JSES International Dec 2020Deltoid compartment syndrome is a rare entity. The purpose of this study was to report a recent case and perform a systematic literature review.
BACKGROUND
Deltoid compartment syndrome is a rare entity. The purpose of this study was to report a recent case and perform a systematic literature review.
METHODS
Patient data were gathered from chart review and clinical encounters. For the review, the MEDLINE, Embase, and Ovid databases were queried for deltoid compartment syndrome cases. Seventeen articles reporting on 18 patients with deltoid compartment syndrome were included.
RESULTS
Including our patient, 9 of 19 patients (47.4%) presented with compartment syndrome limited to the deltoid. Most patients presented with additional affected compartments, most commonly in the ipsilateral arm (7 of 19, 37%). Isolated deltoid involvement often resulted from iatrogenic injury; of 10 iatrogenic reports, 8 involved only the deltoid. Of 19 cases, 5 (26%) occurred in powerlifters, climbers, or anabolic steroid or testosterone injectors. In 13 of 19 cases (68%), the patients were men aged 18-36 years, and only 1 female case (5%) was reported. Prolonged recumbence owing to substance abuse was documented in 6 of 19 cases (32%).
CONCLUSION
Deltoid compartment syndrome is rare, with only 19 reported cases, including our patient. Men are more commonly affected, and isolated deltoid compartment syndrome occurs in about 50% of reported cases. More than half of cases are iatrogenic, secondary to prolonged lateral decubitus positioning, injections, and surgical interventions about the shoulder. Prolonged recumbence from intoxication is also a common etiology. Providers should be aware of and recognize deltoid compartment syndrome to facilitate urgent surgical management.

Review
Ankle fractures are the fourth most common fracture requiring surgical management. The deltoid ligament is a primary ankle stabilizer against valgus forces. It is frequently ruptured in ankle fractures; however, there is currently no consensus regarding repair. A systematic database search was conducted with Medline, PubMed, and Embase for relevant studies discussing patients with ankle fractures involving deltoid ligament rupture and repair. Screening, quality assessment, and data extraction were performed independently and in duplicate. Data extracted included pain, range of motion (ROM), function, medial clear space (MCS), syndesmotic malreduction, and complications. After screening, 9 eligible studies from 1990 to 2018 were included (N = 508). Compared to nonrepair groups, deltoid ligament repair patients had lower syndesmotic malreduction rates (0%-9% vs 20%-35%, p ≤ .05), fewer implant removals (5.8% vs 41% p ≤ .05), and longer operating time by 16-20 minutes (p ≤ .05). There was no significant difference for pain, function, ROM, MCS, and complication rate (p ≤ .05). In conclusion, deltoid ligament repair offers lower syndesmotic malreduction rates and reduced re-operation rates for hardware removal in comparison to trans-syndesmotic screws. Repair groups demonstrated equivalent or better outcomes for pain, function, ROM, MCS, and complication rates. Other newer syndesmotic fixation methods such as suture-button fixation require further evaluation when compared to the outcomes of deltoid ligament repair. A randomized control trial is required to further examine the outcomes of ankle fracture patients who undergo deltoid ligament repair versus trans-syndesmotic screw fixation.

BACKGROUND
Brachial plexus and axillary nerve injuries often result in paralysis of the deltoid muscle. This can be functionally debilitating for patients and have a negative impact on their activities of daily living. In these settings, transferring the branch of the radial nerve innervating the triceps to the axillary nerve is a viable treatment option. Additional nerve transfers may be warranted. This study sought to determine the efficacy of nerve transfer procedures in the setting of brachial plexus and axillary nerve injuries and factors affecting clinical outcomes.
METHODS
The U.S. National Library of Medicine's website "PubMed" was queried for "radial to axillary nerve transfer" and "brachial plexus nerve transfer." An initial review by two authors was performed to identify relevant articles followed by a third author validation utilizing inclusion and exclusion criteria. Individual patient outcomes were recorded and pooled for final analysis.
RESULTS
Of the 80 patients, 66 (82.5%) had clinical improvement after surgical nerve transfer procedures. Significant difference in clinical improvement following nerve transfer procedures was correlated with patient age, mechanism of injury, brachial plexus vs isolated axillary nerve injuries, multiple nerve transfers vs single nerve transfers, and surgery within the first 7 months of injury. The branch of the radial nerve supplying the triceps long head showed improved clinical results compared with the branch of the radial nerve supplying the triceps medial head and anconeus.
CONCLUSION
Nerve transfers have been shown to be effective in restoring shoulder abduction in both isolated axillary nerve injuries and brachial plexus injuries.

