Purpose The aim of this study was to investigate the distribution of intramuscular giant lipomas in the functional compartments of the forearm and to compare their clinical, radiological and histopathological features with those reported in the current literature. Methods The study included 12 patients who were surgically treated for intramuscular lipomas > 5 cm in size located in the forearm that had been confirmed histopathologically between April 2006 and March 2017. Data about the patients with respect to age, sex, affected side, localisation of the lipomas in the forearm functional compartments, size, histopathological features and recurrence were collected. According to the clinical complaints, direct radiography and magnetic resonance imaging were applied. Results The average diameter was 6.5 cm (range: 5.5–9 cm). All lipomas had a well-defined border. All the patients presented with soft-tissue masses that were painless in seven patients. Five patients had nerve compression symptoms. When the lipomas were classified according to the functional compartments of the forearm, six of them were located in the superficial volar compartment, two in the deep volar compartment, two in the deep dorsal compartment and two in the lateral compartment. All lipomas were surgically removed by marginal excision. None had complications or recurrence at a mean of 6.5 years follow-up (range: 1–12 years) after surgery. Conclusions Intramuscular lipoma is a relatively uncommon tumour, especially in the forearm. Because of the proximity to the neurovascular structures in the forearm, excision of lipomas should be performed with care and include wide incisions. Additionally, knowing the anatomical features of the compartment where the lipoma is localised in the forearm is important in planning surgery to enable easier dissection of the lipoma and lessen the risk of damage to adjacent neurovascular structures.

Objective: The present retrospective study evaluated the clinical and radiologic results of patients who underwent complete curettage and autologous bone grafting for hand-located isolated enchondromas with a minimum follow-up period of one year. Patients and Methods: Thirty-two patients with a follow-up period of at least 12 months who underwent operation between August 2010 and October 2018 due to the presence of solitary enchondroma of the hand were included in the study. All patients underwent complete curettage and filling of the defect via autologous bone grafting. Autologous bone graft was harvested from the iliac crest and distal radius in 24 and eight patients, respectively. The patients underwent radiography on the first postoperative visit and at six weeks, 12 weeks, and annually. The range of movement of the finger joint was evaluated by comparing it with the healthy contralateral side. Functional outcomes and radiologic outcomes were evaluated. The frequency of complications and recurrences were established. Results: Twelve patients were male and 20 were female. The average age was 34 (range: 16-56) years. The most common digit involved was the little finger (nine cases, 28.125%); the proximal phalanx was the most common location (17 cases, 53.125%). Control radiography in the sixth week revealed graft consolidation in all patients. No case of nonunion or recurrence was detected clinically or radiologically, with a mean follow-up period of 54 (range: 12-96) months. Functional outcomes were classified as excellent in 28 patients and as good in four patients. The final radiographic appearances included Tordai's group 1 in 28 bones and group 2 in four bones. Conclusion: Curettage and autologous bone grafting are safe, costless, and effective treatment options for hand enchondroma, with satisfactory functional and radiographic outcomes. Harvesting bone graft from the distal radius provides a shorter length of hospital stay and lower complication rates compared to obtaining the graft from the iliac crest.

We, herein, presented a rare case of bilateral brachial artery infiltration by tumoral calcinosis located on both elbows. A 58-year-old man presented with a history of painless, palpable solid mass restricting the range of motion of both elbows. These masses were located on the anterior aspect of the elbows and gradually enlarged. After clinical, laboratory and radiological examinations, tumoral calcinosis was suspected, and excisional biopsy was planned for a definite diagnosis. Surgery was first performed on the left elbow. The median nerve was found to be compressed but not infiltrated by the mass. Interestingly, the brachial artery was totally infiltrated throughout the entire mass. Occlusion was observed in the brachial artery located within the mass. The tumor on the left elbow, 8.5 × 5.5 × 2.5 cm in size, was totally excised with approximately 12-cm brachial artery segment. The artery was resected until the healthy tissue was reached. The defect was reconstructed with saphenous vein graft obtained from the ipsilateral lower extremity. The same surgical procedure was performed on the right elbow after 3 months. The tumor size on the right elbow was 7 × 3.5 × 1.7 cm. Approximately 15-cm brachial artery segment was excised, and the defect was reconstructed with saphenous vein graft. Tumoral calcinosis is a rare benign condition that can be located in close relationship with neurovascular structures. In such cases, detailed neurologic and vascular examination, including imaging modalities, for arterial flow is essential to establish a more accurate surgical plan and avoid any unexpected situation during surgery.

BACKGROUND: This study aimed to examine the relationships between the initial anatomic severity of hand, wrist and forearm injuries, as evaluated by the Modified Hand Injury Severity Score (MHISS), and each of the following parameters: disability rating and time to return to work. METHODS:In this study, 94 patients who underwent operations due to acute hand, wrist and forearm injuries were included. MHISS was used to assess the severity of the injury. Disability rates of the patients were calculated six months after injury in accordance with the 'Regulation on Disability Criteria, Classification and Health Board Reports to be Given to Disabled People'. The time to return to work was defined as the length of time (in days) between the injury and the patient's return to work. Spearman rank correlation analysis was performed to analyse correlations between the MHISS and each of the following: disability rates and time to return to work. RESULTS:The mean overall MHISS was 125.23 (5-880). The mean overall upper extremity disability ratio (UEDR) was 17.64±22.6 (range: 0-94), and the mean overall total body disability ratio (TBDR) was 10.57±13.45 (range: 0-56). Among the study population, 87 (92.6%) patients were able to return to their jobs. The mean overall time to return to work was 138.69 (range: 35-365 days). A statistically significant correlation was found between MHISS and UEDR, TBDR and time to return to work and UEDR, TBDR (p<0.001). CONCLUSION:As a result, as the initial injury severity increased, greater disability remained and the time to return to work increased. Predicting prognosis by determining the injury severity in the initial evaluation of patients may be important in predicting a patient's future permanent disability level, which can contribute to maintaining patient expectations at a reasonable level, thereby aiding in psychosocial support.
