المؤلفون: Eun Ah Hong, Mee-Gang Kim, Yong Seok Nam, Jong In Lee

المصدر: Muscle & Nerve. 63:405-412

الوصف: Background We investigated the branching pattern and topographic anatomy of the nerves to the teres minor (Tm) and the long head of the triceps brachii (LHT) in relation to reference lines extending between surface landmarks, to identify the innervation patterns of, and the optimal needle placement points within, the Tm and the LHT. Methods The anatomical courses of the nerves to the Tm and the LHT were investigated in 37 upper limbs of fresh-frozen cadavers. Distances from the acromion to nerve penetration points, and crossing points of reference lines with the Tm and LHT were measured in 27 cadaveric upper limbs. Results The Tm was innervated by the axillary nerve in all specimens in three patterns, and the LHT was innervated exclusively by the radial nerve. Our dissection and measurements indicate that the midpoint of the reference line from the acromion to the inferior angle of the scapula is the optimal needle insertion point for the Tm. The target point for the LHT appears to be the one-third point of the reference line from the acromion to the medial epicondyle, or the two-thirds point of the reference line from the acromion to the axillary fold. Conclusions We investigated the branching pattern of the nerves to the Tm and the LHT and propose optimal needle placement points for electromyography of the Tm and LHT.

المصدر: Journal of Shoulder and Elbow Surgery. 29:e394-e399

الوصف: Introduction Scapular dyskinesis caused by traumatic detachment of the serratus anterior muscle from its insertion site on the inferior angle of the scapula is a very rare condition. Only a few case reports describe such an injury which is reported to be treated conservatively in almost all studies. Methods We report our unique experience with a 58-year-old policeman who was referred to our clinic four months after a direct trauma on his scapula. He presented with shoulder pain and clinically obvious medial winging for which no specific treatment had been undertaken until then. Delayed initial management with well conducted physical therapy for an additional 3 months showed no improvement on the patient's complaint. Electroneuromyography was normal. Radiographs and computed tomography revealed a bony flake at the inferior angle of the scapula, raising our suspicion of serratus anterior muscle avulsion which was confirmed by MRI. We attempted a surgical exploration and transosseous reinsertion of the avulsed serratus anterior muscle. Results Postoperative controls were done at 6 weeks, 3 months and 1 year. 3 months after surgery, the patient reported complete relief of his shoulder pain and we observed back to normal shoulder range of motion without scapular dyskinesis. Follow-up radiographs showed good positioning and consolidation of the avulsed bony fragment. At 1 year, the patient reported complete return to normal activity and quality of life with no relapse nor surgical complication. Constant Shoulder Score and Subjective Shoulder Value raised from 52 and 50% before surgery to 80 and 90% respectively at one-year postoperative. Conclusion Surgical repair of traumatic avulsions of the serratus anterior muscle might be a safe and efficient therapeutic option.

الوصف: We report a series of 10 patients with unilateral, dynamic, winged scapula (WS), without cause, that was diagnosed as voluntary winging of the scapula (VWS). We compared clinical, electrodiagnostic, and other examination data for 10 patients with VWS and 146 with dynamic WS-related neuromuscular disorders, to establish a detailed pattern of the VWS subtype. In VWS, electrodiagnostic and other examinations did not reveal any neuromuscular or orthopedic cause. Winging was dynamic, obvious, neither medial nor lateral, and mainly involved the inferior angle of the scapula, in young patients. VWS never appeared during floor push-ups. Patients could produce WS at will with the index and healthy shoulder, between 25° and 65° of anterior elevation, or with shoulder internal rotation. VWS is a benign disorder that can be distinguished from neuromuscular WS by normal electrodiagnostic results for muscles and nerves of both shoulders and two specific clinical tests.