INTRODUCTION
Treatment of post-surgical pain is predicated by an understanding of pain generators. The purpose of this review is to identify sensory dependent areas of the shoulder and discuss their correlation in treating postoperative pain.
MATERIALS AND METHODS
Pubmed, Embase, and Cochrane Database of Systemic Reviews were searched (key terms: "Nociception" or "sensory pain receptors" or "pain map" or "neuroanatomy and shoulder" or "rotator cuff") to identify studies in the current literature (1966-2018) regarding sensory innervation of the shoulder and rotator cuff. The search was limited to the English language, human studies, and publication types to reviews and clinical studies. Articles written in other languages besides English, animal studies, abstracts, and conference notes were excluded. Each search result was investigated for relevant physiological information of the nerve endings and nociceptors as well as pertinent information and figures that illustrated the location of the identified receptors.
RESULTS
A total of 12 articles were identified that addressed the sensory innervation of the shoulder. The shoulder capsule has the highest sensory nerve density. The attachment sites between the labrum and the capsule and glenoid rim were also found to be highly sensory dependent, in contrast to the peri-core zone at the capsulolabral junction, which was found to be less concentrated with fascicles and sensory nerve endings. The subacromial bursa is also a highly sensory dependent structure, with a more concentrated neural network on the coracoacromial side compared to other quadrants of the bursa. Cutaneous locations of sensory fibers on the shoulder are best defined by mapping the pressure pain threshold (PPT) of various locations on the shoulder. The most sensory dependent locations of the shoulder were found to be the posterior border of the acromion, the glenohumeral joint, the anterior deltoid, and the upper trapezius.
CONCLUSION
This review examined the origin of pain in the shoulder, the location of cutaneous pain receptors, and receptors in each major part of the shoulder. Providing analgesia to these densely innervated areas of the shoulder can potentially reduce pain associated with surgical trauma. In addition, knowledge of the sensory dependent areas of the shoulder may elicit consideration of alternative incision sites and surgical protocols to decrease the insult to nociceptors in these locations. These changes could possibly decrease the narcotic requirement in the postoperative period.

Review
Role of the kinetic chain in shoulder rehabilitation: does incorporating the trunk and lower limb into shoulder exercise regimes influence shoulder muscle recruitment patterns? Systematic review of electromyography studies.
OBJECTIVE
To investigate the influence of trunk and lower limb motion on electromyography (EMG) muscle activity and recruitment patterns around the shoulder.
DESIGN
Systematic review.
DATA SOURCES
MEDLINE, CINAHL, PEDro, AMED, PubMed, Cochrane Central Register of Controlled trials, Cochrane Database of Systematic reviews, SportsDiscuss and PROSPERO.
ELIGIBILITY CRITERIA
Studies investigating both multiregional kinetic chain (KC) shoulder exercises localised non-kinetic chain (nKC) shoulder exercises in healthy subjects under the same experimental conditions were included in this review.
RESULTS
KC exercises produced greater EMG activation levels in 5 of 11 studies for the lower trapezius. Of the remaining studies, five found no difference between the exercise types and one favoured nKC exercises. KC exercises produced greater EMG activation levels in 5 of 11 studies for the serratus anterior. Of the remaining studies, three reported the opposite and three found no significant difference between the exercise types. nKC exercises produced greater EMG activation in infraspinatus in three of four studies. KC exercises produced the lowest trapezius muscle ratios in all studies. Studies investigating the upper trapezius, middle trapezius, supraspinatus, subscapularis, biceps brachii, latifissimus dorsi, pectoralis major, deltoid, and trapezius and serratus anterior ratios showed inconsistency.
CONCLUSION
This review found evidence that integrating the KC during shoulder rehabilitation may increase axioscapular muscle recruitment, produce lower trapezius muscle ratios and reduce the demands on the rotator cuff. Stepping appears preferable to squatting.

