A Retrospective Case Series Study on a Minimally Invasive Ultrasound-Guided First Dorsal Compartment Release Technique for Refractory De Quervain Tenosynovitis.

OBJECTIVE: The aim of this study was to evaluate the outcomes of patients treated with a novel minimally invasive complete release of the first dorsal compartment percutaneously under ultrasound guidance using an 18-gauge needle with an 18 blade at the tip. DESIGN: This was a retrospective case series. Nine adults (ten wrists) were included in the study of this technique. All patients had failed conservative care and had tenderness to palpation over the first dorsal compartment, a positive Finklestein test, and confirmed tenosynovitis with ultrasound imaging before the procedure. The main outcome measures were reduction in pain as determined by the numeric rating scale and improvement of function determined by the Nirschl Phase scale at both short- and long-term follow-up. RESULTS: There was 100% follow-up, with mean (SD) follow-up occurring at 23.1 (9.8) mos (range, 9-42 mos). From preprocedure to follow-up, numeric rating scale pain decreased from 4.1 (SD, 2.5) to 0.0 (SD, 0.0) ( P < 0.001), and Nirschl phase improved from 2.5 (SD, 1.9) to 0.2 (SD, 0.4) ( P = 0.03). No patients required revision open-release surgery or suffered neurovascular complications. CONCLUSION: This technique resulted in significant improvement of pain and function for all patients and no short- or long-term neurovascular complications were seen.

Short-term outcomes after pure bone marrow aspirate injection for severe knee osteoarthritis: a case series.

Background: Bone marrow aspiration (BMA) is among a group of autologous cell-based therapies currently being explored to treat osteoarthritis (OA). Materials & methods: This retrospective case study observed ten patients (13 knees) with severe knee OA who failed extensive conservative treatment and were treated with BMA injection using a novel, pure bone marrow aspiration (pBMA) technique. Results: No adverse events were reported. More than 50% reduction in the visual analog scale score for pain was observed at 2- and 12-weeks post-procedure, showing statistical significance. At 64 ± 26 weeks post-procedure, average knee pain remained significantly less than pre-procedure. Conclusion: Therefore, patients with severe knee OA may achieve significant relief after a BMA injection obtained using this pure bone marrow aspiration technique.

Ultrasound-Guided Ganglionectomy of a Flexor Hallucis Longus Ganglion Cyst Using Coablation Technology: A Case Report.

A 44-year-old woman with a history of an open ganglionectomy 2 years prior presented with a recurrent ganglion cyst. The ganglion cyst, extending from the flexor hallucis longus tendon sheath, was confirmed with magnetic resonance imaging. The patient declined another surgical incision. An experimental procedure was performed: ultrasound-guided ganglionectomy using a coablation wand. She achieved full symptom resolution, with no recurrence 1 year afterwards. To our knowledge, this is the first case report in the literature describing the use of this instrument for treating a ganglion cyst.

THE USE OF SERIAL PLATELET RICH PLASMA INJECTIONS WITH EARLY REHABILITATION TO EXPEDITE GRADE III MEDIAL COLLATERAL LIGAMENT INJURY IN A PROFESSIONAL ATHLETE: A CASE REPORT.

BACKGROUND: Medial collateral ligament (MCL) injuries are one of the most commonly treated knee pathologies in sports medicine. The MCL serves as the primary restraint to valgus force. The large majority of these injuries do not require surgical intervention. CASE SUBJECT DESCRIPTION: A 30-year-old professional wrestling athlete presented to the clinic with acute complaints of right medial knee pain resulting from a traumatic valgus force. Physical exam revealed Grade 3 MCL injury. Magnetic resonance imaging confirmed clinical diagnosis of a Grade 3 proximal MCL tear. This athlete had sustained a prior grade 3 ACL injury with Grade 3 distal MCL injury which required surgery to reconstruct the ACL and repair the MCL 13 months prior, in November of 2015. OUTCOMES: The subject was successfully treated with a series of three sequential Leukocyte Rich Platelet Rich Plasma (LR-PRP) Injections spaced evenly one week apart in addition to an early physical therapy regimen. The total treatment time was cut down from an expected 35-49 days to 31 days. DISCUSSION: When paired with the appropriate rehabilitation treatment progression, the use of LR-PRP injections in the treatment of an isolated MCL tear was beneficial for this subject. CONCLUSION: The results of this case report indicate that the use of LR-PRP and early rehabilitation shows promise in treating an acute grade 3 MCL injury. Future research utilizing randomized controlled trials are needed. LEVEL OF EVIDENCE: Case Report, 4.

Pure bone marrow aspirate injection for chronic greater trochanteric pain syndrome: a case report.

There are limited treatment options for patients with a chronic refractory greater trochanteric pain syndrome. Orthobiologic interventions may stimulate tendon healing and improve pain and function in patients who fail the standard conservative treatment. Since the US FDA's new position statement regarding the centrifugation of bone marrow aspirate products as a potentially 'more than minimally manipulated' product, there is a growing concern about the most common bone marrow aspirate concentrate technique. In this case, a 57 year old female with a debilitating chronic greater trochanteric pain syndrome was treated with a pure autologous bone marrow aspirate injection using a novel aspiration technique. The patient showed significant improvements in pain and function without recurrence at 1-year follow-up. This is the first case report to illustrate this novel technique for aspirating pure bone marrow that should comply with the new FDA regulations.

Diagnosis and Treatment of Gouty Tophi in the Patellar Tendon Using Ultrasound-Guided Needle Barbotage: A Case Presentation.

A 73-year-old man presented with nontraumatic debilitating anterior left knee pain. Magnetic resonance imaging suggested a partial patellar tendon tear. However, ultrasound imaging revealed multiple small hyperechoic areas with posterior acoustic shadowing with intermixed hypoechoic fluid within the proximal patellar tendon, consistent with gouty tophi. The patient underwent ultrasound-guided needle barbotage of the tophi. Gout was confirmed by the presence of uric acid crystals in the aspirate. He had immediate pain relief. Ultrasound imaging 6 weeks later demonstrated healing of the tendon without tophi recurrence. At 6-month follow-up, the patient remained asymptomatic. This case highlights a rare cause of knee pain, promotes diagnostic ultrasound, and describes a novel treatment technique for intratendinous tophaceous gout. LEVEL OF EVIDENCE: V.

Aspiration and triamcinolone acetonide injection of wrist synovial cysts in children.

PURPOSE: The aim of this case series report is to assess the effectiveness of aspiration and injection of triamcinolone acetonide for treatment of wrist synovial cysts in children. METHODS: Twenty-one records of pediatric patients with synovial cyst on the wrist treated with aspiration and triamcinolone acetonide injection were selected for analysis of their outcomes. All cases were aspirated and injected at the operating room under mask induction anesthesia. Three categories were used to classify the patients' outcomes: (1) successful treatment with no recurrence, (2) successful treatment with residual sclerotic lump, and (3) recurrence of cyst. RESULTS: Fourteen females and 7 males with an average age of 7.2 years had a mean time with the cyst of 1 year. All children were asymptomatic. After aspiration, 13 (62%) of 21 patients experienced successful treatment of the synovial cyst with no recurrence after a single intervention. Five patients had a residual lump at the site of the cyst (24%), which disappeared after an average of 6 months. Three patients experienced true recurrence of the synovial cyst (14%). Average follow-up was 2.5 years. CONCLUSIONS: Aspiration and injection of triamcinolone accounted for a considerable reduction in recurrence. Aspiration and triamcinolone acetonide injection of wrist synovial cysts is an effective and safe treatment that may be considered as first-line treatment in the pediatric population if there is no resolution after 1 year of observation.
