“…Abbreviations: SSN -suprascapular notch's; MD -maximum depth; STD -superior transverse diameter. In the study done by Apurba Patra et al, in 67.34 % scapulae transverse diameter of the notches is more than vertical diameter and in 14.28 % vertical diameter was more than transverse diameter [14,15]. Which was also same in present study (Transverse diameter > Verticle diameter).…”

Relevance. The suprascapular notch is one of the most crucial areas of the scapula from a clinical standpoint. Aside from its anatomical relevance, the suprascapular notch type may also have some clinical implications for suprascapular nerve entrapment. Aim of the study was the determination of the different dimensions of the suprascapular notch based on the maximum depth (MD) and superior transverse diameter (STD), as well as the clinical relation between those dimensions and suprascapular nerve entrapment. Materials and Methods. The study’s materials were 100 unknown dry human scapulae from the from the anatomy department of the Mahatma Gandhi Medical College, Sitapura, Jaipur, Rajasthan. Each scapula was studied for suprascapular notch. From each of the scapulae, maximum depth and superior transverse diameter were determined. Fifty were from right side and Fifty were from left side. Different types of suprascapular notches were observed based on maximum depth and superior transverse diameter. Results and Discussion. In this study, the overall percentage distribution frequency of the suprascapular notch in 100 scapulae is MD STD (25 %), MD = STD (0 %), STD MD (60 %) and SSN Absent (15 %) respectively. The most common SSN type is STD MD (60 %) type and least common SSN type is MD = STD (0 %) type. Conclusion. Morphological examination of the scapular notch reveals a common site of nerve compression and also demonstrates the surgical importance of the scapular nerve during shoulder surgery.

“…These dimensional variations are population specific and may be attributed to genetic, environmental and regional differences [ 9 - 11 ]. Clinically, such variations have profound implications in the management of patients with symptoms associated with suprascapular neuropathy particularly suprascapular nerve entrapment associated with complete ossification of the suprascapular ligament [ 13 - 15 ].…”

“…The prevalence of type I in the present study, however, is consistent with the findings from a similar study by Kumar et al . 2014 in Singapore, who reported 87 scapulae (32.46%) [ 15 ]. On the contrary, type II suprascapular notch was the most common type in India observed in 61 scapulae (34.65%) and in China observed in 171 scapulae (58.16%).…”

Introduction the anatomy of the suprascapular notch and its relationship to scapular dimensions are critical in the management of suprascapular neuropathies. Individuals show considerable differences in the dimensions of the suprascapular notch across populations. The purpose of this study was to determine the morphology and morphometric dimensions of the suprascapular notch in adult Malawian cadavers and to suggest clinical implications associated with complete ossification of the suprascapular ligament. Methods adult dry scapulae from undetermined sex specimens (n=125) obtained from the skeletal collection at Kamuzu University of Health Sciences were classified according to the Rengachary categorization method to assess the suprascapular notch superior transverse distance, mid transverse distance, depth, scapula length and width using a standard Vernier caliper. Results the most prevalent suprascapular notch class was type I, which was found in 46 (36.8%) of all scapulae. Type VI was the least common, found in only 1 (0.8%) of the scapulae. The mean notch superior transverse distance was 1.3 ± 0.6 cm, while the mean maximum depth was 0.6 ± 0.3 cm. Only the differences in depth, however, were statistically significant (p=0.001). Conclusion the current study has described the morphology and morphometry of the suprascapular notch in relation to the risk of suprascapular nerve entrapment associated with complete ossification of the suprascapular ligament. Our sample population generally showed smaller suprascapular notch and scapular dimensions than other populations. This should be considered during the management of suprascapular neuropathy and preoperative planning of surgical operations of the shoulder region.

“…It can be trapped at the suprascapular and spinoglenoid notches where the nerve is fixed by ligaments in a bony canal [134]. The first symptom is pain localized in the posterior aspect of the shoulder that gets worse with activity, when lying on the affected area, or by shoulder adduction crossing the midline with the extended arm [33].…”

Nerves pass from one body area to another through channels made of connective tissue and/or bone. In these narrow passages, they can get trapped due to anatomic abnormalities, ganglion cysts, muscle or connective tissue hypertrophy, tumours, trauma or iatrogenic mishaps. Nearly all nerves can be affected. The clinical presentation is pain, paraesthesia, sensory and motor power loss. The specific clinical features will depend on the affected nerve and on the chronicity, severity, speed and mechanism of compression.Its incidence is higher under some occupations and is some systemic conditions: diabetes mellitus, hypothyroidism, acromegaly, alcoholism, oedema and inflammatory diseases. The diagnosis is suspected with the clinical presentation and provocative clinical test, being confirmed with electrodiagnostic and/or ultrasonographic studies. Magnetic Resonance Studies (MRI) rule out ganglion cysts or tumours. Conservative medical treatment is often sufficient. In refractory ones, surgical decompression should be performed before nerve damage and muscle atrophy are irreversible. The 'double crash' syndrome happens when a peripheral nerve is compressed at more than one point along its trajectory. In cases with marked muscle atrophy, a 'supercharge end-to-side' nerve transfer can be added to the decompression. After decompression in those few cases with refractory pain, a nerve neurostimulator can be applied.