This Review updates the scientific evidence assessing possible causal associations of adverse events following immunisation (AEFI) compiled in the 2012 report from the Institute of Medicine and the 2014 report from the Agency for Healthcare Research and Quality. For 12 of 46 AEFI examined, a causal relationship has been established with at least one vaccine currently routinely recommended to the general USA population: anaphylaxis, arthralgia or arthritis (mild, acute, and transient, not chronic), deltoid bursitis (when vaccine is administered improperly), disseminated varicella infection (in immune deficient individuals for whom the varicella vaccine is contraindicated), encephalitis, febrile seizures, Guillain-Barré syndrome, hepatitis (in immune deficient individuals for whom the varicella vaccine is contraindicated), herpes zoster, immune thrombocytopenic purpura, meningitis, and syncope. Other than mild acute and transient arthralgia or arthritis, which is very common in adult women after rubella vaccine, these adverse reactions are rare or very rare. Vaccines have an excellent safety profile overall and provide protection against infectious diseases to individuals and the general population.

PURPOSE
The first descriptions on medial talar tubercle fractures are attributed to Cedell. He described avulsion fractures of the insertion of the posterior talotibial ligament. However the true etiology has not been established. Since little is known about these fractures, they are easily misdiagnosed as simple ankle sprains. Untreated, these fractures may lead to chronic ankle pain. To improve the understanding of the etiology and outcome of these fractures a systematic review was conducted of all cases of isolated fractures of the medial tubercle of the posterior talar process. In addition we present the first series of competitive athletes treated by means of the two-portal hindfoot approach for isolated medial talar tubercle fractures.
METHODS
A systematic search was performed to identify all cases of medial tubercle fractures. Data on trauma mechanism, clinical presentation, imaging and treatment were extracted. In addition we retrospectively report on the results of endoscopically treated patients in our institution over the last fifteen years. Of all patients Numeric Rating Scores (NRS) for Satisfaction, Pain and Function, Foot Ankle Outcome Scores (FAOS), return to sport and complications were reported.
RESULTS
Eightteen articles were included reporting on 33 patients with an isolated fracture or avulsion of the posteromedial talar process. Most of the fractures occurred during sport activities (58%), followed by motor vehicle accidents (21%) and fall from height (12%). Of the activities during sport, 73% resulted following an ankle sprain. Reasonable to good outcomes are described in cases treated with immobilization, open reduction internal fixation or open excision. Of the nine patients treated in our institution, five were male and the median age was 29. All were participating in sports at a competitive level, with four of them being a professional athlete. In most patients the diagnosis was made more than a year after initial trauma. Ankle sprain was most common trauma mechanism. In some patients it was evident the avulsion was part or the deep portion of the deltoid ligament, however in two cases it was more likely an avulsion of the flexor hallucis longus (FHL) retinaculum. The median follow-up was 69 months (IQR 12.0-94.3). At final follow-up patients had little pain, NRS 1. Median NRS for satisfaction and function were 7 and 8, respectively. All patients did resume sport activities, however only four reached the preinjury level. Of the five patients that did not return to their pre-injury level of activity, two were professional athletes at the end of their career, and retired not due to ankle complaints. One complication was reported.
CONCLUSION
Fractures of the medial tubercle are rare and based on the available literature there is not one distinct trauma mechanism. Based on literature no recommendation for treatment can be made. Our results show endoscopic excision of the fragment as a save alternative for open surgical treatment.

BACKGROUND
Isolated distal fibular fractures resulting from supination external rotation (SER) injuries without evidence of obvious talar shift on standard radiographs present a diagnostic dilemma for clinicians. The status of the deep deltoid ligament, the main stabilizer of the ankle joint, is assessed by an increase in medial clear space (MCS) on radiographs. Therefore, these injuries can be either stable or unstable. In recent years, considerable clinical and research efforts have been made to determine ankle stability following SER fracture. The purpose of this systematic review was to evaluate and compare the role of different stress radiograph modalities in assessing stability of the ankle with SER fractures with no obvious talar subluxation on standard radiographs.
METHODS
The electronic databases MEDLINE, EMBASE, Ovid, Cochrane Central, CINAHL, and Google Scholar were searched from January 2000 to January 2018 to identify literature relating to radiologic assessment of stability of SER ankle fractures.
RESULTS
Our literature search revealed 10 peer-reviewed articles that fulfilled inclusion criteria. This yielded a total of 698 patients. The systematic review found 3 broad categories of radiographic investigations in the assessment of ankle joint stability: external rotation (ER) stress radiographs, gravity stress views (GSV), and weightbearing (WB) radiographs. Proponents of WB radiographs have demonstrated how axial load can normalize ankle joint alignment in cases of proven instability. There was a consistently high grade of evidence for using a medial clear space (MCS) value of more than 4 to 5 mm to indicate an unstable ankle following SER fracture.
CONCLUSION
In conclusion, the results of this systematic review support an MCS value of less than 4 to 5 mm as a good indicator of stability, regardless of choice of stress imaging modality. These patients can be allowed early weightbearing with expected good functional outcomes. Recent published literature favors WB stress radiographs as a reliable and safe technique for assessing stability in SER ankle fractures. However, it should be kept in mind that this is based on studies with relatively low grades of evidence.

