccer players. A total of 23 male soccer players (18 ± 4 years) were recruited. Bilateral and unilateral CMJs were performed, and peak power (W) and height (cm) were obtained. TMG was performed on different muscles of the lower limbs, and lateral and functional symmetries were obtained. Playing position and history of injuries were collected. CMJ inter-limb symmetry was found to significantly correlate with biceps femoris (r = 0.574, p = 0.004) and soleus (r = 0.437, p = 0.037) lateral symmetry. Players in central roles presented significantly worse functional symmetry scores of the knee than defense players (−17.5%, 95% CI −31.2–−3.9; p = 0.10). Participants reporting a history of injury at the ankle were characterized by significantly lower functional symmetry in both the dominant (43%, 39.5–48.0 vs. 74.5%, 46.5–89.3, p = 0.019) and non-dominant (45%, 42.5–46.0 vs. 81.0%, 45.8–90.3, p = 0.024) ankle. Findings from this preliminary study suggest an association between lower-limb muscle asymmetries during a dynamic task, such as jumping, and muscle contractile properties evaluated with TMG; moreover, functional asymmetries may be present after ankle injuries. Future studies in larger samples should evaluate the presence of such asymmetries as predictors or characteristics of different muscular and joint injuries

Early weight bearing in acetabular and pelvic fractures

The incidence of pelvic and acetabular fractures is increasing during the years, counting 37 pelvic fractures per 100000 people annually. No weight bearing or toe touch weight bearing are usually chosen in the initial management to allow fracture and ligamentous healing and avoid fracture displacement and fixation failure. On the other hand, early weight bearing may stimulate fracture healing and allow prompt functional recovery, faster return to work and recreational activities and reduce complications linked to late rehabilitation.  Aim of the study is to review the literature about weight bearing indications for pelvic and acetabular fractures to highlight clinical and biomechanical evidence supporting early weight bearing
