“…[2,8–13,18,19] The radial nerve palsy occurs in 1.8–18% of cases, on the average in 11% in Ahcan and Ales [2] while it also occurred in 3 out of the 9 cases in our study.…”

“…Unfortunately, it can be the cause of serious fractures within the upper limb which have been reported in the relevant literature. Ahcan and Ales [2] have discussed one case, Heilbronner, Manoli, Morawa [17] 2 cases, Moon, Kim, Suh, Hwang [18] have discussed seven cases. Only in one article, that of Ogawa and Uil [12], have we found an analysis of the fracture location and line, carried out on the basis of 30 cases which are similar to the cases analyzed in our paper.…”

SummaryBackgroundArm wrestling has recently become one of the most popular sports among young people, mainly due to its simplicity and spectacularity. Yet, unfortunately it is also injury prone. The aim of the study was to perform a biomechanical analysis of the forces which act during arm wrestling, as well as to explain the mechanism of the occurrence of humeral fractures of a similar topology as observed on X-rays.Material/MethodsDuring the period 2001 to 2008 nine cases of humeral fractures resulting from arm wrestling were consulted and treated at the Clinic. The assessment of the limb condition included an interview and the examination of the fractured extremity. All the patients underwent surgical treatment, using the method of open reduction and internal fixation. The virtual dynamic model of the upper limb was established on the basis of a series of computer tomography scans of the bone, and literature data. The biomechanical analysis was carried out using the Finite Elements Method (FEM).ResultsThere were five cases of the 12-B1 type in the AO Classification with butterfly fragments in five cases, and four of the 12-A1 type without the butterfly fragment. The maximum bone stress resulting from torsional loading which occurs during arm wrestling amounted to 60 MPa and was located 115 mm above the elbow on the medial - posterior side of the humeral.ConclusionsThe strength analysis carried out during arm wrestling revealed that the forces of the acting muscles significantly exert stresses within the distal third of the humeral.

“…The most commonly occurring serious injury in participants of this sport is spiral fracture of the humeral shaft.

Arm wrestling may cause unusual injuries, which may require operative repair in the sporting individual. Injury to the proximal biceps as a consequence of arm wrestling has not been reported previously. The diagnosis and treatment of a 36-year-old man who sustained a proximal biceps rupture while arm wrestling and his operative management are described.A rm wrestling is a growing sport that requires strength, effective technique and rapid speed of reaction. The most commonly occurring serious injury in participants of this sport is spiral fracture of the humeral shaft. [1][2][3][4] Fracture separation of the medial humeral epicondyle 5 and fractures of the olecranon have also been reported. 6 The mechanism of rotation, coupled with the powerful unopposed contractions of the biceps, is thought to be responsible for many of these injuries.As far as we are aware, injury to the proximal biceps as a consequence of arm wrestling has not been reported previously. We describe an unusual case of proximal biceps rupture in an arm wrestler and describe his subsequent management.Rupture of the proximal biceps tendon occurs in 90-97% of all biceps ruptures and almost exclusively involves the long head. They tend to occur in people aged .50 years and are often associated with rotator cuff tendonitis.7 Rupture of the long head tendon is uncommon in competitive and recreational athletes. A 36-year-old man presented with pain in the anterior compartment of his arm, worse on flexion and supination with a clear long-head rupture of the biceps. The onset of this pain coincided with an episode of competitive arm wrestling. After discussion, he elected to have the tendon repaired to allow his return to the sport.After confirmation of the diagnosis, the biceps lesion was repaired using the technique described by Wiley et al. 10TREATMENT AND SURGICAL TECHNIQUE At arthroscopy, no remnant of the biceps was seen and the arthroscope was removed. A 2-3 cm incision was made along the inferomedial border of the pectoralis major. Blunt dissection between the internervous plane of the pectoralis major and conjoint tendons was next undertaken down to the anterior surface of the humerus. The biceps tendon stump was identified and a number 2 Fiberwire (Arthrex, Naples, Florida, USA) whipstitch was inserted. The tendon stump was then secured to the humerus by means of a Biotenodesis screw (Arthrex). POSTOPERATIVE CARE AND IMMOBILISATIONThe patient was immobilised for 2 weeks in a polysling, at which point physiotherapy was started with a passive range of motion exercises for 2 weeks and an active range of motion exercises for the next 4 weeks. At 6 weeks, lifting of weights ,5 kg was permitted, and at 12 weeks lifting of weights was unrestricted. This patient had no postoperative complications and he had regained the full range of motion and strength by 3 months.