PURPOSE
This systematic review assesses evidence for improvements in outcome for all reported types of treatment modalities [physical therapy, tenotomy or tenodesis of the long head of the biceps, debridement, partial repair, subacromial spacer, deltoid flap, muscle transfer, rotator cuff advancement, graft interposition, superior capsular reconstruction (SCR), and reversed shoulder arthroplasty (RSA)] used for irreparable posterosuperior rotator cuff tears without glenohumeral osteoarthritis. The primary aim was to be able to inform patients about expectations of the amount of clinical improvement after these treatments.
METHODS
A systematic search was conducted in MEDLINE, EMBASE, CINAHL, and Cochrane databases for studies on irreparable posterosuperior rotator cuff lesions without glenohumeral osteoarthritis, published from January 2007 until January 2019, with minimum 2-year follow-up. Studies with pre-operative and/or intra-operative determination of cuff tear irreparability were included. We defined the non-adjusted Constant Score as the primary outcome.
RESULTS
Sixty studies (2000 patients) were included with a fair mean quality score, according to the Modified Coleman Methodology Score. The employed definitions of 'irreparable' were mainly based on MRI criteria and were highly variable among studies. The smallest weighted mean preoperative to post-operative improvements in Constant Score were reported for biceps tenotomy/tenodesis (10.7 points) and physical therapy (13.0). These were followed by debridement (21.8) and muscle transfer (27.8), whereas the largest increases were reported for partial repair (32.0), subacromial spacer (32.5), rotator cuff advancement (33.2), RSA (34.4), graft reconstruction (35.0), deltoid flap (39.8), and SCR (47.4). Treatment using deltoid flap showed highest mean weighted improvement in Constant Score among studies with available medium-term (4-5-year) follow-up. Treatments deltoid flap, muscle transfer, and debridement were the only treatments with available long-term (8-10-year) follow-up and showed similar improvements in Constant Score at this time point.
CONCLUSION
The variability in patient characteristics, co-interventions, outcome reporting, and length of follow-up in studies on irreparable rotator cuff tears without osteoarthritis complicates sound comparison of treatments. Clinically important treatment effects were seen for all 11 different treatment modalities.

OBJECTIVES
The pectoralis major flap has been considered the workhorse flap for chest and sternoclavicular defect reconstruction. There have been many configurations of the pectoralis major flap reported in the literature for use in reconstruction sternoclavicular defects either involving bone, soft tissue elements, or both. This study reviews the different configurations of the pectoralis major flap for sternoclavicular defect reconstruction and provides the first ever classification for these techniques. We also provide an algorithm for the selection of these flap variants for sternoclavicular defect reconstruction.
METHODS
EMBASE, Cochrane library, Ovid medicine and PubMed databases were searched from its inception to August of 2019. We included all studies describing surgical management of sternoclavicular defects. The studies were reviewed, and the different configurations of the pectoralis major flap used for sternoclavicular defect reconstruction were cataloged. We then proposed a new classification system for these procedures.
RESULTS
The study included 6 articles published in the English language that provided a descriptive procedure for the use of pectoralis major flap in the reconstruction of sternoclavicular defects. The procedures were classified into three broad categories. In Type 1, the whole pectoris muscle is used. In Type 2, the pectoralis muscle is split and either advanced medially (type 2a) or rotated (type 2b) to fill the defect. In type 3, the clavicular portion of the pectoralis is islandized on a pedicle, either the thoracoacromial artery (type 3a) or the deltoid branch of the thoracoacromial artery (type 3b).
CONCLUSION
There are multiple configurations of the pectoralis flap reported in the English language literature for the reconstruction of sternoclavicular defects. Our classification system, the Opoku Classification will help surgeons select the appropriate configuration of the pectoralis major flap for sternoclavicular joint defect reconstruction based on size of defect, the status of the vascular anatomy, and acceptability of upper extremity disability. It will also help facilitate communication when describing the different configurations of the pectoralis major flap for reconstruction of sternoclavicular joint defects.
