RESUMEN

OBJECTIVE: To determine if there was a difference in the risk of post-operative complications associated with the use of different intramedullary (IM) devices in the treatment of unstable AO OTA 31-A trochanteric fractures. DESIGN: Systematic literature review and meta-analysis. METHODS: A systematic literature review was carried out in January 2022 in the Embase, MEDLINE and Cochrane databases. Studies comparing INTERTAN™ to other intramedullary nails for the treatment of AO OTA 31-A trochanteric fractures were selected for inclusion. After data extraction, meta-analyses were carried out on postoperative outcomes, with specific focus placed on unstable fracture patterns. RESULTS: Twenty-three studies were suitable for inclusion, of which seventeen reported on outcomes in unstable fractures. INTERTAN reduced the risk of revision/reoperation by 64% (RR 0.36, 95% CI 0.25 to 0.54, p <0.0001), implant failures by 62% (RR 0.38, 95% CI 0.25 to 0.57, p<0.0001) and hip and thigh pain by 50% (RR 0.50, 95% CI 0.35 to 0.71, p=0.0001) in unstable fractures. No differences were noted between IM nail designs for infection rates, healing time, non-union rates, femoral shortening, or Harris Hip Score. CONCLUSIONS: The INTERTAN IM nail may reduce incidence of implant-related complications, hip and thigh pain, and the need for revision/reoperation without compromising clinical and functional outcomes.

RESUMEN

Osteoid osteomas are benign tumors that may commonly mimic other entities in the upper extremity. The purpose of this study is to describe the clinical and imaging features of osteoid osteomas involving the upper extremity, highlight the difficulties in the diagnosis in the various areas and propose a diagnostic workup. Fourty-eight patients with histologically confirmed osteoid osteoma of the upper extremity treated at the authors' department from 1985 to 2000 were retrospectively reviewed. Data pertinent on the patients' history, lesion location, clinical and imaging characteristics as well as any unique features of individual patients were collected. There were 29 males and 19 females with a mean age of 28 years (range 20-42). The average duration of symptoms before definite diagnosis was 18 months (range 2-62). Pain was the presenting symptom in 46 of 48 patients, whereas swelling was the main complaint in 2 of the patients. Mean pre-operative visual analogue pain scale (VAS), was 8.8 ranging from 5.1 to 9.3. Eight lesions were located in the humerus, 4 in the ulna and 7 in the radius. In the carpal bones, 4 were located in the scaphoid, 4 in the capitate and 5 in the hamate. Seven lesions were located at the metacarpals and 9 lesions at the phalanges (5 proximal, no middle and 4 distal phalangeal lesions). Radiographs alone were sufficient to establish the diagnosis of osteoid osteoma in 32 cases. Bone scans identified a "hot spot" in 16 patients without previous radiographic evidence of a lesion and furthermore, computed tomography was performed in 32 patients to assist in the intraosseous localization of the lesion, and in the pre-operative planning. All patients underwent operative excision of the lesion and the diagnosis was confirmed by histology. Mean follow-up was 28 months (range 25-42). Fourty-three patients had an uneventful recovery. Mean post-operative VAS value was 1.8 ranging from 0 to 3. Osteoid osteoma of the upper extremity often mimics other etiologies and the complex anatomy of the upper extremity, as well as the tendency of patients to relate their symptoms to trauma are factors that easily lead to misdiagnosis or delay in the diagnosis. A high index of suspicion is essential and the diagnosis is based on an accurate clinical assessment and careful selection of imaging studies.

RESUMEN

The authors reviewed 52 patients who underwent Bier's block, as supplementary anesthesia for insufficient axillary block in upper extremity surgical procedures. Prior to proceeding to the Bier's block, the mean value of pain using the visual optical analogue scale (VAS) was 7.0. In 48 of the patients supplementation with the Bier's block was sufficient (mean VAS score of 1.0) and all patients were comfortable throughout the procedure. In the remaining four patients supplementation with narcotics and sedatives via the other i.v. line was required. Intraoperative Bier's block provides a safe and effective alternative way of successfully compensating for an insufficient axillary block in upper extremity surgical procedures.

RESUMEN

Contracture of the collateral ligaments is considered to be an important factor in post-traumatic stiffness of the elbow. We reviewed the results of isolated release of the medial collateral ligament in a series of 14 patients with post-traumatic loss of elbow flexion treated between 1998 and 2002. There were nine women and five men with a mean age of 45 years (17 to 76). They were reviewed at a mean follow-up of 25 months (9 to 48). The operation was performed through a longitudinal posteromedial incision centred over the ulnar nerve. After decompression of the ulnar nerve, release of the medial collateral ligament was done sequentially starting with the posterior bundle and the transverse component of the ligament, with measurement of the arc of movement after each step. If full flexion was not achieved the posterior half of the anterior bundle of the medial collateral ligament was released. At the latest follow-up, the mean flexion of the elbow improved significantly from 96 degrees (85 degrees to 115 degrees ) pre-operatively to 130 degrees (110 degrees to 150 degrees ) at final follow-up (p = 0.001). The mean extension improved significantly from 43 degrees (5 degrees to 90 degrees ) pre-operatively to 22 degrees (5 degrees to 40 degrees ) at final follow-up (p = 0.003). There was a significant improvement in the functional outcome. The mean Broberg and Morrey score increased from a mean of 54 points (29.5 to 85) pre-operatively to 87 points (57 to 99) at final follow-up (p < 0.001). All the patients had normal elbow stability. Our results indicate that partial surgical release of the medial collateral ligament is associated with improved range of movement of the elbow in patients with post-traumatic stiffness, but was less effective in controlling pain.

RESUMEN

alpha 1-Antitrypsin levels were measured in sera of 134 patients with cirrhosis and in 64 with cirrhosis and hepatoma. S-TIC was determined in 105 patients with cirrhosis and in 54 with cirrhosis and hepatoma. The mean alpha 1-at and S-TIC values in patients with cirrhosis were 369.59 +/- 14.072 mg% and 1,808 +/- 0.05 mg/ml respectively. In patients with cirrhosis and hepatoma the mean alpha 1-at level was 406.595 +/- 17.834 mg% and the S-TIC mean values was 2.064 +/- 0.82 mg/ml. Although these values are higher than those found in the healthy controls, the differences are not statistically significant.
