ABSTRACT

Parosteal lipoma is a rare type of lipoma, the incidence being approximately 0.3% of all lipomas. Moreover, parosteal lipoma coexisting with osteochondroma is extremely rare. A few cases with coexistence of osteochondroma and parosteal lipoma have been reported and they were thought to be reactive changes of adjacent bone by parosteal lipoma. However, temporal relationship of these tumors could not be explained. Here, we report a case of parosteal lipoma associated with osteochondroma of the right ilium developed over 6 years, with follow-up radiographs.

ABSTRACT

Distal radioulnar dislocation is commonly associated with radius fracture. Most common dislocation pattern is the dorsal dislocation. We present the unique case of volar dislocation of the distal radioulnar joint blocked by displaced dorsal Barton fracture of distal radius and discuss the injury mechanism and anatomic lesions.

ABSTRACT

BACKGROUND: Some studies have shown significant functional improvement after rotator cuff (RC) repair in elderly patients. However, few studies have reported the healing potential of RC tears in elderly patients. METHODS: Twenty-five patients aged ≥ 75 years who underwent RC repair were enrolled. The mean age at the time of surgery was 78.3 years (range, 75 to 88 years) while the mean follow-up was 36.3 months (range, 18 to 114 months). We evaluated clinical and structural outcomes after RC repair in the retear and healed groups. RESULTS: Of 25 patients, 16 (64%) had healed RC lesions and 9 (36%) had retorn cuff lesions. The retear rate increased significantly with increasing initial tear size (small to medium, 13%; large, 60%; massive, 80%; p = 0.024) but not with increasing age (p = 0.072). The mean visual analog scale (VAS), University of California Los Angeles (UCLA), and Constant scores significantly improved from 5.2, 15.8, and 49.3 preoperatively to 1.4, 31.1, and 71.9 in the healed group and from 6.0, 14.4, and 39.5 preoperatively to 2.4, 28.3, and 63.6 in the retear group at the final follow-up (p < 0.05, respectively). There were no significant differences in clinical outcomes between the 2 groups at the final follow-up. Retear was significantly correlated with initial tear size (p = 0.001; odds ratio [OR], 2.771; 95% confidence interval [CI], 1.394 to 5.509 for large to massive tears) (p = 0.001; OR, 0.183; 95% CI, 0.048 to 0.692 for small to medium tears). CONCLUSIONS: There were significant improvements in clinical outcomes after RC repair in patients ≥ 75 years. Structural integrity after cuff repair did not affect the final clinical outcome. Even in elderly patients aged ≥ 75 years, healing of repaired RC can be expected in cases of small to medium tears. Although the retear rate was relatively high for large to massive tears, clinical outcomes still showed significant improvement.

ABSTRACT

Ulnar tunnel syndrome (UTS) is a compressive neuropathy of the upper extremity that shows various clinical symptoms according to the anatomic region of the compression site. Numerous factors may cause UTS, and most publications are case reports describing various etiologies; thus, obtaining a correct diagnosis is often challenging. Giant cell tumor of the tendon sheath (GCTTS) is well described to be a common benign soft tissue tumor of the hand; however, it is rarely reported to cause UTS. We report a case of GCTTS in Guyon's canal causing UTS that was misdiagnosed as handlebar palsy.

ABSTRACT

Anterior interosseous nerve is purely a motor nerve and supplies flexor pollicis longus, flexor digitorum profundus to the index finger, and pronator quadratus. The etiology and treatment option of anterior interosseous nerve syndrome remain controversial. Bilateral involvement of the anterior interosseous nerve have been described rarely; however, we found no reported case of nonsimultaneous bilateral anterior interosseous nerve palsy associated with the entrapment neuropathy. We present the unique case of delayed anterior interosseous nerve syndrome, 3 years 5 months following an identical event in the opposite extremity and literature review.

ABSTRACT

PURPOSE: As well as patient survival, the restoration of postoperative function such as ambulation is important in limb salvage operations for treatment of malignant bone tumors involving the proximal femur. The authors analyzed clinical outcomes of limb salvage operations using tumor prostheses for metastatic or primary malignant bone tumors in the proximal femur. MATERIALS AND METHODS: From February 2005 to January 2014, 20 cases (19 patients) with malignant bone tumor involving the proximal femur with pain or complicated pathologic fracture were treated with segmental resection and limb salvage operations with tumor prostheses. Mean age was 63.1 years (range 35-86). Fourteen patients were male and six ones were female. The mean follow-up period was 20 months (1-94 months). There were 15 cases of metastatic bone tumor, 4 cases of osteosarcoma, and 1 case of multiple myeloma. The primary tumors of the metastatic bone tumors included 4 lung cancers, 3 hepatocellular carcinomas, and 3 renal cell carcinomas. Other primary tumors were breast cancer, thyroid cancer, colon cancer, prostate cancer, and malignant spindle cell tumor, each in 1 case. Modular tumor prostheses were used in all cases; (Kotz's(R) Modular Tumor prosthesis (Howmedica, Rutherford, New Jersey) in 3 cases, MUTARS(R) proximal femur system (Implantcast, Munster, Germany) in 17 cases). Perioperative pain was assessed with Visual Analogue Scales (VAS). Postoperative functional outcome was assessed with Musculoskeletal Tumor Society (MSTS) grading system. RESULTS: Out of 20 cases (19 patients), 11 cases (10 patients) survived at the last follow-up. Average postoperative survival of the 9 deceased patients was 10.1 months (1-38 months). VAS score improved from pre-operative average of 8.40 (5-10) to 1.35 (0-3) after operation. Average postoperative MSTS function score was 19.65 (65.50%, 7-28). The associated complications were 2 local recurrences, 3 hematomas, 3 infections, 2 scrotal swellings, and 1 dislocation. There was no case of periprosthetic fracture or loosening. CONCLUSION: Limb salvage operation with tumor prosthesis is an appropriate treatment for early pain reduction and functional restoration in malignant bone tumors in the proximal femur with pain an/or complicated pathologic fractures.

ABSTRACT

Acute bilateral renal cortical necrosis (BRCN) is a rare cause of renal failure. It has been reported that contrast-enhanced computed tomography provides characteristic findings of BRCN which correlates well with the histopathology making it an important non-invasive diagnostic modality during early phase of BRCN, improving survival rate and prognosis with early diagnosis and treatment. This report presents a case of 73-year old woman with BRCN due to hemolytic uremic syndrome. The patient recovered from anuria and showed complete recovery to normal renal function of her age and serum creatinine level after early initiation of hemodialysis. Furthermore, a normal radiologic finding of kidney was obtained after 52 days from onset of the disease by contrast-enhanced computed tomography. At present, she is preserved within the normal range renal function without renal replacement therapy.
