Cubital Tunnel Syndrome Due to Multiple Intraneural Cysts at Elbow: A Case Report and Review of Literature.

Cubital tunnel syndrome is a common disorder that affects the upper limb and involves compression of the ulnar nerve. However, this syndrome is rarely caused by multiple intraneural ganglion cysts. Of all intraneural ganglion cysts, only 9% affect the elbow. This study presents a case report of a 73-year-old female patient who manifested pain, numbness, tingling, and paralysis of the medial aspect of her left forearm, fourth, and fifth fingers of the left hand for six months. Intraoperative findings showed multiple intraneural cysts at the left elbow, which were confirmed via histopathology. The cysts were surgically excised, whereas the ulnar nerve was released into the cubital tunnel and anteriorly transposed. Complete sensory and motor recovery were achieved. Although similar cases of intraneural cysts were reported in the literature, this case has the uniqueness of the unusual number and site of intraneural cysts in the ulnar nerve on the background of osteoarthritic changes. Therefore, the aim of reporting this case is to increase awareness of the presence of these cysts when the symptoms are severe.

Clinical results and radiological bony adaptations on a cementless short-stem prosthesis - A comparative study between anatomical and reverse total shoulder arthroplasty.

INTRODUCTION: Although the use of short stem and stemless shoulder prosthesis is trending, the surgical outcome may vary due to varying biomechanics. Objectives were to evaluate and compare the short-term clinical results and radiological changes between anatomical total shoulder arthroplasty (TSA) and reverse TSA (rTSA) with a short-stem humeral design. HYPOTHESIS: There is no clinical and radiological difference between TSA and rTSA using a short-stem humeral design. METHODS: This retrospective study included 66 patients who underwent TSA and rTSA (33 patients each) with a minimum 2-year follow-up. Radiographic findings, including preoperative Tingart cortical index (TCI), postoperative filling ratios of metaphysis (FRmet) and diaphysis (FRdia), bone adaptations, and osteolysis around the humeral stem at the immediate postoperative period, and the most recent follow-up were measured. Pre and postoperative Constant-Murley score, subjective shoulder value (SSV), and complications were noted. RESULTS: At a mean follow-up of 27 (range 24-50) months, FRmet was significantly higher in rTSA group than the TSA group (0.65 vs. 0.60, p=0.009). Bone resorption was similar in both groups (p=0.76) and was correlated to a lower TCI value of<2.9mm (p=0.02). Despite significant clinical improvement in individual groups, the comparison between groups was non-significant (p>0.05). Negative correlation was observed between TCI and total clinical score (p=0.045) in TSA group, active external rotation (p=0.019), activity (p=0.005), SSV (p=0.008) and total score (p=0.025) in rTSA group. Radiographic changes were not influenced by patient characteristics and clinical results (p>0.05). CONCLUSION: Although no radiographic difference was observed between TSA and rTSA, better short-term clinical results observed with the usage of the short-stem humeral design prosthesis are encouraging.

"Tomydesis" might be a reliable technique for lesions of the long head of the biceps tendon associated with rotator cuff tears: a minimum 6-month prospective clinical follow-up study.

PURPOSE: To compare the clinical outcomes of self-locking T-tenotomy called "tomydesis" to three different techniques of tenodesis for lesions of the long head of the biceps tendon (LHBT) associated with rotator cuff tears. HYPOTHESIS: Tomydesis could provide similar clinical outcomes than the other LHBT tenodesis techniques. METHODS: This prospective multicentre study included 77 patients who underwent rotator cuff repair concomitant with one of four surgical techniques on the LHBT. All patients had a minimum of 6-month follow-up post-operatively. Outcomes were evaluated based on the Constant score, SSV, pain on visual analogue scale, biceps-specific pain and Popeye deformity on photographs. RESULTS: There was no difference for the pain at the biceps muscle belly (p = 0.58), the bicipital groove (p = 0.69) and during resisted supination (p = 0.53), as well as for muscle cramps (p = 0.09), VAS for pain (p = 0.12) and Popeye deformity (p = 0.18). There was more pain in resisted flexion in the tomydesis group (p = 0.032), and significantly better Constant scores and SSV (< 0.001) in the patients who underwent the double lasso loop technique, but non-repairable cuff tears were most frequent in the tomydesis group. CONCLUSIONS: Tomydesis might be a reliable alternative that combines advantages of tenodesis and tenotomy. It should be considered in cases of rotator cuff tears, whose repair and healing are the key for good functional outcomes. LEVEL OF EVIDENCE: II.