A computer tablet software can quantify the deviation of scapula medial border from the thoracic wall during clinical assessment of scapula dyskinesis

المؤلفون: Konstantinos Tsikopoulos, Dimitrios Kitridis, Trifon Totlis, Anastasios D. Georgoulis

المصدر: Knee Surgery, Sports Traumatology, Arthroscopy. 29:202-209

الوصف: Aim of this study is to establish an objective and easily applicable method that will allow clinicians to quantitatively assess scapular dyskinesis during clinical examination using a computer tablet software. Hypothesis is that dyskinetic scapulae present greater motion—deviation from the thoracic wall—compared to the non-dyskinetic ones and that the software will be able to record those differences. Twenty-five patients and 19 healthy individuals were clinically evaluated for the presence of dyskinesis or not. According to the clinical diagnosis, the observations were divided into three groups; A. Dyskinetic scapulae with symptoms (n = 25), B. Contralateral non-dyskinetic scapulae without symptoms (n = 25), C. Healthy control scapulae (n = 38). Then, all individuals were tested using a tablet with the PIVOT™ image-based analysis software (PIVOT, Impellia, Pittsburgh, PA, USA). The motion produced by the scapula medial border and inferior angle deviation from the thoracic wall was recorded. The deviation of the medial border and inferior angle of the scapula from the thoracic wall was 24.6 ± 7.3 mm in Group A, 14.7 ± 4.9 mm in Group B, and 12.4 ± 5.2 mm in Group C. The motion recorded in the dyskinetic scapulae group was significantly greater than both the contralateral non-dyskinetic scapulae group (p

Port Placement in Robotic Thoracic Surgery for Inferior Mediastinal Tumors

المؤلفون: Mariko Fukui, Takeshi Matsunaga, Aritoshi Hattori, Hiroyasu Ueno, Kazuya Takamochi, Kenji Suzuki, Yukio Watanabe

المصدر: The Annals of thoracic surgery. 113(2)

الوصف: Robotic surgery for inferior mediastinal tumors located below the inferior vein is rare. The difficulty of resection varies depending on port placement and approach, especially on the left side. Considering that we have tried three different approaches for left inferior mediastinal tumors, we identify the advantages and disadvantages of each method. The approach from three arms and one assist placed on the ventral side of the inferior angle of the scapula is the best access for inferior mediastinal tumors. If the Si system is used, the patient cart should approach from the caudal side and dock on the dorsal side.

الوصف: Background The dorsolateral branch of the posterior intercostal artery (DLBPI) can be easily found while harvesting a latissimus dorsi (LD) musculocutaneous flap for breast reconstruction. However, it remains unknown whether this branch can be used for a free flap and whether this branch alone can provide perfusion to the skin. We examined whether the DLBPI could be reliably found and whether it could provide sufficient perfusion. Methods We dissected 10 fresh cadavers and counted DLBPIs with a diameter larger than 2 mm. For each DLBPI, the following parameters were measured: distance from the lateral margin of the LD muscle, level of the intercostal space, distance from the spinal process, and distance from the inferior angle of the scapula. Results The DLBPI was easily found in all cadavers and was reliably located in the specified area. The average number of DLBPIs was 1.65. They were located between the seventh and eleventh intercostal spaces. The average length of the DLBPI between the intercostal space and the LD muscle was 4.82 cm. To assess the perfusion of the DLBPIs, a lead oxide mixture was injected through the branch and observed using X-rays, and it showed good perfusion. Conclusions The DLBPI can be used as a pedicle in free flaps for small defects. DLBPI flaps have some limitations, such as a short pedicle. However, an advantage of this branch is that it can be reliably located through simple dissection. For women, it has the advantage of concealing the donor scar underneath the bra band.

