Introduction

The purpose of this study was to identify the factors contributing to the development and progression of periacetabular osteolytic lesions and to identify which of these lesions can progress at an early stage following THA using repeated computed tomography scans. We also evaluated the accuracy of radiographs in assessing periacetabular osteolysis after THA with uncemented acetabular components and compared it with results of CT analysis.

Methods

CT scans were done in ninety-seven patients (118 hips) who had undergone primary THA between 1996 and 2004 at our hospital at a minimum of two-years postoperatively, from April to August 2006. All the CT images were acquired using high resolution multi-detector row CT (MDCT). The mean age of the patients at the time of surgery was 46.2 years (range, 21–65 years). The mean follow-up at the time of obtaining CT scan was 82.1 months (range, 18–234 months). The second CT scans were obtained in sixty three hips of 49 patients (36 males and 13 females) in 2009. The mean of patient's age was 52.7 years (range, 30 to 76 years). At the time of initial CT scan, the mean duration of implantation was 76.9 months (range, 17–156 months). The volume of periacetabular osteolysis was measured using Rapidia 3D software version. Linear wear of the PE was measured in digitalized radiographs obtained within 3 months of the surgery.

Introduction

We retrospectively evaluated our five years' experience in using Expandable Fixion nail system in tibial diaphyseal fractures.

Materials/Methods

Eighteen cases with closed tibial diaphyseal fracture were identified between January 2006 and January 2011, all treated successfully with Fixion intramedullary nail as a primary osteosynthesis device.

Purpose

Handgrip dynamometry has previously been used to detect pre - operative malnutrition and predict the likelihood of post - operative complications. This study explored whether a relationship exists between pre-operative pinch and power grip strength and length of hospital stay in patients undergoing hip and knee arthroplasty. We investigated whether handgrip dynamometry could be used pre - operatively to identify patients at greater risk of longer inpatient stays.

Methods

164 patients (64 male, 100 female) due to undergo lower limb arthroplasty (83 Total Knee Replacement, 81 Total Hip Replacement) were assessed in pre - admission clinic. Average measurements of pinch grip and power grip were taken from each patient using the Jamar hydraulic dynamometer (Jamar, USA). Duration of each inpatient stay was recorded. Patients with painful or disabling conditions involving the upper limb were excluded. Other clinical variables such as age and ASA grade were investigated as potential confounders of the relationship of interest and adjusted for.

An 83-year-old woman presented with acute weakness in her right hand and wrist extensors and swelling in the proximal right forearm. Nerve conduction studies confirmed compression of posterior introsseous nerve at the level of proximal forearm. MR imaging demonstrated the characteristics of lipoma which extended on the atero-lateral aspect of the right radius neck. The lesion was parosteal lipoma of the proximal radius causing paralysis of the posterior interosseous nerve without sensory deficit. In this case report, posterior inretosseous nerve palsy due to compression of a parostel lipoma was recovered after excision of the lipoma followed by intensive rehabilitation for six month. Surgical excision should be promptly performed to ensure optimal recovery from the nerve paralysis.