المؤلفون: Goo Young Kim, Dong Hwee Kim, Seong Gyu Lim, Ki Hoon Kim, Byung Kyu Park

المصدر: PM&R. 10:1380-1384

الوصف: Background Safe and accurate needle access to the rhomboid major (RM) during electromyography is challenging due to the overlying trapezius muscle and the risk of pneumothorax. Objective To investigate the RM anatomy associated with the trapezius using ultrasonography and to determine a safe and accurate needle insertion point for needle electromyography of the RM. Design Descriptive study. Setting Department of physical medicine and rehabilitation of a tertiary clinic center. Participants Participants between 23 and 71 years of age without any diseases (N = 25; 13 men, 12 women; 50 scapulae) were included. Interventions Ultrasonography of the RM and trapezius muscles around the scapula. Main Outcome Measures The point at which the lateral margin of the trapezius crosses the medial border of the scapula (point A) was determined. The probe was positioned at the level of the midpoint (point M) between point A and the inferior angle of the scapula. The horizontal distance from the point at which the RM was the thickest (point X) to point M was measured. At point X, the depth of the RM, RM thickness, and the depth of the pleura were measured. Results The mean age and body mass index were 37.4 ± 12.0 years and 22.3 ± 2.1 kg/m2, respectively. Point M was located at a mean distance of 3.9 ± 0.6 cm proximal to the inferior angle of the scapula. The mean distance between point X and point M was 1.0 ± 0.2 cm. At point X, the RM was at a mean depth of 9.7 ± 3.1 mm from the skin and had a mean thickness of 9.9 ± 1.8 mm. The pleura was observed at a mean depth of 28.4 ± 3.8 mm from the skin. Conclusion Needle electromyographic examination of the RM can be performed easily and safely through the lower part of the RM that is not covered by the trapezius. Level of Evidence not applicable.

المصدر: European journal of orthopaedic surgerytraumatology : orthopedie traumatologie. 31(4)

الوصف: Lower trapezius (LT) transfer using Achilles tendon allograft or semitendinosus autograft is effective in restoring external rotation in massive irreparable posterosuperior rotator cuff tears (RCT). The purpose of this study was to evaluate if the infraspinatus fascia (IF) could be used in LT transfer to extend the LT tendon. Eight fresh-frozen whole-body cadavers were dissected using both shoulders, beach chair position. A 2.5–3 cm wide bundle of the IF was dissected, from the inferior angle of the scapula up to the insertion of the LT which was then detached subperiosteally in continuity with the fascia. The extended tendon was reinforced with sutures and brought to the center of the footprint of the supraspinatus on the humerus. We measured: (a) the distance between the insertion of the LT on the scapula and the inferior angle of the scapula, estimating the length of the IF that can be harvested, (b) the distance between the insertion of the LT on the scapula and the center of footprint of the infrastinatus on the humerus, estimating the distance needed to be covered by the graft (c) the length of the extended tendon between the center of footprint of the infrastinatus on the humerus (fixation point) and its free end, estimating the length available for fixation. The mean length of the fascia that can be harvested is 125.56 mm. The mean distance that needs to be covered by the graft is 100 mm. The extended tendon is long enough leaving 24.69 mm for fixation. The transfer of the LT extended with the IF on the footprint of the infraspinatus is feasible. It could be a viable alternative to the currently used grafts in LT transfer in irreparable posterosuperior RCT.

Scapular body fracture and concomitant inferior angle apophyseal separation with intrathoracic displacement: a case report

المؤلفون: Yoo Joon Sur, Hyuk Jin Jang, Ho Youn Park

المصدر: Journal of Pediatric Orthopaedics B. 26:429-432

الوصف: A 10-year-old patient presented to the emergency room after a motor vehicle accident. The patient was diagnosed with left scapular body fracture and concomitant inferior angle apophyseal separation with intrathoracic displacement causing hemopneumothorax. The displaced scapular body was reduced surgically and separated apophysis of the inferior angle was fixed to the scapular body with absorbable suture. Postoperative 2-year follow-up showed a good result. A literature search found two pediatric cases of intrathoracic displacement of scapular body fracture. There was no previous report of apophyseal separation of the inferior angle of the scapula.
